•Individual - Protection(1) up $50 million: Higher premiums reflecting good sales momentum during the past year in Asia, and improved insurance experience in Canada and the U.S.

2 Sun Life Financial Inc. Second Quarter 2023 EARNINGS NEWS RELEASE

Asset Management: A global leader in both public and alternative asset classes through MFS and SLC Management

Asset Management underlying net income of $296 million increased $1 million from prior year, driven by:

•MFS up $2 million (down US$10 million): Higher net investment income and the impacts from foreign exchange translation was largely offset by lower average net assets ("ANA") reflecting equity market declines over the past year and net outflows. The MFS pre-tax net operating profit margin(1) was 37% for Q2'23, compared to 36% in the prior year.

•SLC Management down $1 million: Fee-related earnings(1) increased 19% driven by higher AUM, reflecting strong capital raising and deployment across the platform and the AAM acquisition(2). Fee-related earnings margin(1) for Q2'23 was 24% compared to 23% in the prior year. Underlying net income was in line with prior year, with the increase in fee-related earnings offset by higher earned operating income in the prior year that did not repeat.

Reported net income of $248 million decreased $50 million or 17%, driven by fair value changes in management's ownership of MFS shares and losses on real estate investments held in the SLC Management surplus account.

Foreign exchange translation led to an increase of $13 million and $12 million in underlying net income and reported net income, respectively.

Asset Management ended Q2'23 with $998 billion of AUM, consisting of $780 billion (US$589 billion) in MFS and $218 billion in SLC Management. Total Asset Management net outflows of $3.3 billion in Q2'23 reflected MFS net outflows of $5.3 billion (US$4.0 billion) partially offset by SLC Management net inflows of $2.0 billion.

Our Asset Management businesses continue to maintain a strong focus on sustainable investing. During the second quarter, BentallGreenOak (“BGO”) received Gold Recognition in the 2023 Green Lease Leaders program organized by the Institute for Market Transformation and the U.S. Department of Energy Better Buildings Alliance. InfraRed Capital Partners (“InfraRed”) continues to invest capital in companies helping to build a sustainable future. For example, in Q2’23, InfraRed announced an investment in JOLT(3), an e-mobility company. InfraRed’s investment in JOLT’s rapid electric vehicle charging infrastructure supports a low carbon future and supports its target of achieving 50% of AUM(4) invested in climate solutions by 2025.

Advisors Asset Management, Inc. (“AAM”), a U.S. retail distribution affiliate of SLC Management which we acquired last quarter, announced it will distribute BGO IREIT(5), a non-traded real estate investment trust launched by BGO, demonstrating the strategic benefit from the AAM acquisition.

Canada: A leader in health, wealth, and insurance

Canada underlying net income of $372 million increased $73 million or 24% from prior year, reflecting:

•Wealth & asset management in line with prior year: Increase in investment income driven by higher volume and yields, largely offset by higher expenses.

•Group - Health & Protection up $48 million: Better disability experience reflecting higher margins, lower claims volumes, and shorter claims durations.

•Individual - Protection up $25 million: Improved insurance experience as well as higher investment contributions.

Reported net income of $210 million decreased $266 million or 56% from prior year, reflecting market-related impacts primarily from interest rates and real estate experience, partially offset by the increase in underlying net income.

Canada's sales(6):

•Wealth sales & asset management gross flows of $3 billion were down 6%, reflecting lower defined benefit solution sales partially offset by higher defined contribution sales in Group Retirement Services ("GRS").

•Group sales of $153 million were up 66%, reflecting higher large case sales.

•Individual sales of $154 million were up 22%, reflecting higher participating whole life insurance sales.

We continue to deliver on our strategy of strengthening and expanding our health business. We provide Canadians with the support they need to take action throughout their health journey, helping to prevent and mitigate health risks and live healthier lives. During the second quarter, we launched Lumino Health Pharmacy, a new online pharmacy app, which will help Clients consult a knowledgeable pharmacist by chat or a phone call and have medications delivered to their door free of charge. This service helps Clients to keep track of their medications, usage, refills, and sends them important notifications regarding their prescriptions.

In July, we entered into an agreement to acquire Dialogue Health Technologies Inc. (“Dialogue”), Canada’s premier virtual health care and wellness platform, providing affordable on-demand access to quality care, which will help us empower Canadians with access to the care they need from the convenience of their home.

U.S.: A leader in health and benefits

U.S. underlying net income of US$160 million increased US$58 million or 57% ($215 million increased $81 million or 60%) from prior year, driven by:

•Group - Health & Protection up US$46 million: Strong performance across all businesses including good premium growth, contribution from the DentaQuest acquisition, higher investment contributions and favourable experience. Experience in the quarter included higher medical stop-loss margins and favourable group disability.

•Individual - Protection up US$12 million: The inclusion of the UK payout annuity business(1) and insurance experience. Mortality experience in the quarter improved compared to the prior year.

•Higher earnings on surplus reflecting an increase in net interest income from higher rates.

Reported net income of US$133 million increased US$20 million or 18% ($175 million increased $26 million or 17%) from prior year, reflecting the increase in underlying net income and favourable ACMA(2), partially offset by a prior year gain on the sale-leaseback of the Wellesley office.

Foreign exchange translation led to an increase of $11 million and $10 million in underlying net income and reported net income, respectively.

U.S. group sales of $484 million were up $271 million, driven by higher dental(3) and medical stop-loss sales.

We continue to take action to support our strategic priority to help Clients access the health care and coverage they need. In our Dental business, we expanded the Advantage Dental+ care practices with two new offices in Texas. These practices are in areas where access to quality oral health care is a challenge for children with Medicaid coverage. We also recorded the largest Medicare Advantage sale in DentaQuest history, bringing dental sales to approximately $580 million since closing the DentaQuest acquisition on June 1, 2022.

We also announced a relationship with Philadelphia-based Independence Health Group to exclusively provide medical stop-loss insurance for their self-funded group medical clients to help protect against large, unpredictable health care costs. This supports our strategy of partnering with other insurers and health plans to expand our market presence and deliver our expertise to additional Clients.

Asia: A regional leader focused on fast-growing markets

Asia underlying net income of $150 million increased $32 million or 27% from prior year, driven by:

•Wealth & asset management down $2 million: Lower fee-based earnings reflecting lower AUM in the Philippines.

•Individual - Protection up $38 million: Higher premiums reflecting good sales momentum during the past year, and improved expenses and lapse experience in our joint ventures. This was partially offset by less favourable morbidity experience in Hong Kong.

•Regional office expenses & other $(4) million increased net loss: In line with the prior year.

Reported net income of $122 million increased $115 million from prior year, driven by market-related impacts, largely from interest rates partially offset by real estate experience, and the increase in underlying net income.

Foreign exchange translation led to an increase of $3 million in underlying net income and reported net income.

Asia's sales(4):

•Wealth sales & asset management gross flows of $2 billion were down 51%, primarily reflecting lower money market fund sales in the Philippines.

•Individual sales of $450 million were up 55%, driven by higher sales in Hong Kong, China and India.

New business CSM of $118 million in Q2'23, compared to $70 million in the prior year, was primarily driven by sales and favourable product mix in High-Net-Worth and Hong Kong.

We continue to make progress on our strategic priorities of establishing digital leadership and leveraging distribution excellence. In Hong Kong, we introduced eSunPro, a new digital health care service platform which provides comprehensive, one-stop care and assistance to Clients, ranging from services at the point of diagnosis to post-treatment care, enabling them to access advanced treatment and support throughout their recovery process.

We strive to enhance Clients’ experience and make it easier for them to do business with us. During the second quarter, we opened the Sun Gateway prestige Client center (“The Center”) in Hong Kong. The Center offers High-Net-Worth Clients professional insurance consultancy and one-stop financial products and services, with a dedicated team of onsite financial advisors and client service representatives catering to their wealth management and protection needs as they evolve through different life stages.

Sun Life has operations in a number of markets worldwide, including Canada, the United States, the United Kingdom, Ireland, Hong Kong, the Philippines, Japan, Indonesia, India, China, Australia, Singapore, Vietnam, Malaysia and Bermuda.

Sun Life Financial Inc. trades on the Toronto (TSX), New York (NYSE) and Philippine (PSE) stock exchanges under the ticker symbol SLF.


A. How We Report Our Results

On January 1, 2023 we adopted IFRS 17 Insurance Contracts ("IFRS 17"), which replaces IFRS 4 Insurance Contracts. IFRS 17 establishes the principles for the recognition, measurement, presentation, and disclosure of insurance contracts. On January 1, 2023, we also adopted IFRS 9 Financial Instruments ("IFRS 9"), which replaces IAS 39 Financial Instruments: Recognition and Measurement. The nature and effects of the key changes in our critical accounting policies and estimated impacts from the adoption of the new standards are summarized in section
L - Changes in Accounting Policies in this document. For more information including the measurement and classification of opening balances, refer to Note 2 of our Interim Consolidated Financial Statements for the period ended June 30, 2023.

Unless otherwise noted, all amounts are in Canadian dollars. Amounts in this document are impacted by rounding.

Note to Readers: 2022 Restated Results on Adoption of IFRS 17 and IFRS 9

2022 results have been restated for the adoption of IFRS 17 and the related IFRS 9 classification overlay (“the new standards”). The restated results may not be fully representative of our future earnings profile, as we were not managing our asset and liability portfolios under the new standards. The majority of the actions taken to re-balance asset portfolios and transition asset-liability management execution to an IFRS 17 basis occurred in Q1'23. Accordingly, analysis based on 2022 comparative results may not necessarily be indicative of future trends, and should be interpreted with this context. Using sensitivities to analyze the outlook for market risk and related impacts (e.g., interest rate sensitivities) will be more representative starting with the sensitivities disclosed for Q1’23 and onward in section I - Risk Management in each quarter's respective MD&A document. Certain 2022 restated results and 2023 interim results in the Drivers of Earnings and CSM Movement Analysis were refined to more accurately reflect how management views the business. As these results are not audited, or have not yet been audited, they may still be subject to change.

MANAGEMENT'S DISCUSSION AND ANALYSIS Sun Life Financial Inc. Second Quarter 2023 7

Underlying net income by Business Types

Sun Life has a diversified mix of businesses and our earnings by business type support the understanding and analysis of our results:

•Wealth & asset management: Sun Life’s wealth & asset management businesses generate recurring fee income and/or spread on investment products.

•Group - Health & Protection: Group businesses provide health and protection benefits to employer and government plan members. The products generally have shorter-term coverage periods, and more frequent repricing. The revenues are driven by premiums for coverage provided as well as fee-based earnings (i.e., Administrative Services Only plans, and dental fees).

•Individual - Protection: Generally, individual protection business has a longer-term profitability profile and is more sensitive to experience trends. The premiums include a margin for providing protection and are invested to earn a return over the expected amounts required to fulfill insurance liabilities.

The following provides an overview of the business types in Sun Life's business segments/business groups:

1. Use of Non-IFRS Financial Measures

We report certain financial information using non-IFRS financial measures, as we believe that these measures provide information that is useful to investors in understanding our performance and facilitate a comparison of our quarterly and full year results from period to period. These non-IFRS financial measures do not have any standardized meaning and may not be comparable with similar measures used by other companies. For certain non-IFRS financial measures, there are no directly comparable amounts under IFRS. These non-IFRS financial measures should not be viewed in isolation from or as alternatives to measures of financial performance determined in accordance with IFRS. Additional information concerning non-IFRS financial measures and, if applicable, reconciliations to the closest IFRS measures are available in section N - Non-IFRS Financial Measures in this document and the Supplementary Financial Information package on www.sunlife.com under Investors - Financial results and reports.

2. Forward-looking Statements

Certain statements in this document are forward-looking statements within the meaning of certain securities laws, including the "safe harbour" provisions of the United States Private Securities Litigation Reform Act of 1995 and applicable Canadian securities legislation. Additional information concerning forward-looking statements and important risk factors that could cause our assumptions, estimates, expectations and projections to be inaccurate and our actual results or events to differ materially from those expressed in or implied by such forward-looking statements can be found in section O - Forward-looking Statements in this document.

3. Additional Information

Additional information about SLF Inc. can be found in the Consolidated Financial Statements, the annual and interim MD&A, and SLF Inc.'s Annual Information Form ("AIF") for the year ended December 31, 2022. These documents are filed with securities regulators in Canada and are available at www.sedarplus.ca.

Quarterly Comparison - Q2'23 vs. Q2'22

Underlying net income(1) of $920 million increased $112 million or 14%, driven by:

•Individual - Protection(1) up $50 million: Higher premiums reflecting good sales momentum during the past year in Asia, and improved insurance experience in Canada and the U.S.

•Corporate expenses & other(1) $(59) million increased net loss driven by higher operating expenses including incentive compensation and an increase in debt financing costs.

•Higher earnings on surplus reflecting an increase in realized gains and net interest income from higher rates.

Reported net income of $660 million decreased $270 million or 29%, driven by:

•Market-related impacts primarily reflecting interest rates and real estate investments(3);

•Prior year gain on the sale-leaseback of the Wellesley office in the U.S.; and

•Fair value changes in management's ownership of MFS shares; partially offset by

•The increase in underlying net income.

10 Sun Life Financial Inc. Second Quarter 2023 MANAGEMENT'S DISCUSSION AND ANALYSIS

Foreign exchange translation led to an increase of $27 million and $25 million in underlying net income and reported net income, respectively.

Underlying ROE was 17.7% and reported ROE was 12.7% (Q2'22 - 16.7% and 19.2%, respectively).

1.Market-related impacts

Market-related impacts represent the difference between actual versus expected market movements. Market-related impacts resulted in a decrease of $220 million to reported net income, reflecting real estate investments and interest rate impacts. The decline in total value of real estate investments was driven by investment experience in Canada and Asia and losses in the SLC Management surplus account from capitalization rate expansion. Interest rate impacts primarily reflected non-parallel curve changes during the quarter.

2.Assumption changes and management actions

The net impact of assumption changes and management actions was an increase of $7 million to reported net income reflecting various small enhancements.

3.Other adjustments

Other adjustments decreased reported net income $47 million, reflecting DentaQuest integration costs and amortization of acquired intangible assets, partially offset by a gain on the sale of Sun Life UK(1).

4.Experience-related items

In the second quarter of 2023, notable experience items included:

•Favourable mortality experience largely in Asia; and

•Favourable morbidity experience largely in Canada and in U.S. medical stop-loss.

5.Income taxes

Our statutory tax rate is impacted by various tax items, such as lower taxes on income subject to tax in foreign jurisdictions, tax-exempt investment income, and other sustainable tax benefits.

The Q2'23 effective income tax rate(2) on underlying net income and reported net income was 19.7% and 14.6% respectively.

6.Impacts of foreign exchange translation

Foreign exchange translation led to an increase of $27 million and $25 million in underlying net income and reported net income, respectively.

Year-to-Date Comparison - Q2'23 vs. Q2'22

Underlying net income of $1,815 million increased $287 million or 19%, driven by:

•Wealth & asset management down $12 million: Lower fee-based earnings in MFS, Canada, and Asia, reflecting equity market declines over the past year, as well as higher expenses in Canada, partially offset by higher investment income driven by volume growth and an increase in yields.

•Group - Health & protection up $302 million: Strong performance driven by good premium growth, better disability experience in Canada and the U.S., as well as DentaQuest contributions.

•Individual - Protection up $92 million: Higher premiums reflecting good sales momentum during the past year, and improved insurance experience in Canada and Asia.

•Corporate expenses & other $(95) million increased net loss driven by higher operating expenses including incentive compensation and an increase in debt financing costs.

•Higher earnings on surplus reflecting an increase in realized gains and net interest income from higher rates.

Reported net income of $1,466 million decreased $129 million or 8%, driven by:

•Market-related impacts primarily reflecting interest rates and real estate investments(3);

•Prior year gain on the sale-leaseback of the Wellesley office in the U.S.; and

•Fair value changes in management's ownership of MFS shares; largely offset by

•The increase in underlying net income; and

•Gain on the sale of the sponsored markets business in Canada(4).

Foreign exchange translation led to an increase of $59 million and $53 million to underlying net income and reported net income, respectively.

Underlying ROE was 17.5% and reported ROE was 14.2% (2022 - 15.6% and 16.3%, respectively).

(1)On April 3, 2023, we completed the sale of SLF of Canada UK Limited to Phoenix Group Holdings plc ("the sale of Sun Life UK").

(2)Our effective income tax rate on reported net income is calculated using Total income (loss) before income taxes, as detailed in Note 10 in our Interim Consolidated Financial Statements for the period ended June 30, 2023. Our effective income tax rate on underlying net income is calculated using pre-tax underlying net income, as detailed in section N - Non-IFRS Financial Measures in this document, and the associated income tax expense.

(4)On February 1, 2023, we completed the sale of the sponsored markets business from Sun Life Assurance, a wholly owned subsidiary of SLF Inc., to Canadian Premier Life Insurance Company ("sale of the sponsored markets business").

MANAGEMENT'S DISCUSSION AND ANALYSIS Sun Life Financial Inc. Second Quarter 2023 11

1.Market-related impacts

Market-related impacts represent the difference between actual versus expected market movements. Market-related impacts resulted in a decrease of $284 million to reported net income, reflecting real estate investments and interest rate impacts. The decline in total value of real estate investments was driven by investment experience in Canada and Asia and losses in the SLC Management surplus account from capitalization rate expansion. Interest rate impacts primarily reflected non-parallel curve changes during the year.

2.Assumption changes and management actions

The net impact of assumption changes and management actions was an increase of $2 million to reported net income reflecting various small enhancements.

3.Other adjustments

Other adjustments decreased reported net income $67 million, reflecting DentaQuest integration costs, amortization of acquired intangible assets, and SLC Management acquisition-related costs, partially offset by gains on the sale of the sponsored markets business in Canada and the sale of Sun Life UK.

4. Experience-related items

Notable experience items in the current year included:

•Favourable morbidity experience largely in Canada and in U.S. medical stop-loss; and

•Other experience was favourable reflecting various smaller items.

5.Income taxes

1. Life Insurance Capital Adequacy Test

The Office of the Superintendent of Financial Institutions has developed the regulatory capital framework referred to as the Life Insurance Capital Adequacy Test for Canada. LICAT measures the capital adequacy of an insurer using a risk-based approach and includes elements that contribute to financial strength through periods when an insurer is under stress as well as elements that contribute to policyholder and creditor protection wind-up.

SLF Inc. is a non-operating insurance company and is subject to the LICAT guideline. Sun Life Assurance, SLF Inc.'s principal operating life insurance subsidiary, is also subject to the LICAT guideline.

SLF Inc.'s LICAT ratio of 142% and Sun Life Assurance's LICAT ratio of 139% as at January 1, 2023 increased 12 percentage points compared to December 31, 2022, from the transition to IFRS 17. The largest driver of change was the reduction in the LICAT base solvency buffer ("BSB") scalar from 1.05 to 1.0 which contributed seven percentage points.

SLF Inc.'s LICAT ratio of 148% as at June 30, 2023 increased six percentage points compared to January 1, 2023, driven by reported net income, the sale of Sun Life UK, and capital optimization. This was partially offset by shareholder dividend payments.

Sun Life Assurance's LICAT ratio of 139% as at June 30, 2023 was consistent to January 1, 2023, as the impact from reported net income and sale of Sun Life UK were offset by dividend payments to SLF Inc.

The Sun Life Assurance LICAT ratios in both periods are well above OSFI's supervisory ratio of 100% and regulatory minimum ratio of 90%.

MANAGEMENT'S DISCUSSION AND ANALYSIS Sun Life Financial Inc. Second Quarter 2023 15

2. Capital

On transition to the new standards, total capital of $40.6 billion as at January 1, 2023 increased $4.4 billion compared to December 31, 2022 driven by the establishment of the CSM, which includes transfers from Common shareholders' equity and equity in the participating account to the CSM.

Our total capital consists of subordinated debt and other capital instruments, CSM, equity in the participating account and total shareholders' equity which includes common shareholders' equity, preferred shares and other equity instruments, and non-controlling interests. As at June 30, 2023, our total capital was $41.3 billion, an increase of $0.7 billion compared to January 1, 2023. The increase to total capital included reported net income of $1,466 million, an increase of $393 million in CSM and net unrealized gains on fair value through other comprehensive income ("FVOCI") assets of $82 million. This was partially offset by the payment of $863 million of dividends on common shares of SLF Inc. ("common shares"), unfavourable impacts of foreign exchange translation of $322 million included in other comprehensive income (loss) ("OCI") and the impact related to the acquisition of AAM of $158 million(1).

Our capital and liquidity positions remain strong with a LICAT ratio of 148% at SLF Inc., a financial leverage ratio of 23.3%(2) and $2.0 billion in cash and other liquid assets(2) as at June 30, 2023 in SLF Inc.(3) (December 31, 2022 - $1.1 billion).

Subsequent Events

For additional information, refer to Note 17 of our Interim Consolidated Financial Statements for the period ended June 30, 2023.

Effective July 1, 2023 we commenced our 15-year exclusive bancassurance partnership with Dah Sing Bank ("Dah Sing"). Under this

partnership, Sun Life will be the exclusive provider of life insurance solutions to Dah Sing's approximately 570,000 retail banking customers, helping to fulfill their savings and protection needs at different life stages. This is Sun Life's first exclusive bancassurance partnership in Hong Kong and will be a valuable complement to our existing network of over 2,500 expert insurance advisors. Hong Kong is a thriving life insurance hub in Asia and bancassurance is a key distribution channel, accounting for more than 50% of the life insurance distribution mix in Hong Kong.

On July 4, 2023, SLF Inc. issued $500 million principal amount of Series 2023-1 Subordinated Unsecured 5.50% Fixed/Floating Debentures due 2035. Sun Life intends to use an amount equal to the net proceeds from the offering to finance or refinance, in whole or in part, eligible assets as defined in our Sustainability Bond Framework.

On July 21, 2023, SLF Inc. announced its intention to redeem all of the outstanding $1 billion principal amount of Series 2016-2 Subordinated Unsecured 3.05% Fixed/Floating Debentures, in accordance with the redemption terms attached to such debentures. The redemption will be funded from existing cash and liquid assets. SLF Inc. intends to redeem the debentures on September 19, 2023.

On July 26, 2023, we announced that we entered into an agreement to acquire Dialogue Health Technologies Inc. ("Dialogue") in which our current ownership interest will increase from approximately 23% to approximately 97% for estimated cash proceeds of $277 million (for equity not currently owned by Sun Life or rolled by certain members of Dialogue's executive management). Dialogue is a Canadian based health and wellness virtual care platform and will form a part of our Canada business segment. The transaction is expected to close in 2023, subject to satisfaction of customary closing conditions.

On August 8, 2023, SLF Inc. announced that, subject to the approval of OSFI and the Toronto Stock Exchange (“TSX”), it intends to launch a normal course issuer bid to purchase up to 17 million of its common shares ("the NCIB”). Subject to receipt of regulatory and stock exchange approvals, the NCIB is expected to commence on August 21, 2023 and continue until August 20, 2024, or such earlier date as SLF Inc. may determine. Purchases under the NCIB may be made through the facilities of the TSX, other Canadian stock exchanges and/or alternative Canadian trading platforms, at prevailing market rates. Subject to regulatory approval, purchases under the NCIB may also be made by way of private agreements or share repurchase programs under issuer bid exemption orders issued by securities regulatory authorities. Any purchases made under an exemption order issued by a securities regulatory authority will generally be at a discount to the prevailing market price. The actual number of common shares purchased under the NCIB, and the timing of such purchases (if any), will be determined by SLF Inc. Any common shares purchased by SLF Inc. pursuant to the NCIB will be cancelled or used in connection with certain equity settled incentive arrangements. The NCIB will provide the Company with the flexibility to acquire common shares in order to return capital to shareholders as part of its overall capital management strategy.

18 Sun Life Financial Inc. Second Quarter 2023 MANAGEMENT'S DISCUSSION AND ANALYSIS

Profitability

Quarterly Comparison - Q2'23 vs. Q2'22

Asset Management underlying net income of $296 million increased $1 million driven by:

•SLC Management down $1 million: Fee-related earnings(1) increased 19% driven by higher AUM, reflecting strong capital raising and deployment across the platform and the AAM acquisition. Fee-related earnings margin(1) and pre-tax net operating profit margin(1) for Q2'23 were 24% and 20%, respectively (Q2'22 - 23% and 24%, respectively). Underlying net income was in line with prior year, with the increase in fee-related earnings offset by higher earned operating income in the prior year that did not repeat.

Asset Management reported net income of $248 million decreased $50 million or 17%, driven by fair value changes in management's ownership of MFS shares and losses on real estate investments held in the SLC Management surplus account.

Foreign exchange translation led to an increase of $13 million and $12 million in underlying net income and reported net income, respectively.

Year-to-Date Comparison - Q2'23 vs. Q2'22

Asset Management underlying net income of $578 million decreased $38 million or 6% driven by:

•MFS down $25 million (US$43 million): Lower ANA reflecting equity market declines over the past year and net outflows, partially offset by higher net investment income and lower variable compensation costs.

•SLC Management down $13 million: Fee-related earnings(1) increased 23% driven by higher AUM, reflecting strong capital raising and deployment across the platform and the AAM acquisition. Underlying net income was down from prior year as fee-related earnings growth was more than offset by higher financing costs on seed investments and higher compensation expenses.

Asset Management reported net income of $502 million decreased $107 million or 18% driven by the decline in underlying net income, fair value changes in management's ownership of MFS shares, losses on real estate investments held in the SLC Management surplus account, and SLC Management acquisition-related costs.

Foreign exchange translation led to an increase of $29 million and $27 million in underlying net income and reported net income, respectively.

Growth

Asset Management AUM of $997.8 billion increased $45.9 billion or 5% from December 31, 2022 driven by:

•Net asset value changes of $49.7 billion; and

•AUM driven by the AAM acquisition of $5.2 billion; partially offset by

•Net outflows of $5.8 billion; and

•Client distributions of $3.2 billion.

MFS' AUM increased US$41.3 billion or 8% from December 31, 2022, driven by:

•Increase in asset values from higher equity markets of US$49.5 billion, partially offset by net outflows of US$8.2 billion.

In Q2'23, 98%, 92%, and 20% of MFS' U.S. retail mutual fund assets ranked in the top half of their Morningstar categories based on ten-, five- and three-year performance, respectively.

SLC Management's AUM increased $8.4 billion or 4% from December 31, 2022 driven by:

•Net inflows of $5.3 billion, the AAM acquisition of $5.2 billion, and asset value changes of $1.2 billion, partially offset by Client distributions of $3.2 billion.

•Net inflows were comprised of capital raising and Client contributions, totaling $10.7 billion, partially offset by outflows of $5.4 billion.

SLC Management's FE AUM increased $6.6 billion or 4% from December 31, 2022, driven by:

•The AAM acquisition of $5.2 billion and net inflows of $4.6 billion, partially offset by Client distributions of $2.8 billion and asset value changes of $0.3 billion.

•Net inflows were comprised of capital deployment and Client contributions, totaling $9.3 billion, partially offset by outflows of

$4.7 billion.

•Regional office expenses & other $(4) million increased net loss: In line with the prior year.

Reported net income of $122 million increased $115 million, driven by market-related impacts, largely from interest rates partially offset by real estate experience, and the increase in underlying net income.

Foreign exchange translation led to an increase of $3 million in underlying net income and reported net income.

Year-to-Date Comparison - Q2'23 vs. Q2'22

Underlying net income of $291 million increased $40 million or 16%, driven by

•Wealth & asset management down $8 million: Lower fee-based earnings largely reflecting equity market declines over the past year, and lower AUM in the Philippines.

•Individual - Protection up $49 million: Higher premiums reflecting good sales momentum during the past year, improved mortality, and contributions from joint ventures driven by favourable policyholder behaviour and expense experience, partially offset by lower investment contributions.

•Regional office expenses & other $(1) million increased net loss: In line with the prior year.

MANAGEMENT'S DISCUSSION AND ANALYSIS Sun Life Financial Inc. Second Quarter 2023 23

Reported net income of $256 million increased $138 million, driven by market-related impacts largely from interest rates partially offset by real estate experience, and the increase in underlying net income.

Foreign exchange translation led to an increase of $6 million and $10 million in underlying net income and reported net income, respectively.

Growth

Quarterly Comparison - Q2'23 vs. Q2'22

Asia's sales included:

•Wealth sales & asset management gross flows of $1.6 billion were down 52%(1), primarily reflecting lower money market fund sales in the Philippines.

•Individual sales of $450 million were up 51%(1), driven by higher sales in Hong Kong, China and India.

New business CSM of $118 million, compared to $70 million in the prior year, was primarily driven by sales and favourable product mix in High-Net-Worth and Hong Kong.

Profitability

Quarterly Comparison - Q2'23 vs. Q2'22

Underlying net loss was $113 million compared to underlying net loss of $38 million in the prior year, reflecting higher operating expenses including incentive compensation and an increase in debt financing costs, the impact from the sale of Sun Life UK, partially offset by higher investment income from surplus assets.

Year-to-Date Comparison - Q2'23 vs. Q2'22

Underlying net loss was $194 million compared to underlying net loss of $85 million in the prior year, reflecting higher operating expenses including incentive compensation and an increase in debt financing costs, the impact from the sale of Sun Life UK, partially offset by higher investment income from surplus assets.

Reported net loss was $174 million compared to reported net loss of $69 million in the prior year, reflecting the change in underlying net loss and market-related impacts, partially offset by a gain on the sale of Sun Life UK.

Sale of Sun Life UK

On April 3, 2023 we completed the sale of SLF of Canada UK Limited ("Sun Life UK") to Phoenix Group Holdings plc ("Phoenix Group") for approximately $418 million (£248 million). Sun Life UK managed life and pension policies as well as payout annuities for UK Clients, was closed to new sales and operated as a run-off business since 2001. Under the agreement, we will retain our economic interest in the payout annuities business through a reinsurance treaty, which, effective Q2'23, is recorded in In-force Management within the U.S. business group. Phoenix Group is the UK's largest long-term savings and retirement business, with £259 billion(1) of assets under administration and approximately 13 million customers. As part of the sale, we will establish a long-term partnership to become a strategic asset management partner to Phoenix Group. Our asset management companies, MFS and SLC Management, will continue to manage approximately $8 billion of Sun Life UK's general account. In addition, Phoenix Group has set a goal to invest approximately US$25 billion in North American public and private fixed income and alternative investments over the next five years. MFS and SLC Management will be material partners to Phoenix Group in achieving this goal. In Q3'22, we recognized an impairment charge pertaining to the attributed goodwill that was not expected to be recovered through the sale. In Q2'23, we recognized a gain of $19 million in reported net income. For additional information, refer to Note 3 of our Interim Consolidated Financial Statements for the period ended June 30, 2023.

MANAGEMENT'S DISCUSSION AND ANALYSIS Sun Life Financial Inc. Second Quarter 2023 25


H. Investments

Total general fund invested assets of $165.8 billion as at June 30, 2023, were down $3.0 billion from December 31, 2022. The decrease was primarily due to unfavourable impacts from foreign exchange translation partially offset by increases in net fair value from declining interest rates. Our general fund invested assets are well-diversified across investment types, geographies and sectors with the majority of our portfolio invested in high quality fixed income assets.

The following table sets out the composition of our general fund invested assets:(1)


	June 30, 2023		December 31, 2022
($ millions)	Carrying value	% of Total carrying value		Carrying value	% of Total carrying value
Cash, cash equivalents and short-term securities	10,348	6%		11,219	7%
Debt securities	72,469	44%		75,902	45%
Equity securities	7,187	4%		7,148	4%
Mortgages and loans	52,338	32%		51,253	30%
Derivative assets	2,178	1%		2,095	1%
Other invested assets	11,296	7%		11,070	7%



Investment properties	10,001	6%		10,102	6%

Total invested assets	165,817	100%		168,789	100%

(1)The values and ratios presented are based on the fair value of the respective asset categories. Generally, the carrying values for invested assets are equal to their fair values. For invested assets supporting insurance contracts, in the event of default, if the amounts recovered are insufficient to satisfy the related insurance contract liability cash flows that the assets are intended to support, credit exposure may be greater than the carrying value of the assets.

1. Debt Securities

The debt securities portfolio is actively managed through a regular program of purchases and sales aimed at optimizing yield, quality, and liquidity, while ensuring that it remains well-diversified and duration-matched to insurance contract liabilities. As at June 30, 2023, with the exception of certain countries where we have business operations, including Canada, the United States and the Philippines, our exposure to debt securities from any single country did not exceed 1% of total invested assets.

Debt Securities by Geography

The carrying value of our debt securities by geographic location is presented in the following table.

Total debt securities	58,706	13,763	72,469	100%	59,357	16,545	75,902	100%

Our gross unrealized losses as at June 30, 2023 for fair value through profit or loss ("FVTPL") and FVOCI debt securities were $7,550 million and
$879 million, respectively (December 31, 2022 - $9,384 million and $1,521 million, respectively). The decrease in gross unrealized losses was largely due to declining long-term interest rates and the narrowing of credit spreads.

Debt Securities by Credit Rating

Debt securities with a credit rating of "A" or higher represented 72% of the total debt securities as at June 30, 2023 (December 31, 2022 - 72%). Debt securities with a credit rating of "BBB" or higher represented 99% of total debt securities as at June 30, 2023, (December 31, 2022 - 99%).

2. Mortgages and Loans

Our mortgage portfolio consisted almost entirely of first mortgages and our loan portfolio consisted of private placement loans. Changes to fair value estimates for loans was implemented on January 1, 2023. For additional details, refer to Note 2 in the Interim Consolidated Financial Statements for the period ended June 30, 2023.

Mortgages and Loans by Geography

(1)The geographic location for mortgages is based on the location of the property and for loans it is based on the country of the creditor's parent.

Mortgage Portfolio

As at June 30, 2023, we held $14.4 billion of mortgages (December 31, 2022 - $14.4 billion). Our mortgage portfolio consists entirely of commercial mortgages, as presented in the following table.


	June 30, 2023			December 31, 2022
($ millions)	Insured	Uninsured	Total	Insured	Uninsured	Total
Mortgages:
Retail	—	2,698	2,698	—	2,819	2,819
Office	—	2,836	2,836	—	3,014	3,014

% of Total mortgages	29%	71%	100%	28%	72%	100%

Our mortgage portfolio consists entirely of commercial mortgages, including retail, office, multi-family, and industrial properties. As at
June 30, 2023, 35% of our commercial mortgage portfolio consisted of multi-family residential mortgages; there are no single-family residential mortgages. Our uninsured commercial portfolio had a weighted average loan-to-value ratio of approximately 52% as at June 30, 2023 (December 31, 2022 - 53%). While we generally limit the maximum loan-to-value ratio to 75% at issuance, we may invest in mortgages with a higher loan-to-value ratio in Canada if the mortgage is insured by the Canada Mortgage and Housing Corporation ("CMHC"). The estimated weighted average debt service coverage for our uninsured commercial portfolio is 1.71 times. Of the $3.9 billion of multi-family residential mortgages in the Canadian commercial mortgage portfolio, 93% were insured by the CMHC.

As at June 30, 2023, we held $38.0 billion of loans (December 31, 2022 - $36.8 billion). Private placement loans provide diversification by type of loan, industry segment and borrower credit quality. The private placement loan portfolio consists of senior secured and unsecured loans to large- and mid-market corporate borrowers, securitized lease/loan obligations secured by a variety of assets, and project finance loans in sectors such as power and infrastructure.

As at June 30, 2023, our impaired mortgages and loans, net of allowances for losses, were $10 million (December 31, 2022 - $47 million).

3. Derivatives

The values associated with our derivative instruments are presented in the following table. Notional amounts serve as the basis for payments calculated under derivatives contracts and are generally not exchanged.


($ millions)	June 30, 2023	December 31, 2022
Net fair value asset (liability)	550	(256)
Total notional amount	68,413	69,768
Credit equivalent amount(1)	1,486	1,173
Risk-weighted credit equivalent amount(1)	34	26

(1)Amounts presented are net of collateral received.

The net fair value of derivatives was an asset of $550 million as at June 30, 2023 (December 31, 2022 - liability of $256 million). The increase in net fair value was driven by an increase in foreign exchange contracts due to the strengthening of Canadian dollar against U.S. dollar, increase in interest rate contracts driven by downward movement in yield curves and swap spread differentials between the U.S. and Canadian dollar.

MANAGEMENT'S DISCUSSION AND ANALYSIS Sun Life Financial Inc. Second Quarter 2023 27

The total notional amount of our derivatives decreased to $68.4 billion as at June 30, 2023 (December 31, 2022 - $69.8 billion). The change in notional amount is mainly attributable to a decrease in equity contracts for the replication of equity exposure.

4. Investment Properties

As at June 30, 2023, we held $10.0 billion of investment properties (December 31, 2022 - $10.1 billion). The decrease in our investment property portfolio is predominantly driven by a decline in market values in the office sector, partially offset by net purchases.

For additional information, refer to Note 2 in our Interim Consolidated Financial Statements for the period ended June 30, 2023.

28 Sun Life Financial Inc. Second Quarter 2023 MANAGEMENT'S DISCUSSION AND ANALYSIS


I. Risk Management

This section includes our disclosure on market risks and should be read in conjunction with our unaudited Interim Consolidated Financial Statements

for the quarter ended June 30, 2023.

We have established a Risk Management Framework to assist in identifying, measuring, managing, monitoring and reporting risks. The Risk

Management Framework covers all risks and these have been grouped into six major categories: market, insurance, credit, business and strategic,

operational and liquidity risks. Risk appetite limits are established for equity, interest rate, credit spread, real estate and foreign currency risks. Through our enterprise risk management processes, we oversee the various risk factors identified in the Risk Management Framework and provide reports to senior management and to the Board Committees at least quarterly. Our enterprise risk management processes and risk factors are described in our 2022 Annual MD&A and AIF.

On adoption of IFRS 17 and IFRS 9, we have updated the descriptions of risk factors related to equity, interest rates, credit and swap spreads, and real estate. For more information about the adoption of IFRS 17 and IFRS 9, see Note 2 of the Interim Consolidated Financial Statements for the period ended June 30, 2023.

When referring to segregated funds in this section, it is inclusive of segregated fund guarantees, variable annuities and investment products and includes Run-off reinsurance in Corporate.

Equity Risk

Equity risk is the potential for financial loss arising from declines or volatility in equity market prices. We are exposed to equity risk from a number of sources. A portion of our exposure to equity risk arises in connection with benefit guarantees on segregated fund products, some participating insurance contracts, some adjustable insurance contracts, and some universal life contracts. These benefit guarantees may be triggered upon death, maturity, withdrawal or annuitization. The cost of providing these guarantees is uncertain and depends upon a number of factors, including general capital market conditions, our hedging strategies, policyholder behaviour and mortality experience, each of which may result in negative impacts on net income, the contractual service margin, and capital.

We generate revenue in our asset management businesses and from certain insurance and annuity contracts where fees are levied on account balances that are affected directly by equity market levels. Accordingly, we have further exposure to equity risk as adverse fluctuations in the market value of such assets will result in corresponding adverse impacts on revenue, income, and the contractual service margin. In addition, declining and volatile equity markets may have a negative impact on sales and redemptions (surrenders) in these businesses, and this may result in further adverse impacts on net income, the contractual service margin, and capital.

We also have direct exposure to equity markets from the investments supporting other general account liabilities, surplus, and employee benefit plans. These exposures fall within our risk-taking philosophy and appetite, and are therefore generally not hedged.


Interest Rate and Spread Risk Interest rate and spread risk includes the potential for financial loss arising from changes in the value of insurance and investment contract liabilities and financial assets due to changes or volatility in interest rates or spreads. In practice, when asset cash flows and the policy obligations they support are not matched, this may result in the need to either sell assets to meet policy payments and expenses or reinvest excess asset cash flows in unfavourable interest rate or credit spread environments. This risk is managed in our asset-liability management program. Details of the asset-liability management program are discussed under the heading "Market Risk Management Governance and Control" in section J - Risk Management in our 2022 Annual MD&A. Our primary exposure to interest rate and spread risk arises from insurance and investment contracts that contain guarantees in the form of minimum crediting rates, maximum premium rates, settlement options, guaranteed annuitization options and minimum benefits. If investment returns fall below guaranteed levels, we may be required to increase liabilities or capital in respect of these contracts. The guarantees attached to these products may be applicable to both past premiums collected and future premiums not yet received. Segregated fund contracts provide benefit guarantees that are linked to underlying fund performance and may be triggered upon death, maturity, withdrawal or annuitization. We are also exposed to interest rate risk through guaranteed annuitization options included primarily in retirement contracts and pension plans. These embedded options give policyholders the right to convert their investment into a pension on a guaranteed basis, thereby exposing us to declining long-term interest rates as the annuity guarantee rates come into effect. The cost of providing these guarantees is uncertain and depends upon a number of factors including the level and concentration of the guarantees relative to prevailing interest rates, credit spreads, non-fixed income returns, and policyholder behaviour. Exposure to guarantees is managed within our risk appetite limits through our asset-liability management program, which may include the use of hedging strategies utilizing interest rate derivatives such as interest rate floors, swaps, futures and swaptions. The impact of these guarantees on net income, contractual service margin and capital are included in the disclosed market risk sensitivities. Declines in interest rates or narrowing spreads can result in compression of the net spread between interest earned on investments and interest credited to policyholders. Declines in interest rates or narrowing spreads can also result in increased asset calls, mortgage prepayments, and net reinvestment of positive cash flows at lower yields, and therefore adversely impact our profitability and financial position. Negative interest rates may additionally result in losses on our cash and short-term deposits and low or negative returns on our fixed income assets impacting our profitability. In contrast, increases in interest rates or a widening of credit spreads can reduce market values of fixed income assets, which may lead to lower capital or losses in the event of the liquidation of assets prior to maturity.

MANAGEMENT'S DISCUSSION AND ANALYSIS Sun Life Financial Inc. Second Quarter 2023 29


Significant changes or volatility in interest rates or spreads could have a negative impact on sales of certain insurance and annuity products, and adversely impact the expected pattern of redemptions (surrenders) on existing policies. Increases in interest rates or widening credit spreads may increase the risk that policyholders will surrender their contracts, potentially forcing us to liquidate assets at a loss. While we have established hedging programs in place and our insurance and annuity products often contain surrender mitigation features, these may not be sufficient to fully offset the adverse impact of changes in interest rates or spreads.


We also have direct exposure to interest rates and spreads from investments supporting other general account liabilities, surplus and employee benefit plans. Lower interest rates or a narrowing of spreads will result in reduced investment income on new fixed income asset purchases. Conversely, higher interest rates or wider spreads will reduce the value of our existing assets. These exposures fall within our risk-taking philosophy and appetite and are therefore generally not hedged.

A sustained low interest rate environment may adversely impact our net income, contractual service margin, capital, and our ability to implement our business strategy and plans in several ways, including:

•Lower sales of certain insurance and wealth products, which can in turn put pressure on our operating expense levels;

•Shifts in the expected pattern of redemptions (surrenders) on existing policies;

•Higher losses on new business;

•Reduced return on new fixed income asset purchases, and higher hedging costs;

•The impact of consequent changes in assumptions used to measure insurance contracts;

•Impairment of goodwill; and

•Valuation allowances against our deferred tax assets.

Real Estate Risk

Real estate risk is the potential for financial loss arising from fluctuations in the value of, or future cash flows from, our investments in real estate. We are exposed to real estate risk and may experience financial losses resulting from the direct ownership of real estate investments or indirectly through fixed income investments secured by real estate property, leasehold interests, ground rents, and purchase and leaseback transactions. Real estate price risk may arise from external market conditions, inadequate property analysis, inadequate insurance coverage, inappropriate real estate appraisals, or from environmental risk exposures. We hold real estate investments that support general account liabilities and surplus, and fluctuations in value will affect our net income, contractual service margin, and capital. A material and sustained increase in interest rates may lead to deterioration in real estate values.


i.Market Risk Sensitivities


We use a variety of methods and measures to manage and quantify our market risk exposures. These include duration and key rate duration management, convexity measures, cash flow gap analysis, scenario testing, and sensitivity testing of earnings and regulatory capital ratios. The measurement of liabilities and assets are affected by the level of equity market performance, interest rates, credit and swap spreads and other market risk variables. The following sections set out the estimated immediate impact on, or sensitivity of, our net income(1), contractual service margin, OCI and SLF Inc.'s LICAT ratio to certain instantaneous changes in market variables as at June 30, 2023 and December 31, 2022(2).



The estimated sensitivities in the tables below reflect the impact of market movements on insurance contracts and investment contracts, assets backing insurance contracts, assets backing investment contracts, assets backing the surplus segment, and seed investments in our asset management subsidiaries. Net income sensitivities to equity and real estate market movements are driven primarily by changes in the value of investments backing general account liabilities and surplus. Net income sensitivities to interest rates and spreads are driven by the net impact on liabilities and the assets backing them. Lower interest rates or a narrowing of spreads will result in increased liabilities for insurance contracts, offset by increased values of the assets backing general account liabilities. Higher interest rates or a widening of spreads will result in decreased liabilities for insurance contracts, offset by decreased values of the assets backing general account liabilities. Further detail on the impact of changes or volatility in market prices on assets and liabilities is provided under the headings "Equity Risk", "Interest Rate and Spread Risk", and "Real Estate Risk" above. OCI sensitivities are impacted by changes in the market value of assets classified as FVOCI. The market value of FVOCI fixed income assets, which are held primarily in our surplus and investment contract segments, increases with lower interest rates or a narrowing of spreads, and decreases with higher interest rates or a widening of spreads. Refer to Additional Cautionary Language and Key Assumptions Related to Sensitivities in this section for important additional information regarding these estimates.

(1)Net income in section I - Risk Management in this document refers to common shareholders' net income.

(2)Effective January 1, 2023, we adopted IFRS 17 and IFRS 9, and certain financial assets were reclassified between measurement categories as permitted. December 31, 2022 amounts provided in the sensitivities in section I - Risk Management of this document have been adjusted to reflect these
January 1, 2023 reclassifications. See Note 2 of the Interim Consolidated Financial Statements for the period ended June 30, 2023 for further details on the reclassifications.

(1)Effective January 1, 2023, we adopted IFRS 17 and IFRS 9, and certain financial assets were reclassified between measurement categories as permitted. December 31, 2022 amounts provided in the sensitivities in section I - Risk Management of this document have been adjusted to reflect these
January 1, 2023 reclassifications. See Note 2 of the Interim Consolidated Financial Statements for the period ended June 30, 2023 for further details on the reclassifications.

(2)Represents the respective change across all equity markets as at June 30, 2023 and December 31, 2022. Assumes that actual equity exposures consistently and precisely track the broader equity markets. Since in actual practice equity-related exposures differ from broad market indices (due to the impact of active management, basis risk, and other factors), realized sensitivities may differ significantly from those illustrated above. Sensitivities include the impact of re-balancing equity hedges for hedging programs at 2% intervals (for 10% changes in equity markets) and at 5% intervals (for 25% changes in equity markets).

(3)The market risk sensitivities include the estimated impact of our hedging programs in effect as at June 30, 2023 and December 31, 2022, and include new business added and product changes implemented prior to such dates.

(4)Net income, CSM and OCI sensitivities have been rounded in increments of $25 million. The sensitivities exclude the market impacts on the income from our joint ventures and associates, which we account for on an equity basis.

(5)The LICAT sensitivities illustrate the impact on SLF Inc. as at June 30, 2023 and December 31, 2022. LICAT ratios are rounded in increments of 0.5%.

2.Interest Rate Sensitivities

The following table sets out the estimated immediate impact on, or sensitivity of, our net income, contractual service margin, OCI and SLF Inc.'s LICAT ratio to certain instantaneous changes in interest rates as at June 30, 2023 and December 31, 2022(1).


($ millions, unless otherwise noted)	As at June 30, 2023				As at December 31, 2022(1)
Change in Interest Rates(2)(3)(4)	50 basis point decrease		50 basis point increase		50 basis point decrease		50 basis point increase
Potential impact on net income (after-tax)		—		25		(100)		75
Potential impact on CSM (pre-tax)		125		(125)		125		(150)
Potential impact on OCI		225		(225)		225		(225)
Potential impact on LICAT ratio(5)	2.0% point increase		2.0% point decrease		1.5% point increase		2.5% point decrease

(2)Interest rate sensitivities assume a parallel shift in assumed interest rates across the entire yield curve as at June 30, 2023 and December 31, 2022 with no change to the ultimate risk-free rate. Variations in realized yields based on factors such as different terms to maturity and geographies may result in realized sensitivities being significantly different from those illustrated above. Sensitivities include the impact of re-balancing interest rate hedges for hedging programs at 10 basis point intervals (for 50 basis point changes in interest rates).

(5)The LICAT sensitivities illustrate the impact on SLF Inc. as at June 30, 2023 and December 31, 2022. The sensitivities reflect the worst scenario as at June 30, 2023 and assume that a scenario switch does not occur in the quarter. LICAT ratios are rounded in increments of 0.5%.

The above sensitivities were determined using a 50 basis point change in interest rates and a 10% and 25% changes in our equity markets because we believe that these market shocks were reasonably possible as at June 30, 2023. Significant changes in market variables may result in other than proportionate impacts on our sensitivities.

3. Credit Spread and Swap Sensitivities Credit spread sensitivities reflect the impact of changes in credit spreads on our asset and liability values (including provincial government bonds, corporate bonds, and other fixed income assets). Swap spread sensitivities reflect the impact of changes in swap spreads on swap-based derivative positions and liability values.

The following tables set out the estimated immediate impact on, or sensitivity of, our net income, contractual service margin, OCI and SLF Inc.'s LICAT ratio to certain instantaneous changes in credit spreads and our net income, contractual service margin, and OCI to certain changes in swap spreads as at June 30, 2023 and December 31, 2022(1).


($ millions, unless otherwise noted)	As at June 30, 2023				As at December 31, 2022(1)
Change in Credit Spreads(2)(3)	50 basis point decrease		50 basis point increase		50 basis point decrease		50 basis point increase
Potential impact on net income (after-tax)		75		(100)		50		(50)
Potential impact on CSM (pre-tax)		100		(150)		75		(100)
Potential impact on OCI		200		(200)		200		(200)
Potential impact on LICAT ratio(4)	1.5% point increase		2.0% point decrease		1.0% point increase		2.0% point decrease

(2)The credit spread sensitivities assume a parallel shift in the indicated spreads across the entire term structure with no change to the ultimate liquidity premium. The sensitivities reflect a floor of zero on credit spreads where the spreads are not currently negative. Variations in realized spread changes based on different terms to maturity, geographies, asset classes and derivative types, underlying interest rate movements, and ratings may result in realized sensitivities being significantly different from those provided above.

(3)Net income, CSM, and OCI sensitivities have been rounded in increments of $25 million.

(4)The LICAT sensitivities illustrate the impact on SLF Inc. as at June 30, 2023 and December 31, 2022. The sensitivities reflect the worst scenario as of June 30, 2023 and assume that a scenario switch does not occur in the quarter. LICAT ratios are rounded in increments of 0.5%.

5.Segregated Funds Risk & Hedging

Certain segregated fund products provide benefit guarantees, which are linked to underlying fund performance and may be triggered upon death, maturity, withdrawal or annuitization. The cost of providing these guarantees is uncertain and depends upon a number of factors including general capital market conditions, our hedging activities, policyholder behaviour and mortality experience, each of which may result in negative impacts on net income, the contractual service margin and capital.

Our hedging programs use derivative instruments and fixed income assets to mitigate the interest rate and equity market exposure of our segregated fund contracts. As at June 30, 2023, over 90% of our segregated fund contracts, as measured by fund values, were included in a hedging program. While a large percentage of contracts are included in the hedging program, not all of our market risk exposure related to these contracts is hedged. For those segregated fund contracts included in the hedging program, we generally hedge the value of expected future net claims costs and associated risk adjustments for non-financial risk.

Our hedging strategy is applied both at the line of business or product level and at the total company level using a combination of hedging techniques such as re-balancing of short-dated interest rate and equity derivative contracts and longer-dated put options. We actively monitor our overall market exposure and may implement tactical hedge overlay strategies in order to align sensitivities with risk management objectives.

The impact of segregated fund guarantees and associated hedging programs on net income, contractual service margin and capital are included in the disclosed market risk sensitivities.


6. Additional Cautionary Language and Key Assumptions Related to Sensitivities
Our market risk sensitivities are measures of our estimated change in net income, OCI,	CSM and LICAT ratio	for changes in market risk variables
described above, based on market risk variables and business in force as at the reporting date. These sensitivities are calculated independently for each risk factor, generally assuming that all other risk variables stay constant. The sensitivities do not take into account indirect effects such as potential impacts on goodwill impairment or valuation allowances on deferred tax assets.

We have provided measures of our net income sensitivity to instantaneous changes in equity markets, interest rates, credit spreads, swap spreads, real estate price levels, and capital sensitivities to changes in equity price levels, interest rates and credit spreads. The LICAT ratio and CSM sensitivities are non-IFRS financial measures, and for additional information, see section N - Non-IFRS Financial Measures in this document. The cautionary language which appears in this section is applicable to all net income, CSM, OCI and LICAT ratio sensitivities.


Actual results can differ materially from these estimates for a variety of reasons, including differences in the pattern or distribution of the market shocks, the interaction between these risk factors, model error, or changes in other assumptions such as business mix, effective tax rates, policyholder behaviour, currency exchange rates and other market variables relative to those underlying the calculation of these sensitivities. The extent to which actual results may differ from the indicative ranges will generally increase with larger movements in risk variables. Our sensitivities as at December 31, 2022(1) have been included for comparative purposes only.

As these market risk sensitivities reflect an instantaneous impact on net income, CSM, OCI and SLF Inc.'s LICAT ratio, they do not include impacts over time such as the effect on fee income in our asset management businesses.


The sensitivities reflect the composition of our assets and liabilities as at June 30, 2023 and December 31, 2022(1), respectively. Changes in these positions due to new sales or maturities, asset purchases/sales, or other management actions could result in material changes to these reported sensitivities. In particular, these sensitivities reflect the expected impact of hedging activities based on the hedging programs in place as at the June 30 and December 31(1) calculation dates. The actual impact of hedging activity can differ materially from that assumed in the estimated sensitivities due to ongoing hedge re-balancing activities, changes in the scale or scope of hedging activities, changes in the cost or general availability of hedging instruments, basis risk (i.e., the risk that hedges do not exactly replicate the underlying portfolio experience), model risk, and other operational risks in the ongoing management of the hedge programs or the potential failure of hedge counterparties to perform in accordance with expectations.

MANAGEMENT'S DISCUSSION AND ANALYSIS Sun Life Financial Inc. Second Quarter 2023 33


Our hedging programs may themselves expose us to other risks, including basis risk, volatility risk, and increased levels of derivative counterparty credit risk, liquidity risk, model risk and other operational risks. These factors may adversely impact the net effectiveness, costs, and financial viability of maintaining these hedging programs and therefore adversely impact our profitability and financial position. While our hedging programs are intended to mitigate these effects (e.g., hedge counterparty credit risk is managed by maintaining broad diversification, dealing primarily with highly-rated counterparties, and transacting through over-the-counter ("OTC") contracts cleared through central clearing houses, exchange-traded contracts or bilateral OTC contracts negotiated directly between counterparties that include credit support annexes), residual risk, potential reported earnings and capital volatility remain. The sensitivities are based on methods and assumptions in effect as at June 30, 2023 and December 31, 2022(1), as applicable. Changes in the regulatory environment, assumptions or methods used to measure assets and liabilities after those dates could result in material changes to the estimated sensitivities. Changes in market risk variables in excess of the changes illustrated may result in other than proportionate impacts.

The sensitivities reflect the CSM as at June 30, 2023 and December 31, 2022(1). For insurance contracts measured using the VFA, where the change in the effect of the time value of money and financial risk not arising from the underlying items adjusts the CSM, changes in the CSM balance will affect the sensitivity of income to changes in market risk variables.

Our LICAT sensitivities may be non-linear and can change due to the interrelationship between market rates and spreads, actuarial assumptions and our LICAT calculations.


For the reasons outlined above, our sensitivities should only be viewed as indicative estimates of the underlying sensitivities of each factor under
these specialized assumptions, and should not be viewed as predictors of our future income, OCI,	CSM or capital.	Given the nature of these
calculations, we cannot provide assurance that actual impacts will be consistent with the estimates provided.

Information related to market risk sensitivities should be read in conjunction with the information contained in section M - Accounting and Control Matters - 1 - Critical Accounting Policies and Estimates in the 2022 Annual MD&A. Additional information on market risk can be found in Note 2 of the 2022 Annual Consolidated Financial Statements and the Risk Factors section in the 2022 AIF.

They are the principal source of funds to pay for policyholder claims and benefits, commissions, operating expenses, and the purchase of investments. Cash flows used in investing activities primarily include transactions related to associates, joint ventures and acquisitions. Cash flows provided by and used in financing activities largely reflect capital transactions including payments of dividends, the issuance and repurchase of shares, as well as the issuance and retirement of debt instruments and preferred shares.

Q2'23 cash flows provided by financing activities decreased year-over-year due to higher borrowing from credit facilities in the prior year.

First Quarter 2023

Underlying net income of $895 million increased $175 million or 24%, driven by:

•Wealth & asset management down $11 million: Lower fee-based earnings in MFS, Canada, and Asia, reflecting equity market declines, largely offset by an increase in investment income driven by higher volumes and yields.

•Group - Health & Protection up $180 million: Strong performance including premium growth, improved disability in Canada and the U.S., strong medical stop-loss margins, and improved U.S. mortality. DentaQuest results also contributed to the increase.

•Individual - Protection up $42 million: Higher premiums reflecting good sales momentum during the past year, and improved mortality in Asia.

•Corporate Support & other $(36) million increased net loss: Higher operating expenses including long-term incentive compensation and IFRS 17 project spend, as well as an increase in debt financing costs.

•Higher investment income reflecting an increase in realized gains from surplus assets and net interest income from higher rates.

36 Sun Life Financial Inc. Second Quarter 2023 MANAGEMENT'S DISCUSSION AND ANALYSIS

Reported net income of $806 million increased $141 million or 21%, driven by the increase in underlying net income and gain on the sale of the sponsored markets business in Canada, partially offset by market-related impacts, and DentaQuest integration and SLC Management acquisition-related costs.

Fourth Quarter 2022(1)

Reported net income of $951 million decreased $127 million or 12%, primarily reflecting unfavourable market-related impacts and DentaQuest integration costs, partially offset by the impact of the Canada Tax Rate Change, fair value changes on MFS' share-based payment awards and ACMA. Prior year reported net income included a gain on the initial public offering ("IPO") of our India asset management joint venture partially offset by an increase to SLC Management's acquisition-related liabilities. Underlying net income of $990 million increased $92 million or 10%, driven by business growth and experience in protection and health and contribution from the DentaQuest acquisition. This was partially offset by lower wealth and asset management earnings reflecting declines in global equity markets, and a higher effective tax rate compared to prior year.

Third Quarter 2022(1)

Reported net income of $466 million decreased $553 million or 54% from prior year, primarily reflecting unfavourable market-related impacts, a

$170 million charge related to the sale of Sun Life UK, less favourable ACMA impacts, and an increase in SLC Management's acquisition-related

liabilities, partially offset by fair value changes on MFS' share-based payment awards. Underlying net income of $949 million increased $47 million or 5%, driven by business growth and experience in protection and health including a strong contribution from the DentaQuest acquisition. This was partially offset by lower fee-based income in wealth and asset management, mainly driven by declines in global equity markets.

Second Quarter 2022(1)

Q2'22 reported net income of $785 million decreased $115 million or 13%, reflecting unfavourable market-related impacts and DentaQuest acquisition costs, partially offset by fair value changes on MFS' share-based payment awards and a gain on the sale-leaseback of our Wellesley office in the U.S. Underlying net income of $892 million was up slightly driven by business growth, new business gains, contribution from the DentaQuest acquisition, and lower incentive compensation expenses. This was largely offset by Asset Management results reflecting a decline in global equity markets driving lower average net assets, lower available-for-sale gains and morbidity experience in the U.S. Foreign exchange translation led to an increase of $16 million and $12 million in reported net income and underlying net income, respectively.

First Quarter 2022(1)

Q1'22 reported net income of $858 million decreased $79 million or 8%, driven by less favourable market-related impacts, partially offset by a Q1'21 restructuring charge and lower fair value changes on MFS' share-based payment awards. Underlying net income of $843 million was down slightly, driven by broad-based business growth, favourable expense experience and investment gains, offset by unfavourable mortality and morbidity experience, and lower AFS gains.

Fourth Quarter 2021(1)

Q4'21 reported net income of $1,078 million increased $334 million or 45% compared to the prior year, driven by a $297 million gain on the IPO of our India asset management joint venture and an increase in the value of our real estate investments, partially offset by a

$153 million increase in SLC Management's acquisition-related liabilities. Underlying net income of $898 million increased $36 million or 4%, driven by broad-based business growth across our pillars, with particular strength in asset management and wealth. Underlying net income also benefited from a lower effective tax rate in the quarter, largely offset by $113 million of ongoing COVID-19-related mortality and morbidity experience. Foreign exchange translation led to a decline of $33 million in reported net income and $22 million in underlying net income.

Third Quarter 2021(1)

Q3'21 reported net income of $1,019 million increased $269 million or 36% compared to the prior year, driven by favourable market-related impacts from changes in the fair value of investment properties, and ACMA, partially offset by a par allocation adjustment. Underlying net income of

$902 million increased by $60 million or 7%, driven by business growth, favourable credit experience and higher tax-exempt investment income. This was partially offset by morbidity and expense experience, and the unfavourable impacts of foreign exchange translation. Mortality experience was elevated in the U.S. and Asia, but relatively in line with the prior year. During the Q3'21, the impacts of foreign exchange translation led to a decline of $41 million in reported net income and $36 million in underlying net income.

L. Changes in Accounting Policies

On January 1, 2023 we adopted IFRS 17 Insurance Contracts and IFRS 9 Financial Instruments, detailed below. We have also adopted several amended IFRS standards in the current year, which had no material impact on our Consolidated Financial Statements. For additional information, refer to Note 2 in our Interim Consolidated Financial Statements for the period ended June 30, 2023.

1. Changes in Accounting Policies
We have included in this section a summary of changes in accounting policies.

1.A. Adoption of IFRS 17 Insurance Contracts and IFRS 9 Financial Instruments

In May 2017, the IASB issued IFRS 17 Insurance Contracts ("IFRS 17"), with an amendment issued in June 2020 to defer the effective date of IFRS 17 to annual periods beginning on or after January 1, 2023. This standard is to be applied using a retrospective approach, with at least one year of comparative results provided. If retrospective application to a group of insurance contracts is impracticable, a modified retrospective or fair value approach may be used. IFRS 17 replaces IFRS 4 Insurance Contracts ("IFRS 4") and impacts how we recognize, measure, present, and disclose our insurance contracts in our Consolidated Financial Statements.

IFRS 17 and IFRS 9 Financial Instruments ("IFRS 9") were effective for us beginning January 1, 2023. IFRS 9 includes guidance on the classification and measurement of financial instruments, impairment of financial assets and hedge accounting, and does not require restatement of comparative periods. IFRS 9 replaces IAS 39 Financial Instruments: Recognition and Measurement ("IAS 39"). We are permitted, under IFRS 17, to present comparative information on financial assets as if IFRS 9 were applicable during the comparative period ("classification overlay"). We have elected to apply the classification overlay to our financial assets and their comparative period results as if IFRS 9 had been effective since January 1, 2022. Certain comparative period information will continue to be presented in accordance with our previous accounting policies.

For initial measurement of insurance contracts at the transition date of January 1, 2022, we have elected to use the fair value approach for all groups for which the retrospective approach is impracticable. For more information on the application of the fair value approach at transition, see the heading "Fair Value Measurement" in Note 2.A.i in our Interim Consolidated Financial Statements for the period ended June 30, 2023.

IFRS 17 establishes principles for the recognition, measurement, presentation, and disclosure of insurance contracts. The key principles of IFRS 17 are as follows:

•Insurance contracts are those under which an entity accepts significant insurance risk from another party ("policyholder") by agreeing to compensate the policyholder if a specified uncertain future event ("insured event") adversely affects the policyholder.

•Insurance contracts issued and reinsurance contracts held are divided into groups that will be separately recognized and measured.

•Groups of insurance contracts are recognized and measured as the total of the following measurement components: a) the present value of future cash flows; b) a risk adjustment for non-financial risk ("RA"); and c) the Contractual Service Margin ("CSM"), an amount that represents the unearned profit of the group of contracts. These measurement components apply to groups of insurance contracts measured using the general measurement approach ("GMA") and the variable fee approach ("VFA"). The VFA applies to insurance contracts issued with direct participation features, which are substantially investment-related service contracts under which the policyholder is promised an investment return based on underlying items, such as segregated funds and certain participating insurance contracts. For short duration contracts, such as most of our group life and health business, a simplified measurement approach (the premium allocation approach ("PAA") is applied. Under the PAA, insurance contracts are measured based on unearned profits and do not include a CSM.

•The profit from a group of insurance contracts is recognized into income over the period that insurance contract services are provided and as the non-financial risks related to providing the insurance contracts diminish.

•Insurance revenue, insurance service expenses and insurance finance income or expenses are presented separately.

Significant Differences between IFRS 17 and IFRS 4

The following section describes the most significant differences between IFRS 17 and the accounting policies applied under IFRS 4.

Scope

There is no substantial change in IFRS 17 compared to IFRS 4 with regards to which contracts fall within the scope of the standard. However, we have updated the accounting policy for classification that was adopted on the transition to IFRS 4 in 2011 to ensure consistency with the IFRS 17 definition of insurance contracts.

Under IFRS 17, an insurance contract is defined as a contract under which the issuer accepts significant insurance risk from the policyholder by agreeing to compensate the policyholder if an insured event adversely affects the policyholder. In assessing whether "significant" insurance risk exists, certain contracts that were classified as insurance contracts under IFRS 4 were reclassified as investment contracts under IFRS 17. Such changes in classification were limited to certain deferred annuity products where the insurance risk is limited to the right to annuitize the maturity benefit, which fell short of the threshold for "significant" insurance risk.

Furthermore, IFRS 17 includes new requirements for the separation of distinct investment components and distinct goods or non-insurance service components of insurance contracts. At transition to IFRS 17, there were no distinct investment components and only immaterial distinct service components in our insurance contracts.

Unlike IFRS 4, IFRS 17 requires reinsurance contracts held to be measured separately from the underlying direct contracts. A reinsurance contract is an insurance contract issued by the reinsurer to compensate another entity for claims arising from one or more insurance contracts issued by that other entity ("underlying contracts").

38 Sun Life Financial Inc. Second Quarter 2023 MANAGEMENT'S DISCUSSION AND ANALYSIS

Only contracts that transfer insurance risk to the reinsurer are considered reinsurance contracts held from the ceding entity’s point of view. We have reinsurance treaties that transfer only non-insurance risks to the reinsurer, however these are not considered reinsurance contracts held in scope of IFRS 17, nor were they in scope of IFRS 4. Rather, they are insurance contracts purchased.

Reinsurance treaties that are part of the underlying items of participating insurance contracts (i.e., where all the cash flows of the reinsurance treaty are fully passed through to the participating insurance policyholders) are measured and reported separately.

Investment contracts with discretionary participation features ("DPF") are in scope of IFRS 17 and were in scope of IFRS 4. However, such contracts were reported with other investment contracts under IFRS 4, and are reported with insurance contracts under IFRS 17.

Measurement

The measurement of insurance contracts under IFRS 17 differs from the Canadian Asset Liability Method previously applied under IFRS 4. The most significant differences by measurement component are as follows:

Present value of future cash flows:

•The discount rates used to present value future cash flows under IFRS 17 are based on the characteristics of the insurance contracts. Under IFRS 4, the Canadian Asset Liability Method is used to determine actuarial liabilities based on the portfolio of assets currently supporting the insurance contract liabilities and reinvestment assumptions.

•Estimates under IFRS 17 include the current market view of the cost of financial guarantees, which requires a valuation consistent with market option prices. Under IFRS 4, the cost of financial guarantees is based on the amount required to fulfill the obligation but not directly linked to market option prices.

•Expense cash flows under IFRS 17 are limited to those directly attributable to fulfillment of the obligations under insurance contracts.

•Future income taxes are excluded from future cash flows under IFRS 17.

Risk adjustment for non-financial risk:

•Measures the compensation required for uncertainty related to non-financial risk, such as mortality, morbidity, surrender and expenses under IFRS 17.

•Provisions for uncertainty related to financial risk are implicitly included in the present value of future cash flows under IFRS 17.

•No amount is provided for asset-liability mismatch risk under IFRS 17.

•Under IFRS 4, amounts provided for the risks listed above are reflected in a provision for adverse deviations included in insurance contract liabilities.

CSM:

•This is a new component of liabilities and necessitates the "grouping" of insurance contracts, which is not required under IFRS 4.

•The CSM represents unearned profits, as discussed above.

The measurement approaches under IFRS 17 and IFRS 4 are similar for insurance contracts measured using the PAA, such as our group life and health contracts. Differences arise mainly in the measurement of the liability for incurred claims ("LIC"), where the discount rate and risk adjustment for non-financial risk changes noted above apply.

Presentation

IFRS 17 requires that portfolios of insurance contracts that are in an asset position be presented separately from portfolios of insurance contracts that are in a liability position in the Consolidated Statements of Financial Position. Also, portfolios of insurance contracts issued must be presented separately from portfolios of reinsurance contracts held. Previously, insurance contracts issued were presented only as liabilities and reinsurance contracts held were presented only as assets. Certain balances, such as policy loans and outstanding and prepaid premiums, that were previously presented separately or included in Other assets and Other liabilities are now included in the assets or liabilities for insurance contracts issued or reinsurance contracts held.

The presentation of income from insurance contracts on the Consolidated Statements of Operations has changed significantly for IFRS 17. Prior to IFRS 17, insurance related income was presented separately in the lines Gross premiums, Ceded premiums, Gross claims and benefits paid, Reinsurance expenses (recoveries), Increase (decrease) in insurance contract liabilities, and Decrease (increase) in reinsurance assets. The line Operating expenses, commissions and premium taxes included all expenses, reflecting those from both insurance and non-insurance contracts.

Under IFRS 17, insurance-related income is presented in the Insurance service result section and the Insurance finance income (expenses) line in the Investment result section. Amounts are presented separately for insurance contracts issued and reinsurance contracts held. The Insurance service expenses line includes amounts previously reported as Gross claims and benefits paid, with the exclusion of repayments of investment components, which are amounts that are returned to policyholders under all circumstances. Directly attributable expenses are also presented as Insurance service expenses. Income or expense from reinsurance contracts held is now presented as one line, which includes an allocation of reinsurance premiums paid and amounts recovered from reinsurers.

For insurance contracts measured using the GMA or VFA, premiums are no longer reported as revenue or recognized in income when received. Insurance revenue in a reporting period is comprised of the portion of premiums that cover expected claims and directly attributable expenses in the period, as well as the release of RA and the amortization of CSM for the period. Insurance revenue excludes the portion of premiums that cover repayment of investment components.

Fee income excludes income from insurance contracts as any fees earned would be recognized in Insurance contract revenue. Similarly, the Operating expenses and commissions line excludes expenses that are directly attributable to issuing or fulfilling insurance contracts as these expenses, as well as premium taxes paid, are included in the Insurance service result section.

MANAGEMENT'S DISCUSSION AND ANALYSIS Sun Life Financial Inc. Second Quarter 2023 39

Revised accounting policies on adoption of IFRS 17

For more information about the revised accounting policies as a result of the adoption of IFRS 17 that differ from those included in our 2022 Annual Consolidated Financial Statements, refer to the heading "Revised Accounting Policies" in Note 2.A.i of our Interim Consolidated Financial Statements for the period ended June 30, 2023.

Impacts on our financial performance

We have highlighted in the following section certain impacts on our financial performance as a result of the differences between IFRS 17 and IFRS 4 described above:

•New business gains (unearned profits) are measured differently under IFRS 17, reflecting measurement differences on insurance contracts as discussed above. In addition, new business gains under IFRS 17 are deferred and recorded in the CSM and amortized into income as insurance contract services are provided. Losses on new business are also measured differently, but continue to be recognized in income immediately. Under IFRS 4, new business gains and losses were both recognized in income immediately.

•Discount rates used in calculating the present value of insurance contract liabilities are based on the characteristics of the insurance contracts rather than the assets supporting the liabilities. Amongst other differences, this results in changes in the timing of when investment-related income emerges.

•Under IFRS 17, changes related to financial risk (e.g. changes in the discount rate) continue to be recognized in income immediately, except for insurance contracts measured using the VFA, where the changes are recorded through the CSM. Assumption changes for non-financial risk, such as mortality, are reflected in the CSM and amortized into income as insurance contract services are provided. Under IFRS 4, assumption changes for both financial and non-financial risk variables were recognized in income immediately.

Significant Differences between IFRS 9 and IAS 39

The following section describes the most significant differences between IFRS 9 and the accounting policies applied under IAS 39.

Classification of financial assets and financial liabilities

IFRS 9 introduces three principal classification categories for financial assets. Financial assets are measured at initial recognition at fair value, and are classified as and subsequently measured at fair value through profit or loss ("FVTPL"), FVOCI or amortized cost based on our business model for managing the financial asset and the contractual cash flow characteristics of the asset.

IFRS 9 eliminates the previous IAS 39 categories of held-to-maturity ("HTM"), available-for-sale ("AFS"), and loans and receivable financial assets. Under IFRS 9, derivatives embedded in contracts where the host is a financial asset in scope of IFRS 9 are not separated. Instead, the hybrid financial instrument, as a whole, is assessed for classification.

IFRS 9 maintains the IAS 39 classification for financial liabilities. Under IFRS 9, financial liabilities are measured at either amortized cost or FVTPL.

Under IFRS 17, we elected to recognize all insurance finance income or expense in income rather than other comprehensive income. Consequently, to avoid an accounting mismatch, we are electing under IFRS 9 to classify most of our fixed income assets supporting insurance contracts as FVTPL.

Impairment of financial assets

IFRS 9 replaces the "incurred loss" model under IAS 39 with a forward-looking "expected credit loss" ("ECL") model. The new impairment model applies to financial assets measured at amortized cost, debt securities measured at FVOCI, mortgages and loans measured at FVOCI, lease receivables, account receivables, loan commitments and financial guarantees not measured at FVTPL. Credit losses are recognized earlier under IFRS 9 as compared previously under IAS 39. IFRS 9 introduces an impairment model for financial assets not measured at FVTPL. The model requires the recognition of an allowance for 12-month expected losses at the initial recognition of a financial asset, and the recognition of an allowance for lifetime expected losses if certain criteria are met.

Hedge accounting

IFRS 9 introduced a new hedge accounting model, but permits entities to continue applying hedge accounting requirements under IAS 39 instead of those under IFRS 9. We have elected to continue applying the hedge accounting requirements under IAS 39.

Revised accounting policies on adoption of IFRS 9

For more information about the revised accounting policies as a result of the adoption of IFRS 9 that differ from those included in our 2022 Annual Consolidated Financial Statements, refer to the heading "Policies applicable beginning January 1, 2023 (IFRS 9)" in Note 2.A.ii of our Interim Consolidated Financial Statements for the period ended June 30, 2023.

2. Critical Accounting Policies and Estimates

Our significant accounting and actuarial policies are described in Notes 2 and 6 of our Interim Consolidated Financial Statements for the period ended June 30, 2023. Management must make judgments involving assumptions and estimates, some of which may relate to matters that are inherently uncertain, under these policies. The estimates described below are considered particularly significant to understanding our financial performance. As part of our financial control and reporting, judgments involving assumptions and estimates are reviewed by the independent auditor and by other independent advisors on a periodic basis. Accounting policies requiring estimates are applied consistently in the determination of our financial results.

40 Sun Life Financial Inc. Second Quarter 2023 MANAGEMENT'S DISCUSSION AND ANALYSIS

Consolidated Financial Statements as well as the disclosures in this section of the interim MD&A provide additional context during the first year of adoption of IFRS 17 and IFRS 9. The majority of these disclosures would otherwise only be reported by us annually.

2.A Insurance Contracts Summary and Methods and Assumptions

Summary

We sell a variety of insurance contracts that include many forms of life, health and critical illness insurance sold to individuals and groups, annuities, and segregated fund products with guarantees. We hold reinsurance contracts that transfer mortality and other risks following internal guidelines.

Insurance contracts with direct participation features are products where investments are managed on behalf of policyholders, and investment returns less a variable fee are passed through to policyholders with the insurance benefits they receive. Insurance contracts with direct participation features are measured using the VFA, and include segregated funds, unit-linked contracts, variable universal life contracts, and most participating insurance contracts. Reinsurance contracts (both issued and held) cannot be measured using the VFA.

Insurance contracts without direct participation features are eligible to use the PAA if the coverage period is one year or less, or if the result of applying the PAA is not expected to be a materially different result than applying the GMA in each reporting period over the life of the contract. Insurance contracts eligible to use the PAA include most group life and health contracts and the associated reinsurance contracts held.

Other insurance contracts are measured using the GMA. This includes most individual life and health insurance contracts and annuities and the associated reinsurance contracts held.

For more information about insurance contracts issued and reinsurance contracts held, and Insurance contract liabilities for account of segregated fund holders, see Note 2, Note 7 and Note 12 of our Interim Consolidated Financial Statements for the period ended June 30, 2023.

Methods and Assumptions

General

A group of insurance contracts is measured as the total of FCF, which is the present value of future cash flows plus the risk adjustment for

non-financial risk, and, for groups measured using the GMA or VFA, the CSM. In measuring the present value of future cash flows, assumptions must be made about mortality and morbidity rates, lapse and other policyholder behaviour ("policyholder behaviour"), expenses and other factors over the life of our products, and the prevailing market view of the cost of financial risk in our products. Many of these assumptions relate to events that are anticipated to occur many years in the future. Assumptions require significant judgment and regular review and, where appropriate, revision.

The RA is the compensation we require for the uncertainty related to non-financial risk in the estimates of future cash flows. This compensation is measured by discounting cash flows from applying margins to the non-financial assumptions used in the estimate of future cash flows.

The CSM represents the unearned profit that will be recognized as insurance contract services are provided.

The methods and assumptions used in the measurement of insurance contracts are reviewed regularly and are subject to external actuarial peer review.

Present Value of Future Cash Flows

Assumptions for non-financial risk variables in the present value of future cash flows are intended to be current, neutral estimates of the expected outcome. The choice of assumptions takes into account current circumstances, past experience data from our own experience or from the industry, the relationship of past to expected future experience, anti-selection, the relationship among assumptions (including those for financial risk variables), and other relevant factors.

Assumptions for financial risk variables in the present value of future cash flows are based on current observable market prices, adjusted to account for differences between the financial risk embedded in our products and those in the corresponding observed market instrument. Where no relevant market instrument is available, we use the best information available.

Mortality

Mortality refers to the rates at which death occurs for defined groups of people. Mortality assumptions are generally based on the past five to ten years of experience. Our experience is combined with industry experience or experience from reinsurers where our own experience is insufficient to be statistically valid. Assumed mortality rates for life insurance and annuity contracts include assumptions about future mortality improvement based on recent trends in population mortality and our outlook for future trends.

Morbidity

Morbidity refers to the rate of being unhealthy or disabled and the rates of recovery therefrom. Most of our disability insurance is marketed on a group basis. We offer critical illness policies on an individual basis in Canada and Asia, long-term care on an individual basis in Canada, and medical stop-loss insurance is offered on a group basis in the U.S. In Canada, group morbidity assumptions are based on our five-year average experience, modified to reflect any emerging trend in recovery rates. For Canadian long-term care and critical illness insurance in Canada and Asia, assumptions are developed in collaboration with our reinsurers and are largely based on their experience. In the U.S., our experience is used for both medical stop-loss and disability assumptions, with some consideration of industry or reinsurer experience.

MANAGEMENT'S DISCUSSION AND ANALYSIS Sun Life Financial Inc. Second Quarter 2023 41

Policyholder Behaviour

Lapse or surrender

Policyholders may allow their policies to lapse prior to the end of the contractual coverage period by choosing not to continue to pay premiums or by surrendering their policy for the cash surrender value. Assumptions for lapse or surrender experience on life insurance are generally based on our five-year average experience. Lapse or surrender rates vary by plan, age at issue, method of premium payment, policy duration and financial risk variables.

Premium payment patterns

For universal life contracts, it is necessary to set assumptions about premium payment patterns. Studies prepared by industry or the actuarial profession are used for products where our experience is insufficient to be statistically valid. Premium payment patterns usually vary by plan, age at issue, method of premium payment, policy duration and financial risk variables.

Expense

Future expenses directly attributable to the fulfilment of our insurance contracts include the costs of premium collection, claims adjudication and processing, actuarial calculations, preparation and mailing of policy statements, and related overhead. Future expense assumptions are mainly based on our recent experience using an internal expense allocation methodology. Inflationary increases assumed in future expenses are based on long-term expectations.

Acquisition expenses directly attributable to portfolios of insurance contracts include the costs of selling, underwriting and issuing insurance contracts. For new insurance contracts measured using the GMA or VFA, actual or estimated directly attributable acquisition expenses are recognized in the initial measurement of the contract. If estimates are used, the difference between estimated and actual acquisition expenses adjusts the CSM when the group of insurance contracts is closed to new contracts.

Current Discount Rates

Current discount rates are used to discount estimates of future cash flows in determining the present value of future cash flows. Current discount rates reflect the time value of money, the characteristics of the cash flows, and the liquidity characteristics of the insurance contracts.

Current discount rates for cash flows that do not vary based on returns on underlying items

Cash flows that do not vary at all based on the returns on any underlying items are discounted at rates that reflect the timing and currency of cash flows and the liquidity characteristics of the insurance contracts.

The timing of cash flows is reflected by constructing a discount curve, so that each cash flow is discounted consistent with the timing of the cash flow. In constructing the discount curve, a portion is based on market information (the observable period) and beyond that period, the discount rates are estimated (the unobservable period). The observable period, which varies by currency, is the time period where information on risk-free interest rates is deep and liquid. In the unobservable period, risk-free rates are interpolated between the last observable point and an ultimate risk-free rate at year 70. The ultimate risk-free rate is estimated using historical averages.

The currency of cash flows is reflected by using different discount curves for different currencies.

Liquidity is reflected by adding a liquidity premium to risk-free discount rates that is consistent with the liquidity characteristics of the insurance contracts. The liquidity premium in the observable period is based on the liquidity premium on assets with similar liquidity characteristics, which is estimated from the spread inherent in current market yields less a deduction for expected and unexpected credit losses. The deduction for expected and unexpected credit losses is estimated using historical rating agency data and current market conditions, and varies by asset type, quality, and duration. The liquidity premium in the unobservable period is interpolated between the last observable liquidity premium and an ultimate liquidity premium (at year 70) specific to liquid or illiquid contracts. See Note 7.A in our Interim Consolidated Financial Statements for further details, which provides a weighted average summary of the discount curves used to present value cash flows for all major products that do not vary based on the returns on underlying items.

Current discount rates for cash flows that vary with returns on underlying items

Discount rates for cash flows that vary directly with returns on underlying items reflect that variability. For the portion of cash flows that is a pass through of returns on underlying items to policyholders, the discount rate is such that the present value of cash flows equals the portion of the underlying items that is passed through to policyholders. For cash flows that vary, but not directly, with underlying items (e.g., financial guarantees), scenario testing may be necessary. If so, discount rates used in the scenario projections are scenario-specific and based on the projected risk-free rates in the scenario plus liquidity premiums consistent with the liquidity characteristics of the contracts being measured.

Scenario Testing

Scenario testing may be required when the relationship between cash flows and financial risk variables is non-linear, or where there are complex interdependencies among cash flows. In scenario testing of financial risk variables, future cash flows are projected for each scenario path and discounted at the scenario-specific discount rates, resulting in a present value of future cash flows for each scenario. The provision for the projected cash flows is the average of the scenario-specific values. Assumptions for non-financial risk variables are the best estimate assumptions consistent with the scenario.

Scenarios are consistent with the current market environment. Our Economic Scenario Generator calibration process produces integrated stochastic scenarios of financial risk variables (e.g., risk-free interest rates, bond fund returns, equity returns) with parameters calibrated to replicate observable market prices of financial instruments available in the market. Adjustments are made when the insurance contracts being measured are illiquid but the financial instruments to which the scenarios are calibrated to are liquid.

42 Sun Life Financial Inc. Second Quarter 2023 MANAGEMENT'S DISCUSSION AND ANALYSIS

Risk Adjustment for Non-Financial Risk

The RA for insurance contracts issued is the compensation we require for bearing uncertainty about the amount and timing of the cash flows that arises from non-financial risk. This amount is measured as the present value of the difference between estimated future cash flows with a margin applied to non-financial assumptions and estimated future cash flows without this adjustment. Margins generally range from 5% to 20% depending on the uncertainty in the determination of the assumption. The level of uncertainty, and hence the margin chosen, varies by assumption and by line of business and other factors. Considerations that would generally lead to a choice of margin at the higher end of the range are as follows:

•The statistical credibility of our experience is too low to be the primary source of data for choosing the assumption;

•Future experience is difficult to estimate;

•The cohort of risks lacks homogeneity;

•Operational risks adversely impact the ability to estimate the assumption; or

•Past experience may not be representative of future experience and the experience may deteriorate.

Margins are generally stable over time and are revised only to reflect changes in the level of uncertainty in the assumptions. Our margins tend to be at mid-range.

The RA for reinsurance contracts held represents the amount of risk transferred to the reinsurer. This is measured as the difference between the RA on the underlying insurance contracts without reinsurance and what the RA on the underlying insurance contracts would be with reinsurance. The RA for reinsurance contracts held increases the asset or reduces the liability for reinsurance contracts held.

The RA for insurance contracts issued and reinsurance contracts held corresponds to a confidence level of approximately 80-85% overall.

Contractual Service Margin

The initial and subsequent measurement of CSM is described in 2.A.i. in our Interim Consolidated Financial Statements. Additional detail about certain components of the measurement of CSM is provided below.

Interest accretion

For insurance contracts measured using the GMA, locked-in discount rates are used to accrete interest on the CSM. The locked-in discount rate for a group of insurance contracts is the weighted average of the current discount rates at initial recognition of the contracts in the group. For groups of contracts that are in-force as at transition (January 1, 2022), the locked-in discount rates are the discount rates in effect at the date of transition as the fair value approach was applied for these groups at transition.

For insurance contracts measured using the VFA, there is no accretion of interest. Rather, the CSM is adjusted by the change in our share of the fair value of underlying items.

Changes in FCF relating to future service

For insurance contracts measured using the GMA, locked-in discount rates are used to measure changes in FCF relating to future service. Changes in FCF relating to future service reflect changes in non-financial assumptions but not changes in assumptions related to financial risk.

For insurance contracts measured using the VFA, current discount rates are used to measure the change in FCF relating to future service. Changes in FCF relating to future service reflect both changes in non-financial assumptions and changes in assumptions related to financial risk.

Changes in FCF relating to future service include (Liability for Remaining Coverage only):

•All changes related to investment component payments (including current period payments);

•Changes arising from changes in assumptions used to derive the present value of future cash flows - limited to non-financial assumptions for insurance contracts measured using the GMA;

•Changes in future cash flows arising from claims in the current period; and

•For insurance contracts measured using the GMA, changes related to discretionary cash flows on some universal life and adjustable products. Discretionary cash flows are cash flows outside the guaranteed payments to the policyholder, and are described as a spread on earned rates (in the case of some universal life contracts) and in the policy on criteria for changes to adjustable policies for adjustable policies.

CSM recognized for services provided

The amount of CSM recognized as insurance revenue in each period to reflect the insurance contract services provided for a group of contracts in the period is determined by:

•Identifying the total coverage units in the group (for services in current and future periods) – based on the quantity of insurance contract services;

•Allocating the CSM at the end of the period equally to each coverage unit in the current period and expected to be provided in the future (i.e., coverage units "unitize" the services provided); then

•Recognizing in insurance revenue the amount allocated to coverage units provided in the period.

Total coverage units for services expected to be provided in future periods is the present value of projected coverage units. The present value is measured using locked-in discount rates for groups measured using the GMA and current discount rates for groups measured using the VFA.

The coverage unit for a group is based on the nature of the insurance contract services provided. Insurance contract services comprise services for providing insurance coverage and, for some contracts, investment-return or investment-related services. It does not include services related to performing functions such as claims adjudication.

MANAGEMENT'S DISCUSSION AND ANALYSIS Sun Life Financial Inc. Second Quarter 2023 43

For insurance contracts measured using the VFA, coverage units are based on the policyholder's account value or the policyholders' share of the fair value of underlying items. For insurance contracts measured using the GMA, coverage units are based on the expected claim amount (excluding any investment component) for life and health insurance contracts, and the payment due in a period for annuity contracts.

For reinsurance contracts held, the amount of CSM recognized reflects the services received in the period.

Sensitivities to Insurance Methods and Assumptions

In addition to the insurance risks factors and risk management governance and controls described in section J - Risk Management in the 2022 Annual MD&A and the Risk Factors section of the 2022 AIF, we also note that on adoption of IFRS 17 and 9, the tables below include sensitivities of contractual service margins to insurance and other non-financial assumption risks.

The following table sets out the estimated immediate impact on, or sensitivity of, the CSM and net income to certain instantaneous changes in the insurance and other non-financial assumptions used in the calculation of our insurance contract liabilities, based on a starting point and business mix as at December 31, 2022. These estimates are illustrative and different starting points for best estimate assumptions, CSM balances and business mix will result in different estimated sensitivities. These sensitivities represent the Company's estimate of changes in best estimate assumptions that are reasonably likely based on the Company's and/or the industry's historical experience and industry standards and best practices as at December 31, 2022.

The impact on CSM is attributable to insurance contracts measured under the GMA and VFA. For insurance contracts measured under the GMA, the impact flows through the CSM at locked-in discount rates. For insurance contracts measured under the VFA, the impact flows through the CSM at current discount rates.

The impact on net income is attributable to any portion of the sensitivities for insurance contracts measured under the GMA and VFA that cannot be absorbed by CSM, the full impact for insurance contracts measured under the PAA, and the difference in impact between locked-in and current discount rates for insurance contracts measured under the GMA. If current discount rates are higher than locked-in rates, this generally results in a favourable impact to net income from contracts measured under the GMA.


($ millions)	As at December 31, 2022
Sensitivity(1)	Potential impact on CSM (pre-tax)	Potential impact on net income (after-tax)
Policyholder Behaviour (10% increase/decrease, where adverse)	(850)	75
Life Mortality rates (2% increase)	(75)	(25)

M. Internal Control Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting to provide reasonable assurance regarding the reliability of the Company's financial reporting and the preparation of its financial statements in accordance with IFRS.

During fiscal 2022, we continuously assessed the impact of internal controls over financial reporting and modified certain internal controls over financial reporting to reflect key changes in the Company's financial reporting and the preparation of its financial statements in the 2022 comparative reporting periods as a result of IFRS 17 and IFRS 9 implementations.

To manage our transition to IFRS 17 and IFRS 9, we established a comprehensive enterprise-wide governance structure to monitor the risks arising from changes to the financial reporting processes and controls related to finance, actuarial, asset and liability management, investments, and financial reporting-related system implementation. Throughout the transition, we have provided regular updates to senior management and the Audit Committee to ensure escalation of key issues and risks.

We believe there are no changes in the Company's internal control over financial reporting as a result of the adoption of new accounting standards during the period ended June 30, 2023 that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

2. Underlying Net Income and Underlying EPS

Underlying net income is a non-IFRS financial measure that assists in understanding Sun Life's business performance by making certain adjustments to IFRS income. Underlying net income, along with common shareholders’ net income (Reported net income), is used as a basis for management planning, and is also a key measure in our employee incentive compensation programs. This measure reflects management's view of the underlying business performance of the company and long-term earnings potential. For example, due to the longer term nature of our individual protection businesses, market movements related to interest rates, equity markets and investment properties can have a significant impact on reported net income in the reporting period. However, these impacts are not necessarily realized, and may never be realized, if markets move in the opposite direction in subsequent periods or in the case of interest rates, the fixed income investment is held to maturity.

Effective January 1, 2023, we refined the definition of underlying net income as follows, and have updated prior period comparative figures to reflect these changes: (i) Market-related impacts was updated to reflect the adoption of IFRS 17 and IFRS 9; (ii) The adjustment for management’s ownership of MFS shares were updated to better reflect Sun Life’s interest in MFS’ earnings; and (iii) Removal of intangible asset amortization on acquired finite-life intangibles. Additional detail on these adjustments is provided below.

Underlying net income removes the impact of the following items from reported net income:

•Market-related impacts reflecting the after-tax difference in actual versus expected market movements, including:

i)Net interest impact from risk-free rate, credit spread, and swap spread movements, reflecting accounting mismatches between assets and liabilities:

a.Differences arising from fair value changes(1) of fixed income assets (including derivatives) measured at fair value through profit or loss ("FVTPL") supporting insurance contracts, compared to fair value changes of the liabilities(2);

b.Fair value changes of fixed income assets (including derivatives) measured at FVTPL supporting our investment contract liability and surplus portfolios(3); and

c.Tax-exempt investment income above or below expected long-term tax savings relating to our Canadian multi-national insurance operations.

ii)Non-fixed income investments where the weighted average expected return is approximately 2% per quarter, including:

a.Equity investments (including derivatives) supporting insurance contracts and surplus portfolios; and

b.Investment properties supporting insurance contracts and surplus portfolios.

•Assumptions changes and management actions ("ACMA") – captures the impact of method and assumption changes, and management actions on insurance and reinsurance contracts.

•Other adjustments:

i)Management’s ownership of MFS shares – this adjustment removes the change in fair value of MFS common shares owned by management.

ii)Acquisition, integration, and restructuring - expense and income related to acquisition or disposal of a business. Also includes expenses related to restructuring activities.

iii)Intangible asset amortization - removes the amortization expense associated with finite life intangible assets arising from acquisitions or business combinations excluding amortization of software and distribution agreements.

iv)Other – represents items that are unusual or exceptional in nature which management believes are not representative of the long-term performance of the Company.

Underlying EPS (diluted). This measure is used in comparing the profitability across multiple periods and is calculated by dividing underlying net income by weighted average common shares outstanding for diluted EPS, excluding the dilutive impact of convertible instruments. For additional information about the underlying net income, see above. For additional information about the composition of the EPS, please refer to Note 14 of our Interim Consolidated Financial Statements for the period ended June 30, 2023. For additional information about the SLEECS, please refer to Note 13 of our 2022 Annual Consolidated Financial Statements.

(1)For fixed income assets, Underlying Net Income includes credit experience from rating changes on assets measured at FVTPL, and the Expected credit loss (ECL) impact for assets measured at Fair value through other comprehensive income (FVOCI).

(2)Underlying net income is based on observable discount curves and exchange rates at the beginning of the period.

(3)Underlying net income for earnings on surplus includes realized gains (losses) on fixed income assets classified as FVOCI.

3. Additional Non-IFRS Financial Measures

Management also uses the following non-IFRS financial measures:

After-tax profit margin for U.S. Group Benefits. This ratio expresses U.S. Group Benefits underlying net income as a percentage of net premiums. It assists in explaining our results from period to period and measures profitability. This ratio is calculated by dividing underlying net income (loss) by net premiums for the trailing four quarters. There is no directly comparable IFRS measure.

Assets under administration (in SLC Management). AUA represents Client assets for which Sun Life provides administrative services. In Asset Management, AUA includes assets distributed by SLC Management's affiliate, Advisors Asset Management, Inc. There is no directly comparable IFRS measure.

Assets under management. AUM is a non-IFRS financial measure that indicates the size of our Company's assets across asset management, wealth, and insurance. There is no standardized financial measure under IFRS. In addition to the most directly comparable IFRS measures, which are the balance of General funds and Segregated funds on our Statements of Financial Position, AUM also includes Third-party AUM and Consolidation adjustments.

AUM not yet earning fees. This measure represents the committed uninvested capital portion of total AUM not currently earning management fees. The amount depends on the specific terms and conditions of each fund. There is no directly comparable IFRS measure.

Capital raising. This measure consists of increases in SLC Management's commitments from fund raising activities for all real estate, infrastructure and alternative credit Clients excluding leverage. Investment-grade fixed income capital raising consists of sales made to new Clients. There is no directly comparable IFRS measure.

Cash and other liquid assets. This measure is comprised of cash, cash equivalents, short-term investments, and publicly traded securities, net of loans related to acquisitions that are held at SLF Inc. (the ultimate parent company), and its wholly owned holding companies. This measure is a key consideration of available funds for capital re-deployment to support business growth.

Cash and other liquid assets (held at SLF Inc. and its wholly owned holding companies)	2,047	1,050

(1)Includes publicly traded bonds.

(2)Includes ETF Investments.

Constant currency. We remove the impacts of foreign exchange translation from certain IFRS and non-IFRS measures to assist in comparing our results from period to period. The impacts of foreign exchange translation is approximated by using the foreign exchange rates in effect during the comparative period, using the average or period end foreign exchange rates, as appropriate.

CSM Movement Analysis includes certain non-IFRS financial measures, detailed below, and also presents certain measures on a net basis to reflect how management views the business, compared to a gross basis in the Consolidated Financial Statements. Examples include i) The impacts of insurance contracts issued is presented net of reinsurance; ii) Impact of new business is presented net of acquisition expense gain/loss; and iii) Certain methodology changes are presented as an impact of change in assumptions, whereas the Consolidated Financial Statement presentation is a contract modification.

•Organic CSM Movement is comprised of the Impact of new insurance business, Expected movements from asset returns & locked-in rates, Insurance experience gains/losses, and CSM recognized for services provided.

•Impact of new insurance business on CSM, also referred to as "new business CSM", represents growth from sales activity in the period, including individual protection sales (excluding joint ventures), and defined benefit solutions and segregated fund wealth sales in Canada. New business CSM is presented net of acquisition expense gain/loss.

•Expected movements from asset returns & locked-in rates applies to variable fee approach ("VFA") and general measurement approach ("GMA") contracts. For VFA contracts, this component of the CSM movement analysis is comprised of two factors: (i) the expected return on underlying assets and (ii) the measurement of financial guarantees. The difference between actual and expected results are reported as the impact of markets. For GMA contracts, this component of the CSM includes the accretion of the CSM balance at locked-in rates, which refer to the term structure associated with locked-in discount rates, set when the insurance contract was sold or on transition to IFRS 17. Average locked-in rates increase with the passage of time on in-force business and new business added at current rates.

•Impact of markets & other includes the difference between actual and expected movement for VFA contracts for: (i) the return on underlying assets and (ii) the measurement of financial guarantees. Also includes other amounts excluded from Organic CSM Movement.

•Insurance experience gains/losses represents the current period impacts of insurance experience, resulting in a change in future cash flows that adjust CSM.

•Impact of change in assumptions represents the future period impacts of changes in fulfilment cash flows that adjust CSM.

•CSM market sensitivities. CSM market sensitivities are non-IFRS financial measures for which there are no directly comparable measures under IFRS so it is not possible to provide a reconciliation of these amounts to the most directly comparable IFRS measures.

MANAGEMENT'S DISCUSSION AND ANALYSIS Sun Life Financial Inc. Second Quarter 2023 49

Deployment. This measure represents the amount of capital that has been invested in the period, including leverage where applicable. Deployment also includes capital committed in infrastructure deals to be invested in specific assets. There is no directly comparable IFRS measure.

Drivers of Earnings. The Drivers of Earnings ("DOE") analysis provides additional detail on the sources of earnings, primarily for protection and health businesses, and explains the actual results compared to the longer term expectations. The DOE is presented on a reported and underlying common shareholders' basis. Within the net insurance service result, the underlying DOE provides detail on expected insurance earnings, impact of new insurance business and experience gains (losses). Within the net investment result, the underlying DOE provides detail on expected investment earnings, credit experience, earnings on surplus, and joint ventures & other. For more information, refer to the headings "Underlying net income and Underlying EPS", "Earnings on surplus", "Notable items attributable to reported and underlying net income", in this document.

Certain amounts in the DOE are presented on a net basis to reflect how management views the business, compared to a gross basis in the Consolidated Financial Statements. Examples include: i) Net investment result and Other expenses of the Asset Management operating segment are combined with Fee Income to report the net contribution to earnings; ii) Income for fee-based businesses is reported net of the associated expenses; iii) Carried interest in SLC Management within Fee Income excludes the carried interest that Sun Life does not participate in economically, and nets the non-controlling interest portion of the carried interest against fee income and expenses of consolidated funds; iv) Net investment results include assets returns net of the crediting rate for investment contract liabilities and the unwinding of and changes in the discount rate for insurance contract liabilities; v) Earnings on surplus reflects net spread earned from investment strategies; vi) Earnings attributable to the participating account are excluded; and vii) Assumption changes and management actions combines the amounts included in Net insurance service result and Net investment result.

Earnings on Surplus. This component of the Drivers of Earnings represents the net income earned on a company’s surplus funds. Earnings on Surplus is comprised of realized gains on fair value through other comprehensive income assets, as well as net investment returns on surplus, such as investment income, gains (losses) on seed investments and investment properties mark-to-market.

Experience-related items attributable to reported net income and underlying net income. These notable items attributable to reported net income and underlying net income are components of the Drivers of Earnings represents gains and losses that are due to differences between the actual results during the reporting period and management’s estimate of the expected longer-term returns on assets and liabilities (i.e. expected insurance earnings and expected investment earnings) at the start of the reporting period.

Fee earning AUM. FE AUM consists of assets managed by SLC Management, which are beneficially owned by Clients, on which we earn management fees for providing investment management, property management or advisory-related services. There is no directly comparable IFRS measure.

Fee-related earnings and Operating income. Fee-related earnings represent profitability of SLC Management's fee-related portfolios, and is calculated as Fee-related revenue less Fee-related expenses. Operating income represents profit realized from our business operations, and is calculated as the sum of Fee-related earnings, Investment income (loss) and performance fees, and Interest and other. Fee-related revenue represents all fee income, with the exception of performance fees, generated from third-party investors. Fee-related expenses represent all expenses directly related to generating fee revenue from third-party investors. Investment income (loss) and performance fees represent total income or loss from our seed investments, net of the related expenses. Interest and other represents performance fee compensation, our net interest income or expense and income from managing the General Account assets.

Fee-related earnings and Operating income are non-IFRS financial measures within SLC Management's Supplemental Income Statement, which enhances the comparability of SLC Management's results with publicly traded alternative asset managers. For more details, see our Supplementary Financial Information package for the quarter.

Financial leverage ratio. This ratio is an indicator of the Company's balance sheet strength measured by its proportion of capital qualifying debt in accordance with OSFI guidelines. This is calculated as the ratio of total debt plus preferred shares to total capital including the contractual service margin net of taxes, where debt consists of all capital-qualifying debt securities. Capital-qualifying debt securities consist of subordinated debt and innovative capital instruments. The CSM is included net of taxes because debts are repaid and serviced from available after-tax funds.

Effective January 1, 2023, the calculation for the financial leverage ratio was updated to include the CSM balance (net of taxes) in the denominator on adoption of IFRS 17 and IFRS 9.

Impacts of foreign exchange translation. To assist in comparing our results from period-to-period, the favourable or unfavourable impacts of foreign exchange translation are approximated using the foreign exchange rates, in effect during the comparative period, for several IFRS and Non-IFRS financial measures using the average or period end foreign exchange rates, as appropriate. Items impacting a reporting period, such as Revenue, Expenses, and Reported net income (loss) in our Consolidated Statements of Operations, as well as underlying net income (loss), and sales, are translated into Canadian dollars using average exchange rates for the appropriate daily, monthly, or quarterly period. For Assets and Liabilities in our Consolidated Statements of Financial Position, as well as the AUM and certain components of the Drivers of Earnings disclosure, period-end rates are used for currency translation purposes.

LICAT market sensitivities. LICAT market sensitivities are non-IFRS financial measures for which there are no directly comparable measures under IFRS so it is not possible to provide a reconciliation of these amounts to the most directly comparable IFRS measures.

Pre-tax fee related earnings margin. This ratio is a measure of SLC Management's profitability in relation to funds that earn recurring fee revenues, while excluding investment income and performance fees. The ratio is calculated by dividing fee-related earnings by fee-related revenues and is based on the last twelve months. There is no directly comparable IFRS measure.

Pre-tax net operating margin. This ratio is a measure of the profitability and there is no directly comparable IFRS measure. For MFS, this ratio is calculated by excluding management's ownership of MFS shares and certain commission expenses that are offsetting. These commission expenses are excluded in order to neutralize the impact these items have on the pre-tax net operating margin and have no impact on the profitability of MFS. For SLC Management, the ratio is calculated by dividing the total operating income by fee-related revenue plus investment Income (loss) and performance fees, and is based on the last twelve months.

MANAGEMENT'S DISCUSSION AND ANALYSIS Sun Life Financial Inc. Second Quarter 2023 51

The following table provides a reconciliation to calculate MFS' pre-tax net operating margin:


MFS	Quarterly results			Year-to-date

(1)Other includes accounting basis differences, such as sub-advisory expenses and product allowances.

(2)Excluding non-controlling interest. For more information on Management's ownership of MFS shares, see the heading Underlying Net Income and Underlying EPS.

Return on equity. IFRS does not prescribe the calculation of ROE and therefore a comparable measure under IFRS is not available. To determine reported ROE and underlying ROE, respectively, reported net income (loss) and underlying net income (loss) is divided by the total weighted average common shareholders’ equity for the period. The ROE provides an indication of the overall profitability of the Company. The quarterly ROE is annualized.

Sales and flows. Asset Management gross flows includes funds from retail and institutional Clients; SLC Management gross flows include capital raising, such as uncalled capital commitments and fund leverage. Asset Management net flows consist of gross flows less gross outflows; SLC Management's net flows do not include Client distributions from the sale of underlying assets in closed-end funds. In Canada and in Asia, net sales consist of wealth sales & asset management gross flows less redemptions. In Canada, wealth sales & asset management gross flows consist of sales in Group Retirement Services and Individual Wealth; group - health & protection sales consist of workplace benefits sold by Sun Life Health; and individual - protection sales refer to individual insurance sales. In the U.S., group - health & protection sales consist of sales by Group Benefits and Dental. In Asia, wealth sales & asset management gross flows consist of Hong Kong wealth sales & asset management gross flows, Philippines mutual fund sales, wealth sales & asset management gross flows by our India and China joint ventures and associates, and Aditya Birla Sun Life AMC Limited's equity and fixed income mutual fund sales based on our proportionate equity interest, including sales as reported by our bank distribution partners; individual - protection sales consist of the individual insurance sales, by our subsidiaries and joint ventures and associates, based on our proportionate equity interest, in the Philippines, Indonesia, India, China, Malaysia, Vietnam, International, Hong Kong and Singapore. Asia also has group - health & protection sales in the Philippines, Hong Kong and our joint ventures. To provide greater comparability across reporting periods, we exclude the impacts of foreign exchange translation from sales and gross flows. There is no directly comparable IFRS measure.

Effective January 1, 2023, wealth sales & asset management gross flows in Group Retirement Services in Canada has been updated to exclude retained sales to better align with the methodology for Life Insurance Marketing and Research Association ("LIMRA") reporting. We have updated prior period amounts to reflect this change. Also effective January 1, 2023, insurance sales were renamed to "Group - Health & Protection sales" and "Individual - Protection sales" to better align to the business types within our business groups. For more information about business types, refer to section A - How We Report Our Results in this document.

Third-party AUM. Third-party AUM is composed of retail, institutional, and other third party assets, which includes general fund and segregated fund assets managed by our joint ventures. In Asset Management, third-party AUM includes Client assets for retail and institutional Clients, as well as capital raising, such as uncalled commitments and fund leverage in SLC Management. In Canada, third-party AUM includes Client assets in retail mutual fund products of Sun Life Global Investments. In Asia, third-party AUM includes Client assets in Hong Kong managed fund products, International wealth & asset management products, Philippines mutual and managed fund products, Aditya Birla Sun Life AMC Limited equity and fixed income mutual fund products, Sun Life Everbright Asset Management products and our joint ventures’ general fund and segregated fund assets based on our proportionate equity interest. There is no directly comparable IFRS financial measure.

Effective January 1, 2023, this measure was renamed to "third-party AUM", formerly "other AUM", in order to be more descriptive of the nature of these assets. Further, the presentation of "consolidation adjustments" has been updated in the current and prior periods to be shown separately from "third-party AUM", as consolidation adjustments apply to all components of total AUM.

Total weighted premium income ("TWPI"). This measure consists of 100% renewal premiums, 100% of first year premiums, and 10% of single premiums. In contrast to sales, which only includes premiums from new business, TWPI includes renewal premiums, reflecting the strength of the in-force block and providing a better understanding of both new and existing business. There is no directly comparable IFRS measure.

Underlying dividend payout ratio. This is the ratio of dividends paid per share to diluted underlying EPS for the period. The ratio is utilized during the medium-term capital budgeting process to inform our planned capital initiatives. We target an underlying dividend payout ratio of between 40% and 50% based on underlying EPS. For more information, see Section I - Capital and Liquidity Management in the 2022 Annual MD&A.

52 Sun Life Financial Inc. Second Quarter 2023 MANAGEMENT'S DISCUSSION AND ANALYSIS

Underlying effective tax rate. This measure is calculated using the pre-tax underlying net income and the income tax expense associated with it. Our statutory tax rate is normally reduced by various tax benefits, such as lower taxes on income subject to tax in foreign jurisdictions, a range of tax-exempt investment income, and other sustainable tax benefits. Our effective tax rate helps in the analysis of the income tax impacts in the period.

(1)IFRS 17 and IFRS 9 were adopted on January 1, 2023, see Note 2 of the Interim Consolidated Financial Statements for the period ended June 30, 2023. The after-tax profit margin is on a trailing four-quarter basis, and thus the Q2'22 margin reflects underlying net income on an IFRS 4 and IAS 39 basis.

(2)Effective Q2’22, we began reporting on the performance and results of our Dental business unit, which represents our existing dental and vision business within Group Benefits together with DentaQuest, acquired on June 1, 2022. We have updated prior periods to reflect this change in presentation.

(3)For a breakdown of this adjustment made to arrive at a non-IFRS financial measure, see the heading Underlying Net Income and Underlying EPS.

(4)2022 restated results may not be fully representative of our future earnings profile, as we were not managing our asset and liability portfolios under the new standards, IFRS 17 and IFRS 9. For more details, see the heading "Note to Readers: 2022 Restated Results on Adoption of IFRS 17 and IFRS 9" in this document.

1. General Information

Description of Business

Sun Life Financial Inc. ("SLF Inc.") is a publicly traded company domiciled in Canada and is the holding company of Sun Life Assurance Company of Canada ("Sun Life Assurance"). SLF Inc. and its subsidiaries are collectively referred to as "us", "our", "ours", "we", or "the Company".

Our Interim Consolidated Financial Statements have been prepared in accordance with International Accounting Standard ("IAS") 34 Interim Financial Reporting as issued and adopted by the International Accounting Standards Board ("IASB"). We have used accounting policies which are consistent with our accounting policies in our 2022 Annual Consolidated Financial Statements, except as updated in Note 2 below. Our Interim Consolidated Financial Statements should be read in conjunction with our 2022 Annual Consolidated Financial Statements, as interim financial statements do not include all the information incorporated in annual consolidated financial statements prepared in accordance with International Financial Reporting Standards ("IFRS") as issued by the IASB.

2. Summary of Accounting Policies

Our material accounting policies and future changes in accounting policies that are not yet effective for us are disclosed in Note 1 and Note 2 of our 2022 Annual Consolidated Financial Statements.

2.A New and Amended International Financial Reporting Standards Adopted in 2023

We adopted the following new and amended IFRS on January 1, 2023.

2.A.i IFRS 17 Insurance Contracts ("IFRS 17")

Summary

In May 2017, the IASB issued IFRS 17, with an amendment issued in June 2020 to defer the effective date of IFRS 17 to annual periods beginning on or after January 1, 2023. This standard is to be applied using a retrospective approach, with at least one year of comparative results provided. If retrospective application to a group of insurance contracts is impracticable, a modified retrospective or fair value approach may be used. IFRS 17 replaces IFRS 4 Insurance Contracts ("IFRS 4") and impacts how we recognize, measure, present, and disclose our insurance contracts in our Consolidated Financial Statements.

IFRS 17 and IFRS 9 Financial Instruments ("IFRS 9") were effective for us beginning January 1, 2023. Restated comparative period results have been provided for IFRS 17. As permitted by IFRS 9, we elected not to restate comparative period results, and as permitted by IFRS 17, we have elected to present comparative information on financial assets as if IFRS 9 were applicable during the comparative period.

IFRS 17 establishes principles for the recognition, measurement, presentation, and disclosure of insurance contracts. The key principles of IFRS 17 are as follows:

•Insurance contracts issued and reinsurance contracts held are divided into groups that will be separately recognized and measured.

•Insurance revenue, insurance service expenses and insurance finance income or expenses are presented separately.

Significant Differences between IFRS 17 and IFRS 4

The following section describes the most significant differences between IFRS 17 and the accounting policies applied under IFRS 4.

Scope

Measurement

The measurement of insurance contracts under IFRS 17 differs from the Canadian Asset Liability Method ("CALM") previously applied under IFRS 4. The most significant differences by measurement component are as follows:

Present value of future cash flows:

•The discount rates used to present value future cash flows under IFRS 17 are based on the characteristics of the insurance contracts. Under IFRS 4, the CALM is used to determine actuarial liabilities based on the portfolio of assets currently supporting the insurance contract liabilities and reinvestment assumptions.

•Expense cash flows under IFRS 17 are limited to those directly attributable to fulfilment of the obligations under insurance contracts.

•Future income taxes are excluded from future cash flows under IFRS 17.

Risk adjustment for non-financial risk:

•Measures the compensation required for uncertainty related to non-financial risk, such as mortality, morbidity, surrender and expenses under IFRS 17.

•Provisions for uncertainty related to financial risk are implicitly included in the present value of future cash flows under IFRS 17.

•No amount is provided for asset-liability mismatch risk under IFRS 17.

•Under IFRS 4, amounts provided for the risks listed above are reflected in a provision for adverse deviations included in insurance contract liabilities.

CSM:

•This is a new component of liabilities and necessitates the "grouping" of insurance contracts, which is not required under IFRS 4.

•The CSM represents unearned profits, as discussed above.

The measurement approaches under IFRS 17 and IFRS 4 are similar for insurance contracts measured using the PAA. Differences arise mainly in the measurement of the liability for incurred claims ("LIC"), where the discount rate and risk adjustment for non-financial risk changes noted above apply.

Revised Accounting Policies

The material accounting policies used in the preparation of these Consolidated Financial Statements as a result of the adoption of IFRS 17 are summarized below. These policies differ from those included in Note 1 of our 2022 Annual Consolidated Financial Statements.

Insurance Contracts

Classification

Insurance contracts are comprised of insurance contracts issued, which are insurance and reinsurance or retrocession contracts that are issued by us, and reinsurance contracts held.

Insurance contracts issued are contracts under which we accept significant insurance risk from a policyholder by agreeing to compensate the policyholder if a specified uncertain future event adversely affects the policyholder. The presence of significant insurance risk in individual contracts is assessed by reviewing books of contracts with homogeneous risk features.

Reinsurance contracts held are insurance contracts under which we are the policyholder and have transferred insurance risk to the issuer of the contract, either the reinsurer or the retrocessionaire. In the normal course of business, we use reinsurance to limit our exposure to large losses. We have a retention policy that requires that such arrangements be placed with well-established, highly-rated reinsurers.

Certain investment contracts contain DPF, whereby the policyholder has the right to receive, in addition to guaranteed amounts, potentially significant benefits based on returns on a specified pool of assets. For entities like us that issue insurance contracts, investment contracts with DPF are measured and reported as insurance contracts.

Judgment is required to determine the classification of a contract as an insurance contract, investment contract or a service contract. Contracts are classified at initial recognition. Once a contract is classified as an insurance contract, it remains an insurance contract until all rights and obligations are extinguished or the contract is derecognized.

Combination and Separation of Contracts

Derivatives embedded in insurance contracts are treated as separate contracts and measured at fair value with changes in fair value recognized in income unless the embedded derivative itself meets the definition of an insurance contract or when the risks and characteristics of the embedded derivative are closely related to those of the host contract. Embedded derivatives that are not separated are accounted for with the host insurance contract.

Investment components of insurance contracts are amounts we repay to a policyholder in all circumstances (e.g., cash surrender values). Investment components of insurance contracts are treated as separate investment contracts only if the investment component is not highly interrelated with the insurance component and a contract with equivalent terms could be sold separately in the same market. Investment components that are not separated are accounted for as non-distinct investment components of insurance contracts.

Service components of insurance contracts are treated as separate service contracts only if the service component is not highly interrelated with the insurance component and we provide no significant service in integrating the service component with the insurance component. Service components that are not separated are accounted for with insurance contracts.

Insurance components of insurance contracts are treated as separate contracts only if the insurance component constitutes a separate insurance contract (e.g., certain reinsurance treaties that transfer risk on different types of insurance contracts).

For insurance contracts where both parties to the contract have the practical ability to terminate the contract, the extension of the contract beyond the termination date is treated as a new and separate contract. This occurs for most group life and health insurance contracts every year, when we have the right to reprice the contract and the policyholder has the option to not renew the contract. In such instances, each renewal is considered a new and separate contract. This also applies for many reinsurance contracts held, where the reinsurer has the right to reprice new cessions and we

64 Sun Life Financial Inc. Second Quarter 2023 CONDENSED NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

have the right to cease ceding new contracts with a notice period. In such instances, the cessions within each notice period are considered a new and separate reinsurance contract held.

Measurement

Insurance contracts are measured in accordance with Canadian accepted actuarial practice, including IFRS 17, using one of the following approaches:

•VFA: This approach applies to insurance contracts (excluding reinsurance contracts) with direct participation features, which are substantially investment-related service contracts where the policyholder is promised an investment return based on underlying items.

•PAA: This is a simplified measurement approach and is applied to all insurance contracts that are eligible to use it, such as the majority of those in our group life and health businesses.

•GMA: This approach applies to all insurance contracts not measured using the VFA or the PAA.

Reinsurance contracts held are measured in a manner consistent with the associated underlying insurance contracts and in accordance with the terms of each reinsurance contract held. Reinsurance contracts held cannot be measured using the VFA. The measurement of reinsurance contracts held includes a provision for the risk that the reinsurer will not honour its obligations under the contract.

The carrying value of insurance contracts comprises the liability for remaining coverage ("LRC") and the LIC:

•The LRC is the measurement of our obligation to investigate and pay valid claims for insured events that have not yet occurred (i.e., the obligation that relates to the unexpired portion of the coverage period).

•The LIC is the measurement of our obligation to investigate and pay valid claims for insured events that have already occurred, including events that have occurred but for which claims have not been reported. For reinsurance contracts held, the LIC is an asset for incurred claims.

•For blocks of businesses acquired prior to January 1, 2023, any previously incurred claims where the amount paid to the beneficiary is subject to insurance risk are treated as LIC. For blocks of businesses acquired on or after January 1, 2023, such claims are treated as LRC.

Significant judgment is required in measuring assets or liabilities for insurance contracts, including the assumptions that are used for their measurement. Application of different assumptions may result in different measurement of the insurance contracts. Actual experience may differ from assumptions, and estimates may change from period to period based on future events or revisions of assumptions. Key assumptions and considerations in selecting these assumptions as well as the sensitivity of the measurement of insurance contracts to changes in risk variables are discussed in Note 2.B.

Level of Aggregation

The unit of account for the measurement of insurance contracts is a group. Each insurance contract is assigned to a group at initial recognition and remains in that group until the insurance contract is derecognized.

Groups are subdivisions of portfolios. Portfolios are insurance contracts subject to similar risks and managed together, and a portfolio is the level at which expenses are attributed and the level at which insurance contracts issued and reinsurance contracts held are presented.

We have established portfolios in each reportable business segment, distinguished between:

•Insurance contracts issued and reinsurance contracts held;

•Group insurance contracts and individual insurance contracts;

•Participating insurance contracts and non-participating insurance contracts;

•Adjustable insurance contracts and non-adjustable insurance contracts;

•Traditional life insurance contracts and universal life insurance contracts; and

•Pass-through insurance contracts and discretionary crediting contracts.

Within each portfolio, separate groups are established by:

•Date of issue: To be in the same group, contracts must be issued within the same time period, and the period cannot be longer than one year; and

•Level of profitability: Insurance contracts are separated into groups of contracts that are onerous at initial recognition, contracts that do not have a significant possibility of becoming onerous subsequently, and other contracts. The level of profitability for an insurance contract is based on the CSM at initial recognition of the contract (as described below in Initial Measurement).

We do not establish additional groups beyond the minimum required except for some portfolios of reinsurance contracts held where grouping is established to line up with the grouping of the underlying insurance contracts issued.

Initial Measurement

Groups of insurance contracts are recognized and measured as the total of the following measurement components:

•Fulfilment cash flows ("FCF"), which is comprised of:

–The present value of future cash flows (including the provisions for financial risk), and

–The risk adjustment for non-financial risk; and

•A CSM, representing the unearned profit that will be recognized in income as insurance contract services are provided.

These measurement components apply to groups of insurance contracts measured using the GMA and the VFA. Under the PAA, which is a simplified measurement approach, insurance contracts are measured based on unearned profits and do not include a CSM.

CONDENSED NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) Sun Life Financial Inc. Second Quarter 2023 65

GMA or VFA

Using the GMA or VFA, a group of insurance contracts is measured as the total of the three measurement components, as described above.

Estimates of the present value of future cash flows are explicit and current, and consider all reasonable and supportable information available at the reporting date without undue cost or effort. The portion of the present value of future cash flows related to financial risk variables is consistent with observable market prices and, where necessary, considers a range of scenarios that provides a good representation of possible outcomes. The cash flows for each scenario are probability-weighted and discounted using current assumptions.

The risk adjustment for non-financial risk represents the compensation required for uncertainty related to non-financial risk (mortality, morbidity, surrender and expenses, etc.). The risk adjustment is reduced as the non-financial risks of our insurance contracts diminish over time ("release of risk adjustment").

The CSM at the initial recognition of an insurance contract issued is the amount that fully offsets the FCF at initial recognition, and represents unearned profits on new business that are deferred and only amortized into income as insurance contract services are provided. For insurance contracts issued that are not profitable at initial recognition ("onerous insurance contracts"), a CSM is not established and losses are recognized in income immediately.

For reinsurance contracts held, there is no restriction on the CSM based on profitability at initial recognition, and any losses are deferred in the same manner as profits. In addition, the CSM for reinsurance contracts held can be adjusted to offset any gains or losses on the groups of underlying direct contracts that would have gone through CSM if the group of underlying direct contracts had a CSM balance.

For onerous insurance contracts, the loss recognized in the Consolidated Statements of Operations at initial recognition is added to the loss component of the group to which the contract is assigned. The loss component is a notional portion of the LRC that represents the amount of loss that can be reversed by future profit before a CSM is re-established for the group. For groups of reinsurance contracts held for which the CSM has been adjusted to offset gains and losses on groups of underlying direct contracts without a CSM, a loss recovery component is established.

PAA

For groups of insurance contracts using the PAA, there is no liability established at initial recognition, unless factors indicate that the group is onerous, in which case the group is initially recognized at the amount it is onerous, and a loss of that amount is recognized in the Consolidated Statements of Operations and becomes the loss component of the group. For groups using the PAA, insurance acquisition cash flows are recognized in the Consolidated Statements of Operations when incurred, rather than including such expenses in the measurement of LRC.

Subsequent Measurement

The subsequent measurement of FCF uses the same approach as described above for initial measurement, but with current inputs for each subsequent reporting date.

For contracts measured using the PAA, the LRC subsequent to initial recognition is the amount of unearned revenue and the remaining loss component for any groups that are onerous. We do not adjust the LRC to reflect the time value of money and the effects of financial risk when we expect the time between providing coverage and the related premiums to be no more than one year. We do not adjust the LIC to reflect the time value of money and the effects of financial risk when we expect the claims to be fully paid within one year of the insured event occurring.

For contracts measured using the GMA or VFA, the measurement of CSM subsequent to initial recognition is described below.

For groups of insurance contracts issued using the GMA, the CSM at the end of a reporting period is measured as the CSM at the beginning of the reporting period, adjusted for:

•The effect of any new contracts added to the group;

•Interest accretion on the carrying amount of the CSM;

•The change in FCF relating to future service, except to the extent that increases exceed the carrying amount of the CSM (giving rise to a loss) or decreases are allocated to the loss component of the LRC (reversing a prior loss);

•The effect of any currency exchange differences on the CSM; and

•The amount recognized as Insurance revenue due to the performance of insurance contract services in the period ("CSM amortization").

For groups of insurance contracts issued using the VFA, the CSM at the end of a reporting period is measured as the CSM at the beginning of the reporting period, adjusted for:

•The effect of any new contracts added to the group;

•The change in the entity's share of the fair value of underlying items, except to the extent a decrease exceeds the carrying amount of the CSM (giving rise to a loss) or an increase reverses a prior loss, or that risk mitigation applies (see below);

•The effect of any currency exchange differences on the CSM; and

•CSM amortization.

The risk mitigation option is provided to avoid accounting mismatches that would otherwise occur when the financial risk of a group of insurance contracts is mitigated outside the underlying items of the group. For insurance contracts issued using the VFA, changes related to financial risk adjust the CSM, but offsetting changes from risk mitigation (e.g., derivatives) may go through income. The risk mitigation option allows for a change that would otherwise adjust CSM to be recognized in income instead, to avoid such a mismatch. We apply the risk mitigation option where applicable to reduce accounting mismatches. The effect on CSM of applying the risk mitigation option is disclosed in more detail in Note 5.C.

66 Sun Life Financial Inc. Second Quarter 2023 CONDENSED NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

For groups of reinsurance contracts held, the CSM at the end of a reporting period is measured as the CSM at the start of the reporting period, adjusted for:

•The effect of any new contracts added to the group;

•Interest accretion on the carrying amount of the CSM;

•Income recognized in the reporting period as a result of gains or losses recognized to offset gains or losses on groups of underlying direct contracts with no CSM;

•Reversals of a loss-recovery component to the extent those reversals are not changes in the FCF of the group of reinsurance contracts held;

•The change in FCF relating to future service, unless the change offsets a gain or loss on groups of underlying direct contracts with no CSM or the change is related to groups of onerous insurance contracts using the PAA;

•The effect of any currency exchange differences on the CSM; and

•The amount recognized in income due to services received in the period.

We have not changed the accounting estimates made in previous interim financial statements in the preparation of these Consolidated Financial Statements. In particular, the CSM at the end of each reporting period is the CSM at the beginning of the reporting period adjusted as described above, rather than the CSM at the beginning of the calendar year adjusted as described above.

Presentation on the Consolidated Financial Statements

The carrying value of portfolios of insurance contracts issued and reinsurance contracts held that are in an asset position are presented as Insurance contract assets and Reinsurance contract held assets in the Consolidated Statements of Financial Position, while the carrying value of portfolios of insurance contracts issued and reinsurance contracts held that are liabilities are presented as Insurance Contract liabilities excluding those for account of segregated fund holders and Reinsurance contract held liabilities. Assets for insurance acquisition cash flows incurred before initial recognition of the contracts to which they are attributable are included in the carrying value of the portfolio associated with those contracts.

Amounts related to insurance contracts that impact income are included in the Net insurance service result of the Consolidated Statements of Operations and the Insurance finance income (expenses) line in the Net investment result section. Results in those sections are presented separately for insurance contracts issued and reinsurance contracts held. We have chosen to disaggregate changes in the RA between the Insurance revenue line in Net insurance service result, and the Insurance finance income (expenses) line in Net investment result.

Net insurance service result

Insurance revenue is recognized as insurance contract services are provided for groups of insurance contracts. For insurance contracts issued that are measured using the GMA or the VFA, Insurance revenue includes the following services for which consideration in the form of premiums, net of premium taxes, is expected to be received:

•Expected claims and other expenses directly attributable to fulfilling insurance contracts, measured at the amounts expected at the beginning of the period, and excluding investment components and amounts allocated to the loss component;

•Release of the RA for the period, excluding amounts allocated to the loss component and amounts related to changes in the time value of money, which are recognized in Insurance finance income (expenses);

•CSM amortization to reflect services provided in the period, measured using the coverage units for the reporting period as a proportion of total coverage units (additional detail on coverage units is provided in Note 2.B);

•Amortization of insurance acquisition cash flows;

•Premium experience adjustments that relate to current or past service; and

•Expected amounts related to income taxes specifically chargeable to the policyholder.

Amortization of insurance acquisition cash flows in Insurance revenue is an allocation of the portion of the premiums that relates to the recovery of insurance acquisition cash flows, determined in a systematic way based on the passage of time. An equal and offsetting amount is included in Insurance service expenses.

For insurance contracts issued measured using the PAA, expected premium receipts (net of premium taxes and excluding investment components) are recognized as revenue, generally based on the passage of time.

Insurance service expenses include:

•Claims incurred in the period (excluding investment components and amounts allocated to the loss component),

•Expenses incurred that are directly attributable to fulfilling the insurance contracts;

•Losses on onerous contracts and reversals of those losses;

•Changes related to past service (e.g., changes in the LIC in periods subsequent to the claim being incurred);

•Amortization of insurance acquisition cash flows;

•Insurance acquisition cash flows expensed as incurred related to PAA contracts; and

•Impairment and reversals of impairment of assets for insurance acquisition cash flows.

For reinsurance contracts held, we have elected to present income and expenses arising from these contracts as a single amount in the Reinsurance contract held net income (expense) line on the Consolidated Statements of Operations. This amount includes an allocation of reinsurance premiums, amounts recovered from reinsurers, and changes in the risk of non-performance by the reinsurer. Allocations of reinsurance premiums are recognized as services are received for the reinsurance contract held.

For reinsurance contracts held measured using the GMA, the services received for which consideration is paid include:

•Expected recoveries and expenses, excluding amounts that are paid regardless of claims;

•Release of the RA for the period;

•CSM recognized for services received; and

•Premium experience adjustments that relate to current or past service.

CONDENSED NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) Sun Life Financial Inc. Second Quarter 2023 67

For reinsurance contracts held measured using the PAA, expected premium payments (net of premium taxes and excluding amounts that are paid regardless of claims) are recognized as an allocation of reinsurance premiums based on the passage of time. Amounts recovered from reinsurers includes incurred claims (excluding amounts that are paid regardless of claims) and expenses, loss recoveries and reversals of loss recoveries, and changes related to past service (e.g., changes in the asset for incurred claims in periods subsequent to the claim being incurred).

Insurance finance income (expenses)

Changes in the carrying value of insurance contracts issued not measured using the VFA and reinsurance contracts held that are due to changes in the time value of money and in financial risk are recognized in the Insurance finance income (expenses) line on the Consolidated Statements of Operations. For insurance contracts issued measured using the VFA, Insurance finance income (expenses) includes changes in the fair value of underlying items and changes not recognized in the CSM when the risk mitigation option is applied. We have elected to recognize all insurance finance income (expenses) in the Consolidated Statements of Operations and not in Other comprehensive income. Insurance finance income (expense) for insurance contracts for account of segregated fund holders is discussed in the Segregated Funds section of this Note.

Derecognition and Modification

Insurance contracts are derecognized when the obligations in the contract expire, are discharged or cancelled, or when it is modified and the modification is substantial, such as when the modification results in a change in the measurement approach. When a contract modification results in derecognition, the original contract is derecognized and the modified contract is recognized as a new contract. Modifications that do not result in derecognition are treated as changes in FCF.

Segregated Funds

Segregated funds are products where the benefit amount is directly linked to the fair value of the investments held in the particular segregated fund. Although the underlying assets are registered in our name and the segregated fund contract holder has no direct access to the specific assets, the contractual arrangements are such that the segregated fund policyholders bear the risks and rewards of the fund’s investment performance. In addition, certain segregated funds contracts include guarantees from us. Segregated fund contracts are classified as insurance contracts or investment contracts following the classification criteria described in the Insurance Contracts section of this Note and Note 2.A.ii.

Investments for Account of Segregated Fund Holders

Investments for account of segregated fund holders are recorded separately from the Total general fund assets in our Consolidated Statements of Financial Position and are carried at fair value. Fair values are determined using quoted market values or, where quoted market values are not available, estimated fair values as determined by us. Investments for account of segregated fund holders includes investments for contracts that are classified as insurance contracts and investments for contracts that are classified as investment contracts. Unrealized gains and losses and other investment income from investments for account of segregated fund holders classified as insurance contracts is reported as Net investment income (loss) within the Net investment result for insurance contracts for account of segregated fund holders in the Consolidated Statements of Operations. Such investment income (loss) will be offset by the corresponding increase in the insurance contract liabilities for account of segregated fund holders. Changes in the fair value of the investments for account of segregated fund holders classified as investment contracts are recorded in net realized and unrealized gains (losses) within the segregated fund and are not recorded in our Consolidated Statements of Operations.

Insurance Contract Liabilities for Account of Segregated Fund Holders

Segregated fund products classified as insurance contracts are contracts with direct participation features and are therefore measured using the VFA described in the Insurance contracts section of this Note. Insurance contract liabilities for these contracts are presented as two separate lines on the Consolidated Statements of Financial Position: Insurance contract liabilities excluding those for account of segregated fund holders, and Insurance contract liabilities for account of segregated fund holders. The Insurance contract liabilities for account of segregated fund holders represents the obligation to pay the policyholder an amount equal to the fair value of the underlying items. Changes in this obligation due to changes in fair value of the underlying items are recognized as Insurance finance income or expenses in the Net investment result for insurance contracts for account of segregated fund holders in the Consolidated Statements of Operations. Such insurance finance income or expenses will be offset by the corresponding increase in Investments for account of segregated fund holders. Deposits into and payments from the segregated funds are investment components and thus excluded from insurance revenue and insurance service expenses. The Insurance contract liabilities excluding those for account of segregated fund holders on the Consolidated Statements of Financial Position includes the remaining insurance contract liabilities for these contracts, which comprises the provision for guarantees, future expenses (less future fees), the RA and the CSM. Revenue and expenses related to these items are included in the Insurance service result on the Consolidated Statements of Operations.

Investment Contract Liabilities for Account of Segregated Fund Holders

Investment contract liabilities for account of segregated fund holders are recorded separately from the Total general fund liabilities in our Consolidated Statements of Financial Position. The liabilities reported as Investment contracts for account of segregated fund holders are measured at the aggregate of the policyholder account balances. We derive fee income from segregated funds classified as investment contracts, which is included in Fee income in our Consolidated Statements of Operations. Deposits to segregated funds and payments made from segregated funds are reflected as increases or decreases in Investment contract liabilities for account of segregated fund holders and Investments for account of segregated fund holders and are not reported as revenues or expenses in our Consolidated Statements of Operations.

Foreign Currency Translation

Translation of Transactions in Foreign Currencies

The financial results of SLF Inc. and its subsidiaries, joint ventures and associates are prepared in the currency in which they conduct their ordinary course of business, which is referred to as functional currency. Transactions occurring in currencies other than the functional currency are translated to the functional currency using the spot exchange rates at the dates of the transactions.

Monetary assets and liabilities in foreign currencies are translated to the functional currency at the exchange rate at the statement of financial position date. Insurance contract and reinsurance contract held assets and liabilities, including the CSM, are monetary items. Non-monetary assets and liabilities in foreign currencies that are held at fair value are translated using the exchange rate at the statement of financial position date, while non-monetary assets and liabilities that are measured at historical cost are translated using the exchange rate at the date of the transaction.

68 Sun Life Financial Inc. Second Quarter 2023 CONDENSED NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

The resulting exchange differences from the translation of monetary items and non-monetary items held at fair value, with changes in fair value recorded to income, are recognized in our Consolidated Statements of Operations. For monetary assets classified as fair value through other comprehensive income ("FVOCI"), translation differences calculated on amortized cost are recognized in our Consolidated Statements of Operations and other changes in carrying amount are recognized in other comprehensive income ("OCI"). The exchange differences from the translation of non-monetary items on these assets are recognized in OCI.

Transition Impacts

Transition Method

The retrospective application of IFRS 17 at the transition date of January 1, 2022, was implemented using the fair value approach where a full retrospective approach was impracticable. The full retrospective approach was deemed impracticable for all groups of insurance contracts measured using the GMA or VFA, because estimates required information that was either not available or would not have been available in a usable form in prior periods. For groups of insurance contracts measured using the PAA, we applied full retrospective measurement at transition.

Under the fair value approach, the CSM at transition for a group of insurance contracts is equal to the fair value of the group of insurance contracts less the fulfilment cash flows (which is the present value of future cash flows plus the risk adjustment for non-financial risk) measured using IFRS 17. The fair value of a group of insurance contracts is the amount that a market participant would require to take over the obligations of the group of insurance contracts.

Transition Grouping

As permitted under IFRS 17 when using the fair value approach, groups of insurance contracts at transition were formed according to the IFRS 17 grouping requirements, but without the restriction that groups should not contain contracts that are issued more than one year apart. Also, given the definition of fair value, all insurance contracts issued in a portfolio were in the same profitability group. Therefore, there was only one group for each portfolio of insurance contracts issued at transition. Portfolios of reinsurance contracts held at transition were grouped according to the grouping of the direct underlying contracts.

Fair Value Measurement

The fair value of a group of insurance contracts issued as at the transition date was measured using one of two approaches, the current pricing margin approach or the adjusted fulfilment cash flows approach. For both approaches, our requirements were considered a reasonable proxy for a market participant's requirements, as we share the characteristics of a typical market participant in the insurance market. The determination of fair value requires us to make estimates and assumptions that require significant judgment.

The "adjusted fulfilment cash flows" approach identifies specific amounts a market participant would require, in addition to the fulfilment cash flows, to take over the obligations of the group. These include:

•A provision for reinvestment risk, which was measured as the cost of capital for interest rate risk using the higher of the Life Insurance Capital Adequacy Test ("LICAT") and local capital requirements;

•An amount for overhead and other non-directly attributable expenses not covered by fulfilment cash flows; and

•Other adjustments, including a provision for general operational risk and an amount to compensate for the expectation, as at the transition date, that CSM would not be tax-deductible.

The current pricing margin approach identifies the amount a market participant would require by identifying the amount that we require in the current pricing of insurance contracts.

The adjusted fulfilment cash flows approach was used for most non-participating insurance and annuity contracts. The current pricing margin approach was used for most fee-based and pass-through contracts.

The fair value of a group of reinsurance contracts held as at the transition date was measured as the difference between the fair value of the group of underlying insurance contracts without consideration of reinsurance, and the fair value of the group of underlying insurance contracts together with the corresponding group of reinsurance contracts held.

CSM at Transition

The CSM at transition for each group of insurance contracts is the fair value of the contracts less the fulfilment cash flows. The fulfilment cash flows at transition were measured using the IFRS 17 policies described in this Note and Note 2.B. The discount curve was established as at the transition date, and became the locked-in discount curve for the group going forward, as the fair value method was applied.

Details on the impacts on the Consolidated Financial Statements due to the adoption of IFRS 17 are included in Note 2.A.iv.

2.A.ii IFRS 9 Financial Instruments

Summary

During the first quarter, we adopted IFRS 9 Financial Instruments ("IFRS 9"), which includes guidance on the classification and measurement of financial instruments, impairment of financial assets and hedge accounting, and does not require restatement of comparative periods. IFRS 9 replaces IAS 39 Financial Instruments: Recognition and Measurement ("IAS 39"). As a result of the application of IFRS 9, we changed our accounting policies in the areas indicated below, which were effective beginning January 1, 2023. We are permitted, under IFRS 17, to present comparative information on financial assets as if IFRS 9 were applicable during the comparative period ("classification overlay"). We have elected to apply the classification overlay to our financial assets and their comparative period results as if IFRS 9 had been effective since January 1, 2022. Certain comparative period information will continue to be presented in accordance with our previous accounting policies, as indicated below.

Revised Accounting Policies

The material accounting policies used in the preparation of these Consolidated Financial Statements as a result of the adoption of IFRS 9 are summarized below. These policies differ from those included in Note 1 of our 2022 Annual Consolidated Financial Statements. For all other policies not impacted by IFRS 9, refer to Note 1 in our 2022 Annual Consolidated Financial Statements.

Classification of financial assets and financial liabilities

IFRS 9 maintains the IAS 39 classification for financial liabilities. Under IFRS 9, financial liabilities are measured at either amortized cost or FVTPL.

Further details on how we classify and measure our financial assets and financial liabilities and account for the related gains and losses under IFRS 9 are provided below.

Impairment of financial assets

Hedge accounting

Invested Assets

Policies applicable beginning January 1, 2023 (IFRS 9)

Financial Assets Excluding Derivative Financial Instruments (IFRS 9)

Financial assets include cash, cash equivalents and short-term securities, debt securities, equity securities, mortgages and loans, and other financial invested assets.

i) Initial Recognition and Subsequent Measurement

Classification of financial assets

Financial assets are measured at initial recognition at fair value and are classified as and subsequently measured at FVTPL, FVOCI, or amortized cost based on the business model used to manage the financial asset and the contractual cash flow characteristics of the asset. Amortized cost is determined using the effective interest rate method, which is the gross carrying amount less the allowance for ECL. Financial assets are not reclassified subsequent to initial recognition unless the business model used to manage the financial asset has changed.

A financial asset is measured at amortized cost if both of the following conditions are met and the asset is not designated at FVTPL:

•The asset is held within a business model that is held to collect ("HTC"), in which the collection of contractual cash flows from the financial asset is the primary objective and sales are expected to be insignificant or infrequent; and

•The contractual terms of the asset give rise to cash flows that are solely payments of principal and interest ("SPPI") on the principal amount outstanding.

A financial asset is measured at FVOCI if both of the following conditions are met and the asset is not designated at FVTPL:

•The asset is held within a business model that is held to collect and sell ("HTC&S"), in which both the collection of contractual cash flows and the sale of financial assets are integral to achieving the objective of the business model; and

•The contractual terms of the asset give rise, on specified dates, to cash flows that are SPPI.

All financial assets not classified as amortized cost or FVOCI, as described above, are measured at FVTPL. Financial assets at FVTPL include financial assets that are held-for-trading. A financial asset is classified as held-for-trading if it is acquired principally for the purpose of selling in the near term. Cash, cash equivalents and short-term securities are held for trading for the purpose of meeting short-term cash requirements and are measured at FVTPL. On initial recognition, we may also make an irrevocable election to designate a financial asset that would otherwise be measured at amortized cost or FVOCI as measured at FVTPL if the financial asset is managed together with a related financial liability and their performance is evaluated on a fair value basis. Certain debt securities, mortgages and loan instruments that support insurance contract liabilities, which are measured at fair value, have been designated at FVTPL, as doing so significantly reduces measurement inconsistency with the related insurance contract liabilities. These financial assets would otherwise have been measured at FVOCI.

Equity securities are measured at FVTPL, unless the asset is not held for trading purposes and we make an irrevocable election to designate the asset at FVOCI. This election is made on an instrument-by-instrument basis. If such an election is made, the fair value changes, including any associated foreign exchange gains or losses, are recognized in OCI and are not subsequently reclassified to the Consolidated Statements of Operations, including upon disposal. Realized gains and losses are transferred directly to retained earnings upon disposal.

Business model assessment

We determine our business models at the level that best reflects how we manage portfolios of financial assets to achieve our business objectives. Judgment is used in determining our business models, which is supported by relevant, objective evidence including:

•How the economic activities of our businesses generate benefits, for example, through enhancing yields or hedging and how such economic activities are evaluated and reported to key management personnel;

•The significant risks affecting the performance of our businesses, for example, market risk, credit risk, or other risks as described in the Risk Management section of Management’s Discussion and Analysis, and the activities undertaken to manage those risks;

•The frequency, volume, and timing of sales in prior periods, the reasons for the sales and expectations about future sales activity. Information about sales activity is not considered in isolation, but as part of an overall assessment of how our stated objective for managing the financial assets is achieved and how cash flows are realized; and

•The compensation structures for managers of our businesses, to the extent that these are directly linked to the economic performance of the business model.

Our business models include HTC and HTC&S, as described above. Financial assets that are managed on a fair value basis and do not meet the objectives of a HTC or HTC&S business model are measured at FVTPL, such as financial assets that are held for trading.

Assessment of whether contractual cash flows are SPPI

Financial assets held within a HTC or HTC&S business model are assessed to evaluate if their contractual cash flows are comprised of SPPI. SPPI payments are those which would typically be expected from basic lending arrangements, such as interest and basic lending returns, compensation for credit risk and the time value of money, costs associated with holding the financial asset for a period of time, and a profit margin. In making the SPPI assessment, we consider the contractual terms of the instrument, including assessment of whether the timing or amount of the contractual cash flows could change by a contractual term of the financial asset. A prepayment feature is consistent with the SPPI criterion if the prepayment amount substantially represents unpaid amounts of principal and interest on the principal amount outstanding, which may include reasonable compensation for early termination of the contract.

Where the contractual terms introduce exposure to risk or variability of the cash flows that are inconsistent with a basic lending arrangement, the related financial asset is classified as and measured at FVTPL.

Subsequent measurement

Equity securities, debt securities, mortgages and loans that are classified as or designated at FVTPL are recorded at fair value in our Consolidated Statements of Financial Position, and gains or losses, including interest or dividend income and foreign exchange gains and losses, are recognized in Net investment income (loss) in the Consolidated Statements of Operations.

Debt securities, mortgages and loans, and assets supporting Collateralized Loan Obligations ("CLOs") that are classified as FVOCI are recorded at fair value. Interest income, foreign exchange gains (losses), and impairment are recognized in Net investment income (loss) in the Consolidated Statements of Operations. Other gains or losses are recognized in OCI.

Mortgages and loans classified as amortized cost are subsequently measured using the effective interest rate method. Interest income, foreign exchange gains and losses, and impairment are presented in Net investment income (loss) in the Consolidated Statements of Operations.

Other financial invested assets include investments in limited partnerships, segregated funds, and mutual funds that are classified as FVTPL. These financial assets are recorded at fair value, and gains or losses are recognized in Net investment income (loss) in the Consolidated Statements of Operations. Debt securities, mortgages and loans, and Collateralized Loan Obligations included in Other financial invested assets that are classified as FVOCI are recorded at fair value.

Cash equivalents are highly liquid instruments with a term to maturity of three months or less. Cash and cash equivalents are classified as FVTPL and the fair values are assumed to approximate their carrying values, due to their short-term nature or because they are frequently repriced to current market rates. Short-term securities are those that have a term to maturity exceeding three months but less than one year. The fair value of short-term securities is approximated by their carrying amount.

ii) Derecognition

Financial assets are derecognized when our contractual rights to the cash flows of the financial asset have expired, or when we transfer the rights to receive contractual cash flows and substantially all the risks and rewards of owning the financial assets have been transferred. When we neither retain nor transfer substantially all the risks and rewards of ownership, the financial assets are derecognized if control over the financial assets have been relinquished. If we retain control of the financial assets, we continue to recognize the transferred assets to the extent of our continuing involvement.

When financial assets are derecognized, the difference between the carrying amount and the consideration received on the date of derecognition is recognized in Net investment income (loss) in the Consolidated Statements of Operations. For debt securities at FVOCI, the cumulative gains (losses)

CONDENSED NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) Sun Life Financial Inc. Second Quarter 2023 71

previously recognized in OCI are reclassified to Net investment income (loss) in the Consolidated Statements of Operations. For equity investments designated at FVOCI, the cumulative gains (losses) previously recognized in OCI are not reclassified to income.

For financial assets measured at amortized cost in which modifications have resulted in derecognition, the gain (loss) is presented together with impairment losses if the modification was a result of financial difficulties of the borrower. Otherwise, the gain (loss) is presented as Net investment income (loss) in the Consolidated Statements of Operations.

Judgment is applied in determining whether contractual rights to the cash flows from the transferred assets have expired or whether we retain the rights to receive the cash flows on the assets but have assumed an obligation to pay for those cash flows.

iii) Impairment

We establish an allowance for ECL for financial assets not classified or designated at FVTPL. Financial assets measured at amortized cost are presented at their carrying amounts on the Consolidated Statements of Financial Position, which is the gross carrying amount less the allowance for ECL, with changes in the allowance for ECL recognized in Provision for credit losses in Net investment income (loss) in the Consolidated Statements of Operations. The allowance for ECL on financial assets measured at FVOCI does not reduce the carrying amount of the assets in the Consolidated Statements of Financial Position, which remains at fair value. Rather, an amount equal to the allowance for ECL that would arise if the assets were measured at amortized cost is recognized in OCI, with changes in the allowance for ECL recognized in Provision for credit losses in Net investment income (loss) in the Consolidated Statements of Operations.

At the end of each reporting period, we apply a three-stage impairment approach to measure the ECL on financial assets measured at amortized cost or at FVOCI:

•Stage 1: For financial assets that have not experienced a significant increase in credit risk since the date of initial recognition, a loss allowance equal to the credit losses expected to result from default events occurring over the 12 months following the reporting date is recognized.

•Stage 2: For financial assets that have experienced a significant increase in credit risk since the date of initial recognition, a loss allowance equal to the credit losses expected to result from default events occurring over the remaining lifetime of the financial asset is recognized.

•Stage 3: When a financial asset is considered to be credit-impaired, a loss allowance equal to the expected credit losses over the remaining lifetime of the financial asset is recognized. Interest income is calculated based on the carrying amount of the asset, net of the loss allowance.

We monitor all financial assets that are subject to impairment for significant increase in credit risk. In making this assessment, we consider both quantitative and qualitative information that is reasonable and supportable, including historical experience and forward-looking information that is available without undue cost or effort. Additional details about significant increase in credit risk and forward-looking information are provided in Note 6.A.

Modified financial assets

The contractual terms of a financial asset may be modified for a number of reasons, including changing market conditions and other factors not related to a current or potential credit deterioration of the borrower. An existing financial asset whose terms have been modified may be derecognized and the renegotiated asset recognized as a new financial asset at fair value in accordance with the accounting policies in this Note.

If modification does not result in derecognition, the financial asset continues to be subject to the assessment for significant increase in credit risk relative to initial recognition. Expected cash flows arising from the modified contractual terms are considered when calculating the ECL for the modified asset. For loans that were modified while having lifetime ECLs, such loans can revert to having 12-month ECLs if the borrower's financial condition that led to it being identified as credit-impaired are no longer present.

Definition of default

The definition of default used in the measurement of ECL is consistent with the definition of default used for our internal credit risk management purposes. We consider a financial asset to be in default when the issuer is unlikely to meet its credit obligations in full, without recourse action on our part, or when the financial asset is 90 days past due. Our definition of default may differ across financial assets and consider qualitative factors, such as the terms of financial covenants, breaches of such covenants, and other indicators of financial distress, as well as quantitative factors, such as overdue status and non-payment of other obligations under the same issuer. We use internally developed data and those obtained from external sources when assessing default.

Credit-impaired financial assets (Stage 3)

At each reporting date, we assess whether financial assets measured at amortized cost and FVOCI are credit-impaired. A financial asset is credit-impaired when one or more events that have a detrimental impact on the estimated future cash flows of the financial asset have occurred. Evidence of credit-impairment may include indications that the borrower is experiencing significant financial difficulty, probability of bankruptcy or other financial reorganization, as well as a measurable decrease in the estimated future cash flows evidenced by the adverse changes in the payments status of the borrower or economic conditions that correlate with defaults. If a financial asset is credit-impaired, interest income is calculated based on the carrying amount of the asset, which is net of the allowance for ECL, rather than on the gross carrying amount.

Write-off of financial assets

The gross carrying amount of a financial asset, and the related allowance for ECL, is written off (either partially or in full) to the extent that there is no realistic prospect of recovery. This is generally the case when we determine that the borrower does not have assets or sources of income that could generate sufficient cash flows to repay the amounts subject to the write-off. However, financial assets that are written off could still be subject to enforcement activities in order to comply with procedures for recovery of amounts due.

iv) Embedded Derivatives

Under IFRS 9, derivatives embedded in contracts where the host is a financial asset in scope of IFRS 9 are not separated. Instead, the hybrid financial instrument, as a whole, is assessed for classification.

For policies applicable prior to January 1, 2023 under IAS 39 on Impairment, refer to Note 1 of our 2022 Annual Consolidated Financial Statements.

Financial Liabilities

Policies applicable beginning January 1, 2023 (IFRS 9)

Classification and initial measurement

Our financial liabilities, which includes liabilities related to CLOs, are classified and measured at amortized cost, except for financial guarantees and derivative liabilities. Financial guarantees and derivative liabilities are measured at FVTPL. We may also designate certain investment contracts liabilities and third-party interests in consolidated funds at FVTPL on initial recognition, and once designated, the designation is irrevocable. Financial liabilities are designated at FVTPL if doing so either eliminates or significantly reduces accounting mismatch with the supporting assets or that the liabilities and supporting assets are managed together and their performance is evaluated on a fair value basis. The FVTPL designation is available only for those financial liabilities for which a reliable estimate of fair value can be obtained. All other investment contracts are measured at amortized cost using the effective interest rate method.

Subsequent measurement

Financial liabilities classified as or designated at FVTPL are measured at fair value. Any interest expenses and foreign exchange gains (losses) are recognized in Net investment income (loss) in the Consolidated Statements of Operations, unless they arise from derivatives designated as hedging instruments in net investment hedges. For financial liabilities designated at FVTPL, fair value changes attributable to changes in our own credit risk are recorded in OCI, and are not reclassified subsequently to Net investment income (loss) in the Consolidated Statements of Operations. Fair value changes that are not due to changes in our own credit risk are recognized in Net investment income (loss) in the Consolidated Statements of Operations.

Financial liabilities at amortized cost are measured at fair value less transaction costs at initial recognition, and subsequently at amortized cost using the effective interest rate method. Interest expense and foreign exchange gains (losses) are recorded in Net investment income (loss) in the Consolidated Statements of Operations.

Derecognition

We generally derecognize a financial liability when the contractual obligations expire or are discharged or cancelled. We also derecognize a financial liability when the terms are modified and the cash flows of the modified liability are substantially different, in which case a new financial liability based on the modified terms is recognized at fair value. On derecognition of a financial liability, the difference between the carrying amount extinguished and the consideration paid (including any new non-cash assets transferred or liabilities assumed) is recognized in the Consolidated Statements of Operations.

Investment Contract Liabilities (IFRS 9)

Contracts issued by us that do not transfer significant insurance risk, but do transfer financial risk from the policyholder to us, are financial liabilities and are accounted for as investment contracts, unless they have DPF, in which case they are accounted for as insurance contracts (Note 2.A.i). Distinct service components of investment contracts are treated as service contracts.

Investment contract liabilities without DPF are initially recognized at fair value, less transaction costs directly attributable to the issue of the contract, and are subsequently held at amortized cost using the effective interest rate method. Amortization is recorded as a Decrease (increase) in investment contract liabilities in our Consolidated Statements of Operations. Deposits collected from and payments made to contract holders are recorded as changes in our Investment contract liabilities balance in the Consolidated Statements of Financial Position. Investment contract liabilities are derecognized when the obligation of the contract is discharged, cancelled or expired. Investment contract liabilities without DPF include term certain payout annuities in Canada, accumulation annuities and guaranteed investment contracts in Canada, unit-linked products issued in the UK and Hong Kong, and non-unit linked pensions contracts issued in the UK and Hong Kong.

As discussed in Note 2.A.i, investment contracts under which the policyholder bears the risks associated with the underlying investments are classified as Investment contracts for account of segregated fund holders in the Consolidated Statements of Financial Position.

Obligations for Securities Borrowing (IFRS 9)

The obligation for securities borrowing represents our commitment to deliver securities under the short sale program. Under the program, we short sell the securities that we borrowed from a third party. The obligation to return the securities is not recognized in the Consolidated Statements of Financial Position until they are sold, and the risks and rewards of ownership have been transferred. Upon recognition, they are measured at fair value. The securities borrowings are returnable to the lender upon demand or at our discretion.

Transition

The changes in accounting policies resulting from the adoption of IFRS 9 have been applied retrospectively, except as described below:

•The following assessments have been made on the basis of facts and circumstances that existed as at January 1, 2023:

–The determination of the business model within which financial assets are held,

–The designation and revocation of previous designations of certain financial assets and financial liabilities as measured at FVTPL.

•Hedging relationships that were designated under IAS 39 as at December 31, 2022, meet the criteria for hedge accounting under IFRS 9 as at January 1, 2023, and were reflected as continuing hedging relationships.

CONDENSED NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) Sun Life Financial Inc. Second Quarter 2023 73

•If an investment in a debt security had low credit risk as at January 1, 2023, we determined that the credit risk on the asset had not increased significantly since initial recognition.

•We have elected to apply the classification overlay to the financial assets for the comparative period, results are reported as if IFRS 9 had been effective since January 1, 2022.

Further detail on the impacts on the Consolidated Financial Statements due to the adoption of IFRS 9 are included in Note 2.A.iv.

2.A.iii Other Amended International Financial Reporting Standards Adopted in 2023

We adopted the following amendments to IFRS on January 1, 2023. The adoption of these amendments did not have a material impact on our Consolidated Financial Statements:

In May 2021, the IASB issued amendments to IAS 12 Income Taxes ("IAS 12"). The amendments, Deferred Tax related to Assets and Liabilities arising from a Single Transaction, narrow the scope of the recognition exemption in IAS 12 so that it no longer applies to transactions that, on initial recognition, give rise to equal taxable and deductible temporary differences.

In February 2021, the IASB issued amendments to IAS 1 Presentation of Financial Statements ("IAS 1") and IFRS Practice Statement 2 Making Materiality Judgments ("IFRS Practice Statement 2"). The amendments to IAS 1 require companies to disclose their material accounting policy information rather than their significant accounting policies. The amendments to IFRS Practice Statement 2 provide guidance on how to apply the concept of materiality to accounting policy disclosures.

In February 2021, the IASB issued amendments to IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors ("IAS 8"). The amendments clarify how companies should distinguish changes in accounting policies from changes in accounting estimates.

In May 2023, the IASB issued amendments to IAS 12 to give temporary relief from accounting for deferred taxes arising from Pillar Two model rules, which the Organization for Economic Co-operation and Development published in December 2021. The amendments introduce a mandatory temporary exception to the accounting for deferred taxes arising from jurisdictions implementing the global tax rules and disclosure requirements for affected entities to help users better understand an entity’s exposure to Pillar Two income taxes arising from that legislation, particularly before its effective date. The amendments to IAS 12 for disclosure will be effective for annual reporting periods beginning on or after January 1, 2023. We are currently assessing the impact of these amendments on our Consolidated Financial Statements.

2.A.iv Summary of Impact of the New and Amended International Financial Reporting Standards Adopted in 2023

Due to the adoption of IFRS 17 and IFRS 9, key financial items on our Consolidated Statements of Financial position were impacted as follows:

(1) Primarily due to measurement impacts from IFRS 9 classification changes on Mortgages and loans of $4,025.

(2) Due to tax impacts from IFRS 17 and IFRS 9 adoption.

(3) Certain balances, such as Policy loans and amounts related to premiums, that were previously presented separately or included in Other assets and Other liabilities, are included in the assets or liabilities for Insurance contracts issued or Reinsurance contracts held balances under IFRS 17.

(4) Increase primarily due to IFRS 17 remeasurement impacts and a requirement to present Insurance contract assets and Reinsurance contract held liabilities separately from Insurance contract liabilities and Reinsurance contract held assets.

(5) Increase in Insurance contract liabilities and Reinsurance contract held liabilities balances is primarily due to IFRS 17 remeasurement impacts, partially offset by IFRS 17 reclassification impacts. Remeasurement impacts are primarily due to the establishment of CSM of $9.8 billion, the impact of discount rate changes under IFRS 17, and the release of certain reserves held under IFRS 4. Reclassification impacts are primarily offset in Policy loans and Investment contract liabilities.

(6) Certain contracts previously included in Insurance contract liabilities under IFRS 4 are reclassified to Investment contract liabilities under IFRS 17.

(7) Consists of a $4.4 billion reduction to Shareholders' equity and a $1.5 billion reduction to Equity in the participating account.

Impact of applying the classification overlay on January 1, 2022

As permitted by IFRS 17 and IFRS 9, we have elected to apply the classification and measurement requirements of IFRS 9 to remeasure all financial assets held in comparative periods, including those that were derecognized during that period. The classification and measurement of these financial assets were based on our expected business model as at January 1, 2022. For financial assets in which the impairment requirements of IFRS 9 applies, we have elected to continue presenting the loss allowance that was determined in accordance with IAS 39.

The impact of applying the classification overlay on the classification and measurement of financial assets for the comparative years are presented below:


	Classification Category		IAS 39						IFRS 9
Financial instrument	IAS 39	IFRS 9	As at December 31, 2021			Impact of classification overlay			As at January 1, 2022
Assets impacted by the classification overlay:
Debt securities	AFS	FVTPL		$	125		$	—		$	125	(1)
Debt securities	AFS	FVOCI		12,604			—			12,604
Debt securities	FVTPL	FVOCI		3,549			—			3,549		(2)
Equity securities	AFS	FVTPL		1,575			—			1,575		(3)

Mortgages and loans	Loans and receivables	FVTPL		47,772			4,015			51,787		(4)

Mortgages and loans	Loans and receivables	Amortized cost		2,326			—			2,326		(6)
Other financial invested assets	AFS	FVTPL		781			—			781		(3)
Other financial invested assets	Amortized cost	FVOCI		1,865			(10)			1,855		(7)
Assets not impacted by the classification overlay:
Derivative assets	FVTPL	FVTPL		1,583			—			1,583
Other financial invested assets	FVTPL	FVTPL		4,435			—			4,435
Cash, cash equivalents and short-term securities	FVTPL	FVTPL		12,278			—			12,278
Debt securities	FVTPL	FVTPL		72,449			—			72,449
Equity securities	FVTPL	FVTPL		7,538			—			7,538
Total				$	170,474		$	4,025		$	174,499

(1) Certain debt securities classified as AFS under IAS 39 are reclassified to FVTPL under IFRS 9, primarily because doing so can eliminate or significantly reduce an accounting mismatch.

(2) Certain debt securities previously designated at FVTPL under IAS 39 are reclassified to FVOCI under IFRS 9 as they are managed within a business model of collecting contractual cash flows and selling the financial assets, and pass the SPPI test.

(3) Certain equity securities and other financial invested assets were classified as AFS under IAS 39 are reclassified to FVTPL under IFRS 9 and we have not elected to designate them at FVOCI.

(4) Certain mortgages and loans classified as loans and receivables under IAS 39 are reclassified to FVTPL under IFRS 9, primarily because doing so can eliminate or significantly reduce an accounting mismatch. The carrying value of these mortgages and loans was adjusted to reflect their fair value with the difference recorded in retained earnings.

(5) Certain mortgages and loans classified as loans and receivables under IAS 39 are reclassified to FVOCI under IFRS 9 as they are held within a business model of collecting contractual cash flows and selling the financial assets, and pass the SPPI test.

(6) Certain mortgages and loans classified as loans and receivables under IAS 39 are reclassified to amortized cost under IFRS 9 as they are held within a business model of collecting contractual cash flows, and pass the SPPI test.

(7) Under IAS 39, CLOs within other financial invested assets were classified as amortized cost. These assets are managed within a business model of collecting contractual cash flows and selling the financial assets, and pass the SPPI test. Accordingly, we have reclassified these other financial invested assets from amortized cost to FVOCI under IFRS 9.

The classification overlay was applied as at January 1, 2022, with a post-tax impact of $2,873 to opening retained earnings and $(116) to AOCI. Equity in the participating account increased by a post-tax amount of $397. Our accounting policies for the classification of financial instruments under IFRS 9 are set out in Note 2.A.ii. The application of those accounting policies resulted in the reclassifications presented in the table above.

Impact of IFRS 9 adoption on January 1, 2023

Classification of financial assets and financial liabilities

The following table summarizes the classification and measurement impact of IFRS 9 as at January 1, 2023, including any reclassification and remeasurement changes from how assets were measured using the classification overlay. Reclassifications represent movements of the carrying amount of financial assets and financial liabilities whose classifications have changed as a result of IFRS 9. Remeasurement represents changes in the carrying amount of the financial assets and financial liabilities due to changes in their measurement.

Total financial assets				$	157,035		$	—		$	19		$	157,054

(1) Amounts for the year ended December 31, 2022 were adjusted to reflect application of the classification overlay, the recognition of unfunded commitments on FVTPL fixed income assets and the impact of enhancements to our fair value methodology for private fixed income assets. The enhancements increased observability of inputs to the fair valuation of private fixed income assets and resulted in a decrease of $634 in the carrying value of our private fixed income assets as at December 31, 2022. The recognition of unfunded commitments resulted in a decrease of $98 in the carrying value of our mortgages and loans as at December 31, 2022.

(2) Certain financial assets were reclassified between classification categories upon the adoption of IFRS 17 and IFRS 9 on January 1, 2023. The reclassifications were primarily driven by asset rebalancing between segments where level of sensitivity to interest rates resulted in the designation of certain fixed income assets at FVTPL or a reclassification from FVTPL to FVOCI.

(3) We adopted impairment requirements under IFRS 9 on January 1, 2023. Remeasurement primarily reflects the difference between IAS 39 incurred loss allowance and IFRS 9 allowance for ECL that affect carrying value. Refer to the Impairment of financial assets table below for remaining adjustments that did not affect carrying value.

(4) The IAS 39 classification category for financial asset balances as at December 31, 2022 can be referenced in the table above describing the impact of the classification overlay.

Our financial liabilities were not significantly impacted by the adoption of IFRS 9 on January 1, 2023. Segregated fund contracts and supporting assets were also not significantly impacted by the adoption of IFRS 9 on January 1, 2023, as they maintained a FVTPL classification. The post-tax amounts recognized in opening retained earnings and AOCI on January 1, 2023, as a result of the adoption of IFRS 9, were $(553) and $553, respectively.

Items previously designated at FVTPL

2.B Additional Disclosures

IFRS 17 and IFRS 9 require enhanced disclosures for insurance contracts and financial instruments. These disclosures are included primarily in Notes 5, 6, 7 and 12 of our Interim Consolidated Financial Statements. The disclosures in this section are being added to our Interim Consolidated Financial Statements to provide additional context during the first year of adoption of IFRS 17 and IFRS 9. The majority of these disclosures would otherwise only be reported by us in our Annual Consolidated Financial Statements. These bridging disclosures are limited to those items or balances that have had material recognition, classification, measurement or presentation changes upon adoption of IFRS 17 and IFRS 9.

Methods and Assumptions

General

A group of insurance contracts is measured as the total of FCF, which is the present value of future cash flows plus the risk adjustment for

The CSM represents the unearned profit that will be recognized as insurance contract services are provided.

The methods and assumptions used in the measurement of insurance contracts are reviewed regularly and are subject to external actuarial peer review.

Current Discount Rates

Current discount rates for cash flows that do not vary based on returns on underlying items

The currency of cash flows is reflected by using different discount curves for different currencies.

Liquidity is reflected by adding a liquidity premium to risk-free discount rates that is consistent with the liquidity characteristics of the insurance contracts. The liquidity premium in the observable period is based on the liquidity premium on assets with similar liquidity characteristics, which is estimated from the spread inherent in current market yields less a deduction for expected and unexpected credit losses. The deduction for expected and unexpected credit losses is estimated using historical rating agency data and current market conditions, and varies by asset type, quality, and duration. The liquidity premium in the unobservable period is interpolated between the last observable liquidity premium and an ultimate liquidity premium (at year 70) specific to liquid or illiquid contracts. See Note 7.A for further details, which provides a weighted average summary of the discount curves used to present value cash flows for all major products that do not vary based on the returns on underlying items.

Scenario Testing

CONDENSED NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) Sun Life Financial Inc. Second Quarter 2023 79

Risk Adjustment for Non-Financial Risk

•The statistical credibility of our experience is too low to be the primary source of data for choosing the assumption;

•Future experience is difficult to estimate;

•The cohort of risks lacks homogeneity;

•Operational risks adversely impact the ability to estimate the assumption; or

•Past experience may not be representative of future experience and the experience may deteriorate.

Margins are generally stable over time and are revised only to reflect changes in the level of uncertainty in the assumptions. Our margins tend to be at mid-range.

The RA for insurance contracts issued and reinsurance contracts held corresponds to a confidence level of approximately 80-85% overall.

Contractual Service Margin

The initial and subsequent measurement of CSM is described in Note 2.A.i. Additional detail about certain components of the measurement of CSM is provided below.

Interest accretion

For insurance contracts measured using the VFA, there is no accretion of interest. Rather, the CSM is adjusted by the change in our share of the fair value of underlying items.

Changes in FCF relating to future service

Changes in FCF relating to future service include (Liability for Remaining Coverage only):

•All changes related to investment component payments (including current period payments);

•Changes arising from changes in assumptions used to derive the present value of future cash flows - limited to non-financial assumptions for insurance contracts measured using the GMA;

•Changes in future cash flows arising from claims in the current period; and

CSM amortization

The amount of CSM recognized as insurance revenue in each period to reflect the insurance contract services provided for a group of contracts in the period is determined by:

•Identifying the total coverage units in the group (for services in current and future periods) – based on the quantity of insurance contract services;

•Recognizing in insurance revenue the amount allocated to coverage units provided in the period.

80 Sun Life Financial Inc. Second Quarter 2023 CONDENSED NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

For reinsurance contracts held, CSM amortization reflects the services received in the period.

2.B.iii Insurance Risk

The impact on CSM is attributable to insurance contracts measured using the GMA and VFA. For insurance contracts measured using the GMA, the impact flows through the CSM at locked-in discount rates. For insurance contracts measured using the VFA, the impact flows through the CSM at current discount rates.

The impact on net income is attributable to any portion of the sensitivities for insurance contracts measured under GMA and VFA that cannot be absorbed by CSM, the full impact for insurance contracts measured under the PAA, and the difference in impact between locked-in and current discount rates for insurance contracts measured using the GMA. If current discount rates are higher than locked-in rates, this generally results in a favourable impact to net income from contracts measured using the GMA.



As at December 31, 2022	Potential impact on CSM (pre-tax)		Potential impact on net income / equity (post-tax)
Sensitivities(1)		Insurance contracts issued	Net of reinsurance contracts held						Insurance contracts issued		Net of reinsurance contracts held

3. Acquisitions and Other

SLF of Canada UK Limited Disposition

On August 4, 2022, we entered into an agreement to sell SLF of Canada UK Limited ("Sun Life UK"). Effective April 3, 2023, we completed the sale of Sun Life UK to Phoenix Group Holdings plc. Sun Life UK manages life and pension policies as well as payout annuities blocks for UK Clients. Sun Life UK was closed to new sales and had operated as a run-off business since 2001. We retain our economic interest in the payout annuities business after the sale through a reinsurance treaty that will be reported within our U.S. segment.

During the quarter, a gain of $12 on the sale of the business was recognized in Total net income on the Consolidated Statements of Operations. The disposal is included within our Corporate business segment. Prior to the completion of the sale, we had recorded an impairment charge of $170 pertaining to goodwill that was written off during the third quarter of 2022.

The details of the disposition are summarized as follows:


As at April 3, 2023
Cash consideration	$	418
Less: Net assets	(359)
Less: Foreign currency translation, transaction costs, and other adjustments	(47)
Total gain recognized in Total net income in current period	$	12

DentaQuest

On June 1, 2022, we acquired DentaQuest, the second-largest provider of dental benefits in the United States by membership, for $3,267 (US$2,584). Total consideration for the 100% acquisition of DentaQuest was paid with cash of $3,267, and primarily comprised of goodwill and intangibles, including contractual relationships, software, and brand. DentaQuest is reported in the Dental CGU of our U.S. business segment. The acquisition of DentaQuest aligns to our business strategy of being a leader in health and group benefits, with an increasing focus on health.

The fair values of the identifiable assets and liabilities acquired were:


As at June 1, 2022
Intangible assets	$	1,074
Net assets	255
Deferred tax liabilities	(189)
Total identifiable net assets at fair value	1,140

Goodwill arising on acquisition(1)	2,127
Total consideration	$	3,267

(1) Goodwill primarily reflects expected synergies from the combination of DentaQuest and our existing Dental and Vision business within the U.S. Group Benefits business, as well as the future growth potential of the DentaQuest business. Goodwill is not tax deductible.

The fair value of the identifiable assets and liabilities were subject to refinement and have been adjusted.

Advisors Asset Management Inc.

On February 1, 2023, we completed the acquisition of a 51% interest, on a fully diluted basis, in Advisors Asset Management Inc. ("AAM"), as well as the ability to acquire the remaining interest in the future. AAM is a leading independent U.S. retail distribution firm, and forms part of our Asset Management business segment. AAM will become the U.S. retail distribution arm of SLC Management. Consideration included $248 (US$187) in cash.

The fair values of the identifiable assets and liabilities acquired were:


As at February 1, 2023
Intangible assets and Goodwill	$	515
Net assets	44
Deferred tax liability	(100)
Total identifiable net assets at fair value	459
Non-controlling interest(1)	(211)
Total consideration	$	248

(1) We have elected to measure non-controlling interest ("NCI") at fair value for this acquisition. The fair value was determined by calculating the proportionate share of the present value of future cash flows relating to NCI. Significant assumptions inherent in the valuation of NCI include the estimated after-tax cash flows expected to be received and an assessment of the appropriate discount rate.

The fair values of the identifiable assets and liabilities are subject to refinement and may be retroactively adjusted to reflect new information obtained about facts and circumstances that existed at the acquisition date during the measurement period.

86 Sun Life Financial Inc. Second Quarter 2023 CONDENSED NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

AAM minority shareholders also have the option to require us to purchase their shares ("put option") in 2028. We have a call option to acquire the remaining outstanding shares held by these minority shareholders commencing in 2028. The fair value of the put option liability was recognized in Other financial liabilities and any excess over the carrying amounts arising from transactions relating to non-controlling shareholders was recorded as a reduction to Retained earnings. Any changes to the carrying value of the financial liability after the acquisition date will be recognized in the Consolidated Statements of Operations.

Other

On January 20, 2023, we announced our entry into a 15-year exclusive bancassurance partnership with Dah Sing Bank, Limited. This is our first exclusive bancassurance partnership in Hong Kong and will be a valuable complement to our existing network of insurance advisors. We will pay an amount of approximately $260 for this exclusive arrangement, with ongoing variable payments to Dah Sing Bank, Limited based on the success of the partnership.

Effective February 1, 2023, we completed the sale of our sponsored markets business to Canadian Premier Life Insurance Company. Our sponsored markets business includes a variety of association & affinity, and group creditor clients. We disposed of assets of approximately $638 and liabilities of approximately $638. Total consideration received consisted of cash consideration of $98 and contingent consideration of $25. During the first quarter of 2023, we recorded a pre-tax gain on the sale of the business of $102 in Other income on the Consolidated Statements of Operations. The gain on the sale of the business net of goodwill disposed, transaction costs and taxes is $65.

4. Segmented Information

We have five reportable business segments: Canada, U.S., Asset Management, Asia, and Corporate. These business segments operate in the financial services industry and reflect our management structure and internal financial reporting. Asset Management includes the results of our MFS and SLC Management business units. Corporate includes the results of our UK business unit and our Corporate Support operations, which include run-off reinsurance operations, as well as investment income, expenses, capital and other items not allocated to our other business groups. Effective the second quarter of 2023, we completed the sale of our UK Business unit. We have retained our economic interest in the annuity business via a reinsurance arrangement that will be reported under the U.S. reportable segment on a prospective basis.

Revenues from our business segments are derived primarily from life and health insurance, investment management and annuities, and mutual funds. Revenues not attributed to the strategic business units are derived primarily from Corporate investments and earnings on capital. Transactions between segments are executed and priced at an arm's-length basis in a manner similar to transactions with third parties.

The expenses in each business segment may include costs or services directly incurred or provided on their behalf at the enterprise level. For other costs not directly attributable to one of our business segments, we use a management reporting framework that uses assumptions, judgments, and methodologies for allocating overhead costs and indirect expenses to our business segments.

Intersegment transactions consist primarily of internal financing agreements which are measured at fair values prevailing when the arrangements are negotiated. Intersegment investment income consists primarily of interest paid by U.S. to Corporate. Intersegment fee income is primarily asset management fees paid by our business segments to Asset Management. SLC Management collects fee income and incurs the operational expenses associated with the management of the general fund assets. Intersegment transactions are eliminated in the Consolidation adjustments column in the following tables.

Management considers its external Clients to be individuals and corporations. We are not reliant on any individual Client as none is individually significant to our operations.

Collateralized Loan Obligations

Crescent, a subsidiary within our Asset Management business segment, issues and manages CLOs. Each CLO is a special purpose vehicle that owns a portfolio of investments, consisting primarily of senior secured loans, and issues various tranches of senior and subordinated notes to third parties for the purpose of financing the purchase of those investments. Assets of the special purpose vehicle are included in Other financial invested assets and the associated liabilities are included in Other liabilities in our Consolidated Statements of Financial Position. See Note 8 for the associated liabilities for the CLOs.

As at June 30, 2023, the carrying value of the assets supporting the CLOs are $3,006 (December 31, 2022 — $2,880), which consists of cash and accounts receivable of $172 (December 31, 2022 — $292) and loans of $2,834 (December 31, 2022 — $2,588). These underlying loans are mainly below investment grade. Our maximum contractual exposure to loss related to the CLOs is limited to our investment of $172 (December 31, 2022 — $159) in the most subordinated tranche.

5.A.iii Fair Value Hierarchy

The fair value methodologies and assumptions for assets and liabilities carried at fair value, as well as disclosures on unobservable inputs, sensitivities and valuation processes for Level 3 assets can be found in Note 5 of our 2022 Annual Consolidated Financial Statements, and as updated below.

Fair Value Methodologies and Assumptions

Collateralized loan obligations

The fair value of underlying assets within our CLOs is determined primarily using observable market inputs, such as quoted prices for similar assets in active markets and other observable market data.

Mortgages and loans

The fair value of mortgages and loans is determined by discounting the expected future contractual cash flows using a current market interest rate applicable to financial instruments with a similar yield, credit quality, and maturity characteristics. Valuation inputs typically include benchmark yields and risk-adjusted spreads from current internal lending activities or loan issuances. Beginning in the fourth quarter of 2022, valuation inputs also include external lending activities or loan issuances from both public and private markets, enhancing the market observability of inputs. The risk-adjusted spreads are determined based on the borrower’s credit and liquidity, as well as term and other loan-specific features.

Unobservable Inputs and Sensitivity for Level 3 Assets

Our mortgages and loans, categorized in Level 3, are included in Mortgages and loans – FVTPL and Mortgages and loans – FVOCI in the Level 3 roll forward table, and Mortgages and loans – amortized cost in Note 5.A.i. The fair value of these mortgages and loans is determined by using the discounted cash flow methodology. The key unobservable inputs used in the valuation of mortgages and loans as at June 30, 2023 include credit spreads and liquidity adjustments. The credit spread is the difference between the instrument yield and the benchmark yield. The benchmark yield is determined by matching each asset by geography, sector, rating and maturity to a matrix comprised of spreads of publicly available corporate bonds. In some cases, a liquidity premium or discount may be applied if recent private spreads differ from public spreads. The credit spreads range from 0.50% to 3.50%. The liquidity adjustments range from a discount of 0.50% to a premium of 1.00%. Changes in the fair value of mortgages and loans are negatively correlated with changes in credit spread and liquidity adjustments.

Valuation Process for Level 3 Assets

The fair value of mortgages and loans is based on an internal discounted cash flow model, subject to detailed review and validation to ensure overall reasonability.

Our assets and liabilities that are carried at fair value on a recurring basis by hierarchy level are as follows:

(1) Mortgages and loans were classified as amortized cost under IAS 39 for the year ended December 31, 2021. On application of the classification overlay on January 1, 2022, mortgages and loans are measured at FVTPL or FVOCI. During the fourth quarter of 2022, we had a change to our fair value methodology for mortgages and loans that constitutes a change in estimate as at December 31, 2022. Levelling changed from Level 3 to Level 2 as a result of applying fair value enhancements in valuing mortgages and loans supporting insurance liabilities. See Mortgages and loans section above for further details.

(2) Other financial invested assets - FVOCI reflects assets related to CLOs.

For transfers out of Level 3 during the reporting period, the change in fair value for the period is excluded from the table above.

(3) Investment properties included in net income is comprised of fair value changes on investment properties of $(123) and $(134) for the three and six months ended June 30, 2023, respectively (June 30, 2022 — $205 and $585, respectively), net of amortization of leasing commissions and tenant inducements of $10 and $16 for the three and six months ended June 30, 2023, respectively (June 30, 2022 — $6 and $22, respectively). As at June 30, 2023, we have used assumptions that reflect known changes in the property values including changes in expected future cash flows.

(4) Transfers into Level 3 occur when the inputs used to price the assets and liabilities lack observable market data, and as a result, no longer meet the Level 1 or 2 definitions at the reporting date. Transfers out of Level 3 occur when the pricing inputs become more transparent and satisfy the Level 1 or 2 criteria and are primarily the result of observable market data being available at the reporting date, thus removing the requirement to rely on inputs that lack observability.

(5) Foreign currency translation relates to the foreign exchange impact of translating Level 3 assets and liabilities of foreign subsidiaries from their functional currencies to Canadian dollars.

(6) Mortgages and loans were classified as amortized cost under IAS 39 for the year ended December 31, 2021. On application of the classification overlay on January 1, 2022, mortgages and loans are measured at FVTPL or FVOCI. During the fourth quarter of 2022, we had a change to our fair value methodology for mortgages and loans that constitutes a change in estimate as at December 31, 2022. Levelling changed from Level 3 to Level 2 as a result of applying fair value enhancements in valuing mortgages and loans supporting insurance liabilities. See Mortgages and loans section above for further details.

5.E Mortgage Securitization

We securitize certain insured fixed rate commercial mortgages as described in Note 5 of our 2022 Annual Consolidated Financial Statements.

The carrying value and fair value of the securitized mortgages as at June 30, 2023 are $1,879 and $1,747, respectively (December 31, 2022 — $1,926 and $1,793, respectively). The carrying value and fair value of the associated liabilities as at June 30, 2023 are $2,119 and $1,974, respectively (December 31, 2022 — $2,158 and $2,018, respectively). The carrying value of securities in the principal reinvestment account (''PRA'') as at June 30, 2023 is $241 (December 31, 2022 — $244). There are $nil cash and cash equivalents in the PRA as at June 30, 2023 (December 31, 2022 — $nil).

The fair value of the secured borrowings from mortgage securitization is based on the methodologies and assumptions for asset-backed securities described in Note 5 of our 2022 Annual Consolidated Financial Statements. The fair value of these liabilities is categorized in Level 2 of the fair value hierarchy as at June 30, 2023 and December 31, 2022.

6. Financial Instrument Risk Management

The significant risks related to financial instruments are credit risk, market risk (including equity risk, real estate risk, interest rate and spread risk, foreign currency risk, and inflation risk) and liquidity risk.

Our financial instruments risk management policies and procedures are described in our Management’s Discussion and Analysis ("MD&A") as at June 30, 2023 and December 31, 2022. The text and tables in the Risk Management section of the MD&A represent part of our disclosures on credit, market and liquidity risks and include a description of how we measure our risk and our objectives, policies and methodologies for managing these risks. Therefore, the text and tables in our MD&A form an integral part of these Consolidated Financial Statements.

We use derivative instruments to manage market risks related to equity market, interest rate and currency fluctuations and in replication strategies for permissible investments. We do not engage in speculative investment in derivatives. The gap in market sensitivities or exposures between liabilities and supporting assets is monitored and managed within defined tolerance limits, by using derivative instruments, where appropriate. We use models and techniques to measure the effectiveness of our risk management strategies.

6.A Impairment of financial assets

Refer to accounting policies in Note 2.A.ii.

Policies after January 1, 2023 (IFRS 9)

Significant increase in credit risk

The assessment of significant increase in credit risk requires judgment. We assign counterparties a relevant internal credit risk rating grade depending on their credit quality. Changes in borrower-specific internal risk ratings is a primary indicator of significant increase in credit risk.

At each reporting date, movements between Stage 1 and Stage 2 are determined based on whether an instrument’s internal rating as at the reporting date has increased (decreased) significantly relative to the date it was initially recognized. We assess whether there has been a significant increase in credit risk for exposures since initial recognition by comparing the risk of default occurring over the remaining expected life from the reporting date and the date of initial recognition. The assessment considers borrower-specific quantitative and qualitative information without consideration of collateral, and the impact of forward-looking macroeconomic factors. Unless identified at an earlier stage, the credit risk of financial assets is deemed to have increased significantly when more than 30 days past due or moved to Watch List status and such assets are automatically migrated to Stage 2. Exposures are classified as "Watch List" when there is a moderate deterioration in credit quality, but the full payment of principal and interest is still expected to be collected, or there is an increased possibility of the exposure being impaired in the near term. No impairment charge is recorded for unrealized losses on assets related to these debtors.

Incorporation of forward-looking information

The measurement of ECL for each stage and the assessment of significant increase in credit risk considers future events and economic conditions. The estimation and application of forward-looking information requires significant judgment.

100 Sun Life Financial Inc. Second Quarter 2023 CONDENSED NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

The probability of default ("PD"), loss given default ("LGD") and exposure at default ("EAD") inputs used to estimate allowance for ECL are modelled based on the macroeconomic variables (or changes in macroeconomic variables) that are most closely correlated with credit losses in the relevant portfolio.

Our estimation of ECL is a discounted probability-weighted estimate that considers a minimum of three future macroeconomic scenarios (base case, upside and downside) and probability weights are attributed to each scenario. All scenarios considered are applied to all portfolios subject to ECL with the same probabilities. Our assessment of significant increase in credit risk is based on changes in internal rating as at the reporting date.

We subscribe to Moody's Analytics economic forecasting services and leverage its forward-looking macroeconomic information to model ECL.

Measurement of ECL

ECL is measured as the probability-weighted present value of expected cash shortfalls expected to result from defaults over the relevant time horizon, which is the maximum contractual period over which we are exposed to credit risk, including consideration of prepayments, and extensions.

The mechanics of the ECL calculations are outlined below and the key elements are as follows: PD, LGD, and EAD.

The PD is an estimate of the likelihood of default over a given time horizon. It is estimated as at a point in time based on historical losses, along with consideration of economic scenarios and forward-looking information.

LGD is the magnitude of the likely loss if there is a default at a given time. It is based on the difference in the present values of the contractual cash flows due and those that the lender would expect to receive, including from the realization of any collateral (net of directly attributable costs).

EAD represents the expected exposure in the event of a default. We derive the EAD from the current exposure to the counterparty and potential changes to the current amount allowed under the contract, including amortization, and prepayments.

An ECL estimate is produced for each individual exposure. Relevant parameters are modelled on a collective basis using portfolio segmentation that allows for appropriate incorporation of forward-looking information. To reflect other characteristics that are not already considered through modelling, expert credit judgment can be exercised in determining the final ECL.

Qualitative adjustments or overlays

The inputs and models used for calculating ECL may not always capture all characteristics of the market at the date of the financial statements. This could be a case where a major event occurs close to the reporting date, so that the potential effects are not appropriately captured in the models and inputs. To reflect this, qualitative adjustments or overlays are occasionally made as temporary adjustments when such differences are material.

Mortgages and Loans by Credit Rating

The credit quality of mortgages and loans is evaluated internally through regular monitoring of credit-related exposures. We use judgment and experience to determine what factors should be considered when assigning an internal credit rating, which is validated through the use of credit scoring models, to a particular mortgage or corporate loan. The internal credit ratings reflect the credit quality of the borrower as well as the value of any collateral held as security.

6.B Market Risk

Risk Description

We are exposed to market risk, which is defined as the risk that the value or future cash flows of insurance and investment contract liabilities or financial assets will fluctuate because of changes or volatility in market prices. Market risk includes equity, interest rate and spread, real estate, foreign currency, and inflation risks.

Market Risk Management Governance and Control

We employ a wide range of market risk management practices and controls as outlined below:

•Market risk governance practices are in place, including independent monitoring and review and reporting to senior management and the Risk Committee.

•Risk appetite limits have been established for equity, interest rate, credit spread, real estate and foreign currency risks.

•Income and regulatory capital sensitivities are monitored, managed and reported against pre-established risk limits.

•Comprehensive asset-liability management and hedging policies, programs and practices are in place.

•Regulatory solvency requirements include risk-based capital requirements and are monitored regularly.

•Product Design and Pricing Policy requires a detailed risk assessment and pricing provisions for material risks.

•Stress-testing techniques, such as FCT, are used to measure the effects of large and sustained adverse market movements.

•Insurance contract liabilities are established in accordance with Canadian actuarial standards of practice and International Financial Reporting Standards.

•Internal capital targets are established at an enterprise level to cover all risks and are above minimum regulatory and supervisory levels. Actual capital levels are monitored to ensure they exceed internal targets.

Specific market risks and our risk management strategies are discussed below in further detail.

6.B.i Equity Risk

We generate revenue in our asset management businesses and from certain insurance and annuity contracts where fees are levied on account balances that are affected directly by equity market levels. Accordingly, we have further exposure to equity risk as adverse fluctuations in the market value of such assets will result in corresponding adverse impacts on revenue and income. In addition, declining and volatile equity markets may have a negative impact on sales and redemptions (surrenders) in these businesses, and this may result in further adverse impacts on net income.

6.B.ii Interest Rate and Credit Spread Risk

Interest rate and spread risk includes the potential for financial loss arising from changes in the value of insurance and investment contract liabilities and financial assets due to changes or volatility in interest rates or spreads. In practice, when asset cash flows and the policy obligations they support are not matched, this may result in the need to either sell assets to meet policy payments and expenses or reinvest excess asset cash flows in unfavourable interest rate or credit spread environments. This risk is managed in our asset-liability management program.

Our primary exposure to interest rate and spread risk arises from insurance and investment contracts that contain guarantees in the form of minimum crediting rates, maximum premium rates, settlement options, guaranteed annuitization options and minimum benefits. If investment returns fall below guaranteed levels, we may be required to increase liabilities or capital in respect of these contracts. The guarantees attached to these products may be applicable to both past premiums collected and future premiums not yet received. Segregated fund contracts provide benefit guarantees that are linked to underlying fund performance and may be triggered upon death, maturity, withdrawal or annuitization. We are also exposed to interest rate risk through guaranteed annuitization options included primarily in retirement contracts and pension plans. These embedded options give policyholders the right to convert their investment into a pension on a guaranteed basis, thereby exposing us to declining long-term interest rates as the annuity guarantee rates come into effect. The cost of providing these guarantees is uncertain and depends upon a number of factors including the level and concentration of the guarantees relative to prevailing interest rates, credit spreads, non-fixed income returns, and policyholder behaviour. Exposure to guarantees is managed within our risk appetite limits through our asset-liability management program, which may include the use of hedging strategies utilizing interest rate derivatives such as interest rate floors, swaps, futures and swaptions. The impact of these guarantees on net income are included in the disclosed market risk sensitivities.

Declines in interest rates or narrowing spreads can result in compression of the net spread between interest earned on investments and interest credited to policyholders. Declines in interest rates or narrowing spreads can also result in increased asset calls, mortgage prepayments, and net reinvestment of positive cash flows at lower yields, and therefore adversely impact our profitability and financial position. Negative interest rates may additionally result in losses on our cash and short-term deposits and low or negative returns on our fixed income assets impacting our profitability. In contrast, increases in interest rates or a widening of credit spreads can reduce market values of fixed income assets, which may lead to lower capital or losses in the event of the liquidation of assets prior to maturity.

CONDENSED NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) Sun Life Financial Inc. Second Quarter 2023 105

Significant changes or volatility in interest rates or spreads could have a negative impact on sales of certain insurance and annuity products, and adversely impact the expected pattern of redemptions (surrenders) on existing policies. Increases in interest rates or widening credit spreads may increase the risk that policyholders will surrender their contracts, potentially forcing us to liquidate assets at a loss. While we have established hedging programs in place and our insurance and annuity products often contain surrender mitigation features, these may not be sufficient to fully offset the adverse impact of changes in interest rates or spreads.

We also have direct exposure to interest rates and spreads from investments supporting other general account liabilities, surplus and employee benefit plans. Lower interest rates or a narrowing of spreads will result in reduced investment income on new fixed income asset purchases. Conversely, higher interest rates or wider spreads will reduce the value of our existing assets. These exposures fall within our risk-taking philosophy and appetite and are therefore generally not hedged.

6.B.iii Real Estate Risk

estate price risk may arise from external market conditions, inadequate property analysis, inadequate insurance coverage, inappropriate real estate appraisals, or from environmental risk exposures. We hold real estate investments that support general account liabilities and surplus, and fluctuations in value will affect our net income. A material and sustained increase in interest rates may lead to deterioration in real estate values.

6.B.iv Market Risk Sensitivities

We use a variety of methods and measures to manage and quantify our market risk exposures. These include duration and key rate duration management, convexity measures, cash flow gap analysis, scenario testing, and sensitivity testing of earnings and regulatory capital ratios.

The measurement of liabilities and assets are affected by the level of equity market performance, interest rates, credit and swap spreads and other market risk variables. The following sections set out the estimated immediate impact on, or sensitivity of, our net income and OCI to certain instantaneous changes in market variables as at June 30, 2023 and December 31, 2022.

The estimated sensitivities in the tables below reflect the impact of market movements on insurance contracts and investment contracts, assets backing insurance contracts, assets backing investment contracts, assets backing the surplus segment, and seed investments in our asset management subsidiaries.

Net income sensitivities to equity and real estate market movements are driven primarily by changes in the value of investments backing general account liabilities and surplus. Net income sensitivities to interest rates and spreads are driven by the net impact on liabilities and the assets backing them. Lower interest rates or a narrowing of spreads will result in increased liabilities for insurance contracts, offset by increased values of the assets backing general account liabilities. Higher interest rates or a widening of spreads will result in decreased liabilities for insurance contracts, offset by decreased values of the assets backing general account liabilities.

OCI sensitivities are impacted by changes in the market value of assets classified as FVOCI. The market value of FVOCI fixed income assets, which are held primarily in our surplus and investment contract segments, increases with lower interest rates or a narrowing of spreads, and decreases with higher interest rates or a widening of spreads.

Refer to Additional Cautionary Language and Key Assumptions Related to Sensitivities in this section for important additional information regarding these estimates.

6.B.v Foreign Currency Risk

Foreign currency risk is the result of mismatches in the currency of our assets and liabilities (inclusive of capital), and cash flows. This risk may arise from a variety of sources such as foreign currency transactions and services, foreign currency hedging, investments denominated in foreign currencies, investments in foreign subsidiaries and net income from foreign operations. Changes or volatility in foreign exchange rates, including a change to currencies that are fixed in value to another currency, could adversely affect our net income.

As an international provider of financial services, we operate in a number of countries, with revenues and expenses denominated in several local currencies. In each country in which we operate, we generally maintain the currency profile of assets to match the currency of liabilities and required capital. This approach provides an operational hedge against disruptions in local operations caused by currency fluctuations. Foreign currency derivative contracts such as currency swaps and forwards are used as a risk management tool to manage the currency exposure in accordance with our Asset Liability Management Policy. As at June 30, 2023 and December 31, 2022, the Company did not have a material foreign currency risk exposure.

Changes in exchange rates can affect our net income and surplus when financial results in functional currencies are translated into Canadian dollars. Net income earned outside of Canada is generally not currency hedged and a weakening in the local currency of our foreign operations relative to the Canadian dollar can have a negative impact on our net income reported in Canadian currency. A strengthening in the local currency of our foreign operations relative to the Canadian dollar would have the opposite effect. Regulatory capital ratios could also be impacted by changes in exchange rates.

6.B.vi Inflation Risk

Inflation risk is the potential for financial loss arising from changes in inflation rates. This risk results from insurance contract liabilities that are linked to market measures of inflation such as the Consumer Price Index. The primary sources for this risk exposure are from certain group and retail annuity contracts and group long term disability contracts. In these contracts, the annuity and disability benefit payments may be linked to an indexing formula containing an inflation price index. Benefit payments linked to inflation indices may also include various caps, floors and averaging mechanisms that vary across product designs.

Exposure to inflation risk is managed within our asset-liability management program, primarily by investing in inflation linked assets to match liability exposures.

6.B.vii Additional Cautionary Language and Key Assumptions Related to Sensitivities

Our market risk sensitivities are measures of our estimate change in net income and OCI for changes in market risk variables described above, based on market risk variables and business in force as at the reporting date. These sensitivities are calculated independently for each risk factor, generally assuming that all other risk variables stay constant. The sensitivities do not take into account indirect effects such as potential impacts on goodwill impairment or valuation allowances on deferred tax assets.

We have provided measures of our net income sensitivity to instantaneous changes in equity markets, interest rates, credit spreads, swap spreads, and real estate price levels. The cautionary language which appears in this section is applicable to all net income and OCI sensitivities.

Actual results can differ materially from these estimates for a variety of reasons, including differences in the pattern or distribution of the market shocks, the interaction between these risk factors, model error, or changes in other assumptions such as business mix, effective tax rates, policyholder behaviour, currency exchange rates and other market variables relative to those underlying the calculation of these sensitivities. The extent to which actual results may differ from the indicative ranges will generally increase with larger movements in risk variables. Our sensitivities as at December 31, 2022 have been included for comparative purposes only.

As these market risk sensitivities reflect an instantaneous impact on net income and OCI, they do not include impacts over time such as the effect on fee income in our asset management businesses.

The sensitivities reflect the composition of our assets and liabilities as at June 30, 2023 and December 31, 2022, respectively. Changes in these positions due to new sales or maturities, asset purchases/sales, or other management actions could result in material changes to these reported sensitivities. In particular, these sensitivities reflect the expected impact of hedging activities based on the hedging programs in place as at the June 30 and December 31 calculation dates. The actual impact of hedging activity can differ materially from that assumed in the estimated sensitivities due to ongoing hedge re-balancing activities, changes in the scale or scope of hedging activities, changes in the cost or general availability of hedging instruments, basis risk (i.e., the risk that hedges do not exactly replicate the underlying portfolio experience), model risk, and

108 Sun Life Financial Inc. Second Quarter 2023 CONDENSED NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

other operational risks in the ongoing management of the hedge programs or the potential failure of hedge counterparties to perform in accordance with expectations.

Our hedging programs may themselves expose us to other risks, including basis risk, volatility risk, and increased levels of derivative counterparty credit risk, liquidity risk, model risk and other operational risks. These factors may adversely impact the net effectiveness, costs, and financial viability of maintaining these hedging programs and therefore adversely impact our profitability and financial position. While our hedging programs are intended to mitigate these effects (e.g., hedge counterparty credit risk is managed by maintaining broad diversification, dealing primarily with highly-rated counterparties, and transacting through over-the-counter ("OTC") contracts cleared through central clearing houses, exchange-traded contracts or bilateral OTC contracts negotiated directly between counterparties that include credit support annexes), residual risk, potential reported earnings and capital volatility remain.

The sensitivities are based on methods and assumptions in effect as at June 30, 2023 and December 31, 2022, as applicable. Changes in the regulatory environment, assumptions or methods used to measure assets and liabilities after those dates could result in material changes to the estimated sensitivities. Changes in market risk variables in excess of the changes illustrated may result in other than proportionate impacts.

The sensitivities reflect the CSM as at June 30, 2023 and December 31, 2022. For insurance contracts measured using the VFA, where the change in the effect of the time value of money and financial risk not arising from the underlying items adjusts the CSM, changes in the CSM balance will affect the sensitivity of income to changes in market risk variables.

For the reasons outlined above, our sensitivities should only be viewed as indicative estimates of the underlying sensitivities of each factor under these specialized assumptions, and should not be viewed as predictors of our future income and OCI. Given the nature of these calculations, we cannot provide assurance that actual impacts will be consistent with the estimates provided.

10. Income Taxes

The Company’s effective income tax rate is generally lower than our statutory income tax rate of 27.8% due to various tax benefits, such as lower taxes on income subject to tax in foreign jurisdictions and a range of tax-exempt investment income.

Our effective income tax rate for the three and six months ended June 30, 2023 was 14.6% and 15.5%, respectively, compared to 23.8% and 23.6%, respectively, (restated, see Note 2) for the three and six months ended June 30, 2022. The effective income tax rate for the three and six months ended June 30, 2023 was lower than the effective income tax rate for the three and six months ended June 30, 2022 primarily due to the impact of higher tax exempt income reported in 2023.

11. Capital Management

11.A Capital

Our capital base is structured to exceed minimum regulatory and internal capital targets and maintain strong credit and financial strength ratings, while maintaining a capital efficient structure. We strive to achieve an optimal capital structure by balancing the use of debt and equity financing. Capital is managed both on a consolidated basis under the principles that consider all the risks associated with the business, as well as at the business group level under the principles appropriate to the jurisdiction in which each operates. We manage the capital for all of our international subsidiaries on a local statutory basis in a manner commensurate with their individual risk profiles. Further details on our capital, and how it is managed, are included in Note 21 of our 2022 Annual Consolidated Financial Statements and Note 2.B.iv of our Consolidated Financial Statements.

SLF Inc. is a non-operating insurance company and is subject to the LICAT guideline. As at June 30, 2023, SLF Inc.’s LICAT ratio exceeded the regulatory minimum target as set out by the OSFI.

Sun Life Assurance, SLF Inc.’s principal operating life insurance subsidiary in Canada, is also subject to the LICAT guideline. As at June 30, 2023, Sun Life Assurance's LICAT ratio exceeded OSFI’s minimum regulatory target; as well as OSFI’s supervisory target applicable to operating life insurance companies.

In the U.S., Sun Life Assurance operates through a branch which is subject to U.S. regulatory supervision and it exceeded the levels under which regulatory action would be required as at June 30, 2023. In addition, other subsidiaries of SLF Inc. that must comply with local capital or solvency requirements in the jurisdiction in which they operate maintained capital levels above minimum local requirements as at June 30, 2023.

Our capital base consists mainly of common shareholders’ equity, preferred shareholders’ equity, equity in the participating account, non-controlling interest's equity, CSM, and certain other capital securities that qualify as regulatory capital.

16. Legal and Regulatory Proceedings

We are regularly involved in legal actions, both as a defendant and as a plaintiff. Legal actions naming us as a defendant ordinarily involve our activities as a provider of insurance protection and wealth management products, as an investor and investment advisor, and as an employer. In addition, government and regulatory bodies in Canada, the U.S., the UK, and Asia, including federal, provincial, and state securities and insurance regulators and government authorities, from time to time, make inquiries and require the production of information or conduct examinations or investigations concerning our compliance with insurance, securities, and other laws.

Provisions for legal proceedings related to insurance contracts, such as for disability and life insurance claims and the cost of litigation, are included in Insurance contract liabilities in our Consolidated Statements of Financial Position. Other provisions are established outside of the Insurance contract liabilities if, in the opinion of management, it is both probable that a payment will be required and a reliable estimate can be made of the amount of the obligation. Management reviews the status of all proceedings on an ongoing basis and exercises judgment in resolving them in such manner as management believes to be in our best interest.

Our significant legal proceedings and regulatory matters are disclosed in Note 23.G of our 2022 Annual Consolidated Financial Statements. There have been no significant updates to such legal and regulatory proceedings.

17. Subsequent Events

Effective July 1, 2023 we commenced our 15-year exclusive bancassurance partnership with Dah Sing Bank, Limited as described in Note 3.

On July 4, 2023, SLF Inc. issued $500 principal amount of Series 2023-1 Subordinated Unsecured 5.50% Fixed/Floating Debentures due 2035. SLF Inc. intends to use an amount equal to the net proceeds from the offering to finance or refinance, in whole or in part, eligible assets as defined in our Sustainability Bond Framework.

On July 21, 2023, SLF Inc. announced its intention to redeem all of the outstanding $1,000 principal amount of Series 2016-2 Subordinated Unsecured 3.05% Fixed/Floating Debentures (the "Debentures") in accordance with the redemption terms attached to the Debentures. The redemption will be funded from existing cash and liquid assets. The Debentures are redeemable at SLF Inc.'s option on or after September 19, 2023 at a redemption price per Debenture equal to the principal amount together with accrued and unpaid interest to the date of redemption. SLF Inc. intends to redeem the Debentures on September 19, 2023.

On July 26, 2023, we announced that we entered into an agreement to acquire Dialogue Health Technologies ("Dialogue") in which our current ownership interest will increase from approximately 23% to approximately 97% for estimated cash proceeds of $277. Dialogue is a Canadian based health and wellness virtual care platform and will form a part of our Canada business segment. The transaction is expected to close in 2023, subject to satisfaction of customary closing conditions.

On August 8, 2023, SLF Inc. announced that, subject to the approval of OSFI and the Toronto Stock Exchange (“TSX”), it intends to launch a normal course issuer bid to purchase up to 17 million of its common shares (the “NCIB”). Subject to receipt of regulatory and stock exchange approvals, the NCIB is expected to commence on August 21, 2023 and continue until August 20, 2024, or such earlier date as SLF Inc. may determine. Purchases under the NCIB may be made through the facilities of the TSX, other Canadian stock exchanges and/or alternative Canadian trading platforms, at prevailing market rates. Subject to regulatory approval, purchases under the NCIB may also be made by way of private agreements or share repurchase programs under issuer bid exemption orders issued by securities regulatory authorities. Any purchases made under an exemption order issued by a securities regulatory authority will generally be at a discount to the prevailing market price. The actual number of common shares purchased under the NCIB, and the timing of such purchases (if any), will be determined by SLF Inc. Any common shares purchased by SLF Inc. pursuant to the NCIB will be cancelled or used in connection with certain equity settled incentive arrangements. The NCIB will provide the Company with the flexibility to acquire common shares in order to return capital to shareholders as part of its overall capital management strategy.
