Notes to Condensed Consolidated Financial Statements (Unaudited)

June 30, 2006 and 2005

The accompanying condensed consolidated financial statements of Nationwide Life Insurance Company and subsidiaries (NLIC, or collectively, the Company) have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all information and footnotes required by GAAP for complete financial statements. The financial information included herein reflects all adjustments (all of which are normal and recurring in nature) which are, in the opinion of management, necessary for a fair presentation of financial position and results of operations. Operating results for all periods presented are not necessarily indicative of the results that may be expected for the full year. All significant intercompany balances and transactions have been eliminated. The accompanying condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes for the year ended December 31, 2005 included in the Company’s 2005 Annual Report on Form 10-K.

The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements. Actual results could differ significantly from those estimates.

Certain items in the condensed consolidated financial statements and related notes have been reclassified to conform to the current presentation.

A complete summary of the Company’s significant accounting policies is included in Note 2 to the audited consolidated financial statements included in the Company’s 2005 Annual Report on Form 10-K. During the quarter ended June 30, 2006, there have been no material changes to these policies.

In June 2006, the Financial Accounting Standards Board (FASB) issued FASB Interpretation (FIN) No. 48, Accounting for Uncertainty in Income Taxes, an Interpretation of FASB Statement No. 109, Accounting for Income Taxes (FIN 48). FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements in accordance with FASB Statement No. 109, Accounting for Income Taxes. FIN 48 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. FIN 48 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. FIN 48 is effective for fiscal years beginning after December 15, 2006. The Company plans to adopt FIN 48 effective January 1, 2007. The Company is currently unable to quantify the impact of adopting FIN 48.

In March 2006, the FASB issued Statement of Financial Accounting Standards (SFAS) No. 156, Accounting for Servicing of Financial Assets (SFAS 156). SFAS 156 amends SFAS No. 140, Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities (SFAS 140). SFAS 156 requires that all separately recognized servicing assets and servicing liabilities be initially measured at fair value, if practicable. SFAS 156 permits, but does not require, the subsequent measurement of separately recognized servicing assets and servicing liabilities at fair value. An entity that uses derivative instruments to mitigate the risks inherent in servicing assets and servicing liabilities is required to account for those derivative instruments at fair value. Under SFAS 156, an entity can elect subsequent fair value measurement to account for its separately recognized servicing assets and servicing liabilities. By electing that option, an entity may simplify its accounting because SFAS 156 permits income statement recognition of the potential offsetting changes in fair value of those servicing assets and servicing liabilities and derivative instruments in the same accounting period. SFAS 156 is effective for fiscal years beginning after September 15, 2006, with early adoption permitted. The Company plans to adopt SFAS 156 effective January 1, 2007. SFAS 156 is not expected to have a material impact on the Company’s financial position or results of operations upon adoption.

June 30, 2006 and 2005

In February 2006, the FASB issued SFAS No. 155, Accounting for Certain Hybrid Financial Instruments (SFAS 155). SFAS 155 amends SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities (SFAS 133), and SFAS 140. SFAS 155 also resolves issues addressed in SFAS 133 Implementation Issue No. D1, Application of Statement 133 to Beneficial Interests in Securitized Financial Assets. In summary, SFAS 155: (1) permits an entity to make an irrevocable election to measure any hybrid financial instrument that contains an embedded derivative that otherwise would require bifurcation at fair value in its entirety, with changes in fair value recognized in earnings; (2) clarifies which interest-only strips and principal-only strips are not subject to the requirements of SFAS 133; (3) establishes a requirement to evaluate interests in securitized financial assets to identify interests that are freestanding derivatives or that are hybrid financial instruments that contain an embedded derivative requiring bifurcation; (4) clarifies that concentrations of credit risk in the form of subordination are not embedded derivatives; and (5) amends SFAS 140 to eliminate the prohibition on a qualifying special purpose entity from holding a derivative financial instrument that pertains to a beneficial interest other than another derivative financial instrument. SFAS 155 is effective for all financial instruments acquired or issued after the beginning of an entity’s first fiscal year that begins after September 15, 2006. Earlier adoption is permitted as of the beginning of an entity’s fiscal year, provided the entity has not yet issued financial statements, including financial statements for any interim period for that fiscal year. Provisions of SFAS 155 may be applied to instruments that an entity holds at the date of adoption on an instrument-by-instrument basis. The Company elected to early adopt SFAS 155 as of January 1, 2006. On the date of adoption, there was no impact to the Company’s financial position or results of operations.

In September 2005, the Accounting Standards Executive Committee of the American Institute of Certified Public Accountants issued Statement of Position (SOP) 05-1, Accounting by Insurance Enterprises for Deferred Acquisition Costs in Connection with Modifications or Exchanges of Insurance Contracts (SOP 05-1). SOP 05-1 provides guidance on accounting by insurance enterprises for deferred acquisition costs on internal replacements of insurance and investment contracts other than those specifically described in SFAS No. 97, Accounting and Reporting by Insurance Enterprises for Certain Long-Duration Contracts and for Realized Gains and Losses from the Sale of Investments, issued by the FASB. SOP 05-1 defines an internal replacement as a modification in product benefits, features, rights or coverages that occurs as a result of the exchange of a contract for a new contract, or by amendment, endorsement or rider to a contract, or by the election of a new feature or coverage within a contract. SOP 05-1 is effective for internal replacements occurring in fiscal years beginning after December 15, 2006, with earlier adoption encouraged. Retrospective application of SOP 05-1 to previously issued financial statements is not permitted. Initial application of SOP 05-1 is required as of the beginning of an entity’s fiscal year. The Company will adopt SOP 05-1 effective January 1, 2007. Although the Company is currently unable to quantify the impact of adoption, SOP 05-1 could have a material impact on the Company’s financial position and/or results of operations.

In May 2005, the FASB issued SFAS No. 154, Accounting Changes and Error Corrections (SFAS 154), which replaces Accounting Principles Board Opinion No. 20, Accounting Changes, and SFAS No. 3, Reporting Accounting Changes in Interim Financial Statements. SFAS 154 applies to all voluntary changes in accounting principle as well as to changes required by an accounting pronouncement in the unusual instance that the pronouncement does not include specific transition provisions. SFAS 154 is effective for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005, with earlier adoption permitted. The Company adopted SFAS 154 effective January 1, 2006. SFAS 154 has not had any impact on the Company’s financial position or results of operations since adoption.

The Company’s federal income tax returns for tax years 2000-2002 were under Internal Revenue Service (IRS) examination pursuant to a routine audit. Management establishes tax reserves representing its best estimate of additional amounts the Company may be required to pay if certain positions it has taken are challenged and ultimately denied by the IRS. These reserves are reviewed regularly and are adjusted as events occur that management believes impacts the Company’s liability for additional taxes, such as lapsing of applicable statutes of limitations; conclusion of tax audits or substantial agreement on the deductibility/non-deductibility of uncertain items; additional exposure based on current calculations; identification of new issues; release of administrative guidance; or rendering of a court decision affecting a particular tax issue. A significant component of the tax reserve the Company has maintained was related to the separate account dividends received deduction (DRD).

June 30, 2006 and 2005

In July 2006, the Company reached substantial agreement with the IRS on all open issues for tax years 2000-2002, including issues related to the DRD. Accordingly, the Company revised its estimate of amounts that may be due in connection with certain tax positions, including the DRD, for all open tax years. As a result of the revised estimate, $110.9 million of tax reserves were released into earnings during the quarter ended June 30, 2006.

Total federal income tax (benefit) expense differs from the amount computed by applying the U.S. federal income tax rate to income from continuing operations before federal income tax (benefit) expense as follows for the periods indicated:

The Company and certain affiliated companies participate in a defined benefit pension plan sponsored by Nationwide Mutual Insurance Company (NMIC). The Company funds pension costs accrued for direct employees plus an allocation of pension costs accrued for employees of affiliates whose work benefits the Company.

The following table summarizes the components of net periodic benefit cost for the NMIC pension plan as a whole, including amounts not related to the Company, for the periods indicated:

NMIC and all participating employers, including the Company, expect to contribute $120.0 million to the pension plan during 2006. Through June 30, 2006, $60.0 million had been contributed, all by NMIC. Additional contributions to the plan totaling $60.0 million are anticipated for the remainder of the year, including $16.2 million by the Company. Tax planning strategies influence the timing of plan contributions.

Legal Matters

The Company is a party to litigation and arbitration proceedings in the ordinary course of its business. It is not possible to determine the ultimate outcome of the pending investigations and legal proceedings or to provide reasonable ranges of potential losses. Some matters, including certain of those referred to below, are in very preliminary stages, and the Company does not have sufficient information to make an assessment of the plaintiffs’ claims for liability or damages. In some of the cases seeking to be certified as class actions, the court has not yet decided whether a class will be certified or (in the event of certification) the size of the class and class period. In many of the cases, the plaintiffs are seeking undefined amounts of damages or other relief, including punitive damages and equitable remedies, which are difficult to quantify and cannot be defined based on the information currently available. The Company does not believe, based on information currently known by the Company’s management, that the outcomes of such pending investigations and legal proceedings are likely to have a material adverse effect on the Company’s consolidated financial position. However, given the large and/or indeterminate amounts sought in certain of these matters and inherent unpredictability of litigation, it is possible that an adverse outcome in certain matters could have a material adverse effect on the Company’s consolidated financial results in a particular quarterly or annual period.

In recent years, life insurance companies have been named as defendants in lawsuits, including class action lawsuits relating to life insurance and annuity pricing and sales practices. A number of these lawsuits have resulted in substantial jury awards or settlements against life insurers other than the Company.

June 30, 2006 and 2005

The financial services industry, including mutual fund, variable annuity, life insurance and distribution companies, has also been the subject of increasing scrutiny by regulators, legislators and the media over the past few years. Numerous regulatory agencies, including the United States Securities and Exchange Commission (SEC), the National Association of Securities Dealers and the New York State Attorney General, have commenced industry-wide investigations regarding late trading and market timing in connection with mutual funds and variable insurance contracts, and have commenced enforcement actions against some mutual fund and life insurance companies on those issues. The Company has been contacted by or received subpoenas from the SEC and the New York State Attorney General, who are investigating market timing in certain mutual funds offered in insurance products sponsored by the Company. The Company has cooperated with these investigations. Information requests from the New York State Attorney General and the SEC with respect to investigations into late trading and market timing were last responded to by the Company and its affiliates in December 2003 and June 2005, respectively, and no further information requests have been received with respect to these matters.

In addition, state and federal regulators have commenced investigations or other proceedings relating to compensation and bidding arrangements and possible anti-competitive activities between insurance producers and brokers and issuers of insurance products, and unsuitable sales and replacements by producers on behalf of the issuer. Also under investigation are compensation and revenue sharing arrangements between the issuers of variable insurance contracts and mutual funds or their affiliates, the use of side agreements and finite reinsurance agreements, and funding agreements issued to back medium-term note (MTN) programs. Related investigations and proceedings may be commenced in the future. The Company and/or its affiliates have been contacted by or received subpoenas from state and federal regulatory agencies, state securities law regulators and state attorneys general for information relating to these investigations into compensation, revenue sharing and bidding arrangements, anti-competitive activities, unsuitable sales or replacement practices, the use of side agreements and finite reinsurance agreements, and funding agreements backing the MTN program of NLIC. The Company is cooperating with regulators in connection with these inquiries and will cooperate with NMIC in responding to these inquiries to the extent that any inquiries encompass NMIC’s operations.

These proceedings are expected to continue in the future and could result in legal precedents and new industry-wide legislation, rules and regulations that could significantly affect the financial services industry, including life insurance and annuity companies. These proceedings also could affect the outcome of one or more of the Company’s litigation matters. There can be no assurance that any such litigation or regulatory actions will not have a material adverse effect on the Company in the future.

On February 11, 2005, NLIC was named in a class action lawsuit filed in Common Pleas Court, Franklin County, Ohio entitled Michael Carr v. Nationwide Life Insurance Company. The complaint seeks recovery for breach of contract, fraud by omission, violation of the Ohio Deceptive Trade Practices Act and unjust enrichment. The complaint also seeks unspecified compensatory damages, disgorgement of all amounts in excess of the guaranteed maximum annual premium and attorneys’ fees. On February 2, 2006, the Court granted the plaintiff’s motion for class certification on the breach of contract and unjust enrichment claims. The Court certified a class consisting of all residents of the United States and the Virgin Islands who, during the Class Period, paid premiums on a modal basis to NLIC for term life insurance policies issued by NLIC during the Class Period that provide for guaranteed maximum premiums, excluding certain specified products. Excluded from the class are NLIC; any parent, subsidiary or affiliate of NLIC; all employees, officers and directors of NLIC; and any justice, judge or magistrate judge of the State of Ohio who may hear the case. The Class Period is from February 10, 1990 through February 2, 2006, the date the class was certified. NLIC continues to defend this lawsuit vigorously.

June 30, 2006 and 2005

On April 13, 2004, NLIC was named in a class action lawsuit filed in Circuit Court, Third Judicial Circuit, Madison County, Illinois, entitled Woodbury v. Nationwide Life Insurance Company. NLIC removed this case to the United States District Court for the Southern District of Illinois on June 1, 2004. On December 27, 2004, the case was transferred to the United States District Court for the District of Maryland and included in the multi-district proceeding entitled In Re Mutual Funds Investment Litigation. In response, on May 13, 2005, the plaintiff filed a First Amended Complaint purporting to represent, with certain exceptions, a class of all persons who held (through their ownership of an NLIC annuity or insurance product) units of any NLIC sub-account invested in mutual funds that included foreign securities in their portfolios and that experienced market timing or stale price trading activity. The First Amended Complaint purports to disclaim, with respect to market timing or stale price trading in NLIC’s annuities sub-accounts, any allegation based on NLIC’s untrue statement, failure to disclose any material fact, or usage of any manipulative or deceptive device or contrivance in connection with any class member’s purchases or sales of NLIC annuities or units in annuities sub-accounts. The plaintiff claims, in the alternative, that if NLIC is found with respect to market timing or stale price trading in its annuities sub-accounts, to have made any untrue statement, to have failed to disclose any material fact or to have used or employed any manipulative or deceptive device or contrivance, then the plaintiff purports to represent a class, with certain exceptions, of all persons who, prior to NLIC’s untrue statement, omission of material fact, use or employment of any manipulative or deceptive device or contrivance, held (through their ownership of an NLIC annuity or insurance product) units of any NLIC sub-account invested in mutual funds that included foreign securities in their portfolios and that experienced market timing activity. The First Amended Complaint alleges common law negligence and seeks to recover damages not to exceed $75,000 per plaintiff or class member, including all compensatory damages and costs. On June 1, 2006, the District Court granted NLIC’s motion to dismiss the plaintiff’s complaint. On June 30, 2006, the plaintiff filed a notice of appeal. NLIC continues to defend this lawsuit vigorously.

On January 21, 2004, NLIC, Nationwide Life Insurance Company of America (NLICA), Nationwide Life and Annuity Insurance Company (NLAIC), NFS and Nationwide Financial Corporation (collectively referred to as the Companies) were named in a lawsuit filed in the United States District Court for the Northern District of Mississippi entitled United Investors Life Insurance Company v. Nationwide Life Insurance Company and/or Nationwide Life Insurance Company of America and/or Nationwide Life and Annuity Insurance Company and/or Nationwide Life and Annuity Company of America and/or Nationwide Financial Services, Inc. and/or Nationwide Financial Corporation, and John Does A-Z. In its complaint, the plaintiff alleges that the Companies and/or their affiliated life insurance companies caused the replacement of variable insurance policies and other financial products issued by United Investors with policies issued by the Companies. The plaintiff raises claims for (1) violations of the Federal Lanham Act, and common law unfair competition and defamation; (2) tortious interference with the plaintiff’s contractual relationship with Waddell & Reed, Inc. and/or its affiliates, Waddell & Reed Financial, Inc., Waddell & Reed Financial Services, Inc. and W&R Insurance Agency, Inc., or with the plaintiff’s contractual relationships with its variable policyholders; (3) civil conspiracy; and (4) breach of fiduciary duty. The complaint seeks compensatory damages, punitive damages, pre- and post-judgment interest, a full accounting, a constructive trust and costs and disbursements, including attorneys’ fees. On December 30, 2005, the Companies filed a motion for summary judgment. On June 15, 2006, the District Court granted the Companies’ motion for summary judgment on all grounds and dismissed the plaintiff’s entire case with prejudice. On June 26, 2006, the plaintiff filed a notice of its intent to appeal the District Court’s decision. The Companies continue to defend this lawsuit vigorously.

On October 31, 2003, NLIC and NLAIC were named in a lawsuit seeking class action status filed in the United States District Court for the District of Arizona. The suit, entitled Robert Helman et al v. Nationwide Life Insurance Company et al, challenges the sale of deferred annuity products for use as investments in tax-deferred contributory retirement plans. On April 8, 2004, the plaintiff filed an amended class action complaint on behalf of all persons who purchased an individual variable deferred annuity contract or a certificate to a group variable annuity contract issued by NLIC or NLAIC, which were allegedly used to fund certain tax-deferred retirement plans. The amended class action complaint seeks unspecified compensatory damages. On July 27, 2004, the District Court granted the motion to dismiss filed by NLIC and NLAIC. On June 7, 2006, the Ninth Circuit Court of Appeals affirmed the District Court’s granting of the motion to dismiss. To the extent this decision is appealed to the U.S. Supreme Court, NLIC and NLAIC intend to continue to defend this lawsuit vigorously.

On August 15, 2001, NFS and NLIC were named in a lawsuit filed in the United States District Court for the District of Connecticut entitled Lou Haddock, as trustee of the Flyte Tool & Die, Incorporated Deferred Compensation Plan, et al v. Nationwide Financial Services, Inc. and Nationwide Life Insurance Company. Currently, the plaintiffs’ fifth amended complaint, filed March 21, 2006, purports to represent a class of qualified retirement plans under the Employee Retirement Income Security Act of 1974, as amended (ERISA), that purchased variable annuities from NLIC. The plaintiffs allege that they invested ERISA plan assets in their variable annuity contracts and that NLIC and NFS breached ERISA fiduciary duties by allegedly accepting service payments from certain mutual funds. The complaint seeks disgorgement of some or all of the payments allegedly received by NLIC and NFS, other unspecified relief for restitution, declaratory and injunctive relief, and attorneys’ fees. To date, the District Court has rejected the plaintiffs’ request for certification of the alleged class. On April 20, 2006, NLIC and NFS filed a motion to dismiss the plaintiffs’ fifth amended complaint. NLIC and NFS continue to defend this lawsuit vigorously.

Tax Matters

The Company’s federal income tax returns are routinely audited by the IRS. Management has established tax reserves representing its best estimate of additional amounts it may be required to pay if certain tax positions it has taken are challenged and ultimately denied by the IRS. These reserves are reviewed regularly and are adjusted as events occur that management believes impact its liability for additional taxes, such as lapsing of applicable statutes of limitations, conclusion of tax audits or substantial agreement on the deductibility/non-deductibility of uncertain items, additional exposure based on current calculations, identification of new issues, release of administrative guidance or rendering of a court decision affecting a particular tax issue. Management believes its tax reserves reasonably provide for potential assessments that may result from IRS examinations and other tax-related matters for all open tax years.

Since 2001, the Company has sold $626.1 million of credit enhanced equity interests in Low-Income-Housing Tax Credit Funds (Tax Credit Funds) to unrelated third parties. The Company has guaranteed cumulative after-tax yields to the third party investors ranging from 3.75% to 5.25% over periods ending between 2002 and 2022. As of June 30, 2006, the Company held guarantee reserves totaling $6.3 million on these transactions. These guarantees are in effect for periods of approximately 15 years each. The Tax Credit Funds provide a stream of tax benefits to the investors that will generate a yield and return of capital. If the tax benefits are not sufficient to provide these cumulative after-tax yields, then the Company must fund any shortfall, which is mitigated by stabilization collateral set aside by the Company at the inception of the transactions. The maximum amount of undiscounted future payments that the Company could be required to pay the investors under the terms of the guarantees is $1.44 billion. The Company does not anticipate making any payments related to these guarantees.

To the extent there are cash deficits in any specific property owned by the Tax Credit Funds, property reserves, property operating guarantees and reserves held by the Tax Credit Funds are exhausted before the Company is required to perform under its guarantees. To the extent the Company is ever required to perform under its guarantees, it may recover any such funding out of the cash flow distributed from the sale of the underlying properties of the Tax Credit Funds. This cash flow distribution would be paid to the Company prior to any cash flow distributions to unrelated third party investors.

As of June 30, 2006 and December 31, 2005, the Company had relationships with 19 variable interest entities (VIEs), each of which the Company was the primary beneficiary. Each of these VIEs is a conduit that assists the Company in structured product transactions. One of the VIEs is used in the securitization of mortgage loans, while the others are involved in the sale of Tax Credit Funds to third party investors for which the Company provides guaranteed returns (see Note 8). The results of operations and financial position of these VIEs are included along with corresponding minority interest liabilities in the accompanying condensed consolidated financial statements.

The net assets of these VIEs totaled $446.9 million and $440.6 million as of June 30, 2006 and December 31, 2005, respectively. The following table summarizes the components of net assets as of the dates indicated:

The Company’s total loss exposure from VIEs of which the Company is the primary beneficiary was immaterial as of June 30, 2006 and December 31, 2005 (except for the impact of guarantees disclosed in Note 8). For the mortgage loan VIE, to which the short-term debt relates, the creditors have no recourse against the Company in the event of default by the VIE.

In addition to the VIEs described above, the Company holds variable interests, in the form of limited partnerships or similar investments, in a number of Tax Credit Funds of which the Company is not the primary beneficiary. These investments have been held by the Company for periods of 1 to 10 years and allow the Company to experience certain tax credits and other tax benefits from affordable housing projects. The Company also has certain investments in other securitization transactions that qualify as VIEs, but of which the Company is not the primary beneficiary. The total exposure to loss on these VIEs was $65.3 million and $53.9 million as of June 30, 2006 and December 31, 2005, respectively.

June 30, 2006 and 2005

Management views the Company’s business primarily based on its underlying products and uses this basis to define its four reportable segments: Individual Investments, Retirement Plans, Individual Protection, and Corporate and Other.

The primary segment profitability measure that management uses is pre-tax operating earnings, which is calculated by adjusting income from continuing operations before federal income taxes to exclude: (1) net realized gains and losses on investments, hedging instruments and hedged items, except for periodic net coupon settlements on non-qualifying derivatives; (2) net realized gains and losses related to securitizations; and (3) the adjustment to amortization of deferred policy acquisition costs (DAC) related to net realized gains and losses.

Individual Investments

The Individual Investments segment consists of individual The BEST of AMERICA® and private label deferred variable annuity products, deferred fixed annuity products, income products and advisory services. Individual deferred annuity contracts provide the customer with tax-deferred accumulation of savings and flexible payout options including lump sum, systematic withdrawal or a stream of payments for life. In addition, individual variable annuity contracts provide the customer with access to a wide range of investment options and asset protection in the event of an untimely death, while individual fixed annuity contracts generate a return for the customer at a specified interest rate fixed for prescribed periods.

Retirement Plans

The Retirement Plans segment is comprised of the Company’s private and public sector retirement plans business. The private sector includes Internal Revenue Code (IRC) Section 401 and Section 403 business, and the public sector includes IRC Section 457 and Section 401(a) business, both in the form of fixed and variable group annuities.
