Overview

We are a biopharmaceutical company developing next-generation programmed T cell therapies for the treatment of cancer. Using our broad suite of proprietary and modular T cell programming technologies, we are engineering precisely targeted, controlled and highly active T cell therapies that are designed to better recognize cancer cells, break down their defense mechanisms and attack and kill these cells. We believe our programmed T cell therapies have the potential to be best-in-class and offer cancer patients substantial benefits over the existing standard of care, including the potential for cure in some patients.

Since our inception in July 2014, we have devoted substantially all of our resources to conducting preclinical studies and clinical trials, organizing and staffing our company, business planning, raising capital and establishing our intellectual property portfolio. We do not have any products approved for sale and have not generated any revenue from product sales. We have funded our operations to date primarily with proceeds from government grants and sales of our equity securities, including the net proceeds from our initial public offering of American Depository Shares, or ADSs, in June 2018 and our follow-on offerings in April 2019 and January 2020. From inception through March 31, 2020, we have received aggregate net proceeds of $516.1 million from sales of our equity securities. We do not expect to generate significant revenue unless and until we obtain marketing approval for and commercialize one of our product candidates.

Since our inception, we have incurred significant operating losses. For the three months ended March 31, 2020, we incurred a net loss of $29.9 million and had an accumulated deficit of $267.0 million.

We expect to continue to incur significant expenses for the foreseeable future as we advance our product candidates through preclinical and clinical development, seek regulatory approval and pursue commercialization of any approved product candidates. In addition, if we obtain marketing approval for any of our product candidates, we expect to incur significant commercialization expenses related to product manufacturing, marketing, sales and distribution. In addition, we may incur expenses in connection with the in-license or acquisition of additional product candidates. Furthermore, we have incurred and expect to continue to incur, additional costs associated with operating as a public company, including significant legal, accounting, investor relations and other expenses that we did not incur as a private company.


1


As a result, we will need substantial additional funding to support our continuing operations and pursue our growth strategy. Until such time as we can generate significant revenue from product sales, if ever, we expect to finance our operations through the sale of equity, debt financings or other capital sources, including potential collaborations with other companies or other strategic transactions. We may be unable to raise additional funds or enter into such other agreements or arrangements when needed on favorable terms, or at all. If we fail to raise capital or enter into such agreements as, and when, needed, we may have to significantly delay, scale back or discontinue the development and commercialization of one or more of our drug candidates or delay our pursuit of potential in-licenses or acquisitions.

As of March 31, 2020, we had cash on hand of $243.3 million. Based on our current clinical development plans, we believe our existing cash and cash equivalents will be able to fund our current and planned operating expenses and capital expenditure requirements through at least the next 12 months. We have based this estimate on assumptions that may prove to be wrong, and we could deplete our available capital resources sooner than we expect.

COVID-19 Business Update

With the global spread of the ongoing COVID-19 pandemic in the first quarter of 2020, we established a cross-functional task force and have implemented business continuity plans designed to address and mitigate the impact of the COVID-19 pandemic on our employees and our business.  While we are not experiencing financial impacts at this time, given the global economic slowdown, the overall disruption of global healthcare systems and the other risks and uncertainties associated with the pandemic, our business, financial condition, results of operations and growth prospects could be materially adversely affected.  We continue to closely monitor the COVID-19 situation as we evolve our business continuity plans and response strategy.  In March 2020, our global workforce transitioned to working remotely.  We are currently preparing plans to reopen our offices to allow employees to return to their offices, which will be based on a phased approach that is principles-based and local in design, with a focus on continuity of patient treatment, employee safety and optimal work environment. As of and for the three months ended March 31, 2020, we are not aware of any specific event or circumstance that is having an impact on our operations which would require us to update our estimates, judgments or revise the carrying value of our assets or liabilities.

Components of Our Results of Operations
Grant Income
Grant income consists of proceeds from government research grants used to perform specific research and development activities. We recognize grant income over the period in which we recognize the related costs covered under the terms and conditions of the grant. We have received grants from the U.K. government, which are repayable under certain circumstances, including breach or noncompliance with the terms of the grant. For grants with refund provisions, we review the grant to determine the likelihood of repayment. If the likelihood of repayment of the grant is determined to be remote, then the grant is recognized as grant income.
Operating Expenses
Research and Development Expenses
Research and development expenses consist of costs incurred in connection with the research and development of our product candidates, which are partially offset by research and development expenditure tax credits provided by Her Majesty’s Revenue & Customs, or HMRC. We expense research and development costs as incurred. These expenses include:
•
expenses incurred under agreements with contract research organizations, or CROs, as well as investigative sites and consultants that conduct our clinical trials, preclinical studies and other scientific development services;
•
manufacturing scale-up expenses and the cost of acquiring and manufacturing preclinical and clinical trial materials;
•
employee-related expenses, including salaries, related benefits, travel and share-based compensation expense for employees engaged in research and development functions;
•
expenses incurred for outsourced professional scientific development services;
•
costs for laboratory materials and supplies used to support our research activities;
•
allocated facilities costs, depreciation and other expenses, which include rent and utilities; and

2


•
upfront, milestone and management fees for maintaining licenses under our third-party licensing agreements.
We recognize external development costs based on an evaluation of the progress to completion of specific tasks using information provided to us by our service providers.
Our direct research and development expenses are tracked on a program-by-program basis for our product candidates and consist primarily of external costs, such as fees paid to outside consultants and CROs in connection with our preclinical development, manufacturing and clinical development activities. Our direct research and development expenses by program also include fees incurred under license agreements. We do not allocate employee costs or facility expenses, including depreciation or other indirect costs, to specific programs because these costs are deployed across multiple programs and, as such, are not separately classified. We use internal resources primarily to oversee research and development as well as for managing our preclinical development, process development, manufacturing and clinical development activities.
The following tables summarize our research and development expenses incurred by program:

Research and development activities are central to our business model. Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. As a result, we expect that our research and development expenses will increase substantially over the next few years as we increase personnel costs, initiate and conduct additional clinical trials and prepare regulatory filings related to our product candidates. We also expect to incur additional expenses related to milestone, royalty payments and maintenance fees payable to third parties with whom we have entered into license agreements to acquire the rights related to our product candidates.
The successful development and commercialization of our product candidates is highly uncertain. At this time, we cannot reasonably estimate or know the nature, timing and costs of the efforts that will be necessary to complete the clinical development of any of our product candidates or when, if ever, material net cash inflows may commence from sales of any of our product candidates. This uncertainty is due to the numerous risks and uncertainties associated with development and commercialization activities, including the uncertainty of:
•
the scope, progress, outcome and costs of our clinical trials and other research and development activities, including establishing an appropriate safety profile with IND-directed studies;
•
successful patient enrollment in, and the initiation and completion of, clinical trials;
•
the timing, receipt and terms of any marketing approvals from applicable regulatory authorities;
•
establishing commercial manufacturing capabilities or making arrangements with third-party manufacturers;
•
development and timely delivery of commercial-grade drug formulations that can be used in our clinical trials and for commercial manufacturing;
•
obtaining, maintaining, defending and enforcing patent claims and other intellectual property rights;

3


•
significant and changing government regulation;
•
launching commercial sales of our product candidates, if and when approved, whether alone or in collaboration with others;
•
maintaining a continued acceptable safety profile of the product candidates following approval; and
•
significant competition and rapidly changing technologies within the biopharmaceutical industry.
We may never succeed in achieving regulatory approval for any of our product candidates. We may obtain unexpected results from our clinical trials. We may elect to discontinue, delay or modify clinical trials of some product candidates or focus on others. Any changes in the outcome of any of these variables with respect to the development of our product candidates in clinical development could mean a significant change in the costs and timing associated with the development of these product candidates. For example, if the EMA, the FDA, or another regulatory authority were to delay our planned start of clinical trials or require us to conduct clinical trials or other testing beyond those that we currently expect or if we experience significant delays in enrollment in any of our planned clinical trials, we could be required to expend significant additional financial resources and time on the completion of clinical development of that product candidate. Commercialization of our product candidates will take several years and millions of dollars in development costs.
General and Administrative Expenses
General and administrative expenses consist primarily of salaries, related benefits, travel and share-based compensation expense for personnel in executive, finance, legal and administrative functions. General and administrative expenses also include allocated facility-related costs, patent filing and prosecution costs and professional fees for marketing, insurance, legal, consulting, accounting and audit services.
We anticipate that our general and administrative expenses will increase in the future as we increase our headcount to support the planned development of our product candidates. We anticipate continued increased costs associated with being a U.S. public company, including accounting, audit, legal, regulatory and compliance expenses associated with maintaining compliance with Nasdaq listing rules and SEC requirements, director and officer insurance premiums, and higher investor and public relations costs.
Additionally, if we believe a regulatory approval of one of our product candidates appears likely, we would anticipate an increase in payroll and third party expense as a result of our preparation for commercial operations, especially as it relates to the sales and marketing of our product candidate.
Other Income (Expense)
Other income consists primarily of interest income earned on our cash balances held at a commercial banks and foreign currency transaction gains (losses).
Income Tax Benefit
We are subject to corporate taxation in the United Kingdom and in the United States. Due to the nature of our business, we have generated losses since inception. Our income tax credit recognized represents the sum of the research and development tax credits recoverable in the United Kingdom and income tax payable in the United States.
As a company that carries out extensive research and development activities, we benefit from the U.K. research and development tax credit regime under the scheme for small or medium-sized enterprises, or SMEs, and also claim a Research and Development Expenditure Credit, or RDEC, to the extent that our projects are grant funded. Under the SME regime, we are able to surrender some of our trading losses that arise from our qualifying research and development activities for a cash rebate of up to 33.35% of such qualifying research and development expenditure. The net tax benefit of the RDEC is expected to be 9.7% in the year ending December 31, 2020. We meet the conditions of the SME regime, but also can make claims under the RDEC regime to the extent that our projects are grant funded. Qualifying expenditures largely comprise employment costs for research staff, consumables, outsourced CRO costs and utilities costs incurred as part of research projects. Certain subcontracted qualifying research and development expenditures are eligible for a cash rebate of up to 21.67%. A large portion of costs relating to our research and development, clinical trials and manufacturing activities are eligible for inclusion within these tax credit cash rebate claims.
We may not be able to continue to claim research and development tax credits under the SME regime in the future because we may no longer qualify as a small or medium-sized company. However, we should continue to be able to make claims under the RDEC regime.

4


Un-surrendered U.K. losses may be carried forward indefinitely to be offset against future taxable profits, subject to numerous utilization criteria and restrictions. The amount that can be offset each year is limited to £5.0 million plus an incremental 50% of U.K. taxable profits. After accounting for tax credits receivable, there were accumulated tax losses for carry forward in the United Kingdom of $139.6 million as of March 31, 2020. The Company carries a $0.4 million deferred tax asset balance related to the U.S. entity. The Company has recorded a valuation allowance against the net deferred tax asset where the recoverability due to future taxable profits is unknown.
In the event we generate revenues in the future, we may benefit from the new U.K. “patent box” regime that allows profits attributable to revenues from patents or patented products to be taxed at an effective rate of 10%.
Value Added Tax, or VAT, is broadly charged on all taxable supplies of goods and services by VAT-registered businesses. Under current rates, an amount of 20% of the value, as determined for VAT purposes, of the goods or services supplied is added to all sales invoices and is payable to HMRC. Similarly, VAT paid on purchase invoices is generally reclaimable from HMRC.

Grant Income
Grant income decreased to $0.3 million for the three months ended March 31, 2020 compared to $2.0 million for the three months ended March 31, 2019. The decrease in grant income of $1.6 million was related to a decrease in reimbursable expenditures related to a one-time grant completed in the three months ended March 31, 2019 that did not exist in the three months ended March 31, 2020 submitted to the U.K. government as part of the reimbursement terms of government research grants used to perform specific research and development activities.
Research and Development Expenses
Research and development expenses increased to $31.3 million for the three months ended March 31, 2020 from $22.6 million for the three months ended March 31, 2019. Cash costs, which exclude depreciation and amortization as well as share-based compensation, increased to $25.6 million from $17.5 million. The increase in research and development cash costs of $8.1 million consisted primarily of an increase of compensation-related costs of $2.2 million due to an increase in employee headcount to support the advancement of our product candidates in clinical development, an increase of $3.7 million in project expenses due to the advancement our clinical portfolio which includes research and process development and manufacturing activities necessary to prepare, activate, and monitor clinical trial programs, an increase of $1.8 million in licenses, legal fees and consulting services related to an option to negotiate a future license as well as IT infrastructure and support, and other additional costs in the amount of $0.4 million.

5


Non-cash costs increased to $5.7 million for the three months ended March 31, 2020 from $5.1 million for the three months ended March 31, 2019. The increase is primarily related to share-based compensation expense included in research and development expenses, which increased by $0.4 million as a result of an increase in the number of stock options and restricted stock units granted in December 2019, and, to a lesser degree, an increase of $0.2 million in depreciation related to the purchase of equipment to support our clinical trials and research activities and leasehold improvements.
General and Administrative Expenses
General and administrative expenses decreased to $7.6 million for the three months ended March 31, 2020 from $9.6 million for the three months ended March 31, 2019. Cash costs, which exclude depreciation expense as well as share-based expense compensation decreased to $5.9 million from $6.3 million. Compensation related expenses decreased by $0.3 million and IT, telecommunication, facility and general office expense costs decreased by $0.3 million, and a decrease of $0.3 million in commercial costs which were offset by an increase in public company costs of $0.5 million primarily related to insurance.
Non-cash costs decreased to $1.7 million for the three months ended March 31, 2020 from $3.3 million for the three months ended March 31, 2019. The decrease is attributed to share-based compensation expense included in general and administrative expenses, which decreased by $1.6 million as a result of the lower fair value of stock options recognized during the period.
Interest Income
Interest income remained mostly unchanged at $0.5 million for the three months ended March 31, 2020 compared to $0.5 million for the three months ended March 31, 2019.

Other Income (Expense)

Other income increased to $4.5 million for the three months ended March 31, 2020 from other expense of $1.0 million for the three months ended March 31, 2019 primarily due an increase of the U.S. dollar exchange rate relative to the pound sterling during the three months ending March 31, 2020 as compared to the three months ended March 31, 2019.
Income Tax Benefit
Income tax benefit increased to $3.7 million for the three months ended March 31, 2020 from $3.4 million for the three months ended March 31, 2019 due to increased R&D expenses and U.S tax treatment of the Foreign Derived Intangible Income (FDII), offset by foreign exchange gain. Research and development credits are obtained at a maximum rate of 33.35% of our qualifying research and development expenses, and the increase in the net credit was primarily attributable to an increase in our eligible research and development expenses.
Liquidity and Capital Resources.
Since our inception, we have not generated any product revenue and have incurred operating losses and negative cash flows from our operations. We expect to incur significant expenses and operating losses for the foreseeable future as we advance our product candidates through preclinical and clinical development, seek regulatory approval and pursue commercialization of any approved product candidates. We expect that our research and development and general and administrative costs will increase in connection with our planned research activities. As a result, we will need additional capital to fund our operations until such time as we can generate significant revenue from product sales.
We do not currently have any approved products and have never generated any revenue from product sales or otherwise. We have funded our operations to date primarily with proceeds from government grants and sales of our equity securities. Through March 31, 2020, we have received aggregate net cash proceeds of $516.1 million from sales of our equity securities. As of March 31, 2020, we had cash of $243.3 million.
We currently have no ongoing material financing commitments, such as lines of credit or guarantees, which are expected to affect our liquidity over the next five years, other than our lease obligations and supplier purchase commitments described below.

Net Cash Used in Operating Activities
During the three months ended March 31, 2020, operating activities used $24.0 million of cash, resulting from our net loss of $29.9 million, and net cash used resulting from changes in our operating assets and liabilities of $1.5 million, partially offset by non-cash charges of $7.3 million. Net cash used resulting from changes in our operating assets and liabilities for the three months ended March 31, 2020 consisted primarily of a $1.4 million increase in prepaid expenses and other assets, current and non-current, decrease in accrued expenses of $0.4 million, offset by $0.5 million decrease in right of use assets from amortization and lease liabilities, net.
During the three months ended March 31, 2019, operating activities used $26.5 million of cash, resulting from our net loss of $27.2 million, and net cash used resulting from changes in our operating assets and liabilities of $8.4 million, partially offset by non-cash charges of $9.0 million. Net cash used resulting from changes in our operating assets and liabilities for the three months ended March 31, 2019 consisted primarily of a $6.8 million increase in prepaid expenses and other assets, a $0.7 million increase in long-term deposits, a $0.9 million decrease in accounts payable and accrued expenses.
Net Cash Used in Investing Activities
During the three months ended March 31, 2020 and 2019, we used $2.6 million and $7.3 million, respectively, of cash in investing activities, which consisted of purchases of property and equipment.
Net Cash Provided by Financing Activities
During the three months ended March 31, 2020, net cash provided by financing activities was $74.3 million, consisting of $74.0 million net cash proceeds from our January 2020 follow-on offering and $0.3 million in unpaid issuance costs. There was minimal cash provided by employee stock option exercises.
During the three months ended March 31, 2019 there was minimal cash provided by employee stock option exercises.
Funding Requirements
We expect our expenses to increase substantially in connection with our ongoing activities, particularly as we advance the preclinical activities and clinical trials of our product candidates. Our expenses will increase as we:
•
seek regulatory approvals for any product candidates that successfully complete preclinical and clinical trials;
•
establish a sales, marketing and distribution infrastructure in anticipation of commercializing of any product candidates for which we may obtain marketing approval and intend to commercialize on our own or jointly;
•
hire additional clinical, medical and development personnel;
•
expand our infrastructure and facilities to accommodate our growing employee base; and
•
maintain, expand and protect our intellectual property portfolio.

7


Our primary uses of capital are, and we expect will continue to be, compensation and related expenses, clinical costs, external research and development services, laboratory and related supplies, legal and other regulatory expenses, and administrative and overhead costs. Our future funding requirements will be heavily determined by the resources needed to support development of our product candidates.
Based on our current clinical development plans, we believe our existing cash of $243.3 million at March 31, 2020 will be sufficient to fund our current and planned operating expenses and capital expenditure requirements for at least the next 12 months. We have based these estimates on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we expect. If we receive regulatory approval for our other product candidates, we expect to incur significant commercialization expenses related to product manufacturing, sales, marketing and distribution, depending on where we choose to commercialize. We may also require additional capital to pursue in-licenses or acquisitions of other product candidates.
Because of the numerous risks and uncertainties associated with research, development and commercialization of pharmaceutical product candidates, we are unable to estimate the exact amount of our working capital requirements. Our future funding requirements will depend on and could increase significantly as a result of many factors, including:
•
the scope, progress, outcome and costs of our clinical trials and other research and development activities;
•
the costs, timing, receipt and terms of any marketing approvals from applicable regulatory authorities;
•
the costs of future activities, including product sales, medical affairs, marketing, manufacturing and distribution, for any of our product candidates for which we receive marketing approval;
•
the revenue, if any, received from commercial sale of our products, should any of our product candidates receive marketing approval;
•
the costs and timing of hiring new employees to support our continued growth;
•
the costs of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending intellectual property-related claims; and
•
the extent to which we in-license or acquire additional product candidates or technologies.
Until such time, if ever, that we can generate product revenue sufficient to achieve profitability, we expect to finance our cash needs through equity offerings. To the extent that we raise additional capital through the sale of equity, your ownership interest will be diluted. If we raise additional funds through other third-party funding, collaborations agreements, strategic alliances, licensing arrangements or marketing and distribution arrangements, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity financings when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market products or product candidates that we would otherwise prefer to develop and market ourselves.
Critical Accounting Policies and Significant Judgments and Estimates
Our condensed consolidated financial statements are prepared in accordance with U.S. GAAP. The preparation of our condensed consolidated financial statements and related disclosures requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, costs and expenses, and the disclosure of contingent assets and liabilities in our condensed consolidated financial statements. We base our estimates on historical experience, known trends and events and various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates under different assumptions or conditions.
While our significant accounting policies are described in more detail in Note 2 to our condensed consolidated financial statements appearing in Exhibit 99.1 of this Report on Form 6-K, we believe that the following accounting policies are those most critical to the judgments and estimates used in the preparation of our condensed consolidated financial statements.

Share-Based Compensation
We issue ordinary shares as well as options and other securities exercisable for or convertible into ordinary shares or ADSs as incentives to our employees and directors. To the extent such incentives are in the form of share options, the options are granted pursuant to the terms of our 2017 Share Option Plan, or the 2017 Plan, or pursuant to the terms of our 2018 Equity Incentive Plan, or the 2018 Plan. Options granted under the 2017 Plan and 2018 Plan, as well as shares granted as employee incentives, typically vest over a four-year service period with 25% of the award vesting on the first anniversary of the commencement date and the balance vesting monthly over the remaining three years, unless the awards contain specific performance vesting provisions. For equity awards issued that have both a performance vesting condition and a services condition, or performance awards, once the performance criteria is achieved, the performance awards are then subject to a four-year service vesting with 25% of the performance award vesting on the first anniversary of the performance condition being achieved, with the balance vesting monthly over the remaining three years. For certain members of senior management and directors, the board has approved an alternative vesting schedule for the equity awards. The options granted under the 2017 Plan and 2018 Plan generally expire ten years from the date of grant. We expect our share-based compensation expense for awards granted to employees, directors and other service providers to increase in future periods due to planned increases in our headcount.
We recognize compensation expense for equity awards based on the grant date fair value of the award. For equity awards that vest based on a service condition, the share-based compensation expense is recognized on a straight-line basis over the requisite service period. For equity awards that contain both performance and service conditions, we recognize share-based compensation expense ratably over the requisite service period when the achievement of a performance-based milestone is probable based on the relative satisfaction of the performance condition as of the reporting date. We use the fair value of our ordinary shares to determine the fair value of restricted share awards.
Share-based compensation is recognized as an expense in the condensed consolidated financial statements based on the grant date fair value over the requisite service period. For awards granted to our employees and directors that vest based on service conditions, we use the accelerated method to allocate compensation expense to reporting periods. We do not adjust share-based compensation for estimated forfeitures and account for forfeitures when they occur.
We use the Black-Scholes option pricing model to estimate the fair value of share options. This option-pricing model requires the input of various subjective assumptions, including the option’s expected life and the price volatility of the security.
The fair value of each share option grant is estimated on the date of grant using the Black-Scholes option pricing model and applying assumptions used in connection with option grants made during the periods covered by these condensed consolidated financial statements. Assumptions used in the option pricing model include the following:
Expected volatility.  We lack company-specific historical and implied volatility information for our ADSs. Therefore, we estimate the expected share volatility based on the historical volatility of publicly traded peer companies and expect to continue to do so until such time as we have adequate historical data regarding the volatility of our own traded security price.
Expected term.  The expected term of options granted represents the weighted average period of time that options granted are expected to be outstanding giving consideration to vesting schedules and our historical exercise patterns. The expected term of our share options has been determined utilizing the “simplified” method for awards that qualify as “plain-vanilla” options.

Risk-free interest rate.  The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods that are approximately equal to the expected term of the award.
Expected dividend.  Expected dividend yield of zero is based on the fact that we have never paid cash dividends on ordinary shares and do not expect to pay any cash dividends in the foreseeable future.
Fair value of ordinary shares.  Options granted after our IPO are issued at the fair market value of our ADSs at the date the grant is approved by the Board.

Income Taxes

We account for income taxes under the asset and liability method which includes the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in our financial statements. Under this approach, deferred taxes are recorded for the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes represents income taxes paid or payable for the current year plus deferred taxes. Deferred taxes result from differences between the financial statements and tax bases of our assets and liabilities, and are adjusted for changes in tax rates and tax laws when changes are enacted. The effects of future changes in income tax laws or rates are not anticipated.

We are subject to corporation taxes in the United Kingdom and the United States. The calculation of our tax provision involves the application of U.K. tax law and requires judgement and estimates.

We evaluate the realizability of our deferred tax assets at each reporting date, and we establish a valuation allowance when it is more likely than not that all or a portion of our deferred tax assets will not be realized.

The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income of the same character and in the same jurisdiction. We consider all available positive and negative evidence in making this assessment, including, but not limited to, the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies. In circumstances where there is sufficient negative evidence indicating that our deferred tax assets are not more likely than not realizable, we establish a valuation allowance.

We use a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate tax positions taken or expected to be taken in a tax return by assessing whether they are more likely than not sustainable, based solely on their technical merits, upon examination, and including resolution of any related appeals or litigation process. The second step is to measure the associated tax benefit of each position as the largest amount that we believe is more likely than not realizable. Differences between the amount of tax benefits taken or expected to be taken in our income tax returns and the amount of tax benefits recognized in our financial statements represent our unrecognized income tax benefits, which we either record as a liability or as a reduction of deferred tax assets.

Deferred Tax and Current Tax Credits

Tax on the profit or loss for the year comprises current and deferred tax. Tax is recognized in the statement of operations, except to the extent that it relates to items recognized directly in equity, in which case it is recognized in equity. Current tax is the expected tax payable on the taxable income or loss for the year, using tax rates enacted or substantively enacted at the balance sheet date, and any adjustment to tax payable in respect of previous years. Tax credits are accrued for the year based on calculations that conform to the U.K. research and development tax credit regime, under both the SME and large company regimes. We meet the conditions of the SME regime, but also can make claims under the RDEC regime to the extent that our projects are grant funded.

We may not be able to continue to claim research and development tax credits under the SME regime in the future because we may no longer qualify as a small or medium-sized company. However, we should continue to be able to make claims under the RDEC regime.
Deferred tax is recognized on temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. The amount of deferred tax is based on the expected manner of realization or settlement of the carrying amount of assets and liabilities, using tax rates enacted or substantively enacted at the balance sheet date. A deferred tax asset is recognized only to the extent that it is probable that future taxable profits will be available against which the asset can be utilized. No deferred tax assets are recognized on our losses carried forward and other attributes because there is currently no indication that we will make sufficient profits to utilize these attributes.
JOBS Act
On April 5, 2012, the Jumpstart Our Business Startups Act, or the JOBS Act, was enacted. The JOBS Act provides that, among other things, an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. As an emerging growth company, we have irrevocably elected not to take advantage of the extended transition period afforded by the JOBS Act for implementation of new or revised accounting standards and, as a result, we will comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-emerging growth public companies.
In addition, we also currently rely on the other exemptions and reduced reporting requirements provided by the JOBS Act. Subject to certain conditions set forth in the JOBS Act, we are entitled to continue to rely on certain exemptions as an “emerging growth company,” and we are not required to, among other things, (i) provide an auditor’s attestation report on our system of internal controls over financial

reporting pursuant to Section 404(b), (ii) provide all of the compensation disclosure that may be required of non-emerging growth public companies under the Dodd-Frank Wall Street Reform and Consumer Protection Act, (iii) comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements (auditor discussion and analysis), and (iv) disclose certain executive compensation-related items such as the correlation between executive compensation and performance and comparisons of the chief executive officer’s compensation to median employee compensation. These exemptions will apply for a period of five years following the completion of our IPO or until we no longer meet the requirements of being an emerging growth company, whichever is earlier.
