2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”).

Segment Information

Operating segments are defined as components of an enterprise about which separate discrete information is available for evaluation by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. The Company views its operations and manages its business in one operating segment, which is the business of discovering, developing and commercializing drugs to treat cancer and certain other major diseases. All of the Company’s revenues are derived in the United States. All material long-lived assets of the Company reside in the United States.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.

 

On an ongoing basis, the Company’s management evaluates its estimates, including estimates related to clinical trial accruals, stock-based compensation expense, and reported amounts of revenues and expenses during the reported period. The Company bases its estimates on historical experience and other market-specific or other relevant assumptions that it believes to be reasonable under the circumstances. Although the Company regularly assesses these estimates, actual results could differ from those estimates. Changes in estimates are recorded in the period in which they become known.

Principles of Consolidation

The consolidated financial statements at December 31, 2014 include the accounts of Karyopharm Therapeutics Inc. (a Delaware corporation), the accounts of Karyopharm Securities Corp. (“KPSC”, a wholly-owned Massachusetts corporation of the Company incorporated in December 2013), and the accounts of Karyopharm Europe GmbH (a wholly-owned German Limited Liability Company, incorporated in September 2014). At December 31, 2013, the consolidated financial statements also included the accounts of NPM Pharma Inc. (“NPM”, a wholly-owned Canadian corporation of the Company). As of March 31, 2014, NPM transferred its remaining assets and liabilities to Karyopharm Therapeutics Inc. Following the transfer, NPM was dissolved. The dissolution of NPM had no effect on the consolidated financial statements. All intercompany balances and transactions have been eliminated in consolidation.

Cash and Cash Equivalents

Cash equivalents consist primarily of demand deposit accounts and deposits in short-term money market funds. Cash equivalents are stated at cost, which approximates fair market value. The Company considers all highly liquid investments with maturities of three months or less from the date of purchase to be cash equivalents.

Investments

The Company determines the appropriate classification of its investments in debt securities at the time of purchase. All of the Company’s securities are classified as available-for-sale and are reported in short-term investments or long-term investments based on maturity dates and whether such assets are reasonably expected to be realized in cash or sold or consumed during the normal cycle of business. Available-for-sale investments are recorded at fair value, with unrealized gains or losses included in Accumulated Other Comprehensive Loss on the Company’s Consolidated Balance Sheets, exclusive of other-than-temporary impairment losses, if any. Short-term and long-term investments are comprised of corporate debt securities, commercial paper, U.S. government agency securities and certificates of deposit.

Concentrations of Credit Risk and Off-Balance Sheet Risk

Financial instruments which potentially subject the Company to credit risk consist primarily of cash, cash equivalents and investment securities. The Company holds these investments in highly rated financial institutions, and, by policy, limits the amounts of credit exposure to any one financial institution. These amounts at times may exceed federally insured limits. The Company has not experienced any credit losses in such accounts and does not believe it is exposed to any significant credit risk on these funds. The Company has no off-balance sheet concentrations of credit risk, such as foreign currency exchange contracts, option contracts or other hedging arrangements.

Fair Value Measurements

The Company is required to disclose information on all assets and liabilities reported at fair value that enables an assessment of the inputs used in determining the reported fair values. The fair value hierarchy prioritizes valuation inputs based on the observable nature of those inputs. The fair value hierarchy applies only to the valuation inputs used in determining the reported fair value of the investments and is not a measure of the investment credit quality. The hierarchy defines three levels of valuation inputs:

 

Level 1 inputs Quoted prices in active markets for identical assets or liabilities
Level 2 inputs Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly

Level 3 inputs

Unobservable inputs that reflect the Company’s own assumptions about the assumptions market participants would use in pricing the asset or liability

The Company’s cash equivalents are comprised of money market funds. The Company measures these investments at fair value. The fair value of cash equivalents is determined based on “Level 1” inputs.

Items classified as Level 2 within the valuation hierarchy consist of commercial paper, corporate debt securities, U.S. government agency securities and certificates of deposit. The Company estimates the fair values of these marketable securities by taking into consideration valuations obtained from third-party pricing sources. These pricing sources utilize industry standard valuation models, including both income and market-based approaches, for which all significant inputs are observable, either directly or indirectly, to estimate fair value. These inputs include market pricing based on real-time trade data for the same or similar securities, issuer credit spreads, benchmark yields, and other observable inputs. The Company validates the prices provided by its third-party pricing sources by understanding the models used, obtaining market values from other pricing sources and analyzing pricing data in certain instances.

Property and Equipment, net

Property and equipment are recorded at cost, less accumulated depreciation. Depreciation is recorded using the straight-line method over the estimated useful lives of the respective assets, generally three to five years. Leasehold improvements are amortized over the shorter of the lease term or the estimated useful economic lives of the related assets. Expenditures for maintenance and repairs are charged to expense while the costs of significant improvements are capitalized. Upon retirement or sale, the cost of the assets disposed of and the related accumulated depreciation are eliminated from the balance sheets and any related gains or losses are reflected in the consolidated statements of operations.

Long-Lived Assets

The Company reviews the carrying values of its long-lived assets for possible impairment whenever events or changes in circumstances indicate that the carrying amounts of the assets may not be recoverable. Any long-lived assets held for disposal are reported at the lower of their carrying amounts or fair values less costs to sell. The Company has not recorded an impairment in any period since inception.

Deferred Rent

Deferred rent consists of rent escalation payment terms, tenant improvement allowances and other incentives received from landlords related to the Company’s operating leases. Rent escalation represents the difference between actual operating lease payments due and straight-line rent expense, which is recorded by the Company over the term of the lease. Tenant improvement allowances and other incentives are recorded as deferred rent and amortized as a reduction of periodic rent expense, over the term of the applicable lease.

Revenue Recognition

The Company recognizes revenue in accordance with the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) 605, Revenue Recognition. Accordingly, revenue is recognized for each unit of accounting when all of the following criteria are met:

 

    persuasive evidence of an arrangement exists;

 

    delivery has occurred or services have been rendered;

 

    the seller’s price to the buyer is fixed or determinable; and

 

    collectability is reasonably assured.

The Company recognizes revenue in accordance with the milestone method of revenue recognition for arrangements involving research or development or other performance obligations whereby a portion or all of the consideration is contingent upon achievement of milestone events. Under these provisions, arrangement consideration contingent upon achievement of a milestone is recognized by the Company in the period the milestone is met when the Company concludes that the milestone is substantive. At the inception of each applicable arrangement, the Company assesses each milestone and the consideration payable upon achievement of each milestone and concludes that the milestone is substantive if all of the following criteria are met: (i) the consideration is commensurate with the Company’s performance or the enhanced value of a delivered item which is a direct result of the Company’s performance to achieve the milestone, (ii) the consideration relates to past performance and there are no refund rights or other penalties related to the consideration based on completion of future performance and (iii) the consideration is reasonable relative to all the deliverables and payment terms within the arrangement. The related consideration for milestones that are considered substantive is recognized in its entirety in the period which the milestone is met.

The milestone method of revenue recognition was applicable to two research agreements which were executed during 2013 and 2011, respectively.

 

The agreement executed during 2013 includes payments upon the achievement of several development milestones as well as an upfront payment. The Company concluded that the upfront payment of $100 did not represent a substantive milestone. Accordingly, the Company is recognizing this amount on a straight-line basis from the date when substantive services commenced through the estimated completion of the final milestone. During the year ended December 31, 2013 the Company recognized $21 of the upfront payment and no additional milestones were met according to this research agreement. During the year ended December 31, 2014, the Company recognized $229 related to this agreement, including $79 of the upfront payment and $150 related to other milestones associated with the agreement. The Company could earn additional milestones of up to $250 under this agreement.

The agreement executed during 2011 includes payments upon the achievement of several development milestones as well as an upfront payment. The Company concluded that the upfront payment of $200 did not represent a substantive milestone. Accordingly, the Company recognized this amount on a straight-line basis from the date when substantive services commenced through the estimated completion of the final milestone. During the year ended December 31, 2012, the Company recognized $634 related to this research agreement, including $134 of the upfront payment. During the year ended December 31, 2013, the Company recognized $366 related to this agreement, including $66 related to the upfront payment and $300 related to other milestones associated with the agreement. There are no future milestones to be met under this agreement. The Company did not recognize revenue under this agreement during the year ended December 31, 2014.

Research and Development Expenses

Research and development costs are charged to expense as incurred and include, but are not limited to:

 

    employee-related expenses, including salaries, benefits, travel and stock-based compensation expense;

 

    expenses incurred under agreements with contract research organizations, contract manufacturing organizations and consultants that conduct clinical trials and preclinical studies;

 

    the cost of acquiring, developing and manufacturing clinical trial materials;

 

    facility, depreciation and other expenses, which include direct and allocated expenses for rent and maintenance of facilities, insurance and other supplies; and

 

    costs associated with preclinical activities and regulatory operations.

Costs for certain development activities, such as clinical trials, are recognized based on an evaluation of the progress to completion of specific tasks using data such as patient enrollment, clinical site activations, or information provided to the Company by its vendors on their actual costs incurred. Payments for these activities are based on the terms of the individual arrangements, which may differ from the pattern of costs incurred, and are accordingly reflected in the financial statements as prepaid or accrued research and development.

Comprehensive Loss

Comprehensive loss consists of net loss and changes in equity during a period from transactions and other equity and circumstances generated from non-owner sources, and currently consists of net loss, unrealized losses on investments and foreign currency translation adjustments.

Foreign Currency Transactions

The functional currency of the Company’s subsidiary in Germany is the Euro. Foreign currency transaction gains and losses are recorded in the consolidated statement of operations. Net foreign exchange losses of $27 were recorded in other expense for the year ended December 31, 2014. There were no foreign exchange gain or loss for the years ended December 31, 2013 and 2012.

 

Income Taxes

The Company uses the liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial reporting and the tax reporting basis of assets and liabilities and are measured using the enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse. The Company provides a valuation allowance against net deferred tax assets unless, based upon the available evidence, it is more likely than not that the deferred tax assets will be realized. The Company has evaluated available evidence and concluded that the Company may not realize the benefit of its deferred tax assets; therefore a valuation allowance has been established for the full amount of the deferred tax assets. The Company recognizes interest and/or penalties related to income tax matters in income tax expense.

Accounting for Stock-Based Compensation

The Company accounts for its stock-based compensation awards in accordance with FASB ASC Topic 718, Compensation—Stock Compensation (“ASC 718”). ASC 718 requires all stock-based payments to employees, including grants of employee stock options and restricted stock and modifications to existing stock options, to be recognized in the consolidated statements of operations based on their fair values. The Company uses the Black-Scholes option pricing model to determine the fair value of options granted.

Consistent with the guidance in FASB ASC Topic 505-50, Equity-Based Payments to Non-Employees, the fair value of each non-employee stock option is estimated at the date of grant using the Black-Scholes option pricing model with assumptions generally consistent with those used for employee stock options, with the exception of expected term, which is over the contractual life.

Compensation expense related to awards to employees is recognized on a straight-line basis based on the grant date fair value over the requisite service period of the award, which is generally the vesting term. Stock-based compensation expense for awards granted to non-employees is adjusted as the award vests to reflect the current fair value of such awards, and is recognized using an accelerated attribution model.

Net Loss Per Share

Basic and diluted net loss per common share is calculated by dividing net loss applicable to common stockholders by the weighted-average number of common shares outstanding for the period, without consideration for common stock equivalents. The Company’s potential dilutive shares, which include convertible preferred stock, special participation stock, outstanding stock options and unvested restricted stock are considered to be common stock equivalents and are only included in the calculation of diluted net loss per share when their effect is dilutive.

The following potentially dilutive securities were excluded from the calculation of diluted net loss per share due to their anti-dilutive effect at December 31, 2014, 2013 and 2012 (in common stock equivalent shares):

 

     December 31,  
     2014      2013      2012  

Convertible preferred stock

     —           —           5,587,121   

Special participation stock

     —           —           10,000   

Outstanding stock options

     3,012,923         2,410,522         691,367   

Unvested restricted stock

     11,410         166,949         541,218   

Recently Issued Accounting Pronouncements

In May 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which supersedes the revenue recognition requirements in Accounting Standards Codification Topic 605, Revenue Recognition and most industry-specific guidance. The new standard requires that an entity recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The update also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. ASU 2014-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016 and should be applied retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying this update recognized at the date of initial application. The Company has not yet determined the potential effects of the adoption of this standard on its consolidated financial position, results of operations or cash flows.

On June 10, 2014, the FASB issued ASU 2014-10, which simplifies financial reporting for development stage entities by eliminating requirements specific to development stage entities. As a result, entities in a development stage will no longer need to present inception-to-date information about income statement line items, cash flows, and equity transactions. Instead, the new guidance clarifies how these entities should tailor existing disclosures to explain the risks and uncertainties related to their activities. This update is effective for annual periods beginning after December 15, 2014, and early application is permitted for any annual or interim period for which the entity’s financial statements have not yet been issued. The Company adopted this guidance prior to issuing the interim financial statements for the three and six months ended June 30, 2014. The adoption of ASU 2014-10 impacted disclosure only and did not have any impact on the Company’s financial position or results of operations.

In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. ASU No. 2014-15 is intended to define management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. Substantial doubt about an entity’s ability to continue as a going concern exists when relevant conditions and events, considered in the aggregate, indicate that it is probable that the entity will be unable to meet its obligations as they become due within one year after the date that the financial statements are issued (or available to be issued). ASU No. 2014-15 provides guidance to an organization’s management, with principles and definitions that are intended to reduce diversity in the timing and content of disclosures that are commonly provided by organizations in the financial statement footnotes. ASU No. 2014-15 is effective for annual reporting periods ending after December 15, 2016, and to annual and interim periods thereafter. Early adoption is permitted. The Company is currently in the process of evaluating the impact of adoption of ASU No. 2014-15 on its consolidated financial statements and related disclosures.
