Significant accounting policies | Verastem, Inc. NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (unaudited)
1. Summary of significant accounting policies
Basis of presentation
The accompanying unaudited condensed consolidated financial statements of Verastem, Inc. (the Company) have been prepared in accordance with generally accepted accounting principles in the United States (GAAP) for interim financial reporting and as required by Regulation S-X, Rule 10-01. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (including those which are normal and recurring) considered necessary for a fair presentation of the interim financial information have been included. When preparing financial statements in conformity with GAAP, the Company must make estimates and assumptions that affect the reported amounts and related disclosures at the date of the financial statements. Actual results could differ from those estimates. Additionally, operating results for the three and six months ended June 30, 2016 are not necessarily indicative of the results that may be expected for any other interim period or for the fiscal year ending December 31, 2016. For further information, refer to the financial statements and footnotes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 as filed with the SEC on March 3, 2016.
Recent accounting pronouncements
Employee share-based payments
In March 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-09, Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 simplifies the accounting for share-based compensation arrangements, including the income tax impact and classification on the statement of cash flows. The standard is effective for annual and interim periods beginning after December 15, 2016. Early adoption is permitted. The Company is currently evaluating the impact the adoption of this standard will have on its consolidated financial statements and related disclosures. Leases In February 2016, the FASB issued ASU 2016-02, Leases, which supersedes the guidance under FASB Accounting Standards Codification (ASC) Topic 840, Leases, resulting in the creation of FASB ASC Topic 842, Leases. ASU 2016-02 requires lessees to recognize in the statement of financial position a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term for both finance and operating leases. The guidance also eliminates the current real estate-specific provisions for all entities. ASU 2016-02 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. Early adoption is permitted. The Company has not chosen early adoption for this ASU and is currently evaluating its effect on its consolidated financial statements. Going concern In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements - Going Concern: Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern (Subtopic 205-40). ASU 2014-15 requires management to assess an entity’s ability to continue as a going concern every reporting period, and provide certain disclosures if management has substantial doubt about the entity’s ability to operate as a going concern, or an express statement if not, by incorporating and expanding upon certain principles that are currently in U.S. auditing standards. ASU 2014-15 is effective for the interim and annual periods after December 15, 2016. Early adoption is permitted. The Company has evaluated the impact of the adoption of ASU 2014-15 on its three and six months ended June 30, 2016 consolidated financial statements and determined that there is not substantial doubt about the Company’s ability to continue as a going concern for at least one year from the issuance of the three and six months ended June 30, 2016 consolidated financial statements.
Significant accounting policies
There have been no changes to the Company’s significant accounting policies included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 as filed with the SEC on March 3, 2016.

Fair value of financial instruments | 2. Fair value of financial instruments
The Company determines the fair value of its financial instruments based upon the fair value hierarchy, which 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:
The following table presents information about the Company’s financial instruments that are measured at fair value on a recurring basis (in thousands):
The Company’s cash equivalents and investments are comprised of U.S. Treasury money market funds, U.S. Treasury securities, government-sponsored enterprise securities, repurchase agreements collateralized by government agency securities or U.S. Treasury securities, and corporate bonds and commercial paper. These investments have been initially valued at the transaction price and subsequently valued, at the end of each reporting period, utilizing third party pricing services or other market observable data. The pricing services utilize industry standard valuation models, including both income and market based approaches and observable market inputs to determine value. These observable market inputs include reportable trades, benchmark yields, credit spreads, broker/dealer quotes, bids, offers, current spot rates and other industry and economic events. The Company validates the prices provided by third party pricing services by reviewing their pricing methods and matrices, obtaining market values from other pricing sources, analyzing pricing data in certain instances and confirming that the relevant markets are active. After completing its validation procedures, the Company did not adjust or override any fair value measurements provided by the pricing services as of June 30, 2016 and December 31, 2015.
The Company’s liability classified stock-based compensation awards are comprised of restricted stock units (RSUs) that allow for greater than minimum statutory tax withholdings. These awards are valued based on the fair value of the Company’s common stock underlying the awards, which is traded on an active market. During the first quarter of 2013, the Company amended the terms of certain RSUs to allow for cash tax withholdings greater than the minimum required statutory withholding amount. As a result of this change in the terms of the awards, the outstanding RSUs are considered to be liability instruments. As a result of this modification, the Company records a liability for the fair value of the awards as of each reporting date with the change in fair value recorded through the statement of operations. The Company recorded stock-based compensation expense equal to the greater of the original grant date fair value of the awards or the settlement date fair value. All such RSUs were fully vested as of February 1, 2016. During the three and six months ended June 30, 2016 and 2015, the Company made approximate deposits to the taxing authorities of $0, $5,000, $30,000 and $253,000, respectively, to settle the tax liability for awards that settled during such periods.

Investments | 3. Investments
The Company’s investments are classified as available-for-sale pursuant to the accounting standards for investments in debt and equity securities. The Company classifies investments available to fund current operations as current assets on its balance sheets. Investments are classified as long-term assets on the balance sheets if (i) the Company has the intent and ability to hold the investments for a period of at least one year and (ii) the contractual maturity date of the investments is greater than one year.
Investments are carried at fair value with unrealized gains and losses included as a component of accumulated other comprehensive (loss) income, until such gains and losses are realized. If a decline in the fair value is considered other‑than‑temporary, based on available evidence, the unrealized loss is transferred from other comprehensive loss to the statement of operations. There were no charges taken for other‑than‑temporary declines in fair value of short-term or long-term investments during the three and six months ended June 30, 2016 and 2015. The Company recorded approximate unrealized (losses) gains of $(58,000), $34,000, $(7,000) and $21,000 during the three and six months ended June 30, 2016 and 2015, respectively. Realized gains and losses are included in interest income in the statement of operations. There were no realized gains or losses recognized during the three and six months ended June 30, 2016 and 2015. The Company utilizes the specific identification method as a basis to determine the cost of securities sold.
The Company reviews investments for other‑than‑temporary impairment whenever the fair value of an investment is less than the amortized cost and evidence indicates that an investment’s carrying amount is not recoverable within a reasonable period of time. To determine whether an impairment is other‑than‑temporary, the Company considers the intent to sell, or whether it is more likely than not that the Company will be required to sell, the investment before recovery of the investment’s amortized cost basis. Evidence considered in this assessment includes reasons for the impairment, compliance with the Company’s investment policy, the severity and the duration of the impairment and changes in value subsequent to year end. As of June 30, 2016, there were no investments with a fair value that was significantly lower than the amortized cost basis or any investments that had been in an unrealized loss position for a significant period.

Net loss per share | 5. Net loss per share
Basic and diluted net loss per common share is calculated by dividing net loss by the weighted-average number of common shares outstanding during the period, without consideration for common stock equivalents. The Company’s potentially dilutive shares, which include outstanding stock options and unvested restricted stock units, and the warrant issued in 2014 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 for the periods indicated because including them would have had an anti-dilutive effect:

6. Stock‑based compensation
In December 2011, the Company adopted the 2012 Incentive Plan (the 2012 Plan). The 2012 Plan became effective upon the closing of the Company’s IPO in February 2012. The 2012 Plan provides for the grant of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock awards, restricted stock units and other stock‑based and cash awards. Upon effectiveness, the number of shares of common stock that are reserved under the 2012 Plan is the sum of 3,428,571 shares plus the number of shares available under the Company’s prior 2010 Plan. The number of shares reserved under the 2012 Plan is increased by the number of shares of common stock (up to a maximum of 571,242 shares) subject to outstanding awards under the 2010 Plan that expire, terminate or are otherwise surrendered, cancelled, forfeited or repurchased. The 2012 Plan includes an “evergreen provision” that allows for an annual increase in the number of shares of common stock available for issuance under the 2012 Plan. The annual increase will be added on the first day of each year beginning in 2013 and each subsequent anniversary until the expiration of the 2012 Plan, equal to the lowest of 1,285,714 shares of common stock, 4.0% of the number of shares of common stock outstanding and an amount determined by the board of directors. On January 1, 2016 and 2015, the shares available under the 2012 Plan increased by 1,285,714 and 1,081,045 shares of common stock, respectively.
In December 2014, the Company established an inducement award program (in accordance with NASDAQ Listing Rule 5635(c)(4)) under which it may grant non-statutory stock options to purchase up to an aggregate of 750,000 shares of common stock to new employees as inducement for prospective employees to enter into employment with the Company. The program is governed by the terms of the 2012 Plan but the shares are not issued pursuant to the 2012 Plan. The Company has granted 580,000 and 210,000 options to purchase shares under this program as of June 30, 2016 and 2015, respectively. As of June 30, 2016, 75,000 of the options issued under this program have been cancelled.
Restricted common stock
No restricted common stock was granted during the three and six months ended June 30, 2016 and 2015. The total fair value of shares vested during the three and six months ended June 30, 2015 was $0 and approximately $59,000, respectively. All issued awards were fully vested as of December 31, 2015.
Restricted stock units
A summary of the Company’s RSU activity and related information for the six months ended June 30, 2016 is as follows:
No RSUs were granted during the three and six months ended June 30, 2016 and 2015. The approximate total fair value of RSUs vested during the three and six months ended June 30, 2016 and 2015 was $0, $65,000, $63,000 and $936,000, respectively. As of June 30, 2016, there was no unrecognized stock-based compensation expense related to unvested RSUs granted under the 2012 Plan.
During the first quarter of 2013, the Company amended the terms of certain RSUs related to a total of 697,060 shares of common stock to allow for tax withholdings greater than the minimum required statutory withholding amount. As a result of this change in the terms of the awards, the outstanding RSUs were considered to be liability instruments. As a result of this modification, the Company recorded a liability for the fair value of the awards as of each reporting date with the change in fair value recorded through the statement of operations. The Company recorded stock‑based compensation expense equal to the greater of the original grant date fair value of the awards or the settlement date fair value. All such RSUs were fully vested as of February 1, 2016. During the three and six months ended June 30, 2016 and 2015, the Company made approximate deposits with the taxing authorities of $0, $5,000, $30,000 and $253,000, respectively, in respect of the tax liability for awards that settled during such periods.
Stock options
During the second quarter of 2016, the Company granted stock options to purchase a total of 500,000 shares of common stock to certain employees that vest only upon the achievement of specified performance conditions. The grant date fair value of these options is approximately $445,000. The Company has determined that none of the performance conditions are considered probable of achievement as of June 30, 2016 and as a result, has not recognized any stock-based compensation expense related to these awards.
A summary of the Company’s stock option activity and related information for the six months ended June 30, 2016 is as follows:
The fair value of each stock option is estimated on the grant date using the Black-Scholes option-pricing model using the following weighted average assumptions:

1. Summary of significant accounting policies
Basis of presentation
The accompanying unaudited condensed consolidated financial statements of Verastem, Inc. (the Company) have been prepared in accordance with generally accepted accounting principles in the United States (GAAP) for interim financial reporting and as required by Regulation S-X, Rule 10-01. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (including those which are normal and recurring) considered necessary for a fair presentation of the interim financial information have been included. When preparing financial statements in conformity with GAAP, the Company must make estimates and assumptions that affect the reported amounts and related disclosures at the date of the financial statements. Actual results could differ from those estimates. Additionally, operating results for the three and six months ended June 30, 2016 are not necessarily indicative of the results that may be expected for any other interim period or for the fiscal year ending December 31, 2016. For further information, refer to the financial statements and footnotes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 as filed with the SEC on March 3, 2016.
Recent accounting pronouncements
Employee share-based payments
In March 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-09, Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 simplifies the accounting for share-based compensation arrangements, including the income tax impact and classification on the statement of cash flows. The standard is effective for annual and interim periods beginning after December 15, 2016. Early adoption is permitted. The Company is currently evaluating the impact the adoption of this standard will have on its consolidated financial statements and related disclosures. Leases In February 2016, the FASB issued ASU 2016-02, Leases, which supersedes the guidance under FASB Accounting Standards Codification (ASC) Topic 840, Leases, resulting in the creation of FASB ASC Topic 842, Leases. ASU 2016-02 requires lessees to recognize in the statement of financial position a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term for both finance and operating leases. The guidance also eliminates the current real estate-specific provisions for all entities. ASU 2016-02 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. Early adoption is permitted. The Company has not chosen early adoption for this ASU and is currently evaluating its effect on its consolidated financial statements. Going concern In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements - Going Concern: Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern (Subtopic 205-40). ASU 2014-15 requires management to assess an entity’s ability to continue as a going concern every reporting period, and provide certain disclosures if management has substantial doubt about the entity’s ability to operate as a going concern, or an express statement if not, by incorporating and expanding upon certain principles that are currently in U.S. auditing standards. ASU 2014-15 is effective for the interim and annual periods after December 15, 2016. Early adoption is permitted. The Company has evaluated the impact of the adoption of ASU 2014-15 on its three and six months ended June 30, 2016 consolidated financial statements and determined that there is not substantial doubt about the Company’s ability to continue as a going concern for at least one year from the issuance of the three and six months ended June 30, 2016 consolidated financial statements.
