Nature of business | Verastem, Inc. NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (unaudited)
Verastem, Inc. (the Company) is a biopharmaceutical company focused on discovering and developing drugs to improve the survival and quality of life of cancer patients. The Company’s operations to date have been limited to organizing and staffing the Company, business planning, raising capital, identifying and acquiring potential product candidates and undertaking preclinical and clinical studies of its product candidates. The Company is subject to a number of risks similar to other life science companies, including, but not limited to, the need to obtain adequate additional funding, possible failure of preclinical testing or clinical trials, inability to obtain marketing approval of product candidates, competitors developing new technological innovations, market acceptance of the Company’s products and protection of proprietary technology. If the Company does not successfully commercialize any of its product candidates, it will be unable to generate product revenue or achieve profitability. As of September 30, 2017, the Company had cash, cash equivalents and investments of $60.3 million and accumulated deficit of $284.9 million. The Company anticipates that it will continue to incur losses for the foreseeable future as it continues the research and development and clinical trials of, and seek marketing approval for, its lead product candidates. Without additional funding, the Company believes that it will not have sufficient funds to meet its obligations within the next twelve months from the date of issuance of these condensed consolidated financial statements. These factors raise substantial doubt about the Company’s ability to continue as a going concern.
The Company plans to continue to fund its operations through proceeds from sales of its common stock under its at-the-market offering program, public or private equity offerings, its loan and security agreement with Hercules Capital, Inc. (Hercules), public or private equity offerings, or other strategic transactions. However, adequate additional financing may not be available to the Company on acceptable terms, or at all. If the Company is unable to raise capital when needed or on attractive terms, it may be forced to delay, reduce or eliminate its research and development programs or any future commercialization efforts. |

Significant accounting policies |
2. Summary of significant accounting policies
Basis of Presentation
The accompanying unaudited condensed consolidated financial statements of 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 under the assumption that the Company will continue as a going concern for the next twelve months. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements, or any adjustments that might result from the uncertainty related to the Company’s ability to continue as a going concern. 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 nine months ended September 30, 2017 are not necessarily indicative of the results that may be expected for any other interim period or for the year ending December 31, 2017. 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, 2016 as filed with the Securities and Exchange Commission (SEC) on March 23, 2017.
Recently Issued Accounting Standards Updates
In May 2017, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2017-09, Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting. ASU 2017-09 provides guidance about which changes to the terms or conditions of a share-based award require an entity to apply modification accounting under Topic 718. Specifically, an entity would not apply modification accounting if the fair value, vesting conditions and classification of the awards are the same immediately before and after a modification. ASU 2017-09 is effective for annual and interim periods beginning after December 15, 2017, with early adoption permitted. The Company has not elected to early adopt this standard and does not expect the adoption to have a material impact on its consolidated financial statements and related disclosures.
In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. Amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. ASU 2016-18 is effective for annual and interim periods beginning after December 15, 2017, with early adoption permitted. The Company has not elected to early adopt this standard and does not expect the adoption to have a material impact on its consolidated financial statements and related disclosures.
In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. ASU 2016-15 adds or clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows. The standard is effective for annual and interim periods beginning after December 15, 2017, with early adoption permitted. The Company has not elected to early adopt this standard and does not expect the adoption to have a material impact on its consolidated financial statements and related disclosures. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), 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, with early adoption permitted. The Company has not elected to early adopt this standard and is currently evaluating the impact the adoption of the standard will have on its consolidated financial statements and related disclosures. Recently Adopted Accounting Standards Updates
In January 2017, the FASB issued ASU 2017-03, Accounting Changes and Error Corrections (Topic 250) and Investments – Equity Method and Joint Ventures (Topic 323): Amendments to SEC Paragraphs Pursuant to Staff Announcements at the September 22, 2016 and November 17, 2016 EITF Meetings. ASU 2017-03 clarifies the SEC staff’s expectations about the extent of disclosures that a registrant is expected to provide regarding the impact that the adoption of ASUs 2014-09 (Revenue from Contracts with Customers), 2016-02 (Leases) and 2016-13 (Measurement of Credit Losses on Financial Instruments) will have on its financial statements. It also conforms SEC guidance on accounting for tax benefits resulting from investments in affordable housing projects to the guidance in ASU 2014-01, Investments -Equity Method and Joint Ventures (Topic 323). The guidance under this ASU was effective upon issuance and did not have a material impact on the Company’s disclosures.
In October 2016, the FASB issued ASU 2016-17, Consolidation (Topic 810): Interests Held through Related Parties That Are under Common Control. ASU 2016-17 updates ASU 2015-02. Under the amendments, a single decision maker is not required to consider indirect interests held through related parties that are under common control with the single decision maker to be the equivalent of direct interests in their entirety. Instead, a single decision maker is required to include those interests on a proportionate basis consistent with indirect interests held through other related parties. ASU 2016-17 is effective for annual and interim periods beginning after December 15, 2016. The Company adopted this standard effective January 1, 2017. The adoption of this ASU did not have an effect on the Company’s financial statements or disclosures.
In March 2016, the FASB issued ASU 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 simplifies the accounting for share-based compensation arrangements, including the accounting for forfeitures, income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. The standard was effective for annual and interim periods beginning after December 15, 2016, with early adoption permitted. The Company adopted ASU 2016-09 effective January 1, 2017. Upon adoption, the Company elected to begin accounting for forfeitures as they occur, rather than estimating a forfeiture rate, and recorded an immaterial cumulative-effect adjustment to opening accumulated deficit. Also upon adoption, the Company recognized all previously unrecognized tax benefits, which would have resulted in the recognition of an immaterial cumulative-effect adjustment to opening accumulated deficit; however, these unrecognized tax benefits were recorded as a deferred tax asset, which was fully offset by a valuation allowance. Therefore, the recognition of these benefits had no net cumulative-effect on opening accumulated deficit upon adoption.
Significant accounting policies
There have been no material changes, other than those described above, to the significant accounting policies included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 as filed with the SEC on March 23, 2017.

Fair value of financial instruments | 3. 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:
Items Measured at Fair Value on a Recurring Basis
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. Government money market funds and corporate bonds and commercial paper of publicly traded companies. 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 September 30, 2017 and December 31, 2016.
Fair Value of Financial Instruments
The fair value of the Company’s long-term debt is determined using current applicable rates for similar instruments as of the balance sheet dates and an assessment of the credit rating of the Company. The carrying value of the Company’s debt approximates fair value because the Company’s interest rate yield is near current market rates for comparable debt instruments. The fair value of the Company’s long-term debt was determined using Level 3 inputs. |

Cash, cash equivalents and investments consist of the following (in thousands):
There were no realized gains or losses on investments for the three and nine months ended September 30, 2017 or 2016. There were no investments that had been in an unrealized loss position for more than 12 months as of September 30, 2017 or December 31, 2016. There were 2 debt securities in an unrealized loss position for less than 12 months at September 30, 2017 and there were 14 debt securities that had been in an unrealized loss position for less than 12 months at December 31, 2016. The aggregate unrealized loss on these securities as of September 30, 2017 and December 31, 2016 was approximately $400 and $24,000, respectively, and the fair value was $2.5 million and $23.6 million, respectively. The Company considered the decline in the market value for these securities to be primarily attributable to current economic conditions. As it was not more likely than not that the Company would be required to sell these securities before the recovery of their amortized cost basis, which may be at maturity, the Company did not consider these investments to be other-than-temporarily impaired as of September 30, 2017.

Long-term debt | 6. Long-term debt
On March 21, 2017 (Closing Date), Verastem, Inc. (Borrower) entered into a term loan facility of up to $25.0 million (Term Loan) with Hercules Capital, Inc., a Maryland corporation (Hercules), the proceeds of which have been and will be used for its ongoing research and development programs and for general corporate purposes. The Term Loan is governed by a loan and security agreement, dated March 21, 2017 (Loan Agreement), which provides for up to four separate advances subject to certain conditions of funding. The first tranche of $2.5 million was drawn on the Closing Date. On October 12, 2017, the Borrower drew an additional $7.5 million under the Loan Agreement, and used $6.0 million of the proceeds to make a milestone payment pursuant to the Company’s license agreement with Infinity Pharmaceuticals, Inc. (Infinity). See “Note 10. License Agreements” for additional information related to the milestone payment. The Term Loan will mature on December 1, 2020. Each advance accrues interest at a floating per annum rate equal to the greater of either (a) 10.5% or (b) the lesser of (i) 12.75% and (ii) the sum of (x) 10.5% plus (y) (A) the prime rate minus (B) 4.5%. As of September 30, 2017, the interest rate was 10.5%. The Term Loan provides for interest-only payments until November 1, 2018. The interest-only period may be extended to May 1, 2019 if the Borrower obtains minimum cash proceeds of $20.0 million from a sale of equity securities or subordinated debt and/or ongoing commercial partnerships. Thereafter, amortization payments will be payable monthly in twenty-six installments (or, if the period requiring interest-only payments has been extended to May 1, 2019, in twenty installments) of principal and interest (subject to recalculation upon a change in prime rates). The Term Loan is secured by a lien on substantially all of the assets of the Borrower, other than intellectual property, and contains customary covenants and representations. The Company assessed all terms and features of the Loan Agreement in order to identify any potential embedded features that would require bifurcation or any beneficial conversion features. As part of this analysis, the Company assessed the economic characteristics and risks of the Loan Agreement, including put and call features. The Company determined that all features of the Loan Agreement were clearly and closely associated with a debt host and did not require bifurcation as a derivative liability, or the fair value of the feature was immaterial to the Company's financial statements. The Company reassesses the features on a quarterly basis to determine if they require separate accounting. The future principal payments under the Loan Agreement are as follows as of September 30, 2017 (in thousands):

Stock options
A summary of the Company’s stock option activity and related information for the nine months ended September 30, 2017 is as follows:
The fair value of each stock option granted during the nine months ended September 30, 2017 and 2016 was estimated on the grant date using the Black-Scholes option-pricing model using the following weighted-average assumptions:
In June 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. In October 2016, the Company determined that 50% of performance conditions had been achieved and as a result 250,000 shares vested and the Company recognized stock-based compensation expense of approximately $222,000 for the year ended December 31, 2016. In September 2017, the Company determined that the remaining performance conditions had been achieved and as a result the remaining 250,000 shares vested and the Company recognized stock-based compensation expense of approximately $379,000 during the three months ended September 30, 2017. The increase in stock-based compensation expense recognized for the awards which vested during the three months ended September 30, 2017, as compared to the awards which vested during the year ended December 31, 2016, is a result of the revaluation of an award held by a non-employee to fair value on the vesting date.
Restricted stock units
The approximate total fair value of restricted stock units (RSUs) vested during the three and nine months ended September 30, 2016 was $0 and $65,000, respectively. As of September 30, 2016, all RSUs had vested and there was no remaining unrecognized stock-based compensation expense. There were no RSUs granted during or subsequent to the three and nine months ended September 30, 2016.
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. During the three and nine months ended September 30, 2016, the Company made approximate deposits with the taxing authorities of $0 and $5,000 in respect of the tax liability for awards that settled during the period. As of September 30, 2016, the Company had no remaining tax liability related to these awards. |

(Cantor), as sales agent. On August 28, 2017, the Company amended its sales agreement with Cantor to increase the maximum aggregate offering price of shares of common stock that can be sold under the at-the-market equity offering program to $75.0 million. Through September 30, 2017, the Company sold 2,853,753 shares under this program for net proceeds of approximately $14.1 million (after deducting commissions and other offering expenses).

X | ||||||||||
- Definition Cash includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the customer may deposit additional funds at any time and effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid Investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Short-term investments, exclusive of cash equivalents, generally consist of marketable securities intended to be sold within one year (or the normal operating cycle if longer) and may include trading securities, available-for-sale securities, or held-to-maturity securities (if maturing within one year), as applicable.
