Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and the notes thereto. On an ongoing basis, Management evaluates its estimates related to, but not limited to, the useful lives of property and equipment, the recoverability of long-lived assets, preclinical and clinical trial accruals, the measurement of the Series D 2X liquidation preference, assumptions used in estimating the fair value of warrants issued to Invesco Asset Managementto (the Invesco Warrants), assumptions used in estimating the fair value of stock-based compensation expense and other contingencies. The Company’s assumptions regarding the measurement of the Series D 2X liquidation preference and stock-based compensation are more fully described in Note 5 — Fair Value of Financial Instruments and Note 10 — Stock-based Compensation, respectively. 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 and adjusts when facts and circumstances dictate. The estimates are the basis for making judgments about the carrying values of assets and liabilities and recorded expenses that are not readily apparent from other sources. As future events and their effects cannot be determined with precision, actual results may materially differ from those estimates or assumptions. Segment Reporting Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision-maker in making decisions regarding resource allocation and assessing performance. The Company views its operations and manages its business in one operating segment. Concentrations of Credit Risk Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash and restricted cash. Deposits in the Company’s checking and time deposit accounts are maintained in federally insured financial institutions in excess of federally insured limits. The Company invests in funds through a major U.S. bank and is exposed to credit risk in the event of default to the extent of amounts recorded on the consolidated balance sheets. The Company has not experienced any losses in such accounts and believes it is not exposed to significant concentrations of credit risk on its cash, cash equivalents and restricted cash balances due to the financial position of the depository institutions in which these deposits are held. Significant Accounting Policies The Company's significant accounting policies are more fully described in Note 2 to the 2017 Audited Financial Statements. There have been no changes to the significant accounting policies during the first three months of fiscal year 2018. Cash, Cash Equivalents and Restricted Cash Cash and cash equivalents consists of readily available cash in checking and money market accounts. Restricted cash consists of cash held in monthly time deposit accounts, which are collateral for the Company’s credit cards and facility leases. The following table provides a reconciliation of cash, cash equivalents and restricted cash, reported within the condensed consolidated statements of cash flows (in thousands):
Net Loss Per Share Basic net loss per common share is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period, without consideration for potentially dilutive securities. Diluted net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted-average number of common shares and potentially dilutive securities outstanding for the period determined using the treasury-stock and if-converted methods. For purposes of the diluted net loss per share calculation, potentially dilutive securities are excluded from the calculation of diluted net loss per share because their effect would be anti-dilutive and therefore, basic and diluted net loss per share were the same for all periods presented. Potentially dilutive securities excluded from the calculation of diluted net loss per share are summarized in the table below. For the three months ended March 31, 2017, the shares in the table have been adjusted to reflect the conversion of Series A, B, C-1, and C convertible preferred stock and Series D redeemable convertible preferred stock (Series D) into the common stock as fully described in Note 8- Convertible Preferred Stock, and the Reverse Stock Split.
Recently Adopted Accounting Pronouncements The Company qualifies as an “emerging growth company” (EGC) pursuant to the provisions of the Jumpstart Our Business Startups (JOBS) Act. Section 7(a)(2)(B) of the Securities Act of 1933, as amended, permits EGCs to defer compliance with new or revised accounting standards until non-issuers are required to comply with such standards. However, the Company elected not to take advantage of the extended transition period for implementation of new or revised financial accounting standards, and as a result, the Company will comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-emerging growth companies. In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606) (ASU No. 2014-09), which amends the existing accounting standards for revenue recognition. ASU No. 2014-09 is based on principles that govern the recognition of revenue at an amount an entity expects to be entitled when products are transferred to customers. The new standard as amended by ASU No. 2015-14, ASU No. 2016-10 and ASU No. 2016-12 was effective for the Company beginning January 1, 2018. The Company adopted the new standard using the full retrospective approach, which did not have an impact on the Company’s financial position or results of operations as the Company is pre-revenue and does not anticipate generating any significant revenue prior to 2020. In May 2017, the FASB issued ASU No. 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting (ASU No. 2017-09), which clarifies when to account for a change to the terms or conditions of a share-based payment award as a modification. Under the new guidance, modification accounting is required only if the fair value, the vesting conditions, or the classification of the award (as equity or liability) changes as a result of the change in terms or conditions. ASU No. 2017-09 was effective for the Company beginning January 1, 2018. The adoption of this new standard did not have a material impact on the Company’s financial position or results of operations. Recently Issued Accounting Pronouncements — Not Yet Adopted In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (ASU No. 2016-02), which changes the presentation of assets and liabilities relating to leases. The core principle of ASU No. 2016-02 is that a lessee should recognize the assets and liabilities that arise from leases. All leases create an asset and a liability for the lessee in accordance with FASB Concepts Statement No. 6, Elements of Financial Statements, and, therefore, recognition of those lease assets and lease liabilities represents an improvement over previous GAAP, which did not require lease assets and lease liabilities to be recognized for most leases. The new standard as amended by ASU No. 2018-01 will be effective for the Company beginning January 1, 2019. The Company’s 2015 Lease will expire in 2020 (see Note 6 — Commitments and Contingencies for details of the 2015 Lease) and be subject to the provisions of this new standard. The Company is in the process of assessing the impact of the new standard on its consolidated financial statements. |
