2. Summary of Significant Accounting Policies

Basis of Preparation

The unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“US GAAP”) for interim financial information and U.S. Securities and Exchange Commission (“SEC”) regulations for quarterly reporting.

The accompanying consolidated financial information as of September 30, 2017 and for the three and nine months ended September 30, 2016 and 2017 is unaudited. The December 31, 2016 condensed balance sheet data was derived from audited consolidated financial statements but does not include all disclosures required by US GAAP. The interim unaudited consolidated financial statements have been prepared on the same basis as the annual audited consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for the fair statement of the Company’s financial position as of September 30, 2017 and for the three and nine months ended September 30, 2016 and 2017. The financial data and other information disclosed in these notes related to the three and nine months ended September 30, 2016 and 2017 are not necessarily indicative of the results to be expected for the year ending December 31, 2017, any other interim periods or any future year or period. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto for the year ended December 31, 2016 contained in the Company’s Annual Report on Form 10-K, as filed with the SEC on March 24, 2017.

The Company’s significant accounting policies are described in Note 2 of the notes to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. Since the date of those financial statements, there have been no changes to the Company’s significant accounting policies.

Recent Accounting Pronouncements

From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) or other standard setting bodies that the Company adopts as of the specified effective date.

Adopted as of the current period:

In November 2015, the FASB issued Accounting Standards Update (“ASU”) 2015-17, Income Taxes: Balance Sheet Classification of Deferred Taxes. ASU 2015-17 simplifies the balance sheet classification of deferred taxes and requires that all deferred taxes be presented as noncurrent. ASU 2015-17 was effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. The impact of adopting this standard did not have a material effect on the Company’s financial position, results of operation or cash flow and related disclosures.

In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 provides for simplification of certain aspects of employee share-based payment accounting including income taxes, classification of awards as either equity or liabilities, accounting for forfeitures and classification on the statement of cash flows. ASU 2016-09 was effective for the fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. The impact of adopting this standard did not have a material effect on the Company’s financial position, results of operation or cash flow and related disclosures.

To be adopted in future periods:

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, an updated standard on revenue recognition. ASU 2014-09 provides enhancements to the quality and consistency of how revenue is reported by companies while also improving comparability in the financial statements of companies reporting using International Financial Reporting Standards or US GAAP. The main purpose of the new standard is for companies to recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the consideration to which a company expects to be entitled in exchange for those goods or services. The new standard also will result in enhanced revenue disclosures, provide guidance for transactions that were not previously addressed comprehensively and improve guidance for multiple-element arrangements. In July 2015, the FASB voted to approve a one-year deferral of the effective date of ASU 2014-09, which will be effective for the Company in the first quarter of fiscal year 2018 and may be applied on a full retrospective or modified retrospective approach. ASU 2014-09 will have no impact on the Company until it begins to generate product revenue.

In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01 amends certain aspects of accounting and disclosure requirements of financial instruments, including the requirement that equity investments with readily determinable fair values be measured at fair value with changes in fair value recognized in the results of operations. ASU 2016-01 is effective for annual periods beginning after December 15, 2017, and interim periods within those fiscal years. The Company does not anticipate the initial adoption of the provisions of this guidance will have a material impact on its financial position, results of operation or cash flow and related disclosures.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). ASU 2016-02 establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. ASU 2016-02 is effective for annual periods beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted. A modified retrospective transition approach is required for lessees of capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company is currently evaluating the impact that the standard will have on its financial position, results of operation or cash flow and related disclosures.

In May 2017, the FASB issued ASU 2017-09, Compensation—Stock Compensation: Scope of Modification Accounting. ASU 2017-09 clarifies which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718, Compensation—Stock Compensation. ASU 2017-09 is effective for annual periods beginning after December 15, 2017, and interim periods within those years. Early adoption is permitted. An entity should apply the amendments prospectively to a modification that occurs on or after the adoption date. The Company does not anticipate the initial adoption of the provisions of this guidance to have a material impact on its financial position, results of operation or cash flow and related disclosures.
