Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

In addition to the policies below, the Company's significant accounting policies are described in Note 2 of the Notes to Consolidated Financial Statements included in its 2019 Form 10-K. There were no changes to these policies during the three and six months ended June 30, 2020.

Concentration of Risks

        The Company is subject to credit risk from its portfolio of cash, cash equivalents and marketable securities. Under its investment policy, the Company limits amounts invested in such securities by credit rating, maturity, industry group, investment type and issuer, except for securities issued by the U.S. government. Cash is held at major banks in the United States. Therefore, the Company is not exposed to any significant concentrations of credit risk from these financial instruments. The goals of the Company's investment policy, in order of priority, are as follows: safety and preservation of principal and diversification of risk, liquidity of investments sufficient to meet cash flow requirements, and a competitive after-tax rate of return.

Share-Based Compensation  

The Company expenses all share-based payment awards to employees, directors, and consultants, including grants of stock options, warrants, and restricted stock, over the requisite service period based on the grant date fair value of the awards. Consultant awards are remeasured each reporting period through vesting. For awards with performance-based vesting criteria, the Company estimates the probability of achievement of the performance criteria and recognizes compensation expense related to those awards expected to vest. The Company determines the fair value of option awards using the Black-Scholes option-pricing model which uses both historical and current market data to estimate the fair value. This method incorporates various assumptions such as the risk-free interest rate, expected volatility, expected dividend yield and expected life of the options or warrants. The fair value of the Company’s restricted stock and restricted stock units is based on the closing market price of the Company’s common stock on the date of grant.

New Accounting Pronouncements

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). ASU 2016-02 requires that a lessee recognize lease assets and lease liabilities for those leases classified as operating leases. The guidance was effective for interim and annual periods beginning after December 15, 2018 and was adopted as of January 1, 2019. The Company adopted the standard using the modified retrospective transition method, with an immaterial adjustment to accumulated deficit upon adoption. The comparative information has not been restated and continues to be reported under the accounting standards that were in effect

for those periods. The Company concluded that the adoption of ASU 2016-02 was non-cash in nature, did not affect the Company's cash position, and did not have a material impact on the Company's consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses, which will require companies to present assets held at amortized cost and available for sale debt securities net of the amount expected to be collected. The guidance requires the measurement of expected credit losses to be based on relevant information from past events, including historical experiences, current conditions and reasonable and supportable forecasts that affect collectability. The guidance was effective for fiscal years and interim periods beginning after December 15, 2019 and early adoption was permitted. The adoption of this guidance did not have a material impact on the Company's consolidated financial statements.

In June 2018, the FASB issued ASU 2018-07, "Improvements to Nonemployee Share-Based Payment Accounting," which supersedes ASC 505-50 and expands the scope of ASC 718 to include all share-based payments arrangements related to the acquisition of goods and services from both employees and nonemployees. For public companies, the amendments are effective for annual reporting periods beginning after December 15, 2018, including interim periods within those annual periods. Early adoption was permitted, but no earlier than a company's adoption date of ASC 606. The Company determined that the adoption of this new accounting guidance did not have a material impact on its consolidated financial statements and footnote disclosures.

In July 2019, the FASB issued ASU 2019-07, "Codification Updates to SEC Sections", to codify the SEC releases that clarify and improve the disclosure and presentation requirements of a variety of codification topics, thereby eliminating certain disclosure requirements that were redundant, duplicative, overlapping, outdated, or superseded. The Company determined that the adoption of this new accounting guidance did not have a material impact on its consolidated financial statements and footnote disclosures.

In October 2019, the FASB issued ASU 2019-12, which affects general principles within Topic 740, Income Taxes. The amendments of ASU 2019-12 are meant to simplify and reduce the cost of accounting for income taxes. For public business entities, the amendments in this Update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. The Company believes that the adoption of this new accounting guidance will not have a material impact on its financial statements and footnote disclosures.
