| Summary of Significant Accounting Policies |
Summary of Significant Accounting Policies Other than discussed below, there have been no material changes to our significant accounting policies as compared to those described in our Annual Report on Form 10-K for the year ended December 31, 2016.
Stock-Based Compensation—Restricted Stock Units and Stock Options
Stock-based awards granted to employees, including grants of restricted stock units ("RSUs") and stock options, are recognized as expense in our statements of operations based on their grant date fair value. We recognize stock-based compensation expense on a straight-line basis over the service period of the award, which is generally three to four years. We estimate the fair value of RSUs at our stock price on the grant date. We generally estimate the grant date fair value of stock options using the Black-Scholes option-pricing model. The Black-Scholes option-pricing model is affected by our stock price on the date of grant, the expected stock price volatility over the expected term of the award, which is based on projected employee stock option exercise behaviors, the risk-free interest rate for the expected term of the award and expected dividends.
Stock-based compensation expense is recorded in the statement of operations for only those stock-based awards that will vest. In the first quarter of 2017 we adopted new accounting guidance from the Financial Accounting Standards Board ("FASB") on stock compensation, or ASU 2016-09, as described in "Recently Adopted Accounting Standards" below and have elected to account for forfeitures as they occur, rather than estimating expected forfeitures. In addition, we recognize all income tax effects of awards in the income statement when the awards vest or are settled as required by ASU 2016-09.
Net Loss per Common Share
Basic net loss per common share is computed by dividing the net loss available to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per common share is computed by giving effect to all potential shares of common stock, including stock options, restricted stock units, market stock units, performance-based RSUs, potential ESPP shares and instruments convertible into common stock, to the extent dilutive. Basic and diluted net loss per common share were the same for each period presented as the inclusion of all potential common shares outstanding would have been anti-dilutive.
Concentration of Credit Risk
For the three and nine months ended September 30, 2016 and 2017, we had no customers that accounted for more than 10% of our total revenue. As of December 31, 2016 and September 30, 2017, we had no customers that accounted for more than 10% of our total accounts receivable.
Recently Issued Accounting Standards
In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"), which amends the existing accounting standards for revenue recognition. ASU 2014-09 outlines a single comprehensive model for entities to use in accounting for revenue. Under the guidance, revenue is recognized when a company transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The standard is effective for public entities with annual and interim reporting periods beginning after December 15, 2017. Entities have the option of using either a full retrospective or a modified retrospective approach to adopt the guidance. We expect to adopt ASU 2014-09 as of January 1, 2018 using the modified retrospective method. We have completed our initial assessment and do not believe there will be a material impact to our condensed consolidated financial statements for the majority of our advertising and subscription revenue arrangements. We are finalizing the impact of ASU 2014-09 and are continuing to evaluate the expected impact on our business processes,
systems and controls. We expect to complete our assessment of the effects of adopting ASU 2014-09 during the fourth quarter of 2017, and we will continue our evaluation of ASU 2014-09, including how it may impact new arrangements we enter into as well as new or emerging interpretations of the standard, through the date of adoption.
In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842) ("ASU 2016-02"). ASU 2016-02 requires lessees to put most leases on their balance sheets and recognize expenses on their income statements and also eliminates the real estate-specific provisions for all entities. The guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We have completed our initial assessment and expect to adopt ASU 2016-02 as of January 1, 2019 using the modified retrospective method. We expect the potential impact of adopting ASU 2016-02 to be material to our lease liabilities and assets on our consolidated balance sheets.
In June 2016, the FASB issued Accounting Standards Update No. 2016-13, Credit Losses—Measurement of Credit Losses on Financial Instruments ("ASU 2016-13"). ASU 2016-13 will replace today’s incurred loss approach with an expected loss model for instruments measured at amortized cost and require entities to record allowances for available-for-sale debt securities rather than reduce the carrying amount. The guidance is effective for fiscal years beginning after December 15, 2019, and interim periods within that fiscal year, although early adoption is permitted. We are currently evaluating the impact that this standard update will have on our condensed consolidated financial statements.
In May 2017, the FASB issued Accounting Standards Update No. 2017-09, Compensation—Stock Compensation (Topic 718), Scope of Modification Accounting ("ASU 2017-09"). ASU 2017-09 clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. The guidance is effective prospectively for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, and early adoption is permitted. We do not expect the adoption of ASU 2017-09 will have a material impact on our financial statements.
Recently Adopted Accounting Standards
In March 2016, the FASB issued Accounting Standards Update No. 2016-09, Compensation—Stock Compensation (Topic 718) ("ASU 2016-09"). ASU 2016-09 requires all income tax effects of awards to be recognized in the income statement when the awards vest or are settled. Additionally, it allows an employer to repurchase more of an employee's shares for tax withholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. We adopted this guidance in the first quarter of 2017 using the modified retrospective transition method. Upon adoption, we recognized the previously unrecognized excess tax benefits as of January 1, 2017 through retained earnings. The previously unrecognized excess tax benefits were recorded as a deferred tax asset, which was fully offset by a valuation allowance. As a result, the net impact resulted in no effect on net deferred tax assets or our accumulated deficit as of January 1, 2017. Without the valuation allowance, the Company’s net deferred tax assets would have increased by approximately $142.0 million. Additionally, we elected to account for forfeitures as they occur, rather than estimating expected forfeitures. The net cumulative effect of this change was an increase to additional paid in capital as of January 1, 2017 of $1.2 million.
