 flow analysis to establish fair value. The significant estimates used in fair value methodology, which are based on Level 3 inputs, include the Company's expectations for future operations and projected cash flows, including revenue, gross margin and operating expenses. Reasonably possible changes in those assumptions could result in non-cash impairment charges in the future.

Stock-Based Compensation 

We measure all stock-based awards granted to employees and directors based on the fair value on the date of the grant and recognize the corresponding compensation expense of those awards over the requisite service period, which is generally the vesting period of the respective award. We generally issue stock options, restricted stock units (“RSU’s”) and performance-based market condition share awards ("PSU's") to employees. Stock options and RSUs only have service-based vesting conditions and the Company records the expense for these awards using the straight-line method. PSUs have multiple tranches each with certain market capitalization or stock price milestones and service-based vesting conditions. The Company records the expense for these awards over the estimated life of each tranche

We estimate the fair value of each stock option grant using the Black-Scholes option-pricing model, which uses as inputs the fair value of our common stock and assumptions we make for the volatility of our common stock, the expected term of our stock options, the risk-free interest rate for a period that approximates the expected term of our stock options and our expected dividend yield. The assumptions and estimates are as follows: 

•Fair Value of Class A Common Stock—Following our IPO, we rely on the closing price of our Class A common stock as reported on the date of grant to determine the fair value of our Class A common stock, as shares of our Class A common stock are traded in the public market. 

•Expected Term—The expected term represents the period that the stock-based awards are expected to be outstanding. We determine the expected term using the simplified method. The simplified method deems the term to be the average of the time-to-vesting and the contractual life of the options. For stock options granted to non-employees, the expected term equals the remaining contractual term of the option from the vesting date. 

•Expected Volatility—As we have limited trading history for our common stock, the expected volatility was estimated by taking the average historic price volatility for industry peers, consisting of several public companies in our industry that are either similar in size, stage, or financial leverage, over a period equivalent to the expected term of the awards.
