Table of Contents Consolidation and Variable Interest Entities We are required to consolidate entities deemed to be VIEs in which we are the primary beneficiary. We are considered to be the primary beneficiary of a VIE when we have (i) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and (ii) the obligation to absorb losses or receive benefits that could potentially be significant to the VIE. Asset Retirement Obligations Certain lease agreements contain provisions that require us to remove leasehold improvements at the end of the lease term. When such an obligation exists, we record an asset retirement obligation at the inception of the lease at its estimated fair value. The associated asset retirement costs are capitalized as part of the carrying amount of the leasehold improvements and depreciated over their useful lives. The asset retirement obligation is accreted to its estimated future value as interest expense using the effective-interest rate method. Revenue Recognition We recognize revenue under the five-step model required under ASC 606, which requires us to identify the relevant contract with the member, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations identified and recognize revenue when (or as) each performance obligation is satisfied. We maintain an allowance for doubtful accounts for estimated losses resulting from the inability of our members to make required payments. If the financial condition of a specific member were to deteriorate, resulting in an impairment of its ability to make payments, additional allowances may be required. Stock-based Compensation Stock-based compensation expense attributable to equity awards granted to employees is measured at the grant date based on the fair value of the award. The expense is recognized on a straight-line basis over the requisite service period for awards that vest, which is generally the period from the grant date to the end of the vesting period. Stock-based awards provided to non-employees are measured and expensed as the services are provided. Unvested stock-based awards provided to non-employees are remeasured each reporting period. We expect to continue to grant stock-based awards in the future, and, to the extent that we do, our stock-based compensation expense recognized in future periods will likely continue to represent a significant expense. We estimate the fair value of stock option awards granted using the Black-Scholes-Merton option pricing formula (the “Black-Scholes Model”) and a single option award approach. This model requires various significant judgmental assumptions in order to derive a final fair value determination for each type of award, including the expected term, expected volatility, expected dividend yield, risk-free interest rate, and fair value of our stock on the date of grant. The expected option term for options granted is calculated using the “simplified method.” This election was made based on the lack of sufficient historical exercise data to provide a reasonable basis upon which to estimate the expected term. The simplified method defines the expected term as the average of the contractual term and the vesting period. Estimated volatility is based on similar entities whose stock is publicly traded. We use the historical volatilities of similar entities due to the lack of sufficient historical data for our common stock price. Dividend yields are based on our history and expected future actions. The risk-free interest rate is based on the yield curve of a zero coupon U.S. Treasury bond on the date the stock option award was granted with a maturity equal to the expected term of the stock option award. All grants of stock options have an exercise price equal to or greater than the fair market value of our common stock on the date of grant. Because there has historically been no public market for our stock, the fair value of our equity has historically been approved by our board of directors or the compensation committee thereof at the time stock-based awards were granted. In estimating the fair value of stock, we use the assistance of a third- party valuation specialist and considered factors we believe are material to the valuation process, including but not limited to, the price at which recent equity was issued by us or transacted between third parties, actual and projected financial results, risks, prospects, economic and market conditions, the time frame for a potential public offering and estimates of weighted average cost of capital. We believe the combination of these factors provides an appropriate estimate of our expected fair value and reflects the best estimate of the fair value of our common stock at each grant date. 125
