Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Commitments—In October 2013, we signed a lease for new office space for our corporate headquarters, and moved into the new location in the first quarter of 2014. The lease had a term of 38 months and a rental cost of approximately $5,412 per month, increasing 3% annually after the first fourteen months. In addition, our share of building operating costs were estimated to be $2,101 per month. In April 2014, we amended the lease to add additional space which increased our rent to $8,286 per month beginning August 1, 2014 plus estimated monthly operating costs of $3,154 and extended the lease term through July 2017. We had a renewal option for an additional 3 year term. The original lease included a tenant improvement allowance of $72,160 and the amended lease included an additional tenant improvement allowance of $38,320. The allowances were used to construct our office build-out and have been capitalized as leasehold improvements as of December 31, 2016 and 2017. The capitalized costs are being amortized over the amended lease term through July 2017. Effective April 2017, we amended the lease to add additional space and to extend our lease term through July 2018, with an option to extend through July 2019. With the amendment, the total leased space is now 9,024 square feet with monthly rent of $14,479 through July 31, 2017 and $13,987 from August 1, 2017 through the end of the lease, plus estimated monthly operating costs of approximately $7,000. In May 2018, we entered into an agreement with the landlord to extend the lease for one month, through August 2018 with no change to the amount of rent or other payments due under the lease. We are currently negotiating a lease for a larger office space in the same area, which we expect to complete by the end of May 2018. We expect our rent payments to increase as a result of the new lease. In November 2013, we signed a lease for our satellite development office in Burlingame, CA. The lease had a two-year term, and rental costs of approximately $4,000 per month. In May 2015, we renewed the lease for a one year period expiring November 30, 2016 with rental costs of $5,000 per month. Effective December 16, 2016, we signed a new lease of 5,248 square feet of office space within the same building in Burlingame, California commencing February 2017. The lease has a five year term, and rental costs of approximately $17,000 per month. Rent expense related to our facilities and equipment for the three months ended March 31, 2017 and 2018 was $89,000 and $142,000, respectively. Legal Proceedings—We are occasionally involved in legal proceedings and other matters arising from the normal course of business. On September 24, 2015, a purported shareholder derivative action was filed in the United States District Court for the Central District of California. The plaintiff alleges that certain of our officers and directors breached their fiduciary duties to us, including by allegedly violating the federal securities laws and exposing us to possible financial liability. The parties to the shareholder derivative action have reached a settlement that, if approved by the court, will fully resolve plaintiff’s claims and provide for the release of all claims asserted in the litigation. On February 1, 2018, the court entered an order granting preliminary approval of the settlement. A motion for final approval of the settlement is currently pending. We can make no assurances that the court will grant final approval of the settlement. The settlement amount is not material. We intend to continue to defend ourselves vigorously in these actions. We are not party to any other legal proceedings. We may, from time to time, be party to litigation and subject to claims incident to the ordinary course of business. As our growth continues, we may become party to an increasing number of litigation matters and claims. The outcome of litigation and claims cannot be predicted with certainty, and the resolution of any future matters could materially affect our future financial position, results of operations or cash flows. Legal fees and other costs associated with legal proceedings are expensed as incurred. We assess, in conjunction with our legal counsel, the need to record a liability for litigation and contingencies. Litigation accruals are recorded when and if it is determined that a loss related matter is both probable and reasonably estimable. Material loss contingencies that are reasonably possible of occurrence, if any, are subject to disclosure. We evaluate developments in legal proceedings and other matters on a quarterly basis. As of March 31, 2017 and 2018, there was no litigation or contingency with at least a reasonable possibility of a material loss. No losses have been recorded during the three months ended March 31, 2017 and 2018, respectively, with respect to litigation or loss contingencies.
