Warrants	WARRANTS Warrants to Purchase Common Stock In addition to the warrants issued during 2013 as discussed in Note 9, the Company has issued warrants to purchase the Company’s common stock in connection with debt arrangements, a distributor agreement and the purchase of certain domain names. All warrants were fully vested, non-forfeitable and immediately exercisable upon issuance and are equity classified. At December 31, 2013, no additional warrants to purchase common stock, other than as discussed in Note 9, were outstanding. During 2012, warrants to purchase 130,000 shares of common stock were exercised at an exercise price of $1.60 per share. During 2011, 898,447 shares of common stock, including 133,000 shares issued upon exercise of warrants that were granted to ADP in 2011 as discussed below, were issued upon the exercise of common stock warrants at a weighted-average exercise price of $0.95 per share. On May 6, 2009, the Company entered into a five-year global distributor agreement with ADP that provides ADP the right to distribute the Company’s core solution to its customers under ADP’s name. In connection with the distributor agreement, the Company also entered into a warrant agreement to provide additional incentives to ADP. The warrant agreement provided that ADP was eligible to earn fully vested and immediately exercisable ten-year warrants to purchase between zero and 886,096 shares of the Company’s common stock at an exercise price of $0.53 per share if ADP met specified sales targets for each contract year until the earlier of the completion of the five-year term of the distributor agreement or the completion of an initial public offering of the Company’s common stock. When ADP achieved the defined sales targets and earned a warrant for a contract year, the Company recorded the fair value of such warrant as a reduction of revenue. The Company determined the fair value of these warrants using a Black-Scholes option-pricing model, which incorporated several estimates and assumptions that were subject to significant judgment. On November 24, 2010, the Company amended its warrant agreement with ADP to modify certain definitions related to future sales targets, to acknowledge that no warrants would be issued for the contract year ended June 30, 2010 and to remove the anti-dilution provisions in the warrant agreement. In connection with the amendment, the Company issued ADP a fully vested and non-forfeitable warrant to purchase 360,000 shares of its common stock at an exercise price of $0.01 per share, which was valued at approximately $2.9 million as of the amendment date using the Black-Scholes option pricing model. This amount was recorded as a reduction of revenue in the fourth quarter of 2010 as the agreement provides ADP with the right to be distributor of the Company’s services and the Company estimates that ADP will purchase additional services from the Company. In issuing this warrant, the Company considered the strategic importance of its ongoing relationship with ADP and the expected timing of the completion of its IPO, after which ADP would no longer be eligible to earn any warrants. At December 31, 2010, the Company did not record any reduction in revenue for the contract year ended June 30, 2011, as the minimum specified sales target had not been achieved to earn the applicable warrant as of December 31, 2010. Upon the completion of the Company’s IPO, ADP was no longer eligible to earn warrants under the warrant agreement. However, ADP remained eligible to earn a warrant for the partial contract year that began on July 1, 2010 and ended on March 22, 2011, the closing date of the Company’s IPO, if it met pro-rated specified sales targets for that period. For the three months ended March 31, 2011, no reductions of revenue were recorded because the Company concluded that ADP had not met the pro-rated specified sales targets for such partial contract year based on the Company’s assessment of the contractual terms of the arrangement, and as of March 31, 2011, it was not considered probable that the Company would be required to issue a warrant for such partial contract year. Pursuant to the terms of the arrangement, the Company notified ADP that it had not earned the warrant for such partial year. ADP contended that it had met the pro-rated specified sales target for the partial contract year that would entitle ADP to a warrant to purchase 443,048 shares of the Company’s common stock at an exercise price of $0.53 per share. During June 2011, in order to resolve a dispute with respect to this matter, the Company issued ADP a fully vested and non-forfeitable warrant to purchase 133,000 shares of the Company’s common stock at an exercise price of $0.53 per share. The warrant was valued at approximately $2.5 million using a Black-Scholes option-pricing model as of the issuance date and was recorded as a non-cash reduction of revenue in the second quarter of 2011. In connection with the Company’s issuance of the warrant described above, ADP agreed and acknowledged that it is no longer eligible to earn or receive any additional warrants exercisable for shares of the Company’s common stock pursuant to the distributor agreement.
