In January 2015, we completed the acquisition of AccountNow, Inc. We issued approximately 514,000 shares of our Class A common stock on the date of close and the remainder of the consideration was paid in cash. AccountNow's results of operations are included in our consolidated statements of operations following the acquisition date. We have not presented pro-forma results of operations because the effect of this acquisition was not material to our financial results. Of the total consideration transferred, we made a preliminary allocation of $61.6 million and $16.1 million to goodwill and intangible assets, respectively. We may adjust this allocation after obtaining more information regarding, among other things, asset valuations, liabilities assumed, and revisions to preliminary estimates over the measurement period not to exceed 12 months from the date of acquisition.
