Amendment Description	This Amendment No. 1 is being filed to restate our unaudited condensed consolidated financial statements as of March 31, 2012 to correct the recording of commission payments from our mid-market product-line. Under our accounting policies in effect at the time of the filing of the original Quarterly Report, we recognized revenue from up-front commissions as cash was received from the energy supplier, beginning with the quarter ended December 31, 2011. However, in connection with the preparation of our Annual Report on Form 10-K for the year ended December 31, 2012, we determined that we were required to record these revenues upon contract completion, or earlier to the extent that actual energy usage data is received from the energy supplier or can be reliably estimated. As we did not receive actual energy usage from the energy supplier as the upfront payments were made and we have not been able to retrospectively obtain actual energy usage to make a reliable estimate of these amounts, we have deferred revenue recognition until evidence is obtained that actual energy has occurred or until the end of contract term. We expect to recognize these amounts of revenue and net income in subsequent periods.Generally, for the three months ended March 31, 2012, this change in accounting treatment and financial statement restatements has resulted in: • No impact to our cash, cash equivalents, short-term investments or overall cash flow; • A decrease in our revenue of $1.1 million (14.3%), a net loss of $0.8 million from net income of $0.3 million and a net loss per share of $(0.07) compared to net income per share of $0.03 for the three months ended; and • A decrease in current assets of $0.5 million (5.8%), an increase in total assets of $0.2 million (0.7%), an increase incurrent liabilities of $0.3 million (3.7%), an increase in total liabilities of $1.9 million (15.5%) and a decrease in shareholders’ equity of $1.7 million (7.8%).
