[1] The Statement of Cash Flows for the nine months ended December 31, 2014 reflects immaterial revisions to correct $0.3 million of outstanding payables related to purchases of property and equipment previously included in net cash used for investing activities to net cash used for operating activities and $0.1 million of net realized gains on short-term investments previously classified as net cash used for operating activities to net cash provided by investing activities. As a result, net cash used for operating activities increased by $0.4 million and net cash used for investing activities decreased by the corresponding amount.
