[1] The Statement of Cash Flows for the six months ended September 30, 2014 reflects an immaterial revision to correct 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. As a result, net cash used for operating activities increased by $0.3 million and net cash used for investing activities decreased by the corresponding amount.

[2] The Condensed Consolidated Balance Sheet as of March 31, 2015 has been derived from the audited Consolidated Financial Statements at that date but does not include all disclosures required by generally accepted accounting principles for complete financial statements.
