Basis Of Presentation

1. Basis of Presentation

The accompanying unaudited interim consolidated financial statements have been prepared by NetScout Systems, Inc., or NetScout or the Company. Certain information and footnote disclosures normally included in financial statements prepared under generally accepted accounting principles (GAAP) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). In the opinion of management, the unaudited interim consolidated financial statements include all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of the Company's financial position, results of operations and cash flows. The results reported in these consolidated financial statements are not necessarily indicative of results that may be expected for the entire year. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements, including the notes thereto, included in the Company's Annual Report on Form 10-K for the fiscal year ended March 31, 2011.

Revision of previously reported amounts

During the three-month interim period ended September 30, 2011, the Company identified errors in the presentation of its Condensed Consolidated Statement of Cash Flows for prior fiscal periods. Transfers from inventory to fixed assets were presented as cash outflows within the Purchase of Fixed Assets line and cash inflows within the Inventories line of the Consolidated Statement of Cash Flows. Such items should have been netted down within the Consolidated Statement of Cash Flows and disclosed as a non-cash activity. The Company revised the amounts related to cash provided by operating activities and cash provided by (used in) investing activities in its Consolidated Statement of Cash Flows to correct for these immaterial errors. The Company has detailed the adjustments to prior periods below:

	Year Ended March 31, 2010			Three Months Ended June  30, 2010		Six Months Ended September 30, 2010		Three Months Ended June  30, 2011
Net cash provided by operating activities:
As reported	$	47,224		$	23,854	$	31,932	$	6,319
As adjusted		45,654			23,138		30,584		4,755
Change	$	1,570		$	716	$	1,348	$	1,564
Net cash provided by (used in) investing activities:
As reported	$	(61,075	)	$	13,046	$	22,556	$	(28,994	)
As adjusted		(59,505	)		13,762		23,904		(27,430	)
Change	$	1,570		$	716	$	1,348	$	1,564

The Company has also revised the Consolidated Statement of Cash Flows for the nine month and full year periods in the fiscal year ending March 31, 2011. These revisions changed cash flows from operating activities and cash flows from investing activities by $1.3 million in each period such that: cash flows from operations decreased from $46.0 million to $44.7 million, and cash flows from investing activities increased from $14.0 million to $15.3 million for the nine month period; cash flows from operations decreased from $68.5 million to $67.2 million, and cash out flows from investing activities decreased from $61.3 million to $60.0 million for the full year. The adjustments did not change from the six month period through the remainder of the fiscal year ended March 31, 2011 as later inventory transfers occurred in the same accounting period in which the items were purchased; as such those transactions were properly netted down within operating cash flows and shown gross in investing cash flows. The Company has concluded that the errors described above were immaterial to all periods discussed. These errors had no effect on net income or net income per share.
