COMMITMENTS AND CONTINGENCIES

NOTE 12 – COMMITMENTS AND CONTINGENCIES

Acquisition related - The Company recorded two contingent liabilities related to the acquisition of Simena, one relates to future consideration to be paid to the former owner which had an initial fair value of $8.0 million at the time of acquisition and another relates to contractual non-compliance liabilities incurred by Simena with an initial fair value of $1.6 million at the time of acquisition. At June 30, 2012, the present value of the future consideration was $7.0 million and the contractual non-compliance liability was $565 thousand.

Legal - From time to time, NetScout is subject to legal proceedings and claims in the ordinary course of business. In the opinion of management, the amount of ultimate expense with respect to any current legal proceedings and claims, if determined adversely, will not have a significant adverse effect on the Company’s financial condition, results of operations or cash flows.

In March 2012, NetScout uncovered and investigated, and in April 2012, disclosed to the U.S. Department of Justice and the California State Attorney General potential violations of federal and California state anti-trust laws. The potential violations involve a former employee and one or more third parties in connection with sales to state governmental agencies during fiscal year 2012. NetScout believes it did not benefit from any of the transactions uncovered and that the amounts involved are not believed to be material. The California State Attorney General is conducting an investigation into the matter. NetScout is cooperating fully and is providing all requested information. In general, the federal and state agencies have the authority to seek fines and other remedies for anti-trust violations; however, no charges or proceedings have been initiated by any governmental agency against NetScout, and the Company has been informed by the Department of Justice that it does not intend to take any action against NetScout. The Company determined that it is probable that there will be amounts due, those amounts are reasonably estimable and have been accrued as an immaterial liability as of June 30, 2012.
