Strategic Investments

The Company has entered into certain equity investments in privately held businesses to achieve certain strategic business objectives. The Company’s investments in equity securities of privately held businesses are accounted for under the cost method. Under the cost method, strategic investments in which the Company holds less than a 20% voting interest and on which the Company does not have the ability to exercise significant influence are carried at the lower of cost or cost reduced by other-than-temporary impairments, as appropriate. These investments are included in other assets on the Company’s condensed consolidated balance sheets. The Company periodically reviews these investments for other-than-temporary declines in fair value based on the specific identification method and writes down investments when an other-than-temporary decline has occurred. During the six months ended September 30, 2012 and 2011, the Company invested $0.5 million and $2.5 million, respectively, in non-marketable equity investments and these amounts were carried at cost.

* At September 30, 2012 and March 31, 2012, approximately $2.0 million and $4.6 million of the estimated fair value presented were mortgage-backed securities, respectively.

The established guidelines for measuring fair value and expanded disclosures regarding fair value measurements are defined as a three-level valuation hierarchy for disclosure of fair value measurements as follows:

Level 1 —	Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date.
Level 2 —	Inputs (other than quoted market prices included in Level 1) are either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life.
Level 3 —	Inputs reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model. Valuation of instruments includes unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of assets or liabilities.

The following is a summary of cash, cash equivalents and available-for-sale investments by type of instruments measured at fair value on a recurring basis (in thousands):

	September 30, 2012								March 31, 2012

There were no significant transfers in and out of Level 1 and Level 2 fair value measurements during the three and six months ended September 30, 2012.

The Company periodically reviews its strategic investments for other-than-temporary declines in fair value based on the specific identification method and writes down investments when an other-than-temporary decline has occurred. No other-than-temporary declines were recorded during the three months ended September 30, 2012. During the three and six months ended September 30, 2012, the Company invested zero and $0.5 million in a non-marketable equity investment and this amount was carried at cost.

The following is a summary of the cost and estimated fair values of available-for-sale securities with stated maturities, which include U.S. Treasury securities and agency bonds, corporate bonds and mortgage-backed and asset-backed securities, by contractual maturity (in thousands):

Other-Than-Temporary Impairment

Based on an evaluation of securities that have been in a loss position, the Company did not recognize any other-than-temporary impairment charges, for the three and six months ended September 30, 2012 and 2011. The Company considered various factors which included a credit and liquidity assessment of the underlying securities and the Company’s intent and ability to hold the underlying securities until its estimated recovery of amortized cost. As of September 30, 2012 and March 31, 2012, the Company also had $8.3 million and $7.5 million in gross unrealized gains, respectively. The basis for computing realized gains or losses is by specific identification.

Warranty reserves

The Company’s products typically carry a one year warranty. The Company establishes reserves for estimated product warranty costs at the time revenue is recognized. Although the Company engages in extensive product quality programs and processes, its warranty obligation is affected by product failure rates, use of materials and service delivery costs incurred in correcting any product failure. Should actual product failure rates, use of materials or service delivery costs differ from the Company’s estimates, additional warranty reserves could be required, which could reduce its gross margin.

The following table summarizes warranty reserve activity (in thousands):

Net loss per share:

Shares used in basic net loss per share are computed using the weighted average number of common shares outstanding during each period. Shares used in diluted net loss per share include the dilutive effect of common shares potentially issuable upon the exercise of stock options, vesting of restricted stock units (“RSUs”) and outstanding warrants. However, potentially issuable common shares are not used in computing diluted net loss per share as their effect would be anti-dilutive due to the loss recorded during the periods presented. The reconciliation of shares used to calculate basic and diluted net loss per share consists of the following (in thousands, except per share data):

	Three Months Ended September 30,						Six Months Ended September 30,
	2012			2011			2012			2011
Net loss	$	(21,557	)	$	(1,152	)	$	(44,947	)	$	(8,029	)
Shares used in net loss per share computation:
Weighted average common shares outstanding, basic		64,947			62,526			63,678			63,202
Net effect of dilutive common share equivalents		—			—			—			—
Weighted average common shares outstanding, diluted		64,947			62,526			63,678			63,202
Basic and diluted net loss per share	$	(0.33	)	$	(0.02	)	$	(0.71	)	$	(0.13	)

The effect of anti-dilutive securities (comprised of options and restricted stock units) totaling 10.2 million and 10.3 million equivalent shares for the three and six months ended September 30, 2012, respectively, and 9.9 million and 7.8 million shares for the three and six months ended September 2011, respectively, have been excluded from the net loss per share computation, as their impact would be anti-dilutive because the Company has incurred losses in the periods presented.

The effect of dilutive securities (comprised of options and restricted stock units) totaling 0.5 million and 0.4 million equivalent shares for the three and six months ended September 30, 2012, respectively, and 0.1 million and 0.6 million shares for the three and six months ended September 2011, respectively, have been excluded from the net loss per share computation, as their impact would be anti-dilutive because the Company has incurred losses in the periods presented.

Total equivalent shares excluded from the net loss per share computation are 10.7 million each for the three and six months ended September 30, 2012, respectively, and 10.0 million and 8.4 million shares for three and six months ended September 30, 2011, respectively.
