Fair Value Measurements of Assets and Liabilities

The following tables set forth our financial assets and liabilities that were accounted for at fair value on a recurring basis as of January 31, 2013 and January 31, 2012:

The following table sets forth a reconciliation of liabilities measured at fair value on a recurring basis with the use of significant unobservable inputs (Level 3) for the fiscal year ended January 31, 2013 (amounts in thousands):

Available-for-Sale Securities

We rely on mark to market valuations to record the fair value of our available for sale security assets which are measured under a Level 1 input. These assets are publicly-traded equity securities for which market prices are readily observable and recorded. At January 31, 2013 and 2012, we had $6.1 million and $7.9 million, respectively, in short-term marketable securities and $7.2 million and $4.1 million, respectively, in long-term marketable securities.

We determine the appropriate classification of debt securities at the time of purchase and reevaluate such designation as of each balance sheet date. Our investment portfolio consists of money market funds, corporate debt investments, asset-backed securities, government-sponsored enterprises, and state and municipal obligations. All highly liquid investments with an original maturity of three months or less when purchased are considered to be cash equivalents. All cash equivalents are carried at cost, which approximates fair value. Our marketable securities are classified as available-for-sale and are reported at fair value with unrealized gains and losses, net of tax, reported in stockholders’ equity as a component of accumulated other comprehensive income or loss. The amortization of premiums and accretions of discounts to maturity are computed under the effective interest method and is included in interest income. Interest on securities is recorded as earned and is also included in interest income. Any realized gains or losses would be shown in the accompanying consolidated statements of operations and comprehensive income (loss) in other expense, net.

The following is a summary of available-for-sale securities, including the cost basis, aggregate fair value and gross unrealized gains and losses, for cash equivalents, short-and long-term marketable securities portfolio as of January 31, 2013 and 2012:

During fiscal 2013, 2012 and 2011, available-for-sale securities were sold for total proceeds of $0, $0, and $0.5 million, respectively. The gross realized gains and losses for fiscal years 2013, 2012 and 2011 were immaterial. For purposes of determining gross realized gains and losses, the cost of securities sold is based on specific identification.

Contractual maturities of available-for-sale debt securities at January 31, 2013 are as follows (amounts in thousands):

We concluded that there were no other than temporary declines in investments recorded as of January 31, 2013, 2012 and 2011. The unrealized holding losses, net of tax, on available-for-sale securities in the amount of approximately $6,000, $0.1 million and $0.1 million for the years ended January 31, 2013, 2012 and 2011, respectively, have been included in stockholders’ equity as a component of accumulated other comprehensive loss.

Cash, Cash Equivalents and Marketable Securities

Cash and cash equivalents consist primarily of highly liquid investments in money market mutual funds, government sponsored enterprise obligations, treasury bills, commercial paper and other money market securities with remaining maturities at date of purchase of 90 days or less. The fair value of cash (including restricted cash), cash equivalents and marketable securities at January 31, 2013 and 2012 was $120.9 million and $93.8 million, respectively, and approximated fair value.

Restricted Cash

Pursuant to certain lease agreements, share purchase agreements and agreements with financial institutions, we are required to maintain cash reserves, classified as restricted cash. Current restricted cash totaled $0.9 million and $1.2 million at January 31, 2013 and 2012, respectively.

Acquisition-Related Consideration

We determined the fair value of the acquisition-related consideration in connection with the acquisition of eventIS in September 2009 using a probability-weighted discounted cash flow model. This fair value measurement is based on significant inputs not observed in the market and thus represents a Level 3 measurement. Any change in the fair value of the acquisition-related consideration for the deferred fixed purchase price and earn-out payments subsequent to the acquisition date, including changes from events after the acquisition date, such as changes in our estimate of the performance goals, will be recognized in earnings in the period the estimated fair value changes. The fair value of the acquisition-related consideration to be distributed directly to the eventIS, VividLogic and Flashlight selling shareholders is $5.7 million as of January 31, 2013.
