Note 5. Fair Value Measures

ASC 820-10, Fair Value Measurements and Disclosures, defines fair value, establishes guidelines and enhances disclosure requirements for fair value measurements. The accounting guidance requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The accounting guidance also establishes a fair value hierarchy based on the independence of the source and objective evidence of the inputs used. There are three fair value hierarchies based upon the level of inputs that are significant to fair value measurement:

Level 1—Observable inputs that reflect quoted prices (unadjusted) for identical instruments in active markets;

Level 2—Observable inputs other than quoted prices included in Level 1 for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-driven valuations in which all significant inputs and significant value drivers are observable in active markets; and

Level 3—Unobservable inputs to the valuation derived from fair valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

On a recurring basis, the Company measures the fair value of certain of its assets and liabilities, which include cash equivalents, short-term investments, non-qualified deferred compensation plan assets, foreign currency derivative contracts and contingent consideration associated with business combinations.

The Company’s cash equivalents are classified within Level 1 or Level 2 because they are valued using quoted market prices in an active market or alternative independent pricing sources and models utilizing market observable inputs.

The Company’s non-qualified deferred compensation plan assets consist of money market and mutual funds invested in domestic and international marketable securities that are directly observable in active markets and are therefore classified within Level 1.

The Company’s foreign currency derivative contracts are classified within Level 2 because these contracts are not actively traded and the valuation inputs are based on quoted prices and market observable data of similar instruments.

The Company’s borrowings under its credit and term loan facilities are classified within Level 2 because these borrowings are not actively traded and have a variable interest rate structure based upon market rates currently available to the Company for debt with similar terms and maturities. Refer to Note 8. Credit Facility.

The Company’s liabilities for contingent consideration are classified within Level 3 because these valuations are based on management assumptions including discount rates and estimated probabilities of achievement of certain milestones which are unobservable in the market. The Company did not record any changes during the three and nine months ended July 31, 2013 and the three months ended July 31, 2012. For the nine months ended July 31, 2012, the Company recorded a reduction of $3.0 million in research and development expenses due to the change in fair value of the liability for contingent consideration. As of July 31, 2013 and October 31, 2012, the fair value of the liabilities for contingent consideration was estimated at $0.4 million and $0.8 million, respectively.

Equity investments in privately-held companies, also called non-marketable equity securities are accounted for using either the cost or equity method of accounting.

These equity investments are classified within Level 3 as they are valued using significant unobservable inputs or data in an inactive market, and the valuation requires management judgment due to the absence of market price and inherent lack of liquidity. The non-marketable equity securities are measured and recorded at fair value when an event or circumstance which impacts the fair value of these securities indicates an other-than-temporary decline in value has occurred. The Company monitors these investments and generally uses the income approach to assess impairments based primarily on the financial conditions of these companies.

The following non-marketable equity securities were measured and recorded at fair value within other long-term assets on a non-recurring basis. The losses on these securities were recorded in other income (expense), net.

As of October 31, 2012, the fair value of non-marketable securities was $11.7 million, of which $7.0 million and $4.7 million were accounted for under the cost method and equity method, respectively.
