Fair Value Measurements

Financial Assets Measured at Fair Value

ASC Topic 820 establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include the following:

• Level 1, defined as observable inputs such as quoted prices in active markets for identical assets or liabilities;

• Level 2, defined as inputs that are observable either directly or indirectly such as quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active and other inputs that can be corroborated by observable market data; and

• Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

The Company’s fair value hierarchy for its financial assets measured at fair value on a recurring basis as of December 28, 2013 and March 30, 2013 was as follows (in thousands):

For Level 1 assets, the Company utilized quoted prices in active markets for identical assets.

For Level 2 assets, exclusive of forward contracts, the Company utilized quoted prices in active markets for similar assets. For forward contracts, spot prices at December 28, 2013 and March 30, 2013 were utilized to calculate fair values.

During the first three quarters of 2014, there were no transfers between Level 1 and Level 2 assets.
