Fair Value, Assets Measured on Recurring Basis

The following table indicates the fair value hierarchy of the valuation techniques the Company utilized to determine such fair values. In general, fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets. The Company considers a security that trades at least weekly to have an active market. Fair values determined by Level 2 inputs utilize data points that are observable, such as quoted prices, interest rates and yield curves. Fair values determined by Level 3 inputs are unobservable data points for the asset, and include situations where there is little, if any, market activity for the asset. The Company’s policy is to recognize transfers between levels as of the actual date of the event or change in circumstances that caused the transfer. The following table presents information about the assets that are measured at fair value on a recurring basis as of March 31, 2013 (in millions).

	March 31, 2013		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
