Fair Value Measurements

3. Fair Value Measurements

The Company applies fair value accounting for all assets and liabilities that are recognized or disclosed at fair value in its consolidated financial statements on a recurring basis. Fair value represents the amount that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities, the Company considers the principal or most advantageous market and the market-based risk measurements or assumptions that market participants would use in pricing the asset or liability.

The fair values of cash equivalents, trade accounts receivable, settlement assets and obligations, and accounts payable approximate their respective carrying values due to the short period of time to maturity. The estimated fair value of total debt was $4.3 billion at June 30, 2015 and $3.9 billion at December 31, 2014 and was estimated using quoted prices in inactive markets (level 2 of the fair value hierarchy) or using discounted cash flows based on the Company’s current incremental borrowing rates (level 3 of the fair value hierarchy).
