| (1) |  | Included in cash and cash equivalents.
| (2) |  | Nonqualified deferred compensation plan investments consist of U.S. and international equity mutual funds, government and corporate bond mutual funds, and money market funds which are held in a trust with a third-party brokerage firm. Quoted market prices are used to determine fair values of the investments which are included in other long-term assets, with a corresponding liability reported in other long-term liabilities.
| (3) |  | Fair value measured using quoted prices of identical assets in active markets.
| (4) |  | Included in other long-term liabilities. The interest rate swap fair value was determined by discounting future cash flows and receipts based on expected interest rates observed in market interest rate curves adjusted for estimated credit valuation considerations reflecting nonperformance risk of the Company and the counterparty, which are considered to be in Level 3 of the fair value hierarchy. The Company assessed Level 3 inputs as insignificant to the valuation at June 30, 2016 and December 31, 2015 and considers the interest rate swap valuation in Level 2 of the fair value hierarchy.
