The carrying value of the Company’s long-term debt in the above table is presented net of unamortized deferred debt issuance costs. The estimated fair value is determined using the methodologies discussed below in accordance with accounting standards related to the determination of fair value based on the U.S. GAAP fair value hierarchy as discussed in Note 12. The estimated fair value for financial instruments with a fair value that does not equal its carrying value is considered a Level 1 valuation. The Company utilizes the market approach and obtains indicative pricing from the administrative agent to the Credit Facility to determine fair values or through publicly available subscription services such as Bloomberg where relevant.

Cash and cash equivalents. The carrying amount approximates fair value due to the short-term maturity of these instruments (less than three months).

Investments in equity securities. Estimated fair value is based on closing price as quoted in public markets. Prior to the adoption of ASU 2016-01 on January 1, 2018, such investments were classified as either available-for-sale or trading securities.

Available-for-sale securities. Estimated fair value is based on closing price as quoted in public markets or other various valuation techniques.

Trading securities. Estimated fair value is based on closing price as quoted in public markets.

Contingent Value Right. Estimated fair value is based on the closing price as quoted on the public market where the CVR was traded.

Interest rate swaps. The fair value of interest rate swap agreements is the amount at which they could be settled, based on estimates calculated by the Company using a discounted cash flow analysis based on observable market inputs and validated by comparison to estimates obtained from the counterparty. The Company incorporates credit valuation adjustments (“CVAs”) to appropriately reflect both its own nonperformance or credit risk and the respective counterparty’s nonperformance or credit risk in the fair value measurements. In adjusting the fair value of its interest rate swap agreements for the effect of nonperformance or credit risk, the Company has considered the impact of any netting features included in the agreements.
