(3) Assets and Liabilities Measured at Fair Value

For assets and liabilities required to be reported at fair value, GAAP provides a hierarchy that prioritizes inputs to valuation techniques used to measure fair value into three broad levels. Level 1 inputs are quoted market prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2 inputs are inputs, other than quoted market prices included within Level 1, that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability. The Company does not have any recurring assets or liabilities measured at fair value that would be considered Level 3.

The Company’s assets and liabilities measured at fair value are as follows:

​

​

The Company’s exchangeable senior debentures are debt instruments with quoted market value prices that are not considered to be traded on “active markets”, as defined in GAAP, and are reported in the foregoing table as Level 2 fair value.

Other Financial Instruments

Other financial instruments not measured at fair value on a recurring basis include trade receivables, trade payables, accrued and other current liabilities, equity securities, current portion of debt (with the exception of the 1.25% Debentures prior to their redemption in the third quarter of 2023, and the 2.75% Debentures and the 1.75% Debentures prior to their redemption in the first quarter of 2023 (each as defined in note 6)) and long-term debt (with the exception of the 3.125% Debentures (as defined in note 6)). With the exception of long-term debt and preferred stock, the carrying amount approximates fair value due to the short maturity of these instruments as reported on our condensed consolidated balance

sheets. The carrying value of the Margin Loan Facility, the Senior Credit Facility and the Wells Fargo Note Payable (each as defined in note 6) all bear interest at a variable rate and therefore are also considered to approximate fair value.

Realized and Unrealized Gains (Losses) on Financial Instruments

Realized and unrealized gains (losses) on financial instruments are comprised of changes in the fair value of the following:
