Fair Value Measurements [Abstract]
Fair Value Measurements	Note 4. Fair Value Measurements The accounting standard for fair value measurements provides a framework for measuring fair value and expands disclosures about fair value measurements. The framework requires the valuation of investments using a three-tiered approach. The statement requires fair value measurement to be classified and disclosed in one of the following categories: Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets and liabilities; Level 2: Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability; or Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e. supported by little or no market activity). As of December 31, 2020 and 2019, we did not have any financial instruments with significant Level 3 inputs and we did not have any financial instruments that are measured at fair value on a recurring basis. As of December 31, 2019, the carrying value of the Company’s 12% Cumulative Exchangeable Redeemable Preferred Stock, par value $.01 per share (the “Public Preferred Stock”) was $139.2 million, and the estimated fair market value was $60.5 million, based on quoted market prices. For certain of our non-derivative financial instruments, including receivables, accounts payable and other accrued liabilities, the carrying amount approximates fair value due to the short-term maturities of these instruments.

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.
