Derivative Instruments And Hedging Activities Disclosure [Abstract] |
Derivatives Hedges and Financial Instruments | 6. Derivatives, Hedges and Financial Instruments For the periods presented, the following significant instruments are accounted for on a fair value basis: Natural Gas Contracts During the first nine months of 2020, we entered into certain forward natural gas contracts (“natural gas contracts”), which are accounted for on a mark-to-market basis. We are utilizing these natural gas contracts as economic hedges for risk management purposes but are not designated as hedging instruments. At September 30, 2020, our natural gas contracts included 1.0 million MMBtu of natural gas and extend through January 2021 (there were none at December 31, 2019). The valuations of the natural gas contracts are classified as Level 2. At September 30, 2020, the valuation inputs included the contractual weighted-average cost of $2.01 per MMBtu and the weighted-average market value of $2.53 per MMBtu. For the three and nine months ended September 30, 2020, we recognized a $0.5 million gain and a $0.2 million loss (classified as cost of sales), respectively (none for the three and nine months ended September 30, 2019), which includes an unrealized gain of $0.8 million and $0.6 million, respectively, attributed to natural gas contracts still held at the reporting date. Embedded Derivative As discussed in Note 8, certain embedded features (“embedded derivative”) relating to the redemption of the Series E Redeemable Preferred, which includes certain contingent redemption features and the participation rights value have been bifurcated from the Series E Redeemable Preferred and recorded as a liability. At September 30, 2020 and December 31, 2019, we estimate that the contingent redemption features have fair value since we estimate that it is probable that a portion of the shares of this preferred stock would be redeemed prior to October 25, 2023. For certain other embedded features, we estimated no fair value based on our assessment that there is a remote probability that these features will be exercised. The fair value of the embedded derivative was valued using discounted cash flow models and primarily based on the difference in the present value of estimated future cash flows with no redemptions prior to October 25, 2023 compared to certain redemptions deemed probable during the same period and applying the effective dividend rate of the Series E Redeemable Preferred. In addition, at September 30, 2020 and December 31, 2019, the fair value of the embedded derivative included the valuation of the participation rights, which was based on the equivalent of 303,646 shares of our common stock at $1.61 and $4.20 per share, respectively. The valuations of the embedded derivative are classified as Level 3. This derivative is valued using market information, management’s redemption assumptions, the underlying number of shares as defined in the terms of the Series E Redeemable Preferred, and the market price of our common stock. 6. Derivatives, Hedges and Financial Instruments (continued) For the three months ended September 30, 2020 and 2019, we recognized an unrealized gain and unrealized loss of approximately $0.1 million and $0.4 million, respectively, due to the change in fair value of the embedded derivative. For the nine months ended September 30, 2020 and 2019, we recognized an unrealized gain of approximately $0.6 million and $0.1 million, respectively, due to the change in fair value of the embedded derivative. These unrealized gains are included in non-operating other income. The following details our assets and liabilities that are measured at fair value on a recurring basis at September 30, 2020 and December 31, 2019:

Other Financial Instruments At September 30, 2020 and December 31, 2019, we did not have any financial instruments with fair values significantly different from their carrying amounts (which excludes issuance costs, if applicable), except for the Senior Secured Notes as shown below.
