Fair Value Disclosures [Abstract]
Fair Value Of Financial Investments	FAIR VALUE OF FINANCIAL INVESTMENTS Preferred Stock of ACProducts Holding, Inc. As described in Note C, in conjunction with our divestiture of Cabinetry, we received preferred stock of ACProducts Holding, Inc., the holding company of the buyer, with a liquidation preference of $150 million. We did not have the ability to exercise significant influence, and the fair value of this security was not readily available. We elected to measure this investment at cost (less impairment, if any) adjusted for observable price changes in orderly transactions for identical or similar investments of the same issuer for subsequent measurements of fair value. As the preferred stock was received in conjunction with the sale of Cabinetry, we determined the cost to be the fair value of the preferred stock at the time of sale, which was determined to be $136 million and was included in other assets in our condensed consolidated balance sheet. In May 2021, we received, in cash, $166 million for the redemption of the preferred stock, including all accrued but unpaid dividends, and recognized a gain of $14 million which was included within other, net in our condensed consolidated statements of operations. Prior to the redemption, dividends earned on this investment were included within other, net in our condensed consolidated statements of operations with a corresponding increase to our basis in the investment. We had dividend income of $6 million for the nine months ended September 30, 2021, and $3 million and $7 million for the three and nine months ended September 30, 2020, respectively. The preferred stock was reported at the carrying value of $146 million in other assets in our condensed consolidated balance sheet at December 31, 2020. Kraus Acquisition Contingent Consideration. As described in Note B, we may be obligated to pay up to an additional $50 million in 2023 for the Kraus acquisition contingent upon the achievement of certain financial performance metrics for the year ending December 31, 2022. The measurement of the liability for contingent consideration is based on significant inputs that are not observable in the market, and is therefore classified as Level 3 inputs. Examples of utilized unobservable inputs are estimated future revenues and earnings of the acquired business and an applicable discount rate. The estimate of the liability may fluctuate if there are changes in the forecast of the acquired business' future revenues and earnings, as a result of actual levels achieved, or in the discount rate used to determine the present value of contingent future cash flows. All subsequent remeasurements from the initial estimate at the time of acquisition are recorded in other, net in our condensed consolidated statement of operations, as described in Note N. The fair value of the liability was estimated to be $22 million and $8 million as of September 30, 2021 and December 31, 2020, respectively, using probability weighted discounted cash flows and a discount rate that reflects the uncertainty surrounding the expected outcomes, which we believe is appropriate and representative of a market participant assumption. Fair Value of Debt. The fair value of our short-term and long-term fixed-rate debt instruments is based principally upon modeled market prices for the same or similar issues, which are Level 1 inputs. The aggregate estimated market value of our short-term and long-term debt at September 30, 2021 was approximately $3.2 billion, compared with the aggregate carrying value of $3.0 billion. The aggregate estimated market value of our short-term and long-term debt at December 31, 2020 was approximately $3.3 billion, compared with the aggregate carrying value of $2.8 billion.
