Fair Value Disclosures [Abstract]
FAIR VALUE OF FINANCIAL INVESTMENTS	FAIR VALUE OF FINANCIAL INSTRUMENTS 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 are 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 statements of operations, as described in Note N. The fair value of the liability was estimated to be $28 million and $24 million as of March 31, 2022 and December 31, 2021, 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 March 31, 2022 was approximately $3.1 billion, compared with the aggregate carrying value of $3.2 billion. The aggregate estimated market value of our short-term and long-term debt at December 31, 2021 was approximately $3.2 billion, compared with the aggregate carrying value of $3.0 billion.
