Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis of Financial Statement Presentation | Basis of Financial Statement Presentation The accompanying unaudited condensed consolidated financial statements and notes to the unaudited condensed consolidated financial statements are presented in accordance with the rules and regulations of the Securities and Exchange Commission and do not include all the disclosures normally required in annual consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"). The unaudited condensed consolidated financial statements, in the opinion of management, contain all normal recurring adjustments necessary to present a fair statement of the condensed consolidated balance sheets as of March 31, 2023, the statements of income and shareholders’ equity for the three months ended March 31, 2023 and 2022, and the statements of cash flows for the three months ended March 31, 2023 and 2022. The December 31, 2022 condensed consolidated balance sheet was derived from the audited financial statements. These interim unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto in the Company's Annual Report on Form 10-K for the year ended December 31, 2022 (the "Annual Report"). The financial results for the interim periods may not be indicative of the financial results for the entire year as our future assessment of our current expectations could result in material impacts to our consolidated financial statements in future reporting periods.
Use of Estimates | Use of Estimates The preparation of the Company's financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates that affect the reported amounts of assets, liabilities, sales and expenses, and related disclosures of contingent assets and liabilities. Significant items subject to such estimates and assumptions include the carrying value of property, plant and equipment; intangible assets; the fair value of assets or liabilities acquired in a business combination; valuation allowances for receivables, inventories and deferred income tax assets and liabilities; environmental liabilities; liabilities for potential tax deficiencies; and, potential litigation claims and settlements. The Company bases these estimates on historical results and various other assumptions believed to be reasonable, all of which form the basis for making estimates concerning the carrying value of assets and liabilities that are readily available from other sources. Actual results may differ from these estimates. Reclassifications Certain prior period amounts have been reclassified to conform to current period presentation, including the reclassification of immaterial revenue and expenses related to the Palmer business within the Company's reportable segments.
Accounting Pronouncements Not Yet Adopted | Accounting Pronouncements Recently AdoptedOn March 31, 2023, the Company adopted ASU 2020-04 "Reference Rate Reform (Topic 848): Facilitation of Effects of Reference Rate Reform on Financial Reporting." The ASU, and subsequent clarifications, provide practical expedients for contract modification accounting related to the transition away from the London Interbank Offered Rate (LIBOR) and other interbank offering rates to alternative reference rates. The expedients are applicable to contract modifications made and hedging relationships entered into on or before December 31, 2024. The Company intends to use the expedients where needed for reference rate transition. The adoption of this standard by the Company did not have a material effect on the condensed consolidated financial statements or footnote disclosures
Fair Value of Financial Instruments | Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. To measure fair value, we use a three-tier valuation hierarchy based upon observable and non-observable inputs: Level 1 - Unadjusted quoted prices that are available in active markets for identical assets or liabilities at the measurement date. Level 2 - Significant other observable inputs available at the measurement date, other than quoted prices included in Level 1, either directly or indirectly, including: •Quoted prices for similar assets or liabilities in active markets; •Quoted prices for identical or similar assets or liabilities in non-active markets; •Inputs other than quoted prices that are observable for the asset or liability; and •Inputs that are derived principally from or corroborated by other observable market data. Level 3 - Significant unobservable inputs that cannot be corroborated by observable market data and reflect the use of significant management judgment. These values are generally determined using model-based techniques, including option pricing models, discounted cash flow models, probability weighted models, and Monte Carlo simulations.
