Accounting Standards Update and Change in Accounting Principle [Abstract]
Recent Accounting Pronouncements	3. Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) ("ASC 842"). The update establishes principles for recognition, measurement, presentation, and disclosure intended to increase transparency and comparability for the accounting of lease transactions. The standard required lessees to recognize leases with terms greater than 12 months on the balance sheet and disclose key information about leasing arrangements. ASC 842 was effective for the Company for fiscal years beginning after December 15, 2021. The Company adopted the new standard as of January 1, 2022, using the required modified retrospective approach. Comparative periods were not adjusted and continue to be presented under the previous accounting guidance. The Company elected the package of practical expedients permitted under the ASC 842 transition guidance, which among other things, allowed it to carry forward the historical lease classification. The impact of adoption was the recognition of right-of-use assets and lease liabilities of $1.9 million for real estate operating leases at January 1, 2022. In addition, ASC 842 required new disclosures for lease transactions. Refer to Note 9, "Operating Leases," for new lease disclosures. In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses. This guidance required financial instruments to be measured at amortized cost, and trade accounts receivable to be presented at the net amount expected to be collected. The new model requires an entity to estimate credit losses based on historical information, current information, and reasonable and supportable forecasts, including estimates of prepayments. In November 2019, the FASB issued ASU 2019-10, that was effective for fiscal years beginning after December 15, 2022, and interim periods within that fiscal year. The Company adopted the standard on January 1, 2023. The adoption of this guidance did not have a material impact on the Company's financial statements. Recent Accounting Pronouncements Not Yet Adopted In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280) ("ASC 280"). The update requires all public business entities to identify their reportable segments, including the basis of organization, types of products and services from which each reportable segment derives its revenues, and the title and position of the individual or the name of the group or committee identified as the chief operating decision maker ("CODM") and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. Public entities shall disclose on an annual and interim basis for each reportable segment including entities that only have one reportable segment, certain significant expense categories and amounts that are regularly provided to the CODM and included in reported segment profit or loss. ASC 280 is applied retrospectively to all prior periods presented in the financial statements. This new guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The Company is currently evaluating the impact of the new standard on its financial statements and related disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740) ("ASC 740"). The update requires all public business entities on an annual basis to (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold and an explanation, if not otherwise evident, of the individual reconciling items disclosed, such as the nature, effect, and underlying causes of the reconciling items and the judgment used in categorizing the reconciling items. In addition, the update requires certain new disclosures of the amount of income taxes paid (net of refunds received) disaggregated by federal, state, and foreign taxes and the amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions in which income taxes paid is equal to or greater than five percent of total income taxes paid (net of refunds received). Other new disclosures required include income (or loss) from continuing operations before income tax expense (or benefit) disaggregated between domestic and foreign and income tax expense (or benefit) from continuing operations disaggregated by federal, state, and foreign. The new guidance is effective for annual periods beginning after December 15, 2024. Early adoption is permitted. The amendments are to be applied on a prospective basis, with retrospective application permitted. The Company is currently evaluating the impact of the new standard on its financial statements and related disclosures.
