Recent Accounting Pronouncements [Abstract]
Recent Accounting Pronouncements	In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The new accounting rules reduce complexity by removing specific exceptions to general principles related to intraperiod tax allocations, ownership changes in foreign investments, and interim period income tax accounting for year-to-date losses that exceed anticipated losses. The new accounting rules also simplify accounting for franchise taxes that are partially based on income, transactions with a government that result in a step up in the tax basis of goodwill, separate financial statements of legal entities that are not subject to tax, and enacted changes in tax laws in interim periods. The new accounting rules will be effective for the Company in the first quarter of 2021. The Company is currently in the process of evaluating the impact of adoption of the new accounting rules on the Company’s financial position, results of operations, cash flows and disclosures.
