Accounting Policies [Abstract]
New Accounting Pronouncement or Change in Accounting Principle, Description	In April 2020, the Financial Accounting Standards Board (FASB) issued a question-and-answer document (the “Lease Modification Q&A”) focused on the application of lease accounting guidance to lease concessions provided as a result of COVID-19. Under existing lease guidance, the Company would have to determine, on a lease by lease basis, if a lease concession was the result of a new arrangement reached with the tenant or if a lease concession was under the enforceable rights and obligations within the existing lease agreement. The Lease Modification Q&A clarifies that entities may elect to not evaluate whether lease-related relief that lessors provide to mitigate the economic effects of COVID-19 on lessees is a lease modification under current lease guidance. Instead, an entity that elects not to evaluate whether a concession directly related to COVID-19 is a modification can then elect whether to apply the modification guidance. Other accounting standards that have been issued or proposed by the FASB are currently not applicable to the Company or are not expected to have a significant impact on the Company's financial position, results of operations, and cash flows.
