Fair Value Disclosures [Abstract]
Fair Value Measurement and Disclosures	See Note 19, Fair Value Measurements and the Fair Value of Financial Instruments caption in Note 1, Summary of Significant Accounting Policies in our 2020 Form 10-K for more information on the input levels and methodologies we use in determining fair value.
Fair Value Transfers	The Company's policy regarding the recording of transfers between levels is to record any such transfers at the end of the reporting period.
Impairment or Disposal of Long-Lived Assets	The Company records impairment losses on long-lived assets held for sale when the fair value of such long-lived assets is below their carrying values. The Company records impairment charges on long-lived assets used in operations when events and circumstances indicate that long-lived assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than their carrying amounts. No impairment charges were recorded during the three months ended June 27, 2020.
Transfers and Servicing of Financial Assets	Mortgage Servicing. Mortgage Servicing Rights ("MSRs") are the rights to receive a portion of the interest coupon and fees collected from the mortgagors for performing specified mortgage servicing activities, which consist of collecting loan payments, remitting principal and interest payments to investors, managing escrow accounts, performing loss mitigation activities on behalf of investors and otherwise administering the loan servicing portfolio. MSRs are initially recorded at fair value. Changes in fair value subsequent to the initial capitalization are recorded in the Company's results of operations. The Company recognizes MSRs on all loans sold to investors that meet the requirements for sale accounting and for which servicing rights are retained.The Company applies fair value accounting to MSRs, with all changes in fair value recorded to Net revenue in accordance with ASC 860-50, Servicing Assets and Liabilities. The fair value of MSRs is based on the present value of the expected future cash flows related to servicing these loans. The revenue components of the cash flows are servicing fees, interest earned on custodial accounts and other ancillary income. The expense components include operating costs related to servicing the loans (including delinquency and foreclosure costs) and interest expenses on servicer advances that are consistent with the assumptions major market participants use in valuing MSRs. The expected cash flows are primarily impacted by prepayment estimates, delinquencies and market discounts. Generally, the value of MSRs is expected to increase when interest rates rise and decrease when interest rates decline, due to the effect those changes in interest rates have on prepayment estimates.
