Fair Value Disclosures [Abstract] |
Fair Value of Financial Instruments, Policy [Policy Text Block] | Fair values for agency residential mortgage loans available-for-sale are determined based on quoted market prices for comparable instruments. Fair values for non-agency residential mortgage loans available-for-sale are determined based on purchase commitments from whole loan investors and other relevant market information available to management. Fair values for interest rate lock commitments, including the value of servicing rights, are based on market prices for similar instruments. Forward contracts on mortgage-backed securities are valued based on market prices for similar instruments. Fair values for whole loan investor commitments are based on market prices for similar instruments from the specific whole loan investor. Certain assets are required to be recorded at fair value on a non-recurring basis when events and circumstances indicate that the carrying value may not be recoverable. The non-recurring fair values included in the table above represent only those assets whose carrying values were adjusted to fair value in the current quarter. House and land inventory measured at fair value represents those communities for which we have recorded impairments during the current period. See Note 4 for a more detailed discussion of the valuation methods used for inventory. The carrying amounts of cash and equivalents and Financial Services debt approximate their fair values due to their short-term nature. The fair values of senior notes are based on quoted market prices, when available. If quoted market prices are not available, fair values are based on quoted market prices of similar issues.
