Servicing Activities [Abstract]

Schedule of Servicing Assets at Fair Value [Table Text Block]

The following table summarizes past activity related to mortgage servicing rights (MSRs), which were carried at fair value. Management estimated fair value using our transaction data and other market data or, in periods when there were limited MSRs market transactions that were directly observable, internally developed discounted cash flow models (an income approach) were used to estimate the fair value. These internal valuation models estimated net cash flows based on internal operating assumptions that we believed would be used by market participants in orderly transactions combined with market-based assumptions for loan prepayment rates, interest rates, and discount rates that we believed approximate yields required by investors in this asset.
