MSA are recorded when loans are sold to investors and the servicing of those loans is retained by the Bank. MSA are subject to interest rate risk and may become impaired when interest rates fall and the borrowers refinance or prepay their mortgage loans. The MSA are derived primarily from single-family loans.

Servicing loans for others generally consists of collecting mortgage payments, maintaining escrow accounts, disbursing payments to investors and processing foreclosures. Income from servicing loans is reported as loan servicing and other fees in the Corporation’s Consolidated Statements of Operations, and the amortization of MSA is reported as a reduction to the loan servicing income. Loan servicing income includes servicing fees from investors and certain fees collected from borrowers, such as late payment fees. As of June 30, 2018 and 2017, the Corporation held borrowers’ escrow balances related to loans serviced for others of $577,000 and $546,000, respectively.

In estimating fair values of the MSA at June 30, 2018 and 2017, the Corporation used a weighted-average constant prepayment rate (“CPR”) of 13.42% and 17.02%, respectively, and a weighted-average discount rate of 9.11% and 9.11%, respectively. Management obtained CPR estimates from an independent third party and reviewed for reasonableness given current market data. The discount rates were derived from market data. The MSA, which is included in prepaid expenses and other assets in the Consolidated Statements of Financial Condition, had a carrying value of $916,000 and a fair value of $1.0 million at June 30, 2018. This compares to the MSA at June 30, 2017 which had a carrying value of $739,000 and a fair value of $811,000. An allowance may be recorded to adjust the carrying value of each category of MSA to the lower of cost or market. As of June 30, 2018, a total allowance of $82,000 was required for six categories of MSA, compared to a total allowance of $158,000 for eight categories of MSA as of June 30, 2017. Total additions to the MSA during the years ended June 30, 2018, 2017 and 2016 were $237,000, $269,000 and $394,000, respectively. Total amortization of the MSA during the years ended June 30, 2018, 2017 and 2016 was $136,000, $167,000 and $243,000, respectively.

Loans sold to the FHLB – San Francisco were completed under the MPF Program, which entitles the Bank to a credit enhancement fee collected from FHLB – San Francisco on a monthly basis and is described in Note 1 under PBM activities.

The following table represents the hypothetical effect on the fair value of the Corporation’s MSA using an unfavorable shock analysis of certain key valuation assumptions as of June 30, 2018 and 2017 . This analysis is presented for hypothetical purposes only. As the amounts indicate, changes in fair value based on changes in assumptions generally cannot be extrapolated because the relationship of the change in assumptions to the change in fair value may not be linear.
