The Company uses valuation techniques that are consistent with the market approach, the income approach, and/or the cost approach to measure assets and liabilities that are measured at fair value. Inputs to valuation techniques refer to the assumptions that market participants would use in pricing the asset or liability. Inputs may be observable, meaning those that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from independent sources, or unobservable, meaning those that reflect the reporting entity's own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. In that regard, accounting standards establish a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:

The Company's MSRs are measured at fair value on a nonrecurring basis. That is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments when there is evidence of impairment. The Company's MSRs do not trade in an active, open market with readily observable prices. While sales of multifamily MSRs do occur on occasion, precise terms and conditions vary with each transaction and are not readily available. Accordingly, the estimated fair value of the Company’s MSRs was developed using discounted cash flow models that calculate the present value of estimated future net servicing income. The model considers contractually specified servicing fees, prepayment assumptions, estimated revenue from escrow accounts, delinquency status, late charges, costs to service, and other economic factors. The Company periodically reassesses and adjusts, when necessary, the underlying inputs and assumptions used in the model to reflect observable market conditions and assumptions that a market participant would consider in valuing an MSR asset. MSRs are carried at the lower of amortized cost or fair value.

A description of the valuation methodologies used for assets and liabilities measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. These valuation methodologies were applied to all of the Company's assets and liabilities carried at fair value:

●

Derivative Instruments—The derivative positions consist of interest rate lock commitments with borrowers and forward sale agreements to the Agencies. The fair value of these instruments is estimated using a discounted cash flow model developed based on changes in the applicable U.S. Treasury rate and other observable market data. The value was determined after considering the potential impact of collateralization, adjusted to reflect nonperformance risk of both the counterparty and the Company, and are classified within Level 3 of the valuation hierarchy.

●

Loans Held for Sale—Loans held for sale are reported at fair value. The Company determines the fair value of the loans held for sale using discounted cash flow models that incorporate quoted observable inputs from market participants. Therefore, the Company classifies these loans held for sale as Level 2.

●

Pledged Securities—Investments in money market funds are valued using quoted market prices from recent trades. Therefore, the Company classifies this portion of pledged securities as Level 1. The Company determines the fair value of its AFS investments in Agency debt securities using discounted cash flows that incorporate observable inputs from market participants and then compares the fair value to broker estimates of fair value. Consequently, the Company classifies this portion of pledged securities as Level 2.

The following table summarizes financial assets and financial liabilities measured at fair value on a recurring basis as of September 30, 2019, and December 31, 2018, segregated by the level of the valuation inputs within the fair value hierarchy used to measure fair value:

The following methods and assumptions were used for recurring fair value measurements as of September 30, 2019.

Cash and Cash Equivalents and Restricted Cash—The carrying amounts approximate fair value because of the short maturity of these instruments (Level 1).

Pledged Securities—Consist of cash, highly liquid investments in money market accounts invested in government securities, and investments in Agency debt securities. The investments of the money market funds typically have maturities of 90 days or less and are valued using quoted market prices from recent trades. The fair value of the Agency debt securities incorporates the contractual cash flows of the security discounted at market-rate, risk-adjusted yields.

Loans Held for Sale—Consist of originated loans that are generally transferred or sold within 60 days from the date that the mortgage loan is funded and are valued using discounted cash flow models that incorporate observable inputs from market participants.

Derivative Instruments—Consist of interest rate lock commitments and forward sale agreements. These instruments are valued using discounted cash flow models developed based on changes in the U.S. Treasury rate and other observable market data. The value is determined after considering the potential impact of collateralization, adjusted to reflect nonperformance risk of both the counterparty and the Company.

Fair Value of Derivative Instruments and Loans Held for Sale—In the normal course of business, the Company enters into contractual commitments to originate and sell multifamily mortgage loans at fixed prices with fixed expiration dates. The commitments become effective

when the borrowers "lock-in" a specified interest rate within time frames established by the Company. All mortgagors are evaluated for creditworthiness prior to the extension of the commitment. Market risk arises if interest rates move between the time of the "lock-in" of rates by the borrower and the sale date of the loan to an investor.

To mitigate the effect of the interest rate risk inherent in providing rate lock commitments to borrowers, the Company's policy is to enter into a sale commitment with the investor simultaneous with the rate lock commitment with the borrower. The sale contract with the investor locks in an interest rate and price for the sale of the loan. The terms of the contract with the investor and the rate lock with the borrower are matched in substantially all respects, with the objective of eliminating interest rate risk to the extent practical. Sale commitments with the investors have an expiration date that is longer than our related commitments to the borrower to allow, among other things, for the closing of the loan and processing of paperwork to deliver the loan into the sale commitment.

Both the rate lock commitments to borrowers and the forward sale contracts to buyers are undesignated derivatives and, accordingly, are marked to fair value through Gains on mortgage banking activities in the Condensed Consolidated Statements of Income. The fair value of the Company's rate lock commitments to borrowers and loans held for sale and the related input levels includes, as applicable:

●

the estimated gain from the expected loan sale to the investor (Level 2);

●

the expected net cash flows associated with servicing the loan, net of any guaranty obligations retained (Level 2);

●

the effects of interest rate movements between the date of the rate lock and the balance sheet date (Level 2); and

●

the nonperformance risk of both the counterparty and the Company (Level 3; derivative instruments only).

The estimated gain considers the origination fees the Company expects to collect upon loan closing (derivative instruments only) and premiums the Company expects to receive upon loan sale (Level 2). The fair value of the expected net cash flows associated with servicing the loan is calculated pursuant to the valuation techniques applicable to MSRs (Level 2).

The fair value of the Company's derivative instruments and loans held for sale considers the effects of the market price movement of the same type of security due to interest rate movements between the trade date and the balance sheet date. To calculate the effects of interest rate movements, the Company uses applicable published U.S. Treasury prices, and multiplies the price movement between the rate lock date or loan origination date and the balance sheet date by the notional amount of the derivative instruments or loans held for sale (Level 2).

The fair value of the Company’s interest rate lock commitments and forward sales contracts is adjusted to reflect the risk that the agreement will not be fulfilled. The Company’s exposure to nonperformance in interest rate lock commitments and forward sale contracts is represented by the contractual amount of those instruments. Given the credit quality of our counterparties and the short duration of interest rate lock commitments and forward sale contracts, the risk of nonperformance by the Company’s counterparties has historically been minimal (Level 3).

The following table presents the components of fair value and other relevant information associated with the Company’s derivative instruments and loans held for sale as of September 30, 2019 and December 31, 2018.
