The Company has evaluated the investment securities in the above tables and has determined that the decline in their value is temporary. The unrealized losses are primarily due to changes in market interest rates and spreads in the market for mortgage-related products. The fair value of these securities is expected to recover as the securities approach their maturity dates and/or as the pricing spreads narrow on mortgage-related securities. The Company has the ability and the intent to hold the investments until the market value recovers. Furthermore, as of March 31, 2019, management does not have the intent to sell any of the securities classified as available for sale where the estimated fair value is below the recorded value and believes that it is more likely than not that the Company will not have to sell such securities before a recovery of cost (or recorded value if previously written down).

The Company bifurcates OTTI into (1) amounts related to credit losses which are recognized through earnings and (2) amounts related to all other factors which are recognized as a component of other comprehensive income (loss). To determine the component of the gross OTTI related to credit losses, the Company compared the amortized cost basis of the OTTI security to the present value of its revised expected cash flows, discounted using its pre-impairment yield. The revised expected cash flow estimates for individual securities are based primarily on an analysis of default rates, prepayment speeds and third-party analytic reports. Significant judgment by management is required in this analysis that includes, but is not limited to, assumptions regarding the collectability of principal and interest, net of related expenses, on the underlying loans.

The following table presents a summary of the significant inputs utilized to measure management’s estimates of the credit loss component on OTTI securities as of March 31, 2019 and 2018:



	Range				Weighted
	Minimum		Maximum		Average
March 31, 2019
Constant prepayment rate	6.00	%	15.00	%	10.24	%
Collateral default rate	—	%	16.06	%	5.20	%
Loss severity rate	—	%	78.00	%	40.02	%

March 31, 2018
Constant prepayment rate	6.00	%	15.00	%	11.01	%
Collateral default rate	—	%	11.85	%	5.04	%
Loss severity rate	—	%	72.00	%	38.32	%
