The Company reviews its investment portfolio quarterly for indications of other-than-temporary impairment (“OTTI”). The initial indicator of OTTI for both debt and equity securities is a decline in fair value below book value and the severity and duration of the decline. For debt securities, the credit-related OTTI is recognized as a charge to noninterest income and the noncredit-related OTTI is recognized in other comprehensive income (“OCI”). During the
three
months ended
March
31,
2017
and
2016,
the Company incurred
no
OTTI charges on debt securities. Temporary impairment on debt securities is primarily related to changes in benchmark interest rates, changes in pricing in the credit markets, and other current economic factors. For equity securities, the OTTI is recognized as a charge to noninterest income. During the
three
months ended
March
31,
2017
and
2016,
the Company incurred
no
OTTI charges related to equity securities.
 
The carrying amount of securities pledged for various purposes totaled
