T
here were

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
and
nine
months ended
September 30, 2017,
the Company incurred
no
OTTI charges on debt securities. During the
three
and
nine
months ended
September 30, 2016,
the Company incurred OTTI charges on debt securities owned of
$4.64
million related to the Company’s change in intent to hold certain securities to recovery. The intent was changed to sell specific trust preferred securities in the Company’s investment portfolio primarily to reduce credit concentrations with
two
issuers. 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
and
nine
months ended
September 30, 2017,
the Company incurred
no
OTTI charges related to equity securities. During the
three
months ended
September 30, 2016,
the Company incurred
no
OTTI charges related to equity holdings. During the
nine
months ended
September 30, 2016,
the Company incurred OTTI charges related to certain equity holdings of
$11
thousand.
