There were
90
individual debt securities in an unrealized loss position as of
December 31, 2018,
and their combined depreciation in value represented
0.74%
of the debt securities portfolio. These securities included
61
securities in a continuous unrealized loss position for
12
months or longer that the Company does
not
intend to sell, and that it has determined is
not
more likely than
not
going to be required to sell, prior to maturity or recovery. There were
45
individual debt securities in an unrealized loss position as of
December 31, 2017,
and their combined depreciation in value represented
0.57%
of the debt securities portfolio.
 
The Company reviews its investment portfolio quarterly for indications of OTTI. The initial indicator of OTTI for debt securities is a decline in fair value below book value and the severity and duration of the decline. The credit-related OTTI is recognized as a charge to noninterest income and the noncredit-related OTTI is recognized in OCI. The Company incurred
no
credit-related OTTI charges on debt securities in
2018
or
2017.
In
2016
the Company incurred credit-related OTTI charges on debt securities 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. The following table presents the changes in credit-related losses recognized in earnings on debt securities where a portion of the impairment was recognized in OCI during the periods indicated:
