( 1 ) these losses were recognized as a component of oci ; see note 12 .we conduct periodic reviews to evaluate each security that is impaired .impairment exists when the current fair value of an individual security is below its amortized cost basis .for debt securities available for sale and held to maturity , other-than-temporary impairment is recorded in our consolidated statement of income when management intends to sell ( or may be required to sell ) securities before they recover in value , or when management expects the present value of cash flows expected to be collected to be less than the amortized cost of the impaired security ( a credit loss ) .our review of impaired securities generally includes : 2022 the identification and evaluation of securities that have indications of possible other-than-temporary impairment , such as issuer-specific concerns including deteriorating financial condition or bankruptcy ; 2022 the analysis of expected future cash flows of securities , based on quantitative and qualitative factors ; 2022 the analysis of the collectability of those future cash flows , including information about past events , current conditions and reasonable and supportable forecasts ; 2022 the analysis of individual impaired securities , including consideration of the length of time the security has been in an unrealized loss position and the anticipated recovery period ; 2022 the discussion of evidential matter , including an evaluation of factors or triggers that could cause individual securities to be deemed other-than-temporarily impaired and those that would not support other-than-temporary impairment ; and 2022 documentation of the results of these analyses .factors considered in determining whether impairment is other than temporary include : 2022 the length of time the security has been impaired; .
