Available-for-sale debt securities are carried at fair value on the consolidated balance sheets. The Company estimates the lifetime expected credit losses for all available-for sale debt securities in an unrealized loss position. If our assessment indicates that an expected credit loss exists, we determine the portion of the unrealized loss attributable to credit deterioration and record a reserve for the expected credit loss in the allowance for credit losses in technology and academic services in our consolidated income statements. The Company has the ability and intent to hold these investments until recovery. ​
