We consider various factors in the review of investments with an unrealized loss, including the credit quality of the issuer, the duration that the fair value has been less than the adjusted cost basis, the severity of the impairment, the reason for the decline in value and our intent to sell and ability to hold the investment for a period of time sufficient to allow for any anticipated recovery in market value. Based on our review, we did not consider these investments to be other-than-temporarily impaired as of June 30, 2017 or March 31, 2017.
