None of the securities were impaired at acquisition, and subsequent declines in fair value are attributable to interest rate increases. We do not intend to sell, and it is not more likely than not that we will be required to sell, these securities before recovery of their amortized cost basis. The issuers continue to make timely interest payments on these securities. Because we believe it is more likely than not we will recover the cost basis of our investments, we did not record any impairment attributable to credit losses.

 

None of the marketable securities purchased during the period had experienced more-than-insignificant deterioration in credit quality since its origination and were therefore not considered “Purchased Financial Assets with Credit Deterioration.”

 

Unrealized losses on our marketable securities and their tax effects are as follows:
