Management reviewed various factors in determining whether to recognize an impairment charge related to these unrealized losses, including the current financial and credit market environment, the financial condition and near-term prospects of the issuer of the security, the magnitude of the unrealized loss compared to the cost of the investment, the length of time the investment had been in a loss position and the Company’s intent and ability to hold the investment for a period of time sufficient to allow for any anticipated recovery of market value. As of June 28, 2015 and March 29, 2015, the Company determined that the unrealized losses were temporary in nature and recorded them as a component of accumulated other comprehensive income. |
