⁽¹⁾ The Company evaluated the nature of the investments with a loss position at March 30, 2014 and June 30, 2013, which are primarily obligations of the U.S. government and its sponsored enterprises, municipal bonds and U.S. corporate notes.  In evaluating the investments, the Company considered the duration of the impairments, and the amount of the impairments relative to the underlying portfolio and concluded that such amounts were not other-than-temporary. The Company principally holds securities until maturity, however, they may be sold under certain circumstances.  Unrealized losses on the investments greater than twelve months old were not significant as of March 30, 2014 and June 30, 2013.
