      &lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;Our

      Thailand assembly operation uses local currency as its

      functional currency. Assets and liabilities are translated at

      exchange rates in effect at the balance sheet date. Income

      and expense accounts are translated at the average exchange

      rates during the year. Resulting translation adjustments are

      recorded as a separate component of accumulated other

      comprehensive loss. Foreign currency translation, net of

      income taxes, for the thirteen weeks and thirty-nine weeks

      ended June 30, 2013, was a $646,000 loss and a $101,000 loss,

      respectively.&amp;#160;&amp;#160;For the thirteen weeks and

      thirty-nine weeks ended June 24, 2012, foreign currency

      translation, net of income taxes, was a $297,000 loss and a

      $472,000 loss, respectively.&lt;/font&gt;

        &lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"&gt;Transaction

        gains and losses that arise from the exchange rate changes

        on transactions denominated in a currency other than the

        local currency are included in &amp;#8220;Other (expense)

        income, net&amp;#8221; in our condensed consolidated statements

        of operations. For the thirteen weeks and thirty-nine weeks

        ended June 30, 2013, we recognized a foreign currency loss

        of $3,368,000 and $1,249,000, respectively. For the

        thirteen weeks and thirty-nine weeks ended June 24, 2012,

        we recognized a foreign currency loss of $1,090,000 and

        $439,000, respectively. These were primarily related to

        purchases and advances denominated in U.S. dollars made by

        our Thailand operation.&lt;/font&gt;
