Allowance for credit losses or impairment on these marketable securities has not been recognized as these securities are high credit quality, investment grade securities that the Company does not intend to sell and will not be required to sell prior to their anticipated recovery. The change in fair value is primarily due to changes in interest and foreign exchange rates.
