Letters of Credit

We have issued letters of credit as the security deposits for certain of our domestic leases. These letters of credit are secured by pledged certificates of deposit which are classified as restricted certificates of deposit on our balance sheets. The terms of our leases require us to renew these letters of credit at least 30 days prior to their expiration dates for successive terms of not less than one year until lease expiration. The terms of our leases also allow us to request a reduction in the amount of these letters of credit at certain points during the lease term if there have been no events of default. As of June 30, 2015, there have been no events of default. Our outstanding letters of credit at June 30, 2015 and December 31, 2014 consisted of the following:
