Pursuant to the terms of the Tower Securities (see Note 9), the Company is required to establish a securitization escrow account, held by the indenture trustee, into which all rents and other sums due on the towers that secure the Tower Securities are directly deposited by the lessees. These restricted cash amounts are used to fund reserve accounts for the payment of (1) debt service costs, (2) ground rents, real estate and personal property taxes, and insurance premiums related to tower sites, (3) trustee and servicing expenses, (4) management fees, and (5) to reserve a portion of advance rents received from tenants. The restricted cash in the controlled deposit account in excess of required reserve balances is subsequently released to the Borrowers (as defined in the Annual Report on Form 10-K) monthly, provided that the Borrowers are in compliance with their debt service coverage ratio and that no event of default has occurred. All monies held by the indenture trustee are classified as restricted cash on the Company’s Consolidated Balance Sheets.

Payment and performance bonds relate primarily to collateral requirements for tower construction currently in process by the Company. Cash is pledged as collateral related to surety bonds issued for the benefit of the Company or its affiliates in the ordinary course of business and primarily related to the Company’s tower removal obligations. As of June 30, 2013, the Company had $38.6 million in surety, payment and performance bonds for which it was required to post $10.5 million in collateral. As of December 31, 2012, the Company had $35.1 million in surety, payment and performance bonds for which it was required to post $10.5 million in collateral. The Company periodically evaluates the collateral posted for its bonds to ensure that it meets the minimum requirements. The Company had also pledged $2.3 million as of each of June 30, 2013 and December 31, 2012, as collateral related to its workers compensation policy.
