Debt.    On March 1, 2013, instead of remarketing the $212,760,000 of pollution control revenue bonds that were originally issued on our behalf by the Development Authorities of Appling, Burke and Monroe Counties, and were subject to mandatory tender, we elected to redeem the bonds with commercial paper. On April 23, 2013, the Development Authority of Appling County (Georgia), the Development Authority of Burke County (Georgia) and the Development Authority of Monroe County (Georgia) issued, on our behalf, $212,760,000 in aggregate principal amount of tax-exempt pollution control revenue bonds for the purpose of refinancing costs associated with certain of our air or water pollution control and sewage or solid waste disposal facilities. The proceeds were used to repay the outstanding commercial paper utilized to redeem the pollution control revenue bonds that were redeemed on March 1, 2013. Each series of bonds bear interest at 2.40% per annum until April 1, 2020, the initial mandatory tender date. The pollution control revenue bonds are scheduled to mature in 2038 through 2040. Our payment obligations related to these bonds are secured under our first mortgage indenture.

For the six month period ended June 30, 2013, we received advances on Rural Utilities Service-guaranteed Federal Financing Bank loans totaling $70,408,000 for general and environmental improvements at existing plants.
 
In July 2013, we received an additional $589,605,000 in advances on Rural Utilities Service-guaranteed Federal Financing Bank loans for the long-term financing of the Smith Energy Facility and general improvements at existing plants. A portion of these advances was utilized to repay $232,610,000 of outstanding commercial paper classified as long-term debt at June 30, 2013.
