[1] The Pennsylvania Economic Development Authority (PEDFA) bond and The Pollution Control Financing Authority of Salem County bonds that are serviced and secured by Power Pollution Control Notes and PSE&G Pollution Control Bonds, respectively, are variable rate bonds that are in weekly reset mode. The PEDFA bond is backed by a three-year letter of credit that expires in November 2014. The Power Pollution Control Note backing the PEDFA bond has been reclassified as debt due within the year.

[2] Secured by essentially all property of PSE&G pursuant to its First and Refunding Mortgage.

[3] Non-recourse financing transactions consist of loans from banks and other lenders that are typically secured by project assets and cash flows and generally impose no material obligation on the parent-level investor to repay any debt incurred by the project borrower. The consequences of permitting a project-level default include the potential for loss of any invested equity by the parent.

[4] PSEG entered into various interest rate swaps to hedge the fair value of certain debt at Power. The fair value adjustments from these hedges are reflected as offsets to long-term debt on the Consolidated Balance Sheet. For additional information, see Note 16. Financial Risk Management Activities.

[5] In September 2009, Power completed an exchange offer with eligible holders of Energy Holdings’ 8.50% Senior Notes due 2011 in order to manage long-term debt maturities. Since the debt exchange was between two subsidiaries of the same parent company, PSEG, and treated as a debt modification for accounting purposes, the resulting premium was deferred and is being amortized over the term of the newly issued debt. The deferred amount is reflected as an offset to Long-Term Debt on PSEG’s Consolidated Balance Sheets.
