(1) In connection with our outstanding 2007 Junior Notes, we executed an RCC, which we amended on June 29, 2015, for the benefit of persons that buy, hold, or sell a specified series of our long-term indebtedness (covered debt). Our 6.20% Senior Notes due April 1, 2033 have been designated as the covered debt under the RCC. The RCC provides that we may not redeem, defease, or purchase, and that our subsidiaries may not purchase, any 2007 Junior Notes on or before May 15, 2037, unless, subject to certain limitations described in the RCC, we have received a specified amount of proceeds from the sale of qualifying securities. (2) Variable interest rate reset quarterly. The rates were 6.72% and 2.27% as of December 31, 2022 and 2021, respectively. Until their expiration on November 15, 2021, we had two interest rate swaps with a combined notional value of $250.0 million. The swaps provided a fixed interest rate of 4.9765% on $250.0 million of the outstanding notes. See Note 18, Derivative Instruments, for more information on the two interest rate swaps. (3) The terms of Integrys's 2013 6.00% Junior Notes, due August 1, 2073, provide that, effective August 2023, they will bear interest at a variable rate, which we expect to based off of SOFR, and will reset quarterly.

Under the terms of the Indenture, substantially all property owned by PGL is pledged as collateral for these outstanding debt securities. PGL has used certain First Mortgage Bonds to secure tax exempt interest rates. The Illinois Finance Authority has issued Tax Exempt Bonds, and the proceeds from the sale of these bonds were loaned to PGL. In return, PGL issued $100 million of collateralized First Mortgage Bonds. (5) NSG's First Mortgage Bonds are subject to the terms and conditions of NSG's First Mortgage Indenture dated April 1, 1955, as supplemented. Under the terms of the Indenture, substantially all property owned by NSG is pledged as collateral for these outstanding debt securities.
