On June 13, 2017, we announced that we planned to close offerings of $648.0 million aggregate principal amount of private placement senior unsecured notes (both fixed and floating rate). We funded $250.0 million on June 27, 2017, $300.0 million on August 2, 2017 and $98.0 million on August 4, 2017, which was used in part to repay our $300.0 million August 3, 2017 debt maturity. The weighted average maturity of the $598.0 million of senior fixed rate notes is 11.6 years and their weighted average interest rate is 4.04% after giving effect to hedging gains. The interest rate on the $50.0 million of floating rate notes would be 3.02% using three-month LIBOR on October 24, 2017. In 2016 and 2017, we entered into pre-issuance interest rate hedging transactions related to the $300.0 million August 3, 2017 maturity private placement. We realized a cash gain of approximately $8.3 million on the hedging transaction that will be recognized on a pro rata basis as a reduction in our reported interest expense over the life of the debt.
