Debt

9 Months Ended

Mar. 31, 2021

The Company has two series of fixed-rate notes with 10-year, staggered maturities for an aggregate principal amount of $2.0 billion (collectively the “Notes”). The Notes are senior unsecured obligations, and interest is payable in arrears, semi-annually.

During the three months ended September 30, 2020, the Company issued $1.0 billion of senior notes due in 2030 bearing a fixed interest rate of 1.25%. The Company also redeemed $1.0 billion of senior notes bearing a fixed interest rate of 2.25%. In connection with the senior notes issuance, the Company also terminated several derivative contracts in place to hedge exposure in changes in benchmark interest rates for the senior notes issued with an aggregate notional amount totaling $1.0 billion (of which $400.0 million were entered into during fiscal year 2020 and $600.0 million were entered into on the day of issuance). Since these derivative contracts were classified as cash flow hedges, the unamortized loss of $43.6 million was deferred in accumulated other comprehensive income and will be amortized to earnings over the life of the Notes as the interest payments are made.

The principal amounts and associated effective interest rates of the Notes and other debt as of March 31, 2021 and June 30, 2020, are as follows:


Debt instrument	Effective Interest Rate	March 31, 2021		June 30, 2020
