Unsecured Revolving Credit Facility In May 2019, MAALP entered into a $1.0 billion unsecured revolving credit facility with a syndicate of banks led by Wells Fargo Bank, National Association, or Wells Fargo, and fourteen other banks, which is referred to as the Credit Facility. The Credit Facility replaced MAALP’s previous unsecured revolving credit facility, and it includes an expansion option up to $1.5 billion. The Credit Facility bears an interest rate of the London Interbank Offered Rate, or LIBOR, plus a spread of 0.75% to 1.45% based on an investment grade pricing grid. The Credit Facility matures in May 2023 with an option to extend for two additional six-month periods. As of September 30, 2020, there was no outstanding balance under the Credit Facility, while $3.4 million of capacity was used to support outstanding letters of credit. Unsecured Commercial Paper In May 2019, MAALP established an unsecured commercial paper program whereby MAALP may issue unsecured commercial paper notes with varying maturities not to exceed 397 days up to a maximum aggregate principal amount outstanding of $500.0 million. As of September 30, 2020, MAALP had $35.0 million outstanding under the commercial paper program. For the three months ended September 30, 2020, the average daily borrowings outstanding under the commercial paper program were $118.0 million.

In August 2020, MAALP publicly issued $450.0 million in aggregate principal amount of unsecured senior notes, maturing February 2031 with a coupon rate of 1.700% per annum, or the 2031 Notes. The purchase price paid by the purchasers was 99.465% of the principal amount. The 2031 Notes are general unsecured senior obligations of MAALP and rank equally in right of payment with all other senior unsecured indebtedness of MAALP. Interest on the 2031 Notes is payable on February 15 and August 15 of each year, beginning on February 15, 2021. The net proceeds of the offering, after deducting the original issue discount, underwriting commissions and expenses of approximately $5.3 million in the aggregate, were $444.7 million.
