(1) Includes capped balances. Unsecured Revolving Credit Facility MAALP maintains a $1.0 billion unsecured credit facility with a syndicate of banks led by KeyBank National Association, or the KeyBank Facility. The KeyBank Facility includes an expansion option up to $1.5 billion. The KeyBank Facility bears an interest rate of the London Interbank Offered Rate, or LIBOR, plus a spread of 0.85% to 1.55% based on an investment grade pricing grid and, as of December 31, 2018, the interest rate was 3.42%. The KeyBank Facility expires in April 2020 with an option to extend for an additional six months. As of December 31, 2018, MAALP had $540.0 million outstanding under the KeyBank facility with another $4.2 million of additional capacity used to support outstanding letters of credit. Senior Unsecured Notes As of December 31, 2018, MAALP had approximately $2.4 billion in principal amount of publicly issued senior unsecured notes and $242.0 million of privately placed senior unsecured notes. The senior unsecured notes had maturities at issuance ranging from seven to twelve years, with an average of 6.5 years remaining until maturity as of December 31, 2018. In May 2018, MAALP publicly issued $400.0 million in aggregate principal of senior unsecured notes, maturing June 2028 with an interest rate of 4.20% per annum, or the 2028 Notes. The purchase price paid by the initial purchasers was 99.403% of the principal amount. The 2028 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 2028 Notes is payable on June 15 and December 15 of each year, beginning on December 15, 2018. The net proceeds from the offering, after deducting the original issue discount of $2.4 million and underwriting commissions and expenses of $2.6 million, were $395.0 million. The 2028 Notes have been reflected net of discount and debt issuance costs in the Consolidated Balance Sheets as of December 31, 2018. In connection with the issuance of the 2028 Notes, MAALP cash settled $200.0 million in forward interest rate swap agreements, which were entered into earlier in the year to effectively lock the interest rate on a portion of the planned transaction, resulting in an effective interest rate of 4.21% over the 10 year life of the 2028 Notes. In July 2018, MAALP retired a $50.0 million tranche of senior unsecured private placement notes at maturity. Unsecured Term Loans MAALP maintains four term loans with a syndicate of banks, one led by KeyBank National Association, or KeyBank, two by Wells Fargo Bank, N.A., or Wells Fargo, and one by U.S. Bank National Association, or U.S. Bank. The KeyBank term loan has a balance of $150.0 million, matures in 2021, and has a variable interest rate of LIBOR plus a spread of 0.90% to 1.75% based on the Company's credit ratings. Both Wells Fargo term loans have balances of $300.0 million, mature in 2022 and 2019, respectively, and have variable interest rates of LIBOR plus spreads of 0.90% to 1.75% and 0.75% to 1.65%, respectively, based on the Company's credit ratings. The interest rate of the Wells Fargo term loan due in 2022 is fixed at 2.32% with a forward swap through the swap's maturity date, January 2020. See Note 7 for additional details on cash flow hedges of interest rate risk. The Wells Fargo term loan due in 2019 was entered into by the Company in December 2018. The U.S. Bank term loan has a balance of $150.0 million, matures in 2020, and has a variable interest rate of LIBOR plus a spread of 0.90% to 1.90% based on the Company's credit ratings. In August 2018, MAALP retired a $250.0 million unsecured term loan with Wells Fargo at maturity. Secured Property Mortgages As of December 31, 2018, MAALP had $476.2 million of fixed rate conventional property mortgages with a weighted average interest rate of 4.6% and a weighted average maturity in 2031.
