(1)	Unamortized debt discounts and debt issuance costs of $25.1 million and $19.9 million are included in senior unsecured and secured notes payable as of June 30, 2020 and December 31, 2019, respectively.

We have a $900 million unsecured credit facility which matures in March 2023, with two options to further extend the facility at our election for two additional six month periods and may be expanded three times by up to an additional $500 million upon satisfaction of certain conditions. The interest rate on our unsecured credit facility is based upon the London Interbank Offered Rate ("LIBOR") plus a margin which is subject to change as our credit ratings change. Advances under our credit facility may be priced at the scheduled rates, or we may enter into bid rate loans with participating banks at rates below the scheduled rates. These bid rate loans have terms of 180 days or less and may not exceed the lesser of $450 million or the remaining amount available under our credit facility. Our credit facility is subject to customary financial covenants and limitations. We believe we are in compliance with all such financial covenants and limitations as of June 30, 2020 and through the date of this filing.

Our credit facility provides us with the ability to issue up to $50 million in letters of credit. While our issuance of letters of credit does not increase our borrowings outstanding under our credit facility, it does reduce the amount available. At June 30, 2020, we had no borrowings outstanding on our $900 million credit facility and we had outstanding letters of credit totaling approximately $10.2 million, leaving approximately $889.8 million available under our credit facility.

In April 2020, we issued $750 million aggregate principal amount of 2.800% senior unsecured notes due May 15, 2030 (the "2030 Notes") under our then-existing shelf registration statement. The 2030 Notes were offered to the public at 99.929% of their face amount with a stated rate of 2.800%. We received net proceeds of approximately $743.1 million, net of underwriting discounts and other estimated offering expenses. After giving effect to net underwriting discounts and other estimated offering expenses, the effective annual interest rate on the 2030 Notes is approximately 2.905%. Interest on the 2030 Notes is payable semi-annually on May 15 and November 15, beginning November 15, 2020. We may redeem the 2030 Notes, in whole or in part, at any time at a redemption price equal to the principal amount and accrued interest of the notes being redeemed, plus a make-whole provision. If, however, we redeem the 2030 Notes within three months of the maturity date, the redemption price will equal 100% of the principal amount of the 2030 Notes to be redeemed plus accrued and unpaid interest on the amount being redeemed to the redemption date. The 2030 Notes are direct, senior unsecured obligations and rank equally with all of our other unsecured and unsubordinated indebtedness. We used the proceeds from the offering of the 2030 Notes to repay outstanding balances on our unsecured line of credit and intend to use the remaining balance for general corporate purposes which may include property acquisitions and development in the ordinary course of business, capital expenditures, and working capital where appropriate.

We had outstanding floating rate debt of approximately $99.8 million and $99.6 million at June 30, 2020 and 2019, respectively. The weighted average interest rate on such debt was approximately 1.2% and 3.4% for the six months ended June 30, 2020 and 2019, respectively.

Our indebtedness had a weighted average maturity of approximately 8.8 years at June 30, 2020. The table below is a summary of the maturity dates of our outstanding debt and principal amortizations, and the weighted average interest rates on such debt, at June 30, 2020:
