[1] The weighted-average interest rate for short-term borrowings and the current portion of long-term debt was 2.5% as of February 28, 2020 and 2.1% as of February 22, 2019.

[2] In 2019, we issued $450 of unsecured unsubordinated senior notes, due in January 2029 (“2029 Notes”). The 2029 Notes were issued at 99.213% of par value. The bond discount of $3.5 and direct debt issuance costs of $4.0 were deferred and are being amortized over the life of the 2029 Notes. Although the coupon rate of the 2029 Notes is 5.125%, the effective interest rate is 5.6% after taking into account the impact of the direct debt issuance costs, a deferred loss on an interest rate lock related to the debt issuance and the bond discount. The 2029 Notes rank equally with all of our other unsecured unsubordinated indebtedness, and they contain no financial covenants. We may redeem some or all of the 2029 Notes at any time. The redemption price would equal the greater of: (1) the principal amount of the notes being redeemed or (2) the present value of the remaining scheduled payments of principal and interest discounted to the redemption date on a semi-annual basis at the comparable U.S. Treasury rate plus 40 basis points; plus, in both cases, accrued and unpaid interest. If the notes are redeemed within 3 months of maturity, the redemption price would be equal to the principal amount of the notes being redeemed plus accrued and unpaid interest. During 2020 and 2019, amortization expense related to the discount and debt issuance costs on the 2029 Notes was

[3] We have a $39.9 note payable with an original amount of $50.0 at a floating interest rate based on 30-day LIBOR plus 1.20%. The loan has a term of seven years and requires fixed monthly principal payments of $0.2 on a 20-year amortization schedule with a $32 balloon payment due in 2024. The loan is secured by two corporate aircraft, contains no financial covenants and is not cross-defaulted to our other debt facilities.

[4] We have a $250.0 global committed bank facility, which was entered into in Q4 2020. This facility amended and restated the former facility, which was scheduled to expire in 2022. As of February 28, 2020 and February 22, 2019, there were no borrowings outstanding under the facilities, our availability to borrow under the facilities were not limited, and we were in compliance with all covenants under the facilities. In addition, we have revolving credit agreements of $34.5 which can be utilized to support bank guarantees, letters of credit, overdrafts and foreign exchange contracts. As of February 28, 2020, we had $14.9 in outstanding bank guarantees and standby letters of credit against these agreements. We had no draws against our standby letters of credit during 2020 and 2019, respectively.

[5] e have unsecured uncommitted short-term credit facilities of up to $5.5 of U.S. dollar obligations and up to $17.7 of foreign currency obligations with various financial institutions available for working capital purposes as of February 28, 2020. Interest rates are variable and determined at the time of borrowing. These credit facilities have no stated expiration date but may be changed or canceled by the banks at any time. There were no borrowings on these facilities as of February 28, 2020 and February 22, 2019.
