[2] In Q4 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 2019, amortization expense related to the discount and debt issuance costs on the 2029 Notes was

In addition, we have revolving credit agreements of $48.5 which can be utilized to support bank guarantees, letters of credit, overdrafts and foreign exchange contracts. As of February 22, 2019, we had $13.4 in outstanding bank guarantees and standby letters of credit against these agreements. We had no draws against our standby letters of credit during 2019 and 2018, respectively.

There were no borrowings on these facilities as of February 22, 2019 and February 23, 2018.
