[1] The weighted-average interest rate for short-term borrowings and the current portion of long-term debt was 3.5% as of February 28, 2014 and 3.8% as of February 22, 2013.

[2] We have $250 of unsecured unsubordinated senior notes, due in February 2021 (“2021 Notes”). The 2021 Notes were issued at 99.953% of par value. The bond discount of $0.1 and direct debt issue costs of $3.0 were deferred and are being amortized over the life of the 2021 Notes. Although the coupon rate of the 2021 Notes is 6.375%, the effective interest rate is 6.6% after taking into account the impact of the discount, debt issuance costs and the deferred loss on interest rate locks related to the debt issuance. The 2021 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 2021 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 45 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. Amortization expense related to the discount and debt issuance costs on the 2021 Notes was $0.3 in 2014, 2013 and 2012.

[3] We have a $125 global committed five-year bank facility which was entered into in Q1 2013. As of February 28, 2014 and February 22, 2013, there were no borrowings outstanding under the facility, our availability was not limited, and we were in compliance with all covenants under the facility.In addition, we have a $13.5 unsecured committed revolving bank facility which is utilized primarily for standby letters of credit in support of our self-insured workers’ compensation program. As of February 28, 2014 and February 22, 2013, we had $11.3 and $12.1, respectively, in outstanding standby letters of credit against this facility. We had no draws against our standby letters of credit during 2014 or 2013.

[4] We have unsecured uncommitted short-term credit facilities of up to $3.5 of U.S. dollar obligations and unsecured uncommitted short-term credit facilities of up to $35.1 of foreign currency obligations with various financial institutions as of February 28, 2014. 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, 2014 and February 22, 2013.

[5] We have a note payable with an original amount of $47.0 at a floating interest rate based on 30-day LIBOR plus 3.35%. The loan has a term of seven years and requires fixed monthly principal payments of $0.2 based on a 20-year amortization schedule with a $30 balloon payment due in Q2 2017. The loan is secured by two corporate aircraft, contains no financial covenants and is not cross-defaulted to our other debt facilities.
