Loans, overdrafts and long-term debt - Summary (Details) - USD ($) $ in Millions	Feb. 02, 2019	Feb. 03, 2018
Debt Disclosure [Abstract]
Senior unsecured notes due 2024, net of unamortized discount	$ 399.0	$ 398.9
Senior unsecured term loan	294.9	326.2
Bank overdrafts	40.1	14.2
Total debt	734.0	739.3
Less: Current portion of loans and overdrafts	(78.8)	(44.0)
Less: Unamortized capitalized debt issuance fees	(5.6)	(7.1)
Long-term debt	$ 649.6	$ 688.2

Carrying value as of the balance sheet date of payments made in excess of existing cash balances, which will be honored by the bank but reflected as a loan to the entity. Overdrafts generally have a very short time frame for correction or repayment and are therefore more similar to short-term bank financing than trade financing.
