The Group holds a Revolving Credit Facility in the amount of £230m. This unsecured facility commenced on 3 April 2017 and matures on 3 April 2022. The multi-currency drawings under this facility carry an interest rate of between 0.90% and 1.75% above LIBOR. The applicable margin at 31 December 2018 was 0.90% (2017: 0.90%).

At 31 December 2018, the Group's principal borrowing facility had drawings of £nil (2017: £nil).

All borrowings are classified as financial liabilities measured at amortised cost. Given their short-term nature, the carrying amounts of bank overdrafts approximate their fair value.
