28 Financial Assets and Liabilities The Group’s financial assets and liabilities include cash, loans receivable, borrowings, derivative financial assets and liabilities, trade creditors and trade debtors. Borrowings as at 31 March 2015 represent bank term loans, private placement loan notes, finance lease obligations, index-linked debt and irredeemable debenture stock. The purpose of the Group's borrowings is to finance the Group’s operations. It is, and has been throughout the year and the previous year under review, the Group’s policy that no trading in financial instruments shall be undertaken. The Group’s policy in respect of cash, loans receivable and borrowings is to maintain flexibility with both fixed and floating interest rates and long and short-term debt while not exposing the Group to significant risk of market movements (see below). As at 31 March 2015, derivative financial liabilities represent floating to fixed interest rate swaps used as cash flow hedges to reduce the Group’s risk to changes in LIBOR.

These include £35,000,000 (2014: £35,000,000) of loans that are floating rate but floating to fixed interest rate swaps have been entered into as at 31 March 2015 in respect of these loans that commence cash flows in October 2015 when these loans will therefore become fixed rate when combined with these swaps. Fixed rate financial liabilities include fixed rate bank term loans of £15,763,000 (2014: £15,763,000) and floating rate bank term loans of £46,500,000 (2014: £46,500,000) that are effectively swapped to fixed rate by cash flow hedges using floating to fixed interest rate swaps where cash flows under the swaps have commenced. The Group's trade debtors and trade creditors are not subject to interest unless considered to be overdue.
