Cash and cash equivalents  266.4  (174.1) –  92.3 
Short term cash deposits  –  160.6  –  160.6 
Loans (principal of £2,331.8 million, 2008: £2,282.8 million)  (2,327.0) (26.4) (17.5) (2,370.9)
Finance leases (principal of £111.6 million, 2008: £89.7 million)  (89.8) (13.8) (8.1) (111.7)
  (2,150.4) (53.7) (25.6) (2,229.7)

The difference between the principal value of £2,443.4 million (2008: £2,372.5 million) and the carrying value of £2,482.6 million (2008: £2,416.8 million) are unamortised issue costs of £15.4 million (2008: £15.9 million) and a credit of £54.6 million (2008: £60.2 million) in excess of the original loan proceeds to reflect the fair value of loans owed by subsidiaries acquired in 2003.

Non-cash movements on loans relate to the principal uplift on index linked borrowings and amortisation of loan issue costs offset by the amortisation of debt fair value for the year. Non-cash movements on finance leases relate to the inception of new finance leases on the acquisition of plant and machinery during the year.
