Adjusteda revenue for the year was down 6%, in line with our strategy to de-emphasise low margin business and including the impact of divestments. This includes a £35m negative impact from foreign exchange movements, primarily reflecting lower IP Exchange volumes and equipment sales.
Adjusteda operating costs for the year were down 8% mainly reflecting the decline in IP Exchange volumes and equipment sales and lower labour costs from our ongoing restructuring programme. Adjusteda EBITDA for the year was up £71m reflecting the reduction in operating costs and certain one-offs, more than offsetting the impact of lower revenue.
Depreciation and amortisation was down 13% for the year due to closure of certain projects in the prior year.
Capital expenditure was down 12% for the year reflecting ongoing rationalisation and our strategy to become a more asset light business. Normalised free cash flowb for the year improved by 151% to £296m, reflecting higher EBITDA, lower capital expenditure and improved working capital.
Total order intake was £3.3bn, down 15% year on year continuing to reflect a shift in customer behaviour, including shorter contract lengths and greater prevalence of usage-based terms.
a Adjusted measures exclude specific items, as explained in the Additional Information on page 185. b Free cash flow after net interest paid, before pension deficit payments (including the cash tax benefit of pension deficit payments) and specific items. c Openreach comparatives have been re-presented to reflect the transfer of Northern Ireland Networks from Enterprise to Openreach.
