We have demonstrated our ability to manage the cost base, containing the impact on profit of the like for like volume declines and delivering further significant efficiencies. We are in a strong position to support the significant growth opportunities.
Overall, organic revenue growth was flat, comprising new business of 8.5%, retention of 93% and a like for like decline of 1.5%. Acquisitions less disposals increased revenue by 1.3% and the significant weakening of Sterling, in particular against the Euro and US Dollar, increased reported revenues by 16.2%, resulting in reported revenue growth of 17.5%.

Underlying operating profit from continuing operations, including associates but excluding the amortisation of intangibles arising on acquisition, was £884 million (2008: £662 million), an increase of 33.5% on a reported basis over the prior year. Underlying operating profit increased by £100 million, 12.8% on a constant currency basis. This represents a 70 basis points improvement in margin to 6.5% (2008: 5.8%), or 60 basis points on a constant currency basis.

Operating profit after the amortisation of intangibles arising on acquisition of £7 million (2008: £3 million) was £877 million (2008: £659 million).
The underlying operating profit increased by £100 million, or 12.8%, on a constant currency basis. This represents a 70 basis points improvement in margin to 6.5% (2008: 5.8%).

Additional information on the performance of each region can be found in the regional reviews in the Chief Executive’s statement.
Unallocated overheads for the year were £58 million (2008: £62 million), reflecting delivery of further efficiencies in the central overhead structure.
Underlying net finance cost, excluding hedge accounting ineffectiveness and the impact of revaluing investments and minority interest put options, was £100 million (2008: £73 million). This reflects the impact of exchange rates on the interest payable on US Dollar and Euro denominated debt and the lower interest rates receivable on cash deposits. It also reflects an increased charge in relation to pensions of £11 million (2008: credit of £2 million). We currently expect the underlying net finance cost for 2010 to be around £85 million at current exchange rates.
Other gains and losses include a £7 million (2008: £4 million) cost of hedge accounting ineffectiveness and a £3 million credit (2008: £16 million cost) from revaluing investments and minority interest put options.
Profit before tax from continuing operations was £773 million (2008: £566 million).
On an underlying basis, excluding the amortisation of intangibles arising on acquisition, hedge accounting ineffectiveness and the impact of revaluing investments and minority interest put options, profit before tax from continuing operations increased by 33.1% to £784 million (2008: £589 million).
Income tax expense from continuing operations was £221 million (2008: £169 million).
On an underlying basis, excluding the amortisation of intangibles arising on acquisition, hedge accounting ineffectiveness and the impact of revaluing investments and minority interest put options, the tax charge on continuing operations was £224 million (2008: £171 million), equivalent to an effective tax rate of 29% (2008: 29%). Based on current corporate tax rates applicable to our major countries of operation, we expect the tax rate to average out around the 27% level in the short- to medium-term.
The profit after tax from discontinued operations was £40 million (2008: £53 million).
Our North American business (which includes our operations in the USA, Canada and Mexico) has delivered an excellent performance. Revenues were £5.9 billion (2008: £4.6 billion), with organic growth of 1.6%. Operating profit increased by £49 million, or 12.5% on a constant currency basis, to £441 million (2008: £392 million on a constant currency basis). A focus on driving efficiencies, particularly through the purchasing, logistics and production processes and initiatives to reduce overheads, contributed to a full year margin improvement of 60 basis points on a constant currency basis.
Revenue in Continental Europe totalled £3.4 billion (2008: £3.0 billion) with organic revenue 1.1% lower than last year. However, management of the flexible cost base and further efficiency gains resulted in a robust operating profit performance of £232 million, an increase of 4% on constant currency basis, and margin improvement of 30 basis points to 6.8%.
Revenues were £1.8 billion (2008: £1.9 billion). We have continued to work hard in the UK & Ireland, streamlining the back office and improving productivity. This has enabled us to significantly improve our margins by 60 basis points, despite the difficult economic conditions, with a good increase in operating profit to £114 million (2008: £108 million).
Our Rest of the World businesses have delivered solid organic revenue growth of 2.3%. Operating profit increased by £27 million, or 22% on a constant currency basis, to £148 million (2008: £121 million on a constant currency basis). The acquisition of the remaining 50% of the shares of GR SA in Brazil, completed in March 2008, contributed strongly to this growth. The margin has increased by 100 basis points overall on a constant currency basis to 6.4%.
