Strong profit growth, disciplined capital spending and working capital control have resulted in excellent operating cash flow of £103.0m (2011: £90.3m). This has allowed £84.7m of acquisitions to be funded, while Group net debt at 31 December 2012 remains modest at £34.2m (2011: net cash £0.1m).

Capital expenditure has continued to be managed carefully. Capital spend (net of asset sales) in 2012 was £47.7m, being 0.9 times depreciation (2011: 0.9 times). There has been a continued focus on cash collection and receivable days at 31 December 2012 are 58 days (31 December 2011: 59 days). Receivables are little changed in the year and a modest increase in inventories (£1.8m) has been more than offset by an increase in payables of £6.4m.
