Embedded value NAV rose to 520p from 416p, while the group's solvency buffer improved to £3.7bn from £3.2bn. The group also yesterday floated its Dutch business, Delta Lloyd, on Euronext Amsterdam, which will realise gross proceeds of £1.03bn for a 42% stake."In recent months Aviva has completed a number of strategic initiatives which, together with improving financial markets, significantly increased our capital and balance sheet strength. The outlook for the group's total profitability in 2009 is good despite a reduction in sales driven by continuing customer caution and active management of sales volumes to optimise profitability," chief executive Andrew Moss said.
