Former Royal Bank of Scotland boss Stephen Hester is set to launch a huge fundraising effort this week as part of his bid to revive RSA, the insurer he joined this month.Hester, who is being paid a GBP950,000 salary with the potential for his total package to top GBP5.3 million, is also expected to confirm that the More Than parent is scrapping its final dividend. City analysts believe Thursday's results will show pre-tax profits have slumped to about GBP130m, down from GBP479m in 2012, following a surge in flood claims and an accounting scandal at its Irish subsidiary, which led to the departure of previous chief executive Simon Lee.RSA, which has been hit by a string of profit warnings, slashed a third off its interim dividend in August and analysts at Brewin Dolphin said: "We expect RSA to suspend its final dividend, cut 2014 dividend guidance and potentially also announce a placing or large rights issue of up to GBP500m."However, reports yesterday said the insurer could be seeking to raise as much as GBP800m.A spokeswoman said: "RSA is considering measures to strengthen its balance sheet, including raising capital by way of a rights issue. However, no final decision has been made by the company. Further details will be given when appropriate."RSA last month sought to draw a line under the problems at its Irish arm after a trio of reviews found irregularities at the business did not amount to a group-wide problem.An independent inquiry alleged that "inappropriate collaboration" among a small number of the division's managers was responsible for a GBP200m hit to its finances.
