SVG Capital, the private equity investor which owns Hugo Boss and Birds Eye frozen food firm Iglo, was wanted after seeing a sharp rise in its net asset value (NAV). The 10.9% upward movement in NAV has been driven by a significant increase in the valuation of Hugo Boss, which rose £96.1m between 2010 and 2011 on the back of improved earnings. Iglo jumped £18.1m. Bermuda-based insurance underwriter Catlin wasn't too far behind SVG after its gross premiums written climbed to $4.51bn from $4.07bn the year before, while net premiums written advanced to $3.84bn from $3.32bn. Meanwhile, net income before tax slumped to $71m in 2011 from $406m the year before. Meanwhile, SuperGroup's shares continued to tank following yesterday's announcement that full-year profits would come in at the lower end of expectations. A downgrade from Merchant Securities didn't do much to help either. Rank, a bingo, casino and online gaming company, was also falling after reducing its dividend and seeing a significant decline in revenue at its operations in Spain, though the casino business is coming up trumps.
