“Despite the challenging economic backdrop we have strong positions in our chosen markets. LGIM delivered positive net flows of £2.6bn, up 29% on Q1 2011, and now has assets under management of £383bn. Risk has achieved sales growth of 8% as consumers seek to protect their families and to secure their retirement incomes.
“We continue to evolve our model both in the UK and in International markets and our diverse product range and broad distribution position us to respond well to regulatory changes. Although we expect market conditions to remain challenging, we remain confident in our ability to continue delivering growth in scale together with substantial cash generation in 2012 and beyond.”
