Lloyd’s says it is on track to meet financial expectations for the full year, although it is not expecting investment returns to keep improving.

The society’s interim management statement for the third quarter of 2009 shows a £2.5 billion ($4.6 billion) excess of central assets over solvency shortfalls for the September quarter, up marginally from the previous three months.

“Overall, favourable market movements have resulted in investment returns somewhat above the very modest levels which might be predicted from the low prevailing levels of interest rates and risk free yields, both in the third quarter and the year to date,” Lloyd’s said in a statement.

“However, the scope for further such gains is increasingly limited and we expect that current market levels will make it difficult to achieve significant returns in the balance of the year.”
