Third quarter earnings were 13% lower than earnings a year ago on revenue increase of 6%. Diluted earnings per share for the third quarter of $0.27 compares to $0.30 reported for the third quarter of 2010 a drop of 10%, our earnings for the quarter were affected by a loss attributable to the SIVs on our balance sheet which netted to a decrease to earnings of approximately $800,000. Now this compares to an $8.7 million increase to earnings due to SIVs in the third quarter of 2010. Now this swing represents approximately $0.03 per share.
Also during the third quarter of 2011, our non-cash asset balances under management experienced significant losses. SEI’s assets under management fell by $19.5 billion during the quarter including a $11.5 billion drop in LSVs assets under management.
And as you will hear later this drop in assets under management is market driven. In addition during the third quarter, we repurchased just under $3.7 million shares of stock at an average price of just over $17 per share. Now that translates over $63 million of stock repurchases during the quarter.
New recurring revenue sales are still slow. For the Investment Managers and Institutional Investors segments good sales quarters, both segments are experiencing delays in conversion.In addition the Advisor segment added a number of new advisors to its roles but did suffer from the loss of assets under management due to market volatility. Banking had a decent sales quarter and they have a number of prospects in the later stage of the sales process and are working hard to close them in the fourth quarter and each of the segment will address their sales events. And we are continuing our investment in GWP and its operational infrastructure so critical to our future. Now during the first quarter, we capitalized approximately $10 million of the Global Wealth Platform development and amortized approximately $6.6 million of previously capitalized development.
