Barcap/Lehman: how good will it be?

Hi,

Just wanted to see what peoples' thoughts were on how good the Barcap/Lehman combination will be a year or two down the line. Business area overlap is minimal (save DCM perhaps) and it appears that although a number of high profile bankers have left Lehman, most have remained behind. Also, although Barclays has a 2.7tn balance sheet it still seems pretty levered vs. competitors, with large exposure derivatives. Thoughts on its survivability?

Thanks
