OMAHA, Neb. ( TheStreet) -- The old Shakespearean maxim 'neither a borrower or a lender be' does not apply to Warren Buffett. The Berkshire Hathaway ( BRK.B) chief just completed an $8 billion loan deal to help fund his acquisition of Burlington Northern, and some of the cash that Buffett has doled out in recent years has helped companies from Goldman Sachs ( GS) to General Electric ( GE) and Swiss Re ( SWCEY) deal with the worst of the financial crises. Buffett has already profited handsomely from the Goldman and GE investments. Now, Swiss Re is getting ready to pay back Buffett a convertible loan, on the heels of an earnings report from the world's second-largest reinsurer that, while slightly off expectations, showed that the second-largest reinsurer in the world was no longer in crisis mode. Swiss Re's capital levels rose to $8.3 billion in the last quarter. In 2009, Swiss Re had to go with cup in hand to Omaha and ask Buffett for a loan after its capital levels were crushed by losses on risky assets. Swiss Re had gone to Buffett for a 3 billion franc convertible loan. Swiss Re CFO George Quinn was quoted by Reuter's after Thursday's earnings -- during which the more confident reinsurer also reinstated dividends -- saying that the capital excess "increases our confidence that we can achieve some of most important goals and these include the redemption of the Berkshire security in 2011."
