With the Red Sox's sweep of the Colorado Rockies, Jordan's Furniture, which is owned by Berkshire Hathaway (NYSE: BRK.A), will be rebating the furniture purchases of some 30,000 customers who took advantage of a promotion this spring. Bloomberg News reported that Jordan's had taken out a $20 million insurance policy to pay for it. Is a Buffett-owned insurance carrier on the hook for the $20 million? Will that policy cover the total amount of the rebate? Who'll pay the amount over $20 million, if necessary?

As a lifelong Red Sox fan, I am thrilled by its second World Series win since 2004, but I'm not as euphoric as I was in 2004. I am not sure why, but I think there could be two reasons. First, in 2004 there was the joy of overcoming the Curse of the Bambino -- the Sox had come close in 1967, 1975 and 1986 but failed to close the deal. With the curse reversed, this year the drama was not as intense. Second, in 2004, the Sox came from way behind in the AL East against the arch-enemy Yankees -- this year they came back from three games behind against the Indians -- but the drama was diminished. Nevertheless, with the Red Sox and the 7-0 Patriots, it is great to be living in the sports capital of the U.S.

Meanwhile, Buffett has an interesting little financial problem. At least one of the 30,000 customers who bought furniture during the promotion -- between March 7th and April 16th -- spent $100,000. If we assume that the average customer bought $1,000 worth of furniture, Jordan's is on the hook for $30 million worth of rebates. And if the insurance policy pays $20 million -- whether that came from a Buffett insurance company or not -- that leaves $10 million for the cost of the promotion. It may have been a worthwhile investment if Jordan's got at least $10 million more profit than it would have without the promotion.

It won't matter much to Buffett, but I am sure glad he lost that bet against the Red Sox.
