OMAHA, Neb. (AP) — Warren Buffett's company scored a split decision when it was named the lead bidder for Residential Capital's loan portfolio in a bankruptcy court auction. But Berkshire Hathaway Inc. lost to another firm in serving that role for ResCap's mortgage division.

A New York bankruptcy court judge picked Berkshire's $1.442 billion bid on Tuesday as the lead bidder, or stalking horse, for ResCap's loan portfolio.

Nationstar Mortgage, owned by Fortress Investment Group LLC, is the lead bidder for ResCap's mortgage unit with its $2.446 billion bid.

The judge also approved Berkshire's request to have an outside expert review Residential Capital's dealings with its parent company, Ally Financial, before it sought to reorganize.

ResCap spokeswoman Susan Fitzpatrick says the company is encouraged by the interest in bidding while it reorganizes in bankruptcy.
