Insurance Networking News reports that Moody’s has assigned an Aa2 rating to $1.5 billion of senior unsecured notes being issued by Berkshire Hathaway Finance Corp. Net proceeds are expected to be used to repay a like amount of BHFC notes maturing in January 2011. Moody’s says the rating outlook for Berkshire and BHFC is stable. BHFC, part of Berkshire’s finance and financial products segment, provides financing to Vanderbilt Mortgage and Finance Inc. (Vanderbilt), a wholly owned subsidiary of Clayton Homes Inc. (Clayton), which is indirectly wholly owned by Berkshire. Vanderbilt, in turn, provides installment financing to certain purchasers of homes sold by Clayton and also makes bulk purchases of manufactured housing loans from banks and other lenders. Moody’s says BHFC accounted for about 20 percent of Berkshire’s consolidated debt outstanding as of Sept. 30, 2010. Berkshire guarantees all of BHFC’s borrowings.
