* Effective February 15, 2008, the Bank discontinued the publication of the semiannual weighted average cost of funds index for Arizona because there was only one savings institution headquartered in Arizona during the semiannual period July-December 2007. The Bank discontinued the publication of the semiannual weighted average cost of funds index for Nevada effective February 13, 1998, because there were no savings institutions headquartered in Nevada as of September 1, 1997. The cost of funds data from any COFI Reporting Member currently headquartered in Arizona or Nevada will continue to be incorporated into the 11th District semiannual weighted average cost of funds index.

Notice: In July 2009, the Bank discovered that it had made an error in calculating the semiannual cost of funds indices for the period July-December 2008 by including in the calculation the July 2008 interest expenses reported by a COFI Reporting Member that had transferred substantially all of its liabilities to a nonmember during the month of July 2008. As a result of this calculation error, the published 11th District semiannual index was 3 basis points higher and the published California semiannual index was 17 basis points higher than they would have been had the reported interest expenses been excluded. The Bank has confirmed that this interest expense was correctly excluded for the monthly COFI for July 2008. Although the Bank makes a good faith effort to be accurate in the calculation and publication of these indices, it does not warrant, confirm, or guarantee the accuracy of any index that it publishes and, in general, it will not revise or republish any cost of funds index after the publication date. The Bank continues to expressly disclaim any liability to any person for any inaccuracy in any cost of funds index calculated or published by the Bank, regardless of the cause, or for any resulting damages.
