Cost of Funds Report.
Full Name: National Monthly Median Cost of Funds Ratio for OTS-Regulated, SAIF-Insured Institutions. Note: Effective with the January 1999 index, the OTS is using a revised methodology that dampens significantly the month-to-month volatility in the index caused by the change in the number of days in the month. In addition to some other technical modifications, the new methodology assumes an average length of month of 30.4375 days, the average number of days in a month over a four-year period. The index value for January 1999 using the old methodology would have been 4.71%.
