The Board has approved the rebased first quarter 2008 rail cost adjustment factor (RCAF) and cost index filed by the Association of American Railroads. As required by statute, the RCAF is rebased using the fourth quarter 2007 index value as the denominator and first quarter 2008 index value as the numerator (10/1/07 = 1.00). Rebasing is required
