McGraw-Hill Financial's S&P Dow Jones Indices is making several adjustments to a pair of its signature products. On July 30 after market close, the S&P MidCap 400 will be the new home of Salix Pharmaceuticals (NASDAQ: SLXP), which advances from the S&P SmallCap 600 to replace Gardner Denver (IR -1.42%). The latter company agreed to be acquired by KKR earlier this month.

The position vacated by Salix in the S&P SmallCap 600 will be filled by Agree Realty (ADC -0.51%). Elsewhere on that index, DXP Enterprises (DXPE -2.30%) will replace True Religion Apparel (NASDAQ: TRLG). As with Gardner Denver in the S&P MidCap 400, True Religion Apparel is being acquired, in this case by private equity firm TowerBrook Capital Partners.
