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 (UNKNOWN:SLXP.DL), which advances from the S&P SmallCap 600 to replace Gardner Denver (NYSE:GDI). 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 (NYSE:ADC). Elsewhere on that index, DXP Enterprises (NASDAQ:DXPE) will replace True Religion Apparel (NASDAQOTCBB:TRLG.DL). 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.
