Source: Morningstar, Inc. as of 9/30/12. Large-cap stocks are represented by the Russell 1000 Index, an index of the 1,000 largest companies in the Russell 3000 Index. Mid-cap stocks are represented by the Russell Midcap Index, which measures the performance of the mid-cap segment of the U.S. equity universe.
