2 Risk characteristics are relative to the Russell 2000® Index as of 12/31/11, and for the three-year period. (Other than Sharpe Ratio which is calculated relative to the risk-free rate.)
3 The sector allocation represents the Global Industry Classification Standard (GICS), which was developed by Morgan Stanley Capital International (MSCI) and Standard & Poor's (S&P). The Fund's holdings are allocated to each sector based on their GICS classification. Cash includes short-term investments and net other assets and liabilities.
* Alpha (annualized) is a statistical measurement used to quantify the value added or subtracted by a portfolio manager. Specifically, alpha measures the portfolio's actual return against the portfolio's expected return given the risk of the portfolio as defined by its beta.
* Beta is a statistical measurement of a portfolio's relative sensativity to the benchmark, which acts as a proxy for market risk. The beta between a portfolio and its benchmark is the amount of the units the portfolio will move when the benchmark moves one unit.
* R2 is a statistical measurement that shows the percentage of a portfolio's movements that can be explained by the movement in the benchmark. The numerical value of a portfolio's R2 is always between 0 and 1. An R2 of 1 (or 100%) means that there is perfect correlation in the movement between the portfolio and the benchmark.
* Information Ratio is a measure of the value added per unit of active risk by a manager over the benchmark. The Information Ratio is calculated by dividing the annualized excess return over a benchmark by the annualized standard deviation of excess return.
* Sharpe Ratio is a statistical measurement of the risk-adjusted performance of the portfolio. The ratio is calculated by dividing a portfolio's excess return over the risk-free rate (generally a 3-month T-bill) by the standard deviation of its excess returns. This approximates a portfolio's reward per unit of risk.
