M1For each fund with at least a three-year history, Morningstar calculates a Morningstar Rating based on a Morningstar Risk-Adjusted Return measure that account for variation in a fund's monthly performance (including the effects of sales charges, loads, and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. The top 10% of funds in each category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars and the bottom 10% receive 1 star. (Each share class is counted as a fraction of one fund within this scale and rated separately, which may cause slight variations in the distribution percentages.) The Overall Morningstar Rating for a fund is derived from a weighted average of the performance figures associated with its three-, five- and ten-year (if applicable) Morningstar Rating metrics. Past performance is no guarantee of future results. Morningstar Rating is for Investor share class only; other classes may have difference performance characteristics.

G1Fund performance may be subject to substantial short-term changes due to market volatility or other factors.
Q1The 7-day Current Yield is calculated based on the income generated by an investment in the fund over a seven-day period and is expressed as an annual percentage rate.
Q2The 7-day Effective Yield is calculated similarly, although this figure is slightly higher than the fund's 7-day Current Yield because of the effects of compounding. The 7-day Effective Yield assumes that income earned from the fund's investments is reinvested and generating additional income.
Q330-day SEC Yield represents net investment income earned by a fund over a 30-day period, expressed as an annual percentage rate based on the fund's share price at the end of the 30-day period. The SEC Yield should be regarded as an estimate of the fund's rate of investment income, and it may not equal the fund's actual income distribution rate, the income paid to a shareholder's account, or the income reported in the fund's financial statements.

Fundamentals - A method of analyzing the strength of a company based on traditional business factors such as profits and management, among several others.
Median Market Cap - Market capitalization (market cap) is the total value of a company's stock, calculated by multiplying the number of outstanding common shares by the current share price. The company whose market cap is in the middle of the portfolio is the median market cap. Half the companies in the portfolio have values greater than the median, and half have values that are less. If there is an even number of companies, then the median is the average of the two companies in the middle.
Weighted Average Market Cap - The average market capitalization represents the average value of the companies held in a portfolio. When that figure is weighted, the impact of each company's capitalization on the overall average is proportional to the total market value of its shares.
Price/Earnings Ratio - A stock value measurement calculated by dividing a company's stock price by its earnings per share, with the result expressed as a multiple instead of as a percentage. (Earnings per share is calculated by dividing the after-tax earnings of a corporation by its outstanding shares.) When this figure is weighted, the impact of each company's P/E ratio is in proportion to the percentage of the fund that the company represents.
Price/Book Ratio - A stock value measurement calculated by dividing a company's stock price by its book value per share, with the result expressed as a multiple instead of as a percentage. (Book value per share is calculated by subtracting a company's liabilities from its assets, then dividing that value by the number of outstanding shares.
1 Yr. EPS Growth - Measures the percent increase or decrease in the earnings of a company over the prior year.
1 Yr. P/E Forecast - Represents the price/earnings (P/E) ratio calculated on the basis of expected earnings for the coming year.
1 Yr. EPS Forecast - Represents the consensus earnings per share estimate for a security one year in the future.
Positive Earning Surprise - Occurs when a company reports earnings greater than consensus estimates.
Negative Earnings Surprise - Occurs when a company reports earnings lower than consensus estimates.
Number of Equity Issues - The number of equity securities, excluding temporary investments, held by a fund on a given date.
Duration - Duration is a weighted average of all bond durations in a fund's portfolio. Duration measures the price sensitivity of a bond or bond fund to changes in interest rates. Specifically, duration represents the approximate percentage change in the price of a bond or bond fund if interest rates move up or down 100 basis points. The duration presented is different depending on the fund type. Please refer to the table below to determine which duration measurement is presented for each fund type:
Duration Measurement and Definition
Approximate percentage change in a bond's price assuming a 100 basis point change in yield and that the bond's expected cash flow does not change when the yield changes.
Approximate percentage change in a bond's price assuming a 100 basis point change in yield and that the bond's expected cash flow changes when yields change.
Average Coupon - Coupon refers to the rate of interest paid on a bond, usually expressed as a percent of its par value. Since bond funds generally own many different bonds with different coupons, a fund's average coupon is the average of all the individual bonds it holds.
Alpha/3yr (annualized) - Shows how a fund did relative to what would have been expected given the fund's Beta and the performance of the benchmark index. For example, an alpha of 1.4 means that the fund outperformed its estimated return (based on market activity alone) by 1.4%.
Beta/3yr - A measure of how volatile a fund's returns have been compared to its benchmark index. The benchmark's beta always equals 1. A fund with a beta greater than 1 had returns that fluctuated more than those of its benchmark. A fund with a beta of less than 1 had returns that fluctuated less.
Rsquared/3yr - Measures what percentage of a fund's returns may be attributed to the returns of a benchmark index. R-Squared ranges from 0 (no correlation between a fund and its benchmark) to 1 (perfect correlation).
Std. Deviation/3yr (annualized) - Defines how widely returns varied from an average over a given period of time. A higher standard deviation means a more volatile fund. For example, a fund with a standard deviation of 6 and an average annual return of 10% saw annualized monthly returns fall within 6 percentage points of that average (or between 4% and 16%) two-thirds of the time.
Sharpe Ratio/3yr - Measures the potential reward offered by a mutual fund relative to its risk level. Developed by William Sharpe, the ratio uses a fund's standard deviation and its excess return to determine reward per unit of risk. The higher the sharpe ratio, the better the fund's historical risk-adjusted performance.
