Top 10 Holdings

Top 10 Equity Holdings

The top 10 companies in which the portfolio invests, measured by a percentage of total investments.

Investment Objective

The Portfolio seeks investment results that correspond to the total return performance of the bond market, as represented by the Barclays U.S. Aggregate Bond Index.

Investment Strategy

The Portfolio seeks to substantially replicate the total return of the securities comprising the Barclays U.S. Aggregate Bond Index ("Barclays Index"), taking into consideration redemptions, sales of additional shares, and other adjustments. Under normal circumstances, the Portfolio will invest at least 80% of its assets in investments with economic characteristics similar to the fixed-income securities represented in the Barclays Index.

Investment Risk

Investment in mutual funds involves risk, including possible loss of principal invested. You could lose money on your investment in the Portfolio or the Portfolio could underperform because of the following risks: the market prices of bonds held by the Portfolio may fall, individual investments of the Portfolio may not perform as expected; and/or the Portfolio’s portfolio management practices may not achieve the desired result. Bond funds are subject to interest rate risk and credit risk. An index fund has operating expenses; a market index does not. Although expected to track its target index as closely as possible while satisfying its investment criteria, the Portfolio will not be able to match the performance of the index exactly. It is not possible to invest directly in an index.

Standard Deviation is a measure of a fund's risk. A standard deviation of 1 means a fund can be expected to produce an annual return that is +/-1% of its average annual return 66% of the time.
Alpha is a measure of the difference between a fund's actual returns and its expected performance, given its level of risk as measured by beta.
Beta is a measure of portfolio risk relative to the market or benchmark. A portfolio beta of 1.0 indicates a risk level equal to that of the fund's benchmark.
Excess Return is return in excess of the risk-free rate or in excess of a benchmark.
R Squared is a statistical measure that represents the percentage of a fund's movements that can be explained by movements in its benchmark index.
Tracking Error is the difference in the return earned by a portfolio and the return earned by the benchmark against which the portfolio is constructed.
Information Ratio is a measure of the consistency of excess return of a mutual fund as compared to its benchmark.
Sharpe Ratio is used to measure risk-adjusted performance. It is calculated by using standard deviation and return in excess of the benchmark to determine reward per unit of risk.

Net expense ratio reflects contractual fee waiver and/or expense reimbursement through April 30, 2014.

Ratings are determined by using S&P, Moody's and Fitch rating services, whose rating categories are reflected above respectively. The letter ratings generally range from AAA (judged to be of the highest quality, with minimal credit risk) to D (the lowest rated class of bonds, typically in default with respect to timely payment of principal or interest). Bonds rated by all three services are assigned the median rating; if a bond is rated by only two agencies, it is assigned the lowest rating; if it is only rated by one agency, it is assigned that rating. Government securities may be rated lower than AAA/Aaa/AAA or may not be rated, and may include foreign government securities. If a bond is not rated by any of the aforementioned rating services, it appears in the "Not Rated" category. Ratings are subject to change.
