Performance

Performance data represents past performance. Past performance is no guarantee of future results, and current performance may be higher or lower than the performance displayed. The investment return and principal value of an investment will fluctuate such that an investor's shares, when redeemed, may be worth more or less than their original cost. Total returns include reinvestment of dividends and capital gains and are net of all fees and expenses. Prior to April 2002, certain international equity portfolios charged a reimbursement fee to the purchasers of shares of those portfolios.
