Performance data quoted represents past performance, which is no guarantee of future results. Current performance may be lower or higher than the performance quoted. Please refer to Important Risk Information. The principal value and return of an investment will fluctuate so that your shares, when redeemed, may be worth more or less than their original cost. Performance reflected at NAV does not include the Fund's maximum front-end sales load of 2.25% for Class A shares for the following funds: Convertible Fund, Global Convertible Fund, Market Neutral Income Fund, High Income Opportunities Fund, Short-Term Bond Fund, and Total Return Bond Fund. Performance reflected at NAV does not include the Fund's maximum front-end sales load for Class A shares of all other listed funds which is 4.75%. Had it been included, the Fund's return would have been lower.

*1-year, 3-year, 5-year, 10-year and since inception returns are as of the most recent month-end. Average annual total return measures net investment income and capital gain or loss from portfolio investments as an annualized average. All performance shown assumes reinvestment of dividends and capital gains distributions. Performance shown reflects an expense reimbursement that improved results. Load-adjusted returns are adjusted for the maximum front-end sales load of 2.25% for Class A shares for the following funds: Convertible Fund, Global Convertible Fund, Market Neutral Income Fund, High Income Opportunities Fund, Short-Term Bond Fund, and Total Return Bond Fund. The maximum front-end sales load for Class A shares of all other listed funds is 4.75%. There is a 1% contingent deferred sales charge for C shares on certain redemptions within the first year of purchase. Class C shares have been adjusted for the contingent deferred sales charge (CDSC). There are no contingent deferred sales charges or distribution or service fees with respect to Class I shares. The minimum initial investment required to purchase each Fund's Class I shares is $1 million. Class I shares are offered primarily for direct investment by investors through certain tax-exempt retirement plans (including 401(k) plans, 457 plans, employer-sponsored 403(b) plans, profit sharing and money purchase pension plans, defined benefit plans and non qualified deferred compensation plans) and by institutional clients, provided such plans or clients have assets of at least $1 million. Class I shares may also be offered to certain other entities or programs, including, but not limited to, investment companies, under certain circumstances.
