Investment Goal
Each Fund's primary investment goal is to provide, through investment in a
portfolio of fixed income obligations, as high a level of income as is
consistent, in the view of the Funds' investment adviser, with safety of
capital. Each Fund also seeks to reduce fluctuations in its share price
compared to longer term portfolios. No assurance can be given that these
goals will be achieved.
Principal Investment Strategy of the Funds
Limited Term U.S. Government Fund attempts to reach its primary goal by
investing mainly in obligations issued or guaranteed by the United States
Government or its agencies and instrumentalities, mortgage-backed
securities issued or guaranteed by U.S. agencies, and in participations in
such obligations or in repurchase agreements secured by such obligations.
Limited Term Income Fund attempts to reach its primary goal by investing
mainly in investment grade short and intermediate maturity bonds, including
some foreign securities, and in mortgage-backed securities. Investment
grade securities are rated in the four highest grades of a recognized
ratings agency. Each Fund also seeks to reduce fluctuations in its share
price compared to longer term portfolios by maintaining a portfolio of
investments with a dollar-weighed average portfolio maturity of not more
than five years.
Principal Risks
The value of each Fund's shares and its dividends will change in response
to changes in interest rates. When interest rates increase, the value of
each Fund's investments declines and the Fund's share value is reduced.
Value changes in response to interest rate changes may be more pronounced
for mortgage-backed securities owned by the Funds. Additionally, decreases
in market interest rates may result in prepayments of certain obligations
each Fund will acquire. These prepayments may require a Fund to reinvest
at a lower rate of return.
Some investments owned by the Funds may be subject to default or delays in
payment, or could be downgraded by rating agencies, reducing the value of a
Fund's shares. A fall in worldwide demand for U.S. Government securities
or general economic decline could lower the value of these securities.
Additionally, foreign securities the Income Fund may purchase are subject
to additional risks, including changes in currency exchange rates which may
adversely affect the Fund's investments, political instability,
confiscation, inability to sell foreign investments and reduced legal
protections for investments. The loss of money is a risk of investing in
either of the Funds, and when you sell your shares they may be worth less
than what you paid for them.
An investment in either of the Funds is not a deposit in any bank and is
not insured or guaranteed by the Federal Deposit Insurance Corporation or
any other government agency.
Past Performance of Limited Term U.S. Government Fund
The following information provides some indication of the risks of
investing in Limited Term U.S. Government Fund by showing how the Fund's
investment results vary. The bar chart shows how the annual total returns
for Class A shares have been different in each full year shown. The

performance to the Lehman Brothers Intermediate Government Bond Index, a

necessarily an indication of how the Fund will perform in the future.

3. customers of fee for service financial advisors;
4. shareholders investing through a dealer's wrap program;

annual expenses and a 1/2 of 1% contingent deferred sales charge if
redeemed within one year of purchase.
The minimum purchase to open an account is $5,000 for both Class A and
Class C shares. Minimum additional purchase for any account is $100.
Minimum account size for Class A and Class C shares is $1,000, and accounts
falling below that amount may be subject to mandatory redemption.
Purchases may be made by mail, through your financial advisor or by
telephone.
Redeeming Fund Shares
You can withdraw money from your Fund account on any Fund business day by
redeeming some or all of your shares (selling them back to the Fund either
directly or through your financial advisor). Your shares will be purchased
by the Fund at the net asset value next computed after your order is
received in proper form. If your purchase was subject to a contingent
deferred sales charge within one year of purchase, the charge will be
deducted. You may redeem Fund shares by mail, through your financial
advisor, or by telephone, if you have previously signed up for the
telephone redemption feature.
Distributions and Taxes
Each Fund distributes substantially all of its net income and realized
capital gains to shareholders each year. Each Fund declares its net
investment income daily and distributes it monthly. Each Fund will
distribute any net realized capital gains at least annually. Distributions
are reinvested automatically in additional shares unless you elect to
receive them in cash. Distributions representing net investment income and
net short-term capital gains will be taxable to recipient shareholders as
ordinary income for federal income tax purposes. Any distributions of
long-term capital gains are taxed as long-term capital gains for federal
income tax purposes. State income tax treatment of shareholder
distributions may vary from federal treatment of distributions.
