Inflation Protected Securities, known as TIPS, are instruments issued by the U.S. Treasury that are structured to provide protection
against inflation, which measures a sustained increase in the prices of goods and services in an economy that can erode the purchasing
power of a currency over time. Interest and principal payments of TIPS are periodically adjusted in step with changes in the inflation
rate. These inflation adjustments for TIPS are applied based on changes in the Consumer Price Index (CPI), while inflation adjustments
for other types of inflation-linked securities may be based on a different inflation index. Inflation-linked securities tend to react
to changes in real interest rates, which represent nominal (stated) interest rates reduced by the expected impact of inflation. For example,
if a 3-year Treasury bond is yielding 5% and inflation expectations for the next 3 years are 2%, the real interest rate is 3%.</p>

investments in inflation-linked securities should provide some protection against the impact of inflation. Investment decisions are based
on the outlooks for inflation, interest rates and the overall economy, as well as the prices and yields of the various securities in
which the fund may invest. For example, if the outlook is one of high or rising inflation, the fund may hold more than 50% of its assets
in inflation-linked securities and, if the adviser believes inflation will be low or falling, the fund may focus more on securities that
are not indexed to inflation (within the fund’s investment program). If interest rates are expected to fall, the fund may purchase
securities with longer maturities in an attempt to seek higher yields and/or capital appreciation. Conversely, if interest rates are
expected to rise, the fund may seek securities with shorter maturities.</p>

may use a variety of derivatives, such as futures, options, foreign exchange currency contracts (forwards), and swaps for a number of
purposes, such as for hedging risk or managing certain exposure. Specifically, the fund uses interest rate futures, and inflation swaps.
Interest rate derivatives would typically be used to manage the fund’s exposure to interest rate changes or to adjust portfolio
duration. Inflation-based swaps, which are derivatives pegged directly to the rate of inflation, are typically used to manage the fund’s
inflation risk or maintain efficient exposure to TIPS and other inflation-linked securities.</p>
The fund
normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in bonds.
The fund’s share price fluctuates, which means you
could lose money by investing in the fund.

income markets:</b></span> Economic and other market developments can adversely affect the fixed income securities markets. At times,
participants in these markets may develop concerns about the ability of certain issuers of debt instruments to make timely principal

to facilitate an orderly market. Those concerns could cause increased volatility and reduced liquidity in particular securities or in

securities:</b></span> In general, the value of an inflation-linked security, including TIPS, will typically decrease when real interest
rates (nominal interest rates reduced by the expected impact of inflation) increase and increase when real interest rates decrease. When
inflation is negative or concerns over inflation are low, the value and income of inflation-linked securities could fall and result in
losses for the fund and during periods of very low inflation, the yield on an inflation-linked security may be negative. Conversely,
during sustained periods of high inflation, the fund’s yield should increase, which may not be repeated. Funds that invest heavily
in inflation-linked securities do not always move in lockstep with inflation because they do not necessarily buy inflation-linked securities
when they are originally issued or hold them until maturity. In addition, the accrual of inflation adjustments on the fund’s holdings
may significantly impact the current level of dividends actually paid to shareholders. Changes in inflation rates and/or interest rates
may cause the fund’s yield to vary substantially over time.</p>

conditions:</b></span> The value of the fund’s investments may decrease, sometimes rapidly or unexpectedly, due to factors affecting
an issuer held by the fund, particular industries, or the overall securities markets. A variety of factors can increase the volatility
of the fund’s holdings and markets generally, including geopolitical developments (such as trade and tariff arrangements, sanctions,
and cybersecurity attacks), recessions, inflation, rapid interest rate changes, war, military conflict, acts of terrorism, natural disasters,
and outbreaks of infectious illnesses or other widespread public health issues (such as pandemics) and related governmental and public
responses. Certain events may cause instability across global markets, including reduced liquidity and disruptions in trading markets,
while some events may affect certain geographic regions, countries, sectors, and industries more significantly than others. Government
intervention in markets may impact interest rates, market volatility, and security pricing. These adverse developments may cause broad
declines in market value due to short-term market movements or for significantly longer periods during more prolonged market downturns.</p>

rates:</b></span> A rise in interest rates typically causes the price of a fixed rate debt instrument to fall and its yield to rise.
Conversely, a decline in interest rates typically causes the price of a fixed rate debt instrument to rise and the yield to fall. The
prices and yields of inflation-linked bonds are directly impacted by the rate of inflation as well as changes in interest rates. Generally,
funds with longer weighted average maturities and durations carry greater interest rate risk. Changes in monetary policy made by central
banks and/or governments are likely to affect the interest rates or yields of the securities in which the fund invests.</p>

and asset-backed securities:</b></span> Investments in mortgage-backed securities and other types of asset-backed securities are subject
to interest rate risk, prepayment and extension risk, credit risk, and the risk of underperformance by the underlying pools of assets.
Mortgage-backed securities and asset-backed securities tend to be more sensitive to changes in interest rates than traditional bonds
and other debt securities. Early repayments of principal on underlying assets may expose the fund to a lower rate of return upon reinvestment
of principal and the value of securities with prepayment features may not increase as much as other fixed income securities when interest
rates are declining. In addition, the value of these securities may fluctuate in response to the market’s perception of the creditworthiness
of the issuers and there is no assurance that any guarantors or insurers of such securities will meet their obligations.</p>

and extensions: </b>The fund is subject to prepayment risks because the principal on mortgage-backed securities, asset-backed securities,
or any debt instrument with an embedded call option may be prepaid at any time, which could reduce the security’s yield and market
value. The rate of prepayments tends to increase as interest rates fall, which could cause the average maturity of the portfolio to shorten.
Extension risk may result from a rise in interest rates, which tends to make mortgage-backed securities, asset-backed securities, and
other callable debt instruments more volatile.</p>

The fund may not be able to meet requests to redeem shares issued by the fund without significant dilution of the remaining shareholders’
interests in the fund. In addition, the fund may not be able to sell a holding in a timely manner at a desired price. Reduced liquidity
in the bond markets can result from a number of events, such as limited trading activity, reductions in bond inventory, and rapid or
unexpected changes in interest rates. Markets with lower overall liquidity could lead to greater price volatility and limit the fund’s
ability to sell a holding at a suitable price.</p>

markets with potential governmental interference, varying regulatory, auditing, and accounting standards, and settlement and clearance
practices that differ from those of U.S. issuers. Investment in non-U.S. securities also carries currency risk. Any attempts to hedge
currency risk could be unsuccessful. Such investments may have higher transaction costs compared with U.S. markets. Investments in emerging

</b></span>The use of derivatives exposes the fund to additional volatility and potential losses and the fund may not achieve the purpose
of using the derivative. A derivative involves risks different from, and possibly greater than, the risks associated with investing directly
in the reference or assets on which the derivative is based, including liquidity risk, valuation risk, correlation risk, market risk,
interest rate risk, leverage risk, counterparty and credit risk, operational risk, management risk, legal risk, and regulatory risk.
Derivatives can be highly volatile, illiquid, and difficult to value, and changes in the value of a derivative may not properly correlate
with changes in the value of the underlying asset, reference rate, or index. The fund could be exposed to significant losses if it is
unable to close a derivatives position due to the lack of a liquid secondary trading market. The prices of derivatives may move in unexpected
ways, especially in abnormal market conditions. Derivatives also expose the fund to settlement risk, such as if the fund is required
to acquire, buy, or sell the underlying reference or asset at an undesirable price, has challenges with offsetting transactions, or risks
associated with cash settlement. Certain derivatives are also subject to counterparty risk, which is the risk that the derivative counterparty
will not fulfill its contractual obligations. The use of derivatives includes the risk of potential operational issues. Derivatives are
exposed to legal risks, such as the legality or enforceability of a contract. The adviser may not be able to accurately predict the direction
of prices, economic factors, or other associated risks which could cause loss in value or impair the fund’s efforts to reduce overall
volatility. New regulations may make derivatives more costly, limit availability, or otherwise affect their value or performance.</p>
