Lincoln Financial Investments Corporation (the "Adviser") has contractually agreed to waive the following portion of its advisory fee: 0.005% of the Fund's average daily net assets. The agreement will continue through at least April 30, 2027 and cannot be terminated before that date without the mutual agreement of the Fund's Board of Trustees and the Adviser.

•

Market Risk. The value of portfolio investments may decline. As a result, your investment in the Fund may decline in value and you could lose money.

•

Stock/Equity Investing Risk. Stocks and other equities generally fluctuate in value more than bonds and may decline significantly over short time periods. Equity prices overall may decline because stock markets tend to move in cycles, with periods of rising and falling prices.

•

Fund of Funds Risk. The Fund bears all risks associated with the investment strategies of its Underlying Funds, including the possibility that an Underlying Fund may not achieve its investment objective, which could negatively affect the Fund's performance. In addition, among other risks, the Fund indirectly pays a proportional share of the fees and expenses of each Underlying Fund.

•

Issuer Risk. The prices of, and the income generated by, portfolio securities may decline in response to various factors directly related to the issuers of such securities.

•

Asset Allocation Risk. With an asset allocation strategy, the amount invested in various asset classes of securities may change over time. Asset allocation risk could result in an allocation to an underperforming asset class.

•

Active Management Risk. The portfolio investments are actively-managed, rather than tracking an index or rigidly following certain rules, which may negatively affect investment performance. Consequently, there is the risk that the methods and analyses, including models, tools and data, employed in this process may be flawed or incorrect and may not produce desired results.

•

Passive Management Risk. Index funds invest in the securities of an index rather than actively selecting among securities. With an indexing strategy there is no attempt to manage volatility, use defensive strategies, or reduce the effects of any long-term period of poor investment performance.

•

Concentration Risk. Investments that are concentrated in particular industries, sectors or types of investments may be subject to greater risks of adverse developments in such areas of focus than investments that are spread among a wider variety of industries, sectors or investments.

•

Investment Style Factors Risk. There can be no assurance that the multi-factor stock selection process of the Fund will enhance performance. Exposure to such investment factors may detract from performance in some market environments, perhaps for extended periods.

•

Value Stocks Risk. Value stocks tend to be inexpensive relative to their earnings or assets compared to other types of stocks, such as growth stocks. Value stocks can continue to be inexpensive for long periods of time, may not ever realize their potential value, and may even go down in price.

•

Growth Stocks Risk. Growth stocks, due to their relatively high market valuations, typically have been more volatile than value stocks. Growth stocks may not pay dividends, or may pay lower dividends, than value stocks and may be more adversely affected in a down market.

•

Small- and Medium-Cap Company Risk. The value of securities issued by small- and medium-sized companies may be subject to more abrupt market movements and may involve greater risks than investments in larger companies. These less developed, lesser-known companies may experience greater risks than those normally associated with larger companies. Small- and medium-sized companies also may be subject to interest rate risk, which is generally associated with fixed income securities, because these companies often borrow money to finance their operations; therefore, they may be adversely affected by rising interest rates.

•

Exchange-Traded Fund (ETF) Risk. ETFs generally reflect the risks of owning the underlying securities they hold, although lack of liquidity in ETF shares could result in the price of the ETF being more volatile.

•

Interest Rate Risk. When interest rates change, fixed income securities (i.e., debt obligations) generally will fluctuate in value. These fluctuations in value are greater for fixed income securities with longer maturities or durations.

•

Credit Risk. Credit risk is the risk that the issuer of a debt obligation will be unable or unwilling to make interest or principal payments on time. Credit risk is often gauged by "credit ratings" assigned by nationally recognized statistical rating organizations (NRSROs). A decrease in an issuer's credit rating may cause a decline in the value of the issuer's debt obligations. However, credit ratings may not reflect the issuer's current financial condition or events since the security was last rated by a rating agency. Credit ratings also may be influenced by rating agency conflicts of interest or based on historical data that are no longer applicable or accurate.

•

Prepayment/Call Risk. Debt securities are subject to prepayment risk when the issuer can "call" the security, or repay principal, in whole or in part, prior to the security's maturity. When the Fund reinvests the prepayments of principal it receives, it may receive a rate of interest that is lower than the rate on the called security.

•

Mortgage-Backed Securities Risk. The value of mortgage-backed securities (commercial and residential) may fluctuate significantly in response to changes in interest rates. During periods of falling interest rates, underlying mortgages may be paid early, lowering the potential total return (pre-payment risk). During periods of rising interest rates, the rate at which the underlying mortgages are pre-paid may slow unexpectedly, causing the maturity of the mortgage-backed securities to increase and their value to decline (maturity extension risk).

•

Below Investment Grade (Junk Bond) Risk. Below investment grade bonds, otherwise known as "high yield" bonds or "junk" bonds, generally have a greater risk of principal loss than investment grade bonds. Below investment grade bonds are often considered speculative and involve significantly higher credit risk and liquidity risk. The value of these bonds may fluctuate more than the value of higher-rated debt obligations, and may decline significantly in periods of general economic difficulty or periods of rising interest rates and may be subject to negative perceptions of the junk bond markets generally and less secondary market liquidity.

•

Foreign Investments Risk. Foreign investments have additional risks that are not present when investing in U.S. investments. Foreign currency fluctuations or economic or financial instability could cause the value of foreign investments to fluctuate. The value of foreign investments may be reduced by foreign taxes, such as foreign taxes on interest and dividends. Additionally, foreign investments include the risk of loss from foreign government or political actions including, for example, the imposition of exchange controls, the imposition of tariffs, economic and trade sanctions or embargoes, confiscations, and other government restrictions, or from problems in registration, settlement or custody. Investing in foreign investments may involve risks resulting from the reduced availability of public information concerning issuers. Foreign investments may be less liquid and their prices more volatile than comparable investments in U.S. issuers. In addition, certain foreign countries may be subject to terrorism, governmental collapse, regional conflicts and war, which could negatively impact investments in those countries.

•

Emerging Markets Risk. Companies located in emerging markets tend to be less liquid, have more volatile prices, and have significant potential for loss in comparison to investments in developed markets.

•

Foreign Currency Risk. Foreign currency risk is the risk that the U.S. dollar value of investments in foreign (non-U.S.) currencies or in securities that trade in, and receive revenues in, foreign (non-U.S.) currencies, may be negatively affected by changes in foreign (non-U.S.) currency rates. Currency exchange rates may fluctuate significantly over short periods of time.

•

Regional Risk. The Fund will generally have more exposure to the specific market, currency, economic, political, regulatory, geopolitical, or other risks in the regions or countries in which it invests. As a result, the Fund could experience substantial illiquidity, volatility or reduction in the value of its investments, as compared to a more geographically-diversified fund.

•

Derivatives Risk. Derivatives or other similar instruments (referred to collectively as "derivatives"), such as futures, forwards, options, swaps, structured securities and other similar instruments, are financial contracts whose value depends on, or is derived from, the value of an underlying asset, reference rate or index. Derivatives may involve costs and risks that are different from, or possibly greater than, the costs and risks associated with investing directly in securities and other traditional investments. Derivatives prices can be volatile, may correlate imperfectly with price of the applicable underlying asset, reference rate or index and may move in unexpected ways, especially in unusual market conditions, such as markets with high volatility or

•

Futures Risk. A futures contract is considered a derivative because it derives its value from the price of the underlying security or financial index. The prices of futures contracts can be volatile, and futures contracts may be illiquid. In addition, there may be imperfect or even negative correlation between the price of the futures contracts and the price of the underlying securities. Losses on futures contracts may exceed the amount invested.

•

Risk Management Strategy Risk. The success of the Fund's risk management strategy depends in part on Milliman's ability, as the overlay manager, to effectively and efficiently implement its risk forecasts and to manage the strategy for the Fund's benefit. The risk management strategy may depend upon one or more of the overlay manager's proprietary forecasting models and information and data from one or more third parties to support the proprietary forecasting models. There is no guarantee that the models or the data the models are based on will be accurate or that the Fund can achieve or maintain optimal risk targets. The Fund's performance may be negatively impacted in certain underlying markets as a result of reliance on these models. The Fund's performance also may be impacted by the Fund's use of short or long futures positions to implement the risk management strategy. Certain markets could negatively impact the success of the risk management strategy, such as rapidly and unpredictably changing markets, "v-shaped" markets (a sharp market sell-off followed by a strong rally retracing such sell-off), or other extreme or disrupted markets, each of which could cause the Fund to be invested in the underlying market when it declines or to be uninvested when the underlying market appreciates. Milliman seeking to manage currency risk could result in losses if currencies do not perform as expected.

•

Hedging Risk. The success of a hedging strategy cannot be guaranteed. Effective hedging requires correctly assessing the degree of correlation between the performance of the instruments used in the hedging strategy and the performance of the investments in the portfolio being hedged, as well as continual recalculation, readjustment, and execution of hedges in an efficient and timely manner. For example, futures contract short positions may not provide an effective hedge because changes in futures contract prices may not track those of the underlying securities or indices they are intended to hedge.

•

Limited Portfolio Holdings Risk. Because the Fund may hold large positions in a small number of Underlying Funds, an increase or decrease in the value of such securities may have a greater impact on the Fund's value and total return.

•

Liquidity Risk. Liquidity risk is the risk that the Fund cannot meet requests to redeem Fund-issued shares without significantly diluting the remaining investors' interest in the Fund. This may result when portfolio holdings may be difficult to value and may be difficult to sell, both at the time or price desired. Liquidity risk also may result from increased shareholder redemptions in the Fund. Actions by governments and regulators may have the effect of reducing market liquidity, market resiliency and money supply. Liquidity risk also refers to the risk that the Fund may be required to hold additional cash or sell other investments in order to obtain cash to close out derivatives or meet the liquidity demands that derivatives can create to make payments of margin, collateral, or settlement payments to counterparties. The Fund may have to sell a security at a disadvantageous time or price to meet such obligations. The Fund's liquidity risk management program requires that the Fund invest no more than 15% of its net assets in illiquid investments.
