The Fund invests in Underlying Funds according to a relatively stable asset allocation strategy that will not gradually adjust over time and is designed for investors who are already in retirement (i.e., have already passed their retirement year) and may have begun taking systematic withdrawals upon retirement. The Fund has a policy of investing at least 80% of its assets in Underlying Funds that are managed to seek investment returns that track particular market indices. For purposes of the 80% investment policy, the term assets means net assets, plus the amount of any borrowings for investment purposes. Advisors currently expects to allocate approximately 40.00% of the Funds assets to equity Underlying Funds and 60.00% of its assets to fixed-income Underlying Funds. These allocations represent targets for equity and fixed-income asset classes. Target allocations may be changed and actual allocations may vary up to ten percentage points from the targets. Within the equity and fixed-income asset classes, Advisors allocates the Funds investments to particular market sectors (U.S. equity, international equity, fixed-income, non-USD fixed-income, high yield bond, short-term fixed-income and inflation-protected assets) represented by various Underlying Funds. These market sector allocations may vary by up to 10% from the Funds target market sector allocations. The Funds current target market sector allocations for June 30, 2026, which may change, are approximately as follows: U.S. Equity: 26.00%; International Equity: 14.00%; Fixed-Income: 27.61%; Non-USD Fixed-Income: 6.90%; High Yield Bond: 5.49%; Short-Term Fixed-Income: 10.00%; and Inflation-Protected Assets: 10.00%. The asset class and market sector names used herein are intended to reflect the primary type of investment of the Underlying Funds within each of these categories. The Funds target market sector allocations to Underlying Funds may include the Nuveen Equity Index Fund (U.S. Equity); Nuveen Emerging Markets Equity Index Fund and Nuveen International Equity Index Fund (International Equity); Nuveen Bond Index Fund (Fixed-Income); Nuveen International Aggregate Bond ETF (Non-USD Fixed-Income); Nuveen High Yield Corporate Bond ETF (High Yield Bond); Nuveen Short Term Bond Index Fund (Short-Term Fixed-Income) and Nuveen Inflation Linked Bond Fund (Inflation-Protected Assets). As a result of its investments in the Underlying Funds, the Funds returns will reflect investments in a mix of domestic and foreign equities of companies of various sizes and market capitalizations and a variety of domestic and foreign fixed-income instruments of private and governmental issuers of varying maturities and credit qualities. Additional or replacement Underlying Funds for each market sector, as well as additional or replacement market sectors, may be included when making future allocations if Advisors believes that such Underlying Funds and/or market sectors are appropriate in light of the Funds desired levels of risk and potential return at the particular time. The Funds portfolio management team may also add a new market sector if it believes that will help to achieve the Funds investment objective. The relative allocations among Underlying Funds within a market sector may be changed at any time without notice to shareholders. If 10% or more of the Funds assets are expected to be invested in any Underlying Fund or market sector not listed above, shareholders will receive prior notice of such change. Investors should note that the Fund has a significant level of equity exposure and this exposure could cause fluctuation in the value of the Fund depending on the performance of the equity markets generally. As part of the Funds ability to invest in other investment pools or investment products noted above, the Fund may invest in ETFs and exchange-traded notes (ETNs) to gain exposure to various market sectors or securities in order to effect its asset allocation strategy. Additionally, the Fund may use ETFs or ETNs for cash management, hedging or defensive purposes. ETFs or ETNs will be subject to the risks associated with the types of securities or sectors that they track, while ETNs, which are structured as fixed-income obligations, will also be subject to the general risks of fixed-income securities, including credit risk. The Funds asset class allocations, market sector allocations within each asset class, and Underlying Fund allocations within each market sector, as of June 30, 2025, are listed in the chart below. The Fund has relatively fixed asset allocations that will not gradually adjust over time. Underlying Fund allocations may change from year to year. However, as of the date of this Prospectus, Advisors expects that the allocations among the market sectors and Underlying Funds set forth below will be adjusted over time as Advisors implements the addition of Nuveen International Aggregate Bond ETF and Nuveen High Yield Corporate Bond ETF as new Underlying Funds in the new Non-USD Fixed Income and High Yield Bond market sectors, respectively, and a corresponding reduction in allocation to the Nuveen Bond Index Fund.
