Risk/return bar chart and table
The performance information that follows shows the fund's performance information in a bar chart and an average annual total returns table. The bar chart does not reflect the sales charges of the fund's Class A shares; if it did, the total returns shown would be lower. The information provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual total returns compare with those of the S&P 500 Index, which represents a broad measure of market performance, as well as an additional index over time. The UBS U.S. Allocation Fund Benchmark is an unmanaged benchmark compiled by UBS AM that shows how the fund's performance compares to a benchmark constructed as follows: 65% Russell 3000 Index, 30% Bloomberg US Aggregate Index, and 5% BofA Merrill Lynch US High Yield Cash Pay Constrained Index. The fund's past performance (before and after taxes) is not necessarily an indication of how the fund will perform in the future. Updated performance for the fund is available at www.ubs.com/us/en/assetmanagement/funds/mutual-fund-performance.
After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. In addition, the after-tax returns shown are not relevant to investors who hold fund shares through tax-advantaged arrangements, such as 401(k) plans or individual retirement accounts. After-tax returns for other classes will vary from the Class A shares' after-tax returns shown.
