The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same.

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years	Expense Example, with Redemption, 5 Years	Expense Example, with Redemption, 10 Years
| | Thompson LargeCap Fund | USD ($)	115	378	662	1,469

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 45% of the average value of its portfolio.

Principal Investment Strategies of the Fund

The LargeCap Fund normally invests at least 80% of its net assets plus any borrowing for investment purposes in a diversified portfolio of equity securities of large-capitalization companies that at the time of purchase fall within the capitalization ranges of companies in the S&P 500 Index, the Fund's benchmark. Although market capitalizations are constantly changing, as of December 31, 2015, the smallest company in the S&P 500 Index had a market capitalization of $1.76 billion.  The Fund's equity investments included within this 80% may include common stocks, American Depositary Receipts (ADRs), and real estate investment trusts (REITs). Although current income is not its primary objective, the LargeCap Fund anticipates that capital growth will be accompanied by growth through dividend income.

We invest in equity securities that possess most of the following characteristics:

                •      Leading market positions

                •      High barriers to entry and other competitive or technological advantages

                •      High returns on equity and assets

                •      Good growth prospects

                •      Strong management

                •      Relatively low debt burdens

We also generally seek to identify investment opportunities in equity securities of companies that we believe have above-average potential for earnings and dividend growth.

To achieve a better risk-adjusted return on its equity investments, the LargeCap Fund invests in a diversified portfolio of companies, including companies from a blend of industries and style classes. We believe that holding a diverse group of stocks will provide competitive returns under different market environments relative to more narrow investment styles. Our flexible approach to equity investing enables us to adapt to changing market trends and conditions and to invest wherever we believe opportunity exists.

Principal Risks of Investing in the Fund

Like all investments, an investment in the LargeCap Fund is subject to risks, and you could lose money investing in the Fund. The Fund could fail to achieve its investment objective. The LargeCap Fund is suitable if you are looking for capital appreciation by investing in a diverse group of large-sized companies and have a long-term perspective.

An investment in the LargeCap Fund typically is subject to the following principal risks:

Market Risk. It is possible that the Fund's share price and total return may decline as a result of a decline in the value of its portfolio of equity securities. The equity securities in which the LargeCap Fund invests fluctuate in value due to changes in the securities markets, general economic conditions and factors that particularly affect the issuers of these stocks and their industries.

Large Cap Risk. Companies having large capitalizations tend to be more mature than smaller-capitalization stocks. As a result, these types of companies may have fewer opportunities to grow relative to the economy as a whole.

Smaller Cap Risk. Companies having medium and smaller capitalizations are subject to greater price volatility than stocks of large companies and may have lower trading volume and less market liquidity than larger, more-established companies. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or services markets, fewer financial resources and less competitive strength than larger companies.

Style Risk. From time to time we may prefer a certain investment style, such as a growth style or value style, that may underperform and/or be more volatile than other investment styles or the stock markets generally during these periods.

Active Management Risk. Our selection of securities for the LargeCap Fund may not perform as well as expected when those securities were purchased or as well as the securities markets generally.

Depositary Receipts Risk. American Depositary Receipts (“ADRs”) are subject to some extent to the risks associated with directly investing in securities of foreign issuers, including the risk of changes in currency exchange rates, expropriation or nationalization of assets, and the impact of political, diplomatic, or social events.

Real Estate Investment Trusts. Real Estate Investment Trusts (“REITs”) depend on specialized management skills and may have limited diversification and smaller market capitalizations.

Please see page 21 of the Prospectus for detailed information about the risks described above.
