Our patient investment philosophy

A Patient View

"Time is the friend of the wonderful company, the enemy of the mediocre."
- Warren Buffett

Compels us to wait for the perfect pitch - differentiated companies with strong cash flows, low debt, high quality products or services, significant barriers to entry and low reinvestment requirements.
Allows us to take a long-term view and look past short-term noise with a 3-5 year time horizon in mind.

A Focused Approach

"Invest within your circle of competence." - Warren Buffett

Augments our conviction, especially during crunch time when it matters most.
Leads us to isolate key issues of importance to a company in the midst of market noise.
Results in our portfolio concentration in a limited number of names and industries.

A Team of Independent Thinkers

"If you buy the same stocks as everyone else, you get the same results."
- Sir John Templeton

Encourages us to buy out of favor, misunderstood and ignored stocks.
Leads us to perform our own original, proprietary research.
Persuades us to be benchmark agnostic with very different industry weightings.

Social Screens: The responsibility factor

We believe ethical business practices make good investment sense.

We do not invest in corporations whose primary source of revenue is derived from:

the production or sale of tobacco products or
the manufacture of handguns.

Additionally, we consider a company’s environmental record which includes reviewing research from outside vendors that provide such services, and we encourage portfolio companies to have proactive diversity practices.

For more information, read The Responsibility Factor.

Investing in small cap and mid-cap stocks is more risky and more volatile than investing in large cap stocks. Ariel Fund often invests a significant portion of its assets in companies within the financial services and consumer discretionary sectors and its performance may suffer if these sectors underperform the overall stock market. Performance data quoted represents past performance. Past performance does not guarantee future results. All performance assumes the reinvestment of dividends and capital gains. The investment return and principal value of an investment will fluctuate so that an investor's shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than the performance data quoted.

One of the fund’s benchmarks has been changed from the Russell 2500 Index to the Russell 2000 Value Index as the Adviser believes the new index is more indicative of the market capitalization and style profile of the fund. The Russell 2500™ Value Index measures the performance of the small to mid-cap value segment of the U.S. equity universe. It includes those Russell 2500 companies with lower price-to-book ratios and lower forecasted growth values. The Russell 2000® Value Index measures the performance of the small-cap value segment of the U.S. equity universe. It includes those Russell 2000 companies with lower price-to-book ratios and lower forecasted growth values. Russell® is a trademark of Russell Investment Group, which is the source and owner of the Russell Indexes’ trademarks, service marks and copyrights. The S&P 500® Index is the most widely accepted barometer of the market. It includes 500 blue chip, large cap stocks, which together represent about 75% of the total U.S. equities market.

Average Annual Total Return does not reflect a maximum 4.75% sales load charged prior to 07/15/94.

The inception date for the Institutional Class shares is December 30, 2011. Performance information for the Institutional Class prior to that date reflects the actual performance of the Fund's Investor Class (and uses the actual expenses of the Fund's Investor Class, for such period of time), without any adjustments. For any such period of time, the performance of the Fund's Institutional Class would have been substantially similar to, yet higher than, the performance of the Fund's Investor Class, because the shares of both classes are invested in the same portfolio of securities, but the classes bear different expenses, which are primarily differences in distribution and service fees.

The four-part investment process drives us to take a long-term view, focusing on what matters most through independent thought and research.

The Idea: We read extensively, monitor computer screens, meet with industry experts, and stay abreast of former holdings.

The Science: We seek to purchase companies that trade at a 40% discount to the PMV we have calculated, sell for 13x or less forward cash earnings estimates, or both.

The Art: We surround companies to paint a long-term picture and identify what others are missing. The chief tool is our extensive independent verification network — the many experts we know well. We use strategic questioning of company management and outside experts to identify the key issues affecting an industry or company.

The Decision: We generally purchase only a few companies each year so we weigh our options carefully. Typically, key information is captured in a research report. Our research team vets the idea in a vigorous discussion and each senior research team member weighs in. After this step, the lead portfolio manager makes the final purchase decision.
