Caution Concerning Forward-Looking Statements

This current report on Form 8-K contains forward-looking statements as that term is used in the Private Securities Litigation Reform Act of 1995. These statements are based on our current expectations about future events or future financial performance. Forward-looking statements by their nature address matters that are, to different degrees, uncertain, and often contain words such as “may,” “could,” “expect,” “intend,” “plan,” “seek,” “anticipate,” “believe,” “estimate,” “predict,” “potential,” or “continue.” These statements involve known and unknown risks and uncertainties that may cause the events we discuss not to occur or to differ significantly from what we expected. For us, these risks and uncertainties include, among others,

·                  general industry conditions and competition, including current global financial uncertainty;

·                  the impact of market volatility on revenue from asset-based fees;

·                  damage to our reputation resulting from claims made about possible conflicts of interest;

·                  liability for any losses that result from an actual or claimed breach of our fiduciary duties;

·                  financial services industry consolidation;

·                  liability related to the storage of personal information about our users;

·                  a prolonged outage of our database and network facilities;

·                  challenges faced by our non-U.S. operations; and

·                  the availability of free or low-cost investment information.

A more complete description of these risks and uncertainties can be found in our Annual Report on Form 10-K for the year ended December 31, 2011. If any of these risks and uncertainties materialize, our actual future results may vary significantly from what we expected. We do not undertake to update our forward-looking statements as a result of new information or future events.

Investor Relations

22 W. Washington

Chicago, IL 60602

Morningstar Advisor Workstation

1.             The July 10, 2012 announcement that Advisor Group, one of the largest independent broker-dealer networks in the nation, is integrating Morningstar® Advisor WorkstationSM into its Advisor Portal, a single sign-on website advisors use to access client account information and more, is intriguing.  Can you provide a rough estimate of what size Advisor Group is currently as a percentage of Morningstar’s annual revenue?  Of the more than 4,800 Advisor Group independent financial advisors, how many are currently using Morningstar’s research and investment planning software?  How many would you suspect will be users of Morningstar’s research and investment planning software given this exciting announcement?

2

Morningstar Advisor Workstation is a web-based, modular software platform that integrates Morningstar data, analytics, and reports to help advisors serve their investor clients. For perspective, it was our second largest product by revenue in 2011, accounting for 12%, or $77.9 million, of our consolidated revenue. At the end of June 2012, our total user count stood at 160,145 advisors.

While we don’t disclose the percent of revenue that any specifically named client contributes to our firm, and we can’t predict the number of advisors that will ultimately adopt our product, the Advisor Group agreement represents a fairly typical deal for us and is consistent in nature and scope with many other enterprise relationships we have in place.

Former Chief Operating Officer

2.             We noticed that Tao Huang, former Morningstar COO, is now a member of the team of Tur Partners LLC, an investment and advisory firm founded by former Chicago Mayor Richard Daley. Do you have any comment on his joining Tur?

Tao made many contributions to our success during his tenure at Morningstar, and we wish him nothing but the best with his new venture.
