FOR IMMEDIATE RELEASE

Morningstar, Inc. to Acquire Hemscott Businesses from Ipreo Holdings LLC

Acquisition to strengthen Morningstar’s global equity database and international presence

CHICAGO, Dec. 17, 2007—Morningstar, Inc., (Nasdaq: MORN), a leading provider of independent investment research, and Ipreo Holdings LLC, a leading global provider of capital markets and investor relations solutions, have entered into a definitive agreement for Morningstar to acquire the Hemscott data, media, and investor relations Web site businesses from Ipreo for $51.6 million in cash, subject to working capital adjustments. The companies expect to complete the transaction in early January, subject to customary closing conditions.

Under terms of the agreement, Morningstar will acquire the following businesses:

· Hemscott Data, which provides financial information on virtually all publicly listed companies in the United States, Canada, the United Kingdom, and Ireland. Hemscott’s global database contains data on more than 19,500 public companies, 170,000 directors and officers, as well as earnings estimates from 68 securities firms in London. Hemscott Data has more than 350 clients including accounting and law firms, brokerages, investment banks, research firms, financial Web sites, and public companies. The business focuses on providing fundamental public company data; executive and director information, including detailed biographies and compensation; and historical pricing and volume data on stocks. Hemscott Data includes Hemscott Guru, a leading business-to-business online research tool that contains up-to-date financial data and directors’ biographies on more than 2,500 UK-quoted companies and 400,000 private companies; and Hemscott Adviser Rankings Guide, a comprehensive listing of more than 1,800 leading providers of professional services to all UK- and Irish-registered companies listed on the London Stock Exchange.

· Hemscott India, which operates a state-of-the-art data collection center in New Delhi, India.

· Hemscott.com, a free investment research Web site in the United Kingdom that attracts more than 320,000 unique users per month, and Hemscott Premium and Premium Plus, subscription-based investment research and data services for executives and high net-worth investors. The Premium services have more than 2,000 subscribers.

· Hemscott IR, a pioneer in online investor relations and corporate communications services in the United Kingdom. Hemscott IR designs, builds, hosts, and maintains investor relations pages and corporate Web sites for more than 540 companies.

“Hemscott is a well-known brand with a large and loyal client base. This acquisition fits with our strategies of building a premier global equity database and expanding our presence outside the United States,” said Joe Mansueto, chairman and chief executive officer of Morningstar. “Hemscott has a leading equity database covering more than 19,500 companies in the United States, the United Kingdom, Canada, and parts of continental Europe. Today Morningstar provides data covering approximately 13,000 equities in the United States, Canada, and Australia. We have some overlap, but this acquisition will significantly strengthen our equity coverage. In addition to its data on a greater number of stocks, Hemscott has decades more data history, as well as management and director information, for U.S., UK, and Canadian stocks. Another crucial component of this acquisition is Hemscott’s sizable data operation in India, where we’ve been interested in establishing a presence for some time.”

Mansueto added, “As part of this agreement, we’re also acquiring a leading investor Web site in the United Kingdom, which dovetails with our belief that there is a growing market for investment information outside the United States. And we’re acquiring a UK-based investor relations Web site business, which is a new market for us but one that directly leverages our data and analytics for IR professionals.”

Scott Ganeles, chief executive officer of Ipreo, said, “At the outset, we had two key strategic objectives. First was to find a buyer that would allow the Hemscott assets to reach their full potential, and becoming part of a premier data and research firm of Morningstar’s caliber will allow them to do just that. Second was to focus Ipreo’s attention on the areas of the market where we can create the greatest value: state-of-the-art software solutions and high-end analytical services for capital markets professionals and corporate officers.”

The Hemscott businesses that Morningstar is acquiring have approximately 200 employees in New Delhi, India, 70 employees in London, and 10 employees in the United States.
