Foreign currency translations increased revenue by approximately $4.4 million in 2010, reversing the trend from 2009, when foreign currency translations had a negative impact of $9.0 million. Excluding acquisitions and the impact of foreign currency translations, our non-U.S. revenue rose 5.2% in 2010 and declined 5.5% in 2009. 

International organic revenue (international revenue excluding acquisitions and the impact of foreign currency translations) is considered a non-GAAP financial measure. The definition of inter- national organic revenue we use may not be the same as similarly titled measures used by other companies. International organic revenue should not be considered an alternative to any measure of performance as promulgated under GAAP. 

The tables below present a reconciliation from international revenue to international organic revenue (international revenue excluding acquisitions and the impact of foreign currency translations):

## Largest Products Based on Revenue 

Our five largest products based on revenue—Licensed Data, Investment Consulting, Morningstar Advisor Workstation, Morningstar.com, and Morningstar Direct—made up about 59% of consolidated revenue in 2010. While the percentage of revenue made up by our top five products has remained relatively consistent over the past three years, the relative size of products within the top five has changed each year. Licensed Data became our largest product in 2008 and has remained in that position in 2010 and 2009, partly because of incremental revenue from acquisitions. 

Beginning in 2010, we included revenue from Ibbotson’s plan spon- sor advice service as Retirement Advice revenue. Previously, we included this revenue in Investment Consulting. In 2010 and 2009, as a part of the changes to our organizational structure with a focus on our global product lines, we no longer include Morningstar Site Builder as part of Morningstar Advisor Workstation. Site Builder consists of a set of integrated tools, content, and reports that invest- ment firms can seamlessly add to their existing advisor websites. In addition, we’re continuing to globalize the Premium subscriptions and advertising revenue generated by Morningstar.com websites, which operate in a variety of markets. As a result, we now include advertising revenue for all non-U.S. sites as part of Morningstar. com and have reclassified prior-year product revenue for consistency with current-year presentation.
