We amortize intangible assets using the straight-line method over  their expected economic useful lives. Based on acquisitions completed through December 31, 2010, we  expect intangible amortization expense for 2011 and subsequent  years as follows: Other Equity Method Investments.  As of December 31, 2010 and  2009, other equity method investments include our investment in  Morningstar Sweden AB (Morningstar Sweden). Morningstar  Sweden develops and markets products and services customized  for their respective market. Our ownership interest in Morningstar  Sweden was approximately 24% as of December 31, 2010 and 2009. As of December 31, 2009, other equity-method investments also  included our investment in Morningstar Denmark. Our ownership  interest and profit-and-loss-sharing interest in Morningstar Denmark  was 25% at that date. In July 2010, we acquired an additional 75%  ownership in Morningstar Denmark, increasing our ownership inter- est to 100%. Upon acquiring the majority ownership, we recorded  a non-cash holding gain of $4,564,000. This gain represents the  difference between the estimated fair value and the book value of  our investment in Morningstar Denmark at the date of acquisition.  Because Morningstar Denmark is now a wholly owned subsidiary,  we no longer account for our investment using the equity method.  Beginning in July 2010, we consolidate the assets, liabilities, and  results of operations of Morningstar Denmark in our Consolidated  Financial Statements. See Note 7 for additional information concern- ing our acquisition of Morningstar Denmark. Cost Method Investments.
