Note 3 — Short-term Investments — Available-for-Sale Securities

During January 2008, Longtrain purchased approximately 1.5 million shares of common stock in the open market for $27.9 million. Subsequently, Longtrain sold a majority of the shares it owned. This investment was classified as a short-term investment available-for-sale security as the Company did not intend on holding the investment long-term.

During the first quarter of 2010, approximately 0.2 million shares of common stock were sold for proceeds of $1.8 million and a realized gain of $0.1 million. During the second quarter of 2010, the remaining approximately 0.2 million shares of common stock were sold for proceeds of $2.3 million and a realized gain of $0.3 million. The cost basis of the shares sold was determined through specific identification.
