My interest in Berkshire began decades ago when I began following the company in 1988. I have attended the substantial majority of shareholder meetings since the early 1990s and followed the company and Warren Buffett ( Trades, Portfolio )--Berkshire's Chairman, CEO and controlling shareholder--extremely closely since that time. Yet, funds I have managed have owned Berkshire only once for a brief period in late 1999 and 2000. The catalyst for our current investment in Berkshire is our view that the company is currently trading at one of the widest discounts to its intrinsic value in many years, at a time when we expect the operating performance of its subsidiaries to improve as a result of certain managerial and organizational changes at the company. While Mr. Buffett has long been one of most high-profile and closely followed investors in the world, we believe that Berkshire Hathaway's undervaluation is partially explained by the fact that it is one of the least followed and misunderstood mega-cap companies.
