Berkshire Hathaway, Inc. (Investment Management) Berkshire Hathaway, Inc. (Investment Management) Investment ManagersFinance BHI-IM employs the value investing principles of Benjamin Graham. Their investment approach focuses on buying shares of companies as a long-term investment. The firm seeks to invest in businesses that are easy to understand and have high ROE, exceptional management teams and limited debt. Rather than a diversified stock portfolio, BHI-IM invests in a small number of trusted investments that are overweighed in order to leverage the expected returns. The firm owns stock in a diverse group of over 50 public and private companies in a wide range of industries including, but not limited to, manufacturing, retail, energy and finance. Investments are typically financed using the float from Berkshire Hathaway, Inc.'s insurance operations. Securities are sold when the firm no longer feels comfortable with the fundamentals of a company. 5	OPD	Investment Managers	5
