SCHWAB CHARLES CORP Annual Report, Year Ended Dec 31, 2006

This 10-K filing for The Charles Schwab Corporation for the fiscal year ended December 31, 2006, highlights significant growth and operational performance, particularly driven by its banking segment. The company demonstrated strong profitability with a notable increase in return on average stockholder's equity, reaching 26.34% in 2006, up from 14.23% in 2005. This performance is substantially supported by the expanding Charles Schwab Bank, N.A., which saw its net interest revenue more than double from $164 million in 2005 to $316 million in 2006, reflecting increased loan volumes and higher interest rates on its investment portfolio. Investors will find the robust growth in both assets and net revenues of the banking subsidiary particularly encouraging. The bank's securities available for sale and loans to banking clients have seen substantial increases, contributing to a higher net yield on interest-earning assets. While the overall filing details various business segments, the performance of the banking arm stands out as a key driver of the corporation's financial success during this period, indicating a successful diversification strategy. The report also touches upon risk factors and regulatory environments relevant to its operations.
