We(212) expect to report net income of approximately $300 million in the first quarter of 2006 compared to $176 million in the first quarter of 2005. We expect our total net revenues to be approximately $2.9 billion, an increase of approximately $1.3 billion, or 79%, compared to the first quarter of 2005. Net revenues for the first quarter of 2006 include approximately $950 million from the consolidation of certain private equity funds and other entities, compared to $157 million in the first quarter of 2005. Net income is unaffected by this consolidation as we record offsetting minority interests and related operating expenses. The increase in net revenues also reflects higher revenues across all of our Investment Banking businesses. We expect our total expenses for the first quarter of 2006 to be approximately $1.5 billion, an increase of approximately $290 million, or 23%, compared to the first quarter of 2005, primarily reflecting higher employee compensation and benefits expenses. 325-2000
