Och-Ziff Capital Management's first-quarter loss widened on charges associated with the company's 2007 initial public offering. Adjusted results beat analysts' estimates as management fees in the company's hedge funds increased.

Economic income, or the management and performance fees Och-Ziff receives from the performance in its funds, increased by 29% compared to the first quarter of 2009. Such fees are a key driver of hedge fund companies' earnings. The company also reported more money coming into its funds.
