Countrywide Financial Corp. on Tuesday said fourth-quarter earnings rose 73 percent as loan volumes and revenue increased, but earnings and revenue came in under estimates.

Shares of Countrywide fell 2.4 percent to settle at $33.44 on Tuesday.

The Calabasas-based residential mortgage lender reported fourth-quarter net income of $638.9 million ($1.03 per share), compared with $369.8 million (61 cents) for the like period a year earlier. Revenues rose 29 percent to $2.6 billion.

Analysts had expected earnings of $1.05 per share on revenue of $2.71 billion.

Within its mortgage banking segment, quarterly earnings rose 67 percent over last year to $434 million. Earnings for its other segments which include banking, capital markets, insurance and global operations jumped 52 percent to $578 million compared to the fourth quarter of 2004.

Countrywide’s mortgage market share grew by more than one quarter from 2004 to 2005, and its servicing portfolio rose 33 percent to $1.11 trillion. The company said its interest income for the quarter jumped 92 percent from year-earlier levels, but interest expense more than doubled.

Net interest income, after provision for loan losses, rose to $645.9 million from $419.6 million a year earlier. Total assets rose to $175.1 billion at Dec. 31 from $128.5 billion in the year-prior period.

“We achieved these results despite an environment that included volatile interest rates; declining production profit margins throughout the industry; and the adverse effects of 2005’s hurricanes, primarily Hurricane Katrina,” said Angelo R. Mozilo, chairman and chief executive, in a statement.

Countrywide expects full-year earnings of $3.80 to $4.80 per share.
