SJW Corp. (NYSE:SJW) today reported financial results for the first quarter ended March 31, 2011. Operating revenue was $43.7 million in the quarter compared to $40.4 million in 2010. The $3.3 million increase in revenue reflects cumulative rate increases of $2.4 million, $628,000 in higher customer water usage and new customers compared to a year ago and $300,000 in higher revenue from real estate operations. Net income was $610,000 and diluted earnings per common share were $0.03, compared to $985,000 and $0.05 per share, respectively, in the first quarter of 2010. Water production costs for the quarter ended March 31, 2011 were $15.5 million compared to $14.5 million in 2010, an increase of $1.0 million. The increase in water production cost is primarily attributable to a decrease in use of available surface water supply. Operating expenses, excluding water production costs, for the first quarter were $22.6 million compared to $20.6 million in 2010. The increase of $2.0 million reflects an additional $683,000 of depreciation expense compared to last year, higher administrative and general expenses of $648,000, $384,000 more in taxes other than income tax and an increase of $272,000 in maintenance expenses. Income tax expense for the first quarter decreased to $433,000 in 2011 from $682,000 in 2010 as a result of lower pre-tax income.
