Princeton National Bancorp Inc. reported unaudited consolidated earnings results for the first quarter ended March 31, 2012. For the period, the company reported net interest income of $7,720,000 against $9,357,000 a year ago. Net interest income after provision was $7,645,000 against $7,482,000 a year ago. Income before income taxes was $1,060,000 against $1,647,000 a year ago. Net income available to common stockholders was $686,000 or $0.20 per diluted share against $1,414,000 or $0.42 per diluted share a year ago. Net income available to common stockholders to average assets was 0.27% against 0.52% a year ago. Net income available to common stockholders to average equity was 45.81% against 9.59% a year ago. The decrease in net income is primarily attributable to a lower level of net interest income and fewer gains recognized on the sale of available for sale investment securities, partially offset by a reduction in the provision for loan losses. Total interest income was $8,954,000 compared to the $11,294,000 for the same quarter year ago. Net charge-offs decreased during the first quarter of 2012 to $747,000, compared to net charge-offs of $1.694 million for the first quarter of 2011.
