Operating expenses were up 5%, or $707,000, as a result of higher employee costs related to transaction growth. Income tax expense decreased slightly due to the growth of the company’s state and municipal bond portfolios.

Net income was $17.8 million, 18% higher than the $15.1 million earned in 2006. Total revenue increased $6.6 million or 8% compared to 2006 primarily due to increased processing volumes and higher fee revenues.

On December 17, 2007, Cass issued a 10% stock dividend to all shareholders of record.

“We are delighted with the 35% growth in transaction volume experienced by our utility invoice processing operations in 2007 and with the 18% increase in year-over-year earnings,” said Lawrence A. Collett, Cass chief executive officer and chairman of the board. “From the larger perspective, it is gratifying that the company produced another solid year of results for our shareholders and that for the fourth consecutive year, we were able to provide a special stock dividend to them over and above the regular quarterly cash dividends we have paid without fail since 1934. We believe Cass is in a strong financial condition to provide a solid base for continued future growth as well as withstand the negative impacts of current difficulties in the financial arena.”
