(The assets, liabilities and results of a wholly-owned subsidiary sold by Cass in the fourth quarter of 2005 are shown as discontinued operations.) Payment and processing fees increased 13% or $1,202,000 compared to the year-earlier period, as transportation invoices were up 6% and dollar volume rose 17% due to new business and heightened activity from existing accounts. Utility invoices processed were up 20%. Net investment income increased 23% or $1,911,000 due mainly to growth in funds generated from processing activities and to the rise in prevailing interest rates. Operating expenses were up 14% or $1,877,000 largely as a result of higher employee costs related to transaction growth. 5 Nine-Month 2006 Results For the nine months ended September 30, 2006, the company earned $1.37 per fully diluted share from continuing operations, a 32% increase from the $1.04 per fully diluted share reported for the same period in 2005.

Operating expenses were up 11% or $4,404,000 in the nine-month year-over-year period, mainly due to the increase in salaries and benefits required to support processing growth.
