The department shall annually, before October 1, report in writing to the General Assembly concerning the awarding of contracts to small and disadvantaged businesses during the preceding fiscal year. The report shall include a list of all small and disadvantaged businesses that participated as contractors, subcontractors or suppliers during the preceding fiscal year for contracts if the number of contractors under a previously existing contract for the same supply or service is reduced to a single contractor or reduced by more than 50% of the number existing on September 30, 2003. In preparing the report, the department shall verify whether commitments made to small and disadvantaged businesses in the course of awarding these contracts have been maintained.
