The operation of the prize bond scheme was put out to tender in October 1988. The invitation to tender was advertised in the national newspapers on 7 October 1988. The only qualifying condition specified was that the successful tenderer be able to produce promptly a tax clearance certificate from the Revenue Commissioners.
Four tenders were received and were evaluated on the basis of price and the soundness of the proposals. Following this evaluation, a ten year contract was awarded to two of the tenderers jointly, the Foreign Exchange Company of Ireland based in Killorglin, County Kerry, and An Post. This contract was signed on 9 May 1989, and covers the period to 30 April 1999.
