A. What is Bid Rigging?

Bid rigging (or collusive tendering) occurs when competitors conspire and agree as to who will be the winning bidder. It may take the following forms, amongst others:-

i) Cover/ Complementary/ Courtesy bidding

This is the most frequent way in which bid-rigging is implemented. It occurs when competitors agree on a winner through submitting a bid that is known to be too high to be accepted or one that contains terms that are known to be unacceptable to the purchaser.

ii) Bid Suppression

It involves an agreement among competitors, for one or more of them to refrain from bidding or to withdraw a previously submitted bid so that the designated winner’s bid will be accepted.

iii) Bid Rotation

This entails various ways in which competitors agree to take turns in being the winning bidder.
