Upon acceptance of the Notice of Award and contract signing, the winning bidder should furnish the organization with the required performance security within 10 business days. The performance security provides the organization the winning bidder's guaranty to perform its contractual obligations and could be forfeited in case of breach of contract. The organization should not accept a deficient performance security regardless of the amount of deficiency. The same security should be released by the organization after the winning bidder fulfills its contractual obligations.
