Which act mandates contractors disclose actual costs to aid in price determinations?

The Truth in Negotiations Act (TINA) is the legislation that mandates contractors to disclose their actual costs during negotiations for government contracts. The purpose of this act is to ensure that the government can make informed price determinations based on transparent and accurate cost data. By requiring contractors to provide certified cost or pricing data, TINA promotes fairness and integrity in the government procurement process. This requirement helps prevent the government from overpaying for goods and services by ensuring that the prices proposed are based on realistic and substantiated costs.

The other choices pertain to different aspects of contracting and compliance but do not specifically focus on the requirement for contractors to disclose their actual costs for price determination purposes. For instance, they may address compliance or transparency issues but do not have the same direct impact on the negotiation process as the Truth in Negotiations Act does.
