Published by Set-Aside Alert Newsletter: Size and status representations for task orders issued under Multiple Award Contracts (MAC) and schedules have become a controversial and complex issue. Generally, the Small Business Administration’s (SBA) size rules state that representations made at the time of initial offer are valid throughout the life of a contract. This means that all representations made with respect to a MAC will be valid for each order issued against the contract, unless a contracting officer requests recertification in connection with a specific order.
