(1) A function of the Department of Defense performed by 10 or more Department of Defense civilian employees may not be converted, in whole or in part, to performance by a contractor unless the conversion is based on the results of a public-private competition that
(A) formally compares the cost of performance of the function by Department of Defense civilian employees with the cost of performance by a contractor;
(B) creates an agency tender, including a most efficient organization plan, in accordance with Office of Management and Budget Circular A76, as implemented on May 29, 2003, or any successor circular;
(C) includes the issuance of a solicitation;
(D) determines whether the submitted offers meet the needs of the Department of Defense with respect to factors other than cost, including quality, reliability, and timeliness;
(E) examines the cost of performance of the function by Department of Defense civilian employees and the cost of performance of the function by one or more contractors to demonstrate whether converting to performance by a contractor will result in savings to the Government over the life of the contract, including
(i) the estimated cost to the Government (based on offers received) for performance of the function by a contractor;
(ii) the estimated cost to the Government for performance of the function by Department of Defense civilian employees; and
(iii) an estimate of all other costs and expenditures that the Government would incur because of the award of such a contract;
(F) requires continued performance of the function by Department of Defense civilian employees unless the difference in the cost of performance of the function by a contractor compared to the cost of performance of the function by Department of Defense civilian employees would, over all performance periods required by the solicitation, be equal to or exceed the lesser of
(i) 10 percent of the personnel-related costs for performance of that function in the agency tender; or
(ii) $10,000,000;
(G) requires that the contractor shall not receive an advantage for a proposal that would reduce costs for the Department of Defense by
(i) not making an employer-sponsored health insurance plan (or payment that could be used in lieu of such a plan), health savings account, or medical savings account available to the workers who are to be employed to perform the function under the contract;
(ii) offering to such workers an employer-sponsored health benefits plan that requires the employer to contribute less towards the premium or subscription share than the amount that is paid by the Department of Defense for health benefits for civilian employees of the Department under chapter
89 of title
5; or
(iii) offering to such workers a retirement benefit that, in any year, costs less than the annual retirement cost factor applicable to civilian employees of the Department of Defense under chapter
84 of title
5; and
(H) examines the effect of performance of the function by a contractor on the military mission associated with the performance of the function.
(3) In no case may a function being performed by Department of Defense personnel be
(A) modified, reorganized, divided, or in any way changed for the purpose of exempting the conversion of the function from the requirements of this section; or
(B) converted to performance by a contractor to circumvent a civilian personnel ceiling.
