(b) Reasonableness—

(1) Compensation pursuant to labor-management agreements. If costs of compensation established under "arm’s length" labor-management agreements negotiated under the terms of the Federal Labor Relations Act or similar state statutes are otherwise allowable, the costs are reasonable unless, as applied to work in performing Government contracts, the costs are unwarranted by the character and circumstances of the work or discriminatory against the Government. The application of the provisions of a labor-management agreement designed to apply to a given set of circumstances and conditions of employment (e.g., work involving extremely hazardous activities or work not requiring recurrent use of overtime) is unwarranted when applied to a Government contract involving significantly different circumstances and conditions of employment (e.g., work involving less hazardous activities or work continually requiring use of overtime). It is discriminatory against the Government if it results in employee compensation (in whatever form or name) in excess of that being paid for similar non-Government work under comparable circumstances.

(2) Compensation not covered by labor-management agreements. Compensation for each employee or job class of employees must be reasonable for the work performed. Compensation is reasonable if the aggregate of each measurable and allowable element sums to a reasonable total. In determining the reasonableness of total compensation, consider only allowable individual elements of compensation. In addition to the provisions of 31.201-3, in testing the reasonableness of compensation for particular employees or job classes of employees, consider factors determined to be relevant by the contracting officer. Factors that may be relevant include, but are not limited to, conformity with compensation practices of other firms—

(i) Of the same size;

(ii) In the same industry;

(iii) In the same geographic area; and

(iv) Engaged in similar non-Government work under comparable circumstances.
