Title 48

SECTION 9904.407-50

9904.407-50 Techniques for application.

(a)(1) A contractor's written statement of practices with respect to standards shall include the bases and criteria (such as engineering studies, experience, or other supporting data) used in setting and revising standards; the period during which standards are to remain effective; the level (such as ideal or realistic) at which material-quantity standards and labor-time standards are set; and conditions (such as those expected to prevail at the beginning of a period) which material-price standards and labor-rate standards are designed to reflect.

(2) Where only either the material price or material quantity is set at standard, with the other component stated at actual, the result of the multiplication shall be treated as material cost at standard. Similarly, where only either the labor rate or labor time is set at standard, with the other component stated at actual, the result of the multiplication shall be treated as labor cost at standard.

(3) A labor-rate standard may be set to cover a category of direct labor only if the functions performed within that category are not materially disparate and the employees involved are interchangeable with respect to the functions performed.

(4) A labor-rate standard may be set to cover a group of direct labor workers who perform disparate functions only under either one of the following conditions:

(i) Where that group of workers all work in a single production unit yielding homogeneous outputs (in this case, the same labor-rate standard shall be applied to each worker in that group).

(ii) Where that group of workers, in the performance of their respective functions, forms an integral team (in this case, a labor-rate standard shall be set for each integral team).

(b)(1) Material-price standards may be used and their related variances may be recognized either at the time purchases of material are entered into the books of account, or at the time material cost is allocated to production units.

(2) Where material-price standards are used and related variances are recognized at the time purchases of material are entered into the books of account, they shall be accumulated separately by homogeneous groupings of material. Examples of homogeneous groupings of material are:

(i) Where prices of all items in that grouping of material are expected to fluctuate in the same direction and at substantially the same rate, or

(ii) Where items in that grouping of material are held for use in a single production unit yielding homogeneous outputs.

(3) Where material-price variances are recognized at the time purchases of material are entered into the books of account, variances of each homogeneous grouping of material shall be allocated (except as provided in paragraph (b)(4) of this subsection), at least annually, to items in purchased-items inventory and to production units receiving items from that homogeneous grouping of material, in accordance with either one of the following practices, which shall be consistently followed:

(i) Items in purchased-items inventory of a homogeneous grouping of material are adjusted from standard cost to actual cost; the balance of the material-price variance, after reflecting these adjustments, shall be allocated to production units on the basis of the total of standard cost of material received from that homogeneous grouping of material by each of the production units; or

(ii) Items, at standard cost, in purchased-items inventory of a homogeneous grouping of material, are treated, collectively, as a production unit; the material-price variance shall be allocated to production units on the basis of standard cost of material received from that homogeneous grouping of material by each of the production units.

(4) Where material-price variances are recognized at the time purchases of material are entered into the books of account, variances of each homogeneous grouping of material which are insignificant may be included in appropriate indirect cost pools for allocation to applicable cost objectives.

(5) Where a material-price variance is allocated to a production unit in accordance with paragraph (b)(3) of this subsection, it may be combined with material-quantity variance into one material-cost variance for that production unit. A separate material-cost variance shall be accumulated for each production unit.

(6) Where material-price variances are recognized at the time material cost is allocated to production units, these variances and material-quantity variances may be combined into one material-cost variance account.

(c) Labor-cost variances shall be recognized at the time labor cost is introduced into production units. Labor-rate variances and labor-time variances may be combined into one labor-cost variance account. A separate labor-cost variance shall be accumulated for each production unit.

(d) A contractor's established practice with respect to the disposition of variances accumulated by production unit shall be in accordance with one of the following subparagraphs:

(1) Variances are allocated to cost objectives (including ending in-process inventory) at least annually. Where a variance related to material is allocated, the allocation shall be on the basis of the material cost at standard, or, where outputs are homogeneous, on the basis of units of output. Similarly, where a variance related to labor is allocated, the allocation shall be on the basis of the labor cost at standard or labor hours at standard or, where outputs are homogeneous, on the basis of units of output; or

(2) Variances which are immaterial may be included in appropriate indirect cost pools for allocation to applicable cost objectives.

(e) Where variances applicable to covered contracts are allocated by memorandum worksheet adjustments rather than in the books of account, the bases used for adjustment shall be in accordance with those stated in paragraph (b)(3) and paragraph (d) of this subsection.
