[The term “cost” as applied to warranty service agreements also includes the cost of parts and delivery of the parts.]

[The term “cost” as applied to distribution also includes either the invoice cost or replacement cost of the product, whichever is lower.]

[The term “cost” as applied to services also includes the prevailing wage at the time and place these services were provided if [name of defendant] was paying less than the prevailing wage.]

Any discounts given for cash payments may not be used to lower costs.

Sources and Authority

“Cost” Defined. Business and Professions Code section 17026.

“Cost of Doing Business” or “Overhead” Defined. Business and Professions Code section 17029.

Prevailing Wage Used to Determine Cost. Business and Professions Code section 17076.

“Determination of the defendant’s cost has always been treated as an issue of fact.” (Pan Asia Venture Capital Corp. v. Hearst Corp. (1999) 74 Cal.App.4th 424, 433 [88 Cal.Rptr.2d 118].)

“These statutes embody California’s fully allocated cost standard, that is, a fair allocation of all fixed or variable costs associated with production of the article or product.” (Pan Asia Venture Capital Corp., supra, 74 Cal.App.4th at p. 432, footnote omitted.)

“Cost is to be measured as ‘the fair average cost of production over a reasonable time, rather than the cost of one item on a particular occasion.’ ” (Pan Asia Venture Capital Corp., supra, 74 Cal.App.4th at p. 432, fn. 6, internal citation omitted.)

“Variable costs are costs that vary with changes in output, while fixed costs are those that do not vary with changes in output.” (Turnbull & Turnbull v. ARA Transportation Inc. (1990) 219 Cal.App.3d 811, 820 [268 Cal.Rptr. 856].)

“California employs a fully allocated cost standard to determine whether a sale has violated section 17043. Under sections 17026 and 17029 … cost means invoice cost plus the vendor’s full cost of doing business or six percent.” (G.H.I.I. v. Mts, Inc. (1983) 147 Cal.App.3d 256, 275 [195 Cal.Rptr. 211], internal citations omitted.)

“We find the use of the fully allocated cost method, when viewed in conjunction with the injurious intent requirement of section 17043, is rationally related to the valid legislative purpose … as it assists in preventing the creation or perpetuation of monopolies.” (Turnbull & Turnbull, supra, 219 Cal.App.3d at p. 822.)

“To be legally acceptable, the allocation of indirect or fixed overhead costs to a particular product or service must be reasonably related to the burden such product or service imposes on the overall cost of doing business.” (Turnbull & Turnbull, supra, 219 Cal.App.3d at p. 822.)
