Alan C. Kay, J., Metzler Contracting Co. Llc v. Stephens, 774 F.Supp.2d 1073, n. 12 (D. Haw., 2011): "If the contract was a cost-plus-fee contract with no guaranteed maximum, then the arbitrator could plausibly determine that the preliminary budget did not constrain the contract sum. On the other hand, if the contract sum could not exceed the preliminary budget, as amended, then the arbitrator could plausibly determine that the contract did have a guaranteed maximum, despite its express provision that the guaranteed maximum was “N/A.” The former interpretation is consistent with Metzler's contention that “N/A” means “not applicable,” whereas the latter is consistent with the Stephenses' contention that it means “not available,” in that the contract required Metzler to prepare the preliminary budget after the contract was signed".
Franklin D. Elia, J., Santa Clara Cnty. Dep't of Family & Childen's Servs. v. C.K. (Cal. App., 2010): "We are not persuaded by appellants' claim that the January 2008 notice was defective because "N/A" was entered in the space for the tribe or band of the children's maternal great-grandmother Elsie Margaret Hamilton Senna. The record does not establish that the great-grandmother was affiliated with any particular Seneca tribe or band. The abbreviation "N/A" or "N.A." or "NA" can mean "not available" as well as "not applicable".
