Is a business record admissible as an exception to the hearsay rule?

" 'Whether a particular business record is admissible as an exception to the hearsay rule . . . depends upon the "trustworthiness" of such evidence, a determination that must be made, case by case, from the circumstances surrounding the making of the record. [Citations.]' " (People v. Matthews (1991) 229 Cal.App.3d 930, 939.) As to authentication, there must "be sufficient evidence for a trier of fact to find that the writing is what it purports to be, i.e., that it is genuine for the purpose offered." (People v. Goldsmith (2014) 59 Cal.4th 258, 267; see Evid. Code, 1400, 1401, subd. (a).)
