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.) "The foundation for admitting the record is properly laid if in the opinion of the court, the sources of information, method, and time of preparation were such as to justify its admission." (People v. Williams (1973) 36 Cal.App.3d 262, 275.)
