The Patterson Accounting Firm (PAF) does not wish to have its integrity or objectivity compromised by the fact that its tax client, Borovia Corporation, is a constant giver of gifts and entertainment to its outside consulting, law, and accounting firms. Which of the following should PAF keep in mind? a. As long as the gifts are given by Borovia's owners, but not Borovia itself, no objectivity problems arise. b. PAF's accountants should remember that a violation of the integrity duty is presumed if they receive gifts that violate PAF's rules and the member knows or is reckless in not knowing of the violation. c. Gifts that a jury would find "reasonable in the circumstances" are fine even if they violate Borovia's official policy. d. Gifts of entertainment are treated differently for these purposes than gifts of objects or money.
