Some authorities object to the verb sense of impact, meaning "to influence; to affect; to have an impact on" or "to collide or strike". Although most verbification instances in English draw no prescriptive attention, a few do, including this one. To avoid annoying those readers who care, one can replace the verb sense with affect, which nearly always produces an acceptable result. See also the usage note for the noun sense.
