Non - GAAP financial measures have inherent limitations . Readers should be aware of these limitations and should be cautious with respect to the use of such measures . To compensate for these limitations, we use non - GAAP financial measures as comparative tools, together with GAAP financial measures, to assist in the evaluation of our operating performance or financial condition . Also, we ensure that these measures are calculated using the appropriate GAAP or regulatory components in their entirety and that they are computed in a manner intended to facilitate consistent period - to - period comparisons . ChoiceOne’s method of calculating these non - GAAP financial measures may differ from methods used by other companies . These non - GAAP financial measures should not be considered in isolation or as a substitute for those financial measures prepared in accordance with GAAP or applicable regulatory requirements . Where non - GAAP financial measures are used, the most directly comparable GAAP or regulatory financial measure, as well as the reconciliation to the most directly comparable GAAP or regulatory financial measure, can be found in this presentation .
