The accounting policies that reflect our more significant estimates and judgments and that we believe are the most critical to aid in fully understanding and evaluating our reported financial results are revenue recognition, including percentage-of-completion accounting for oil & gas projects; allowance for doubtful accounts; allowance for product warranty; valuation of stock options; valuation and impairment of goodwill and acquired intangible assets; useful lives for depreciation and amortization; valuation adjustments for excess and obsolete inventory; deferred taxes and valuation allowances on deferred tax assets; and evaluation and measurement of contingencies, including contingent consideration. Those estimates could change, and as a result, actual results could differ materially from those estimates. For example, the Company records impairment losses on long-lived assets used in operations when events and circumstances indicate that long-lived assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amounts of those assets. The Company’s estimate of undiscounted cash flows, at <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"> December</div> <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">31,</div> <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">2016</div> and <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">2015</div> indicated that such carrying amounts were expected to be recovered. Nonetheless, it is possible that the estimate of undiscounted cash flows <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"> may</div> change in the future resulting in the need to write down those assets to fair value.</div></div></div></div></div></div></div></div></div>
