The Company bases its estimates on historical experience and various other factors believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are <em style="font: inherit;">not</em> readily apparent from other sources. On an ongoing basis, the Company evaluates its estimates, including those related to revenue recognition, collectability of receivables, realizability of inventory, goodwill and intangible assets, contingent consideration, warranty provisions, stock-based compensation, tax reserves, and deferred tax assets. Provisions for depreciation are based on their estimated useful lives using the straight-line method. Some of these estimates can be subjective and complex and, consequently, actual results <em style="font: inherit;"> may </em>differ from these estimates under different assumptions or conditions. While for any given estimate or assumption made by the Company’s management there <em style="font: inherit;"> may </em>be other estimates or assumptions that are reasonable, the Company believes that, given the current facts and circumstances, it is unlikely that applying any such other reasonable estimate or assumption would materially impact the financial statements.</p> <p style="font-family: "Times New Roman"; font-size: 10pt; margin: 0pt; text-align: justify;"> </p> <p style="font-family: "Times New Roman"; font-size: 10pt; margin: 0pt 0pt 0pt 9pt; text-align: left;"/>
