The Company’s most significant estimates relate to medical costs payable, revenues, and goodwill and other intangible assets. Certain of these estimates require the application of complex assumptions and judgments, often because they involve matters that are inherently uncertain and will likely change in subsequent periods. The impact of any change in estimates is included in earnings in the period in which the estimate is adjusted.</font></div></div>
