In applying these estimates and assumptions, management makes subjective and complex judgments that frequently require assumptions about matters that are uncertain and inherently subject to change. Actual results could differ from these estimates and assumptions. Included among the material (or potentially material) reported amounts and disclosures that require use of estimates are: fair value of certain financial assets, derivatives, allowances for credit losses, goodwill and other intangibles, MRBs, future contract benefits, income taxes including the recoverability of our deferred tax assets, and the potential effects of resolving litigated matters.</span></div>
