Actual results could differ from those estimates. Significant estimates and judgments include those related to revenue recognition, investments, accounts receivable, inventories, long-lived assets, internal-use software, goodwill, warranty obligations, contingencies, derivative instruments, stock-based compensation, income taxes, and business combinations.</font></div></div>
