<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in">The deferred acquisition consideration
liabilities and redeemable noncontrolling interests are impacted by (i) present value adjustments to accrete the acquisition date
fair value to the estimated future payment amount at the reporting date and (ii) changes in the estimated future payment amount
resulting from the underlying subsidiary&rsquo;s financial performance. Significant changes in financial performance and metrics,
such as profit margins and the rate of earnings growth, relative to expectations could result in adjustments to redemption value.
In addition, the deferred acquisition consideration liabilities and redeemable noncontrolling interests could be materially impacted
by future acquisitions, including acquisitions of incremental ownership of the Company&rsquo;s majority-owned subsidiaries, and
the particular structure of such acquisitions.<FONT STYLE="background-color: white"> These factors and activities are consistent

a discounted cash flow method (an income approach) to estimate the fair value of each of its reporting units representing the price
that would be received for the reporting unit assuming it is sold in an orderly transaction between market participants. In applying
the discounted cash flow method, estimates of future cash flows of each reporting unit are developed using the average of multiple
estimated long-term revenue growth rates and other assumptions (for example, operating margin, EBITDA, tax rates, capital expenditures,
and expected long-term cash flow growth rates) to produce estimates that incorporate a spectrum of possible cash flows of each
reporting unit from a market participant perspective. These estimates of future cash flows are discounted by a WACC that is benchmarked
against the average returns on debt and equity of comparable peer companies (market participants). In the Company&rsquo;s judgment,
this WACC represents an expected rate of return that would be required by a market participant investor in its reporting units,
each of which is used in combination with the other reporting units included within the partner firm network.</P>
