measures. In addition to the GAAP presentations of net earnings, Berkshire shows operating earnings defined as net earnings exclusive of investment gains (losses), impairments of goodwill and intangible assets and other-than-temporary impairments of
equity method investments. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Although the investment of insurance and reinsurance premiums to generate investment income and investment gains or losses is
an integral part of Berkshire&#8217;s operations, the generation of investment gains or losses is independent of the insurance underwriting process. Moreover, as previously described, under applicable GAAP accounting requirements, we are required to
include the changes in unrealized gains/losses of our equity security investments as a component of investment gains/losses in our periodic earnings statements. In sum, investment gains/losses for any particular period are not indicative of
quarterly business performance. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>About Berkshire </B></P>
