immediate family and related entitles (including trusts of which he is trustee), or pursuant to a power of attorney or other trading authorization, additional shares of Common Stock or other DVA securities, without Mr. Buffetts prior

Common Stock. Each of the Insurance Company Holders is a wholly-owned subsidiary of (and controlled by) GEICO Corp. GEICO Corp. is a wholly-owned subsidiary of (and controlled by) NICO. Thus, each of NICO and GEICO Corp may be deemed to have

(the Pension Plan Holders) directly own 20,052,088 shares of Common Stock, which represents 10.5% of the outstanding Common Stock.

Mr. Buffett may be deemed to control Berkshire, which controls NICO. Thus, Mr. Buffett and Berkshire may be deemed to have
beneficial ownership of the Shares.

Mr. Weschler beneficially owns 2,383,180 shares of Common Stock, which represents 1.2% of the
outstanding Common Stock. Mr. Weschler disclaims beneficial ownership of all Insurance Company Shares and Pension Plan Shares.

ended June 30, 2017, which was filed by DVA with the SEC on August 1, 2017.

(b) The Insurance Company Holders have both voting
and investment power with respect to the Insurance Company Shares owned by them and the Pension Plan Holders have both voting and investment power with respect to the Pension Plan Shares owned by them. However, because NICO and GEICO Corp control
the Insurance Company Holders, NICO and GEICO Corp may be deemed to share voting and investment power with respect to the Insurance Company Shares. In addition, Berkshire directs the investments of NICO, GEICO Corp, and the Pension Plan Holders.
Thus, Mr. Buffett, who may be deemed to control Berkshire, and Berkshire share voting power and investment power with respect to the Shares.

Mr. Weschler has sole voting and investment power with respect to 2,239,806 of the Weschler Shares and shared dispositive (but not
investment) power with respect to 143,374 of the Weschler Shares.
