is Ontario&#146;s largest electricity transmission and distribution provider with more than 1.3&nbsp;million customers, C$24.8&nbsp;billion in assets and revenues of over C$6.5&nbsp;billion. Their team of 5,500 skilled and dedicated employees
proudly and safely serves suburban, rural and remote communities across Ontario through our 18,641 mile high-voltage transmission and 76,429 mile distribution networks. Hydro One is committed to the communities it serves, and has been rated as the
top utility in Canada for its corporate citizenship, sustainability, and diversity initiatives, and is one of only four utility companies in Canada to achieve the Sustainable Energy Company designation from the Canadian Electrical
Association.&nbsp;It also provides advanced broadband data and telecommunications services on a wholesale basis utilizing its extensive fiber optic network. Hydro One&#146;s common shares are listed on the Toronto Stock Exchange (TSX: H). </I></P>

Canadian companies acquired utilities in the U.S., following several acquisitions by some of the same Canadian companies in previous years. These acquisitions were approved by federal and state regulators. </I></P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman"><I>No. Hydro One was a Crown Corporation, owned by the Provincial government, until the company was privatized in an initial public stock
offering in 2015. The privatization of Hydro One was conducted under an agreement between the company and the Provincial government. That Governance Agreement states that the Province will &#147;engage in the business and affairs&#148; of Hydro One
and its subsidiaries &#147;as an investor and not as a manager.&#148; While the Province will remain Hydro One largest shareholder, its nominees to the Board of Directors must be independent of the government and the Province presently owns less
than 50% of the shares in Hydro One. The governance structure under which Hydro One will hold Avista as a subsidiary will also function to preserve Avista&#146;s operational independence. It&#146;s worth noting that three Canadian government pension
funds are minority owners in Puget Sound Energy; having Canadian government-related involvement in the ownership of utilities is not unusual. </I></P>
