Washington, D.C. 20080
Dear Sirs/Madams:
At your request, we have read the description included in your Quarterly Report on Form 10-Q to the
Securities and Exchange Commission for the quarter ended December 31, 2017, of the facts relating to
the change in methodology of accounting for natural gas, propane, and odorant, inventory balances from
the First-in First-out (“FIFO”) method to the average cost method under which the cost of units carried in
inventory is based on the weighted average cost per unit of inventory. We believe, on the basis of the
facts so set forth and other information furnished to us by appropriate officials of Washington Gas Light
Company, that the accounting change described in your Form 10-Q is to an alternative accounting
principle that is preferable under the circumstances.
We have not audited any condensed financial statements of Washington Gas Light Company (the
“Company”) as of any date or for any period subsequent to September 30, 2017. Therefore, we are unable
to express, and we do not express, an opinion on the facts set forth in the above-mentioned Form 10-Q, on
the related information furnished to us by officials of the Company, or on the condensed balance sheets,
condensed statements of income, or cash flows of the Company as of any date or for any period
subsequent to September 30, 2017.
Yours truly,
