Natural estimates the total liability for tax reform benefits allocated to Washington customers to be approximately $20.2&nbsp;million related to TCJA, which is comprised of a historical deferred liability of $18.1&nbsp;million primarily related to
property, plant, and equipment and an expected $2.1&nbsp;million associated with interim tax benefits accumulating from January&nbsp;1, 2018 to November&nbsp;30, 2019. NW Natural is requesting that the $18.1&nbsp;million historical deferral be
credited to rates in compliance with TCJA guidance, which is currently at a rate of approximately $0.5&nbsp;million annually for the first five years, and which would be reviewed and adjusted in year five for the next five years. NW Natural is
requesting that the interim $2.1&nbsp;million tax benefit be returned to customers over two years. </P>

allow the utility to continue encouraging customers to conserve energy without adversely affecting earnings due to reductions in sales volumes. The proposed decoupling tariff would also adjust for any deviation from normal usage, including weather.
</P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Finally, NW Natural is requesting that the WUTC review costs allocable to Washington that have been incurred related to environmental remediation
expenses and consider a mechanism for the recovery of these costs. The requested costs are estimated to be approximately 3.32% of total costs associated with those sites related to serving Washington customers. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">NW Natural&#146;s filing will be reviewed by the WUTC and other stakeholders. The process is anticipated to take up to 11 months. NW Natural has requested

Item 7.01 Regulation FD Disclosure.
On January 2, 2019, Northwest Natural Gas Company (NW Natural), a wholly owned subsidiary of Northwest Natural Holding Company (NW Holdings) announced
that NW Natural filed for a general rate case with the Washington Utilities and Transportation Commission.
A copy of the press release announcing this
order is attached as Exhibit 99.1.
The information contained in this Item 7.01 and in the accompanying exhibit shall not be incorporated by reference
into any filing of NW Holdings and NW Natural, whether made before or after the date hereof, regardless of any general incorporation language in such filing, unless expressly incorporated by specific reference to such filing. The information in this
Item 7.01, including the exhibit hereto, shall not be deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section or Sections 11 and 12(a)(2) of
the Securities Act of 1933, as amended.
Item 8.01 Other Events.
On December 31, 2018, Northwest Natural Gas Company (NW Natural), a subsidiary of Northwest Natural Holding Company (NW Holdings), filed a request for a
general rate increase with the Washington Utilities and Transportation Commission (WUTC). Approximately 84,000 or 11% of NW Natural's customers are in, and approximately 10% of NW Natural's revenues are derived from, Washington. The
remainder of customers and revenues are in Oregon.
This is NW Natural's first Washington rate case in a decade and includes a requested base rate
increase of 12.6% or an $8.3 million increase in annual revenue requirement before accounting for the effects of returning federal tax reform benefits to customers. The requested increase is intended to recover operating costs and investments
made in the Washington distribution system and is based upon the following assumptions or requests:
•
Capital structure of 49.5% long-term debt, 1.0% short-term debt, and 49.5% common equity;
•
Return on equity of 10.3%;
•
Cost of capital of 7.63%; and
•
Rate base of $186.5 million, an increase of $58.7 million since the last rate case.
The filing also includes a proposal to return federal tax reform benefits to customers related to the Tax Cuts and Jobs Act (TCJA). NW
Natural estimates the total liability for tax reform benefits allocated to Washington customers to be approximately $20.2 million related to TCJA, which is comprised of a historical deferred liability of $18.1 million primarily related to
property, plant, and equipment and an expected $2.1 million associated with interim tax benefits accumulating from January 1, 2018 to November 30, 2019. NW Natural is requesting that the $18.1 million historical deferral be
credited to rates in compliance with TCJA guidance, which is currently at a rate of approximately $0.5 million annually for the first five years, and which would be reviewed and adjusted in year five for the next five years. NW Natural is
requesting that the interim $2.1 million tax benefit be returned to customers over two years.
2
In addition, NW Natural is requesting a decoupling tariff for Washington customers, which is intended to
allow the utility to continue encouraging customers to conserve energy without adversely affecting earnings due to reductions in sales volumes. The proposed decoupling tariff would also adjust for any deviation from normal usage, including weather.
Finally, NW Natural is requesting that the WUTC review costs allocable to Washington that have been incurred related to environmental remediation
expenses and consider a mechanism for the recovery of these costs. The requested costs are estimated to be approximately 3.32% of total costs associated with those sites related to serving Washington customers.
NW Natural's filing will be reviewed by the WUTC and other stakeholders. The process is anticipated to take up to 11 months. NW Natural has requested
that the new rates take effect December 1, 2019.

This report, and other presentations made by NW Holdings and NW Natural from time to time, may contain forward-looking statements within the meaning of the

other statements that are other than statements of historical facts.
Forward-looking statements are based on our current expectations and assumptions

All forward-looking statements made in this report and all subsequent forward-looking statements, whether
written or oral and whether made by or on behalf of NW Natural or NW Holdings, are expressly qualified by these cautionary statements. Any forward-looking statement speaks only as of the date on which such statement is made, and we undertake no
obligation to publicly update any forward-looking statement, whether as a result of new information, future developments or otherwise, except as may be required by law.
New factors emerge from time to time and it is not possible for the company to predict all such factors, nor can it assess the impact of each such factor or
the extent to which any factor, or combination of factors, may cause results to differ materially from those contained in any forward-looking statements.
