RATINGS RATIONALE
"The upgrade of NorthWestern's long-term ratings reflects
our expectation that the company's trend of solid financial performance
is likely to be sustainable over the medium term and beyond, including
financial credit metrics that would be considered strong within the Baa
rating category according to our Rating Methodology for Regulated Electric
and Gas Utilities, published in August 2009" said Vice President-Senior
Analyst, Kevin Rose. The rating upgrades also take into account
a satisfactory outcome in NorthWestern's latest general rate case,
which resulted in an approximate $6.5 million (3%)
electric rate increase and established a four-year pilot revenue
decoupling mechanism for most of the company's electric customers.
"The outcome in this case is yet another sign of credit supportive
treatment by the Montana Public Service Commission (MPSC)" Rose
added.
The assignment of the Prime-2 short-term rating reflects
NorthWestern's proactive approach to maintaining sufficient internal
and external liquidity and the company's sound overall credit quality
as evidenced by its Baa1 long-term rating for senior unsecured
debt.
Several factors have been contributing to NorthWestern's stronger
metrics over the last several years, including debt reduction,
refinancing at lower interest rates, and reasonably supportive regulatory
treatment in its three regulatory jurisdictions. NorthWestern's
cash flow from operations before the effects of working capital changes
(CFO Pre-W/C) to interest and debt averaged over 4x and 20%,
respectively, over the three fiscal years covering 2007 --
2009, and stood at 4.2x and 21.4%, respectively,
for the 12 months ended September 30, 2010. NorthWestern
has also significantly reduced its level of debt as its debt to book capitalization
ratio has fallen from approximately 77% in 2004 to approximately
52.2% at September 30, 2010, including Moody's
standard adjustments. Management continues to target a range of
50% to 55% debt to book capitalization.
NorthWestern is focused on its utility operations, where it plans
to spend about $580 million of maintenance capex over 2011 -
2014, fairly evenly distributed each year. Over this period
we note that the utility capex budget will no longer include additional
amounts for generation construction related to the 150 megawatt natural
gas fired Mill Creek Generation Station, which was placed into commercial
operation on January 1, 2011. The MPSC has approved rate
base treatment for this plant premised on a 10.25% allowed
return on equity and a 50/50 capital structure. Interim rates related
to recovery of and return on this investment became effective with commercial
operations and a true up of those rates will follow upon completion of
a compliance filing to be made by NorthWestern no later than March 31,
2011.
Meanwhile, the pace of progress related to some of NorthWestern's
potential growth investment opportunities in regulated electric transmission
projects has slowed due to assorted issues including siting delays,
economic conditions, and uncertainty about future potential for
federal renewable portfolio standards. Nevertheless, NorthWestern's
management team remains open to pursuing these projects, which include
the potential for three separate transmission projects that could potentially
result in growth capex exceeding $1 billion even if the projects
are pursued in partnership with others. At this level of spending,
NorthWestern would more than double its utility rate base over a multi-year
period. Management emphasizes that such investments can be re-sized
based on market and economic conditions, and will only be made if
market demands make them economically viable and there is reasonable assurance
that regulators will provide timely cost recovery and a reasonable opportunity
to earn a fair return commensurate with the risk undertaken.
To supplement its cash flow from operations, we expect that NorthWestern
will maintain sufficient alternate liquidity for its commercial paper
program through a committed three-year $250 million revolving
bank credit agreement expiring June 30, 2012 and led by Banc of
America Securities LLC. The quality of the alternate liquidity
provided by the $250 million facility is generally good,
taking into account the multi-year term at its inception,
same day availability, no ongoing material adverse change clause,
and the absence of onerous financial covenants. Moreover,
we anticipate that NorthWestern will begin to address renewal and extension
of this facility later this year to ensure completion of the process well
ahead of the expiration date.
The stable rating outlook reflects our view that NorthWestern is well
positioned to continue producing solid financial results in spite of slowly
improving economic conditions to support its Baa1 rating. It also
assumes that NorthWestern continues to receive support from state regulators
and follows conservative financing of growth initiatives that become economically
viable.
NorthWestern's rating can be considered for an upgrade if it continues
to receive regulatory support (especially in Montana) and its financial
profile strengthens beyond current expectations as it carries out its
strategic initiatives; for example, if the company successfully
carries out its contemplated growth initiatives while demonstrating an
ability to generate CFO Pre-W/C plus interest to interest coverage
and CFO Pre-W/C to debt in the mid 4x range and near 25%,
respectively, on a sustainable basis.
A downgrade of NorthWestern's ratings is unlikely in the near to
intermediate term given the expected level of financial performance.
However, an unexpected shift away from the current primary focus
on regulated electric and gas utility operations that involves higher
business risk without a commensurate improvement in financial ratios could
lead to a downgrade. Also, if NorthWestern unexpectedly implements
a more shareholder-friendly dividend policy or uses a significant
amount of debt to finance various utility-related growth opportunities,
then these strategies could cause us to take a negative rating or outlook
action. Specifically with respect to credit metrics, if NorthWestern's
future financial performance causes CFO Pre-W/C plus interest to
interest coverage and CFO Pre-W/C to debt to fall below 4x and
20%, respectively, for an extended period, then
a negative action could result.
The principal methodology used in this rating was Regulated Electric and
Gas Utilities published in August 2009.
NorthWestern Corporation, headquartered in Sioux Falls, South
Dakota, conducts regulated electric and gas utility operations in
Montana, South Dakota, and Nebraska through its NorthWestern
Energy division.
