Fitch Ratings has affirmed the ratings of Berkshire Hathaway Energy
Company (BHE) and certain of its subsidiaries. The Rating Outlook for
BHE is Stable.
Additionally, Fitch has upgraded PacifiCorp's (PPW's) Issuer Default
Rating (IDR) to 'A-' from 'BBB+' and its securities ratings one notch as
indicated at the end of this release. The Rating Outlook for PPW is
Stable. The upgrade reflects PPW's solid underlying credit metrics,
balanced regulation, competitive rates, and manageable capex.
Fitch has affirmed the IDR and securities ratings for the following BHE
subsidiaries: MidAmerican Funding LLC (MF), MidAmerican Energy Co.
(MEC), NV Energy, Inc. (NVE), Nevada Power Co. (NPC), Sierra Pacific
Power Company (SPPC), Northern Natural Gas Company (NNG) and Kern River
Funding Corp. (KRF). The Rating Outlook for these BHE subsidiaries is
Stable.
A complete list of rating actions follows at the end of this release.
KEY RATING DRIVERS
--Ownership of BHE by Berkshire Hathaway, Inc. (BRK; IDR 'AA-'/Outlook
Stable) and enhanced group funding and capital retention capabilities;
--Strong, parent-only cash generation;
--Diverse utility and utility-like, low-risk businesses provide strong,
predictable earnings and cash flows;
--Constructive regulatory compacts across BHE's asset base with balanced
general rate case outcomes.
BHE Ownership:
The ratings consider the favorable impact of BRK's 90% ownership of BHE
by BRK. Ownership of BHE by BRK affords the former with the ability to
retain capital typically paid out in the form of dividends by publicly
held investor-owned-utilities (IOUs). This dynamic is a function of
BRK's strong credit profile, large cash position ($56.2 billion as of
Sept. 30, 2015) and investment appetite. As a result, Fitch estimates
that BHE will be free cash flow (FCF) positive and that consolidated
debt will decline 2015-2019. Other benefits include BRK's ability to
utilize tax shields and fund strategic growth opportunities.
Diversified, Regulated Asset Base:
BHE's ratings are supported by its large high-quality portfolio of
utility and utility-like assets primarily located in the U.S., Canada
and Great Britain. BHE owns three large integrated electric utilities
with generally constructive regulatory compacts and moderately above
industry average growth trends, operating in the U.S. Rocky
Mountain/Pacific Northwest, Midwest and Desert Southwest regions.
Consolidated BHE leverage is high. However, future cash flows from BHE's
diverse portfolio of businesses are projected by Fitch to amply cover
its estimated parent-only obligations.
M&A: BHE has been an active consolidator in the utility, power and gas
sector, acquiring high quality, low-risk electric and gas utility,
electric transmission and natural gas pipeline assets. Large
acquisitions in recent years include AltaLink, L.P. in 2014 and NVE (IDR
'BBB-'; Stable Outlook) in 2013. The impact of M&A on BHE's credit
quality will be driven by price, asset quality and funding choices. Debt
funded acquisitions and/or acquisition of high risk profile businesses
could challenge future credit quality.
Consolidated Financial Metrics: The recent acceleration of BHE M&A
activity and associated increase in parent-company leverage is estimated
by Fitch Ratings to pressure BHE's consolidated credit metrics. Fitch
projects BHE funds from operations (FFO) coverage and leverage ratios
will range from 3.8x to 4.3x and 5.0x to 4.5x, respectively, during
2015-2019.
PPW Upgrade & Stable Outlook:
PPW's ratings and Stable Rating Outlook reflect PPW's strong credit
metrics, balanced jurisdictional regulatory environment and meaningfully
lower estimated 2015-2019 capex compared to historic levels. PPW's
business risk is relatively low and retail rates below the industry
average.
Fitch forecasts FFO coverage and leverage ratios will approximate 5.0x
and 3.8x or better, respectively, consistent with target medians for the
'A-' IDR.
Regulatory Overview: The utility's multi-state service territory and
diversified regulatory environment support the ratings and Rating
Outlook Stable. PPW operates in six states: Utah, Wyoming, Idaho,
Oregon, Washington and California.
Regulatory outcomes across PPW's service territory have been and are
expected to continue to be balanced with the notable exception of
Washington. Various riders are in place to facilitate recovery of
certain costs outside of general rate cases (GRC), including fuel
adjustment clauses that mitigate commodity price exposure in all of
PPW's regulatory jurisdictions.
PPW filed a GRC with the Wyoming Public Service Commission (WPSC) in
March 2015 and currently supports a $27 million (4%) rate increase. The
requested rate hike is based on a 9.85% authorized return on equity
(ROE), 51.4% equity ratio and a test year ending Dec. 31, 2016. A final
order in the GRC is expected later this year. In its previous Wyoming
rate case, the WPSC granted PPW a $20.2 million rate increase based on a
below-industry-average 9.5% authorized ROE. The December 2014 WPSC
authorized rate increase represented approximately 62% of the company
supported $32.6 million rate increase rate increase request.
In Fitch's opinion, WPSC rate orders have been supportive from a
creditworthiness point-of-view, providing the company with a reasonable
opportunity to earn its authorized ROE, notwithstanding the
below-industry-average ROE adopted by the commission in PPW's previous
GRC.
Washington Utilities and Transportation Commission (WUTC) rulings in PPW
GRCs issued in March 2015 and December 2013 were notably unfavorable for
investors. The WUTC orders disallowed costs related to purchased power
from qualifying facilities located outside the state of Washington and
authorized a below-industry-average 9.5% ROE. In its March 2015 order,
the WUTC authorized a rate increase of $9.6 million, 32% of the $30.4
million requested by PPW in the proceeding. In its December 2013 order,
the WUTC approved a $17 million rate increase, approximately 46% of
PPW's requested $37 million rate hike. PPW has appealed both WUTC
orders. Fitch notes that the WUTC earlier this year approved an
all-party stipulation in which the parties agreed to the implementation
of a power cost adjustment mechanism, which includes dead bands and
sharing of deferred balances between the utility and ratepayers.
Manageable Capex: PPW's annual capex was essentially flat in 2014 and
2013 at $1.065 billion and $1.066 billion, respectively, 21% below 2012
capex of $1.346 billion. Capex averaged $1.5 billion per year in
2010-2012. Projected 2015-2017 capex approximates $842 million per year
on average, more than 40% below PPW's $1.5 billion 2010-2012 capex.
Meaningfully lower projected PPW capex reflects completion of large
capital projects, including major transmission, natural gas generation
and renewables investment in the past several years. In addition, capex
incorporates slower PPW service territory load growth and efforts by
management to minimize customer rate increases.
Slowing PPW service territory load growth trends are driven primarily,
in Fitch's view, by energy efficiency gains and are a source of some
uncertainty along with the impact of environmental rules and regulations
on PPW's coal-fired generation.
Fitch believes these dynamics are manageable within the regulatory
compact and unlikely to meaningfully weaken PPW's creditworthiness in
the near to intermediate term. Lower capex is likely to slow the pace of
regulatory filings, easing upward pressure on rates.
Efforts by management to minimize customer rate increases while
maintaining system reliability, safety and customer service have
resulted in generally flat O&M expense.
MF/MEC Ratings Affirmed: The ratings affirmations are based on the
credit quality of MEC, an integrated regulated electric utility. MF is
an intermediate holding company owned by BHE. MF in turn owns MEC and is
dependent on distributions from the utility to meet its ongoing
obligations.
MF and MEC's ratings and their respective Stable Rating Outlooks reflect
the utility's relatively low business risk profile, solid financial
metrics, more diversified fuel-mix in recent years and a balanced
regulatory environment in Iowa.
Constructive Iowa Regulatory Compact: MF and MEC's ratings consider the
constructive outcome in MEC's last rate case filing. In that proceeding,
the Iowa Utilities Board (IUB) increased MEC's base rates $266 million
consistent with the company's requested rate increase. The base rate
increase will be phased in through Jan. 1, 2016.
In addition, the approved MEC settlement authorized energy and
transmission cost adjustment mechanisms. The IUB's order includes
revenue sharing based on specific ROE hurdles.
In recent years, MEC has significantly diversified its fuel-mix via
meaningful new build wind generation while maintaining rates that are
competitive regionally and compared to the national average. This
combined with fuel switching and coal plant retirements should position
MEC well for compliance with EPA regulations, including the agency's
Clean Power Plan.
Solid Credit Metrics: Fitch estimates that MF and MEC's financial
metrics will remain consistent with Fitch's target medians and peers.
MF's FFO coverage and leverage ratios are expected to range between
5.3x-7.1x and 3.8x-3.5x, respectively through 2019. The same metrics for
MEC are forecast to range between 5.8x-6.9x and 3.6x-3.2x, respectively,
over the five-year forecast period.
NVE & Subs Affirmed: The ratings and Rating Outlooks Stable for NVE, NPC
and SPPC reflect solid credit metrics that are consistent with target
medians. The ratings and outlooks also consider the balanced Nevada
regulatory compact, manageable leverage, slowly improving regional
market conditions and modest sales growth.
Favorable Nevada Regulation: Under Nevada regulation, GRC filings are
required at least every three years with a decision required within
seven months from the filing date and adjustments for known and
measurable adjustments to the test year; pre-approval of capex; and,
timely fuel and purchase power cost recovery mechanisms.
In October 2014, the PUC adopted a modified settlement in NPC's 2014
GRC. NPC filed the GRC with the PUC May 2014 requesting a $20.8 million
rate increase based on a 10% ROE. The PUC-approved settlement authorized
no change in base rates and modest rate design changes. In Fitch's view,
the settlement is credit neutral. SPPC and NPC are scheduled to file
triennial rate cases in June 2016 and June 2017, respectively.
Fitch projects NVE FFO coverage and leverage 2015-2019 of 3.8x-4.7x and
4.9x-3.9x, respectively, levels consistent with NVE's 'BBB-' IDR and
operating subsidiaries NVP and SPPC's 'BBB' IDRs.
NNG Ratings Affirmed: The ratings and Rating Outlook Stable for NNG
reflect the pipeline's strong business position and relatively low
business risk profile. NNG's natural gas transportation system is an
essential source of contracted supply to its Upper Midwest utility
customer base.
Counter-party credit risk is ameliorated by the pipeline's diverse group
of primarily highly rated off-takers with multi-year contracts. NNG's
ratings also consider the pipeline operator's constructive regulatory
compact and its consistent ability to earn reasonable returns on equity,
typically in the low double digits.
Fitch projects NNG FFO coverage and leverage 2015-2019 of 5.3x-8.2x and
3.5x-2.2x, respectively, levels consistent with NNG's 'A' IDR.
KRF Ratings Affirmed: The ratings consider KRF's relatively predictable
earnings and cash flows, competitive rates, attractive markets, recent
success in extending maturing shipper contracts and a balanced FERC
regulatory compact. The ratings also consider the pipeline's manageable
projected capex, declining debt and improving credit metrics from an
already strong base.
The KRF pipeline transports competitive Rocky Mountain natural gas to
large volume end-users in Utah, Southern Nevada and Southern California.
KRF coverage and leverage ratios 2015-2019 strongly support its 'A'
rating and Stable Rating Outlook. KRF's outstanding debt is expected by
Fitch to fully amortize by 2018 with no expectation for issuance of any
additional debt.
Re-contracting and more stringent rules regarding pipeline integrity and
related issues are potential sources of concern for both NNG and KRF.
Fitch believes these concerns are manageable within the pipelines'
current rating categories given their strong competitive positions in
their respective markets and ongoing infrastructure investment by
management.
KEY ASSUMPTIONS
Fitch's key assumptions within the rating case for BHE and its
subsidiaries include:
--Estimated 2016-2019 parent-only FCF of $7 billion-$8 billion;
--Repayment of trust preferred issued to fund recent acquisitions by the
end of 2016;
--Reasonable outcomes in pending and future operating utility rate case
outcomes;
--No meaningful deterioration in key U.S. regulatory jurisdictions;
--Earned returns on equity of better than 10% at MEC and 9%-10% at PPW
and NVE;
RATING SENSITIVITIES
Positive: Future developments that may individually or collectively lead
to positive credit rating actions for BHE and its subsidiaries include
the following.
--BHE: High consolidated leverage limits positive rating actions in the
near-to-intermediate term. Nonetheless, improvement in FFO-adjusted
leverage to 3.6x-3.8x or better on a sustained basis could result in
future credit rating upgrades.
--MF: Structural subordination of MF debt to MEC and current notching
requires an upgrade at the utility to accommodate an MF upgrade.
--MEC: The utility's strong credit rating and parent - subsidiary
notching considerations limit positive rating actions. However, stable,
sustained FFO adjusted coverage and leverage ratios of 5.0x and 3.5x,
respectively, or better, could result in future credit rating upgrades.
--PPW: Further positive rating actions for PPW are unlikely in the
near-to-intermediate term given the recent upgrade and other
considerations. However, further improvement in PPW's FFO coverage and
leverage ratios to 5.0x and 3.5x, respectively, in concert with a stable
or improving business risk profile could result in future upgrades.
--NVE/NPC/SPPC: Improvement in NVE's FFO and EBITDAR leverage to better
than 5.0x and 3.75x, respectively, on a long-term projected basis could
lead to a one-notch upgrade for NVE and its operating subsidiaries, NPC
and SPPC.
--NNG and KRF: The pipelines' relatively high ratings challenge future
positive rating actions.
Future developments that may, individually or collectively, lead to
credit rating downgrades include:
--BHE: Deterioration of BHE's FFO adjusted leverage to 5.0x-5.5x or
worse on a consistent basis would likely lead to future credit
downgrades.
Longer term, a change in ownership structure and/or strategic direction
at BRK eliminating or diminishing capital retention and other benefits
currently available to BHE would likely lead to future downgrades at the
utility holding company and pressure its subsidiaries' ratings as well.
Large debt funded M&A transactions and/or acquisition of assets with
more volatile cash flows and higher business risk could trigger future
credit rating downgrades.
--MF and MEC: A significant deterioration in the regulatory compact in
Iowa or other factors causing MEC's FFO leverage weaken to 4.5x or worse
on a sustained basis would likely lead to credit rating downgrades for
both MEC and MF.
--PPW: An unexpected, sustained weakening of FFO leverage due to
deterioration in PPW's regulatory oversight, higher-than-expected capex
or other factors to 4.5x or worse could lead to future credit rating
downgrades.
--NVE/NPC/SPPC: An unexpected deterioration in the currently
constructive regulatory compact in Nevada or other factors pressuring
FFO leverage to 6.0x or weaker for NVE could lead to future, adverse
rating actions for NVE and its subsidiaries, SPPC and NPC.
--NNG: Deterioration of NNG's FFO leverage to 4.0x or weaker could
result in future credit rating downgrades.
--KRF: Given the pipeline's strong operating profile and already low and
amortizing debt, credit rating downgrades appear unlikely at this
juncture.
LIQUIDITY
BHE's liquidity is strong, with total available consolidated liquidity
of $7 billion as of Sept. 30, 2015. Liquidity is composed of BHE's $1.7
billion of consolidated cash on BHE's balance sheet and $5.4 billion of
unused borrowing capacity under its $6.7 billion of committed revolving
credit facilities. BHE has a $2 billion parent-only credit facility that
matures in 2017 and supports its CP program. Debt maturities are
manageable, approximating $1.8 billion 2015-2019 on average per annum.
