A UNIQUE TIME IN HISTORY
Otter Tail Corporation operating companies and corporate team 
members stand strong in the face of COVID-19 as we successfully 
navigate supply chain constraints, manage commodity pricing, 
adjust staffing levels, and support increased customer demand. Our 
business continuity and pandemic plans put the health and safety of 
our employees, customers, and communities at the forefront as we 
continue to provide outstanding customer service.

We achieved consolidated net income and diluted earnings per share 
in 2021 of $176.8 million and $4.23, respectively, compared with 
$95.9 million and $2.34 in 2020; earnings per share increased  
80.8 percent year over year. Return on equity was 19.2 percent.

The dividend yield at December 31, 2021, was 2.2 percent. Total 
shareholder return has grown at a compounded annual rate of  
15.3 percent over the past five years. We have paid dividends on 
common stock for 83 years, or 333 consecutive quarters. Our annual 
indicated dividend per share for 2022 is $1.65, a 5.8 percent increase 
over our 2021 dividend rate.

Otter Tail Corporation received Edison Electric Institute’s (EEI) Index 
Award for top performing small-capitalization utility with a total 
shareholder return of 89 percent over the past five years at the EEI 
Financial Conference in November 2021. This award is presented 
annually to EEI member companies that have achieved the highest 
total shareholder return in the large-, mid-, and small-capitalization 
categories. 

Our 2021 financial results highlighted throughout this Annual Report, 
along with the EEI Index Award, demonstrate our commitment 
to delivering above-average returns through operational and 
commercial excellence and growing our businesses. 

UTILITY EXECUTES CAPITAL INVESTMENT PLAN
Otter Tail Power Company grew average rate base by 13.7 percent 
in 2021, primarily through capital investments in energy generation 
and regional transmission projects, and increased earnings by  
8.5 percent.

In May 2021 we retired Hoot Lake Plant, marking the end of 
100 years of coal-fired energy generation at the site. The 
142-megawatt (MW) facility in Fergus Falls, Minnesota, played 
a vital role in the company’s history of generating reliable and 
affordable energy. 

After years of planning and two years of construction and testing, 
our Astoria Station natural gas plant went into service in April. 
This $160 million investment complements our wind generation by 
providing a reliable backstop when the wind is not blowing, and it 
has flexible operating options and low emissions. Astoria Station 
provides 245 MW of dispatchable capacity compared to Hoot Lake 
Plant’s 142 MW—with projected 85 percent less carbon emissions 
from historic Hoot Lake Plant levels.

We continue progress on the development of Hoot Lake Solar, a 
$60 million, 49-MW solar farm, which will be constructed on and 
near the retired Hoot Lake Plant property. The project is expected 
to be completed in 2023 and has received renewable rider eligibility 
approval in Minnesota, allocating 100 percent of the costs and 
benefits of the project to Minnesota customers. The location of Hoot 
Lake Solar offers a unique opportunity to utilize existing Hoot Lake 
transmission rights, substation, and land.  

Otter Tail Power filed its Integrated Resource Plan in September. 
Our preferred plan includes the addition of fuel oil backup capability 
at Astoria Station in South Dakota, the addition of 150 MW 
of solar generation at a location yet to be determined, and the 
commencement of the process to withdraw from our 35 percent 
ownership interest in Coyote Station in North Dakota by December 
31, 2028. Our target is to reduce carbon emissions from our owned 
generation resources approximately 50 percent from 2005 levels 
by 2025 and 97 percent by 2050—while keeping residential rates 
among the lowest in the nation. Otter Tail Power and other Coyote 
Station co-owners continue to prepare for potential outcomes of the 
Regional Haze Rule compliance process. 

In late April the North Dakota Safety Council (NDSC) recognized 
Coyote Station for its incredible safety record with a Workplace 
Safety Merit Award. NDSC awarded the Workplace Safety Merit 
Award to member companies showing an Experience Modification 
Rate below 1 for the year 2020. 

We are enhancing transmission infrastructure by investing 
approximately $35 million to improve reliability and increase 
capacity for customers in our southern service area. We completed 
phase one of this project in February 2020 and finished phase two, a 
43-mile, 115-kilovolt transmission line from Lake Norden to Astoria, 
South Dakota, in August 2021. With the completion of these two 
projects, Otter Tail Power has added more than 50 miles of assets 
that support improved transmission system reliability in our southern 
service area.

We also finalized contracts for the installation of Advanced Metering 
Infrastructure (AMI) as we plan to begin initial deployment 
in late 2022. AMI will enable improved outage response and 
communication, reduce meter reading costs, and support web-based 
customer engagement.

In November 2020 we filed a request with the Minnesota 
Public Utilities Commission (MPUC) to increase general rates 
in Minnesota, our first request since 2016. This November the 
MPUC approved changes to our rates to reflect major shifts in our 
company’s generation fleet. While the MPUC’s decision results in 
substantially unchanged rates, the approval recognizes many cost 
reductions we achieved during the rate review, including lower 
depreciation expenses due to lengthening the useful lives of wind 
generation resources, decreased pension costs associated with 
higher pension fund assets, and an increase in expected wind farm 
tax credits. The MPUC issued its written order in February 2022, 
which included the approval of a return on equity of 9.48 percent on 
a 52.5 percent equity layer, a revenue decoupling mechanism, and 
numerous other items. We expect final rates to be implemented by 
mid-2022. Otter Tail Power’s residential customers will continue to 
have some of the lowest rates in the country.

Thanks to resilient and hard-working employees, Otter Tail Power 
continued its long tradition of operational excellence and delivered 
on a historically significant generation resource shift, while providing 
customers with a safe, reliable, and affordable essential service. 
We will continue to make system investments to meet customers’ 
expectations, manage operating and maintenance costs, transition to 
a cleaner energy future, and improve reliability and safety.

MANUFACTURING PLATFORM FOCUSES ON 
CUSTOMER SERVICE AND BUSINESS GROWTH
Our manufacturing platform remains focused on meeting customer 
needs, driving operating efficiencies, and making key investments to 
grow with our customers despite COVID-related labor shortages and 
supply chain challenges.

Northern Pipe Products and Vinyltech, the PVC pipe manufacturing 
companies that comprise our plastics segment, delivered 
extraordinary results with well-managed operations in a tight pipe 
market. PVC resin shortages driven by continued global demand and 
significant production issues associated with February Gulf Coast 
cold weather and hurricanes resulted in escalating PVC pipe prices. 
Unique conditions in the PVC pipe market are expected to continue 
into early 2022. This year’s land acquisition at Vinyltech will allow 
us opportunity to expand organically over the next five years. The 
plastics segment generated $2.34 of earnings per diluted share in 
2021 compared to $0.67 in 2020. 

BTD, our contract metal fabricator, experienced increased customer 
demand and improved sales, with earnings of $14.7 million, a 
43.5 percent increase from 2020. Despite challenges with 
securing staffing levels to support the increased demand, BTD 
was at its highest-ever employee count at the end of 2021. Steel 
prices remained at historically high levels but lead times improved 
throughout the year. The company continues to experience increased 
customer demand as it maintains excellent quality and on-time 
delivery. 

T.O. Plastics, our plastics thermoforming manufacturer, had a record 
year in horticultural end market sales despite labor shortages and 
wage rate pressures.

EXCEPTIONAL YEAR, EXCITING FUTURE
Our dedicated employees continue to lead with resolve and 
innovation. Otter Tail Corporation will continue to create a strong 
future through growing our businesses and achieving operational, 
commercial, and talent excellence. 

To help achieve that strong future, we’ve outlined actions that 
provide for a more inclusive and diverse organization. We look 
forward to continuing this focus as we lead teams into 2022.

We’re positively positioned for the future. Thank you to our 
employees for your efforts in 2021 and your commitment to 
excellence. And thank you to our customers and shareholders for 
placing your confidence in us.

PART	I

ITEM	1.

BUSINESS

Otter	Tail	Corporation	(OTC)	has	interests	in	diversified	operations	that	include	an	electric	utility	and	manufacturing	and	plastic	pipe	businesses	
with	corporate	offices	located	in	Fergus	Falls,	Minnesota	and	Fargo,	North	Dakota.

We	classify	our	five	operating	companies	into	three	reportable	segments	consistent	with	our	business	strategy	and	management	structure.	The	
following	table	depicts	our	three	segments	and	the	subsidiary	entities	included	within	each	segment:

ELECTRIC	SEGMENT

MANUFACTURING	SEGMENT

PLASTICS	SEGMENT

Otter	Tail	Power	Company	(OTP)

BTD	Manufacturing,	Inc.	(BTD)

Northern	Pipe	Products,	Inc.	(Northern	Pipe)

T.O.	Plastics,	Inc.	(T.O.	Plastics)

Vinyltech	Corporation	(Vinyltech)

Electric	includes	the	generation,	purchase,	transmission,	distribution	and	sale	of	electric	energy	in	western	Minnesota,	eastern	North	Dakota	

and	northeastern	South	Dakota.	OTP,	our	largest	operating	subsidiary	and	primary	business	since	1907,	serves	more	than	133,000	customers	in	
more	than	400	communities	across	a	predominantly	rural	and	agricultural	service	territory.

Manufacturing	consists	of	businesses	in	the	following	manufacturing	activities:	contract	machining;	metal	parts	stamping,	fabrication	and	
painting;	and	production	of	plastic	thermoformed	horticultural	containers,	life	science	and	industrial	packaging,	material	handling	components	and	
extruded	raw	material	stock.	These	businesses	have	manufacturing	facilities	in	Georgia,	Illinois	and	Minnesota	and	sell	products	primarily	in	the	
United	States.

Plastics	consists	of	businesses	producing	polyvinyl	chloride	(PVC)	pipe	at	plants	in	North	Dakota	and	Arizona.	The	PVC	pipe	is	sold	primarily	in	

the	western	half	of	the	United	States	and	Canada.

Throughout	the	remainder	of	this	report,	we	use	the	terms	"Company",	"us",	"our",	or	"we"	to	refer	to	OTC	and	its	subsidiaries	collectively.	We	will	
also	refer	to	our	Electric,	Manufacturing	and	Plastics	segments	and	our	individual	subsidiaries	as	indicated	above.		

INVESTMENT	AND	GROWTH	STRATEGY
We	maintain	a	moderate	risk	profile	by	investing	in	rate	base	growth	opportunities	in	our	Electric	segment	and	organic	growth	opportunities	in	our	
Manufacturing	and	Plastics	segments.	This	strategy	and	risk	profile	are	designed	to	provide	a	more	predictable	earnings	stream,	maintain	our	credit	
quality	and	preserve	our	ability	to	fund	our	dividend	payments.	Our	goal	is	to	deliver	annual	growth	in	earnings	per	share	between	five	and	seven	
percent	over	the	next	several	years,	using	2020	diluted	earnings	per	share	as	the	base	for	measurement.	We	expect	our	earnings	growth	to	come	
from	rate	base	investments	in	our	Electric	segment	and	from	existing	capacities	and	planned	investments	within	our	Manufacturing	and	Plastics	
segments.	

We	will	continue	to	review	our	business	portfolio	to	identify	additional	opportunities	to	improve	our	risk	profile,	enhance	our	credit	metrics	and	
generate	additional	sources	of	cash	to	support	the	organic	growth	opportunities	in	our	electric	utility	and	manufacturing	and	plastics	segments.	We	
will	also	evaluate	opportunities	to	allocate	capital	to	potential	acquisitions	within	our	Manufacturing	and	Plastics	segments.	We	are	a	committed	
long-term	owner	and	do	not	acquire	companies	in	pursuit	of	short-term	gains.	However,	we	will	divest	businesses	which	no	longer	fit	into	our	
strategy	and	risk	profile	over	the	long	term.

We	maintain	a	set	of	criteria	used	in	evaluating	the	strategic	fit	of	our	operating	businesses.	The	operating	company	should:

• Maintain	a	minimum	level	of	net	earnings	and	a	return	on	invested	capital	in	excess	of	the	Company’s	weighted	average	cost	of	capital,

•

•

•

Have	a	strategic	differentiation	from	competitors	and	a	sustainable	cost	advantage,

Operate	within	a	stable	and	growing	industry	and	be	able	to	quickly	adapt	to	changing	economic	cycles,	and

Have	a	strong	management	team	committed	to	operational	and	commercial	excellence.

Over	time,	we	expect	our	Electric	segment	will	provide	approximately	70%	of	our	overall	earnings	and	our	Manufacturing	and	Plastics	segments	will	
collectively	provide	approximately	30%	of	our	overall	earnings	and	continue	to	be	a	fundamental	part	of	our	strategy.

3

Our	actual	mix	of	earnings	for	the	years	ended	December	31,	2021,	2020,	2019	was	as	follows:

Our	2021	earnings	mix	was	impacted	by	significantly	higher	earnings	in	our	Plastics	segment	as	unique	supply	and	demand	conditions	during	the	
year	in	the	PVC	pipe	industry	led	to	earnings	levels	not	previously	experienced.	We	expect	our	earnings	mix	to	return	back	to	our	targeted	mix	of	
70%	from	the	Electric	segment	and	30%	from	the	Manufacturing	and	Plastics	segments	over	the	long	term	as	these	industry	conditions	subside.		

HUMAN	CAPITAL
Our	employees	are	a	critical	resource	and	an	integral	part	of	our	success.	We	strive	to	provide	an	environment	of	opportunity	and	accountability	
where	people	are	valued	and	empowered	to	do	their	best	work.	We	are	focused	on	the	health	and	safety	of	our	employees	and	creating	a	culture	
of	inclusion,	excellence	and	learning.	Our	human	capital	management	efforts	include	monitoring	various	metrics	and	objectives	associated	with	i)	
employee	safety,	ii)	workforce	stability,	iii)	management	and	workforce	demographics,	including	gender,	racial	and	ethnic	diversity,	iv)	leadership	
development	and	succession	planning	and	v)	productivity.	We	have	established	the	following	programs	in	furtherance	of	these	efforts:

Safety	-	Safety	is	one	of	our	core	values.	In	managing	our	business,	we	focus	on	the	safety	of	our	employees	and	have	implemented	safety	
programs	and	management	practices	to	promote	a	culture	of	safety.	Safety	is	also	a	metric	used	and	evaluated	in	determining	annual	incentive	
compensation.	We	continually	monitor	the	Occupational	Safety	and	Health	Administration	(OSHA)	Total	Recordable	Incident	Rate	(number	of	work-
related	injuries	per	100	employees	for	a	one-year	period)	and	Lost	Time	Incident	Rate	(number	of	employees	who	lost	time	due	to	work-related	
injuries	per	100	employees	for	a	one-year	period).	New	cases	are	reported	and	evaluated	for	corrective	action	during	monthly	safety	meetings	
attended	by	safety	professionals	at	all	locations.	Our	2021	Total	Recordable	Incident	Rate	was	1.86,	compared	to	1.42	in	2020	and	our	Lost	Time	
Incident	Rate	was	0.57,	compared	to	0.55	in	2020.	In	both	2021	and	2020	these	rates	were	favorable	to	the	rates	of	our	peers.	

Leadership	Development	and	Training	Programs	-	We	extend	leadership	development	throughout	the	organization	to	build	enterprise-wide	

understanding	of	our	culture,	strategy	and	processes.	Annual	succession	planning,	individual	development	planning,	mentoring,	and	supervisory

OTP,	headquartered	in	Fergus	Falls,	Minnesota,	is	a	vertically	integrated,	regulated	utility	with	generation,	transmission	and	distribution	facilities	to	
serve	its	more	than	133,000	residential,	industrial	and	commercial	customers	in	a	service	area	encompassing	approximately	70,000	square	miles	of	
western	Minnesota,	eastern	North	Dakota	and	northeastern	South	Dakota.	

CUSTOMERS
Our	service	territory	is	predominantly	rural	and	agricultural	and	includes	over	400	communities,	most	of	which	have	populations	of	less	than	
10,000.	While	our	customer	base	includes	relatively	few	large	customers,	sales	to	commercial	and	industrial	customers	are	significant,	with	one	
industrial	customer	accounting	for	10%	of	segment	operating	revenues	for	the	year	ended	December	31,	2021.	

The	following	charts	summarize	our	retail	electric	revenues	by	state	and	by	customer	segment	for	the	years	ended	December	31,	2021	and	2020:

In	addition	to	retail	revenue,	our	Electric	segment	also	generates	operating	revenues	from	the	transmission	of	electricity	for	others	over	the	
transmission	assets	we	wholly	or	jointly	own	with	other	transmission	service	providers,	and	from	the	sale	of	electricity	we	generate	and	sell	into	the	
wholesale	electricity	market.	

COMPETITIVE	CONDITIONS
Retail	electric	sales	are	made	to	customers	in	assigned	service	territories.	As	a	result,	most	retail	customers	do	not	have	the	ability	to	choose	their	
electric	supplier.	Competition	is	present	in	some	areas	from	municipally	owned	systems,	rural	electric	cooperatives	and,	in	certain	respects,	from	
on-site	generators	and	co-generators.	Electricity	also	competes	with	other	forms	of	energy.	

Competition	also	arises	from	customers	supplying	their	own	power	through	distributed	generation,	which	is	the	generation	of	electricity	on-site	or	
close	to	where	it	is	needed	in	small	facilities	designed	to	meet	local	needs.	Distributed	energy	resources	can	include	combined	heat	and	power,	
solar	photovoltaic,	wind,	battery	storage,	thermal	storage	and	demand-response	technologies.

The	degree	of	competition	may	vary	from	time	to	time	depending	on	relative	costs	and	supplies	of	other	forms	of	energy	and	advances	in	
technology.	Irrespective	of	the	competitive	environment,	we	are	focused	on	providing	value	to	our	customers	and	ensuring	our	retail	rates	remain	
among	the	lowest	in	the	region	and	in	the	nation.	

The	following	table	presents	our	average	retail	rate	per	kilowatt-hour	(kwh)	by	customer	class	and	in	total	for	the	years	ended	December	31,	2021

Wholesale	electricity	markets	are	competitive	under	the	Federal	Energy	Regulatory	Commission	(FERC)	open	access	transmission	tariffs,	which	
require	utilities	to	provide	nondiscriminatory	access	to	all	wholesale	users.	In	addition,	the	FERC	has	established	a	competitive	process	for	the	
construction	and	operation	of	certain	new	electric	transmission	facilities	whereby	electric	transmission	providers,	including	the	Midcontinent	
Independent	System	Operator,	Inc.	(MISO),	of	which	OTP	is	a	member,	are	required	to	remove	from	their	tariffs	a	federal	right	of	first	refusal	to	
construct	transmission	facilities	selected	in	a	regional	transmission	plan	for	purposes	of	cost	allocation.	The	FERC	is	contemplating	potential	
reforms	for	electric	regional	transmission	planning,	cost	allocation	and	generator	interconnection	processes.	While	the	ultimate	regulatory	
outcome	is	uncertain	at	this	time,	changes	to	the	regulatory	framework	could	impact	future	transmission	investments.	

Franchises
OTP	has	franchises	to	operate	as	an	electric	utility	in	substantially	all	of	the	incorporated	municipalities	it	serves.	Franchise	rights	generally	require	
periodic	renewal.	No	franchises	are	required	to	serve	unincorporated	communities	in	any	of	the	three	states	OTP	serves.	

GENERATION	AND	PURCHASED	POWER
OTP	primarily	relies	on	company-owned	generation,	supplemented	by	purchase	power	agreements,	to	supply	the	energy	to	meet	our	customer	
needs.	Wholesale	market	purchases	and	sales	of	electricity	are	used	as	necessary	to	balance	supply	and	demand.	Our	mix	of	owned	generation	and	
wholesale	market	energy	purchases	to	meet	customer	demand	are	impacted	by	wholesale	energy	prices	and	the	relative	cost	of	each	energy	
source.

Capacity	Retirements	and	Additions
Hoot	Lake	Plant,	our	142-megawatt	coal-fired	power	plant	in	Fergus	Falls,	Minnesota	was	retired	in	mid-2021.	

As	part	of	our	investment	plan	to	meet	our	future	energy	needs,	we	have	the	following	significant	projects	at	various	stages	of	planning	and	
construction	or	that	have	been	recently	completed:	

Merricourt	Wind	Energy	Center	(Merricourt)	is	a	150-megawatt	wind	farm	located	in	southeastern	North	Dakota.	Construction	of	the	wind	

farm	commenced	in	2019	and	the	facility	was	placed	into	commercial	operation	in	December	2020,	with	a	total	cost	of	approximately	$260	million.

	Astoria	Station	Natural	Gas	Plant	(Astoria)	is	a	245-megawatt	simple	cycle	natural	gas	combustion	turbine	generation	facility	near	Astoria,	

South	Dakota.	Construction	commenced	in	2019	and	the	facility	was	placed	into	commercial	operation	in	February	2021,	with	a	total	cost	of	
approximately	$160	million.

Hoot	Lake	Solar	is	a	49-megawatt	solar	farm	under	development	on	land	on	and	around	our	Hoot	Lake	Plant	in	Fergus	Falls,	Minnesota,	with	

an	anticipated	cost	of	approximately	$60	million.	We	anticipate	the	facility	will	be	in	commercial	operation	by	the	end	of	2023.	

ENERGY	TRANSITION
Otter	Tail	Power	is	committed	to	transitioning	to	a	lower-carbon	and	increasingly	clean	energy	future,	while	maintaining	low	cost	and	reliable	
electricity	to	serve	our	customers.	We	have	developed	the	following	goals	in	the	furtherance	of	our	efforts	to	support	the	energy	transition:

Provide	30%	of	energy	generated	from	renewable	resources	to	our	customers	by	2023.

Reduce	carbon	emissions	from	owned	generation	resources	by	50%	by	2025	from	2005	levels.

Reduce	carbon	emissions	from	owned	generation	resources	by	97%	by	2050	from	2005	levels.	

To	date,	we	have	undertaken	numerous	initiatives	to	reduce	our	carbon	footprint	and	mitigate	greenhouse	gas	emissions	in	the	process	of	
generating	electricity	for	our	customers.	Our	initiatives	include	increasing	the	efficiency	of	our	plants,	adding	renewable	energy	to	our	resource	mix	
and	sponsoring	energy	conservation	programs.	

From	2005	through	2021,	we	have	reduced	our	carbon	dioxide	emissions	approximately	39%	and	increased	the	amount	of	renewable	generation	
resources	we	own	or	contract	through	purchase	power	agreements	by	approximately	370	megawatts.	Our	future	resource	plans	to	deliver	low-
cost,	reliable	and	increasingly	clean	energy	to	our	customers	include	the	addition	of	49	megawatts	of	solar	energy	from	Hoot	Lake	Solar	in	2023	
along	with	the	resource	additions	as	outlined	in	our	Integrated	Resource	Plan,	including	the	addition	of	150	megawatts	of	solar	generation	and	100	
megawatts	of	wind	generation	by	2027.	Our	resource	plan	also	proposes	to	withdraw	from	Coyote	Station,	our	jointly	owned	coal-fired	generation	
facility	by	the	end	of	2028.

resources,	procured	through	purchase	power	agreements	and	energy	purchased	in	the	wholesale	market:

RESOURCE	MATERIALS
Coal	is	the	principal	fuel	burned	at	our	jointly-owned	Big	Stone	and	Coyote	Station	generating	plants.	Coyote	Station,	a	mine-mouth	facility,	burns	
North	Dakota	lignite	coal.	Big	Stone	Plant	burns	western	subbituminous	coal	transported	by	rail.	We	source	coal	for	our	coal-fired	power	plants	
through	requirements	contracts	which	do	not	include	minimum	purchase	requirements	but	do	require	all	coal	necessary	for	the	operation	of	the	
respective	plant	to	be	purchased	from	the	counterparty.	Our	coal	supply	contracts	for	our	Big	Stone	Plant	and	Coyote	Station	have	expiration	dates	
in	2022	and	2040,	respectively.	

The	supply	agreement	between	the	Coyote	Station	owners,	including	OTP,	and	the	coal	supplier	includes	provisions	requiring	the	Coyote	Station	
owners	to	purchase	the	membership	interests	and	pay	off	or	assume	loan	and	lease	obligations	of	the	coal	supplier,	as	well	as	complete	mine	
closing	and	post-mining	reclamation,	in	the	event	of	certain	early	termination	events	and	at	the	expiration	of	the	coal	supply	agreement	in	2040.	
See	Note	1	to	our	consolidated	financial	statements	included	in	this	report	on	Form	10-K	for	additional	information.

Coal	is	transported	to	our	non-mine-mouth	facility,	Big	Stone	Plant,	by	rail	and	is	provided	under	a	common	carrier	rate	which	includes	a	mileage-
based	fuel	surcharge.

We	purchase	natural	gas	for	use	at	our	combustion	turbine	facilities	based	on	anticipated	short-term	resource	needs.	We	procure	natural	gas	from	
multiple	vendors	at	spot	prices	in	a	liquid	market	primarily	under	firm	delivery	contracts.

TRANSMISSION	AND	DISTRIBUTION
Our	transmission	and	distribution	assets	deliver	energy	from	energy	generation	sources	to	our	customers.	In	addition,	we	earn	revenue	from	the	
transmission	of	electricity	over	our	wholly	or	jointly	owned	transmission	assets	for	others	under	approved	rate	tariffs.	As	of	December	31,	2021,	we	
were	the	sole	or	joint	owner	of	over	9,000	miles	of	transmission	and	distribution	lines.		

Midcontinent	Independent	System	Operator,	Inc.	(MISO)
MISO	is	an	independent,	non-profit	organization	that	operates	the	transmission	facilities	owned	by	other	entities,	including	OTP,	within	its	regional	
jurisdiction	and	administers	energy	and	generation	capacity	markets.	MISO	has	operational	control	of	our	transmission	facilities	above	100	kiloVolts	
(kV).	MISO	seeks	to	optimize	the	efficiency	of	the	interconnected	system,	provide	solutions	to	regional	planning	needs	and	minimize	risk	to	
reliability	through	its	security	coordination,	long-term	regional	planning,	market	monitoring,	scheduling	and	tariff	administration	functions.

SEASONALITY
Electricity	demand	is	affected	by	seasonal	weather	differences,	with	peak	demand	occurring	in	the	summer	and	winter	months.	As	a	result,	our	
Electric	segment	operating	results	regularly	fluctuate	on	a	seasonal	basis.	In	addition,	fluctuations	in	electricity	demand	within	the	same	season	but	
between	years	can	impact	our	operating	results.	We	monitor	the	level	of	heating	and	cooling	degree	days	in	a	period	to	assess	the	impact	of	
weather-related	effects	on	our	operating	results	between	periods.	

PUBLIC	UTILITY	REGULATION
OTP	is	subject	to	regulation	of	rates	and	other	matters	in	each	of	the	three	states	in	which	it	operates	and	by	the	federal	government	for,	among	
other	matters,	the	interstate	transmission	of	electricity.	OTP	operates	under	approved	retail	electric	tariff	rates	in	all	three	states	it	serves.	Tariff	
rates	are	designed	to	recover	plant	investments,	a	return	on	those	investments	and	operating	costs.	In	addition	to	determining	rate	tariffs,	state	
regulatory	commissions	also	authorize	return	on	equity	(ROE),	capital	structure	and	depreciation	rates	of	our	plant	investments.	Decisions	by	our	
regulators	significantly	impact	our	operating	results,	financial	position	and	cash	flows.

Minnesota	has	a	renewable	energy	standard	requiring	utilities	to	generate	or	procure	sufficient	renewable	generation	such	that	the	following	
percentages	of	total	retail	electric	sales	to	Minnesota	customers	come	from	qualifying	renewable	sources:	17%	by	2016;	20%	by	2020	and	25%	by	
2025.	We	met	the	current	renewable	sources	requirements	with	a	combination	of	owned	renewable	generation	and	purchases	from	renewable	
generation	sources.	Minnesota	law	also	requires	1.5%	of	total	Minnesota	electric	sales	by	public	utilities	to	be	supplied	by	solar	energy.	For	a	public	
utility	with	between	50,000	and	200,000	retail	electric	customers,	such	as	OTP,	at	least	10%	of	the	1.5%	requirement	must	be	met	by	solar	energy	
generated	by	or	procured	from	solar	photovoltaic	devices	with	a	nameplate	capacity	of	40	kWs	or	less.	OTP	plans	to	purchase	Solar	Renewable	
Energy	Credits	(SRECs)	to	meet	its	obligations	until	its	Hoot	Lake	Solar	and	other	solar	projects	are	complete	and	operational.	OTP	plans	to	purchase	
SRECs	to	meet	its	2021	obligation,	for	which	compliance	will	be	measured	as	of	April	30,	2022.

10

Under	certain	circumstances	and	after	consideration	of	costs	and	reliability	issues,	the	MPUC	may	modify	or	delay	implementation	of	the	
standards.	We	are	evaluating	potential	options	for	maintaining	compliance	and	meeting	the	solar	energy	standard	beyond	2021.	

Integrated	Resource	Plan	(IRP)
Under	Minnesota	law,	utilities	are	required	to	submit	for	approval	by	the	MPUC	a	15-year	advance	IRP.	An	IRP	is	a	set	of	resource	options	a	utility	
could	use	to	meet	the	service	needs	of	its	customers	over	the	forecast	period,	including	an	explanation	of	the	utility’s	supply	and	demand	
circumstances,	and	the	extent	to	which	each	resource	option	would	be	used	to	meet	those	service	needs.	The	MPUC’s	findings	of	fact	and	
conclusions	regarding	IRPs	are	considered	to	be	prima	facie	evidence,	subject	to	rebuttal,	in	future	rate	reviews	and	other	proceedings.	Typically,	
IRPs	are	submitted	every	two	years.

In	2021,	the	North	Dakota	Legislative	Assembly	enacted	a	provision	requiring	investor-owned	electric	utilities	to	submit	an	IRP	to	the	NDPSC	and	
granted	the	NDPSC	the	authority	to	adopt	rules	and	regulations	for	the	preparation	and	submission	of	integrated	resource	plans.	To	date,	the	
NDPSC	has	not	established	any	formal	rules	and	regulations.

On	September	1,	2021,	OTP	filed	its	2022	IRP	concurrently	with	regulators	in	the	three	states	where	OTP	operates,	Minnesota,	North	Dakota	and	
South	Dakota.	The	2022	IRP	includes	OTP’s	preferred	plan	for	meeting	customers’	anticipated	capacity	and	energy	needs	while	maintaining	system	
reliability	and	low	electric	service	rates.

The	components	of	OTP's	preferred	plan	include:

•

•

•

•

•

the	addition	of	dual	fuel	capability	at	our	Astoria	Station	natural	gas	plant,	allowing	for	the	plant	to	burn	fuel	oil	in	addition	to	natural	gas;

the	addition	of	150	megawatts	of	solar	generation	in	2025;

the	addition	of	100	megawatts	of	wind	generation	in	2027;	

the	commencement	of	the	process	of	withdrawing	from	our	35	percent	ownership	interest	in	Coyote	Station,	a	jointly	owned,	coal-fired	
generation	plant,	by	December	31,	2028;	and

the	addition	of	50	megawatts	of	solar	generation	in	2033.

The	2022	IRP	includes	requests	for	approval	of	certain	activities	planned	to	commence	within	the	next	five	years,	which	include	the	addition	of	dual	
fuel	capacity	at	our	Astoria	Station	natural	gas	plant,	the	addition	of	150	megawatts	of	solar	generation	and	commencement	of	the	withdrawal	
from	our	ownership	interest	in	Coyote	Station.	Although	the	2022	IRP	includes	planned	actions	beyond	2026,	regulators	will	not	act	upon	or	
approve	planned	actions	in	periods	beyond	2026	as	part	of	our	2022	IRP	filing.

The	preferred	plan	proposes	to,	subject	to	regulatory	approval,	create	a	regulatory	asset	as	a	vehicle	to	recover	costs	related	to	a	future	withdrawal	
from	Coyote	Station,	including	the	net	book	value	of	the	plant	on	the	withdrawal	date,	anticipated	decommissioning	costs	and	any	required	costs	
incurred	as	a	result	of	an	early	termination	of	the	existing	lignite	sales	agreement,	under	which	Coyote	Station	acquires	all	of	its	lignite	coal	from	a	
nearby	mine.	As	part	of	the	filing,	OTP	developed	an	estimate	of	the	reasonably	foreseeable	costs	of	withdrawing	from	Coyote	Station	at	the	end	of	
2028	of	$68.5	million.	These	costs	may	differ	from	actual	results	due	to	the	uncertainty	and	timing	of	future	events	associated	with	the	terms	and	
conditions	of	a	withdrawal.	

Capital	Structure	Petition
Minnesota	law	requires	an	annual	filing	of	a	capital	structure	petition	with	the	MPUC.	In	this	filing	the	MPUC	reviews	and	approves	OTP's	capital	
structure.	Once	approved,	OTP	may	issue	securities	without	further	petition	or	approval,	provided	the	issuance	is	consistent	with	the	purposes	and	
amounts	set	forth	in	the	approved	petition.	OTP’s	current	capital	structure	approved	by	the	MPUC	on	January	26,	2022,	allows	for	an	equity-to-
total-capitalization	ratio	between	48.0%	and	58.7%,	with	total	capitalization	not	to	exceed	$1.7	billion.	

ENVIRONMENTAL	REGULATION
OTP	is	subject	to	stringent	federal	and	state	environmental	standards	and	regulations	regarding,	among	other	things,	air,	water	and	solid	waste	
pollution.	OTP's	facilities	have	been	designed,	constructed	and,	as	necessary,	updated	to	operate	in	compliance	with	applicable	environmental	
regulations.	However,	new	or	amended	laws	and	regulations	or	changes	in	interpretations	of	current	laws	and	regulations	may	require	additional	
pollution	control	equipment	or	emission	reduction	measures	and	there	can	be	no	assurance	that	our	facilities	will	remain	economic	to	operate.	
Prudent	expenditures	incurred	to	comply	with	environmental	regulations	are	eligible	to	be	recovered	in	rates	granted	by	regulators	in	jurisdictions	
in	which	we	operate;	however,	there	can	be	no	assurance	that	future	costs	will	be	granted	recovery.	Alternatively,	additional	pollution	control	
equipment	or	other	emission	reduction	measures	may	prove	to	be	uneconomic	with	the	potential	to	lead	to	the	exiting	of	a	facility	earlier	than	
originally	planned.	As	it	relates	to	our	jointly	owned	facilities,	we	may	determine	it	is	necessary	to	transfer,	sell	or	otherwise	divest	of	our	
ownership,	or	the	ownership	group	may	determine	the	early	closure	of	a	facility	is	necessary.

For	the	five-year	period	ended	December	31,	2021,	OTP	invested	approximately	$13.3	million,	including	$0.9	million	in	2021,	in	environmental	
control	facilities.	Our	construction	budgets	for	the	next	five	years	include	an	approximately	$6.0	million	of	capital	investments	in	environmental	
control	equipment.	The	timing	and	amount	of	our	expenditures	may	change	as	the	regulatory	environment	changes.	

Among	current	regulatory	requirements,	the	Regional	Haze	Rule	(RHR)	could	have	the	most	significant	impact	on	our	operating	results,	financial	
condition	and	liquidity.	

The	Environmental	Protection	Agency	(EPA)	adopted	the	RHR	in	1999	as	an	effort	to	improve	visibility	in	national	parks	and	wilderness	areas.	The	
RHR	requires	states,	in	coordination	with	the	EPA	and	other	governmental	agencies,	to	develop	and	implement	plans	to	work	towards	achieving	
natural	visibility	conditions	by	the	year	2064.	The	second	RHR	implementation	period	covers	the	years	2018-2028.	States	are	required	to	submit	a	
state	implementation	plan	to	assess	reasonable	progress	with	the	RHR	and	determine	what	additional	emission	reductions	are	appropriate,	if	any.	

11

Coyote	Station,	OTP's	co-owned	coal-fired	power	plant	in	North	Dakota	is	subject	to	assessment	in	the	second	implementation	period	under	the	
North	Dakota	state	implementation	plan.	In	September	2021,	the	North	Dakota	Department	of	Environmental	Quality	(NDDEQ)	made	public	a	draft	
of	its	state	implementation	plan.	The	plan	concluded	it	is	not	reasonable	to	require	additional	emission	controls	during	this	planning	period.	
Following	a	consultation	and	public	comment	period	and	any	subsequent	modifications	to	the	plan,	the	NDDEQ	will	submit	its	state	
implementation	plan	to	the	EPA	for	approval.	In	January	2022,	the	EPA	provided	preliminary	comments	on	the	North	Dakota	state	implementation	
plan	in	which	it	expressed	disagreement	with	the	NDDEQ's	recommendation	to	forgo	additional	emission	controls.		See	Note	13	to	our	consolidated	
financial	statements	included	in	the	report	on	Form	10-K	for	additional	information.		

Climate	Change	and	Greenhouse	Gas	Regulation
Global	climate	change	presents	a	significant	energy	and	environmental	policy	challenge.	Combustion	of	fossil	fuels	for	the	generation	of	electricity	
is	a	considerable	source	of	carbon	dioxide	(CO2)	emissions,	which	is	the	primary	greenhouse	gas	(GHG)	emitted	by	our	utility	operations.	The	
federal	government	and	many	states	are	pursuing	climate	policies	to	regulate	GHG	emissions	as	part	of	a	broad	based	effort	to	limit	global	
warming.	

In	February	2021,	the	U.S.	rejoined	the	United	Nations	Framework	Convention	on	Climate	Change	(the	Paris	Agreement),	which	is	a	legally	binding	
international	treaty	on	climate	change	adopted	by	over	190	countries.	The	goal	of	the	Paris	Agreement	is	to	limit	global	temperature	increase	to	
well	below	2°	Celsius	compared	to	pre-industrial	levels	and	to	pursue	efforts	to	limit	the	temperature	increase	to	1.5°	Celsius.	The	Biden	
Administration	has	announced	the	goal	of	reducing	greenhouse	gas	emissions	by	50	to	52	percent	from	2005	levels	in	2030	and	to	reach	100	
percent	carbon	pollution-free	electricity	by	2035	as	part	of	the	U.S.	plan	to	achieve	the	goals	under	the	Paris	Agreement.				

The	implementation	of	climate	change	programs,	such	as	the	Paris	Agreement,	and	federal	or	state	regulations	targeting	GHG	emissions	may	have	
a	significant	impact	on	our	utility	business.	Specific	regulatory	measures	to	address	climate	change	continue	to	evolve.	In	January	2021,	the	EPA's	
Affordable	Clean	Energy	Rule	(ACE	Rule),	which	required	states	to	develop	plans	for	GHG	emissions	from	coal-fired	power	plants,	was	vacated	by	
the	U.S.	Court	of	Appeals	for	the	District	of	Columbia	Circuit.	In	October	2021,	the	U.S.	Supreme	Court	agreed	to	hear	a	consolidated	challenge	to	
the	Court	of	Appeals	decision.	The	Supreme	Court's	decision,	expected	in	mid-2022,	could	significantly	impact	the	legal	authority	of	the	EPA	to	
regulate	CO2	and	other	greenhouse	gas	emissions.	

While	the	future	financial	impact	of	any	current,	proposed	or	pending	litigation	or	regulation	of	GHG	or	other	emissions	is	unknown	at	this	time,	
any	capital	or	operating	costs	incurred	for	additional	pollution	control	equipment	or	emission	reduction	measures	could	materially	adversely	
impact	our	future	operating	results,	financial	position	and	liquidity	unless	such	costs	could	be	recovered	through	related	rates	and/or	future	market	
prices	for	energy.				

MANUFACTURING

Contribution	to	Operating	Revenues:	28%	(2021),	27%	(2020),	30%	(2019)

Manufacturing	consists	of	businesses	engaged	in	the	following	activities:	contract	machining,	metal	parts	stamping,	fabrication	and	painting,	and	
production	of	plastic	thermoformed	horticultural	containers,	life	science	and	industrial	packaging,	and	material	handling	components	and	extruded	
raw	material	stock.	The	following	is	a	brief	description	of	each	of	these	businesses:

BTD	Manufacturing,	Inc.	(BTD),	with	headquarters	located	in	Detroit	Lakes,	Minnesota,	provides	metal	fabrication	services	for	custom	

machine	parts	and	metal	components	through	metal	stamping,	tool	and	die,	machining,	tube	bending,	welding	and	assembly	in	its	facilities	in	
Detroit	Lakes	and	Lakeville,	Minnesota,	Washington,	Illinois	and	Dawsonville,	Georgia.

T.O.	Plastics,	Inc.	(T.O.	Plastics),	with	facilities	in	Otsego	and	Clearwater,	Minnesota,	manufactures	extruded	and	thermoformed	plastic	
products,	including	custom	parts	for	customers	in	several	industries	and	its	own	line	of	horticulture	containers.	Examples	of	products	produced	
include	clamshell	packing,	blister	packs,	returnable	pallets	and	handling	trays	for	shipping	and	storing	odd-shaped	or	difficult-to-handle	parts.

CUSTOMERS
Our	metal	fabrication	business	primarily	serves	Midwestern	and	Southeastern	U.S.	manufacturers	in	the	recreational	vehicle,	lawn	and	garden,	
agricultural,	construction,	and	industrial	and	energy	equipment	end	markets.	Our	plastic	products	business	serves	primarily	U.S.	customers	in	the	
horticulture,	medical	and	life	sciences,	industrial,	recreational	and	electronics	industries.	The	principal	method	of	production	distribution	is	by	
direct	shipment	to	our	customers	through	direct	customer	pick-up	or	common	carrier	ground	transportation.

No	single	customer	or	product	of	our	manufacturing	businesses	accounted	for	10%	or	more	of	our	consolidated	operating	revenue	in	2021.	
However,	the	top	three	customers	combined	to	account	for	46%	of	our	2021	Manufacturing	segment	operating	revenue.

COMPETITIVE	CONDITIONS
The	various	markets	in	which	we	compete	are	characterized	by	intense	competition	from	both	foreign	and	domestic	manufacturers.	These	markets	
have	many	established	manufacturers	with	broader	product	lines,	greater	distribution	capabilities,	greater	capital	resources,	excess	capacity,	labor	
advantages	and	larger	marketing,	research	and	development	staffs	and	facilities	than	our	own.

We	believe	the	principal	competitive	factors	in	our	Manufacturing	segment	are	product	performance,	quality,	price,	technical	innovation,	cost	
effectiveness,	customer	service	and	breadth	of	product	line.	We	intend	to	continue	to	compete	based	on	high-performance	products,	innovative	
production	technologies,	cost-effective	manufacturing	techniques,	close	customer	relations	and	support,	and	increasing	product	offerings.	

RESOURCE	MATERIALS
We	use	raw	materials	in	the	products	we	manufacture,	including,	among	others,	steel,	aluminum,	and	polystyrene	and	other	plastics	resins.	
Managing	price	volatility	and	ensuring	raw	material	availability	are	important	aspects	of	our	business.	We	attempt	to	pass	increases	in	the	costs	of	

12

these	raw	materials	on	to	our	customers.	Increases	in	the	costs	of	raw	materials	that	cannot	be	passed	on	to	customers	could	have	a	negative	
effect	on	profit	margins.	Additionally,	a	certain	amount	of	residual	material	(scrap)	is	a	by-product	of	the	manufacturing	and	production	processes.	
Declines	in	commodity	prices	for	these	scrap	materials	due	to	weakened	demand	or	excess	supply	can	negatively	impact	the	profitability	of	our	
Manufacturing	segment	as	it	reduces	their	ability	to	mitigate	the	cost	associated	with	excess	material.

ENVIRONMENTAL	REGULATION
Our	manufacturing	businesses	are	subject	to	environmental,	health	and	safety	laws	and	regulations,	including	those	governing	discharges	to	air	and	
water,	the	management	and	disposal	of	hazardous	substances,	the	cleanup	of	contaminated	sites	and	health	and	safety	matters.	

PLASTICS

Contribution	to	Operating	Revenues:	32%	(2021),	23%	(2020),	20%	(2019)

Plastics	consists	of	businesses	producing	PVC	pipe	at	plants	in	North	Dakota	and	Arizona.	The	following	is	a	brief	description	of	these	businesses:

Northern	Pipe	Products,	Inc.	(Northern	Pipe),	located	in	Fargo,	North	Dakota,	manufactures	and	sells	PVC	pipe	for	municipal	water,	rural	
water,	wastewater,	storm	drainage	systems	and	other	uses	in	the	northern,	midwestern,	south-central	and	western	regions	of	the	United	States	as	
well	as	central	and	western	Canada.

Vinyltech	Corporation	(Vinyltech),	located	in	Phoenix,	Arizona,	manufactures	and	sells	PVC	pipe	for	municipal	water,	wastewater,	water	

reclamation	systems	and	other	uses	in	the	western,	northwest	and	south-central	regions	of	the	United	States.

PVC	pipe	is	manufactured	through	a	process	known	as	extrusion.	During	this	process,	PVC	compound	(a	dry	powder-like	substance)	is	introduced	
into	an	extrusion	machine,	where	it	is	heated	to	a	molten	state	and	then	forced	through	a	sizing	apparatus	to	produce	the	pipe.	The	newly	extruded	
pipe	is	pulled	through	a	series	of	water-cooling	tanks,	marked	to	identify	the	type	of	pipe	and	cut	to	finished	lengths.

CUSTOMERS
PVC	pipe	products	are	marketed	through	a	combination	of	independent	sales	representatives,	company	salespersons	and	customer	service	
representatives.	Customers	for	our	PVC	pipe	products	consist	primarily	of	wholesalers	and	distributors	and	the	principal	method	for	distribution	of	
our	products	is	by	common	carrier	ground	transportation.	No	single	customer	of	the	PVC	pipe	companies	accounted	for	10%	or	more	of	our	
consolidated	operating	revenues	in	2021.	However,	two	customers,	both	of	which	are	distributors	of	PCV	pipe,	combined	to	account	for	50%	of	our	
2021	Plastics	segment	operating	revenue.

COMPETITIVE	CONDITIONS
The	plastic	pipe	industry	is	fragmented	and	competitive	due	to	the	number	of	producers,	the	small	number	of	raw	material	suppliers	and	the	
fungible	nature	of	the	product.	Due	to	shipping	costs,	competition	is	usually	regional,	instead	of	national,	in	scope.	The	principal	factors	of	
competition	are	price,	customer	service	and	product	performance.	We	compete	not	only	against	other	plastic	pipe	manufacturers,	but	also	ductile	
iron,	high-density	polyethylene,	steel	and	concrete	pipe	producers.	Pricing	pressure	will	continue	to	affect	our	operating	margins	in	the	future.

We	will	continue	to	compete	based	on	our	high-quality	products,	cost-effective	production	techniques	and	close	customer	relations	and	support.

RESOURCE	MATERIALS
PVC	resins	are	acquired	in	bulk	and	shipped	to	our	facilities	by	rail.	There	are	four	vendors	from	which	we	can	source	our	PVC	resin	requirements.	In	
2021	we	sourced	all	of	our	PVC	resin	needs	from	two	vendors.	The	supply	of	PVC	resin	may	also	be	limited	primarily	due	to	manufacturing	capacity	
and	the	limited	availability	of	raw	material	components.	Most	U.S.	resin	production	plants	are	located	in	the	Gulf	Coast	region.	These	plants	are	
subject	to	the	risk	of	damage	and	production	shutdowns	because	of	exposure	to	hurricanes	or	other	extreme	weather	events	that	occur	in	this	part	
of	the	United	States.	The	loss	of	a	key	vendor,	or	any	interruption	or	delay	in	the	supply	of	PVC	resin	could	disrupt	the	ability	of	the	Plastics	
segment	to	manufacture	products,	cause	customers	to	cancel	orders	or	result	in	increased	expenses	for	obtaining	PVC	resin	from	alternative	
sources,	if	such	sources	were	available.	We	believe	we	have	good	relationships	with	our	key	raw	material	vendors.

Due	to	the	commodity	nature	of	PVC	resin	and	PVC	pipe	and	the	dynamic	supply	and	demand	factors	worldwide,	historically	the	markets	for	both	
PVC	resin	and	PVC	pipe	have	been	very	cyclical	with	significant	fluctuations	in	prices	and	gross	margins.

In	addition	to	PVC	resin,	we	use	certain	other	materials,	such	as	tin	stabilizer,	gaskets	and	lumber,	in	the	process	of	manufacturing	and	shipping	our	
PVC	pipe	products.	We	generally	source	these	materials	from	a	limited	number	of	suppliers,	and	supply	chain	constraints	or	disruptions	related	to	
these	materials	could	disrupt	our	ability	to	manufacture	or	ship	products	and	could	result	in	increased	costs.

SEASONALITY
Demand	for	our	PVC	pipe	products	can	be	impacted	by	seasonal	weather	differences,	with	generally	lower	sales	volumes	realized	in	the	first	
quarter	of	the	year	when	cold	temperatures	and	frozen	ground	across	the	northern	portion	of	our	footprint	can	delay	or	prevent	construction	
activity.

ITEM	1A. RISK	FACTORS

RISK	FACTORS	AND	CAUTIONARY	STATEMENTS
Our	businesses	are	subject	to	various	risks	and	uncertainties.	Any	of	the	risks	described	below	or	elsewhere	in	this	report	on	Form	10-K	or	in	our	
other	SEC	filings	could	materially	adversely	affect	our	business,	operating	results,	financial	condition	and	liquidity.	Additional	risks	and	uncertainties	
we	are	not	presently	aware	of	or	that	we	currently	consider	immaterial	may	also	affect	our	business,	operating	results,	financial	condition	and	
liquidity.

Oversight	of	Risk	and	Related	Processes	
A	key	accountability	of	the	Board	of	Directors	is	the	oversight	of	material	risk.	Management	and	the	Board	of	Directors	have	responsibility	for	
overseeing	the	identification	and	mitigation	of	significant	and	emerging	risks.	Management	identifies	and	analyzes	risks	to	determine	the	impact	
and	other	attributes	such	as	timing,	likelihood	and	management	control.	Identification	and	analysis	occur	formally	through	an	assessment	of	
significant	and	emerging	risks	conducted	by	senior	management,	the	financial	disclosure	process,	and	internal	auditing	and	compliance	with	
financial	and	operational	controls.	Management	also	identifies	and	analyzes	risk	through	development	of	goals	and	key	performance	indicators,	
which	include	risk	identification	to	determine	barriers	to	implementing	our	strategy.	We	promote	a	culture	of	compliance,	including	tone	at	the	
top.	The	process	for	risk	mitigation	includes	adherence	to	our	code	of	business	ethics	and	compliance	policies,	operation	of	formal	risk	
management	structures	and	overall	business	management	to	mitigate	the	risks	inherent	in	the	implementation	of	strategy.	We	manage	and	further	
mitigate	risks	through	formal	risk	management	structures,	including	a	management	executive	risk	committee	and	services	such	as	internal	audit/
business	risk	management	and	legal.	Management	communicates	regularly	with	our	Board	of	Directors	and	key	stakeholders	regarding	risk.	Senior	
management	presents	and	communicates	a	periodic	risk	assessment	to	our	Board	of	Directors	which	provides	information	on	the	risks	
management	believes	are	material,	including	the	earnings	impact,	timing,	likelihood	and	management	control.	The	Board	of	Directors	approaches	
oversight,	management	and	mitigation	of	risk	as	an	integral	and	continuous	part	of	its	governance	of	OTC.	The	Board	of	Directors	regularly	reviews	
management’s	top	risk	assessment	and	analyzes	areas	of	existing	and	future	risks	and	opportunities.	Finally,	the	Board	of	Directors	conducts	an	
annual	strategy	session	where	our	future	plans	and	initiatives	are	reviewed.

OPERATIONAL	RISKS

The	economic	effects	of	the	coronavirus	(COVID-19)	pandemic	and	measures	taken	to	reduce	and	slow	the	spread	of	the	virus	could	adversely	
impact	our	business.
The	outbreak	and	global	spread	of	COVID-19,	which	was	declared	a	pandemic	by	the	World	Health	Organization	in	March	2020,	continues	to	have	
widespread	and	unpredictable	impacts	on	society,	economies,	financial	markets	and	businesses	everywhere.	The	COVID-19	pandemic	has	impacted	
our	business	operations,	including	our	employees,	customers,	construction	contractors,	suppliers	and	vendors,	and	there	is	substantial	uncertainty	
in	the	nature	and	degree	of	the	continued	effects	over	time.	In	2021,	our	business	was	impacted	by	supply	chain	disruptions	and	labor	shortages	
resulting	from	the	pandemic,	and	the	associated	costs	and	inflation	related	thereto.	The	extent	to	which	COVID-19	impacts	our	business	going	
forward	is	highly	uncertain	and	will	depend	on	future	developments	including	the	efficacy	of	vaccines,	the	spread	of	COVID-19	variants	and	the	
extent	of	federal,	state	and	local	government	responses,	including	potential	vaccine	or	testing	mandates.	

On	November	5,	2021,	OSHA	issued	an	Emergency	Temporary	Standard	(“ETS”)	requiring	that	most	employers	with	at	least	100	employees	ensure	
that	their	employees	are	fully	vaccinated	for	COVID-19	or	require	their	employees	to	obtain	a	negative	COVID-19	test	at	least	once	a	week.	On	
January	13,	2022,	the	US	Supreme	Court	granted	emergency	relief	to	stay	the	implementation	of	the	OSHA	ETS	and	on	January	26,	2022,	OSHA	
withdrew	its	ETS.	Despite	withdrawing	the	ETS	as	an	enforceable	standard,	OSHA	emphasized	that	the	ETS	will	continue	to	serve	as	its	proposal	for	
a	permanent	standard.	Additionally,	on	September	9,	2021,	President	Biden	issued	an	executive	order	requiring	employees	of	certain	federal	
contractors	and	covered	subcontractors	to	be	vaccinated,	with	no	weekly	testing	option,	unless	they	have	an	approved	disability	or	religious	
exemption.	Currently,	the	mandate	set	forth	by	the	executive	order	has	been	halted	as	several	states	are	challenging	its	legality	and	the	matter	
remains	in	litigation.	If	these	mandates	are	upheld	in	federal	court	and	become	effective,	we	expect	one,	or	both,	of	these	new	regulations	will	
apply	to	at	least	some,	and	possibly	all,	of	our	businesses	which	could	require	us	to	mandate	COVID-19	vaccination	of	our	workforce	or	have	our	
unvaccinated	employees	undergo	required	weekly	COVID-19	testing,	or	some	combination	thereof,	which	could	be	difficult	and	costly.	Further,	
additional	vaccine	and	testing	mandates	may	be	announced	in	jurisdictions	in	which	we	operate	our	business,	and	there	could	be	potential	actions	
by	certain	states	that	are	in	conflict	with	the	federal	mandates,	the	impacts	of	which	remain	uncertain.	Requirements	to	mandate	COVID-19	
vaccination	of	our	workforce	or	requirements	of	our	unvaccinated	employees	to	be	tested	could	result	in	labor	disruptions,	employee	attrition	and	
difficulty	securing	future	labor	needs.

We	continue	to	monitor	developments	involving	our	workforce,	customers,	construction	contractors,	suppliers	and	vendors	and	take	steps	to	
mitigate	against	additional	impacts,	but	given	the	unprecedented	and	evolving	nature	of	these	circumstances,	we	cannot	predict	the	full	extent	of	
the	impact	that	COVID-19	will	have	on	our	operating	results,	financial	condition	and	liquidity.	

Our	strategy	includes	large	capital	investments,	which	are	subject	to	risks.
Our	business	strategy	includes	major	capital	investments	at	our	existing	companies.	Our	capital	investment	program	planned	for	the	next	five	years	
includes	Electric	segment	investments	in	renewable	generation,	transmission	asset	additions	and	upgrades,	and	technology	and	infrastructure	
projects,	and	Manufacturing	and	Plastics	segments	investments	in	facilities,	equipment	and	machinery.	These	capital	projects	are	planned	years	in	
advance	of	their	in-service	dates	and	are	subject	to	various	risks	including:	obtaining	necessary	permits,	licenses	and	approvals	in	a	timely	manner;	
adverse	changes	in	regulatory	treatment	or	public	policy;	changes	in	commodity	pricing,	equipment	and	construction	costs;	technology	changes;	
delivery	delays	of	critical	materials	and	components;	delays	caused	by	construction	accidents,	injuries	or	public	health	crises;	adverse	weather	
conditions;	unforeseen	product	defects;	limited	access	to	capital;	and	other	adverse	conditions.	Capital	investments	in	our	Electric	segment	are	

14

subject	to	regulatory	approval	and	are	at	risk	of	not	being	granted	timely	or	full	recovery	of	our	investments.	The	inability	to	complete	capital	
projects	on	budget	and	in	a	timely	manner	could	adversely	impact	our	operating	results	and	financial	condition.		

Our	acquisition	or	divestiture	strategies	are	subject	to	risk	and	could	adversely	impact	our	financial	position	and	operating	results.	
As	part	of	our	business	strategy,	we	continually	assess	our	mix	of	businesses	and	potential	strategic	acquisitions	or	divestitures.	This	investment	
strategy	is	subject	to	various	risks	including	the	ability	to	identify	appropriate	acquisition	candidates	or	successfully	negotiate	and	finance	any	
acquisitions.	In	addition,	difficulties	in	integrating	the	operations,	services,	products	and	personnel	of	the	acquired	business,	and	the	potential	loss	
of	key	employees,	customers	and	suppliers	of	the	acquired	business	could	adversely	impact	our	financial	condition	and	operating	results.

The	sale	of	any	of	our	businesses	may	result	in	the	recognition	of	a	loss	if	the	business	is	sold	for	less	than	its	book	value	and	may	expose	us	to	risk	
arising	from	indemnification	obligations	that	arose	out	of	the	conduct	of	the	business	prior	to	the	sale.	These	obligations	may	include	warranty	and	
environmental	obligations	or	the	recoverability	of	certain	assets	sold	as	part	of	the	transaction.	Unforeseen	costs	related	to	these	obligations	could	
impact	our	operating	results.

Weather	impacts,	including	normal	seasonal	fluctuation	and	extreme	weather	events,	could	adversely	affect	our	operating	results.
Our	Electric	segment	business	is	seasonal	and	weather	patterns	can	have	a	material	impact	on	our	financial	performance.	Demand	for	electricity	is	
normally	greater	in	the	winter	and	summer	months.	Unusually	mild	summers	and	winters	could	have	an	adverse	effect	on	our	financial	condition	
and	results	of	operations.	Weather	can	also	have	a	significant	impact	on	our	Plastics	segment	businesses	as	most	U.S.	PVC	resin	production	plants	
are	located	in	the	Gulf	Coast	region,	which	is	prone	to	seasonal	hurricane	activity	and	other	extreme	weather	events.	Our	access	to	PVC	resin	may	
be	impacted	by	the	volume	and	magnitude	of	hurricane	and	storm	activity	in	this	region.	In	addition,	our	Plastics	segment	businesses	can	be	
affected	by	weather	prohibiting	or	delaying	construction	projects	at	any	time	of	the	year	in	any	geography,	but	specifically	times	of	the	year	when	
frozen	ground	and	cold	temperatures	in	many	parts	of	the	country	can	delay	construction	projects,	all	of	which	can	result	in	reduced	customer	
demand.

Our	businesses	are	located	in	areas	that	could	be	subject	to	natural	disasters	such	as	severe	snow	and	ice	storms,	tornadoes,	flooding	and	fires.	
These	factors	could	result	in	interruption	of	our	business	and	damage	to	our	facilities.	An	extreme	weather	event	within	our	utility	service	area	
could	directly	affect	our	capital	assets,	causing	disruption	in	service	to	customers	and	result	in	repair	or	replacement	costs,	due	to	downed	wires	
and	poles	or	damage	to	other	operating	equipment.

In	addition	to	variations	in	seasonal	weather	patterns,	more	widespread	climate	change	may	also	create	physical	and	financial	risk	to	our	
businesses.	Physical	risks	of	climate	change,	such	as	more	frequent	or	more	extreme	weather	events,	changes	in	temperature	and	precipitation	
patterns,	changes	to	ground	and	surface	water	availability	and	other	phenomena,	could	affect	some	or	all	of	our	operations.	Severe	weather	or	
other	natural	disasters	related	to	climate	change	could	be	destructive	and	result	in	increased	costs	and	disruptions	in	our	operations.	Extreme	
weather	conditions,	such	as	uncommonly	long	periods	of	high	or	low	ambient	temperature,	generally	require	more	utility	system	backup,	adding	to	
costs	and	contributing	to	increased	system	stress	on	our	utility	infrastructure,	which	could	cause	service	interruptions.	

The	loss	of,	or	significant	reduction	in	revenue	from,	any	of	our	key	customers	could	have	an	adverse	effect	on	our	operating	results.
While	no	single	customer	provided	more	than	10%	of	our	consolidated	operating	revenue,	each	of	our	segments	have	customers	which	accounted	
for	over	10%	of	the	segment’s	operating	revenues.	In	2021,	one	customer	accounted	for	10%	of	Electric	segment	revenue,	three	customers	
combined	to	account	for	46%	of	Manufacturing	segment	operating	revenue	and	two	customers	combined	to	account	for	50%	of	Plastics	segment	
operating	revenue.	The	loss	of	any	one	of	these	customers	or	a	significant	decline	in	sales	to	these	customers,	would	have	a	significant	negative	
impact	on	the	segment's	financial	condition	and	operating	results,	and	could	have	a	significant	negative	impact	on	the	Company’s	consolidated	
financial	condition	and	operating	results.

We	are	subject	to	counterparty	credit	risk.
We	extend	credit	to	our	customers	in	the	ordinary	course	of	business	in	each	of	our	operating	segments.	Our	customers'	ability	to	pay	depends	on	
a	variety	of	factors	including	macroeconomic	conditions,	local	economic	conditions,	including	unemployment	rates,	and	industry	conditions	in	
which	our	commercial	and	industrial	customers	operate.	Increased	customer	delinquencies	and	bad	debts	could	adversely	impact	our	operating	
results	and	liquidity.

A	cyber	incident,	security	breach	or	system	failure	could	adversely	affect	our	business	and	operating	results.
The	operation	of	our	business	is	dependent	on	the	secure	function	of	our	computer	hardware	and	software	systems.	Furthermore,	all	our	
businesses	require	us	to	collect	and	maintain	sensitive	customer	data,	as	well	as	confidential	employee	and	shareholder	information,	which	is	
subject	to	electronic	theft	or	loss.	We	also	use	third-party	vendors	to	electronically	process	certain	of	our	business	transactions.	Information	
systems,	both	ours	and	those	of	third	parties,	are	vulnerable	to	security	breaches	by	computer	hackers	and	cyber	terrorists	and	the	negligent	or	
intentional	breach	of	established	controls	and	procedures	or	mismanagement	of	confidential	information	by	employees.	We	may	also	be	impacted	
by	attacks	and	data	security	breaches	of	financial	institutions,	merchants	or	third-party	processors.	While	we	regularly	conduct	cybersecurity	
assessments,	we	cannot	be	certain	our	information	security	systems	and	protocols	and	those	of	our	vendors	and	other	third	parties	are	sufficient	to	
withstand	a	cyber-attack	or	other	security	breach.

A	major	cyber	incident	could	result	in	significant	expenses	to	investigate	and	repair	security	breaches	or	system	damage	and	could	lead	to	litigation,	
fines,	other	remedial	action,	heightened	regulatory	scrutiny	and	damage	to	our	reputation.	For	example,	we	may	be	subject	to	liability	under	
various	federal,	state	and	international	data	protection	laws.	These	laws	are	subject	to	change	and	expansion	and	may	require	additional	
operational	changes	to	comply.	

The	misappropriation,	corruption	or	loss	of	personally	identifiable	information	and	other	confidential	data	could	lead	to	significant	monetary	
damages,	regulatory	enforcement	actions	and	breach	notification	and	mitigation	expenses,	such	as	credit	monitoring,	and	result	in	reputational	

15

damage	affecting	relations	with	shareholders,	customers	and	regulators.	In	addition	to	property	and	casualty	insurance,	which	may	cover	
restoration	of	data,	certain	physical	damage	or	third-party	injuries,	we	have	cybersecurity	insurance	related	to	a	breach	event.	However,	damage	
and	claims	arising	from	such	incidents	may	not	be	covered	or	may	exceed	the	amount	of	any	available	insurance.

The	inability	to	attract	and	retain	a	qualified	workforce	could	have	an	adverse	effect	on	our	operations.
The	success	of	our	business	is	heavily	dependent	on	the	leadership	of	our	executive	officers	and	key	employees	for	implementation	of	our	strategy.	
In	addition,	all	of	our	businesses	rely	on	technical	employees	who	possess	certain	specialized	knowledge	and	skills.	The	inability	to	attract	and	
maintain	a	skilled	and	stable	workforce	may	negatively	affect	our	ability	to	service	our	customers,	manufacture	products	or	successfully	manage	
our	business	and	achieve	our	objectives.	Competition	for	employees,	including	skilled	workers,	is	high	and	can	lead	to	increased	labor	expenses,	
decreased	productivity	and	potentially	lost	business	opportunities.	Our	ability	to	maintain	productivity,	relationships	with	customers,	competitive	
costs	and	quality	services	is	limited	by	the	ability	to	employ	the	necessary	skilled	personnel	and	could	negatively	affect	our	operating	results,	
financial	condition	and	liquidity.

FINANCIAL	RISKS

We	are	subject	to	capital	market	and	interest	rate	risks.
We	rely	on	access	to	debt	and	equity	capital	markets	as	a	source	of	liquidity	to	fund	our	investment	initiatives,	including	rate	base	growth	
investments	in	our	Electric	segment	and	opportunities	for	investment,	including	acquisitions,	in	our	Manufacturing	and	Plastics	segments.	Capital	
markets	are	impacted	by	global	and	domestic	economic	conditions,	monetary	policy,	commodity	prices,	geopolitical	events	and	other	factors.	If	we	
are	unable	to	access	capital	on	acceptable	terms	and	at	reasonable	costs,	our	ability	to	implement	our	business	plans	may	be	adversely	affected.	In	
addition,	higher	market	interest	rates	on	outstanding	variable-rate,	short-term	indebtedness	could	also	impact	our	operating	results.

A	decrease	in	our	credit	rating	could	increase	our	borrowing	costs	and	result	in	additional	contractual	costs.
We	rely	on	our	investment	grade	credit	ratings	to	provide	acceptable	costs	for	accessing	the	capital	markets.	A	downgrade	of	our	credit	ratings	
could	result	in	higher	borrowing	costs	thereby	negatively	impacting	our	operating	results	and	limiting	our	ability	to	access	capital	markets,	which	
may	negatively	impact	our	ability	to	implement	our	business	plans.	In	addition,	OTP	is	a	party	to	contracts	that	require	the	posting	of	collateral	or	
settlement	of	applicable	contracts	if	credit	ratings	fall	below	certain	levels.	

Our	pension	and	other	postretirement	benefit	plans	are	subject	to	investment	and	interest	rate	risks.
The	financial	obligations	and	related	costs	of	our	pension	and	other	postretirement	benefit	plans	are	affected	by	numerous	factors.	Assumptions	
related	to	future	costs,	investment	returns,	actuarial	estimates	and	interest	rates	have	a	significant	effect	on	our	funding	obligations	and	the	cost	
recognized	for	these	plans.	If	our	pension	plan	assets	do	not	achieve	our	estimated	long-term	rate	of	return	or	if	our	other	estimates	prove	to	be	
inaccurate,	our	operating	results,	financial	condition	and	liquidity	may	be	adversely	impacted.	In	addition,	our	funding	requirements	could	be	
impacted	by	changes	to	the	Pension	Protection	Act.

We	rely	on	our	subsidiaries	to	provide	sufficient	earnings	and	cash	flows	to	allow	us	to	meet	our	financial	obligations	and	pay	dividends	to	our	
shareholders.	
OTC	is	a	holding	company	with	no	significant	operations	of	its	own.	The	primary	source	of	funds	for	payment	of	our	financial	obligations	and	
dividends	to	our	shareholders	is	from	cash	provided	by	our	subsidiary	companies.	Our	ability	to	meet	our	financial	obligations	and	pay	dividends	on	
our	common	stock	principally	depends	on	the	earnings,	cash	flows,	capital	requirements	and	general	financial	positions	of	our	subsidiary	
companies.	In	addition,	OTP	is	subject	to	federal	and	state	regulations	which	may	restrict	its	ability	to	pay	dividends.	Finally,	we	are	also	reliant	on	
our	subsidiary	companies	to	maintain	compliance	with	financial	covenants	under	our	various	short-	and	long-term	debt	agreements.	Our	debt	
agreements	include	restrictions	on	the	payment	of	cash	dividends	upon	an	event	of	default.	

Changes	in	tax	laws	could	materially	affect	our	financial	condition	and	operating	results.
Our	provision	for	income	taxes	and	tax	obligations	are	impacted	by	various	tax	laws	and	regulations,	including	the	availability	of	various	tax	credits,	
IRS	tax	policies	such	as	tax	normalization	and,	at	times,	the	ability	to	carryforward	net	operating	losses	and	tax	credits.	Changes	in	tax	laws,	
regulations	and	interpretations	could	have	an	adverse	effect	on	our	financial	condition	and	operating	results.	Tax	law	changes	that	reduce	or	
eliminate	production	or	investment	tax	credits	may	impact	the	economics	of	constructing	certain	electric	generation	resources,	which	may	
adversely	impact	our	planned	investments.		

A	significant	impairment	of	our	goodwill	would	negatively	impact	our	financial	position	and	operating	results.
As	of	December	31,	2021,	we	had	$37.6	million	of	goodwill	recorded	on	our	consolidated	balance	sheet.	We	have	recorded	goodwill	for	businesses	
in	our	Manufacturing	and	Plastics	segments.	Goodwill	is	tested	for	impairment	annually	or	whenever	events	or	changes	in	circumstances	indicate	
impairment	may	have	occurred.	The	goodwill	impairment	test	requires	us	to	estimate	the	fair	value	of	the	businesses	being	tested.	Estimating	the	
fair	value	of	a	business	unit	requires	significant	judgments	and	estimates,	including	estimates	of	future	operating	results	and	cash	flows,	among	
others.	These	estimates	can	be	affected	by	numerous	factors,	including	changes	in	economic,	industry	or	market	conditions,	changes	in	business	
operations,	changes	in	competition	or	changes	in	technologies.	Any	changes	in	key	assumptions	or	material	differences	between	actual	and	
forecasted	financial	performance	could	affect	our	fair	value	estimates	and	lead	to	a	goodwill	impairment	charge	that	could	adversely	affect	our	
financial	condition	and	operating	results,	as	well	as	impact	compliance	with	financing	agreement	covenants.	

ELECTRIC	SEGMENT	RISKS

General	economic	and	industry	conditions	impact	our	business.
Several	factors,	many	of	which	are	beyond	our	control,	may	contribute	to	reduced	demand	for	energy	from	our	customers	or	increase	the	cost	of	
providing	energy	to	our	customers.	These	risks	include	economic	growth	or	decline	in	our	service	areas,	demographic	changes	in	our	customer	base	
and	changes	in	customer	demand	or	load	growth	due	to,	among	other	items,	proliferation	of	distributed	generation,	energy	efficiency	initiatives	

16

and	technological	advancements.	In	addition,	customer	demand	could	be	impacted	by	increased	competition	in	our	service	territories	or	the	loss	of	
a	service	territory	or	franchise.	Other	risks	include	increased	transmission	or	interconnection	costs,	generation	curtailment	and	changes	in	the	
manner	in	which	wholesale	power	is	purchased	and	sold.	A	decrease	in	revenues	or	an	increase	in	expenses	related	to	our	electric	operations	could	
negatively	impact	our	financial	condition,	operating	results	and	liquidity.

Our	utility	business	is	significantly	impacted	by	government	legislation	and	regulation.
OTP	is	subject	to	federal	and	state	legislation	and	comprehensive	regulation	by	federal	and	state	regulatory	agencies,	including	the	public	utility	
commissions	in	each	of	the	three	states	in	which	OTP	operates,	and	by	the	FERC.	State	utility	commissions	regulate,	among	other	matters,	the	
establishment	of	assigned	service	areas,	the	siting	and	construction	of	major	facilities,	the	capital	structure	of	the	utility	business	and	the	allowed	
rates	to	charge	customers	for	providing	energy	and	utility	service.	Each	state	utility	commission	operates	independent	of	one	another;	therefore,	
OTP	is	subject	to	and	must	adhere	to	the	decisions	of	each	independent	state	commission.	The	FERC	regulates,	among	other	matters,	wholesale	
energy	transactions,	hydroelectric	licensing,	transmission	and	sale	of	electric	energy	in	interstate	commerce	and	the	interconnection	of	electric	
facilities.	

Our	financial	condition,	operating	results	and	liquidity	are	significantly	impacted	by	and	dependent	upon	our	ability	to	recover	the	cost	of	providing	
utility	service	and	earning	a	return	on	our	utility	capital	investments.	There	is	no	assurance	that	each	state	utility	commission	will	judge	our	utility	
costs	to	have	been	prudently	incurred	or	that	rates	will	produce	full	recovery	of	such	costs.	In	addition,	there	could	be	changes	in	the	federal	or	
state	regulatory	framework	that	would	impair	our	ability	to	recover	utility	costs	historically	collected	from	our	customers.	In	addition,	inflationary	
cost	pressures	could	increase	the	cost	of	constructing	our	utility	assets	and	operating	our	utility	business.	Rising	fuel	costs	could	increase	the	cost	of	
providing	energy	to	our	customers.	In	each	instance,	there	can	be	no	assurance	that	our	state	regulatory	commissions	will	authorize	recovery	of	
these	rising	costs.	In	addition	to	the	recovery	of	our	utility	costs,	our	profitability	is	impacted	by	the	authorized	return	on	equity,	which	can	be	
impacted	by	macroeconomic	factors	such	as	interest	rates.	There	can	be	no	assurance	that	our	state	utility	commissions	or	the	FERC	will	authorize	
an	acceptable	rate	of	return.

An	adverse	decision	by	one	or	more	regulatory	authorities	concerning	the	level	or	method	of	determining	electric	utility	rates,	the	authorized	
returns	on	equity,	recoverability	of	fuel,	purchase	power	and	other	costs,	the	allocation	of	costs	between	jurisdictions,	approval	of	depreciation	
rates,	implementation	of	enforceable	federal	reliability	standards	or	other	regulatory	matters,	permitted	business	activities,	such	as	ownership	or	
operation	of	nonelectric	businesses,	or	any	prolonged	delay	in	rendering	a	decision	in	a	rate	or	other	proceeding	could	adversely	impact	our	
financial	condition,	operating	results	and	liquidity.

Our	generating	facilities	are	subject	to	risks	that	could	result	in	early	closure	or	a	sale	of	our	interest.		
Changes	in	operational	or	economic	factors,	environmental	regulation	or	risks	of	litigation	could	result	in	the	early	closure	of,	or	the	sale	of	our	
interest	in,	a	generating	facility.	In	the	event	of	an	early	closure,	a	significant	asset	impairment	charge	could	be	required	and	we	would	be	obligated	
to	pay	for	costs	of	closure	for	our	share	of	the	generating	facility,	including	costs	associated	with	decommissioning,	remediation,	reclamation	and	
restoration	of	the	property,	and	any	costs	of	terminating	contracts	associated	with	the	generating	facility,	such	as	coal	supply	arrangements.	In	the	
event	of	a	sale	of	our	interest	in	a	generating	facility,	we	may	not	be	able	to	negotiate	the	sale	on	favorable	terms,	which	could	result	in	the	
recognition	of	a	loss	on	the	sale	and	other	potential	liabilities.	There	can	be	no	assurance	that	we	would	be	authorized	by	any	or	all	of	our	state	
utility	commissions	to	recover	any	costs	or	losses	associated	with	the	early	closure	of	or	sale	of	our	interest	in	a	generating	facility.

The	loss	of	a	major	generating	facility	would	require	OTP	to	identify	and	receive	approval	for	other	sources	of	generation	for	its	customers,	if	
available,	and	expose	it	to	higher	purchased	power	costs.	In	addition,	OTP	may	not	be	able	to	obtain	timely	regulatory	approval	for	new	generation	
resources	to	replace	closed	facilities.

In	September	2021,	our	IRP	filed	in	the	three	jurisdictions	in	which	we	operate	outlined	our	plan	to	withdraw	from	our	35	percent	ownership	
interest	in	Coyote	Station,	a	jointly	owned	coal	fired	generation	plant,	by	December	31,	2028.	We	will	seek	to	recover	all	costs	related	to	the	future	
withdrawal	from	Coyote	Station,	however,	there	can	be	no	assurance	that	we	will	be	granted	recovery	of	any	or	all	such	costs.	A	full	or	partial	
denial	of	recovery	of	the	costs	of	withdrawal	could	significantly	impact	our	operating	results,	financial	condition	and	liquidity.

Federal	and	state	environmental	regulation	could	require	us	to	incur	substantial	capital	expenditures	and	increased	operating	costs	or	make	it	
no	longer	economically	viable	to	operate	some	of	our	facilities.
We	are	subject	to	federal,	state	and	local	environmental	laws	and	regulations	relating	to	air	quality,	water	quality,	waste	management,	natural	
resources	and	health	safety.	These	laws	and	regulations	regulate	the	modification	and	operation	of	existing	facilities,	the	construction	and	
operation	of	new	facilities	and	the	proper	storage,	handling,	cleanup	and	disposal	of	hazardous	waste	and	toxic	substances.	Compliance	with	these	
legal	requirements	requires	us	to	commit	significant	resources	and	funds	toward	environmental	monitoring,	installation	and	operation	of	pollution	
control	equipment,	payment	of	emission	fees	and	securing	environmental	permits.	Obtaining	environmental	permits	can	entail	significant	expense	
and	cause	substantial	construction	delays.	Failure	to	comply	with	environmental	laws	and	regulations,	even	if	caused	by	factors	beyond	our	control,	
may	result	in	civil	or	criminal	liabilities,	penalties	and	fines.

Coyote	Station,	one	of	OTP's	jointly	owned	coal	fired	power	plant,	is	subject	to	assessment	under	the	second	implementation	period	of	RHR	as	part	
of	the	state	of	North	Dakota's	state	implementation	plan.	We	cannot	predict	with	certainty	the	impact	the	state	implementation	plan	may	have	on	
our	business	until	the	plan	has	been	approved	or	otherwise	acted	on	by	the	EPA.	However,	significant	emission	control	investments	could	be	
required.	Alternatively,	investments	in	emission	control	equipment	may	prove	to	be	uneconomic	and	result	in	an	early	closure	of,	or	the	sale	of	our	
interest	in,	Coyote	Station.	

Existing	environmental	laws	or	regulations	may	be	revised,	and	new	laws	or	regulations	may	be	adopted	or	become	applicable	to	us.	The	multiple	
jurisdictions	that	govern	our	electric	utility	business	may	not	agree	as	to	the	appropriate	resource	mix,	which	may	lead	to	costs	to	comply	with	one	
jurisdiction	that	are	not	recoverable	across	all	jurisdictions	served	by	the	same	assets.	Revised	or	additional	regulations,	which	result	in	increased	

17

compliance	costs	or	additional	operating	restrictions,	particularly	if	those	costs	are	not	fully	recoverable	from	customers,	could	have	a	material	
effect	on	our	operating	results	and	make	it	no	longer	economically	viable	to	operate	some	of	our	facilities.

Legislation,	regulation,	litigation	or	other	actions	related	to	climate	change	and	greenhouse	gas	emissions	could	materially	impact	us.
Current	and	future	federal,	state,	regional	and	international	regulations	to	address	global	climate	change	and	reduce	GHG	emissions,	including	
measures	such	as	mandated	levels	of	renewable	generation,	mandatory	reductions	in	CO2	emission	levels,	taxes	on	CO2	emissions	or	cap-and-trade	
regimes,	could	require	us	to	incur	significant	costs,	which	could	negatively	impact	our	financial	condition,	operating	results	and	liquidity	if	such	
costs	cannot	be	recovered	through	rates	granted	by	ratemaking	authorities	or	through	increased	market	prices	for	electricity.	

In	2021,	the	Biden	Administration	introduced	new	targets	aimed	at	reducing	economy-wide	net	GHG	emissions	by	50	to	52	percent	from	2005	
levels	by	2030.	In	addition,	the	Administration	set	a	goal	to	reach	100	percent	carbon	pollution-free	electricity	by	2035.	To	achieve	these	targets	the	
Administration	may	implement	new	regulations	targeting	GHG	emissions	from	existing	fossil	fuel-fired	power	plants.	While	the	precise	nature	and	
implications	of	any	new	regulations	are	uncertain,	such	regulations	could	impose	substantial	costs	on	and	impact	the	operations	of	our	utility	
business,	which	may	materially	impact	our	financial	condition,	operating	results	and	liquidity.

In	addition	to	complying	with	legislation	and	regulation,	we	could	be	subject	to	litigation	related	to	climate	change.	Costs	of	such	litigation	could	be	
significant,	and	an	adverse	outcome	could	require	substantial	capital	expenditures,	changes	in	operations	and	possible	payment	of	penalties	or	
damages	which	could	affect	our	operating	results	and	liquidity	if	the	costs	are	not	recoverable	in	rates	or	covered	by	insurance.	

To	the	extent	investors	view	climate	change,	fossil	fuel	combustion	and	GHG	emissions	as	a	financial	risk,	our	stock	price	or	our	ability	to	access	
capital	markets	on	favorable	terms	and	conditions	could	be	adversely	impacted.

Violations	of	extensive	legal	and	regulatory	compliance	requirements	could	have	a	negative	impact	on	our	business	and	results	of	operations.
We	are	subject	to	an	extensive	legal	and	regulatory	framework	imposed	under	federal	and	state	laws	and	regulatory	agencies,	including	the	FERC	
and	the	NERC.	We	could	be	subject	to	potential	financial	penalties	for	compliance	violations.	Our	transmission	systems	and	electric	generation	
facilities	are	subject	to	the	NERC	mandatory	reliability	standards,	including	cybersecurity	standards.	If	a	serious	reliability	incident	did	occur,	it	could	
have	a	material	effect	on	our	operations	or	financial	results.	Some	states	have	the	authority	to	impose	substantial	penalties	in	the	event	of	non-
compliance.	We	attempt	to	mitigate	the	risk	of	regulatory	penalties	through	formal	training.	However,	there	is	no	guarantee	our	compliance	
program	will	be	sufficient	to	ensure	against	violations.

In	addition,	energy	policy	initiatives	at	the	state	or	federal	level	could	increase	incentives	for	distributed	generation	or	authorize	municipal	utility	
formation	or	acquisition	of	service	territory,	or	local	initiatives	could	introduce	generation	or	distribution	requirements	that	could	change	the	
current	integrated	utility	model.

These	laws	and	regulations	significantly	influence	our	operations	and	may	affect	our	ability	to	recover	costs	from	our	customers.	We	are	required	
to	have	numerous	permits,	licenses,	approvals	and	certificates	from	the	agencies	and	other	organizations	that	regulate	our	business.	We	believe	we	
have	obtained	the	necessary	approvals	for	our	existing	operations	and	that	our	business	is	conducted	in	accordance	with	applicable	laws	and	
regulatory	requirements;	however,	we	are	unable	to	predict	the	impact	on	our	operating	results	from	the	future	regulatory	activities	of	any	of	
these	agencies	and	other	organizations.	Changes	in	regulations	or	the	imposition	of	additional	regulations	could	have	a	material	adverse	impact	on	
our	results	of	operations.

Our	transmission	and	generation	facilities	could	be	vulnerable	to	cyber	and	physical	attack.
OTP	owns	electric	transmission	and	generation	facilities	subject	to	mandatory	and	enforceable	standards	advanced	by	the	NERC.	These	bulk	electric	
system	facilities	provide	the	framework	for	the	electrical	infrastructure	of	OTP’s	service	territory	and	interconnected	systems,	the	operation	of	
which	is	dependent	on	information	technology	systems.	Further,	the	information	systems	that	operate	OTP’s	electric	system	are	interconnected	to	
external	networks.	Parties	that	wish	to	disrupt	the	U.S.	bulk	power	system	or	OTP’s	operations	could	view	OTP’s	computer	systems,	software	or	
networks	as	attractive	targets	for	cyber-attack.

In	addition,	OTP’s	generation	and	transmission	facilities	are	spread	throughout	a	large	service	territory.	These	facilities	could	be	subject	to	physical	
attack	or	vandalism	that	could	disrupt	OTP’s	operations	or	conceivably	the	regional	or	U.S.	bulk	power	system.

OTP	is	subject	to	mandatory	cybersecurity	and	physical	security	regulatory	requirements.	OTP	implements	the	NERC	standards	for	operating	its	
transmission	and	generation	assets	and	stays	abreast	of	best	practices	within	business	and	the	utility	industry	to	protect	its	computers	and	
computer-controlled	systems	from	outside	attack.	We	rely	on	industry	accepted	security	measures	and	technology	to	securely	maintain	
confidential	and	proprietary	information	necessary	for	the	operation	of	our	systems.	In	an	effort	to	reduce	the	likelihood	and	severity	of	cyber	
intrusions,	we	have	cybersecurity	processes	and	controls	and	disaster	recovery	plans	designed	to	protect	and	preserve	the	confidentiality,	integrity	
and	availability	of	data	and	systems.	We	also	take	prudent	and	reasonable	steps	to	protect	the	physical	security	of	our	generation	and	transmission	
facilities.	However,	all	these	measures	and	technology	may	not	adequately	prevent	security	breaches,	ransomware	attacks	or	other	cyber-attacks	
or	enable	us	to	recover	effectively	from	such	a	breach	or	attack.	Any	significant	interruption	or	failure	of	our	information	systems	or	any	significant	
breach	of	security	due	to	cyber-attacks,	hacking	or	internal	security	breaches	or	physical	attack	of	our	generation	or	transmission	facilities	could	
adversely	affect	our	business	and	results	of	operations.

Our	generating	facilities	are	subject	to	operational	risks	that	could	result	in	unscheduled	plant	outages	and	increased	costs.
The	operation	of	electric	generating	facilities	involves	many	risks,	including	facility	shutdowns	due	to	equipment	or	process	failures;	labor	disputes;	
operator	error;	catastrophic	events	such	as	fires,	explosions	and	floods;	the	dependence	on	a	specific	fuel	source;	and	the	risk	of	performance	
below	expected	levels	of	output	or	efficiency.	We	could	be	subject	to	costs	associated	with	any	unexpected	failure	to	produce	or	deliver	power,	
including	failures	caused	by	a	breakdown	or	forced	outage,	as	well	as	damages	to	facilities.

18

We	rely	on	a	limited	number	of	suppliers	to	provide	coal	and	coal	transportation	to	our	facilities.	A	failure	to	perform	by	any	of	these	
counterparties	may	arise	due	to	liquidity	challenges	or	insolvency,	operational	deficiencies	or	other	circumstances	such	as	severe	weather	or	
natural	disasters,	which	could	impact	our	ability	to	provide	service	to	our	customers	or	require	us	to	seek	alternative	sources	for	these	products	
and	services,	if	available,	which	could	lead	to	increased	costs	adversely	impacting	our	operating	results.	

Joint	ownership	of	coal-fired	generation	facilities	could	impact	our	ability	to	manage	changing	regulations	and	economic	conditions.
We	own	our	coal-fired	generation	facilities	jointly	with	other	co-owners	with	varying	ownership	interests	in	such	facilities.	Our	ability	to	make	
determinations	on	our	integrated	resource	plan	in	order	to	best	navigate	changing	environmental	regulations	and	economic	conditions	may	be	
impacted	by	our	rights	and	obligations	under	the	co-ownership	agreements	and	related	agreements	and	our	ability	to	reconcile	a	divergence	in	the	
interests	of	OTP	and	the	co-owners	of	these	generation	facilities.	Such	a	divergence	could	impair	our	ability	to	effectively	manage	these	changing	
conditions	to	meet	our	strategic	objectives	and	could	adversely	impact	our	financial	condition,	operating	results	and	liquidity.	

We	are	subject	to	risks	associated	with	energy	markets.
Our	electric	business	is	subject	to	the	risks	associated	with	energy	markets,	including	market	supply	and	changing	energy	prices.	If	we	are	faced	
with	shortages	in	market	supply,	we	may	be	unable	to	fulfill	our	contractual	obligations	to	our	retail,	wholesale	and	other	customers	at	previously	
anticipated	costs.	This	could	force	us	to	obtain	alternative	energy	or	fuel	supplies	at	higher	costs	or	suffer	increased	liability	for	unfulfilled	
contractual	obligations.	Any	significantly	higher	than	expected	energy	or	fuel	costs	could	negatively	affect	our	financial	performance.

MANUFACTURING	SEGMENT	RISKS

The	price	and	availability	of	raw	materials	could	adversely	impact	our	operating	results.
The	companies	in	our	Manufacturing	segment	use	a	variety	of	raw	materials	in	the	products	they	manufacture	including,	among	others,	steel,	
aluminum,	and	polystyrene	and	other	plastics	resins.	The	price	and	availability	of	the	raw	materials	used	in	our	manufacturing	process	are	based	on	
global	supply	and	demand	conditions,	which	can	create	volatile	pricing	and	supply	disruptions	as	conditions	change.	Federal	trade	policies,	
including	imposed	tariffs,	can	also	impact	prices	for	these	raw	materials.	If	we	are	unable	to	pass	cost	increases	on	to	our	customers	or	are	unable	
to	procure	adequate	or	timely	raw	material	inputs	for	use	in	our	manufacturing	processes,	our	operating	results	could	be	negatively	impacted.	

Additionally,	a	certain	amount	of	residual	material	(scrap)	is	a	by-product	of	the	manufacturing	and	production	processes	used	by	our	
manufacturing	companies.	Declines	in	commodity	prices	for	these	scrap	materials	due	to	weakened	demand	or	excess	supply	can	negatively	impact	
the	profitability	of	our	manufacturing	companies	as	it	reduces	their	ability	to	mitigate	the	cost	associated	with	excess	material.	

Competition	from	foreign	and	domestic	manufacturers	could	affect	the	revenues	and	earnings	of	our	manufacturing	businesses.
Our	manufacturing	businesses	are	subject	to	intense	competition	from	foreign	and	domestic	manufacturers,	many	of	whom	have	broader	product	
lines,	greater	distribution	capabilities,	greater	capital	resources,	larger	marketing,	research	and	development	personnel	and	facilities,	and	other	
capabilities.	Our	ability	to	compete	on	product	performance,	competitive	pricing,	technological	innovation	and	customer	service	is	critical	to	our	
ongoing	success.	If	we	are	unable	to	compete	in	these	and	potentially	other	areas,	our	business	and	operating	results	could	be	adversely	impacted.		

Economic	conditions	in	the	end	markets	in	which	our	customers	operate	could	have	an	adverse	impact	on	our	operating	results	and	liquidity.
Our	manufacturing	businesses	derive	a	large	amount	of	their	revenues	from	customers	in	the	following	industry	sectors:	recreational	vehicle/
powersports,	lawn	and	garden,	construction,	agriculture,	energy	and	horticultural.	Factors	affecting	any	of	these	industries	in	general	could	
adversely	affect	our	operating	results	as	growth	in	our	operating	revenues	is	largely	dependent	on	the	growth	of	our	customers’	businesses	in	their	
respective	industries.	These	factors	include:

•

•

•

•

•

•

seasonality	of	demand	for	our	customers’	products,	which	may	cause	our	manufacturing	capacity	to	be	underutilized	for	periods	of	time;

our	customers’	failure	to	successfully	market	their	products,	gain	or	retain	widespread	commercial	acceptance	of	their	products	or	
compete	effectively	in	their	industries;

loss	of	market	share	for	our	customers’	products,	which	may	lead	our	customers	to	reduce	or	discontinue	purchasing	our	products	and	
components	and	to	reduce	prices,	thereby	exerting	pricing	pressure	on	us;

economic	conditions	in	the	markets	in	which	our	customers	operate;	in	particular,	the	United	States,	including	recessionary	periods	such	
as	a	global	economic	downturn;

our	customers’	decision	to	bring	the	production	of	components	in-house	that	has	traditionally	been	outsourced	to	us;	and

product	design	changes	or	manufacturing	process	changes	that	may	reduce	or	eliminate	demand	for	the	components	we	supply.

We	expect	future	sales	will	continue	to	depend	on	the	success	of	our	customers.	If	economic	conditions	or	demand	for	our	customers’	products	
deteriorate,	we	may	experience	a	material	adverse	effect	on	our	business,	operating	results	and	financial	condition.

Our	business	may	be	adversely	affected	if	we	are	not	able	to	maintain	our	workforce	and	manufacturing,	engineering	and	technological	
expertise.
The	markets	for	our	manufacturing	businesses	are	characterized	by	changing	technology	and	evolving	process	development.	The	continued	success	
of	our	businesses	will	depend	on	our	ability	to:

•

•

•

•

hire,	retain	and	expand	our	workforce,	including	qualified	engineering	and	trade-skilled	personnel;

maintain	technological	leadership	in	our	industry;

implement	new	and	expand	on	current	robotics,	automation	and	tooling	technologies;	and

anticipate	or	respond	to	changes	in	manufacturing	processes	in	a	cost-effective	and	timely	manner.

19

We	may	be	unable	to	develop	the	capabilities	required	by	our	customers	in	the	future.	The	emergence	of	new	technologies,	industry	standards	or	
customer	requirements	may	render	our	equipment,	inventory	or	processes	obsolete	or	noncompetitive.	We	may	be	required	to	acquire	new	
technologies	and	equipment	to	remain	competitive.	The	acquisition	and	implementation	of	new	technologies	and	equipment	may	require	us	to	
incur	significant	expense	and	capital	investment,	which	could	reduce	our	margins	and	affect	our	operating	results.	When	we	establish	or	acquire	
new	facilities,	we	may	not	be	able	to	maintain	or	develop	our	manufacturing,	engineering	and	technological	expertise	due	to	a	lack	of	trained	
personnel,	effective	training	of	new	staff	or	technical	difficulties	with	machinery.	Failure	to	anticipate	and	adapt	to	customers’	changing	
technological	needs	and	requirements,	to	hire	and	retain	a	sufficient	number	of	engineers	and	trade-skilled	personnel,	and	to	maintain	
manufacturing,	engineering	and	technological	expertise	may	have	a	material	adverse	effect	on	our	businesses	and	operating	results.

Our	manufacturing	operations	are	subject	to	environmental,	health	and	safety	laws	and	regulations	that	could	result	in	liabilities	to	us.	
Our	manufacturing	operations,	which	include	painting	and	coating	processes,	are	subject	to	environmental,	health	and	safety	laws	and	regulations,	
including	those	governing	discharges	to	air	and	water,	the	management	and	disposal	of	hazardous	substances,	the	cleanup	of	contaminated	sites	
and	health	and	safety	matters.	We	could	be	required	to	incur	material	costs,	including	cleanup	costs,	civil	and	criminal	fines,	penalties	and	third-
party	claims	for	cost	recovery,	property	damage	or	personal	injury	as	a	result	of	violations	of	or	liabilities	under	such	laws	and	regulations.	The	
ultimate	cost	of	remediating	contaminated	sites,	if	any,	is	difficult	to	accurately	predict	and	could	exceed	estimates.	In	addition,	as	environmental,	
health	and	safety	laws	and	regulations	have	become	more	strict,	we	could	incur	additional	costs	complying	with	requirements	that	are	
promulgated	in	the	future.

PLASTICS	SEGMENT	RISKS

Changes	in	PVC	resin	prices	could	negatively	affect	our	plastics	business.
The	PVC	pipe	industry	is	highly	sensitive	to	commodity	raw	material	pricing	volatility.	Historically,	when	resin	prices	are	rising	or	stable,	margins	and	
sales	volume	have	been	higher	and	when	resin	prices	are	falling,	sales	volumes	and	margins	have	been	lower.	Changes	in	PVC	resin	prices	can	
negatively	affect	PVC	pipe	prices,	profit	margins	on	PVC	pipe	sales	and	the	value	of	our	finished	goods	inventory.

Our	plastics	operations	are	highly	dependent	on	a	limited	number	of	vendors	and	a	limited	supply	of	PVC	resin	and	other	materials.
We	rely	on	a	limited	number	of	vendors	to	supply	the	PVC	resin	used	in	our	plastics	business.	In	2021	we	sourced	all	of	our	PVC	resin	needs	from	
two	vendors.	In	addition,	the	supply	of	PVC	resin	may	be	limited	primarily	due	to	manufacturing	capacity	and	the	limited	availability	of	raw	material	
components.	Most	U.S.	resin	production	plants	are	located	in	the	Gulf	Coast	region.	This	could	increase	the	risk	of	a	shortage	of	resin	in	the	event	
of	a	hurricane,	other	extreme	weather	events	and	other	natural	disasters	in	that	region.	The	loss	of	a	key	vendor	or	any	interruption	or	delay	in	the	
availability	or	supply	of	PVC	resin	could	disrupt	our	ability	to	deliver	our	plastic	products,	cause	customers	to	cancel	orders	or	require	us	to	incur	
additional	expenses	to	obtain	PVC	resin	from	alternative	sources,	if	such	sources	are	available.

Although	PVC	resin	is	the	most	significant	raw	material	input	in	our	PVC	pipe	manufacturing	process,	we	do	use	certain	other	materials,	such	as	
stabilizers,	gaskets	and	others,	in	the	process	of	manufacturing	and	shipping	our	PVC	pipe	products.	We	generally	source	these	materials	from	a	
limited	number	of	suppliers	and	any	significant	supply	chain	constraints	or	disruptions	related	to	these	materials	could	also	disrupt	our	ability	to	
manufacture	or	ship	products	and	could	result	in	increased	costs.

We	compete	against	many	other	manufacturers	of	PVC	pipe	and	manufacturers	of	alternative	products.	Customers	may	not	distinguish	our	
products	from	those	of	our	competitors.
The	plastic	pipe	industry	is	fragmented	and	competitive	due	to	the	number	of	producers	and	the	fungible	nature	of	the	product.	We	compete	not	
only	against	other	plastic	pipe	manufacturers,	but	also	against	ductile	iron,	steel	and	concrete	pipe	manufacturers.	Due	to	shipping	costs,	
competition	is	usually	regional	instead	of	national	in	scope	and	the	principal	areas	of	competition	are	a	combination	of	price,	service,	warranty	and	
product	performance.	Our	inability	to	compete	effectively	in	each	of	these	areas	and	to	distinguish	our	plastic	pipe	products	from	competing	
products	may	adversely	affect	the	financial	performance	of	our	plastics	business.

External	factors	beyond	our	control	could	cause	fluctuations	in	demand	for	our	PVC	pipe	products	and	changes	in	our	prices	and	margins,	which	
could	adversely	impact	our	operating	results.
Our	PVC	pipe	products,	sold	through	distributors	and	wholesalers,	are	primarily	used	in	municipal	and	rural	water	projects,	wastewater	projects,	
storm	drainage	systems	and	reclamation	systems.	External	factors	beyond	our	control	can	cause	volatility	in	raw	material	prices,	demand	for	our	
products,	prices	of	our	product	and	volumes	and	deterioration	in	operating	margins.	These	factors	can	magnify	the	impact	of	economic	cycles	on	
our	business	and	results	of	operations.		Examples	of	external	factors	include:

•

•

•

•

•

•

general	economic	conditions	including	housing	and	construction	markets	which	can	be	cyclical;

increases	in	interest	rates;

severe	weather	and	natural	disasters;

governmental	regulation	in	the	United	States;

funding	shortages	for	municipal	water	and	wastewater	projects	can	also	adversely	impact	demand	for	our	products;	and

pandemics	and	other	public	health	threats.	

GENERAL	RISK	FACTORS

Economic	conditions	could	negatively	impact	our	businesses.
Our	businesses	are	affected	by	local,	national	and	worldwide	economic	conditions,	including	the	impact	of	inflation,	tightening	of	credit	in	financial	
markets,	economic	recessions	or	other	changes	in	economic	conditions.	Our	businesses	may	be	adversely	affected	by	decreases	in	the	general	level	
of	economic	activity,	such	as	decreases	in	business	and	consumer	spending.	A	decline	in	the	level	of	economic	activity	and	uncertainty	regarding	

20

energy	and	commodity	prices	could	adversely	affect	our	results	of	operations	and	our	future	growth.	Inflationary	pressures	may	lead	to	rising	
material	and	commodity	costs	and	increased	labor	costs.	Our	operating	results	and	liquidity	would	be	adversely	impacted	if	we	were	unable	to	
recover	these	increased	costs	from	our	customers.	Tightening	of	credit	in	financial	markets	could	adversely	affect	the	ability	of	customers	to	
finance	purchases	of	our	goods	and	services,	resulting	in	decreased	orders,	cancelled	or	deferred	orders,	slower	payment	cycles,	and	increased	bad	
debt	and	customer	bankruptcies.	

If	we	are	unable	to	achieve	the	organic	growth	we	expect,	our	financial	performance	may	be	adversely	affected.
We	expect	much	of	our	growth	in	the	next	few	years	will	come	from	major	capital	investment	at	existing	companies.	To	achieve	the	organic	growth	
we	expect,	we	must	have	access	to	the	capital	markets,	be	successful	with	capital	expansion	programs	related	to	organic	growth,	develop	new	
products	and	services,	expand	our	markets	and	increase	efficiencies	in	our	businesses.	Competitive	and	economic	factors	could	adversely	affect	our	
ability	to	do	this.	If	we	are	unable	to	achieve	and	sustain	consistent	organic	growth,	we	will	be	less	likely	to	meet	our	earnings	growth	targets,	
which	may	adversely	affect	the	market	price	of	our	common	shares.

ITEM	7. MANAGEMENT'S	DISCUSSION	AND	ANALYSIS	OF	FINANCIAL	CONDITION	AND	RESULTS	OF	OPERATIONS

You	should	read	the	following	discussion	and	analysis	of	our	financial	condition	and	results	of	operations	together	with	our	financial	statements	and	the	related	notes	
appearing	under	Item	8	of	this	Form	10-K.

OVERVIEW

Otter	Tail	Corporation	(OTC)	and	its	subsidiaries	form	a	diverse	group	of	businesses	with	operations	classified	into	three	segments:	Electric,	
Manufacturing	and	Plastics.	Our	Electric	business	is	a	vertically	integrated,	regulated	utility	with	generation,	transmission	and	distribution	facilities	
to	serve	our	customers	in	western	Minnesota,	eastern	North	Dakota	and	northeastern	South	Dakota.	Our	Manufacturing	segment	provides	metal	
fabrication	for	custom	machine	parts	and	metal	components	and	manufactures	extruded	and	thermoformed	plastic	products.	Our	Plastics	segment	
manufactures	PVC	pipe	for	use	in,	among	other	applications,	municipal	and	rural	water,	wastewater	and	water	reclamation	projects.

Our	strategy	includes	investing	in	rate	base	growth	opportunities	in	our	Electric	segment	and	capitalizing	on	organic	growth	opportunities	in	our	
Manufacturing	and	Plastics	segments.	Investments	in	our	Electric	segment	are	expected	to	produce	increased	earnings	and	cash	flow	potential	and	
lower	our	overall	risk,	create	a	more	predictable	earnings	stream,	improve	our	credit	quality	and	preserve	our	ability	to	fund	our	dividend.	Our	
Electric	segment	is	complemented	by	our	Manufacturing	and	Plastics	segment	businesses,	which	we	expect	to	contribute	to	earnings	growth	by	
capitalizing	on	market	expansion	opportunities	and	increasing	utilization	of	existing	capacities	and	planned	investments	to	create	additional	
capacity	and	increased	efficiencies.	Collectively,	our	mix	of	businesses	is	expected	to	contribute	to	the	achievement	of	our	targeted	annual	growth	
in	earnings	per	share	of	five	to	seven	percent	over	the	next	several	years,	using	2020	as	the	base	for	measurement.

OTTREEINasdaq201620172018201920202021$100$150$200$250In	2021,	all	of	our	businesses	were	able	to	effectively	manage	through	the	challenges	resulting	from	the	COVID-19	pandemic	and	other	marketplace	
challenges,	including	supply	chain	disruptions	and	rapidly	escalating	costs	for	certain	raw	material	components	used	in	our	manufacturing	
processes.	We	continue	to	remain	focused	on	maintaining	the	health	and	safety	of	our	employees,	customers	and	communities	and	ensuring	
continued	electrical	reliability	and	continuous	delivery	of	our	products	to	our	customers.

2021	FINANCIAL	RESULTS
Our	Electric	segment	produced	earnings	growth	of	8.5%	in	2021,	driven	by	returns	on	our	recent	rate	base	investments.	Our	Merricourt	wind	farm	
and	Astoria	Station	natural	gas	plant,	which	collectively	constitute	a	$420	million	investment,	were	completed	and	placed	in	service	in	the	fourth	
quarter	of	2020	and	the	first	quarter	of	2021,	respectively.	Recovery	of	these	investments	and	associated	operating	costs	through	either	rate	riders	
or	interim	rates	provided	under	our	Minnesota	rate	case	led	to	increasing	operating	revenues	and	net	income.	

Our	Manufacturing	segment	produced	earnings	growth	in	2021	of	55.6%,	as	strong	end	market	demand	across	most	of	the	markets	we	serve	led	to	
increased	sales	volumes.	Higher	production	volumes	to	meet	customer	demand	led	to	improved	leveraging	of	fixed	manufacturing	costs	which,	
along	with	increased	prices,	led	to	improved	gross	profit	levels.	Our	Manufacturing	segment	was	impacted	in	2021	by	steel	supply	constraints	and	a	
significant	increase	in	steel	prices,	as	further	discussed	below.	

Our	Plastics	segment	produced	earnings	of	$97.8	million	in	2021,	compared	to	$27.6	million	in	2020.	The	unprecedented	level	of	earnings	in	2021	
resulted	from	extraordinary	industry	supply	and	demand	dynamics.	As	further	described	below,	supply	shortages	of	resin,	the	primary	raw	material	
used	in	the	manufacturing	of	PVC	pipe,	coupled	with	robust	end	market	demand	for	PVC	pipe	led	to	a	rapid	escalation	in	PVC	pipe	prices	and	gross	
margins.	Our	ability	to	manage	through	these	supply	disruptions	and	to	deliver	products	to	our	customers	allowed	us	to	capitalize	on	these	unique	
industry	conditions.

Collectively	in	2021,	our	businesses	generated	net	income	of	$176.8	million,	or	$4.23	per	diluted	share,	an	increase	of	84.4%	from	$95.9	million,	or	
$2.34	per	diluted	share,	in	2020.	In	2021,	we	paid	an	annual	dividend	of	$1.56	per	share,	or	$64.9	million,	completing	our	83rd	consecutive	year	of	
dividend	payments	to	our	shareholders.	

Our	earnings	mix	in	2021	was	41%	from	our	Electric	segment	and	59%	from	the	combination	of	our	Manufacturing	and	Plastics	segments	net	of	
unallocated	corporate	costs.	Electric	segment	earnings	as	a	percentage	of	our	total	earnings	were	less	than	our	long-term	estimate	of	70%	due	to	
the	unique	market	conditions	that	occurred	in	our	Plastics	segment.	We	expect	our	earnings	mix	to	return	back	to	our	expected	70%	from	our	
Electric	segment	and	30%	from	our	Manufacturing	and	Plastics	segments	over	the	long	term	as	the	conditions	within	the	Plastics'	industry	subside.		

RESOURCE	MATERIAL	AVAILABILITY	AND	PRICING	
Supply	shortages	and	the	cost	of	steel	and	resin,	two	key	material	inputs	to	our	Manufacturing	and	Plastics	segments,	respectively,	significantly	
impacted	our	operating	results	in	2021.	

Steel	supply	shortages	arose	in	2021	following	steel	mill	capacity	reductions	in	2020	in	response	to	lower	demand	due	to	COVID-19.	Production	and	
availability	of	steel	began	to	improve	late	in	2021	after	steel	mill	facilities	increased	production	capacities	in	response	to	strong	market	demand	for	
steel	products.	The	combination	of	supply	shortages	and	strong	end	user	demand	led	to	significantly	increased	steel	prices.	The	increase	in	steel	
prices	led	to	increased	sale	prices	for	our	products	at	BTD,	our	metal	fabrication	business	within	our	Manufacturing	segment,	as	we	passed	along	
material	cost	increases	to	our	customers.	Limited	steel	availability	also	heightened	the	complexity	in	managing	our	business,	including	effective	
management	of	our	production	and	shipping	schedules.	Steel	costs	began	to	recede	late	in	2021,	but	we	anticipate	steel	prices	will	remain	elevated	
relative	to	historic	norms	through	at	least	the	first	half	of	2022.	

PVC	resin	is	the	primary	material	input	of	the	PVC	pipe	manufactured	by	our	Plastics	segment	businesses.	Resin	supply	disruptions	initially	arose	as	
a	result	of	production	plant	shutdowns	due	to	abnormally	low	temperatures	and	ice	storms	in	the	Gulf	Coast	region	of	the	United	States	in	the	first	
quarter	of	2021	and	were	exacerbated	by	hurricane	activity	in	the	third	quarter	of	the	year.	These	supply	disruptions,	along	with	robust	domestic	
and	global	demand	for	PVC	resin	led	to	significantly	increased	resin	prices.

Limited	PVC	resin	resulted	in	reduced	manufacturing	of	PVC	pipe	and	low	pipe	inventories	across	the	industry.	The	combination	of	constrained	PVC	
resin	supply	and	the	resulting	low	PVC	pipe	inventories	along	with	significantly	increased	PVC	resin	costs	and	robust	demand	for	PVC	pipe	led	to	
rapidly	increasing	sale	prices	for	PVC	pipe,	with	the	increase	in	sale	prices	outpacing	the	increase	in	PVC	resin	costs,	leading	to	expanding	gross	
profit	margins	and	a	significant	increase	in	earnings	in	our	Plastics	segment.	We	anticipate	these	market	dynamics	will	continue	through	the	first	
quarter	of	2022	but	begin	to	subside	thereafter.	

The	marketplace	dynamics	impacting	both	our	Manufacturing	and	Plastics	segments	are	fluid	and	subject	to	change	which	may	impact	our	
operating	results	prospectively.

COVID-19
We	continue	to	monitor	the	progression	of	COVID-19	and	its	impact	on	our	business.	As	this	pandemic	continues,	we	are	following	the	directives	
and	advice	of	government	leaders	and	medical	professionals	and	have	adopted	practices	to	help	curtail	the	spread	of	the	virus	and	mitigate	its	
impact	on	our	employees,	customers,	vendors	and	other	business	partners,	and	communities	in	which	we	live	and	work.	

While	the	impact	of	COVID-19	and	the	resulting	macroeconomic	conditions	did	not	materially	impact	our	operating	results	in	2021,	uncertainty	
remains	regarding	the	magnitude	and	duration	of	the	pandemic	and	the	resulting	potential	future	financial	effects.	Increased	infection	rates	and	
any	future	responses	to	mitigate	the	spread	of	the	virus,	including	any	potential	vaccination	mandates	that	would	apply	to	our	employees,	could	
impact	our	business	and	our	financial	results	in	future	periods.	

OSHA	has	issued	an	ETS	requiring	all	employers	with	at	least	100	employees	to	ensure	their	employees	are	fully	vaccinated	or	require	weekly	
testing	for	unvaccinated	employees,	and	President	Biden	has	issued	an	executive	order,	which	requires	employees	of	certain	federal	contractors	

24

and	covered	subcontractors	to	be	vaccinated,	with	no	weekly	testing	option,	unless	they	have	an	approved	disability	or	religious	exemption.	OSHA	
has	withdrawn	its	ETS,	however,	they	have	emphasized	that	the	ETS	will	continue	to	serve	as	its	proposal	for	a	permanent	standard.	Currently,	the	
mandate	set	forth	by	the	President's	executive	order	has	been	halted	as	several	states	are	challenging	its	legality	and	the	matter	remains	in	
litigation.	If	these	mandates	are	upheld	in	federal	court	and	become	effective,	we	expect	one,	or	both,	of	these	new	regulations	will	apply	to	at	
least	some,	and	possibly	all,	of	our	businesses	which	could	require	us	to	mandate	COVID-19	vaccination	of	our	workforce	or	have	our	unvaccinated	
employees	undergo	required	weekly	COVID-19	testing,	or	some	combination	thereof,	which	could	be	difficult	and	costly.	Further,	additional	vaccine	
and	testing	mandates	may	be	announced	in	jurisdictions	in	which	we	operate	our	business,	and	there	could	be	potential	actions	by	certain	states	
that	are	in	conflict	with	the	federal	mandates,	the	impacts	of	which	remain	uncertain.	Requirements	to	mandate	COVID-19	vaccination	of	our	
workforce	or	requirements	of	our	unvaccinated	employees	to	be	tested	could	result	in	labor	disruptions,	employee	attrition	and	difficulty	securing	
future	labor	needs.

We	continue	to	monitor	developments	involving	our	workforce,	customers,	construction	contractors,	suppliers	and	vendors	and	the	financial	
effects	on	our	business.	However,	due	to	the	unprecedented	and	evolving	nature	of	this	pandemic,	we	cannot	predict	the	full	extent	of	the	impact	
COVID-19	will	have	on	our	operating	results,	financial	condition	and	liquidity.

FINANCIAL	AND	OTHER	METRICS

Heating	Degree	Days	(HDDs)	is	a	measure	of	how	much	(in	degrees),	and	for	how	long	(in	days),	the	outside	air	temperature	was	below	a	certain	
normalized	level.	This	measure	is	commonly	used	in	calculations	relating	to	the	energy	consumption	required	to	heat	buildings.

Cooling	Degree	Days	(CDDs)	is	a	measure	of	how	much	(in	degrees),	and	for	how	long	(in	days),	the	outside	air	temperature	was	above	a	certain	
normalized	level.	This	measure	is	commonly	used	in	calculations	relating	to	the	energy	consumption	required	to	cool	buildings.

Otter	Tail	Power	Company	(OTP)	generally	bases	its	forecasted	kilowatt-hour	(kwh)	sales	and	rates	on	expected	consumption	under	a	normal	level	
of	HDDs	and	CDDs	over	a	given	period	of	time	in	its	service	territory.	Increased	or	decreased	levels	of	consumption	for	certain	customer	
classifications	are	attributed	to	deviation	from	the	norms	and	are	a	significant	factor	influencing	consumption	of	electricity	across	our	service	
territory.	We	present	HDDs	and	CDDs	to	provide	an	indication	of	the	impact	of	weather	on	kwh	sales,	revenues	and	earnings	relative	to	forecast	
and	on	period-to-period	results.

Utility	Rate	Base	is	the	value	of	property	on	which	a	public	utility	is	permitted	to	earn	a	specified	rate	of	return	in	accordance	with	rules	set	by	a	
regulatory	agency.	In	general,	rate	base	consists	of	the	value	of	property	used	by	the	utility	in	providing	service.	Rate	base	can	also	include:	cash,	
working	capital,	materials	and	supplies,	deductions	for	accumulated	provisions	for	depreciation,	contributions	in	aid	of	construction,	customer	
advances	for	construction,	accumulated	deferred	income	taxes,	and	accumulated	deferred	investment	tax	credits,	dependent	on	the	method	that	is	
used	in	the	calculation,	which	can	vary	from	jurisdiction	to	jurisdiction.	We	present	actual	and	forecasted	levels	of	utility	rate	base	to	provide	an	
indication	of	expected	investments	on	which	we	expect	to	earn	future	returns.

Provided	below	is	a	summary	and	discussion	of	our	operating	results	on	a	consolidated	basis	followed	by	a	discussion	of	the	operating	results	of	
each	of	our	segments,	Electric,	Manufacturing	and	Plastics.	Intersegment	transactions	were	not	material	in	2021	or	2020	and	amounted	to	less	than	
$0.1	million	of	operating	revenues	and	operating	expenses	for	each	year.	In	addition	to	the	segment	results,	we	provide	an	overview	of	our	
Corporate	costs.	Our	Corporate	costs	do	not	constitute	a	reportable	segment	but	rather	consist	of	unallocated	general	corporate	expenses,	such	as	
corporate	staff	and	overhead	costs,	the	results	of	our	captive	insurance	company	and	other	items	excluded	from	the	measurement	of	segment	
performance.	Corporate	costs	are	added	to	operating	segment	totals	to	reconcile	to	totals	on	our	consolidated	statements	of	income.

Operating	Revenues	increased	$306.7	million	on	a	consolidated	basis	in	2021.	Each	operating	segment	contributed	to	the	growth	in	operating	
revenues.	Electric	segment	operating	revenue	increased	7.7%	primarily	due	to	increased	retail,	transmission	and	wholesale	revenues.	
Manufacturing	segment	operating	revenues	increased	40.8%	mainly	as	a	result	of	higher	material	input	costs,	primarily	steel,	which	are	passed

through	to	customers,	and	increased	volumes	due	to	strong	end	market	demand.	Plastics	segment	operating	revenues	increased	85.3%	primarily	
due	to	unique	supply	and	demand	dynamics	resulting	from	resin	supply	constraints	coupled	with	robust	demand	for	PVC	pipe	leading	to	rapid	and	
significant	increases	in	sale	prices	of	PVC	pipe.	See	our	segment	disclosures	below	for	additional	discussion	of	items	impacting	operating	revenues.

Operating	Expenses	increased	$204.9	million	in	2021.	Electric	segment	operating	expenses	increased	10.1%	primarily	due	to	increased	production	
fuel	and	purchased	power	costs	along	with	incremental	operating	costs	and	depreciation	expense	rising	from	our	recent	rate	base	investments.	
Operating	expenses	in	our	Manufacturing	segment	increased	40.2%,	driven	by	increased	cost	of	products	sold,	which	resulted	from	higher	material	
input	costs	and	increased	sales	volumes,	and	increased	other	operating	expenses.	Operating	expenses	in	our	Plastics	segment	increased	47.8%	
primarily	due	to	higher	costs	of	products	sold	from	higher	resin	inputs	costs.	See	our	segment	disclosures	below	for	additional	discussion	of	items	
impacting	operating	expenses.

Interest	Charges	increased	$3.3	million	in	2021	due	to	a	$40.0	million	long-term	debt	issuance	in	August	2020,	a	higher	level	of	short-term	debt	
borrowings	outstanding	in	2021	and	a	lower	level	of	capitalized	interest	due	to	the	completion	and	placement	in	service	of	Astoria	Station	in	the	
first	quarter	of	2021.	The	increase	in	our	short-	and	long-term	debt	borrowings	were	largely	used	to	finance	the	rate	base	investments	in	our	
Electric	segment.

Nonservice	Cost	Components	of	Postretirement	Benefits	decreased	$1.4	million	in	2021	mostly	due	to	a	decrease	in	nonservice	costs	of	our	
postretirement	healthcare	plan	reflecting	the	effect	of	plan	amendments	adopted	in	2020	and	2019.

Other	Income	decreased	$3.2	million	in	2021	due	to	a	reduction	of	allowance	for	equity	funds	used	during	construction	(AFUDC)	on	Electric	
segment	investments,	mainly	for	the	Minnesota	share	of	Astoria	Station.	Astoria	Station	was	placed	into	service,	and	the	recognition	of	AFUDC	
discontinued,	in	the	first	quarter	of	2021.

Income	Tax	Expense	increased	$15.8	million	in	2021	primarily	due	to	an	increase	in	income	before	income	taxes,	but	partially	offset	by	an	increase	
in	production	tax	credits	generated	from	our	Merricourt	wind	farm,	which	was	placed	in	service	in	the	fourth	quarter	of	2020.	Our	effective	tax	rate	
was	16.9%	in	2021	and	17.4%	in	2020.	See	Note	12	to	our	consolidated	financial	statements	included	in	the	report	on	Form	10-K	for	additional	
information	regarding	factors	impacting	our	effective	tax	rate.

Retail	Revenues	increased	$16.0	million	primarily	due	to	the	following:

•

•

•

An	$8.1	million	increase	in	fuel	recovery	revenues	primarily	resulting	from	increased	production	fuel	and	purchase	power	costs,	both	of	
which	were	impacted	by	increasing	natural	gas	prices	throughout	most	of	2021.	Partially	offsetting	this	increase	are	credits	provided	to	
retail	customers	from	increased	margins	recognized	on	wholesale	sales.

A	$6.6	million	increase	in	rider	revenues	in	our	North	Dakota	and	South	Dakota	jurisdictions	primarily	to	recover	our	investments	in	and	
costs	to	operate	Merricourt	and	Astoria	Station.

A	$5.0	million	increase	in	new	retail	revenues	from	an	interim	rate	increase	in	Minnesota,	net	of	estimated	refunds.

These	increases	in	retail	revenue	were	partially	offset	by	the	impact	of	reduced	demand,	exclusive	of	the	impact	of	weather,	from	
residential	customers,	and	net	of	the	effect	of	a	change	in	customer	usage	mix.	In	addition,	retail	revenue	in	2020	benefited	from	the	
recognition	of	$2.6	million	of	Minnesota	transmission	rider	revenue	resulting	from	a	favorable	judicial	decision	regarding	the	state	
jurisdictional	treatment	of	federally	approved	transmission	projects.	

Transmission	Services	Revenues	increased	$4.8	million	primarily	due	to	increased	recovery	of	higher	transmission	costs	and	increased	transmission	
investment	along	with	increased	generator	interconnection	revenues.

Wholesale	Revenues	increased	$13.1	million	as	a	result	of	a	77.6%	increase	in	wholesale	sales	volumes	and	a	107.9%	increase	in	wholesale	prices	
driven	by	increased	fuel	costs	and	market	demand	for	wholesale	energy,	which	serves	to	drive	up	spot	market	prices	for	electricity.	

Production	Fuel	costs	increased	$13.0	million	as	a	result	of	a	16.9%	increase	in	kwhs	generated	from	our	fuel-burning	plants,	largely	driven	by	
output	from	Astoria	Station	after	energy	generation	commenced	in	April	of	2021.

Purchased	Power	costs	increased	$3.7	million	due	to	a	27.9%	increase	in	the	cost	per	kwh	purchased	in	2021.	This	increase	was	partially	offset	by	a	
17.1%	decrease	in	the	volume	of	purchased	power	in	2021	as	our	recent	generation	additions	provide	additional	generation	resources	to	serve	
customer	demand	and	market	conditions	led	to	operating	our	facilities	at	higher	capacity	factors	in	lieu	of	purchasing	power	at	higher	market	
prices.

Operating	and	Maintenance	Expense	increased	$8.8	million	mainly	due	to:

•

•

•

A	$5.2	million	increase	in	operating	and	maintenance	costs	for	Merricourt	and	Astoria	Station	as	these	facilities	were	placed	in	service	in	
the	fourth	quarter	of	2020	and	the	first	quarter	of	2021,	respectively.

A	$4.0	million	increase	in	Big	Stone	plant	maintenance	costs	arising	from	our	planned	facility	outage,	which	began	in	the	third	quarter	and	
was	completed	in	the	fourth	quarter	of	2021.

Other	additional	costs	including	a	$2.2	million	increase	in	transmission	tariff	expenses	and	increases	in	information	technology	services,	
insurance	costs	and	increased	vegetative	maintenance	costs.

These	expense	increases	were	partially	offset	by,	among	other	items,	a	$3.0	million	reduction	in	bad	debt	expense	as	customer	
collections	have	improved	from	2020,	which	were	negatively	impacted	by	the	economic	effects	of	COVID-19,	along	with	lower	operating	
costs	following	the	closure	of	Hoot	Lake	Plant	in	May	2021.

Depreciation	and	Amortization	expense	increased	$8.2	million	primarily	due	to	Merricourt	and	Astoria	Station	being	placed	in	service	in	the	fourth	
quarter	of	2020	and	the	first	quarter	of	2021,	respectively.

Operating	Revenues	increased	$97.5	million	primarily	due	to	the	following:

•

At	BTD,	operating	revenues	increased	$91.3	million.	Parts	revenue	increased	$78.4	million,	primarily	due	to	a	31.2%	increase	in	material	
costs,	which	are	passed	through	to	customers,	as	steel	prices	increased	significantly	from	the	previous	year.	Steel	prices	increased	during	
the	year	as	steel	mill	production	did	not	match	customer	demand	as	mill	capacity	recovered	from	shutdowns	in	2020	resulting	from	the	
COVID-19	pandemic.	Sales	volumes	increased	6.8%	in	2021	from	increased	and	robust	end	market	demand	across	most	markets	served.	
Demand	in	2020	was	impacted	by	COVID-19	after	certain	customers	implemented	temporary	plant	shutdowns	in	response	to	the	
pandemic.	A	$7.3	million	increase	in	scrap	revenues,	with	$5.9	million	due	to	higher	scrap	metal	prices	and	$1.4	million	attributable	to	
higher	volumes,	also	contributed	to	the	increase	in	operating	revenues.

27

	
	
	
	
	
	
	
	
	
	
•

At	T.O.	Plastics,	revenues	increased	$6.2	million,	primarily	due	to	a	12.5%	increase	in	sales	volumes	as	well	as	5.6%	increase	in	sale	prices.	
Increases	in	horticultural	product	sales	volumes	due	to	strong	customer	demand	during	the	year	were	partially	offset	by	decreases	in	
sales	to	other	end	market	customers.	Sales	volumes	in	2020	were	impacted	by	the	COVID-19	pandemic,	as	certain	end	markets	
experienced	reduced	demand.

Cost	of	Products	Sold	increased	$79.1	million	due	to	the	following:

•

•

Cost	of	products	sold	at	BTD	increased	$76.6	million	as	a	result	of	both	increased	material	costs	and	higher	sales	volumes.	Increased	gross	
profit	margins	resulting	from	a	higher	leveraging	of	fixed	costs	due	to	increased	sales	volumes	were	partially	offset	by	lower	productivity	
and	increased	labor	and	freight	costs.	The	lower	level	of	productivity	during	the	year	was	primarily	the	result	of	increased	staffing	levels	
to	meet	higher	business	volumes	and	the	time	required	for	new	employees	to	achieve	peak	productivity.

Cost	of	products	sold	at	T.O.	Plastics	increased	$3.2	million	primarily	due	to	increased	sales	volumes.	Gross	profit	margins	increased	as	a	
result	of	a	higher	leveraging	of	fixed	costs	due	to	increased	sales	volumes	and	better	pricing	spreads.

Other	Operating	Expenses	increased	$9.9	million	due	to	increased	staffing	levels	and	associated	recruitment	costs,	travel	costs,	incentive	based	
compensation	and	other	costs	resulting	from	higher	business	volumes.

Operating	Revenues	increased	$175.0	million	primarily	due	to	unique	supply	and	demand	dynamics	during	the	year.	The	average	price	per	pound	
of	PVC	pipe	sold	in	2021	increased	82.1%	compared	to	2020,	which	exceeded	the	65.5%	increase	in	the	cost	of	PVC	resin	and	other	input	materials.	
The	increase	in	sale	prices	was	largely	due	to	the	combination	of	PVC	resin	supply	constraints,	which	limited	PVC	pipe	manufacturing	output	and	led	
to	extremely	low	inventory	levels,	and	strong	demand	for	PVC	pipe	products.	Resin	supply	was	negatively	impacted	during	the	year	by	production	
disruptions	caused	by	extreme	weather	events	in	the	Gulf	Coast	region	of	the	U.S.	in	the	first	and	third	quarters	of	the	year.	Pounds	of	pipe	sold	in	
2021	increased	1.7%	compared	to	the	previous	year.

Cost	of	Products	Sold	increased	$80.0	million	primarily	due	to	the	increase	in	the	cost	per	pound	of	PVC	pipe	sold	largely	due	to	higher	material	
input	costs.		

Other	Operating	Expenses	decreased	$0.7	million.	In	2020,	our	Plastics	businesses	made	a	$2.0	million	contribution	commitment	to	OTC’s	
charitable	foundation,	and	no	such	contribution	commitment	was	made	in	2021.	The	decrease	in	foundation	contributions	was	partially	offset	by	
an	increase	in	variable	costs	associated	with	the	increased	financial	results	in	2021.

(1)	Includes	an	earnings	sharing	mechanism	to	share	with	South	Dakota	customers	any	weather-normalized	earnings	above	the	authorized	ROE	of	8.75%.	The	
mechanism	requires	annual	customer	refunds	of	50%	of	any	weather-normalized	revenue	creating	earnings	in	excess	of	the	authorized	ROE	up	to	a	maximum	of	9.50%	
and	100%	refunds	revenue	creating	earnings	above	9.50%.

Minnesota	Rate	Case:	On	November	2,	2020,	OTP	filed	a	request	with	the	MPUC	for	an	increase	in	revenue	recoverable	through	base	rates	in	
Minnesota.	In	its	filing,	OTP	requested	a	net	increase	in	annual	revenue	of	approximately	$14.5	million,	or	6.77%,	based	on	an	allowed	rate	of	
return	on	rate	base	of	7.59%	and	an	allowed	rate	of	return	on	equity	of	10.20%	on	an	equity	ratio	of	52.5%	of	total	capital.	Through	this	
proceeding,	OTP	has	proposed	changes	to	the	mechanism	of	cost	recovery,	with	some	costs	moving	from	riders	into	base	rates	and	fuel,	purchased	
power,	and	conservation	program	costs	moving	out	of	base	rates	and	into	riders.	The	filing	also	included	a	revenue	decoupling	mechanism	
proposal.	Such	mechanisms	are	designed	to	separate	a	utility's	revenue	from	changes	in	energy	sales.	The	decoupling	mechanism	uses	a	tracker	
balance	through	which	authorized	customer	margins	are	subject	to	a	true-up	mechanism	to	maintain	or	cap	a	given	level	of	revenues.	

On	December	3,	2020,	the	MPUC	approved	an	interim	annual	rate	increase	of	$6.9	million,	or	3.2%,	effective	January	1,	2021.	This	approval	was	
provided	after	an	alternative	recovery	proposal	was	submitted	by	OTP,	which,	among	other	changes,	requested	the	extension	of	depreciable	lives	
of	certain	wind-related	assets	and	deferred	certain	cost	recovery	decisions	to	the	final	rate	determination.	In	the	aggregate,	this	alternative	
recovery	proposal	reduced	operating	costs	and	delayed	recovery	of	certain	other	costs	by	approximately	$7.0	million	to	lessen	the	interim	rate	
impact	on	customers.

In	a	filing	submitted	to	the	MPUC	on	April	30,	2021,	OTP	lowered	its	requested	net	annual	revenue	increase	from	its	initial	request	of	$14.5	million	
to	$8.2	million,	primarily	due	to	a	reduction	in	operating	costs	from	amounts	included	in	its	November	2020	filing.	The	cost	reductions	include,	
among	other	items,	lower	depreciation	expense	on	our	wind	generation	assets	due	to	the	extension	of	depreciable	lives	from	25	to	35	years	and	a	
reduction	in	postretirement	benefit	costs.

On	February	1,	2022,	the	MPUC	issued	its	written	order.	The	key	provisions	of	the	order	include	a	revenue	requirement	of	$209.0	million	based	on	
a	return	on	rate	base	of	7.18%,	including	an	allowed	return	on	equity	of	9.48%	on	an	equity	ratio	of	52.5%.	The	order	also	authorizes	recovery,	over	
a	five-year	period,	of	our	remaining	Hoot	Lake	Plant	net	asset	and	approves	the	requested	decoupling	mechanism	for	most	residential	and	
commercial	customer	rate	groups,	with	a	cap	of	4%	of	annual	base	revenues.	Following	the	submission	of	certain	compliance	filings	and	a	comment	
period	on	such	filings,	we	expect	final	rates	will	be	implemented	in	mid-2022.

Minnesota	TCR:	On	May	1,	2017,	the	MPUC	ordered	OTP	to	include	in	the	TCR	rider	retail	rate	base	the	Minnesota	jurisdictional	share	of	OTP's	
investments	in	certain	transmission	assets	and	all	revenues	received	from	other	utilities	under	MISO's	tariffed	rates	as	a	credit	in	its	TCR	revenue	
requirement	calculations.	The	order	had	the	effect	of	diverting	interstate	wholesale	revenues	that	have	been	approved	by	the	FERC	to	offset	the	
FERC-approved	expenses,	effectively	reducing	OTP's	recovery	of	FERC-approved	expense	levels.	

On	August	18,	2017,	OTP	filed	an	appeal	of	the	MPUC	order	with	the	Minnesota	Court	of	Appeals	to	contest	the	portion	of	the	order	requiring	OTP	
to	jurisdictionally	allocate	costs	of	the	FERC	transmission	projects	in	the	TCR	rider.	On	June	11,	2018,	the	Minnesota	Court	of	Appeals	reversed	the	
MPUC's	order.	On	July	11,	2018,	the	MPUC	filed	a	petition	for	review	of	the	decision	to	the	Minnesota	Supreme	Court,	which	granted	review	of	the	
appellate	court	decision.	The	Minnesota	Supreme	Court	issued	its	opinion	on	April	22,	2020,	concluding	the	MPUC	lacked	authority	to	amend	an	
existing	TCR	rider	approved	under	Minnesota	state	law	to	include	the	costs	and	revenues	associated	with	these	transmission	projects	and	affirming	
the	decision	of	the	Minnesota	Court	of	Appeals.

On	October	22,	2020,	the	MPUC	approved	OTP's	request	for	a	Minnesota	TCR	rider	update	with	the	exclusion	of	these	transmission	projects.	In	
addition,	the	MPUC	approved	the	inclusion	of	three	new	projects	previously	requested	in	the	Minnesota	TCR	rider	eligibility	petition.	Updated	rates	
went	into	effect	in	January	2021.	With	this	decision,	one-half	of	the	projected	TCR	rider	tracker	balance	at	December	2020	of	$13.4	million	will	be	
included	in	the	2021	TCR	rider	annual	revenue	requirement,	with	the	remainder	included	in	the	next	annual	update.	The	annual	updates	provide	
for	recovery	of	approximately	$2.6	million	in	MISO	revenue	credits	to	Minnesota	customers	through	the	TCR	rider	prior	to	September	30,	2020.	As	
a	result,	OTP	recognized	additional	rider	revenue	of	$2.6	million	during	the	third	quarter	of	2020.

LIQUIDITY

LIQUIDITY	OVERVIEW
We	believe	our	financial	condition	is	strong	and	our	cash,	other	liquid	assets,	operating	cash	flows,	existing	lines	of	credit,	access	to	capital	markets,	
and	borrowing	ability	because	of	investment-grade	credit	ratings,	when	taken	together,	provide	us	ample	liquidity	to	conduct	business	operations	
and	fund	capital	expenditures	related	to	expansion	of	existing	businesses	and	development	of	new	projects.	Our	liquidity,	including	our	operating	
cash	flows	and	access	to	capital	markets,	can	be	impacted	by	macroeconomic	factors	outside	of	our	control,	such	as	those	which	may	be	caused	by	
COVID-19.	In	addition,	our	liquidity	could	be	impacted	by	non-compliance	with	covenants	under	our	various	debt	instruments.	As	of	December	31,	
2021,	we	were	in	compliance	with	all	debt	covenants	(see	the	Financial	Covenant	section	under	Capital	Resources	below).

The	following	table	presents	the	status	of	our	lines	of	credit	as	of	December	31,	2021	and	2020:

We	have	an	internal	risk	tolerance	metric	to	maintain	a	minimum	of	$50	million	of	liquidity	under	the	OTC	Credit	Agreement.	Should	additional	
liquidity	be	needed,	this	agreement	includes	an	accordion	feature	allowing	us	to	increase	the	amount	available	to	$290	million,	subject	to	certain	
terms	and	conditions.	The	OTP	Credit	Agreement	also	includes	an	accordion	feature	allowing	OTP	to	increase	that	facility	to	$250	million,	subject	to	
certain	terms	and	conditions.

CASH	FLOWS
The	following	is	a	discussion	of	our	cash	flows	for	the	years	ended	December	31,	2021	and	2020:

2020

$	

231,243	

$	

211,921	

Net	Cash	Provided	by	Operating	Activities	increased	$19.3	million	primarily	due	to	a	$80.9	million	increase	in	net	income,	but	partially	offset	by	an	
increase	in	working	capital.	Our	working	capital	increase	was	primarily	the	result	of	a	$61.0	million	increase	in	accounts	receivable	and	a	$54.3	
million	increase	in	inventories,	which	exceeded	the	increase	in	accounts	payable	and	accrued	and	other	liabilities.	The	increase	in	accounts	
receivable	was	primarily	due	to	increased	sales	prices	in	our	Manufacturing	and	Plastics	segments,	as	well	as	increased	sales	volumes	in	our	Plastics	
segment	in	the	fourth	quarter	of	2021	compared	to	the	fourth	quarter	of	2020.	The	increase	in	inventories	was	largely	the	result	of	increased	
material	costs	within	our	Manufacturing	and	Plastics	segments.	The	increase	in	material	costs	of	our	Plastics	segment	more	than	offset	the	
significant	decrease	in	pounds	of	pipe	inventory,	which	decreased	as	a	result	of	lower	manufacturing	output	due	to	resin	supply	constraints	and	
strong	demand	for	PVC	pipe.	The	increase	in	accounts	payable	was	largely	due	to	the	increased	material	costs	in	our	Manufacturing	and	Plastics	
segments	and	increased	inventory	levels	primarily	in	our	Manufacturing	segment.

Net	Cash	(Used	in)	Provided	by	Financing	Activities	decreased	$203.1	million	primarily	related	to	a	decrease	in	construction	financing	needs	within	
our	Electric	segment,	as	capital	spending	was	substantially	complete	for	both	Astoria	Station	and	Merricourt	by	year-end	2020.	In	2021	our	
financing	activities	included	the	issuance	of	$140.0	million	in	long-term	debt	at	OTP,	which	was	used	to	repay	long-term	debt	that	matured	in	
December	2021,	and	$10.2	million	of	net	short-term	borrowings	on	our	lines	of	credit,	which	were	primarily	used	to	fund	construction	expenditures	
and	support	operating	activities.	In	2021,	we	paid	$64.9	million	in	dividends	to	common	shareholders.	In	2020,	$75.0	million	of	long-term	debt	was	
issued	at	OTP,	we	had	$75.0	million	of	net	short-term	borrowings	on	our	lines	of	credit,	and	we	also	raised	$52.4	million	from	the	issuance	of	
common	stock	to	fund	capital	expenditures	at	OTP.	In	2020,	we	paid	$60.3	million	in	dividends	to	common	shareholders.

CAPITAL	REQUIREMENTS

CAPITAL	EXPENDITURES
We	have	a	capital	expenditure	program	for	expanding,	upgrading	and	improving	our	facilities	and	operating	equipment.	Typical	uses	of	cash	for	
capital	expenditures	are	investments	in	electric	generation	facilities	and	environmental	upgrades,	transmission	and	distribution	lines,	
manufacturing	facilities	and	upgrades,	equipment	used	in	the	manufacturing	process,	and	computer	hardware	and	information	systems.	The	capital	
expenditure	program	is	subject	to	review	and	is	revised	in	light	of	changes	in	demands	for	energy,	technology,	environmental	laws,	regulatory	
changes,	business	expansion	opportunities,	the	costs	of	labor,	materials	and	equipment	and	our	financial	condition.

The	following	provides	a	summary	of	capital	expenditures	for	the	years	ended	December	31,	2021	and	2020	for	our	Electric	segment	and	non-

Coal	contract	obligations	are	based	on	estimated	coal	consumption	and	costs	for	the	delivery	of	coal	to	Coyote	Station	from	Coyote	Creek	Mining	
Company	under	the	lignite	sales	agreement	that	ends	in	2040.	Postretirement	benefit	obligations	include	estimated	cash	expenditures	for	the	
payment	of	retiree	medical	and	life	insurance	benefits	and	supplemental	pension	benefits	under	our	unfunded	Executive	Survivor	and	
Supplemental	Retirement	Plan,	but	do	not	include	amounts	to	fund	our	noncontributory	funded	pension	plan,	as	we	are	not	currently	required	to	
make	a	contribution	to	that	plan.

Off-Balance	Sheet	Arrangements
As	of	December	31,	2021,	we	have	outstanding	letters	of	credit	totaling	$15.9	million,	a	portion	of	which	reduces	our	borrowing	capacity	under	our	
lines	of	credit.	No	outstanding	letters	of	credit	are	reflected	in	outstanding	short-term	debt	on	our	consolidated	balance	sheets.	

We	do	not	have	any	other	off-balance-sheet	arrangements	or	any	relationships	with	unconsolidated	entities	or	financial	partnerships.	These	
entities	are	often	referred	to	as	structured	finance	special	purpose	entities	or	variable	interest	entities,	which	are	established	for	the	purpose	of	
facilitating	off-balance-sheet	arrangements	or	for	other	contractually	narrow	or	limited	purposes.	We	are	not	exposed	to	any	financing,	liquidity,	
market	or	credit	risk	that	could	arise	if	we	had	such	relationships.

COMMON	STOCK	DIVIDENDS
We	paid	dividends	to	our	shareholders	totaling	$64.9	million,	or	$1.56	per	share,	in	2021.	The	determination	of	the	amount	of	future	cash	
dividends	to	be	paid	will	depend	on,	among	other	things,	our	financial	condition,	improvement	in	earnings	per	share,	cash	flows	from	operations,	
the	level	of	our	capital	expenditures	and	our	future	business	prospects.	As	a	result	of	certain	statutory	limitations	or	regulatory	or	financing	
agreements,	restrictions	could	occur	on	the	amount	of	distributions	allowed	to	be	made	by	our	subsidiaries.	See	Note	14	to	our	consolidated

Board	of	Directors.	On	February	4,	2022,	our	Board	of	Directors	increased	the	quarterly	dividend	from	$0.39	to	$0.4125	per	common	share.

CAPITAL	RESOURCES

Financial	flexibility	is	provided	by	operating	cash	flows,	unused	lines	of	credit,	strong	financial	coverages,	investment	grade	credit	ratings	and	
alternative	financing	arrangements	such	as	leasing.	Debt	financing	will	be	required	in	the	five-year	period	from	2022	through	2025	to	refinance	
maturing	debt	and	to	finance	our	capital	investments	within	our	Electric	segment.	Our	financing	plans	are	subject	to	change	and	are	impacted	by	
our	planned	level	of	capital	investments,	a	decision	to	reduce	borrowings	under	our	lines	of	credit,	to	refund	or	retire	early	any	of	our	presently	
outstanding	debt,	to	complete	acquisitions	or	for	other	corporate	purposes.	

REGISTRATION	STATEMENTS
On	May	3,	2021,	we	filed	a	shelf	registration	statement	with	the	SEC	under	which	we	may	offer	for	sale,	from	time	to	time,	either	separately	or	
together	in	any	combination,	equity,	debt	or	other	securities	described	in	the	shelf	registration	statement.	The	registration	statement	expires	in	
May,	2024.	No	shares	were	issued	pursuant	to	the	registration	statement	in	2021.

On	May	3,	2021,	we	filed	a	second	registration	statement	with	the	SEC	for	the	issuance	of	up	to	1,500,000	common	shares	under	an	Automatic	
Dividend	Reinvestment	and	Share	Purchase	Plan,	which	provides	shareholders,	retail	customers	of	OTP	and	other	interested	investors	a	method	of	
purchasing	our	common	shares	by	reinvesting	their	dividends	and/or	making	optional	cash	investments.	Shares	purchased	under	the	plan	may	be	
new	issue	common	shares	or	common	shares	purchased	on	the	open	market.	The	registration	statement	expires	in	May	2024.	In	2021,	we	issued	
115,180	shares	under	the	plan.	All	shares	issued	under	the	plan	to	date	have	been	open	market	purchases	and	there	have	been	no	new	issue	
shares,	resulting	in	no	proceeds	received	by	the	Company.		As	of	December	31,	2021,	1,384,820	shares	remain	available	for	purchase	or	issuance	
under	the	Plan.

SHORT-TERM	DEBT
OTC	and	OTP	are	each	party	to	a	credit	agreement	(the	OTC	Credit	Agreement	and	OTP	Credit	Agreement,	respectively)	which	provides	for	
unsecured	revolving	lines	of	credit.	The	agreements	generally	bear	interest	at	the	London	Interbank	Offered	Rate	(LIBOR)	plus	an	applicable	credit	
spread,	which	is	subject	to	adjustment	based	on	the	credit	ratings	of	the	issuer.	The	weighted-average	interest	rate	on	all	outstanding	borrowings	
as	of	December	31,	2021	and	2020	was	1.42%	and	1.61%.

LONG-TERM	DEBT	
At	December	31,	2021,	we	had	$767.0	million	of	principal	outstanding	under	long-term	debt	arrangements.	Note	9	to	our	consolidated	financial	
statements	included	in	this	report	on	Form	10-K	includes	information	regarding	these	instruments.	The	agreements	generally	provide	for	unsecured	
borrowings	at	fixed	rates	of	interest	with	maturities	ranging	from	2022	to	2051.	One	OTP	debt	instrument	with	a	principal	balance	of	$30.0	million	
matures	in	August	2022.	Pursuant	to	a	Note	Purchase	Agreement	executed	in	June	2021,	OTP	intends	to	issue	its	Series	2022A	notes	in	May	2022,	
for	aggregate	proceeds	of	$90.0	million,	subject	to	the	satisfaction	of	certain	customary	conditions	to	closing,	and	use	a	portion	of	the	proceeds	to	
repay	the	$30.0	million	which	is	maturing	in	August	2022.

Financial	Covenants
Certain	of	our	short-	and	long-term	debt	agreements	require	OTC	and	OTP	to	maintain	certain	financial	covenants.	As	of	December	31,	2021,	we	
were	in	compliance	with	these	financial	covenants	as	further	described	below:	

OTC,	under	its	financial	covenants,	may	not	permit	its	ratio	of	Interest-Bearing	Debt	to	Total	Capitalization	to	exceed	0.60	to	1.00,	may	not	
permit	its	Interest	and	Dividend	Coverage	Ratio	to	be	less	than	1.50	to	1.00,	and	may	not	permit	its	Priority	Indebtedness	to	exceed	10%	of	our	
Total	Capitalization.	As	of	December	31,	2021,	our	Interest-Bearing	Debt	to	Total	Capitalization	was	0.46	to	1.00,	our	Interest	and	Dividend	
Coverage	Ratio	was	6.82	to	1.00	and	we	had	no	Priority	Indebtedness	outstanding.

OTP	under	its	financial	covenants,	may	not	permit	its	ratio	of	Debt	to	Total	Capitalization	to	exceed	0.60	to	1.00,	may	not	permit	its	Interest	and	
Dividend	Coverage	Ratio	to	be	less	than	1.50	to	1.00,	and	may	not	permit	its	Priority	Debt	to	exceed	20%	of	its	Total	Capitalization.	As	of

1.00	and	it	had	no	Priority	Indebtedness	outstanding.	

None	of	our	debt	agreements	include	any	provisions	that	would	trigger	an	acceleration	of	the	related	debt	as	a	result	of	changes	in	the	credit	rating	
levels	assigned	to	the	related	obligor	by	rating	agencies.

CRITICAL	ACCOUNTING	POLICIES	INVOLVING	SIGNIFICANT	ESTIMATES

Preparation	of	financial	statements	in	accordance	with	accounting	principles	generally	accepted	in	the	United	States	of	America	requires	
management	to	make	estimates	and	judgments	that	affect	the	reported	amounts	of	assets,	liabilities,	revenues	and	expenses,	and	related	
disclosure	of	contingent	assets	and	liabilities.	While	we	believe	the	estimates	and	judgments	we	use	in	preparing	our	consolidated	financial	
statements	are	appropriate	and	are	based	on	the	best	available	information,	they	are	subject	to	future	events	and	uncertainties	regarding	their	
outcome	and	therefore	actual	results	may	materially	differ	from	these	estimates.	Management	has	discussed	the	application	of	these	critical	
accounting	policies	and	the	development	of	these	estimates	with	the	Audit	Committee	of	our	Board	of	Directors.	The	following	critical	accounting	
policies	affect	the	most	significant	judgments	and	estimates	used	in	the	preparation	of	our	consolidated	financial	statements.

REGULATORY	ACCOUNTING
Our	utility	business	is	subject	to	regulation	of	rates	and	other	matters	by	state	utility	commissions	in	Minnesota,	North	Dakota	and	South	Dakota	
and	by	the	FERC	for	certain	interstate	operations.	Accordingly,	our	utility	business	must	adhere	to	the	accounting	requirements	of	regulated	
operations,	which	requires	the	recognition	of	regulatory	assets	and	regulatory	liabilities	for	amounts	that	otherwise	would	impact	the	statement	of	
income	or	comprehensive	income	when	it	is	probable	that	such	amounts	will	be	collected	from	customers	or	credited	to	customers	through	the	
rate-making	process.	This	guidance	also	provides	recognition	criteria	for	adjustments	to	rates	outside	of	a	general	rate	case	proceeding	which	are	
provided	to	encourage	or	incentivize	investments	in	certain	areas	such	as	conservation,	renewable	energy,	pollution	reduction	or	control,	improved	
infrastructure	of	the	transmission	grid	or	other	programs	that	provide	benefits	to	the	general	public	under	public	policy,	laws	or	regulations.	
Regulatory	assets	generally	represent	costs	that	have	been	incurred	but	have	been	deferred	because	future	recovery	from	customers,	as	
established	through	the	rate-making	process,	is	probable.	Regulatory	liabilities	generally	represent	amounts	to	be	refunded	to	customers	or	
amounts	currently	collected	from	customers	for	future	costs.	

We	assess	the	probability	of	recovery	of	regulatory	assets	and	the	obligations	arising	from	regulatory	liabilities	on	a	quarterly	basis.	Our	probability	
estimates	incorporate	numerous	factors,	including	recent	rate	making	decisions,	historical	precedents	for	similar	matters,	the	regulatory	
environments	in	which	we	operate	and	the	impact	these	incurred	costs	may	have	on	our	customers.	Changes	in	our	assessments	regarding	the	
likelihood	of	recovery	or	settlement	of	our	regulatory	assets	and	liabilities	may	have	a	material	impact	on	our	operating	results	and	financial	
position.	Further,	if	we	determine	that	all	or	a	portion	of	our	utility	business	no	longer	meets	the	criteria	for	continued	application	of	regulatory	
accounting,	or	our	regulators	disallow	recovery	of	a	previously	incurred	cost	or	eliminate	a	regulatory	liability,	we	would	be	required	to	remove	the	
associated	regulatory	assets	and	liabilities	from	our	consolidated	balance	sheet	and	recognize	in	the	consolidated	statement	of	income	as	an	
expense	or	income	item	in	the	period	in	which	this	accounting	treatment	is	no	longer	applicable.			

PENSION	AND	OTHER	POSTRETIREMENT	BENEFITS	OBLIGATIONS	AND	COSTS
Pension	and	postretirement	benefit	liabilities	and	expenses	are	determined	by	actuaries	using	assumptions	about	the	discount	rate,	expected	
return	on	plan	assets,	rate	of	compensation	increase	and	healthcare	cost-trend	rates.	See	Note	10	to	our	consolidated	financial	statements	
included	in	this	report	on	Form	10-K	for	additional	information	on	our	pension	and	postretirement	benefit	plans	and	related	assumptions.

These	benefits,	for	any	individual	employee,	can	be	earned	and	related	expenses	can	be	recognized	and	a	liability	accrued	over	periods	of	up	to	30	
or	more	years.	These	benefits	can	be	paid	out	for	up	to	40	or	more	years	after	an	employee	retires.	Estimates	of	liabilities	and	expenses	related	to	
these	benefits	are	among	our	most	critical	accounting	estimates.	Although	deferral	and	amortization	of	fluctuations	in	actuarially	determined	
benefit	obligations	and	expenses	are	provided	for	when	actual	results	on	a	year-to-year	basis	deviate	from	long-range	assumptions,	compensation	
increases	and	healthcare	cost	increases	or	a	reduction	in	the	discount	rate	applied	from	one	year	to	the	next	can	significantly	increase	our	benefit	
expenses	in	the	year	of	the	change.	Also,	a	reduction	in	the	expected	rate	of	return	on	pension	plan	assets	in	our	funded	pension	plan	or	realized	
rates	of	return	on	plan	assets	that	are	well	below	assumed	rates	of	return	or	an	increase	in	the	anticipated	life	expectancy	of	plan	participants	
could	result	in	significant	increases	in	recognized	pension	benefit	expenses	in	the	year	of	the	change	or	for	many	years	thereafter	because	actuarial	
losses	can	be	amortized	over	the	average	remaining	service	lives	of	active	employees.

We	estimate	the	discount	rate	through	the	use	of	a	hypothetical	bond	portfolio	method,	which	incorporates	yields	on	a	collection	of	high	credit	
quality	bonds	that	produce	cash	flows	similar	to	our	anticipated	future	benefit	payments.	We	estimate	the	assumed	long-term	rate	of	return	on	

34

plan	assets	based	on	asset	category	studies	using	historical	market	returns	and	volatility	rates	with	forward	looking	estimates	based	on	existing	and	
forecasted	future	market	conditions.

At	December	31,	2021,	we	set	the	discount	rate	used	to	measure	our	pension	plan	obligations	at	3.03%	and	at	3.01%	to	measure	postretirement	
healthcare	obligations,	a	25	and	26	basis	point	increase,	respectively,	from	the	estimates	used	at	December	31,	2020.	Our	estimates	used	to	
determine	benefit	cost	for	2021	included	a	discount	rate	of	2.78%	for	pension	benefits	and	2.75%	for	postretirement	healthcare	costs,	a	69	and	68	
basis	point	decrease,	respectively,	from	2020	estimates.	In	addition,	we	estimated	our	assumed	rate	of	return	on	pension	assets	to	be	6.51%	for	
2021,	a	37	basis	point	decrease	from	our	2020	estimate.	

The	following	table	summarizes	the	impact	on	2021	pension	and	postretirement	costs	for	a	0.25	increase	or	decrease,	holding	all	other	variables	
constant,	on	certain	key	assumptions:

For	2022,	we	expect	pension	benefit	cost	for	our	pension	plan	to	be	$3.0	million	compared	to	$7.7	million	in	2021,	as	the	amortization	of	actuarial	
losses	is	reduced	in	2022	following	actuarial	gains	recognized	as	of	December	31,	2021.	The	estimated	discount	rate	used	to	determine	annual	
benefit	cost	accruals	increased	from	2.78%	in	2021	to	3.03%	in	2022.	The	assumed	rate	of	return	on	pension	plan	assets	is	6.30%	for	2022	
compared	with	6.51%	for	2021.	

Subsequent	increases	or	decreases	in	actual	rates	of	return	on	plan	assets	over	assumed	rates,	increases	or	decreases	in	the	discount	rate,	
increases	in	future	compensation	levels,	and	increases	in	retiree	healthcare	cost	inflation	rates	could	significantly	change	projected	costs.

We	believe	the	estimates	made	for	our	pension	and	other	postretirement	benefits	are	reasonable	based	on	the	information	that	is	known	at	the	
point	in	time	the	estimates	are	made.	These	estimates	and	assumptions	are	subject	to	a	number	of	variables	and	are	subject	to	change.

GOODWILL	IMPAIRMENT
Goodwill	is	required	to	be	evaluated	annually	for	impairment	and	more	frequently	as	events	or	circumstances	require.	Goodwill	is	tested	for	
impairment	at	the	reporting	unit	level.	We	have	identified	two	reporting	units	which	carry	a	material	amount	of	goodwill.

The	goodwill	impairment	test	is	a	single-step	quantitative	assessment	which	compares	the	estimated	fair	value	of	the	reporting	unit	to	its	carrying	
value.	An	impairment	charge	is	recognized	if	the	carrying	amount	exceeds	the	estimated	fair	value	in	an	amount	that	is	equal	to	the	excess	but	
limited	to	the	amount	of	recorded	goodwill	of	the	reporting	unit.	An	optional	qualitative	impairment	assessment	may	be	performed	prior	to	and	
may	eliminate	the	need	to	perform	the	quantitative	assessment.

Estimating	the	fair	value	of	a	reporting	unit	under	the	quantitative	impairment	method	requires	significant	judgments	and	estimates.	We	estimate	
the	fair	value	of	our	reporting	units	primarily	using	an	income	approach,	which	includes	a	discounted	cash	flow	methodology	to	arrive	at	a	fair	value	
estimate	by	determining	the	present	value	of	projected	future	cash	flows	over	a	specified	period	plus	a	terminal	value	to	reflect	cash	flows	beyond	
the	projection	period.	The	discount	rate	applied	to	the	estimated	future	cash	flows	reflects	our	estimate	of	the	weighted-average	cost	of	capital	of	
comparable	entities.	To	supplement	our	income	approach,	we	reference	various	market	indications	of	fair	value,	where	available,	and	include	fair	
value	estimates	using	multiples	derived	from	comparable	enterprise	values	to	EBITDA,	comparable	price	earnings	ratios	and,	if	available,	
comparable	sales	transactions	for	comparative	peer	companies.

Our	discounted	cash	flow	methodology	incorporates	significant	estimates,	which	include	assumptions	of	future	operating	results	and	cash	flows,	
which	are	impacted	by	economic	and	industry	conditions,	the	amount	and	timing	of	estimated	capital	expenditures,	an	estimated	terminal	growth	
rate	and	the	selection	of	an	appropriate	weighted-average	cost	of	capital,	among	others.	

Our	goodwill	impairment	testing	performed	in	the	fourth	quarter	of	2021	indicated	no	impairment	was	present	for	either	reporting	unit	and	the	
estimated	fair	value	of	each	reporting	unit	substantially	exceeded	the	respective	carrying	value.	As	part	of	our	testing	we	perform	various	
sensitivity	analyses	to	understand	if	our	conclusions	are	sensitive	to	changes	in	certain	assumptions.	A	1%	decrease	in	projected	operating	
revenues,	a	one	hundred	basis	point	decrease	in	projected	gross	profit	margins	and	a	twenty	five	basis	point	increase	in	the	discount	rate	would	
not	lead	to	a	goodwill	impairment	charge	for	either	reporting	unit.	

We	believe	the	estimates	and	assumptions	used	in	our	impairment	assessments	are	reasonable	and	based	on	the	best	information	available.	
However,	these	estimates	and	assumptions	inherently	include	a	degree	of	uncertainty.	Significant	adverse	changes	in	our	expectations	for	any	of	
these	estimates	could	result	in	an	impairment	charge	in	a	future	period	which	may	materially	impact	our	operating	results	and	financial	position.

ITEM	7A. QUANTITATIVE	AND	QUALITATIVE	DISCLOSURES	ABOUT	MARKET	RISK

Market	risk	is	the	potential	loss	arising	from	adverse	changes	in	market	rates	and	prices.	We	are	primarily	exposed	to	interest	rate	and	commodity	
price	risk.

Commodity	Price	Risk
Our	Electric	segment	business	is	exposed	to	market	risk	arising	from	changes	in	commodity	prices	for	wholesale	energy	and	natural	gas.	OTP	
purchases	energy	in	the	wholesale	market	to	supplement	its	own	electricity	generation	and	to	respond	to	changes	in	demand	and	variability	in	
generating	plant	output.	In	addition,	OTP	procures	natural	gas	as	a	fuel	source	for	its	combustion	turbine	peaking	facilities.	OTP's	exposure	to	price	
risk	for	these	commodities	is	largely	mitigated	by	the	current	ratemaking	process	and	regulatory	framework,	which	generally	allows	recovery	of	
purchased	power	and	fuel	costs	from	our	electric	customers.	

OTP,	where	prudent,	seeks	to	further	manage	its	exposure	to	commodity	price	variability	and	reduce	volatility	in	prices	for	its	retail	customers	
through	the	use	of	derivative	instruments,	primarily	financial	swap	agreements.	OTP	does	not	engage	in	derivative	and	hedging	activities	for	trading	
purposes.	As	of	December	31,	2021,	OTP	was	party	to	financial	swap	agreements	with	an	aggregate	notional	amount	of	263,400	megawatt-hours	of	
electricity	with	various	settlement	dates	throughout	2022.	As	of	December	31,	2021,	the	aggregate	fair	value	of	these	instruments	was	$6.2	million.	
Holding	other	variables	constant,	a	ten	percent	change	in	energy	prices	would	have	had	an	approximate	$1.5	million	impact	on	the	fair	value	of	
these	instruments.	

Our	Manufacturing	segment	businesses	are	exposed	to	market	risk	arising	from	changes	in	commodity	prices	for	certain	raw	material	inputs,	
including	steel,	aluminum,	and	polystyrene	and	other	plastics	resins.	We	attempt	to	manage	commodity	price	risk	by	passing	changes	in	the	cost	of	
these	input	materials	on	to	our	customers.	If	our	efforts	to	manage	commodity	price	risk	are	unsuccessful,	the	operating	revenues	and	earnings	of	
our	Manufacturing	segment	could	be	impacted.

Our	Plastics	segment	businesses	are	exposed	to	market	risk	arising	from	changes	in	prices	for	PVC	resin,	the	primary	raw	material	commodity	used	
to	manufacture	PVC	pipe.	The	PVC	pipe	industry	as	a	whole	is	highly	sensitive	to	volatility	in	PVC	resin	prices,	with	frequent	adjustments	to	PVC	
pipe	sale	prices	to	reflect	volatility	in	PVC	resin	costs.	Historically,	when	resin	prices	are	rising	or	stable,	sales	volumes	have	been	higher.	In	contrast,	
when	resin	prices	are	falling,	sales	volumes	have	been	lower.	Due	to	the	commodity	nature	of	PVC	resin	and	dynamic	supply	and	demand	factors	
worldwide,	gross	profit	margins	can	fluctuate	significantly	from	period	to	period.

We	do	not	engage	in	any	hedging	activities	within	our	Manufacturing	and	Plastics	segments	to	manage	our	commodity	price	risk.

Interest	Rate	Risk
Our	exposure	to	interest	rate	risk	arises	from	outstanding	short-term	debt	which	is	subject	to	variable	rates	of	interest	based	on	benchmark	
interest	rates,	primarily	LIBOR.	As	of	December	31,	2021	and	2020,	we	had	$91.2	million	and	$81.0	million	of	short-term	debt	outstanding.	Holding	
other	variables	constant,	a	one	percentage	point	change	in	interest	rates	would	have	had	an	approximate	$1.0	million	impact	to	interest	charges	in	
2021	based	on	our	average	outstanding	short-term	debt	during	the	year.	

All	of	our	outstanding	long-term	debt	obligations	as	of	December	31,	2021	and	2020	had	fixed	interest	rates	and	thus	were	not	subject	to	interest	
rate	risk.	We	manage	our	interest	rate	risk	through	the	issuance	of	fixed-rate	debt	with	varying	maturities,	by	limiting	the	amount	of	variable	
interest	rate	debt	and	the	utilization	of	short-term	borrowings	to	allow	flexibility	in	the	timing	and	placement	of	long-term	debt.

We	have	not	used	hedging	instruments	to	manage	interest	risk	arising	from	our	portfolio	of	borrowings.	We	maintain	a	ratio	of	fixed-rate	debt	to	
total	debt	within	a	certain	range.	It	is	our	policy	to	enter	into	interest	rate	transactions	and	other	financial	instruments	only	to	the	extent	
considered	necessary	to	meet	our	stated	objectives.	We	do	not	enter	into	interest	rate	transactions	for	speculative	or	trading	purposes.

FINANCIAL	STATEMENTS

REPORT	OF	INDEPENDENT	REGISTERED	PUBLIC	ACCOUNTING	FIRM

To	the	Shareholders	and	the	Board	of	Directors	of	Otter	Tail	Corporation

Opinions	on	the	Financial	Statements	and	Internal	Control	over	Financial	Reporting

We	have	audited	the	accompanying	consolidated	balance	sheets	of	Otter	Tail	Corporation	and	subsidiaries	(the	“Company”)	as	of	December	31,	
2021	and	2020,	the	related	consolidated	statements	of	income,	comprehensive	income,	shareholders’	equity,	and	cash	flows	for	each	of	the	three	
years	in	the	period	ended	December	31,	2021,	and	the	related	notes	and	the	schedules	listed	in	the	Index	at	Item	15	(collectively	referred	to	as	the	
“financial	statements”).	We	also	have	audited	the	Company’s	internal	control	over	financial	reporting	as	of	December	31,	2021,	based	on	criteria	
established	in	Internal	Control—Integrated	Framework	(2013)	issued	by	the	Committee	of	Sponsoring	Organizations	of	the	Treadway	Commission	
(COSO).

In	our	opinion,	the	financial	statements	referred	to	above	present	fairly,	in	all	material	respects,	the	financial	position	of	the	Company	as	of	
December	31,	2021	and	2020,	and	the	results	of	its	operations	and	its	cash	flows	for	each	of	the	three	years	in	the	period	ended	December	31,	
2021,	in	conformity	with	accounting	principles	generally	accepted	in	the	United	States	of	America.	Also,	in	our	opinion,	the	Company	maintained,	in	
all	material	respects,	effective	internal	control	over	financial	reporting	as	of	December	31,	2021,	based	on	the	criteria	established	in	Internal	
Control—Integrated	Framework	(2013)	issued	by	COSO.

Basis	for	Opinions

The	Company’s	management	is	responsible	for	these	financial	statements,	for	maintaining	effective	internal	control	over	financial	reporting,	and	
for	its	assessment	of	the	effectiveness	of	internal	control	over	financial	reporting,	included	in	the	accompanying	Management’s	Report	Regarding	
Internal	Controls	Over	Financial	Reporting.	Our	responsibility	is	to	express	an	opinion	on	these	financial	statements	and	an	opinion	on	the	
Company’s	internal	control	over	financial	reporting	based	on	our	audits.	We	are	a	public	accounting	firm	registered	with	the	Public	Company	
Accounting	Oversight	Board	(United	States)	(PCAOB)	and	are	required	to	be	independent	with	respect	to	the	Company	in	accordance	with	the	U.S.	
federal	securities	laws	and	the	applicable	rules	and	regulations	of	the	Securities	and	Exchange	Commission	and	the	PCAOB.

We	conducted	our	audits	in	accordance	with	the	standards	of	the	PCAOB.	Those	standards	require	that	we	plan	and	perform	the	audit	to	obtain	
reasonable	assurance	about	whether	the	financial	statements	are	free	of	material	misstatement,	whether	due	to	error	or	fraud,	and	whether	
effective	internal	control	over	financial	reporting	was	maintained	in	all	material	respects.

Our	audits	of	the	financial	statements	included	performing	procedures	to	assess	the	risks	of	material	misstatement	of	the	financial	statements,	
whether	due	to	error	or	fraud,	and	performing	procedures	to	respond	to	those	risks.	Such	procedures	included	examining,	on	a	test	basis,	evidence	
regarding	the	amounts	and	disclosures	in	the	financial	statements.	Our	audits	also	included	evaluating	the	accounting	principles	used	and	
significant	estimates	made	by	management,	as	well	as	evaluating	the	overall	presentation	of	the	financial	statements.	Our	audit	of	internal	control	
over	financial	reporting	included	obtaining	an	understanding	of	internal	control	over	financial	reporting,	assessing	the	risk	that	a	material	weakness	
exists,	and	testing	and	evaluating	the	design	and	operating	effectiveness	of	internal	control	based	on	the	assessed	risk.	Our	audits	also	included	
performing	such	other	procedures	as	we	considered	necessary	in	the	circumstances.	We	believe	that	our	audits	provide	a	reasonable	basis	for	our	
opinions.

Definition	and	Limitations	of	Internal	Control	over	Financial	Reporting

A	company’s	internal	control	over	financial	reporting	is	a	process	designed	to	provide	reasonable	assurance	regarding	the	reliability	of	financial	
reporting	and	the	preparation	of	financial	statements	for	external	purposes	in	accordance	with	generally	accepted	accounting	principles.	A	
company’s	internal	control	over	financial	reporting	includes	those	policies	and	procedures	that	(1)	pertain	to	the	maintenance	of	records	that,	in	
reasonable	detail,	accurately	and	fairly	reflect	the	transactions	and	dispositions	of	the	assets	of	the	company;	(2)	provide	reasonable	assurance	that	
transactions	are	recorded	as	necessary	to	permit	preparation	of	financial	statements	in	accordance	with	generally	accepted	accounting	principles,	
and	that	receipts	and	expenditures	of	the	company	are	being	made	only	in	accordance	with	authorizations	of	management	and	directors	of	the	
company;	and	(3)	provide	reasonable	assurance	regarding	prevention	or	timely	detection	of	unauthorized	acquisition,	use,	or	disposition	of	the	
company’s	assets	that	could	have	a	material	effect	on	the	financial	statements.

Because	of	its	inherent	limitations,	internal	control	over	financial	reporting	may	not	prevent	or	detect	misstatements.	Also,	projections	of	any	
evaluation	of	effectiveness	to	future	periods	are	subject	to	the	risk	that	controls	may	become	inadequate	because	of	changes	in	conditions,	or	that	
the	degree	of	compliance	with	the	policies	or	procedures	may	deteriorate.

Critical	Audit	Matters

The	critical	audit	matters	communicated	below	are	matters	arising	from	the	current-period	audit	of	the	financial	statements	that	were	
communicated	or	required	to	be	communicated	to	the	audit	committee	and	that	(1)	relate	to	accounts	or	disclosures	that	are	material	to	the	
financial	statements	and	(2)	involved	our	especially	challenging,	subjective,	or	complex	judgments.	The	communication	of	critical	audit	matters	
does	not	alter	in	any	way	our	opinion	on	the	financial	statements,	taken	as	a	whole,	and	we	are	not,	by	communicating	the	critical	audit	matters	
below,	providing	separate	opinions	on	the	critical	audit	matters	or	on	the	accounts	or	disclosures	to	which	they	relate.

Rate	and	Regulatory	Matters—Impact	of	Rate	Regulation	on	the	Financial	Statements—Refer	to	Notes	1,	and	5	to	the	financial	statements.

Critical	Audit	Matter	Description

The	Company’s	regulated	Electric	segment	accounts	for	the	financial	effects	of	regulation	in	accordance	with	ASC	980,	Regulated	Operations.	This	
guidance	allows	for	the	recording	of	a	regulatory	asset	or	liability	for	certain	costs	or	credits	which	otherwise	would	be	recognized	in	the	statement	
of	income	or	comprehensive	income	based	on	an	expectation	that	the	cost	will	be	recovered	or	returned	in	future	rates.	This	guidance	also	
provides	for	adjustments	to	rates	outside	of	a	general	rate	case	proceeding	to	encourage	or	incentivize	investments	in	certain	areas	such	as	
conservation,	renewable	energy,	pollution	reduction	or	control,	improved	infrastructure	of	the	transmission	grid	or	other	programs	that	provide	
benefits	to	the	general	public	under	public	policy,	laws	or	regulations.

The	Company	is	subject	to	rate	regulation	by	state	and	federal	regulatory	agencies	(collectively,	the	“Commissions”),	which	have	jurisdiction	with	
respect	to	the	rates	of	electric	distribution	companies	in	Minnesota,	North	Dakota	and	South	Dakota.	The	Company	assesses	the	probability	of	
recovery	of	regulatory	assets	and	the	obligations	arising	from	regulatory	liabilities	on	a	quarterly	basis.	Probability	estimates	incorporate	numerous	
factors,	including	recent	rate	making	decisions,	historical	precedents	for	similar	matters,	the	regulatory	environments	in	which	the	Company	
operates,	and	the	impact	these	incurred	costs	may	have	on	customers.

Accounting	for	the	economics	of	rate	regulation	impacts	multiple	financial	statement	line	items	and	disclosures,	such	as	property,	plant,	and	
equipment,	regulatory	assets	and	liabilities,	operating	revenues	and	expenses,	depreciation	expense,	income	taxes	and	multiple	disclosures	in	the	
notes	to	the	financial	statements.	There	is	a	risk	that	the	Commissions	will	not	approve	full	recovery	of	the	costs	of	providing	utility	service	or	full	
recovery	of	all	amounts	invested	in	the	utility	business	and	a	reasonable	return	on	that	investment.	As	a	result,	we	identified	the	impact	of	rate	
regulation	as	a	critical	audit	matter	due	to	the	significant	judgments	made	by	management	to	support	its	assertions	about	impacted	account	
balances	and	disclosures	and	the	high	degree	of	subjectivity	involved	in	assessing	the	impact	of	future	regulatory	orders	on	the	financial	
statements.	Management	judgments	include	assessing	the	likelihood	of	(1)	recovery	in	future	rates	of	incurred	costs,	(2)	a	disallowance	of	capital	
expenditures	or	operating	costs	that	management	believes	were	prudently	incurred,	and	(3)	a	refund	to	customers.	Given	that	management’s	
accounting	judgements	are	based	on	assumptions	about	the	outcome	of	future	decisions	by	the	Commissions,	auditing	these	judgments	required	
specialized	knowledge	of	accounting	for	rate	regulation	and	the	rate	setting	process	due	its	inherent	complexities.

How	the	Critical	Audit	Matter	Was	Addressed	in	the	Audit

Our	audit	procedures	related	to	the	uncertainty	of	future	decisions	by	the	Commissions	included	the	following,	among	others:

• We	tested	the	effectiveness	of	management’s	controls	over	the	evaluation	of	the	likelihood	of	(1)	the	recovery	in	future	rates	of	costs	incurred	
as	property,	plant,	and	equipment	and	deferred	as	regulatory	assets,	and	(2)	a	refund	or	a	future	reduction	in	rates	that	should	be	reported	as	
regulatory	liabilities.	We	also	tested	the	effectiveness	of	management’s	controls	over	the	initial	recognition	of	amounts	as	property,	plant,	and	
equipment;	regulatory	assets	or	liabilities;	and	the	monitoring	and	evaluation	of	regulatory	developments	that	may	affect	the	likelihood	of	
recovering	costs	in	future	rates	or	of	a	future	reduction	in	rates.

• We	evaluated	the	Company’s	disclosures	related	to	the	impacts	of	rate	regulation,	including	the	balances	recorded	and	regulatory	

developments.

• We	read	relevant	regulatory	orders	issued	by	the	Commissions	for	the	Company,	regulatory	statutes,	interpretations,	procedural	

memorandums,	filings	made	by	interveners,	and	other	publicly	available	information	to	assess	the	likelihood	of	recovery	in	future	rates	or	of	a	
future	reduction	in	rates	based	on	precedents	of	the	Commissions’	treatment	of	similar	costs	under	similar	circumstances.	We	evaluated	the	
external	information	and	compared	to	management’s	recorded	regulatory	asset	and	liability	balances	for	completeness.

• We	inquired	of	management	about	property,	plant,	and	equipment	that	may	be	abandoned.	We	inspected	the	capital-projects	budget	and	

construction-in-process	listings	and	inquired	of	management	to	identify	projects	that	are	designed	to	replace	assets	that	may	be	retired	prior	
to	the	end	of	the	useful	life.	We	inspected	minutes	of	the	board	of	directors	and	regulatory	orders	and	other	filings	with	the	Commissions	to	
identify	any	evidence	that	may	contradict	management’s	assertion	regarding	probability	of	an	abandonment.

• We	compared	actual	spend	for	projects	that	have	been	capitalized	to	property,	plant,	and	equipment	to	budget.	We	evaluated	regulatory	

filings	for	any	evidence	that	intervenors	are	challenging	full	recovery	of	the	cost	of	any	capital	projects.

• We	obtained	an	analysis	from	management	and	letters	from	internal	and	external	legal	counsel,	as	appropriate,	regarding	probability	of	

recovery	for	regulatory	assets	or	refund	or	future	reduction	in	rates	for	regulatory	liabilities	not	yet	addressed	in	a	regulatory	order	to	assess	
management’s	assertion	that	amounts	are	probable	of	recovery	or	a	future	reduction	in	rates.

Goodwill—Manufacturing	Reporting	Unit—Refer	to	Notes	1	and	7	to	the	financial	statements

Critical	Audit	Matter	Description

The	Company’s	evaluation	of	goodwill	for	impairment	involves	the	comparison	of	the	fair	value	of	each	reporting	unit	to	its	carrying	value.	The	
Company	performs	quantitative	assessments	of	goodwill	annually	as	of	December	31	(the	“measurement	date”)	and	more	frequently	as	events	or	
circumstances	require.	The	Company	estimates	the	fair	value	of	its	Manufacturing	reporting	unit	by	primarily	using	the	discounted	cash	flow	model.	
The	determination	of	the	fair	value	using	the	discounted	cash	flow	model	requires	management	to	make	significant	estimates	and	assumptions	
related	to	forecasts	of	future	operating	results	and	cash	flows.	The	Manufacturing	reporting	unit’s	operating	results	and	cash	flows	are	sensitive	to	
changes	in	demand.	The	goodwill	balance	was	$37.6	million	as	of	December	31,	2021,	of	which	$18.3	million	relates	to	the	Manufacturing	reporting	
unit.	The	fair	value	of	the	Manufacturing	reporting	unit	exceeded	its	carrying	value	as	of	the	measurement	date	and,	therefore,	no	impairment	was	
recognized.

38

We	identified	goodwill	for	the	Manufacturing	reporting	unit	as	a	critical	audit	matter	because	of	the	significant	judgments	made	by	management	to	
estimate	its	fair	value	and	the	difference	between	its	fair	value	and	carrying	value	and	the	sensitivity	of	the	Manufacturing	reporting	unit’s	
operations	to	changes	in	demand.	This	required	a	high	degree	of	auditor	judgment	and	an	increased	extent	of	effort	when	performing	audit	
procedures	to	evaluate	the	reasonableness	of	management’s	estimates	and	assumptions	related	to	forecasts	of	future	operating	results	and	cash	
flows.

How	the	Critical	Audit	Matter	Was	Addressed	in	the	Audit

Our	audit	procedures	related	to	forecasts	of	future	operating	results	and	cash	flows	used	by	management	to	estimate	the	fair	value	of	the	
Manufacturing	reporting	unit	included	the	following,	among	others:

• We	tested	the	effectiveness	of	controls	over	management’s	goodwill	impairment	evaluation,	including	those	over	the	determination	of	the	fair	

value	of	the	Manufacturing	reporting	unit,	such	as	controls	related	to	forecasts	of	future	operating	results	and	cash	flows.

• We	evaluated	management’s	ability	to	accurately	forecast	future	operating	results	and	cash	flows	by	comparing	actual	results	to	

management’s	historical	forecasts.

• We	evaluated	the	reasonableness	of	management’s	operating	results	and	cash	flow	forecasts	by	comparing	the	forecasts	to:

–

–

–

Historical	operating	results	and	cash	flows.

Internal	communications	between	management	and	the	Board	of	Directors.

Forecasted	information	included	in	Company	press	releases	as	well	as	in	analyst	and	industry	reports	for	the	Company	and	certain	of	its	
peer	companies.

OTTER	TAIL	CORPORATION
NOTES	TO	CONSOLIDATED	FINANCIAL	STATEMENTS

1.	Summary	of	Significant	Accounting	Policies

Overview
Otter	Tail	Corporation	(OTC)	and	its	subsidiaries	(collectively,	the	"Company",	"us",	"our"	or	"we")	form	a	diverse,	multi-platform	business	
consisting	of	a	vertically	integrated,	regulated	utility	with	generation,	transmission	and	distribution	facilities	complemented	by	manufacturing	
businesses	providing	metal	fabrication	for	custom	machine	parts	and	metal	components,	manufacturing	of	extruded	and	thermoformed	plastic	
products,	and	manufacturing	of	PVC	pipe	products.	We	classify	our	business	into	three	segments:	Electric,	Manufacturing	and	Plastics.	Note	2	
includes	an	additional	description	of	the	segments	and	financial	information	regarding	each	segment.

Principles	of	Consolidation
These	consolidated	financial	statements	are	presented	in	accordance	with	U.S.	generally	accepted	accounting	principles	and	include	the	accounts	
of	OTC	and	its	wholly	owned	subsidiaries.	All	intercompany	balances	and	transactions	have	been	eliminated	in	consolidation	except,	as	applicable,	
profits	on	sales	to	our	regulated	electric	utility	company	from	our	nonregulated	businesses,	which	is	in	accordance	with	the	accounting	
requirements	of	regulated	operations.

Use	of	Estimates
We	use	estimates	based	on	the	best	information	available	in	recording	transactions	and	balances	resulting	from	business	operations.	As	better	
information	becomes	available,	or	actual	amounts	are	known,	the	recorded	estimates	are	revised.	Consequently,	operating	results	can	be	affected	
by	revisions	to	prior	accounting	estimates.

Reclassifications
Certain	reclassifications	of	amounts	previously	reported	have	been	made	to	the	accompanying	consolidated	balance	sheets	and	statements	of	cash	
flows	to	maintain	consistency	and	comparability	between	periods	presented.	The	reclassifications	had	no	impact	on	previously	reported	current	
assets,	total	assets,	current	liabilities,	noncurrent	liabilities	and	deferred	credits,	shareholders'	equity,	net	cash	provided	by	operating	activities,	net	
cash	used	in	investing	activities,	net	cash	(used	in)	provided	by	financing	activities,	or	cash	and	cash	equivalents.

Regulatory	Accounting
Our	regulated	electric	utility	company,	Otter	Tail	Power	Company	(OTP),	is	subject	to	regulation	of	rates	and	other	matters	by	state	utility	
commissions	in	Minnesota,	North	Dakota	and	South	Dakota	and	by	the	Federal	Energy	Regulatory	Commission	(FERC)	for	certain	interstate	
operations.	OTP	accounts	for	the	financial	effects	of	regulation	in	accordance	with	accounting	guidance	for	regulated	operations.	This	guidance	
allows	for	the	recording	of	a	regulatory	asset	for	certain	costs	which	otherwise	would	be	recognized	in	the	statement	of	income	or	comprehensive	
income	based	on	an	expectation	that	the	cost	will	be	recovered	in	future	rates.	This	guidance	also	requires	the	recording	of	a	regulatory	liability	for	
certain	credits	which	would	otherwise	be	recognized	in	the	statement	of	income	or	comprehensive	income	based	on	an	expectation	that	the	
amount	will	be	returned	to	customers	in	future	rates.	Amounts	recorded	as	regulatory	assets	and	regulatory	liabilities	are	generally	recognized	in	
the	statements	of	income	at	the	time	they	are	reflected	in	customer	rates.	In	the	event	OTP	ceases	to	meet	the	criteria	to	apply	the	guidance	for	
regulated	operations,	the	regulatory	assets	and	liabilities	that	no	longer	meet	such	criteria	would	be	removed	from	the	consolidated	balance	sheet	
and	included	in	the	consolidated	statement	of	income	as	an	expense	or	income	item	in	the	period	in	which	the	application	of	this	guidance	ceases.

Cash	Equivalents
We	consider	all	highly	liquid	debt	instruments	purchased	with	maturity	of	90	days	or	less	to	be	cash	equivalents.

Revenue	from	Contracts	with	Customers
Due	to	our	diverse	business	operations,	the	recognition	of	revenue	from	contracts	with	customers	depends	on	the	product	produced	and	sold	or	
service	performed.	We	recognize	revenue	from	contracts	with	customers	at	prices	that	are	fixed	or	determinable	as	evidenced	by	an	agreement	
with	the	customer,	when	we	have	met	our	performance	obligation	under	the	contract	and	it	is	probable	that	we	will	collect	the	amount	to	which	
we	are	entitled	in	exchange	for	the	goods	or	services	transferred	or	to	be	transferred	to	the	customer.	Depending	on	the	product	produced	and	
sold	or	service	performed	and	the	terms	of	the	agreement	with	the	customer,	we	recognize	revenue	either	over	time,	in	the	case	of	delivery	or	
transmission	of	electricity	or	related	services	or	the	production	and	storage	of	certain	custom-made	products,	or	at	a	point	in	time	for	the	delivery	
of	standardized	products	and	other	products	made	to	customer	specifications	where	the	terms	of	the	contract	require	transfer	of	the	completed	
product.	Provisions	for	sales	returns,	early	payment	terms	discounts,	and	volume-based	variable	pricing	incentives	are	recorded	as	reductions	to	
revenue	at	the	time	revenue	is	recognized	based	on	customer	history,	historical	information	and	current	trends.	We	include	revenues	received	for	
shipping	and	handling	in	operating	revenues.	Expenses	paid	for	shipping	and	handling	are	recorded	as	part	of	cost	of	goods	sold.	Sales	or	other	
taxes	collected	from	customers	are	excluded	from	operating	revenues.		

Electric	Segment	Revenues.	Most	Electric	segment	revenues	are	earned	from	the	generation,	transmission	and	sale	of	electricity	to	retail	
customers	at	rates	approved	by	state	regulatory	commissions.	OTP	also	earns	revenue	from	the	transmission	of	electricity	for	others	over	the	
transmission	assets	it	owns	separately,	or	jointly	with	other	transmission	service	providers,	under	rate	tariffs	established	by	the	independent	
transmission	system	operator	and	approved	by	the	FERC.	A	third	source	of	revenue	for	OTP	comes	from	the	generation	and	sale	of	electricity	to	
wholesale	customers	at	contract	or	market	rates.	Revenues	from	all	these	sources	meet	the	criteria	to	be	classified	as	revenue	from	contracts	with	
customers	and	are	recognized	over	time	as	energy	is	delivered	or	transmitted.	Revenue	is	recognized	based	on	the	metered	quantity	of	electricity	
delivered	or	transmitted	at	the	applicable	rates.	For	electricity	delivered	and	consumed	after	a	meter	is	read	but	prior	to	the	end	of	the	reporting	
period,	OTP	records	revenue	and	an	unbilled	receivable	based	on	estimates	of	the	kilowatt-hours	(kwh)	of	energy	delivered	to	the	customer.

45

Manufacturing	Segment	Revenues.	Our	Manufacturing	segment	businesses	earn	revenue	predominantly	from	the	production	and	delivery	of	
custom-made	or	standardized	parts	to	customers	across	several	industries	and	certain	businesses	also	earn	revenue	from	the	production	and	sale	
of	tools	and	dies	to	other	manufacturers.	For	the	production	and	delivery	of	standardized	products	and	other	products	made	to	customer	
specifications	where	the	terms	of	the	contract	require	transfer	of	the	completed	product,	we	have	met	our	performance	obligation	and	recognize	
revenue	at	the	point	in	time	when	the	product	is	shipped.	At	this	point	we	have	no	further	obligation	to	provide	services	related	to	such	products.	
The	shipping	terms	used	in	these	transactions	are	FOB	shipping	point.

Plastics	Segment	Revenues.	Our	Plastics	segment	businesses	earn	revenue	predominantly	from	the	sale	and	delivery	of	standardized	PVC	pipe	
products	produced	at	their	manufacturing	facilities.	Revenue	from	the	sale	of	these	products	is	recognized	at	the	point	in	time	when	the	product	is	
shipped	as	there	is	no	further	obligation	to	provide	services	related	to	such	products	and	the	shipping	terms	are	FOB	shipping	point.	We	have	one	
customer	within	our	Plastics	segment	for	which	we	produce	and	store	a	product	made	to	the	customer’s	specifications	and	design	under	a	build	
and	hold	agreement.	For	sales	to	this	customer,	we	recognize	revenue	as	the	custom-made	product	is	produced,	adjusting	the	amount	of	revenue	
for	volume	rebate	variable	pricing	considerations	we	expect	the	customer	will	earn	and	applicable	early	payment	discounts	we	expect	the	customer	
will	take.	Ownership	of	the	pipe	transfers	to	the	customer	prior	to	delivery	and	we	are	paid	a	negotiated	fee	for	storage	of	the	pipe.	Revenue	for	
storage	of	the	pipe	is	also	recognized	over	time	as	the	pipe	is	stored.

Alternative	Revenue
In	addition	to	recognizing	revenue	from	contracts	with	customers,	our	Electric	segment	business	also	records	revenue	under	alternative	revenue	
program	(ARPs)	requirements.	Certain	rate	rider	mechanisms	qualify	as	ARP	revenues	as	they	provide	for	adjustments	to	rates	outside	of	a	general	
rate	case	proceeding	to	encourage	or	incentivize	investments	in	certain	areas	such	as	conservation,	renewable	energy,	pollution	reduction	or	
control,	improved	infrastructure	of	the	transmission	grid	or	other	programs	that	provide	benefits	to	the	general	public	under	public	policy,	laws	or	
regulations.	ARP	riders	generally	provide	for	the	recovery	of	specified	costs	and	investments	and	include	an	incentive	component	to	provide	the	
regulated	utility	with	a	return	on	amounts	invested.		

We	accrue	ARP	revenue	on	the	basis	of	cost	incurred,	investments	made	and	returns	on	those	investments	that	qualify	for	recovery	through	
established	riders.	ARP	revenue	is	disclosed	separately	from	revenue	from	contracts	with	customers	and	we	have	elected	to	report	ARP	revenue	on	
a	net	basis,	whereby	amounts	initially	recorded	as	ARP	revenue	in	a	period	are	presented	net	of	the	reversal	of	amounts	previously	recognized	as	
ARP	revenue	that	are	reclassified	and	recorded	as	revenue	from	contracts	with	customers	when	such	amounts	are	included	in	the	price	of	
electricity	to	customers.

Receivables	and	Allowance	for	Credit	Losses
We	grant	credit	to	our	customers	in	the	normal	course	of	business	with	repayment	terms	generally	ranging	from	30	to	90	days	after	the	invoice	
date.	Late	fees	are	assessed	on	certain	receivables	once	they	are	30	days	past	due.	Unbilled	receivables	represent	estimates	of	energy	delivered	to	
customers	but	not	yet	billed.	

Receivables	are	stated	at	the	billed	or	estimated	unbilled	amount	less	an	allowance	for	estimated	credit	losses.	An	allowance	for	credit	losses	is	
established	based	on	losses	expected	to	occur	over	the	contractual	life	of	the	receivable.	We	estimate	an	allowance	for	credit	losses	on	our	trade	
and	unbilled	receivables	by	evaluating	historical	aging	and	write-off	history,	adjusted	for	current	and	forecasted	economic	conditions,	for	groups	of	
receivables	that	share	similar	economic	characteristics.	Other	receivables	are	evaluated	by	reviewing	individual	accounts,	considering	aging,	
financial	condition	of	the	debtor,	recent	payment	history	and	other	relevant	factors.	Account	balances	are	written-off	in	the	period	they	are	
deemed	to	be	uncollectible.

Inventories
Inventories	are	valued	at	the	lower	of	cost	or	net	realizable	value.	Costs	for	fuel,	material	and	supply	inventories	of	our	Electric	segment	are	
determined	on	an	average	cost	basis.	Costs	for	raw	material,	work	in	process	and	finished	goods	inventories	of	our	Manufacturing	and	Plastics	
segments	are	determined	on	a	first-in	first-out	(FIFO)	basis.	

Inventories	consist	of	the	following	as	of	December	31,	2021	and	2020:

Investments
We	invest	in	and	hold,	through	a	rabbi	trust,	corporate-owned	life	insurance	policies	to	provide	future	funding	for	obligations	under	our	
supplemental	pension	plan	and	a	non-qualified	deferred	compensation	plan.	The	polices	are	recorded	at	cash	surrender	value	and	there	are	no	
restrictions	on	our	ability	to	surrender	the	policies.	

We	hold	debt,	mutual	fund	investments	and	money	market	funds	either	as	investments	within	our	captive	insurance	entity	or	to	provide	future	
funding	for	obligations	under	non-qualified	deferred	compensation	plans.	These	investments	are	recorded	at	fair	value.	Debt	securities	are	deemed	
to	be	available-for-sale	securities,	accordingly	unrealized	gains	and	losses	are	generally	excluded	from	earnings	and	recognized	in	accumulated	
other	comprehensive	income.	We	evaluate	whether	declines	in	fair	value	of	debt	securities	below	the	cost	basis	are	other-than-temporary.	
Declines	in	fair	value	deemed	to	be	other-than-temporary	result	in	the	recognition	of	unrealized	losses,	or	a	portion	thereof,	in	earnings.	Unrealized

The	amount	of	unrealized	gains	and	losses	on	debt	securities	as	of	December	31,	2021	and	2020	is	not	material	and	no	unrealized	losses	were	
deemed	to	be	other-than-temporary.	In	addition,	the	amount	of	unrealized	gains	and	losses	on	marketable	equity	securities	still	held	as	of	
December	31,	2021	and	2020	is	not	material.	

Property,	Plant	and	Equipment
Electric	plant	is	stated	at	original	cost.	The	cost	of	additions	includes	contracted	work,	direct	labor	and	materials,	allocable	overheads	and	
allowance	for	funds	used	during	construction.	The	amount	of	interest	capitalized	to	electric	plant	was	$0.6	million	in	2021,	$2.1	million	in	2020	and		
$1.7	million	in	2019.	The	cost	of	depreciable	units	of	property	retired	less	salvage	is	charged	to	accumulated	depreciation.	Amounts	recovered	in	
rates	for	future	removal	costs	are	recorded	as	regulatory	liabilities.	Removal	costs,	when	incurred,	are	charged	against	the	regulatory	liability.	
Maintenance,	repairs	and	replacement	of	minor	items	are	charged	to	operating	expenses	as	incurred.	The	provisions	for	utility	depreciation	for	
financial	reporting	purposes	are	made	on	the	straight-line	method	based	on	the	estimated	remaining	service	lives	of	the	properties.	Gains	or	losses	
on	group	asset	dispositions	are	taken	to	the	accumulated	provision	for	depreciation	reserve	and	impact	current	and	future	depreciation	rates.

Property,	plant	and	equipment	of	nonelectric	operations	are	carried	at	historical	cost	and	are	depreciated	on	a	straight-line	basis	over	the	assets’	
estimated	useful	lives.	The	cost	of	additions	includes	contracted	work,	direct	labor	and	materials,	allocable	overheads	and	capitalized	interest.	No	
interest	was	capitalized	in	2021,	2020	or	2019.	Maintenance	and	repairs	are	expensed	as	incurred.	Gains	or	losses	on	asset	dispositions	are	
included	in	the	determination	of	operating	income.

Jointly	Owned	Facilities
OTP	is	a	joint	owner	in	two	coal-fired	steam-powered	electric	generation	plants:	Big	Stone	Plant	near	Big	Stone	City,	South	Dakota	and	Coyote	
Station	near	Beulah,	North	Dakota.	OTP	is	also	a	joint	owner,	with	other	regional	utilities,	in	five	major	transmission	lines.	OTP's	interest	in	each	
jointly	owned	facility	is	reflected	in	the	consolidated	balance	sheets	on	a	pro-rata	basis	and	OTP's	share	of	direct	revenue	and	expenses	are	
included	in	operating	revenues	and	expenses	in	the	consolidated	statements	of	income.	Each	participant	in	the	jointly	owned	facilities	finances	its	
own	investment.

Goodwill	and	Other	Intangible	Assets
Goodwill	is	recognized	and	initially	measured	as	any	excess	of	the	acquisition-date	consideration	transferred	in	a	business	combination	over	
amounts	recognized	for	the	net	identifiable	assets	acquired.	Goodwill	is	not	amortized	but	is	tested	for	impairment	annually,	or	more	frequently	if	
an	event	occurs	or	circumstances	change	that	would	more	likely	than	not	result	in	an	impairment	of	goodwill.	Impairment	testing	is	performed	at	
the	reporting	unit	level,	which	is	defined	as	an	operating	segment	or	one	level	below	an	operating	segment.	We	perform	our	impairment	testing	in	
the	fourth	quarter	of	each	year	and	have	identified	three	reporting	units	that	carry	a	goodwill	balance.

Our	impairment	testing	includes	both	an	optional	qualitative	assessment	and	the	quantitative	impairment	assessment.	Our	qualitative	assessment	
includes	an	analysis	of	relevant	events	and	circumstances	to	determine	if	it	is	more	likely	than	not	that	the	fair	value	of	the	reporting	unit	exceeds	
its	book	value.	If,	after	this	assessment,	we	determine	that	it	is	not	more	likely	than	not	that	the	fair	value	of	a	reporting	unit	is	less	than	its	carrying	
amount,	no	additional	analysis	is	necessary.	In	contrast,	if	after	the	assessment	we	determine	it	is	more	likely	than	not	that	the	fair	value	of	a	
reporting	unit	is	less	than	its	carrying	amount,	or	if	we	elect	to	skip	the	optional	qualitative	assessment,	the	quantitative	impairment	assessment	is	
performed.	The	quantitative	assessment	is	a	single-step	test	that	identifies	both	the	existence	of	impairment	and	the	amount	of	impairment	loss	by	
comparing	the	estimated	fair	value	of	a	reporting	unit	to	its	carrying	value,	with	any	excess	carrying	value	over	the	fair	value	being	recognized	as	an	
impairment	loss.

Intangible	assets	with	finite	lives,	which	primarily	consist	of	customer	relationships,	are	carried	at	estimated	fair	value	at	the	time	of	acquisition	less	
accumulated	amortization.	The	costs	of	the	intangible	assets	are	amortized	over	their	estimated	useful	lives,	which	generally	range	from	15	to	20	
years.

Leases
We	recognize	right-of-use	lease	assets	and	a	corresponding	lease	liability	at	the	lease	commencement	date.	The	length	of	our	lease	agreements	
varies	from	less	than	one	year	to	approximately	ten	years.	We	have	elected	to	not	record	lease	assets	and	liabilities	for	leases	with	a	lease	term	at	
commencement	of	12	months	or	less;	such	leases	are	expensed	on	a	straight-line	basis	over	the	lease	term.	If	a	lease	contains	an	option	to	extend	
the	lease	term	and	there	is	reasonable	certainty	the	option	will	be	exercised,	the	option	is	considered	in	the	lease	term	at	inception.	We	have	
elected	to	not	separate	non-lease	components	(e.g.,	common	area	maintenance)	from	lease	components	on	real	estate	leases,	accordingly	the	
recognized	lease	asset	and	lease	liability	incorporate	in	their	measurement	payments	for	non-lease	components.	Certain	leases	include	variable	
lease	payments	as	the	amounts	are	subject	to	change	over	the	lease	term.	We	are	unable	to	determine	the	interest	rate	implicit	in	our	leases	thus	
we	apply	our	incremental	borrowing	rate	to	capitalize	the	right-of-use	asset	and	lease	liability.	We	estimate	our	incremental	borrowing	rate	by	
incorporating	considerations	of	lease	term	and	lessee	entity.		

Recoverability	of	Long-Lived	Assets
We	review	our	long-lived	assets	including,	among	other	assets,	property,	plant	and	equipment,	amortizing	intangible	assets	and	right-of-use	lease	
assets,	whenever	events	or	changes	in	circumstances	indicate	the	carrying	amount	of	the	assets	may	not	be	recoverable.	We	determine	potential	
impairment	by	comparing	the	carrying	amount	of	the	assets	with	the	net	cash	flows	expected	to	be	provided	by	operating	activities	of	the	business	
or	related	assets.	If	the	sum	of	the	expected	future	net	cash	flows	is	less	than	the	carrying	amount	of	the	assets,	an	impairment	loss	would	be	
recognized.	Such	an	impairment	loss	would	be	measured	as	the	amount	by	which	the	carrying	amount	exceeds	the	fair	value	of	the	asset.

Asset	Retirement	Obligations
Legal	obligations	related	to	the	future	retirement	of	long-lived	assets	are	recognized	as	asset	retirement	obligations	(ARO).	An	ARO	is	recognized	in	
the	period	in	which	the	legal	obligation	is	incurred	and	the	amount	of	the	obligation	can	be	reasonably	estimated,	with	an	offsetting	increase	to	the	
associated	long-lived	asset.	AROs	are	initially	recognized	at	fair	value	and	increased	with	the	passage	of	time	(accretion),	with	accretion	expense	
recognized	in	the	consolidated	statements	of	income.	ARO	estimates	are	revised	periodically	with	any	adjustment	reflected	in	the	ARO	and	
associated	long-lived	asset.	

Income	Taxes
We	use	the	asset	and	liability	method	to	account	for	income	taxes.	Under	this	method,	deferred	tax	assets	and	liabilities	are	recognized	for	the	
expected	future	tax	consequences	of	all	temporary	differences	between	the	carrying	amounts	of	assets	and	liabilities	and	their	respective	tax	
bases.	Deferred	taxes	are	recorded	using	the	tax	rates	scheduled	by	tax	law	to	be	in	effect	in	the	periods	when	the	temporary	differences	reverse.	
Deferred	tax	assets	are	reduced	by	a	valuation	allowance	when	it	is	more	likely	than	not	that	a	portion	or	all	of	the	deferred	tax	assets	will	not	be	
realized.	The	realizability	of	deferred	tax	assets	takes	into	consideration	forecasts	of	future	taxable	income,	the	reversal	of	other	existing	temporary	
differences,	available	net	operating	loss	carryforwards	and	available	tax	planning	strategies.	Changes	in	valuation	allowances	are	included	in	the	
provision	for	income	taxes	in	the	period	of	the	changes.

We	recognize	the	tax	effects	of	all	tax	positions	that	are	more-likely-than-not	to	be	sustained	on	audit	based	solely	on	the	technical	merits	of	those	
positions	as	of	the	balance	sheet	date.	Changes	in	the	recognition	or	measurement	of	such	positions	are	recognized	in	the	provision	for	income	
taxes	in	the	period	of	the	changes.	We	classify	interest	and	penalties	on	tax	uncertainties	as	components	of	the	provision	for	income	taxes.	

We	amortize	investment	tax	credits	and	state	wind	energy	credits	over	the	estimated	lives	of	the	related	property.

Stock-Based	Compensation
Stock-based	compensation	awards	are	measured	at	the	grant	date	fair	value	of	the	award	and	compensation	expense	is	recognized	on	a	straight-
line	basis	over	the	applicable	service	or	performance	period.	The	service	period	may	be	limited	to	the	period	until	such	time	that	a	recipient	is	
retirement	eligible	as	determined	under	the	award	agreement.	Awards	granted	to	employees	eligible	for	retirement	on	the	date	of	grant	are	
expensed	in	the	period	of	grant.	We	recognize	the	effects	of	award	forfeitures	as	they	occur.

Fair	Value	Measurements
Fair	value	is	defined	as	the	price	that	would	be	received	for	an	asset	or	paid	to	transfer	a	liability	(an	exit	price)	in	the	principal	or	most	
advantageous	market	for	the	asset	or	liability	in	an	orderly	transaction	between	market	participants.	Three	levels	of	inputs	may	be	used	to	measure	
fair	value:

Level	1	–	Quoted	prices	are	available	in	active	markets	for	identical	assets	or	liabilities	as	of	the	reported	date.	The	types	of	assets	and	
liabilities	included	in	Level	1	are	highly	liquid	and	actively	traded	instruments	with	quoted	prices,	such	as	equities	listed	by	the	New	York	Stock	
Exchange	and	commodity	derivative	contracts	listed	on	the	New	York	Mercantile	Exchange.

Level	2	–	Pricing	inputs	are	other	than	quoted	prices	in	active	markets	but	are	either	directly	or	indirectly	observable	as	of	the	reported	date.	

The	types	of	assets	and	liabilities	included	in	Level	2	are	typically	either	comparable	to	actively	traded	securities	or	contracts,	such	as	treasury	
securities	with	pricing	interpolated	from	recent	trades	of	similar	securities,	or	priced	with	models	using	highly	observable	inputs,	such	as	
commodity	options	priced	using	observable	forward	prices	and	volatilities.	

Level	3	–	Significant	inputs	to	pricing	have	little	or	no	observability	as	of	the	reporting	date.	The	types	of	assets	and	liabilities	included	in	Level	

3	are	those	with	inputs	requiring	significant	management	judgment	or	estimation	and	may	include	complex	and	subjective	models	and	forecasts.

48

In	instances	where	the	determination	of	the	fair	value	measurement	is	based	on	inputs	from	different	levels	within	the	hierarchy,	the	level	in	the	
hierarchy	within	which	the	entire	fair	value	measurement	falls	is	based	on	the	lowest	level	input	that	is	significant	to	the	fair	value	measurement	in	
its	entirety.

Variable	Interest	Entity
In	October	2012,	the	Coyote	Station	owners,	including	OTP,	entered	into	a	lignite	sales	agreement	(LSA)	with	Coyote	Creek	Mining	Company,	L.L.C.	
(CCMC),	a	subsidiary	of	The	North	American	Coal	Corporation,	for	the	purchase	of	lignite	coal	to	meet	the	coal	supply	requirements	of	Coyote	
Station	for	the	period	beginning	in	May	2016	and	ending	in	December	2040.	The	price	per	ton	paid	by	the	Coyote	Station	owners	under	the	LSA	
reflects	the	cost	of	production,	along	with	an	agreed	upon	profit	and	capital	charge.	CCMC	was	formed	for	the	purpose	of	mining	coal	to	meet	the	
coal	fuel	supply	requirements	of	Coyote	Station	from	May	2016	through	December	2040	and,	based	on	the	terms	of	the	LSA,	is	considered	a	
variable	interest	entity	(VIE)	due	to	the	transfer	of	all	operating	and	economic	risk	to	the	Coyote	Station	owners,	as	the	agreement	is	structured	so	
that	the	price	of	the	coal	would	cover	all	costs	of	operations	as	well	as	future	reclamation	costs.	The	Coyote	Station	owners	are	required	to	buy	
certain	assets	of	CCMC	at	book	value	should	they	terminate	the	contract	prior	to	the	end	of	the	contract	term	and	are	providing	a	guarantee	of	the	
value	of	the	equity	of	CCMC	because	the	Coyote	Station	owners	are	required	to	buy	the	membership	interests	of	CCMC	at	the	end	of	the	contract	
term	at	equity	value.	Under	current	accounting	standards,	the	primary	beneficiary	of	a	VIE	is	required	to	include	the	assets,	liabilities,	results	of	
operations	and	cash	flows	of	the	VIE	in	its	consolidated	financial	statements.	No	single	owner	of	Coyote	Station	owns	a	majority	interest	in	Coyote	
Station	and	none,	individually,	has	the	power	to	direct	the	activities	that	most	significantly	impact	CCMC.	Therefore,	none	of	the	owners	
individually,	including	OTP,	is	considered	a	primary	beneficiary	of	the	VIE	and	the	Company	is	not	required	to	include	CCMC	in	its	consolidated	
financial	statements.

If	the	LSA	terminates	prior	to	the	expiration	of	its	term	or	the	production	period	terminates	prior	to	December	31,	2040	and	the	Coyote	Station	
owners	purchase	all	of	the	outstanding	membership	interests	of	CCMC,	the	owners	will	satisfy	or,	if	permitted	by	CCMC’s	applicable	lenders,	
assume	all	of	CCMC’s	obligations	owed	to	CCMC’s	lenders	under	its	loans	and	leases.	The	Coyote	Station	owners	have	limited	rights	to	assign	their	
rights	and	obligations	under	the	LSA	without	the	consent	of	CCMC’s	lenders	during	any	period	in	which	CCMC’s	obligations	to	its	lenders	remain	
outstanding.	In	the	event	the	contract	is	terminated	prior	to	the	end	of	the	term	due	to	certain	events,	OTP’s	maximum	exposure	to	additional	
costs,	as	a	result	of	its	involvement	with	CCMC,	and	potential	impairment	loss	if	recovery	of	those	costs	is	denied	by	regulatory	authorities,	could	
be	as	high	as	$45.0	million,	OTP’s	35%	share	of	CCMC’s	unrecovered	costs	as	of	December	31,	2021.

2.	Segment	Information

We	classify	our	business	into	three	segments,	Electric,	Manufacturing	and	Plastics,	consistent	with	our	business	strategy,	organizational	structure	
and	our	internal	reporting	and	review	processes	used	by	our	chief	operating	decision	maker	to	make	decisions	regarding	allocation	of	resources,	to	
assess	operating	performance	and	to	make	strategic	decisions.

Electric	includes	the	production,	transmission,	distribution	and	sale	of	electric	energy	in	Minnesota,	North	Dakota	and	South	Dakota	by	OTP.	In	

addition,	OTP	is	a	participant	in	the	Midcontinent	Independent	System	Operator,	Inc.	(MISO)	markets.	OTP’s	operations	have	been	our	primary	
business	since	1907.

Manufacturing	consists	of	businesses	in	the	following	manufacturing	activities:	contract	machining,	metal	parts	stamping,	fabrication	and	
painting,	and	production	of	plastic	thermoformed	horticultural	containers,	life	science	and	industrial	packaging,	and	material	handling	components.	
These	businesses	have	manufacturing	facilities	in	Georgia,	Illinois	and	Minnesota	and	sell	products	primarily	in	the	United	States.

Plastics	consists	of	businesses	producing	PVC	pipe	at	plants	in	North	Dakota	and	Arizona.	The	PVC	pipe	is	sold	primarily	in	the	western	half	of	

the	United	States	and	Canada.

Certain	assets	and	costs	are	not	allocated	to	our	operating	segments.	Corporate	operating	costs	include	items	such	as	corporate	staff	and	overhead	
costs,	the	results	of	our	captive	insurance	company	and	other	items	excluded	from	the	measurement	of	operating	segment	performance.	
Corporate	assets	consist	primarily	of	cash,	prepaid	expenses,	investments	and	fixed	assets.	Corporate	is	not	an	operating	segment,	rather	it	is	
added	to	operating	segment	totals	to	reconcile	to	consolidated	amounts.

49

Information	for	each	segment	and	our	unallocated	corporate	costs	for	the	years	ended	December	31,	2021,	2020	and	2019	are	as	follows:

Concentrations
Our	Plastics	segment	businesses	use	PVC	resin	as	a	critical	component	within	their	PVC	pipe	manufacturing	process.	There	are	a	limited	number	of	
PVC	resin	suppliers	in	the	U.S.,	and	in	2021,	we	sourced	all	of	our	PVC	resin	needs	from	two	vendors.	Although	there	are	a	limited	number	of	PVC	
resin	suppliers,	we	believe	that	other	suppliers	could	provide	PVC	resin	on	comparable	terms.	Additionally,	most	U.S.	resin	production	plants	are	
located	in	the	Gulf	Coast	region.	These	plants	are	subject	to	the	risk	of	damage	and	production	shutdowns	because	of	exposure	to	hurricanes	or	
other	extreme	weather	events	that	occur	in	this	region.	The	loss	of	a	key	vendor,	or	any	interruption	or	delay	in	the	supply	of	PVC	resin	could	cause	
production	delays,	a	possible	loss	of	sales,	or	result	in	increased	costs	to	secure	resin,	all	of	which	would	adversely	affect	our	operating	results.

Entity-Wide	Information
No	single	customer	accounted	for	over	10%	of	our	consolidated	operating	revenues	for	the	years	ended	December	31,	2021,	2020	and	2019.	All	of	
our	long-lived	assets	are	located	within	the	United	States	and	substantially	all	of	our	operating	revenues	are	to	customers	located	within	the	United	
States.

generation	assets.

Asset	Retirement	Obligations	represent	the	difference	in	timing	of	recognition	of	expense	arising	from	these	obligations	and	the	amount	

recovered	from	customers.

Independent	System	Operator	(ISO)	Cost	Recovery	Trackers	represent	costs	incurred	to	serve	Minnesota	customers	or	the	under-collection	of	

revenue	based	on	expected	versus	actual	construction	costs	on	eligible	projects.

Unrecovered	Project	Costs	reflect	costs	incurred	for	abandoned	generation	and	transmission	assets	and	accelerated	depreciation	expense	on	

a	to-be-retired	generation	asset	expected	to	be	recovered	from	customers.

Deferred	Rate	Case	Expenses	relate	to	costs	incurred	in	conjunction	with	recent	rate	cases	that	are	currently	or	are	expected	to	be	recovered	

from	customers.	

Debt	Reacquisition	Premiums	represent	costs	to	retire	debt	which	are	being	recovered	from	customers	over	the	remaining	original	lives	of	the	

reacquired	debt.

On	September	30,	2021,	OTC	entered	into	a	Fourth	Amended	and	Restated	Credit	Agreement	(the	OTC	Credit	Agreement)	and	OTP	entered	into	a	
Third	Amended	and	Restated	Credit	Agreement	(the	OTP	Credit	Agreement)	amending	and	restating	the	previously	existing	credit	agreements	to	
extend	the	maturity	date	of	each	credit	facility	to	September	30,	2026.	The	agreements	both	provide	for	$170.0	million	unsecured	revolving	lines	of	
credit	to	support	operations,	fund	capital	expenditures,	refinance	certain	indebtedness	and	provide	for	the	issuance	of	letters	of	credit	in	an	
aggregate	amount	not	to	exceed	$40.0	million	under	the	OTC	Credit	Agreement	and	$50.0	million	under	the	OTP	Credit	Agreement.	Each	credit	
facility	includes	an	accordion	provision	allowing	the	borrower,	subject	to	certain	conditions,	to	increase	the	borrowing	capacity	under	the	facility;	
up	to	$290.0	million	under	the	OTC	Credit	Agreement	and	up	to	$250.0	million	under	the	OTP	Credit	Agreement.		

Borrowings	under	each	credit	facility	are	subject	to	a	variable	rate	of	interest	on	outstanding	balances	and	a	commitment	fee	is	charged	based	on	
the	average	unused	amount	available	to	be	drawn	under	the	respective	facility.	The	variable	rate	of	interest	to	be	charged	is	based	on	a	benchmark	
interest	rate,	either	LIBOR	or	a	Base	Rate,	as	defined	in	the	credit	agreements,	selected	by	the	borrower	at	the	time	of	an	advance,	subject	to	the	
conditions	of	each	agreement,	plus	an	applicable	credit	spread.	The	credit	spread	ranges	from	zero	to	2.00%,	depending	on	the	benchmark	interest	
rate	selected	and	is	subject	to	adjustment	based	on	the	credit	ratings	of	the	relevant	borrowers.	The	weighted-average	interest	rate	on	all	
outstanding	borrowings	as	of	December	31,	2021	and	2020	was	1.42%	and	1.61%.

Each	credit	facility	contains	a	number	of	restrictions	on	the	borrower,	including	restrictions	on	the	ability	to	merge,	sell	assets,	make	investments,	
create	or	incur	liens	on	assets,	guarantee	the	obligations	of	any	other	party	and	engage	in	transactions	with	related	parties.	The	agreements	also	
contain	certain	financial	and	non-financial	covenants	and	defined	events	of	default.

Both	the	OTC	Credit	Agreement	and	the	OTP	Credit	Agreement	include	interest	rates	determined	by	a	reference	to	LIBOR.	The	applicable	LIBOR	
tenors	are	currently	scheduled	to	be	eliminated	on	June	30,	2023.	In	the	event	that	LIBOR	is	no	longer	available,	both	credit	agreements	contain	
provisions	for	the	replacement	of	LIBOR	as	the	benchmark	rate	with	the	Secured	Overnight	Finance	Rate	(SOFR).	The	transition	to	SOFR	may	be	
triggered	by	the	discontinuation	or	loss	of	representativeness	of	the	applicable	LIBOR	tenors	or	as	earlier	elected	by	the	borrowers,	subject	to	
approval	by	the	lender.

On	June	10,	2021,	OTP	entered	into	a	Note	Purchase	Agreement	pursuant	to	which	OTP	agreed	to	issue,	in	a	private	placement	transaction,	
$230.0	million	of	senior	unsecured	notes	consisting	of	(a)	$40.0	million	of	2.74%	Series	2021A	Senior	Unsecured	Notes	due	November	29,	2031,	(b)	
$100.0	million	of	3.69%	Series	2021B	Senior	Unsecured	Notes	due	November	29,	2051	and	(c)	$90.0	million	of	3.77%	Series	2022A	Senior	
Unsecured	Notes	due	May	20,	2052.	During	the	year	ended	December	31,	2021,	OTP	issued	its	Series	2021A	and	Series	2021B	notes	for	aggregate	
proceeds	of	$140.0	million,	which	were	used	to	repay	the	Series	2011A	notes.	The	issuance	of	the	Series	2022A	notes	is	scheduled	to	close,	subject	
to	the	satisfaction	of	certain	customary	conditions	to	closing,	in	May	2022.

Our	guaranteed	and	unsecured	notes	require	the	borrower	to	maintain	various	financial	covenants,	as	further	described	below.	These	notes	
provide	for	prepayment	options	allowing	for	a	full	or	partial	prepayment	at	100%	of	the	principal	amount	so	prepaid,	together	with	unpaid	accrued	
interest	and	a	make-whole	amount,	as	defined.	These	notes	also	include	restrictions	on	the	borrowers,	including	its	ability	to	merge,	sell	assets,	
create	or	incur	liens	on	assets,	guarantee	the	obligations	of	any	other	party	and	engage	in	transactions	with	related	parties.

Aggregate	maturities	of	long-term	debt	obligations	at	December	31,	2021	for	each	of	the	next	five	years	are	as	follows:

Financial	Covenants
Certain	of	OTC's	and	OTP's	short-term	and	long-term	debt	agreements	require	the	borrower,	whether	OTC	or	OTP,	to	maintain	certain	financial	
covenants,	including	a	maximum	debt	to	total	capitalization	of	0.60	to	1.00,	a	minimum	interest	and	dividend	coverage	ratio	of	1.50	to	1.00,	and	a	
maximum	level	of	priority	indebtedness.		As	of	December	31,	2021,	OTC	and	OTP	were	in	compliance	with	these	financial	covenants.

10.	Employee	Postretirement	Benefits

Pension	Plan	and	Other	Postretirement	Benefits
The	Company	sponsors	a	noncontributory	funded	pension	plan	(the	"Pension	Plan"),	an	unfunded,	nonqualified	Executive	Survivor	and	
Supplemental	Retirement	Plan	("ESSRP"),	both	accounted	for	as	defined	benefit	pension	plans,	and	a	postretirement	healthcare	plan	accounted	for	
as	an	other	postretirement	benefit	plan.

The	Pension	Plan,	which	previously	covered	substantially	all	corporate	and	OTP	employees,	was	closed	to	new	employees	in	2013.	The	plan	
provides	retirement	compensation	to	all	covered	employees	at	age	65,	with	reduced	compensation	in	cases	of	retirement	prior	to	age	62.

Participants	are	fully	vested	after	completing	five	years	of	vesting	service.	The	plan	assets	consist	of	equity	funds,	fixed	income	funds,	cash	and	cash	
equivalents	and	alternative	investments.	None	of	the	plan	assets	are	invested	in	common	stock	or	debt	securities	of	the	Company.

The	ESSRP,	an	unfunded	plan,	provides	for	defined	benefit	payments	to	executive	officers	and	certain	key	management	employees	on	their	
retirement	for	life,	or	to	their	beneficiaries	on	their	death.	The	ESSRP	was	amended	and	restated	in	2019	to	i)	freeze	the	participation	in	the	
restoration	retirement	benefit	component	of	the	plan	and	ii)	freeze	benefit	accruals	under	the	restoration	retirement	benefit	component	of	the	
plan	for	all	participants	of	the	plan,	except	any	participants	deemed	to	be	grandfathered	participants.	

The	postretirement	healthcare	plan,	closed	to	new	participants	in	2010,	provides	a	portion	of	health	insurance	benefits	for	retired	and	covered	
corporate	and	OTP	employees.	To	be	eligible	for	retiree	health	insurance	benefits,	the	employee	must	be	55	years	of	age	with	a	minimum	of	10	
years	of	service.	The	plan	is	an	unfunded	plan	and	accordingly	holds	no	plan	assets.

Pension	Plan	Assets.	We	have	established	a	Retirement	Plans	Administration	Committee	to	develop	and	monitor	our	investment	strategy	for	

our	Pension	Plan	assets.	Our	investment	strategy	includes	the	following	objectives:

• The	assets	of	the	plan	will	be	invested	in	accordance	with	all	applicable	laws	in	a	manner	consistent	with	fiduciary	standards	including

Employee	Retirement	Income	Security	Act	standards	of	1974	(ERISA)	(if	applicable).	Specifically:

◦ The	safeguards	and	diversity	that	a	prudent	investor	would	adhere	to	must	be	present	in	the	investment	program.
◦ All	transactions	undertaken	on	behalf	of	the	Pension	Plan	must	be	in	the	best	interest	of	plan	participants	and	their	beneficiaries.

• The	primary	objective	is	to	provide	a	source	of	retirement	income	for	its	participants	and	beneficiaries.

• The	near-term	primary	financial	objective	is	to	improve	and	protect	the	funded	status	of	the	plan.

• A	secondary	financial	objective	is	to	minimize	pension	funding	and	expense	volatility	where	possible.

We	have	developed	an	asset	allocation	target,	measured	at	investment	market	value,	to	provide	guideline	percentages	of	investment	mix.	This	
investment	mix	is	intended	to	achieve	the	financial	objectives	of	the	plan.	The	permitted	range	is	a	guide	and	will	at	times	not	reflect	the	actual	
asset	allocation	due	to	market	conditions,	actions	of	our	investment	managers	and	required	cash	flows	to	and	from	the	Pension	Plan.	

The	following	table	presents	our	target	asset	allocation	permitted	range	along	with	the	actual	asset	allocation	as	of	December	31,	2021	and	2020:

Return	Enhancement	investments	are	those	that	seek	to	provide	equity-like,	long-term	capital	appreciation.	Examples	include	equity	

securities,	including	dynamic	asset	allocation	funds,	and	higher	yielding	fixed	income	securities,	such	as	high	yield	bonds	and	emerging	market	debt.

Risk	Management	investments	seek	to	decrease	downside	risk	or	act	as	a	hedge	against	plan	liabilities.	Examples	are	cash	and	fixed	income	

instruments.

Alternative	investments	seek	to	either	provide	return	enhancement	through	long-term	appreciation	or	risk	management	through	decreased	
downside	risk.	The	defining	characteristic	of	these	asset	types	is	uncorrelated	source	of	returns,	less	liquidity	and	private	market	access.	Examples	
include	investments	in	the	SEI	Energy	Debt	Collective	Fund.

The	investments	held	by	the	SEI	Energy	Debt	Collective	Fund	on	December	31,	2021	and	2020	consist	mainly	of	below	investment	grade	high	yield	
bonds	and	loans	of	U.S.	energy	companies	which	trade	at	a	discount	to	fair	value.	Redemptions	are	allowed	semi-annually	with	a	95-day	notice	
period,	subject	to	fund	director	consent	and	certain	gate,	holdback	and	suspension	restrictions.	Subscriptions	are	allowed	monthly	with	a	three-
year	lock	up	on	subscriptions.	The	fund’s	assets	are	valued	in	accordance	with	valuations	reported	by	the	fund’s	sub-advisor	or	the	fund’s	
underlying	investments	or	other	independent	third-party	sources,	although	SEI	in	its	discretion	may	use	other	valuation	methods,	subject	to	
compliance	with	ERISA,	as	applicable.	On	an	annual	basis,	as	determined	by	the	investment	manager	in	its	sole	discretion,	an	independent	valuation	
agent	is	retained	to	provide	a	valuation	of	the	illiquid	assets	of	the	fund	and	of	any	other	asset	of	the	fund.

The	pension	benefit	liability	of	our	Pension	Plan	decreased	$38.2	million	from	December	31,	2020	to	December	31,	2021	primarily	due	to	an	
increase	in	the	discount	rate	used	to	measure	the	obligation,	from	2.78%	to	3.03%,	respectively,	and	from	actual	returns	on	Pension	Plan	
investments	in	2021	exceeding	the	expected	return	for	the	year.

recognized	in	the	consolidated	statements	of	income,	service	cost	is	recognized	within	one	of	the	components	of	operating	expenses.	Nonservice

We	develop	our	estimated	discount	rate	through	the	use	of	a	hypothetical	bond	portfolio	method.	This	method	derives	the	discount	rate	from	the	
average	yield	of	a	collection	of	high	credit	quality	bonds	which	produce	cash	flows	similar	to	our	anticipated	future	benefit	payments.	We	estimate	
the	assumed	long-term	rate	of	return	on	plan	assets	based	primarily	on	asset	category	studies	using	historical	market	return	and	volatility	data	with

Contingencies

FERC	ROE.	In	November	2013	and	February	2015,	customers	filed	complaints	with	the	FERC	seeking	to	reduce	the	ROE	component	of	the	
transmission	rates	that	MISO	transmission	owners,	including	OTP,	may	collect	under	the	MISO	tariff	rate.	The	FERC's	most	recent	order,	issued	on	
November	19,	2020,	adopted	a	revised	ROE	methodology	and	set	the	base	ROE	at	10.02%	(10.52%	with	an	adder)	effective	for	the	fifteen-month	
period	from	November	2013	to	February	2015	and	on	a	prospective	basis	beginning	in	September	2016.	The	order	also	dismissed	any	complaints	
covering	the	period	from	February	2015	to	May	2016.	The	November	2020	opinion	is	subject	to	judicial	review.	We	have	deferred	recognition	and	
recorded	a	refund	liability	of	$2.5	million	as	of	December	31,	2021.	This	refund	liability	reflects	our	best	estimate	of	required	refunds	to	customers	
once	all	regulatory	and	judicial	proceedings	are	finalized.			

Regional	Haze	Rule	(RHR).	The	RHR	was	adopted	in	an	effort	to	improve	visibility	in	national	parks	and	wilderness	areas.	The	RHR	requires	
states,	in	coordination	with	the	EPA	and	other	governmental	agencies,	to	develop	and	implement	plans	to	achieve	natural	visibility	conditions.	The	
second	RHR	implementation	period	covers	the	years	2018-2028.	States	are	required	to	submit	a	state	implementation	plan	to	assess	reasonable	
progress	with	the	RHR	and	determine	what	additional	emission	reductions	are	appropriate,	if	any.

Coyote	Station,	OTP's	jointly	owned	coal-fired	power	plant	in	North	Dakota,	is	subject	to	assessment	in	the	second	implementation	period	under	
the	North	Dakota	state	implementation	plan.	In	September	2021,	the	North	Dakota	Department	of	Environmental	Quality	(NDDEQ)	made	public	a	
draft	of	its	state	implementation	plan.	The	plan	concluded	it	is	not	reasonable	to	require	additional	emission	controls	during	this	planning	period.	
Following	a	consultation	and	public	comment	period,	and	any	subsequent	modifications	to	the	plan,	the	NDDEQ	will	submit	its	state	
implementation	plan	to	the	EPA	for	approval.	In	January	2022,	prior	to	the	submission	to	the	EPA	by	the	NDDEQ,	the	EPA	provided	preliminary	
comments	on	the	draft	North	Dakota	state	implementation	plan	in	which	it	expressed	disagreement	with	the	NDDEQ's	recommendation	to	forgo	
additional	emission	controls.				

We	cannot	predict	with	certainty	the	impact	the	state	implementation	plan	may	have	on	our	business	until	the	state	implementation	plan	has	been	
approved	or	otherwise	fully	acted	on	by	the	EPA.	However,	significant	emission	control	investments	could	be	required	and	the	recovery	of	such	
costs	from	customers	would	require	regulatory	approval.	Alternatively,	investments	in	emission	control	equipment	may	prove	to	be	uneconomic	
and	result	in	the	early	retirement	of,	or	the	sale	of	our	interest	in,	Coyote	Station,	subject	to	regulatory	approval.	We	cannot	estimate	the	financial	
effects	such	a	retirement	or	sale	may	have	on	our	consolidated	operating	results,	financial	position	or	cash	flows,	but	such	amounts	could	be	
material	and	the	recovery	of	such	costs	from	customers	would	be	subject	to	regulatory	approval.

Westmoreland	Coal	Company	(Westmoreland)	Arbitration.	In	December	2018,	insurers	for	Westmoreland,	Westmoreland	and	its	affiliated	

companies	filed	an	arbitration	demand	against	the	co-owners	of	Coyote	Station,	including	OTP,	a	35%	co-owner.	The	claimant	insurers	were	
pursuing	recovery	in	the	amount	of	$5.5	million,	plus	prejudgment	interest	to	recover	business	interruption	insurance	proceeds	paid	to	
Westmoreland	or	its	affiliates	arising	from	a	boiler	feed	pump	explosion	in	December	2014	at	the	facility.	The	explosion	and	ensuing	repairs	
reduced	the	amount	of	coal	purchased	from	a	Westmoreland	affiliate	under	an	existing	coal	purchase	agreement.	The	Westmoreland	insurers	
claimed	the	co-owners	breached	the	minimum	purchase	obligations	in	the	coal	purchase	agreement.	As	of	December	31,	2021,	an	agreement	to	
settle	the	matter	was	reached,	and	OTP's	proportionate	share	of	the	settlement	payment	did	not	have	a	material	effect	on	its	2021	financial	results.

Other	Contingencies.	We	are	party	to	litigation	and	regulatory	enforcement	matters	arising	in	the	normal	course	of	business.	We	regularly	

analyze	relevant	information	and,	as	necessary,	estimate	and	record	accrued	liabilities	for	matters	in	which	a	loss	is	probable	of	occurring	and	can	
be	reasonably	estimated.	We	believe	the	effect	on	our	consolidated	operating	results,	financial	position	and	cash	flows,	if	any,	for	the	disposition	of	
all	matters	pending	as	of	December	31,	2021,	other	than	those	relating	to	the	RHR,	will	not	be	material.

14.	Stockholders'	Equity

Capital	Structure
In	addition	to	authorized	and	outstanding	common	stock,	the	Company	has	1,500,000	authorized	no	par	value	cumulative	preferred	shares	and	
1,000,000	authorized	no	par	value	cumulative	preference	shares.	No	cumulative	preferred	or	cumulative	preference	shares	were	outstanding	at	
December	31,	2021	or	2020.

Shelf	Registrations
On	May	3,	2021,	upon	the	expiration	of	a	prior	shelf	registration,	we	filed	a	shelf	registration	statement	with	the	SEC	under	which	we	may	offer	for	
sale,	from	time	to	time,	either	separately	or	together	in	any	combination,	equity,	debt	or	other	securities	described	in	the	shelf	registration	
statement.	The	registration	statement	expires	in	May	2024.	No	shares	were	issued	pursuant	to	the	shelf	registration	in	2021.

On	May	3,	2021,	upon	the	expiration	of	a	second	prior	shelf	registration,	we	filed	a	second	registration	statement	with	the	SEC	for	the	issuance	of	
up	to	1,500,000	common	shares	under	an	Automatic	Dividend	Reinvestment	and	Share	Purchase	Plan,	which	provides	shareholders,	retail	
customers	of	OTP	and	other	interested	investors	a	method	of	purchasing	our	common	shares	by	reinvesting	their	dividends	and/or	making	optional	
cash	investments.	Shares	purchased	under	the	plan	may	be	new	issue	common	shares	or	common	shares	purchased	on	the	open	market.	In	2021,	
we	issued	115,180	shares	under	this	program	and	no	proceeds	were	received,	as	all	shares	issued	were	purchased	on	the	open	market.	As	of	
December	31,	2021,	1,384,820	shares	remain	available	for	purchase	or	issuance	under	the	Plan.	The	shelf	registration	for	the	plan	expires	in	May	
2024.

Dividend	Restrictions
OTC	is	a	holding	company	with	no	significant	operations	of	its	own.	The	primary	source	of	funds	for	payments	of	dividends	to	our	shareholders	is	
from	dividends	paid	or	distributions	made	by	our	subsidiaries.	As	a	result	of	certain	statutory	limitations	or	regulatory	or	financing	agreements,	
restrictions	could	occur	on	the	amount	of	distributions	allowed	to	be	made	by	our	subsidiaries.	Both	the	OTC	Credit	Agreement	and	OTP	Credit	

64

Agreement	contain	restrictions	on	the	payment	of	cash	dividends	upon	a	default	or	event	of	default,	including	failure	to	maintain	certain	financial	
covenants.	As	of	December	31,	2021,	we	were	in	compliance	with	these	financial	covenants.

Under	the	Federal	Power	Act,	a	public	utility	may	not	pay	dividends	from	any	funds	properly	included	in	a	capital	account.	What	constitutes	“funds	
properly	included	in	a	capital	account”	is	undefined	in	the	Federal	Power	Act	and	the	related	regulations;	however,	the	FERC	has	consistently	
interpreted	the	provision	to	allow	dividends	to	be	paid	as	long	as	i)	the	source	of	the	dividends	is	clearly	disclosed,	ii)	the	dividend	is	not	excessive	
and	iii)	there	is	no	self-dealing	on	the	part	of	corporate	officials.

The	MPUC	indirectly	limits	the	amount	of	dividends	OTP	can	pay	to	the	Company	by	requiring	an	equity-to-total-capitalization	ratio	between	47.5%	
and	58.1%	based	on	OTP’s	capital	structure	requirements	as	of	December	31,	2021.	As	of	December	31,	2021,	OTP’s	equity-to-total-capitalization	
ratio	including	short-term	debt	was	52.5%	and	its	net	assets	restricted	from	distribution	totaled	approximately	$681.2	million.	Under	the	current	
capital	structure	requirement	as	of	December	31,	2021,	total	capitalization	for	OTP	could	not	exceed	$1.7	billion.	The	MPUC	approved	OTP’s	most	
recent	capital	structure	petition	on	January	26,	2022,	allowing	for	an	equity-to-total-capitalization	ratio	between	48.0%	and	58.7%,	with	total	
capitalization	not	to	exceed	$1.7	billion.

15.	Accumulated	Other	Comprehensive	Income	(Loss)

The	Company's	other	comprehensive	income	consists	of	unamortized	actuarial	losses	and	prior	service	costs	related	to	pension	and	other	
postretirement	benefits	and	unrealized	gains	and	losses	on	marketable	securities	classified	as	available-for-sale.	The	income	tax	expense	or	benefit	
associated	with	amounts	reclassified	from	accumulated	other	comprehensive	income	(loss)	and	reflected	in	the	consolidated	statement	of	income	
are	recognized	in	the	same	period	as	the	amounts	are	reclassified.

16.	Share-Based	Payments

Employee	Stock	Purchase	Plan
The	1999	Employee	Stock	Purchase	Plan	authorizes	the	issuance	of	1,400,000	common	shares,	allowing	eligible	employees	to	purchase	our	
common	shares	through	payroll	withholding	at	a	discount	of	up	to	15%	off	the	market	price	at	the	end	of	each	six-month	purchase	period.	
Employee	withholding	amounts	may	not	be	less	than	$10	or	more	than	$2,000	per	month,	subject	to	certain	limitations,	as	described	in	the	plan.	A	
plan	participant	may	cease	making	payroll	deductions	at	any	time.	A	participant	may	not	purchase	more	than	2,000	shares	in	a	given	six	month	
purchase	period	under	the	plan	and	may	not	purchase	more	than	$25,000	(fair	market	value)	of	common	shares	under	the	plan	and	all	other	
purchase	plans	(if	any)	in	a	calendar	year.	A	participant	may	withdraw	from	the	plan	at	any	time	and	elect	to	receive	the	balance	of	their	
contributions	to	the	plan	that	have	not	yet	been	used	to	purchase	shares	in	cash.	Shares	purchased	under	the	plan	are	automatically	enrolled	in	the	
Company's	dividend	reinvestment	plan.	Shares	purchased	under	the	plan	may	not	be	assigned,	transferred,	pledged,	or	otherwise	disposed,	except	
for	certain	situations	allowed	by	the	plan,	such	as	upon	death,	for	a	period	of	18	months	after	purchase.	For	purchase	periods	between	January	1,	
2018	and	June	30,	2019,	the	purchase	price	was	100%	of	the	market	price	at	the	end	of	each	six-month	purchase	period.	For	purchase	periods	
beginning	after	June	30,	2019,	the	purchase	price	is	85%	of	the	market	price	at	the	end	of	each	six-month	purchase	period.	At	our	discretion,	shares	
purchased	under	the	plan	can	be	either	new	issue	shares	or	shares	purchased	in	the	open	market.	The	plan	shall	automatically	terminate	when	all	
of	the	shares	authorized	under	the	plan	have	been	issued.

We	recognize	the	15%	discount	to	the	fair	market	value	of	the	purchased	shares	as	stock-based	compensation	expense,	which	amounted	to	$0.2	
million,	$0.2	million	and	$0.1	million	for	the	years	ended	December	31,	2021,	2020,	and	2019.	For	the	years	ended	December	31,	2021,	2020,	and	
2019	the	amount	of	shares	issued	under	the	plan	amounted	to	27,975,	31,661	and	17,104	shares.	As	of	December	31,	2021,	there	was	290,127	
shares	available	for	purchase	under	the	plan.	

Share-Based	Compensation	Plan
The	2014	Stock	Incentive	Plan,	which	was	approved	by	our	shareholders	in	April	2014,	authorizes	the	issuance	of	1,900,000	common	shares	for	the	
granting	of	stock	options,	stock	appreciation	rights,	restricted	stock,	restricted	stock	units,	performance	awards	and	other	stock	and	stock-based	
awards.	As	of	December	31,	2021,	722,200	shares	were	available	for	issuance	under	the	plan.	The	plan	terminates	on	December	31,	2023.

We	grant	restricted	stock	awards	to	our	employees	and	members	of	our	Board	of	Directors	and	stock	performance	awards	to	our	executive	officers	
and	certain	other	key	employees	as	part	of	our	long-term	compensation	and	retention	program.	Stock-based	compensation	cost,	recognized	within	
operating	expenses	in	the	consolidated	statements	of	income,	amounted	to	$6.7	million,	$6.1	million	and	$5.9	million	for	the	years	ended	
December	31,	2021,	2020	and	2019.	The	related	income	tax	benefit	recognized	for	these	periods	amounted	to	$1.8	million,	$2.1	million	and	$2.3	
million.	

Restricted	Stock	Awards.	Restricted	stock	awards	are	granted	to	employees	and	members	of	the	Company's	Board	of	Directors.	The	awards	

vest,	depending	on	award	recipient,	either	ratably	over	a	period	of	three	to	four	years	or	cliff	vest	after	four	years.	Vesting	is	accelerated	in	certain	
circumstances,	including	upon	retirement.	Awards	granted	to	members	of	the	Board	of	Directors	are	issued	and	outstanding	upon	grant	and	carry	
the	same	voting	and	dividend	rights	of	unrestricted	outstanding	common	stock.	Awards	granted	to	executive	officers	and	other	key	employees	are	
eligible	to	receive	dividend	equivalent	payments	during	the	vesting	period,	subject	to	forfeiture	under	the	terms	of	the	agreement,	but	such	awards	
are	not	issued	or	outstanding	upon	grant	and	do	not	provide	for	voting	rights.

The	grant	date	fair	value	of	each	restricted	stock	award	is	determined	based	on	the	market	price	of	the	Company's	common	stock	on	the	date	of	
grant	adjusted	to	exclude	the	value	of	dividends	for	those	awards	that	do	not	receive	dividend	or	dividend	equivalent	payments	during	the	vesting	
period.

The	following	is	a	summary	of	restricted	stock	award	activity	for	the	year	ended	December	31,	2021:

2019.	The	fair	value	of	vested	awards	was	$2.1	million,	$2.8	million	and	$2.4	million	during	the	years	ended	December	31,	2021,	2020	and	2019.	As	
of	December	31,	2021,	there	was	$2.4	million	of	unrecognized	compensation	costs	for	non-vested	restricted	stock	awards	to	be	recognized	over	a	
weighted-average	period	of	1.83	years.

Stock	Performance	Awards.	Stock	performance	awards	are	granted	to	executive	officers	and	certain	other	key	employees.	The	awards	vest	at	

the	end	of	a	three-year	performance	period.	The	number	of	common	shares	awarded,	if	any,	at	the	end	of	the	performance	period	ranges	from	
zero	to	150%	of	the	target	amount	based	on	two	performance	measures:	i)	total	shareholder	return	relative	to	a	peer	group	and	ii)	return	on	
equity.	The	awards	have	no	voting	or	dividend	rights	during	the	vesting	period.	Vesting	of	the	awards	is	accelerated	in	certain	circumstances,	
including	upon	retirement.	The	amount	of	common	shares	awarded	on	an	accelerated	vesting	is	based	either	on	actual	performance	at	the	end	of	
the	performance	period	or	the	amount	of	common	shares	earned	at	target.

The	grant	date	fair	value	of	stock	performance	awards	granted	during	the	years	ended	December	31,	2021,	2020	and	2019	was	determined	using	a

The	risk-free	interest	rate	was	derived	from	yields	on	U.S.	government	bonds	of	a	similar	term.	The	expected	term	of	the	award	is	equal	to	the	
three-year	performance	period.	Expected	volatility	was	estimated	based	on	actual	historical	volatility	of	our	common	stock	over	a	three-	or	five-
year	period.	Dividend	yield	was	estimated	based	on	historic	and	future	yield	estimates.

a	weighted-average	period	of	1.19	years.

17.	Earnings	Per	Share

The	numerator	used	in	the	calculation	of	both	basic	and	diluted	earnings	per	share	is	net	income.	The	denominator	used	in	the	calculation	of	basic	
earnings	per	share	is	the	weighted	average	number	of	shares	outstanding	during	the	period.	The	denominator	used	in	the	calculation	of	diluted	
earnings	per	share	is	derived	by	adjusting	basic	shares	outstanding	for	the	dilutive	effect	of	potential	shares	outstanding,	which	consist	of	time	and	
performance	based	stock	awards	and	employee	stock	purchase	plan	shares.

The	following	includes	the	computation	of	the	denominator	for	basic	and	diluted	weighted-average	shares	outstanding	for	the	years	ended

18.	Derivative	Instruments

OTP	enters	into	derivative	instruments	to	manage	its	exposure	to	future	commodity	price	variability	and	reduce	volatility	in	prices	for	our	retail	
electric	customers.	These	derivative	instruments	are	not	designated	as	qualifying	hedging	transactions	but	provide	for	an	economic	hedge	against	
future	price	variability.	The	instruments	are	recorded	at	fair	value	on	the	consolidated	balance	sheets,	with	changes	in	fair	value	recorded	in	the	
consolidated	statements	of	income.	However,	in	accordance	with	rate-making	and	cost	recovery	processes,	we	recognize	a	regulatory	asset	or	
liability	to	defer	losses	or	gains	from	derivative	activity	until	settlement	of	the	associated	derivative	instrument.	

As	of	December	31,	2021,	OTP	had	outstanding	pay-fixed,	receive-variable	swap	agreements	with	an	aggregate	notional	amount	of	263,400	
megawatt-hours	of	electricity,	and	various	settlement	dates	throughout	2022.	As	of	December	31,	2021,	the	aggregate	fair	value	of	these	contracts	
was	$6.2	million,	which	is	included	in	other	current	assets	on	the	consolidated	balance	sheets.	During	the	year	ended	December	31,	2021,	contracts	
matured	and	were	settled	in	an	aggregate	amount	of	$3.1	million.

The	level	2	fair	value	measurements	for	government-backed	and	government-sponsored	enterprises’	and	corporate	debt	securities	are	determined	
on	the	basis	of	valuations	provided	by	a	third-party	pricing	service	which	utilizes	industry	accepted	valuation	models	and	observable	market	inputs	
to	determine	valuation.	Some	valuations	or	model	inputs	used	by	the	pricing	service	may	be	based	on	broker	quotes.

The	level	2	fair	value	measurements	for	derivative	instruments	are	determined	by	using	inputs	such	as	forward	electric	commodity	prices,	adjusted	
for	location	differences.	These	inputs	are	observable	in	the	marketplace	throughout	the	full	term	of	the	instrument,	can	be	derived	from	
observable	data,	or	are	supported	by	observable	levels	at	which	transactions	are	executed	in	the	marketplace.	

In	addition	to	assets	recorded	at	fair	value	on	a	recurring	basis,	we	also	hold	financial	instruments	that	are	not	recorded	at	fair	value	in	the	
consolidated	balance	sheets	but	for	which	disclosure	of	the	fair	value	of	these	financial	instruments	is	provided.	The	following	reflects	the	carrying	
value	and	estimated	fair	value	of	these	assets	and	liabilities	as	of	December	31,	2021	and	2020:

The	following	methods	and	assumptions	were	used	to	estimate	the	fair	value	of	each	class	of	financial	instruments:

Cash	Equivalents:	The	carrying	amount	approximates	fair	value	because	of	the	short-term	maturity	of	these	instruments.

Short-Term	Debt:	The	carrying	amount	approximates	fair	value	because	the	debt	obligations	are	short-term	in	nature	and	balances	

outstanding	are	subject	to	variable	rates	of	interest	which	reset	frequently,	a	Level	2	fair	value	input.

Long-Term	Debt:	The	fair	value	of	long-term	debt	is	estimated	based	on	current	market	indications	for	borrowings	of	similar	maturities	with	

similar	terms,	a	Level	2	fair	value	input.

Evaluation	of	Disclosures	Controls	and	Procedures.	Under	the	supervision	and	with	the	participation	of	the	Company’s	management,	including	the	
Chief	Executive	Officer	and	the	Chief	Financial	Officer,	the	Company	evaluated	the	effectiveness	of	the	design	and	operation	of	its	disclosure	
controls	and	procedures	(as	defined	in	Rule	13a-15(e)	under	the	Securities	Exchange	Act	of	1934	(the	Exchange	Act))	as	of	December	31,	2021,	the	
end	of	the	period	covered	by	this	report.	Based	on	that	evaluation,	the	Chief	Executive	Officer	and	Chief	Financial	Officer	concluded	that	the	
Company’s	disclosure	controls	and	procedures	were	effective	as	of	December	31,	2021.

Changes	in	Internal	Control	over	Financial	Reporting.	There	were	no	changes	in	the	Company’s	internal	control	over	financial	reporting	(as	defined	
in	Rules	13a-15(f)	under	the	Exchange	Act)	during	the	fourth	quarter	ended	December	31,	2021	that	have	materially	affected,	or	are	reasonably	
likely	to	materially	affect,	the	Company’s	internal	control	over	financial	reporting.

Management’s	Report	Regarding	Internal	Control	Over	Financial	Reporting.	Management	is	responsible	for	the	preparation	and	integrity	of	the	
consolidated	financial	statements	and	representations	in	this	report	on	Form	10-K.	The	consolidated	financial	statements	of	the	Company	have	
been	prepared	in	conformity	with	generally	accepted	accounting	principles	applied	on	a	consistent	basis	and	include	some	amounts	that	are	based	
on	informed	judgments	and	best	estimates	and	assumptions	of	management.

In	order	to	assure	the	consolidated	financial	statements	are	prepared	in	conformance	with	generally	accepted	accounting	principles,	management	
is	responsible	for	establishing	and	maintaining	adequate	internal	control	over	financial	reporting,	as	such	term	is	defined	in	Exchange	Act	Rule	
13a-15(f).	These	internal	controls	are	designed	only	to	provide	reasonable	assurance,	on	a	cost-effective	basis,	that	transactions	are	carried	out	in	
accordance	with	management’s	authorizations	and	assets	are	safeguarded	against	loss	from	unauthorized	use	or	disposition.

Management	has	completed	its	assessment	of	the	effectiveness	of	the	Company’s	internal	control	over	financial	reporting	as	of	December	31,	
2021.	In	making	this	assessment,	management	used	the	criteria	set	forth	by	the	Committee	of	Sponsoring	Organizations	of	the	Treadway	
Commission	in	Internal	Control	-	Integrated	Framework	(2013)	to	conduct	the	required	assessment	of	the	effectiveness	of	the	Company’s	internal	
control	over	financial	reporting.	Based	on	this	assessment,	management	concluded	that,	as	of	December	31,	2021,	the	Company’s	internal	control	
over	financial	reporting	was	effective	based	on	those	criteria.	The	Company’s	independent	registered	public	accounting	firm,	Deloitte	&	Touche	
LLP,	has	audited	the	Company’s	consolidated	financial	statements	included	in	this	report	on	Form	10-K	and	issued	an	attestation	report	on	the	
Company’s	internal	control	over	financial	reporting.

Attestation	Report	of	Independent	Registered	Public	Accounting	Firm.	The	attestation	report	of	Deloitte	&	Touche	LLP,	the	Company’s

		SHAREHOLDER	SERVICES	
OTTER	TAIL	CORPORATION	STOCK	LISTING
Otter	Tail	Corporation	common	stock	trades	on	the	Nasdaq	Global	Select	Market.	Our	ticker	symbol	is	OTTR.	You	can	find	our	daily	stock	price	on	
our	website,	www.ottertail.com.	Shareholders	who	sign	up	for	Internet	account	access	can	view	their	account	information	online.

DIVIDENDS
Otter	Tail	Corporation	has	paid	dividends	on	our	common	shares	each	quarter	since	1938	without	interruption	or	reduction.	2021	dividends	were	
$1.56	per	share,	and	the	year-end	yield	was	2.2	percent.	Total	shareholder	return	grew	at	a	compounded	average	annual	rate	of	16.7	percent	for	
the	past	ten	years.

DIVIDEND	REINVESTMENT	AND	SHARE	PURCHASE	PLAN
Our	Dividend	Reinvestment	and	Share	Purchase	Plan	provides	shareholders	of	record	with	a	convenient	method	for	purchasing	shares	of	Otter	Tail	
Corporation	common	stock.	Approximately	83	percent	of	eligible	shareowners	holding	approximately	10	percent	of	our	common	shares	are	
enrolled.	Through	this	plan,	participants	may	have	their	dividends	automatically	reinvested	in	additional	shares	without	paying	any	brokerage	fees	
or	service	charges.	Shareholders	also	may	contribute	a	minimum	of	$10	and	a	maximum	of	$120,000	annually.	Automatic	withdrawal	from	a	
checking	or	savings	account	is	available	for	this	service.	Shareholders	also	may	sell	shares	through	the	plan.	Existing	Otter	Tail	shareholders	and	
new	investors	can	enroll	online	through	shareowneronline.com.	For	the	first	purchase,	the	minimum	investment	is	$250.	For	more	information,	
contact	Shareholder	Services.

ELECTRONIC	DIVIDEND	DEPOSIT
You	can	arrange	for	electronic	deposit	of	your	dividends	directly	to	your	checking	or	savings	accounts.	For	authorization	materials,	
contact	Shareholder	Services.

STOCK	CERTIFICATES	AND	DIRECT	REGISTRATION	SYSTEM	(DRS)
Replacing	missing	certificates	is	a	costly	and	time-consuming	process	so	you	should	keep	a	separate	record	of	the	certificate	number,	purchase	
date,	date	of	issue,	price	paid,	and	exact	registration	name.	If	you	are	enrolled	in	the	Dividend	Reinvestment	and	Share	Purchase	Plan,	you	have	
the	option	of	depositing	your	common	certificates	into	your	plan	account.	We	also	offer	DRS	as	a	method	of	holding	your	shares	in	book-entry	
form,	which	eliminates	the	need	to	hold	stock	certificates.
