from $79.6 million (20.7% of sales).  The Tax Cuts and Jobs 
Act enacted in December 2017 had a beneficial impact on  
our corporate tax rate, which was lowered from 35% to 21%.  
Due to this change, our income tax provision benefited by

Earnings per share on a fully diluted basis were $1.03 versus 
$1.00 per share a year ago.

STRONG FINANCIAL CONDITION
Our  financial  condition  was  quite  strong  at  December  31, 
2017.  The current ratio was 3.1:1, with cash and short-term 
investments of $30.4 million. Our capital expenditures in the 
past  year  were  $41.7  million  and  we  paid  cash  dividends  
of  $13.7  million.  During  2017  we  purchased  AAON  

stock  from  our  employees’  401(k)  plan  amounting  to  
approximately $16.3 million.  We continue to operate free 
of  debt.   Total  stockholders’  equity  was  $237.2  million  or  
return  on  average  
share.  Our 
$1.03  per  diluted 
stockholder  equity  was  24.6%.  Aided  by  a  3%  price  
increase  implemented  in  November  2017,  our  backlog  at 
December 31, 2017 climbed 65.4% to $81.2 million, versus 
$49.1 million for the same period a year ago.

During  the  past  five  years  we  have  made  total  capital  
expenditures of $114.4 million and total dividend payouts 
of $55.4 million.  Our cash flow generation combined with 
our capital position enabled the Company to accommodate 
these expenses while excess free cash flow was sufficient to 
repurchase $113 million of stock during the same period.

CAPITAL EXPENDITURES
Over the past two decades we have worked diligently to earn 
a reputation as one of the most technologically innovative  
producers of the highest quality and most efficient products 
in the HVAC industry.  In order to sustain this lofty reputation, 
we must continue to expend both the financial and human 
capital necessary to maintain that industry position.

For  2018  we  are  projecting  capital  expenditures  of  
approximately  $53  million,  the  highest 
in  the  
Company’s history.

For 2018 we estimate capital expenditures of $53 million.  
The completion of the new Norman Asbjornson Innovation 
Center is anticipated to cost $8.0 million and we will spend 
approximately $18.0 million to install two additional WSHP 
assembly  lines.    The  remainder  of  our  expenditures  will  
be devoted to the repair and replacement of equipment as 
well as the expansion of our plant.  It is important to note 
that  over  the  past  five  years  (2013-2017)  we  have  spent  
approximately $114.4 million on our plant and equipment 
and this year we expect to witness another record year of 
capital spending.

“ONE AAON” INITIATIVE
At  AAON,  we  are  constantly  challenging  ourselves  and 
searching  for  ways  to  improve.  In  this  regard,  we  are  
currently  working  on  ways  to  better  integrate  our  Tulsa,

Oklahoma and Longview, Texas locations to ensure a more 
unified culture and cohesive approach in all aspects of our 
business.  We have labeled this endeavor the “One AAON” 
initiative.

dedicated  customer  service  staffing  levels  and  strive  for 
all customer service calls to be answered in less than three 
rings.  Additionally, customer service emails are processed 
by the same dedicated customer service personnel, which 
allows us to better monitor customer service activities and 
also  require  enhanced accountability  from  our  personnel.

to our Tulsa facility’s significant research and development

departments,  as  well  as  our  Manufacturing  Engineering  
departments,  and  are  confident  our  efforts  will  result  in 
AAON achieving more consistent product design regardless 
of location of manufacture.

The  changes  brought  about  to  date  by  our  One  AAON  
initiative  have  been  recognized  and  well  received  by  our  
independent  sales  representatives  and  customers.    We 
have  several  other  areas  of  focus  for  our  One  AAON  
initiative  and  we  look  forward  to  continuing  this  effort  
during 2018 and  beyond.  We are confident the end result  
will  be  a  company—One  AAON—which  is  marked  by  a  
unified  culture  and  cohesive  approach  in  operating  its  
business and interacting with its customers and suppliers.

AAON  was  also  pleased  to  have  each  of  its  WH  Series  
Water-Source Heat Pump, V3 Series Energy Recovery Wheel 
Air  Handling  Unit,  and Touchscreen  Controller  voted  2017 
Product of the Year by the readers of Consulting-Specifying 
Engineer,  a  monthly  publication  with  a  circulation  of  over 
47,000  mechanical,  electrical  and  plumbing  engineers.  
These  awards  highlight  our  commitment  to  designing  
innovative  HVAC  products  of  the  highest  quality  and  
performance.

RECOGNITION AND AWARDS
AAON  was  recognized  for  excellence  in  product  design  in 
the  14th  annual  Dealer  Design  Awards  Program  sponsored

OUTLOOK
As we enter our 30th year of operations, we now more than 
ever recognize the need to maintain our aggressive posture 
for our capital expenditure and research and development 
efforts  as  well  as  our  pursuit  and  recruitment  of  skilled  
personnel.

We  have  posted  an  excellent 
record  of  sales  and  
earnings growth and we look forward to an acceleration of 
growth  aided  by  new  product  introductions,  the  Norman  
Asbjornson  Innovation  Center  research  and  development 
testing  laboratory  as  well  as  the  change  in  operating  
philosophy  creating  One  AAON.  We  can  achieve  our  
goals with the continuing support and cooperation of our 
customers, sales representatives and stockholders, combined 
with the total commitment of our employees, all of whose 
names appear at the end of this report.

On  Monday,  October  29,  2018,  we  have  been  invited  by 
NASDAQ to ring the opening bell for trading on the NASDAQ

Forward-Looking Statements

This Annual Report includes “forward-looking statements” within the meaning of the Private Securities Litigation 
Reform Act  of  1995. Words  such  as  “expects”,  “anticipates”,  “intends”,  “plans”,  “believes”,  “seeks”,  “estimates”, 
“should”, “will”, and variations of such words and similar expressions are intended to identify such forward-looking 
statements. These  statements  are  not  guarantees  of  future  performance  and  involve  certain  risks,  uncertainties  and 
assumptions, which are difficult to predict. Therefore, actual outcomes and results may differ materially from what is 
expressed or forecasted in such forward-looking statements. Readers are cautioned not to place undue reliance on these 
forward-looking statements, which speak only as of the date on which they are made. We undertake no obligations to 
update  publicly  any  forward-looking  statements,  whether  as  a  result  of  new  information,  future  events  or

PART I

Item 1.  Business.

General Development and Description of Business

AAON, Inc., a Nevada corporation, ("AAON Nevada") was incorporated on August 18, 1987. Our operating subsidiaries 
include AAON, Inc., an Oklahoma corporation, and AAON Coil Products, Inc., a Texas corporation. Unless the context 
otherwise requires, references in this Annual Report to “AAON,” the “Company”, “we”, “us”, “our”, or “ours” refer 
to AAON Nevada and our subsidiaries.

We  are  engaged  in  the  engineering,  manufacturing,  marketing  and  sale  of  air  conditioning  and  heating  equipment 
consisting of standard, semi-custom and custom rooftop units, chillers, packaged outdoor mechanical rooms, air handling 
units, makeup air units, energy recovery units, condensing units, geothermal/water-source heat pumps and coils.

Products and Markets

Our products serve the commercial and industrial new construction and replacement markets. To date, our sales have 
been primarily to the domestic market. Foreign sales accounted for approximately $14.6 million, $14.7 million and 
$14.6 million of our sales in 2017, 2016 and 2015, respectively.  As a percent of sales, foreign sales accounted for 
approximately 4% of our net sales in each of those years.

Our rooftop and condensing unit markets primarily consist of units installed on commercial or industrial structures of 
generally less than ten stories in height. Our air handling units, self-contained units, geothermal/water-source heat 
pumps, chillers, packaged outdoor mechanical rooms and coils are suitable for all sizes of commercial and industrial 
buildings.

The size of these markets is determined primarily by the number of commercial and industrial building completions. 
The replacement market consists of products installed to replace existing units/components that are worn or damaged. 
Currently, over half of the industry's market consists of replacement units.

The commercial and industrial new construction market is subject to cyclical fluctuations in that it is generally tied to 
housing starts, but has a lag factor of six to 18 months. Housing starts, in turn, are affected by such factors as interest 
rates, the state of the economy, population growth and the relative age of the population. When new construction is 
down, we emphasize the replacement market.

Based on our 2017 sales of $405 million, we estimate that we have approximately a 12% share of the greater than five 
ton rooftop market and a 2% share of the less than five ton market. Approximately 55% of our sales were generated 
from  the  renovation  and  replacement  markets  and  45%  from  new  construction. The  percentage  of  sales  for  new 
construction vs. replacement to particular customers is related to the customer’s stage of development.

1

We purchase certain components, fabricate sheet metal and tubing and then assemble and test the finished products. 
Our primary finished products consist of a single unit system containing heating and cooling in a self-contained cabinet, 
referred to in the industry as "unitary products". Our other finished products are chillers, packaged outdoor mechanical 
rooms, coils, air handling units, condensing units, makeup air units, energy recovery units, rooftop units and geothermal/ 
water-source heat pumps. 

We offer three groups of rooftop units: the RQ Series, consisting of five cooling sizes ranging from two to six tons; the 
RN Series, offered in 28 cooling sizes ranging from six to 140 tons; and the RL Series, which is offered in 21 cooling 
sizes ranging from 45 to 240 tons.  

We also offer the SA, SB and M2 Series as indoor packaged, water-cooled or geothermal/water-source heat pump self-
contained units with cooling capacities of three to 70 tons.

Our small packaged geothermal/water-source heat pump units consist of the WH Series horizontal configuration and 
WV Series vertical configuration, both from one-half to five tons.

We manufacture a LF Series chiller, air-cooled, a LN Series chiller, air-cooled, and a LZ Series chiller and packaged 
outdoor mechanical room, which are available in both air-cooled condensing and evaporative-cooled configurations, 
covering a range of four to 540 tons. BL Series boiler outdoor mechanical rooms are also available with 400-6,000 
MBH heating capacity. FZ Series fluid cooler outdoor mechanical rooms are also available with a range of 50 to 450 
tons. 

We offer four groups of condensing units: the CB Series, two to five tons; the CF Series, two to 70 tons; the CN Series, 
55 to 140 tons; and the CL Series, 45 to 230 tons.

Our air handling units consist of the indoor F1, H3 and V3 Series and the modular M2 and M3 Series, as well as air 
handling unit configurations of the RQ, RN, RL and SA Series units.  

Our energy recovery option applicable to our RQ, RN, RL and SB units, as well as our H3, V3, M2 and M3 Series air 
handling units, respond to the U.S. Clean Air Act mandate to increase fresh air in commercial structures. Our products 
are designed to compete on the higher quality end of standardized products.

Performance characteristics of our products range in cooling capacity from one-half to 540 tons and in heating capacity 
from 7,200 to 9,000,000 BTUs. All of our products meet the Department of Energy's (“DOE”) minimum efficiency 
standards, which define the maximum amount of energy to be used in producing a given amount of cooling. Many of 
our units far exceed these minimum standards and are among the highest efficiency units currently available.

A typical commercial building installation requires one ton of air conditioning for every 300-400 square feet or, for a 
100,000 square foot building, 250 tons of air conditioning, which can involve multiple units. 

Major Customers

One customer, Texas AirSystems, accounted for 10% or more of our sales during 2017 and 2016. No customer accounted 
for 10% or more of our sales during 2015.

Sources and Availability of Raw Materials

The  most  important  materials  we  purchase  are  steel,  copper  and  aluminum,  which  are  obtained  from  domestic 
suppliers. We also purchase from other domestic manufacturers certain components, including compressors, electric 
motors and electrical controls used in our products. We attempt to obtain the lowest possible cost in our purchases of 
raw materials and components, consistent with meeting specified quality standards. We are not dependent upon any 
one source for raw materials or the major components of our manufactured products. By having multiple suppliers, we 
believe that we will have adequate sources of supplies to meet our manufacturing requirements for the foreseeable 
future.

We have not been significantly impacted by the Dodd-Frank Wall Street Reform and Consumer Protection Act (the 
"Dodd-Frank Act") that contains provisions to improve transparency and accountability concerning the supply of certain 
minerals, known as "conflict minerals", originating from the Democratic Republic of Congo and adjoining countries. 

2

We attempt to limit the impact of price fluctuations on these materials by entering into cancellable and non-cancellable 
fixed price contracts with our major suppliers for periods of six to 18 months. We expect to receive delivery of raw 
materials from our fixed price contracts for use in our manufacturing operations.

Representatives

We  employ  a  sales  staff  of  33  individuals  and  utilize  approximately  62  independent  manufacturer  representatives' 
organizations ("Representatives") having 100 offices to market our products in the United States and Canada. We also 
have one international sales organization, which utilizes 12 distributors in other countries. Sales are made directly to 
the contractor or end user, with shipments being made from our Tulsa, Oklahoma, and Longview, Texas, plants to the 
job site.

Our products and sales strategy focuses on niche markets. The targeted markets for our equipment are customers seeking 
products of better quality than offered, and/or options not offered, by standardized manufacturers.

To support and service our customers and the ultimate consumer, we provide parts availability through our sales offices. 
We also have factory service organizations at each of our plants. Additionally, a number of the Representatives we 
utilize have their own service organizations, which, in connection with us, provide the necessary warranty work and/
or normal service to customers.

Warranties

Our product warranty policy is:  the earlier of one year from the date of first use or 18 months from date of shipment 
for parts only; an additional four years for compressors (if applicable); 15 years on aluminized steel gas-fired heat 
exchangers (if applicable); 25 years on stainless steel heat exchangers (if applicable); and ten years on gas-fired heat 
exchangers in RL products (if applicable). Our warranty policy for the RQ series covers parts for two years from date 
of unit shipment and labor for one year from date of unit shipment. Our warranty policy for the WH and WV Series 
geothermal/water-source heat pumps covers parts for five years from the date of manufacture.

The Company also sells extended warranties on parts for various lengths of time ranging from six months to ten years. 
Revenue for these separately priced warranties is deferred and recognized on a straight-line basis over the separately 
priced warranty period.

Research and Development

Our  products  are  engineered  for  performance,  flexibility  and  serviceability. This  has  become  a  critical  factor  in 
competing in the heating, ventilation and air conditioning ("HVAC") equipment industry. We must continually develop 
new and improved products in order to compete effectively and to meet evolving regulatory standards in all of our 
major product lines.

All of our Research and Development ("R&D") activities are self-sponsored, rather than customer-sponsored. R&D 
activities have involved the RQ, RN and RL (rooftop units), F1, H3, V3, M2 and M3 (air handling units), LF, LN and 
LZ (chillers), CB, CF and CN (condensing units), SA and SB (self-contained units), WH and WV (water-source heat 
pumps), FZ (fluid coolers) and BL (boilers), as well as component evaluation and refinement, development of control 
systems and new product development. We incurred R&D expenses of approximately $13.0 million, $12.0 million and 
$7.5 million in 2017, 2016 and 2015, respectively.
Backlog

Our backlog as of February 1, 2018 was approximately $64.9 million compared to approximately $53.5 million as of 
February 1, 2017. The current backlog consists of orders considered by management to be firm and generally are filled 
on average within approximately 60 to 90 days after an order is deemed to become firm; however, the orders are subject 
to cancellation by the customers.

Working Capital Practices

Working capital practices in the industry center on inventories and accounts receivable. Our management regularly 
reviews our working capital with a view of maintaining the lowest level consistent with requirements of anticipated 
levels of operation. Our greatest needs arise during the months of July - November, the peak season for inventory 
(primarily purchased material) and accounts receivable. Our working capital requirements are generally met by cash 
flow from operations and a bank revolving credit facility, which currently permits borrowings up to $30 million and 
had no balance outstanding at December 31, 2017. We believe that we will have sufficient funds available to meet our 
working capital needs for the foreseeable future.

Seasonality

Sales of our products are moderately seasonal with the peak period being July - November of each year due to timing 
of construction projects being directly related to warmer weather.

Competition

In the standardized market, we compete primarily with Lennox International, Inc., Trane (Ingersoll Rand Limited), 
York (Johnson Controls Inc.) and Carrier (United Technologies Corporation). All of these competitors are substantially 
larger  and  have  greater  resources  than  we  do. Our  products  compete  on  the  basis  of  total  value,  quality,  function, 
serviceability, efficiency, availability of product, product line recognition and acceptability of sales outlet. However, 
in new construction where the contractor is the purchasing decision maker, we are often at a competitive disadvantage 
because of the emphasis placed on initial cost. In the replacement market and other owner-controlled purchases, we 
have a better chance of getting business since quality and long-term cost are generally taken into account.

Employees

As  of  February  12,  2018,  we  employed  1,991  permanent  employees. Our  employees  are  not  represented  by 
unions. Management considers its relations with our employees to be good.

Patents, Trademarks, Licenses and Concessions

We do not consider any patents, trademarks, licenses or concessions to be material to our business operations, other 
than patents issued regarding our energy recovery wheel option, blower, gas-fired heat exchanger, evaporative-cooled 
condenser de-superheater and low leakage damper which have terms of 20 years with expiration dates ranging from 
2018 to 2033. 

Environmental Matters

Laws concerning the environment that affect or could affect our operations include, among others, the Clean Water 
Act, the Clean Air Act, the Resource Conservation and Recovery Act, the Occupational Safety and Health Act, the 
National Environmental Policy Act, the Toxic Substances Control Act, regulations promulgated under these Acts, and 
any  other  federal,  state  or  local  laws  or  regulations  governing  environmental  matters. We  believe  that  we  are  in 
compliance with these laws and that future compliance will not materially affect our earnings or competitive position.

Item 1A.  Risk Factors.

4

The following risks and uncertainties may affect our performance and results of operations. The discussion below 
contains "forward-looking statements" as outlined in the Forward-Looking Statements section above. Our ability to 
mitigate risks may cause our future results to materially differ from what we currently anticipate. Additionally, the 
ability of our competitors to react to material risks will affect our future results.

Our business can be hurt by economic conditions.

Our business is affected by a number of economic factors, including the level of economic activity in the markets in 
which we operate. Sales in the commercial and industrial new construction markets correlate to the number of new 
homes and buildings that are built, which in turn is influenced by cyclical factors such as interest rates, inflation, 
consumer spending habits, employment rates and other macroeconomic factors over which we have no control. In the 
HVAC business, a decline in economic activity as a result of these cyclical or other factors typically results in a decline 
in new construction and replacement purchases which could impact our sales volume and profitability.

We may be adversely affected by problems in the availability, or increases in the prices, of raw materials and 
components.

Problems in the availability, or increases in the prices, of raw materials or components could depress our sales or 
increase the costs of our products. We are dependent upon components purchased from third parties, as well as raw 
materials such as steel, copper and aluminum. Occasionally, we enter into cancellable and non-cancellable contracts 
on terms from six to 18 months for raw materials and components at fixed prices. However, if a key supplier is unable 
or unwilling to meet our supply requirements, we could experience supply interruptions or cost increases, either of 
which could have an adverse effect on our gross profit.

We risk having losses resulting from the use of non-cancellable fixed price contracts.

Historically, we have attempted to limit the impact of price fluctuations on commodities by entering into non-cancellable 
fixed price contracts with our major suppliers for periods of six to 18 months. We expect to receive delivery of raw 
materials from our fixed price contracts for use in our manufacturing operations. These fixed price contracts are not 
accounted for using hedge accounting since they meet the normal purchases and sales exemption.

We may not be able to successfully develop and market new products.

Our future success will depend upon our continued investment in research and new product development and our ability 
to continue to achieve new technological advances in the HVAC industry. Our inability to continue to successfully 
develop and market new products or our inability to implement technological advances on a pace consistent with that 
of our competitors could lead to a material adverse effect on our business and results of operations.

We may incur material costs as a result of warranty and product liability claims that would negatively affect 
our profitability.

The development, manufacture, sale and use of our products involve a risk of warranty and product liability claims. Our 
product liability insurance policies have limits that, if exceeded, may result in material costs that would have an adverse 
effect on our future profitability. In addition, warranty claims are not covered by our product liability insurance and 
there may be types of product liability claims that are also not covered by our product liability insurance.

5

We may not be able to compete favorably in the highly competitive HVAC business.

Competition in our various markets could cause us to reduce our prices or lose market share, which could have an 
adverse  effect  on  our  future  financial  results. Substantially  all  of  the  markets  in  which  we  participate  are  highly 
competitive. The most significant competitive factors we face are product reliability, product performance, service and 
price, with the relative importance of these factors varying among our product line. Other factors that affect competition 
in the HVAC market include the development and application of new technologies and an increasing emphasis on the 
development of more efficient HVAC products. Moreover, new product introductions are an important factor in the 
market categories in which our products compete. Several of our competitors have greater financial and other resources 
than we have, allowing them to invest in more extensive research and development. We may not be able to compete 
successfully  against  current  and  future  competition  and  current  and  future  competitive  pressures  faced  by  us  may 
materially adversely affect our business and results of operations.

The loss of Norman H. Asbjornson could impair the growth of our business.

Norman H. Asbjornson, our founder, has served as our Chief Executive Officer from inception to date and President 
from inception to November 2016. He has provided the leadership and vision for our strategy and growth. Although 
important responsibilities and functions have been delegated to other highly experienced and capable management 
personnel, and our products are technologically advanced and well positioned for sales well into the future, the death, 
disability or retirement of Mr. Asbjornson could impair the growth of our business. We do not have an employment 
agreement with Mr. Asbjornson.

The Board of Directors attempts to manage this risk by continually engaging in succession planning concerning Mr. 
Asbjornson (as well as other key management personnel), as demonstrated by the Board's appointment of Gary D. 
Fields as President of AAON in November 2016.

Our business is subject to the risks of interruptions by cybersecurity attacks.

We depend upon information technology infrastructure, including network, hardware and software systems to conduct 
our business. Despite our implementation of network and other cybersecurity  measures, our information technology 
system and networks could be disrupted or experience a security breach from computer viruses, break-ins and similar 
disruptions from unauthorized tampering with our computer systems. Our security measures may not be adequate to 
protect against highly targeted sophisticated cyber-attacks, or other improper disclosures of confidential and/or sensitive 
information. Additionally, we may have access to confidential or other sensitive information of our customers, which, 
despite our efforts to protect, may be vulnerable to security breaches, theft, or other improper disclosure. Any cyber-
related attack or other improper disclosure of confidential information could have a material adverse effect on our 
business, as well as other negative consequences, including significant damage to our reputation, litigation, regulatory 
actions and increased cost.  

Exposure to environmental liabilities could adversely affect our results of operations.

Our future profitability could be adversely affected by current or future environmental laws. We are subject to extensive 
and changing federal, state and local laws and regulations designed to protect the environment in the United States and 
in other parts of the world. These laws and regulations could impose liability for remediation costs and result in civil 
or criminal penalties in case of non-compliance. Compliance with environmental laws increases our costs of doing 
business. Because these laws are subject to frequent change, we are unable to predict the future costs resulting from 
environmental compliance.

We are subject to potentially extreme governmental regulations.

We always face the possibility of new governmental regulations which could have a substantial or even extreme negative 
effect on our operations and profitability. Negotiations during the summer of 2013 mitigated some of the negative 
effects of the Department of Energy Final Rule, Regulatory Identification No. 1904-AC23, published on March 7, 2011. 
However, certain additional testing and listing requirements are still in place and scheduled to be phased in.

6

 
Several other intrusive component part governmental regulations are in process. If these proposals become final rules, 
the effect would be the regulation of compressors and fans in products for which the Department of Energy does not 
have current authority. This could affect equipment we currently manufacture and could have an impact on our product 
design, operations and profitability.  

The Dodd-Frank Wall Street Reform and Consumer Protection Act contains provisions to improve transparency and 
accountability concerning the supply of certain minerals, known as "conflict minerals", originating from the Democratic 
Republic of Congo and adjoining countries. As a result, in August 2012, the SEC adopted annual disclosure and reporting 
requirements for those companies who use conflict minerals in their products. Accordingly, we began our reasonable 
country of origin inquiries in fiscal year 2013, with initial disclosure requirements beginning in May 2014. There are 
costs associated with complying with these disclosure requirements, including for due diligence to determine the sources 
of conflict minerals used in our products and other potential changes to products, processes or sources of supply as a 
consequence of such verification activities. The implementation of these rules could adversely affect the sourcing, 
supply and pricing of materials used in our products. As there may be only a limited number of suppliers offering 
"conflict free" conflict minerals, we cannot be sure that we will be able to obtain necessary conflict minerals from such 
suppliers in sufficient quantities or at competitive prices. Also, we may face reputational challenges if we determine 
that certain of our products contain minerals not determined to be conflict free or if we are unable to sufficiently verify 
the origins for all conflict minerals used in our products through the procedures we may implement.

We are subject to adverse changes in tax laws.

Our tax expense or benefits could be adversely affected by changes in tax provisions, unfavorable findings in tax 
examinations or differing interpretations by tax authorities. We are unable to estimate the impact that current and future 
tax proposals and tax laws could have on our results of operations. We are currently subject to state and local tax 
examinations for which we do not expect any major assessments.

We are subject to international regulations that could adversely affect our business and results of operations. 

Due to our use of representatives in foreign markets, we are subject to many laws governing international relations, 
including those that prohibit improper payments to government officials and commercial customers, and restrict where 
we can do business, what information or products we can supply to certain countries and what information we can 
provide to a non-U.S. government, including but not limited to the Foreign Corrupt Practices Act, U.K. Bribery Act 
and the U.S. Export Administration Act. Violations of these laws, which are complex, may result in criminal penalties 
or sanctions that could have a material adverse effect on our business, financial condition and results of operations.

Operations may be affected by natural disasters, especially since most of our operations are performed at a 
single location.

Natural disasters such as tornadoes and ice storms, as well as accidents, acts of terror, infection and other factors beyond 
our control could adversely affect our operations. Especially, as our facilities are in areas where tornadoes are likely 
to occur, and the majority of our operations are at our Tulsa facilities, the effects of natural disasters and other events 
could damage our facilities and equipment and force a temporary halt to manufacturing and other operations, and such 
events could consequently cause severe damage to our business. We maintain insurance against these sorts of events; 
however, this is not guaranteed to cover all the losses and damages incurred.

If we are unable to hire, develop or retain employees, it could have an adverse effect on our business.

We compete to hire new employees and then seek to train them to develop their skills. We may not be able to successfully 
recruit, develop and retain the personnel we need. Unplanned turnover or failure to hire and retain a diverse, skilled 
workforce, could increase our operating costs and adversely affect our results of operations. 

Variability in self-insurance liability estimates could impact our results of operations. 

We self-insure for employee health insurance and workers' compensation insurance coverage up to a predetermined 
level, beyond which we maintain stop-loss insurance from a third-party insurer for claims over $200,000 and $750,000 
for employee health insurance claims and workers' compensation insurance claims, respectively. Our aggregate exposure 
varies from year to year based upon the number of participants in our insurance plans. We estimate our self-insurance 
liabilities using an analysis provided by our claims administrator and our historical claims experience. Our accruals 

7

for insurance reserves reflect these estimates and other management judgments, which are subject to a high degree of 
variability. If the number or severity of claims for which we self-insure increases, it could cause a material and adverse 
change to our reserves for self-insurance liabilities, as well as to our earnings. 

Item 1B.  Unresolved Staff Comments.

None.

Item 2.  Properties.

As of December 31, 2017, we own all of our facilities, consisting of approximately 1.55 million square feet of space 
for office, manufacturing, warehouse, assembly operations and parts sales in Tulsa, Oklahoma, and Longview, Texas. We 
believe that our facilities are well maintained and are in good condition and suitable for the conduct of our business.

Our plant and office facilities in Tulsa, Oklahoma, consist of a 342,000 sq. ft. building (327,000 sq. ft. of manufacturing/
warehouse space and 15,000 sq. ft. of office space) located on a 12-acre tract of land at 2425 South Yukon Avenue, and 
a 940,000 sq. ft. manufacturing/warehouse building and a 70,000 sq. ft. office building located on an approximately 
78-acre tract of land across the street from the original facility (2440 South Yukon Avenue) (the "Tulsa facilities").

Our  manufacturing area  is in  heavy industrial  type buildings, with  some coverage by  overhead  cranes, containing 
manufacturing  equipment  designed  for  sheet  metal  fabrication  and  metal  stamping. The  manufacturing  equipment 
contained  in  the  facilities  consists  primarily  of  automated  sheet  metal  fabrication  equipment,  supplemented  by 
presses. Assembly lines consist of six cart-type conveyor lines and one roller-type conveyor line with variable line 
speed adjustment, which are motor driven. Subassembly areas and production line manning are based upon line speed.

In 2017, construction continued on a new engineering research and development laboratory at the Tulsa facilities, since 
named the Norman Asbjornson Innovation Center.  The three-story 134,000 square foot facility will be both an acoustical 
and a performance measuring laboratory.  The new facility will consist of ten test chambers allowing AAON to meet 
and maintain industry certifications.  

Our operations in Longview, Texas, are conducted in a plant/office building at 203-207 Gum Springs Road, containing 
263,000 sq. ft. on 33.0 acres. The manufacturing area (approximately 256,000 sq. ft.) is located in three 120-foot wide 
sheet  metal  buildings  connected  by  an  adjoining  structure. The  remaining  7,000  square  feet  are  utilized  as  office 
space. The facility is built for light industrial manufacturing.

Item 3.  Legal Proceedings.

We are not a party to any pending legal proceeding which management believes is likely to result in a material liability 
and no such action has been threatened against us, or, to the best of our knowledge, is contemplated.

Item 4.  Mine Safety Disclosure.

Not applicable.

Use of Non-GAAP Financial Measure

To  supplement  the  Company's  consolidated  financial  statements  presented  in  accordance  with  generally  accepted 
accounting principles ("GAAP"), an additional non-GAAP financial measure is provided and reconciled in the following 
table. The Company believes that this non-GAAP financial measure, when considered together with the GAAP financial 
measures, provides information that is useful to investors in understanding period-over-period operating results. The 
Company believes that this non-GAAP financial measure enhances the ability of investors to analyze the Company’s 
business trends and operating performance. 

EBITDAX 

EBITDAX (as defined below) is presented herein and reconciled from the GAAP measure of net income because of 
its wide acceptance by the investment community as a financial indicator of a company's ability to internally fund 
operations. 

The Company defines EBITDAX as net income, plus (1) depreciation, (2) amortization of bond premiums, (3) share-
based compensation, (4) interest (income) expense and (5) income tax expense. EBITDAX is not a measure of net 
income or cash flows as determined by GAAP. 

The  Company's  EBITDAX  measure  provides  additional  information  which  may  be  used  to  better  understand  the 
Company’s  operations.  EBITDAX  is  one  of  several  metrics  that  the  Company  uses  as  a  supplemental  financial 
measurement in the evaluation of its business and should not be considered as an alternative to, or more meaningful 
than, net income, as an indicator of operating performance. Certain items excluded from EBITDAX are significant 
components in understanding and assessing a company's financial performance. EBITDAX, as used by the Company, 
may not be comparable to similarly titled measures reported by other companies. The Company believes that EBITDAX 
is a widely followed measure of operating performance and is one of many metrics used by the Company’s management 
team, and by other users of the Company’s consolidated financial statements.

Item 7.  Management's Discussion and Analysis of Financial Condition and Results of Operations.

Overview

We engineer, manufacture, market and sell air conditioning and heating equipment consisting of standard, semi-custom 
and custom rooftop units, chillers, packaged outdoor mechanical rooms, air handling units, makeup air units, energy 
recovery units, condensing units, geothermal/water-source heat pumps and coils. These products are marketed and sold 
to retail, manufacturing, educational, lodging, supermarket, medical and other commercial industries. We market our 
products to all 50 states in the United States and certain provinces in Canada.  

Our business can be affected by a number of economic factors, including the level of economic activity in the markets 
in which we operate. The recent uncertainty of the economy has negatively impacted the commercial and industrial 
new construction markets. A further decline in economic activity could result in a decrease in our sales volume and 
profitability. Sales in the commercial and industrial new construction markets correlate closely to the number of new 
homes and buildings that are built, which in turn is influenced by cyclical factors such as interest rates, inflation, 
consumer spending habits, employment rates and other macroeconomic factors over which we have no control.

We sell our products to property owners and contractors through a network of manufacturers’ representatives and our 
internal sales force. The demand for our products is influenced by national and regional economic and demographic 
factors. The commercial and industrial new construction market is subject to cyclical fluctuations in that it is generally 
tied to housing starts, but has a lag factor of six to 18 months. Housing starts, in turn, are affected by such factors as 
interest rates, the state of the economy, population growth and the relative age of the population. When new construction 
is down, we emphasize the replacement market. The new construction market in 2017 continued to be unpredictable 
and uneven. Thus, throughout the year, we emphasized promotion of the benefits of AAON equipment to property 
owners in the replacement market. 

The principal components of cost of goods sold are labor, raw materials, component costs, factory overhead, freight 
out and engineering expense. The principal high volume raw materials used in our manufacturing processes are steel, 
copper and aluminum and are obtained from domestic suppliers. We also purchase from domestic manufacturers certain 
components, including compressors, motors and electrical controls.

The price levels of our raw materials fluctuate given that the market continues to be volatile and unpredictable as a 
result of the uncertainty related to the U.S. economy and global economy. For the year ended December 31, 2017, the 
prices for copper, galvanized steel and stainless steel increased approximately 6.2%, 15.8% and 4.4%, respectively, 
from a year ago, while the price for aluminum remained relatively unchanged  from a year ago. For the year ended 
December 31, 2016, the prices for copper, galvanized steel and stainless steel decreased approximately 4.8%, 9.5%, 
and 12.3%, respectively, from 2015, while the price for aluminum increased 0.0% from 2015.

We attempt to limit the impact of price fluctuations on these materials by entering into cancellable and non-cancellable 
fixed price contracts with our major suppliers for periods of six to 18 months. We expect to receive delivery of raw 
materials from our fixed price contracts for use in our manufacturing operations. 

12

 
 
The following are highlights of our results of operations, cash flows, and financial condition:

•  We spent $41.7 million in capital expenditures in 2017, an increase of $15.1 million from the $26.6 million
spent in 2016, primarily due to construction projects related to our new research and development lab, water-
source heat pump production line, as well as other internal development projects.

•  We paid cash dividends of $13.7 million in 2017 compared to $12.7 million in 2016. 

•  We experienced increases in our warranty expense due to refinements and changes to our warranty process.

While we did see an 11.9%  increase in the volume of units sold, most of that increase was in Water-Source Heat Pumps 
which have a lower price per unit than our other products.  As such, total net sales did not increase by the same percentage 
as our volume.

The overall increase in SG&A was primarily due to increased warranty expenses. The Company has been working on 
modifications  and  refinements  to  its  warranty  policy. These  modifications  more  clearly  define  what  qualifies  as  a 
warranty claim and place a deadline for when claims may be submitted.

The Tax Cuts and Jobs Act (the "Act") was enacted on December 22, 2017.  As a result of the changes provided under 
the Act, the Company adjusted its deferred tax assets and liabilities existing at the date of enactment using the newly 
enacted rates for the periods when they are expected to be realized.    This remeasurement resulted in a benefit to income 
taxes of $4.4 million.

The Company early adopted ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, applying 
the changes for excess tax benefits and tax deficiencies prospectively. As a result, excess tax benefits and deficiencies 
are reported as an income tax benefit or expense on the statement of income rather than as a component of additional 
paid-in capital on the statement of equity. Excess tax benefits and deficiencies are treated as discrete items to the income 
tax provision in the reporting period in which they occur.  For the twelve months ended December 31, 2016, the Company 
recorded $2.1 million in excess tax benefits as an income tax benefit.

Liquidity and Capital Resources

Our working capital and capital expenditure requirements are generally met through net cash provided by operations 
and the occasional use of the revolving bank line of credit based on our current liquidity at the time.

Our  cash  and  cash  equivalents  decreased  $2.7  million  from  December 31,  2016  to  December 31,  2017.  As  of 
December 31, 2017, we had $21.5 million in cash and cash equivalents.  

As of December 31, 2017, we had certificates of deposit of $2.9 million and investments held to maturity at amortized 
cost of $6.1 million. These certificates of deposit had maturity dates of one to five months. The investments held to 
maturity at amortized cost had maturity dates of one to four months.

16

 
 
On July 25, 2016 we renewed our line of credit with BOKF, NA dba Bank of Oklahoma, formerly known as Bank of 
Oklahoma, N.A. ("Bank of Oklahoma"). The revolving line of credit matures on July 27, 2018. We expect to renew 
our line of credit in July 2018 with favorable terms. Under the line of credit, there was one standby letter of credit of 
$0.8 million as of December 31, 2017. At December 31, 2017 we have $29.2 million of borrowings available under 
the revolving credit facility. No fees are associated with the unused portion of the committed amount.

As of December 31, 2017 and 2016, there were no outstanding balances under the revolving credit facility. Interest on 
borrowings is payable monthly at LIBOR plus 2.5%. The weighted average interest rate was 3.5% and 3.0% for the 
years ended December 31, 2017 and 2016, respectively.

At December 31, 2017, we were in compliance with all of the covenants under the revolving credit facility. We are 
obligated to comply with certain financial covenants under the revolving credit facility. These covenants require that 
we meet certain parameters related to our tangible net worth and total liabilities to tangible net worth ratio. At December 
31,  2017,  our  tangible  net  worth  was  $237.2  million,  which  meets  the  requirement  of  being  at  or  above  $125.0 
million. Our total liabilities to tangible net worth ratio was 0.3 to 1.0 which meets the requirement of not being above 
2 to 1.

The Board has authorized three stock repurchase programs for the Company. The Company may purchase shares on 
the open market from time to time, up to a total of 5.7 million shares. The Board must authorize the timing and amount 
of these purchases.  Effective May 24, 2016, the Board authorized up to $25.0 million in open market repurchases and 
on June 2, 2016, the Company executed a repurchase agreement in accordance with the rules and regulations of the 
SEC allowing the Company to repurchase an aggregate amount of $25.0 million or a total of approximately 2.0 million 
shares from the open market. The repurchase agreement expired on April 15, 2017. The Company also has a stock 
repurchase arrangement by which employee-participants in our 401(k) savings and investment plan are entitled to have 
shares in AAON, Inc. stock in their accounts sold to the Company. The maximum number of shares to be repurchased 
is contingent upon the number of shares sold by employee-participants. Lastly, the Company repurchases shares of 
AAON, Inc. stock from certain of its directors and employees for payment of statutory tax withholdings on stock 
transactions. Any other repurchases from directors or employees are contingent upon Board approval. All repurchases 
are done at current market prices.

Based  on  historical  performance  and  current  expectations,  we  believe  our  cash  and  cash  equivalents  balance,  the 
projected cash flows generated from our operations, our existing committed revolving credit facility (or comparable 
financing) and our expected ability to access capital markets will satisfy our working capital needs, capital expenditures 
and other liquidity requirements associated with our operations in 2018 and the foreseeable future.

Cash Flows from Investing Activities

The  capital  expenditure  program  for  2018  is  estimated  to  be  approximately  $53.2  million. The  increase  in  capital 
expenditures is primarily due to construction projects related to our new research and development lab, water-source 
heat pump production lines, as well as other internal development projects. Many of these projects are subject to review 
and cancellation at the discretion of our CEO and Board of Directors without incurring substantial charges. 

Cash Flows from Financing Activities

Cash flows used in financing activities decreased slightly due to fewer open market buybacks following the expiration 
of the Company's repurchase agreement in April 2017.

Off-Balance Sheet Arrangements

We are not party to any off-balance sheet arrangements that have or are reasonably likely to have a material current or 
future  effect  on  our  financial  condition,  changes  in  financial  condition,  revenues,  expenses,  results  of  operations, 
liquidity, capital expenditures or capital resources.

Commitments and Contractual Agreements

We had no material contractual purchase agreements as of December 31, 2017.

Contingencies

We are subject to various claims and legal actions that arise in the ordinary course of business. We closely monitor 
these claims and legal actions and frequently consult with our legal counsel to determine whether they may, when 
resolved, have a material adverse effect on our financial position, results of operations or cash flows and we accrue 
and/or disclose loss contingencies as appropriate. We have concluded that the likelihood is remote that the ultimate 
resolution of any pending litigation or claims will be material or have a material adverse effect on the Company's 
business, financial position, results of operations or cash flows.

Critical Accounting Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States 
of America (“US GAAP”) requires management to make estimates and assumptions about future events, and apply 
judgments that affect the reported amounts of assets, liabilities, revenue and expenses in our consolidated financial 
statements and related notes. We base our estimates, assumptions and judgments on historical experience, current trends 
and other factors believed to be relevant at the time our consolidated financial statements are prepared. However, 
because future events and their effects cannot be determined with certainty, actual results could differ from our estimates 
and assumptions, and such differences could be material. We believe the following critical accounting policies affect 
our  more  significant  estimates,  assumptions  and  judgments  used  in  the  preparation  of  our  consolidated  financial 
statements.

Inventory Reserves – We establish a reserve for inventories based on the change in inventory requirements due to 
product line changes, the feasibility of using obsolete parts for upgraded part substitutions, the required parts needed 
for part supply sales, replacement parts and for estimated shrinkage.

Warranty – A provision is made for estimated warranty costs at the time the product is shipped and revenue is recognized. 
The warranty period is:  the earlier of one year from the date of first use or 18 months from date of shipment for parts 
only; an additional four years on compressors (if applicable); 15 years on aluminized steel gas-fired heat exchangers 
(if applicable); 25 years on stainless steel heat exchangers (if applicable); and 10 years on gas-fired heat exchangers 
in RL products (if applicable). With the introduction of the RQ product line in 2010, our warranty policy for the RQ 
series was implemented to cover parts for two years from date of unit shipment and labor for one year from date of 
unit shipment.  Our warranty policy for the WH and WV Series geothermal/water-source heat pumps covers parts for 
five years from the date of manufacture. Warranty expense is estimated based on the warranty period, historical warranty 
trends and associated costs, and any known identifiable warranty issue.

19

Due to the absence of warranty history on new products, an additional provision may be made for such products. Our 
estimated future warranty cost is subject to adjustment from time to time depending on changes in actual warranty 
trends and cost experience. Should actual claim rates differ from our estimates, revisions to the estimated product 
warranty liability would be required.

Stock Compensation – We measure and recognize compensation expense for all share-based payment awards made to 
our employees and directors, including stock options and restricted stock awards, based on their fair values at the time 
of grant. Compensation expense is recognized on a straight-line basis during the service period of the related share-
based compensation award. Forfeitures are accounted for as they occur. The fair value of each option award and restricted 
stock award is estimated on the date of grant using the Black-Scholes-Merton option pricing model. The use of the 
Black-Scholes-Merton  option  valuation  model  requires  the  input  of  subjective  assumptions  such  as:  the  expected 
volatility, the expected term of the options granted, expected dividend yield, and the risk-free rate.

New Accounting Pronouncements

Changes to U.S. GAAP are established by the Financial Accounting Standards Board ("FASB") in the form of accounting 
standards updates ("ASUs") to the FASB's Accounting Standards Codification.

We consider the applicability and impact of all ASUs. ASUs not listed below were assessed and determined to be either 
not applicable or are expected to have minimal impact on our consolidated financial statements and notes thereto.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which requires an entity to 
recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to 
customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. 
In August 2015, with the issuance of ASU 2015-14, the FASB amended the effective date for us to January 1, 2018. 

The following ASUs have been issued in 2016 along with ASU 2014-09 with the same effective dates and transition 
requirements:

•  ASU 2016-08, Principal versus Agent Considerations (Reporting Revenue Gross versus Net), which provides 

implementation guidance for Topic 606 on principal versus agent considerations.

•  ASU  2016-10,  Identifying  Performance  Obligations  and  Licensing,  which  provides  clarification  for  two 
aspects of Topic 606: identifying performance obligations and the licensing implementation guidance.

•  ASU 2016-12, Revenue from Contracts with Customers, which further amends Topic 606. 
•  ASU 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers, 

which further amends Topic 606.

The Company plans to adopt using the retrospective transition method. The Company believes the impact will not be 
material to the consolidated financial statements.  The Company has reviewed all types of customer contracts and gone 
through the five step process outlined in ASU 2014-09 for each type of contract.  The new five step process required 
by ASU 2014-09 provides results substantially consistent with our current revenue recognition policies.  The Company 
has also evaluated the categories to use for the disaggregate revenue disclosures.  The primary change upon adoption 
will be additional disclosures to show disaggregated revenue and further details around our revenue recognition process.  
Once  we adopt ASU 2014-09, we not anticipate that our internal control framework will materially change, but rather 
that existing internal controls will be modified and augmented, as necessary, to consider our new revenue recognition 
policy effective January 1, 2018.

In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial 
Liabilities, which will address certain aspects of recognition, measurement, presentation and disclosure of financial 
instruments. The ASU becomes effective in the annual reporting period beginning after December 31, 2017, including 
interim reporting periods. We do not expect ASU 2016-01 will have a material effect on our consolidated financial 
statements and notes thereto.

In May 2017, the FASB issued ASU 2017-09, Scope of Modification Accounting, which addresses changes to the terms 
or condition of a share-based payment award.  The ASU becomes effective in the annual reporting period beginning 
after December 15, 2017, including interim reporting periods. We do not expect ASU 2017-09 will have a material 
effect on our consolidated financial statements and notes thereto.

Item 7A.  Quantitative and Qualitative Disclosures About Market Risk.

Commodity Price Risk

We are exposed to volatility in the prices of commodities used in some of our products and, occasionally, we use fixed 
price cancellable and non-cancellable contracts with our major suppliers for periods of six to 18 months to manage this

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders
AAON, Inc.

Opinion on the financial statements
We have audited the accompanying consolidated balance sheets of AAON, Inc. (a Nevada corporation) and subsidiaries 
(the “Company”) as of December 31, 2017 and 2016, and the related consolidated statements of income, stockholders’ 
equity,  and  cash  flows  for  each  of  the  three  years  in  the  period  ended  December  31,  2017,  and  the  related  notes 
(collectively referred to as the "financial statements").  In our opinion, the financial statements present fairly, in all 
material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of its 
operations and its cash flows for each of the three years in the period ended December 31, 2017, in conformity with 
accounting principles generally accepted in the United States of America. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States) (“PCAOB”), the Company’s internal control over financial reporting as of December 31, 2017, based on criteria 
established in the 2013 Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations 
of the Treadway Commission (“COSO”), and our report dated February 27, 2018 expressed an unqualified opinion.

Basis for opinion 
These financial statements are the responsibility of the Company’s management. Our responsibility is to express an 
opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with 
the  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. Our audits included performing procedures to assess the risks of material misstatement 
of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such 
procedures  included  examining,  on  a  test  basis,  evidence  supporting  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. We believe that our audits 
provide a reasonable basis for our opinion.

AAON, Inc. and Subsidiaries
Notes to Consolidated Financial Statements
December 31, 2017 

1.  Business Description

AAON, Inc. is a Nevada corporation which was incorporated on August 18, 1987. Our operating subsidiaries include 
AAON,  Inc.,  an  Oklahoma  corporation  and  AAON  Coil  Products,  Inc.,  a  Texas  corporation  (collectively,  the 
"Company"). The Consolidated Financial Statements include our accounts and the accounts of our subsidiaries.  

We  are  engaged  in  the  engineering,  manufacturing,  marketing  and  sale  of  air  conditioning  and  heating  equipment 
consisting of standard, semi-custom and custom rooftop units, chillers, packaged outdoor mechanical rooms, air handling 
units, makeup air units, energy recovery units, condensing units, geothermal/water-source heat pumps and coils.

 2.  Summary of Significant Accounting Policies

Principles of Consolidation

These financial statements are prepared in accordance with accounting principles generally accepted in the United 
States of America ("U.S. GAAP"). The accompanying consolidated financial statements include the accounts of the 
Company and its wholly-owned subsidiaries. All inter-company accounts and transactions have been eliminated.

Cash and Cash Equivalents

We consider all highly liquid temporary investments with original maturity dates of three months or less to be cash 
equivalents. Cash and cash equivalents consist of bank deposits and highly liquid, interest-bearing money market funds. 
The Company's cash and cash equivalents are held in a few financial institutions in amounts that exceed the insurance 
limits of the Federal Deposit Insurance Corporation. However, management believes that the Company's counterparty 
risks are minimal based on the reputation and history of the institutions selected.

Investments

Certificates of Deposit

We  held  $2.9  million  and  $5.5  million  in  certificates  of  deposit  at  December 31,  2017  and  December 31,  2016, 
respectively. At December 31, 2017, the certificates of deposit bear interest ranging from 0.95% to 1.10% per annum 
and have various maturities ranging from one to five months.

Investments Held to Maturity

At December 31, 2017, our investments held to maturity were comprised of $6.1 million of corporate notes and bonds 
with various maturities ranging from one to four months. The investments have moderate risk with S&P ratings ranging 
from AA+ to BBB.  

We record the amortized cost basis and accrued interest of the corporate notes and bonds in the Consolidated Balance 
Sheets. We record the interest and amortization of bond premium to interest income in the Consolidated Statements of 
Income.

The  following  summarizes  the  amortized  cost  and  estimated  fair  value  of  our  investments  held  to  maturity  at 
December 31, 2017 and December 31, 2016:

We evaluate these investments for other-than-temporary impairments on a quarterly basis. We do not believe there was 
an other-than-temporary impairment for our investments at December 31, 2017 or 2016.

Accounts and Note Receivable

Accounts and note receivable are stated at amounts due from customers, net of an allowance for doubtful accounts. We 
generally do not require that our customers provide collateral. The Company determines its allowance for doubtful 
accounts by considering a number of factors, including the credit risk of specific customers, the customer’s ability to 
pay current obligations, historical trends, economic and market conditions and the age of the receivable. Accounts are 
considered  past  due  when  the  balance  has  been  outstanding  for  ninety  days  past  negotiated  credit  terms. Past  due 
accounts are generally written-off against the allowance for doubtful accounts only after all collection attempts have 
been exhausted.

Concentration of Credit Risk

Our customers are concentrated primarily in the domestic commercial and industrial new construction and replacement 
markets. To date, our sales have been primarily to the domestic market, with foreign sales accounting for approximately 
4%, 4% and 4% of revenues for the years ended December 31, 2017, 2016 and 2015, respectively. One customer, Texas 
AirSystems, accounted for 10% or more of our sales during 2017, 2016 or 2015.  No customer accounted for 5% or 
more of our accounts receivable balance at December 31, 2017 or 2016.

Fair Value of Financial Instruments

The carrying amounts of cash and cash equivalents, receivables, accounts payable and accrued liabilities approximate 
fair value because of the short-term maturity of the items. The carrying amount of the Company's revolving line of 
credit, and other payables, approximate their fair values either due to their short term nature, the variable rates associated 
with the debt or based on current rates offered to the Company for debt with similar characteristics.

Inventories

Inventories are valued at the lower of cost or market using the first-in, first-out (“FIFO”) method. Cost in inventory 
includes purchased parts and materials, direct labor and applied manufacturing overhead. We establish an allowance 
for excess and obsolete inventories based on product line changes, the feasibility of substituting parts and the need for 
supply and replacement parts.

29

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Property, Plant and Equipment

Property,  plant  and  equipment,  including  significant  improvements,  are  recorded  at  cost,  net  of  accumulated 
depreciation. Repairs and maintenance and any gains or losses on disposition are included in operations.

Depreciation is computed using the straight-line method over the following estimated useful lives:

Buildings

Machinery and equipment

Furniture and fixtures

Impairment of Long-Lived Assets

3-40 years

3-15 years

3-7 years

We review long-lived assets for possible impairment when events or changes in circumstances indicate, in management’s 
judgment, that the carrying amount of an asset may not be recoverable. Recoverability is measured by a comparison 
of the carrying amount of an asset or asset group to its estimated undiscounted future cash flows expected to be generated 
by the asset or asset group. If the undiscounted cash flows are less than the carrying amount of the asset or asset group, 
an impairment loss is recognized for the amount by which the carrying amount of the asset or asset group exceeds its 
fair value.

Research and Development

The costs associated with research and development for the purpose of developing and improving new products are 
expensed as incurred. For the years ended December 31, 2017, 2016, and 2015 research and development costs amounted 
to approximately $13.0 million, $12.0 million, and $7.5 million, respectively.

Advertising

Advertising costs are expensed as incurred. Advertising expense for the years ended December 31, 2017, 2016, and 
2015 was approximately $1.7 million, $1.4 million, and $1.2 million, respectively.

Shipping and Handling

We incur shipping and handling costs in the distribution of products sold that are recorded in cost of sales. Shipping 
charges that are billed to the customer are recorded in revenues and as an expense in cost of sales. For the years ended 
December 31, 2017, 2016 and 2015 shipping and handling fees amounted to approximately $11.4 million, $10.3 million, 
and $9.6 million, respectively.

Income Taxes

Income taxes are accounted for under the asset and liability method. The Company recognizes deferred tax assets and 
liabilities for the expected future tax consequences of temporary differences between the book carrying amounts and 
the tax basis of assets and liabilities. Excess tax benefits and deficiencies are reported as an income tax benefit or 
expense on the statement of income and are treated as discrete items to the income tax provision in the reporting period 
in which they occur.  We establish accruals for unrecognized tax positions when it is more likely than not that our tax 
return positions may not be fully sustained. The Company records a valuation allowance for deferred tax assets when, 
in the opinion of management, it is more likely than not that deferred tax assets will not be realized.

30

Share-Based Compensation

The Company recognizes expense for its share-based compensation based on the fair value of the awards that are 
granted. The Company’s share-based compensation plans provide for the granting of stock options and restricted stock. 
The fair values of stock options are estimated at the date of grant using the Black-Scholes-Merton option valuation 
model. The use of the Black-Scholes-Merton option valuation model requires the input of subjective assumptions. 
Measured compensation cost is recognized ratably over the vesting period of the related share-based compensation 
award. Forfeitures are accounted for as they occur. The fair value of restricted stock awards is determined based on the 
market value of the Company’s shares on the grant date and the compensation expense is recognized on a straight-line 
basis during the service period of the respective grant.

Derivative Instruments

In the course of normal operations, the Company occasionally enters into contracts such as forward priced physical 
contracts  for  the  purchase  of  raw  materials  that  qualify  for  and  are  designated  as  normal  purchase  or  normal  sale 
contracts. Such contracts are exempted from the fair value accounting requirements and are accounted for at the time 
product is purchased or sold under the related contract. The Company does not engage in speculative transactions, nor 
does the Company hold or issue financial instruments for trading purposes.

Revenue Recognition

We recognize revenues from sales of products when title and risk of ownership pass to the customer. Final sales prices 
are fixed and based on purchase orders. Sales allowances and customer incentives are treated as reductions to sales and 
are provided for based on historical experiences and current estimates. Sales of our products are moderately seasonal 
with the peak period being July - November of each year.

In addition, the Company presents revenues net of sales tax and net of certain payments to our independent manufacturer 
representatives (“Representatives”). Representatives are national companies that are in the business of providing HVAC 
units and other related products and services to customers. The end user customer orders a bundled group of products 
and services from the Representative and expects the Representative to fulfill the order. Only after the specifications 
are agreed to by the Representative and the customer, and the decision is made to use an AAON HVAC unit, will we 
receive notice of the order. We establish the amount we must receive for our HVAC unit (“minimum sales price”), but 
do not control the total order price which is negotiated by the Representative with the end user customer.

We are responsible for billings and collections resulting from all sales transactions, including those initiated by our 
Representatives. The Representatives submit the total order price to us for invoicing and collection. The total order 
price  includes  our  minimum  sales  price  and  could  contain  an  additional  amount  which  may  include  both  the 
Representatives’ fee and amounts due for additional products and services required by the customer. These additional 
products and services may include controls purchased from another manufacturer to operate the unit, start-up services, 
and curbs for supporting the unit (“Third Party Products”). All are associated with the purchase of a HVAC unit but 
may be provided by the Representative or another third party. The Company is under no obligation related to Third 
Party Products.

The Representatives’ fee and Third Party Products amounts (“Due to Representatives”) are paid only after all amounts 
associated with the order are collected from the customer. The Due to Representatives amount is paid only after all 
amounts associated with the order are collected from the customer. The amount of payments to our representatives was 
$51.8  million,  $55.0  million,  and  $55.4  million  for  each  of  the  years  ended  December  31,  2017,  2016,  and  2015, 
respectively.

The Company also sells extended warranties on parts for various lengths of time ranging from six months to 10 years. 
Revenue for these separately priced warranties is deferred and recognized on a straight-line basis over the separately 
priced warranty period.

31

 
Insurance Reserves

Under the Company’s insurance programs, coverage is obtained for significant liability limits as well as those risks 
required to be insured by law or contract. It is the policy of the Company to self-insure a portion of certain expected 
losses related primarily to workers’ compensation and medical liability. Provisions for losses expected under these 
programs are recorded based on the Company’s estimates of the aggregate liabilities for the claims incurred.

Product Warranties

A provision is made for the estimated cost of maintaining product warranties to customers at the time the product is 
sold based upon historical claims experience by product line. The Company records a liability and an expense for 
estimated future warranty claims based upon historical experience and management's estimate of the level of future 
claims. Changes in the estimated amounts recognized in prior years are recorded as an adjustment to the liability and 
expense in the current year.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and 
assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities 
at  the  date  of  the  financial  statements  and  the  reported  amounts  of  revenues  and  expenses  during  the  reporting 
period. Because these estimates and assumptions require significant judgment, actual results could differ from those 
estimates  and  could  have  a  significant  impact  on  our  results  of  operations,  financial  position  and  cash  flows. We 
reevaluate  our  estimates  and  assumptions  as  needed,  but  at  a  minimum  on  a  quarterly  basis. The  most  significant 
estimates include, but are not limited to, the allowance for doubtful accounts, inventory reserves, warranty accrual, 
workers compensation accrual, medical insurance accrual, share-based compensation and income taxes. Actual results 
could differ materially from those estimates.

In connection with the closure of our Canadian facility on May 18, 2009, we sold land and a building in September 
2010 and assumed a note receivable from the borrower secured by the property. The C$1.1 million, 15 year note has 
an  interest  rate  of  4.0%  and  is  payable  to  us  monthly,  and  has  a  C$0.6  million  balloon  payment  due  in  October 
2025. Interest payments are recognized in interest income.

We evaluate the note for impairment on a quarterly basis. We determine the note receivable to be impaired if we are 
uncertain of its collectability based on the contractual terms. At December 31, 2017 and 2016, there was no impairment.

The Company has warranties with various terms from 18 months for parts to 25 years for certain heat exchangers. The 
Company has an obligation to replace parts or service its products if conditions under the warranty are met. A provision 
is made for estimated warranty costs at the time the related products are sold based upon the warranty period, historical 
trends, new products and any known identifiable warranty issues.  

Changes in the warranty accrual are as follows:

Our revolving credit facility provides for maximum borrowings of $30.0 million which is provided by BOKF, NA dba 
Bank of Oklahoma, formerly known as Bank of Oklahoma, N.A. ("Bank of Oklahoma"). Under the line of credit, there 
was one standby letter of credit totaling $0.8 million as of December 31, 2017. Borrowings available under the revolving 
credit facility at December 31, 2017, were $29.2 million. Interest on borrowings is payable monthly at LIBOR plus 
2.5%. No fees are associated with the unused portion of the committed amount. As of December 31, 2017 and 2016, 
we had no balance outstanding under our revolving credit facility. The revolving credit facility expires on July 27, 
2018.  At December 31, 2017 and 2016, the weighted average interest rate was 3.5% and 3.0%, respectively.

At December 31, 2017, we were in compliance with our financial covenants. These covenants require that we meet 
certain parameters related to our tangible net worth and total liabilities to tangible net worth ratio. At December 31, 
2017 our tangible net worth was $237.2 million, which meets the requirement of being at or above $125.0 million. Our 
total liabilities to tangible net worth ratio was 0.3 to 1.0, which meets the requirement of not being above 2 to 1.

The provision for income taxes differs from the amount computed by applying the statutory federal income tax rate 
before the provision for income taxes.

The reconciliation of the federal statutory income tax rate to the effective income tax rate is as follows:

The Tax Cuts and Jobs Act (the "Act") was enacted on December 22, 2017.  Major changes under the Act include the 
following:

•  Reducing the corporate rate to 21 percent
•  Doubling bonus depreciation to 100 percent for five years
Further limitations on executive compensation deductions
• 
•  Eliminating the domestic manufacturing deduction

As a result of these changes, the Company adjusted its deferred tax assets and liabilities existing at the date of enactment 
using the newly enacted rates for the periods when they are expected to be realized.    This remeasurement resulted in 
a benefit to income taxes of $4.4 million.  The new bonus depreciation provisions resulted in the Company taking $3.2 
million of bonus depreciation in the fourth quarter of 2017.  The Company sometimes has executive compensation that 
exceeds the $1.0 million limitation.  Typically the limit is exceeded due to the volume of stock activity performed by 
the executive during the year.  The Company cannot predict the performance of its stock or when executives may choose 
to  initiate  stock  activity.   As  such,  the  Company  is  unable  to  quantify  any  impact  of  this  tax  law  change  but  any 
compensation that does exceed this limitation in the future will be a permanent difference and cause an increase to our 
income tax provision.  The Company also has historically taken the domestic manufacturing deduction.  The Company 
will no longer receive the benefit of this deduction which typically has lowered our effective tax rate by 3.0% to 4.0%.

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and 
liabilities for financial reporting purposes and the amount used for income tax purposes.

We  file  income  tax  returns  in  the  U.S.,  state  and  foreign  income  tax  returns  jurisdictions. We  are  subject  to  U.S. 
examinations for tax years 2013 to present, and to non-U.S. income tax examinations for the tax years of 2013 to 
present. In  addition,  we  are  subject  to  state  and  local  income  tax  examinations  for  tax  years  2013  to  present. The 
Company continues to evaluate its need to file returns in various state jurisdictions. Any interest or penalties would be 
recognized as a component of income tax expense.

11.  Share-Based Compensation

On May 22, 2007, our stockholders adopted a Long-Term Incentive Plan ("LTIP") which provided an additional 3.3
million shares that could be granted in the form of stock options, stock appreciation rights, restricted stock awards, 
performance units and performance awards, in addition to the shares from the previous plan, the 1992 Plan. Since 
inception of the LTIP, non-qualified stock options and restricted stock awards have been granted with the same vesting 
schedule as the 1992 Plan. Under the LTIP, the exercise price of shares granted may not be less than 100% of the fair 
market value at the date of the grant.

On May 24, 2016, our stockholders adopted the 2016 Long-Term Incentive Plan ("2016 Plan") which provides for 
approximately  3.8  million  shares,  comprised  of  3.4  million  new  shares  provided  for  under  the  2016  Plan  and 
approximately 0.4 million shares that were available for issuance under the previous LTIP, that are now authorized for 
issuance under the 2016 Plan, that can be granted in the form of stock options, stock appreciation rights, restricted stock 
awards, performance awards, dividend equivalent rights, and other awards. Under the 2016 Plan, the exercise price of 
shares granted may not be less than 100% of the fair market value at the date of the grant. The 2016 Plan is administered 
by the Compensation Committee of the Board of Directors or such other committee of the Board of Directors as is 
designated by the Board of Directors (the "Committee"). Membership on the Committee is limited to independent 
directors. The Committee may delegate certain duties to one or more officers of the Company as provided in the 2016 
Plan. The Committee determines the persons to whom awards are to be made, determines the type, size and terms of 
awards, interprets the 2016 Plan, establishes and revises rules and regulations relating to the 2016 Plan and makes any 
other determinations that it believes necessary for the administration of the 2016 Plan.

The total pre-tax compensation cost related to unvested stock options not yet recognized as of December 31, 2017 is 
$8.3 million and is expected to be recognized over a weighted-average period of 2.29 years.

36

 
 
 
 
 
The following weighted average assumptions were used to determine the fair value of the stock options granted on the 
original grant date for expense recognition purposes for options granted during December 31, 2017, 2016 and 2015
using a Black Scholes-Merton Model:

Director and Officers:

Expected dividend yield

Expected volatility

Risk-free interest rate

Expected life (in years)

The  expected  term  of  the  options  is  based  on  evaluations  of  historical  and  expected  future  employee  exercise 
behavior. The  risk-free  interest  rate  is  based  on  the  U.S.  Treasury  rates  at  the  date  of  grant  with  maturity  dates 
approximately equal to the expected life at the grant date. Volatility is based on historical volatility of our stock over 
time periods equal to the expected life at grant date.

The total intrinsic value of options exercised during December 31, 2017, 2016 and 2015 was $4.5 million, $4.9 million
and $7.4 million, respectively. The cash received from options exercised during December 31, 2017, 2016 and 2015
was $2.3 million, $2.1 million and $2.8 million, respectively. The impact of these cash receipts is included in financing 
activities in the accompanying Consolidated Statements of Cash Flows.

Since 2007, as part of the LTIP and since May 2016 as part of the 2016 Plan, the Compensation Committee of the Board 
of Directors has authorized and issued restricted stock awards to directors and certain key employees. Restricted stock 
awards granted to directors vest one-third each year. All other restricted stock awards vest at a rate of 20% per year. The 
fair value of restricted stock awards is based on the fair market value of AAON common stock on the respective grant 
dates, reduced for the present value of dividends.

These awards are recorded at their fair value on the date of grant and compensation cost is recorded using straight-line 
vesting over the service period. At December 31, 2017, unrecognized compensation cost related to unvested restricted 
stock awards was approximately $6.5 million which is expected to be recognized over a weighted average period of 
1.85 years.

Defined Contribution Plan - 401(k) - We sponsor a defined contribution plan (the "Plan”). Eligible employees may 
make  contributions  in  accordance  with  the  Plan  and  IRS  guidelines.  In  addition  to  the  traditional  401(k),  eligible 
employees are given the option of making an after-tax contribution to a Roth 401(k) or a combination of both. The Plan 
provides for automatic enrollment and for an automatic increase to the deferral percentage at January 1st of each year 
and each year thereafter. Eligible employees are automatically enrolled in the Plan at a 6% deferral rate and currently 
contributing employees deferral rates will be increased to 6% unless their current rate is above 6% or the employee 
elects to decline the automatic enrollment or increase.

Effective October 1, 2013, the Plan was amended such that the Company contributed 3% of eligible payroll to the Plan 
for each employee and matched 100% up to 6% of employee contributions of eligible compensation. We contributed 
and continue to contribute in the form of cash and direct the investment to shares of AAON stock. Employees are 100%
vested in salary deferral contributions and vest 20% per year at the end of years two through six of employment in 
employer matching contributions. The additional 3% Company contribution, a Safe-Harbor contribution, vested over 
two years. 

39

 
 
 
 
Effective  January  1,  2016,  the  Plan  was  amended  such  that  the  Company  matches  175%  up  to  6%  of  employee 
contributions of eligible compensation. The Company no longer contributes 3% of eligible payroll to the Plan for each 
employee. The Company ceased paying administrative expenses for the Plan at which time administrative expenses 
are paid for by Plan participants. Additionally, Plan participant forfeitures are used to reduce the cost of the Company 
contributions. 

For the years ended December 31, 2017, 2016 and 2015 we made contributions of $6.1 million, $5.9 million and $9.0 
million, respectively. Administrative expenses were approximately $0, $40.0 thousand, and $0.1 million for the years 
ended 2017, 2016 and 2015, respectively.

Profit Sharing Bonus Plan - We maintain a discretionary profit sharing bonus plan under which approximately 10%
of pre-tax profit is paid to eligible employees on a quarterly basis in order to reward employee productivity. Eligible 
employees are regular full-time employees who are actively employed and working on the first and last days of the 
calendar quarter and who were employed full-time for at least three full months prior to the beginning of the calendar 
quarter. Profit sharing expense was $8.4 million, $9.0 million and  $8.0 million for the years ended December 31, 2017, 
2016 and 2015, respectively.

13.  Stockholders’ Equity

Stock Repurchase - The Board has authorized three stock repurchase programs for the Company. The Company may 
purchase shares on the open market from time to time, up to a total of 5.7 million shares. The Board must authorize 
the timing and amount of these purchases. Effective May 24, 2016, the Board authorized up to $25.0 million in open 
market repurchases and on June 2, 2016, the Company executed a repurchase agreement in accordance with the rules 
and regulations of the SEC allowing the Company to repurchase an aggregate amount of $25.0 million or a total of 
approximately 2.0 million shares from the open market. The repurchase agreement expired on April 15, 2017. The 
Company also has a stock repurchase arrangement by which employee-participants in our 401(k) savings and investment 
plan are entitled to have shares in AAON, Inc. stock in their accounts sold to the Company. The maximum number of 
shares to be repurchased is contingent upon the number of shares sold by employee-participants. Lastly, the Company 
repurchases  shares  of AAON,  Inc.  stock  from  certain  of  its  directors  and  employees  for  payment  of  statutory  tax 
withholdings on stock transactions. A11 other repurchases from directors or employees are contingent upon Board 
approval. All repurchases are done at current market prices.

We are subject to various claims and legal actions that arise in the ordinary course of business. We closely monitor 
these claims and legal actions and frequently consult with our legal counsel to determine whether they may, when 
resolved, have a material adverse effect on our financial position, results of operations or cash flows and we accrue 
and/or disclose loss contingencies as appropriate. We have concluded that the likelihood is remote that the ultimate 
resolution of any pending litigation or claims will be material or have a material adverse effect on the Company's 
business, financial position, results of operations or cash flows.

We are occasionally party to short-term, cancellable and occasionally non-cancellable, fixed price contracts with major 
suppliers for the purchase of raw material and component parts. We expect to receive delivery of raw materials for use 
in our manufacturing operations. These contracts are not accounted for as derivative instruments because they meet 
the normal purchase and normal sales exemption.

15. New Accounting Pronouncements

Changes to U.S. GAAP are established by the Financial Accounting Standards Board ("FASB") in the form of accounting 
standards updates ("ASUs") to the FASB's Accounting Standards Codification.

We consider the applicability and impact of all ASUs. ASUs not listed below were assessed and determined to be either 
not applicable or are expected to have minimal impact on our consolidated financial statements and notes thereto.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which requires an entity to 
recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to 
customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. 
In August 2015, with the issuance of ASU 2015-14, the FASB amended the effective date for us to January 1, 2018. 

The following ASUs have been issued in 2016 along with ASU 2014-09 with the same effective dates and transition 
requirements:

•  ASU 2016-08, Principal versus Agent Considerations (Reporting Revenue Gross versus Net), which provides 

implementation guidance for Topic 606 on principal versus agent considerations.

•  ASU  2016-10,  Identifying  Performance  Obligations  and  Licensing,  which  provides  clarification  for  two 
aspects of Topic 606: identifying performance obligations and the licensing implementation guidance.

•  ASU 2016-12, Revenue from Contracts with Customers, which further amends Topic 606. 
•  ASU 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers, 

which further amends Topic 606.

The Company plans to adopt using the retrospective transition method. The Company believes the impact will not be 
material to the consolidated financial statements.  The Company has reviewed all types of customer contracts and gone 
through the five step process outlined in ASU 2014-09 for each type of contract.  The new five step process required 
by ASU 2014-09 provides results substantially consistent with our current revenue recognition policies.  The Company 
has also evaluated the categories to use for the disaggregate revenue disclosures.  The primary change upon adoption 
will be additional disclosures to show disaggregated revenue and further details around our revenue recognition process.  
Once  we adopt ASU 2014-09, we do not anticipate that our internal control framework will materially change, but 
rather  that  existing  internal  controls  will  be  modified  and  augmented,  as  necessary,  to  consider  our  new  revenue 
recognition policy effective January 1, 2018.

41

In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial 
Liabilities, which will address certain aspects of recognition, measurement, presentation and disclosure of financial 
instruments. The ASU becomes effective in the annual reporting period beginning after December 31, 2017, including 
interim reporting periods. We do not expect ASU 2016-01 will have a material effect on our consolidated financial 
statements and notes thereto.

In May 2017, the FASB issued ASU 2017-09, Scope of Modification Accounting, which addresses changes to the terms 
or condition of a share-based payment award.  The ASU becomes effective in the annual reporting period beginning 
after December 15, 2017, including interim reporting periods. We do not expect ASU 2017-09 will have a material 
effect on our consolidated financial statements and notes thereto.

16. Earnings Per Share

Basic net income per share is calculated by dividing net income by the weighted average number of shares of common 
stock outstanding during the period. Diluted net income per share assumes the conversion of all potentially dilutive 
securities and is calculated by dividing net income by the sum of the weighted average number of shares of common 
stock outstanding plus all potentially dilutive securities. Dilutive common shares consist primarily of stock options and 
restricted stock awards.

The following table sets forth the computation of basic and diluted earnings per share:

Item 9.  Changes in and Disagreements with Accountants on Accounting and Financial Disclosure.

Not Applicable.

Item 9A.  Controls and Procedures.

(a)  Evaluation of Disclosure Controls and Procedures

At the end of the period covered by this Annual Report on Form 10-K, our management, under the supervision and 
with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of 
the design and operation of our disclosure controls and procedures. Based on that evaluation, our Chief Executive 
Officer and Chief Financial Officer believe that: 

•  Our  disclosure  controls  and  procedures  are  designed  at  a  reasonable  assurance  threshold  to  ensure  that 
information required to be disclosed by us in the reports we file under the Securities Exchange Act of 1934 
is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and 
forms; and

•  Our  disclosure  controls  and  procedures  operate  at  a  reasonable  assurance  threshold  such  that  important 
information flows to appropriate collection and disclosure points in a timely manner and are effective to ensure 
that such information is accumulated and communicated to our management, and made known to our Chief 
Executive Officer and Chief Financial Officer, particularly during the period when this Annual Report was 
prepared, as appropriate to allow timely decisions regarding the required disclosure.

Our Chief Executive Officer and Chief Financial Officer have evaluated our disclosure controls and procedures and 
concluded that these controls and procedures were effective as of December 31, 2017.

(b)  Management's Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over our financial reporting. 
Our internal control over financial reporting is a process designed by, or under the supervision of, our principal executive 
and principal financial officer, and effected by our board of directors, management and other personnel, to provide 
reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for 
external purposes in accordance with U.S. GAAP. 

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems 
determined to be effective can provide only reasonable assurance with respect to financial statement preparation and 
presentation. 

In making our assessment of internal control over financial reporting, management has used the criteria issued by the 
Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  ("COSO")  in  the  2013  Internal  Control—
Integrated Framework. Based on our assessment, we believe that, as of December 31, 2017, our internal control over 
financial reporting is effective at the reasonable assurance level based on those criteria. 

The effectiveness of the Company's internal control over financial reporting as of December 31, 2017 has been audited 
by Grant Thornton LLP, our independent registered public accounting firm, as stated in their report which is included 
in this Item 9A of this report on Form 10-K.

(c)  Changes in Internal Control over Financial Reporting

There have been no changes in internal control over financial reporting that occurred during the fourth quarter of 2017
that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders
AAON, Inc.

Opinion on internal control over financial reporting
We have audited the internal control over financial reporting of AAON, Inc. (a Nevada corporation) and subsidiaries 
(the “Company”) as of December 31, 2017, based on criteria established in the 2013 Internal Control—Integrated 
Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO").   In our 
opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of 
December 31, 2017, based on criteria established in the 2013 Internal Control - Integrated Framework issued by COSO.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States) ("PCAOB"), the consolidated financial statements of the Company as of and for the year ended December 
31, 2017, and our report dated February 27, 2018, expressed an unqualified opinion on those financial statements.

Basis for opinion
The Company’s management is responsible 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 Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion 
on the Company’s internal control over financial reporting based on our audit.  We are a public accounting firm registered 
with the 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and 
perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was 
maintained in all material respects. Our audit included obtaining an understanding of internal control over financial 
reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness 
of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the 
circumstances. We believe that our audit provides a reasonable basis for our opinion.

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.
