ITEM 1 — BUSINESS 

OVERVIEW 

PART I 

Energy Recovery, Inc. (the “Company”, “Energy Recovery”, “Our”, “Us”, and “We”) is an energy solutions provider to 
industrial fluid flow markets worldwide. We make industrial processes more operating and capital expenditure efficient. Our 
solutions  convert  wasted  pressure  energy  into  a  reusable  asset  and  preserve  or  eliminate  pumping  technology  in  hostile 
processing environments. Our solutions are marketed and sold in fluid flow markets, such as water, oil & gas and chemical 
processing, under the trademarks ERI®, PX®, Pressure Exchanger®, PX Pressure Exchanger®, AT™, AquaBold™, VorTeq™, 
IsoBoost®, and IsoGen®. Our solutions are developed in whole or in part, in the United States of America (“U.S.”), as well 
as other locations internationally. 

Energy Recovery was incorporated in Virginia in April 1992, reincorporated in Delaware in March 2001, and became a 
public company in July 2008. Our headquarters and primary manufacturing center is located at 1717 Doolittle Drive, San 
Leandro, California 94577, and we have four (4) wholly-owned subsidiaries: ERI Energy Recovery Holdings Ireland Limited; 
ERI Energy Recovery Ireland Ltd.; Energy Recovery Iberia, S.L.; and Energy Recovery Canada Corp. We also have sales 
offices in Dubai, United Arab Emirates and Shanghai, Peoples Republic of China. Our main telephone number is (510) 483-
7370. 

The Energy Recovery website is www.energyrecovery.com. We use the Investor Relations section of our website as a 
routine channel for distribution of important information, including news releases, presentations, and financial statements. 
Our Annual Report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, all amendments to those 
reports, and the Proxy Statement for our Annual Meeting of Stockholders are made available, free of charge, in the Investor 
Relations section of our website, as soon as reasonably practicable after the reports have been filed with or furnished to the 
Securities and Exchange Commission (“SEC”). The information contained on our website or any other website is not part of 
this report nor is it considered to be incorporated by reference herein or with any other filing we make with the SEC. 

FLUID FLOW MARKETS 

Our primary industrial fluid flow markets are water desalination and oil & gas. We have been and continue to be the 
technology  leader  for  energy  recovery  devices  (“ERDs”)  in  the  water  desalination  market  with  our  proprietary  Pressure 
Exchanger  technology  and  turbochargers.  We  also  provide  high-performance  and  high-efficiency  pumps  to  facilitate  a 
packaged solution for our customers. Building on our leading technology, we have expanded our solution offerings into other 
fluid flow markets, such as those found in upstream, midstream, and downstream applications of the oil & gas industry, as 
well as exploring other end markets for which our solutions may be applicable. We offer the VorTeq hydraulic fracturing 
system (“VorTeq”), IsoBoost, and IsoGen product lines to the oil & gas market. 

Water Desalination 

Water Desalination has been our core market for revenue generation to date. The water desalination market ranges from 
small water desalination plants such as those used in cruise ships and resorts to mega-project desalination plant deployments 
globally. Because of the geographical location of many significant desalination projects, geopolitical and economic events 
can have an effect on the timing of expected projects. In addition, population and economic growth in countries such as India 
and China are driving water demand for human, agricultural, and industrial use. We anticipate that markets traditionally not 
associated with water desalination, including the United States, will inevitably develop and provide further revenue growth 
opportunities. Our solutions leverage our Pressure Exchanger, turbocharger, and pump technologies providing our customers 
significant operational efficiency and energy savings. 

Oil & Gas 

Across the oil & gas upstream, midstream and downstream market, highly pressurized fluid flows are required to extract 

and process oil or gas. These pressurized fluid flows are both a necessity and liability to the oil & gas industry.  

Within the oil & gas upstream segment, hydraulic fracturing is a well-stimulation technique in which rock is fractured 
by pressurized liquid through the injection of a highly abrasive, proppant-laden fluid into a wellbore to create cracks in deep-
rock formations thereby permitting oil & gas extraction. Oilfield service providers utilize high-pressure hydraulic fracturing 

-4- 

  
  
  
  
  
  
  
  
  
  
  
  
 
pumps to pressurize the fracturing fluid at treating pressures up to 15,000 psi. These pumps are routinely destroyed during 
the  hydraulic  fracturing  process  causing  significant  oilfield  service  operator  costs  associated  with  excessive  downtime, 
repairs, maintenance, and capital equipment redundancy. Our solution leverages our Pressure Exchanger technology to isolate 
high-pressure hydraulic fracturing pumps from abrasive fracturing fluid thereby enabling oilfield service operators to realize 
immediate and long-term savings. 

Within the oil & gas midstream and downstream segments, pressure energy becomes a waste product at different stages 
of oil and gas processing. It is at these stages that our technology enables the recovery of pressure energy in the fluid flow 
either through the exchange of pressure within the application or by converting it to electricity. We enable gas processing 
plant and pipeline owners and operators to achieve immediate and long-term energy savings with little or no operational 
disruption.

OUR SOLUTIONS 

In the Water Desalination market, our energy recovery solutions reduce plant operating costs by capturing and reusing 
the otherwise lost pressure energy from the reject stream of the desalination process. In the Oil & Gas market, our hydraulic 
fracturing solutions reduce operating and capital equipment costs by isolating high cost pumping equipment from highly 
abrasive fracturing fluids. In addition, our oil & gas solutions reduce plant or pipeline operating costs by capturing and reusing 
otherwise lost pressure energy. Energy and capital costs are major cost drivers in both the water desalination and oil & gas 
markets. 

Water Desalination 

Our water desalination ERDs are categorized into two technology groups: PX energy recovery devices and turbochargers. 
The first technology group is comprised of our patented Pressure Exchanger technology consisting of ceramic rotors and 
almost  frictionless  hydrodynamic  bearings.  Our  PX  energy  recovery  devices  perform  with  up  to  98%  efficiency  and 
unmatched uptime in the desalination industry as well as save up to 60% of the energy costs of a desalination plant. 

The second technology group is comprised of AT turbochargers designed for low-pressure brackish and high-pressure 
seawater  reverse  osmosis  systems.  Our  turbochargers  provide  premium  efficiency  with  state-of-the-art  engineering  and 
configuration. Designed for reliability and optimum efficiency, our turbochargers offer substantial savings, and the custom-

designed hydraulics and 3-D geometry allow for optimum performance. Also, the patent-protected technology for volute 
inserts allows field flexibility. 

Complementing both our PX energy recovery devices and AT turbochargers are our high-efficiency and high-pressure 
pumps marketed under the trademark of AquaBold. These pumps range from single and multiple stage centrifugal pumps to 
circulation and advanced high-speed pumps. 

Oil & Gas  

In the Oil & Gas market, we design and manufacture innovative solutions that preserve or eliminate pumping technology 
in  hostile  processing  environments  and  convert  wasted  pressure  energy  into  a  reusable  asset.  Our  core  solutions  are  the 
VorTeq hydraulic fracturing system and our centrifugal line of products, the IsoBoost and the IsoGen. 

Field trials were initiated for the VorTeq in the second quarter of 2015 and successfully completed in the fourth quarter 
of  2015.  In  October  2015,  we  entered  into  a  fifteen  (15)  year  license  agreement  with  Schlumberger  for  the  exclusive, 
worldwide right to use the VorTeq technology for hydraulic fracturing onshore operations. The product is currently in the 
research and development stage. The VorTeq is an enabling technology for oilfield service (“OFS”) companies to isolate and 
preserve  costly  hydraulic  fracturing  pumps  by  re-routing  hostile  fracturing  fluid  away  from  these  critical  pumps.  These 
hydraulic fracturing pumps will then process only water, which leads to reduced repairs and maintenance costs, increased 
fleet revenue, and reduced capital costs by extending pump life expectancy and eliminating redundant capital equipment. The 
VorTeq further allows for the migration to increasingly efficient pumping technology that could lead to the revolutionizing 
of the hydraulic fracturing system.  

The  IsoBoost  and  IsoGen  were  commercialized  in  2012.  Our  IsoBoost  energy  recovery  systems  are  comprised  of 
hydraulic  turbo  chargers  and  related  controls  and  automation  systems.  Our  IsoBoost  systems,  through  the  use  of 
turbochargers, enable oil & gas operators to capture wasted hydraulic pressure energy from a high-pressure fluid flow and 
transfer the energy to a low-pressure fluid flow thereby recovering wasted pressure energy. Our IsoGen energy recovery 
systems are comprised of hydraulic turbines, generators, and related controls and automation systems. The IsoGen enables 
oil & gas operators to capture hydraulic energy and generate electricity from high-pressure fluid flows. Additionally, our 
energy recovery and power generation systems result in lower capital costs for oil & gas operators by minimizing the need 
for high-pressure pumps that consume large amounts of energy.  

Services 

We provide a portfolio of services tailored to our customers’ needs. Specifically, we assist our customers in the early 
stages of planning and design by leveraging our broad experience in fluid flows and advanced material science. We also 
provide engineering, technical support, and training to customers during installation and commissioning. Additionally, we 
offer preventive maintenance and support services as well as reinstallation services. To date the revenue from these services 
has not represented a significant portion of our revenue. 

CUSTOMERS 

Water Desalination 

Our water desalination customers include major international engineering, procurement, and construction (“EPC”) firms 
that design and build large desalination plants, original equipment manufacturers (“OEM”), which are companies that supply 
equipment and packaged solutions for small- to medium-sized desalination plants, and national, state and local municipalities 
worldwide.  

Large Engineering, Procurement and Construction Firms 

A significant portion of our revenue historically has come from sales of solutions to large EPC firms worldwide that 
have the required desalination expertise to engineer, undertake procurement for, construct, and sometimes own and operate 
large desalination plants or mega-projects (“MPD”). We work with these firms to specify our solutions for their plants. The 
time between project tender and shipment can range from 16 to 36 months. Each MPD project typically represents a revenue 
opportunity of between $1 million and $10 million. 

-6- 

  
   
  
  
  
  
  
  
  
  
  
  
  
  
A  limited  number  of  these  EPC  firms  account  for  10%  or  more  of  our  product  revenue.  Revenue  from  customers 
representing 10% or more of product revenue varies from year to year. For the year ended December 31, 2015, one customer, 
Acciona Agua, S.A.U., accounted for approximately 14% of our product revenue. For the year ended December 31, 2014, 
one customer, IDE Americas, Inc., accounted for approximately 14% of our product revenue. For the year ended December 
31, 2013, one customer, Acciona Agua, S.A.U., accounted for approximately 15% of our product revenue.  

Original Equipment Manufacturers 

We also sell our solutions and services to suppliers of pumps and other water-related equipment for assembly and use in 
small-  to  medium-sized  desalination  plants  located  in  hotels,  power  plants,  cruise  ships,  farm  operations,  island  bottlers, 
mobile and containerized water desalination solutions, and small municipalities. These OEMs also purchase our solutions for 
“quick  water”  or  emergency  water  solutions.  Our  OEM  customer  base  accounted  for  approximately  45%  of  our  2015 
revenues. We typically sell and promote our packaged solutions to this sales channel represented by a product mix of PX 
Pressure Exchangers, turbochargers, high-pressure pumps, and circulation “booster” pumps. The time from project tender 
and shipment can range from one (1) to twelve (12) months. OEM projects typically represent revenue opportunities between 
$0.01 million to $1.0 million.  

Oil & Gas 

Our oil & gas customers include international oil companies (“IOC”), national oil companies (“NOC”), exploration and 
production  companies  (“E&P”),  oilfield  service  companies  (“OFS”),  and  EPC  firms  that  design  and  build  oil  &  gas 
processing plants.  

Upstream 

OFS companies provide the infrastructure, equipment, intellectual property, and services needed by the oil & gas industry 
to explore for, extract, and transport crude oil and natural gas. OFS hydraulic fracturing operators face significant pressure 
to reduce costs as oil & gas companies curtail capital expenditures and seek operational efficiencies in response to lower 
commodity prices. We developed the VorTeq hydraulic pumping system which enables these operators to isolate pumps from 
fracturing fluid thereby reducing operating and capital costs. 

In the third quarter of 2014, we entered into a strategic partnership with Liberty Oil Field Services to pilot and conduct 
field trials with the VorTeq hydraulic pumping system, which were initiated in the second quarter of 2015. These field trials 
were successfully completed in December 2015. In October 2015, we entered into a fifteen (15) year license agreement with 
Schlumberger for the exclusive, worldwide right to use our VorTeq technology for hydraulic fracturing onshore operations.  

Midstream and Downstream 

With respect to IsoBoost and IsoGen, we have contracted and delivered oil & gas solutions, as pilot projects to customers 
in  North  America,  Asia,  and  the  Middle  East.  The  sales  cycle  for  our  oil  &  gas  solutions  can  be  prolonged  and  may  be 
impacted by procurement processes and budgetary constraints.  

For the year ended December 31, 2015, we recognized oil & gas revenue from the license agreement with Schlumberger, 
cancellation of a purchase order with Conoco Philips, and from the commissioning of an IsoGen system with a customer in 
Saudi Arabia. For the year ended December 31, 2014, we recognized oil & gas rental income from the operating lease and 
subsequent lease buy-out of an IsoGen system to a customer in Saudi Arabia. For the year ended December 31, 2013, we did 
not recognize any revenue from shipments of our oil & gas solutions.  

Additional information regarding our product revenue by segment is included in Note 13 to the Consolidated Financial 

Statements in this Form 10-K. 

COMPETITION 

Water Desalination 

The market for energy recovery devices and pumps in the Water Desalination market is competitive. As the demand for 

fresh water increases and the market expands, we expect competition to persist and intensify. 

-7- 

   
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
We  have  two  main  competitors  for  our  energy  recovery  devices:  Flowserve  Corporation  (Flowserve)  and  Fluid 
Equipment Development Company (FEDCO). We compete with these companies on the basis of price, quality, efficiency, 
lead time, expected life, downtime, and maintenance costs. Although these companies may offer competing solutions at lower 
prices, we believe that our solutions offer a competitive advantage because it is our belief that our solutions are the most cost-
effective energy recovery devices for reverse osmosis desalination over time. 

In the market for large desalination projects, our PX devices and large turbochargers compete primarily with Flowserve’s 
DWEER product. We believe that our PX devices have a competitive advantage over DWEER devices because our devices 
are made with highly durable and corrosion-resistant ceramic parts that are designed for a life of 25 years, are warranted for 
high efficiencies, cause no unplanned downtime, and offer lower lifecycle costs. Additionally, the PX devices offer optimum 
scalability with a quick startup as well as minimal maintenance. We believe that our large turbocharger solutions also have a 
competitive advantage over the DWEER product, particularly in countries where energy costs are low and upfront capital 
costs are a critical factor in purchase decisions, because our turbocharger solutions have lower upfront capital costs, a simple 
design with one rotating assembly, a small physical footprint, and a long operating life that leads to low total lifecycle costs. 

In the market for small- to medium-sized desalination plants, our solutions compete with Flowserve’s Pelton turbines 
and FEDCO’s turbochargers. We believe that our PX devices have a competitive advantage over these solutions because our 
devices provide up to 98% energy efficiency, have lower lifecycle maintenance costs, and are made of highly durable and 
corrosion-resistant ceramic parts. We also believe that our turbochargers compete favorably with Pelton turbines and FEDCO 
turbochargers  on  the  basis  of  efficiency  and  price  and  because  our  turbochargers  have  design  advantages  that  enhance 
efficiency, field flexibility, and serviceability. 

In the market for high-pressure pumps, our solutions compete with pumps manufactured by Clyde Union Ltd.; FEDCO; 
Flowserve; Düchting Pumpen Maschinenfabrik GmbH & Co KG; KSB Aktiengesellschaft; Torishima Pump Mfg. Co., Ltd.; 
Sulzer Pumps, Ltd.; and other companies. We believe that our pump solutions are competitive with these solutions because 
our pumps are developed specifically for reverse osmosis desalination, are highly efficient, and feature product-lubricated 
bearings. 

Oil & Gas  

The market for our technology in the Oil & Gas market is competitive. As demand for our products increase, we expect 

competition to intensify. 

Within  the  oil  &  gas  upstream  market,  OFS  hydraulic  fracturing  operators  utilize  high-pressure  hydraulic  fracturing 
pumps to pressurize fracturing fluid. This fluid is sent through traditional missile manifolds into the wellbore to create cracks 
in the deep-rock formations thereby permitting oil & gas extraction. Our VorTeq system is a hydraulic pumping system that 
replaces the traditional missile manifold used by OFS hydraulic fracturing operators. There are many manufacturers of the 
traditional missile manifolds. 

We  believe  our  VorTeq  technology  represents  a  competitive  advantage  over  existing  missile  manifold  technology 
because our solution re-routes abrasive proppant away from high-pressure pumps, thereby extending pump lifespan, reducing 
repairs and maintenance costs, and decreasing the need for redundant capital equipment. In addition, because our VorTeq 
technology isolates the high-pressure pumps from abrasive proppant, OFS hydraulic fracturing operators have the ability to 
transition to more robust, longer lived centrifugal pumps thereby further decreasing operating and capital costs.  

Within the oil and gas midstream and downstream markets, acid gas removal — also known as amine gas treating — 
refers to a process that utilizes solvents such as an amine solution to remove acid gasses, specifically hydrogen sulfide (H2S) 
and  carbon  dioxide  (CO2)  from  natural  gas,  synthesis  gas,  or  other  hydrocarbon  streams.  Our  IsoBoost  and  IsoGen 
technologies integrate into acid gas removal systems to reduce energy consumption and increase the reliability and uptime 
of the amine circulation system. Currently, most acid gas removal plants use pumps and valves to pressurize and depressurize 
the amine solution; the depressurization of the cleansing fluid (e.g. amine) provides an opportunity for the use of energy 
recovery devices.  

Our IsoBoost system is based partly on hydraulic turbocharger technology. While to our knowledge the only turbocharger 
systems  presently  utilized  in  acid  gas  removal  applications  are  manufactured  by  Energy  Recovery,  there  is  at  least  one 
established competitor, FEDCO, which makes a similar hydraulic turbocharger for desalination applications. We combine 
our highly competitive turbocharger technology with process equipment and control systems to make a unique, proprietary, 
and highly competitive offering for oil & gas and petrochemical plants.

Our IsoGen system is partly based on hydraulic turbine technology which converts recovered energy to electric power. 
Many other companies make hydraulic turbines for a broad range of applications. For acid gas removal plants, our competitors 
utilize reverse running pumps (also called hydraulic power recovery turbines or HPRTs) to perform the same energy recovery 
function that our IsoGen systems provide. These reverse running pumps are typically part of a large “skid-mounted” system, 
incorporating  a  multi-stage  pump  and  motor,  all  rotating  about  a  common  shaft.  Flowserve,  Sulzer,  and  Shin  Nippon 
Machinery  are  known  to  have  supplied  these  systems  and  other  major  pump  companies  may  have  built  systems  for  this 
application as well. We believe most of our competitors’ reverse running pump systems present concerns related to reliability, 
operational flexibility, and low energy efficiency as compared to our solution. 

Sales and Marketing 

We market and sell our solutions directly to customers through our direct sales organization and, in some countries, 
through authorized, independent sales agents. Our current sales organization consists of two groups, water desalination and 
oil  &  gas.  The  water  desalination  group  targets  MPD,  OEM,  and  aftermarket  opportunities.  MPD  opportunities  are  for 
desalination projects exceeding 50,000 cubic meters per day. OEM opportunities include sales of PX devices, turbochargers, 
and pumps for plants typically designed to produce less than 50,000 cubic meters per day. Aftermarket opportunities include 
new and replacement parts and products, as well as technical support, training, product installation, and plant commissioning.  

Our oil & gas group targets IOCs, NOCs, E&Ps, OFSs, or EPCs on behalf of oil producers, and chemical producers who 

have applications for our solutions and services. 

Many of the large EPC firms that specialize in large projects are located in the Mediterranean region. Our sales branch 
in Dubai, United Arab Emirates serves the Middle East, where many desalination plants and key EPC firms are located. We 
have a sales force in Spain focused on the Spain and European markets. We also have a sales office in Shanghai, China to 
address  this  emerging  market  for  our  energy  recovery  solutions.  In  the  U.S.,  our  sales  office  along  with  our  corporate 
headquarters is located in San Leandro, California. In February 2016, we hired an oil & gas sales manager in Dublin, Ireland 
with responsibilities for Europe, the Middle East, and Africa. As opportunities and diversification dictate, particularly in oil 
& gas, we will look to expand our geographical presence. 

A significant portion of our revenue is from outside of the United States. Sales in the United States represented 7%, 4%, 
and 13% of our product revenue for the fiscal years 2015, 2014, and 2013, respectively. Additional segment and geographical 
information regarding our product revenue is included in Note 13 to the Consolidated Financial Statements in this Form  
10-K.  

Manufacturing 

Our  primary  manufacturing  facility  is  in  San  Leandro,  California,  where  our  energy  recovery  devices  are  produced, 
assembled, and tested. We produce the majority of our ceramic components for our water desalination PX solutions in our 
ceramics manufacturing facility in San Leandro. We complete machining and assemble of all ceramic components for our 
PX devices and many components of our turbochargers and pumps to protect the proprietary nature of our manufacturing 
methods and product designs and to maintain premium quality standards. In October 2015, we hired a supply chain manager 
in Dublin, Ireland responsible for commercializing the VorTeq and expanding our manufacturing activities in Europe.  

Research and Development 

Design, quality, and innovation are key facets of our corporate culture. Our development efforts are focused on enhancing 
our existing energy recovery devices and pumps for the desalination market and advancing our know-how in fluid dynamics 
for use in other markets such as oil & gas and chemical processing. In the last several years our engineering work has led to 
the  development  of  new  solutions  for  applications  both  within  the  water  desalination  market  as  well  as  other  fluid  flow 
applications such as oil & gas and chemical processing.  

In July 2015, with the sale of our oil & gas intellectual property (“IP”) to ERI Energy Recovery Holdings Ireland Limited, 

Dublin, Ireland has become key to our VorTeq commercialization efforts. 

We continue to make significant investments in oil & gas technologies and solutions to diversify our business and expand 
addressable markets. Most of these investments are expensed as incurred in research and development expense. Those that 
have  reached  commercial  feasibility  are  ultimately  recorded  in  cost  of  revenue  when  leased,  sold,  or  evaluated  for  net 
realizable value and therefore impact gross profit. Research and development expense totaled $7.7 million, $9.7 million, and 
$4.4 million in 2015, 2014, and 2013, respectively. Research and development costs may increase in the future as we continue 

-9- 

   
  
  
  
  
  
  
  
  
  
  
to advance our existing technology and develop new energy recovery and efficiency-enhancing solutions for markets outside 
of seawater desalination. 

Seasonality 

In the water desalination sector, we often experience substantial fluctuations in product revenue from quarter to quarter 
and from year to year due to the fact that a single order for our energy recovery devices by a large EPC firm for a particular 
plant may represent significant revenue. In addition, historically our EPC customers tend to order a significant amount of 
equipment for delivery in the fourth quarter, and as a consequence, a significant portion of our annual sales typically occurs 
during the fourth quarter. 

We do not currently have enough history to determine revenue patterns within the oil & gas sector. 

Intellectual Property 

We seek patent protection for new technologies, inventions, and improvements that are likely to be incorporated into our 
solutions. We rely on patents, trade secret laws, and contractual safeguards to protect the proprietary tooling, processing 
techniques, and other know-how used in the production of our solutions. We have a robust intellectual property portfolio 
consisting  of  (i)  U.S.  and  internationally  issued  patents  and  (ii)  a  number  of  U.S.  and  International  pending  patent 
applications.  

We have registered the following trademarks with the United States Patent and Trademark office: “ERI,” “PX,” “PX 
Pressure Exchanger,” “Pressure Exchanger,” the Energy Recovery logo, “ERI Energy Recovery, Inc.”, “Making Desalination 
Affordable”, “AT”, “VorTeq”, “IsoBoost”, and “IsoGen”. We have also applied for and received registrations in international 
trademark offices.  

In  July  2015,  the  U.S.  parent  company  transferred  the  oil  &  gas  IP  via  platform  license  agreements  to  ERI  Energy 

Recovery Holdings Ireland Limited. 

Employees  

As of December 31, 2015, we had 114 employees: 42 in manufacturing; 27 in corporate services and management; 28 
in sales, service, and marketing; and 17 in engineering and research and development. Thirteen (13) of these employees were 
located outside of the United States. We also engage a relatively small number of independent contractors, primarily as sales 
agents worldwide. We have not experienced any work stoppages, and our employees are not unionized.

Item 1A — Risk Factors 

This Annual Report on Form 10-K contains forward-looking statements that involve risks and uncertainties. Our actual results 
could differ materially from those anticipated by such forward-looking statements as a result of various factors, including 
those set forth below. 

●  We depend on the construction of new desalination plants for revenue, and as a result, our operating results have 
experienced, and may continue to experience, significant variability due to volatility in capital spending, availability
of project financing, and other factors affecting the water desalination industry. 

We  currently  derive  the  majority  of  our  revenue  from  sales  of  products  and  services  used  in  desalination  plants  for 
municipalities,  hotels,  mobile  containerized  desalination  solutions,  resorts,  and  agricultural  operations  in  dry  or  drought-
ridden regions of the world. The demand for our products may decrease if the construction of desalination plants declines for 
political, economic, or other factors, especially in these regions. Other factors that could affect the number and capacity of 
desalination  plants  built  or  the  timing  of  their  completion  include  the  availability  of  required  engineering  and  design 
resources; a weak global economy; shortage in the supply of credit and other forms of financing; changes in government 
regulation, permitting requirements, or priorities; and reduced capital spending for desalination. Each of these factors could 
result in reduced or uneven demand for our products. Pronounced variability or delays in the construction of desalination 
plants or reductions in spending for desalination could negatively impact our sales and revenue and make it difficult for us 
to accurately forecast our future sales and revenue, which could lead to increased inventory and use of working capital. 

●  We face competition from a number of companies that offer competing energy recovery and pump solutions. If any 
one of these companies produces superior technology or offers more cost-effective products, our competitive position
in the market could be harmed and our profits may decline. 

The  market  for  energy  recovery  devices  and  pumps  for  desalination  plants  is  competitive  and  evolving.  We  expect 
competition, especially competition on price, to persist and intensify as the desalination market grows and new competitors 
enter the market. Some of our current and potential competitors may have significantly greater financial, technical, marketing, 
and other resources; longer operating histories; or greater name recognition. They may also have more extensive products 
and product lines that would enable them to offer multi-product or packaged solutions as well as competing products at lower 
prices or with other more favorable terms and conditions. As a result, our ability to sustain our market share may be adversely 
impacted, which would affect our business, operating results, and financial condition. In addition, if one of our competitors 
were to merge or partner with another company, the change in the competitive landscape could adversely affect our continuing 
ability to compete effectively. 

●  Global oil price deflation may result in the delay or cancellation of projects by oil & gas customers thus negatively

affecting the rate of our market penetration and consequently revenue. 

The continued deflationary oil environment may delay and even stall adoption and deployment of our products including but 
not limited to the VorTeq® as licensed by Schlumberger. Additionally, there is a historical correlation between a strong U.S. 
dollar and declining oil prices. Emerging market economies, those dependent on commodity exports, and especially those 
for whom oil exports make up a significant percent of total exports, may be unable to retrofit or expand their oil exploration, 
production,  and  gas  processing  infrastructure  thus  negatively  impacting  our  addressable  market  and  future  revenue. 
Additionally, oil price deflation may lead to widespread bankruptcies and defaults by exploration, production, and processing 
customers which may further negatively affect our addressable markets and financial performance. 

●  Part of our inventory may become excess or obsolete, which would increase our cost of revenues.  

Inventory of raw materials, parts, components, work in-process, or finished products may accumulate, and we may encounter 
losses due to a variety of factors, including: 

• 

• 

• 

technological change in the desalination and oil & gas industries that result in product changes; 

long delays in shipment of our products or order cancellations;  

our need to order raw materials that have long lead times and our inability to estimate exact amounts and types of 
items thus needed, especially with regard to the configuration of our high-efficiency pumps; and 

-11- 

  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
• 

cost reduction initiatives resulting in component changes within the products. 

In addition, we may from time to time purchase more inventory than is immediately required in order to shorten our delivery 
time in case of an increase in demand for our products. If we are unable to forecast demand for our products with a reasonable 
degree  of  certainty  and  our  actual  orders  from  our  customers  are  lower  than  these  forecasts,  we  may  accumulate  excess 
inventory  that we  may  be  required  to  write  off,  and  our  business,  financial  condition, and results  of operations  could  be 
adversely affected.  

●  Our operating results may fluctuate significantly, making our future operating results difficult to predict and causing

our operating results to fall below expectations or guidance. 

Our operating results may fluctuate due to a variety of factors, many of which are outside of our control. Since a single order 
for our energy recovery devices may represent substantial revenue, we have experienced significant fluctuations in revenue 
from quarter to quarter and year to year, and we expect such fluctuations to continue. As a result, comparing our operating 
results on a period-to-period basis may not be meaningful. Our past results are not necessarily an indication of our future 
performance. If our revenue or operating results fall below the expectations of investors or securities analysts or below any 
guidance we may provide to the market, the price of our common stock would likely decline. 

In 2015 and in past years, customer buying patterns led to a significant portion of our sales occurring in the fourth quarter. 
This presents the risk that delays, cancellations, or other adverse events in the fourth quarter could have a substantial negative 
impact on annual results. Our results have fluctuated due to adverse timing of larger orders during the year, the effects of a 
global  decline  in  new  desalination  plant  construction  stemming  from  global  economic  and  financial  pressures,  and 
competition. Since it is difficult for us to anticipate our future results, our stock price may be adversely affected by the risks 
discussed in this paragraph. 

● 

If we are unable to collect unbilled receivables, which are caused in part by holdback provisions, our operating results
could be adversely affected. 

Our  contracts  with  large  engineering,  procurement,  and  construction  firms  generally  contain  holdback  provisions  that 
typically delay final installment payments by up to 30 months, after the product has been shipped and revenue has been 
recognized. Typically, between 5% and 15%, of the revenue we recognize pursuant to our customer contracts is subject to 
such holdback provisions and is accounted for as unbilled receivables. Such holdbacks can result in relatively high unbilled 
receivables.  If  we  are  unable  to  collect  these  performance  holdbacks  then  our  results  of  operations  would  be  adversely 
affected. 

●  Our future success depends on our ability to diversify into new markets outside of reverse osmosis water desalination

while continuing to market, enhance, and scale existing desalination products.  

We believe that developing new products for applications outside of desalination is a necessary strategy to accelerate future 
growth in our business as we continue to market, enhance, and scale existing desalination products.  

While new or enhanced products and services have the potential to meet specified needs of new or existing markets, pricing 
may not meet customer expectations, and our products may not compete favorably with products and services of current or 
potential  competitors.  New  products  may  be  delayed  or  cancelled  if  they  do  not  meet  specifications,  performance 
requirements, or quality standards, or perform as expected in a production environment. Product designs also may not scale 
as  expected.  We  may  have  difficulty  finding  new  markets  for  our  existing  technologies  or  developing  or  acquiring  new 
products  for  new  markets.  Customers  may  not  accept  or  be  slow  to  adopt  new  products  and  services,  and  potential  new 
markets may be too costly to penetrate. In addition, we may not be able to offer our products and services that meet customer 
expectations without decreasing our prices and eroding our margins. We may also have difficulty executing plans to break 
into  new  markets,  expanding  our  operations  to  successfully  manufacture  new  products,  or  scaling  our  operations  to 
accommodate increased business. If we are unable to develop competitive new products, open new markets, and scale our 
business to support increased sales and new markets, our business and results of operations will be adversely affected. 

We have hired and promoted individuals to new executive positions and undertaken other activities to pursue new markets 
beyond desalination. We may incur significant personnel and development expenses in these efforts without assurance as to 
when or if new products will contribute to revenue or be profitable.

●  Our diversification into new fluid flow markets such as oil & gas may not materialize according to our expectations. 

We have made a substantial investment in research, development, and sales to execute on our diversification strategy into 
fluid flow markets such as oil & gas and chemical processing. While we see diversification as core to our growth strategy, 
there is no guarantee that we will be successful in our efforts. Our model for growth is based on our ability to initiate and 
embrace disruptive technology trends, to enter new markets, both in terms of geographies and product areas, and to drive 
broad adoption of the products and services that we develop and market. While we believe that our products will, for example, 
enable gas processing plant operators to operate at a high level of energy efficiency with minimal downtime, we may be 
subject to claims if customers of these offerings experience significant downtimes or failures for which our warranty reserves 
may be inadequate given the lack of historical failure rates associated with new product introductions. We also could be 
subject to damage claims based on our products against which we may not be able to properly insure. In addition, profitability, 
if any, in new industrial verticals may be lower than in our desalination market, and we may not be sufficiently successful in 
our diversification efforts to recoup investments. If any of these were to occur, it could damage our reputation, limit our 
growth, and negatively affect our operating results. 

●  Our sales cycles can be long and unpredictable, and our sales efforts require considerable time and expense. As a
result, our sales are difficult to  predict and may vary substantially  from quarter to quarter, which may cause our
operating results to fluctuate. 

Our sales efforts involve substantial education of our current and prospective customers about the use and benefits of our 
energy  recovery  products.  This  education  process  can  be  time-consuming  and  typically  involves  a  significant  product 
evaluation process which is especially so when dealing with product introduction into new fluid flow industrial verticals. In 
desalination, the sales cycle for our OEM customers, which are involved with smaller desalination plants, averages one to 
twelve months. The sales cycle for our international engineering, procurement, and construction firm customers, which are 
involved with larger desalination plants, ranges from 16 to 36 months. In the oil & gas and chemical processing segments 
our  experience  indicates  that  sales  efforts  are  prolonged  due  in  part  to  customers’  reluctance  to  accept  new  technology, 
procurement  processes,  and  budgetary  constraints.  These  long  sales  cycles  make  quarter-by-quarter  revenue  predictions 
difficult and results in our expending significant resources well in advance of orders for our products. 

●  We depend on a limited number of suppliers for some of our components. If our suppliers are not able to meet our

demand and/or requirements, our business could be harmed. 

We rely on a limited number of suppliers for vessel housings, stainless steel ports, alumina powder, and tungsten carbide for 
our portfolio of PX devices and stainless steel castings and components for our turbochargers and pumps. Our reliance on a 
limited  number  of  manufacturers  for  these  supplies  involves  a  number  of  risks,  including  reduced  control  over  delivery 
schedules, quality assurance, manufacturing yields, production costs, and lack of guaranteed production capacity or product 
supply. We do not have long-term supply agreements with these suppliers but secure these supplies on a purchase order basis. 
Our suppliers have no obligation to supply products to us for any specific period, in any specific quantity, or at any specific 
price, except as set forth in a particular purchase order. Our requirements may represent a small portion of the total production 
capacities  of  these  suppliers,  and  our  suppliers  may  reallocate  capacity  to  other  customers,  even  during  periods  of  high 
demand for our products. We have in the past experienced, and may in the future experience, product quality issues and 
delivery delays with our suppliers due to factors such as high industry demand or the inability of our vendors to consistently 
meet our quality or delivery requirements. If our suppliers were to cancel or materially change their commitments to us or 
fail to meet quality or delivery requirements needed to satisfy customer orders for our products, we could lose time-sensitive 
customer orders, be unable to develop or sell our products cost-effectively or on a timely basis, if at all, and have significantly 
decreased revenue, which could harm our business, operating results, and financial condition. We may qualify additional 
suppliers in the future, which would require time and resources. If we do not qualify additional suppliers, we may be exposed 
to increased risk of capacity shortages due to our dependence on current suppliers. 

-13- 

  
  
  
  
  
  
 
 
●  We  are  subject  to  risks related  to product defects,  which  could  lead  to  warranty  claims  in  excess of  our  warranty

provision or result in a significant or a large number of warranty or other claims in any given year. 

We provide a warranty for certain products for a period of 18 to 30 months and provide up to a five-year warranty for the 
ceramic components of our PX-branded products. We test our products in our manufacturing facilities through a variety of 
means; however, there can be no assurance that our testing will reveal latent defects in our products, which may not become 
apparent until after the products have been sold into the market. The testing may not replicate the harsh, corrosive, and varied 
conditions of the desalination and other plants in which they are installed. It is also possible that components purchased from 
our suppliers could break down under those conditions. Certain components of our turbochargers and pumps are custom-
made and may not scale or perform as required in production environments. Accordingly, there is a risk that we may have 
significant warranty claims or breach supply agreements due to product defects. We may incur additional cost of revenue if 
our warranty provisions are not sufficient to cover the actual cost of resolving issues related to defects in our products. If 
these  additional  expenses  are  significant,  they  could  adversely  affect  our  business,  financial  condition,  and  results  of 
operations. 

● 

If we are unable to protect our technology or enforce our intellectual property rights, our competitive position could 
be harmed, and we could be required to incur significant expenses to enforce our rights. 

Our competitive position depends on our ability to establish and maintain proprietary rights in our technology and to protect 
our  technology  from  copying  by  others.  We  rely  on  trade  secret,  patent,  copyright,  and  trademark  laws,  as  well  as 
confidentiality agreements with employees and third parties, all of which may offer only limited protection. We hold a number 
of U.S. and counterpart international patents, and when their terms expire, we could become more vulnerable to increased 
competition.  The  protection of our  intellectual  property  in  some  countries  may  be  limited. While  we have  expanded  our 
portfolio of patent applications, we do not know whether any of our pending patent applications will result in the issuance of 
patents or whether the examination process will require us to narrow our claims, and even if patents are issued, they may be 
contested, circumvented, or invalidated. Moreover, while we believe our issued patents and patent pending applications are 
essential to the protection of our technology, the rights granted under any of our issued patents or patents that may be issued 
in  the  future  may  not  provide  us  with  proprietary  protection  or  competitive  advantages,  and  as  with  any  technology, 
competitors may be able to develop similar or superior technologies now or in the future. In addition, our granted patents 
may not prevent misappropriation of our technology, particularly in foreign countries where intellectual property laws may 
not protect our proprietary rights as fully as those in the United States. This may render our patents impaired or useless and 
ultimately  expose  us  to  currently  unanticipated  competition.  Protecting  against  the  unauthorized  use  of  our  products, 
trademarks, and other proprietary rights is expensive, difficult, and in some cases, impossible. Litigation may be necessary 
in the future to enforce or defend our intellectual property rights or to determine the validity and scope of the proprietary 
rights of others. Intellectual property litigation could result in substantial costs and diversion of management resources, either 
of which could harm our business. 

●  Claims by others that we infringe their proprietary rights could harm our business. 

Third parties could claim that our technology infringes their intellectual property rights. In addition, we or our customers 
may be contacted by third parties suggesting that we obtain a license to certain of their intellectual property rights that they 
may believe we are infringing. We expect that infringement claims against us may increase as the number of products and 
competitors in our market increases and overlaps occur. In addition, to the extent that we gain greater visibility, we believe 
that we will face a higher risk of being the subject of intellectual property infringement claims. Any claim of infringement 
by a third party, even those without merit, could cause us to incur substantial costs defending against the claim and could 
distract management from our business. Furthermore, a party making such a claim, if successful, could secure a judgment 
that requires us to pay substantial damages. A judgment against us could also include an injunction or other court order that 
could prevent us from offering our products. In addition, we might be required to seek a license for the use of such intellectual 
property,  which  may  not  be  available  on  commercially  reasonable  terms,  or  at  all.  Alternatively,  we  may  be  required  to 
develop non-infringing technology, which could require significant effort and expense and may ultimately not be successful. 
Any  of  these  events  could  seriously  harm  our  business.  Third  parties  may  also  assert  infringement  claims  against  our 
customers. Because we generally indemnify our customers if our products infringe the proprietary rights of third parties, any 
such claims would require us to initiate or defend protracted and costly litigation on their behalf in one or more jurisdictions, 
regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of our 
customers. 

-14- 

  
  
  
  
  
 
 
●  We are currently involved in legal proceedings, and may be subject to additional future legal proceedings, that may

result in material adverse outcomes.  

In addition to intellectual property litigation risks discussed above, we are presently involved, and may become involved in 
the future, in various commercial and other disputes as well as related claims and legal proceedings that arise from time to 
time in the course of our business. We believe that we have substantial defenses in the matters currently pending; however, 
the process of settling or litigating claims is subject to uncertainties, and our views of these matters may change in the future. 
On January 20, 2015, we were named, among other defendants, in a purported class action on behalf of Energy Recovery 
stockholders, alleging securities act violations. In addition, we are party to other litigation including one with our former 
Chief Sales Officer alleging, among other things, wrongful termination. These and any future lawsuits to which we may 
become  a  party  will  likely  be  expensive  and  time  consuming  to  investigate,  defend  and  resolve,  and  will  divert  our 
management’s attention. Any litigation to which we are a party may result in an onerous or unfavorable judgment that may 
not be reversed upon appeal or in payments of substantial monetary damages or fines, or we may decide to settle lawsuits on 
similarly unfavorable terms, which could have an adverse effect our business, financial condition, or results of operations. 

●  Our business entails  significant  costs  that are  fixed or  difficult  to reduce  in  the short  term  while demand  for our

products is variable and subject to downturns, which may adversely affect our operating results. 

Our business requires investments in facilities, equipment, research and development, and training that are either fixed or 
difficult to reduce or scale in the short term. At the same time, the market for our products is variable and has experienced 
downturns  due  to  factors  such  as  economic  recessions,  increased  precipitation,  uncertain  global  financial  markets,  and 
political changes, many of which are outside of our control. During periods of reduced product demand, we may experience 
higher relative costs and excess manufacturing capacity, resulting in high overhead and lower gross profit margins while 
causing cash flow and profitability to decline. Similarly, although we believe that our existing manufacturing facilities are 
capable of meeting current demand and demand for the foreseeable future, the continued success of our business depends on 
our ability to expand our manufacturing, research and development, and testing facilities to meet market needs. If we are 
unable to respond timely to  an increase in demand, our revenue, gross profit margin, cash flow, and net income  may be 
adversely affected. 

● 

If we need additional capital to fund future growth, it may not be available on favorable terms, or at all. 

Our primary source of cash historically has been proceeds from the issuance of common stock and customer payments for 
our products and services. This has funded our operations, capital expenditures, and expansion. We may require additional 
capital from equity or debt financing in the future to fund our operations or respond to competitive pressures or strategic 
opportunities, such as an acquisition. We may not be able to secure such additional financing on favorable terms or at all. 
The terms of additional financing may place limits on our financial and operating flexibility. If we raise additional funds 
through  further  issuances  of  equity,  convertible  debt  securities,  or  other  securities  convertible  into  equity,  our  existing 
stockholders could suffer significant dilution in their percentage ownership of our company, and any new securities that we 
issue could have rights, preferences, or privileges senior to those of existing or future holders of our common stock. If we are 
unable to obtain necessary financing on terms satisfactory to us, if and when we require it, our ability to grow or support our 
business and to respond to business challenges or opportunities could be significantly limited. 

●  Our past acquisition  or future  acquisitions  could disrupt  our  business,  impact our margins,  cause dilution  to  our

stockholders, or harm our financial condition and operating results. 

We  acquired  privately-held  Pump  Engineering,  LLC  in  late  2009,  and  in  the  future,  we  may  invest  in  other  companies, 
technologies, or assets. We may not realize the expected benefits from our past or future acquisitions. We may not be able to 
find other suitable acquisition candidates, and we may not be able to complete acquisitions on favorable terms, if at all. If we 
do complete acquisitions, we cannot ensure that they will ultimately strengthen our competitive or financial position or that 
they will not be viewed negatively by customers, financial markets, investors, or the media. Acquisitions could also result in 
stockholder  dilution  or  significant  acquisition-related  charges  for  restructuring,  stock-based  compensation,  and  the 
amortization  of  purchased  technology  and  intangible  assets.  Expenses  resulting  from  impairment  of  acquired  goodwill, 
intangible assets, and purchased technology could also increase over time if the fair value of those assets decreases. A future 
change in market conditions, a downturn in our business, or a long-term decline in the quoted market price of our stock may 
result in a reduction of the fair value of acquisition-related assets. Any such impairment of goodwill or intangible assets could 
harm our operating results and financial condition. In addition, when we make an acquisition, we may have to assume some 
or all of that entity's liabilities, which may include liabilities that are not fully known at the time of the acquisition. Future 
acquisitions may reduce our cash available for operations and other uses. If we make future acquisitions, we may require 
additional cash or use shares of our common stock as payment, which would cause dilution to our existing stockholders.

Acquisitions  entail  a  number  of  risks  that  could  harm  our  ability  to  achieve  their  anticipated  benefits.  We  could  have 
difficulties  integrating  and  retaining  key  management  and  other  personnel,  aligning  product  plans  and  sales  strategies, 
coordinating  research  and  development  efforts,  supporting  customer  relationships,  aligning  operations,  and  integrating 
accounting, order processing, purchasing, and other support services. Since acquired companies have different accounting 
and  other  operational  practices,  we  may  have  difficulty  harmonizing  order  processing,  accounting,  billing,  resource 
management, information technology, and other systems company-wide. We may also have to invest more than anticipated 
in  product  or process  improvements.  Especially  with  acquisitions of privately-held or non-U.S.  companies,  we  may  face 
challenges developing and maintaining internal controls consistent with the requirements of the Sarbanes-Oxley Act and U.S. 
public  accounting  standards.  Acquisitions  may  also  disrupt  our  ongoing  operations,  divert  management  from  day-to-day 
responsibilities, and disrupt other strategic, research and development, marketing, or sales efforts. Geographic and time zone 
differences and disparate corporate cultures may increase the difficulties and risks of an acquisition. If integration of our 
acquired businesses or assets is not successful or disrupts our ongoing operations, acquisitions may increase our expenses, 
harm our competitive position, adversely impact our operating results and financial condition, and fail to achieve anticipated 
revenue, cost, competitive, or other objectives. 

● 

Insiders and principal stockholders will likely have significant influence over matters requiring stockholder approval.

Our directors, executive officers, and other principal stockholders beneficially own, in the aggregate, a substantial amount of 
our  outstanding  common  stock.  These  stockholders  could  likely  have  significant  influence  over  all  matters  requiring 
stockholder approval, including the election of directors and approval of significant corporate transactions such as a merger 
or other sale of our company or its assets. 

●  Anti-takeover provisions in our charter documents and under Delaware law could discourage, delay, or prevent a

change in control of our company and may affect the trading price of our common stock. 

Provisions in our amended and restated certificate of incorporation and bylaws may have the effect of delaying or preventing 
a change of control or changes in our management. Our amended and restated certificate of incorporation and amended and 
restated bylaws include provisions that: 

• 

• 

• 

• 

• 

• 

• 

• 

• 

authorize our Board of Directors to issue, without further action by the stockholders, up to 10,000,000 shares of
undesignated preferred stock; 

require that any action to be taken by our stockholders be effected at a duly called annual or special meeting and not
by written consent; 

specify that special meetings of our stockholders can be called only by our Board of Directors, the chairman of the
board, the chief executive officer, or the president; 

establish  an  advance  notice  procedure  for  stockholder  approvals  to  be  brought  before  an  annual  meeting  of  our
stockholders, including proposed nominations of persons for election to our Board of Directors; 

establish that our Board of Directors is divided into three classes, Class I, Class II, and Class III, with each class
serving staggered terms; 

provide that our directors may be removed only for cause; 

provide that vacancies on our Board of Directors may be filled only by a majority vote of directors then in office,
even though less than a quorum; 

specify that no stockholder is permitted to cumulate votes at any election of directors; and 

require a super-majority of votes to amend certain of the above mentioned provisions. 

In addition, we are subject to the provisions of Section 203 of the Delaware General Corporation Law regulating corporate 
takeovers. Section 203 generally prohibits us from engaging in a business combination with an interested stockholder subject 
to certain exceptions.

●  Regulations related to conflict minerals could adversely impact our business.  

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 (DRC)  and  adjoining  countries. As  a result,  in August 2012,  the SEC  adopted annual disclosure  and 
reporting requirements for those companies who use conflict minerals mined from the DRC and adjoining countries in their 
products. Based on our purchasing policy and supplier selection, it is considered unlikely that any conflict minerals are used 
in  the  manufacturing  of  our  products.  Nevertheless,  we  are  continuing  a  reasonable  country  of  origin  inquiry  and  have 
implemented a program of due diligence on the source and chain of custody for conflict minerals.  

There  are  costs  associated  with  complying  with  these  disclosure  requirements,  including  loss  of  customers  and  potential 
changes to products, processes, or sources of supply as a consequence of our 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” minerals, we cannot be sure that we will be able to obtain necessary 
materials 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 have implemented. 

●  Business interruptions may damage our facilities or those of our suppliers. 

Our operations and those of our suppliers may be vulnerable to interruption by fire, earthquake, flood, and other natural 
disasters, as well as power loss, telecommunications failure, and other events beyond our control. Our facilities in California 
are located near major earthquake faults and have experienced earthquakes in the past. If a natural disaster occurs, our ability 
to  conduct  our  operations  could  be  seriously  impaired,  which  could  harm  our  business,  financial  condition,  results  of 
operations, and cash flows. We cannot be sure that the insurance we maintain against general business interruptions will be 
adequate to cover all of our losses. 

●  We may have risks associated with security of our information technology systems. 

We make significant efforts to maintain the security and integrity of our information technology systems and data. Despite 
significant efforts to create security barriers to such systems, it is virtually impossible for us to entirely mitigate this risk. 
There is a risk of industrial espionage, cyber-attacks, misuse or theft of information or assets, or damage to assets by people 
who may gain unauthorized access to our facilities, systems, or information. Such cybersecurity breaches, misuse, or other 
disruptions  could  lead  to  the  disclosure  of  confidential  information,  improper  usage  and  distribution  of  our  intellectual 
property, theft, manipulation and destruction of private and proprietary data, and production downtimes. 

Although we actively employ measures to prevent unauthorized access to our information systems, preventing unauthorized 
use or infringement of our rights is inherently difficult. These events could adversely affect our financial results and any legal 
action in connection with any such cybersecurity breach could be costly and time-consuming and may divert management's 
attention and adversely affect the market's perception of us and our products. 

●  We may not meet the key performance indicators necessary to meet the two milestones in the Schlumberger license

agreement. 

The Schlumberger license agreement calls for certain milestone key performance indicators that if met will result in payments 
to  the  Company  of  $25  million  for  each  of  two  milestones.  Achievement  of  these  milestones  is uncertain,  and while  we 
believe we can meet the milestones, if we are unable to do so, the milestone payments will be delayed until such time as the 
milestones are met or not earned and received at all. Failure to meet said milestones may also jeopardize commercialization 
and the rate of adoption of our VorTeq hydraulic fracturing system. 

●  We may have risks associated with our new international tax optimization structure. 

In 2015, the Company implemented a new international tax optimization structure. Subsidiaries were established in Ireland 
and the U.S. parent company transferred the oil & gas intellectual property via platform licenses to ERI Energy Recovery 
Holdings Ireland Limited. The Company has undertaken extensive due diligence, implemented and continues to implement 
manufacturing,  R&D,  and  sales  operations  to  create  Irish  substance,  and  has  conferred  with  tax  experts  to  ensure  that 
uncertain tax positions are unlikely. It is possible that the new international tax structure could be examined by the Internal 
Revenue Service in the US and or the Tax Authorities in Ireland, and it is possible that such an examination could result in 
an unfavorable impact on the Company

Stockholders 

As of February 29, 2016, there were approximately 36 stockholders of record of our common stock as reported by our 
transfer agent, one of which is Cede & Co., a nominee for Depository Trust Company (DTC). All of the shares of common 
stock held by brokerage firms, banks, and other financial institutions as nominees for beneficial owners are deposited into 
participant accounts at DTC and are therefore considered to be held of record by Cede & Co. as one stockholder. 

Dividend Policy 

We have never declared or paid any dividends on our common stock, and we do not currently intend to pay any dividends 
on our common stock for the foreseeable future. Any future determination to pay dividends on our common stock will be, 
subject to applicable law, at the discretion of our Board of Directors and will depend upon, among other factors, our results 
of operations, financial condition, capital requirements, and contractual restrictions in loan or other agreements. 

Stock Repurchase Program 

In January 2016, our Board of Directors authorized a stock repurchase program under which shares, not to exceed $6.0 
million in aggregate cost, of our outstanding common stock may be repurchased through June 30, 2016 at the discretion of 
management. As of February 29, 2016, 673,700 shares at an aggregate cost of $4.1 million had been repurchased under this 
authorization. 

A  stock  repurchase  program  was  not  in  place  during  the  year  ended  December  31,  2015,  therefore  no  shares  were 

repurchased during 2015. 

In February 2014, our Board of Directors authorized a stock repurchase program under which up to three million shares, 
not to exceed $6.0 million in aggregate cost, of our outstanding common stock could be repurchased through December 31, 
2014 at the discretion of management. During the year ended December 31, 2014, 696,853 shares at an aggregate cost of 
$2.8 million were repurchased under this authorization. This 2014 repurchase authorization expired on December 31, 2014. 

Sales of Unregistered Securities 

During the year ended December 31, 2015, warrants to purchase 200,000 shares of common stock were exercised for 

cash at a price of $1.00 per share. The proceeds received from this exercise totaled $200,000. 

During  the  year  ended  December  31,  2014,  warrants  to  purchase  450,000  shares  of  common  stock  were  exercised. 
Warrants to purchase 50,000 shares of common stock were exercised for cash at a price of $1.00 per share. The proceeds 
received  from  this  exercise  totaled  $50,000.  Warrants  to  purchase  400,000  shares  of  common  stock  were  exercised  for 
311,111 shares of common stock in lieu of cash proceeds. The remaining 88,889 warrants were cancelled and considered 
payment for the exercise.

During  the  year  ended  December  31,  2013,  warrants  to  purchase  300,000  shares  of  common  stock  were  exercised. 
Warrants to purchase 100,000 were exercised for cash at a price of $1.00 per share. The proceeds received from this exercise 
totaled $100,000. Warrants to purchase 200,000 shares of common stock were exercised for 180,276 shares in lieu of cash 
proceeds. The remaining 19,724 warrants were cancelled and considered payment for the exercise.  

These shares issued pursuant to the warrants were not registered under the Securities Act of 1933, as amended, in reliance 

upon the exemption set forth in Section 4(2) of that Act for transactions not involving a public offering. 

Stock Performance Graph 

The following graph shows the cumulative total stockholder return of an investment of $100 on December 31, 2010 in 
(i)  our  common  stock,  (ii)  common  stock  of  a  selected  group  of  peer  issuers  (“Peer  Group”),  and  (iii)  the  NASDAQ 
Composite  Index.  Cumulative  total  return  assumes  the  reinvestment  of  dividends,  although  dividends  have  never  been 
declared on our stock, and is based on the returns of the component companies weighted according to their capitalizations as 
of  the  end  of  each  quarterly  period.  The  NASDAQ  Composite  Index  tracks  the  aggregate  price  performance  of  equity 
securities traded on the NASDAQ. The Peer Group tracks the weighted average price performance of equity securities of 
seven companies in our industry: Consolidated Water Co. Ltd.; Flowserve Corp.; Hyflux Ltd., Kurita Water Industries Ltd.; 
Pentair PLC; Tetra Tech, Inc.; and The Gorman-Rupp Company. The return of each component issuer of the Peer Group is 
weighted  according  to  the  respective  issuer’s  stock  market  capitalization  at  the  end  of  each  period  for  which  a  return  is 
indicated. Our stock price performance shown in the graph below is not indicative of future stock price performance. 

The following graph and its related information is not “soliciting material,” is not deemed “filed” with the SEC, and is 
not to be incorporated by reference into any filing of the Company under the 1933 Securities Act or 1934 Securities Exchange 
Act, whether made before or after the date hereof and irrespective of any general incorporation language contained in such

Item 7 — Management’s Discussion and Analysis of Financial Condition and Results of Operations  

The following Management Discussion and Analysis is intended to help the reader understand our results of operations 
and  financial  condition.  It  should  be  read  in  conjunction  with  the  Consolidated  Financial  Statements  and  related  Notes 
included in “Item 8 — Financial Statements and Supplementary Data” in this Report. 

Overview 

We are an energy solutions provider to industrial fluid flow markets worldwide. We make industrial processes more 
operating and capital expenditure efficient. Our solutions convert wasted pressure energy into a reusable asset and preserve 
or  eliminate  pumping  technology  in  hostile  processing  environments.  Our  core  competencies  are  fluid  dynamics  and 
advanced  material  science.  Our  company  was  founded  in  1992,  and  we  introduced  the  initial  version  of  our  Pressure 
Exchanger® energy recovery device in early 1997 for seawater reverse osmosis desalination. In December 2009, we acquired 
Pump Engineering, LLC, which manufactured centrifugal energy recovery devices, known as turbochargers, as well as high-
pressure pumps. In 2012, we introduced the IsoBoost and IsoGen products for use in the oil & gas industry. In 2015, we 
conducted field trials for the VorTeq hydraulic pumping solution also for use in the oil & gas industry for oil field hydraulic 
fracturing operations and entered into a fifteen year license agreement with Schlumberger Technology Corporation. 

In January 2015, Mr. Thomas S. Rooney, Jr., resigned as President and Chief Executive Officer of the Company and 

also as a member of the Board of Directors.  

On April 24, 2015, the Board of Directors appointed Mr. Joel Gay, then Chief Financial Officer, as President and Chief 

Executive Officer and as a member of the Board of Directors. 

In June 2015, the Board of Directors appointed Mr. Chris Gannon as Chief Financial Officer. 

With  the  appointments  of  a  new  Chief  Executive  Officer  and  Chief  Financial  Officer,  new  internal  reporting  was 
developed for making operating decisions and assessing financial performance. Beginning with the third quarter of 2015, a 
new internal organizational and reporting structure was implemented and we began reporting segment information on a basis 
reflecting the new structure. There were no adjustments to prior period amounts, however amounts have been reclassified to 
reflect this new internal reporting structure for comparative purposes.  

Our reportable operating segments consist of the Water Segment and the Oil & Gas Segment. These segments are based 
on the industries in which the solutions are sold, the type of energy recovery device sold, and the related solution and service. 

Water Segment 

The Water Segment consists of revenue associated with solutions sold for use in reverse osmosis water desalination, as 
well  as  the  related  identifiable  expenses.  Our  revenue  is  principally  derived  from  the  sale  of  energy  recovery  devices, 
however, we also derive revenue from the sale of our high-pressure and circulation pumps, which we manufacture and sell 
in connection with our energy recovery devices for use in desalination plants. Additionally, we receive revenue from the sale 
of spare parts and services, including start-up and commissioning services that we provide for our customers.  

With respect to revenue from our energy recovery devices in our Water Segment, a significant portion of our product 
revenue typically has been generated by sales to a limited number of large engineering, procurement, and construction, or 
EPC, firms, which are involved with the design and construction of larger desalination plants. Sales to these firms often 
involve a long sales cycle, which can range from sixteen (16) months to thirty-six (36) months. A single large desalination 
project can generate an order for numerous energy recovery devices and generally represents an opportunity for significant 
revenue.  We  also  sell  our  devices  to  many  small-  to  medium-sized  original  equipment  manufacturers,  or  OEMs,  which 
commission smaller desalination plants, order fewer energy recovery devices per plant, and have shorter sales cycles.  

We often experience substantial fluctuations in our Water Segment in product revenue from quarter to quarter and from 
year to year due to the fact that a single order for our energy recovery devices by a large EPC firm for a particular plant may 
represent significant revenue. In addition, historically our EPC customers tend to order a significant amount of equipment 
for delivery in the fourth quarter, and as a consequence, a significant portion of our annual sales typically occurs during that 
quarter. The historical pattern of significant sales occurring in the fourth quarter was reflected in that period in 2015, 2014, 
and 2013. Normal seasonality trends also generally lead to our lowest revenue being in the first quarter of the year.

A limited number of our customers account for a substantial portion of our product revenue and accounts receivable in 
the Water Segment. Revenue from customers representing 10% or more of product revenue varies from period to period. For 
the years ended December 31, 2015, 2014, and 2013, one customer per year accounted for approximately 14%, 14%, and 
15%, respectively, of our product revenue. See Note 14 — “Concentrations” in the Notes to the Consolidated Financial 
Statements for further details on customer concentration. 

At December 31, 2015, two customers accounted for 26% and 18%, respectively, of our accounts receivable and unbilled 
receivable  balance.  At  December  31,  2014,  two  customers  accounted  for  32%  and  11%  of  our  accounts  receivable  and 
unbilled receivable balance. See Note 14 — “Concentrations” in the Notes to the Consolidated Financial Statements for 
further details on customer concentration. 

During the years ended December 31, 2015, 2014, and 2013, most of our product revenue was attributable to sales outside 
of  the United States. We  expect  sales outside  of  the United  States  to remain  a  significant  portion  of  our  revenue  for  the 
foreseeable future. 

Oil & Gas Segment 

The Oil & Gas Segment consists of revenue associated with solutions sold for use in hydraulic fracturing, gas processing, 
and chemical processing, as well as the related identifiable expenses. In the past several years, we have invested significant 
research and development costs to expand our business into pressurized fluid flow industries within the oil & gas industry. 
In 2014, we announced a new product for the hydraulic fracturing industry, the VorTeq hydraulic fracturing system. Field 
trials were initiated for the VorTeq in the second quarter of 2015 and successfully completed in December 2015.  

In October 2015, through our subsidiary ERI Energy Recovery Ireland Ltd., we entered into a License Agreement with 
Schlumberger Technology Corporation (“Schlumberger”), a subsidiary of Schlumberger Limited. The agreement has a term 
of  fifteen  (15)  years  for  the  exclusive,  worldwide  right  to  use  our  VorTeq  technology  for  hydraulic  fracturing  onshore 
operations.  The  agreement  includes  $125  million  in  payments  paid  in  stages:  a  $75  million  upfront,  exclusive  license 
payment, amortized over the 15 year license term; two separate $25 million payments upon achieving two milestones, to be 
recognized when achieved; and recurring royalty payments after the product is commercialized throughout the term of the 
Agreement.  

The revenue related to the exclusive license payment will be recognized pro-ratably over the fifteen year agreement. 
Revenue from each milestone payment will be recognized when the milestone is reached. Revenue from the recurring royalty 
payments will be recognized when earned throughout the term of the agreement. 

For the year ended December 31, 2015, we recognized revenue for the straight line, fifteen year amortization of the 
upfront fees related to our license agreement with Schlumberger, revenue from commissioning services, and fees from the 
cancellation of a sales order. For the year ended December 31, 2014, we recognized rental income from the operating lease 
and subsequent lease buy-out of an IsoGen system. For the year ended December 31, 2013, no revenue related to the Oil & 
Gas segment was recognized. 

For the years ended December 31, 2015 and 2014, one customer per year accounted for substantially all of the Oil & 
Gas  revenue  recognized.  No  revenue  related  to  the  Oil  &  Gas  segment  was  recognized  in  2013.  See  Note  14  — 
“Concentrations” in the Notes to the Consolidated Financial Statements for further details on customer concentration. 

Critical Accounting Policies and Estimates 

Our Consolidated Financial Statements are prepared in accordance with generally accepted accounting principles in the 
United States, or GAAP. These accounting principles require us to make estimates and judgments that can affect the reported 
amounts of assets and liabilities as of the date of the Consolidated Financial Statements as well as the reported amounts of 
revenue and expense during the periods presented. We believe that the estimates and judgments upon which we rely are 
reasonable based upon information available to us at the time that we make these estimates and judgments. To the extent that 
there are material differences between these estimates and actual results, our consolidated financial results will be affected. 
The accounting policies that reflect our more significant estimates and judgments and which we believe are the most critical 
to aid in fully understanding and evaluating our reported financial results are revenue recognition; allowance for doubtful 
accounts; allowance for product warranty; valuation of stock options; valuation and impairment of goodwill and acquired 
intangible assets; useful lives for depreciation and amortization; valuation adjustments for excess and obsolete inventory; 
deferred taxes and valuation allowances on deferred tax assets; and evaluation and measurement of contingencies, including 
contingent consideration.

The following is not intended to be a comprehensive list of all of our accounting policies or estimates. Our accounting 
policies are more fully described in Note 2 — “Summary of Significant Accounting Policies,” included in “Item 8 — Financial 
Statements and Supplementary Data” in this Report. 

Revenue Recognition  

Product revenue recognition 

We recognize revenue when the earnings process is complete, as evidenced by a written agreement with the customer, 
transfer of title, fixed pricing that is determinable, and collection that is reasonably assured. Transfer of title typically occurs 
upon shipment of the equipment pursuant to a written purchase order or contract. The portion of the sales agreement related 
to the field services and training for commissioning of our devices in a desalination plant is deferred until we have performed 
such  services.  We  regularly  evaluate  our  revenue  arrangements  to  identify  deliverables  and  to  determine  whether  these 
deliverables are separable into multiple units of accounting.  

Under our revenue recognition policy, evidence of an arrangement has been met when we have an executed purchase 
order, sales order, or stand-alone contract. Typically, smaller projects utilize sales or purchase orders that conform to standard 
terms and conditions. 

The specified product performance criteria for our PX device pertain to the ability of our product to meet its published 
performance specifications and warranty provisions, which our products have demonstrated on a consistent basis. This factor, 
combined with historical performance metrics, provides our management with a reasonable basis to conclude that its PX 
device  will  perform  satisfactorily  upon  commissioning  of  the  plant.  To  ensure  this  successful  product  performance,  we 
provide  service  consisting  principally  of  supervision  of  customer  personnel  and  training  to  the  customers  during  the 
commissioning of the plant. The installation of the PX device is relatively simple, requires no customization, and is performed 
by the customer under the supervision of our personnel. We defer the value of the service and training component of the 
contract and recognize such revenue as services are rendered. Based on these factors, our management has concluded that, 
for sale of PX devices, as well as for turbochargers and pumps, delivery and performance have been completed upon shipment 
or delivery when title transfers based on the shipping terms. 

We  perform  an  evaluation  of  credit  worthiness  on  an  individual  contract  basis  to  assess  whether  collectability  is 
reasonably  assured.  As  part  of  this  evaluation,  our  management  considers  many  factors  about  the  individual  customer, 
including the underlying financial strength of the customer and/or partnership consortium and management’s prior history or 
industry-specific knowledge about the customer and its supplier relationships. For smaller projects, we require the customer 
to  remit  payment  generally  within  30  to  90  days  after  product  delivery.  In  some  cases,  if  credit  worthiness  cannot  be 
determined, prepayment or other security is required from smaller customers. 

We establish separate units of accounting for contracts, as our contracts with customers typically include one or both of 

the following deliverables, and there is no right of return under the terms of the contract. 

●  Products 
●  Commissioning  which  includes  supervision  of  the  installation,  start-up,  and  training  to  ensure  that  the
installation performed by the customer, which is relatively simple and straightforward, is completed consistent
with the recommendations under the factory warranty.  

The commissioning services’ element of our contracts represents an incidental portion of the total contract price. The 
allocable  consideration  for  these  services  relative  to  that  for  the  underlying  products  has  been  well  under  1%  of  any 
arrangement. Commissioning is often bundled into the large stand-alone contracts, and we frequently sell products without 
commissioning since our product can be easily installed in a plant without supervision. These facts and circumstances validate 
that the delivered element has value on a stand-alone basis and should be considered a separate unit of accounting.

Having  established  separate  units  of  accounting,  we  then  take  the  next  steps  to  allocate  amounts  to  each  unit  of 
accounting. With respect to products, we have established vendor specific objective evidence (“VSOE”) based on the price 
at which such products are sold separately without commissioning services. With respect to commissioning, we charge out 
our engineers for field visits to customers based on a stand-alone standard daily field service charge as well as a flat service 
rate for travel, if applicable. This has been determined to be the VSOE of the service based on stand-alone sales of other 
comparable professional services at consistent pricing.  

The  amount  allocable  to  the  delivered  unit  of  account  (in  our  case  the  product)  is  limited  to  the  amount  that  is  not 
contingent upon the delivery of additional items or meeting specified performance conditions. We adhere to consistent pricing 
in both stand-alone sale of products and professional services and the contractual pricing of products and commissioning of 
services in bundled arrangements. 

For large projects, stand-alone contracts are utilized. For these contracts, consistent with industry practice, our customers 
typically require their suppliers, including Energy Recovery, to accept contractual holdback provisions (also referred to as a 
retention payment) whereby the final amounts due under the sales contract are remitted over extended periods of time or 
alternatively, stand-by letters of credit are issued to guarantee performance. These retention payments typically range between 
5%  and  15%,  of  the  total  contract  amount  and  are  due  and  payable  when  the  customer  is  satisfied  that  certain  specified 
product performance criteria have been met upon commissioning of the desalination plant, which may be up to 24 months 
from the date of product delivery as described further below. 

Under stand-alone contracts, the usual payment arrangements are summarized as follows: 

•  an advance payment due upon execution of the contract, typically 10% to 20% of the total contract amount. This advance
payment is accounted for as deferred revenue until shipment or when products are delivered to the customer, depending 
on the Incoterms and transfer of title; 

•  a payment ranging from 50% to70% of the total contract is typically due upon delivery of the product. This payment is
often  divided  into  two  parts.  The  first  part,  which  is  due  30  to  60  days  following  delivery  of  the  product  and
documentation,  is  invoiced  upon  shipment  when  the  product  revenue  is  recognized  and  results  in  an  open  accounts
receivable  with  the  customer.  The  second  part  is  typically  due  90  to  120  days  following  product  delivery  and
documentation. This payment is booked to unbilled receivables upon shipment when the product revenue is recognized,
and it is invoiced to the customer upon notification that the equipment has been received or when the time period has
expired. We have no performance obligation to complete to be legally entitled to this payment. It is invoiced based on
the passage of time. 

•  a  final  retention  payment  of  usually  5%  to  15%  of  the  contract  amount  is  due  either  at  the  completion  of  plant
commissioning or upon the issuance of a stand-by letter of credit, which is typically issued up to 24 months from the
delivery date of products and documentation. This payment is recorded to unbilled receivables upon shipment when the
product revenue is recognized, and it is invoiced to the customer when it is determined that commissioning is complete 
or the stand-by letter of credit has been issued. This payment is not contingent upon the delivery of commissioning
services. The Company had no performance obligation to complete to be legally entitled to this payment. It is invoiced
based on the passage of time. 

We do not provide our customers with a right of product return; however, we will accept returns of products that are 
deemed to be damaged or defective when delivered that are covered by the terms and conditions of the product warranty. 
Product returns have not been significant. 

Shipping and handling charges billed to customers are included in product revenue. The cost of shipping to customers is 

included in cost of revenue. 

License and development revenue recognition 

License  revenue  is  comprised  of  fees  received  in  connection  the  Schlumberger  License  Agreement.  See  Note  16  – 
Schlumberger License Agreement. The agreement comprises a 15 year exclusive license for the our VorTeq technology, 
development services to commercialize the technology, support services, and, in the event commercialization is successful, 
supply  and  servicing  of  certain  components  of  the  VorTeq  and  development  services  related  to  integration  of  the 
commercialized technology with future Schlumberger equipment. Various types of payments to the Company are provided 
in  the  agreement,  including  an  upfront  exclusive  license  fee,  developmental  milestones,  and  payments  for  supply  and 
servicing of components subsequent to commercialization. All payments are non-refundable.  

-26- 

  
  
  
  
  
  
  
  
  
  
  
  
  
We recognize license revenue in accordance with ASC 605 “Revenue Recognition”, subtopic ASC 605-25 “ Revenue 
with  Multiple  Element  Arrangements  ”  and  subtopic  ASC  605-28  “  Revenue  Recognition-Milestone  Method  ”,  which 
provides accounting guidance for revenue recognition for arrangements with multiple deliverables and guidance on defining 
the milestone and determining when the use of the milestone method of revenue recognition for research and development 
transactions is appropriate, respectively. 

For  multiple-element  arrangements,  each  deliverable  is  accounted  for  as  a  separate  unit  of  accounting  if  both  the 
following criteria are met: (1) the delivered item or items have value to the customer on a standalone basis and (2) for an 
arrangement that includes a general right of return relative to the delivered item(s), delivery or performance of the undelivered 
item(s) is considered probable and substantially in our control. Contingent deliverables within multiple element arrangements 
are excluded from the evaluation of the units of accounting. Non-refundable, upfront license fees where we have continuing 
obligation to perform are recognized over the period of the continuing performance obligation. The Schlumberger License 
Agreement was determined to include a single unit of accounting comprising the license, research and development, and 
support services. The initial upfront fee of $75 million will be recognized on a straight-line basis over the fifteen year term 
of the arrangement based on the performance period of the last or final deliverables, which include the license and support. 

We recognize revenue from milestone payments when: (i) the milestone event is substantive and its achievability has 
substantive uncertainty at the inception of the agreement, and (ii) it does not have ongoing performance obligations related 
to the achievement of the milestone earned. Milestone payments are considered substantive if all of the following conditions 
are met, the milestone payment: (a) is commensurate with either the Company’s performance subsequent to the inception of 
the arrangement to achieve the milestone or the enhancement of the value of the delivered item or items as a result of a 
specific outcome resulting from the Company’s performance subsequent to the inception of the arrangement to achieve the 
milestone; (b) relates solely to past performance; and (c) is reasonable relative to all of the deliverables and payment terms 
(including other potential milestone consideration) within the arrangement. The Schlumberger License Agreement includes 
two substantive milestones of $25 million each due on achieving specified development milestones. No revenues associated 
with achievement of the milestones have been recognized to date. 

Research and Development Expense 

Research  and  development  expenses  consist  of  costs  incurred  for  internal  projects  and  research  and  development 
activities performed for technology licensed to third parties. These costs include our direct and research-related overhead 
expenses, which include salaries and other personnel-related expenses (including stock-based compensation), occupancy-
related costs, depreciation of facilities, as well as external costs, and are expensed as incurred. Costs to acquire technologies 
that are utilized in research and development and that have no alternative future use are expensed when incurred. 

Allowances for Doubtful Accounts 

We record a provision for doubtful accounts based on historical experience and a detailed assessment of the collectability 
of our accounts receivable. In estimating the allowance for doubtful accounts, we consider, among other factors, the aging of 
the accounts receivable, our historical write-offs, the credit worthiness of each customer, and general economic conditions. 
Account balances are charged off against the allowance when we believe that it is probable that the receivable will not be 
recovered. Actual write-offs may be in excess of our estimated allowance. 

Warranty Costs 

We sell products with a limited warranty for a period ranging from eighteen (18) months to five (5) years. We accrue for 
warranty costs based on estimated product failure rates, historical activity, and expectations of future costs. Periodically, we 
evaluate and adjust the warranty costs to the extent that actual warranty costs vary from the original estimates. 

-27- 

  
  
  
  
  
  
  
  
  
  
 
 
Stock-based Compensation 

We measure and recognize stock-based compensation expense based on the fair value measurement for all stock-based 
awards  made  to  our  employees  and  directors  —  including  restricted  stock  units  (“RSUs”),  restricted  shares  (“RS”),  and 
employee stock options — over the requisite service period (typically the vesting period of the awards). The fair value of 
RSUs and RS is based on our stock price on the date of grant. At December 31, 2015, there were no outstanding RSUs or 
RS. The fair value of stock options is calculated on the date of grant using the Black-Scholes option pricing model, which 
requires a number of complex assumptions including expected life, expected volatility, risk-free interest rate, and dividend 
yield. The estimation of awards that will ultimately vest requires judgment, and to the extent that actual results or updated 
estimates differ from our current estimates, such amounts are recorded as a cumulative adjustment in the period in which the 
estimates are revised. See Note 12 — “Stock-based Compensation” for further discussion of stock-based compensation. 

Goodwill and Other Intangible Assets 

The  purchase  price  of  an  acquired  company  is  allocated  between  intangible  assets  and  the  net  tangible  assets  of  the 
acquired business with the residual purchase price recorded as goodwill. The determination of the value of the intangible 
assets acquired involves certain judgments and estimates. These judgments can include, but are not limited to, the cash flows 
that an asset is expected to generate in the future and the appropriate weighted average cost of capital. 

Acquired intangible assets with determinable useful lives are amortized on a straight-line or accelerated basis over the 
estimated periods benefited, ranging from one to 20 years. Acquired intangible assets with contractual terms are amortized 
over  their  respective  legal  or  contractual  lives.  Customer  relationships  and  other  non-contractual  intangible  assets  with 
determinable lives are amortized over periods ranging from five to 20 years.  

We evaluate the recoverability of intangible assets by comparing the carrying amount of an asset to estimated future net 
undiscounted cash flows generated by the asset. If such assets are considered to be impaired, the impairment recognized is 
measured as the amount by which the carrying amount of the assets exceeds the fair value of the assets. The evaluation of 
recoverability involves estimates of future operating cash flows based upon certain forecasted assumptions, including, but 
not limited to, revenue growth rates, gross profit margins, and operating expenses over the expected remaining useful life of 
the related asset. A shortfall in these estimated operating cash flows could result in an impairment charge in the future. 

Goodwill is not amortized, but is evaluated annually for impairment at the reporting unit level or when indicators of a 
potential impairment are present. We estimate the fair value of the reporting unit using the discounted cash flow and market 
approaches. Forecast of future cash flows are based on our best estimate of future net sales and operating expenses, based 
primarily on expected category expansion, pricing, market segment, and general economic conditions.  

As  of  December  31,  2015  and  2014,  acquired  intangibles,  including  goodwill,  relate  to  the  acquisition  of  Pump 
Engineering, LLC during the fourth quarter of 2009. See Note 6 — “Goodwill and Intangible Assets” for further discussion 
of intangible assets. 

Property and Equipment 

Property and equipment is recorded at cost and reduced by accumulated depreciation. Depreciation expense is recognized 
over  the  estimated  useful  lives  of  the  assets  using  the straight-line  method.  Estimated  useful  lives  are  three  to  ten  years. 
Certain equipment used in the development and manufacturing of ceramic components is depreciated over estimated useful 
lives  of  up  to  ten  years.  Leasehold  improvements  represent  remodeling  and  retrofitting  costs  for  leased  office  and 
manufacturing space and are depreciated over the shorter of either the estimated useful lives or the term of the lease. Software 
purchased for internal use consists primarily of amounts paid for perpetual licenses to third-party software providers and 
installation costs. Software is depreciated over the estimated useful lives of three (3) to five (5) years. Estimated useful lives 
are  periodically  reviewed,  and  when  appropriate,  changes  are  made  prospectively.  When  certain  events  or  changes  in 
operating conditions occur, asset lives may be adjusted and an impairment assessment may be performed on the recoverability 
of the carrying amounts. Maintenance and repairs are charged directly to expense as incurred.

Inventories 

Inventories are stated at the lower of cost (using the first-in, first-out “FIFO” method) or market. We calculate inventory 
valuation adjustments for excess and obsolete inventory based on current inventory levels, movement, expected useful lives, 
and estimated future demand of the products and spare parts. 

Income Taxes 

Current and non-current tax assets and liabilities are based upon an estimate of taxes refundable or payable for each of 
the jurisdictions in which we are subject to tax. In the ordinary course of business, there is inherent uncertainty in quantifying 
income tax positions. We assess income tax positions and record tax benefits for all years subject to examination based upon 
our evaluation of the facts, circumstances, and information available at the reporting dates. For those tax positions where it 
is more likely than not that a tax benefit will be sustained, we record the largest amount of tax benefit with a greater than 
50% likelihood of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant 
information. For those income tax positions where it is not more likely than not that a tax benefit will be sustained, no tax 
benefit  is  recognized  in  the  financial  statements.  When  applicable,  associated  interest  and  penalties  are  recognized  as  a 
component of income tax expense. Accrued interest and penalties are included within the related tax asset or liability on the 
Consolidated Balance Sheets. 

Deferred income taxes are provided for temporary differences arising from differences in bases of assets and liabilities 
for tax and financial reporting purposes. Deferred income taxes are recorded on temporary differences using enacted tax rates 
in effect for the year in which the temporary differences are expected to reverse. The effect of a change in tax rates on deferred 
tax assets and liabilities is recognized in income in the period that includes the enactment date. Deferred tax assets are reduced 
by  a  valuation  allowance when,  in  the  opinion of  management,  it  is  more  likely  than not  that  some  portion  or  all  of  the 
deferred  tax  assets  will  not  be  realized.  Significant  judgment  is  required  in  determining  whether  and  to  what  extent  any 
valuation allowance is needed on our deferred tax assets. In making such a determination, we consider all available positive 
and negative evidence including recent results of operations, scheduled reversals of deferred tax liabilities, projected future 
income, and available tax planning strategies. As of December 31, 2015, we have a valuation allowance of approximately 
$21.4 million to reduce our deferred income tax assets to the amount expected to be realized. See Note 10 — “Income Taxes” 
for further discussion of the tax valuation allowance. 

Our operations are subject to income and transaction taxes in the U.S. and in foreign jurisdictions. Significant estimates

Our product revenue increased by $13.2 million, or 44%, to $43.7 million for the year ended December 31, 2015 from 
$30.4 million for the year ended December 31, 2014. The increase in revenue was primarily due to significantly higher mega-
project (MPD) shipments in the current year compared to the previous year as well as higher OEM and aftermarket shipments. 
Of the $13.2 million increase in revenue, $9.8 million related to Water MPD sales, $2.8 million related to Water OEM sales, 
$1.2 million related to Water aftermarket sales. Water revenue was offset by a decrease in Oil & Gas revenue of $0.6 million 
related to the lease buy-out of an IsoGen system in 2014 and the commissioning of that system in early 2015.  

License and development revenue 

The  increase  in  License  and  development  revenue  was  due  to  the  recognition  in  2015  of  $1.0  million  in  revenue 
associated with the exclusivity agreement with Schlumberger. The $1.0 million is representative of the straight-line basis of 
revenue recognition over the fifteen years term of the agreement.

Product gross profit represents our product revenue less our product cost of revenue. Our product cost of revenue consists 
primarily of raw materials, personnel costs (including stock-based compensation), manufacturing overhead, warranty costs, 
depreciation expense, and manufactured components. For the year ended December 31, 2015, total product gross profit as a 
percentage of product revenue was 56% compared to 55% for the year ended December 31, 2014.  

The increase in product gross profit as a percentage of product revenue in 2015 compared to 2014 was primarily due to 
higher production  volume  and  a  shift  in  product  mix  toward  PX  devices due  to  increased  MPD  sales volume.  A shift  in 
product  mix  toward  PX devices  causes  an increase  in  total  gross profit as  PX devices  have  a  higher  gross profit  margin 
compared to turbochargers and pumps. The increase in product gross profit margin was slightly offset by a decrease in the 
gross profit margin of the oil & gas segment due to cost associated with the commissioning of an IsoGen in 2015. 

Future gross profit is highly dependent on the product and customer mix of our product revenue, overall market demand 
and  competition,  and  the  volume  of  production  in  our  manufacturing  plant  that  determines  our  operating  leverage. 
Accordingly, we are not able to predict our future gross profit levels with certainty. We do believe, however, that the levels 
of gross profit margin are sustainable to the extent that volume persists, our product mix favors PX devices, pricing remains 
stable, and we continue to realize cost saving through production efficiencies and enhanced yields. 

Manufacturing headcount increased to 42 for the year ended December 31, 2015 from 38 for the year ended December 

31, 2014. 

Stock-based compensation expense included in cost of revenue was $130,000 for the year ended December 31, 2015 and 

$101,000 for the year ended December 31, 2014. 

General and administrative  

General and administrative expense increased by $5.7 million, or 40%, to $19.8 million for the year ended December 
31, 2015 from $14.1 million for the year ended December 31, 2014. General and administrative expense as a percentage of 
product revenue decreased to 45% for the year ended December 31, 2015 compared to 46% for the year ended December 31, 
2014 primarily due to higher product revenue period over period.

Of the $5.7 million net increase in general and administrative expense, $2.0 million related to increased stock-based 
compensation expense, including non-recurring expense associated with the resignation of the Chief Executive Officer in 
January 2015; $1.8 million related to compensation and employee-related benefits, that included non-recurring termination 
benefits associated with a reduction in force in the first quarter of 2015; $1.1 million related to professional, legal, and other 
administrative costs, including non-recurring expenses related to the termination of the former Senior Vice-President of Sales 
in 2014; $0.9 million related to the reversal of VAT in the first quarter of 2014 that was expensed in 2011 and prior years; 
$0.4  million  related  to  bad  debt  expense,  occupancy  costs,  and  other  taxes;  and  $0.2  million  related  to  the  fair  value 
remeasurement of the contingent consideration settled in 2014. Offsetting the increases was a decrease of $0.7 million in 
other general and administrative miscellaneous costs.  

General and administrative headcount decreased to 27 for the year ended December 31, 2015 from 28 for the year ended 

December 31, 2014.  

Stock-based compensation expense included in general and administrative expense was $3.1 million for the year ended 
December 31, 2015 and $1.2 million for the year ended December 31, 2014. The increase in stock-based compensation is 
primarily related to the increased value of options granted to non-employee directors in February 2015, the full vesting of 
restricted shares granted to a non-employee director in December 2014, and non-recurring expenses related to the accelerated 
vesting and modification of options associated with the resignation of the former Chief Executive Officer in the first quarter 
of 2015. 

Sales and marketing  

Sales and marketing expense decreased by $1.2 million, or 11%, to $9.3 million for the year ended December 31, 2015 
from $10.5 million for the year ended December 31, 2014. Sales and marketing expense as a percentage of product revenue 
decreased to 21% for the year ended December 31, 2015 from 35% for the year ended December 31, 2014, primarily due to 
lower sales and marketing expense and higher product revenue period over period. 

Of  the  $1.2  million  net  decrease  in  sales  and  marketing  expense,  $1.3  million  related  to  marketing,  professional, 
occupancy, and other sales and marketing costs and $0.7 million related to compensation and employee-related benefits. The 
decreases were offset by an increase of $0.8 million related to sales commissions and bonuses. 

Sales  and  marketing  headcount  decreased  to  28  for  the  year  ended  December  31,  2015  from  36  for  the  year  ended 

December 31, 2014. 

Stock-based compensation expense included in sales and marketing expense was $436,000 for the year ended December 

31, 2015 and $487,000 for the year ended December 31, 2014. 

Sales and marketing expenditures may increase in the future as we continue to advance our existing technologies and 

develop new energy recovery and efficiency-enhancing solutions for markets outside of seawater desalination.  

Research and development  

Research and development expense decreased by $2.0 million, or 21%, to $7.7 million for the year ended December 31, 
2015 from $9.7 million for the year ended December 31, 2014. Research and development expense as a percentage of product 
revenue decreased to 18% for the year ended December 31, 2015 from 32% for the year ended December 31, 2014, primarily 
due to decreased research and development costs and higher product revenue period over period. 

Of  the  $2.0  million  decrease  in  research  and  development  expense,  $2.4  million  related  to  direct  research  and 
development project costs associated with new product initiatives and $0.3 million related to consulting and professional 
services. The decreases were offset by an increase of $0.7 million related to compensation, employee-related benefits, and 
occupancy costs. 

Research and development headcount decreased to 17 for the year ended December 31, 2015 from 22 for the year ended 

December 31, 2014.  

Stock-based  compensation  expense  included  in  research  and  development  expense  was  $354,000  for  the  year  ended 

December 31, 2015 and $342,000 for the year ended December 31, 2014.

Amortization of intangible assets 

Amortization of intangible assets is primarily related to finite-lived intangible assets acquired as a result of our purchase 
of Pump Engineering, LLC in December 2009. Amortization expense decreased by $0.2 million, or 25%, to $0.6 million for 
the year ended December 31, 2015 from $0.8 million for the year ended December 31, 2014. The decrease was due to the 
full amortization of all intangibles, except developed technology, in November of 2014. 

Non-operating income (expense), net 

Non-operating income (expense), net, decreased by $250,000 to expense of $181,000 for the year ended December 31, 
2015 from income of $69,000 for the year ended December 31, 2014. The decrease was due to lower interest income of 
$187,000;  higher  interest  expense  of  $42,000;  unfavorable  fair  value  remeasurement  of  put  foreign  currency  options  of 
$58,000; and favorable foreign currency exchange of $37,000 compared to the prior period. 

Income taxes 

The income tax benefit was $0.3 million for the year ended December 31, 2015 compared to a tax provision of $0.3 
million  for  the  year  ended  December  31,  2014.  The  tax  benefit  of  $0.3  million  for  the  year  ended  December  31,  2015, 
consisted of $0.6 million benefit related to the losses in our Ireland subsidiary. The benefit was offset by tax expense of $0.3 
million related to the deferred tax effects associated with the amortization of goodwill and other taxes.  

The tax provision of $0.3 million for the year ended December 31, 2014, consisted of tax expense of $0.3 million related 
to the deferred tax effects associated with the amortization of goodwill and state and other taxes. The tax expenses were offset 
by a tax benefit associated with foreign currency translation adjustments recorded in other comprehensive income.

For the Year Ended December 31, 

Product revenue decreased by $12.6 million, or 29%, to $30.4 million for the year ended December 31, 2014 from $43.0 
million for the year ended December 31, 2013. The decrease in revenue was primarily due to significantly lower mega-project 
(MPD) shipments in 2014 compared to 2013 as well as lower OEM shipments. Of the $12.6 million decrease in revenue, 
$13.2 million related to Water MPD sales and $1.9 million related to Water OEM sales. The decreases were offset by $1.7 
million of higher Water aftermarket shipments and $0.8 million of revenue attributable to an Oil & Gas operating lease and 
lease buy-out. 

Revenue by product category and as a percentage of product revenue was as follows:

60% 

For the year ended December 31, 2014, gross profit as a percentage of product revenue was 55% compared to 60% for 

the year ended December 31, 2013.  

The decrease in product gross profit as a percentage of product revenue in 2014 compared to 2013 was primarily due to 
lower production volume and a shift in product mix toward turbochargers and pumps. The shift in product mix caused a 
decrease in total gross profit as turbochargers and pumps have a lower gross profit margin compared to PX devices.  

Manufacturing headcount decreased to 38 for the year ended December 31, 2014 from 45 for the year ended December 

31, 2013. 

Stock-based compensation expense included in cost of revenue was $101,000 for the year ended December 31, 2014 and 

$74,000 for the year ended December 31, 2013. 

General and administrative  

General and administrative expense decreased by $1.1 million, or 7%, to $14.1 million for the year ended December 31, 
2014  from  $15.2  million  for  the  year  ended  December  31,  2013.  General  and administrative  expense  as  a  percentage  of 
product revenue increased to 46% for the year ended December 31, 2014 compared to 35% for the year ended December 31, 
2013 primarily due to lower product revenue period over period. 

Of the $1.1 million net decrease in general and administrative expense, $1.8 million primarily related to compensation 
and employee-related benefits associated with the redeployment of personnel to oil & gas development; $0.9 million related 
to the reversal of VAT expensed in 2011 and prior for which we subsequently sought recovery and a refund was received 
from the Spanish authorities during 2014; $0.2 million related to the fair value remeasurement of the contingent consideration 
settled in 2014; and $0.2 million related to bad debt expense, occupancy costs, and other taxes. Offsetting the decreases was 
an  increase  of  $2.0  million  related  to  professional,  legal,  and  other  administrative  costs,  including  that  related  to  the 
termination of the former Senior Vice-President of Sales. 

General and administrative headcount increased to 28 for the year ended December 31, 2014 from 27 for the year ended 

December 31, 2013.  

Stock-based compensation expense included in general and administrative expense was $1.2 million for the year ended 

December 31, 2014 and $1.5 million for the year ended December 31, 2013. 

Sales and marketing  

Sales and marketing expense increased by $2.6 million, or 32%, to $10.5 million for the year ended December 31, 2014 
from $8.0 million for the year ended December 31, 2013. Sales and marketing expense as a percentage of product revenue 
increased to 35% for the year ended December 31, 2014 from 18% for the year ended December 31, 2013, primarily due to 
higher sales and marketing expense and lower product revenue period over period. 

Of the $2.6 million net increase in sales and marketing expense, $2.0 million related to compensation and employee-
related benefits related to increased headcount including those redeployed from general and administrative and $1.1 million 
related to marketing, professional, occupancy, and other sales and marketing costs. The increases were offset by a decrease 
of $0.5 million related to sales commissions. 

Sales  and  marketing  headcount  increased  to  36  for  the  year  ended  December  31,  2014  from  26  for  the  year  ended 

December 31, 2013. 

Stock-based compensation expense included in sales and marketing expense was $487,000 for the year ended December 

31, 2014 and $424,000 for the year ended December 31, 2013.

Research and development  

Research and development expense increased by $5.3 million, or 122%, to $9.7 million for the year ended December 
31, 2014 from $4.4 million for the year ended December 31, 2013. Research and development expense as a percentage of 
product revenue increased to 32% for the year ended December 31, 2014 from 10% for the year ended December 31, 2013, 
primarily due to increased research and development costs and lower product revenue period over period. 

Of  the  $5.3  million  increase  in  research  and  development  expense,  $4.4  million  related  to  direct  research  and 
development project costs associated with new product initiatives, $0.7 million related to compensation, employee-related 
benefits, and occupancy costs, and $0.2 million related to consulting and professional services.  

Research and development headcount increased to 22 for the year ended December 31, 2014 from 14 for the year ended 

December 31, 2013.  

Stock-based  compensation  expense  included  in  research  and  development  expense  was  $342,000  for  the  year  ended 

December 31, 2014 and $197,000 for the year ended December 31, 2013. 

Amortization of intangible assets 

Amortization expense decreased by $79,000, or 9%, to $0.8 million for the year ended December 31, 2014 from $0.9 
million for the year ended December 31, 2013. The decrease was due to a $66,000 decrease in the amortization amount for 
customer  relationships  related  to  the  sum-of-the-years-digits  amortization  calculation  and  $13,000  related  to  the  full 
amortization of all intangibles, except developed technology, in November of 2014. 

Restructuring charges 

The  decrease  in  restructuring  charges  was  due  to  the  sale  of  the  final  asset  associated  with  the  restructuring  plan  to 
consolidate our North American production activity being completed in September 2013. Net proceeds from the sale totaled 
$1.2 million, resulting in a loss on sale for these assets of $140,000, which was recorded in restructuring charges during the 
year  ended  December  31,  2013.  Additional  restructuring  charges  during  the  year  ended  December  31,  2013  included  an 
impairment  loss  on  assets  held  for  sale  of  $44,000  to  reflect  the  market  value  of  the  land  and  building.  There  were  no 
restructuring charges in 2014. 

Non-operating income (expense), net 

Non-operating income (expense), net, decreased by $40,000 to income of $69,000 for the year ended December 31, 2014 
from income of $109,000 for the year ended December 31, 2013. The decrease was due to $147,000 of unfavorable impacts 
from net foreign currency losses offset by higher interest and other income of $107,000 compared to the prior period. 

Income taxes 

The income tax provision was $0.3 million for both the year ended December 31, 2014 and for the year ended December 
31, 2013. The tax provision of $0.3 million for the year ended December 31, 2014, consisted of tax expense of $317,000 
related to the deferred tax effects associated with the amortization of goodwill and $17,000 related to state and other taxes. 
The tax expenses were offset by $42,000 of tax benefit associated with foreign currency translation adjustments recorded in 
other comprehensive income. 

The tax provision of $0.3 million for the year ended December 31, 2013, consisted of tax expense of $227,000 related 
to the deferred tax effects associated with the amortization of goodwill, $97,000 related to our federal tax to actual provision 
adjustment, and $3,000 of state and other taxes.

Liquidity and Capital Resources 

Historically, our primary sources of cash are proceeds from the issuance of common stock and customer payments for 
our products and services. From January 1, 2005 through December 31, 2015, we issued common stock for aggregate net 
proceeds of $88.2 million, excluding common stock issued in exchange for promissory notes. The proceeds from the sales of 
common stock have been used to fund our operations and capital expenditures. In October 2015, we received a payment of 
$75 million for an exclusive license to our VorTeq hydraulic fracturing system. 

As of December 31, 2015, our principal sources of liquidity consisted of unrestricted cash and cash equivalents of $99.9 
million,  some  of  which  is  invested  in  money  market  funds;  short-term  investments  in  marketable  debt  securities  of  $0.3 
million; and accounts receivable of $11.6 million. We generally invest cash not needed for current operations predominantly 
in high-quality, investment-grade, and marketable debt instruments with the intent to make such funds available for operating 
purposes as needed. 

We currently have unbilled receivables pertaining to customer contractual holdback provisions, whereby we will invoice 
the final retention payment(s) due under certain sales contracts in the next 2 to 31 months. The customer holdbacks represent 
amounts intended to provide a form of security for the customer; accordingly, these receivables have not been discounted to 
present value. At December 31, 2015 and 2014, we had $1.9 million and $1.8 million, respectively, of short-term and long-
term unbilled receivables.  

In 2009, we entered into a loan and security agreement (the “2009 Agreement”) with a financial institution. The 2009 
Agreement, as amended, provided a total available credit line of $16.0 million. Under the 2009 Agreement, we were allowed 
to draw advances of up to $10.0 million on a revolving line of credit or utilize up to $15.9 million as collateral for stand-by 
letters of credit, provided that the aggregate of the outstanding advances and collateral did not exceed the total available credit 
line of $16.0 million. Any advances under the revolving line of credit would incur interest based on a prime rate index or on 
LIBOR plus 1.375%. 

During the periods presented, we provided certain customers with stand-by letters of credit to secure our obligations for 
the delivery and performance of products in accordance with sales arrangements. Some of these stand-by letters of credit 
were  issued  under  our  2009  Agreement.  The  stand-by  letters  of  credit  generally  terminate  within  12  to  48  months  from 
issuance.  As  of  December  31,  2015,  the  amount  outstanding  on  stand-by  letters  of  credit  collateralized  under  our  2009 
Agreement totaled was $0. 

The 2009 Agreement, as amended, required us to maintain a cash collateral balance equal to at least 101% of the face 
amount  of  all  outstanding  stand-by  letters  of  credit  collateralized  by  the  line  of  credit  and  100%  of  the  amount  of  all 
outstanding advances. The 2009 Agreement expired at the end of May 2012. Once the 2009 Agreement expired, we were 
required to maintain a cash collateral balance equal to at least 105% of the face amount of all outstanding stand-by letters of 
credit collateralized by the line of credit and 100% of the amount of all outstanding advances. There were no advances drawn 
on the line of credit under the 2009 Agreement at the time of its expiration. As of December 31, 2015, restricted cash related 
to the remaining stand-by letters of credit issued under the 2009 Agreement was $0. 

On  June  5,  2012,  we  entered  into  a  loan  and  security  agreement  (the  “2012  Agreement”)  with  another  financial 
institution. The 2012 Agreement provides for a total available credit line of $16.0 million. Under the 2012 Agreement, we 
are allowed to draw advances not to exceed, at any time, $10.0 million as revolving loans. The total stand-by letters of credit 
issued  under  the  2012  Agreement  may  not  exceed  the  lesser  of  the  $16.0  million  credit  line  or  the  credit  line  minus  all 
outstanding revolving loans. At no time may the aggregate of the revolving loans and stand-by letters of credit exceed the 
total available credit line of $16.0 million. Revolving loans may be in the form of a base rate loan that bears interest equal to 
the prime rate plus 0% or a Eurodollar loan that bears interest equal to the adjusted LIBOR rate plus 1.25%. Stand-by letters 
of credit are subject to customary fees and expenses for issuance or renewal. The unused portion of the credit facility is 
subject to a facility fee in an amount equal to 0.25% per annum of the average unused portion of the revolving line. 

The 2012 Agreement requires us to maintain a cash collateral balance equal to 101% of all outstanding advances and all 
outstanding stand-by letters of credit collateralized by the line of credit. The 2012 Agreement matures on June 5, 2015 and 
is collateralized by substantially all of our assets. There were no advances drawn under the 2012 Agreement’s line of credit 
as of December 31, 2015. As of December 31, 2015, the amount outstanding on stand-by letters of credit collateralized under 
the 2012 Agreement totaled $3.8 million, and restricted cash related to the stand-by letters of credit issued under the 2012 
Agreement was $3.8 million. Of the $3.8 million cash restricted, $1.5 million was classified as current and $2.3 million was 
classified as non-current.

Cash Flows from Operating Activities 

Net cash provided by (used in) operating activities was $69.1 million, $(3.7) million, and $2.1 million for the years ended 
December 31, 2015, 2014, and 2013, respectively. For the years ended December 31, 2015, 2014, and 2013, net losses of 
$(11.6) million, $(18.7) million, and $(3.1) million, respectively, were adjusted to $(4.3) million, $(10.9) million, and $3.8 
million, respectively, by non-cash items totaling $7.3 million, $7.8 million, and $6.9 million, respectively. 

Non-cash adjustments in 2015 primarily included $ 4.1 million of stock-based compensation; $3.8 million of depreciation 
and amortization; $0.2 million of amortization of premiums paid on investments; a $0.1 million provision for warranty claims; 
$0.1 million of reserves for doubtful accounts; $(0.4) million reversal of accruals related to expired warranties; $(0.3) million 
of deferred income taxes; and $(0.3) million of valuation adjustments to excess and obsolete inventory reserves. 

Non-cash adjustments in 2014 primarily included $4.0 million of depreciation and amortization, $2.1 million of stock-
based  compensation,  $0.7  million  of  deferred  income  taxes  and  other  non-cash  items,  $0.4  million  of  amortization  of 
premiums paid on investments, $0.3 million of reserves for doubtful accounts, $0.3 million of valuation adjustments to excess 
and obsolete inventory reserves, a $0.2 million provision for warranty claims, $(0.2) million related to the change in fair 
value of a contingent consideration, and $(0.1) million of unrealized gains on foreign currency transactions. 

Non-cash adjustments in 2013 primarily included $3.8 million of depreciation and amortization, $2.2 million of stock-
based compensation, $0.4 million of amortization of premiums paid on investments, $0.3 million of valuation adjustments to 
excess and obsolete inventory reserves, $0.2 million of deferred income taxes, $0.2 million of restructuring charges related 
to the impairment of assets held for sale, a $0.1 million provision for warranty claims, and $(0.3) million of change in warranty 
reserve estimates. 

The net cash effect from changes in operating assets and liabilities was $73.3 million, $7.2 million and $(1.7) million for 
the years ended December 31, 2015, 2014, and 2013, respectively. Net changes in assets and liabilities in 2015 were primarily 
attributable to the receipt of a $75.0 million exclusive license payment, of which $1.0 million was recognized as revenue and 
the remainder deferred; $2.0 million decrease in inventories related to increased shipments; $0.3 million increase in product 
deferred  revenue;  and  $0.3  million  decrease  in  prepaid  expenses  and  other  assets.  These  were  offset  by  a  $(1.7)  million 
litigation settlement payment; a $(0.9) million increase in accounts receivable and unbilled receivables related to increased 
shipments;  and  $(0.7)  million  decrease  in  accrued  expenses  and  other  liabilities  related  to  decrease  legal  expenses  and 
litigation matters. 

Net changes in assets and liabilities in 2014 were primarily attributable to an $8.9 million decrease in accounts receivable 
and unbilled receivables as a result of lower sales and the collection of outstanding amounts, a $1.9 million increase in accrued 
expenses and other liabilities related to increased legal expense and litigation matters, and a $0.6 million increase in accounts 
payable due to the timing of payments to employees, vendors, and other third parties. These were offset by a $3.6 million 
increase in inventory of which $2.3 million was an increase in finished goods principally related to a large MPD shipment 
built in the fourth quarter of 2014 but expected to ship in the first quarter of 2015, a $0.3 increase in prepaid expenses, and a 
$0.3 million decrease in deferred revenue. 

Net changes in assets and liabilities in 2013 were primarily attributable to a $2.8 million increase in accounts receivable 
and unbilled receivables as a result of invoicing and collections for large projects; a $1.6 million decrease in accounts payable 
and accrued liabilities as a result of the timing of payments to employees, vendors, and other third parties; a $0.4 million 
decrease in deferred revenue; and a $0.1 million decrease in inventory as a result of order processing and product shipments, 
offset by a $3.2 million decrease in prepaid expenses as a result of the receipt of tax refunds. 

Cash Flows from Investing Activities 

Cash flows from investing activities primarily relate to maturities and purchases of marketable securities to preserve 
principal and liquidity while at the same time maximizing yields without significantly increasing risk, capital expenditures 
to  support  our  growth,  and  changes  in  our  restricted  cash  used  to  collateralize  our  stand-by  letters  of  credit  and  other 
contingent considerations.

Net cash provided by (used in) investing activities was $14.0 million, $6.5 million, and $(4.9) million for the years ended 
December  31,  2015,  2014,  and  2013,  respectively.  Cash  provided  in  2015  was  primarily  attributable  to  $12.9  million  in 
maturities of investments and the release of $1.7 million of restricted cash related to the expiration of SBLCs. These were 
offset by the use of $(0.6) million for capital expenditures. 

Cash provided in 2014 was primarily attributable to $6.0 million in maturities of investments and the release of $3.3 
million of restricted cash primarily related to the settlement of a contingent consideration. These were offset by uses of $(2.6) 
million for capital expenditures and a $(0.2) million purchase of additional investments. 

Cash used in 2013 was primarily attributable to $(15.3) million used to invest in marketable securities and $(1.1) million 
used for capital expenditures. These uses were offset by $9.6 million of maturities of investments, $1.2 million proceeds from 
the sale of property and equipment, and the release of $0.8 million of restricted cash primarily related to the maturing of 
stand-by letters of credit. 

Cash Flows from Financing Activities 

Net cash provided by (used in) financing activities was $1.4 million, $(1.8) million, and $0.5 million for the years ending 
December 31, 2015, 2014, and 2013, respectively. Net cash provided in 2015 was primarily due to $1.3 million received 
from the issuance of common stock related to option and warrant exercises and $0.1 million of proceeds from long-term debt.  

Net cash used in 2014 was primarily due to the use of $2.8 million to repurchase our common stock and $1.4 million to 
pay a contingent consideration. These uses were offset by $2.4 million received from the issuance of common stock related 
to option and warrant exercises.  

Net cash provided in 2013 was primarily due to $0.5 million of cash received from the issuance of common stock related 

to option and warrant exercises. 

Liquidity and Capital Resource Requirements 

We believe that our existing resources and cash generated from our operations will be sufficient to meet our anticipated 
capital requirements for at least the next twelve months. However, we may need to raise additional capital or incur additional 
indebtedness to continue to fund our operations or to support acquisitions in the future. Our future capital requirements will 
depend on many factors, including our rate of revenue growth, if any, the expansion of our sales and marketing and research 
and development activities, the amount and timing of cash used for stock repurchases, the timing and extent of our expansion 
into  new  geographic  territories,  the  timing  of  new  product  introductions,  and  the  continuing  market  acceptance  of  our 
products. We may enter into potential material investments in, or acquisitions of, complementary businesses, services, or 
technologies in the future, which could also require us to seek additional equity or debt financing. Additional funds may not 
be available on terms favorable to us or at all. 

Contractual Obligations 

We lease facilities and equipment under fixed non-cancellable operating leases that expire on various dates through 2019. 
Additionally,  in  the  course  of  our  normal  operations,  we  have  entered  into  cancellable  purchase  commitments  with  our 
suppliers for various key raw materials and component parts. The purchase commitments covered by these arrangements are 
subject to change based on our sales forecasts for future deliveries.

This table excludes agreements with guarantees or indemnity provisions that we have entered into with customers and 
others in the ordinary course of business. Based on our historical experience and information known to us as of December 
31, 2015, we believe that our exposure related to these guarantees and indemnities as of December 31, 2015 was not material.  

Off-Balance Sheet Arrangements 

During the periods presented, we did not have any relationships with unconsolidated entities or financial partnerships 
such as entities often referred to as structured finance or special purpose entities, which would have been established for the 
purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.

Item 7A — Quantitative and Qualitative Disclosures About Market Risk 

Foreign Currency Risk 

The majority of our revenue contracts have been denominated in United States Dollars (“USD”). In some circumstances, 
we have priced certain international sales in Euros. The amount of revenue recognized and denominated in Euros amounted 
to $11,000, $0.9 million, and $39,000 in 2015, 2014, and 2013, respectively. We experienced a net foreign currency loss of 
approximately $119,000, $18,000, and $3,000, related to our revenue contracts for the years ended December 31, 2015, 2014, 
and 2013, respectively. Of the $119,000 of foreign currency losses in 2015, $106,000 related to revenue recognized in 2014, 
but collected in 2015. 

In 2015, we entered into a sales contract denominated in Euros to be paid in three milestone payments over the next two 
years. As a result of this transaction, we purchased three foreign-currency put options to offset the downside foreign exchange 
risk associated with the corresponding sale. For future sales denominated in non U.S. currency, we are likely to enter into 
similar arrangements. 

As we expand our international sales, we expect that a portion of our revenue could continue to be denominated in foreign 
currencies. As a result, our cash and cash equivalents and operating results could be increasingly affected by changes in 
exchange rates. Our international sales and marketing operations incur expense that is denominated in foreign currencies. 
This expense could be materially affected by currency fluctuations. Our exposures are to fluctuations in exchange rates for 
USD versus the Euro, AED, CNY, and CAD. Changes in currency exchange rates could adversely affect our consolidated 
operating results or financial position. Additionally, our international sales and marketing operations maintain cash balances 
denominated in foreign currencies. To decrease the inherent risk associated with translation of foreign cash balances into our 
reporting currency, we do not  maintain excess cash balances in foreign currencies. We have not hedged our exposure to 
changes  in  foreign  currency  exchange  rates  because  expenses  in  foreign  currencies  have  been  insignificant  to  date,  and 
exchange rate fluctuations have had little impact on our operating results and cash flows. 

Interest Rate Risk and Credit Risk 

We  have  an  investment  portfolio  of  fixed  income  marketable  debt  securities,  including  amounts  classified  as  cash 
equivalents, short-term investments, and long-term investments. At December 31, 2015, all of our investments were classified 
as  short-term  and  totaled  approximately  $0.3  million.  The  primary  objective  of  our  investment  activities  is  to  preserve 
principal and liquidity while at the same time maximizing yields without significantly increasing risk. We invest primarily 
in high-quality short-term and long-term debt instruments of the U.S. government and its agencies as well as high-quality 
corporate issuers. These investments are subject to interest rate fluctuations and will decrease in market value if interest rates 
increase. To minimize the exposure due to adverse shifts in interest rates, we maintain investments with an average maturity 
of  less  than  eighteen  (18)  months. A  hypothetical  1%  increase  in  interest  rates  would have resulted  in  an  approximately 
$1,000 decrease in the fair value of our fixed-income debt securities as of December 31, 2015. 

In addition to interest rate risk, our investments in marketable debt securities are subject to potential loss of value due to 
counterparty  credit  risk.  To  minimize  this  risk,  we  invest  pursuant  to  a  Board-approved  investment  policy.  The  policy 
mandates high credit rating requirements and restricts our exposure to any single corporate issuer by imposing concentration 
limits.

Item 8 — Financial Statements and Supplementary Data 

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

The Board of Directors and Stockholders 
Energy Recovery, Inc. 
San Leandro, California 

We have audited the accompanying consolidated balance sheets of Energy Recovery, Inc. as of December 31, 2015 and 
2014 and the related consolidated statements of operations, comprehensive loss, stockholders’ equity, and cash flows for 
each of the three years in the period ended December 31, 2015. In connection with our audits of the financial statements, we 
have  also  audited  the  financial  statement  schedule  (“schedule”)  listed  in  Item  15(a)(2).  These  financial  statements  and 
schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial 
statements and schedule based on our audits. 

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United 
States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial 
statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts 
and  disclosures  in  the  financial  statements,  assessing  the  accounting  principles  used  and  significant  estimates  made  by 
management, as well as evaluating the overall presentation of the financial statements and schedule. We believe that our 
audits provide a reasonable basis for our opinion. 

In  our  opinion,  the  Consolidated  Financial  Statements  referred  to  above  present  fairly,  in  all  material  respects,  the 
financial position of Energy Recovery, Inc. at December 31, 2015 and 2014, and the results of its operations and its cash 
flows for each of the three years in the period ended December 31, 2015, in conformity with accounting principles generally 
accepted in the United States of America. 

Also, in our opinion, the financial statement schedule, when considered in relation to the basic Consolidated Financial 

Statements taken as a whole, presents fairly, in all material respects, the information set forth therein. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States),  Energy  Recovery,  Inc.’s  internal  control  over  financial  reporting  as  of  December  31,  2015,  based  on  criteria 
established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of 
the Treadway Commission (COSO) and our report dated March 3, 2016 expressed an unqualified opinion thereon.

Our Consolidated Financial Statements include the accounts of Energy Recovery, Inc. and its wholly-owned subsidiaries. 

All significant intercompany accounts and transactions have been eliminated in consolidation. 

Use of Estimates 

The preparation of Consolidated Financial Statements in conformity with U.S. generally accepted accounting principles 
(“U.S. GAAP”) requires our management to make judgments, assumptions, and estimates that affect the amounts reported in 
our Consolidated Financial Statements and accompanying Notes. The accounting policies that reflect our more significant 
estimates and judgments and that we believe are the most critical to aid in fully understanding and evaluating our reported 
financial results are revenue recognition; allowance for doubtful accounts; allowance for product warranty; valuation of stock 
options; valuation and impairment of goodwill and acquired intangible assets; useful lives for depreciation and amortization; 
valuation adjustments for excess and obsolete inventory; deferred taxes and valuation allowances on deferred tax assets; and 
evaluation and measurement of contingencies, including contingent consideration. Those estimates could change, and as a 
result, actual results could differ materially from those estimates. For example, the Company records impairment losses on 
long-lived assets used in operations when events and circumstances indicate that long-lived assets might be impaired and the 
undiscounted cash flows estimated to be generated by those assets are less than the carrying amounts of those assets. The 
Company’s estimate of undiscounted cash flows, at December 31, 2015 and 2014 indicated that such carrying amounts were 
expected to be recovered. Nonetheless, it is possible that the estimate of undiscounted cash flows may change in the future 
resulting in the need to write down those assets to fair value. 

Change in Accounting Principle for Goodwill Impairment Testing 

In 2014 and prior, we evaluated our goodwill for impairment at the reporting unit level annually during the fourth quarter 
or when indicators for potential impairment were present. At that time we operated under a single reporting unit. On July 1, 
2015, we adopted a new organizational and reporting structure based on the operating segments, Water and Oil & Gas. We 
have reassessed our reporting units and the impairment analysis of goodwill and long-lived assets, and performed our analysis 
based  on  the  new  structure.  During  the  third  quarter  of  2015,  we  changed  the  measurement  date  of  our  annual  goodwill 
impairment test from the fourth quarter to July 1. This change was not material to our Consolidated Financial Statements as 
it did not result in the delay, acceleration, or avoidance of an impairment charge. We believe the new timing better aligns the 
goodwill impairment test with our strategic business planning process, which is a key component of the goodwill impairment 
test. We completed the required annual testing of goodwill for all reporting units as of July 1, 2015, as well as reassessing at 
December 31, 2015, and have determined that goodwill is not impaired. 

Cash and Cash Equivalents 

We consider all highly liquid investments with an original or remaining maturity of three months or less at the time of 
purchase  to  be  cash  equivalents.  Cash  equivalents  are  stated  at  cost,  which  approximates  fair  value.  Our  cash  and  cash 
equivalents are maintained primarily in demand deposit accounts with large financial institutions and in institutional money 
market funds. We frequently monitor the creditworthiness of the financial institutions and institutional money market funds 
in which we invest our surplus funds. We have not experienced any credit losses from our cash investments.

Allowances for Doubtful Accounts 

We record a provision for doubtful accounts based on historical experience and a detailed assessment of the collectability 
of our accounts receivable. In estimating the allowance for doubtful accounts, we consider, among other factors, the aging of 
the accounts receivable, our historical write-offs, the credit worthiness of each customer, and general economic conditions. 
Account balances are charged off against the allowance when we believe that it is probable that the receivable will not be 
recovered. Actual write-offs may be in excess of our estimated allowance. 

Short-Term and Long-Term Investments 

Our  short-term  and  long-term  investments  consist  primarily  of  investment-grade  debt  securities,  all  of  which  are 
classified as available-for-sale. Available-for-sale securities are carried at fair value. Amortization or accretion of premium 
or discount is included in other income (expense) on the Consolidated Statements of Operations. Changes in the fair value of 
available-for-sale  securities  are  reported  as  a  component  of  accumulated  other  comprehensive  loss  within  stockholders’ 
equity on the Consolidated Balance Sheet. Realized gains and losses on the sale of available-for-sale securities are determined 
by specific identification of the cost basis of each security. Long-term investments generally will mature within three (3) 
years. 

Inventories 

Inventories are stated at the lower of cost (using the first-in, first-out “FIFO” method) or market. We calculate inventory 
valuation adjustments for excess and obsolete inventory based on current inventory levels, movement, expected useful lives, 
and estimated future demand of the products and spare parts. 

Property and Equipment 

Property and equipment is recorded at cost and reduced by accumulated depreciation. Depreciation expense is recognized 
over  the  estimated  useful  lives  of  the  assets  using  the straight-line  method.  Estimated  useful  lives  are  three  to  ten  years. 
Certain equipment used in the development and manufacturing of ceramic components is depreciated over estimated useful 
lives  of  up  to  ten  years.  Leasehold  improvements  represent  remodeling  and  retrofitting  costs  for  leased  office  and 
manufacturing space and are depreciated over the shorter of either the estimated useful lives or the term of the lease. Software 
purchased for internal use consists primarily of amounts paid for perpetual licenses to third-party software providers and 
installation costs. Software is depreciated over the estimated useful lives of three (3) to five (5) years. Estimated useful lives 
are  periodically  reviewed,  and  when  appropriate,  changes  are  made  prospectively.  When  certain  events  or  changes  in 
operating conditions occur, asset lives may be adjusted and an impairment assessment may be performed on the recoverability 
of the carrying amounts. Maintenance and repairs are charged directly to expense as incurred. 

We previously owned our manufacturing facility in New Boston, Michigan. As a result of the consolidation of our North 
American manufacturing operations, amounts related to the building and land were classified as held for sale at December 
31,  2011. Accordingly,  we  impaired  the  building  and  land held  for  sale  by  $728,000  and  ceased  depreciation  charges  in 
December 2011. We recorded an additional $44,000 and $314,000 of impairment charges during the years ended December 
31, 2013 and 2012, respectively, to reduce the carrying value to the estimated fair value. The property was sold in September 
2013. Net proceeds from the sale totaled $1.2 million, resulting in a loss on sale of $0.1 million. 

Goodwill and Other Intangible Assets 

The  purchase  price  of  an  acquired  company  is  allocated  between  intangible  assets  and  the  net  tangible  assets  of  the 
acquired business with the residual purchase price recorded as goodwill. The determination of the value of the intangible 
assets acquired involves certain judgments and estimates. These judgments can include, but are not limited to, the cash flows 
that an asset is expected to generate in the future and the appropriate weighted average cost of capital. 

Acquired intangible assets with determinable useful lives are amortized on a straight-line or accelerated basis over the 
estimated periods benefited, ranging from one to 20 years. Acquired intangible assets with contractual terms are amortized 
over  their  respective  legal  or  contractual  lives.  Customer  relationships  and  other  non-contractual  intangible  assets  with 
determinable lives are amortized over periods ranging from five to 20 years.  

-49- 

  
  
  
  
  
  
  
  
  
  
  
   
 
 
We evaluate the recoverability of intangible assets by comparing the carrying amount of an asset to estimated future net 
undiscounted cash flows generated by the asset. If such assets are considered to be impaired, the impairment recognized is 
measured as the amount by which the carrying amount of the assets exceeds the fair value of the assets. The evaluation of 
recoverability involves estimates of future operating cash flows based upon certain forecasted assumptions, including, but 
not limited to, revenue growth rates, gross profit margins, and operating expenses over the expected remaining useful life of 
the related asset. A shortfall in these estimated operating cash flows could result in an impairment charge in the future. 

Goodwill is not amortized, but is evaluated annually for impairment at the reporting unit level or when indicators of a 
potential impairment are present. We estimate the fair value of the reporting unit using the discounted cash flow and market 
approaches. Forecast of future cash flows are based on our best estimate of future net sales and operating expenses, based 
primarily on expected category expansion, pricing, market segment, and general economic conditions.  

As  of  December  31,  2015  and  2014,  acquired  intangibles,  including  goodwill,  relate  to  the  acquisition  of  Pump 
Engineering, LLC during the fourth quarter of 2009. See Note 6 — “Goodwill and Intangible Assets” for further discussion 
of intangible assets. 

Fair Value of Financial Instruments 

Our  financial  instruments  include  cash  and  cash  equivalents,  restricted  cash,  investments  in  marketable  securities, 
accounts  receivable,  accounts  payable,  and  debt.  The  carrying  amounts  for  these  financial  instruments  reported  in  the 
Consolidated Balance Sheets approximate their fair values. See Note 7 — “Fair Value Measurements” for further discussion 
of fair value. 

Revenue Recognition  

Product revenue recognition 

We recognize revenue when the earnings process is complete, as evidenced by a written agreement with the customer, 
transfer of title, fixed pricing that is determinable, and collection that is reasonably assured. Transfer of title typically occurs 
upon shipment of the equipment pursuant to a written purchase order or contract. The portion of the sales agreement related 
to the field services and training for commissioning of our devices in a desalination plant is deferred until we have performed 
such  services.  We  regularly  evaluate  our  revenue  arrangements  to  identify  deliverables  and  to  determine  whether  these 
deliverables are separable into multiple units of accounting.  

Under our revenue recognition policy, evidence of an arrangement has been met when we have an executed purchase 
order, sales order, or stand-alone contract. Typically, smaller projects utilize sales or purchase orders that conform to standard 
terms and conditions. 

The specified product performance criteria for our PX device pertain to the ability of our product to meet its published 
performance specifications and warranty provisions, which our products have demonstrated on a consistent basis. This factor, 
combined with historical performance metrics, provides our management with a reasonable basis to conclude that its PX 
device  will  perform  satisfactorily  upon  commissioning  of  the  plant.  To  ensure  this  successful  product  performance,  we 
provide  service  consisting  principally  of  supervision  of  customer  personnel  and  training  to  the  customers  during  the 
commissioning of the plant. The installation of the PX device is relatively simple, requires no customization, and is performed 
by the customer under the supervision of our personnel. We defer the value of the service and training component of the 
contract and recognize such revenue as services are rendered. Based on these factors, our management has concluded that, 
for sale of PX devices, as well as for turbochargers and pumps, delivery and performance have been completed upon shipment 
or delivery when title transfers based on the shipping terms. 

We  perform  an  evaluation  of  credit  worthiness  on  an  individual  contract  basis  to  assess  whether  collectability  is 
reasonably  assured.  As  part  of  this  evaluation,  our  management  considers  many  factors  about  the  individual  customer, 
including the underlying financial strength of the customer and/or partnership consortium and management’s prior history or 
industry-specific knowledge about the customer and its supplier relationships. For smaller projects, we require the customer 
to  remit  payment  generally  within  30  to  90  days  after  product  delivery.  In  some  cases,  if  credit  worthiness  cannot  be 
determined, prepayment or other security is required from smaller customers. 

-50- 

  
  
  
  
  
  
  
  
  
  
   
 
 
We establish separate units of accounting for contracts, as our contracts with customers typically include one or both of 

the following deliverables, and there is no right of return under the terms of the contract. 

●  Products 
●  Commissioning  which  includes  supervision  of  the  installation,  start-up,  and  training  to  ensure  that  the
installation performed by the customer, which is relatively simple and straightforward, is completed consistent
with the recommendations under the factory warranty.  

The commissioning services’ element of our contracts represents an incidental portion of the total contract price. The 
allocable  consideration  for  these  services  relative  to  that  for  the  underlying  products  has  been  well  under  1%  of  any 
arrangement. Commissioning is often bundled into the large stand-alone contracts, and we frequently sell products without 
commissioning since our product can be easily installed in a plant without supervision. These facts and circumstances validate 
that the delivered element has value on a stand-alone basis and should be considered a separate unit of accounting. 

Having  established  separate  units  of  accounting,  we  then  take  the  next  steps  to  allocate  amounts  to  each  unit  of 
accounting. With respect to products, we have established vendor specific objective evidence (“VSOE”) based on the price 
at which such products are sold separately without commissioning services. With respect to commissioning, we charge out 
our engineers for field visits to customers based on a stand-alone standard daily field service charge as well as a flat service 
rate for travel, if applicable. This has been determined to be the VSOE of the service based on stand-alone sales of other 
comparable professional services at consistent pricing.  

The  amount  allocable  to  the  delivered  unit  of  account  (in  our  case  the  product)  is  limited  to  the  amount  that  is  not 
contingent upon the delivery of additional items or meeting specified performance conditions. We adhere to consistent pricing 
in both stand-alone sale of products and professional services and the contractual pricing of products and commissioning of 
services in bundled arrangements. 

For large projects, stand-alone contracts are utilized. For these contracts, consistent with industry practice, our customers 
typically require their suppliers, including Energy Recovery, to accept contractual holdback provisions (also referred to as a 
retention payment) whereby the final amounts due under the sales contract are remitted over extended periods of time or 
alternatively, stand-by letters of credit are issued to guarantee performance. These retention payments typically range between 
5%  and  15%,  of  the  total  contract  amount  and  are  due  and  payable  when  the  customer  is  satisfied  that  certain  specified 
product performance criteria have been met upon commissioning of the desalination plant, which may be up to 24 months 
from the date of product delivery as described further below. 

Under stand-alone contracts, the usual payment arrangements are summarized as follows: 

•  an advance payment due upon execution of the contract, typically 10% to 20% of the total contract amount. This advance
payment is accounted for as deferred revenue until shipment or when products are delivered to the customer, depending 
on the Incoterms and transfer of title; 

•  a payment ranging from 50% to 70% of the total contract is typically due upon delivery of the product. This payment is
often  divided  into  two  parts.  The  first  part,  which  is  due  30  to  60  days  following  delivery  of  the  product  and
documentation,  is  invoiced  upon  shipment  when  the  product  revenue  is  recognized  and  results  in  an  open  accounts
receivable  with  the  customer.  The  second  part  is  typically  due  90  to  120  days  following  product  delivery  and
documentation. This payment is booked to unbilled receivables upon shipment when the product revenue is recognized,
and it is invoiced to the customer upon notification that the equipment has been received or when the time period has
expired. We have no performance obligation to complete to be legally entitled to this payment. It is invoiced based on
the passage of time. 

•  a  final  retention  payment  of  usually  5%  to  15%  of  the  contract  amount  is  due  either  at  the  completion  of  plant
commissioning or upon the issuance of a stand-by letter of credit, which is typically issued up to 24 months from the
delivery date of products and documentation. This payment is recorded to unbilled receivables upon shipment when the
product revenue is recognized, and it is invoiced to the customer when it is determined that commissioning is complete
or the stand-by letter of credit has been issued. This payment is not contingent upon the delivery of commissioning
services. The Company had no performance obligation to complete to be legally entitled to this payment. It is invoiced
based on the passage of time.

We do not provide our customers with a right of product return; however, we will accept returns of products that are 
deemed to be damaged or defective when delivered that are covered by the terms and conditions of the product warranty. 
Product returns have not been significant. 

Shipping and handling charges billed to customers are included in product revenue. The cost of shipping to customers is 

included in cost of revenue. 

License and development revenue recognition 

License  revenue  is  comprised  of  fees  received  in  connection  the  Schlumberger  License  Agreement.  See  Note  16  – 
Schlumberger License Agreement. The agreement comprises a 15 year exclusive license for the our VorTeq technology, 
development services to commercialize the technology, support services, and, in the event commercialization is successful, 
supply  and  servicing  of  certain  components  of  the  VorTeq  and  development  services  related  to  integration  of  the 
commercialized technology with future Schlumberger equipment. Various types of payments to the Company are provided 
in  the  agreement,  including  an  upfront  exclusive  license  fee,  developmental  milestones,  and  payments  for  supply  and 
servicing of components subsequent to commercialization. All payments are non-refundable.  

We recognize license revenue in accordance with ASC 605 “Revenue Recognition”, subtopic ASC 605-25 “ Revenue 
with  Multiple  Element  Arrangements  ”  and  subtopic  ASC  605-28  “  Revenue  Recognition-Milestone  Method  ”,  which 
provides accounting guidance for revenue recognition for arrangements with multiple deliverables and guidance on defining 
the milestone and determining when the use of the milestone method of revenue recognition for research and development 
transactions is appropriate, respectively. 

For  multiple-element  arrangements,  each  deliverable  is  accounted  for  as  a  separate  unit  of  accounting  if  both  the 
following criteria are met: (1) the delivered item or items have value to the customer on a standalone basis and (2) for an 
arrangement that includes a general right of return relative to the delivered item(s), delivery or performance of the undelivered 
item(s) is considered probable and substantially in our control. Contingent deliverables within multiple element arrangements 
are excluded from the evaluation of the units of accounting. Non-refundable, upfront license fees where we have continuing 
obligation to perform are recognized over the period of the continuing performance obligation. The Schlumberger License 
Agreement was determined to include a single unit of accounting comprising the license, research and development, and 
support services. The initial upfront fee of $75 million will be recognized on a straight-line basis over the fifteen year term 
of the arrangement based on the performance period of the last or final deliverables, which include the license and support. 

We recognize revenue from milestone payments when: (i) the milestone event is substantive and its achievability has 
substantive uncertainty at the inception of the agreement, and (ii) it does not have ongoing performance obligations related 
to the achievement of the milestone earned. Milestone payments are considered substantive if all of the following conditions 
are met, the milestone payment: (a) is commensurate with either the Company’s performance subsequent to the inception of 
the arrangement to achieve the milestone or the enhancement of the value of the delivered item or items as a result of a 
specific outcome resulting from the Company’s performance subsequent to the inception of the arrangement to achieve the 
milestone; (b) relates solely to past performance; and (c) is reasonable relative to all of the deliverables and payment terms 
(including other potential milestone consideration) within the arrangement. The Schlumberger License Agreement includes 
two substantive milestones of $25 million each due on achieving specified development milestones. No revenues associated 
with achievement of the milestones have been recognized to date. 

Research and Development Expense 

Research  and  development  expenses  consist  of  costs  incurred  for  internal  projects  and  research  and  development 
activities performed for technology licensed to third parties. These costs include our direct and research-related overhead 
expenses, which include salaries and other personnel-related expenses (including stock-based compensation), occupancy-
related costs, depreciation of facilities, as well as external costs, and are expensed as incurred. Costs to acquire technologies 
that are utilized in research and development and that have no alternative future use are expensed when incurred.

Warranty Costs 

We sell products with a limited warranty for a period ranging from eighteen (18) months to five (5) years. We accrue for 
warranty costs based on estimated product failure rates, historical activity, and expectations of future costs. Periodically, we 
evaluate and adjust the warranty costs to the extent that actual warranty costs vary from the original estimates. 

During the year ended December 31, 2015, we adjusted previously established warranty reserves. The adjustment related 

to expired warranties which increased gross profit and reduced net loss by $0.4 million. 

During the year ended December 31, 2013, the Company adjusted previously established warranty reserves. The accruals 
had been made based on historic warranty claim rates during 2010 and 2011, a period that covered the integration of the PEI 
acquisition  and  related  manufacturing  operations  into  the  Company’s  existing  operation.  At  December  31,  2013,  the 
Company revised the rates based on warranty claim data during the two-year period after integration, which covered 2012 
and 2013. This resulted in a release of accruals related to expired warranties, which increased gross profit and reduced net 
loss by $0.3 million. 

Stock-based Compensation 

We measure and recognize stock-based compensation expense based on the fair value measurement for all stock-based 
awards  made  to  our  employees  and  directors  —  including  restricted  stock  units  (“RSUs”),  restricted  shares  (“RS”),  and 
employee stock options — over the requisite service period (typically the vesting period of the awards). The fair value of 
RSUs and RS is based on our stock price on the date of grant. At December 31, 2015, there were no outstanding RSUs or 
RS. The fair value of stock options is calculated on the date of grant using the Black-Scholes option pricing model, which 
requires a number of complex assumptions including expected life, expected volatility, risk-free interest rate, and dividend 
yield. The estimation of awards that will ultimately vest requires judgment, and to the extent that actual results or updated 
estimates differ from our current estimates, such amounts are recorded as a cumulative adjustment in the period in which the 
estimates are revised. See Note 12 — “Stock-based Compensation” for further discussion of stock-based compensation. 

Foreign Currency 

Our reporting currency is the U.S. dollar. The functional currency of our Ireland subsidiaries is the U.S. dollar, while the 
functional currency of our other foreign subsidiaries is their respective local currencies. The asset and liability accounts of 
our foreign subsidiaries are translated from their local currencies at the rates in effect on the balance sheet date. Revenue and 
expenses  are  translated  at  average  rates  of  exchange  prevailing  during  the  period.  Gains  and  losses  resulting  from  the 
translation of our subsidiary balance sheets are recorded as a component of accumulated other comprehensive loss. Gains 
and  losses  from  foreign  currency  transactions  are  recorded  in  other  income  (expense)  in  the  Consolidated  Statements  of 
Operations.  

Income Taxes 

Current and non-current tax assets and liabilities are based upon an estimate of taxes refundable or payable for each of 
the jurisdictions in which we are subject to tax. In the ordinary course of business, there is inherent uncertainty in quantifying 
income tax positions. We assess income tax positions and record tax benefits for all years subject to examination based upon 
our evaluation of the facts, circumstances, and information available at the reporting dates. For those tax positions where it 
is more likely than not that a tax benefit will be sustained, we record the largest amount of tax benefit with a greater than 
50% likelihood of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant 
information. For those income tax positions where it is not more likely than not that a tax benefit will be sustained, no tax 
benefit  is  recognized  in  the  financial  statements.  When  applicable,  associated  interest  and  penalties  are  recognized  as  a 
component of income tax expense. Accrued interest and penalties are included within the related tax asset or liability on the 
Consolidated Balance Sheets. 

Deferred income taxes are provided for temporary differences arising from differences in bases of assets and liabilities 
for tax and financial reporting purposes. Deferred income taxes are recorded on temporary differences using enacted tax rates 
in effect for the year in which the temporary differences are expected to reverse. The effect of a change in tax rates on deferred 
tax assets and liabilities is recognized in income in the period that includes the enactment date. Deferred tax assets are reduced 
by  a  valuation  allowance when,  in  the  opinion of  management,  it  is  more  likely  than not  that  some  portion  or  all  of  the 
deferred  tax  assets  will  not  be  realized.  Significant  judgment  is  required  in  determining  whether  and  to  what  extent  any 
valuation allowance is needed on our deferred tax assets. In making such a determination, we consider all available positive 
and negative evidence including recent results of operations, scheduled reversals of deferred tax liabilities, projected future 

-53- 

  
  
  
  
  
  
  
  
  
  
income, and available tax planning strategies. As of December 31, 2015, we have a valuation allowance of approximately 
$21.4 million to reduce our deferred income tax assets to the amount expected to be realized. See Note 10 — “Income Taxes” 
for further discussion of the tax valuation allowance. 

Our operations are subject to income and transaction taxes in the U.S. and in foreign jurisdictions. Significant estimates 
and judgments are required in determining our worldwide provision for income taxes. Some of these estimates are based on 
interpretations of existing tax laws or regulations. The ultimate amount of tax liability may be uncertain as a result. 

Recent Accounting Pronouncements 

Other than as described below, no new accounting pronouncement issued or effective during the fiscal year has had or 

is expected to have a material impact on our Consolidated Financial Statements. 

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-
09, Revenue from Contracts with Customers. The amendment 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. ASU 2014-09 will replace most existing 
revenue  recognition  guidance  in  U.S.  GAAP  when  it  becomes  effective.  ASU  2014-09  is  effective  for  annual  reporting 
periods  beginning  after December  15,  2016,  including  interim  periods within  that  reporting period. On  July 9, 2015,  the 
FASB voted to approve a one-year deferral of the effective date of ASU 2014-09. Based on the FASB’s decision, ASU 2014-
09 will  apply  to  us for  annual  reporting  periods beginning after  December  15, 2017,  including  interim  reporting periods 
within annual reporting periods beginning after December 15, 2017. Additionally, the FASB decided to permit early adoption, 
but not before the original effective date (that is, annual periods beginning after December 15, 2016). The FASB issued ASU 
2015-14 in August 2015, formally deferring the effective date of ASU 2014-09 by one year. We expect to adopt this guidance 
as of January 1, 2018. ASU 2014-09 permits the use of either the retrospective or cumulative effect transition method. We 
are currently evaluating the effect that ASU 2014-09 will have on our financial statements and related disclosures. We have 
not yet selected a transition method nor have we determined the effect of the standard on our ongoing financial reporting. 

In January 2015, the FASB issued ASU 2015-01, Income Statement – Extraordinary and Unusual Items. ASU 2015-01 
eliminates from GAAP the concept of extraordinary items. As a result, an entity will no longer be required to separately 
present an extraordinary item on its statement of operations, net of tax, after income from continuing operations, or disclose 
income taxes and net income per share data applicable to an extraordinary item. However, ASU 2015-01 will still retain the 
presentation and disclosure guidance for items that are unusual in nature and occur infrequently. ASU 2015-01 is effective 
for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted 
provided the guidance is applied from the beginning of the fiscal year of adoption. We do not expect the adoption of this 
standard to have a material impact on our financial statements, absent any material transactions in future periods that would 
qualify for extraordinary item presentation under the prior guidance. 

In April 2015, the FASB issued ASU 2015-03, Interest – Imputation of Interest. ASU 2015-03 require that debt issuance 
costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount 
of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are 
not affected by the amendments in this update. For public entities, ASU 2015-03 is effective for fiscal years, and interim 
periods within those fiscal years, beginning after December 15, 2015. We do not expect the adoption of this standard to have 
a material impact on our financial statements. 

Also in April 2015, the FASB issued ASU 2015-05, Intangibles – Goodwill and Other- Internal-Use Software. ASU 
2015-05 provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud 
computing arrangement includes a software license, then the customer should account for the software license element of the 
arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a 
software license, the customer should account for the arrangement as a service contract. ASU 2015-05 does not change GAAP 
for customer’s accounting for service contracts. For public entities, ASU 2015-05 is effective for fiscal years, and interim 
periods within those fiscal years, beginning after December 15, 2015. We do not expect the adoption of this standard to have

In July 2015, the FASB issued ASU 2015-11, Inventory – Simplifying the Measurement of Inventory. ASU 2015-11 does 
not apply only to inventory that is measured using last-in, first-our (“LIFO”) or to the retail inventory method. ASU 2015-11 
applies to all other inventory, which includes inventory that is measured using first-in, first-out (“FIFO”) or average cost. 
ASU 2015-11 provides that inventory be measured at the lower of cost and net realizable value. Net realizable value is the 
estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and 
transportation. For public entities, ASU 2015-11 is effective for fiscal years beginning after December 15, 2016 and interim 
periods within those fiscal years. Early application is permitted as of the beginning of an interim or annual reporting period. 
We do not expect the adoption of this standard to have a material impact on our financial statements. 

In  September  2015,  the  FASB  issued  ASU  No.  2015-16,  Business  Combinations  (Topic  805)  –  Simplifying  the 
Accounting  for  Measurement-Period  Adjustments).  ASU  2015-16  requires  that  an  acquirer  recognize  adjustments  to 
provisional  amounts  that  are  identified  during  the  measurement  period  in  the  reporting  period  in  which  the  adjustment 
amounts are determined. Prior to the issuance of the standard, entities were required to retrospectively apply adjustments 
made to provisional amounts recognized in a business combination. For public entities, ASU 2015-16 is effective for fiscal 
years, and interim periods within those years, beginning after December 15, 2015, and early adoption is permitted. We do 
not expect the adoption of this standard to have a material impact on our financial statements. 

In November 2015, the FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of 
Deferred  Taxes.  ASU  2015-17  requires  that  deferred  tax  liabilities  and  assets  be  classified  as  noncurrent  in  a  classified 
statement of financial position. The current requirement that deferred tax liabilities and assets of a tax-paying component of 
an entity be offset and presented as a single amount is not affected by the amendments in ASU 2015-17. For public entities, 
ASU 2015-17 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. Early 
adoption is permitted and the standard may be applied either retrospectively or on a prospective basis to all deferred tax assets 
and liabilities presented. We will adopt this standard effective January 1, 2017 and do not expect the adoption of this standard 
to have a material impact on our financial statements. 

In January 2016, the FASB issued ASU No. 2016-01 Financial Instruments - Overall (Subtopic 825-10): Recognition 
and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01 modifies certain aspects of the recognition, 
measurement, presentation, and disclosure of financial instruments. For public entities, ASU 2016-01 is effective for fiscal 
years, and interim periods within those years, beginning after December 15, 2017, and early adoption is permitted. We do 
not expect the adoption of this standard to have a material impact on our financial statements. 

In February 2016, the FASB issued ASU No. 2016-02 Leases (Topic 842). ASU 2016-02 impacts any entity that enters 
into  a  lease  with  some  specified  scope  exceptions.  The  guidance  updates  and  supersedes  Topic  840,  Leases.  For  public 
entities, ASU 2016-02 is effective for fiscal years, and interim periods with those years, beginning after December 15, 2018, 
and early adoption is permitted. We have not evaluated the impact of this guidance, but do not expect the adoption of this 
standard to have a material impact on our financial statements. 

Note 3 — Loss Per Share 

Net losses are divided by the weighted average number of common shares outstanding during the year to calculate basic 
net loss per common share. Diluted net loss per common share is calculated to provide the impact of stock options and other 
stock-based awards. The following table sets forth the computation of basic and diluted loss per share (in thousands, except 
per share data):

Unbilled Receivables 

We currently have unbilled receivables pertaining to customer contractual holdback provisions, whereby we will invoice 
the final retention payment(s) due under certain sales contracts in the next 2 to 31 months. The customer holdbacks represent 
amounts intended to provide a form of security for the customer; accordingly, these receivables have not been discounted to 
present value.

Depreciation  and  amortization  expense  related  to  all  property  and  equipment  was  approximately  $3.2  million,  $3.2 

million, and $2.9 million for the years ended December 31, 2015, 2014, and 2013, respectively. 

Unamortized  computer  software  cost  was  $1.0  million  and  $1.3  million  at  year  end  December  31,  2015  and  2014, 
respectively. Depreciation expense related to computer software was $0.4 million, $0.4 million, and $0.2 million for the years 
ended December 31, 2015, 2014, and 2013, respectively. The increase in depreciation expense in 2014 related to computer 
software related to the implementation of a new enterprise resource planning (“ERP”) system in 2013. 

Construction in progress costs at December 31, 2015 primarily relate to leasehold improvements. As of December 31, 
2015, there were no additional costs to complete the project, however, the project had not been placed in service and therefore 
was not subject to depreciation or amortization. The project was implemented in the first quarter of 2016.

The Company monitors investments for other-than-temporary impairment. It was determined that unrealized gains and

resulted from fluctuating interest rates, rather than a deterioration of the credit worthiness of the issuers. The Company is 
unlikely to experience gains or losses if these securities are held to maturity. In the event that the Company disposes of these 
securities before maturity, it is expected that the realized gains or losses, if any, will be immaterial.  

Expected maturities can differ from contractual maturities because borrowers may have the right to prepay obligations 
without prepayment penalties. The amortized cost and fair value of available-for-sale securities that had stated maturities as 
of December 31, 2015 are shown below by contractual maturity (in thousands):

Note 6 — Goodwill and Intangible Assets 

Goodwill 

Goodwill as of December 31, 2015 was the result of our acquisition of Pump Engineering, LLC in December 2009. 
During the third quarter of 2015, we changed the measurement date of our annual goodwill impairment test from the fourth 
quarter to July 1. This change was not material to our Consolidated Financial Statements as it did not result in the delay, 
acceleration, or avoidance of an impairment charge. We believe this timing better aligns the goodwill impairment test with 
our strategic business planning process, which is a key component of the goodwill impairment test. The impairment test 
performed as of July 1, 2015 determined that goodwill was not impaired. No impairment of goodwill has been recorded in 
the accompanying Consolidated Financial Statements. 

The net carrying amount of goodwill was $12.8 million for the years ended December 31, 2015 and 2014.

Note 7 — Fair Value Measurements 

We follow the authoritative guidance for fair value measurements and disclosures that, among other things, defines fair 
value, establishes a consistent framework for measuring fair value, and expands disclosure for each major asset and liability 
category measured at fair value on either a recurring or nonrecurring basis. Fair value is defined as an exit price that would 
be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair 
value is a market-based measurement that should be determined based on assumptions that market participants would use in 
pricing an asset or liability. 

The framework for measuring fair value provides a hierarchy that prioritizes the inputs to valuation techniques used in 

measuring fair value as follows: 

Level1—  Quoted prices (unadjusted) in active markets for identical assets or liabilities; 
Level2—  Inputs other than quoted prices included within Level 1 that are either directly or indirectly observable; and 
Level3—  Unobservable inputs in which little or no market activity exists, therefore requiring an entity to develop its
own estimates of assumptions that market participants would use in pricing an asset or liability. 

Fair Value of Financial Instruments 

The  carrying  values  of  cash  and  cash  equivalents,  restricted  cash,  accounts  receivable,  accounts  payable,  and  other 
accrued expenses approximate fair value due to the short-term maturity of those instruments. For our investments in available-
for-sale securities, if quoted prices in active markets for identical investments are not available to determine fair value (Level 
1), then we use quoted prices for similar assets or inputs other than the quoted prices that are observable either directly or 
indirectly (Level 2).  

The investments included in Level 2 consist primarily of municipal, corporate, and agency obligations. The asset also 
included in Level 2 consists of the premium paid for foreign currency put options. The fair value of this asset was determined 
based on the time value of the options as it was determined there was no intrinsic value of the options. 

The fair value of financial assets and liabilities measured on a recurring basis is as follows (in thousands):

Lines of Credit 

In June 2012, we entered into a loan agreement (the “2012 Agreement”) with a financial institution. The 2012 Agreement 
matured in and was amended in June 2015. The 2012 Agreement, as amended, provides for a total available credit line of 
$16.0 million. Under the 2012 Agreement, we are allowed to draw advances not to exceed, at any time, $10.0 million as 
revolving loans. The total stand-by letters of credit issued under the 2012 Agreement may not exceed the lesser of the $16.0 
million credit line or the credit line minus all outstanding revolving loans. At no time may the aggregate of the revolving 
loans and stand-by letters of credit exceed the total available credit line of $16.0 million. Revolving loans may be in the form 
of a base rate loan that bears interest equal to the prime rate plus 0% or a Eurodollar loan that bears interest equal to the 
adjusted LIBOR rate plus 1.25%. Stand-by letters of credit are subject to customary fees and expenses for issuance or renewal. 
The unused portion of the credit facility is subject to a facility fee in an amount equal to 0.25% per annum of the average 
unused portion of the revolving line. The 2012 Agreement, as amended, also requires us to maintain a cash collateral balance 
equal to 101% of all outstanding advances and all outstanding stand-by letters of credit collateralized by the line of credit. 
The 2012 Agreement, as amended, matures in June 2018 and is collateralized by substantially all of our assets. 

As of December 31, 2015 and 2014, there were no advances drawn under the 2012 Agreement, as amended. Stand-by 
letters of credit collateralized under the 2012 Agreement, as amended, totaled $3.8 million and $3.1 million as of December

31,  2015  and  2014,  respectively.  Total  cash  restricted  related  to  these  stand-by  letters  of  credit  totaled  $3.8  million  and 
$3.1million as of December 31, 2015 and 2014, respectively. 

We are subject to certain financial and administrative covenants under the 2012 Agreement, as amended. As of December 

31, 2015, we were in compliance with these covenants. 

In 2009, we entered into a loan and security agreement (the “2009 Agreement”) with another financial institution. The 
2009 Agreement, as amended, provided a total available credit line of $16.0 million. Under the 2009 Agreement, we were 
allowed to draw advances of up $10.0 million on a revolving line of credit or utilize up to $15.9 million as collateral for 
stand-by  letters  of  credit, provided  that  the aggregate  of  the outstanding  advances  and  collateral  did not  exceed  the  total 
available credit line of $16.0 million. Advances under the revolving line of credit incurred interest based on a prime rate 
index or LIBOR plus 1.375%. The 2009 Agreement, as amended, required us to maintain cash collateral balances equal to at 
least 101% of the face amount of all outstanding stand-by letters of credit collateralized by the line of credit and 100% of the 
amount of all outstanding advances. The 2009 Agreement, as amended, expired in May 2012, at which time we became 
required to maintain a cash collateral balance equal to at least 105% of the face amount of all outstanding stand-by letters of 
credit collateralized by the line of credit.  

There were no advances drawn under the 2009 Agreement’s credit line at the time of expiration. Remaining stand-by 
letters of credit issued under the 2009 Agreement, for which we had restricted cash, totaled zero and $2.3 million, as of 
December 31, 2015 and 2014, respectively. Total cash restricted related to these stand-by letters of credit totaled zero and 
$2.4 million as of December 31, 2015 and 2014, respectively. 

See Note 9 — “Commitments and Contingencies,” for further discussion of restricted cash associated with stand-by 

letters of credit.

During the year ended December 31, 2013, the Company adjusted previously established warranty reserves. The accruals 
had been made based on historic warranty claim rates during 2010 and 2011, a period that covered the integration of the PEI 
acquisition  and  related  manufacturing  operations  into  the  Company’s  existing  operation.  At  December  31,  2013,  the 
Company revised the rates based on warranty claim data during the two-year period after integration, which covered 2012 
and 2013. This resulted in a release of accruals related to expired warranties, which increased gross profit and reduced net 
loss by $0.3 million. 

Purchase Obligations 

We have purchase order arrangements with our vendors for which we have not received the related goods or services as 
of December 31, 2015. These arrangements are subject to change based on our sales demand forecasts, and we have the right 
to cancel the arrangements prior to the date of delivery. The majority of these purchase order arrangements were related to 
various  raw  materials  and  components  parts.  As  of  December  31,  2015,  we  had  approximately  $1.5  million  of  open 
cancellable purchase order arrangements related primarily to materials and parts. 

Guarantees 

We enter into indemnification provisions under our agreements with other companies in the ordinary course of business, 
typically with customers. Under these provisions, we generally indemnify and hold harmless the indemnified party for losses 
suffered or incurred by the indemnified party as a result of our activities, generally limited to personal injury and property 
damage caused by our employees at a customer’s desalination plant in proportion to the employee’s percentage of fault for 
the accident. Damages incurred for these indemnifications would be covered by our general liability insurance to the extent 
provided by the policy limitations. We have not incurred material costs to defend lawsuits or settle claims related to these 
indemnification agreements. As a result, the estimated fair value of these agreements is not material. Accordingly, we had no 
liabilities recorded for these agreements as of December 31, 2015 and 2014. 

In certain cases, we issue warranty and product performance guarantees to our customers for amounts ranging from 5% 
to 15% of the total sales agreement to endorse the execution of product delivery and the warranty of design work, fabrication, 
and operating performance of our devices. These guarantees are generally stand-by letters of credit that typically remain in 
place for periods ranging up to 24 months, and in some cases, up to 68 months. The stand-by letters of credit, collateralized 
by restricted cash, are as follows (in thousands):

Cash collateral balances under the 2009 Agreement required a premium equal to approximately 5.0% of the amount of 
the corresponding stand-by letters of credit. Cash collateral balances under the 2012 Agreement require a premium equal to 
approximately 1.0% of the amount of the corresponding stand-by letters of credit. As a result, the balance of restricted cash 
related to stand-by letters of credit at December 31, 2015 and 2014 totaled $3.8 million and $5.5 million, respectively.  

Litigation 

On September 10, 2014, the Company terminated the employment of its Senior Vice President, Sales, Borja Blanco, on 
the basis of breach of duty of trust and conduct leading to conflict of interest. On October 3, 2014, Mr. Blanco filed a labor 
claim against ERI Iberia in Madrid, Spain alleging breach of contract and termination without cause. The claim seeks wages 
(salary and bonus) of €567,000 and alleged stock option gains of €630,000. On November 13, 2015, a hearing was held 
before the labor court in Madrid, Spain. On December 2, 2015, the labor court ruled that it did not have jurisdiction over Mr. 
Blanco’s claims. Mr. Blanco has appealed the ruling. At this time, the Company has not determined that an award to Mr. 
Blanco is probable. 

In January 2015, two stockholder class action complaints were filed against the Company in the Northern District of 
California, on behalf of Energy Recovery stockholders under the captions, Joseph Sabatino v. Energy Recovery, Inc. et al. 
and Thomas C. Mowdy v. Energy Recovery, Inc. et al. The complaints have now been consolidated under the caption In Re 
Energy Recovery Inc. Securities Litigation. The complaint alleges violations of Section 10(b), Rule 10b-5, and Section 20(a) 
of the Securities Exchange Act of 1934 and seeks the recovery of unspecified monetary damages. We are not able to estimate 
the possible loss, if any, due to the early state of this matter.

caption, Barnes v. Energy Recovery, Inc. et al. case no. 4:16-cv-00477 EMC, alleging numerous legal claims including, but 
not limited to, wrongful termination and negligent and/or intentional misrepresentations to induce Mr. Barnes to join the 
Company. At this time, the Company is not able to estimate a possible loss, if any, due to the early state of this matter.

We had gross deferred tax assets of approximately $23.2 million and $22.0 million at December 31, 2015 and 2014, 
respectively, relating principally to accrued expenses and tax effects of net operating loss carry-forwards. In assessing the 
recoverability  of  deferred  tax  assets,  we  consider  whether  it  is  more  likely  than  not  that  the  assets  will  be  realized.  The 
ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in 
which those temporary differences become deductible. 

We assess the available positive and negative evidence to estimate if sufficient future taxable income will be generated 
to  use  the  existing  deferred  tax  assets.  In  making  such  a  determination,  we  consider  all  available  positive  and  negative 
evidence, including recent results of operations, scheduled reversals of deferred tax liabilities, projected future income, and 
available tax planning strategies. A significant piece of the negative evidence evaluated was the cumulative loss incurred 
over the three-year period ended December 31, 2015. Such objective evidence limits the ability to consider other subjective 
evidence, such as our projection for future growth. 

On the basis of this evaluation, as of December 31, 2015, a valuation allowance of approximately $21.4 million has been 
recorded to reduce our deferred income tax assets to the amount that is more likely than not to be realized, an increase of 
$1.08 million from December 31, 2014. The valuation allowance represents a provision for uncertainty as to the realization 
of tax benefits from these deferred income tax assets. We will continue to evaluate the tax benefit uncertainty and will adjust, 
if warranted, the valuation allowance in future periods to the extent that our deferred income tax assets become more likely 
than not to be realizable. 

At December 31, 2015 and 2014, we had net operating loss carry-forwards of approximately $41.0 million and $38.8 
million, respectively, for federal and $14.9 million and $14.8 million, respectively, for California. As of December 31, 2015, 
the federal and California net operating loss carryovers include $1.3 million and $217,000 of excess stock based compensation 
deductions that will result in an increase in Additional Paid in Capital when recognized. The net operating loss carry-forwards, 
if not utilized, will begin to expire in 2018 for federal and 2029 for California purposes. Utilization of the net operating loss 
carry-forwards is subject to a substantial annual limitation due to the ownership change limitations provided by the Internal 
Revenue Code and similar state provisions. The annual limitation will result in the expiration of the net operating loss carry-
forwards before utilization. We have estimated the amount which may ultimately be realized and recorded deferred tax assets 
accordingly. In addition, at December 31, 2015 and 2014, we had net operating loss carry-forwards of approximately $4.4 
million and $0, respectively, for Ireland tax purposes. Ireland net operating losses carryover indefinitely.

At December 31, 2015 and 2014, we had credit carry-forwards of approximately $1.2 million and $980,000, respectively, 
for  federal  and  approximately  $1.1  million  and  $836,000,  respectively,  for  California.  The  credit  carry-forwards,  if  not 
utilized, will begin to expire in 2030 for federal purposes. The California credit carry-forwards do not expire. Utilization of 
the credit carry-forwards may be subject to a substantial annual limitation due to the ownership change limitations provided 
by the Internal Revenue Code and similar state provisions. 

Measurement of uncertain tax positions is based on judgment regarding the largest amount that is greater than 50% likely 
of being realized upon the ultimate settlement with a taxing authority. As of December 31, 2015 and 2014, we had $394,000 
and $292,000, respectively, of unrecognized tax benefits, none of which, if recognized, would affect our effective tax rate. 
The aggregate changes in the balance of the gross unrecognized tax benefit were as follows (in thousands):

We recognize interest and/or penalties related to uncertain tax positions in income tax expense. There were no accrued 

interest or penalties associated with any unrecognized tax benefits as of December 31, 2015 and 2014. 

We are subject to taxation in the U.S. and various states and foreign jurisdictions. There are no ongoing examinations 
by taxing authorities at this time. We believe that, as of December 31, 2015, the gross unrecognized tax benefits will not 
materially change in the next twelve (12) months, that we have adequately provided for any reasonably foreseeable outcome 
related to any tax audit, and that any settlement will not have a material adverse effect on the consolidated financial position 
or results of operation; however, there can be no assurances as to the possible outcomes. 

Note 11 — Stockholders’ Equity 

Preferred Stock 

We have the authority to issue 10,000,000 shares of $0.001 par value preferred stock. Our Board of Directors has the 
authority, without action by our stockholders, to designate and issue shares of preferred stock in one or more series. The 
Board of Directors is also authorized to designate the rights, preferences, and voting powers of each series of preferred stock, 
any or all of which may be greater than the rights of the common stock including restrictions of dividends on the common 
stock, dilution of the voting power of the common stock, reduction of the liquidation rights of the common stock, and delaying 
or preventing a change in control of the Company without further action by our stockholders. To date, the Board of Directors 
has not designated any rights, preferences, or powers of any preferred stock, and as of December 31, 2015 and 2014, no 
shares of preferred stock were issued or outstanding. 

Common Stock 

We have the authority to issue 200,000,000 shares of $0.001 par value common stock. Subject to the preferred rights of 
the holders of shares of any class or series of preferred stock as provided by our Board of Directors with respect to any such 
class or series of preferred stock, the holders of the common stock shall be entitled to receive dividends, as and when declared 
by the Board of Directors. In the event of any liquidation, dissolution, or winding up of the Company, whether voluntary or 
involuntary, after the distribution or payment to the holders of shares of any class or series of preferred stock as provided by 
the  Board  of  Directors  with  respect  to  any  such  class  or  series  of  preferred  stock,  the  remaining  assets  of  the  Company 
available  for  distribution  to  stockholders  shall  be  distributed  among  and  paid  to  the  holders  of  common  stock  ratably  in 
proportion to the number of shares of common stock held by them. At December 31, 2015, 54,948,235 shares were issued 
and 52,468,779 shares were outstanding. At December 31, 2014, 54,398,421 shares were issued and 51,918,965 shares were 
outstanding  

Stock Repurchase Program 

In January 2016, the Board of Directors authorized a stock repurchase program under which shares, not to exceed $6.0 
million in aggregate cost, of our outstanding common stock can be repurchased through June 30, 2016 at the discretion of 
management.  We  account  for  stock  repurchases  using  the  cost  method.  Cost  includes  fees  charged  in  connection  with

acquiring  the  treasury  stock.  As  of  February  29,  2016,  673,700  shares  at  an  aggregate  cost  of  $4.1  million  had  been 
repurchased under this authorization. 

A  stock  repurchase  program  was  not  in  place  during  the  year  ended  December  31,  2015,  therefore  no  shares  were 

repurchased during 2015. 

In February 2014, our Board of Directors authorized a stock repurchase program under which up to three million shares, 
not to exceed $6.0 million in aggregate cost, of our outstanding common stock could be repurchased through December 31, 
2014 at the discretion of management. During the year ended December 31, 2014, 696,853 shares at an aggregate cost of 
$2.8 million were repurchased under this authorization. This 2014 repurchase authorization expired on December 31, 2014. 

Warrants 

There were no warrants outstanding as of December 31, 2015. 

During the year ended December 31, 2015, warrants to purchase 200,000 shares of common stock were exercised for 

cash at a price of $1.00 per share. The proceeds received for this exercise totaled $200,000. 

During  the  year  ended  December  31,  2014,  warrants  to  purchase  450,000  shares  of  common  stock  were  exercised.

Note 12 — Stock-Based Compensation 

Stock Option Plan 

We maintain an equity incentive plan, the Amended and Restated 2008 Equity Incentive Plan (the “Plan”), that permits 
the grant of stock options, stock appreciation rights (“SARs”), restricted stock (“RS, RSAs, or RSUs”), performance units, 
performance shares, and other stock-based awards to employees, officers, directors, and consultants. We have granted stock 
options SARs, RSUs, and RSAs under this plan. Stock-based awards granted under this plan generally vest over four years 
and expire no more than ten years after the date of grant. Under the Plan, our Board of Directors is authorized to reserve for 
issuance  up  to  10,000,000  shares  of  common  stock,  all  of  which  had  been  reserved  as  of  December  31,  2015.  The  Plan 
supersedes  all  previously  issued  stock  option  plans  and  is  currently  the  only  available  plan  from  which  options  may  be 
granted.  Shares  available  for  grant  under  the  Plan  were  1,536,009  and  2,808,973  at  December  31,  2015  and  2014, 
respectively.

Restricted Stock 

There were no outstanding restricted stock awards as of December 31, 2015. 

On December 31, 2014, the Company granted 27,609 shares of restricted stock to a member of its Board of Directors as 
compensation for services provided in addition to his normal director services. The restricted shares were fully vested on 
March 16, 2015.  

In July 2009, we issued 60,000 restricted stock units to key management team members under the Plan. The restricted 
stock units vested 25% on the first anniversary of the grant date and 1/48th monthly thereafter dependent upon continued 
employment. As the restricted stock units vested, the units were settled in shares of common stock based on a one-to-one

Stock Based Compensation 

We applied ASC 718, “Compensation — Stock Compensation,” during the years ended December 31, 2015, 2014, and 
2013 and recognized related compensation expense of $4.1 million, $2.1 million, and $2.2 million, respectively, related to 
stock options and restricted stock units. 

The fair value of restricted stock units granted to employees is based on our common stock price on the date of grant. 
The fair value of stock options granted to employees is based on the Black-Scholes option pricing model. To determine the 
inputs  for  the  Black-Scholes  option  pricing  model,  we  are  required  to  develop  several  assumptions,  which  are  highly 
subjective. We determine these assumptions as follows: 

Expected Term: For the year ended 2013, we blended the Company’s historical data with disclosure information from 
similar  publicly-traded  companies  to  develop  reasonable  expectations  about  future  exercise  patterns  and  post-vesting 
employment termination behavior to determine the expected term of options. For the years ended December 31, 2015 and 
2014, we used only our own historical data to determine the expected term of options based on historical exercise data. As 
there was no historical exercise data for non-employee directors, the Company determined the expected term based on the 
simplified method. 

Expected Volatility: For the year ended 2013, the expected volatility was determined using a blend of the historical 
volatility of our stock since becoming a public entity in 2008 and the volatility of a representative industry peer group. For 
the years ended December 31, 2015 and 2014, we determined expected volatility based on our own historical data and the 
corresponding expected term that was determined using the Company’s historical exercise data. 

Risk-Free Interest Rate: The risk-free rate is based on U.S. Treasury issues with remaining terms similar to the expected 

term on the options. 

Dividend  Yield:  We  have  never  declared  or  paid  any  cash  dividends  and  do  not  plan  to  pay  cash  dividends  in  the 

foreseeable future; therefore, we use an expected dividend yield of zero in the valuation model. 

Forfeitures: We estimate forfeitures at the time of grant and revise those estimates periodically in subsequent periods if 
actual forfeitures differ from those estimates. We use historical data to estimate pre-vesting option forfeitures and record 
stock-based  compensation  expense  only  for  those  awards  that  are  expected  to  vest.  All  stock-based  payment  awards  are 
amortized on a straight-line basis over the requisite service periods of the awards, which are generally the vesting periods. If 
our actual forfeiture rate is materially different from its estimate, the stock-based compensation expense could be significantly 
different from what we have recorded in the current period.

Stock-Based Compensation — Non-Employee Stock Options 

We account for awards granted to non-employees, other than members of our Board of Directors, in accordance with 
ASC 505-50, “Equity-Based Payments to Non-Employees,” which requires such awards to be recorded at their fair value on 
the  measurement  date  using  the  Black-Scholes  option  pricing  model.  The  measurement  of  stock-based  compensation  is 
subject to periodic adjustment as the underlying awards vest. 

The fair value of stock options issued to non-employees other than members of our Board of Directors was calculated 
using the Black-Scholes option pricing model based on the following assumptions. There were no stock options issued to or 
outstanding for non-employees other than members of our Board of Directors during 2015 and 2014:

Note 13 — Business Segment and Geographic Information 

We manufacture and sell high-efficiency energy recovery devices and pumps as well as related products and services. 

Our chief operating decision-maker (“CODM”) is the chief executive officer (“CEO”).  

Following the appointment of a new CEO in April 2015, new internal reporting was developed for making operating 
decisions and assessing financial performance. Beginning July 1, 2015, a new internal organizational and reporting structure 
was implemented and we began reporting segment information on a basis reflecting this new structure. Prior period amounts 
have been adjusted retrospectively to reflect this new internal reporting structure.

Our reportable operating segments consist of the Water Segment and the Oil & Gas Segment. These segments are based 
on the industries in which the products are sold, the type of energy recovery device sold, and the related products and services. 
The Water Segment consists of revenue associated with products sold for use in reverse osmosis water desalination, as well 
as the related identifiable expenses. The Oil & Gas Segment consists of revenue associated with products sold for use in gas 
processing, chemical processing, and hydraulic fracturing, as well as related identifiable expenses. Operating income for each 
segment excludes other income and expenses and certain expenses managed outside the operating segment. Costs excluded 
from operating income include various corporate expenses such as certain share-based compensation expenses, income taxes, 
and other separately managed general and administrative expenses not related to the identified segments. Assets and liabilities 
are reviewed at the consolidated level by the CODM and are not accounted for by segment. The CODM allocates resources 
to and assesses the performance of each operating segment using information about its revenue and operating income (loss).

Note 14 — Concentrations 

Concentration of Credit Risk 

We  have  an  investment  portfolio  of  fixed  -income  marketable  debt  securities,  including  amounts  classified  as  cash 
equivalents,  short-term  investments,  and  long-term  investments.  The  primary  objective  of  our  investment  activities  is  to 
preserve principal and liquidity while at the same time maximizing yields without significantly increasing risk. We invest 
primarily in investment-grade short-term and long-term debt instruments of corporate issuers and the U.S. government and 
its agencies. These investments are subject to counterparty credit risk. To minimize this risk, we invest pursuant to a Board-
approved investment policy. The policy mandates high credit rating requirements and restricts our exposure to any single 
corporate issuer by imposing concentration limits.  

Our accounts receivable are derived from sales to customers in the water desalination industry located around the world. 
We generally do not require collateral to support customer receivables, but frequently require export letters of credit securing 
payment. We perform ongoing evaluations of our customers’ financial condition and periodically review credit risk associated 
with  receivables.  An  allowance  for  doubtful  accounts  is  determined  with  respect  to  receivable  amounts  that  we  have 
determined to be doubtful of collection using specific identification of doubtful accounts and an aging of receivables analysis 
based on invoice due dates. Actual collection losses may differ from our estimates, and such differences could be material to 
the financial position, results of operations, and cash flows. Uncollectible receivables are written off against the allowance 
for doubtful accounts when all efforts to collect them have been exhausted, while recoveries are recognized when they are 
received. 

Customer Concentration  

Customers accounting for 10% or more of our combined accounts receivable and unbilled receivables were as follows: 

Customer A .............................................................................................................     
Customer B .............................................................................................................

Note 15 — Restructuring Activities  

Consolidation of North American Operations 

In 2011, we completed a restructuring plan to consolidate our North American production activities and transfer our 
Michigan-based operations to our manufacturing center and headquarters in San Leandro, California. The consolidation was 
expected  to  reduce  costs,  improve  efficiencies,  and  enhance  research  and  development  activities.  For  the  year  ended

December  31,  2011,  we  recorded  total  pre-tax  charges  of  $3.1  million  related  to  this  plan.  The  consolidation  of  these 
operations was substantially completed as of December 31, 2011. 

In 2012, we recorded additional restructuring charges related to this plan of $369,000. With the exception of potential 
further impairment adjustments for assets held for sale, we did not anticipate further costs related to this restructuring activity. 

In 2013, we impaired the building and land held for sale by $44,000 to reduce the carrying value to estimated fair value. 
The building and land were sold in September 2013. Net proceeds from the sale totaled $1.2 million, resulting in a loss on 
sale  of  $0.1  million.  As  the  assets  were  part  of  the  restructuring  plan,  the  loss  on  sale  was  reported  in  the  Consolidated 
Statement of Operations in the caption “Restructuring Charges.”  

During the years ended December 31, 2015 and 2014, there were no further costs related to this restructuring activity. 

The major components of the restructuring charges relating to the consolidation of our North American operations were 

as follows (in thousands):

Note 16 — Schlumberger License Agreement 

On October 14, 2015, the Company and Schlumberger Technology Corporation (“Schlumberger”) signed a fifteen (15) 
year license agreement which provides Schlumberger with exclusive worldwide rights to the Company’s VorTeq hydraulic 
fracturing technology for use in hydraulic fracturing onshore applications (the “Schlumberger License Agreement”).  

The  VorTeq  is  made  up  of  cartridges  though  which  hydraulic  fracturing  fluid  passes  and  a  missile  that  houses  the 
cartridges. The Schlumberger License Agreement includes up to $125 million in consideration paid in stages: (i) a $75 million 
non-refundable  upfront  payment;  and  (ii)  two  (2)  payments  of  $25  million  each  upon  achieving  specified  development 
milestones (“Milestone Payment 1 and 2”). Once the VorTeq is commercialized, Schlumberger will begin paying ongoing 
recurring monthly fees to the Company for supply and service of the cartridges based on the number of VorTeq’s in operation 
which is subject to the greater of a minimum adoption curve or the adoption rate of the technology. 

The  agreement  includes  both  contingent  and  non-contingent  deliverables.  Non-contingent  deliverables  include  the 
license, development services to commercialize the technology, and support services. Contingent deliverables include the 
supply and service of the cartridges and development services related to the integration of the commercialized technology 
with Schlumberger equipment. 

The  Company  applied  the  guidance for  multi-element  arrangements  in identifying deliverables, determining  units of 
accounting, allocating total contract consideration to the units of accounting, and recognizing revenue. It was determined that 
the  non-contingent  deliverables  did  not  have  stand-alone  value  individually,  but  did  on  a  combined  basis,  and  therefore 
represented a unit of accounting. The license will provide access to the technology over the term of the agreement and, along 
with the support, is the final deliverable in this unit of accounting. The $75 million upfront payment was allocated to this unit 
of accounting and revenue is recognized on a straight-line basis over the fifteen (15) year term of the license, starting from 
the day that the license agreement was signed and all services commenced. We recognized license fees of $1.0 million in 
2015 as License and development revenue and we had a deferred revenue balance of $74.0 million related to the upfront 
license fee as of December 31, 2015. The cartridge supply and support services are not assessed to have stand-alone value 
independent of each other and fees for these deliverables will be recognized as earned. 

Milestone Payment 1 of $25 million is payable upon a successful five (5) stage yard test at a Schlumberger test facility. 
If  a  successful  yard  test  is  not  achieved  by  the  target  date,  the  payment  will  be  delayed  until  the  successful  yard  test  is 
achieved. The Milestone Payment 2 of $25 million is payable upon a successful twenty (20) stage hydraulic fracturing at a 
Schlumberger customer live well. If success is not achieved by the target date, the payment will be delayed until the successful 
live well test is achieved. The achievement of either milestone and receipt of the related payments is subject to a high degree 
of uncertainty.

With respect to the Milestone Payments, the Company determined the payments did meet the definition of a substantive 
milestone.  The  factors  considered  in  the  determination  that  each  milestone  was  substantive  included  whether  the 
consideration  earned  from  the  achievement  of  the  milestone  is  commensurate  with  the  vendor's  performance  or  the 
enhancement  of  value;  the  degree  of  certainty  in  achieving  the  milestone;  whether  the  milestone  relates  solely  to  past 
performance; and whether the consideration earned from the achievement of the milestone is reasonable relative to all of the 
deliverables and payment terms within the arrangement. 

Since these milestone payments represent research and development deliverables in which performance obligations are 
satisfied over a period of time and in which the consideration is contingent upon uncertain future events or circumstances, 
the Company elected the milestone method of accounting and revenue will be recognized in the period in which the milestones 
are achieved. For the year ending December 31, 2015, no revenue was recognized for the Milestones Payments, nor in any 
other periods presented.  

Achievement of Milestone Payment 2 is the gating item to the commercialization of the VorTeq. Following Milestone 
Payment  2,  Schlumberger  will  begin  integrating  the  technology  into  its  fleets.  When  the  technology  is  integrated  into 
Schlumberger’s  fleets,  the  Company  will  begin  providing  cartridges  and  servicing  those  cartridges  which  will  generate 
ongoing recurring  revenues. The  monthly  recurring royalty  fee  per VorTeq  in  use will  be  paid  based on  the greater of a 
minimum adoption curve or the adoption rate of the technology. Further, a provision is made for an advance royalty payment 
to which recurring royalty fees will be applied. 

The exclusive nature of the agreement terminates if Schlumberger does not meet the specified minimum adoption curves. 
In  the  event  the  Company  is  not  able  to  meet  the  specified  development  milestones  and  successfully  commercialize  the 
technology, the license continues on an exclusive nature for the full term. 

With respect to the cartridges and associated service, royalty revenue will be recognized as royalties are earned, that is, 
in the period in which the contingency regarding royalties are resolved and the amount of royalties are fixed and determinable 
based on the cartridges delivered.

Item 9A — Controls and Procedures 

Evaluation of Disclosure Controls and Procedures 

Our management has evaluated, with the participation of our Chief Executive Officer and Chief Financial Officer, the 
effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities 
Exchange Act of 1934, or “Exchange Act”) as of the end of the period covered by this Annual Report on Form 10-K. Based 
on  that  evaluation,  our  Chief  Executive  Officer  and  Chief  Financial  Officer  have  concluded  that,  as  of  such  date,  our 
disclosure controls and procedures were effective to ensure that information we are required to disclose in reports that we 
file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in 
Securities  and  Exchange  Commission  rules  and  forms  and  that  such  information  is  accumulated  and  communicated  to 
management as appropriate to allow for timely decisions regarding required disclosure. 

Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives, and 
our Chief Executive Officer and Chief Financial Officer have concluded that these controls and procedures are effective at 
the  “reasonable  assurance”  level.  Our  management,  including  the  Chief  Executive  Officer  and  Chief  Financial  Officer, 
believes  that  a  control  system,  no  matter  how  well  designed  and  operated,  cannot  provide  absolute  assurance  that  the 
objectives of the control system are met, and that no evaluation of controls can provide absolute assurance that all control 
issues and instances of fraud, if any, within a company have been detected. 

Management’s Annual Report on Internal Control Over Financial Reporting and Attestation Report of the Registered 
Accounting Firm 

Management  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over  the  Company’s  financial 
reporting. Management assessed the effectiveness of the Company’s internal control over financial reporting as of December 
31, 2015. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations 
of the Treadway Commission (COSO) in Internal Control — Integrated Framework (2013). Based on the assessment using 
those  criteria,  management  concluded  that,  as  of  December  31,  2015,  our  internal  control  over  financial  reporting  was 
effective. 

The  Company’s  independent  registered  public  accountants,  BDO  USA,  LLP,  audited  the  Consolidated  Financial 
Statements included in this Annual Report on Form 10-K and have issued an audit report on the Company’s internal control 
over financial reporting. The report on the audit of internal control over financial reporting appears below.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

The Board of Directors and Stockholders of 
Energy Recovery, Inc. 
San Leandro, California 

We have audited Energy Recovery, Inc.’s internal control over financial reporting as of December 31, 2015, based on 
criteria  established  in  Internal  Control  —  Integrated  Framework  (2013)  issued  by  the  Committee  of  Sponsoring 
Organizations of the Treadway Commission (the COSO criteria). Energy Recovery, Inc.’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, which is included in the accompanying “Item 9A, Management’s Annual Report on Internal Control 
Over Financial Reporting and Attestation Report of the Registered Public Accounting Firm”. Our responsibility is to express 
an opinion on the Company’s internal control over financial reporting based on our audit. 

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United 
States). 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, and testing and 
evaluating  the  design  and  operating  effectiveness  of  internal  control  based  on  the  assessed  risk.  Our  audit  also  included 
performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a 
reasonable basis for our opinion. 

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. 

In  our  opinion,  Energy  Recovery,  Inc.  maintained,  in  all  material  respects,  effective  internal  control  over  financial 

reporting as of December 31, 2015, based on the COSO criteria. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States),  the  Consolidated  Balance  Sheets  of  Energy  Recovery,  Inc.  as  of  December  31,  2015  and  2014,  and  the  related 
Consolidated Statements of Operations, Comprehensive Loss, Stockholders’ Equity, and Cash Flows for each of the three 
years in the period ended December 31, 2015, and our report dated March 3, 2016 expressed an unqualified opinion thereon.
