Fiscal Year 2019
Annual Report

ADVANCED DRAINAGE SYSTEMS, INC

Dear Fellow Shareholders,

Driven by excellent cooperation, disciplined planning and execution, we finished fiscal 2019 with strong 
financial performance, posting record net sales and Adjusted EBITDA for the year. Our fiscal 2019 revenue 
increased 4% to $1.4 billion, and our Adjusted EBITDA increased 10% to $232 million. We were able to 
achieve these results by providing best-in-class water management solutions to our customers, executing 
our conversion strategies to displace traditional materials and capturing the benefits of our operational and 
transportation initiatives. 

Revenue growth was driven by favorable pricing and volume growth in our domestic construction markets. 
We stayed focused on our key growth initiatives, including executing our market share model, driving 
growth in key geographies and selling our complete line of water management solutions. Our domestic 
construction market sales outpaced the broad-based growth in our end markets by 400 basis points and we 
experienced strong growth in key states, such as Texas, Florida, North Carolina, Georgia and Arizona. 

Internationally, we are seeing good growth in our Exports business and Canadian construction market sales. 
Mexico had a strong first half of the year, but the transition phase of the new government resulted in lower 
infrastructure investment and construction spending toward the end of the year.

From a profitability standpoint, successful execution of our growth strategies and efficiency initiatives as well 
as our commitment to continuous improvement resulted in 100 basis points of margin expansion this year. 
Our team did a great job managing through an inflationary cost environment this past year, and we are very 
pleased with our results. 

Our growth and profitability initiatives also led to an improvement in cash flow generation, which we 
used to return $75 million to our shareholders through a special dividend.  This special dividend payment 
demonstrates our commitment to returning capital to shareholders, as well as our confidence in the 
strength of our balance sheet. Importantly, we were able to return this cash to our shareholders without 
impacting our ability to execute on our organic growth and acquisition priorities. 

Our top priorities are investing in organic growth and strategic acquisitions. Our fiscal 2020 capital plans are 
focused on investing in growth and capacity to support high growth products in key regions, productivity 
and efficiency initiatives, and technological solutions for our support functions. In addition to these priorities, 
we have developed a robust acquisition process, widening the aperture of potential deals with more 
dedicated resources. We are looking at companies, product lines, and potential relationships based on their 
relatedness to our core markets, and the opportunity attractiveness of these targets. We believe this is the 
best way to create value for our shareholders. 

In addition to the priorities set forth above, over the last year we have taken steps to more effectively engage 
with our external communities. We released our first Sustainability Report in April 2019 to educate our 
stakeholders on our environmental and community impact. Sustainability is a core component of how we 
grow and operate our business as protecting water as a precious natural resource is at the very core of what we 
do. By providing innovative products, using industry leading recycling practices and being a good local citizen 
in the communities which we operate, we are growing our environmental, operational and social impact.

Finally, we are more actively engaging with the political community as we promote open material 
competition in public infrastructure projects. Studies show that open material competition reduces cost, 
fosters innovation and improves quality. The current process allows for a single material to be specified for 
storm water pipes on construction plans. By shifting this to defined system requirements and requiring 
bidding of all technically qualified materials, we can help stretch the value of every dollar spent on our 
publicly funded transportation systems.

Inaugural Investor Day and  
Three-Year Plan

In November 2018 we held our first Investor Day, presenting our 
three-year financial targets for the first time and detailing our plans 
to accelerating profitable growth through fiscal 2021. Our fiscal 2019 
results and fiscal 2020 targets are in line with the sales growth, 
margin expansion and cash flow generation targets we presented. 
Key initiatives to our plan are presented on the right.

Looking Forward to Fiscal 2020

As we move forward into the next fiscal year, we are focused on 
execution. We are excited about where we are headed and the 
opportunities in front of us.  We are beginning to get a taste of 
early returns from our continuous improvement initiatives in our 
supply chain, capital and leadership investments. We are also 
working to create a safety culture that changes mindsets, changes 
behaviors and encourages our employees to demonstrate safe 
habits in everything they do.  

I want to take this opportunity to thank two members of our 
Board of Directors, Richard Rosenthal and Abigail Wexner, who 
have chosen not to stand for re-election as directors at our 2019 
Annual Meeting. During Mr. Rosenthal’s tenure as a board member, 
he helped guide the company from a small, local start-up to 
the industry standard and leader. Ms. Wexner helped guide the 
company through our IPO, led our Nominating and Corporate 
Governance committee since then and was instrumental in the 
process of hiring a new leader after the retirement of our long-time 
CEO, Joe Chlapaty. We sincerely thank both Mr. Rosenthal and Ms. 
Wexner for all they have done to make Advanced Drainage Systems 
a success story. I also want to thank the talented workforce that has 
made our Company into what it is today, our Board of Directors and 
our shareholders, for your continued support and confidence in our 
team.

Sincerely, 

Scott Barbour 

President and CEO

Management of a Precious Resource

Protecting Aquifers in Texas

We are proud to be able to work closely with communities around the world to provide innovative solutions to address 
their water management challenges and protect our precious resources. This is a role we take seriously, as we know 
with each shipment, we are helping to improve the environments and quality of life for people everywhere. 

Central Texas is home to the Edwards Aquifer, an underground layer of sponge-like permeable rock, which also 
serves as the main source of drinking water for nearly two million people in the region. As one of our nation’s largest 
aquifers, this resource is the primary water supply for agriculture and industry in the region, feeding rivers, lakes 
and springs in the area, in addition to sustaining the lives of plants and animals. Protecting the water quality in the 
region is of utmost importance because chemicals that enter the water can quickly cause contamination, especially 
if pollutants enter the surface area surrounding the aquifer.

Quality Units to filter and remove fine

A local developer in Georgetown, TX was looking for a way to detain and clean the storm water runoff at a 
grocery store development site near the San Gabriel River, which feeds the aquifer. His engineers had considered 
constructing a pond or using a sand filtration system with a large detention system underneath but were struggling 
with cost and constructability. His ultimate goal was to protect the aquifer as much as possible while also 
controlling the storm water runoff. Our engineers were able to work with the developer to provide the solution he 
was looking for, including conveyance, detention and water treatment for the system which ultimately discharges 
into the San Gabriel River. Ultimately, we were able to build a system that exceeded the strict local guidelines, 
which are sensitive to this area. System highlights are above.

Our StormTech® chambers  
manage the retention  
and detention of over 

1.7 billion 

gallons of storm water run-off at a given time, protecting 
bodies of water, wetlands and shorelines.

Our BarracudaTM water quality units treat 

180,000+ 

gallons of water per minute  
during storm events. 

Florida Highlights

Since gaining our 100-year design service life approval 
in Florida DOT in 2012 (HDPE) and 2014 (HP), Florida 
has been a key growth state at ADS. We have been 
heavily focused on promoting our N-12, HP and Allied 
products in key growth areas, and our efforts are 
paying off. Here are a few places benefitting from our 
products across the state.

University of Florida baseball fans may be aware that 
construction of a new state of the art stadium broke 
ground in early 2019. The new stadium will seat 10,000 
fans, with athlete amenities, an infield practice facility and 
the field sitting on approximately 14 acres of land. Our 
N-12 pipe, StormTech retention chambers and Nyloplast 
catch basins were specified to provide the storm water 
drainage needs underneath the field, around the stadium 
and under the parking lot. 

Due to the high water table and tight surface area, 
contractors in Jacksonville, FL chose ADS products 
to service the storm water at an urban-style 
apartment complex. Using an innovative design, 
contractors actually built a pipe system beneath 
a storm water retention area to lower the water 
table and reduce the risk of flooding. The project 
required a full suite of storm water products, and 
ultimately used over 13,000 feet of N-12 and HP 
pipe, a StormTech retention system, Nyloplast 
catch basins, InsertaTee lateral connections and 
geotextiles, all provided by ADS.

The Florida Department of Transportation 
(FDOT) approved construction on I-95 
in Broward County, FL to extend an 
existing express lane and convert another 
lane, creating two express lanes in each 
direction to alleviate congestion and slow 
moving traffic. Breaking ground in January 
2019, the project required nearly seven 
miles of drainage along the side of the 
highway, and our HP pipe was chosen 
because of its overall cost effectiveness 
and ease of installation. Our pipe products 
are being chosen for FDOT and local 
infrastructure projects across the state – 
in Fiscal 2019 we sold nearly 200 miles 
of pipe on Florida street and highway 
infrastructure projects.

Industry Leading Recycling Solutions 

Sustainability is at the core of who we are and what we do. We are proud of the important 
work we are doing to have a positive environmental, operational and social impact.

We are the 6th largest recycling company in North America based on our recycling operations. In Fiscal 2019, we 
purchased 250 million pounds of post consumer recycled plastic and 150 million pounds of post industrial plastic 
– saving over 230 million gallons of water and preventing over 530 million pounds of CO2 equivalent from being 
released into the atmosphere. Our industry-leading resin blending program converts this post consumer and post 
industrial recycled materials into pipe products that can support America’s infrastructure and water management 
needs.

In fiscal 2019, we consumed

30% 

of the recycled pigmented HDPE 

bottles in the United States.

The amount of recycled HDPE we consumed through this 
general process in fiscal 2019 reduced our CO2 emissions 
equivalent by over 530 million pounds, which amounts to 
taking over  

51,000  

cars off the road.

The average 
life span of 
a consumer 
HDPE bottle 
is less than 1 
year. 

<1  
year
LIFE SPAN

These bottles 
as well as other 
plastics and 
recyclable 
materials are 
picked up through 
curbside recycling 
programs and 
taken to recycling 
facilities.

At the recycling 
facilities, 
materials are 
sorted and 
packed into 
bales. The bales 
are then taken 
to an ADS Green 
Line Polymer 
facility. 

At our facilities 
we unpack the 
bales and sort the 
plastic material. 
We then shred the 
plastic into flake 
and wash it to 
produce a clean 
flake material.

Flake may be 
further pelletized 
and is then 
used in the 
manufacturing 
of our HDPE 
products.

Our products 
are installed 
in storm water 
systems that 
are designed 
to last over 100 
years.

Business 

COMPANY OVERVIEW 

PART I 

Unless the context otherwise indicates or requires, as used in this Annual Report on Form 10-K, the terms 

“we,” “our,” “us,” “ADS” and the “Company” refer to Advanced Drainage Systems, Inc. and its directly- and 
indirectly-owned subsidiaries as a combined entity, except where it is clear that the terms mean only Advanced 
Drainage Systems, Inc. exclusive of its subsidiaries.  

We are the leading manufacturer of high performance thermoplastic corrugated pipe, providing a 
comprehensive suite of water management products and superior drainage solutions for use in the underground 
construction and infrastructure marketplace. Our broad product line includes corrugated high-density polyethylene 
(or “HDPE”) pipe, polypropylene (or “PP”) pipe and related water management products. Our products are 
generally lighter, more durable, more cost effective and easier to install than comparable alternatives made with 
traditional materials. Following our entrance into the non-residential construction market with the introduction of N-
12 corrugated polyethylene pipe in the late 1980s, our pipe has been displacing traditional materials, such as 
reinforced concrete, corrugated steel and PVC, across an ever expanding range of end markets, including non-
residential, residential, agriculture and infrastructure applications. We have established a leading position in many of 
these end markets by leveraging our national sales and distribution platform, our overall product breadth and scale 
and our manufacturing excellence. In the United States, our national footprint combined with our strong local 
presence and broad product offering make us the leader in an otherwise highly fragmented sector comprised of many 
smaller competitors. We believe the ADS brand has long been associated with quality products and market-leading 
performance. Our trademarked green stripe, which is prominently displayed on many of our products, serves as clear 
identification of our commitment to the customers and markets we serve.  

We believe the markets we serve in the United States represent approximately $11 billion of annual revenue 

opportunity. In addition, we believe the increasing acceptance of thermoplastic pipe products in international 
markets represents an attractive growth opportunity. We believe our extensive national footprint in the United States 
creates a cost and service advantage versus our HDPE pipe producing competitors, the largest of which has only 9 
HDPE pipe manufacturing plants in the U.S. and Canada and, according to the December 24, 2018 ranking by Plastics 
News of Pipe, Profile & Tubing Extruders, recently had estimated sales of $140 million, or approximately ten times 
less than our net sales in fiscal 2019.

SEGMENT INFORMATION 

For a discussion of segment and geographic information, see “Note 21. Business Segment Information” to our 
audited consolidated financial statements included in “Item 8. Financial Statements and Supplementary Data” of this 
Form 10-K. 

OUR MANUFACTURING AND DISTRIBUTION PLATFORM 

We have a leading domestic and international manufacturing and distribution infrastructure, serving customers 
in all 50 U.S. states as well as approximately 80 other countries through 56 manufacturing plants and 32 distribution 
centers, including 8 manufacturing plants and 5 distribution centers owned or leased by our joint ventures. We 
manufacture our corrugated pipe products in 17 different diameters ranging from 2” to 60” using a continuous 
extrusion process, where molten polyethylene or polypropylene is pushed through a die into a moving series of 
corrugated U-shaped molds. Blown air and vacuum are used to form the corrugations of the pipe which is pulled 
through a corrugator and then cut to length. We utilize customized and proprietary production equipment, which we 
believe is faster and more cost efficient than other pipe making equipment generally available in the market. 

Domestically, we are capable of producing more than one billion pounds of pipe annually on a standard five-
day per week schedule. Additional capacity is in place to support seasonal production needs and expected growth. 
Our production equipment is built to accept transportable molds and die tooling over a certain range of sizes so each 
plant is not required to house the full range of tooling at any given time. This transportability provides us with the 
flexibility to optimize our capacity through centrally coordinated production planning, which helps to adapt to 
shifting sales demand patterns while reducing the capital needed for tooling. With our large manufacturing footprint 
in place, we can support rapid seasonal growth in demand, focusing on customer service while minimizing 
transportation costs. 

The standard fittings products (tees, wyes, elbows, etc.) that we produce and sell to connect our pipe on 

jobsites are blow molded or injection molded at three domestic plants. In addition, customized fabricated fittings 
(e.g., more complex dual wall pipe reducers, bends or structures) are produced in 20 of our North American plants. 

4 

 
 
 
Table of Contents 

Advanced Drainage Systems, Inc. 

In addition to the extrusion of pipe, and blow molding and injection molding of fittings, we also use a variety of 
other processes in our manufacturing facilities. These processes include thermoforming, compression molding, and 
custom plastic welding and fabrication. The wide variety of production processes and expertise allow us to provide 
cost-effective finished goods at competitive prices delivered in a timely fashion to our customers. 

Our manufacturing plants have no process-related by-products released into the atmosphere, waterways, or 

solid waste discharge. During pipe production start-ups and size changeovers, non-compliant scrap and any 
damaged finished goods pipe are recycled through a grinder for internal re-use. 

International Presence – We own manufacturing facilities in Canada to produce our products for sale in the 
Canadian markets. We serve international markets primarily in Mexico and South America through joint ventures 
with local partners. Our joint venture strategy has provided us with local and regional access to key markets such as 
Mexico, Brazil, Chile, Argentina, and Peru. Our international joint ventures produce pipe and related products to be 
sold in their respective regional markets. We also have wholly-owned subsidiaries that distribute our pipe and 
related products in Europe and the Middle East. Combining local partners’ customer relationships, brand recognition 
and local management talent, with our world-class manufacturing and process expertise, broad product portfolio and 
innovation creates a powerful platform and exciting opportunities for continued profitable international expansion. 

Quality Control - We have two internal quality control laboratory facilities equipped and staffed to evaluate 
and confirm incoming raw material and finished goods quality in addition to the quality testing that is done at our 
manufacturing facilities. We conduct annual safety, product and process quality audits at each of our facilities, using 
centralized internal resources in combination with external third-party services. In the quality area, various national 
agencies such as National Transportation Product Evaluation Program (“NTPEP”), International Association of 
Plumbing and Mechanical Officials (“IAPMO”), Bureau de normalisation du Québec (“BNQ”), Intertek for 
Canadian Standards Association (“CSA”), Entidad Mexicana de Acreditacion A.C. (“EMA”) and NSF International 
and numerous state Departments of Transportation (“DOT”) and municipal authorities conduct both scheduled and 
unscheduled inspections of our plants to verify product quality and compliance to applicable standards. 

Training - Core to our commitment and enablement of a safe and productive manufacturing environment are 
our operational and management training programs. Through our ADS Academy, we deliver targeted role-specific 
training to our operations team members through a blended curriculum of online and hands-on training experiences 
covering safety, quality, product knowledge and manufacturing process. Our learning management system, which 
hosts over 600 custom modules, serves as the foundation of our operational training programs and provides us with 
appropriate scale, efficiency, and governance to support our growth. We have a strong commitment to the training of 
our manufacturing supervisors and managers in technical, management, and leadership subjects through intense 
role-based assimilation plans, e-learning and classroom-based development experiences. 

Fleet - We also operate an in-house fleet of approximately 700 tractors. Our effective shipping radius is 

between approximately 300 to 350 miles from one of our manufacturing plants or distribution centers. The 
combination of a dedicated fleet and team of company drivers allows greater flexibility and responsiveness in 
meeting dynamic customer jobsite delivery expectations. We strive to achieve less than three-day lead-time on 
deliveries and have the added benefit of redeploying fleet and driver assets to respond to short-term regional spikes 
in sales activity. For deliveries that are outside an economic delivery radius of our truck fleet, common carrier 
deliveries are tendered using a customized software platform to ensure that lowest delivered freight costs are 
achieved. In addition, in the United States and Canada, approximately 11% of our pipe volume is sold on a pick-up 
or walk-in basis at our plant and yard locations, further leveraging our footprint and lowering freight cost per pound 
and per revenue dollar. 

Our North American truck fleet incorporates approximately 1,250 trailers that are specially designed to haul 

our lightweight pipe and fittings products. These designs maximize payload versus conventional over the road 
trailers and facilitate unassisted unloading of our products at the jobsites by our drivers. The scope of fleet 
operations also includes backhaul of purchased raw materials providing a lower delivered cost to our plant locations. 

Facility Network - Our scale and extensive network of facilities provide a critical cost advantage versus our 
competitors, as we are able to more efficiently transport products to our customers and end users and to promote 
faster product shipments due to our proximity to the delivery location.

Dual Wall Corrugated Pipe - Our N-12 pipe is a dual wall HDPE pipe with a corrugated exterior for strength and a 
smooth interior wall for hydraulics and flow capacity. Our N-12 pipe competes in the storm sewer and drainage 
markets that are also served by concrete pipe. 

Our N-12 pipe is available in 17 different diameters ranging from 2” to 60” and in sections ranging from 10’ 
to 30’ in length. N-12 provides joint integrity, with integral bell and spigot joints for fast push-together installation, 
and is sold either with watertight or soil-tight coupling and fitting systems. 

Our corrugated polyethylene pipe offers many benefits including ease of installation, job-site handling and 

resistance to corrosion and abrasion. Corrugated pipe can easily be cut or coupled together, providing precise laying 
lengths while minimizing installation waste and difficulty. 

HP Storm Pipe and SaniTite HP Pipe - Our HP Storm pipe utilizes polypropylene resin, which provides 
(i) increased pipe stiffness relative to HDPE; (ii) higher Environmental Stress Crack Resistance (“ESCR”); and 
(iii) improved thermal properties, which improves joint performance. These improved physical characteristics result 
in a reduced need for select backfill, which creates installation savings for customers and expands the range of 
possible product applications. 

Our SaniTite HP pipe utilizes the same polypropylene resins as our HP Storm pipe but includes a smooth third 
exterior wall in 30” to 60” pipe. The highly engineered polypropylene resin along with the triple wall design enables 
SaniTite HP to surpass the 46 pounds per square inch (“psi”), stiffness requirement for sanitary sewer applications. 
SaniTite HP offers cost and performance advantages relative to reinforced concrete pipe (such as improved 
hydraulics and better joint integrity) and PVC pipe (such as impact resistance). 

Single Wall Corrugated Pipe - Our single wall corrugated HDPE pipe is ideal for drainage projects where flexibility, 
light weight and low cost are important. Single wall HDPE pipe products have been used for decades in agricultural 
drainage, highway edge drains, septic systems and other construction applications. In the agricultural market, 
improved technology has highlighted the favorable impact of drainage on crop yields. For homeowners, it is an 
economical and easily installed solution for downspout run-off, foundation drains, driveway culverts and general 
lawn drainage. Single wall pipe is also used for golf courses, parks and athletic fields to keep surfaces dry by 
channeling away excess underground moisture. 

Standard single wall products are available in 2” to 24” diameters and sold in varying lengths. Pipe with 2” to 

6” diameters is typically sold in coils ranging from 25’ to over 3,000’ in length, while larger diameter pipe is 
typically sold in 20’ lengths. Pipe can be either perforated or non-perforated depending on the particular drainage 
application. 

Triple Wall Corrugated Pipe and Smoothwall HDPE Pipe - Our ADS-3000 Triple Wall pipe, small diameter triple 
wall corrugated pipe, consists of a corrugated polyethylene core molded between a smooth white outer wall and a 

6 

 
 
  
  
  
  
     
  
    
    
Table of Contents 

Advanced Drainage Systems, Inc. 

smooth black inner wall. This combination of the three wall design adds strength and stiffness, while reducing 
weight as compared to PVC 2729. Triple Wall is produced in two sizes, 3” and 4”, and sold through our distribution 
network. We also manufacture smoothwall HDPE pipe in 3”, 4”, and 6” diameters that are sold into the residential 
drainage and on-site septic systems markets. 

Allied Products 

We produce a range of Allied Products that are complementary to our pipe products. Our Allied Products offer 

adjacent technologies to our core Pipe offering, presenting a complete drainage solution for our clients and 
customers. This combination of Pipe and Allied Products is a key strategy in our sales growth, profitability and 
market share penetration. The practice of selling a drainage system is attractive to both distributors and end users, by 
providing a broad package of products that can be sold on individual projects and strengthens our competitive 
advantage in the marketplace. We aggressively seek and evaluate new products, technologies and regulatory 
changes that impact our customers’ needs for Allied Products. 

Using the strength of our overall sales and distribution platform, our Allied Product strategy allows us to more 
deeply penetrate our end markets and anticipate the evolving needs of our customers. The underground construction 
industry has historically been project (not product) driven, creating the impetus for owners, engineers and 
contractors to seek manufacturers that deliver solution-based product portfolios. Many of the components of 
underground construction are related and require linear compatibility of function, regulatory approval and 
technology. 

Storm and Septic Chambers - Our StormTech chambers are used for stormwater retention, detention and “first flush” 
underground water storage on non-residential site development and public projects. These highly engineered 
chambers are injection molded from HDPE and PP resins into a proprietary design which provides strength, 
durability, and resistance to corrosion. The chambers allow for the efficient storage of stormwater volume, reducing 
the underground construction footprint and costs to the contractors, developers, and property owners. Our 
StormTech chambers offer great flexibility in design and layout of underground water storage systems. They are an 
attractive alternative to open ponds by reducing ongoing maintenance and liability and providing more useable land 
for development. Stormwater runoff is collected and stored in rows of chambers and gradually reenters the water 
system base, reducing erosion and protecting waterways. The chambers are open bottom, which allows for high 
density stacking in both storage and shipment. This freight-efficient feature drives favorable cost-competitiveness in 
serving long-distance export markets. These chamber systems typically incorporate our other product lines such as 
corrugated pipe, fabricated fittings, water quality units and geotextiles. 

Our ARC and BioDiffuser products are chambers that are used in septic systems for residential and small 

volume non-residential wastewater treatment and disposal. Rural homes and communities that do not have access 
to central sewer lines require an on-site septic solution. Our ARC and BioDiffuser chamber products are installed 
and perform their septic treatment function without gravel, reducing costs to the contractor and homeowner over 
traditional pipe and stone systems. States and municipalities have different sizing criteria for on-site septic treatment 
systems based on soil and site conditions. The innovative design of our ARC chamber is generally approved for a 
footprint reduction, further reducing the cost of the septic system. Injection-molded from HDPE, these products are 
strong, durable, and chemical-resistant. These interconnecting chambers are favored by septic contractors because 
they are lightweight, easy to install and offer articulating features which increase site-specific design flexibility. 

Structures - Our Nyloplast PVC drainage structures are used in non-residential, residential and municipal site 
development, road and highway construction, as well as landscaping, recreational, industrial and mechanical 
applications. The product family includes inline drains, drain basins, curb inlets and water control structures which 
move surface-collected stormwater vertically down to pipe conveyance systems. These custom structures are 
fabricated from sections of PVC pipe using a thermo-forming process to achieve exact site-specific hydraulic design 
requirements. Our Nyloplast products are a preferred alternative to heavier and larger concrete structures, by 
offering greater design flexibility and improved ease of installation which reduces overall project costs and 
timelines. The structures incorporate rubber gaskets to ensure watertight connections, preventing soil infiltration 
which plagues competitive products.

Advanced Drainage Systems, Inc. 

Our Inserta Tee product line consists of a PVC hub, rubber sleeve and stainless steel band. Inserta Tee is 
compression fit into the cored wall of a mainline pipe and can be used with all pipe material types and profiles. This 
product offers an easy tap-in to existing sanitary and storm sewers by limiting the excavation needed for installation 
compared to competitive products. 

Fittings - We produce fittings and couplings utilizing blow molding, injection molding and custom fabrication on 
our pipe products. Our innovative coupling and fitting products are highly complementary to our broader product 
suite, and include both soil-tight and water-tight capabilities across the full pipe diameter spectrum. Our fittings are 
sold in all end markets where we sell our current pipe products. 

Water Quality - Our BaySaver product line targets the removal of sediment, debris, oils and suspended solids 
throughout a stormwater rain event by separating and/or filtering unwanted pollutants. Our BaySeparators can be 
fabricated into multiple sizing combinations to fit a variety of applications and customer requirements. These 
products assist owners, developers and design engineers in remaining compliant with discharge requirements set 
forth by the Environmental Protection Agency (“EPA”) as well as state and local regulatory agencies. Our BaySaver 
product line coupled with our pipe, StormTech chambers, fabricated fittings, Nyloplast structures, FleXstorm inlet 
protection systems and geotextiles make up a comprehensive stormwater management solution. Our Barracuda 
separator removes sediment and other debris from storm water run-off, further protecting water resources. The 
Barracuda separator is designed to be used in a single manhole configuration and offers multiple pipe 
configurations. 

Construction Fabrics & Geotextiles - We purchase and distribute construction fabrics and other geosynthetic 
products for soil stabilization, reinforcement, filtration, separation, erosion control, and sub-surface drainage. 
Constructed of woven and non-woven PP, geotextile products provide permanent, cost-efficient site-development 
solutions. Construction fabrics and geotextiles have applications in all of our end markets. 

RAW MATERIALS AND SUPPLIERS 

Virgin HDPE and PP resins are derivatives of ethylene and propylene, respectively. Ethylene and propylene 

are derived from natural gas liquids or crude oil derivatives in the U.S. We currently purchase in excess of 
825 million pounds of virgin and recycled resin annually from over 425 suppliers in North America. As a high-
volume buyer of resin, we are able to achieve economies of scale to negotiate favorable terms and pricing. Our 
purchasing strategies differ based on the material (virgin resin versus recycled material) ordered for delivery to our 
production locations. The price movements of the different materials also vary, resulting in the need to use a number 
of strategies to reduce volatility and successfully pass on cost increases to our customer through timely selling price 
increases when needed. 

We have developed relationships with most of the North American producers of virgin high-density 
polyethylene and impact copolymer polypropylene producers that manufacture the grades we need to produce our 
products, including Braskem Americas, Inc., Chevron Phillips Chemical Co. LP, The Dow Chemical Company, 
Equistar Chemicals, LP, ExxonMobil Chemical Company, Formosa Plastics Corporation, U.S.A., Ineos Olefins & 
Polyolefins, USA, Sasol USA, and Nova Chemical. The North American capacity for ethylene derivatives has been 
expanded primarily as a result of the new supplies of natural gas liquids being produced through sustained oil and 
gas exploration and production. 

We leverage our raw material blending and processing technologies to produce an HDPE pipe that 

incorporates recycled resin. These products, which meet an ASTM International standard and an American 
Association of State Highway and Transportation Officials standard, replaces a majority of the virgin resin that is 
used with optimized recycled materials. To further develop our recycled material strategies, we established Green 
Line Polymers, Inc. (“GLP”), as our wholly-owned recycling subsidiary in 2012. GLP procures and processes 
recycled raw materials that can be used in products we produce and sell. Our first production facilities were 
established in Ohio and Georgia and are focused on processing post-industrial HDPE recycled materials. Based on 
the success of this strategy, we acquired a business that could supply clean, post-consumer recycled HDPE to our 
upper Midwest plants and established a second post-consumer processing plant, in Pennsylvania, to support our 
plants in Ohio, Michigan and the eastern and southern U.S. In fiscal 2019, 91% of our non-virgin HDPE raw 
material needs were internally processed (enhanced) through our GLP operations. 

8 

 
 
Table of Contents 

Advanced Drainage Systems, Inc. 

We maintain relationships with several of the largest environmental companies such as Waste Management, 

Inc., Republic Services, Inc., and Rumpke, Inc., which provide us with post-consumer HDPE recycled materials. We 
also maintain relationships with several key post-industrial HDPE suppliers, including Performance Materials NA, 
Inc. (formerly E.I. du Pont de Nemours and Company), Silgan Plastics, Consolidated Container Company and Alpla, 
Inc., which provide us with materials that cannot otherwise be utilized in their respective production processes. 

We are one of the largest domestic recyclers of HDPE. We believe that we are well positioned for future 

growth as we add additional recycled material processing facilities, add capacity to existing facilities, and expand 
our supplier base for virgin resin. We anticipate continued growth in the availability of ethylene and propylene 
which are used to manufacture HDPE and PP, respectively. 

CUSTOMERS 

We have a large, active customer base of approximately 20,000 customers, with two customers representing 
10% or more of fiscal 2019 net sales. Ferguson Enterprises (“Ferguson”) accounted for 13.8% and Core and Main 
accounted for 11.6% of fiscal 2019 net sales. Our customer base is diversified across the range of end markets that 
we serve. 

A majority of our sales are made through distributors, including many of the largest national and independent 
waterworks distributors, with whom we have long-standing distribution relationships. These include Ferguson and 
Core and Main who sell primarily to the storm sewer and sanitary sewer markets. We also utilize a network of 
hundreds of small to medium-sized independent distributors across the United States. We have strong relationships 
with major national retailers that carry drainage products, including The Home Depot, Lowe’s, Ace Hardware and 
Do it Best. We offer the most complete line of HDPE products in the industry and are the only national 
manufacturer that can service the “Big-Box” retailers from coast-to-coast. We also sell to buying groups and co-ops 
in the United States that serve the plumbing, hardware, irrigation and landscaping markets. Selling to buying groups 
and co-ops provides us a further presence on a national, regional and local basis for the distribution of our products. 
Our preferred vendor status with these groups allows us to reach thousands of locations in an effective manner. 
Members of these groups and co-ops generally are independent businesses with strong relationships and brand 
recognition with smaller contractors and homeowners in their local markets. The combination of our large sales 
force, long-standing retail and contractor customer relationships and extensive network of manufacturing and 
distribution facilities complements and strengthens our broad customer and market coverage. 

Our customer service organization of more than 130 employees is supplemented by the employees of our 
manufacturing plants, distribution centers and drivers of our tractor-trailers. We staff and operate three regional 
customer service call centers. In conjunction with our field sales and engineering team, this highly trained and 
competent staff allows us to maintain more customer touch points and interaction than any of our competitors. 

SALES AND MARKETING 

We have one of the largest and most experienced sales and engineering forces in the industry, with more than 
400 sales and engineering professionals. Offering the broadest product line in the industry enables our sales force to 
source the greatest number of new opportunities and more effectively cross-sell products than any of our 
competitors. We consistently maintain thousands of touch points with customers, civil engineers and municipal 
authorities, continuously educating them on new product innovations and their advantages relative to traditional 
products. We believe we are the industry leader in these efforts, and we view this work as an important part of our 
marketing strategy, particularly in promoting N-12 and SaniTite HP for storm and sanitary sewer systems, as 
regulatory approvals are essential to the specification and acceptance of these product lines. 

Our sales and marketing strategy is divided into four components — comprehensive market coverage, diverse 

product offerings, readily-available local inventory and specification efforts. Our goal is to provide the 
distributor/owner with the most complete, readily available product line in our industry. We strive to use our 
manufacturing footprint, product portfolio and market expertise to efficiently service our customers. 

Our sales and engineering objective is to influence, track and quote all selling opportunities as early in the 
project life cycle as possible. We strive to be meaningfully involved in all phases of the project cycle, including

design, bidding, award and installation. Conceptual project visibility allows sales and engineering professionals the 
ability to influence design specifications and increase the probability of inclusion of our products in bid documents. 
The inclusion of our products in bid documents improves the probability of completing the sale. On-demand 
installation support allows us to maintain customer relationships and ensure positive installation experience. In 
addition to direct channel customers, we also maintain and develop relationships with federal agencies, municipal 
agencies, national standard regulators, private consulting engineers and architects. Our consistent interaction with 
these market participants enables us to continue our market penetration. This ongoing dialogue has positioned us as 
an industry resource for design guidance and product development and as a respected expert in water management 
solutions. 

SEASONALITY 

Historically, sales of our products have been higher in the first and second quarters of each fiscal year due to 
favorable weather and longer daylight conditions accelerating construction activity during these periods. Seasonal 
variations in operating results may also be impacted by inclement weather conditions, such as cold or wet weather, 
which can delay projects. 

In the non-residential, residential and infrastructure markets in the northern United States and Canada, 
construction activity typically begins to increase in late March and is slower in December, January and February. In 
the southern and western United States, Mexico, Central America and South America, the construction markets are 
less seasonal. The agricultural drainage market is concentrated in the early spring just prior to planting and in the fall 
just after crops are harvested prior to freezing of the ground in winter.

COMPETITION 

We operate in a highly fragmented industry and hold leading positions in multiple market sectors. 
Competition, including our competitors and specific competitive factors, varies for each market sector. 

We believe the principal competitive factors for our market sectors include local selling coverage, product 

availability, breadth and cost of products, technical knowledge and expertise, customer and supplier relationships, 
reliability and accuracy of service, effective use of technology, delivery capabilities and timeliness, pricing of 
products, and the provision of credit. We believe that our competitive strengths and strategy allow us to compete 
effectively in our market sectors. 

The stormwater drainage industry, in particular, is highly fragmented with many smaller specialty and 
regional competitors providing a variety of product technologies and solutions. We compete against concrete pipe, 
corrugated steel pipe and PVC pipe producers on a national, regional and local basis. In addition, there are many 
HDPE pipe producers in the United States. 

In the United States, our primary competitors are concrete pipe producers, including Quikrete, Forterra and 
Oldcastle CRH Precast, as well as smaller, regional competitors. In the corrugated steel pipe sector, our primary 
national competitor is Contech Engineered Solutions, and we compete with Lane Enterprises, Pacific Corrugated 
and Southeast Culvert on a regional level, as well as other smaller competitors. In the PVC pipe sector, we compete 
primarily with JM Eagle, Diamond Plastics and North American Pipe. We believe we are the only corrugated HDPE 
pipe producer with a national footprint, and our competitors operate primarily on a regional and local level. In the 
corrugated HDPE pipe sector in the United States, our primary competitors on a regional basis are JM Eagle, Lane 
Enterprises and Prinsco.

INTELLECTUAL PROPERTY 

We rely upon a combination of patents, trademarks, trade names, licensing arrangements, trade secrets, know-

how and proprietary technology in order to secure and protect our intellectual property rights, both in the United 
States and in foreign countries. 

We seek to protect our new technologies with patents and trademarks and defend against patent infringement 

allegations. We hold a significant amount of intellectual property rights pertaining to product patents, process 
patents and trademarks. We continually seek to expand and improve our existing product offerings through product 
development and acquisitions. Although our intellectual property is important to our business operations and in the 
aggregate constitutes a valuable asset, we do not believe that any single patent, trademark or trade secret is critical to 
the success of our business as a whole. We cannot be certain that our patent applications will be issued or that any 
issued patents will provide us with any competitive advantages or will not be challenged by third parties. 

In addition to the foregoing protections, we generally control access to and use of our proprietary and other 
confidential information through the use of internal and external controls, including contractual protections with 
employees, distributors and others. See “Item 1A. Risk Factors — Risks Relating to Our Business — If we are 
unable to protect our intellectual property rights, or we infringe on the intellectual property rights of others, our 
ability to compete could be negatively impacted.” 

EMPLOYEES 

As of March 31, 2019, in our domestic and international operations the Company and its consolidated 

subsidiaries had approximately 4,400 employees, consisting of approximately 3,000 hourly personnel and 
approximately 1,400 salaried employees. As of March 31, 2019, approximately 250 hourly personnel in our 
Mexican joint venture were covered by collective bargaining agreements. 

REGULATION 

Our operations are affected by various statutes, regulations and laws in the markets in which we operate, 
which historically have not had a material effect on our business. We are subject to various laws applicable to 
businesses generally, including laws affecting land usage, zoning, the environment, health and safety, transportation, 
labor and employment practices, competition, immigration and other matters. Additionally, building codes may 
affect the products our customers are allowed to use, and, consequently, changes in building codes may affect the 
salability of our products. The transportation and disposal of many of our products are also subject to federal 
regulations. The U.S. Department of Transportation (“U.S. DOT”) regulates our operations in domestic interstate 
commerce. We are subject to safety requirements governing interstate operations prescribed by the U.S. DOT. 
Vehicle dimensions and driver hours of service also remain subject to both federal and state regulation. 

We have been able to consistently capitalize on changes in both local and federal regulatory statutes relating to 

storm and sanitary sewer construction, repair and replacement. Most noteworthy is the Federal Clean Water Act of 
1972 and the subsequent EPA Phase I, II and sustainable infrastructure regulations relating to storm sewer 
construction, storm water quantity, storm water quality, and combined sewer separation. Our diversity of products 
offering a solution-based selling approach coupled with detailed market knowledge makes us an integral industry 
resource in both regulatory changes and compliance. 

An important element of our growth strategy has been our focus on industry education efforts to drive 

regulatory approvals for our core HDPE products at national, state and local levels. We employ a team of 
approximately 60 field-based engineers who work closely with government agencies to obtain regulatory approvals 
for our products, and also with civil engineering firms to specify our products on non-residential construction and 
road-building projects. With the introduction of our HP storm and sanitary pipe, we have refocused our efforts 
calling on state departments of transportation to enhance their approval of our pipe products. Additional state and 
local regulatory approvals will continue to present new growth opportunities in new and existing geographic markets 
for us. The trend of substituting traditional materials for HDPE and PP is expected to continue as more states and 
municipalities recognize the benefits of our HDPE N-12 pipe and our polypropylene HP pipe by approving it for use 
in a broader range of applications.

ENVIRONMENTAL, HEALTH AND SAFETY MATTERS 

We are subject to a broad range of foreign, federal, state and local environmental, health and safety laws and 

regulations, including those pertaining to air emissions, water discharges, the handling, disposal and transport of 
solid and hazardous materials and wastes, the investigation and remediation of contamination and otherwise relating 
to health and safety and the protection of the environment and natural resources. To a limited extent, our current and 
past operations, and those of many of the companies we have acquired, involve materials that are, or could be 
classified as, toxic or hazardous. There is inherent risk of contamination and environmental damage in our 
operations and the products we handle, transport and distribute. See “Item 1A. Risk Factors — Risks Relating to Our 
Business — We could incur significant costs in complying with environmental, health and safety laws or permits or 
as a result of satisfying any liability or obligation imposed under such laws or permits.”

Item 1A. 

Risk Factors 

Please carefully consider the risks described below, together with all other information included or 
incorporated by reference in this Annual Report on Form 10-K. If any of the following risks actually occur, our 
business, financial condition, results of operations and cash flows could be materially adversely affected. In these 
circumstances, the market price of our common stock could decline significantly. 

Risks Relating to Our Business 

Fluctuations in the price and availability of resins, our principal raw materials, and our inability to obtain 
adequate supplies of resins from suppliers and pass on resin price increases to customers could adversely affect 
our business, financial condition, results of operations and cash flows. 

The principal raw materials that we use in our high performance thermoplastic corrugated pipe and Allied 

Products are virgin and recycled resins. Our ability to operate profitably depends, to a large extent, on the markets 
for these resins. In particular, as resins are derived either directly or indirectly from crude oil derivatives and natural 
gas liquids, resin prices fluctuate substantially as a result of changes in crude oil and natural gas prices, changes in 
existing processing capabilities and the capacity of resin suppliers. The petrochemical industry historically has been 
cyclical and volatile. The cycles are generally characterized by periods of tight supply, followed by periods of 
oversupply, primarily resulting from significant capacity additions. Unanticipated changes in and disruptions to 
existing petrochemical capacities could also significantly increase resin prices, often within a short period of time, 
even if crude oil and natural gas prices remain low. 

Our ability to offer our core products depends on our ability to obtain adequate resins, which we purchase 
directly from major petrochemical and chemical suppliers. We maintain supply agreements with our major resin 
suppliers that provide multi-year terms and volumes that are in excess of our projected consumption. For our 

12 

 
 
Table of Contents 

Advanced Drainage Systems, Inc. 

polypropylene virgin resin price exposure, we utilize financial hedges of propylene as a proxy for polypropylene. 
Historically, the month to month change in market-based pricing has been very similar between propylene and 
polypropylene. The loss of, or substantial decrease in the availability of, raw materials from our suppliers, or the 
failure by our suppliers to continue to provide us with raw materials on commercially reasonable terms, or at all, 
could adversely affect our business, financial condition, results of operations and cash flows. In addition, supply 
interruptions could arise from labor disputes or weather conditions affecting supplies or shipments, transportation 
disruptions or other factors beyond our control. An extended disruption in the timely availability of raw materials 
from our key suppliers would result in a decrease in our revenues and profitability. 

Our ability to maintain profitability heavily depends on our ability to pass through to our customers the full 

amount of any increase in raw material costs, which are a large portion of our overall product costs. We may be 
unable to do so in a timely manner, or at all, due to competition in the markets in which we operate. In addition, 
certain of our largest customers historically, have exerted significant pressure on their outside suppliers to keep 
prices low because of their market share. If increases in the cost of raw materials cannot be passed on to our 
customers, or the duration of time associated with a pass through becomes extended, our business, financial 
condition, results of operations and cash flows will be adversely affected. 

Any disruption or volatility in general business and economic conditions in the markets in which we operate 
could have a material adverse effect on the demand for our products and services. 

The markets in which we operate are sensitive to general business and economic conditions in the 

United States and worldwide, including availability of credit, interest rates, fluctuation in capital and business and 
consumer confidence. These conditions, combined with price fluctuations in crude oil derivatives and natural gas 
liquids, declining business and consumer confidence and increased unemployment, precipitated an economic 
slowdown and severe recession in recent years. The difficult conditions in these markets and the overall economy 
affect our business in a number of ways. For example: 

• 

• 

• 

• 

The volatility of the United States economy in general can have an adverse effect on our sales that are 
dependent on the non-residential construction market. Continued uncertainty about current economic 
conditions to pose a risk to our business units that serve the non-residential construction market, as 
participants in this industry may postpone spending in response to tighter credit, negative financial news 
and/or declines in income or asset values, which could have a continued material adverse effect on the 
demand for our products and services. 

Our business depends to a great extent upon general activity levels in the agriculture market. Changes in 
corn production, soybean production, farm income, farmland value and the level of farm output in the 
geographic locations in which we operate are all material factors that could adversely affect the 
agriculture market and result in a decrease in the amount of products that our customers purchase. The 
nature of the agriculture market is such that a downturn in demand can occur suddenly, resulting in 
excess inventories, un-utilized production capacity and reduced prices for pipe products. These 
downturns may be prolonged, and our revenue and profitability would be harmed. 

The homebuilding industry underwent a significant decline after its peak in 2005. While new housing 
starts demonstrated a compounded annual growth rate of 6.2% from 2013 to 2018, current levels remain 
below the long-term average of 1.4 million starts since the U.S. Census Bureau began reporting the data 
demand for our products and services in this market, which in turn had a significant adverse effect on 
our financial condition and results of operations. 

Demand for our products and services depend to a significant degree on spending on infrastructure, 
which is inherently cyclical. Infrastructure spending is affected by a variety of factors beyond our 
control, including interest rates, availability and commitment of public funds for municipal spending 
and highway spending and general economic conditions. Our products sales may be adversely impacted 
by budget cuts by governments, including as a result of lower than anticipated tax revenues. 

All of our markets are sensitive to changes in the broader economy. Downturns or lack of substantial 

improvement in the economy in any region in which we operate have adversely affected and could continue to 
adversely affect our business, financial condition and results of operations. While we operate in many markets, our 

13 

 
 
Table of Contents 

Advanced Drainage Systems, Inc. 

business is particularly impacted by changes in the economies of the United States, Canada and Mexico, which 
represented 88.4%, 6.8% and 3.5%, respectively, of our net sales for fiscal 2019 and collectively represented 98.7% 
of our net sales for fiscal 2019. 

We cannot predict the duration of current economic conditions, or the timing or strength of any future 
recovery of activities in our markets. Continued weakness in the market in which we operate could have a material 
adverse effect on our business, financial condition, results of operations and cash flows. We may have to close 
under-performing facilities from time to time as warranted by general economic conditions and/or weakness in the 
markets in which we operate. In addition to a reduction in demand for our products, these factors may also reduce 
the price we are able to charge for our products and restrict our ability to pass raw material cost increases to our 
customers. This, combined with an increase in excess capacity, will negatively impact our profitability, cash flows 
and our financial condition, generally. 

Demand for our products and services could decrease if we are unable to compete effectively, and our success 
depends largely on our ability to convert current demand for competitive products into demand for our products. 

We compete with both manufacturers of high performance thermoplastic corrugated pipe and manufacturers 
of alternative products, such as concrete, steel and PVC pipe products, on the basis of a number of considerations, 
including product characteristics such as durability, design, ease of installation, price on a price-to-value basis and 
service. In particular, we compete on a global, national and local basis with pipe products made of traditional 
materials which our high performance thermoplastic corrugated pipe products are designed to replace. For example, 
our N-12 and SaniTite HP products face competition from concrete, steel and PVC pipe products in the small- and 
large-diameter size segments of the market. 

Our ability to successfully compete and grow depends largely on our ability to continue to convert the current 
demand for concrete, steel and PVC pipe products into demand for our high performance thermoplastic corrugated 
pipe and Allied Products. Our thermoplastic pipe typically has an installed cost advantage of approximately 20% 
over concrete pipe. However, depending upon certain factors such as the size of the pipe, the geography of a 
particular location and then-existing raw material costs, the initial cost of our thermoplastic pipe may be higher than 
the initial cost of alternative products such as concrete, steel and PVC pipe products. To increase our market share, 
we will need to increase material conversion by educating our customers about the value of our products in 
comparison to existing alternatives, particularly on an installed cost basis, working with government agencies to 
expand approvals for our products and working with civil engineering firms which may influence the specification 
of our products on construction projects. No assurance can be given that our efforts to increase or maintain the 
current rate of material conversion will be successful, and our failure to do so would have a material adverse effect 
on our business, financial condition, results of operations and cash flows. 

We also expect that new competitors may develop over time. No assurance can be given that we will be able 

to respond effectively to such competitive pressures. Increased competition by existing and future competitors could 
result in reductions in sales, prices, volumes and gross margins that would materially adversely affect our business, 
financial condition, results of operations and cash flows. Furthermore, our success will depend, in part, on our 
ability to maintain our market share and gain market share from competitors. 

Certain of our competitors have financial and other resources that are greater than ours and may be better able 
to withstand price competition, especially with respect to traditional products. In addition, consolidation by industry 
participants could result in competitors with increased market share, larger customer bases, greater diversified 
product offerings and greater technological and marketing expertise, which would allow them to compete more 
effectively against us. Moreover, our competitors may develop products that are superior to our products or may 
adapt more quickly to new technologies or evolving customer requirements. Technological advances by our 
competitors may lead to new manufacturing techniques and make it more difficult for us to compete. In many 
markets in which we operate there are no significant entry barriers that would prevent new competitors from 
entering the market, especially on the local level, or existing competitors from expanding in the market. In addition, 
because we do not have long-term arrangements with many of our customers, these competitive factors could cause 
our customers to cease purchasing our products. 

14

Advanced Drainage Systems, Inc. 

In addition, our contracts with municipalities are often awarded and renewed through periodic competitive 

bidding. We may not be successful in obtaining or renewing these contracts on financially attractive terms or at all, 
which could adversely affect our business, financial condition, results of operations and cash flows. 

Our results of operations could be adversely affected by the effects of weather. 

Although weather patterns affect our operating results throughout the year, adverse weather historically has 

reduced construction activity in our third and fourth fiscal quarters. In contrast, our highest volume of net sales 
historically has occurred in our first and second fiscal quarters. 

Most of our business units experience seasonal variation as a result of the dependence of our customers on 

suitable weather to engage in construction projects. Generally, during the winter months, construction activity 
declines due to inclement weather, frozen ground and shorter daylight hours. In addition, to the extent that 
hurricanes, severe storms, floods, other natural disasters or similar events occur in the geographic regions in which 
we operate, our results of operations may be adversely affected. We anticipate that fluctuations of our operations 
results from period to period due to seasonality will continue in the future. 

The loss of any of our significant customers could adversely affect our business, financial condition, results of 
operations and cash flows. 

Our ten largest customers generated approximately 40% of our net sales in fiscal 2019. We cannot guarantee 

that we will maintain or improve our relationships with these customers or that we will continue to supply these 
customers at historical levels. Because we do not have long-term arrangements with many of our customers, such 
customers may cease purchasing our products without notice or upon short notice to us. During the economic 
downturn, some of our customers reduced their operations. For example, some homebuilder customers exited or 
severely curtailed building activity in certain of our markets. There is no assurance that our customers will increase 
their activity level or return it to historic levels. A slow economic recovery could continue to have material adverse 
effect on our business, financial condition, results of operations and cash flows. 

In addition, consolidation among customers could also result in a loss of some of our present customers to our 
competitors. The loss of one or more of our significant customers, a significant customer’s decision to purchase our 
products in significantly lower quantities than they have in the past, or deterioration in our relationship with any of 
them could have a material adverse effect on our business, financial condition, results of operations and cash flows. 

The majority of our net sales are credit sales which are made primarily to customers whose ability to pay is 
dependent, in part, upon the economic strength of the industry and geographic areas in which they operate, 
including recent changes in U.S. tax laws, and the failure to collect monies owed from customers could adversely 
affect our financial condition. 

The majority of our net sales volume is facilitated through the extension of credit to our customers whose 

ability to pay is dependent, in part, upon the economic strength of the industry in the areas where they operate. Our 
business units offer credit to customers, either through unsecured credit that is based solely upon the 
creditworthiness of the customer, or secured credit for materials sold for a specific job where the security lies in lien 
rights associated with the material going into the job. The type of credit offered depends both on the financial 
strength of the customer and the nature of the business in which the customer is involved. End users, resellers and 
other non-contractor customers generally purchase more on unsecured credit than secured credit. The inability of our 
customers to pay off their credit lines in a timely manner, or at all, would adversely affect our business, financial 
condition, results of operations and cash flows. Furthermore, our collections efforts with respect to non-paying or 
slow-paying customers could negatively impact our customer relations going forward. 

Because we depend on the creditworthiness of certain of our customers, if the financial condition of our 

customers declines, our credit risk could increase. Significant contraction in our markets, coupled with tightened 
credit availability and financial institution underwriting standards, could adversely affect certain of our customers. 
Should one or more of our larger customers declare bankruptcy, it could adversely affect the collectability of our 
accounts receivable, bad debt reserves and net income.

Our international operations expose us to political, economic and regulatory risks not normally faced by 
businesses that operate only in the United States. 

International operations are exposed to different political, economic and regulatory risks that are not faced by 

businesses that operate solely in the United States. Some of our operations are outside the United States, with 
manufacturing and distribution facilities in Canada and several Latin American countries. Our international 
operations are subject to risks similar to those affecting our operations in the United States in addition to a number 
of other risks, including: difficulties in enforcing contractual and intellectual property rights; impositions or 
increases of withholding and other taxes on remittances and other payments by subsidiaries and affiliates; exposure 
to different legal standards; fluctuations in currency exchange rates; impositions or increases of investment and other 
restrictions by foreign governments; the requirements of a wide variety of foreign laws; political and economic 
instability; war; and difficulties in staffing and managing operations, particularly in remote locations. 

As a result of our international operations, we could be adversely affected by violations of the U.S. Foreign 
Corrupt Practices Act and similar foreign anti-corruption laws. 

The U.S. Foreign Corrupt Practices Act (“FCPA”) and similar foreign anti-corruption laws generally prohibit 

companies and their intermediaries from making improper payments or providing anything of value to wrongfully 
influence foreign government officials for the purpose of obtaining or retaining business or obtaining an unfair 
advantage, and generally require companies to maintain accurate books and records and internal controls, including 
at foreign controlled subsidiaries. Recent years have seen a substantial increase in the global enforcement of anti-
corruption laws, with more frequent voluntary self-disclosures by companies, aggressive investigations and 
enforcement proceedings by both the U.S. Department of Justice and the SEC resulting in record fines and penalties, 
increased enforcement activity by non-U.S. regulators, and increases in criminal and civil proceedings brought 
against companies and individuals. 

We have operations in Canada as well as existing joint ventures in Mexico and South America. Our internal 

policies provide for compliance with all applicable anti-corruption laws for both us and for our joint venture 
operations. Our continued operation and expansion outside the United States, including in developing countries, 
could increase the risk of such violations in the future. Despite our training and compliance programs, our internal 
control policies and procedures may not always protect us from unauthorized, reckless or criminal acts committed 
by our employees, agents or joint venture partners. 

Conducting a portion of our operations through joint ventures exposes us to risks and uncertainties, many of 
which are outside of our control, and such risks could have a material adverse effect on our business, financial 
condition, results of operations and cash flows. 

With respect to our existing joint ventures, any differences in views among the joint venture participants may 

result in delayed decisions or in failures to agree on major issues. We also cannot control the actions of our joint 
venture partners, including any nonperformance, default or bankruptcy of our joint venture partners. As a result, we 
may be unable to control the quality of products produced by the joint ventures or achieve consistency of product 
quality as compared with our other operations. In addition to net sales and market share, this may have a material 
negative impact on our brand and how it is perceived thereafter. Moreover, if our partners also fail to invest in the 
joint venture in the manner that is anticipated or otherwise fail to meet their contractual obligations, the joint 
ventures may be unable to adequately perform and conduct their respective operations, requiring us to make 
additional investments or perform additional services to ensure the adequate performance and delivery of products 
and/or services to the joint ventures’ customers, which could have a material adverse effect on our business, 
financial condition, results of operations and cash flows. 

We may not be able to successfully expand into new product or geographic markets, which could negatively 
impact our future sales and results of operations. 

We may expand into new product markets based on our existing manufacturing, design and engineering 

capabilities and services. Our business depends in part on our ability to identify future products and product lines 
that complement existing products and product lines and that respond to our customers’ needs. We may not be able 
to compete effectively unless our product selection keeps up with trends in the markets in which we compete or 
trends in new products. In addition, our ability to integrate new products and product lines into our distribution 

16 

 
 
Table of Contents 

Advanced Drainage Systems, Inc. 

network could impact our ability to compete. Furthermore, the success of new products and new product lines will 
depend on market demand and there is a risk that new products and new product lines will not deliver expected 
results, which could negatively impact our future sales and results of operations. 

Our expansion into new geographic markets may present competitive, distribution and regulatory challenges 

that differ from current ones. We may be less familiar with the target customers and may face different or additional 
risks, as well as increased or unexpected costs, compared to existing operations. Expansion into new geographic 
markets may also bring us into direct competition with companies with whom we have little or no past experience as 
competitors. To the extent we rely upon expansion into new geographic markets for growth and do not meet the new 
challenges posed by such expansion, our future sales growth could be negatively impacted, our operating costs could 
increase, and our business operations and financial results could be adversely affected. 

We may not achieve the acquisition component of our growth strategy, which could negatively impact our 
financial condition and results of operations. 

Acquisitions are an important component of our growth strategy; however, there can be no assurance that we 

will be able to continue to grow our business through acquisitions as we have done historically or that any 
businesses acquired will perform in accordance with expectations or that business judgments concerning the value, 
strengths and weaknesses of businesses acquired will prove to be correct. Future acquisitions may result in the 
incurrence of debt and contingent liabilities, an increase in interest expense and amortization expense and significant 
charges relative to integration costs. Our strategy could be impeded if we do not identify suitable acquisition 
candidates and our financial condition and results of operations will be adversely affected if we are unable to 
properly evaluate acquisition targets. 

Acquisitions involve a number of special risks, including: problems implementing disclosure controls and 

procedures for the newly acquired business; unforeseen difficulties extending internal control over financial 
reporting and performing the required assessment at the newly acquired business; potential adverse short-term 
effects on operating results through increased costs or otherwise; diversion of management’s attention and failure to 
recruit new, and retain existing, key personnel of the acquired business; failure to successfully implement 
infrastructure, logistics and systems integration; our business growth could outpace the capability of our systems; 
and the risks inherent in the systems of the acquired business and risks associated with unanticipated events or 
liabilities, any of which could have a material adverse effect on our business, financial condition and results of 
operations. In addition, we may not be able to obtain financing necessary to complete acquisitions on attractive 
terms or at all. 

Increased fuel and energy prices, and our inability to obtain sufficient quantities of fuel to operate our in-house 
delivery fleet, could adversely affect our business, financial condition, results of operations and cash flows. 

Energy and petroleum prices have fluctuated significantly in recent years. Prices and availability of petroleum 

products are subject to political, economic and market factors that are outside our control. Political events in 
petroleum-producing regions as well as hurricanes and other weather-related events may cause the price of fuel to 
increase. 

We consume a large amount of energy and petroleum products in our operations, including the manufacturing 

process and delivering a significant volume of products to our customers by our in-house fleet. While we utilize a 
diesel hedging program associated with our in-house fleet to mitigate against higher fuel prices, our operating profit 
will be adversely affected if we are unable to obtain the energy and fuel we require or to fully offset the anticipated 
impact of higher energy and fuel prices through increased prices or surcharges to our customers or through other 
hedging strategies. If shortages occur in the supply of energy or necessary petroleum products and we are not able to 
pass along the full impact of increased energy or petroleum prices to our customers, our business, financial 
condition, results of operations and cash flows would be adversely affected. 

We have substantial fixed costs and, as a result, our income from operations is sensitive to changes in our net 
sales. 

A significant portion of our expenses are fixed costs, including personnel. Consequently, a decline in our net 
sales could have a greater percentage effect on our income from operations if we do not act to reduce personnel or 

17 

 
 
Table of Contents 

Advanced Drainage Systems, Inc. 

take other fixed cost reduction actions. Moreover, a key element of our strategy is managing our assets, including 
our substantial fixed assets, more effectively, including through sales or other disposals of excess assets. Our failure 
to rationalize our fixed assets in the time, and within the costs, we expect could have a material adverse effect on our 
business, financial condition, results of operations and cash flows. 

Internally manufacturing our products at our own facilities subjects our business to risks associated with 
manufacturing processes. 

We internally manufacture our own products at our facilities. While we maintain insurance covering our 

manufacturing and production facilities and have significant flexibility to manufacture and ship our own products 
from various facilities, a catastrophic loss of the use of certain of our facilities due to accident, fire, explosion, labor 
issues, weather conditions, other natural disaster or otherwise, whether short or long-term, could have a material 
adverse effect on our business, financial condition, results of operations and cash flows. 

Unexpected failures of our equipment and machinery may result in production delays, revenue loss and 
significant repair costs, injuries to our employees, and customer claims. Any interruption in production capability 
may limit our ability to supply enough products to customers and may require us to make large capital expenditures 
to remedy the situation, which could have a negative impact on our profitability and cash flows. Our business 
interruption insurance may not be sufficient to offset the lost revenues or increased costs that we may experience 
during a disruption of our operations. 

We provide product warranties that could expose us to claims, which could in turn damage our reputation and 
adversely affect our business, financial condition, results of operations and cash flows. 

We generally provide limited product warranties on our products against defects in materials and 

workmanship in normal use and service. Most of our pipe products have a warranty that is not limited in duration. 
The warranty period for other products such as our StormTech chambers, our Inserta Tee product line, our BaySaver 
product line and our FleXstorm inlet protection systems is generally one year. Estimating the required warranty 
reserves requires judgment. Management estimates warranty reserves based in part upon historical warranty costs. 
Management also considers various relevant factors, including its stated warranty policies and procedures, as part of 
its evaluation of its liability. Because warranty issues may surface later in the product life cycle, management 
continues to review these estimates on a regular basis and considers adjustments to these estimates based on actual 
experience compared to historical estimates. Although management believes that our warranty reserves as of 
March 31, 2019 are adequate, actual results may vary from these estimates. 

The nature of our business exposes us to construction defect and product liability claims as well as other legal 
proceedings, which could damage our reputation and adversely affect our business, financial condition, results of 
operations and cash flows. 

We are exposed to construction defect and product liability claims relating to our various products if our 

products do not meet customer expectations. Such liabilities may arise out of the quality of raw materials we 
purchase from third-party suppliers, over which we do not have direct control. We also operate a large fleet of trucks 
and other vehicles and therefore face the risk of traffic accidents. 

While we currently maintain insurance coverage to address a portion of these types of liabilities, we cannot 

make assurances that we will be able to obtain such insurance on acceptable terms in the future, if at all, or that any 
such insurance will provide adequate coverage against potential claims. Further, while we intend to seek 
indemnification against potential liability for products liability claims from relevant parties, we cannot guarantee 
that we will be able to recover under any such indemnification agreements. Product liability claims can be expensive 
to defend and can divert the attention of management and other personnel for significant time periods, regardless of 
the ultimate outcome. An unsuccessful product liability defense could be highly costly and accordingly result in a 
decline in revenues and profitability. In addition, even if we are successful in defending any claim relating to the 
products we distribute, claims of this nature could negatively impact customer confidence in us and our products. 

From time to time, we are also involved in government inquiries and investigations, as well as consumer, 
employment, tort proceedings and other litigation. We cannot predict with certainty the outcomes of these legal 
proceedings and other contingencies, including potential environmental remediation and other proceedings 

18

commenced by government authorities. The outcome of some of these legal proceedings and other contingencies 
could require us to take actions which would adversely affect our operations or could require us to pay substantial 
amounts of money. Additionally, defending against these lawsuits and proceedings may involve significant expense 
and diversion of management’s attention and resources from other matters. 

Because our business is working capital intensive, we rely on our ability to manage our supply purchasing and 
customer credit policies. 

Our operations are working capital intensive, and our inventories, accounts receivable and accounts payable 

are significant components of our net asset base. We manage our inventories and accounts payable through our 
purchasing policies and our accounts receivable through our customer credit policies. If we fail to adequately 
manage our supply purchasing or customer credit policies, our working capital and financial condition may be 
adversely affected. 

The restatements of our previously issued financial statements and the related claims, investigations and 
proceedings arising out of the Prior Restatement have been time-consuming and expensive and could expose us 
to additional risks that would adversely affect our financial position, results of operations and cash flows. 

As described in our Annual Report on Form 10-K for the fiscal year ended March 31, 2015 (the “Fiscal 2015 
Form 10-K”), we restated our previously issued consolidated financial statements for the first three fiscal quarters in 
fiscal 2015 (the “Prior Restatement”). In addition, as described in our Annual Report on Form 10-K/A for the fiscal 
year ended March 31, 2016 (the “Fiscal 2016 Form 10-K”), we restated our previously issued consolidated financial 
statements for the fiscal years ended March 31, 2016 and 2015 as well as each of the quarters in fiscal 2016 and 
2015 (the “Stock-Based Compensation Restatement”). Both the Prior Restatement and the Stock-Based 
Compensation Restatement were time-consuming and expensive and could continue to expose us to a number of 
additional risks that would adversely affect our financial position, results of operations and cash flows. In particular, 
we incurred significant expense, including audit, legal, consulting and other professional fees in connection with the 
Prior Restatement and the Stock-Based Compensation Restatement. Expenses incurred during fiscal 2018 and 2017 
as a result of the Prior Restatements were approximately $4 million and $24 million, respectively. In fiscal 2019, we 
recorded a $1.9 million benefit as a result of insurance proceeds received. Furthermore, we have also incurred 
significant expenses in connection with the remediation of the weaknesses in our internal control over financial 
reporting as part of the Prior Restatements as well as incurring significant expenses in connection with hiring 
additional personnel in order to increase the finance department. Any future restatement of our financial statements 
would adversely affect our financial position, results of operations and cash flows. 

Our failure to maintain effective disclosure controls and internal control over financial reporting could adversely 
affect our business, financial position and results of operations. 

We are required to evaluate the effectiveness of our disclosure controls on a periodic basis and publicly 

disclose the results of these evaluations and related matters in accordance with the requirements of Section 404 of 
the Sarbanes-Oxley Act of 2002. As of March 31, 2019, we have identified a material weakness in internal control 
over financial reporting. The material weakness in our internal control over financial reporting as of March 31, 2019 
was a result of a material weakness in the control environment of our consolidated joint venture affiliate, ADS 
Mexicana. See Item 9A. “Controls and Procedures” for further description. 

A “material weakness” is a deficiency, or a combination of deficiencies, in internal control over financial 

reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim 
consolidated financial statements will not be prevented or detected on a timely basis. We are actively engaged in 
remediation activities designed to address the material weakness, but our remediation efforts are not complete and 
are ongoing. Although we are working to remedy the ineffectiveness of the Company’s internal control over 
financial reporting, there can be no assurance as to when the remediation plan will be fully implemented or the 
aggregate cost of implementation. Until our remediation plan is fully implemented, our management will continue to 
devote significant time and attention to these efforts. If we do not complete our remediation in a timely fashion, or at 
all, or if our remediation plan is inadequate, there will continue to be an increased risk that we will be unable to 
timely file future periodic reports with the SEC and that our future consolidated financial statements could contain 
errors that will be undetected. If we are unable to report our results in a timely and accurate manner, we may not be 
able to comply with the applicable covenants in our financing arrangements, and may be required to seek additional 

19 

 
 
Table of Contents 

Advanced Drainage Systems, Inc. 

amendments or waivers under these financing arrangements, which could adversely impact our liquidity and 
financial condition. Further and continued determinations that there is a material weakness in the effectiveness of the 
Company’s internal control over financial reporting could reduce our ability to obtain financing or could increase 
the cost of any financing we obtain and require additional expenditures of both money and our management’s time 
to comply with applicable requirements. 

Any failure to implement or maintain required new or improved controls, or any difficulties we encounter in 

their implementation, could result in additional material weaknesses or material misstatement in our consolidated 
financial statements. Any new misstatement could result in a further restatement of our consolidated financial 
statements, cause us to fail to meet our reporting obligations, reduce our ability to obtain financing or cause 
investors to lose confidence in our reported financial information, leading to a decline in our stock price. We cannot 
assure you that we will not discover additional weaknesses in our internal control over financial reporting. 

As a result of the material weakness, our management concluded that we did not maintain effective internal 
control over financial reporting as of March 31, 2019. This could cause investors to lose confidence in the reliability 
of our financial statements and could result in a decrease in the value of our common stock. Failure to comply with 
the Sarbanes-Oxley Act of 2002 could potentially subject us to sanctions or investigations by the SEC, NYSE, or 
other regulatory authorities. 

Furthermore, as we grow our business, our disclosure controls and internal controls will become more 
complex, and we may require significantly more resources to ensure the effectiveness of these controls. If we are 
unable to continue upgrading our financial and management controls, reporting systems, information technology and 
procedures in a timely and effective fashion, additional management and other resources may need to be devoted to 
assist in compliance with the disclosure and financial reporting requirements and other rules that apply to reporting 
companies, which could adversely affect our business, financial position and results of operations. 

The Prior Restatement of our previously issued financial resulted in an investigation by the SEC as well as 
private litigation, and could result in additional litigation, government investigations and enforcement actions 
that could have a material adverse impact on our results of operations, financial condition, liquidity and cash 
flows. 

As further described below under “Item 3. Legal Proceedings,” the accounting errors and internal control 
problems disclosed in the Prior Restatement were the subject of a putative class action lawsuit filed in the U.S. 
District Court for the Southern District of New York. While the United States Court of Appeals for the Second 
Circuit denied a petition for rehearing on an order affirming dismissal of the class action on November 28, 2017, on 
November 27, 2018, the plaintiff filed a motion for relief from final judgment and for leave to file an amended 
complaint with the district court, on which the district court has not yet ruled. We were also subject of a formal 
investigation by the SEC’s Division of Enforcement (the “Enforcement Division”), resulting in a $1.0 million fine as 
part of the settlement of that investigation. We could become subject to additional litigation or government 
investigations and enforcement actions arising out of the Prior Restatement, the Stock-Based Compensation 
Restatement, as well as any delinquent Exchange Act filings. 

20

Our management devoted significant time and attention related to these matters, and we may be required to 
devote even more time and attention to such matters in the future, and these and any additional matters that arise 
could have a material adverse impact on our results of operations, financial condition, liquidity and cash flows. Any 
insurance that we maintain may not be adequate for such matters in the future and there is risk that our insurers 
could rescind or otherwise not renew the policies, that some or all of any future claims will not be covered by such 
policies, or that, even if covered, our ultimate liability will exceed the available insurance. For additional discussion 
of these matters, see “Note 15. Commitments and Contingencies — Litigation” to our audited consolidated financial 
statements included in “Item 8. Financial Statements and Supplementary Data” of this Form 10-K. 

Our operations are affected by various laws and regulations in the markets in which we operate, and our failure 
to obtain or maintain approvals by municipalities, state departments of transportation, engineers and developers 
may affect our results of operations. 

Our operations are principally affected by various statutes, regulations and laws in the United States, Canada 
and Latin America. While we are not engaged in a regulated industry, we are subject to various laws applicable to 
businesses generally, including laws affecting land usage, zoning, the environment, health and safety, transportation, 
labor and employment practices (including pensions), competition, immigration and other matters. Additionally, 
approvals by municipalities, the U.S. and state departments of transportation, engineers and developers may affect 
the products our customers are allowed to use, and, consequently, failure to obtain or maintain such approvals may 
affect the saleability of our products. Building codes may also affect the products our customers are allowed to use, 
and, consequently, changes in building codes may also affect the saleability of our products. Changes in applicable 
regulations governing the sale of some of our products could increase our costs of doing business. In addition, 
changes to applicable tax laws and regulations could increase our costs of doing business. We cannot provide 
assurance that we will not incur material costs or liabilities in connection with regulatory requirements. 

In addition, the U.S. Tax Cuts and Jobs Act of 2017 (the “Tax Cuts and Jobs Act”) significantly changed how 

the U.S. taxes corporations. The Tax Cuts and Jobs Act requires complex computations to be performed that were 
not previously required in U.S. tax law, significant judgments to be made in interpretation of the provisions of the 
Tax Cuts and Jobs Act and significant estimates in calculations, and the preparation and analysis of information not 
previously relevant or regularly produced. The U.S. Treasury Department, the Internal Revenue Service (the “IRS”), 
and other standard-setting bodies could interpret or issue guidance on how provisions of the Tax Cuts and Jobs Act 
will be applied or otherwise administered that is different from our interpretation. 

We deliver products to many of our customers through our own fleet of vehicles. The U.S. DOT regulates our 

operations in domestic interstate commerce. We are subject to safety requirements governing interstate operations 
prescribed by the U.S. DOT. Vehicle dimensions and driver hours of service also remain subject to both federal and 
state regulation. More restrictive limitations on vehicle weight and size, trailer length and configuration, or driver 
hours of service could increase our costs, which, if we are unable to pass these cost increases on to our customers, 
would reduce our gross profit and net income (loss) and increase our selling, general and administrative expenses. 

We cannot predict whether future developments in law and regulations concerning our business units will 

affect our business, financial condition and results of operations in a negative manner. Similarly, we cannot assess 
whether our business units will be successful in meeting future demands of regulatory agencies in a manner which 
will not materially adversely affect our business, financial condition, results of operations and cash flows. 

Interruptions in the proper functioning of information technology systems could disrupt operations and cause 
unanticipated increases in costs, decreases in revenues, or both. The implementation of our technology initiatives 
could disrupt our operations in the near term, and our technology initiatives might not provide the anticipated 
benefits or might fail. 

Because we use our information technology (“IT”) systems to, among other things, manage inventories and 

accounts receivable, make purchasing decisions and monitor our results of operations, the proper functioning of our 
IT systems is important to the successful operation of our business. Although our IT systems are protected through 
physical and software safeguards and remote processing capabilities exist, IT systems are still vulnerable to natural 
disasters, power losses, unauthorized access, telecommunication failures and other problems. If critical IT systems 
fail, or are otherwise unavailable, our ability to process orders, track credit risk, identify business opportunities, 

21 

 
 
Table of Contents 

Advanced Drainage Systems, Inc. 

maintain proper levels of inventories, collect accounts receivable and pay expenses and otherwise manage our 
business units would be adversely affected. 

Management uses IT systems to support decision making and to monitor business performance. We may fail 

to generate accurate financial and operational reports essential for making decisions at various levels of 
management. Failure to adopt systematic procedures to maintain quality IT general controls could disrupt our 
business. In addition, if we do not maintain adequate controls such as reconciliations, segregation of duties and 
verification to prevent errors or incomplete information, our ability to operate our business could be limited. 

Third-party service providers are responsible for managing a significant portion of our IT systems. Our 

business and results of operations may be adversely affected if the third-party service provider does not perform 
satisfactorily. Additionally, there is no guarantee that we will continue to have access to these third-party IT systems 
after our current license agreements expire, and, if we do not obtain licenses to use effective replacement IT 
systems, our financial condition and operating results could be adversely affected. 

We have made, and will continue to make, significant technology investments in each of our business units 

and in our administrative functions. Our technology initiatives are designed to streamline our operations to allow our 
associates to continue to provide high quality service to our customers and to provide our customers a better 
experience, while improving the quality of our internal control environment. The cost and potential problems and 
interruptions associated with the implementation of our technology initiatives could disrupt or reduce the efficiency 
of our operations in the near term. In addition, our new or upgraded technology might not provide the anticipated 
benefits, it might take longer than expected to realize the anticipated benefits or the technology might fail altogether. 
The occurrence of such interruptions could have a material adverse effect on our business financial condition and 
results of operations. 

Cybersecurity attacks may threaten our confidential information, disrupt operations and result in harm to our 
reputation and adversely impact our business and financial performance. 

Cybersecurity attacks across industries, including ours, are increasing in sophistication and frequency and may 

range from uncoordinated individual attempts to measures targeted specifically at us. These attacks include but are 
not limited to, malicious software or viruses, attempts to gain unauthorized access to, or otherwise disrupt, our 
information systems, attempts to gain unauthorized access to business, proprietary or other confidential information, 
and other electronic security breaches that could lead to disruptions in critical systems, unauthorized release of 
confidential or otherwise protected information and corruption of data. Cybersecurity failures may be caused by 
employee error, malfeasance, other corporate or governmental actors, system errors or vulnerabilities, including 
vulnerabilities of our vendors, suppliers, and their products. While we have been subject to cybersecurity attacks in 
the past, that (based on information known to date) did not have a material impact on our financial condition or 
results of operations, we may experience such attacks in the future, potentially with more frequency or 
sophistication which may have a material impact on our financial condition or results of operations. 

Failures of our IT systems as a result of cybersecurity attacks or other disruptions could result in a breach of 

critical operational or financial controls and lead to a disruption of our operations, commercial activities or financial 
processes. Cybersecurity attacks or other disruptions impacting significant customers and/or suppliers could also 
lead to a disruption of our operations or commercial activities. Despite our attempts to safeguard our systems and 
mitigate potential risks, there is no assurance that such actions will be sufficient to prevent cyberattacks or security 
breaches that manipulate or improperly use our systems or networks, compromise confidential or otherwise 
protected information, destroy or corrupt data, or otherwise disrupt our operations. The occurrence of such events 
could have a material adverse effect on our business financial condition and results of operations. 

If we become subject to material liabilities under our self-insured programs, our financial results may be 
adversely affected. We may see increased costs arising from health care legislation. 

We provide workers’ compensation, automobile and product/general liability coverage through a high 
deductible insurance program. In addition, we provide medical coverage to some of our employees through a self-
insured preferred provider organization. Possible changes to health care legislation could have possible adverse 
effects including increased costs, exposure to expanded liability and requirements for us to revise ways in which we 

22 

 
 
Table of Contents 

Advanced Drainage Systems, Inc. 

provide healthcare and other benefits to our employees. Our business, financial condition, results of operations and 
cash flows may be adversely affected if the cost, number and severity of insurance claims increases. 

Our success depends upon our ability to control labor costs and to attract, train and retain highly qualified 
employees and key personnel. 

To be successful, we must attract, train and retain a large number of highly qualified employees while 
controlling related labor costs. Our ability to control labor costs is subject to numerous external factors, including 
prevailing wage rates and health and other insurance costs. We compete with other businesses for these employees 
and invest significant resources in training and motivating them. There is no assurance that we will be able to attract 
or retain highly qualified employees in the future, including, in particular, those employed by companies we acquire. 
None of our domestic employees are currently covered by collective bargaining or other similar labor agreements. 
However, if a number of our employees were to unionize, including in the wake of any future legislation that makes 
it easier for employees to unionize, the effect on us may be negative. Inability to negotiate acceptable new contracts 
under any collective bargaining arrangements could cause strikes or other work stoppages, and new contracts could 
result in increased operating costs. If any such strikes or other work stoppages occur, or if employees become 
represented by a union, we could experience a disruption of our operations and higher labor costs. Labor relations 
matters affecting our suppliers of products and services could also adversely affect our business from time to time. 

In addition, our business results of operations depend largely upon our chief executive officer and senior 

management team as well as our plant managers and sales personnel, including those of companies recently 
acquired, and their experience, knowledge of local market dynamics and specifications and long-standing customer 
relationships. We customarily sign executive responsibility agreements with certain key personnel who are granted 
restricted stock or stock options under our employee incentive compensation programs, which contain 
confidentiality and non-competition provisions. However, in certain jurisdictions, non-competition provisions may 
not be enforceable or may not be enforceable to their full extent. Our inability to retain or hire qualified plant 
managers or sales personnel at economically reasonable compensation levels would restrict our ability to grow our 
business, limit our ability to continue to successfully operate our business and result in lower operating results and 
profitability. 

If we are unable to protect our intellectual property rights, or we infringe on the intellectual property rights of 
others, our ability to compete could be negatively impacted. 

Our ability to compete effectively depends, in part, upon our ability to protect and preserve proprietary aspects 

of our intellectual property, which we attempt to do, both in the United States and in foreign countries, through a 
combination of patent, trademark, copyright and trade secret laws, as well as licensing agreements and third-party 
nondisclosure and assignment agreements. Because of the differences in foreign trademark, patent and other laws 
concerning proprietary rights, our intellectual property rights may not receive the same degree of protection in 
foreign countries as they would in the United States. Our failure to obtain or maintain adequate protection of our 
intellectual property rights for any reason could have a material adverse effect on our business, results of operations 
and financial condition. 

We have applied for patent protection relating to certain existing and proposed products, processes and 
services. While we generally apply for patents in those countries where we primarily intend to make, have made, 
use, or sell patented products, we may not accurately predict all of the countries where patent protection will 
ultimately be desirable. If we fail to timely file a patent application in any such country, we may be precluded from 
doing so at a later date. Furthermore, we cannot assure that any of our patent applications will be approved. We also 
cannot assure that the patents issuing as a result of our foreign patent applications will have the same scope of 
coverage as our United States patents. The patents we own could be challenged, invalidated or circumvented by 
others and may not be of sufficient scope or strength to provide us with any meaningful protection or commercial 
advantage. Further, we cannot assure that competitors will not infringe our patents, or that we will have adequate 
resources to enforce our patents. 

We also rely on unpatented proprietary technology. It is possible that others will independently develop the 

same or similar technology or otherwise obtain access to our unpatented technology. To protect our trade secrets and 
other proprietary information, we generally require applicable employees, consultants, advisors and collaborators to 

23 

 
 
Table of Contents 

Advanced Drainage Systems, Inc. 

enter into confidentiality agreements. We cannot assure that these agreements will provide meaningful protection for 
our trade secrets, know-how or other proprietary information in the event of any unauthorized use, misappropriation 
or disclosure of such trade secrets, know-how or other proprietary information. If we are unable to maintain the 
proprietary nature of our technologies, we could be materially adversely affected. 

We rely on our trademarks, trade names and brand names to distinguish our products from the products of our 

competitors and have registered or applied to register many of these trademarks. We cannot assure that our 
trademark applications will be approved. Third parties may also oppose our trademark applications or otherwise 
challenge our use of the trademarks. In the event that our trademarks are successfully challenged, we could be 
forced to rebrand our products, which could result in loss of brand recognition, and could require us to devote 
resources to advertising and marketing new brands. Further, we cannot assure that competitors will not infringe our 
trademarks or that we will have adequate resources to enforce our trademarks. We also license third parties to use 
certain of our trademarks. In an effort to preserve our trademark rights, we enter into license agreements with these 
third parties which govern the use of our trademarks and which require our licensees to abide by quality control 
standards with respect to the goods and services that they provide under our trademarks. Although we make efforts 
to police the use of our trademarks by our licensees, we cannot assure that these efforts will be sufficient to ensure 
that our licensees abide by the terms of their licenses. In the event that our licensees fail to do so, our trademark 
rights could be diluted. 

Although we rely on copyright laws to protect the works of authorship (including software) created by us, we 
generally do not register the copyrights in any of our copyrightable works. Copyrights of United States origin must 
be registered before the copyright owner may bring an infringement suit in the United States. Furthermore, if a 
copyright of United States origin is not registered within three months of publication of the underlying work, the 
copyright owner is precluded from seeking statutory damages or attorneys’ fees in any United States enforcement 
action and is limited to seeking actual damages and lost profits. Accordingly, if one of our unregistered copyrights 
of United States origin is infringed by a third party, we will need to register the copyright before we can file an 
infringement suit in the United States, and our remedies in any such infringement suit may be limited. 

The misuse of our intellectual property rights by others could adversely impact our ability to compete, cause 

our net sales to decrease or otherwise harm our business. If it became necessary for us to resort to litigation to 
protect our intellectual property rights, any proceedings could be burdensome and costly, and we may not prevail. 

Also, we cannot be certain that the products that we sell do not and will not infringe issued patents or other 

intellectual property rights of others. Further, we are subject to legal proceedings and claims in the ordinary course 
of our business, including claims of alleged infringement of the patents, trademarks and other intellectual property 
rights of third parties by us or our customers, whom we generally indemnify in connection with their use of the 
products that we manufacture. These claims could divert management’s attention and resources and may require us 
to initiate or defend protracted and costly litigation on behalf of ourselves or our customers, regardless of the merits 
of the claims. Should we be found liable for infringement, we may be required to enter into licensing agreements (if 
available on acceptable terms or at all) or pay damages and cease making or selling certain products. Moreover, we 
may need to redesign or sell different products to avoid future infringement liability. Any of the foregoing could 
cause us to incur significant costs, prevent us from selling our products or negatively impact our ability to compete. 

We could incur significant costs in complying with environmental, health and safety laws or permits or as a 
result of satisfying any liability or obligation imposed under such laws or permits. 

Our operations are subject to various federal, state, local and foreign environmental, health and safety laws 

and regulations. Among other things, these laws regulate the emission or discharge of materials into the 
environment, govern the use, storage, treatment, disposal and management of hazardous substances and wastes, 
protect the health and safety of our employees and the end users of our products, regulate the materials used in and 
the recycling of products and impose liability for the costs of investigating and remediating, and damages resulting 
from, present and past releases of hazardous substances. Violations of these laws and regulations, failure to obtain or 
maintain required environmental permits or non-compliance with any conditions contained in any environmental 
permit can result in substantial fines or penalties, injunctive relief, requirements to install pollution or other controls 
or equipment, civil and criminal sanctions, permit revocations and/or facility shutdowns. We could be held liable for 
the costs to address contamination of any real property we have ever owned, leased, operated or used, including as a 

24 

 
 
Table of Contents 

Advanced Drainage Systems, Inc. 

disposal site. We could also incur fines, penalties, sanctions or be subject to third-party claims for property damage, 
personal injury or nuisance or otherwise as a result of violations of or liabilities under environmental laws in 
connection with releases of hazardous or other materials. 

In addition, changes in, or new interpretations of, existing laws, regulations or enforcement policies, the 
discovery of previously unknown contamination, or the imposition of other environmental liabilities or obligations 
in the future, including additional investigation or other obligations with respect to any potential health hazards of 
our products or business activities or the imposition of new permit requirements, may lead to additional compliance 
or other costs that could have material adverse effect on our business, financial condition, results of operations and 
cash flows. 

A change in our product mix could adversely affect our results of operations. 

Our results may be affected by a change in our product mix on which our gross margin depends. Changes in 

our product mix may result from marketing activities to existing customers and needs communicated to us from 
existing and prospective customers. Our outlook, budgeting and strategic planning assume a certain product mix of 
sales. If actual results vary from this projected product mix of sales, our financial results could be negatively 
impacted. 

We may be affected by global climate change or by legal, regulatory or market responses to such potential 
change. 

Concern over climate change, including the impact of global warming, has led to significant federal, state, and 
international legislative and regulatory efforts to limit greenhouse gas (“GHG”) emissions. For example, in the past 
several years, the U.S. Congress has considered various bills that would regulate GHG emissions. While these bills 
have not yet received sufficient Congressional support for enactment, some form of federal climate change 
legislation is possible in the future. Even in the absence of such legislation, the Environmental Protection Agency, 
spurred by judicial interpretation of the Clean Air Act, may regulate GHG emissions, especially diesel engine 
emissions, and this could impose substantial costs on us. These costs include an increase in the cost of the fuel and 
other energy we purchase and capital costs associated with updating or replacing our internal fleet of trucks and 
other vehicles prematurely. In addition, new laws or future regulation could directly and indirectly affect our 
customers and suppliers (through an increase in the cost of production or their ability to produce satisfactory 
products) and our business (through the impact on our inventory availability, cost of sales, operations or demands 
for the products we sell). Until the timing, scope and extent of any future regulation becomes known, we cannot 
predict its effect on our cost structure or our operating results. Notwithstanding our dedication to being a responsible 
corporate citizen, it is reasonably possible that such legislation or regulation could impose material costs on us. 

Anti-terrorism measures and other disruptions to the raw material supply network could impact our operations. 

Our ability to provide efficient distribution of products to our customers is an integral component of our 
overall business strategy. In the aftermath of terrorist attacks in the United States, federal, state and local authorities 
have implemented and continue to implement various security measures that affect the raw material supply network 
in the United States and abroad. If security measures disrupt or impede the receipt of sufficient raw materials, we 
may fail to meet the needs of our customers or may incur increased expenses to do so. 

Risks Relating to Our Indebtedness 

We have substantial debt and may incur substantial additional debt, which could adversely affect our financial 
health, reduce our profitability, limit our ability to obtain financing in the future and pursue certain business 
opportunities and reduce the value of your investment. 

As of March 31, 2019, we had an aggregate principal amount of $236.8 million of outstanding debt. In fiscal 

2019, we incurred $10.8 million of interest expense, net of the impact of interest rate swaps, related to this debt. 

The amount of our debt or such other obligations could have important consequences for holders of our 

common stock, including, but not limited to: a substantial portion of our cash flow from operations must be 
dedicated to the payment of principal and interest on our indebtedness, thereby reducing the funds available to us for 
other purposes; our ability to obtain additional financing for working capital, capital expenditures, acquisitions, debt 

25 

 
 
Table of Contents 

Advanced Drainage Systems, Inc. 

service requirements or general corporate purposes and other purposes may be impaired in the future; we are 
exposed to the risk of increased interest rates because a portion of our borrowings is at variable rates of interest; we 
may be at a competitive disadvantage compared to our competitors with less debt or with comparable debt at more 
favorable interest rates and that, as a result, may be better positioned to withstand economic downturns; our ability 
to refinance indebtedness may be limited or the associated costs may increase; our ability to engage in acquisitions 
without raising additional equity or obtaining additional debt financing may be impaired in the future; it may be 
more difficult for us to satisfy our obligations to our creditors, resulting in possible defaults on and acceleration of 
such indebtedness; we may be more vulnerable to general adverse economic and industry conditions; and our 
flexibility to adjust to changing market conditions and our ability to withstand competitive pressures could be 
limited, or we may be prevented from making capital investments that are necessary or important to our operations 
in general, growth strategy and efforts to improve operating margins of our business units. 

If our cash flow and capital resources are insufficient to fund our debt service obligations, we may be forced to 

reduce or delay capital expenditures, sell assets, seek to obtain additional equity capital or refinance our debt. We 
cannot make assurances that we will be able to refinance our debt on terms acceptable to us, or at all. In the future, our 
cash flow and capital resources may not be sufficient for payments of interest on and principal of our debt, and such 
alternative measures may not be successful and may not permit us to meet our scheduled debt service obligations. 

We cannot make assurances that we will be able to refinance any of our indebtedness, or obtain additional 

financing, particularly because of our high levels of debt and the debt incurrence restrictions imposed by the 
agreements governing our debt, as well as prevailing market conditions. We could face substantial liquidity 
problems and might be required to dispose of material assets or operations to meet our debt service and other 
obligations. Subject to certain exceptions, our Secured Bank Loan and our Senior Notes, which we have defined in 
“Note 13. Debt” to our consolidated financial statements included in “Item 8. Financial Statements and 
Supplementary Data,” restrict our ability to dispose of assets and how we use the proceeds from any such 
dispositions. We cannot make assurances that we will be able to consummate those dispositions, or if we do, what 
the timing of the dispositions will be or whether the proceeds that we realize will be adequate to meet our debt 
service obligations, when due. 

Despite our current level of indebtedness, we may still be able to incur substantially more debt. This could further 
exacerbate the risks to our financial condition described above. 

We may be able to incur significant additional indebtedness in the future. Although the agreements governing 
our indebtedness contain restrictions on the incurrence of additional indebtedness, these restrictions are subject to a 
number of qualifications and exceptions, and the additional indebtedness incurred in compliance with these 
restrictions could be substantial. These restrictions also will not prevent us from incurring obligations that do not 
constitute indebtedness, including obligations under lease arrangements that are currently recorded as operating 
leases. In addition, our Secured Bank Loan provides an aggregate commitment of up to $550.0 million. As of 
March 31, 2019, we had an additional $407.1 million of availability under the Secured Bank Loan. If new debt is 
added to our current debt levels, the related risks that we now face could intensify. See “Note 13. Debt” to our 
consolidated financial statements included in “Item 8. Financial Statements and Supplementary Data.” 

The agreements and instruments governing our debt contain restrictions and limitations that could significantly 
impact our ability to operate our business and adversely affect the holders of our common stock. 

The covenants contained in our Secured Bank Loan and our Senior Notes, which we refer to collectively as 
our Credit Facilities, are consistent. These covenants, among other things, restrict or limit our ability to: dispose of 
assets; incur additional indebtedness (including guarantees of additional indebtedness); prepay or amend our various 
debt instruments; pay dividends and make certain payments; redeem stock or make other distributions; create liens 
on assets; make certain investments; engage in certain asset sales, mergers, acquisitions, consolidations or sales of 
all, or substantially all, of our assets; and engage in certain transactions with affiliates. 

Our ability to comply with the covenants and restrictions contained in the Credit Facilities may be affected by 
economic, financial and industry conditions beyond our control. The breach of any of these covenants or restrictions 
could result in a default under the Credit Facilities that would permit the applicable lenders or noteholders, as the case 
may be, to declare all amounts outstanding thereunder to be due and payable, together with accrued and unpaid interest.

If we are unable to repay indebtedness, secured parties having secured obligations, such as the lenders or noteholders, 
as the case may be, under the Credit Facilities, could proceed against the collateral securing the secured obligations. 
This could have serious consequences to our financial condition and results of operations and could cause us to become 
bankrupt or insolvent. 

We may have future capital needs and may not be able to obtain additional financing on acceptable terms. 

Although we believe that our current cash position and the additional committed funding available under our 
Credit Facilities is sufficient for our current operations, any reductions in our available borrowing capacity, or our 
inability to renew or replace our debt facilities, when required or when business conditions warrant, could have a 
material adverse effect on our business, financial condition and results of operations. The economic conditions, 
credit market conditions, and economic climate affecting our industry, as well as other factors, may constrain our 
financing abilities. Our ability to secure additional financing, if available, and to satisfy our financial obligations 
under indebtedness outstanding from time to time will depend upon our future operating performance, the 
availability of credit generally, economic conditions and financial, business and other factors, many of which are 
beyond our control. The market conditions and the macroeconomic conditions that affect our industry could have a 
material adverse effect on our ability to secure financing on favorable terms, if at all. 

If financing is not available when needed, or is available on unfavorable terms, we may be unable to take 
advantage of business opportunities or respond to competitive pressures, any of which could have a material adverse 
effect on our business, financial condition and results of operations. 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, and any new securities we issue could have rights, 
preferences and privileges senior to those of holders of our common stock. 

We may not be able to satisfy our outstanding obligations upon a change of control. 

Under the Secured Bank Loan, a change of control (as defined therein) constitutes an event of default that 

permits the lenders to accelerate the maturity of borrowings under the agreement and terminate their commitments 
to lend. Additionally, under the Senior Notes, a change of control (as defined therein) constitutes an event of default 
that permits the noteholders to declare all of their notes to be immediately due and payable. In order to avoid events 
of default under each of our Credit Facilities, we may therefore have to avoid certain change of control transactions 
that would otherwise be beneficial to us. 

Risks Relating to Our Common Stock 

Our ability to make future dividend payments, if any, may be restricted. 

We have a history of paying dividends to our stockholders when sufficient cash is available, and we 
currently intend to pay dividends in the future. Any determination to pay dividends on our capital stock in the 
future will be at the discretion of our board of directors, subject to applicable laws and the provisions of our 
amended and restated certificate of incorporation (including those relating to the payment of dividends on our 
convertible preferred stock), and will depend on our financial condition, results of operations, capital 
requirements, general business conditions and other factors that our board of directors considers relevant. In 
addition, the terms of our Credit Facilities contain restrictions on our ability to pay dividends. Also, Delaware law 
may impose requirements that may restrict our ability to pay dividends to holders of our common stock. 

In addition, we recently declared a special dividend. The fact that we declared a special dividend does not 

suggest and stockholders should not expect that our Board of Directors will declare a regular or special cash 
dividend in the future. Any future dividends will depend on a variety of factors, including our liquidity and 
balance sheet position, solvency, strength of operations, product successes, research and development needs and 
other factors.

We cannot assure our stockholders that an active market for shares of our common stock can be sustained and 
the market price of our common stock may be volatile and could decline in the future. 

We cannot assure that an active public market for our common stock will be sustained. In the absence of a 

public trading market, you may not be able to liquidate your investment in our common stock. The market price of 
our common stock may fluctuate significantly. Among the factors that could affect our stock price are: industry or 
general market conditions; domestic and international economic factors unrelated to our performance; changes in 
our customers’ preferences; new regulatory pronouncements and changes in regulatory guidelines; actual or 
anticipated fluctuations in our quarterly operating results; changes in securities analysts’ estimates of our financial 
performance or lack of research and reports by industry analysts; action by institutional stockholders or other large 
stockholders, including future sales; speculation in the press or investment community; investor perception of us and 
our industry; changes in market valuations or earnings of similar companies; announcements by us or our 
competitors of significant products, contracts, acquisitions or strategic partnerships; developments or disputes 
concerning patents or proprietary rights, including increases or decreases in litigation expenses associated with 
intellectual property lawsuits we may initiate, or in which we may be named as defendants; failure to complete 
significant sales; any future sales of our common stock or other securities; and additions or departures of key 
personnel. 

The stock markets have experienced extreme volatility in recent years that has been unrelated to the operating 
performance of particular companies. These broad market fluctuations may adversely affect the trading price of our 
common stock. In the past, following periods of volatility in the market price of a company’s securities, class action 
litigation has often been instituted against such company. Any litigation of this type brought against us could result 
in substantial costs and a diversion of our management’s attention and resources, which would harm our business, 
operating results and financial condition. 

Future sales of shares by existing stockholders, including our Employee Stock Ownership Plan, could cause our 
stock price to decline. 

Sales of substantial amounts of our common stock in the public market, or the perception that these sales 

could occur, could cause the market price of our common stock to decline. Based on shares outstanding as of 
March 31, 2019, we have 57.8 million outstanding shares of common stock, including 0.3 million outstanding shares 
of our restricted stock, a significant portion of which are freely tradeable without restriction under the Securities Act 
of 1933, as amended, (“Securities Act”) unless held by “affiliates,” as that term is defined in Rule 144 under the 
Securities Act. The remaining shares of common stock outstanding are restricted securities within the meaning of 
Rule 144 under the Securities Act. Restricted securities may be sold in the public market only if their offer and sale 
is registered under the Securities Act or if the offer and sale of those securities qualify for an exemption from 
registration, including exemptions provided by Rules 144 and 701 under the Securities Act. We have filed one or 
more registration statements on Form S-8 under the Securities Act to register the shares of common stock to be 
issued under our equity compensation plans and, as a result, all shares of common stock acquired upon exercise of 
stock options granted under our plans are also freely tradable under the Securities Act, unless purchased by our 
affiliates. As of March 31, 2019, there were stock options outstanding to purchase a total of approximately 
1.7 million shares of our common stock. In addition, approximately 2.7 million shares of common stock are 
available for grant under our 2017 Omnibus Plan. 

Certain of our significant stockholders may distribute shares that they hold to their investors who themselves 

may then sell into the public market. Such sales may not be subject to the volume, manner of sale, holding period 
and other limitations of Rule 144 of the Securities Act (“Rule 144”). As resale restrictions end, the market price of 
our common stock could decline if the holders of those shares sell them or are perceived by the market as intending 
to sell them. 

28 

 
 
Table of Contents 

Advanced Drainage Systems, Inc. 

All of the shares of our convertible preferred stock held by our Employee Stock Ownership Plan (“ESOP”) 

may be converted into our common stock at any time by action of the ESOP trustee, and will be automatically 
converted into our common stock upon distributions of such shares allocated to the ESOP accounts of ESOP 
participants upon a distribution event such as retirement or other termination of employment. Such distributed 
common stock will not be subject to any lock-up agreement and will be eligible for future sale, subject to the 
applicable volume, manner of sale, holding period and other limitations of Rule 144. As of March 31, 2019, there 
were approximately 22.6 million shares of convertible preferred stock held by our ESOP, which in aggregate could 
be converted into approximately 17.4 million shares of our common stock. All of these shares will be eligible for 
future sale, either by the ESOP trustee or by ESOP participants, subject to the limitations of Rule 144. 

In the future, we may issue additional shares of common stock or other equity or debt securities convertible 
into common stock in connection with a financing, acquisition, litigation settlement or employee arrangement or 
otherwise. Any of these issuances could result in substantial dilution to our existing stockholders and could cause 
the trading price of our common stock to decline. 

Our directors, officers and principal stockholders have significant voting power and may take actions that may 
not be in the best interests of our other stockholders. 

As of May 21, 2019, our directors, officers and principal stockholders and their affiliates collectively own 

approximately 49.0% of our outstanding shares of common stock. Additionally, our ESOP holds convertible 
preferred stock that converts into a substantial number of shares of our common stock and, prior to conversion, is 
entitled to vote on a one-for-one basis on any matter requiring the vote or consent of our stockholders, voting 
together with our common stock as a single class unless otherwise required by law. Thus, the collective voting 
power of our directors, officers and principal stockholders and their affiliates as of May 21, 2019 is approximately 
60.8%, inclusive of the outstanding shares of convertible preferred stock held by the ESOP. As a result, these 
stockholders, if they act together, may be able to control our management and affairs and most matters requiring 
stockholder approval, including the election of directors and approval of significant corporate transactions. This 
concentration of ownership may have the effect of delaying or preventing a change of control and might adversely 
affect the market price of our common stock. This concentration of ownership may not be in the best interests of our 
other stockholders. 

The trustee of our ESOP has certain limited powers to vote a large block of shares on matters presented to 
stockholders for approval. 

In general, the ESOP trustee votes the shares of convertible preferred stock held by the ESOP as directed by 

the ESOP’s participants. Consequently, the ESOP trustee has the ability to vote a significant block of shares on 
certain matters presented to stockholders for approval. Each participant in the ESOP may direct the ESOP trustee on 
how to vote the shares of convertible preferred stock allocated to the participant’s ESOP accounts; and the ESOP 
trustee must vote any unallocated stock and allocated stock for which no participant instructions were received in the 
same proportion as the allocated stock for which participants’ voting instructions have been received is voted. 

Anti-takeover provisions in our charter documents and Delaware law could discourage, delay or prevent a 
change in control of us and may affect the trading price of our common stock. 

Our amended and restated certificate of incorporation and amended and restated bylaws include a number of 
provisions that may discourage, delay or prevent a change in our management or control over us that stockholders 
may consider favorable. For example, our amended and restated certificate of incorporation and amended and 
restated bylaws: authorize the issuance of “blank check” preferred stock that could be issued by our board of 
directors to thwart a takeover attempt; maintain a classified board of directors, as a result of which our board will 
continue to be divided into three classes, with each class serving for staggered three-year terms, which prevents 
stockholders from electing an entirely new board of directors at an annual meeting; limit the ability of stockholders 
to remove directors; provide that vacancies on our board of directors, including newly-created directorships, may be 
filled only by a majority vote of directors then in office; prohibit stockholders from calling special meetings of 
stockholders; prohibit stockholder action by written consent, thereby requiring all actions to be taken at a meeting of 
the stockholders; do not give the holders of our common stock cumulative voting rights with respect to the election 
of directors, which means that the holders of a majority of our outstanding shares of common stock can elect all 
directors standing for election; establish advance notice requirements for nominations for election to our board of 

29 

 
 
Table of Contents 

Advanced Drainage Systems, Inc. 

directors or for proposing matters that can be acted upon by stockholders at stockholder meetings; require a super-
majority stockholders vote of 75% to approve any reorganization, recapitalization, share exchange, share 
reclassification, consolidation, merger, conversion or sale of all or substantially all assets to which we are a party 
that is not approved by the affirmative vote of at least 75% of the members of our board of directors; and require the 
approval of holders of at least 75% of the outstanding shares of our voting common stock to amend the bylaws and 
certain provisions of the certificate of incorporation. 

Any provision of our amended and restated certificate of incorporation, amended and restated bylaws or 

Delaware General Corporation Law that has the effect of delaying or deterring a change in control could limit the 
opportunity for our stockholders to receive a premium for their shares of our common stock, and could also affect 
the price that some investors are willing to pay for our common stock. 

Our amended and restated certificate of incorporation and amended and restated bylaws may also make it 

difficult for stockholders to replace or remove our management. These provisions may facilitate management 
entrenchment that may delay, deter, render more difficult or prevent a change in our control, which may not be in 
the best interests of our stockholders. 

Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of 
Delaware is the exclusive forum for substantially all disputes between us and our stockholders, which could limit 
our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, 
employees or agents. 

Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of 
Delaware is the exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting 
a claim of breach of a fiduciary duty owed to us or our stockholders by our directors, officers, employees or agents; 
any action asserting a claim against us arising under the Delaware General Corporation Law, our amended and 
restated certificate of incorporation or our amended and restated bylaws; or any action asserting a claim against us 
that is governed by the internal affairs doctrine. Any person or entity purchasing or otherwise acquiring any interest 
in shares of our common stock shall be deemed to have notice of and to have consented to the provisions of our 
amended and restated certificate of incorporation described above. The choice of forum provision may limit a 
stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, 
officers, employees or agents, which may discourage such lawsuits against us or our directors, officers, employees 
or agents. If a court were to find the choice of forum provision contained in our amended and restated certificate of 
incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with 
resolving such action in other jurisdictions, which could adversely affect our business and financial condition.

(3)  The other facility is located in the Netherlands. 

We currently own approximately 36,000 square feet and lease approximately 16,000 square feet of office 

space in Hilliard, Ohio for our corporate headquarters.  

Our network of 56 manufacturing plants consist of 44 that are owned and 12 that are leased. We generally 

prefer to own our manufacturing plant locations, with a typical pipe manufacturing facility consisting of 
approximately 40,000 square feet and 15-20 acres of land for storage of pipe and related products. Our network of 
32 distribution centers consisted of 2 owned and 30 leased. We believe that our properties have been adequately 
maintained and are generally in good condition. The extent to which we use our properties varies by property and 
from time to time but we believe the capacity of our facilities is adequate for the level of production and distribution 
activities necessary in our business as presently conducted. Each distribution center carries single wall and dual wall 
pipe and fittings and Allied Products per needs of the local market. 

In-House Fleet 

As of March 31, 2019, our in-house fleet consist of approximately 700 tractors and approximately 1,250 

trailers that are specially designed to haul our lightweight pipe and fittings products. 

Item 3. 

Legal Proceedings 

As previously disclosed in the Company’s fiscal 2018 Form 10-K, the Company’s historical accounting 
practices were the subject of an investigation by SEC’s Division of Enforcement (the “Enforcement Division”), 
which began in August 2015. That matter was resolved on July 10, 2018 via a settlement between the Company and 
the SEC. Pursuant to the settlement, the Company consented to the entry of an administrative order without 
admitting or denying the findings therein. The order required the Company to cease and desist from committing or 
causing any violations and any future violations of certain provisions of the federal securities laws and the rules 
promulgated thereunder and to pay a civil monetary penalty of $1.0 million, which payment has been made. The 
Company previously accrued an expense for the penalty amount during fiscal 2018. 

On July 29, 2015, a putative stockholder class action, Christopher Wyche, individually and on behalf of all 

others similarly situated v. Advanced Drainage Systems, Inc., et al. (Case No. 1:15-cv-05955-KPF), was 
commenced in the U.S. District Court for the Southern District of New York (the “District Court”), naming the 
Company, along with Joseph A. Chlapaty, the Company’s former Chief Executive Officer, and Mark B. Sturgeon, 
the Company’s former Chief Financial Officer, as defendants and alleging violations of the federal securities laws. 
An amended complaint was filed on April 28, 2016. The amended complaint alleged that the Company made 
material misrepresentations and/or omissions of material fact in its public disclosures during the period from July 
25, 2014 through March 29, 2016, in violation of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, 
as amended, and Rule 10b-5 promulgated thereunder. On March 10, 2017, the District Court dismissed the 
plaintiff’s claims against all defendants in their entirety and with prejudice. The plaintiff appealed to the United 
States Court of Appeals for the Second Circuit, and on October 13, 2017 the District Court’s judgment was affirmed 
by the Second Circuit. On October 27, 2017, the plaintiff filed a petition for rehearing with the Second Circuit. The 
Second Circuit denied the petition for rehearing on November 28, 2017. On November 27, 2018, the plaintiff filed a 
motion for relief from final judgment and for leave to file an amended complaint with the District Court. The 
defendants have opposed the plaintiff’s motion and are awaiting a decision by the District Court. While it is 
reasonably possible that this matter ultimately could be decided unfavorably to the Company, the Company is 
currently unable to estimate the range of the possible losses, but it could be material. 

The Company is involved from time to time in various legal proceedings that arise in the ordinary course of 

our business, including but not limited to commercial disputes, environmental matters, employee related claims, 
intellectual property disputes and litigation in connection with transactions including acquisitions and divestitures. 
The Company does not believe that such litigation, claims, and administrative proceedings will have a material 

31

adverse impact on our financial position or our results of operations. The Company records a liability when a loss is 
considered probable, and the amount can be reasonably estimated.

Market Information for Common Stock 

Our common stock is listed and traded on the NYSE under the symbol “WMS”. 

During each quarter of fiscal 2018 and fiscal 2017, the Board of Directors approved a quarterly cash dividend 
of $0.07 per share and $0.06 per share, respectively, to all common stockholders. In addition, during each quarter of 
fiscal 2019, the Board of Directors approved a quarterly cash dividend of $0.08 per share to all common 
stockholders. Any future determination relating to dividends will be made at the discretion of our Board of Directors 
and will depend on a number of factors, including our future earnings, capital requirements, financial condition, 
future prospects, contractual restrictions, legal requirements and other factors our Board of Directors may deem 
relevant. 

During the first quarter of fiscal 2020, the Company declared a quarterly cash dividend of $0.09 per share of 
common stock. The dividend is payable on June 14, 2019 to stockholders of record at the close of business on June 
3, 2019. During the first quarter of fiscal 2020, the Board of Directors approved a special dividend of $1.00 per 
share payable on June 14, 2019 to stockholder of record at the close of business on June 3, 2019. 

Holders of Record 

As of May 21, 2019, we had 344 holders of record of our common stock. The number of holders of record is 
based upon the actual number of holders registered as of such date and does not include holders of shares in “street 
name” or persons, partnerships, associates, corporations or other entities in security position listings maintained by 
depositories.

The following graph presents a comparison from July 25, 2014 (the date our common stock commenced 
trading on the NYSE) through March 31, 2019 of the cumulative return of our common stock, the Standard and 
Poor’s Index (“S&P 500”) and the Russell 2000 Index (“Russell 2000”). The graph assumes investment of $100 on 
July 25, 2014 in our common stock and in each of the two indices and the reinvestment of dividends. 

Recent Sales of Unregistered Securities 

Since the completion of our IPO, we have not sold any securities without registration under the Securities Act 

of 1933, as amended. 

Issuer Purchases of Equity Securities 

In February 2017, our Board of Directors authorized the repurchase of up to $50 million of our common stock. 

Repurchases of common stock will be made in accordance with applicable securities laws. The stock repurchase 
program does not obligate us to acquire any particular amount of common stock, and may be suspended or 
terminated at any time at our discretion. During fiscal 2018, we repurchased 400,000 shares of common stock at a 
cost of $7.9 million.

to the acquisition of the noncontrolling interest in third quarter of fiscal 2019, the Redeemable noncontrolling 
interest in subsidiaries related to the noncontrolling interest in the BaySaver joint venture. See “Note 4. 
Acquisitions” and “Note 10. Investment in Consolidated Affiliates,” within our consolidated financial

Non-GAAP Measures 

EBITDA and Adjusted EBITDA – EBITDA and Adjusted EBITDA, non-GAAP financial measures, have been 

presented in this Annual Report on Form 10-K as supplemental measures of financial performance that are not 
required by, or presented in accordance with GAAP. We calculate EBITDA as net income before interest, income 
taxes and depreciation and amortization. We calculate adjusted EBITDA as net income before interest, income 
taxes, depreciation and amortization, stock-based compensation expense, non-cash charges and certain other 
expenses. 

EBITDA and Adjusted EBITDA are included in this Annual Report on Form 10-K because they are key 
metrics used by management and our Board of Directors to assess our financial performance. EBITDA and Adjusted 
EBITDA are frequently used by analysts, investors and other interested parties to evaluate companies in our 
industry. In addition to covenant compliance and executive performance evaluations, we use EBITDA and adjusted 
EBITDA to supplement GAAP measures of performance to evaluate the effectiveness of our business strategies, to 
make budgeting decisions and to compare our performance against that of other peer companies using similar 
measures. 

EBITDA and Adjusted EBITDA are not GAAP measures of our financial performance and should not be 
considered as alternatives to net income as measures of financial performance or cash flows from operations or any 
other performance measure derived in accordance with GAAP, and it should not be construed as an inference that 
our future results will be unaffected by unusual or non-recurring items. EBITDA and Adjusted EBITDA contain 
certain other limitations, including the failure to reflect our cash expenditures, cash requirements for working capital 
needs and cash costs to replace assets being depreciated and amortized. In evaluating EBITDA and adjusted

EBITDA, you should be aware that in the future we will incur expenses that are the same as or similar to some of 
the adjustments in this presentation, such as stock-based compensation expense, derivative fair value adjustments, 
and foreign currency transaction losses. Management compensates for these limitations by relying on our GAAP 
results in addition to using EBITDA and adjusted EBITDA supplementally. Our measure of EBITDA and adjusted 
EBITDA are not necessarily comparable to other similarly titled captions of other companies due to different 
methods of calculation.

Free Cash Flow - Free Cash Flow is a non-GAAP financial measure that comprises cash flow from operations 
less capital expenditures. Free Cash Flow is a measure used by management and the Company’s Board of Directors 
to assess the Company’s ability to generate cash. Accordingly, Free Cash Flow has been presented in this Annual 
Report on Form 10-K as a supplemental measure of liquidity that is not required by, or presented in accordance with 
GAAP, because management believes that Free Cash Flow provides useful information to investors and others in 
understanding and evaluating our ability to generate cash flow from operations after capital expenditures. 

Free Cash Flow is not a GAAP measure of our liquidity and should not be considered as an alternative to cash 

flow from operating activities as a measure of liquidity or any other liquidity measure derived in accordance with 
GAAP. Our measure of Free Cash Flow is not necessarily comparable to other similarly titled captions of other 
companies due to different methods of calculation.

Item 7. 

Management’s Discussion and Analysis of Financial Condition and Results of Operations 

Our fiscal year begins on April 1 and ends on March 31. Unless otherwise noted, references to “year” pertain 

to our fiscal year. For example, 2019 refers to fiscal 2019, which is the period from April 1, 2018 to March 31, 
2019. 

The following discussion and analysis of our financial condition and results of our operations should be read 

in conjunction with the consolidated financial statements and related notes included elsewhere in this Annual Report 
on Form 10-K. This discussion contains forward-looking statements that are based on the beliefs of our 
management, as well as assumptions made by, and information currently available to, our management. Our actual 
results could differ materially from those discussed below. Factors that could cause or contribute to such differences 
include, but are not limited to, those identified below, and those discussed in the sections titled “Item 1A. Risk 
Factors” and “Cautionary Statement About Forward-Looking Statements” included elsewhere in this Annual 
Report on Form 10-K. Please read the following discussion together with the sections titled “Item 1A. Risk 
Factors,” “Item 6. Selected Financial and Operating Data” and our consolidated financial statements, including 
the related notes, included in “Item 8. Financial Statements and Supplementary Data” of this Form 10-K. 

We consolidate all of our joint ventures for purposes of GAAP, except for our South American Joint Venture 

and our former Tigre-ADS USA Joint Venture. 

Overview 

We are the leading manufacturer of high performance thermoplastic corrugated pipe, providing a 
comprehensive suite of water management products and superior drainage solutions for use in the underground 
construction and infrastructure marketplace. Our innovative products are used across a broad range of end markets 
and applications, including non-residential, residential, agriculture and infrastructure applications. We have 
established a leading position in many of these end markets by leveraging our national sales and distribution 
platform, our overall product breadth and scale and our manufacturing excellence. In the United States, our national 
footprint combined with our strong local presence and broad product offering make us the leader in an otherwise 
highly fragmented sector comprised of many smaller competitors. We believe the markets we serve in the United 
States represent approximately $11 billion of annual revenue opportunity. In addition, we believe the increasing 
acceptance of thermoplastic pipe products in international markets represents an attractive growth opportunity. 

Our products are generally lighter, more durable, more cost effective and easier to install than comparable 
alternatives made with traditional materials. Following our entrance into the non-residential construction market 
with the introduction of N-12 corrugated polyethylene pipe in the late 1980s, our pipe has been displacing traditional 
materials, such as reinforced concrete, corrugated steel and PVC, across an ever expanding range of end markets. 
This has allowed us to consistently gain share and achieve above market growth throughout economic cycles. We 
expect to continue to drive conversion to our products from traditional materials as contractors, civil design 
engineers and municipal agencies increasingly acknowledge the superior physical attributes and compelling value 
proposition of our thermoplastic products. In addition, we believe that overall demand for our products will benefit 
as the regulatory environment continues to evolve. 

Our broad product line includes HDPE pipe, PP pipe and related water management products. Building on our 

core drainage businesses, we have aggressively pursued attractive ancillary product categories such as storm and 
septic chambers, PVC drainage structures, fittings and filters, and water quality filters and separators. We refer to 
these ancillary product categories as Allied Products. Given the scope of our overall sales and distribution platform, 
we have been able to drive growth within our Allied Products and believe there are significant growth opportunities 
going forward. 

Restructuring Activities 

In fiscal 2018, we initiated restructuring activities designed to improve our cost structure, including closing 
four underutilized manufacturing facilities, reducing headcount and eliminating nonessential costs. The following

Strategic Growth and Operational Improvement Initiatives 

In fiscal 2019, we began incurring professional fees in connection with strategic growth and operational 
improvement initiatives. These initiatives include market feasibility assessments, acquisition strategies, operational 
improvement initiatives, which include evaluation of our manufacturing network and improvement initiatives 
associated with various operational support functions. 

Federal Income Tax Reform 

The Tax Act was enacted on December 22, 2017. The Tax Act significantly revises the future ongoing U.S. 
corporate income tax by, among other things, lowering the U.S. corporate income tax rate from 35% to 21%, full 
expensing on qualified property, eliminates the domestic manufacturing deduction and implements a territorial tax 
system. The 21% U.S. corporate income tax rate was effective January 1, 2018. 

The Company previously recognized the provisional tax impacts related to revaluation of deferred tax assets 
and liabilities and deemed repatriated earnings and included these amounts in its financial statements for the year 
ended March 31, 2018. During the fiscal year ended March 31, 2019, the Company finalized the accounting for the 
Tax Act. During the fiscal year ended March 31, 2019, the Company did not make any material adjustments to its 
provisional amounts included in its consolidated financial statements for the year ended March 31, 2018. 

The Company recognized a provisional amount for revaluing its deferred tax attributes resulting in a $16.0 

million tax benefit that was recorded for the fiscal year ended March 31, 2018. On the basis of revised computations 
in filing the U.S. federal tax return during the third quarter, the Company recognized an additional measurement-
period adjustment of $0.4 million to deferred tax expense for the fiscal year ended March 31, 2019. A total deferred 
tax benefit of $15.6 million was recorded. The Company’s accounting for its deferred tax attributes is now complete. 

The Company had $26.5 million of undistributed earnings on its foreign subsidiaries subject to the deemed 

mandatory repatriation. The Company recognized a provisional amount of $5.2 million of income tax expense that 
was recorded for the fiscal year ended March 31, 2018. After the utilization of existing foreign tax credits, the 
Company expected to pay additional U.S. federal taxes of approximately $1.0 million as of the fiscal year ended 
March 31, 2018. On the basis of revised computations in filing the U.S. federal tax return during the third quarter,

Key Factors Affecting Our Results of Operations 

Product Demand - There are numerous factors that influence demand for our products. Our businesses are cyclical 
in nature and sensitive to general economic conditions, primarily in the United States, Canada, Mexico and South 
America. The non-residential, residential, agricultural and infrastructure markets we serve are affected by the 
availability of credit, lending practices, interest rates and unemployment rates. Demand for new homes, farm 
income, commercial development and highway infrastructure spending have a direct impact on our financial 
condition and results of operations. Accordingly, the following factors may have a direct impact on our business in 
the markets in which our products are sold: 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

the strength of the economy; 

the amount and type of non-residential and residential construction; 

funding for infrastructure spending; 

farm income and agricultural land values; 

inventory of improved housing lots; 

changes in raw material prices; 

the availability and cost of credit; 

non-residential occupancy rates; 

commodity prices; and 

demographic factors such as population growth and household formation. 

Product Pricing - The price of our products is impacted by competitive pricing dynamics in our industry as well as 
by raw material input costs. Our industry is highly competitive and the sales prices for our products may vary based 
on the sales policies of our competitors. Raw material costs represent a significant portion of the cost of goods sold 
for our pipe products, or Pipe. We aim to increase our product selling prices in order to cover raw material price 
increases, but the inability to do so could impact our profitability. Movements in raw material, logistics or other 
overhead costs and resulting changes in the selling prices may also impact changes in period-to-period comparisons 
of net sales. 

Material Conversion - Our HDPE and PP pipe and related water management product lines compete with other 
manufacturers of corrugated polyethylene pipe as well as manufacturers of alternative products made with 
traditional materials, such as concrete, steel and PVC. Our net sales are driven by market trends, including the 
continued increase in adoption of thermoplastic corrugated pipe products as a replacement for traditional materials. 
Thermoplastic corrugated pipe is generally lighter, more durable, more cost effective and easier to install than 
comparable products made from traditional materials. We believe customers will continue to acknowledge the 
superior attributes and compelling value proposition of our thermoplastic products and expanded regulatory 
approvals allow for their use in new markets and geographies. In addition, we believe that PP pipe products will also 
help accelerate conversion given the additional applications for which our PP pipe products can be used. 

We believe the adoption of HDPE and PP pipe outside of the United States is still in its early stages and 

represents a significant opportunity for us to continue to increase the conversion to our products from traditional 
products in these markets, including Canada, Mexico and South America where we operate. 

Growth in Allied Products - Our Allied Products include storm and septic chambers, PVC drainage structures, 
fittings, stormwater filters and water separators. These products complement our pipe product lines and allow us to 
offer a comprehensive water management solution to our customers and drive organic growth. Our leading market 
position in pipe products allows us to cross-sell Allied Products effectively. Our comprehensive offering of Allied 

41 

 
 
Table of Contents 

Advanced Drainage Systems, Inc. 

Products also helps us increase pipe sales in certain markets. Our Allied Products are less sensitive to increases in 
resin prices since resin prices represent a smaller percentage of the cost for Allied Products. 

Our leading position in the pipe market has allowed us to increase organic growth of our Allied Products. We 

also expect to expand our Allied Product offerings through acquisitions. 

Raw Material Costs - Our raw material cost and product selling prices fluctuate with changes in the price of resins 
utilized in production. We actively manage our resin purchases and pass fluctuations in the cost of resin through to 
our customers, where possible, in order to maintain our profitability. Fluctuations in the price of crude oil and 
natural gas prices may impact the cost of resin. In addition, changes in and disruptions to existing ethylene or 
polyethylene capacities could also significantly increase resin prices, often within a short period of time, even if 
crude oil and natural gas prices remain low. Our ability to pass through raw material price increases to our 
customers may, in some cases, lag the increase in our costs of goods sold. Sharp rises in raw material prices over a 
short period of time have historically occurred with a significant supply disruption (hurricanes or fires at 
petrochemical facilities), which may increase prices to levels that cannot be fully passed through to customers due to 
pricing of competing products made from different raw materials or the anticipated length of time the raw material 
pricing will stay elevated. For more information regarding risks relating to our raw material costs, see “Item 1A. 
Risk Factors — Risks Relating to Our Business.” 

We currently purchase in excess of 825 million pounds of virgin and recycled resin annually from over 

425 suppliers in North America. As a high-volume buyer of resin, we are able to achieve economies of scale to 
negotiate favorable terms and pricing. Our purchasing strategies differ based on the material (virgin resin versus 
recycled material) ordered for delivery to our production locations. The price movements of the different materials 
also vary, resulting in the need to use a number of strategies to reduce volatility. 

In order to reduce the volatility of raw material costs in the future, our raw material strategies for managing 

our costs include the following: 

• 

• 

• 

• 

increasing the use of less price-volatile recycled HDPE resin in our pipe products in place of virgin resin 
while meeting or exceeding industry standards; 

internally processing an increasing percentage of our recycled HDPE resin in order to closely monitor 
quality and minimize costs (approximately 91% of our recycled HDPE resin was internally processed 
(enhanced) in fiscal 2019); 

managing a resin price risk program that entails both physical fixed price and volume contracts along 
with financial hedges. For our PP virgin resin price exposure, we have the ability to utilize financial 
hedges of propylene as a proxy for PP; and 

maintaining supply agreements with our major resin suppliers that provide multi-year terms and 
volumes that are in excess of our projected consumption. 

We also consume a large amount of energy and other petroleum products in our operations, including the 

electricity we use in our manufacturing process as well as the diesel fuel consumed in delivering a significant 
volume of products to our customers through our in-house fleet. As a result, our operating profit also depends upon 
our ability to manage the cost of the energy and fuel we require, as well as our ability to pass through increased 
prices or surcharges to our customers. 

Seasonality - Our operating results are impacted by seasonality. Historically, sales of our products have been higher 
in the first and second quarters of each fiscal year due to favorable weather and longer daylight conditions 
accelerating construction project activity during these periods while fourth quarter results are impacted by the timing 
of spring in the northern United States and Canada. Seasonal variations in operating results may also be significantly 
impacted by inclement weather conditions, such as cold or wet weather, which can delay projects, resulting in 

42 

 
 
Table of Contents 

Advanced Drainage Systems, Inc. 

decreased net sales for one or more quarters, but we believe that these delayed projects generally result in increased 
net sales during subsequent quarters. 

In the non-residential, residential and infrastructure markets in the northern United States and Canada, the 
construction season typically begins to gain momentum in late March and lasts through November, before winter 
sets in, significantly slowing the construction markets. In the southern and western United States, Mexico, Central 
America and South America, the construction markets are less seasonal. The agricultural drainage market is 
concentrated in the early spring just prior to planting and in the fall just after crops are harvested prior to freezing of 
the ground in winter. 

Currency Exchange Rates - Although we sell and manufacture our products in many countries, our sales and 
production costs are primarily denominated in U.S. dollars. We have wholly-owned facilities in Canada, the 
Netherlands and joint venture facilities in Mexico, Chile, Brazil, Argentina, Colombia and Peru. The functional 
currencies in the areas in which we have wholly-owned facilities and joint venture facilities other than the U.S. 
dollar are the Canadian dollar, Euro, Mexican peso, Chilean peso, Brazilian real and Colombian peso. In fiscal 2019, 
we converted the functional currency of joint venture facilities using the Argentine peso to the Chilean peso. From 
time to time, we use derivatives to reduce our exposure to currency fluctuations. 

Description of our Segments 

We operate a geographically diverse business, serving customers in approximately 80 countries. For fiscal 

2019, approximately 88%, or $1,224.1 million, of net sales were attributable to customers located in the 
United States and approximately 12%, or $160.6 million, of net sales were attributable to customers outside of the 
United States. 

Our operations are organized into two reportable segments based on the markets we serve: Domestic and 
International. We generate a greater proportion of our net sales and gross profit in our Domestic segment, which 
consists of all regions of the United States. We expect the percentage of total net sales and gross profit derived from 
our International segment to continue to increase in future periods as we continue to expand globally. See “Note 21. 
Business Segment Information,” to our audited consolidated financial statements included in “Item 8. Financial 
Statements and Supplementary Data” of this Form 10-K. 

Domestic - Our operating results have been, and will continue to be, impacted by macroeconomic trends in the 
United States. For fiscal 2019, 2018, and 2017, we generated net sales attributable to our Domestic segment of 
$1,224.1 million, $1,174.4 million, and $1,102.2 million, respectively. Unconsolidated sales for our domestic 
unconsolidated joint venture, Tigre-ADS USA, prior to the Company’s divestiture in April 2018 were $17.6 million 
and $18.7 million in fiscal 2018, and 2017, respectively. 

International - Our International segment manufactures and markets products in regions outside of the United 
States, with a growth strategy focused on our owned facilities in Canada and those markets serviced through our 
joint ventures in Mexico and South America. Pipe manufactured in these countries is primarily sold into the same 
region. Our joint venture strategy has provided us with local and regional access to new markets. For fiscal 2019, 
2018, and 2017, we generated net sales attributable to our International segment of $160.6 million, $155.9 million, 
and $155.1 million, respectively. Our investment in the South American Joint Venture is accounted for under the 
equity method and is not consolidated for financial reporting purposes. The unconsolidated sales of the South 
American Joint Venture were $47.6 million, $44.6 million, and $42.2 million, in fiscal 2019, 2018, and 2017, 
respectively. 

Non-GAAP Financial Measures 

EBITDA and Adjusted EBITDA - EBITDA and Adjusted EBITDA, non-GAAP financial measures, have been 
presented in this Annual Report on Form 10-K as supplemental measures of financial performance that are not 
required by, or presented in accordance with GAAP. We calculate EBITDA as net income before interest, income 
taxes and depreciation and amortization. We calculate adjusted EBITDA as net income before interest, income 
taxes, depreciation and amortization, stock-based compensation expense, non-cash charges and certain other 
expenses. 

43 

 
 
Table of Contents 

Advanced Drainage Systems, Inc. 

EBITDA and Adjusted EBITDA are included in this Annual Report on Form 10-K because they are key 
metrics used by management and our Board of Directors to assess our financial performance. EBITDA and Adjusted 
EBITDA are frequently used by analysts, investors and other interested parties to evaluate companies in our 
industry. In addition to covenant compliance and executive performance evaluations, we use EBITDA and adjusted 
EBITDA to supplement GAAP measures of performance to evaluate the effectiveness of our business strategies, to 
make budgeting decisions and to compare our performance against that of other peer companies using similar 
measures. 

EBITDA and Adjusted EBITDA are not GAAP measures of our financial performance and should not be 
considered as alternatives to net income as measures of financial performance or cash flows from operations or any 
other performance measure derived in accordance with GAAP, and it should not be construed as an inference that 
our future results will be unaffected by unusual or non-recurring items. EBITDA and Adjusted EBITDA contain 
certain other limitations, including the failure to reflect our cash expenditures, cash requirements for working capital 
needs and cash costs to replace assets being depreciated and amortized. In evaluating EBITDA and adjusted 
EBITDA, you should be aware that in the future we will incur expenses that are the same as or similar to some of 
the adjustments in this presentation, such as stock-based compensation expense, derivative fair value adjustments, 
and foreign currency transaction losses. Management compensates for these limitations by relying on our GAAP 
results in addition to using EBITDA and adjusted EBITDA supplementally. Our measure of EBITDA and adjusted 
EBITDA are not necessarily comparable to other similarly titled captions of other companies due to different 
methods of calculation. 

For a reconciliation of EBITDA and adjusted EBITDA to net income (loss), the most comparable GAAP 

measure, see “Item 6. Selected Financial and Operating Data.” 

Free Cash Flow - Free Cash Flow is a non-GAAP financial measure used by management and the Company’s 
Board of Directors to assess the Company’s ability to generate cash. Management believes that Free Cash Flow 
provides useful information to investors and others in understanding and evaluating our ability to generate cash flow 
from operations after capital expenditures. Free Cash Flow does not include property, plant and equipment 
purchases completed through financing arrangements. Free Cash Flow should not be considered as an alternative to 
cash flow from operating activities as a measure of liquidity or any other liquidity measure derived in accordance 
with GAAP. Our measure of Free Cash Flow is not necessarily comparable to other similarly titled captions of other 
companies due to different methods of calculation.  

For a reconciliation of Free Cash Flow to Cash flow from operating activities, the most comparable GAAP 

measure, see “Item 6. Selected Financial and Operating Data.”

Domestic gross profit increased $18.3 million, or 6.6%, to $295.7 million for fiscal 2019 as compared to 
$277.4 million during fiscal 2018. The increase was primarily due to the gross profit impact of the net sales increase 
discussed above. The increased sales were offset by an increase in material and transportation costs of $14.4 million 
and increased labor and overhead of $9.1 million. 

 International gross profit increased $6.2 million, or 24.7%, for fiscal 2019 over fiscal 2018 primarily due to 
decreased labor and overhead and the gross profit impact of the net sales increase discussed above. These increases 
were offset by an increase in material and transportation costs. 

Selling expenses - Selling expenses for fiscal 2019 as a percentage of net sales were consistent with fiscal 2018. 

General and administrative expenses - General and administrative expenses for fiscal 2019 decreased as a 
percentage of net sales by 90 basis points over fiscal 2018. The decrease was primarily due to a decrease in 
professional and legal fees of $10.7 million resulting from decreased restatement costs and a legal settlement of $2.0

increased headcount to support growth. 

Loss on disposal of assets and costs from exit and disposal activities – In the fiscal year ended March 31, 2019, we 
recorded $1.6 million of expense related to restructuring activities, including closing one underutilized 
manufacturing facility. In addition, we recorded a loss on other disposals and partial disposals of property, plant and 
equipment of approximately $2.0 million. In the fiscal year ended March 31, 2018, we recorded $11.4 million of 
expense related to restructuring activities, including closing four underutilized manufacturing facilities. In addition, 
we recorded a loss on other disposals and partial disposals of property, plant and equipment of approximately $3.6 
million. See “Note 2. Loss on Disposal of Assets and Costs from Exit and Disposal Activities” for additional 
discussion. 

Intangible amortization - Intangible amortization remained relatively flat as a percentage of net sales in fiscal 2019 
compared to fiscal 2018. 

Interest expense - Interest expense from our debt and capital lease obligations increased $3.4 million or 22.0% in 
fiscal 2019 as compared to fiscal 2018. Interest expense increased primarily due to a $4.5 million change in mark to 
market losses related to our interest rate swaps. This increase was offset by a decrease in our average overall 
outstanding debt of $49.6 million, or 23.9%, for fiscal 2019 compared to the average balance for fiscal 2018. 

Derivative gains and other income, net – Derivative gains and other income, net, decreased to gains of $0.8 million 
in fiscal 2019 compared to gains of $4.0 million in fiscal 2018. The decrease in derivative gains and other income, 
net is primarily due to other non-operating income of $3.0 million for fiscal 2018. 

Income tax expense – For the fiscal years ended March 31, 2019 and 2018, we had effective tax rates of 26.9% and 
14.8%, respectively. The increase in the effective tax rate was primarily due to the impact of Tax Act items not 
affecting the current year and certain other discrete items. See “Note 18. Income Taxes” for additional information. 

Equity in net loss of unconsolidated affiliates - Equity in net loss of unconsolidated affiliates decreased $0.6 million 
to a net loss of $0.1 million for fiscal 2019 compared to a net loss of $0.7 million during fiscal 2018. We are no 
longer invested in Tigre-ADS USA and therefore no longer recognizing a proportionate share of Tigre-ADS USA 
net losses. In addition, net income in the South American Joint Venture decreased to a net loss. 

Net income attributable to noncontrolling interest - Income attributable to noncontrolling interest remained 
relatively flat as a percentage of net sales in fiscal 2019 compared to fiscal 2019. 

The discussion of our results of operations for the fiscal year ended March 31, 2018 compared with the fiscal year 
ended March 31, 2017 can be found in our fiscal 2018 Form 10-K. See Item 7. Management’s Discussion and 
Analysis of Financial Discussion and Results of Operations in our fiscal 2018 Form 10-K for further information on 
our prior period results of operations. 

Liquidity and Capital Resources 

Our primary liquidity requirements are working capital, capital expenditures, debt service, and dividend 

payments for our convertible preferred stock and common stock. We have historically funded, and expect to 
continue to fund, our operations primarily through internally generated cash flow, debt financings, equity issuance 
and capital and operating leases. From time to time we may explore additional financing methods and other means 
to raise capital. There can be no assurance that any additional financing will be available to us on acceptable terms 
or at all. 

As of March 31, 2019, we had $6.1 million in cash that was held by our foreign subsidiaries. Prior to the Tax 
Act, our intent was to indefinitely reinvest our earnings in foreign subsidiaries with the exception of cash dividends 
paid by our ADS Mexicana joint venture. As a result of the Tax Act, we continue to evaluate our strategy with 
regard to foreign cash, but our earnings in foreign subsidiaries still remain indefinitely reinvested.

Advanced Drainage Systems, Inc. 

In February 2017, our Board of Directors authorized the repurchase of up to $50 million of our common stock. 

Repurchases of common stock will be made in accordance with applicable securities laws. The stock repurchase 
program does not obligate us to acquire any particular amount of common stock and may be suspended or 
terminated at any time at our discretion. During fiscal 2018, we repurchased 400,000 shares of common stock at a 
cost of $7.9 million. There were no repurchases of common stock during fiscal 2019. 

Working Capital and Cash Flows 

During fiscal 2019, our net decrease in cash amounted to $8.7 million compared to a net increase of 
$11.1 million during fiscal 2018. Our source of funds in fiscal 2019 was primarily driven by an increase in cash 
provided by operating activities due to decreased accounts payable, accrued expenses, other liabilities, increased 
receivables. Also payments of long-term debt and revolving credit facility, cash dividend payments and payments of 
capital lease obligations impacted our cash position. Our source of funds in fiscal 2018 was primarily driven by an 
increase in cash provided by operating activities. Our use of cash in fiscal 2018 was primarily driven by decreased 
accounts payable, accrued expenses, other liabilities, increased receivables and our long-term debt restructuring. Our 
source of funds in fiscal 2017 was primarily driven by a decrease in cash used in financing activities offset by 
increased cash used in investing activities and a decrease in cash used by operations.  

As of March 31, 2019, we had $491.0 million in liquidity, including $8.9 million of cash, $407.1 million in 

borrowings available under our Secured Bank Loan and $75.0 million under the senior notes, described below. We 
believe that our cash on hand, together with the availability of borrowings under our Secured Bank Loan and other 
financing arrangements and cash generated from operations, will be sufficient to meet our working capital 
requirements, anticipated capital expenditures, scheduled interest payments on our indebtedness and dividend 
payment requirement for our convertible preferred stock for at least the next twelve months. 

As of March 31, 2019, we had consolidated indebtedness (excluding capital lease obligations) of 

approximately $236.8 million, a decrease of $63.9 million compared to March 31, 2018. 

Working Capital - Working capital is an indication of liquidity and potential need for short-term funding. We define 
working capital as current assets less current liabilities. 

Working capital increased to $260.2 million as of March 31, 2019, from $237.2 million as of March 31, 2018, 

primarily due to an increase in receivables of $15.0 million and a decrease in accounts payable of $11.9 million. 

Working capital increased to $237.2 million as of March 31, 2018, from $184.8 million as of March 31, 2017, 

primarily due to a decrease in accounts payable of $16.4 million, the reclassification of $11.9 million due to the 
modification of the liability-classified stock-based awards, as discussed in “Note 17. Stock-Based Compensation”, 
an increase in cash of $11.1 million and a decrease of $10.9 million of the current debt obligations maturities related 
to the refinancing of the Secured Bank Loans and Senior Notes Payable, as discussed in “Note 13. Debt.” 

Operating Cash Flows - During fiscal 2019, cash provided by operating activities was $151.7 million as compared 
with cash provided by operating activities of $137.1 million for fiscal 2018. Cash flow from operating activities 
during fiscal 2019 was primarily impacted by increased income from continuing operations including decreased 
restructuring costs.  

During fiscal 2018, cash provided by operating activities was $137.1 million as compared with cash provided 
by operating activities of $104.2 million for fiscal 2017. Cash flow from operating activities during fiscal 2018 was 
primarily impacted by increased income from continuing operations including decreased restatement related costs. 

Investing Cash Flows - During fiscal 2019, cash used for investing activities was $42.5 million, primarily due to 
$43.4 million for capital expenditures and additions to capitalized software. 

During fiscal 2018, cash used for investing activities was $30.4 million, primarily due to $41.7 million for 

capital expenditures and additions to capitalized software, and $2.0 million for the acquisition of Duraslot, Inc. The 
Company received $13.6 million of proceeds from the sale of corporate-owned life insurance.

Advanced Drainage Systems, Inc. 

During fiscal 2017, cash used for investing activities was $61.3 million, primarily due to $46.7 million for 
capital expenditures and additions to capitalized software, and $8.6 million for the acquisition of Plastic Tubing 
Industries (“PTI”) and $4.6 million for the purchase of equipment through financing. 

Financing Cash Flows - During fiscal 2019, cash used in financing activities was $117.7 million, primarily for net 
debt payments of $62.1 million related to the repayments of the Secured Bank Loans and Senior Notes Payable, 
payments on our capital lease obligations of $24.3 million, dividend payments of $26.1 million and the acquisition 
of noncontrolling interest in BaySaver of $8.8 million. 

During fiscal 2018, cash used in financing activities was $95.0 million, primarily for net debt payments of 
$46.8 million related to the refinancing of the Secured Bank Loans and Senior Notes Payable, as discussed in “Note 
13. Debt,” payments on our capital lease obligations of $24.2 million, dividend payments of $18.5 million and 
repurchases of common stock of $7.9 million. 

During fiscal 2017, cash used in financing activities was $42.8 million, primarily for net debt payments of 
$5.1 million, payments on our capital lease obligations of $21.8 million and dividend payments of $16.8 million. 

Capital Expenditures 

Capital expenditures totaled $43.4 million for fiscal 2019. Our capital expenditures were used primarily to 

support facility expansions, equipment replacements, our recycled resin initiatives and technology. For fiscal year 
ended March 31, 2019, our most significant capital expenditures were $10.8 million for increased capacity related to 
manufacturing facility expansion and additional production lines, as well as $4.8 million for additional processing 
and utilization of recycled resin. 

Capital expenditures totaled $41.7 million for fiscal 2018. Our capital expenditures were used primarily to 

support facility expansions, equipment replacements, our recycled resin initiatives and technology. For fiscal year 
ended March 31, 2018, our most significant capital expenditures were $8.4 million for increased capacity related to 
the opening of the manufacturing facility in Harrisonville, MO and $3.7 million related to the implementation of 
three software solutions to support sales growth and operating effectiveness initiatives. 

Capital expenditures totaled $46.7 million for fiscal 2017. Our capital expenditures were used primarily for 

major plant equipment replacements, new equipment to provide capacity additions, facility expansions and yard 
upgrades, our recycled resin initiatives and capitalized software. Our most significant capital expenditures 
specifically for increased capacity was $7.5 million in fiscal 2017 for the opening of our new manufacturing facility 
in Harrisonville, MO. 

We currently anticipate that we will make capital expenditures of approximately $55 to 65 million in fiscal 

2020. Such capital expenditures are expected to be financed using funds generated by operations. 

Special Dividend 

During the first quarter of fiscal 2020, the Board of Directors approved a special dividend of $1.00 per share 

payable on June 14, 2019 to stockholder of record at the close of business on June 3, 2019. The total special 
dividend payment is expected to be approximately $75 million. The dividend will be used to pay back a portion of 
the ESOP loan resulting in approximately 12 million shares of redeemable convertible preferred stock being 
allocated to ESOP participants. 

Employee Stock Ownership Plan (“ESOP”) 

The Company established the Advanced Drainage Systems, Inc. ESOP (the “ESOP” or the “Plan”) effective 

April 1, 1993 to enable eligible employees to acquire stock ownership in ADS in the form of redeemable convertible 
preferred shares. The Plan was funded by an existing tax-qualified profit-sharing retirement plan, as well as a 30-
year term loan from ADS. Within 30 days following the repayment of the ESOP loan, which will occur no later than 
March 2023, the ESOP committee can direct the shares of redeemable convertible preferred stock owned by the 
ESOP to be converted into shares of the Company’s common stock.  

49 

 
 
Table of Contents 

Advanced Drainage Systems, Inc. 

The Company is obligated to make contributions to the Plan, which, when aggregated with the Plan’s 
dividends, equal the amount necessary to enable the Plan to make its regularly scheduled payments of principal and 
interest due on its term loan to ADS. Compensation expense is recognized based upon the average annual fair value 
of the shares during the period which ADS receives payments on the term loan, and the number of ESOP shares 
allocated to participant accounts. 

As disclosed in “Note 16. Employee Benefit Plans”, redeemable convertible preferred stock can convert to 
common stock upon retirement, disability, death, or vested terminations over the life of the Plan. As stated above, 
within 30 days following the repayment of the ESOP loan, all redeemable convertible preferred stock will be 
converted to common stock, which will be no later than March 2023.  

Following the repayment of the ESOP loan discussed above, the ESOP’s conversion of redeemable 

convertible preferred stock into common stock will impact on the Company’s net income, net income per share and 
common shares outstanding as follows (with the outstanding shares of common stock being approximately 31% 
greater after conversion): 

Impact on Net Income – Absent any other participating securities, the Company will no longer be required to 

apply the two-class method to determine Net income per share once all of the redeemable convertible preferred 
stock is converted into common stock. After the preferred shares are fully allocated upon the repayment of the ESOP 
loan and all of the redeemable convertible preferred stock is converted into common stock, the Company will no 
longer incur the fair value of ESOP deferred compensation attributable to the shares of redeemable convertible 
preferred shares. 

The impact of the ESOP on net income includes the fair value of ESOP deferred compensation attributable to 

the shares of redeemable convertible preferred stock allocated to employee ESOP accounts during the applicable 
period, which is a non-cash charge to our earnings and not deductible for income tax purposes.

Debt and Capitalized Lease Obligations 

See “Note 6. Leases” and “Note 13. Debt” to our consolidated financial statements included in “Item 8. 
Financial Statements and Supplementary Data” for a discussion of the Company’s financing transactions, including 
the Secured Bank Loans, the Senior Notes and the Company’s capital lease obligations. 

Financing Transactions 

Secured Bank Loans - On September 24, 2010, we entered into a credit agreement with PNC Bank, National 
Association, or PNC, as administrative agent, and lender parties thereto. The credit agreement, as amended and 
restated on June 12, 2013 and subsequently further amended, provides for our Bank Term Loans consisting of (i) the 
Revolving Credit Facility providing for revolving loans and letters of credit of up to a maximum aggregate principal 
amount of $325 million, (ii) the Term Loan Facility providing for the Term Loans in an aggregate original principal 
amount of $100 million, and (iii) the ADS Mexicana Revolving Credit Facility, described below, which is more 
fully described in our fiscal 2017 Form 10-K. On June 22, 2017, we entered into a Second Amended and Restated 
Credit Agreement with PNC, which amends and restates the agreement dated as of June 12, 2013, to provide us a

$550 million Revolving Credit Facility, which is more fully described in “Note 13. Debt” to the Consolidated 
Financial Statements. 

As of March 31, 2019, the outstanding principal drawn on the Revolving Credit Facility was $134.4 million, 

with $407.1 million available to be drawn on the U.S. facility, net of $8.5 million of outstanding letters of credit. 

ADS Mexicana Revolving Credit Facility - On September 24, 2010, ADS Mexicana entered into a credit agreement 
with PNC, as administrative agent, and lender parties thereto. The credit agreement, as amended and restated on 
June 12, 2013 and subsequently further amended, provides for revolving loans and letters of credit of up to a 
maximum aggregate principal amount of $12.0 million. On June 22, 2018, the Company’s $12.0 million Revolving 
Credit Facility – ADS Mexicana matured. At June 22, 2018, there were no borrowings under the Revolving Credit 
Facility – ADS Mexicana. 

ADS Mexicana’s Revolving Credit Facility was replaced by an Intercompany Revolving Credit Promissory 

Note (the “Intercompany Note”) with a capacity of $12.0 million. The Intercompany Note matures on June 22, 2022. 
The other joint venture partner indemnifies us for 49% of any unpaid borrowing. The interest rates under the 
Intercompany Note are determined by certain base rates or LIBOR rates plus an applicable margin based on the 
Leverage Ratio. As of March 31, 2019, there were no borrowings under the Intercompany Note. 

Senior Notes - On December 11, 2009, we entered into a private shelf agreement with Prudential Investment 
Management Inc., or Prudential, which agreement, as amended and restated on September 24, 2010 and 
subsequently further amended, provides for the issuance by us of senior secured promissory notes to Prudential or its 
affiliates from time to time in the aggregate principal amount up to $100 million. On June 22, 2017, we entered into 
the Second Amended and Restated Private Shelf Agreement with Prudential, which amends and restates the 
agreement dated as of September 24, 2010, to provide for the issuance of secured senior notes to Prudential or its 
affiliates from time to time in the aggregate principal amount of up to $175 million, which is more fully described in 
“Note 13. Debt” to the Consolidated Financial Statements. We have $75 million available for issuance of senior 
notes under the private shelf agreement. At March 31, 2019, the outstanding principal balance on these notes was 
$100 million. 

Covenant Compliance 

Our outstanding debt agreements and instruments contain various restrictive covenants including, but not 

limited to, limitations on additional indebtedness and capital distributions, including dividend payments. The two 
primary debt covenants of the amended ADS Revolving Credit Facility and Senior Notes include a Leverage Ratio 
and an Interest Coverage Ratio maintenance covenant. The Credit Agreement Leverage Ratio generally requires that 
at the end of any fiscal quarter, for the four fiscal quarters then ended, we will not permit the ratio of its total 
consolidated indebtedness to our Consolidated EBITDA (as defined in the Credit Agreement) to be greater than 4.00 
to 1.00 (or 4.25 to 1.00 as of the date of any acquisitions permitted under the Credit Agreement for which the 
aggregate consideration is $100.0 million or greater). The Credit Agreement Interest Coverage Ratio generally 
requires that at the end of any fiscal quarter, for the four fiscal quarters then ended, we will not permit the ratio of 
Consolidated EBITDA to our consolidated interest expense payable during such period to be less than 3.00 to 1.00. 

The primary debt covenant of the ADS Mexicana Revolving Credit Facility is a Leverage Ratio maintenance 
covenant. For any relevant period of determination, the Leverage Ratio is calculated by dividing Total Consolidated 
Indebtedness (funded debt plus guarantees) by Consolidated EBITDA, as defined by the credit facility. The current 
upper limit is 4.0 times. 

For further information, see “Note 13. Debt” to the Consolidated Financial Statements. We were in 

compliance with our debt covenants as of March 31, 2019.

Off-Balance Sheet Arrangements 

We do not have any off-balance sheet arrangements, with the exception of the guarantee of 50% of certain 

debt of our unconsolidated South American Joint Venture, as further discussed in “Note 12. Related Party 
Transactions” of our Consolidated Financial Statements included in “Item 8. Financial Statements and 
Supplementary Data,” of this Form 10-K. Our maximum potential obligation under this guarantee totals $11 million 
as of March 31, 2019. The maximum borrowing permitted under the South American Joint Venture’s credit facility 
is $22 million. As of March 31, 2019, our South American Joint Venture had approximately $12.3 million of 
outstanding debt subject to our guarantee, resulting in our guarantee of 50%, or $6.2 million, of that amount. We do 
not believe that this guarantee will have a current or future effect on our financial condition, results of operations, 
liquidity, or capital resources. 

Critical Accounting Policies and Estimates 

Our discussion and analysis of financial condition and results of operations are based on our consolidated 
financial statements, which have been prepared in accordance with GAAP. The preparation of the consolidated 
financial statements requires management to make estimates and judgments that affect the reported amounts in our 
consolidated financial statements and accompanying notes. 

Certain of our accounting policies involve a higher degree of judgment and complexity in their application, 

and therefore, represent the critical accounting policies used in the preparation of our financial statements. If 
different assumptions or conditions were to prevail, the results could be materially different from our reported 
results. We believe the following accounting policies may involve a higher degree of judgment and complexity in 
their application and represent the critical accounting policies used in the preparation of our financial statements. For

Policy 
Goodwill- Goodwill is reviewed 
annually for impairment as of 
March 31 or whenever events or 
changes in circumstances indicate 
the carrying value may not be 
recoverable. The fair value of 
goodwill is determined by 
considering both the income and 
market approach.  

Judgments and Estimates 
Determining the fair value of a 
reporting unit is judgmental in 
nature and involves the use of 
significant estimates and 
assumptions. These estimates and 
assumptions include revenue 
growth rates and operating margins 
used to calculate projected future 
cash flows, risk-adjusted discount 
rates, future economic and market 
conditions, and determination of 
appropriate market comparables. 
The fair value estimates are based 
on assumptions management 
believes to be reasonable, but are 
inherently uncertain. 

Effect if Actual Results Differ 
from Assumptions 
We performed our annual 
impairment test for goodwill as of 
March 31, 2019. We determined for 
our Domestic reporting unit that it 
was not more likely than not that 
the fair value of the reporting unit 
was less than its carrying value. We 
determined for the remaining 
goodwill that the fair value 
exceeded the carrying value for 
each of our reporting units. 
Accordingly, we did not incur any 
impairment charges for goodwill in 
fiscal 2019, 2018, or 2017. Future 
events and unanticipated changes to 
assumptions could require a 
provision for impairment in a future 
period.

Effect if Actual Results Differ 
from Assumptions 

We did not record any impairment 
charges for definite-lived intangible 
assets in fiscal 2019, 2018, or 
2017. Future events and 
unanticipated changes to 
assumptions could require a 
provision for impairment in a future 
period. 

We performed our annual 
impairment test for indefinite-lived 
intangible assets as of March 31, 
2019. We determined for our 
indefinite-lived intangible assets 
that it was not more likely than not 
that the fair value of the asset was 
less than its carrying value. We 
determined the fair value of the 
asset exceeded the carrying value. 
Accordingly, we did not incur any 
impairment charges for indefinite-
lived intangible assets in fiscal 
2019, 2018 or 2017. Future events 
and unanticipated changes to 
assumptions could require a 
provision for impairment in a future

Policy 

Judgments and Estimates 

Determining the fair value of the 
definite-lived and indefinite-lived 
intangible assets is judgmental in 
nature and involves the use of 
significant estimates and 
assumptions. Future events and 
unanticipated changes to 
assumptions could require a 
provision for impairment in a future 
period. 

Definite-lived intangible assets-
Definite-lived intangible assets are 
tested for recoverability whenever 
events or changes in circumstances 
indicate that carrying amounts of 
the asset group may not be 
recoverable. Asset groups are 
established primarily by 
determining the lowest level of 
cash flows available. If the 
estimated undiscounted future cash 
flows are less than the carrying 
amounts of such assets, an 
impairment loss is recognized to 
the extent the fair value of the asset 
less any costs of disposition is less 
than the carrying amount of the 
asset.  

Indefinite-lived intangible assets-
Indefinite-lived intangible assets 
are tested for impairment annually 
as of March 31 or whenever events 
or changes in circumstances 
indicate the carrying value may be 
greater than fair value. Determining 
the fair value of these assets is 
judgmental in nature and involves 
the use of significant estimates and 
assumptions. We base our fair 
value estimates on assumptions we 
believe to be reasonable, but that 
are inherently uncertain. To 
estimate the fair value of these 
indefinite-lived intangible assets, 
we use an income approach, which 
utilizes a market derived rate of 
return to discount anticipated 
performance. An impairment loss is 
recognized when the estimated fair 
value of the intangible asset is less 
than the carrying value.

Policy 
Revenue Recognition- We generate 
revenue by selling pipe and related 
water management products 
primarily to distributors, retailers, 
buying groups and co-operative 
buying groups. Products are 
shipped predominately by our 
internal fleet, and we do not 
provide any additional revenue 
generating services after product 
delivery. Payment terms and 
conditions vary by contract. 

Revenue is recognized at the point 
in-time obligations under the terms 
of a contract with a customer are 
satisfied, which generally occurs 
upon the transfer of control of the 
promised goods. In substantially all 
of our contracts with customers, 
control is transferred to the 
customer upon delivery. We 
recognize revenue in an amount 
that reflects the consideration we 
expect to be entitled to in exchange 
for those goods or services. 

Employee Stock Ownership Plan 
(“ESOP”)- When shares of 
convertible preferred stock are 
allocated to the ESOP stock 
accounts of ESOP participants, we 
reduce the amount of deferred 
compensation reflected in Deferred 
compensation — unearned ESOP 
shares in mezzanine equity.   

Judgments and Estimates 
We estimate and allocate variable 
consideration based on numerous 
factors, including the customer 
agreements and past transaction 
history. 

Effect if Actual Results Differ 
from Assumptions 
If our historical experience differs 
from future experience, our 
estimates of variable consideration 
could differ. 

Shares of convertible preferred 
stock are valued based on an annual 
valuation for the ESOP by an 
independent third-party appraisal 
firm as required by the Plan. 

As the value of the shares increase, 
it could result in a significant 
increase in compensation expense.  

56 

 
 
 
 
 
Effect if Actual Results Differ 
from Assumptions 
All current stock-based awards 
qualify for equity classification. 
Changes in the assumptions utilized 
to determine the fair value could 
cause fluctuations in the stock-based 
compensation expense for future 
grants.

Policy 
Stock-Based Compensation Plan-
Equity-classified awards are 
measured based on the grant-date 
estimated fair value of each award, 
net of estimated forfeitures, at each 
relevant reporting date for 
accounting purposes. 
Compensation expense is 
recognized on a straight-line basis 
over the employee’s requisite 
service period, which is generally 
the vesting period of the grant. 

Judgments and Estimates 
The fair value of each stock option 
granted is estimated using the Black-
Scholes option pricing model. 
Determining the fair value of stock 
options under the Black-Scholes 
option-pricing model requires 
judgment, common stock volatility, 
expected term of the awards, 
dividend yield and the risk-free 
interest rate. The assumptions used 
in calculating the fair value of stock 
options represent our best estimates, 
based on management’s judgment 
and subjective future expectations. 
These estimates involve inherent 
uncertainties. We developed our 
assumptions the following: 

• 
• 
• 
• 

Volatility.  
Expected term.  
Risk-free interest rate. 
Dividend yield.

Accounting Policies” to our consolidated financial statements included in “Item 8. Financial Statements and 
Supplementary Data.” 

Item 7A. 

Quantitative and Qualitative Disclosures About Market Risk 

We are subject to various market risks, primarily related to changes in interest rates, credit risk, raw material 

supply prices, and, to a lesser extent, foreign currency exchange rates. Our financial position, results of operations or 
cash flows may be negatively impacted in the event of adverse movements in the respective market rates or prices in 
each of these risk categories. Our exposure in each category is limited to those risks that arise in the normal course 
of business, as we do not engage in speculative, non-operating transactions. 

Interest Rate Risk 

We are subject to interest rate risk associated with our bank debt. Changes in interest rates impact the fair 
value of our fixed-rate debt, but there is no impact to earnings and cash flow. Alternatively, changes in interest rates 
do not affect the fair value of our variable-rate debt, but they do affect future earnings and cash flow. The Revolving 
Credit Facility and the Term Note, notes bear variable interest rates. The Revolving Credit Facility and Term Note 
bear interest either at LIBOR or the Prime Rate, at our option, plus applicable pricing margins. A 1.0% increase in 
interest rates on our variable-rate debt would increase our annual forecasted interest expense by approximately 
$0.3 million based on our borrowings as of March 31, 2019. Assuming the Revolving Credit Facility is fully drawn 
and considering our interest rate swap, each 1.0% increase or decrease in the applicable interest rate would change 
our interest expense by approximately $4.5 million, as of March 31, 2019.  

Credit Risk 

Financial instruments that potentially subject us to a concentration of credit risk consist principally of 

accounts receivable. We provide our products to customers based on an evaluation of the customers’ financial 
condition, generally without requiring collateral. Exposure to losses on receivables is principally dependent on each 

57 

 
 
 
 
 
 
Table of Contents 

Advanced Drainage Systems, Inc. 

customer’s financial condition. We monitor the exposure for credit losses and maintain allowances for anticipated 
losses. Concentrations of credit risk with respect to our accounts receivable are limited due to the large number of 
customers comprising our customer base and their dispersion among many different geographies. One customer has 
an accounts receivable balance equal to approximately 19% of our Receivables balance as of March 31, 2019. 

Raw Material and Commodity Price Risk 

Our primary raw materials used in the production of our products are HDPE and PP resins. As these resins are 

hydrocarbon-based materials, changes in the price of feedstocks, such as crude oil derivatives and natural gas 
liquids, as well as changes in the market supply and demand may cause the cost of these resins to fluctuate 
significantly. Raw materials account for the majority of our cost of goods sold. Given the significance of these costs 
and the inherent volatility in supplier pricing, our ability to reflect these changes in the cost of resins in our product 
selling prices in an efficient manner contributes to the management of our overall risk and the potential impact on 
our results of operations. A 1% increase in the price of resin would increase our cost of goods sold by approximately 
$4 million. 

We have a resin price risk management program with physical fixed price contracts which are designed to 
apply to a significant portion of our annual virgin resin purchases. We also maintain supply agreements with our 
major resin suppliers that provide multi-year terms and volumes that are in excess of our projected consumption. 
These supply agreements generally do not contain minimum purchase volumes or fixed prices. Accordingly, our 
suppliers may change their selling prices or other relevant terms on a monthly basis, exposing us to pricing risk. To 
manage this risk for our polypropylene virgin resin price exposure, we utilize financial hedges of propylene as a 
proxy for polypropylene. Historically, the month to month change in market-based pricing has been very similar 
between propylene and polypropylene. 

Inflation Risk 

Our cost of goods sold is subject to inflationary pressures and price fluctuations of the raw materials we use, 

primarily HDPE and PP resins. Historically, we have generally been able, over time, to recover the effects of 
inflation and price fluctuations through sales price increases and production efficiencies related to technological 
enhancements and improvements. However, we cannot reasonably estimate our ability to successfully recover any 
price increases. 

Foreign Currency Exchange Rate Risk 

We have operations in countries outside of the United States, which primarily use the respective local foreign 

currency as their functional currency. Each of these operations may enter into contractual arrangements with 
customers or vendors that are denominated in currencies other than its respective functional currency. Consequently, 
our results of operations may be affected by exposure to changes in foreign currency exchange rates and economic 
conditions in the regions in which we sell or distribute our products. Exposure to variability in foreign currency 
exchange rates from these transactions is managed, to the extent possible, by natural hedges which result from 
purchases and sales occurring in the same foreign currency within a similar period of time, thereby offsetting each 
other to varying degrees. 

In addition to the foreign currency transaction-related gains and losses that are reflected within the results of 

operations, we are subject to foreign currency translation risk, as the financial statements for our foreign subsidiaries 
are measured and recorded in the respective subsidiary’s functional currency and translated into U.S. dollars for 
consolidated financial reporting purposes. The resulting translation adjustments are recorded net of tax impact in the 
Consolidated Statements of Comprehensive (Loss) Income.

Changes in and Disagreements with Accountant on Accounting and Financial Disclosure 

None. 

Item 9A.  Controls and Procedures  

Evaluation of Disclosure Controls and Procedures  

Under the supervision and with the participation of our management, including our Chief Executive Officer 

and our Chief Financial Officer, we evaluated 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, as amended (the “Exchange Act”), as 
of March 31, 2019. Disclosure controls and procedures are designed to ensure that information required to be 
disclosed in our reports filed or submitted under the Exchange Act are recorded, processed, summarized and 
reported, within the time periods specified under Securities Exchange Commission (“SEC”) rules and forms. 
Management recognizes that any controls and procedures, no matter how well designed and operated, can provide 
only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in 
evaluating the cost-benefit relationship of possible controls and procedures. 

Based on the evaluation of our disclosure controls and procedures, our Chief Executive Officer and Chief 
Financial Officer concluded that our disclosure controls and procedures were not effective as of March 31, 2019 
because of the material weakness in our internal control over financial reporting, as further described below. 

Management’s Report on Internal Control over Financial Reporting 

Management is responsible for establishing and maintaining adequate internal control over financial reporting, 

as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). 

Because of its inherent limitations, internal control over financial reporting may not prevent or detect all 
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 policies or 
procedures may deteriorate. 

Management, including our Chief Executive Officer and our Chief Financial Officer, assessed the 
effectiveness of our internal control over financial reporting as of March 31, 2019. 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). A material weakness in internal controls is a 
deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a 
reasonable possibility that a material misstatement of our annual or interim financial statements will not be 
prevented or detected on a timely basis. Because of its inherent limitations, even appropriate internal control over 
financial reporting may not prevent or detect misstatements. 

Based on this assessment, management has concluded that the Company did not maintain effective internal 

control over financial reporting as of March 31, 2019, due to the fact that we had a material weakness in our internal 
control over financial reporting in the control environment of our consolidated joint venture affiliate, ADS 
Mexicana. This material weakness was a result of the Company’s findings to date as part of an internal 
investigation, under the guidelines of the Company’s Code of Business Conduct and Ethics, into ADS Mexicana’s 
senior management’s ethical and business conduct, which included consideration of compliance of certain products 
with Mexican laws and regulations. The material weakness in the control environment of ADS Mexicana impacts 
the overall effectiveness of our internal controls over financial reporting. 

Deloitte & Touche LLP, our independent registered public accounting firm, has issued an audit report on the 
effectiveness of our internal control over financial reporting as of March 31, 2019 and this report is included herein.

Remediation Process 

We have commenced a process to remediate the underlying cause of the material weakness described above 

and enhance our internal controls over financial reporting at ADS Mexicana. The remediation actions we anticipate 
taking include the following: 

•  The Company will take disciplinary actions relating to ADS Mexicana senior management where 

appropriate. 

•  Evaluate the experience and training of ADS Mexicana personnel and hire qualified employees or 

consultants as necessary 

•  Provide supplemental training on the Company’s Code of Business Conduct and Ethics to ADS Mexicana 

personnel; 

• 

• 

Implement additional oversight controls related to ADS Mexicana’s activities, including reports to the 
Ethics Hotline 

Implement additional controls relating to ADS Mexicana segregation of duties and information technology 
access 

The material weaknesses did not result in a material misstatement in the financial statements included in our 

Annual Report on Form 10-K for the year ended March 31, 2019 or previously issued financial statements. 

We believe the foregoing efforts will effectively remediate the material weakness described above. As we continue 
to evaluate and work to improve our internal control over financial reporting, we may take additional measures to 
address this control deficiency or modify the remediation plan described above. We cannot assure you, however, 
when we will remediate such weakness, nor can we be certain of whether additional actions will be required. See 
above under Item 1A, “Risk Factors — Our failure to maintain effective disclosure controls and internal control over 
financial reporting could adversely affect our business, financial position and results of operations.” 

Changes in Internal Control over Financial Reporting  

Other than the identification of a material weakness in the control environment of ADS Mexicana as described 
above, there were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-
15(f) of the Exchange Act) that occurred during the three months ended March 31, 2019 that has materially affected, 
or is reasonably likely to materially affect, internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Stockholders and the Board of Directors of Advanced Drainage Systems, Inc. 

Opinion on the Financial Statements 

We have audited the accompanying consolidated balance sheets of Advanced Drainage Systems, Inc. and 
subsidiaries (the "Company") as of March 31, 2019 and 2018 , the related consolidated statements of  operations, 
comprehensive income (loss), stockholders' equity (deficit) and mezzanine equity, and cash flows, for each of the 
three years in the period ended March 31, 2019, and the related notes and the financial statement schedule listed in 
the Index at Item 15 (collectively referred to as the "financial statements"). In our opinion, the financial statements 
present fairly, in all material respects, the financial position of the Company as of March 31, 2019 and 2018, and the 
results of its operations and its cash flows for each of the three years in the period ended March 31, 2019, in 
conformity with accounting principles generally accepted in the United States of America. 

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States) (PCAOB), the Company's internal control over financial reporting as of March 31, 2019, based on criteria 
established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring 
Organizations of the Treadway Commission and our report dated May 30, 2019, expressed an adverse opinion on 
the Company's internal control over financial reporting because of a material weakness.  

Basis for Opinion 

These financial statements are the responsibility of the Company's management. Our responsibility is to express an 
opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with 
the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal 
securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the 
PCAOB. 

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and 
perform the audit to obtain reasonable assurance about whether the financial statements are free of material 
misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of 
material misstatement of the financial statements, whether due to error or fraud, and performing procedures that 
respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and 
disclosures in the financial statements. Our audits also included evaluating the accounting principles used and 
significant estimates made by management, as well as evaluating the overall presentation of the financial statements. 
We believe that our audits provide a reasonable basis for our opinion.

 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Stockholders and the Board of Directors of Advanced Drainage Systems, Inc.  

Opinion on Internal Control over Financial Reporting 

We have audited the internal control over financial reporting of Advanced Drainage Systems, Inc.  and subsidiaries 
(the “Company”) as of March 31, 2019, based on criteria established in Internal Control — Integrated Framework 
(2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, 
because of the effect of the material weakness identified below on the achievement of the objectives of the control 
criteria, the Company has not maintained effective internal control over financial reporting as of March 31, 2019, 
based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO. 

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States) (PCAOB), the consolidated financial statements as of and for the year ended March 31, 2019, of the 
Company and our report dated May 30, 2019, expressed an unqualified opinion on those financial statements. 

Basis for Opinion  

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

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and 
perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting 
was maintained in all material respects. Our audit included obtaining an understanding of internal control over 
financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating 
effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered 
necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. 

Definition and Limitations of Internal Control over Financial Reporting 

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

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

Material Weakness  

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, 
such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial 
statements will not be prevented or detected on a timely basis. The following material weakness has been identified 
and included in management's assessment: a material weakness in the internal control over financial reporting in the 
control environment of the Company’s consolidated joint venture affiliate, ADS Mexicana. This material weakness 
was considered in determining the nature, timing, and extent of audit tests applied in our audit of the consolidated 
financial statements and financial statement schedule as of and for the year ended March 31, 2019, of the Company, 
and this report does not affect our report on such financial statements.

ADVANCED DRAINAGE SYSTEMS, INC. AND SUBSIDIARIES 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

1. 

BACKGROUND AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 

Description of Business - Advanced Drainage Systems, Inc. and subsidiaries (collectively referred to as 
“ADS” and the “Company”), incorporated in Delaware, designs, manufactures and markets high performance 
thermoplastic corrugated pipe and related water management products, primarily in North and South America 
and Europe. ADS’s broad product line includes corrugated high-density polyethylene (or “HDPE”) pipe, 
polypropylene (or “PP”) pipe and related water management products. 

The Company’s fiscal year begins on April 1 and ends on March 31. Unless otherwise noted, references to 
“year” pertain to our fiscal year. For example, 2019 refers to fiscal 2019, which is the period from April 1, 
2018 to March 31, 2019. 

The Company is managed based primarily on the geographies in which it operates and reports results of 
operations in two reportable segments. The reportable segments are Domestic and International. 

Principles of Consolidation - The consolidated financial statements include the Company, its wholly-owned 
subsidiaries, its majority owned subsidiaries, and variable interest entities (“VIEs”) of which the Company is 
the primary beneficiary. The Company uses the equity method of accounting for equity investments where it 
exercises significant influence but does not hold a controlling financial interest. Such investments are recorded 
in Other assets in the Consolidated Balance Sheets and the related equity in earnings from these investments 
are included in Equity in net loss of unconsolidated affiliates in the Consolidated Statements of Operations. 
All intercompany balances and transactions have been eliminated in consolidation. 

Estimates - The preparation of consolidated financial statements in conformity with accounting principles 
generally accepted in the United States of America (“GAAP”) requires management to make estimates and 
assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingencies and 
liabilities at the balance sheet date and the reported amounts of revenues and expenses during the reporting 
period. Significant estimates include, but are not limited to, the allowance for doubtful accounts, valuation of 
inventory, useful lives of property, plant and equipment and amortizing intangible assets, determination of the 
proper accounting for leases, valuation of equity method investments, goodwill, intangible assets and other 
long-lived assets for impairment, accounting for stock-based compensation and the ESOP, valuation of the 
redeemable convertible preferred stock, determination of allowances for sales returns, rebates and discounts, 
determination of the valuation allowance, if any, on deferred tax assets, and reserves for uncertain tax 
positions. Management’s estimates and assumptions are evaluated on an ongoing basis and are based on 
historical experience, current conditions and available information. Management believes the accounting 
estimates are appropriate and reasonably determined; however, due to the inherent uncertainties in making 
these estimates, actual results could differ from those estimates. 

Receivables and Allowance for Doubtful Accounts - Receivables include trade receivables, net of an 
allowance for doubtful accounts, and other miscellaneous receivables. Receivables at March 31, 2019 and 
2018 are as follows: 

 (Amounts in thousands) 
Trade receivables 
Other miscellaneous receivables 

Receivables, net 

2019 
170,887      $ 
16,104

2018 

159,291   
12,670   
171,961   

   $ 

   $ 

As of March 31, 2019 and 2018, Other miscellaneous receivables includes insurance recoverables of 
approximately $3.9 million and $3.4 million, respectively, which has a corresponding liability recorded in 
Other accrued liabilities. 

Credit is extended to customers based on an evaluation of their financial condition and collateral is generally 
not required. The evaluation of the customer’s financial condition is performed to reduce the risk of loss. 

F-14

Accounts receivable are evaluated for collectability based on numerous factors, including the length of time 
individual receivables are past due, past transaction history with customers, their credit worthiness and the 
economic environment. This estimate is periodically adjusted when management becomes aware of a situation 
in which doubt the customer does not have the ability or intention to pay its financial obligations (e.g. 
bankruptcy filing). 

Inventories - Inventories are stated at the lower of cost or net realizable value. The Company’s inventories are 
maintained on the first-in, first-out (“FIFO”) method. Costs include the cost of acquiring materials, including 
in-bound freight from vendors and freight incurred for the transportation of raw materials, tooling or finished 
goods between the Company’s manufacturing plants and its distribution centers, direct and indirect labor, 
factory overhead and certain corporate overhead costs related to the production of inventory. The portion of 
fixed manufacturing overhead that relates to capacity in excess of our normal capacity is expensed in the 
period in which it is incurred and is not included in inventory. Net realizable value of inventory is established 
with consideration given to deterioration, obsolescence, and other factors. The Company periodically 
evaluates the carrying value of inventories and adjustments are made whenever necessary to reduce the 
carrying value to net realizable value. 

Property, Plant and Equipment and Depreciation Method - Property, plant and equipment are recorded at 
cost less accumulated depreciation, with the exception of assets acquired through acquisitions, which are 
initially recorded at fair value. Equipment acquired under capital lease is recorded at the lower of fair market 
value or the present value of the future minimum lease payments. Depreciation is computed for financial 
reporting purposes using the straight-line method over the estimated useful lives of the related assets or the 
lease term, if shorter, as follows: 

Buildings and leasehold improvement 
Machinery and production equipment 
Transportation equipment 

Years 
20 to 45 or the lease term if shorter 
3 to 18 
3 to 12 

Costs of additions and major improvements are capitalized, whereas maintenance and repairs that do not 
improve or extend the life of the asset are charged to expense as incurred. When assets are retired or disposed, 
the cost and related accumulated depreciation are removed from the asset accounts and any resulting gain or 
loss is reflected in Loss on disposal of assets and costs from exit and disposal activities in our Consolidated 
Statements of Operations. Construction in progress is also recorded at cost and includes capitalized interest, 
capitalized payroll costs and related costs such as taxes and other fringe benefits. There was no interest 
capitalized during the fiscal year ended March 31, 2019. Interest capitalized was $0.6 million, and $0.6 
million during the fiscal years ended March 31, 2018 and 2017, respectively. 

Goodwill - The Company records acquisitions resulting in the consolidation of an enterprise using the 
acquisition method of accounting. Under this method, the Company records the assets acquired, including 
intangible assets that can be identified, and liabilities assumed based on their estimated fair values at the date 
of acquisition. The purchase price in excess of the fair value of the identifiable assets acquired and liabilities 
assumed is recorded as goodwill. 

Goodwill is reviewed annually for impairment as of March 31 or whenever events or changes in 
circumstances indicate the carrying value may be greater than fair value. If the fair value of the reporting unit 
exceeds the carrying value of the net assets assigned to that unit, goodwill is not considered impaired and the 
Company is not required to perform further testing. If the carrying value of a reporting unit’s goodwill 
exceeds its fair value, then the Company would record an impairment loss equal to the difference. With 
respect to this testing, a reporting unit is a component of the Company for which discrete financial information 
is available and regularly reviewed by management. The fair value of goodwill is determined by considering 
both the income and market approach. Determining the fair value of a reporting unit is judgmental in nature 
and involves the use of significant estimates and assumptions. These estimates and assumptions include 
revenue growth rates and operating margins used to calculate projected future cash flows, risk-adjusted 
discount rates, future economic and market conditions, and determination of appropriate market comparables. 
The fair value estimates are based on assumptions management believes to be reasonable but are inherently

uncertain. For all fiscal years presented, ADS completed a quantitative fair value assessment of the 
International reporting unit and determined no impairment charge was required.  

GAAP allows entities testing goodwill for impairment the option of performing a qualitative assessment 
before calculating the fair value of a reporting unit for the goodwill impairment test. If the qualitative 
assessment is performed, an entity is no longer required to calculate the fair value of a reporting unit unless 
the entity determines that, based on that assessment, it is more likely than not that its fair value is less than its 
carrying amount. ADS completed a quantitative fair value measurement of the Domestic reporting unit in 
fiscal 2016. The test indicated that the fair value of the Domestic reporting unit exceeded the carrying value, 
indicating that no impairment existed. ADS applied the qualitative assessment to the Domestic reporting unit 
for the annual impairment tests performed as of March 31, 2019, 2018 and 2017. For the current year test, 
ADS assessed various assumptions, events and circumstances that would have affected the estimated fair 
value of the reporting unit as compared to its March 31, 2016 quantitative fair value measurement. The results 
of this assessment indicated that it is not more likely than not that the reporting unit fair value is less than the 
reporting unit carrying value. The Company did not incur any impairment charges for goodwill in the fiscal 
years ended March 31, 2019, 2018, and 2017. 

Intangible Assets 

Intangible Assets — Definite-Lived - Definite-lived intangible assets are amortized using the straight-line 
method over their estimated useful lives and are tested for recoverability whenever events or changes in 
circumstances indicate that carrying amounts of the asset group may not be recoverable. Asset groups are 
established primarily by determining the lowest level of cash flows available. If the estimated undiscounted 
future cash flows are less than the carrying amounts of such assets, an impairment loss is recognized to the 
extent the fair value of the asset less any costs of disposition is less than the carrying amount of the asset. 
Determining the fair value of these assets is judgmental in nature and involves the use of significant estimates 
and assumptions. 

Intangible Assets — Indefinite-Lived - Indefinite-lived intangible assets are tested for impairment annually as 
of March 31 or whenever events or changes in circumstances indicate the carrying value may be greater than 
fair value. Determining the fair value of these assets is judgmental in nature and involves the use of significant 
estimates and assumptions. The Company bases its fair value estimates on assumptions it believes to be 
reasonable, but that are inherently uncertain. To estimate the fair value of these indefinite-lived intangible 
assets, the Company uses an income approach, which utilizes a market derived rate of return to discount 
anticipated performance. An impairment loss is recognized when the estimated fair value of the intangible 
asset is less than the carrying value. 

GAAP allows entities testing indefinite-lived intangible assets for impairment the option of performing a 
qualitative assessment before calculating the fair value of the indefinite-lived intangible assets for the 
impairment test. If the qualitative assessment is performed, an entity is no longer required to calculate the fair 
value of an indefinite-lived intangible assets unless the entity determines that, based on that assessment, it is 
more likely than not that its fair value is less than its carrying amount. ADS completed a quantitative fair 
value measurement of indefinite-lived trademarks in March 31, 2016. The test indicated that the fair value of 
the indefinite-lived trademarks substantially exceeded the carrying value, indicating that no impairment 
existed. 

ADS applied the qualitative assessment to specific trademarks for the annual impairment tests performed as of 
March 31, 2019 and 2018. For the current year test, ADS assessed various assumptions, events and 
circumstances that would have affected the estimated fair value of the reporting unit as compared to its March 
31, 2016 quantitative fair value measurement. The results of this assessment indicated that it is not more likely 
than not that the trademarks fair value is less than the reporting unit carrying value. The Company did not 
incur any impairment charges for Intangible assets in the fiscal years ended March 31, 2019, 2018, and 2017.

Other Assets - Other assets include investments in unconsolidated affiliates accounted for under the equity 
method, capitalized software development costs, including cloud computing costs, deposits, central parts, and 
other miscellaneous assets. In the fiscal year ended March 31, 2018, the Company discontinued offering the 
cash surrender value of officer life insurance and collected proceeds of $13.6 million from the sale of the 
officer life insurance. The Company capitalizes development costs for internal use software. Capitalization of 
software development costs begins in the application development stage and ends when the asset is placed into 
service. The Company amortizes such costs using the straight-line method over estimated useful lives of 2 to 
10 years, which is included in General and administrative expense, Selling expense or Cost of goods sold 
within the Consolidated Statements of Operations depending on the nature of the asset and its intended use. 
Central parts represent spare production equipment items which are used to replace worn or broken production 
equipment parts and help reduce the risk of prolonged equipment outages. The cost of central parts is 
amortized on a straight-line basis over estimated useful lives of 5 to 10 years. 

The Company evaluates its investments in unconsolidated affiliates for impairment whenever events or 
changes in circumstances indicate that the carrying amount might not be recoverable and recognizes an 
impairment loss when a decline in value below carrying value is determined to be other-than-temporary. 
Under these circumstances, the Company would adjust the investment down to its estimated fair value, which 
then becomes its new carrying value. For the fiscal year ended March 31, 2017, the Company recorded an 
impairment charge of $1.3 million related to its investment in the South American Joint Venture. The 
impairment charge is included in Equity in net loss of unconsolidated affiliates in the Consolidated Statements 
of Operations. See “Note 11. Investment in Unconsolidated Affiliates.”

Advanced Drainage Systems, Inc. 

Leases - Leases are reviewed for capital or operating classification at their inception. The Company uses the 
lower of the rate implicit in the lease or its incremental borrowing rate in the assessment of lease classification 
and assumes the initial lease term includes cancellable and renewal periods that are reasonably assured. For 
leases classified as capital leases at lease inception, the Company records a capital lease asset and lease 
financing obligation equal to the lesser of the present value of the minimum lease payments or the fair market 
value of the leased asset. The capital lease asset is recorded in Property, plant and equipment, net and 
amortized to its expected residual value at the end of the lease term using the straight-line method, and the 
lease financing obligation is amortized using the effective interest method over the lease term with the rental 
payments being allocated to principal and interest. For leases classified as operating leases, the Company 
records rent expense over the useful life using the straight-line method. 

Foreign Currency Translation - Assets and liabilities of foreign subsidiaries with a functional currency other 
than the U.S. dollar are translated into U.S. dollars at the current rate of exchange on the last day of the 
reporting period. Revenues and expenses are translated at a monthly average exchange rate and equity 
transactions are translated using either the actual exchange rate on the day of the transaction or a monthly 
average historical exchange rate. The South American Joint Venture operates within Argentina, which on July 
1, 2018, was identified for high inflationary accounting. The Company has determined the effect of a change 
in the exchange rate under high inflationary accounting is not expected to have a material effect on the 
Company’s results in any annual period. For the fiscal years ended March 31, 2019 and 2018, the Company’s 
Accumulated other comprehensive loss (“AOCL”) consisted of foreign currency translation gains and losses. 

Net Sales - The Company generates revenue by selling pipe and related water management products primarily 
to distributors, retailers, buying groups and co-operative buying groups. Products are shipped predominately 
by the Company’s internal fleet, and the Company does not provide any additional revenue generating 
services after product delivery. Payment terms and conditions vary by contract.  

Revenue is recognized at the point in-time obligations under the terms of a contract with a customer are 
satisfied, which generally occurs upon the transfer of control of the promised goods. In substantially all of the 
Company’s contracts with customers, control is transferred to the customer upon delivery. The Company 
recognizes revenue in an amount that reflects the consideration the Company expects to be entitled to in 
exchange for those goods or services.  

Shipping Costs - The Company incurs shipping costs to deliver products to customers using an in-house fleet 
or common carrier. Typically shipping costs are prepaid and included in the product price; however, in some 
instances, the Company bills shipping costs to customers. Shipping costs are also incurred to physically move 
raw materials, tooling and products between manufacturing and distribution facilities. Shipping costs to 
deliver products to customers for the fiscal years ended March 31, 2019, 2018, and 2017 were $131.3 million, 
$120.7 million, and $110.5 million, respectively, and are included in Cost of goods sold. Shipping costs billed 
to customers were $7.7 million, $6.3 million, and $5.5 million during 2019, 2018 and 2017, respectively, and 
are included in Net sales. 

Stock-Based Compensation - See “Note 17. Stock-Based Compensation” for information about our stock-
based compensation award programs and related accounting policies. 

Advertising - The Company expenses advertising costs as incurred. Advertising costs are recorded in Selling 
expenses in the Consolidated Statements of Operations. The total advertising costs were $3.8 million, $4.1 
million, and $3.1 million for the fiscal years ended March 31, 2019, 2018, and 2017, respectively. 

Self-Insurance - The Company is self-insured for short term disability and medical coverage it provides for 
substantially all eligible employees. The Company is self-insured for medical claims up to the individual and 
aggregate stop-loss coverage limits. The Company accrues for claims incurred but not reported based on an 
estimate of future claims related to events that occurred prior to the fiscal year end if it has not met the 
aggregate stop-loss coverage limit. Amounts expensed totaled $42.4 million, $41.3 million, and $39.5 million 
for the fiscal years ended March 31, 2019, 2018, and 2017, respectively, of which employees contributed $6.7 
million, $5.9 million, and $5.1 million, respectively. 

F-18

ADS is also self-insured for various other general insurance programs to the extent of the applicable 
deductible limits on the Company’s insurance coverage. These programs include primarily automobile, 
general liability and employment practices coverage with a deductible of $0.5 million per occurrence or claim 
incurred. Amounts expensed during the period, including an estimate for claims incurred but not reported at 
year end, were $2.3 million, $2.2 million, and $1.8 million, for the years ended March 31, 2019, 2018, and 
2017, respectively. 

ADS is also self-insured for workers’ compensation insurance with stop-loss coverage for claims that exceed 
$0.3 million per incident up to the respective state statutory limits. Amounts expensed, including an estimate 
for claims incurred but not reported, were $2.8 million, $1.3 million, and $2.1 million for the fiscal years 
ended March 31, 2019, 2018, and 2017, respectively. 

Income Taxes - Income taxes are accounted for under the asset and liability method. Deferred tax assets and 
liabilities are recognized and represent the future tax consequences attributable to differences between the 
financial statement carrying amounts of existing assets and liabilities and their respective tax bases. They are 
measured using the enacted tax rates expected to apply to taxable income in the years in which the related 
temporary differences are expected to be recovered or settled. Valuation allowances are established against 
deferred tax assets when it is more likely than not that the realization of those deferred tax assets will not 
occur. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the 
period that includes the enactment date. The deferred income tax provision represents the change during the 
reporting period in the deferred tax assets and deferred tax liabilities. Penalties and interest recorded on 
income taxes payable are recorded as part of Income tax expense. 

The Company determines whether an uncertain tax position is more likely than not to be sustained upon 
examination, including resolution of any related appeals or litigation process, based upon the technical merits 
of the position. For tax positions meeting the more likely than not threshold, the tax amount recognized in the 
financial statements is the largest amount of tax benefit that has a greater than 50% likelihood of being 
realized upon ultimate settlement with the relevant taxing authority. 

Fair Values - The fair value framework requires the categorization of assets and liabilities into three levels 
based upon assumptions (inputs) used to price the assets or liabilities. Level 1 provides the most reliable 
measure of fair value, whereas Level 3 generally requires significant management judgment. 

ADS’s policy for determining when transfers between levels have occurred is to use the actual date of the 
event or change in circumstances that caused the transfer. 

Concentrations of Risk - The Company has a large, active customer base of approximately twenty thousand 
customers with two customers, Ferguson Enterprises and Core and Main, each representing more than 10% of 
annual net sales. Such customers accounted for 25.4%, 25.4%, and 23.5% of fiscal 2019, 2018 and 2017 net 
sales, respectively. The Company’s customer base is diversified across the range of end markets that it serves. 

Financial instruments that potentially subject the Company to a concentration of credit risk consist principally 
of Receivables. The Company provides its products to customers based on an evaluation of the customers’ 
financial condition, generally without requiring collateral. Exposure to losses on Receivables is principally 
dependent on each customer’s financial condition. The Company performs ongoing credit evaluations of its 
customers. The Company monitors the exposure for credit losses and maintains allowances for anticipated 
losses. Concentrations of credit risk with respect to Receivables are limited due to the large number of 
customers comprising the Company’s customer base and their dispersion across many different geographies. 
One customer, Ferguson Enterprises, accounted for approximately 19.1% and 17.6% of Receivables at 
March 31, 2019 and 2018, respectively. 

F-19

Advanced Drainage Systems, Inc. 

Derivatives - The Company recognizes derivative instruments as either assets or liabilities and measure those 
instruments at fair value. ADS uses interest rate swaps, commodity options in the form of collars and swaps, 
and foreign currency forward contracts to manage various exposures to interest rate, commodity price, and 
exchange rate fluctuations. These instruments do not qualify for hedge accounting treatment. For the interest 
rate swap executed on June 28, 2017, gains and losses resulting from the difference between the spot rate and 
applicable base rate is recorded in Interest expense. For commodity options in the form of collars and swaps, 
and foreign currency forward contracts, gains and losses from contract settlements and changes in fair value of 
the derivative instruments are recognized in Derivative losses (gains) and other expense (income), net in the 
Consolidated Statements of Operations. The Company’s policy is to present all derivative balances on a gross 
basis. 

The Company also has forward purchase agreements in place with certain resin suppliers for virgin 
polyethylene resin. The agreements specify a fixed amount of virgin resin material to be purchased at a fixed 
price for a given period of time in quantities the Company will use in the normal course of business, and 
therefore, qualify as normal purchase contracts. The cost of such resin is recognized in Cost of goods sold in 
the Consolidated Statements of Operations. 

Recent Accounting Pronouncements 

Recently Adopted Accounting Guidance  

Cloud Computing - On August 29, 2018, the Financial Accounting Standards Board (the “FASB”) issued an 
accounting standard update (“ASU”) to provide guidance on implementation costs incurred in a cloud 
computing arrangement (“CCA”) that is a service contract. The ASU, which was released in response to a 
consensus reached by the Emerging Issues Task Force at its June 2018 meeting, aligns the accounting for such 
costs with the guidance on capitalizing costs associated with developing or obtaining internal-use software. 
Specifically, the ASU includes in its scope implementation costs of a CCA that is a service contract and 
clarifies that a customer should apply CCA guidance to determine which implementation costs should be 
capitalized in such a CCA. The Company adopted this update effective July 1, 2018 on a prospective basis. 
The new standard did not have a material impact on the Consolidated Financial Statements. 

Revenue Recognition - In May 2014, the FASB issued an ASU which amends the guidance for revenue 
recognition. This amendment contains principles that will require an entity to recognize revenue to depict the 
transfer of goods and services to customers at an amount that an entity expects to be entitled to in exchange 
for goods or services. The amendment sets forth a new revenue recognition model that requires identifying the 
contract, identifying the performance obligations and recognizing the revenue upon satisfaction of 
performance obligations. In August 2015, the FASB issued an additional ASU that deferred the effective date 
of the new revenue standard for public entities to periods beginning after December 15, 2017, with early 
adoption permitted but not earlier than the original effective date of periods beginning after December 15, 
2016. There have also been various additional ASUs issued by the FASB in 2016 that further amend this new 
revenue standard. The updated standard permits the use of either the retrospective or cumulative effect 
transition method. The Company adopted these standards on April 1, 2018 using the modified retrospective 
transition method. See “Note 3. Revenue Recognition” for further information on the adoption of the revenue 
recognition ASUs. 

Cash Flow Classification - In August 2016, the FASB issued an ASU which provides amended guidance on 
the classification of certain cash receipts and cash payments in the statement of cash flows, including related 
to debt prepayment or debt extinguishment costs, contingent consideration payments made after a business 
combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-
owned life insurance and distributions received from equity method investees. This update is effective for 
fiscal years beginning after December 15, 2017, including interim periods within those years, and early 
adoption is permitted. This amended guidance must be applied retrospectively to all periods presented but may 
be applied prospectively if retrospective application would be impracticable. The Company adopted this 
update effective April 1, 2018 using the retrospective method. The new standard did not have an impact on the 
Consolidated Financial Statements.

Goodwill Impairment - In January 2017, the FASB issued an ASU which removes the requirement to compare 
the implied fair value of goodwill with its carrying amount as part of step 2 of the goodwill impairment test. 
As a result, under the standards update, an entity should perform its annual, or interim, goodwill impairment 
test by comparing the fair value of a reporting unit with its carrying amount and should recognize an 
impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; 
however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. 
The amendments are effective for annual periods beginning after December 15, 2019. Early adoption is 
permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. 
The Company adopted this update effective April 1, 2018. The new standard did not have an impact on the 
Consolidated Financial Statements. 

Definition of a Business - In January 2017, the FASB issued an ASU to clarify the definition of a business. 
The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill, and 
consolidation. The amendments are intended to help companies and other organizations evaluate whether 
transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments 
provide a more robust framework to use in determining when a set of assets and activities is a business. The 
amendments are effective for annual periods beginning after December 15, 2017, including interim periods 
within those periods. The Company adopted this update effective April 1, 2018. The new standard did not 
have an impact on the Consolidated Financial Statements. 

Stock-Based Compensation - In May 2017, the FASB issued an ASU to clarify when modification accounting 
should be applied for changes to the terms or conditions of share-based payment awards. The amendments 
clarify that modification accounting guidance should only be applied if there is a change to the value, vesting 
conditions, or award classification and would not be required if the changes are considered non-substantive. 
The amendments are effective for annual periods beginning after December 15, 2017, including interim 
periods within those periods. The Company adopted this update effective April 1, 2018. The new standard did 
not have an impact on the Consolidated Financial Statements. 

Fair Value Measurement – In August 2018, the FASB issued an ASU that was intended to improve the 
effectiveness of disclosures in notes to financial statements. The standard removed, modified and added 
certain disclosure requirements related to fair value measurements. This standard was effective for fiscal years 
beginning after December 15, 2019. The standard required the use of the retrospective transition method for 
specific amendments within the ASU and the prospective treatment of other amendments. Early adoption was 
permitted. The Company early adopted this ASU, effective for the Company’s Annual Report on Form 10-K 
for the year ending March 31, 2019. The Company applied the new standard to “Note 9. Fair Value 
Measurement” in the notes to the Consolidated Financial Statements. 

Recent Accounting Guidance Not Yet Adopted  

Leases - In February 2016, the FASB issued Accounting Standard Codification (“ASC”) 842, Leases, which 
amends the guidance for leases. This standard contains principles that will require an entity to recognize most 
leases on the balance sheet by recording a right-of-use asset and a lease liability, unless the lease is a short-
term lease that has an accounting lease term of twelve months or less. The standard also contains other 
changes to the current lease guidance that may result in changes to how entities determine which contractual 
arrangements qualify as a lease, the accounting for executory costs, such as property taxes and insurance, as 
well as which lease origination costs will be capitalizable. This standard is effective for fiscal years beginning 
after December 15, 2018, including interim periods within those years. Early adoption of this standard is 
permitted. The standard allows the use of the modified retrospective transition method, whereby the new 
guidance will be applied at the beginning of the earliest period presented in the financial statements of the 
period of adoption. The modified retrospective transition approach includes certain practical expedients that 
entities may elect to apply in transition. In July 2018, the FASB amended ASC 842 to provide another 
transition method, allowing a cumulative effect adjustment to the opening balance of retained earnings during 
the period of adoption. The Company has implemented a new software solution to improve the process of 
tracking and accounting for leases under the current and new standards. The Company will adopt this standard 
effective April 1, 2019 using the modified retrospective transition method which does not require adjustments 

F-21 

 
Table of Contents 

Advanced Drainage Systems, Inc. 

to comparative periods or require modified disclosures for those periods. The Company has elected the 
transition relief practical expedients. The transition relief practical expedient package permits the Company to 
not reassess (1) whether any expired or existing contracts are or contain a lease, (2) the lease classification for 
any expired or existing lease or (3) initial direct costs for any existing lease. The Company is continuing to 
finalize new processes and internal controls required to comply with the new lease standard. The adoption of 
ASC 842 will not have a material impact on the Statement of Operations or Statement of Cash Flows. The 
accounting for capital leases will remain substantially unchanged. The recording of right-of-use assets and 
lease liabilities is expected to have a material impact on the Company’s Consolidated Balance Sheet. 

Measurement of Credit Losses - In June 2016, the FASB issued an ASU which provides amended guidance on 
the measurement of credit losses on financial instruments, including trade receivables. This standard requires 
the use of an impairment model referred to as the current expected credit loss model. This standard is effective 
for fiscal years beginning after December 15, 2019, including interim periods within those years, and early 
adoption is permitted for fiscal years beginning after December 15, 2018. The Company expects to adopt this 
standard effective April 1, 2020. The Company is currently evaluating the impact of this standard on the 
Consolidated Financial Statements. 

Hedge Accounting – In August 2017, the FASB issued an ASU which expands an entity’s ability to apply 
hedge accounting for non-financial and financial risk components and provides a simplified approach for fair 
value hedging of interest rate risk. The standard also refines how entities assess hedge effectiveness. This 
standard is effective for fiscal years beginning after December 15, 2018, including interim periods within 
those years, and early adoption is permitted. The Company will adopt this standard effective April 1, 2019. 
The new standard did not have an impact on the Consolidated Financial Statements. 

Except for the pronouncements described above, there have been no new accounting pronouncements issued 
or adopted since the filing of the fiscal 2018 Form 10-K that have significance, or potential significance, to the 
Consolidated Financial Statements.  

2. 

LOSS ON DISPOSAL OF ASSETS AND COSTS FROM EXIT AND DISPOSAL ACTIVITIES 

In fiscal 2018, the Company initiated restructuring activities (the “2018 Restructuring Plan”), which 
continued throughout fiscal 2019, including closing underutilized manufacturing facilities, reducing 
headcount, optimizing product offerings and eliminating nonessential costs, designed to improve the 
Company’s cost structure. The Company closed one and four manufacturing facilities in the fiscal years 
ended March 31, 2019 and 2018, respectively. As additional restructuring opportunities may be identified, the 
Company does not have an estimated completion date or expected total cost estimate for the 2018 
Restructuring Plan.  

In fiscal year ended March 31, 2017, the Company recorded expenses related to three manufacturing facilities 
that were closed during fiscal 2017 of approximately $3.5 million. In addition, the Company accelerated 
depreciation of specifically identified obsolete assets of approximately $3.0 million and recorded $2.0 million 
of disposals and partial disposals of fixed assets. The following table summarizes the activity included in 
Loss on disposal of assets and costs from exit and disposal activities recorded during the fiscal years ended 
March 31, 2019, 2018, and 2017:

activities recorded in Other liabilities in the Consolidated Balance Sheet as of March 31, 2019 and March 31, 
2018, respectively. 

Periodically, the Company will dispose of equipment, including equipment accounted for as capital leases. 
The net loss on the disposition of the equipment was $2.0 million, $3.6 million, and $8.5 million during fiscal 
2019, 2018 and 2017, respectively. 

3. 

REVENUE RECOGNITION 

On April 1, 2018, the Company adopted ASC 606, Revenue from Contracts with Customers (“ASC 606”), and 
all related amendments using the modified retrospective transition method. The adoption of ASC 606 did not 
impact the opening retained earnings balance or cause a material shift in the amount or timing of revenue 
recognition. Results for reporting periods beginning after April 1, 2018 are presented under ASC 606, while 
prior period amounts were not adjusted and continue to be reported in a consistent manner with historical 
accounting policies. 

The Company generates revenue by selling pipe and related water management products primarily to 
distributors, retailers, buying groups and co-operative buying groups. Products are shipped predominately by 
the Company’s internal fleet, and the Company does not provide any additional revenue generating services 
after product delivery. Payment terms and conditions vary by contract.  

Revenue is recognized at the point in-time obligations under the terms of a contract with a customer are 
satisfied, which generally occurs upon the transfer of control of the promised goods. In substantially all of the 
Company’s contracts with customers, control is transferred to the customer upon delivery. The Company 
recognizes revenue in an amount that reflects the consideration the Company expects to be entitled to in 
exchange for those goods or services. Revenue is presented in the Consolidated Statements of Operations net

of allowances for returns, rebates, discounts, and taxes collected concurrently with revenue-producing 
activities. 

Refer to “Note 21. Business Segments Information” for the Company’s disaggregation of Net sales by 
reportable segment. The disclosure of Net sales by reportable segment is aligned by geographical region and 
product type and best depicts how the nature, amount, timing and uncertainty of revenue and cash flows are 
affected by economic factors. 

Significant Judgments - The Company’s performance obligation under contracts with customers is to sell 
and deliver pipe and related water management products. The Company’s contracts with customers may 
contain multiple performance obligations by promising to deliver multiple products to the customer. For these 
contracts, the Company accounts for individual performance obligations separately if they are distinct. The 
transaction price is allocated to the separate performance obligations on a relative standalone selling price 
basis. 

The Company’s products are generally sold with a right of return, and the Company may provide credits or 
incentives, which are accounted for as variable consideration when estimating the amount of revenue to 
recognize. Variable consideration is estimated at contract inception and updated at the end of each reporting 
period as additional information becomes available and only to the extent that it is probable that a significant 
reversal of any incremental revenue will not occur. 

Contract Balances - The Company recognizes a contract asset representing the Company’s right to recover 
products upon the receipt of returned products and a contract liability for the customer refund. The adoption of 
this standard resulted in the Company recording a contract asset for estimated inventory returns. On April 1, 
2018, the estimated inventory returns resulted in a $0.6 million decrease in Receivables, net and a $0.6 million 
increase in Other current assets on the Company’s Consolidated Balance Sheets. The following table presents 
the balance of the Company’s contract asset and liability as of March 31, 2019 and April 1, 2018:

Practical Expedients and Exemptions - The Company expenses incremental costs to obtain a contract (e.g. 
sales commissions) when incurred as the amortization period would have been one year or less. These costs 
are recorded within selling expenses on the Consolidated Statements of Operations. 

The Company elected the accounting policy election permitted by ASC 606 to account for shipping and 
handling costs as activities to fulfill the promise to transfer the goods when these activities are performed after 
a customer obtains control of the goods. Revenue is recognized at the point of shipment. 

The Company elected the accounting policy to exclude from the transaction price all sales taxes that are 
assessed by a governmental authority and that are imposed on and concurrent with a specific revenue-
producing transaction and collected by the Company from a customer, for example, sales, use, value added, 
and some excise taxes. 

Further, the Company does not disclose the value of unsatisfied performance obligations for contracts with an 
original expected length of one year or less.

ACQUISITIONS 

Fiscal 2019 Acquisition of Noncontrolling interest in BaySaver 

BaySaver Technologies LLC (“BaySaver”) was a joint venture that was established to produce and distribute 
water quality filters and separators used in the removal of sediment and pollution from storm water. During 
the third quarter of fiscal 2019, ADS purchased the remaining 35% ownership interest in BaySaver for a 
purchase price of $8.8 million. The purchase of the remaining 35% ownership interest was reflected as a 
reduction in the Redeemable noncontrolling interest in subsidiary in the Consolidated Balance Sheets and as a 
financing activity in the Consolidated Statement of Cash Flows. Additionally, resulting from this transaction, 
the Company recorded a $0.6 million non-cash adjustment to deferred taxes. BaySaver is now a wholly-owned 
subsidiary of ADS.  

Fiscal 2018 Acquisition of DURASLOT, Inc. 

On August 1, 2017, ADS acquired DURASLOT, Inc., a manufacturer of linear surface drains, for $2.3 
million. The acquisition included approximately $2.1 million of tax-deductible goodwill. 

Fiscal 2017 Acquisition of Plastic Tubing Industries 

On February 6, 2017, ADS acquired Plastic Tubing Industries (“PTI”), a manufacturer of HDPE pipe and 
related accessories. With the acquisition, ADS increased its manufacturing footprint in Georgia and Texas, 
while adding production capacity to the existing ADS manufacturing facilities in Florida, to better serve 
growing demand in the region. The purchase price of PTI was $9.5 million, financed through the existing line 
of credit facility. At the time of acquisition, $8.5 million was paid in cash; the remaining $1.0 million was 
paid on August 6, 2018. The results of operations of PTI are included in the Consolidated Statements of 
Operations after February 6, 2017. The Net sales and Income before income taxes of PTI since the acquisition 
date included in the Consolidated Statements of Operations for the fiscal year ended March 31, 2017 were 
immaterial. 

The fair value of the net assets acquired exceeded the purchase price. The difference was recognized as a gain 
on bargain purchase in fiscal 2017. The purchase price allocation is as follows:

 (a)  Amount necessary to reduce minimum lease payments to present value calculated at the lower of the rate 

implicit in the lease or the Company’s incremental borrowing rate at lease inception. 

Certain leases contain residual value guarantees that create a contingent obligation on the part of the Company 
to compensate the lessor if the leased asset cannot be sold for an amount in excess of a specified minimum 
value at the conclusion of the lease term. The calculation is based on the original cost of the transportation 
equipment, less lease payments made, compared to a percentage of the transportation equipment’s fair market 
value at the time of sale. All leased units covered by this guarantee have been classified as capital leases and a 
corresponding capital lease obligation was recorded. Therefore, no further contingent obligation is needed. 

Operating leases - The Company leases certain real estate and office equipment under various cancellable and 
non-cancellable operating lease agreements that expire at various dates through fiscal year 2037.  

Future minimum rental commitments under non-cancellable operating leases as of March 31, 2019, are

FAIR VALUE MEASUREMENT 

When applying fair value principles in the valuation of assets and liabilities, the Company is required to 
maximize the use of quoted market prices and minimize the use of unobservable inputs. The Company has not 
changed its valuation techniques used in measuring the fair value of any financial assets or liabilities during 
the fiscal years presented. The fair value estimates take into consideration the credit risk of both the Company 
and its counterparties. 

When active market quotes are not available for financial assets and liabilities, ADS uses industry standard 
valuation models. Where applicable, these models project future cash flows and discount the future amounts to 
a present value using market-based observable inputs including credit risk, interest rate curves, foreign 
currency rates and forward and spot prices for currencies. In circumstances where market-based observable 
inputs are not available, management judgment is used to develop assumptions to estimate fair value. 
Generally, the fair value of our Level 3 instruments is estimated as the net present value of expected future 
cash flows based on internal and external inputs. 

Recurring Fair Value Measurements

There were no transfers in or out of Level 3 for the fiscal years ended March 31, 2019 and 2018. 

Valuation of Contingent Consideration for Acquisitions - The method used to price these liabilities is 
considered Level 3, due to the subjective nature of the unobservable inputs used to determine the fair value. 

Valuation of Debt - The carrying amounts of current financial assets and liabilities approximate fair value 
because of the immediate or short-term maturity of these items, or in the case of derivative instruments, 
because they are recorded at fair value. The carrying and fair value of the Company’s Senior Notes (discussed 
in “Note 13. Debt”) were $100.0 million and $98.9 million, respectively, as of March 31, 2019 and $125.0 
million and $122.3 million, respectively, at March 31, 2018. The fair value of the Senior Notes was 
determined based on a comparison of the interest rate and terms of such borrowings to the rates and terms of 
similar debt available for the period. The Company believes the carrying amount on the remaining long-term 
debt, including the Secured Bank Loans, is not materially different from its fair value as the interest rates and 
terms of the borrowings are similar to currently available borrowings. The categorization of the framework 
used to evaluate this debt is considered Level 2.

Non-recurring Fair Value Measurements 

Valuation of Investment in the South American Joint Venture - During the fourth quarter of the fiscal year 
ended March 31, 2017, the Company recorded a $1.3 million impairment charge related to its investment in 
the South American Joint Venture equal to the difference between the fair value of the investment and the 
carrying value. The method used to value the investment is considered Level 3 due to the subjective nature of 
the unobservable inputs used to determine the fair value. Significant unobservable inputs included the WACC 
used to discount the future cash flows, which were between 9.3% and 16.5%, based on the markets in which 
the South American Joint Venture conducts business. See “Note 11. Investment in Unconsolidated Affiliates.”

INVESTMENT IN UNCONSOLIDATED AFFILIATES 

The Company participates in an unconsolidated joint venture, South American Joint Venture, which is 50% 
owned by the Company’s wholly-owned subsidiary ADS Chile. Prior to April 2018, The Company 
participated in an unconsolidated joint venture, Tigre-ADS USA, Inc. (“Tigre-ADS USA”), which was 49% 
owned by the Company’s wholly-owned subsidiary ADS Ventures, Inc.  

South American Joint Venture - The Company’s investment in this unconsolidated joint venture was formed 
for the purpose of expanding upon the growth of manufacturing and selling HDPE corrugated pipe in the 
South American market via the joint venture partner’s local presence and expertise throughout the region. The 
Company has concluded that it is appropriate to account for this investment using the equity method, whereby 
the Company’s share of the income or loss of the joint venture is reported in the Consolidated Statements of 
Operations under Equity in net loss (income) of unconsolidated affiliates and the Company’s investment in the 
joint venture is included in Other assets in the Consolidated Balance Sheets. The Company is not required to 
consolidate the South American Joint Venture as it is not the primary beneficiary, although the Company does 
hold significant variable interests in the South American Joint Venture through the equity investment and debt 
guarantee. 

Summarized financial data as of the fiscal years ended March 31 for the South American Joint Venture is as 
follows:

In order to improve the South American Joint Venture’s working capital position and allow it to reallocate 
capital resources to business growth, the Company and the joint venture partner each contributed equal 
amounts of outstanding receivables owed to them from the South American Joint Venture in exchange for 
incremental ownership interest in the South American Joint Venture in December 2017. The Company and the 
joint venture partner continue to maintain a 50% ownership interest in the South American Joint Venture 
following the contribution. As a result of the transaction the Company contributed receivables of 
approximately $5.8 million net of a $3.0 million allowance for doubtful accounts and recorded an additional 
investment in the South American Joint Venture at the fair value of $4.7 million and a $1.9 million gain on the 
book value of the receivables. The investment is recorded within Other assets on the Company’s Consolidated 
Balance Sheets and the gain is recorded within Equity in net (income) loss of unconsolidated affiliates on the 
Company’s Consolidated Statements of Operations. 

During the fourth quarter of the fiscal year ended March 31, 2017, the Company determined there was an 
other-than-temporary decline in the fair value of its investment in the South American Joint Venture, resulting 
from a further decline of unfavorable regional economic conditions. Accordingly, the Company recorded an 
impairment charges of $1.3 million, reducing the carrying value of the investment to its fair value. Past

impairment charges have resulted in a basis difference between the cost of the investment and the amount of 
underlying equity in net assets of the South American Joint Venture of $4.0 million and $4.4 million as of 
March 31, 2019 and 2018 respectively. The basis difference will be amortized over the estimated remaining 
useful life of the underlying property, plant and equipment, 8 years. The Company recognized $0.4 million, 
$0.5 million and $0.4 million of amortization of the basis difference in fiscal 2019, 2018 and 2017, 
respectively. The impairment charge is included in Equity in net loss of unconsolidated affiliates in the 
Consolidated Statements of Operations. 

Tigre-ADS USA - The former joint venture was established to manufacture and sell PVC fittings for 
waterworks, plumbing, and HVAC applications primarily in the United States and Canadian markets. The joint 
venture represented a continuation of the activities of Tigre-ADS USA through its Janesville, Wisconsin 
manufacturing facility. The Company was not required to consolidate Tigre-ADS USA as it was not the 
primary beneficiary, although the Company did hold a significant variable interest in Tigre-ADS USA through 
the equity investment. 

In April 2018, the Company and the joint venture partner agreed to exchange the Company’s shares of Tigre-
ADS USA for a release from the existing debt guarantees. Following the exchange, the Company no longer 
has an interest in Tigre-ADS USA. As a result of the agreement, the Company determined there was an other-
than-temporary decline in the fair value of its investment in Tigre-ADS USA. Accordingly, the Company 
recorded an impairment charge of $0.3 million, reducing the carrying value of the investment to its fair value. 
The impairment charge is included in Equity in net loss of unconsolidated affiliates in the Consolidated 
Statements of Operations. 

12.     RELATED PARTY TRANSACTIONS 

ADS Mexicana - ADS conducts business in Mexico and Central America through its joint venture ADS 
Mexicana. ADS Mexicana’s Revolving Credit Facility expired on June 22, 2018 and was replaced by an 
Intercompany Revolving Credit Promissory Note (the “Intercompany Note”) with a borrowing capacity of 
$12.0 million. The Intercompany Note matures on June 22, 2022. The other joint venture partner indemnifies 
the Company for 49% of any unpaid borrowing. The interest rates under the Intercompany Note are 
determined by certain base rates or London Interbank Offered Rate (“LIBOR”) plus an applicable margin 
based on the Leverage Ratio. As of March 31, 2019, there were no borrowings under the Intercompany Note. 

South American Joint Venture - The Company’s South American Joint Venture manufactures and sells 
HDPE corrugated pipe in the South American market. ADS is the guarantor for 50% of the South American 
Joint Venture’s credit facility, and the debt guarantee is shared equally with the joint venture partner. The 
maximum potential obligation under this guarantee totals $11.0 million as of March 31, 2019. The maximum 
borrowing permitted under the South American Joint Venture’s credit facility is $22.0 million. This credit 
facility allows borrowings in either Chilean pesos or US dollars at a fixed interest rate determined at inception 
of each draw on the facility. The guarantee of the South American Joint Venture’s debt expires on 
December 31, 2020. ADS does not anticipate any required contributions related to the balance of this credit 
facility. As of March 31, 2019 and 2018, the outstanding principal balance of the credit facility including 
letters of credit was $12.3 million and $14.5 million, respectively. As of March 31, 2019, there were no U.S. 
dollar denominated loans. The weighted average interest rate as of March 31, 2019 was 5.57% on Chilean 
peso denominated loans. 

ADS and the South American Joint Venture have entered into shared services arrangements in order to 
execute the joint venture services. Occasionally, the South American Joint Venture enters into agreements for 
pipe sales with ADS and its other related parties, which were $1.3 million and $2.1 million in the fiscal years 
ended March 31, 2019 and 2018, respectively. ADS pipe sales to the South American Joint Venture were $1.2 
million and $0.4 million in the fiscal years ended March 31, 2019 and 2018, respectively. 

BaySaver - BaySaver Technologies LLC (“BaySaver”) was a joint venture that was established to produce 
and distribute water quality filters and separators used in the removal of sediment and pollution from storm 
water. During the third quarter, ADS purchased the remaining 35% ownership interest in BaySaver for a 
purchase price of $8.8 million. The purchase of the remaining 35% ownership interest was reflected as a 

F-33 

 
Table of Contents

reduction in the Redeemable noncontrolling interest in subsidiary in the Consolidated Balance Sheets and as a 
financing activity in the Consolidated Statement of Cash Flows. Additionally, resulting from this transaction, 
the Company recorded a non-cash adjustment to deferred taxes. BaySaver is now a wholly-owned subsidiary 
of ADS. 

Tigre-ADS USA - Tigre-ADS USA was a joint venture established to manufacture and sell PVC fittings for 
waterworks, plumbing, and HVAC applications primarily in the United States and Canadian markets. ADS 
owned 49% of the outstanding shares of capital stock of Tigre-ADS USA. The joint venture represented a 
continuation of the existing activities of Tigre-ADS USA through its Janesville, Wisconsin manufacturing 
facility. In April 2018, the Company and the joint venture partner agreed to exchange the Company’s shares of 
Tigre-ADS USA for a release from the existing debt guarantees. Following the exchange, the Company no 
longer has an interest in Tigre-ADS USA. Following the exchange of Tigre-ADS USA shares, the Company 
still considers Tigre-ADS USA a related party as a result of the Company’s joint venture in the South 
American Joint Venture discussed above. 

ADS purchased $0.3 million, $2.0 million and $1.6 million of Tigre-ADS USA manufactured products for use 
in the production of ADS products during fiscal years 2019, 2018 and 2017, respectively.

Secured Bank Loans - On June 22, 2017, the Company and certain of its subsidiaries, as guarantors 
(collectively, the “Guarantors”), entered into a Second Amended and Restated Credit Agreement (the “Credit 
Agreement”) with PNC Bank, National Association (“PNC”), as administrative agent (in such capacity, the 
“Agent”), and various financial institutions party thereto (together with PNC, collectively, the “Lenders”), 
pursuant to which the Lenders have committed to provide the Company a $550.0 million revolving credit 
facility (with an option to increase such revolving credit facility or incur new term loans in an agreement 
amount of up to $150.0 million) subject to the terms and conditions in the Credit Agreement. The Credit 
Agreement amends and restates the Amended and Restated Credit Agreement dated as of June 12, 2013, as 
amended, among the Company and certain of its subsidiaries, as guarantors, various financial institutions 
party thereto, and the Agent. The Secured Bank Loans are secured by a lien on a significant majority of the 
Company’s assets. Letters of credit outstanding at March 31, 2019 amounted to $8.5 million and reduce the 
availability of the Revolving Credit Facilities. The amount available for borrowing for the Company was 
$407.1 million at March 31, 2019. 

Borrowings under the credit facility will be used for general corporate purposes, including repurchases of 
stock, repayments of existing indebtedness, repayments of short-term borrowings, working capital 
requirements, capital expenditures and acquisitions. The interest rates under the Credit Agreement are 
determined by certain base rates or LIBOR rates, plus an applicable margin based on the Leverage Ratio then

in effect. The average interest rate was 3.69% as of March 31, 2019. The Credit Agreement has an expiration 
date of June 22, 2022. 

The Credit Agreement sets forth certain customary business and financial covenants to which the Company 
and Guarantors are subject when any amounts under the Credit Agreement are outstanding, including 
covenants that limit or restrict the ability of the Company and the Guarantors to incur indebtedness, to make 
capital distributions, and to incur certain liens and encumbrances on any of its respective property. The two 
primary financial covenants of the Credit Agreement require the Company to maintain a certain Leverage 
Ratio and an Interest Coverage Ratio. 

The Credit Agreement Leverage Ratio generally requires that at the end of any fiscal quarter, for the four 
fiscal quarters then ended, the Company will not permit the ratio of its total consolidated indebtedness to the 
Company’s Consolidated EBITDA (as defined in the Credit Agreement) to be greater than 4.00 to 1.00 (or 
4.25 to 1.00 as of the date of any acquisitions permitted under the Credit Agreement for which the aggregate 
consideration is $100.0 million or greater). The Credit Agreement Interest Coverage Ratio generally requires 
that at the end of any fiscal quarter, for the four fiscal quarters then ended, the Company will not permit the 
ratio of Consolidated EBITDA to the Company’s consolidated interest expense payable during such period to 
be less than 3.00 to 1.00. 

The Credit Agreement provides for customary events of default, including, among other things, in the event of 
nonpayment of principal, interest, or other amounts, a representation or warranty proving to have been 
incorrect in any material respect when made, failure to perform or observe certain covenants within a specified 
period of time, a cross-default to other Company indebtedness of a specified amount, the bankruptcy or 
insolvency of the Company or a Guarantor, monetary judgment defaults of a specified amount, a change of 
control of the Company, and ERISA defaults resulting in liability under certain circumstances. In the event of 
a default by the Company, the Agent or the requisite number of Lenders may declare all amounts owed under 
the Credit Agreement and outstanding letters of credit immediately due and payable and terminate the 
Lenders’ commitments to make loans under the Credit Agreement. For defaults related to bankruptcy, 
insolvency or reorganization proceedings, the commitments of the Lenders will be automatically terminated 
and all outstanding loans and other amounts will become immediately due and payable.  

On June 28, 2017, ADS executed a Forward Interest Rate Swap on the 30-Day LIBOR interest rate to mitigate 
the impact of interest rate volatility. The swap has a notional value of $100.0 million and a fixed rate of 
1.8195% for a five year period. 

Senior Notes - On June 22, 2017, the Company and the Guarantors entered into the Second Amended and 
Restated Private Shelf Agreement (the “Private Shelf Agreement”) with PGIM, Inc. (“Prudential”) and certain 
other parties thereto. The Private Shelf Agreement amends and restates the Amended and Restated Private 
Shelf Agreement dated as of September 24, 2010, as amended, pursuant to which the Company has previously 
issued and sold secured senior notes of the Company. Under the terms of the Private Shelf Agreement, the 
Company may request that Prudential purchase, over the next three years, secured senior notes of the 
Company so long as the aggregate principal amount of notes outstanding at any time does not exceed $175.0 
million (the “Shelf Notes”). The Shelf Notes shall bear interest at a fixed interest rate and have a maturity date 
not to exceed ten years from the date of issuance. Prudential and its affiliates are under no obligation to 
purchase any of the Shelf Notes. The interest rate and terms of payment of any series of Shelf Notes will be 
determined at the time of purchase. The proceeds of any series of Shelf Notes will be used as specified in the 
request for purchase with respect to such series, subject to compliance with the requirements in the Private 
Shelf Agreement, but are anticipated to be used for general corporate purposes, including refinancing of short-
term borrowings and/or repayment of outstanding indebtedness under the Credit Agreement, which is 
described above, as well as financing of capital expenditures and acquisitions.   

Obligations under the Private Shelf Agreement are secured by capital stock of certain direct and indirect 
subsidiaries of the Company and the Guarantors and substantially all other tangible and intangible personal 
property owned by the Company and the Guarantors. Obligations under the Private Shelf Agreement are 
secured by the collateral on a pari passu basis with obligations under the Credit Agreement.

The Private Shelf Agreement sets forth certain customary business and financial covenants to which the 
Company and Guarantors are subject when any Shelf Note is outstanding, including covenants that limit or 
restrict the ability of the Company and the Guarantors to incur indebtedness, to make capital distributions, and 
to incur certain liens and encumbrances on any of its respective property. The two primary financial covenants 
of the Private Shelf Agreement require the Company to maintain a certain Leverage Ratio and an Interest 
Coverage Ratio. 

The Private Self Agreement Leverage Ratio generally requires that at the end of any fiscal quarter, for the four 
fiscal quarters then ended, the Company will not permit the ratio of its total consolidated indebtedness to the 
Company’s Consolidated EBITDA (as defined in the Private Shelf Agreement) to be greater than 4.00 to 1.00 
(or 4.25 to 1.00 as of the date of any acquisitions permitted under the Private Self Agreement for which the 
aggregate consideration is $100.0 million or greater). The Private Self Agreement Interest Coverage Ratio 
generally requires that at the end of any fiscal quarter, for the four fiscal quarters then ended, the Company 
will not permit the ratio of Consolidated EBITDA to the Company’s consolidated interest expense payable 
during such period to be less than 3.00 to 1.00. 

The Private Shelf Agreement provides for customary events of default, including, among other things, in the 
event of nonpayment of principal, interest, or other amounts, a representation or warranty proving to have 
been incorrect in any material respect when made, failure to perform or observe certain covenants within a 
specified period of time, a cross-default to other Company indebtedness of a specified amount, the bankruptcy 
or insolvency of the Company or a Guarantor, monetary judgment defaults of a specified amount, a change of 
control of the Company, and ERISA defaults resulting in liability under certain circumstances. In the event of 
a default by the Company, any or all holders of Shelf Notes may declare amounts owed under the Private 
Shelf Agreement immediately due and payable. For defaults related to bankruptcy, insolvency or 
reorganization proceedings, all amounts owed under the Agreement will become immediately due and 
payable, and Prudential may at its option terminate the Private Shelf Note Facility.  

On June 28, 2017, the Company issued and sold Shelf Notes in the aggregate principal amount of $75.0 
million pursuant to the Private Shelf Agreement. The $75.0 million of Shelf Notes bears interest at a fixed 
interest rate of 3.53% per annum and have a maturity date of seven years from the date of issuance. The rate is 
subject to an additional 100 basis point excess leverage fee if the calculated leverage ratio exceeds 3 to 1 at the 
end of a fiscal quarter. On July 9, 2018, the Company amended the Second Amended and Restated Credit 
Agreement (the “Credit Agreement”) and the Second Amended and Restated Private Shelf Agreement (the 
“Private Shelf Agreement”) to amend the definition of Consolidated EBITDA and changed the timing of the 
quarterly rate adjustments. In addition, the amendment to the Credit Agreement clarified the process of a 
transition to replace LIBOR which is being phased out. 

Master Loan and Security Agreement – In June 2016, ADS signed a Master Loan and Security Agreement 
for Equipment Financing in the U.S. and Canada for an aggregate amount of up to $4.5 million. During fiscal 
2017, the Company issued $4.6 million of Equipment Notes with a weighted average fixed interest rate at 
2.72%, with the aggregate loan amount during fiscal 2017 reaching a total of $4.2 million, net of principal 
payments. Each Equipment Note amortizes the principal over five years and is payable monthly. The average 
interest rate was 2.74% as of March 31, 2019 

Secured Bank Loans – Prior to the long-term debt modification in June 2017, the Company had a revolving 
credit facility with borrowing capacity of $325.0 million for ADS, Inc., a Revolving Credit Facility for ADS 
Mexicana with borrowing capacity of $12.0 million and a $100.0 million term note. The Company did not 
modify ADS Mexicana’s borrowing capacity. The ADSM Mexicana revolving credit facility matured on June 
22, 2018. There were no borrowings under the Revolving Credit Facility – ADS Mexicana. Refer to “Note 12. 
Related Party Transactions” for additional information on the Intercompany Note which replaced the 
Revolving Credit Facility – ADS Mexicana. The average rate was 2.61% at March 31, 2017.  

Senior Notes Payable – Prior to the long-term debt modification in June 2017, the Company had an 
agreement with Prudential Investment Management, Inc. for the issuance of senior promissory notes (“Senior 
Notes”), for an aggregate amount of up to $100.0 million. During fiscal 2010, the Company issued $75.0 
million of Senior Notes with interest fixed at 5.6% and payable quarterly. The rate was subject to an additional 

F-36 

 
Table of Contents 

Advanced Drainage Systems, Inc. 

200 basis point excess leverage fee if the calculated leverage ratio exceeds 3 to 1 at the end of a fiscal quarter. 
In July 2013, ADS issued an additional $25.0 million of Senior Notes. Interest for the additional $25.0 million 
is payable quarterly and is fixed at 4.05%. A principal payment of $25.0 million was made in fiscal 2017, 
fiscal 2018 and fiscal 2019. Principal payment of $25.0 million will be made in fiscal 2020. 

Industrial Revenue Bonds - Between 1996 and 2007, ADS issued industrial revenue bonds for the 
construction of four production facilities. Two of the bonds were retired during fiscal 2011 and one of the 
bonds was retired in fiscal 2015. The final bond matured in February 2019, leaving the Company with no 
current Industrial Revenue Bonds. The Company made principal payments of $0.9 million, $1.9 million and 
$0.9 million in fiscal year ended March 31, 2019, 2018 and 2017, respectively.     

ADS Mexicana Scotia Bank Revolving Credit Facility - On December 11, 2014, ADS’s joint venture, ADS 
Mexicana, entered into a credit agreement with Scotia Bank. The credit agreement provides for revolving 
loans up to a maximum aggregate principal amount of $5.0 million. The proceeds of the revolving credit 
facility have primarily been used for short term investments and are available for working capital needs. The 
interest rates of the revolving credit facilities are determined by LIBOR rates, Tasa de Interes Interbancaria de 
Equilibrio (TIIE) or the Costos de Captacion rates, plus an applicable margin. On May 27, 2016, ADS 
Mexicana obtained a waiver on a covenant from Scotia Bank relating to ADS Mexicana failing to notify 
Scotia Bank of changes in legal organizational structure and payment of dividends. The Scotia Bank revolving 
credit facility matured on December 11, 2017. The obligations under the revolving credit facility were not 
guaranteed by ADS. As of the maturity date, there was no outstanding principal drawn on the Scotia Bank 
revolving credit facility, which bore interest at the LIBOR, plus 1.60%.

The Company uses interest rate swaps and commodity options in the form of collars and swaps to manage its 
various exposures to interest rate and commodity price fluctuations. For the interest rate swap executed on 
June 28, 2017, gains and losses resulting from the difference between the spot rate and applicable base rate is 
recorded in Interest expense. For collars and commodity swaps, contract settlement gains and losses are 
recorded in the Consolidated Statements of Operations in Derivative gains and other income, net. Gains and 
losses related to mark-to-market adjustments for changes in fair value of the derivative contracts are also 
recorded in the Consolidated Statements of Operations in Derivative gains and other income, net.

The Company secures supplies of resin raw material by agreeing to purchase quantities during a future given 
period at a fixed price. These purchase contracts typically range from 1 to 12 months and occur in the ordinary 
course of business. Under such purchase contracts in place at March 31, 2019, the Company has agreed to 
purchase resin over the period April 2019 through December 2019 at a committed purchase cost of $17.6 
million. 

Litigation and Other Proceedings 

As previously disclosed in the Company’s fiscal 2018 Form 10-K, the Company’s historical accounting 
practices were the subject of an investigation by SEC’s Division of Enforcement (the “Enforcement 
Division”), which began in August 2015. That matter was resolved on July 10, 2018 via a settlement between 
the Company and the SEC. Pursuant to the settlement, the Company consented to the entry of an 
administrative order without admitting or denying the findings therein. The order required the Company to 
cease and desist from committing or causing any violations and any future violations of certain provisions of 
the federal securities laws and the rules promulgated thereunder and to pay a civil monetary penalty of $1.0 
million, which payment has been made. The Company previously accrued an expense for the penalty amount 
during fiscal 2018. 

On July 29, 2015, a putative stockholder class action, Christopher Wyche, individually and on behalf of all 
others similarly situated v. Advanced Drainage Systems, Inc., et al. (Case No. 1:15-cv-05955-KPF), was 
commenced in the U.S. District Court for the Southern District of New York (the “District Court”), naming 
the Company, along with Joseph A. Chlapaty, the Company’s former Chief Executive Officer, and Mark B. 
Sturgeon, the Company’s former Chief Financial Officer, as defendants and alleging violations of the federal 
securities laws. An amended complaint was filed on April 28, 2016. The amended complaint alleged that the 
Company made material misrepresentations and/or omissions of material fact in its public disclosures during 
the period from July 25, 2014 through March 29, 2016, in violation of Sections 10(b) and 20(a) of the 
Securities Exchange Act of 1934, as amended, and Rule 10b-5 promulgated thereunder. On March 10, 2017, 
the District Court dismissed plaintiff’s claims against all defendants in their entirety and with prejudice. 
Plaintiff appealed to the United States Court of Appeals for the Second Circuit, and on October 13, 2017 the 
District Court’s judgment was affirmed by the Second Circuit. On October 27, 2017, plaintiff filed a petition 
for rehearing with the Second Circuit. The Second Circuit denied the petition for rehearing on November 28, 
2017. On November 27, 2018, the plaintiff filed a motion for relief from final judgment and for leave to file an 
amended complaint with the District Court. The defendants have opposed the plaintiff’s motion and are

awaiting a decision by the District Court. While it is reasonably possible that this matter ultimately could be 
decided unfavorably to the Company, the Company is currently unable to estimate the range of the possible 
losses, but it could be material. 

The Company is involved from time to time in various legal proceedings that arise in the ordinary course of 
business, including but not limited to commercial disputes, environmental matters, employee related claims, 
intellectual property disputes and litigation in connection with transactions including acquisitions and 
divestitures. The Company does not believe that such litigation, claims, and administrative proceedings will 
have a material adverse impact on the Company’s financial position or results of operations. The Company 
records a liability when a loss is considered probable, and the amount can be reasonably estimated. 

Other Commitments and Contingencies 

In March 2019, the Company initiated an internal investigation process, under the guidelines of the 
Company’s Code of Business Conduct and Ethics, into its consolidated joint venture affiliate ADS 
Mexicana’s senior management’s ethical and business conduct, as well as compliance of certain products 
with, along with considerations into Mexican laws and regulations over the last 12 months. The Company has 
concluded that the current estimate of probable losses resulting from the investigation is not material to our 
consolidated financial statements, however due to the inherent uncertainties in determining the use, 
installation application and location of our ADS Mexicana products sold, along with the consideration of 
Mexican laws and regulations related to warranty and product liability obligations, the Company is unable to 
determine the maximum potential future losses that may occur, which could be material to the consolidated 
financial statements. 

16.  EMPLOYEE BENEFIT PLANS 

Employee Stock Ownership Plan (“ESOP”) - The Company established the Advanced Drainage 
Systems, Inc. ESOP (the “ESOP” or the “Plan”) effective April 1, 1993. The Plan was funded through a 
transfer of assets from our tax-qualified profit-sharing retirement plan, as well as a 30-year term loan from 
ADS. Within 30 days following the repayment of the ESOP loan, which will occur no later than March 2023, 
the ESOP committee can direct the shares of redeemable convertible preferred stock owned by the ESOP to be 
converted into shares of the Company’s common stock. The Plan operates as a tax-qualified leveraged ESOP 
and was designed to enable eligible employees to acquire stock ownership interest in ADS. Employees of 
ADS who have reached the age of 18 are generally eligible to participate in the Plan on March 31 after 
six months of service. Upon retirement, disability, death, or vested terminations, (i) a participant or designated 
beneficiary may elect to receive the amount in their account attributable to the 1993 transfer of assets from our 
tax-qualified profit sharing retirement plan in the form of cash or ADS stock with any fractional shares paid in 
cash; (ii) stock credited to the participants’ ESOP stock account resulting from the ESOP’s loan repayments 
are distributed in the form of ADS stock, and (iii) amounts credited to the participants’ ESOP cash account are 
distributed in the form of cash. Upon attainment of age 50 and seven years of participation in the Plan, a 
participant may elect to diversify specified percentages of the number of shares of ADS stock credited to the 
participant’s ESOP stock account in compliance with applicable law. 

The Company is obligated to make contributions to the Plan, which, when aggregated with the Plan’s 
dividends on the Plan’s unallocated shares of redeemable convertible preferred stock, equal the amount 
necessary to enable the Plan to make its regularly scheduled payments of principal and interest due on its term 
loan to ADS. As the Plan makes annual payments of principal and interest, an appropriate percentage of 
preferred stock is allocated to ESOP participants’ accounts in accordance with plan terms that are compliant 
with applicable Internal Revenue Code and regulatory provisions. 

The carrying value of redeemable convertible preferred stock held by the ESOP trust, but not yet earned by the 
ESOP participants or used for dividends, is reported as Deferred compensation — unearned ESOP shares 
within the Mezzanine equity section of our Consolidated Balance Sheets. 

Compensation expense and related dividends paid with ESOP shares for services rendered throughout the 
period are recognized based upon the annual fair value of the shares allocated. Deferred compensation — 

F-39 

 
Table of Contents 

Advanced Drainage Systems, Inc. 

unearned ESOP shares is relieved at fair value, with any difference between the annual fair value and the 
carrying value of shares when allocated being added to Additional paid in capital. The fair value of the shares 
allocated was $19.90, $20.00, and $16.80 per share of redeemable convertible preferred stock at March 31, 
2019, 2018, and 2017, respectively, resulting in an average annual fair value per share of $19.95, $18.40, and 
$16.58 per share for the fiscal years ended March 31, 2019, 2018, and 2017, respectively. During the fiscal 
years ended March 31, 2019, 2018, and 2017, the Company recognized compensation expense of $15.3 
million, $11.7 million, and $9.6 million, respectively, related to allocation of ESOP shares to participants. 

Required dividends on allocated shares are generally passed through and paid in cash to the participants and 
required dividends on unallocated shares are paid in cash to the Plan and generally used to service the Plan’s 
debt. 

The ESOP committee directed the Plan trustee to retain dividends on unallocated ADS shares rather than to 
service the Plan’s debt. In the fiscal years ended March 31, 2019, 2018, and 2017, the Company recognized 
compensation expense and the trustee retained $3.3 million, $3.2 million and $2.9 million, respectively, for 
dividends on unallocated ADS shares. These dividends were allocated to participants based on the total shares 
in their account in relation to total shares allocated at March 31, 2019 and 2018. 

Redeemable Convertible Preferred Stock - The Trustee of the Company’s ESOP has the ability to put shares 
of the redeemable convertible preferred stock to the Company absent a market for the Company’s common 
stock, and as a result the redeemable convertible preferred stock is classified as Mezzanine equity in the 
Company’s Consolidated Balance Sheets. The put option requirements of the Internal Revenue Code apply in 
the event that the Company’s common stock is not a registration type class of security or its trading has been 
restricted. Therefore, the holders of Redeemable convertible preferred stock have a put right to require the 
Company to repurchase such shares in the event that the common stock is not listed for trading or otherwise 
quoted on the NYSE, AMEX, NASDAQ, or any other market more senior than the OTC Bulletin Board. As of 
March 31, 2019, the applicable redemption value was $0.7818 per share as there were no unpaid cumulative 
dividends. 

Given that the event that may trigger redemption of the Redeemable convertible preferred stock (the listing or 
quotation on a market more senior than the OTC Bulletin Board) is not solely within the Company’s control, 
the redeemable convertible preferred stock is presented in the mezzanine equity section of the Consolidated 
Balance Sheets. As of March 31, 2019, the Company did not adjust the carrying value of the redeemable 
convertible preferred stock to its redemption value or recognize any changes in fair value as the Company did 
not consider it probable that the Redeemable convertible preferred stock would become redeemable. 

The Redeemable convertible preferred stock has a required cumulative 2.5% dividend (based on the 
liquidation value of $0.7818 per share) and is convertible at a rate of 0.7692 shares of common stock for each 
share of Redeemable convertible preferred stock. The 2.5% annual dividend is payable in cash or additional

Executive Retirement Expense - ADS has employment agreements with certain executives that include 
potential payments to be made to those executives upon termination. The terms of the termination payments 
vary by executive, but are generally based on current base salary and bonus levels at the time of termination. 
The contractual termination payments vest upon either (1) certain contingent occurrences terminating 
employment such as death, disability, layoff, the executive voluntarily quitting due to a breach of covenants 
by the Company or for other “good reason” or (2) the executive reaching a specified retirement age while still 
working for the Company, as defined in the individual employee agreement. 

The Company accrues a liability from the effective date of the executive’s employment agreement to the date 
the executive reaches the required retirement age while working for the Company, which is considered the 
service period for this obligation. The liability is estimated based on each executive’s current base salary and 
bonus levels. Because the executives vest in the termination payments equally over the relevant service period, 
the Company recognizes the related compensation expense based on the straight-line method over the service 
period. If an executive terminates their employment prior to reaching the required retirement age, no payment 
is required and the previously recorded compensation expense for that executive is reversed and recorded as a 
benefit to compensation expense in the period the executive terminates employment. 

The compensation (benefit) expense recorded related to the executive termination payments for the fiscal 
years ended March 31, 2019, 2018, and 2017 was $(0.2) million, $1.5 million and $1.1 million, respectively, 
and is included in General and administrative expenses in the Consolidated Statements of Operations. As of 
March 31, 2019 and 2018, the executive termination payment obligation was $4.3 million and $6.1 million, 
respectively, and is included in Other accrued liabilities and Other liabilities in the Consolidated Balance 
Sheets. 

Profit-Sharing Plan - The Company has a tax-qualified profit-sharing retirement plan with a 401(k) feature 
covering substantially all U.S. eligible employees. The Company did not make employer contributions to this 
plan in the fiscal years ended March 31, 2019, 2018, and 2017. The Company has a defined contribution 
postretirement benefit plan covering Canadian employees. The Company recognized costs of $0.4 million, 
$0.7 million and $0.8 million in the fiscal years ended March 31, 2019, 2018, and 2017. 

17.  STOCK-BASED COMPENSATION 

The Company has several programs for stock-based payments to employees and directors, including stock 
options and restricted stock. Stock-based compensation expense is recorded in General and administrative 
expenses, Selling expenses and Cost of goods sold in the Consolidated Statements of Operations.

On April 1, 2017, the Company modified all outstanding awards to remove the provision that permitted 
employees to satisfy their personal tax liability with the net settlement of shares in excess of minimum tax 
withholding. Employees can now withhold shares with a fair value up to the maximum statutory rate. 
Accordingly, the Company modified the awards previously accounted for as liability-classified to equity-
classified and reclassified the carrying amount of the awards of $13.7 million to Paid-in capital in the 
Consolidated Balance Sheet. All stock options have been accounted for as equity-classified awards for the 
periods subsequent to the modification. Prior to the modification, liability-classified awards were reclassified 
to additional paid in capital at fair value when stock options were exercised. 

The following table summarizes the assumptions used in estimating the fair value of stock options:

Equity classified stock option awards are measured based on the grant date estimated fair value of each award. 
Compensation expense for stock options is recognized on a straight-line basis over the employee’s requisite 
service period, which is generally the vesting period of the grant. The Company estimates the fair value of 
stock options using a Black-Scholes option-pricing model.     

2000 Plan - The Company’s 2000 stock option plan (“2000 Plan”) provided for the issuance of statutory and 
non-statutory stock options to management based upon the discretion of the Board of Directors. The plan 
generally provided for grants with the exercise price equal to fair value on the date of grant, which vest in 
three equal annual amounts beginning in year five and expire after approximately 10 years from issuance. The 
Company had no shares available for grant under the 2000 Plan as of March 31, 2019.

The Tax Cuts and Jobs Act (the “Tax Act”) was enacted on December 22, 2017. The Tax Act significantly 
revises the future ongoing U.S. corporate income tax by, among other things, lowering the U.S. corporate 
income tax rate from 35% to 21%, full expensing on qualified property, eliminates the domestic 
manufacturing deduction and implements a territorial tax system. The 21% U.S. corporate income tax rate 
was effective January 1, 2018. Based on the Company’s fiscal year end of March 31, the U.S. statutory 
federal rate is 31.5% for the fiscal year ended March 31, 2018. 

The Company previously recognized the provisional tax impacts related to revaluation of deferred tax assets 
and liabilities and deemed repatriated earnings and included these amounts in its financial statements for the 
year ended March 31, 2018. During the year ended March 31, 2019, the Company finalized the accounting 
for the Tax Act. During the year ended March 31, 2019, the Company did not make any material adjustments 
to its provisional amounts included in its consolidated financial statements for the year ended March 31, 
2018. 

The Company recognized a provisional amount for revaluing its deferred tax attributes resulting in a $16.0 
million tax benefit that was recorded for the fiscal year ended March 31, 2018. On the basis of revised 
computations in filing the U.S. federal tax return during the third quarter, the Company recognized an 
additional measurement-period adjustment of $0.4 million to deferred tax expense for the year ended March

31, 2019. A total deferred tax benefit of $15.6 million was recorded. The Company’s accounting for its 
deferred tax attributes is now complete. 

The Company had $26.5 million of undistributed earnings on its foreign subsidiaries subject to the deemed 
mandatory repatriation. The Company recognized a provisional amount of $5.2 million of income tax 
expense that was recorded for the fiscal year ended March 31, 2018. After the utilization of existing foreign 
tax credits, the Company expected to pay additional U.S. federal taxes of approximately $1.0 million as of the 
fiscal year ended March 31, 2018. On the basis of revised computations in filing the U.S. federal tax return 
during the third quarter, the Company recognized an additional measurement-period adjustment of $0.6 
million to income tax benefit for the year ended March 31, 2019. A total transition tax expense of $4.6 
million was recorded. After the utilization of existing foreign tax credits, the Company paid an additional 
U.S. federal taxes of $0.7 million. The Company’s accounting for the deemed mandatory repatriation tax is 
now complete. 

These undistributed earnings are intended to be reinvested indefinitely with the exception of cash dividends 
paid by our ADS Mexicana joint venture. It is not practicable to estimate the amount of U.S. tax, which 
would primarily relate to withholding tax, that might be payable on the eventual remittance of such earnings.

deferred tax liabilities at March 31 were comprised of:

Accounting for Uncertain Tax Positions 

As of March 31, 2019, The Company had unrecognized tax benefit of $5.7 million, which if resolved 
favorably, would reduce income tax expense by $5.7 million. A reconciliation of the beginning and ending 
amounts of unrecognized tax benefits for the years ended March 31, 2019, 2018, and 2017 is as follows:

The short-term portion of the unrecognized tax benefit of $2.6 million at March 31, 2019 is recorded in Other 
Accrued liabilities on the Company’s Consolidated Balance Sheet. The long-term portion of unrecognized tax 
benefits are recorded in Other liabilities in the Company’s Consolidated Balance Sheets. These amounts 
include potential accrued interest and penalties of $1.5 million and $2.1 million at March 31, 2019 and 2018, 
respectively. 

The Company believes that over the next twelve months, it is reasonably possible that up to $2.6 million of 
unrecognized tax benefits could be resolved as the result of settlements of audits and the expiration of statutes 
of limitation. Final settlement of these issues may result in payments that are more or less than this amount, 
but the Company does not anticipate that the resolution of these matters will result in a material change to its 
consolidated financial position or results of operations. 

The Company is currently open to audit under the statute of limitations by the IRS for the fiscal years ended 
March 31, 2016 through March 31, 2019. The majority of the Company’s state income tax returns are open to 
audit under the statute of limitations for the years ended March 31, 2015 through March 31, 2019. The foreign 
income tax returns are open to audit under the statute of limitations for the years ended March 31, 2015 
through March 31, 2019. 

19.  NET INCOME PER SHARE AND STOCKHOLDERS’ EQUITY 

Basic net income per share is calculated by dividing the Net income available to common stockholders by the 
weighted-average number of common shares outstanding during the period, without consideration for 
common stock equivalents. Diluted net income per share is computed by dividing the Net income available to 
common stockholders by the weighted-average number of common stock equivalents outstanding for the 
period. 

Holders of certain unvested restricted stock have non-forfeitable rights to dividends when declared on 
common stock, and holders of redeemable convertible preferred stock participate in dividends on an as-
converted basis when declared on common stock. As a result, unvested restricted stock and redeemable 
convertible preferred stock meet the definition of participating securities, which requires us to apply the two-
class method to compute both basic and diluted net income per share. The two-class method is an earnings 
allocation formula that treats participating securities as having rights to earnings that would otherwise have 
been available to common stockholders. 

The dilutive effect of stock options and unvested restricted stock is based on the more dilutive of the treasury 
stock method or the diluted two-class method. In computing diluted net income per share, income available to 
common stockholders used in the basic net income per share calculation (numerator) is adjusted, subject to 
sequencing rules, for certain adjustments that would result from the assumed issuance of potential common 
shares. After the effective date of the IPO, management’s intent is to share settle; therefore, these shares are 
included in the calculation from July 26, 2014 through March 31, 2019, if dilutive. For purposes of the

calculation of diluted net income per share, stock options and unvested restricted stock are considered to be 
potential common stock and are only included in the calculations when their effect is dilutive. 

The Company’s redeemable common stock is included in the weighted-average number of common shares 
outstanding for calculating basic and diluted net income per share. 

The following table presents information necessary to calculate net income per share for the fiscal years ended 
March 31, 2019, 2018, and 2017, as well as potentially dilutive securities excluded from the weighted average 
number of diluted common shares outstanding because their inclusion would have been anti-dilutive:

Stockholders’ Equity – During the fiscal year ended March 31, 2018, the Company repurchased 0.4 million 
shares of common stock at a cost of $7.9 million. The repurchases were made under the Board of Directors’ 
authorization in February 2017 to repurchase up to $50 million of ADS common stock in accordance with 
applicable securities laws. As of March 31, 2019, approximately $42.1 million of common stock may be 
repurchased under the authorization. The repurchase program does not obligate the Company to acquire any 
particular amount of common stock, and may be suspended or terminated at any time at the Company’s 
discretion.   

Treasury Stock Retirement – On November 1, 2017, the Board of Directors resolved to retire 97.7 million 
shares of Treasury Stock. The retirement of the Treasury Stock resulted in a reclassification of Treasury stock 
to Paid-In-Capital and did not have an impact on Total Stockholders’ Equity.

21.  BUSINESS SEGMENT INFORMATION 

ADS operates its business in two distinct operating and reportable segments based on the markets it serves: 
“Domestic” and “International.” The Chief Operating Decision Maker (“CODM”) evaluates segment 
reporting based on Net sales and Segment Adjusted EBITDA. The Company calculates Segment Adjusted 
EBITDA as net income or loss before interest, income taxes, depreciation and amortization, stock-based 
compensation expense, non-cash charges and certain other expenses. Beginning April 1, 2018, the Company 
revised its allocation of allowances for returns, rebates, and discounts between Pipe and Allied Products for 
segment reporting purposes. Prior to April 1, 2018, the Company allocated substantially all returns, rebates, 
and discounts to Pipe net sales. These changes did not impact the Company’s previously reported consolidated 
financial results. The prior period segment results and related disclosures have been recast to conform to the 
current year presentation under the new allocation methodology. 

Domestic 

The Company’s Domestic segment manufactures and markets products throughout the United States. The 
Company maintains and serves these markets through product distribution relationships with many of the 
largest national and independent waterworks distributors, major national retailers as well as an extensive 
network of hundreds of small to medium-sized distributors across the U.S. The Company also sells through a 
broad variety of buying groups and co-ops in the United States. Products include single wall pipe, N-12 HDPE 
pipe sold into the Storm sewer and Infrastructure markets, High Performance PP pipe sold into the Storm 
sewer and sanitary sewer markets, and our broad line of Allied Products including StormTech, Nyloplast, 
ARC Septic Chambers, Inserta Tee, BaySaver filters and water quality structures, Fittings, and FleXstorm. 
The Company’s Domestic segment sales are diversified across all regions of the country. 

International 

The Company’s International segment manufactures and markets products in certain regions outside of the 
United States, with a growth strategy focused on Company owned facilities in Canada, subsidiaries that 
distribute to Europe and the Middle East, exports and through the Company’s joint-ventures with local 

F-51

partners in Mexico and South America. The Company’s joint venture strategy provides it with local and 
regional access to new markets such as Brazil, Chile, Argentina, Peru and Colombia. The Company’s Mexican 
joint venture, ADS Mexicana, primarily serves the Mexican and Central American markets, while its South 
American Joint Venture, Tigre-ADS, is the primary channel to serve the South American markets. The 
Company’s International product line includes single wall pipe, N-12 HDPE pipe, and High Performance PP 
pipe. The Canadian market also sells our broad line of Allied Products, while sales in Latin America are 
currently concentrated in fittings and Nyloplast.

24.  SUBSEQUENT EVENTS 

Dividends on Common Stock - During the first quarter of fiscal 2020, the Company declared a quarterly cash 
dividend of $0.09 per share of common stock. The dividend is payable on June 14, 2019 to stockholders of 
record at the close of business on June 3, 2019. 

Special Dividend – During the first quarter of fiscal 2020, the Board of Directors approved a special dividend 
of $1.00 per share payable on June 14, 2019 to stockholder of record at the close of business on June 3, 2019. 
The dividend will be used to pay back a portion of the ESOP loan resulting in approximately 12 million shares 
of redeemable convertible preferred stock being allocated to ESOP participants. Assuming a preferred share 
fair value of $21.20, the Company will recognize approximately $245 million in additional stock-based 
compensation expense. The stock-based compensation expense recognized will vary due to fluctuations in the 
Company’s stock price through June 30, 2019. This additional expense will be recognized in Cost of goods 
sold, Selling expenses and General and administrative expenses on the Company’s Consolidated Statement of 
Operations in the first quarter of fiscal 2020. 

Directors Not Standing for Re-Election - On May 22, 2019, Richard A. Rosenthal and Abigail S. Wexner 
notified the Board of Directors of the Company of their respective decisions not to stand for re-election as 
directors of the Company at the Company’s 2019 Annual Meeting of Stockholders. The decision by each of 
Mr. Rosenthal and Ms. Wexner not to stand for re-election was not a result of any disagreement with the 
Company or the Board of Directors.
