|  OUR COMPANY and STRATEGY  |

Impax Laboratories, Inc. (NASDAQ: IPXL) is an integrated specialty pharmaceutical company 
focused on developing, manufacturing and marketing generic and brand pharmaceutical products. 
We operate two divisions, referred to as Impax Generics and Impax Specialty Pharma. 

The Impax Generics division concentrates on developing, manufacturing, selling and distributing 
complex solid dose and alternative dosage form products. The Generics portfolio covers a 
broad range of therapeutic areas with products that have technically challenging drug-delivery 
mechanisms or unique development formulations. We plan to continue to expand our portfolio 
by primarily targeting high revenue potential products, including products with the potential to be 
first-to-file or first-to-market, providing certain competitive advantages. We are also pursuing external 
acquisition and partnership opportunities that further expand our solid oral and alternative dosage form 
product portfolio and development capabilities.

The Impax Specialty Pharma division is primarily focused on the development and promotion 
through our specialty sales force of proprietary branded pharmaceutical products for the treatment 
of central nervous system (CNS) disorders and other specialty segments.  We believe that we 
have the research, development and formulation expertise to develop branded products that will 
deliver significant improvements over existing therapies. We plan to continue investing in our 
development pipeline, both internally and through acquisitions and partnerships primarily focused 
on late-stage and next generation product opportunities.

We CARE
to make
a difference

Impax is always striving to fine-tune all aspects of our business in order to remain a vital 
contributor in our industry. We are transforming our culture to continually focus on quality and 
drive ongoing improvement to deliver sustainable results for our patients, customers, healthcare 
providers, regulators and stockholders, without compromise or exceptions.

We are committed to making a difference by developing and investing in our employees in order to 
retain and attract top talent and nurture employee growth that will support the long-term success 
of the company.

We are committed to making a difference in the communities where we live and work. Our 
employees are devoted to creating positive change, and as a global organization with a diverse 
workforce, we encourage our employees to demonstrate our core values by investing their time 
where they can make a difference.

|  OUR COMPANY and STRATEGY  |

|  TO OUR FELLOW STOCKHOLDERS  |

2015 was an eventful year for Impax - one in which we made great progress on our 
strategic priorities and accomplished our key objectives and milestones that were 
established by our Board of Directors. We showed our commitment to the vision of 
building a specialty pharmaceutical company which enhances the lives of patients 
and provides challenging, rewarding opportunities for employees, in order to set the 
foundation for creating long-term value for our customers and stockholders.  

The quality initiatives implemented across the Company were a critical contributor to 
our success in 2015 and will remain the cornerstone for all we do moving forward. 
We also leveraged our core competencies by identifying complementary business 
opportunities to develop and market generic and branded pharmaceutical products. 

In our Generics business, we currently have more than 60 commercialized products 
and over 40 Abbreviated New Drug Applications (ANDAs) in regulatory review or 
in development. The generic portfolio focuses on a range of therapeutic areas, 
including products that have technically challenging drug-delivery mechanisms or 
unique product formulations. 

Our Specialty Pharma business concentrates primarily on developing and 
commercializing proprietary branded pharmaceuticals products for the treatment 
of Central Nervous System (CNS) disorders, including migraine and Parkinson’s 
disease. The specialty portfolio is currently comprised of six commercialized 
products, one in regulatory review and one in development. 

2015 Financial Performance

Our dual platform strategy generated positive results in our 2015 financial 
performance, with Impax achieving double-digit top and bottom line growth. Total 
revenues grew to $860 million, a 44% increase over last year. This growth was 
driven by the approval and successful launch of Rytary® (Carbidopa and Levodopa) 
Extended-Release capsules, 14 generic product launches, the expansion of several 
key generic products, such as diclofenac sodium gel and the addition of product 
revenues from our Tower Holdings (Tower)* acquisition. On an adjusted basis 
(non-GAAP), earnings per diluted share increased 10% to $1.45. On a GAAP basis, 
earnings per diluted share decreased to $0.54. We ended the year with $340 million 
in cash and no outstanding senior secured debt.

*  Impax acquired Tower Holdings, Inc. (including operating subsidiaries CorePharma LLC and 
  Amedra Pharmaceuticals LLC) and Lineage Therapeutics Inc. on March 9, 2015.

2015 Highlights

We delivered these financial results while expanding our 
business, successfully integrating the products we aquired 
from the Tower acquisition and positioning for continued 
investment in quality operations and R&D. 

Our strategies and actions are organized around four 
strategic pillars: (1) Focus on Quality and Operations, 
(2) Maximize Dual Platform, (3) Optimize R&D and (4) 
Business Development Acceleration. A key accomplishment 
in 2015 was the positive resolution of the FDA’s warning 
letter at our Hayward, California manufacturing facility and 
subsequent generic product approvals from that facility. We 
continue to focus on quality initiatives while advancing our 
commitment to creating a world-class manufacturing and 
operating program.

Another key highlight for the year was the growth of our 
Specialty Pharma business and its return to profitability 
during the year. This was led by the approval and launch of 
our first internally developed drug, Rytary. During 2015, we 
generated steady month-to-month growth in prescriptions 
and market share that tracked to plan. The Specialty 
Pharma business also benefited from the addition of 
products in a new therapeutic category that were acquired 
in the Tower acquisition.

We are proud of our many other achievements in 2015, 
which are highlighted in the chart by strategic pillar.   

Focus in 2016

By successfully delivering on multiple objectives in 2015, 
we believe we are well positioned for further organic 
growth in 2016. 

From a financial perspective, we are targeting another year 
of double-digit revenue and adjusted EPS growth, while 
continuing to invest in global quality and compliance systems, 
R&D and our Specialty Pharma sales force. We believe we 
are well-positioned with significant financial resources and 
balance sheet flexibility to support internal investments as 
well as external growth opportunities.

Overview

PART I.

We are a specialty pharmaceutical  company applying formulation and development  expertise, as well as our drug delivery  technology, to the development,  manufacture  and
marketing of bioequivalent pharmaceutical products, commonly referred to as “generics,” in addition to the development and marketing of branded products. We operate in two segments,
referred  to  as  “Impax  Generics”  and  “Impax  Specialty  Pharma”.  The  Impax  Generics  division  concentrates  its  efforts  on  the  development,  manufacture,  sale  and  distribution  of  our
generic products, which are the pharmaceutical  and therapeutic  equivalents of brand-name drug products and are usually marketed  under their established nonproprietary  drug names
rather than by a brand name. The Impax Specialty Pharma division is engaged in the development of proprietary brand pharmaceutical products that we believe represent improvements
to  already-approved  pharmaceutical  products  addressing  the  treatment  of  central  nervous  system  (“CNS”)  disorders.  The  Impax  Specialty  Pharma  division  is  also  engaged  in  the
promotion, sale and distribution of several branded products, including our internally developed branded pharmaceutical product, Rytary®, an extended release oral capsule formulation
of  carbidopa-levodopa  for  the  treatment  of  Parkinson’s  disease  (“PD”),  post-encephalitic  parkinsonism,  and  parkinsonism  that  may  follow  carbon  monoxide  intoxication  and/or
manganese intoxication which was approved by the FDA in January 2015, and Zomig® (zolmitriptan) products, indicated for the treatment of migraine headaches, under the terms of a
Distribution, License, Development and Supply Agreement (“AZ Agreement”) with AstraZeneca UK Limited (“AstraZeneca”). Each of the Impax Generics and Impax Specialty Pharma
divisions  also  generates  revenue  from  research  and  development  services  provided  to  unrelated  third-party  pharmaceutical  entities.  See  “Item  15.  Exhibits  and  Financial  Statement
Schedules — Note 23. Segment Information,” for financial information about our segments for the years ended December 31, 2015, 2014 and 2013.

On  March  9,  2015,  we  completed  our  acquisition  of  Tower  Holdings,  Inc.  (“Tower”),  including  its  operating  subsidiaries  CorePharma  LLC  (“CorePharma”)  and  Amedra
Pharmaceuticals LLC (“Amedra Pharmaceuticals”), and Lineage Therapeutics, Inc. (“Lineage”) for a purchase price of approximately $691.3 million, net of approximately $41.5 million
of  cash  acquired  and  including  the  repayment  of  indebtedness  of  Tower  and  Lineage  (the  “Tower  acquisition”).  The  privately-held  companies  specialized  in  the  development,
manufacture  and  commercialization  of  complex  generic  and  branded  pharmaceutical  products.  For  additional  information  on  the  Tower  acquisition,  and  the  related  financing  of  the
acquisition, refer to “Item 15. Exhibits and Financial Statement Schedules - Note 2. Business Acquisitions” and “Note 14. Debt”.

In  connection  with  the  closing  of  the  Tower  acquisition,  we  renamed  the  operating  and  reporting  structure  of  our  two  divisions  into  Impax  Generics  and  Impax  Specialty
Pharma. Impax Generics includes our legacy Global Pharmaceuticals business as well as the acquired CorePharma and Lineage businesses. Impax Specialty Pharma includes the legacy
Impax Pharmaceuticals business as well as the acquired Amedra Pharmaceuticals business.

Our Strategy

We plan to continue to expand our Impax Generics division by targeting complex solid oral and alternative dosage form Abbreviated New Drug Applications (“ANDAs”) with
high revenue potential, including products with the potential to be first-to-file or first-to-market. Our products and product candidates are generally difficult to formulate and manufacture,
providing certain competitive advantages. In addition to our product pipeline of 25 pending applications at the FDA as of February 16, 2016, we are continuing to evaluate and pursue
external growth initiatives including acquisitions and partnerships.

The following information summarizes our generic pharmaceutical product development activities since inception through February 16, 2016:

●

112 ANDAs approved by the U.S. Food and Drug Administration (“FDA”),including one tentatively approved (i.e. satisfying substantive FDA requirements but remaining
subject to statutory restrictions). In addition, we have rights to market and/or share in profits to 14 approved ANDAs held by our third party alliance partners. The approved
ANDAs (including those held by our partners) include generic versions of brand name pharmaceuticals such as Adderall®, Lamictal ODT®, Lofibra®, Opana ER® (NDA
021610) and Solaraze®.

●

25 applications pending at the FDA that represent approximately $7.9 billion in 2015 U.S. product sales.

● A number of products in various stages of development for which applications have not yet been filed.

A core component of our strategy includes an ongoing focus in our Impax Specialty Pharma division on proprietary brand-name pharmaceutical products to treat CNS disorders
and other specialty segments. We believe that we have the research, development and formulation expertise to develop branded products that will deliver significant improvements over
existing  therapies.  We  plan  to  continue  investing  in  our  development  pipeline,  both  internally  and  through  acquisitions  and  partnerships  primarily  focused  on  late-stage  and  next
generation product opportunities.

Impax Generics Division

In  the  generic  pharmaceutical  market,  we  focus  our  efforts  on  developing,  manufacturing,  selling  and  distributing  complex  solid  dose  and  alternative  dosage  form  products
covering a broad range of therapeutic areas and having technically challenging drug-delivery mechanisms or unique product development formulations. We employ our technologies and
formulation expertise to develop generic products that reproduce brand-name products’ physiological characteristics  but do not infringe any valid patents relating to such brand-name
products.  Generic  products  contain  the  same  active  ingredient  and  are  of  the  same  route  of  administration,  dosage  form,  strength  and  indication(s)  as  brand-name  products  already
approved  for  use  in  the  United  States  by  the  FDA.  We  generally  focus  our  generic  product  development  on  brand-name  products  as  to  which  the  patents  covering  the  active
pharmaceutical  ingredient  have  expired  or  are  near  expiration,  and  we  employ  our  experience  to  develop  bioequivalent  versions  of  such  brand-name  products.  We  also  develop,
manufacture,  sell  and  distribute  specialty  generic  pharmaceuticals  that  we  believe  present  certain  competitive  advantages,  such  as  difficulty  in  raw  materials  sourcing,  complex
formulation or development characteristics or special handling requirements. We have generally obtained rights to our alternative dosage form products through third party alliance and
collaboration agreements, such as through our partnership agreement with TOLMAR, Inc. (“Tolmar”).

We sell and distribute generic pharmaceutical products primarily through four sales channels:

●

●

●

●

the “Impax Generics” sales channel : generic pharmaceutical prescription products we sell directly to wholesalers, large retail drug chains, and others;

the “Rx Partner” sales channel : generic prescription products sold through unrelated third-party pharmaceutical entities pursuant to alliance and collaboration agreements;

the “Private  Label”  sales  channel  :  generic  pharmaceutical  over-the-counter  (“OTC”)  and  prescription  products  we  sell  to  unrelated  third  parties  who  in-turn  sell  the
product under their own label; and

the  “OTC  Partner”  sales  channel  :  sales  of  generic  pharmaceutical  OTC  products  sold  through  unrelated  third-party  pharmaceutical  companies  pursuant  to  alliance,
collaboration and supply agreements.

As  of  February  16,  2016,  we  marketed  139  generic  pharmaceutical  products  representing  dosage  variations  of  55  different  pharmaceutical  compounds  through  our  Impax
Generics  division,  and  five  other  generic  pharmaceutical  products,  representing  dosage  variations  of  two  different  pharmaceutical  compounds,  through  our  alliance  and  collaboration
agreement  partners.  As of February  16, 2016, our marketed  generic  products  include,  but are  not limited  to, authorized  generic  Adderall  XR®, fenofibrate  (generic  to Lofibra®)  and
oxymorphone hydrochloride extended release tablets (AB rated to original OPANA® ER).

The Impax Specialty Pharma division is primarily focused on the development and promotion through our specialty sales force of proprietary branded pharmaceutical products
for the treatment of CNS disorders, which include migraine, multiple sclerosis, Parkinson’s disease and postherpetic neuralgia. We estimate there are approximately 16,000 neurologists
in the United States. Historically, a concentrated number of these neurologists are responsible for writing the majority of neurology prescriptions. CNS is the largest therapeutic category
in the United States with 2015 sales of about $72 billion, or 16.4% of the $437 billion U.S. prescription drug market.  CNS product sales grew 2% in 2015, compared to 11% growth for
the overall pharmaceutical market, while total CNS prescriptions increased 0.4%, slightly less than the overall pharmaceutical industry growth rate of 1.2%. (Source: IMS Health). 

Our branded pharmaceutical product portfolio consists of commercial CNS products and development stage projects. Our internally developed branded pharmaceutical product,
Rytary® (IPX066), an extended release oral capsule formulation of carbidopa-levodopa for the treatment of Parkinson’s disease, post-encephalitic parkinsonism, and parkinsonism that
may follow carbon monoxide intoxication and/or manganese intoxication, was approved by the FDA on January 7, 2015 and we began marketing the product in the United States in April
(the brand name of IPX066 outside of the United States)
2015. During the fourth quarter of 2015, we received marketing authorization from the European Commission for NUMIENT 
and we are currently engaged in discussions with potential partners to market NUMIENT 

outside the United States.

Impax Specialty Pharma is also engaged in the sale and distribution of four other branded products; the more significant include Zomig® (zolmitriptan) products, indicated for
the treatment of migraine headaches, under the terms of the AZ Agreement with AstraZeneca in the United States and in certain U.S. territories, and Albenza®, indicated for the treatment
of tapeworm infections.

We have a couple of product candidates that are in varying stages of development and we currently intend to expand our portfolio of branded pharmaceutical products primarily

through internal development and through licensing and acquisitions, with a focus on late-stage product opportunities. 

Alliance and Collaboration Agreements

We have entered into several alliance and collaboration  agreements with respect to certain of our products and services and may enter into similar  agreements in the future.
These agreements typically obligate us to deliver multiple goods and/or services over extended periods. Such deliverables include manufactured pharmaceutical products, exclusive and
semi-exclusive  marketing  rights,  distribution  licenses,  and  research  and  development  services.  Our  alliance  and  collaboration  agreements  often  include  milestones  and  provide  for
payments upon achievement of these milestones. For more information about the types of milestone events in our agreements and how we categorize them, see “Item 15. Exhibits and
Financial Statement Schedules — Note 20. Alliance and Collaboration Agreements.”

Impax Generics Division – Alliance and Collaboration Agreements

License and Distribution Agreement with Shire

In  January  2006,  we  entered  into  a  License  and  Distribution  Agreement  with  an  affiliate  of  Shire  Laboratories,  Inc.,  which  was  subsequently  amended  (“Prior  Shire
Agreement”), under which we received a non-exclusive license to market and sell an authorized generic of Shire’s Adderall XR® product (“AG Product”) subject to certain conditions,
but in any event by no later than January 1, 2010. We commenced sales of the AG Product in October 2009. On February 7, 2013, we entered into an Amended and Restated License and
Distribution  Agreement  with  Shire  (the  “Amended  and  Restated  Shire  Agreement”),  which  amended  and  restated  the  Prior  Shire  Agreement.  The  Amended  and  Restated  Shire
Agreement  was  entered  into  by  the  parties  in  connection  with  the  settlement  of  our  litigation  with  Shire  relating  to  Shire’s  supply  of  the  AG  Product  to  us  under  the  Prior  Shire
Agreement. During 2013, we received a payment of $48,000,000 from Shire in connection with such litigation settlement, which was recorded in the first quarter of 2013 under the line
item “Other Income” on our consolidated statement of operations.

Under the Amended and Restated Shire Agreement, Shire was required to supply the AG Product and we are responsible for marketing and selling the AG Product subject to the
terms and conditions thereof until the earlier of (i) the first commercial sale of our generic equivalent product to Adderall XR® and (ii) September 30, 2014 (the “Supply Term”), subject
to certain continuing obligations of the parties upon expiration or early termination of the Supply Term, including Shire’s obligation to deliver AG Products still owed to us as of the end
of  the  Supply  Term.  We  are  required  to  pay  a  profit  share  to  Shire  on  sales  of  the  AG  Product,  of  which  we  owed  a  profit  share  payable  to  Shire  of  $19,540,000,  $21,089,000  and
$20,406,000 on sales of the AG Product during the years ended December 31, 2015, 2014 and 2013, respectively, with a corresponding charge included in the cost of revenues line in our
consolidated statement of operations. Although the Supply Term expired on September 30, 2014, we are permitted under the terms of the agreement to sell AG Products that we hold in
our inventory or owed to us by Shire under the agreement until all such products are sold. We will continue to pay a profit share to Shire on sales of such products.

Development, Supply and Distribution Agreement with Tolmar, Inc.

In  June  2012,  we  entered  into  a  Development,  Supply  and  Distribution  Agreement  with  Tolmar  (“Tolmar  Agreement”).  Under  the  terms  of  the  Tolmar  Agreement,  Tolmar
granted us an exclusive license to commercialize up to 11 generic topical prescription drug products, including ten then approved products and one product pending approval at the FDA,
in  the  United  States  and  its  territories.  Under  the  terms  of  the  Tolmar  Agreement,  Tolmar  is  responsible  for  developing  and  manufacturing  the  products,  and  we  are  responsible  for
marketing and sale of the products. We are required to pay a profit share to Tolmar on sales of each product commercialized pursuant to the terms of the Tolmar Agreement. We owed a
profit share payable to Tolmar of $77,683,000, $15,995,000 and $3,905,000 on sales of the topical products during the years ended December 31, 2015, 2014 and 2013, respectively, with
a corresponding charge included in the Cost of Revenues line item on our consolidated statement of operations.

We paid Tolmar a $21,000,000 upfront payment upon signing of the agreement and pursuant to the terms of the agreement, are also required to make payments to Tolmar upon
the  achievement  of  certain  specified  milestone  events.  During  the  year  ended  December  31,  2012,  we  made  a  $1,000,000  milestone  payment  and  during  the  fourth  quarter  ended
December 31, 2013, we made a $12,000,000 payment to Tolmar, in each case upon Tolmar’s achievement of a regulatory milestone event. During the fourth quarter of 2014, we paid a
$2,000,000 milestone payment to Tolmar related to the Diclofenac Sodium Gel 3% (Solaraze®) product pursuant to the Tolmar Agreement in accordance with the terms thereof. During
the second quarter of 2015, we paid a $5.0 million milestone related to certain topical products pursuant to the Tolmar Agreement.

Product Acquisition Agreement with Teva Pharmaceuticals USA, Inc.

In  August  2013,  we,  through  our  Amedra  Pharmaceuticals  subsidiary,  entered  into  a  product  acquisition  agreement  (the  “Teva  Product  Acquisition  Agreement”)  with  Teva
Pharmaceuticals USA, Inc. (“Teva”) pursuant to which we acquired the assets (including the ANDA and other regulatory materials) and related liabilities related to Teva’s mebendazole
tablet  product  in  all  dosage  forms  (the  “Mebendazole  Tablet”).  We  have  the  potential  to  pay  up  to  $3,500,000  in  additional  contingent  milestone  payments  upon  the  achievement  of
predefined regulatory and commercialization milestones. We are also obligated to pay Teva a royalty payment based on net sales of the Mebendazole Tablet, including a specified annual
minimum royalty payment, subject to customary reductions and the other terms and conditions set forth in the Teva Product Acquisition Agreement.

Rx Partner and OTC Partner Alliance Agreements

We have entered into alliance agreements with unrelated third-party pharmaceutical companies pursuant to which our partner distributes a specified product or products which
we developed and, in some cases manufacture. Pursuant to these alliance agreements we typically receive payment on delivery of the product, and share in the resulting profits, or receive
a royalty or receive other payments from our partners. Our alliance agreements are separated into two sales channels, the “Rx Partner” sales channel, for generic prescription products
sold through our partners under their own label, and the “OTC Partner” sales channel, for sales of generic pharmaceutical OTC products sold through our partner under their own label.
The revenue recognized and the percentage of gross revenue for each of the periods noted, for the Rx Partner and the OTC Partner alliance agreements, was as follows:

We entered into a Strategic Alliance Agreement with Teva Pharmaceuticals Curacao N.V., a subsidiary of Teva Pharmaceutical Industries Limited, in June 2001, which was
subsequently  amended  (“Teva  Agreement”).  The  Teva  Agreement  commits  us  to  develop  and  manufacture,  and  Teva  to  distribute,  a  specified  number  of  controlled  release  generic
pharmaceutical  products  (“generic  products”),  each  for  a  10-year  period  or  such  longer  period  as  may  be  mutually  agreed  between  the  parties.  As  of  December  31,  2015,  we  were
supplying  Teva  with  oxybutynin  extended  release  tablets  (Ditropan  XL®  5,  10  and  15  mg  extended  release  tablets)  and  have  agreed  to  supply  another  product  (currently  under
development) to Teva; the other products under the Teva Agreement have either been returned to us, are being manufactured by Teva at its election, were voluntarily withdrawn from the
market or our obligations to supply such product had expired or were terminated in accordance with the agreement.

For more information about the Teva Agreement, see “Item 15. Exhibits and Financial Statement Schedules – Note 20. Alliance and Collaboration Agreements.”

OTC Partner Alliance Agreements

We have a Development, License and Supply Agreement with Pfizer, Inc., formerly Wyeth LLC (“Pfizer”) for a term of approximately 15 years, relating to our Loratadine and
Pseudoephedrine Sulfate 5 mg/120 mg 12-hour Extended Release Tablets and Loratadine and Pseudoephedrine Sulfate 10 mg/240 mg 24-hour Extended Release Tablets for the OTC
market.  We  previously  developed  the  products  and  are  currently  only  responsible  for  manufacturing  the  products,  and  Pfizer  is  responsible  for  marketing  and  sale.  The  agreement
included payments by us upon achievement of development milestones, as well as royalties paid to us by Pfizer on its sales of the product. Pfizer launched this product in May 2003 as
Alavert®  D-12  Hour.  In  February  2005,  the  agreement  was  partially  cancelled  with  respect  to  the  24-hour  Extended  Release  Product  due  to  lower  than  planned  sales  volume.  In
December 2011, we and Pfizer entered into an agreement with L. Perrigo Company (“Perrigo”), which was subsequently amended whereby the parties agreed that we would supply our
Loratadine and Pseudoephedrine Sulfate 5 mg/120 mg 12-hour Extended Release Tablets to Perrigo in the United States and its territories. The agreements with Pfizer and Perrigo are no
longer a core area of our business, and the over-the-counter pharmaceutical products we sell to Pfizer and Perrigo under the agreements are older products which are only sold to Pfizer
and to Perrigo. As noted above, we are currently only required to manufacture the products under its agreements with Pfizer and Perrigo. We recognize profit share revenue in the period
earned.

Research Partner Alliance Agreement

In  November  2008,  we  entered  into  a  Joint  Development  Agreement  with  Valeant  Pharmaceuticals  International,  Inc.,  formerly  Medicis  Pharmaceutical  Corporation
(“Valeant”),  providing  for  collaboration  in  the  development  of  five  dermatological  products,  including  four  of  our  generic  products  and  one  branded  advanced  form  of  Valeant’s
SOLODYN® product. Valeant paid us an upfront fee of $40.0 million in December 2008. We have also received an aggregate of $15.0 million in milestone payments consisting of two
$5.0  million  milestone  payments,  paid  by  Valeant  in  March  2009  and  September  2009,  a  $2.0  million  milestone  payment  received  in  December  2009,  and  a  $3.0  million  milestone
payment received in March 2011. We have the potential to receive up to an additional $8.0 million of contingent regulatory milestone payments as well as the potential to receive royalty
payments from sales, if any, by Valeant of its advanced form SOLODYN® product under this agreement. We believe that all of the milestones under this agreement are substantive and
expect to recognize the proceeds from these regulatory milestones as revenue when achieved. We do not expect to receive any of these additional milestone payments during the fiscal
year ending December 31, 2016. To the extent we commercialize any of the four generic dermatology products covered by the agreement, we will pay to Valeant a gross profit share on
sales of such products. We began selling one of the four dermatology products during the year ended December 31, 2011. During the three month period ended March 31, 2013, we
extended the revenue recognition period for the Joint Development Agreement from the previous recognition period ending in November 2013 to December 2014 due to changes in the
estimated timing of completion of certain research and development activities. All deferred revenue under the Joint Development Agreement was recognized as of December 31, 2014.

Impax Specialty Pharma – Alliance and Collaboration Agreements

Distribution, License, Development and Supply Agreement with AstraZeneca UK Limited

In January 2012, we entered into the AZ Agreement with AstraZeneca. Under the terms of the AZ Agreement, AstraZeneca granted to us an exclusive license to commercialize
the tablet, orally disintegrating tablet and nasal spray formulations of Zomig® (zolmitriptan) products for the treatment of migraine headaches in the United States and in certain U.S.
territories, except during an initial transition period when AstraZeneca fulfilled all orders of Zomig® products on our behalf and paid us the gross profit on such Zomig® product sales.
We  are  obligated  to  fulfill  certain  minimum  requirements  with  respect  to  the  promotion  of  currently  approved  Zomig®  products  as  well  as  other  dosage  strengths  of  such  products
approved by the FDA in the future. We may, but have no obligation to, develop and commercialize additional products containing zolmitriptan and additional indications for Zomig®,
subject to certain restrictions as set forth in the AZ Agreement. We will be responsible for conducting clinical studies and preparing regulatory filings related to the development of any
such additional products and would bear all related costs. In June 2015, the FDA approved the Zomig® nasal spray for use in pediatric patients 12 years of age or older for the acute
treatment of migraine with or without aura. During the term of the AZ Agreement, AstraZeneca will continue to be the holder of the NDA for existing Zomig® products, as well as any
future  dosage  strengths  thereof  approved  by  the  FDA,  and  will  be  responsible  for  certain  regulatory  and  quality-related  activities  for  such  Zomig®  products.  AstraZeneca  will
manufacture and supply Zomig® products to us and we will purchase our requirements of Zomig® products from AstraZeneca until a date determined in the AZ Agreement. Thereafter,
AstraZeneca may terminate its supply obligations upon certain advance notice, in which case we would have the right to manufacture or have manufactured our own requirements for the
applicable Zomig® product.

Under  the  terms  of  the  AZ  Agreement,  AstraZeneca  was  required  to  make  payments  to  us  representing  100%  of  the  gross  profit  on  sales  of  AstraZeneca-labeled  Zomig®
products  during  the  specified  transition  period.  Under  the  terms  of  the  AZ  Agreement,  we  made  quarterly  payments  totaling  $130.0  million  to  AstraZeneca  during  the  year  ended
December  31,  2012.  Beginning  in  January  2013,  we  became  obligated  to  pay  AstraZeneca  tiered  royalty  payments  based  on  net  sales  of  Zomig®  products,  depending  on  brand
exclusivity  and  subject  to  customary  reductions  and  other  terms  and  conditions  set  forth  in  the  AZ  Agreement.  We  are  also  obligated  to  pay  to  AstraZeneca  royalties  after  a  certain
specified date based on gross profit from sales of authorized generic versions of the Zomig® products subject to certain terms and conditions set forth in the AZ Agreement. In May 2013,
our exclusivity period for branded Zomig® tablets and orally disintegrating tablets expired and we launched authorized generic versions of those products in the United States. We owed
a  royalty  payable  to  AstraZeneca  of  $16,848,000,  $14,262,000  and  $36,113,000  for  the  years  ended  December  31,  2015,  2014  and  2013,  respectively,  with  a  corresponding  charge
included in the cost of revenues line on the consolidated statements of income .

Beginning  after  December  31,  2015,  we  may  terminate  the  AZ  Agreement  for  convenience  upon  specified  notice.  We  may  also  terminate  the  AZ  Agreement  if  certain  of
AstraZeneca’s  annual  manufacturing  costs  reflected  in  the  supply  price  increase  by  more  than  a  certain  threshold.  The  AZ  Agreement  may  also  be  terminated  under  certain  other
circumstances, including for material breach, as set forth in the AZ Agreement.

Development and Co-Promotion Agreement with Endo Pharmaceuticals Inc.

In  June  2010,  we  entered  into  a  Development  and  Co-Promotion  Agreement  (“Endo  Agreement”)  with  Endo  Pharmaceuticals  Inc.  ("Endo")  under  which  we  agreed  to
collaborate in the development and commercialization of a next-generation advanced form of our lead brand product candidate ("Endo Agreement Product"). The Endo Agreement was
terminated  upon  mutual  agreement  by  the  parties  effective  December  23,  2015.  Under  the  provisions  of  the  Endo  Agreement,  in  June  2010,  Endo  paid  to  us  a  $10.0  million  upfront
payment. Prior to termination of the agreement, we also had the potential to receive up to an additional $30.0 million of contingent milestone payments.

Agreement with DURECT Corporation

In  2014,  we  entered  into  an  agreement  with  DURECT  Corporation  (“Durect”)  granting  us  the  exclusive  worldwide  rights  to  develop  and  commercialize  DURECT’s
investigational transdermal bupivacaine patch for the treatment of pain associated with post-herpetic neuralgia (PHN), which we refer to as IPX239. We paid Durect a $2,000,000 up-
front  payment  upon  signing  of  the  agreement.  We  also  have  the  potential  to  pay  up  to  $61,000,000  in  additional  contingent  milestone  payments  upon  the  achievement  of  predefined
development and commercialization milestones. If IPX239 is commercialized, we would also be obligated to pay Durect a tiered royalty based on product sales.

Our Controlled-Release Technology

We have developed a number of different controlled-release delivery technologies which may be utilized with a variety of oral dosage forms and drugs. Controlled-release drug
delivery technologies are designed to release drug dosages at specific times and in specific locations in the body and generally provide more consistent and appropriate drug levels in the
bloodstream than immediate-release dosage forms. Controlled-release pharmaceuticals may improve drug efficacy, ensure greater patient compliance with the treatment regimen, reduce
side effects or increase drug stability and be more patient friendly by reducing the number of times a drug must be taken.

We believe our controlled-release drug delivery technologies are flexible and can be applied to develop a variety of pharmaceutical products, both generic and branded. Our
technologies  utilize  a  variety  of  polymers  and  other  materials  to  encapsulate  or  entrap  the  active  pharmaceutical  ingredients  and  to  release  them  at  varying  rates  or  at  predetermined
locations in the gastrointestinal tract.

Competition

The  pharmaceutical  industry  is  highly  competitive  and  is  affected  by  new  technologies,  new  developments,  government  regulations,  health  care  legislation,  availability  of
financing, and other factors. Many of our competitors have longer operating histories and substantially greater financial, research and development, marketing, and other resources than
we  have.  We  compete  with  numerous  other  companies  that  currently  operate,  or  intend  to  operate,  in  the  pharmaceutical  industry,  including  companies  that  are  engaged  in  the
development  of  controlled-release  drug  delivery  technologies  and  products,  and  other  manufacturers  that  may  decide  to  undertake  development  of  such  products.  Our  principal
competitors in the generic pharmaceutical products market are Teva Pharmaceutical Industries Ltd., Allergan Inc., Mylan N.V., Sun Pharmaceutical Industries Ltd., Lannett Company,
Inc., Lupin Pharmaceuticals, Inc., Endo International plc and Sandoz.

Due to our focus on relatively hard to replicate controlled-release products, competition in the generic pharmaceutical market is sometimes limited to those competitors who

possess the appropriate drug delivery technology. The principal competitive factors in the generic pharmaceutical market are:

●
●
●
●
●

the ability to introduce generic versions of products promptly after a patent expires;
price;
product quality;
customer service (including maintenance of inventories for timely delivery); and
the ability to identify and market niche products.

In the brand-name pharmaceutical market, our principal competitors are pharmaceutical companies that are focused on Parkinson’s disease and other CNS disorders. In addition,
with respect to products that we are developing internally and/or any additional products we may in-license from third parties, we expect that we will face increased competition from
large pharmaceutical companies, drug delivery companies and other specialty pharmaceutical companies that have focused on the same disorders as our branded products.

A description of the competition we face from brand-name and generic pharmaceutical companies is included in “Item 1A. Risk Factors”.

Sales and Marketing

We market and sell our generic pharmaceutical prescription drug products within the continental United States and the Commonwealth of Puerto Rico. We have not made sales
in any other jurisdictions over the last three fiscal years. We derive a substantial portion of our revenue from sales to a limited number of customers. The customer base for our products
consists  primarily  of  drug  wholesalers,  warehousing  chain  drug  stores,  mass  merchandisers,  and  mail-order  pharmacies.  We  market  our  products  both  directly,  through  our  Impax
Generics  and  Impax  Specialty  Pharma  divisions,  and  indirectly  through  our  Rx  Partner  and  OTC  Partner  alliance  and  collaboration  agreements.  Together,  our  five  major  customers,
McKesson Corporation, Cardinal Health, Amerisource-Bergen, CVS Caremark Corporation and N.C. Mutual, accounted for 89% of our gross revenue for the year ended December 31,
2015. These five customers individually accounted for 46%, 22%, 19%, 1% and 1%, respectively, of our total gross revenue for the year ended December 31, 2015. We do not have long-
term contracts in effect with our five major customers. A reduction in or loss of business with any one of these customers, or any failure of a customer to pay us on a timely basis, would
adversely affect our business.

Manufacturing and Distribution

We source our finished dosage form products from our own facilities in Hayward, California; Middlesex, New Jersey; and Taiwan. We also use several contract manufacturers
for this purpose. During 2015, we restructured our packaging and distribution operations. As a result, we closed our Philadelphia packaging site and all of our company-wide distribution
operations were outsourced to United Parcel Services (UPS).

We maintain an inventory of our products in connection with our obligations under our alliance and collaboration agreements. In addition, for products pending approval, we
may produce batches for inventory in anticipation of the launch of the products. In the event that FDA approval is denied or delayed, we could be exposed to the risk of this inventory
becoming obsolete.

Raw Materials

The active chemical raw materials essential to our business are generally readily available from multiple sources in the United States and throughout the world. Certain raw
materials used in the manufacture of our products are, however, available from limited sources and, in some cases, a single source. Although we have not experienced any material delays
in receipt of raw materials to date, any curtailment in the availability of such raw materials could result in production or other delays or, in the case of products for which only one raw
material supplier exists or has been approved by the FDA, a material loss of sales with consequent adverse effects on our business and results of operations. Also, because raw material
sources for pharmaceutical products must generally be identified and approved by regulatory authorities, changes in raw material suppliers may result in production delays, higher raw
material costs, and loss of sales and customers. We obtain a portion of our raw materials from foreign suppliers, and our arrangements with such suppliers are subject to, among other
risks, FDA approval, governmental clearances, export duties, political instability, and restrictions on the transfers of funds.

Those  of  our  raw  materials  that  are  available  from  a  limited  number  of  suppliers  include  Bendroflumethiazide,  Chloroquine  Phosphate,  Colestipol,  Digoxin,  Fenofibrate,
Methyltestosterone,  Nadolol  and  Pyridostigmine,  all  of  which  are  active  pharmaceutical  ingredients.  The  manufacturers  of  several  of  these  products  are  sole-source  suppliers.  Only  a
couple of our active ingredients are covered by long-term supply agreements and, although to date we have only experienced occasional interruptions in supplies, we cannot assure that
we will continue to receive uninterrupted or adequate supplies of such raw materials.

Any inability to obtain raw materials on a timely basis, or any significant price increases not passed on to customers, could have a material adverse effect on our business, results

of operations and financial condition.

Quality Control

We have in the past received a warning letter and Form 483 observations from the FDA regarding certain operations within our manufacturing network.

●

In late May 2011, we received a warning letter from the FDA related to an on-site FDA inspection of our Hayward, California manufacturing facility citing deviations from
current  Good  Manufacturing  Practices  (“cGMP”),  which  are  extensive  regulations  governing  manufacturing  practices  for  finished  pharmaceutical  products  and  which
establish requirements for manufacturing processes, stability testing, record keeping and quality standards and controls.

● During fiscal years 2012, 2013 and 2014, the FDA conducted cGMP inspections of our Hayward manufacturing facility and during the quarter ended June 30, 2015, the

FDA conducted a cGMP and Pre-Approval Inspection at the facility. At the conclusion of each inspection, we received a Form 483.

●

●

In July 2014, we received a Form 483 after the FDA conducted a cGMP and Pre-Approval Inspection of our Taiwan manufacturing facility.

In March 2015, we received a Form 483 at our Horsham, Pennsylvania operations after the FDA conducted a pharmacovigilance inspection.

During 2015, we successfully resolved the warning letter on our Hayward manufacturing facility and we also received the Establishment Inspection Reports (“EIRs”) for each of
the aforementioned FDA inspections indicating acceptance of our corrective actions and closure by the FDA of each such inspection. Since our receipt of the 2015 notification from the
FDA regarding closure of the warning letter, the FDA has approved a number of products that are manufactured at our Hayward facility.

We remain committed to continuing to improve our quality control and manufacturing practices. We cannot be assured, however, that the FDA will continue to be satisfied with
our  corrective  actions  and  with  our  quality  control  and  manufacturing  systems  and  standards.  If  we  receive  any  future  FDA  observations,  we  may  be  subject  to  regulatory  action
including,  among  others,  monetary  sanctions  or  penalties,  product  recalls  or  seizure,  injunctions,  total  or  partial  suspension  of  production  and/or  distribution,  and  suspension  or
withdrawal of regulatory approvals. Further, other federal agencies, our customers and partners in our alliance, development, collaboration and other partnership agreements with respect
to our products and services may take any such Form 483 observations or warning letters into account when considering the award of contracts or the continuation or extension of such
partnership  agreements.  If  we  receive  any  future  Form  483  observations  or  warning  letters  from  the  FDA,  our  business,  consolidated  results  of  operations  and  consolidated  financial
condition could be materially and adversely affected.

Research and Development

We conduct most of our research and development activities at our facilities in Hayward, California and Middlesex, NJ, with a staff of 157 employees as of December 31, 2015.

In addition, we have outsourced a number of research and development projects to third-party laboratories.

We  spent  approximately  $77.0  million,  $78.6  million  and  $68.9  million  on  research  and  development  activities  during  the  years  ended  December  31,  2015,  2014 and  2013,
respectively, as more fully set out in the tables below (in millions). The research and development expenses in the year ended December 31, 2015 included $6.4 million related to an
impairment of acquired in-process research and development product rights, included in the line item “Other” below.

We do not generally track research and development expense by individual product in either the Impax Generics division or the Impax Specialty Pharma division.

In the Impax Generics division, we focus our research and development efforts based on drug-delivery technology and on products that we believe may have certain competitive
advantages,  rather  than  on  any  particular  therapeutic  area.  As  of  February  16,  2016,  the  Impax  Generics  division  had  25  product  applications  pending  with  the  FDA  and  another  18
products in development. Accordingly, we believe that our generic pipeline products will, in the aggregate, generate a significant amount of revenue for us in the future. However, while a
generic product is still in development, we are unable to predict the level of commercial success that the product may ultimately achieve given the uncertainties relating to the successful
and timely completion of bioequivalence studies, ANDA filing, receipt of marketing approval and resolution of any related patent litigation, as well as the amount of competition in the
market at the time of product launch and thereafter and other factors detailed in “Item 1A. Risk Factors.” Additionally, we do not believe that any individual generic pipeline product is
currently  significant  in  terms  of  accrued  or  anticipated  research  and  development  expense  given  the  large  volume  of  products  under  development  in  the  Impax  Generics  division,  as
detailed  above.  Further,  on  a  per  product  basis,  development  costs  for  generic  products  tend  to  be  significantly  lower  than  for  branded  products,  as  the  process  for  establishing
bioequivalence is significantly less extensive than the standard clinical trial process. The regulatory approval process is significantly less onerous as well compared to the process for
branded products.

In  the  Impax  Specialty  Pharma  division,  we  currently  market  one  internally  developed  branded  pharmaceutical  product,  Rytary®  (IPX066)  for  the  treatment  of  Parkinson’s
disease, post-encephalitic parkinsonism, and parkinsonism that may follow carbon monoxide intoxication and/or manganese intoxication, which was approved by the FDA on January 7,
2015 and which we launched in the United States in April 2015. We also have a number of product candidates that are in varying stages of development. While we believe the pipeline
products  in  this  division  are  potentially  viable,  profitable  product  candidates  for  us,  given  the  uncertainties  relating  to  the  successful  completion  of  clinical  trials,  the  FDA  approval
process for branded products, reimbursement levels, the amount of competition at the time of product launch and thereafter and other factors detailed in “Item 1A. Risk Factors,” such
pipeline products are too early in the development process to be considered significant at this point in time.

Regulation   

The  manufacturing  and  distribution  of  pharmaceutical  products  are  subject  to  extensive  regulation  by  the  federal  government,  primarily  through  the  FDA  and  the  Drug
Enforcement Administration (“DEA”), and to a lesser extent by state and local governments. The Food, Drug, and Cosmetic Act, Controlled Substances Act and other federal statutes and
regulations  govern  or  influence  the  manufacture,  labeling,  testing,  storage,  record  keeping,  approval,  advertising  and  promotion  of  our  products.  Facilities  used  in  the  manufacture,
packaging, labeling and repackaging of pharmaceutical products must be registered with the FDA and are subject to FDA inspection to ensure that drug products are manufactured in
accordance  with  current  Good  Manufacturing  Practices.  Noncompliance  with  applicable  requirements  can  result  in  product  recalls,  seizure  of  products,  injunctions,  suspension  of
production, refusal of the government to enter into supply contracts or to approve drug applications, civil penalties and criminal fines, and disgorgement of profits.

FDA approval is required before any “new drug” may be marketed, including new formulations, strengths, dosage forms and generic versions of previously approved drugs.

Generally, the following two types of applications are used to obtain FDA approval of a “new drug.”

New Drug Application (“NDA”). For a drug product containing an active ingredient not previously approved by the FDA, a prospective manufacturer must submit a complete
application containing the results of clinical studies supporting the drug product’s safety and efficacy. An NDA is also required for a drug with a previously approved active ingredient if
the drug will be used to treat an indication for which the drug was not previously approved or if the dosage form, strength or method of delivery is changed. The process required by the
FDA before a pharmaceutical product may be approved for marketing in the U.S. generally involves the steps listed below, which could take from approximately three to more than ten
years to complete.

Laboratory and clinical tests;
●
●
Submission of an Investigational New Drug (“IND”) application, which must become effective before clinical studies may begin;
● Adequate and well-controlled human clinical studies to establish the safety and efficacy of the proposed product for its intended use;
●

Submission of an NDA containing the results of the preclinical tests and clinical studies establishing the safety and efficacy of the proposed product for its intended use, as
well as extensive data addressing such matters such as manufacturing and quality assurance;
Scale-up to commercial manufacturing; and
FDA approval of an NDA.

●
●

As noted above, the submission of an NDA is not a guarantee that the FDA will find it complete and accept it for filing. The FDA reviews all NDAs submitted before it accepts
them for filing. It may refuse to file the application and instead request additional information, in which case, the application must be resubmitted with the supplemental information.
After the application is deemed filed by the FDA, FDA staff will review an NDA to determine, among other things, whether a product is safe and efficacious for its intended use.

If, after reviewing the NDA, the FDA determines that the application cannot be approved in its current form, the FDA sends the NDA applicant a Complete Response Letter
identifying all outstanding deficiencies that preclude final approval. The FDA then halts its review until the applicant resubmits the NDA with new information designed to address the
deficiencies. An applicant receiving a Complete Response Letter may resubmit the application with data and information addressing the FDA’s concerns or requirements, withdraw the
application without prejudice to a subsequent submission of a related application or request a hearing on whether there are grounds for denying approval of the application. If a product
receives  regulatory  approval,  the  approval  may  be  significantly  limited  to  specific  diseases  and  dosages  or  the  indications  for  use  may  otherwise  be  limited,  which  could  restrict  the
commercial value of the product. In addition, the FDA may require an applicant to conduct Phase 4 testing which involves clinical trials designed to further assess a drug’s safety and
effectiveness  after  NDA  approval,  and  may  require  surveillance  programs  to  monitor  the  safety  of  approved  products  which  have  been  commercialized.  Once  issued,  the  FDA  may
withdraw product approval if ongoing regulatory requirements are not met or if safety or efficacy questions are raised after the product reaches the market. The agency may also impose
requirements that the NDA holder conduct new studies, make labeling changes, implement Risk Evaluation and Mitigation Strategies, and take other corrective measures.

Abbreviated  New  Drug  Application  (“ANDA”).  For  a  generic  version  of  an  approved  drug  —  a  drug  product  that  contains  the  same  active  ingredient  as  a  drug  previously
approved by the FDA and is in the same dosage form and strength, utilizes the same method of delivery and will be used to treat the same indications as the approved product — the FDA
requires  only  an  abbreviated  new  drug  application  that  ordinarily  need  not  include  clinical  studies  demonstrating  safety  and  efficacy.  An  ANDA  typically  requires  only  data
demonstrating that the generic formulation is bioequivalent to the previously approved “reference listed drug,” indicating that the rate of absorption and levels of concentration of the
generic drug in the body do not show a significant difference from those of the reference listed drug. In July 2012, the Generic Drug Fee User Amendments of 2012 (“GDUFA”) was
enacted into law. The GDUFA legislation implemented fees for new ANDA applications, Drug Master Files, product and establishment fees and a one-time fee for back-logged ANDA
applications pending approval as of October 1, 2012. In return, the program is intended to provide faster and more predictable ANDA reviews by the FDA and increased inspections of
drug facilities. Under GDUFA, generic product companies face significant penalties for failure to pay the new user fees, including rendering an ANDA application not “substantially
complete” until the fee is paid. Prior to the implementation of GDUFA, the FDA took an average of approximately 30 months to approve an ANDA.

Under the Drug Price Competition and Patent Term Restoration Act of 1984, commonly known as the “Hatch-Waxman Act”, which established the procedures for obtaining
approval of generic drugs, an ANDA filer must make certain patent certifications that can result in significant delays in obtaining FDA approval. If the applicant intends to challenge the
validity  or  enforceability  of  an  existing  patent  covering  the  reference  listed  drug  or  asserts  that  its  drug  does  not  infringe  such  patent,  the  applicant  files  a  so  called  “Paragraph  IV”
certification and notifies the patent holder that it has done so, explaining the basis for its belief that the patent is not infringed or is invalid or unenforceable. If the patent holder initiates a
patent infringement suit within 45 days after receipt of the Paragraph IV Certification, the FDA is automatically prevented from approving an ANDA until the earlier of 30 months after
the  date  the  Paragraph  IV  Certification  is  given  to  the  patent  holder,  expiration  of  the  patents  involved  in  the  certification,  or  when  the  infringement  case  is  decided  in  the  ANDA
applicant’s  favor.  In  addition,  the  first  company  to  file  an  ANDA  for  a  given  drug  containing  a  Paragraph  IV  certification  can  be  awarded  180  days  of  market  exclusivity  following
approval of its ANDA, during which the FDA may not approve any other ANDAs for that drug product.

During any period in which the FDA is required to withhold its approval of an ANDA due to a statutorily imposed non-approval period, the FDA may grant tentative approval to
an  applicant’s  ANDA.  A  tentative  approval  reflects  the  FDA’s  preliminary  determination  that  a  generic  product  satisfies  the  substantive  requirements  for  approval,  subject  to  the
expiration of all statutorily imposed non-approval periods. A tentative approval does not allow the applicant to market the generic drug product.

The Hatch-Waxman Act contains additional provisions that can delay the launch of generic products. A five year marketing exclusivity period is provided for new chemical
compounds, and a three year marketing exclusivity period is provided for approved applications containing new clinical investigations essential to an approval, such as a new indication
for use, or new delivery technologies, or new dosage forms. The three year marketing exclusivity period applies to, among other things, the development of a novel drug delivery system,
as well as a new use. In addition, companies can obtain six additional months of exclusivity if they perform pediatric studies of a reference listed drug product. The marketing exclusivity
provisions  apply  to  both  patented  and  non-patented  drug  products.  The  Act  also  provides  for  patent  term  extensions  to  compensate  for  patent  protection  lost  due  to  time  taken  in
conducting FDA required clinical studies and during FDA review of NDAs.

The  Generic  Drug  Enforcement  Act  of  1992  establishes  penalties  for  wrongdoing  in  connection  with  the  development  or  submission  of  an  ANDA.  In  general,  the  FDA  is
authorized to temporarily bar companies, or temporarily or permanently bar individuals, from submitting or assisting in the submission of an ANDA, and to temporarily deny approval
and suspend applications to market generic drugs under certain circumstances. In addition to debarment, the FDA has numerous discretionary disciplinary powers, including the authority
to withdraw approval of an ANDA or to approve an ANDA under certain circumstances and to suspend the distribution of all drugs approved or developed in connection with certain
wrongful conduct. The FDA may also withdraw product approval or take other correct measures  if ongoing regulatory requirements  are not met or if safety or efficacy questions are
raised after the product reaches the market.

Other Regulatory Requirements

We are subject to the Maximum Allowable Cost Regulations, which limit reimbursements for certain generic prescription drugs under Medicare, Medicaid, and other programs
to the lowest price at which these drugs are generally available. In many instances, only generic prescription drugs fall within the regulations’ limits. Generally, the pricing and promotion
of, method of reimbursement and fixing of reimbursement levels for, and the reporting to federal and state agencies relating to drug products is under active review by federal, state and
local governmental entities, as well as by private third-party reimbursers and individuals under whistleblower statutes. At present, the Justice Department and U.S. Attorneys Offices and
State Attorneys General have initiated investigations, reviews, and litigation into industry-wide pharmaceutical pricing and promotional practices, and whistleblowers have filed qui tam
suits. We cannot predict the results of those reviews, investigations, and litigation, or their impact on our business.

13

 
 
 
 
 
 
 
 
 
 
Virtually every state, as well as the District of Columbia, has enacted legislation permitting the substitution of equivalent generic prescription drugs for brand-name drugs where

authorized or not prohibited by the prescribing physician, and some states mandate generic substitution in Medicaid programs.

In  addition,  numerous  state  and  federal  requirements  exist  for  a variety  of  controlled  substances,  such  as  narcotics,  that  may  be  part  of  our product  formulations.  The  DEA,

which has authority similar to the FDA’s and may also pursue monetary penalties, and other federal and state regulatory agencies have far reaching authority.

The State of California requires that any manufacturer, wholesaler, retailer or other entity in California that sells, transfers, or otherwise furnishes certain so called precursor
substances  must  have  a  permit  issued  by  the  California  Department  of  Justice,  Bureau  of  Narcotic  Enforcement.  The  substances  covered  by  this  requirement  include  ephedrine,
pseudoephedrine, norpseudoephedrine, and phenylpropanolamine, among others. The Bureau has authority to issue, suspend and revoke precursor permits, and a permit may be denied,
revoked or suspended for various reasons, including (i) failure to maintain effective controls against diversion of precursors to unauthorized persons or entities; (ii) failure to comply with
the Health and Safety Code provisions relating to precursor substances, or any regulations adopted thereunder; (iii) commission of any act which would demonstrate actual or potential
unfitness to hold a permit in light of the public safety and welfare, which act is substantially related to the qualifications, functions or duties of the permit holder; or (iv) if any individual
owner, manager, agent, representative or employee of the permit applicant/permit holder willfully violates any federal, state or local criminal statute, rule, or ordinance relating to the
manufacture, maintenance, disposal, sale, transfer or furnishing of any precursor substances.

Patents, Trademarks and Licenses

We own or license a number of patents in the U.S. and other countries covering certain products and product candidates and have also developed brand names and trademarks for
other products and product candidates. Generally, the brand pharmaceutical business relies upon patent protection to ensure market exclusivity for the life of the patent. We consider the
overall protection of our patents, trademarks and license rights to be of material value and act to protect these rights from infringement. However, our business is not dependent upon any
single patent, trademark or license.

In the branded pharmaceutical industry, the majority of an innovative product’s commercial value is usually realized during the period in which the product has market exclusivity.
In the U.S. and some other countries, when market exclusivity expires and generic versions of a product are approved and marketed, there can often be very substantial and rapid declines
in  the  branded  product’s  sales.  The  rate  of  this  decline  varies  by country  and  by  therapeutic  category;  however,  following  patent  expiration,  branded  products  often  continue  to  have
market viability based upon the goodwill of the product name, which typically benefits from trademark protection.

An innovator product’s market exclusivity is generally determined by two forms of intellectual property: patent rights held by the innovator company and any regulatory forms of

exclusivity to which the innovator is entitled.

Patents are a key determinant of market exclusivity for most branded pharmaceuticals. Patents provide the innovator with the right to exclude others from practicing an invention
related  to  the  medicine.  Patents  may  cover,  among  other  things,  the  active  ingredient(s),  various  uses  of  a  drug  product,  pharmaceutical  formulations,  drug  delivery  mechanisms  and
processes for (or intermediates useful in) the manufacture of products. Protection for individual products extends for varying periods in accordance with the expiration dates of patents in
the various countries. The protection afforded, which may also vary from country to country, depends upon the type of patent, its scope of coverage and the availability of meaningful
legal remedies in the country.

Market exclusivity is also sometimes influenced by regulatory exclusivity rights. Many developed countries provide certain non-patent incentives for the development of medicines.
For  example,  the  U.S.,  the  EU  and  Japan  each  provide  for  a  minimum  period  of  time  after  the  approval  of  a  new  drug  during  which  the  regulatory  agency  may  not  rely  upon  the
innovator’s data to approve a competitor’s generic copy. Regulatory exclusivity rights are also available in certain markets as incentives for research on new indications, on orphan drugs
and on medicines useful in treating pediatric patients. Regulatory exclusivity rights are independent of any patent rights and can be particularly important when a drug lacks broad patent
protection. However, most regulatory forms of exclusivity do not prevent a competitor from gaining regulatory approval prior to the expiration of regulatory data exclusivity on the basis
of the competitor’s own safety and efficacy data on its drug, even when that drug is identical to that marketed by the innovator.

14

 
 
 
 
 
 
 
 
 
 
 
 
We estimate the likely market exclusivity period for each of our branded products on a case-by-case basis. It is not possible to predict the length of market exclusivity for any of our
branded products with certainty because of the complex interaction between patent and regulatory forms of exclusivity, and inherent uncertainties concerning patent litigation. There can
be no assurance that a particular product will enjoy market exclusivity for the full period of time that we currently estimate or that the exclusivity will be limited to the estimate.

In  addition  to  patents  and  regulatory  forms  of  exclusivity,  we  also  market  products  with  trademarks.  Trademarks  have  no  effect  on  market  exclusivity  for  a  product,  but  are
considered to have marketing value. Trademark protection continues in some countries as long as used; in other countries, as long as registered. Registration is for fixed terms and may be
renewed indefinitely.

Environmental Laws

We are subject to comprehensive federal, state and local environmental laws and regulations that govern, among other things, air polluting emissions, waste water discharges,
solid  and  hazardous  waste  disposal,  and  the  remediation  of  contamination  associated  with  current  or  past  generation  handling  and  disposal  activities.  We  are  subject  periodically  to
environmental compliance reviews by various environmental regulatory agencies. While it is impossible to predict accurately the future costs associated with environmental compliance
and potential remediation activities, compliance with environmental laws is not expected to require significant capital expenditures and has not had, and is not expected to have, a material
adverse effect on our business, operations or financial condition.

Available Information

We maintain an Internet website at the following address: www.impaxlabs.com. We make available on or through our Internet website certain reports and amendments to those
reports, as applicable, that we file with or furnish to the Securities and Exchange Commission (the “SEC”) in accordance with the Securities Exchange Act of 1934, as amended (the
“Exchange Act”). These include our Annual Report on Form 10-K, our Quarterly Reports on Form 10-Q and our Current Reports on Form 8-K. Our website also includes our Code of

incorporated by reference in this Annual Report on Form 10-K and shall not be deemed “filed” under the Exchange Act.

Corporate and Other Information

We were incorporated in the State of Delaware in 1995. Our corporate headquarters are located at 30831 Huntwood Avenue, Hayward, California, 94544. We were formerly
known as Global Pharmaceutical Corporation until December 14, 1999, when Impax Pharmaceuticals, Inc., a privately held drug delivery company, merged into Global Pharmaceutical
Corporation and the name of the resulting entity was changed to Impax Laboratories, Inc.

Unless otherwise indicated, all product sales data and U.S. market size data in this Annual Report on Form 10-K are based on information obtained from IMS Health, unrelated

third-party providers of prescription market data. We did not independently engage IMS Health to provide this information.

Employees

As  of  December  31,  2015,  we  had  1,290  full-time  employees,  of  which  563  were  in  operations,  157  in  research  and  development,  328  in  the  quality  area,  181  in  legal  and

administration, and 61 in sales and marketing. None of our employees are subject to collective bargaining agreements with labor unions, and we believe our employee relations are good.

Item 1A.     Risk Factors

An investment in our common stock involves a high degree of risk. In deciding whether to invest in our common stock, you should consider carefully the following risk factors,
as well as the other information included in this Annual Report on Form 10-K. The materialization of any of these risks could have a material adverse effect on our business, results of
operations and financial condition. This Annual Report on Form 10-K contains forward looking statements that involve risks and uncertainties. Our actual results could differ materially
from  the  results  discussed  in  the  forward  looking  statements.  Factors  that  could  cause  or  contribute  to  these  differences  include  those  discussed  in  this  “Risk  Factors”  section.  See
“Forward-Looking Statements” on page 1 of this Annual Report on Form 10-K.

Risks Related to Our Business

Our revenues and operating income could fluctuate significantly.  

Our revenues and operating results may vary significantly from year-to-year and quarter to quarter as well as in comparison to the corresponding quarter of the preceding year.

Variations may result from, among other factors:

the timing of FDA approvals we receive;
the timing of process validation, product launches, and market acceptance of such products launched;
changes in the amount we spend to research, develop, acquire, license or promote new products;
the outcome of our clinical trial programs;
serious or unexpected health or safety concerns with our products, the brand products we have genericized, or our product candidates;
the introduction of new products by others that render our products obsolete or noncompetitive;
the ability to maintain selling prices and gross margins on our products;
changes in our policies regarding returns, rebates, allowances and chargebacks for our products;
the outcome of our patent infringement litigation and other litigation matters and expenditures as a result of such litigation;
the ability to comply with complex governmental regulations which deal with many aspects of our business;
changes in coverage and reimbursement policies of health plans and other health insurers, including changes to Medicare, Medicaid and similar state programs;
increases in the cost of raw materials used to manufacture our products;

As an illustration, we earned significant revenues and gross profit from sales of our authorized generic Adderall XR 

 products during fiscal years 2012, 2013 and 2014 and
from sales of our authorized generic Renvela 
products, we were dependent on a third party
products during fiscal year 2014. With respect to our authorized generic Adderall XR 
pharmaceutical  company  to  supply  us  with  such  products  we  market  and  sell  through  our  Generics  Division.  Our  supply  agreement  with  such  third  party  for  the  supply  of  generic
Adderall XR  products expired on September 30, 2014. Although we continue to market and sell generic Adderall XR 
 products that we have in inventory, unless we are able to timely
and successfully launch our corresponding generic product to Adderall XR 
, we will not be able to continue to earn uninterrupted future revenue from the sale of such products after we
exhaust our inventory. With respect to our generic Renvela  products, during the second quarter of fiscal year 2014, we were granted a license to sell an allotment of a specified number
of bottles of the product under the terms of a third party settlement agreement and the sales from such product, a high margin product, contributed to significant revenue in our Generics
products  in  fiscal  year  2015,  which  contributed  to  reduced  gross  profit  in  our
Division  during  fiscal  2014.  We  did  not  receive  any  revenues  from  our  authorized  generic  Renvela 
Generics Division during certain periods in 2015, as compared to the corresponding periods in the prior year.

In our branded products division, we earned significant revenues and gross profit from sales of our Impax-labeled Zomig 

 (zolmitriptan) tablet, orally disintegrating tablet and
nasal  spray  formulation  products  that  we  began  selling  during  the  year  ended  December  31,  2012  pursuant  to  our  Distribution,  License,  Development  and  Supply  Agreement  with
AstraZeneca.  In May 2013, our exclusivity period for branded Zomig® tablets and orally disintegrating tablets expired and we experienced diminution of our sales revenue and gross
profit from those products as a result of generic competition. We launched authorized generic versions of those products in the United States. We continue to commercialize the branded
Zomig® nasal spray which has U.S. patents expiring as late as May 2021, which patents have been challenged by an ANDA filer seeking to market a generic to Zomig® nasal spray.
During  fiscal  year  2015,  we  began  marketing  Rytary 
,  our  internally  developed  extended  release  oral  capsule  formulation  of  carbidopa-levodopa  for  the  treatment  of  Parkinson’s
disease, post-encephalitic parkinsonism, and parkinsonism that may follow carbon monoxide intoxication and/or manganese intoxication for sale in the United States, which contributed
that expire as late as December 2028, which patents have been challenged by an
to sales revenue in our branded products division during the year. We have patents covering Rytary

Any diminution of sales revenue and/or gross profit from such products or our other significant products due to existing or additional competition, product supply or any other

reasons in future periods may materially and adversely affect our results of operations in such periods.

Due to the fluctuations in revenue and operating results due to factors discussed in greater detail below, our quarterly operating results are difficult to predict and may fluctuate
significantly  from  period  to  period.  We  cannot  predict  with  any  certainty  the  timing  or  level  of  sales  of  our  products  in  the  future.  As  a  result,  period-to-period  comparisons  of  our
operating results should not be relied upon as indications of our future performance and any full-year financial forecast should not be relied upon as a guarantee of future performance for
that year or for any given quarter within that year. If our quarterly sales or operating results fall below the expectations of investors or securities analysts, the value of our securities could
decline substantially and our business, consolidated results of operations and consolidated financial condition could be materially and adversely affected.

We  have  in  the  past  received  a  warning  letter  and  Form  483  observations  from  the  FDA  which  we  have  recently  resolved.  If  we  receive  any  future  Form  483  observations    or
warning letters, however,   our business, consolidated results of operations and consolidated financial condition could be materially and adversely affected.

We have in the past received a warning letter and Form 483 observations from the FDA regarding certain operations within our manufacturing network.

●

In late May 2011, we received a warning letter from the FDA related to an on-site FDA inspection of our Hayward, California manufacturing facility citing deviations
from current Good Manufacturing Practices (“cGMP”), which are extensive regulations governing manufacturing practices for finished pharmaceutical products and
which establish requirements for manufacturing processes, stability testing, record keeping and quality standards and controls.

● During fiscal years 2012, 2013 and 2014, the FDA conducted cGMP inspections of our Hayward manufacturing facility and during the quarter ended June 30, 2015,

the FDA conducted a cGMP and Pre-Approval Inspection at the facility. At the conclusion of each inspection, we received a Form 483.

●

●

In July 2014, we received a Form 483 after the FDA conducted a cGMP and Pre-Approval Inspection of our Taiwan manufacturing facility.

In March 2015, we received a Form 483 at our Horsham, Pennsylvania operations after the FDA conducted a pharmacovigilance inspection.

During 2015, we successfully resolved the warning letter on our Hayward manufacturing facility and we also received the Establishment Inspection Reports (“EIRs”) for each
of the aforementioned FDA inspections indicating acceptance of our corrective actions and closure by the FDA of each such inspection. Since our receipt of the 2015 notification from
the FDA regarding closure of the warning letter, the FDA has approved a number of products that are manufactured at our Hayward facility.

We remain committed to continuing to improve our quality control and manufacturing practices. We cannot be assured, however, that the FDA will continue to be satisfied
with our corrective actions and with our quality control and manufacturing systems and standards. If we receive any future FDA observations, we may be subject to regulatory action
including,  among  others,  monetary  sanctions  or  penalties,  product  recalls  or  seizure,  injunctions,  total  or  partial  suspension  of  production  and/or  distribution,  and  suspension  or
withdrawal  of  regulatory  approvals.  Further,  other  federal  agencies,  our  customers  and  partners  in  our  alliance,  development,  collaboration  and  other  partnership  agreements  with
respect to our products and services may take any such Form 483 observations or warning letters into account when considering the award of contracts or the continuation or extension
of such partnership  agreements.  If we receive  any future  Form 483 observations  or warning letters from the FDA, our business, consolidated results  of operations and consolidated
financial condition could be materially and adversely affected.

Our continued growth is dependent on our ability to continue to successfully develop and commercialize new products in a timely manner.

Our financial results depend upon our ability to introduce and commercialize additional generic and branded products in a timely manner. In the generic pharmaceutical products
market, revenue from newly launched generic products that we are the first to market is typically relatively high during the period immediately following launch and can be expected
generally  to decline  over time. Revenue from generic  drugs in general  can also be expected  to decline  over time.  Revenue from branded  pharmaceutical  products can be expected  to
decline as the result of entry of new competitors, particularly of companies producing generic versions of the branded products. Our continued growth is therefore dependent upon our
ability to continue to successfully introduce and commercialize new generic and branded products.

As of February 16, 2016, we had 25 product applications pending at the FDA and 18 product candidates under development for generic versions of brand-name pharmaceuticals.
In our branded products division, we have a few product candidates in various stages of development. The development and commercialization process for our products, particularly of
our branded products, is time-consuming, costly and involves a high degree of business risk. The FDA and the regulatory authorities may not approve our products submitted to them or
our other products under development. Additionally, we may not successfully complete our development efforts. Even if the FDA approves our products, we may not be able to market
them successfully or profitably or, with respect to our generics products, we may not be able to market them at all if we do not prevail in the patent infringement litigation in which we are
involved. Our future results of operations will depend significantly upon our ability to timely develop, receive FDA approval for, and market new pharmaceutical products or otherwise
acquire new products.

A substantial portion of our total revenues is derived from sales to a limited number of customers.

We  derive  a  substantial  portion  of  our  revenue  from  sales  to  a  limited  number  of  customers.  In  2015,  our  five  major  customers,  McKesson  Corporation,  Cardinal  Health,

Amerisource-Bergen, CVS Caremark Corporation and N.C. Mutual accounted for 46%, 22%, 19%, 1% and 1%, respectively, or an aggregate of 89%, of our gross revenue.

A reduction in, or loss of business with, any one of these customers, or any failure of a customer to pay us on a timely basis, would adversely affect our business.

A substantial portion of our total revenues is derived from sales of a limited number of products.

We derive  a substantial  portion  of  our revenue  from  sales  of a limited  number  of products.  In 2015, our  top five  products  accounted  for  17%, 12%,  8%, 7% and 6%,  or an
aggregate of 50%, of our product sales, net. The sale of our products can be significantly influenced by market conditions, as well as regulatory actions. We may experience decreases in
the sale of our products in the future as a result of actions taken by our competitors, such as price reductions, or as a result of regulatory actions related to our products or to competing
products, which could have a material impact on our results of operations. Actions which could be taken by our competitors, which may materially and adversely affect our business,
results of operations and financial condition, may include, without limitation, pricing changes and entering or exiting the market for specific products.

Sales of our products may be adversely affected by the continuing consolidation of our customer base.

A  significant  proportion  of  our  sales  is  made  to  relatively  few  retail  drug  chains,  wholesalers,  and  managed  care  organizations.  These  customers  are  continuing  to  undergo
significant consolidation. Such consolidation has provided and may continue to provide them with additional purchasing leverage, and consequently may increase the pricing pressures
that we face. Additionally, the emergence of large buying groups representing independent retail pharmacies, and the prevalence and influence of managed care organizations and similar
institutions, enable those groups to extract price discounts on our products.

Our net sales and quarterly growth comparisons may also be affected by fluctuations in the buying patterns of retail chains, major distributors and other trade buyers, whether
resulting from pricing, wholesaler buying decisions or other factors. In addition, since such a significant portion of our revenues is derived from relatively few customers, any financial
difficulties experienced by a single customer, or any delay in receiving payments from a single customer, could have a material adverse effect on our business, results of operations and
financial condition.

We face intense competition from both brand-name and generic pharmaceutical companies.

The pharmaceutical industry is highly competitive and many of our competitors have longer operating histories and substantially greater financial, research and development,
marketing, and other resources than we have. Further, the pharmaceutical industry has in recent years seen increased consolidation, resulting in larger competitors and placing further
pressure  on  prices,  development  activities  and  customer  retention.  In  addition,  pharmaceutical  manufacturers’  customer  base  consists  of  an  increasingly  limited  number  of  large
pharmaceutical wholesalers, chain drug stores that warehouse products, mass merchandisers and mail order pharmacies. Our competitors may be able to develop products competitive
with or more effective or less expensive than our own for many reasons, including that they may have:

proprietary processes or delivery systems;
●
greater resources in the area of research and development and marketing;
●
●
larger or more efficient production capabilities;
● more expertise in a particular therapeutic area;
● more expertise in preclinical testing and human clinical trials;
● more experience in obtaining required regulatory approvals, including FDA approval;
● more products; or
● more experience in developing new drugs and financial resources, particularly with regard to brand manufacturers.

In the generic products market, we face competition from other generic pharmaceutical companies, which may impact our selling price and revenues from such products. The
FDA approval process often results in the FDA granting final approval to a number of ANDAs for a given product at the time a patent for a corresponding brand product or other market
exclusivity  expires.  This  often  forces  us  to  face  immediate  competition  when  we  introduce  a  generic  product  into  the  market.  As  competition  from  other  generic  pharmaceutical
companies intensifies, selling prices and gross profit margins often decline, which has been our experience with our existing products. Moreover, with respect to products for which we
file a Paragraph IV certification, if we are not the first ANDA filer challenging a listed patent for a product, we are at a significant disadvantage to the competitor that first filed an ANDA
for that product containing such a challenge, which is awarded 180 days of market exclusivity for the product. Conversely, in some cases when we are the first ANDA filer to challenge a
listed  patent,  we  may  forfeit  our  180  days  of  market  exclusivity  under  certain  circumstances.  In  that  case,  a  competitor  may  obtain  ANDA  approval  earlier  than  we  obtain  ANDA
approval, in which case we will be at a disadvantage to such competitor. Accordingly, the level of market share, revenue and gross profit attributable to a particular generic product that
we develop is generally related to the number of competitors in that product’s market and the timing of that product’s regulatory approval and launch, in relation to competing approvals
and launches. Although we cannot assure, we strive to develop and introduce new products in a timely and cost effective manner to be competitive in our industry (see “Item 1 Business
— Regulation”). Additionally, ANDA approvals often continue to be granted for a given product subsequent to the initial launch of the generic product. These circumstances generally
result  in  significantly  lower  prices  and  reduced  margins  for  generic  products  compared  to  brand  products.  New  generic  market  entrants  generally  cause  continued  price  and  margin
erosion over the generic product life cycle.

In addition to the competition we face from other generic pharmaceutical companies related to our generic products, we also face competition from brand-name pharmaceutical
companies  that  may  try  to  prevent,  discourage  or  delay  the  use  of  generic  versions  through  various  measures,  including  introduction  of  new  branded  products,  legislative  initiatives,
changing dosage forms or dosing regimens, regulatory processes, filing new patents or patent extensions, lawsuits, citizens’ petitions, and negative publicity prior to introduction of a
generic product. In addition, brand-name competitors  may lower their prices to compete with generic products, increase advertising, or launch, either through an affiliate or licensing
arrangements  with  another  company,  an  authorized  generic  at  or  near  the  time  the  first  generic  product  is  launched,  reducing  the  generic  product  market  exclusivity  provided  by  the
Hatch-Waxman Act.

Our principal competitors in the generic pharmaceutical products market are Teva Pharmaceutical Industries Ltd., Allergan, Inc., Mylan N.V., Sun Pharmaceutical Industries

Ltd., Lannett Company, Inc., Lupin Pharmaceuticals, Inc., Endo International plc and Sandoz.

In the brand-name pharmaceutical market, our principal competitors are pharmaceutical companies that are focused on Parkinson’s disease and other CNS disorders. In addition,
  with respect to products that we are developing internally and/or any additional products we may in-license from third parties, we expect that we will face increased competition from
large pharmaceutical companies, drug delivery companies and other specialty pharmaceutical companies that have focused on the same disorders as our branded products.

Any of the actions by our competitors as described above may significantly impact sales of our generic and branded products, which could have a material adverse effect on our

business, results of operations and financial condition.

We have experienced operating losses and negative cash flow from operations in the past, and our future profitability is uncertain.

Although we have in recent years been profitable, we do not know whether our business will continue to be profitable or generate positive cash flow, and our ability to remain

profitable or obtain positive cash flow is uncertain. To remain operational and profitable, we must, among other things:

●
●
●
●
●

obtain FDA approval of our products;
successfully launch and market new products;
prevail in patent infringement litigation in which we are involved;
continue to generate or obtain sufficient capital on acceptable terms to fund our operations; and
comply with the many complex governmental regulations that deal with virtually every aspect of our business activities. 

Any delays or unanticipated expenses in connection with the operation of our limited number of facilities could have a material adverse effect on our business.

A substantial portion of our manufacturing capacity as well as our current production is attributable to our manufacturing facilities located in Hayward, California, Middlesex,
New Jersey and Taiwan, R.O.C. and to certain third party suppliers. A significant disruption at any one of these facilities within our internal or third party supply chain, even on a short-
term basis, whether due to an adverse quality or compliance observation, including a total or partial suspension of production and/or distribution by regulatory authorities, an act of God,
civil or political unrest, or other events could impair our ability to produce and ship products to the market on a timely basis and could, among other consequences, subject us to exposure
to claims from customers. Any of these events could have a material adverse effect on our business, results of operations and financial condition.

Our business is subject to the economic, political, legal and other risks of maintaining facilities and conducting clinical trials in foreign countries.

In 2010, we commenced shipment of commercial product from our new manufacturing facility in Taiwan, and we plan to increase our commercial manufacturing operations in
Taiwan  in  the  future.  In  addition,  certain  clinical  trials  for  our  product  candidates  are  conducted  at  multiple  sites  in  Europe.  These  foreign  operations  are  subject  to  risks  inherent  in
maintaining  operations  and  doing  business  abroad,  such  as  economic  and  political  destabilization,  international  conflicts,  restrictive  actions  by  foreign  governments,  expropriation  or
nationalization of property, changes in laws and regulations, changes in regulatory requirements, the difficulty of effectively managing diverse global operations, adverse foreign tax or
tariff laws, more limited intellectual property protection in certain foreign jurisdictions, and the threat posed by potential international disease pandemics in countries that do not have the
resources necessary to deal with such outbreaks. Further, as our global operations require compliance with a complex set of foreign and U.S. laws and regulations, including data privacy
requirements, labor relations laws, tax laws, anti-competition regulations, import and trade restrictions, export requirements, U.S. laws such as the Foreign Corrupt Practices Act of 1977,
as  amended,  and  local  laws  which  also  prohibit  payments  to  governmental  officials  or  certain  payments  or  remunerations  to  customers,  there  is  a  risk  that  some  provisions  may  be
inadvertently breached. Violations of these laws and regulations could result in fines, criminal sanctions against us, our officers or our employees, and prohibitions on the conduct of our
business. These foreign economic, political, legal and other risks could impact our operations and have an adverse effect on our business, results of operations and financial condition.

We are involved in various legal proceedings, including patent litigation that can delay or prevent our commercialization of generic products or accelerate generic competition for
our branded products, all of which are uncertain, force us to incur substantial expense to defend and/or expose us to substantial liability.

Patent infringement litigation involves many complex technical and legal issues and its outcome is often difficult to predict, and the risk involved in doing so can be substantial.
For generic product manufacturers, the potential consequences to such generic companies in the event of an unfavorable outcome include delaying generic launch until patent expiration
and  potential  damages  measured  by  the  profits  lost  by  the  branded  product  manufacturer  rather  than  the  profits  earned  by  the  generic  pharmaceutical  company.    For  brand  drug
manufacturers, an unfavorable outcome may significantly accelerate generic competition ahead of patent expiration. Such litigation usually involves significant expense and can delay or
prevent introduction or sale of our products. Our generic products division is routinely subject to patent infringement litigation brought by branded pharmaceutical manufacturers seeking
to delay FDA approval to manufacture and market generic forms of their branded products. Likewise, our branded products division is currently involved in patent infringement litigation
against generic drug manufacturers seeking FDA approval to market their generic drugs prior to expiration of patents covering our branded products.

We and/or our third party partners are routinely subject to patent infringement suits related to our Generics Division products, including as of February 16, 2016, one related to
oxymorphone hydrochloride tablets. If this or any of our future patent litigation matters involving generic products are resolved unfavorably, we or our alliance or collaboration partners
may be enjoined from manufacturing, developing or selling the generic product that is the subject of such litigation without a license from the other party. In addition, if we decide to
market and sell generic products prior to the resolution of patent infringement suits, we could be held liable for lost profits if we are found to have infringed a valid patent, or liable for
treble damages if we are found to have willfully infringed a valid patent. In our branded products division, as of February 16, 2016, we were involved in two patent infringement suits,
one related to Zomig  nasal spray and the other related to Rytary 
. If these patent litigation matters involving our branded products are resolved unfavorably, our Zomig  nasal spray
product  and/or  Rytary  may  face  generic  competition  significantly  earlier  than  the  date  of  patent  expirations  for  the  products.  We  have  incurred  substantial  expense  to  defend  the
foregoing patent litigation suits; during fiscal year 2015, we incurred costs of approximately $4.6 million in connection with our participation in the patent litigation matters described
above, as well as for other matters that were resolved in 2015. Although it is not currently possible to quantify the liability we could incur if any of the above referenced patent litigation
suits are decided against us, any unfavorable outcome on such matters could have a material adverse effect on our business, results of operations and financial condition.

In addition to patent infringement litigation claims, we are or may become a party to other litigation in the ordinary course of our business, including, among others, matters
alleging product liability, other intellectual property rights infringement, violations of securities laws, employment discrimination or breach of commercial contract. A detailed description
of our significant legal proceedings are described in “Item 15. Exhibits and Financial Statement Schedules – Note 22. Legal and Regulatory Matters.” In general, litigation claims can be
expensive and time consuming to bring or defend against and could result in settlements or damages that could have a material adverse effect on our business, results of operations and
financial condition.

Our agreements with brand pharmaceutical companies, which are important to our business, are facing increased government scrutiny in the United States, which may result in
increased government actions and private litigation suits.

We  are  involved  in  numerous  patent  litigations  in  which  we  challenge  the  validity  or  enforceability  of  innovator  companies’  listed  patents  and/or  their  applicability  to  our
generic pharmaceutical products, as well as patent infringement litigation in which generic companies challenge the validity or enforceability of our patents and/or their applicability to
their  generic  pharmaceutical  products,  and  therefore  settling  patent  litigations  has  been  and  is  likely  to  continue  to  be  an  important  part  of  our  business.  Parties  to  such  settlement
agreements in the United States, including us, are required by law to file them with the Federal Trade Commission (“FTC”) and the Antitrust Division of the Department of Justice for
review. The FTC has publicly stated that, in its view, some of the brand - generic settlement agreements violate the antitrust laws and has brought actions against some brand and generic
companies that have entered into such agreements. In June 2013, the U.S. Supreme Court in its decision in  FTC v. Actavis  determined that “reverse payment” settlement agreements
between brand and generic companies could violate antitrust laws. The Supreme Court held that such settlement agreements are neither immune from antitrust attack nor presumptively
illegal but rather should be analyzed under the “Rule of Reason.” It is currently uncertain the effect the Supreme Court’s decision will have on our existing settlement agreements or its
impact on our ability to enter into such settlement agreements in the future or the terms thereof. The Supreme Court’s decision may result in heightened scrutiny from the FTC of such
settlement agreements and we may become subject to increased FTC investigations or enforcement actions arising from such settlement agreements. Further, private plaintiffs, including
direct  and  indirect  purchasers  of  our  products,  may  also  become  more  active  in  bringing  private  litigation  claims  against  us  and  other  brand  and  generic  pharmaceutical  companies
alleging that such settlement agreements violate antitrust laws.

21

 
 
 
   
 
 
 
  
 
In May 2012, we received a Civil Investigative Demand (“CID”) from the FTC concerning its investigation into the drug SOLODYN 

and its generic equivalents. According
to the FTC, the investigation was to determine whether we, along with Medicis Pharmaceutical Corporation (now a wholly owned subsidiary of Valeant Pharmaceuticals International,
Inc.) and six other companies, had engaged or were engaged in unfair methods of competition in or affecting commerce by entering into agreements regarding SOLODYN  or its generic
® 
equivalents and/or engaging in other conduct regarding the sale or marketing of SOLODYN  or its generic equivalents. On November 6, 2015, the FTC issued a letter to us indicting that
it had closed its investigation of the SOLODYN  agreements with no further action by the FTC. In February 2014, we received a CID from the FTC concerning its investigation into the
drug  Opana®  ER  and  its  generic  equivalents.  According  to  the  FTC,  the  investigation  relates  to  whether  we  and  Endo  Pharmaceuticals,  Inc.  have  engaged  or  are  engaged  in  unfair
methods of competition in or affecting commerce by (i) entering into agreements regarding Opana  ER or its generic equivalents and/or (ii) engaging in other conduct regarding the
regulatory filings, sale or marketing of Opana  ER or its generic equivalents. The FTC’s investigation related to Opana  ER currently remains open. To our knowledge, no proceedings
® 
by the FTC have been initiated against us at this time in the FTC’s investigation into Opana  ER; however, no assurance can be given as to the timing or outcome of such investigation.

® 

® 

® 

® 

® 

®  

Private plaintiffs have also filed class action complaints against us and other manufacturers of SOLODYN 

, Opana  ER and their respective generic equivalents. A detailed
description of the SOLODYN  and Opana  ER FTC investigations and class action suits are described in “Item 15. Exhibits and Financial Statement Schedules – Note 22. Legal and
Regulatory Matters.” The defense of antitrust litigation investigation and claims are generally expensive and time consuming, and we can give no assurance as to the timing or outcome of
such investigation or claims or of any future private litigation or government action alleging that one of our settlement agreements violates antitrust laws.

Our ability to develop or license, or otherwise acquire, and introduce new products on a timely basis in relation to our competitors’ product introductions involves inherent risks and
uncertainties.

Product development is inherently risky, especially for new drugs for which safety and efficacy have not been established and the market is not yet proven. Likewise, product
licensing involves inherent risks including uncertainties due to matters that may affect the achievement of milestones, as well as the possibility of contractual disagreements with regard to
terms  such  as  license  scope  or  termination  rights.  The  development  and  commercialization  process,  particularly  with  regard  to  new  drugs,  also  requires  substantial  time,  effort  and
financial resources. The process of obtaining FDA approval to manufacture and market new pharmaceutical products is rigorous, time consuming, costly and largely unpredictable. We,
or a partner, may not be successful in obtaining FDA approval or in commercializing any of the products that we are developing or licensing.

Our approved products may not achieve expected levels of market acceptance.

Even if we are able to obtain regulatory approvals for our new products, the success of those products is dependent upon market acceptance. Levels of market acceptance for our

new products could be affected by several factors, including:

●
●
●
●
●

●

the availability of alternative products from our competitors;
the prices of our products relative to those of our competitors;
the timing of our market entry;
the ability to market our products effectively at the retail level;
the perception of patients and the healthcare community, including third-party payers, regarding the safety, efficacy and benefits of our drug products compared to those of
competing products; and
the acceptance of our products by government and private formularies.

Some of these factors are not within our control, and our products may not achieve expected levels of market acceptance. Additionally, continuing and increasingly sophisticated
studies of the proper utilization, safety and efficacy of pharmaceutical products are being conducted by the industry, government agencies and others which can call into question the
utilization, safety and efficacy of previously marketed products. In some cases, studies have resulted, and may in the future result, in the discontinuance of product marketing or other risk
management programs such as the need for a patient registry.

22

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Our business is highly dependent on market perceptions of us and the safety and quality of our products. Our business or products could be subject to negative publicity, which could
have a material adverse effect on our business, results of operations and financial condition.

Market perceptions of our business are very important to us, especially market perceptions of the safety and quality of our products. If any of our products or similar products
that other companies distribute are subject to market withdrawal or recall or are proven to be, or are claimed to be, harmful to consumers, then this could have a material adverse effect on
our business, results of operations and financial condition. Also, because our business is dependent on market perceptions, negative publicity associated with product quality, illness or
other adverse effects resulting from, or perceived to be resulting from, our products could have a material adverse impact on our business, results of operations and financial condition.

We may discontinue the manufacture and distribution of certain existing products, which may adversely impact our business, results of operations and financial condition.

We  continually  evaluate  the  performance  of  our  products,  and  may  determine  that  it  is  in  our  best  interest  to  discontinue  the  manufacture  and  distribution  of  certain  of  our
products. We cannot guarantee that we have correctly forecasted, or will correctly forecast in the future, the appropriate products to discontinue or that our decision to discontinue various
products is prudent if market conditions change. In addition, we cannot assure you that the discontinuance of products will reduce our operating expenses or will not cause us to incur
material charges associated with such a decision. Furthermore, the discontinuance of existing products entails various risks, including, in the event that we decide to sell the discontinued
product, the risk that we will not be able to find a purchaser for such products or that the purchase price obtained will not be equal to at least the book value of the net assets for such
products.  Other  risks  include  managing  the  expectations  of,  and  maintaining  good  relations  with,  our  customers  who  previously  purchased  products  from  our  discontinued  products,
which could prevent us from selling other products to them in the future. Moreover, we may incur other significant liabilities and costs associated with our discontinuance of products,
which could have a material adverse effect on our business, results of operations and financial condition.

We  expend  a  significant  amount  of  resources  on  research  and  development  efforts  that  may  not  lead  to  successful  product  introductions  or  the  recovery  of  our  research  and
development expenditures.

We conduct research and development primarily to enable us to manufacture and market pharmaceuticals in accordance with FDA regulations. We spent approximately $77.0
million, $78.6 million and $68.9 million on research and development activities during the years ended December 31, 2015, 2014 and 2013, respectively. We are required to obtain FDA
approval before marketing our drug products. The FDA approval process is costly and time consuming. Typically, research expenses related to the development of innovative products
and  the  filing  of  NDAs  are  significantly  greater  than  those  expenses  associated  with  ANDAs.  As  we  continue  to  develop  new  products,  our  research  expenses  will  likely  increase.
Because of the inherent risk associated with research and development efforts in our industry, our research and development expenditures may not result in the successful introduction of
FDA-approved pharmaceuticals.

Our bioequivalence studies, other clinical studies and/or other data may not result in FDA approval to market our new drug products. While we believe that the FDA’s ANDA
procedures will apply to our bioequivalent versions of branded drugs, these drugs may not be suitable for, or approved as part of, these abbreviated applications. In addition, even if our
drug products are suitable for FDA approval by filing an ANDA, the abbreviated applications are costly and time consuming to complete. After we submit an NDA or ANDA, the FDA
may require that we conduct additional studies, and as a result, we may be unable to reasonably determine the total research and development costs to develop a particular product. Also,
for products pending approval, we may obtain raw materials or produce batches of inventory to be used in anticipation of the product’s launch. In the event that FDA approval is denied
or  delayed,  we  could  be  exposed  to  the  risk  of  this  inventory  becoming  obsolete.  Finally,  we  cannot  be  certain  that  any  investment  made  in  developing  products  or  product-delivery
technologies will be recovered, even if we are successful in commercialization. To the extent that we expend significant resources on research and development efforts and are not able,
ultimately, to introduce successful new products or new delivery technologies as a result of those efforts, we will be unable to recover those expenditures.

The time necessary to develop generic drugs may adversely affect whether, and the extent to which, we receive a return on our capital.

We generally begin our development activities for a new generic drug product several years in advance of the patent expiration date of the brand-name drug equivalent. The
development process, including drug formulation, testing, and FDA review and approval, often takes three or more years. This process requires that we expend considerable capital to
pursue activities that do not yield an immediate or near-term return. Also, because of the significant time necessary to develop a product, the actual market for a product at the time it is
available for sale may be significantly less than the originally projected market for the product. If this were to occur, our potential return on our investment in developing the product, if
approved for marketing by the FDA, would be adversely affected and we may never receive a return on our investment in the product. It is also possible for the manufacturer of the brand-
name product for which we are developing a generic drug to obtain approvals from the FDA to switch the brand-name drug from the prescription market to the OTC market. If this were
to occur, we would be prohibited from marketing our product other than as an OTC drug, in which case revenues could be substantially less than we anticipated.

Research and development efforts invested in our branded pharmaceutical products may not achieve expected results.

We invest increasingly significant resources to develop our branded products, both through our own efforts and through collaborations, in-licensing and acquisition of products
from  or  with  third  parties.  The  development  of  proprietary  branded  drugs  involves  processes  and  expertise  different  from  those  used  in  the  development  of  generic  products,  which
increases the risks of failure that we face. For example, the time from discovery to commercial launch of a branded product can be 15 years or even longer, and involves multiple stages:
not only  intensive  preclinical  and clinical  testing,  but  also highly  complex,  lengthy  and expensive  approval  processes  which can  vary  from  country  to  country.  The  longer  it  takes  to
develop a product, the longer time it may take for us to recover our development costs and generate profits, if at all.

During each development stage, we may encounter obstacles that delay the process or approval and increase expenses, leading to significant risks that we will not achieve our
goals and may be forced to abandon a potential product in which we have invested substantial amounts of time and money. These obstacles may include: preclinical failures; difficulty
enrolling  patients  in clinical  trials;  delays  in completing  formulation  and other  work needed to support an application  for  approval;  adverse  reactions  or other  safety  concerns  arising
during  clinical  testing;  insufficient  clinical  trial  data  to  support  the  safety  or  efficacy  of  the  product  candidate;  and  failure  to  obtain,  or  delays  in  obtaining,  the  required  regulatory
approvals for the product candidate or the facilities in which it is manufactured. For instance, during 2013, we discontinued our branded pharmaceutical development programs for the
potential  treatment  of  moderate  to  severe  Restless  Leg  Syndrome  (“RLS”)  after  the  results  from  the  study  did  not  achieve  the  statistical  criteria  for  its  primary  efficacy  endpoints
compared to placebo and our program for the potential treatment of epilepsy as a result of technical and competitive factors. As a result of the obstacles noted above, our investment in
research and development of branded products can involve significant costs with no assurances of future revenues or profits.

Approvals for our new generic drug products may be delayed or become more difficult to obtain if the FDA institutes changes to its approval requirements.  

The FDA may institute changes to its ANDA approval requirements, which may make it more difficult or expensive for us to obtain approval for our new generic products. For
instance, in July 2012, the Generic Drug Fee User Amendments of 2012 (“GDUFA”) was enacted into law. The GDUFA legislation implemented fees for new ANDAs, Drug Master
Files, product and establishment fees and a one-time fee for back-logged ANDAs pending approval as of October 1, 2012. In return, the program is intended to provide faster and more
predictable ANDA reviews by the FDA and increased inspections of drug facilities. Under GDUFA, generic product companies face significant penalties for failure to pay the new user
fees, including rendering an ANDA not “substantially complete” until the fee is paid. Any failure by us or our suppliers to pay the fees or to comply with the other provisions of GDFUA
may impact or delay our ability to file ANDAs, obtain approvals for new generic products, generate revenues and thus may have a material adverse effect on our business, results of
operations and financial condition.

In addition to the implementation  of new fees and review procedures  by the FDA, the FDA may also implement  other changes that may directly  affect  some of our ANDA
filings pending approval from the FDA, such as changes to guidance from the FDA regarding bioequivalency requirements for particular drugs. Such changes may cause our development
of  such  generic  drugs  to  be  significantly  more  difficult  or  result  in  delays  in  FDA  approval  or  result  in  our  decision  to  abandon  or  terminate  certain  projects.  Any  changes  in  FDA
requirements may make it more difficult for us to file ANDAs or obtain approval of our ANDAs and generate revenues and thus have a material adverse effect on our business, results of
operations and financial condition.

The risks and uncertainties inherent in conducting clinical trials could delay or prevent the development and commercialization of our own branded products, which could have a
material adverse effect on our business, results of operations and financial condition.

With respect to our branded products which do not qualify for the FDA’s abbreviated application procedures, we must demonstrate through clinical trials that these products are
safe and effective for use. We have only limited experience in conducting and supervising clinical trials. The process of completing clinical trials and preparing an NDA may take several
years and requires substantial resources. Our studies and filings may not result in FDA approval to market our new drug products and, if the FDA grants approval, we cannot predict the
timing of any approval. There are substantial filing fees for NDAs that are not refundable if FDA approval is not obtained.

There are a number of risks and uncertainties associated with clinical trials. The results of clinical trials may not be indicative of results that would be obtained from large scale
testing. Clinical trials are often conducted with patients having advanced stages of disease and, as a result, during the course of treatment these patients can die or suffer adverse medical
effects for reasons that may not be related to the pharmaceutical agents being tested, but which nevertheless affect the clinical trial results. In addition, side effects experienced by the
patients may cause delay of approval or limit the profile of an approved product. Moreover, our clinical trials may not demonstrate sufficient safety and efficacy to obtain approval from
the FDA or foreign regulatory authorities. The FDA or foreign regulatory authorities may not agree with our assessment of the clinical data or they may interpret it differently. Such
regulatory authorities may require additional or expanded clinical trials. Even if the FDA or foreign regulatory authorities approve certain products developed by us, there is no assurance
that such regulatory authorities will not subject marketing of such products to certain limits on indicated use.

Failure can occur at any time during the clinical trial process and, in addition, the results from early clinical trials may not be predictive of results obtained in later and larger
clinical trials, and product candidates in later clinical trials may fail to show the desired safety or efficacy despite having progressed successfully through earlier clinical testing. A number
of companies in the pharmaceutical  industry, including us, have suffered significant setbacks in clinical trials, even in advanced clinical trials after showing positive results in earlier
clinical  trials.  For  example,  we  had  previously  sought  to  develop  an  earlier  product  formulation  containing  carbidopa/levodopa  for  the  treatment  of  Parkinson’s  disease.  Following
completion of the clinical trials and submission of the NDA, the NDA was not approved due to the FDA’s concerns over product nomenclature and the potential for medication errors. In
early 2013, we discontinued our branded pharmaceutical development program for IPX159, an oral controlled-release formulation for the potential treatment of moderate to severe RLS,
after the results from the clinical study in patients did not achieve the statistical criteria for its primary efficacy endpoints compared to placebo. In the future, the completion of clinical
trials for our product candidates may be delayed or halted for the reasons noted above in addition to many other reasons, including:

●
●
●
●
●
●
●
●
●
●
●

delays in patient enrollment, and variability in the number and types of patients available for clinical trials;
regulators or institutional review boards may not allow us to commence or continue a clinical trial;
our inability, or the inability of our partners, to manufacture or obtain from third parties materials sufficient to complete our clinical trials;
delays or failure in reaching agreement on acceptable clinical trial contracts or clinical trial protocols with prospective clinical trial sites;
risks associated with trial design, which may result in a failure of the trial to show statistically significant results even if the product candidate is effective;
difficulty in maintaining contact with patients after treatment commences, resulting in incomplete data;
poor effectiveness of product candidates during clinical trials;
safety issues, including adverse events associated with product candidates;
the failure of patients to complete clinical trials due to adverse side effects, dissatisfaction with the product candidate, or other reasons;
governmental or regulatory delays or changes in regulatory requirements, policy and guidelines; and
varying interpretation of data by the FDA or foreign regulatory authorities.

In addition, our product candidates could be subject to competition for clinical study sites and patients from other therapies under development which may delay the enrollment

in or initiation of our clinical trials.

The FDA or foreign regulatory authorities may require us to conduct unanticipated additional clinical trials, which could result in additional expense and delays in bringing our
product candidates to market. Any failure or delay in completing clinical trials for our product candidates would prevent or delay the commercialization of our product candidates. We
cannot  assure  that  our  expenses  related  to  clinical  trials  will  lead  to  the  development  of  brand-name  drugs  that  will  generate  revenues  in  the  near  future.  Delays  or  failure  in  the
development and commercialization of our own branded products could have a material adverse effect on our business, results of operations and financial condition.

We rely on third parties to conduct clinical trials and testing for our product candidates, and if they do not properly and successfully perform their legal and regulatory obligations,
as well as their contractual obligations to us, we may not be able to obtain regulatory approvals for our product candidates. 

We design the clinical trials for our product candidates, but rely on contract research organizations and other third parties to assist us in managing, monitoring and otherwise
carrying out these trials, including with respect to site selection, contract negotiation, analytical testing and data management. We do not control these third parties and, as a result, they
may not treat our clinical studies as their highest priority, or in the manner in which we would prefer, which could result in delays.

Although we rely on third parties to conduct our clinical trials and related activities, we are responsible for confirming that each of our clinical trials is conducted in accordance
with our general investigational plan and protocol. Moreover, the FDA and foreign regulatory agencies require us to comply with regulations and standards, commonly referred to as good
clinical practices and good laboratory practices, for conducting, recording and reporting the results of clinical trials to ensure that the data and results are credible and accurate and that the
trial participants are adequately protected. Our reliance on third parties does not relieve us of these responsibilities and requirements. The FDA enforces good clinical practices and good
laboratory practices through periodic inspections of trial sponsors, principal investigators and trial sites. If we, our contract research organizations or our study sites fail to comply with
applicable  good  clinical  practices  and  good  laboratory  practices,  the  clinical  data  generated  in  our  clinical  trials  may  be  deemed  unreliable  and  the  FDA  may  require  us  to  perform
additional clinical trials before approving our marketing applications. We cannot assure you that, upon inspection, the FDA will determine that any of our clinical trials comply with good
clinical practices and good laboratory practices. In addition, our clinical trials must be conducted with product manufactured under the FDA’s current Good Manufacturing Practices, or
cGMP, regulations. Our failure or the failure of our contract manufacturers if any are involved in the process, to comply with these regulations may require us to repeat clinical trials,
which would delay the regulatory approval process.

If third parties do not successfully carry out their duties under their agreements with us, if the quality or accuracy of the data they obtain is compromised due to failure to adhere
to our clinical protocols or regulatory requirements, or if they otherwise fail to comply with clinical trial protocols or meet expected deadlines, our clinical trials may not meet regulatory
requirements. If our clinical trials do not meet regulatory requirements or if these third parties need to be replaced, our clinical trials may be extended, delayed, suspended or terminated.
If any of these events occur, we may not be able to obtain regulatory approval of our product candidates, which could have a material adverse effect on our business, results of operations
and financial condition.

We currently do not have a license partner for commercialization of NUMIENT™ outside of the United States.

™ 

In November 2015, the European Commission granted marketing authorization for NUMIENT 

in the United States).  The review of the
NUMIENT 
application was conducted under the centralized licensing procedure as a therapeutic innovation, and the authorization is applicable in all 28 member states of the European
Union, as well as Iceland, Liechtenstein and Norway. To date, we have not launched commercialization activities for NUMIENT™ outside of the United States and we do not currently
have a license partner for the commercialization of the product outside of the United States. We previously were a party to a License, Development and Commercialization Agreement
with Glaxo Group Limited (“GSK”) dated December 15, 2010 whereby GSK received an exclusive license to develop and commercialize IPX066 throughout the world, except in the
United States and Taiwan, and certain follow-on products at the option of GSK. The License, Development and Commercialization Agreement with GSK was subsequently terminated
and GSK’s rights to develop and commercialize  the product outside the United States and Taiwan were transferred back to us in 2013. We are currently engaged in discussions with
outside of the United States; however, no assurances can be made that we will find such a partner. If we are unsuccessful in entering into such
potential partners to market NUMIENT 
third party collaboration arrangements for ex-United States commercialization activities of NUMIENT 
, such failure could have a material adverse effect on our business, results of
operations and financial condition.

The illegal distribution and sale by third parties of counterfeit versions of our products or of stolen products could have a negative impact on our reputation and a material adverse
effect on our business, results of operations and financial condition.

Third  parties  could  illegally  distribute  and  sell  counterfeit  versions  of  our  products,  which  do  not  meet  the  rigorous  manufacturing  and  testing  standards  that  our  products
undergo.  Counterfeit  products  are  frequently  unsafe  or  ineffective,  and  can  be  life-threatening.  Counterfeit  medicines  may  contain  harmful  substances,  the  wrong  dose  of  the  active
pharmaceutical  ingredient  or no active pharmaceutical  ingredients at all. However, to distributors and users, counterfeit  products may be visually indistinguishable  from the authentic
version.

Reports  of  adverse  reactions  to  counterfeit  drugs  or  increased  levels  of  counterfeiting  could  materially  affect  patient  confidence  in  the  authentic  product.  It  is  possible  that
adverse events caused by unsafe counterfeit products will mistakenly be attributed to the authentic product. In addition, thefts of inventory at warehouses, plants or while in-transit, which
are not properly stored and which are sold through unauthorized channels could adversely impact patient safety, our reputation and our business. 

Public  loss  of  confidence  in  the  integrity  of  pharmaceutical  products  as  a  result  of  counterfeiting  or  theft  could  have  a  material  adverse  effect  on  our  business,  results  of

operations and financial condition.

We  are  dependent  on  a  small  number  of  suppliers  for  our  raw  materials  that  we  use  to  manufacture  our  products  and  interruptions  in  our  supply  chain  could  materially  and
adversely affect our business.

We typically purchase the ingredients, other materials and supplies that we use in the manufacturing of our products, as well as certain finished products, from a small number of
foreign and domestic suppliers. The FDA requires identification of raw material suppliers in applications for approval of drug products. If raw materials were unavailable from a specified
supplier or the supplier was not in compliance with FDA or other applicable requirements, the FDA approval of a new supplier could delay the manufacture of the drug involved. As a
result, there is no guarantee we will always have timely and sufficient access to a required raw material or other product. In addition, some materials used in our products are currently
available from only one supplier or a limited number of suppliers. Generally, we would need as long as 18 months to find and qualify a new sole-source supplier. If we receive less than
one year’s termination notice from a sole-source supplier that it intends to cease supplying raw materials, it could result in disruption of our ability to produce the drug involved. Further,
a significant portion of our raw materials may be available only from foreign sources. Foreign sources can be subject to the special risks of doing business abroad, including:

●
●
●

●

greater possibility for disruption due to transportation or communication problems;
the relative instability of some foreign governments and economies;
interim price volatility based on labor unrest, materials or equipment shortages, export duties, restrictions on the transfer of funds, or fluctuations in currency exchange
rates; and
uncertainty regarding recourse to a dependable legal system for the enforcement of contracts and other rights.

Those  of  our  raw  materials  that  are  available  from  a  limited  number  of  suppliers  include  Bendroflumethiazide,  Chloroquine  Phosphate,  Colestipol,  Digoxin,  Fenofibrate,
Methyltestosterone,  Nadolol  and  Pyridostigmin,  all  of  which  are  active  pharmaceutical  ingredients.  The  manufacturers  of  several  of  these  products  are  sole-source  suppliers.  Only  a
couple of our active ingredients are covered by long-term supply agreements and, although we have to date only experienced occasional interruptions in supplies, we cannot assure you
that we will continue to receive uninterrupted or adequate supplies of such raw materials.

Many third-party suppliers are subject to governmental regulation and, accordingly, we are dependent on the regulatory compliance of these third parties. We also depend on the
strength, enforceability and terms of our various contracts with these third-party suppliers. We also rely on complex shipping arrangements throughout the various facilities of our supply
chain spectrum. Customs clearance and shipping by land, air or sea routes rely on and may be affected by factors that are not in our full control or are hard to predict.

Any inability to obtain raw materials on a timely basis, or any significant price increases which cannot be passed on to customers, could have a material adverse effect on our

business, results of operations and financial condition.

Our policies regarding returns, rebates, allowances and chargebacks, and marketing programs adopted by wholesalers may reduce our revenues in future fiscal periods.

Based  on  industry  practice,  generic  drug  manufacturers  have  liberal  return  policies  and  have  been  willing  to  give  customers  post-sale  inventory  allowances.  Under  these
arrangements,  from  time  to  time,  we  give  our  customers  credits  on  our  generic  products  that  our  customers  hold  in  inventory  after  we  have  decreased  the  market  prices  of  the  same
generic products due to competitive pricing. Therefore, if new competitors enter the marketplace and significantly lower the prices of any of their competing products, we would likely
reduce  the  price  of  our  product.  As  a  result,  we  would be  obligated  to  provide  credits  to  our  customers  who are  then  holding  inventories  of  such  products,  which  could  reduce  sales
revenue and gross margin for the period the credit is provided. Like our competitors, we also give credits for chargebacks to wholesalers that have contracts with us for their sales to
hospitals, group purchasing organizations, pharmacies or other customers. A chargeback is the difference between the price the wholesaler pays and the price that the wholesaler’s end-
customer pays for a product. Although we establish reserves based on our prior experience and our best estimates of the impact that these policies may have in subsequent periods, we
cannot ensure that our reserves are adequate or that actual product returns, rebates, allowances and chargebacks will not exceed our estimates.

Certain of our products use controlled substances, the availability of which may be limited by the DEA and other regulatory agencies.

We utilize controlled substances in certain of our current products and products in development and therefore must meet the requirements of the Controlled Substances Act of
1970 and the related regulations administered by the DEA in the United States. These laws relate to the manufacture, shipment, storage, sale and use of controlled substances. The DEA
and other regulatory agencies limit the availability of the active ingredients used in certain of our current products and products in development and, as a result, our procurement quota of
these active ingredients may not be sufficient to meet commercial demand or complete clinical trials. We must annually apply to the DEA for procurement quota in order to obtain these
substances. Any delay or refusal by the DEA in establishing our procurement quota for controlled substances could delay or stop our clinical trials or product launches, or could cause
trade inventory disruptions for those products that have already been launched, which could have a material adverse effect on our business, results of operations and financial condition.

Unstable economic conditions may adversely affect our industry, business, results of operations and financial condition.

The  global  economy  has  undergone  a  period  of  significant  volatility  which  has  led  to  diminished  credit  availability,  declines  in  consumer  confidence  and  increases  in
unemployment  rates.  There  remains  caution  about  the  stability  of  the  U.S.  economy,  and  we  cannot  assure  that  further  deterioration  in  the  financial  markets  will  not  occur.  These
economic conditions have resulted in, and could lead to further, reduced consumer spending related to healthcare in general and pharmaceutical products in particular.

In addition, we have exposure to many different industries and counterparties, including our partners under our alliance and collaboration agreements, suppliers of raw chemical
materials,  drug wholesalers  and other  customers  that  may be affected  by an unstable  economic  environment.  Any economic  instability  may  affect  these  parties’  ability  to fulfill  their
respective contractual obligations to us, cause them to limit or place burdensome conditions upon future transactions with us or drive us and our competitors to decrease prices, each of
which could materially and adversely affect our business, results of operations and financial condition.

Furthermore, the capital and credit markets have experienced extreme volatility. Disruptions in the credit markets make it harder and more expensive to obtain funding. In the
event current resources do not satisfy our needs, we may have to seek additional financing. The availability of additional financing will depend on a variety of factors such as market
conditions and the general availability of credit. Future debt financing may not be available to us when required or may not be available on acceptable terms, and as a result we may be
unable to grow our business, take advantage of business opportunities, or respond to competitive pressures.

We may be subject to disruptions or failures in our information technology systems and network infrastructures that could have a material adverse effect on our business.

We  rely  on  the  efficient  and  uninterrupted  operation  of  complex  information  technology  systems  and  network  infrastructures  to  operate  our  business.  We  also  hold  data  in
various data center facilities upon which our business depends. A disruption, infiltration or failure of our information technology systems or any of our data centers as a result of software
or hardware malfunctions, system implementations or upgrades, computer viruses, third-party security breaches, employee error, theft or misuse, malfeasance, power disruptions, natural
disasters or accidents could cause breaches of data security, loss of intellectual property and critical data and the release and misappropriation of sensitive competitive information. Any
of these events could result in the loss of key information, impair our production and supply chain processes, harm our competitive position, cause us to incur significant costs to remedy
any damages and ultimately materially and adversely affect our business, results of operations and financial condition.

28

 
 
 
 
 
 
 
 
 
   
 
 
 
While we have implemented a number of protective measures, including firewalls, antivirus, patches, data encryption, log monitors, routine back-ups with offsite retention of
storage media, system audits, data partitioning, routine password modifications and disaster recovery procedures, such measures may not be adequate or implemented properly to prevent
or fully address the adverse effect of such events.

We may be adversely affected by alliance, collaboration, supply, or license and distribution agreements we enter into with other companies.

We have entered into several alliance, collaboration, supply or license and distribution agreements with respect to certain of our products and services and may enter into similar
agreements in the future. These arrangements may require us to relinquish rights to certain of our technologies or product candidates, or to grant licenses on terms that ultimately may
prove  to  be  unfavorable  to  us.  Relationships  with  alliance  partners  may  also  include  risks  due  to  regulatory  requirements,  incomplete  marketplace  information,  inventories,  and
commercial strategies of our partners, and our agreements may be the subject of contractual disputes. If we or our partners are not successful in commercializing the products covered by
the agreements, such commercial failure could adversely affect our business.

Pursuant to license and distribution agreements with unrelated third party pharmaceutical companies, we are dependent on such companies to supply us with product that we
market and sell, and we may enter into similar agreements in the future. Any delay or interruption in the supply of product under such agreements could curtail or delay our product
shipment and adversely affect our revenues, as well as jeopardize our relationships with our customers.

From time to time we may need to rely on licenses to proprietary technologies, which may be difficult or expensive to obtain.

We may need to obtain licenses to patents and other proprietary rights held by third parties to develop, manufacture and market products. If we are unable to timely obtain these
licenses on commercially reasonable terms, our ability to commercially market our products may be inhibited or prevented, which could have a material adverse effect on our business,
results of operations and financial condition.

We depend on qualified scientific and technical employees and are increasingly dependent on our direct sales force, and our limited resources may make it more difficult to attract
and retain these personnel.

Because of the specialized scientific nature of our business, we are highly dependent upon our ability to continue to attract and retain qualified scientific and technical personnel.
We are not aware of any pending, significant  losses of scientific  or technical  personnel.  Loss of the services  of, or failure  to recruit,  key scientific  and technical  personnel, however,
would be significantly detrimental to our product-development programs. As a result of our small size and limited financial and other resources, it may be difficult for us to attract and
retain qualified officers and qualified scientific and technical personnel.

In addition, marketing of our branded products, such as the Zomig® products pursuant to our AZ Agreement with AstraZeneca and Rytary 

, requires much greater use of a
direct sales force compared to marketing of our generic products. Our ability to realize significant revenues from marketing and sales activities depends on our ability to attract and retain
qualified sales personnel. Competition for qualified sales personnel is intense. Any failure to attract or retain qualified sales personnel could negatively impact our sales revenue and have
a material adverse effect on our business, results of operations and financial condition.

® 

We have entered into employment agreements with our executive officers and certain other key employees. Under the employment agreements, the employee may terminate his
or her employment upon 60 days prior written notice to us. All of our other key personnel are employed on an at-will basis with no formal employment agreements. We do not maintain
“Key Man” life insurance on any executives.

We are subject to significant costs and uncertainties related to compliance with the extensive regulations that govern the manufacturing, labeling, distribution, promotion and sale of
pharmaceutical products as well as environmental, safety and health regulations.

The  manufacturing,  distribution,  processing,  formulation,  packaging,  labeling,  promotion  and  sale  of  our  products  are  subject  to  extensive  regulation  by  federal  agencies,
including the FDA, DEA, FTC, Consumer Product Safety Commission and Environmental Protection Agency, among others. We are also subject to state and local laws, regulations and
agencies in California, New Jersey, Pennsylvania and elsewhere, as well as the laws and regulations of Taiwan. Such regulations are also subject to change by the relevant federal, state
and international agencies. For instance, beginning from January 1, 2015, manufacturers, wholesale distributors, and repackagers of certain prescription drugs are required to provide and
capture  certain  product  tracing  information  under  the  Drug  Quality  and  Security  Act  (“DQSA”).  Title  II  of  the  DQSA,  referred  to  as  the  Drug  Supply  Chain  Security  Act,  requires
companies  in  certain  prescription  drugs’  chain  of  distribution  to  build  electronic,  interoperable  systems  to  identify  and  trace  the  products  as  they  are  distributed  in  the  United  States.
Compliance  with  the  DQSA  or  any  future  federal  or  state  electronic  pedigree  requirements  may  increase  the  Company's  operational  expenses  and  impose  significant  administrative
burdens.

Regulatory agencies such as the FDA regularly inspect our manufacturing facilities and the facilities of our third party suppliers. The failure of one of our facilities, or a facility
of one of our third party suppliers, to comply with applicable laws and regulations may lead to breach of representations made to our customers or to regulatory or government action
against  us  related  to  products  made  in  that  facility.  As  discussed  above,  we  have  in  the  past  received  a  warning  letter  and  Form  483  observations  from  the  FDA  regarding  certain
operations within our manufacturing network. During 2015, we successfully resolved the warning letter and we also received the EIRs for each of the FDA inspections resulting in the
Form 483 indicating acceptance of our corrective actions and closure by the FDA of each inspection. Although we remain committed to continuing to improve our quality control and
manufacturing  practices,  we  cannot  be  assured  that  the  FDA  will  continue  to  be  satisfied  with  our  corrective  actions  and  with  our  quality  control  and  manufacturing  systems  and
standards.  If  we  receive  any  future  FDA  observations,  we  may  be  subject  to  regulatory  action  including,  among  others,  monetary  sanctions  or  penalties,  product  recalls  or  seizure,
injunctions, total or partial suspension of production and/or distribution, and suspension or withdrawal of regulatory approvals. Further, other federal agencies, our customers and partners
in our alliance, development, collaboration and other partnership agreements with respect to our products and services may take any such Form 483 observations or warning letters into
account when considering the award of contracts or the continuation or extension of such partnership agreements. If we receive any future Form 483 observations or warning letters from
the FDA, our business, consolidated results of operations and consolidated financial condition could be materially and adversely affected.

With respect to environmental, safety and health laws and regulations, we cannot accurately predict the outcome or timing of future expenditures that we may be required to
make in order to comply with such laws as they apply to our operations and facilities. We are also subject to potential liability for the remediation of contamination associated with both
present and past hazardous waste generation,  handling, and disposal activities.  We are subject  periodically  to environmental  compliance  reviews by environmental,  safety, and health
regulatory agencies. Environmental laws are subject to change and we may become subject to stricter environmental standards in the future and face larger capital expenditures in order to
comply with environmental laws. 

Compliance with federal and state and local law regulations, including compliance with any newly enacted regulations, requires substantial expenditures of time, money and
effort  to  ensure  full  technical  compliance.  Failure  to  comply  with  the  FDA,  EPA  and  other  governmental  regulations  can  result  in  fines,  disgorgement,  unanticipated  compliance
expenditures,  recall  or seizure  of products,  exposure to product  liability  claims,  total  or partial  suspension of production  or distribution,  suspension of the  FDA’s review  of NDAs or
ANDAs, enforcement actions, injunctions and civil or criminal prosecution, any of which could have a material and adverse effect on our business, results of operations and financial
condition.

We  may  experience  reductions  in  the  levels  of  reimbursement  for  pharmaceutical  products  by  governmental  authorities,  HMOs  or  other  third-party  payers.  Any  such  reductions
could have a material adverse effect on our business, results of operations and financial condition.

Various governmental authorities and private health insurers and other organizations, such as HMOs, provide reimbursement to consumers for the cost of certain pharmaceutical
products. Demand for our products depends in part on the extent to which such reimbursement is available. In addition, third-party payers are attempting to control costs by limiting the
level of reimbursement for medical products, including pharmaceuticals, and increasingly challenge the pricing of these products which may adversely affect the pricing of our products.
Moreover, health care reform has been, and is expected to continue to be, an area of national and state focus, which could result in the adoption of measures that could adversely affect the
pricing of pharmaceuticals or the amount of reimbursement available from third-party payers for our products.

Reporting and payment obligations under the Medicaid rebate program and other government programs are complex, and failure to comply could result in sanctions and penalties or
we could be required to reimburse the government for underpayments, which could have a material adverse effect on our business.

Medicaid and other government reporting and payment obligations are highly complex and somewhat ambiguous. State attorneys general and the U.S. Department of Justice
have brought suits or instituted investigations against a number of other pharmaceutical companies for failure to comply with Medicaid and other government reporting obligations. Our
methodologies for making these calculations are complex and the judgments involved require us to make subjective decisions, such that these calculations are subject to the risk of errors.
Government agencies may impose civil or criminal sanctions, including fines, penalties and possible exclusion from federal health care programs, including Medicaid and Medicare. Any
such penalties or sanctions could have a material adverse effect on our business, results of operations and financial condition.

Legislative or regulatory programs that may influence prices of prescription drugs could have a material adverse effect on our business.

Current  or  future  federal  or  state  laws  and  regulations  may  influence  the  prices  of  drugs  and,  therefore,  could  adversely  affect  the  prices  that  we  receive  for  our  products.
Programs in existence in certain states seek to set prices of all drugs sold within those states through the regulation and administration of the sale of prescription drugs. Expansion of these
programs,  in  particular,  state  Medicaid  programs,  or  changes  required  in  the  way  in  which  Medicaid  rebates  are  calculated  under  such  programs,  could  adversely  affect  the  price  we
receive for our products and could have a material adverse effect on our business, results of operations and financial condition. Further, prescription drug prices have been the focus of
increased scrutiny by the government, including certain state attorneys general, members of congress and the U.S. Department of Justice. Decreases in health care reimbursements or
prices of our prescription drugs could limit our ability to sell our products or decrease our revenues, which could have a material adverse effect on our business, results of operations and
financial condition.

Our failure to comply with the legal and regulatory requirements governing sales, marketing and pricing of our products may result in substantial fines, sanctions and restrictions on
our business activities.

Our practices and activities related to the sales and marketing of our products, as well as the pricing of our products, are subject to extensive regulation under U.S. federal and
state healthcare statutes and regulations intended to combat fraud and abuse to federal and state healthcare payment programs, such as Medicare and Medicaid, Tri-Care, CHAMPUS, and
Department of Defense programs. These laws include the federal Anti-Kickback Statute, the federal False Claims Act, and similar state laws and implementing regulations. For example,
the  payment  of  any  incentive  to  a  healthcare  provider  to  induce  the  recommendation  of  our  product  or  the  purchase  of  our  products  reimbursable  under  a  federal  or  state  program  is
prohibited under these laws. Likewise, knowingly presenting or causing to be presented a false claim for payment to a federal or state health care program would expose a company to
sanctions and penalties. Similarly, the inaccurate reporting of prices leading to inflated reimbursement rates would also be considered a violation of these laws. The Physician Payment
Sunshine Act enacted in 2010 imposes reporting and disclosure requirements on drug manufacturers for any “transfer of value” made or distributed to prescribers and other healthcare
providers. Failure to submit this required information may result in significant civil monetary penalties. These laws and regulations are enforced by the U.S. Department of Justice, the
U.S. Department of Health and Human Services, Office of Inspector General, state Medicaid Fraud Units and other state enforcement agencies.

Violations of the laws and regulations described above are punishable by criminal and civil sanctions, including substantial fines and penal sanctions, such as imprisonment. It is
common for enforcement  agencies  to initiate  investigations  into sales and marketing practices,  as well as pricing  practices,  regardless of merit.  These types of investigations and any
related litigation can result in: (i) large expenditures of cash for legal fees, payment for penalties, and compliance activities; (ii) limitations on operations; (iii) diversion of management
resources; (iv) injury to our reputation; and (v) decreased demand for our products.

While we have developed corporate compliance programs based on what we believe to be current best practices, we cannot assure you that we or our employees or agents are or
will be in compliance with all applicable federal or state regulations and laws. Further, the criteria for determining compliance are often complex and subject to change and interpretation.
If we are in violation of any of these requirements or any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions
could include the imposition of significant criminal and civil fines and penalties, exclusion from federal healthcare programs or other sanctions, any which could have a material and
adverse effect on our business, results of operations and financial condition.

We  have  entered  into,  and  anticipate  entering  into,  contracts  with  various  U.S.  government  agencies.  Unfavorable  provisions  in  government  contracts,  some  of  which  may  be
customary, may harm our business, results of operations and financial condition.

Government contracts customarily contain provisions that give the government substantial rights and remedies, many of which are not typically found in commercial contracts,

including provisions that allow the government to:

●
●
●
●
●
●
●
●
●

suspend or debar the contractor from doing business with the government or a specific government agency;
terminate existing contracts, in whole or in part, for any reason or no reason;
reduce the scope and value of contracts;
change certain terms and conditions in contracts;
claim rights to products, including intellectual property, developed under the contract;
take actions that result in a longer development timeline than expected;
direct the course of a development program in a manner not chosen by the government contractor;
audit and object to the contractor’s contract-related costs and fees, including allocated indirect costs; and
control and potentially prohibit the export of the contractor’s products.

Generally,  government  contracts  contain  provisions  permitting  unilateral  termination  or  modification,  in  whole  or  in  part,  at  the  government’s  convenience.  Under  general
principles of government contracting law, if the government terminates a contract for convenience, the terminated company may recover only its incurred or committed costs, settlement
expenses and profit on work completed prior to the termination.

If the government terminates a contract for default, the defaulting company is entitled to recover costs incurred and associated profits on accepted items only and may be liable
for excess costs incurred by the government in procuring undelivered items from another source.  Some government contracts grant the government the right to use, for or on behalf of the
U.S. government, any technologies developed by the contractor under the government contract. If we were to develop technology under a contract with such a provision, we might not be
able to prohibit third parties, including our competitors, from using that technology in providing products and services to the government.

As a government contractor, we may also become subject to periodic audits and reviews. As part of any such audit or review, the government may review the adequacy of, and
our compliance with, our internal control systems and policies, including those relating to our purchasing, property, compensation and/or management information systems. In addition, if
an  audit  or  review  uncovers  any  improper  or  illegal  activity,  we  may  be  subject  to  civil  and  criminal  penalties  and  administrative  sanctions,  including  termination  of  our  contracts,
forfeiture  of  profits,  suspension  of  payments,  fines  and  suspension  or  prohibition  from  doing  business  with  the  government.  We  could  also  suffer  serious  harm  to  our  reputation  if
allegations of impropriety were made against us.

Legislative or regulatory reform of the healthcare system in the United States may harm our future business.

The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, collectively commonly referred to as the “Healthcare Reform
Act” may affect the operational results of companies in the pharmaceutical industry such as ours by imposing additional costs. Effective January 1, 2010, the Health Care Reform Act,
amongst other changes, increased the minimum Medicaid drug rebates for pharmaceutical companies and revised the definition of “average manufacturer price” for reporting purposes,
which may affect the amount of our Medicaid drug rebates to states. Beginning in 2011, the law also imposed a significant annual fee on companies that manufacture or import branded
prescription drug products.

The Healthcare Reform Act contemplates the promulgation of significant future regulatory action which may also further affect our business. The Healthcare Reform Act and
any  further  changes  to  health  care  laws  or  regulatory  framework  that  reduce  our  revenues  or  increase  our  costs  could  also  have  a  material  adverse  effect  on  our  business,  results  of
operations and financial condition.

32

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
   
 
 
 
 
We depend on our intellectual property, and our future success is dependent on our ability to protect our intellectual property and not infringe on the rights of others.

We believe intellectual property protection is important to our business and that our future success will depend, in part, on our ability to obtain patent protection, maintain trade

secret protection and operate without infringing on the rights of others. We cannot assure you that:

any of our future processes or products will be patentable;
our processes or products will not infringe upon the patents of third parties; or

●
●
● we will have the resources to defend against charges of patent infringement by third parties or to protect our own rights against infringement by third parties.

We rely on trade secrets and proprietary knowledge related to our products and technology which we generally seek to protect by confidentiality and non-disclosure agreements
with employees, consultants, licensees and pharmaceutical companies. If these agreements are breached, we may not have adequate remedies for any breach, and our trade secrets may
otherwise become known by our competitors.

We are subject to potential product liability claims that can result in substantial litigation costs and liability.

The  design,  development  and  manufacture  of  pharmaceutical  products  involve  an  inherent  risk  of  product  liability  claims  and  associated  adverse  publicity.  Product  liability
insurance coverage is expensive, difficult to obtain, and may not be available in the future on acceptable terms, or at all. Although we currently carry $50.0 million of such insurance, we
believe that no reasonable amount of insurance can fully protect against all such risks because of the potential liability inherent in the business of producing pharmaceutical products for
human consumption.

We face risks relating to our goodwill and intangibles.

At December 31, 2015, our goodwill, which includes goodwill generated as a result of the Tower acquisition, in addition to goodwill generated as a result of the December 1999
merger of Global Pharmaceuticals Corporation and Impax Pharmaceuticals, Inc., was approximately $210.2 million, or approximately 11% of our total assets. The carrying value of our
intangible  assets,  composed  of  product  rights,  in-process  research  and  development,  and  royalties  was  approximately  $602.0  million,  or  approximately  31%  of  our  total  assets.  The
increase in carrying value of $576.9 million from the December 31, 2014 carrying value of $26.7 million was attributable to the Tower acquisition. We may never realize the value of our
goodwill and intangibles. We regularly evaluate and will continue to regularly evaluate whether events or circumstances have occurred to indicate all, or a portion, of the carrying amount
of goodwill or intangible assets may no longer be recoverable, in which case an impairment charge to earnings would become necessary. Goodwill and intangible assets are tested at least
annually for impairment in accordance with Accounting Standards Codification (“ASC”) 350, Intangibles – Goodwill and Other. We perform this impairment testing during the fourth
quarter of our fiscal year. During the three month period ended September 30, 2013, we recorded a $13.2 million impairment charge to cost of revenues for our Impax Generics division
as  a  result  of  deteriorating  market  conditions.  During  the  same  period  in  2013,  we  also  recorded  an  intangible  asset  impairment  charge  of  $0.8  million  in  research  and  development
expenses as a result of a decision by management to withdraw one of our ANDAs and no longer seek FDA approval. The impairment charge represented the full carrying value of the
ANDA. During the three month period ended March 31, 2014, as a result of a further decline in pricing, we revised our projections and performed an intangible asset impairment analysis.
Based on the results of this analysis, we recorded a $2.9 million charge to cost of revenues for the Impax Generics division during 2014. As a result of our annual impairment testing
performed during the fourth quarter of 2015, we recorded a total impairment charge related to our intangible assets of approximately $13.7 million, of which $7.3 million was recorded to
cost of revenues and $6.4 million was recorded to research and development expenses on our Consolidated Statements of Income. The impairment charge was primarily attributable to
deteriorating market conditions for two of the intangible assets acquired in the Tower acquisition. There was no impairment charge related to goodwill as a result of our annual testing in
2015. Any future acquisitions or investments in businesses could also result in an increase in goodwill, intangible assets and amortization expenses that could have a negative impact on
our profitability. If the fair value of our goodwill or intangible assets is determined at some future date to be less than its recorded value, a change to earnings may be required. Any such
charge  or  future  determination  requiring  the  write-off  of  a  significant  portion  of  the  carrying  value  of  our  goodwill  or  intangible  assets  could  have  a  material  adverse  effect  on  our
business, results of operations and financial condition.

33

 
 
 
 
 
 
 
 
 
 
 
 
 
Changes in tax regulations and varying application and interpretations of these regulations could result in an increase in our existing and future tax liabilities.   

We have potential tax exposures resulting from the varying application of statutes, regulations and interpretations, including exposures with respect to manufacturing, research
and development, marketing, sales and distribution functions. Although our arrangements are based on accepted tax standards, tax authorities in various jurisdictions including the United
States may disagree with and subsequently challenge the amount of profits taxed, which may increase our tax liabilities and could have a material adverse effect on our business, results
of our operations and financial condition.

If we are unable to manage our growth, our business will suffer.

We have experienced rapid growth in the past several years and anticipate continued rapid expansion in the future. This growth has required us to expand, upgrade, and improve
our  administrative,  operational,  and  management  systems,  internal  controls  and  resources.  We  anticipate  additional  growth  in  connection  with  the  expansion  of  our  manufacturing
operations, development of our brand-name products, and our marketing and sales efforts for the products we develop. Although we cannot assure you that we will, in fact, grow as we
expect, if we fail to manage growth effectively or to develop a successful marketing approach, our business and financial results will be materially harmed. We may also seek to expand
our  business  through  complementary  or  strategic  acquisitions  of  other  businesses,  products  or  assets,  or through  joint  ventures,  strategic  agreements  or  other  arrangements.  Any such
acquisitions,  joint  ventures  or  other  business  combinations  may  involve  significant  integration  challenges,  operational  complexities  and  time  consumption  and  require  substantial
resources  and effort.  It may also disrupt  our ongoing businesses,  which may adversely  affect  our relationships  with customers,  employees,  regulators  and others  with whom we have
business or other dealings. Further, if we are unable to realize synergies or other benefits expected to result from any acquisitions, joint ventures or other business combinations, or to
generate additional revenue to offset any unanticipated inability to realize these expected synergies or benefits, our growth and ability to compete may be impaired, which would require
us to focus additional resources on the integration of operations rather than other profitable areas of our business, and may otherwise cause a material adverse effect on our business,
results of operations and financial condition.

We may make acquisitions of, or investments in, complementary technologies, businesses or products, which may be on terms that are not commercially advantageous, may require
additional  debt  or  equity  financing,  and  may  involve  numerous  risks,  including  the  risks  that  we  may  be  unable  to  integrate  the  acquired  business  successfully  and  that  we  may
assume liabilities that adversely affect us.

We regularly review the potential acquisition of technologies, products, product rights and complementary  businesses. We may choose to enter into such transactions at any
time. Nonetheless, we cannot provide assurance that we will be able to identify suitable acquisition or investment candidates. To the extent that we do identify candidates that we believe
to be suitable, we cannot provide assurance that we will be able to make such acquisitions or investments on commercially advantageous terms or at all. Further, there are a number of
risks and uncertainties  relating  to closing such transactions.  If such transactions  are not completed  for any reason, we will be subject to several  risks, including  the following: (i) the
market  price of shares of our common stock may reflect  a market  assumption that such transactions  will occur, and a failure  to complete  such transactions  could result in a negative
perception by the market of us generally and a decline in the market price of our common stock; and (ii) many costs relating to the such transactions may be payable by us whether or not
such transactions are completed.

If we make any acquisitions or investments, we may finance such acquisitions or investments through our cash reserves, debt financing, or by issuing additional equity securities,
which could dilute the holdings of our then-existing stockholders. If we require financing, we cannot provide assurance that we will be able to obtain required financing when needed on
acceptable terms or at all. Any such acquisitions or investments could also result in an increase in goodwill, intangible assets and amortization expenses that could ultimately negatively
impact our profitability. If the fair value of our goodwill or intangible assets is determined at some future date to be less than its recorded value, a charge to earnings may be required.
Further, our consolidated financial statements may also be impacted in future periods based on the accuracy of our valuations of any businesses we acquire. Such a charge to earnings or
impact on our consolidated financial statements could be in amounts that are material to our business, results of operations and financial condition.

34

 
 
 
 
 
 
 
 
 
 
Additionally,  acquisitions  involve  numerous  risks,  including  difficulties  in  assimilating  the  personnel,  operations  and  products  of  the  acquired  companies,  the  diversion  of
management’s attention from other business concerns, risks of entering markets in which we have limited or no prior experience, and the potential loss of key employees of the acquired
company. There may be overlap between our products or customers and those of an acquired entity that may create conflicts in relationships or other commitments detrimental to the
integrated businesses. If we are unable to successfully or timely integrate the operations of acquired companies with our business, we may incur unanticipated liabilities and be unable to
realize the revenue growth, synergies and other anticipated benefits resulting from the acquisition, and our business, results of operations and financial condition could be materially and
adversely affected.

As a result of acquiring businesses, we may incur significant transaction costs, including substantial fees for investment bankers, attorneys, accountants and financial printing.
Any acquisition could result in our assumption of unknown and/or unexpected,  perhaps material  liabilities.  Additionally, in any acquisition agreement,  the negotiated  representations,
warranties and agreements of the selling parties may not entirely protect us, and liabilities resulting from any breaches could exceed negotiated indemnity limitations.

There are inherent uncertainties involved in estimates, judgments and assumptions used in the preparation of financial statements in accordance with GAAP. Any future changes in
estimates, judgments and assumptions used or necessary revisions to prior estimates, judgments or assumptions could lead to a restatement of our results. 

The consolidated financial statements included in this Annual Report on Form 10-K are prepared in accordance with GAAP. This involves making estimates, judgments and
assumptions that affect reported amounts of assets (including intangible assets), liabilities, revenues, expenses and income. Estimates, judgments and assumptions are inherently subject to
change in the future and any necessary revisions to prior estimates, judgments or assumptions could lead to a restatement. Any such changes could result in corresponding changes to the
amounts of assets (including goodwill and other intangible assets), liabilities, revenues, expenses and income.

The terms of our senior secured credit facility and the indenture governing our 2.00% Convertible Senior Notes Due June 2022 impose financial and operating restrictions on us.

We have a $100.0 million senior secured revolving credit facility (the “Senior Secured Credit Facility”) pursuant to a credit agreement, dated as of August 4, 2015, by and among
us, the lenders party thereto from time to time and Royal Bank of Canada, as administrative agent and collateral agent. We are also party to an indenture dated June 30, 2015 between us
and Wilmington Trust, National Association (the “Indenture”) governing our 2.00% Convertible Senior Notes Due 2022 (the “Notes”). Our Senior Secured Credit Facility and Indenture
contain a number of negative covenants that limit our ability to engage in activities. These covenants limit or restrict, among other things, our ability to:

undertake certain acquisitions, mergers or consolidations, or dispose of assets;

incur additional debt, guarantee other obligations or grant liens on our assets;

●
● make certain loans or investments;
●
● make optional payments or modify certain debt instruments;
●
●

pay dividends or other payments on our capital stock, enter into arrangements that restrict our and our restricted subsidiaries’ ability to pay dividends or grant liens; or
engage in certain transactions with our affiliates.

The terms of our Senior Secured Credit Facility also include a financial covenant which requires us to maintain a certain total net leverage ratio. These limitations and restrictions
may adversely affect our ability to finance our future operations or capital needs or engage in other business activities that may be in our best interests.  If we breach any of the covenants
in our Senior Secured Credit Facility or Indenture, we may be in default and our borrowings under the facility and the Notes could be declared due and payable, including accrued interest
and other fees, which could have a material adverse effect on our business, results of operations and financial condition.

Our  level  of  indebtedness  and  liabilities  could  limit  cash  flow  available  for  our  operations,  expose  us  to  risks  that  could  adversely  affect  our  business,  results  of  operations  and
financial condition and impair our ability to satisfy our obligations under our convertible notes and other debt instruments.

At December 31, 2015, our total consolidated liabilities were $860.1 million, including $600 million of outstanding convertible notes. We may also incur additional indebtedness to

meet future financing needs. Our indebtedness could have significant negative consequences for our business, results of operations and financial condition, including:

●
●
●

●
●
●

increasing our vulnerability to adverse economic and industry conditions;
limiting our ability to obtain additional financing;
requiring the dedication of a substantial portion of our cash flow from operations to service our indebtedness, thereby reducing the amount of our cash flow available for
other purposes;
limiting our flexibility in planning for, or reacting to, changes in our business;
dilution experienced by our existing stockholders as a result of the conversion of the convertible notes into shares of common stock; and
placing us at a possible competitive disadvantage with less leveraged competitors and competitors that may have better access to capital resources.

35

 
 
 
   
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We cannot assure you that we will be able to continue to maintain sufficient cash reserves or continue to generate cash flow from operations at levels sufficient to permit us to
pay principal,  premium,  if any, and interest  on our indebtedness,  or that our cash needs  will not increase.  If we are unable  to generate  sufficient  cash  flow or otherwise obtain  funds
necessary to make required payments, or if we fail to comply with the various requirements of our indebtedness then outstanding, we would be in default, which would permit the holders
of the affected  indebtedness  to accelerate  the maturity  of such indebtedness  and could  cause  defaults  under our other  indebtedness.  Any default  under any indebtedness  could have a
material adverse effect on our business, results of operations and financial condition.

If we fail to maintain an effective system of internal control over financial reporting, we may not be able to accurately report our financial results, timely file our periodic reports,
maintain our reporting status or prevent fraud.    

Our  management  or  our  independent  registered  public  accounting  firm  may  identify  material  weaknesses  in  our  internal  control  over  financial  reporting  in  the  future.  The
existence of internal control material weaknesses may result in current and potential stockholders and alliance and collaboration agreements’ partners losing confidence in our financial
reporting, which could harm our business, the market price of our common stock, and our ability to retain our current, or obtain new, alliance and collaboration agreements’ partners.

In addition, the existence of material weaknesses in our internal control over financial reporting may affect our ability to timely file periodic reports under the Exchange Act.
Although we remedied any past accounting issues and do not believe similar accounting problems are likely to recur, an internal control material weakness may develop in the future and
affect our ability to timely file our periodic reports. The inability to timely file periodic reports under the Exchange Act could result in the SEC revoking the registration of our common
stock, which would prohibit us from listing or having our stock quoted on any public market. This would have an adverse effect on our business and stock price by limiting the publicly
available information regarding us and greatly reducing the ability of our stockholders to sell or trade our common stock.

Terrorist attacks and other acts of violence or war may adversely affect our business.

Terrorist attacks at or nearby our facilities in Hayward, California, Middlesex, New Jersey, or our manufacturing facility in Taiwan may negatively affect our operations. While
we do not believe that we are more susceptible to such attacks than other companies, such attacks could directly affect our physical facilities or those of our suppliers or customers and
could make the transportation of our products more difficult and more expensive and ultimately affect our sales.

We  carry  insurance  coverage  on  our  facilities  of  types  and  in  amounts  that  we  believe  are  in  line  with  coverage  customarily  obtained  by  owners  of  similar  properties.  We
continue to monitor the state of the insurance market in general and the scope and cost of coverage for acts of terrorism in particular, but we cannot anticipate what coverage will be
available on commercially reasonable terms in future policy years. Currently, we carry terrorism insurance as part of our property and casualty and business interruption coverage. If we
experience a loss that is uninsured or that exceeds policy limits, we could lose the capital invested in the damaged facilities, as well as the anticipated future net sales from those facilities.

Because of the location of our manufacturing and research and development facilities, our operations could be interrupted by an earthquake or be susceptible to climate changes. 

Our corporate headquarters in California, manufacturing operations in California and Taiwan, and research and development activities related to process technologies are located
near major earthquake fault lines. Although we have other facilities, we produce a substantial portion of our products at our California facility. A disruption at these California facilities
due to an earthquake, other natural disaster, or due to climate changes, even on a short-term basis, could impair our ability to produce and ship products to the market on a timely basis. In
addition,  we  could  experience  a  destruction  of  facilities  which  would  be  costly  to  rebuild,  or  loss  of  life,  all  of  which  could  materially  adversely  affect  our  business  and  results  of
operations.

36

 
 
 
 
 
 
 
 
   
 
 
 
We presently carry $10.0 million of earthquake coverage which covers all of our facilities on a worldwide basis. We carry an additional $40.0 million of earthquake coverage
specifically  for  our  California  facilities.  We  believe  the  aggregate  amount  of  earthquake  coverage  we  currently  carry  is  appropriate  in  light  of  the  risks;  however,  the  amount  of  our
earthquake insurance coverage may not be sufficient to cover losses from earthquakes. We may discontinue some or all of this insurance coverage in the future if the cost of premiums
exceeds the value of the coverage discounted for the risk of loss. If we experience a loss that is uninsured or that exceeds policy limits, we could lose the capital invested in the damaged
facilities, as well as the anticipated future net sales from those facilities.

The  expansion  of  social  media  platforms  present  new  risks  and  challenges,  which  could  cause  a  material  adverse  effect  on  our  business,  results  of  operations  and  financial
condition.

The  inappropriate  use  of  certain  media  vehicles  could  cause  brand  damage  or  information  leakage  or  could  lead  to  legal  implications  from  the  improper  collection  and/or
dissemination of personally identifiable information. In addition, negative posts or comments about us on any social networking website could seriously damage our reputation. Further,
the disclosure of non-public company sensitive information through external media channels could lead to information loss as there might not be structured processes in place to secure
and protect information. If our non-public sensitive information is disclosed or if our reputation is seriously damaged through social media, it could have a material adverse effect on our
business, results of operations and financial condition.

* This facility is on land that is leased from the state.

In our various facilities we maintain an extensive equipment base that includes new or recently reconditioned equipment for the manufacturing and packaging of compressed
tablets, coated tablets and capsules. The manufacturing and research and development equipment includes mixers and blenders for capsules and tablets, automated capsule fillers, tablet
presses, particle reduction, sifting equipment, and tablet coaters. The packaging equipment includes fillers, cottoners, cappers, and labelers. We also maintain two well equipped, modern
laboratories used to perform all the required physical and chemical testing of our products. We also maintain a broad variety of material handling and cleaning, maintenance, and support
equipment. We own substantially all of our manufacturing equipment and believe it is well maintained and suitable for its requirements.

We maintain property and casualty and business interruption insurance in amounts we believe are sufficient and consistent with practices for companies of comparable size and

business.

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

The  following  discussion  and analysis,  as  well  as  other  sections  in  this  report,  should  be  read  in conjunction  with  the  consolidated  financial  statements  and  related  Notes  to

Consolidated Financial Statements included elsewhere herein. All references to years mean the relevant 12-month period ended December 31.

Overview

We are a specialty pharmaceutical  company applying formulation and development  expertise, as well as our drug delivery  technology, to the development,  manufacture  and
marketing of bioequivalent pharmaceutical products, commonly referred to as “generics,” in addition to the development and marketing of branded products. We operate in two segments,
referred to as “Impax Generics” and “Impax Specialty Pharma”. Impax Generics concentrates its efforts on generic products, which are the pharmaceutical and therapeutic equivalents of
brand-name drug products and are usually marketed under their established nonproprietary drug names rather than by a brand name. Impax Specialty Pharma utilizes its specialty sales
force to market proprietary branded pharmaceutical products for the treatment of CNS disorders and other select specialty segments. Both Impax Generics and Impax Specialty Pharma
generate revenue from research and development services provided to unrelated third-party pharmaceutical entities.

We plan to continue to expand Impax Generics through targeted ANDAs and a first-to-file and first-to-market strategy and to continue to evaluate and pursue external growth
initiatives,  including  acquisitions  and  partnerships.  We  focus  our  efforts  on  a  broad  range  of  therapeutic  areas  including  products  that  have  technically  challenging  drug-delivery
mechanisms  or  unique  product  formulations.  We  employ  our  technologies  and  formulation  expertise  to  develop  generic  products  that  reproduce  brand-name  products’  physiological
characteristics but do not infringe any valid patents relating to such brand-name products. We generally focus our generic product development on brand-name products as to which the
patents covering the active pharmaceutical ingredient have expired or are near expiration, and we employ our proprietary formulation expertise to develop controlled-release technologies
that do not infringe patents covering the brand-name products’ controlled-release technologies. We also develop, manufacture, sell and distribute specialty generic pharmaceuticals that
we  believe  present  one  or  more  competitive  advantages,  such  as  difficulty  in  raw  materials  sourcing,  complex  formulation  or  development  characteristics  or  special  handling
requirements.  In  addition  to  our  focus  on  solid  oral  dosage  products,  we  have  expanded  our  generic  pharmaceutical  products  portfolio  to  include  alternative  dosage  form  products,
primarily through alliance and collaboration agreements with third parties. As of February 16, 2016, we marketed 139 generic pharmaceuticals, which represent dosage variations of 55
different pharmaceutical compounds through our Impax Generics division; another five of our generic pharmaceuticals representing dosage variations of two different pharmaceutical
compounds are marketed by our alliance and collaboration agreement partners. As of February 16, 2016, we had 25 applications pending at the FDA and 18 other products in various
stages of development for which applications have not yet been filed.

The Impax Generics division develops, manufactures, sells, and distributes generic pharmaceutical products primarily through the following sales channels:

●
●

●

●

the “Impax Generics sales channel” for sales of generic prescription products we sell directly to wholesalers, large retail drug chains, and others;
the “Private Label Product sales channel” for generic pharmaceutical over-the-counter and prescription products we sell to unrelated third-party customers who in-turn
sell the product to third parties under their own label;
the “Rx Partner sales channel” for generic prescription products sold through unrelated third-party pharmaceutical entities under their own label pursuant to alliance
agreements; and
the “OTC Partner sales channel” for sales of generic pharmaceutical over-the-counter products sold through unrelated third-party pharmaceutical entities under their
own label pursuant to alliance agreements.

We sell our Impax Generics division products within the continental United States and the Commonwealth of Puerto Rico. We have no sales in foreign countries. Revenues from
the Impax Generics sales channel and the Private Label Product sales channel are reported under the caption “Impax Generics sales, net” in our consolidated statements of income. We
also generate revenue in our Impax Generics division from research and development services provided under a joint development agreement with another pharmaceutical company, and
we report such revenue under the caption “Other Revenues” in “Item 15. Exhibits and Financial Statement Schedules – Note 24. Supplementary Financial Information.”

Impax Specialty Pharma is focused on developing proprietary branded pharmaceuticals products for the treatment of CNS disorders, which include migraine, multiple sclerosis,
Parkinson’s  disease  and  post  herpetic  neuralgia,  as  well  as  developing  other  select  specialty  products.  Impax  Specialty  Pharma  in  involved  in  the  promotion  and  sale  of  branded
pharmaceutical products through our specialty sales force. We believe that we have the research, development and formulation expertise to develop branded products that will deliver
significant improvements over existing therapies.

Our  branded  pharmaceutical  product  portfolio  consists  of  commercial  CNS  and  other  select  specialty  products,  as  well  as  development  stage  projects.  In  February  2012,  we
licensed  from  AZ  the  exclusive  U.S.  commercial  rights  to  Zomig®  (zolmitriptan)  tablet,  orally  disintegrating  tablet  and  nasal  spray  formulations  pursuant  to  the  terms  of  the  AZ
Agreement and began sales of the Zomig® products under our label during the year ended December 31, 2012 through our specialty sales force. In May 2013, our exclusivity period for
branded Zomig® tablets and orally disintegrating tablets expired and we launched authorized generic versions of those products in the United States. In June 2015, the FDA approved the
Zomig® nasal spray for use in pediatric patients 12 years of age or older for the acute treatment of migraine with or without aura. Our branded products portfolio also includes Albenza®
for invasive tapeworm infections, and two additional marketed products, all acquired in our acquisition of Tower and Lineage.

We currently market one internally developed branded pharmaceutical product, Rytary® (IPX066), for the treatment of Parkinson’s disease, post-encephalitic parkinsonism, and
parkinsonism that may follow carbon monoxide intoxication and/or manganese intoxication, which was approved by the FDA on January 7, 2015 and which we launched in the United
States in April 2015. In November 2015, the European Commission granted marketing authorization for NUMIENT™ (IPX066) (referred to as Rytary® in the United States). The review
of the NUMIENT™ application was conducted under the centralized licensing procedure as a therapeutic innovation, and the authorization is applicable in all 28 member states of the
European Union, as well as Iceland, Liechtenstein and Norway.

We  have  entered  into  several  alliance,  collaboration  or  license  and  distribution  agreements  with  respect  to  certain  of  our  products  and  services  and  may  enter  into  similar
agreements in the future. These agreements may require us to relinquish rights to certain of our technologies or product candidates, or to grant licenses on terms which ultimately may
prove to be unfavorable to us. Relationships with alliance and collaboration partners may also include risks due to the failure of a partner to perform under the agreement, incomplete
marketplace information, inventories, development capabilities, regulatory compliance and commercial strategies of our partners and our agreements may be the subject of contractual
disputes. For instance, we have historically experienced some disruptions in supply of certain products. If we suffer similar supply failures on our significant products in the future, or if
we or our partners are not successful in commercializing the products covered by such alliance, collaboration or license and distribution agreements, our revenues and relationships with
our customers may be materially adversely affected.

Critical Accounting Policies and Use of Estimates

The  preparation  of  our  consolidated  financial  statements  in  accordance  with  accounting  principles  generally  accepted  in  the  United  States  (“GAAP”)  and  the  rules  and
regulations of the U.S. Securities & Exchange Commission (“SEC”) require the use of estimates and assumptions, based on complex judgments considered reasonable, and affect the
reported amounts of assets and liabilities and disclosure of contingent assets and contingent liabilities at the date of the consolidated financial statements and the reported amounts of
revenues  and  expenses  during  the  reporting  period.  The  most  significant  judgments  are  employed  in  estimates  used  in  determining  values  of  tangible  and  intangible  assets,  legal
contingencies, tax assets and tax liabilities, fair value of share-based compensation related to equity incentive awards issued to employees and directors, and estimates used in applying
the our revenue recognition policy including those related to accrued chargebacks, rebates, distribution service fees, product returns, Medicare, Medicaid, and other government rebate
programs, shelf-stock adjustments, and the timing and amount of deferred and recognized revenue under the our several alliance and collaboration agreements. Actual results may differ
from estimated results. Certain prior year amounts have been reclassified to conform to the presentation for the year ended December 31, 2015.

Although  we  believe  our  estimates  and  assumptions  are  reasonable  when  made,  they  are  based  upon  information  available  to  us  at  the  time  they  are  made.  We  periodically
review the factors having an influence on our estimates and, if necessary, adjust such estimates. Although historically our estimates have generally been reasonably accurate, due to the
risks and uncertainties involved in our business and evolving market conditions, and given the subjective element of the estimates made, actual results may differ from estimated results.
This possibility may be greater than normal during times of pronounced economic volatility.

Impax Generics sales, net, and Impax Specialty Pharma sales, net. Revenue from the sale of products is recognized when title and risk of loss of the product is transferred to the
customer and the sales price is fixed and determinable. Provisions for discounts, early payments, rebates, sales returns and distributor chargebacks under terms customary in the industry
are provided for in the same period the related sales are recorded. We record estimated reductions to revenue at the time of the initial sale and these estimates are based on the sales terms,
historical experience and trend analysis.

Gross to Net Sales Accruals. We base our sales returns allowance on estimated on-hand inventories at our customers, measured end-customer demand as reported by third-party
sources,  actual  returns  history  and  other  factors,  such  as  the  trend  experience  for  lots  where  product  is  still  being  returned  or  inventory  centralization  and  rationalization  initiatives
conducted by major pharmacy chains, as applicable. If the historical data we use to calculate these estimates do not properly reflect future returns, then a change in the allowance would
be made in the period in which such a determination is made and revenues in that period could be materially affected. Under this methodology, we track actual returns by individual
production lots. Returns on closed lots, that is, lots no longer eligible for return credits, are analyzed to determine historical returns experience. Returns on open lots, that is, lots still
eligible for return credits, are monitored and compared with historical return trend rates. Any changes from the historical trend rates are considered in determining the current sales return
allowance.

Sales discount accruals are based on payment terms extended to customers.

Government  rebate  accruals  are  based on estimated  payments  due to governmental  agencies  for purchases  made  by third parties  under various  governmental  programs.  U.S.
Medicaid rebate accruals are generally based on historical payment data and estimates of future Medicaid beneficiary utilization applied to the Medicaid unit rebate formula established
by the Center for Medicaid and Medicare Services. The Medicaid rebate percentage was increased and extended to Medicaid Managed Care Organizations in March 2010. The accrual of
the  rebates  associated  with  Medicaid  Managed  Care  Organizations  is  calculated  based  on  actual  billings  received  from  the  states.  We  adjust  the  rebate  accruals  as  more  information
becomes available and to reflect actual claims experience. Effective January 1, 2011, manufacturers of pharmaceutical products are responsible for 50% of the patient’s cost of branded
prescription drugs related to the Medicare Part D Coverage Gap. In order to estimate the cost to us of this coverage gap responsibility, we analyze the historical invoices. This expense is
recognized throughout the year as costs are incurred.

Rebates  or  administrative  fees  are  offered  to  certain  customers,  group  purchasing  organizations  and  pharmacy  benefit  managers,  consistent  with  pharmaceutical  industry
practices. Settlement of rebates and fees may generally occur from one to 15 months from the date of sale. We provide a provision for rebates at the time of sale based on contracted rates
and historical redemption rates. Assumptions used to establish the provision include level of customer inventories, contract sales mix and average contract pricing. We regularly review
the information related to these estimates and adjust the provision accordingly.

Chargeback accruals are based on the differentials between product acquisition prices paid by wholesalers and lower contract pricing paid by eligible customers.

Distributor  service  fee  accruals  are  based  on  contractual  fees  to  be  paid  to  the  wholesale  distributor  for  services  provided.  TRICARE  is  a  health  care  program  of  the  U.S.
Department of Defense Military Health System that provides civilian health benefits for military personnel, military retirees and their dependents. TRICARE rebate accruals are included
in chargeback accruals and are based on estimated Department of Defense eligible sales multiplied by the TRICARE rebate formula.

A  significant  majority  of  our  gross  to  net  accruals  are  the  result  of  chargebacks  and  rebates,  with  the  majority  of  those  programs  having  an  accrual  to  payment  cycle  of
approximately three months. In addition to this relatively short accrual to payment cycle, we receive monthly information from the wholesalers regarding their sales of our products and
actual  on  hand  inventory  levels  of  our  products.  During  the  year  ended  December  31,  2015,  the  three  large  wholesalers  account  for  approximately  98%  of  our  chargebacks  and
approximately 77% of our indirect sales rebates. This enables us to execute accurate provisioning procedures. Consistent with the pharmaceutical industry, the accrual to payment cycle
for  returns  is  longer  and  can  take  several  years  depending  on  the  expiration  of  the  related  products.  However,  returns  represent  the  smallest  gross  to  net  adjustment.  We  have  not
experienced any significant changes in our estimates as it relates to our chargebacks, rebates or returns in each of the years in the three-year period ended December 31, 2015.

The  aggregate  provision  for  chargebacks,  as  a  percent  of  gross  product  sales,  decreased  to  34%  in  2015  from  35%  in  2014  primarily  as  a  result  of  product  sales  mix  and

inclusion of product sales from the Tower acquisition.

The aggregate provision for chargebacks, as a percent of gross product sales, increased to 35% in 2014 from 34% in 2013 primarily as a result of an increase in the estimated
provision  for  chargebacks  related  to  our  authorized  generic  Trilipix®  and  branded  Zomig®  products  during  the  year  ended  December  31,  2014  due  to  price  erosion  resulting  from
increased competition, partially offset by lower chargeback rates on our authorized generic Renvela® tablets and generic Solaraze®, both launched during 2014.

As noted in the table above, the provision for rebates, as a percent of gross product sales, increased from 19% during the year ended December 31, 2014 to 23% during the year
ended December 31, 2015 as a result of product sales mix, the formation of alliances between major wholesalers and major retailers and the inclusion of product sales from the Tower
acquisition which carry a higher rebate rate.

The provision for rebates, as a percent of gross product sales, increased from 17% during the year ended December 31, 2013 to 19% during the year ended December 31, 2014 as

a result of product sales mix, as well as the impact of additional rebates resulting from the recent formation of new alliances between major wholesalers and major retailers.

The provision for returns as a percent of gross product sales increased to 2% in 2015 compared to1% in 2014 as a result of the Tower acquisition whose products carry a higher
historical returns experience, higher than anticipated returns volume resulting from the loss of exclusivity on certain Zomig® products and higher returns accruals due to price increases
on certain generic products.

The provision for returns as a percent of gross product sales remained at 1% in 2014 compared to 2013.

Rx Partner and OTC Partner. Each of our Rx Partner and OTC Partner agreements contain multiple deliverables in the form of products, services and/or licenses over extended
TM 
periods. Financial Accounting Standards Board (“FASB”) Accounting Standards Codification 
(“ASC”) Topic 605-25 supplemented SAB 104 and provides guidance for accounting
for such multiple-element revenue arrangements. With respect to our multiple-element revenue arrangements that are material to our financial results, we determine whether any or all of
the elements of the arrangement should be separated into individual units of accounting under FASB ASC Topic 605-25. If separation into individual units of accounting is appropriate,
we recognize revenue for each deliverable when the revenue recognition criteria specified by SAB 104 are achieved for the deliverable. If separation is not appropriate, we recognize
revenue  and  related  direct  manufacturing  costs  over  the  estimated  life  of  the  agreement  or  our  estimated  expected  period  of  performance  using  either  the  straight-line  method  or  a
modified proportional performance method.

The  Rx  Partners  and  OTC  Partners  agreements  obligate  us  to  deliver  multiple  goods  and/or  services  over  extended  periods.  Such  deliverables  include  manufactured
pharmaceutical  products,  exclusive  and  semi-exclusive  marketing  rights,  distribution  licenses,  and  research  and  development  services.  In  exchange  for  these  deliverables,  we  receive
payments  from  our  agreement  partners  for  product  shipments  and  research  and  development  services,  and  may  also  receive  other  payments  including  royalty,  profit  sharing,  upfront
payments, and periodic milestone payments. Revenue received from our partners for product shipments under these agreements is generally not subject to deductions for chargebacks,
rebates, product returns, and other pricing adjustments. Royalty and profit sharing amounts we receive under these agreements are calculated by the respective agreement partner, with
such royalty and profit share amounts generally based upon estimates of net product sales or gross profit which include estimates of deductions for chargebacks, rebates, product returns,
and other adjustments the alliance agreement partners may negotiate with their customers. We record the agreement partner's adjustments to such estimated amounts in the period the
agreement partner reports the amounts to us.

OTC Partner revenue is related to our alliance and collaboration agreement with Pfizer, Inc., formerly Wyeth LLC (“Pfizer”) and our supply agreement with L. Perrigo Company
(“Perrigo”) with respect to the supply of over-the-counter  pharmaceutical  products. The OTC Partner sales channel is no longer a core area of our business, and the over-the-counter
pharmaceutical  products  we sell through this sales channel are  older products which are only sold to Pfizer  and Perrigo.  We are currently  only required  to manufacture  the over-the-
counter pharmaceutical products under our agreements with Pfizer and Perrigo. We recognize profit share revenue in the period earned.

Research Partner . We have entered into development agreements with unrelated third-party pharmaceutical companies under which we are collaborating in the development of
five dermatological products, including four generic products and one branded dermatological product, and one branded CNS product. Under each of the development agreements, we
received an upfront fee with the potential to receive additional milestone payments upon completion of contractually specified clinical and regulatory milestones. Additionally, we may
also receive royalty payments from the sale, if any, of a successfully developed and commercialized branded product under one of the development agreements. We defer and recognize
revenue received from the achievement of contingent research and development milestones in the period such payment is earned. We will recognize royalty fee income, if any, as current
period revenue when earned.

Estimated Lives of Alliance and Collaboration Agreements. Because we may defer revenue we receive under our alliance agreements, and recognize it over the estimated life of
the related agreement, or our expected period of performance, we are required to estimate the recognition period under each such agreement in order to determine the amount of revenue
to be recognized in each period. Sometimes this estimate is based on the fixed term of the particular alliance agreement. In other cases the estimate may be based on more subjective
factors as noted in the following paragraphs. While changes to the estimated recognition periods have been infrequent, such changes, should they occur, may have a significant impact on
our consolidated financial statements.

As an illustration, the consideration received from the provision of research and development services under the Joint Development Agreement with Valeant Pharmaceuticals
International, Inc. (“Valeant Agreement”), including the upfront fee and milestone payments received before January 1, 2011, have been initially deferred and are being recognized as
revenue  on  a  straight-line  basis  over  our  expected  period  of  performance  to  provide  research  and  development  services  under  the  Valeant  Agreement.  The  completion  of  the  final
deliverable under the Valeant Agreement represents the end of our estimated expected period of performance, as we will have no further contractual obligation to perform research and
development services under the Valeant Agreement, and therefore the earnings process will be complete. The expected period of performance was initially estimated to be a 48 month
period, starting in December 2008, upon receipt of the $40.0 million upfront payment, and ending in November 2012. During the year ended December 31, 2012, we extended the end of
the revenue recognition period for the Valeant Agreement from November 2012 to November 2013 and during the three month period ended March 31, 2013, we further extended the end
of the revenue recognition period for the agreement from November 2013 to December 2014 due to changes in the estimated timing of completion of certain research and development
activities under the agreement. All deferred revenue under the Valeant Agreement was completely recognized as of December 31, 2014.

Third-Party Research Agreements. In addition to our own research and development resources, we may use unrelated third-party vendors, including universities and independent
research companies, to assist in our research and development activities. These vendors provide a range of research and development services to us, including clinical and bio-equivalency
studies. We generally sign agreements with these vendors which establish the terms of each study performed by them, including, among other things, the technical specifications of the
study, the payment schedule, and timing of work to be performed. Third-party researchers generally earn payments either upon the achievement of a milestone, or on a pre-determined
date, as specified in each study agreement. We account for third-party research and development expenses as they are incurred according to the terms and conditions of the respective
agreement for each study performed, with an accrued expense at each balance sheet date for estimated fees and charges incurred by us, but not yet billed to us. We monitor aggregate
actual payments and compare them to the estimated provisions to assess the reasonableness of the accrued expense balance at each quarterly balance sheet date.

Share-Based Compensation. We recognize the grant date fair value of each option and restricted share over its vesting period. Options and restricted shares granted under the
2002 Plan generally vest over a three or four year period and generally have a term of ten years. We estimate the fair value of each stock option award on the grant date using the Black-
Scholes-Merton  option-pricing  model,  wherein  expected  volatility  is  based  on  historical  volatility  of  our  common  stock.  We  base  the  expected  term  calculation  on  the  “simplified”
method described in SAB No. 107, Share-Based Payment and SAB No. 110, Share-Based Payment, because it provides a reasonable estimate in comparison to our actual experience. We
base the risk-free interest rate on the U.S. Treasury yield in effect at the time of grant for an instrument with a maturity that is commensurate with the expected term of the stock options.
The dividend yield is zero as we have never paid cash dividends on our common stock, and have no present intention to pay cash dividends. During the year ended December 31, 2014,
we granted shares of restricted stock that vested upon the achievement of certain stock price performance criteria during the year ended December 31, 2015. We valued these awards
using a Monte Carlo simulation.

Income  Taxes.  We  are  subject  to  U.S.  federal,  state  and  local  income  taxes,  Netherlands  income  tax  and  Taiwan  R.O.C.  income  taxes.  We  create  a  deferred  tax  asset,  or  a

deferred tax liability, when we have temporary differences between the financial statement carrying values (GAAP) and the tax bases of our assets and liabilities.

Fair Value of Financial Instruments. Our deferred compensation liability is carried at the value of the amount owed to participants, and is derived from observable market data
by reference to hypothetical investments. The carrying values of other financial assets and liabilities such as accounts receivable, accounts payable and accrued expenses approximate
their fair values due to their short-term nature.

49

 
 
 
 
 
 
 
 
 
Contingencies. In the normal course of business, we are subject to loss contingencies, such as legal proceedings and claims arising out of our business, covering a wide range of
matters,  including, among others, patent  litigation,  stockholder  lawsuits, and product and clinical  trial  liability.  In accordance  with FASB ASC Topic 450 - Contingencies,  we record
accrued loss contingencies when it is probable a liability will be incurred and the amount of loss can be reasonably estimated and we do not recognize gain contingencies until realized.

The  estimated  fair  value  of  the  in-process  research  and  development  and  identifiable  intangible  assets  acquired  in  the  Tower  acquisition  was  determined  using  the  “income
approach,” which is a valuation technique that provides an estimate of the fair value of an asset based on market participant expectations of the cash flows an asset would generate over its
remaining useful life. Some of the more significant assumptions inherent in the development of those asset valuations include the estimated net cash flows for each year for each asset or
product (including net revenues, cost of sales, research and development costs, selling and marketing costs and working capital/asset contributory asset charges), the appropriate discount
rate  to  select  in  order  to  measure  the  risk  inherent  in  each  future  cash  flow  stream,  the  assessment  of  each  asset’s  life  cycle,  the  potential  regulatory  and  commercial  success  risks,
competitive trends impacting the asset and each cash flow stream as well as other factors. The discount rates used to arrive at the present value at the Tower acquisition date of currently
marketed products was 15%. For in-process research and development, the discount rate used was 16% to reflect the internal rate of return and incremental commercial uncertainty in the
cash flow projections. No assurances can be given that the underlying assumptions used to prepare the discounted cash flow analysis will not change. For these and other reasons, actual
results may vary significantly from estimated results.

Goodwill .  In  accordance  with  FASB  ASC  Topic  350,  "Goodwill  and  Other  Intangibles",  rather  than  recording  periodic  amortization  of  goodwill,  goodwill  is  subject  to  an
annual assessment for impairment by applying a fair-value-based test. Under FASB ASC Topic 350, if the fair value of the reporting unit exceeds the reporting unit’s carrying value,
including  goodwill,  then  goodwill  is  considered  not  impaired,  making  further  analysis  not  required.  We  consider  each  of  our  Impax  Generics  division  and  Impax  Specialty  Pharma
division operating segments to be a reporting unit, as this is the lowest level for each of which discrete financial information is available. We attribute approximately $60.2 million of
goodwill to the Impax Specialty Pharma division and approximately $150.0 million of goodwill to the Impax Generics division. We concluded the carrying value of goodwill was not
impaired as of December 31, 2015 and 2014, as the fair value of the Impax Specialty Pharma division and the Impax Generics division exceeded their respective carrying values at each
date. We perform our annual goodwill impairment test in the fourth quarter of each year. We estimate the fair value of the Impax Specialty Pharma division and the Impax Generics
division using a discounted cash flow model for both the reporting unit and the enterprise, as well as earnings and revenue multiples per common share outstanding for enterprise fair
value. In addition, on a quarterly basis, we perform a review of our business operations to determine whether events or changes in circumstances have occurred that could have a material
adverse effect on the estimated fair value of each reporting unit, and thus indicate a potential impairment of the goodwill carrying value. If such events or changes in circumstances were
deemed  to  have  occurred,  we  would  perform  an  interim  impairment  analysis,  which  may  include  the  preparation  of  a  discounted  cash  flow  model,  or  consultation  with  one  or  more
valuation specialists, to analyze the impact, if any, on our assessment of the reporting unit’s fair value. To date, we have not deemed there to be any significant adverse changes in the
legal, regulatory or business environment in which we conduct our operations.

Consolidated  total  revenues  for  the  year  ended  December  31,  2015  increased  by  44%  or  $264.5  million  to  $860.5  million,  compared  to  $596.0  million  for  the  year  ended
December 31, 2014. The increase in consolidated total revenues during 2015 was primarily due to the addition of product revenues from our acquisition of Tower and increased sales of
diclofenac sodium gel and the addition of sales from Rytary® and 14 generic products launched in 2015. The year-over-year increase in revenue was partially offset by the absence of
authorized generic Renvela® sales during 2015, for which there were sales during the prior year. Product volumes (including from acquisitions) increased revenues by approximately
36.0%, while product selling price decreased revenues by approximately 4%, in each case compared to the prior year. New product launches increased revenues by approximately 12%
compared to the prior year.

Revenues  from  our  Impax  Generics  division  increased  by  $161.9  million  during  2015,  as  compared  to  the  prior  year,  driven  primarily  by  the  increase  in  revenues  from  the
Tower acquisition and increased sales volume from diclofenac sodium gel, partially offset by the absence of sales of authorized generic Renvela® during 2015, for which there were sales
during the prior year. Revenues from the Impax Specialty Pharma division increased by $102.6 million during 2015, as compared to the prior year, as a result of the launch of Rytary® as
well as product volumes from the Tower acquired companies during 2015.

Net income for the year ended December 31, 2015 was $39.0 million, a decrease of $18.4 million as compared to $57.4 million for the year ended December 31, 2014. The
decrease was primarily attributable to lower margins from product sales and higher operating expenses, in each case compared to the prior year. We also experienced higher amortization
and impairment charges related to intangible assets, higher severance costs related to the restructuring of our packaging and distribution facilities announced on June 30, 2015 as well as
costs related to the fair value of inventory resulting from the Tower acquisition. Such increased costs were partially offset by reduced Hayward facility remediation costs during 2015. In
addition, we had a loss on debt extinguishment related to the repayment of our term loan with Barclays, as well as higher interest expense related to the Barclays term loan and to our
convertible notes and a net loss on the change in the fair value of our derivatives in connection with the call spread overlay on our convertible notes, in each case during 2015 for which
we did not have similar  charges during the prior year period. The decrease  in net income  during 2015 was partially  offset by the gain of $45.6 million from the sale of our rights to
Daraprim® in 2015.

Revenues
Total  revenues  for  the  Impax  Generics  division  for  the  year  ended  December  31,  2015  were  $710.9  million,  an  increase  of  29%  from  the  same  period  in  2014,  principally
resulting from the addition of product revenue from the Tower acquisition as well as increased sales from diclofenac sodium gel and 14 generic products launched during 2015 including
Lamotrigine ODT, partially offset by the absence of revenues from sales of authorized generic Renvela® during 2015, for which there were sales during the prior year.

Cost of Revenues
Cost of revenues was $450.0 million for the year ended December 31, 2015, an increase of $189.5 million compared to cost of revenues of $260.5 million in the prior year. In
addition to increased costs related to higher product sales, cost of revenues in the current period increased due to higher product amortization, intangible asset impairment charges, costs
related  to  the  step-up  to  fair  value  of  inventory  in  connection  with  the  Tower  acquisition,  as  well  as  closing  and  severance  costs  related  to  the  restructuring  of  our  packaging  and
distribution operations announced on June 30, 2015. This increase was partially offset by lower remediation costs, as compared to the prior year.

Gross Profit
Gross profit for the year ended December 31, 2015 was $260.9 million, or approximately 37% of total revenues, as compared to $288.6 million, or approximately 53% of total
revenues, in the prior year. The decline in gross profit and gross margin was primarily driven by product mix. Sales during 2014 of authorized generic Renvela®, a high margin product,
for which we had no sales in 2015, were replaced by lower margin products from the Tower acquisition and sales of diclofenac sodium gel which carry a 50% profit share with our third
party partner.

Research and Development Expenses
Total research and development expenses for the year ended December 31, 2015 were $58.8 million, an increase of 44%, as compared to the prior year. Generic research and
development expenses increased in 2015 compared to the prior year, primarily due to the addition of research and development projects from the Tower acquisition including intangible
asset impairment charges of $6.4 million.

Patent Litigation Expenses
Patent litigation expenses for the year ended December 31, 2015 were $2.9 million, a decrease of 45%, as compared to the prior year. The decrease in patent litigation expenses

in 2015 of $2.4 million compared to the prior year was the result of legal activity related to several cases in the prior year for which there was no corresponding activity in 2015.

Selling, General and Administrative Expenses
Selling, general and administrative expenses for the year ended December 31, 2015 were $29.6 million, a 73% increase over the prior year. The increase during 2015 from the
prior year was primarily the result of an increase in accounts receivable reserves and an increase in penalties paid to customers for delays or failures to supply product and the addition of
the selling, general and administrative expenses from the Tower acquisition that were partially offset by lower personnel expense during 2015.

Revenues
Total revenues for the Impax Specialty Pharma division were $149.5 million for the year ended December 31, 2015, an increase of $102.6 million compared to the year ended

December 31, 2014, due to revenues from the launch of Rytary® and revenues from the Tower acquisition during 2015.

Cost of Revenues
Cost of revenues was $58.0 million for the year ended December 31, 2015, an increase of $35.1 million over the prior year. In addition to increased costs related to increased
product  sales,  cost  of  revenues  increased  in  2015  due  to  higher  amortization  and  costs  related  to  the  step-up  to  fair  value  of  inventory,  each  incurred  in  connection  with  the  Tower
acquisition. This increase was partially offset by a reserve included in the cost of revenues during 2014 for pre-launch inventory related to Rytary® as a result of a Complete Response
Letter received in 2014, for which there were no similar amounts included in cost of revenues in 2015.

Gross Profit
Gross profit  for the year ended December  31, 2015 was $91.5 million  or approximately  61% of total revenues,  as compared  to $24.0 million  or approximately  51% of total
revenues in the prior year. The revenue from Rytary® and revenue from the Tower acquisition were the primary drivers of the increase in gross profit compared to the prior year. This
increase during 2015 was partially offset by a reserve included in the cost of revenues during 2014 for pre-launch inventory related to Rytary® as a result of a Complete Response Letter
received in 2014, for which there were no similar amounts included in cost of revenues in 2015.

Research and Development Expenses
Total research and development expenses for the year ended December 31, 2015 were $18.1 million, a decrease of 52%, as compared to $37.7 million in the prior year. The
decrease was primarily driven by a reduction in research and development expenses related to our branded initiatives and decreased costs related to reduced personnel compared to 2014
due to the restructuring and related reduction in workforce primarily in our research and development organization during the quarter ended December 31, 2014. In addition, research and
development  expense  during  2014  included  a  $2.0  million  upfront  fee  paid  to  Durect  under  an  agreement  to  acquire  the  exclusive  worldwide  rights  to  develop  and  commercialize
Durect’s investigational transdermal bupivacaine patch for the treatment of pain associated with post-herpetic neuralgia, for which there was no comparable payment made in 2015.

Patent Litigation Expenses
Patent litigation expenses for the year ended December 31, 2015 were $1.6 million, an increase of $1.1 million compared to the prior year amount of $0.5 million. The increase

was the result of legal activity related to several cases in 2015 for which there was no corresponding activity in the prior year.

Selling, General and Administrative Expenses
Selling, general and administrative expenses were $52.4 million in the year ended December 31, 2015, an increase of $9.1 million as compared to $43.3 million in the prior year.
The increase was primarily driven by an increase in advertising and promotion expenses to support the launch of Rytary® and related salesforce expansion as well as selling expenses
from the Tower acquisition.

General and Administrative Expenses
General and administrative expenses for the year ended December 31, 2015 were $119.2 million, a $40.3 million increase, as compared to $78.9 million in the prior period. The
increase  was  principally  driven  by  higher  business  development  expenses,  the  majority  of  which  was  transaction  and/or  integration  activities  related  to  the  Tower  acquisition,  the
inclusion of general and administrative expenses from the Tower acquisition, increased finance and information technology expenses as well as higher equity based compensation, in each
case compared to the prior year. The Tower-related general and administrative expenses included $2.4 million in employee severance costs related to the acquisition.

Other Income, Net
Other income, net of $0.4 million  in the year  ended December  31, 2015, was consistent  with the prior  year, primarily  related  to our sale  of an ANDA during 2015 for $1.0

million. Partially offsetting this income in 2015 was a fixed asset impairment, for which there was no corresponding charge in the prior year.

Loss on debt extinguishment
During the year ended December 31, 2015, we recognized a $16.9 million loss on the extinguishment of debt related to unamortized debt issuance costs upon the repayment of

our term loan with Barclays, for which there was no comparable loss in the prior year.

Gain on sale of asset
During the year ended December 31, 2015, we recognized a gain of $45.6 million on the sale of our rights to Daraprim®, for which there was no comparable amount in the prior

year.

Net change in fair value of derivatives
During the year ended December 31, 2015, we recognized a $13.0 million expense from the net change in the fair value of our derivative instruments related to our convertible

senior notes at June 30, 2015 compared to December 8, 2015. We did not incur a corresponding charge in the prior year. See “Note 8. Derivatives” for additional information.

Interest Income
Interest income in the year ended December 31, 2015 was $1.0 million, a slight decrease from 2014.

Interest Expense
Interest expense in the year ended December 31, 2015 was $27.3 million, primarily related to interest expenses on debt issued in connection with the Tower acquisition as well
as interest accrued on our outstanding convertible notes which were issued in 2015 and for which we did not incur similar expense during the prior year. Interest expense in 2015 also
included $2.3 million in commitment fees incurred prior to the closing of the Tower acquisition, for which there were no corresponding fees in the prior year.

Income Taxes
During the year ended December 31, 2015, we recorded an aggregate tax provision of $20.4 million for U.S. domestic income taxes and for foreign income taxes, a decrease of
$12.8 million  compared  to an aggregate  tax  provision of $33.2 million  we recorded  during the  prior  year.  The decrease  in the  tax provision  during 2015 compared  to the prior  year
resulted from lower income before taxes in the year ended December 31, 2015.  The effective tax rate decreased to 34% for the year ended December 31, 2015 compared to 37% for the
year ended December 31, 2014.  The 2015 effective tax rate was lower due to a change in the timing and mix of U.S. and foreign income. Other contributing factors to the rate fluctuation
included favorable book-tax differences for federal tax benefits, including the R&D credit and domestic manufacturing deduction, on the Tower entities which we acquired in 2015.

Consolidated total revenues for the year ended December 31, 2014 increased $84.5 million, or 17%, as compared to the year ended December 31, 2013. New product launches
increased revenues during the year ended December 31, 2014 by $84.4 million, or 17%, compared to 2013, primarily related to sales of our authorized generic Renvela® tablets and
generic Solaraze®. Decreased product volumes (excluding new product launches) decreased revenues during the year ended December 31, 2014 by $20.3 million, or 4%, compared to
2013, while selling price and product mix increased revenues by $20.4 million, or 4%, compared to 2013. Revenues from our Impax Generics division increased $150.7 million during
the year ended December 31, 2014, as compared to 2013, driven primarily by sales of our authorized generic Renvela® tablets, in addition to higher sales of our Digoxin and generic
Solaraze® products. Revenues from our Impax Specialty Pharma division decreased $66.2 million in 2014 as compared to 2013, as a result of a decline in sales of our Impax-labeled
branded Zomig® products. In May 2013, our exclusivity period for branded Zomig® tablets and orally disintegrating tablets expired and we launched authorized generic versions of those
products in the United States.

Net income for the year ended December 31, 2014 was $57.4 million, a decrease of $43.9 million as compared to $101.3 million for the year ended December 31, 2013. The
decrease from 2013 was primarily attributable to a $102.0 million gain in connection with the settlement of litigation with Endo which we recorded as “Other Income” in the three month
period ended March 31, 2013, as well as the receipt of a $48.0 million payment from Shire in the three month period ended March 31, 2013, in connection with the settlement of litigation
and for which there were no corresponding gains or payments during the year ended December 31, 2014 and which were both partially offset by the tax consequences of the settlements.
Also contributing to the change in net income was an increase in Impax Generics division revenue related to increased sales on several of our higher margin products, partially offset by a
decline in sales of our Impax-labeled branded Zomig® products, as discussed above.

Revenues
Total revenues for the Impax Generics division for the year ended December 31, 2014, were $549.1 million, an increase of 38% from 2013, resulting from increases in Impax

Generics sales, net, and Other Revenues, as discussed below.

Impax Generics sales, net, were $528.5 million for the year ended December 31, 2014, an increase of 38% from 2013, primarily as a result of sales of our authorized generic
Renvela® tablets launched during the three month period ended June 30, 2014, higher sales of our Digoxin products and the launch of our generic Solaraze® during the fourth quarter of
2013.

Rx Partner revenues were $14.1 million for the year ended December 31, 2014, an increase of 21% over the prior year resulting primarily from a $3.3 million profit share earned

pursuant to our agreement with Perrigo related to the launch of generic Astepro®.  

Other Revenues were $6.5 million  for the year ended  December  31, 2014, with the increase  from  the prior year  primarily  resulting  from  the receipt  of a milestone  payment

pursuant to our agreement with a third-party pharmaceutical company.

Cost of Revenues
Cost of revenues was $260.5 million for the year ended December 31, 2014 and $253.8 million for the prior year, an increase of $6.6 million compared to the prior year. Cost of
revenues increased due to increased revenue as discussed above. Such increases were partially offset by $10.3 of higher intangible asset impairment charges taken in the prior year, as
discussed in “Note 12. Goodwill and Intangible Assets” and $13.0 million more in inventory reserves related to discontinued product and other reserves for pre-launch inventory taken
during the year ended December 31, 2013.

Gross Profit
Gross profit for the year ended December 31, 2014 was $288.6 million, or approximately 53% of total revenues, as compared to $144.5 million, or approximately 36% of total
revenues, in the prior year. Gross profit as a percent of total revenues increased in 2014 as compared to the prior year largely due to favorable product contribution from higher margin
products, including Renvela®, as well as the other items noted above under Cost of Revenues.

Research and Development Expenses
Total research and development expenses for the year ended December 31, 2014 were $40.9 million, a decrease of 1%, as compared to the same period of the prior year. Generic
research and development expenses decreased in 2014 compared to the prior year primarily due to lower external development spending of $5.8 million and a decrease in professional
fees of $0.5 million. In addition, during 2013, we incurred an intangible impairment charge of $0.8 million, for which there was no comparable charge in 2014. These decreases were
partially offset by an overall increase of $4.6 million associated with internal development spending and an increase in personnel costs of $2.0 million, which included $0.7 million of
severance expense associated with the reduction in workforce primarily related to our research and development organization during the fourth quarter ended December 31, 2014.

Patent Litigation Expenses
Patent litigation expenses for the year ended December 31, 2014 were $5.3 million, a decrease of 68%, as compared to the prior year. The decrease in patent litigation expenses

in 2014 of $11.2 million compared to the prior year was the result of legal activity related to several cases in 2013 for which there was no corresponding activity in 2014.

Selling, Gene ral and Administrative Expenses
Selling, general and administrative expenses for the year ended December 31, 2014 were $17.1 million, a 3% decrease over the prior year. The decrease from the prior year was
primarily due to $2.9 million in lower customer claims relating to failure to supply products in accordance with their contractual terms. This decrease was partially offset by an increase in
personnel  expense  of  $2.5  million  primarily  related  to  severance  expenses  associated  with  the  reduction  in  workforce  primarily  related  to  our  research  and  development  organization
during the fourth quarter ended December 31, 2014.

Revenues
Total revenues  for the Impax Specialty  Pharma division were $47.0 million  for the year ended December  31, 2014, a decrease  of $66.2 million  compared  to the year ended
December 31, 2013, due to lower sales of our Impax-labeled branded Zomig® products which we began selling during the year ended December 31, 2012. In May 2013, our exclusivity
period for branded Zomig® tablets and orally disintegrating tablets expired and we launched authorized generic versions of those products in the United States. We continue to sell the
branded Zomig® nasal spray.

Other Revenues for the year ended December 31, 2014 were relatively consistent with Other Revenues for the prior year, representing the recognition of an initial $10.0 million
upfront payment we received in June 2010 under a Development and Co-Promotion Agreement with Endo Pharmaceuticals, Inc. During 2014, we recognized this upfront payment as
revenue on a straight-line basis over our expected period of performance during the development period, which we estimated to be the 112 month period ending September 2019.

Cost of Revenues
Cost of revenues were $22.9 million for the year ended December 31, 2014, a decrease of $35.4 million over the prior year, commensurate with a reduction in revenues and

lower amortization costs related to the loss of exclusivity on branded Zomig® tablets and orally disintegrating tablets in May 2013.

Gross Profit
Gross profit for the year ended December 31, 2014 was $24.0 million, a decrease of $30.8 million over the prior year, commensurate with a reduction in revenues and other costs

noted above.

Re search and Development Expenses
Total research and development expenses for the year ended December 31, 2014 were $38.2 million, an increase of 39%, as compared to $27.5 million in the prior year. The
increase was primarily driven by an increase in research and development expenses related to our branded initiatives and increased personnel costs of $2.0 million, in each case compared
to  2013.  We  also  paid  a  $2.0  million  upfront  fee  to  Durect  under  an  agreement  to  acquire  the  exclusive  worldwide  rights  to  develop  and  commercialize  Durect’s  investigational
transdermal bupivacaine patch for the treatment of pain associated with PHN, referred to as IPX239, for which there was no corresponding charge in 2013.

Selling, General and Administrative Expenses
Selling, general and administrative expenses were $43.3 million in the year ended December 31, 2014, a decrease of $1.6 million as compared to $44.9 million in the prior year.
The decrease compared to 2013 was primarily driven by a $1.4 million reduction in advertising and promotion expenses for Zomig® due to loss of exclusivity of branded Zomig® tablets
and  orally  disintegrating  tablets  during  2013,  a  $1.0  million  reduction  in  legal  support  of  brand  licensing  initiatives  and  a  $0.9  million  expense  due  to  a  reduction  in  the  sales  force
workforce. These reductions were partially offset by a $1.1 million increase in advertising and promotion expenses for pre-launch support for Rytary™ and increased personnel costs of
$0.5 million during 2014.

General and Administrative Expenses
General and administrative expenses for the year ended December 31, 2014 were $78.9 million, a $21.3 million increase, as compared to $57.7 million in 2013. The increase
was principally driven by increases in business development expenses of $10.2 million, information technology expenses of $3.8 million, legal expenses of $3.6 million, and net other
costs of $3.5 million during 2014.

Other Income (Expense), Net
Other income, net of $0.3 million in the year ended December 31, 2014, a decrease of $152.1 million from the prior year, primarily due to a $102.0 million gain during 2013 in
connection with the settlement of litigation with Endo which we recorded as Other Income in the three month period ended March 31, 2013, as well as a $48.0 million payment received
from Shire in connection with the settlement of litigation in the three month period ended March 31, 2013, for which there were no comparable charges during 2014. In addition, we
recorded a $3.0 million gain in connection with the settlement of litigation in Other Income during the three month period ended June 30, 2013, for which there was no comparable charge
during 2014. Partially offsetting this income in the prior year period was a $0.9 million loss on disposal of software in the three month period ended March 31, 2013.

Interest Income
Interest income in the year ended December 31, 2014 was $1.5 million, a slight increase from 2013.

Interest Expense
Interest expense in the year ended December 31, 2014 was less than $0.1 million, a decrease of $0.4 million from 2013, resulting from a reduction in the interest related to our

liability for uncertain tax positions.

Income Taxes
During the year ended December 31, 2014, we recorded an aggregate tax provision of $33.2 million for U.S. domestic income taxes and for foreign income taxes, a decrease of
$12.5  million  compared  to  an  aggregate  tax  provision  of  $45.7  million  we  recorded  during  the  prior  year.  The  decrease  in  the  tax  provision  during  2014  compared  to  the  prior  year
resulted from lower income before taxes in the year ended December 31, 2014 as compared to the prior year. The effective tax rate increased to 36% for the year ended December 31,
2014 as compared  to 31% for the year ended December 31, 2013. The 2013 effective  tax rate  was lower due to two years of the federal  tax benefit  being recorded  as a result of the
legislation’s enactment date. In addition, the 2014 effective tax rate was affected by losses incurred in certain zero rate jurisdictions, for which there were no corresponding costs in the
prior year period.

Liquidity and Capital Resources
We generally fund our operations with cash from operations; however, we have used proceeds from the sale of debt and equity securities in the past. Our cash from operations

consists primarily of the proceeds from the sales of our products and services.

We expect to incur significant operating expenses, including research and development activities and patent litigation expenses, for the foreseeable future. In addition, we are
generally required to make cash expenditures to manufacture or acquire finished product inventory in advance of selling the finished product to our customers and collecting payment,
which may result in significant periodic uses of cash. We believe our existing cash and cash equivalents, together with cash expected to be generated from operations, and our revolving
line  of  credit  will  be  sufficient  to  meet  our  financing  requirements  through  the  next  12  months.  We  may,  however,  seek  additional  financing  through  alliance,  collaboration,  and/or
licensing  agreements,  as  well  as  from  the  debt  and  equity  capital  markets  to  fund  capital  expenditures,  research  and  development  plans,  potential  acquisitions,  and  potential  revenue
shortfalls due to delays in new product introductions or otherwise. We cannot assure that such financing will be available on favorable terms, or at all.

Cash and Cash Equivalents
At December 31, 2015, we had $340.4 million in cash and cash equivalents, an increase of $125.5 million as compared to $214.9 million at December 31, 2014. As more fully
discussed below, the increase in cash and cash equivalents during the year ended December 31, 2015 was driven by $521.4 million of net cash provided by financing activities and $71.9
million of net cash provided by operating activities, partially offset by net cash used in investing activities of $467.5 million.

Cash Flows
Year Ended December 31, 2015 Compared to Year Ended December 31, 2014.

Net cash provided by operating activities for the year ended December 31, 2015 was $71.9 million, an increase of $39.1 million as compared to the prior year $32.8 million net
cash provided by operating activities. The significant factors contributing to the increased cash flow from operations during 2015 included increased net profit sharing accruals driven by
the product sales mix experienced in the fourth quarter of 2015, increased amortization and impairment charges related to the Tower acquisition, increased share based compensation
expense, as well as an add back for the write off of deferred financing costs which occurred in the second quarter of 2015. These increases were partially offset by reduced net income
which was largely driven by the absence of sales of authorized generic Renvela® and a deduction for the gain on sale of our rights to Daraprim® during 2015.

Net cash used in investing activities for the year ended December 31, 2015 was $467.5 million as compared to $16.6 million for the prior year. The period over period increase
in net cash used was due primarily to cash used to fund the Tower acquisition purchase price of $691.3 million (net of cash acquired in the acquisition), partially offset by a change in
purchases of short term investments and a change in maturities of investments of $170.8 million with those cash proceeds used in part to fund the Tower acquisition. Net cash flow from
investing activities also included $55.5 million in proceeds from the sale of our rights to Daraprim® during 2015.

Net cash provided by financing activities for the year ended December 31, 2015 was $521.4 million, representing an increase of $507.0 million as compared to the prior year
$14.4 million of net cash provided by financing activities. The year-over-year increase in net cash provided by financing activities was due to the sales of our convertible notes and related
bond hedge activities. Please refer to “Outstanding Debt Obligations” below for further details.

Cash Flows - Year Ended December 31, 2014 Compared to Year Ended December 31, 2013.

Net cash provided by operating activities for the year ended December 31, 2014 was $32.8 million, a decrease of $117.1 million as compared to the prior year $149.9 million net
cash provided by operating activities. The period-over-period change in net cash provided by operating activities was driven by lower net income as a result of the payments received in
connection with various legal settlements in 2013 as well as an increased investment in working capital. The increased net investment in working capital in 2014 compared to 2013 was
largely driven by accounts receivable and inventory. The 2014 increase in accounts receivable was primarily due to increased sales in the fourth quarter of 2014 compared to the fourth
quarter  of  2013. The  increase  in  accounts  receivable  in  2013  was due  to  timing  of  cash  collections  as  we experienced  some  delays  in  payments.  The  2014 increase  in  inventory  was
incurred to support the 2015 launch of Rytary™ as well as to support commercial activities on certain backordered products.

Net cash used in investing activities for the year ended December 31, 2014 was $16.6 million as compared to $115.9 million for the prior year. The decrease in cash used in
investing  activities  during  2014  was  due  primarily  due  to  a  year-over-year  increase  in  cash  provided  by  net  maturities  of  short-term  investments  of  $109.4  million.  This  change  was
caused by the receipt of over $150 million in legal settlements in 2013 and our subsequent investment in short-term investments. Purchases of property, plant and equipment for the year
ended December 31, 2014 were $29.9 million as compared to $32.8 million for the prior year, due to reduced spending on the Taiwan manufacturing facility, which was partially offset
by increased remediation related projects.

Net cash provided by financing activities for the year ended December 31, 2014 was $14.4 million, representing an increase of $5.4 million as compared to the prior year $9.0
million  of  net  cash  provided  by  financing  activities.  The  year-over-year  increase  in  net  cash  provided  by  financing  activities  was  due  to  a  $2.9  million  increase  in  the  cash  proceeds
received from the exercise of stock options and contributions to the employee stock purchase plan and a $2.6 million increase in tax benefits related to the exercise of employee stock
options.

Off-Balance Sheet Arrangements

We did not have any off-balance sheet arrangements as of December 31, 2015 and 2014.

Outstanding Debt Obligations

2% Convertible Senior Notes due June 2022

On June 30, 2015, we issued an aggregate principal amount of $600.0 million of 2.00% Convertible Senior Notes due June 2022 (the “Notes”) in a private placement offering,
which are our senior unsecured obligations. The Notes were issued pursuant to an Indenture dated June 30, 2015 (the “Indenture”) between us and Wilmington Trust, N.A., as trustee.
The Indenture includes customary covenants and sets forth certain events of default after which the Notes may be due and payable immediately. The Notes will mature on June 15,
2022, unless earlier redeemed, repurchased or converted. The Notes bear interest at a rate of 2.00% per year, and interest is payable semiannually in arrears on June 15 and December
15 of each year, beginning on December 15, 2015.

The conversion rate for the Notes is initially set at 15.7858 shares per $1,000 of principal amount, which is equivalent to an initial conversion price of $63.35 per share of our
common stock. If a Make-Whole Fundamental Change (as defined in the Indenture) occurs or becomes effective prior to the maturity date and a holder elects to convert its Notes in
connection with the Make-Whole Fundamental Change, we are obligated to increase the conversion rate for the Notes so surrendered by a number of additional shares of our common
stock as prescribed in the Indenture. Additionally, the conversion rate is subject to adjustment in the event of an equity restructuring transaction such as a stock dividend, stock split,
spinoff, rights offering, or recapitalization through a large, nonrecurring cash dividend (“standard antidilution provisions,” per ASC 815-40 – Contracts in Entity’s Own Equity).

The Notes are convertible at the option of the holders at any time prior to the close of business on the business day immediately preceding December 15, 2021 only under the

following circumstances:

(i)

(ii)

If  during  any  calendar  quarter  commencing  after  the  quarter  ending  September  30,  2015  (and  only  during  such  calendar  quarter)  the  last  reported  sale  price  of  our
common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately
preceding calendar quarter is greater than 130% of the conversion price on each applicable trading day; or
If during the five business day period after any 10 consecutive trading day period (the “measurement period”) in which the trading price per $1,000 of principal amount
of Notes for each trading day of the measurement period was less than 98% of the product of the last report sale price of our common stock and the conversion rate on
each such trading day; or

(iii) Upon the occurrence of corporate events specified in the Indenture.

On or after December 15, 2021 until the close of business on the second scheduled trading day immediately preceding the maturity date, the holders may convert their Notes at
any time, regardless of the foregoing circumstances. We may satisfy our conversion obligation by paying or delivering, as the case may be, cash, shares of our common stock, or a
combination of cash and shares of our common stock, at our election and in the manner and subject to the terms and conditions provided in the Indenture.

Concurrently with the offering of the Notes and using a portion of the proceeds from the sale of the Notes, we entered into a series of convertible note hedge and warrant
transactions (the “Note Hedge Transactions” and “Warrant Transactions”) which are designed to reduce the potential dilution to our stockholders and/or offset the cash payments we are
required  to  make  in  excess  of  the  principal  amount  upon  conversion  of  the  Notes.  The  Note  Hedge  Transactions  and  Warrant  Transactions  are  separate  transactions,  in  each  case,
entered into by us with a financial institution and are not part of the terms of the Notes. These transactions will not affect any holder’s rights under the Notes, and the holders of the
Notes have no rights with respect to the Note Hedge Transactions and Warrant Transactions. See “Note 8. Derivatives” and “Note 15. Stockholders’ Equity” for additional information.

At the June 30, 2015 issuance date of the Notes, we did not have the necessary number of authorized but unissued shares of its common stock available to settle the conversion
option of the Notes in shares of our common stock. Therefore, in accordance with guidance found in ASC 470-20 – Debt with Conversion and Other Options (“ASC 470-20”) and ASC
815-15 –  Embedded  Derivatives  (“ASC 815-15”),  the conversion  option  of the  Notes was deemed  an embedded  derivative  requiring  bifurcation  from  the  Notes (host  contract)  and
separate accounting as a derivative liability. The fair value of the conversion option derivative liability at June 30, 2015 was $167.0 million, which was recorded as a reduction to the
carrying value of the debt. This debt discount will be amortized to interest expense over the term of the debt using the effective interest method. Although we received stockholder
approval on December 8, 2015 to amend our Restated Certificate of Incorporation to increase the number of authorized shares of our common stock (which amendment has occurred),
the debt discount related to the conversion option derivative liability remains and continues to be amortized to interest expense. The effect of the increase in the authorized number of
shares of our common stock on the derivative liability is discussed in “Note 8. Derivatives.”

In connection with the issuance of the Notes, we incurred approximately $18.7 million of debt issuance costs for banking, legal and accounting fees and other expenses during
the year ended December 31, 2015. This was also recorded on our balance sheet as a reduction to the carrying value of the debt, in accordance with our early adoption of Accounting
Standards Update (“ASU”) No. 2015-03 – Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-03”), and will be amortized to interest expense over the term of the debt
using the effective interest method.

65

 
 
 
 
 
 
 
 
 
 
 
 
 
For the year ended December 31, 2015, we recognized $16.3 million of interest expense related to the Notes, of which $6.0 million was cash and $10.3 million was non-cash
accretion of the debt discounts recorded. As the Notes mature in 2022, such interest has been classified as long-term debt on our consolidated balance sheet, with a carrying value of
approximately $424.6 million as of December 31, 2015.

Royal Bank of Canada $100.0 Million Revolver

On August 4, 2015, we entered into a senior secured revolving credit facility (the “Revolving Credit Facility”) of up to $100 million, pursuant to a credit agreement, by and
among  us,  the  lenders  party  thereto  from  time  to  time  and  Royal  Bank  of  Canada,  as  administrative  agent  and  collateral  agent  (the  “Revolving  Credit  Facility  Agreement”).  The
Revolving Credit Facility is available for working capital and other general corporate purposes. Borrowings under the Revolving Credit Facility will accrue interest at a rate equal to
LIBOR or the base rate, plus an applicable margin. The applicable margin may be increased or reduced by 0.75% based on our total net leverage ratio. The Revolving Credit Facility
will mature on August 4, 2020. No borrowings were drawn from the Revolving Credit Facility during the year ended December 31, 2015.

Loss on Early Extinguishment of Debt – Barclays $435.0 Million Term Loan

In connection with the acquisition of Tower during the first quarter of 2015, we entered into a $435.0 million senior secured term loan facility (the “Term Loan”) and a $50.0
million  senior secured revolving credit  facility  (the “Barclays  Revolver” and collectively  with the Term Loan, the “Barclays  Senior Secured Credit Facilities”),  pursuant to a credit
agreement, dated as of March 9, 2015, by and among us, the lenders party thereto from time to time and Barclays Bank PLC, as administrative and collateral agent (the “Barclays Credit
Agreement”).  In  connection  with  the  Barclays  Senior  Secured  Credit  Facilities,  we  incurred  debt  issuance  costs  for  banking,  legal  and  accounting  fees  and  other  expenses  of
approximately $17.8 million. Prior to repayment of the Term Loan on June 30, 2015, these debt issuance costs were to be amortized to interest expense over the term of the loan using
the effective interest rate method.

On June 30, 2015, we used approximately $436.4 million of the proceeds from the sale of the Notes to repay the $435.0 million of principal and approximately $1.4 million of
accrued interest due on the Term Loan under the Barclays Credit Agreement. In connection with this repayment of the loan, we recorded a loss on early extinguishment of debt of
approximately $16.9 million related to the unamortized portion of the deferred debt issuance costs during the quarter ended June 30, 2015.

For the six months ended June 30, 2015, we incurred total interest expense on the Term Loan of approximately $10.7 million, of which $9.8 million was cash and $0.9 million
was non-cash amortization of the deferred debt issuance costs. Included in the 2015 year-to-date cash interest expense of $15.8 million is approximately $2.3 million related to a ticking
fee paid to Barclays during the first quarter of 2015, prior to the funding of the Senior Secured Credit Facilities on March 9, 2015, to lock in the financing terms from the lenders’
commitment of the Term Loan until the actual allocation of the loan occurred.

Recent Accounting Pronouncements

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers” (Topic 606) regarding the accounting for and disclosures of revenue recognition, with
an effective date for annual and interim periods beginning after December 15, 2016. This update provides a single comprehensive model for accounting for revenue from contracts with
customers.  The model requires  that revenue recognized  reflect  the actual  consideration  to which the entity  expects  to be entitled  in exchange  for the goods or services  defined in the
contract, including in situations with multiple performance obligations. In July 2015, the FASB issued ASU 2015-14, “Revenue from Contracts with Customers (Topic 606): Deferral of
the Effective Date” which deferred the effective date, of the previously issued revenue recognition guidance, by one year. The guidance will be effective for annual and interim periods
beginning after December 15, 2017. We are currently evaluating the effect that this guidance may have on our consolidated financial statements.

In  April  2015,  the  FASB  issued  ASU  2015-03,  “Interest—Imputation  of  Interest  (Subtopic  835-30):  Simplifying  the  Presentation  of  Debt  Issuance  Costs”,  which  provided
guidance on the presentation requirements for debt issuance costs and debt discount and premium. The update requires that debt issuance costs related to a recognized debt liability be
presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt
issuance  costs  are  not  affected  by  the  updated  guidance.  The  updated  guidance  is  effective  for  annual  and  interim  periods  beginning  after  December  15,  2015  and  early  adoption  is
permitted for financial statements that have not been previously issued. We adopted this guidance in the three month period ended March 31, 2015, and it had no effect on our results of
operations.

66

 
 
 
 
 
 
 
 
 
 
 
 
 
In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): “Simplifying the Measurement of Inventory”, with guidance regarding the accounting for and measurement
of inventory. The update requires that inventory measured using first-in, first-out (FIFO) shall be measured at the lower of cost and net realizable value. When there is evidence that the
net realizable value of inventory is lower than its cost, the difference shall be recognized as a loss in earnings in the period in which it occurs. The guidance will be effective for annual
and interim periods beginning after December 15, 2016. We are currently evaluating the effect that this guidance may have on our consolidated financial statements.

In  August  2015,  the  FASB  issued  ASU  2015-15,  “Interest—Imputation  of  Interest  (Subtopic  835-30):  Presentation  and  Subsequent  Measurement  of  Debt  Issuance  Costs
Associated with Line-of-Credit  Arrangements” with guidance on the presentation  and measurement  of debt issuance  costs associated  with line-of -credit  arrangements.  ASU 2015-03
previously issued in April 2015 did not address the presentation or subsequent measurement of debt issuance costs related to line-of-credit arrangements. ASU 2015-15 states that the debt
issuance costs shall be presented as an asset and that such deferred debt issuance costs shall be amortized over the term of the line-of-credit arrangement, regardless of whether there are
any  outstanding  borrowings  on  the  line-of-credit  arrangement.  We  adopted  this  guidance  in  the  three  month  period  ended  September  30,  2015,  and  it  had  no  effect  on  our  results  of
operations.

In September 2015, the FASB issued ASU 2015-16, Business Combinations (Topic 805): “Simplifying the Accounting for Measurement-Period Adjustments”, with guidance
regarding the accounting for and disclosure of measurement-period adjustments that occur in periods after a business combination is consummated. This update requires that the acquirer
recognize measurement-period adjustments in the reporting period in which they are determined and, as such, eliminates the previous requirement to retrospectively account for these
adjustments.  This update also requires  an entity  to present separately  on the face of the income  statement,  or disclose  in the notes, the amount recorded  in the current-period  income
statement that would have been recorded in previous reporting periods if the adjustments had been recognized as of the acquisition date. The effective date for annual and interim periods
begins after December 15, 2016. We are currently evaluating the effect that this guidance may have on our consolidated financial statements.

In November 2015, the FASB issued ASU 2015-17, “Balance  Sheet Classification  of Deferred  Taxes”, which requires  that deferred  tax assets and liabilities  be classified  as
noncurrent in a classified statement of financial position. This update is effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods
within those fiscal years, and may be applied either prospectively to all deferred tax assets and liabilities or retrospectively to all periods presented. We elected to early-adopt this update
on a retrospective basis, which resulted in $54.8 million of current deferred tax assets being reclassified to long-term as of December 31, 2014. The adoption of this update had no effect
on our results of operations.

Item 7A.          Quantitative and Qualitative Disclosures about Market Risk

Our  cash  equivalents  and  short-term  investments  included  a  portfolio  of  high  credit  quality  securities,  including  U.S.  government  securities,  treasury  bills,  short-term
commercial paper, and highly-rated money market funds. We had no short-term investments as of December 31, 2015 and the carrying value of the portfolio at December 31, 2014
approximated the market value of the related assets. As a result of the short-term investments at December 31, 2014, the portfolio was subject to interest rate risk. Based on the average
duration of our investments as of December 31, 2014, an increase of one percentage point in interest rates would have resulted in an increase in interest income of approximately $2.4
million.

Financial instruments that potentially subject us to concentrations of credit risk consist principally of cash equivalents, short-term investments and accounts receivable. We
limit  our  credit  risk  associated  with  cash  equivalents  and  short-term  investments  by  placing  investments  with  high  credit  quality  securities,  including  U.S.  government  securities,
treasury  bills,  corporate  debt,  short-term  commercial  paper  and  highly-rated  money  market  funds.  We  limit  our  credit  risk  with  respect  to  accounts  receivable  by performing  credit
evaluations when deemed necessary. We do not require collateral to secure amounts owed to us by our customers.

As discussed above under “– Outstanding Debt Obligations,” we are party to the Revolving Credit Facility of up to $100 million, which is available for working capital and

other general corporate purposes.

We  also  issued  the  Notes  in  a  private  placement  offering  on  June  30,  2015,  which  are  our  senior  unsecured  obligations,  as  described  above  under  “Outstanding  Debt

Obligations.”

Prior to June 30, 2015, we had no derivative assets or liabilities and did not engage in any hedging activities. As a result of our June 30, 2015 issuance of the Notes described
above under “Outstanding Debt Obligations” and in “Item 15. Exhibits and Financial Statement Schedules - Note 14. Debt”, we entered into a series of convertible note hedge and
warrant  transactions  (the  “Note  Hedge  Transactions”  and  “Warrant  Transactions”)  which  are  designed  to  reduce  the  potential  dilution  to  our  stockholders  and/or  offset  the  cash
payments we are required to make in excess of the principal amount upon conversion of the Notes. See “Item 15. Exhibits and Financial Statement Schedules - Note 8. Derivatives” for
additional information.

We do not use derivative financial instruments or engage in hedging activities in our ordinary course of business and have no material foreign currency exchange exposure or
commodity  price  risks.  See  “Item  15.  Exhibits  and  Financial  Statement  Schedules  –  Note  23.  Segment  Information”  for  more  information  regarding  the  value  of  our  investment  in
Impax Laboratories (Taiwan), Inc.

We do not believe that inflation has had a significant impact on our revenues or operations to date.

Disclosure Controls and Procedures

We maintain disclosure controls and procedures (as defined in Rule 13a-15(e) of the Exchange Act) designed to ensure information required to be disclosed by us in reports we
file  or  submit  under  the  Exchange  Act  is  recorded,  processed,  summarized  and  reported  within  the  time  periods  specified  in  the  SEC’s  rules  and  forms,  and  such  information  is
accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required
disclosure.

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of
the end of the period covered by this Annual Report on Form 10-K. Based upon this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure
controls and procedures, as defined in Rule 13a-15(e) of the Exchange Act, were effective at the reasonable assurance level as of December 31, 2015.

Management Report on Internal Control Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Exchange Act Rule 13a-15(f), to provide reasonable
assurance regarding the reliability of our financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles
used in the United States (GAAP). Internal control over financial reporting includes those policies and procedures which (i) pertain to the maintenance of records, in reasonable detail, to
accurately  and  fairly  record  the  transactions  and  dispositions  of  our  assets;  (ii)  provide  reasonable  assurance  transactions  are  recorded  as  necessary  to  permit  preparation  of  financial
statements  in  accordance  with  GAAP,  and  our  receipts  and  expenditures  are  being  made  only  in  accordance  with  authorizations  of  our  management  and  directors;  and  (iii)  provide
reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets which could have a material effect on the financial statements.
Internal  control  over financial  reporting  includes the controls  themselves,  monitoring  of those controls,  internal  audit practices,  and actions  taken  to correct  deficiencies  as identified.
Because  of  its  inherent  limitations,  internal  control  over  financial  reporting  may  not  prevent  or  detect  misstatements.  Projections  of  any  evaluation  of  internal  control  over  financial
reporting effectiveness to future periods are subject to risks. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance
with policies or procedures.

Management assessed the effectiveness of our internal control over financial reporting as of December 31, 2015, the end of our fiscal year, and has reviewed the results of this
assessment with the Audit Committee of our Board of Directors. Management based its assessment on criteria established in Internal Control-Integrated Framework (2013) issued by the
Committee of Sponsoring Organizations of the Treadway Commission. Management’s assessment included evaluation of such elements as the design and operating effectiveness of key
financial reporting controls, process documentation, accounting policies, and our overall control environment. Based on the assessment, management has concluded our internal control
over financial reporting was effective as of the end of the fiscal year 2015 to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial
statements for external reporting purposes in accordance with GAAP.

The scope of management’s assessment of the effectiveness of its internal control over financial reporting as of December 31, 2015 included our consolidated operations except
for the operations of Tower and Lineage, which we acquired in March 2015. Tower and Lineage represented 2% and 14% of our consolidated assets and consolidated revenues as of and
for the year ended December 31, 2015.

The effectiveness of our internal control over financial reporting as of December 31, 2015 has been audited by KPMG LLP, an independent registered public accounting firm, as

stated in their report which is included immediately below.

The Board of Directors and Stockholders
Impax Laboratories, Inc.:

Report of Independent Registered Public Accounting Firm

We  have  audited  Impax  Laboratories,  Inc.’s  internal  control  over  financial  reporting  as  of  December  31,  2015,  based  on  criteria  established  in  Internal Control—Integrated
Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Impax Laboratories, Inc.’s management is responsible for maintaining
effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management 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 conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform
the  audit  to  obtain  reasonable  assurance  about  whether  effective  internal  control  over  financial  reporting  was  maintained  in  all  material  respects.  Our  audit  included  obtaining  an
understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal
control  based  on  the  assessed  risk.  Our  audit  also  included  performing  such  other  procedures  as  we  considered  necessary  in  the  circumstances.  We  believe  that  our  audit  provides  a
reasonable basis for our opinion.

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

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

In  our  opinion,  Impax  Laboratories,  Inc.  maintained,  in  all  material  respects,  effective  internal  control  over  financial  reporting  as  of  December  31,  2015,  based  on  criteria

established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

The  scope  of  management’s  assessment  of  the  effectiveness  of  their  internal  control  over  financial  reporting  as  of  December  31,  2015  included  Impax  Laboratories,  Inc.’s
consolidated operations except for the operations of Tower Holdings, Inc. and Lineage Therapeutics Inc., which Impax Laboratories, Inc. acquired in March 2015. Tower Holdings, Inc.
and  Lineage  Therapeutics  Inc.  represented  2%  and  14%  of  Impax  Laboratories,  Inc.  and  subsidiaries’  consolidated  assets  and  consolidated  revenues  as  of  and  for  the  year  ended
December 31, 2015. Our audit of internal control over financial reporting of Impax Laboratories, Inc. also excluded an evaluation of the internal control over financial reporting of Tower
Holdings, Inc. and Lineage Therapeutics Inc.

We  also  have  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United  States),  the  consolidated  balance  sheets  of  Impax
Laboratories, Inc. and subsidiaries as of December 31, 2015 and 2014, and the related consolidated statements of income, comprehensive income, changes in stockholders’ equity, and
cash  flows  for  each  of  the  years  in  the  three-year  period  ended  December  31,  2015, and  our  report  dated  February  22, 2016,  expressed  an  unqualified  opinion  on  those  consolidated
financial statements.

Impax Laboratories, Inc.

Report of Independent Registered Public Accounting Firm

We have audited the accompanying consolidated balance sheets of Impax Laboratories, Inc. and subsidiaries as of December 31, 2015 and 2014, and the related consolidated
statements of income, comprehensive income, changes in stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2015. In connection with
our  audits  of  the  consolidated  financial  statements,  we  have  also  audited  the  related  financial  statement  schedule.  These  consolidated  financial  statements  and  the  related  financial
statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements and financial statement
schedule based on our audits.

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

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Impax Laboratories, Inc. and subsidiaries as
of December 31, 2015 and 2014, and the results of their operations  and their cash flows for each of the years in the three-year  period ended December 31, 2015, in conformity with
U.S. generally accepted accounting principles. Also in our opinion, the related financial statement schedule, when considered in relation to the basic consolidated financial statements
taken as a whole, presents fairly, in all material respects, the information set forth therein.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Impax Laboratories, Inc.’s internal control over
financial reporting as of December 31, 2015, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of
the  Treadway  Commission  (COSO),  and  our  report  dated  February  22,  2016  expressed  an  unqualified  opinion  on  the  effectiveness  of  the  Company’s  internal  control  over  financial
reporting.

Our report dated February 22, 2016, on the effectiveness of internal control over financial reporting as of December 31, 2015, contains an explanatory paragraph that states that
the  scope  of  management’s  assessment  of  their  effectiveness  of  internal  control  over  financial  reporting  as  of  December  31,  2015  included  Impax  Laboratories,  Inc.’s  consolidated
operations except for the operations of Tower Holdings, Inc. and Lineage Therapeutics Inc., which Impax Laboratories, Inc. acquired in March 2015. Tower Holdings, Inc. and Lineage
Therapeutics Inc. represented 2% and 14% of Impax Laboratories, Inc. and subsidiaries’ consolidated assets and consolidated revenues as of and for the year ended December 31, 2015.
Our audit of internal control over financial reporting of Impax Laboratories, Inc. also excluded an evaluation of the internal control over financial reporting of Tower Holdings, Inc. and
Lineage Therapeutics Inc.

1. DESCRIPTION OF BUSINESS

IMPAX LABORATORIES, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Impax Laboratories, Inc. (“Impax” or the “Company”) is a specialty pharmaceutical company that focuses on developing, manufacturing, marketing and distributing generic and
branded pharmaceutical products. The Company has two reportable segments, referred to as “Impax Generics” and “Impax Specialty Pharma.” The Impax Generics division focuses on a
broad range of therapeutic areas, including products having technically challenging drug-delivery mechanisms or unique product formulations. In addition to developing solid oral dosage
products, the Impax Generic division’s portfolio includes alternative dosage form products, primarily through alliance and collaboration agreements with third parties. The Company’s
Impax Specialty  Pharma division is focused on the development  and promotion,  through the  Company’s specialty  sales  force, of proprietary  branded pharmaceutical  products  for the
treatment  of  central  nervous  system  (“CNS”)  disorders  and  other  select  specialty  segments.  As  described  in  detail  below,  in  March  2015,  the  Company  renamed  its  operating  and
reporting structure into its current structure; prior to such time, the Impax Generics division was referred to as “Global Pharmaceuticals” and the Impax Specialty Pharma division was
referred to as “Impax Pharmaceuticals.”

Tower Acquisition

On  March  9,  2015,  Impax  completed  its  acquisition  of  Tower  Holdings,  Inc.  (“Tower”),  including  its  operating  subsidiaries  CorePharma  LLC  (“CorePharma”)  and  Amedra
Pharmaceuticals LLC (“Amedra Pharmaceuticals”), and Lineage Therapeutics Inc. (“Lineage”) for a purchase price of approximately $691.3 million, net of approximately $41.5 million
of  cash  acquired  and  including  the  repayment  of  indebtedness  of  Tower  and  Lineage  (the  “Tower  acquisition”).  The  privately-held  companies  specialized  in  the  development,
manufacture and commercialization of complex generic and branded pharmaceutical products. For additional information on the acquisition and the related financing of the acquisition,
refer to “Note 2. Business Acquisition” and “Note 14. Debt.”

In connection with the Tower acquisition, the Company recorded an accrual for severance and related termination costs of $2.4 million during 2015 related to the elimination of
approximately 10 positions at the acquired companies. As of December 31, 2015, $2.1 million has been paid and the Company currently expects the remainder of this balance to be paid
by the first half of 2016.

Revised Operating and Reporting Structure

In  connection  with  the  closing  of  the  Tower  acquisition,  Impax  renamed  the  operating  and  reporting  structure  of  its  two  divisions  into  Impax  Generics  and  Impax  Specialty
Pharma. Impax Generics includes the Company’s legacy Global Pharmaceuticals business as well as the acquired CorePharma and Lineage businesses. Impax Specialty Pharma includes
the legacy Impax Pharmaceuticals business as well as the acquired Amedra Pharmaceuticals business.

Impax Generics develops, manufactures, sells, and distributes generic pharmaceutical products primarily through the following four sales channels: the “Impax Generics” sales
channel, for generic pharmaceutical prescription products the Company sells directly to wholesalers, large retail drug chains, and others; the “Private Label” sales channel, for generic
pharmaceutical over-the-counter (“OTC”) and prescription products the Company sells to unrelated third-party customers who, in turn, sell the product to third parties under their own
label; the “Rx Partner” sales channel, for generic prescription products sold through unrelated third-party pharmaceutical entities under their own label pursuant to alliance agreements;
and the “OTC Partner” sales channel, for generic pharmaceutical OTC products sold through unrelated third-party pharmaceutical entities under their own labels pursuant to alliance and
supply agreements. Revenues from the “Impax Generics” sales channel and the “Private Label” sales channel are reported under the caption “Impax Generics sales, net” in “Note 24.
Supplementary Financial Information.” The Company also generates revenue in Impax Generics from research and development services provided under a joint development agreement
with  another  unrelated  third-party  pharmaceutical  company,  and  reports  such  revenue  under  the  caption  “Other  Revenues”  in  “Note  24.  Supplementary  Financial  Information.”  The
Company provides these services through the research and development group in Impax Generics. Revenues from the “OTC Partner” sales channel are also reported under the caption
“Other Revenues” in “Note 24. Supplementary Financial Information.”

Impax Specialty Pharma is engaged in the development, sale and distribution of proprietary brand pharmaceutical products that the Company believes represent improvements to
already-approved  pharmaceutical  products  addressing  CNS  disorders  and  other  select  specialty  segments.  Impax  Specialty  Pharma  currently  has  one  internally  developed  branded
pharmaceutical product, Rytary® (IPX066), an extended release oral capsule formulation of carbidopa-levodopa for the treatment of Parkinson’s disease, post-encephalitic parkinsonism,
and parkinsonism that may follow carbon monoxide intoxication and/or manganese intoxication, which was approved by the FDA on January 7, 2015 and which the Company began
marketing in the United States (“U.S.”) in April 2015. The Company received marketing authorization from the European Commission for NUMIENT™ (the brand name of IPX066
outside of the United States) during the fourth quarter of fiscal year 2015. Impax Specialty Pharma is also engaged in the sale and distribution of four other branded products; the more
significant include Zomig® (zolmitriptan) products, indicated for the treatment of migraine headaches, under the terms of a Distribution, License, Development and Supply Agreement
(“AZ Agreement”) with AstraZeneca UK Limited (“AstraZeneca”) in the United States and in certain U.S. territories, and Albenza®, indicated for the treatment of tapeworm infections.
Revenues  from  Impax-labeled  branded  products  are  reported  under  the  caption  “Impax  Specialty  Pharma  sales,  net”  in  “Note  24.  Supplementary  Financial  Information.”  Finally,  the
Company generates revenue in Impax Specialty Pharma from research and development services provided under a development and license agreement with another unrelated third-party
pharmaceutical company, and reports such revenue under the caption “Other Revenues” in “Note 24. Supplementary Financial Information.” Impax Specialty Pharma also has a number
of product candidates that are in varying stages of development. See “Note 23. Segment Information,” for financial information about our segments for the years ended December 31,
2015, 2014 and 2013.

The  Company  owns  and/or  leases  facilities  in  California,  Pennsylvania,  New  Jersey  and  Taiwan,  Republic  of  China  (“R.O.C.”).  In  California,  the  Company  utilizes  a
combination  of  owned  and  leased  facilities  mainly  located  in  Hayward.  The  Company’s  primary  properties  in  California  consist  of  a  leased  office  building  used  as  the  Company’s
corporate headquarters, in addition to five properties it owns, including a research and development center facility and a manufacturing facility. Additionally, the Company leases two
facilities in Hayward, utilized for additional research and development, equipment storage and quality assurance support. In Pennsylvania, the Company leases facilities in New Britain
and  Montgomeryville  used  for  sales  and  marketing,  finance,  and  administrative  personnel.  In  addition,  the  Company  owns  a  packaging  plant  in  Philadelphia,  PA  that  was  closed  in
conjunction with the restructuring of packaging and distribution operations announced in June 2015 and, discussed below. In New Jersey, the Company leases manufacturing, packaging,
research and development and warehousing facilities in Middlesex, New Jersey and office space in Bridgewater, New Jersey. Outside the United States, in Taiwan, R.O.C., the Company
owns a manufacturing facility.

CEO Transition

On June 25, 2013, the Company announced that Dr. Larry Hsu planned to retire as President and Chief Executive Officer of Impax and on April 21, 2014, Dr. Hsu retired from
those positions at Impax. Dr. Hsu subsequently resigned as a member of the Company’s Board of Directors, effective July 2, 2015. In connection with his retirement as the Company’s
President and Chief Executive Officer, Dr. Hsu entered into a Separation Agreement with the Company dated June 24, 2013 (the “Separation Agreement”). Pursuant to the Separation
Agreement, the Company provided Dr. Hsu with certain termination benefits and payments. The Company recorded $5.0 million in costs associated with Dr. Hsu’s retirement in the three
month period ended June 30, 2013, comprised of $2.7 million of separation pay and benefits and $2.3 million of accelerated expense related to Dr. Hsu’s outstanding stock options and
restricted stock. Refer to “Note 17. Share-based Compensation” for more information on the acceleration of Dr. Hsu’s equity awards.

Management Changes

During  the  three  month  period  ended  March  31,  2014,  the  Company  announced  a  management  change.  The  Company’s  then  Senior  Vice  President,  Global  Operations
announced plans to retire and a Senior Vice President, Technical Operations was appointed. The Company’s then Senior Vice President, Global Operations subsequently retired from the
Company in July 2014. In conjunction with the transition, the Company recorded $0.9 million in separation charges and accelerated share-based compensation expense in the six month
period ended June 30, 2014.

Workforce Reductions

On  June  4,  2013,  the  Company  committed  to  a  reduction  in  the  Company’s  workforce,  eliminating  approximately  110  positions,  with  the  majority  of  these  positions  at  the
Company’s  Hayward,  California  manufacturing  facility.  The  reduction  in  workforce  is  part  of  the  Company’s  efforts  to  streamline  its  operations  in  response  to  the  need  to  reduce
expenses and adapt to changing market conditions. The Company recorded an accrual for severance and related termination costs of $3.0 million in the three month period ended June 30,
2013 as a result of this workforce reduction. As of December 31, 2013, all accrued severance and related termination costs had been paid.

On October 30, 2014, the Company committed to a reduction in the Company’s workforce, eliminating approximately 41 positions, including 35 positions in the Company’s
research and development (“R&D”) organization. The reduction in workforce is part of the Company’s reorganization of its R&D organizations by consolidating the product development
and analytical functions of the generic and brand R&D organizations. The workforce reduction resulted in charges of $2.1 million for severance and related termination costs, which were
recorded during the quarter ended December 31, 2014. As of December 31, 2015, all accrued severance and related termination costs had been paid.

Restructuring of Packaging and Distribution Operations

On June 30, 2015, the Company committed to a restructuring of its packaging and distribution operations. As a result of this restructuring, the Company closed its Philadelphia
packaging site and all Company-wide distribution operations were outsourced to United Parcel Services (UPS). In conjunction with the restructuring, approximately 93 positions have
been eliminated. The Company recorded an accrual for severance and related termination costs of $2.6 million in the three month period ended June 30, 2015. As of December 31, 2015,
$0.9 million has been paid and the Company currently expects the remainder of this balance to be paid by December 31, 2016.

Restructuring of Technical Operations and R&D

In November 2015, management assessed the headcount in the technical operations and research and development groups, primarily as a result of the resolution of the warning
letter  at  the  Hayward  facility.  The  Company  eliminated  27  positions  and  recorded  an  accrual  for  severance  and  related  termination  costs  of  $2.5  million  during  the  quarter  ended
December 31, 2015. As of December 31, 2015, $0.9 million has been paid and the Company currently expects the remainder of this balance to be paid by early 2017.

2. BUSINESS ACQUISITION

On March  9, 2015, the  Company  completed  the  Tower  acquisition,  which  included  the  acquisition  of  all  of the  outstanding  shares  of  common  stock  of  Tower  and  Lineage,
pursuant to the Stock Purchase Agreement dated as of October 8, 2014, by and among the Company, Tower, Lineage, Roundtable Healthcare Partners II, L.P., Roundtable Healthcare
Investors  II,  L.P.,  and  the  other  parties  thereto,  including  holders  of  certain  options  and  warrants  to  acquire  the  common  stock  of  Tower  or  Lineage.  In  connection  with  the  Tower
acquisition, the options and warrants of Tower and Lineage that were outstanding at the time of the acquisition were cancelled. The total consideration paid for Tower and Lineage was
approximately  $691.3  million,  net  of  approximately  $41.5  million  of  cash  acquired  and  including  the  repayment  of  indebtedness  of  Tower  and  Lineage.  The  Company  incurred
acquisition-related costs of $10.9 million, of which $6.7 million are included in selling, general and administrative expenses in the Company’s consolidated statement of income for the
year ended December 31, 2015.

The  Tower  acquisition  allows  the  Company  to  expand  its  commercialized  generic  and  branded  product  portfolios.  The  Company  also  leverages  its  sales  and  marketing

organization to promote the marketed products acquired.

Consideration

The Company has accounted  for the Tower acquisition  as a business  combination  under  the acquisition  method  of accounting.  The Company has preliminarily  allocated  the
purchase price for the transaction based upon the estimated fair value of net assets acquired and liabilities assumed at the date of acquisition. Accordingly, the preliminary purchase price
allocation described below is subject to change, as the Company expects to finalize the allocation of the purchase price upon the resolution of certain tax accounts that are based on the
best estimates of management. The completion and filing of federal and state tax returns for the various purchased entities of Tower may result in adjustments to the carrying value of
assets and liabilities. Any adjustments to the preliminary fair values will be made as soon as practicable but no later than one year from the March 9, 2015 acquisition date.

(1) The accounts receivable acquired in the transaction had a fair value of approximately $57.0 million, including an allowance for doubtful accounts of approximately $9.0

million, which represents the Company’s best estimate on March 9, 2015 (the closing date of the transaction) of the contractual cash flows not expected to be collected by
the acquired companies.

The  estimated  fair  value  of  the  in-process  research  and  development  and  identifiable  intangible  assets  was  determined  using  the  “income  approach,”  which  is  a  valuation
technique that provides an estimate of the fair value of an asset based on market participant expectations of the cash flows an asset would generate over its remaining useful life. Some of
the  more  significant  assumptions  inherent  in  the  development  of  those  asset  valuations  include  the  estimated  net  cash  flows  for  each  year  for  each  asset  or  product  (including  net
revenues, cost of sales, research and development costs, selling and marketing costs and working capital/asset contributory asset charges), the appropriate discount rate to select in order
to measure the risk inherent in each future cash flow stream, the assessment of each asset’s life cycle, the potential regulatory and commercial success risks, competitive trends impacting
the asset and each cash flow stream as well as other factors. The discount rates used to arrive at the present value at the acquisition date of currently marketed products was 15%. For in-
process  research  and  development,  the  discount  rate  used  was  16%  to  reflect  the  internal  rate  of  return  and  incremental  commercial  uncertainty  in  the  cash  flow  projections.  No
assurances  can  be  given  that  the  underlying  assumptions  used  to  prepare  the  discounted  cash  flow  analysis  will  not  change.  For  these  and  other  reasons,  actual  results  may  vary
significantly from estimated results.

Goodwill

The Company recorded approximately $182.6 million of goodwill in connection with the Tower acquisition, some of which will not be tax-deductible. Approximately $60.2
million of this goodwill was assigned to the Impax Specialty Pharma segment and approximately $122.4 million was assigned to the Impax Generics segment. Factors that contributed to
the Company’s preliminary recognition of goodwill include the Company’s intent to expand its generic and branded pharmaceutical product portfolios and to acquire certain benefits from
the Tower and Lineage product pipelines in addition to the anticipated synergies that the Company expects to generate from the acquisition.

Unaudited Pro Forma Results of Operations

The  unaudited  pro  forma  combined  results  of  operations  for  the  years  ended  December  31,  2015  and  2014  (assuming  the  closing  of  the  acquisition  of  Tower  and  Lineage

occurred on January 1, 2014) are as follows:

The pro forma results have been prepared for comparative purposes only and are not necessarily indicative of the actual results of operations had the closing of the Transaction

taken place on January 1, 2014. Furthermore, the pro forma results do not purport to project the future results of operations of the Company.

The unaudited pro forma information reflects primarily the following adjustments:

Adjustments to amortization expense related to identifiable intangible assets acquired. Net income for the year ended December 31, 2015 reflects the lack of
amortization expense for an acquired intangible asset with a short remaining estimated useful life, which causes the asset to be fully amortized by the end of 2014 under
the pro forma assumption that the acquisition took place January 1, 2014;

Adjustments to depreciation expense related to property, plant and equipment acquired;

Adjustments to interest expense to reflect the long-term debt held by Tower and Lineage paid out and eliminated at the closing and the Barclays Senior Secured Credit
Facilities (described in detail in “Note 14. Debt” below);

Adjustments to cost of revenues related to the fair value adjustments in inventory sold including elimination of approximately $6 million for the year ended December
31, 2015 and additional costs of approximately $6 million for the year ended December 31, 2014;

Adjustments to selling, general and administrative expense related to severance and retention costs of approximately $3 million incurred as part of the Transaction.
 These costs were eliminated in the pro forma results for the year ended December 31, 2015 and included in the pro forma results for the year ended December 31, 2014;

Adjustments to selling, general and administrative expense related to transaction costs directly attributable to the Tower acquisition include the elimination of $12
million of charges in the year ended December 31, 2015 which have been included in the year ended December 31, 2014; and

Adjustments to reflect the elimination of approximately $2.3 million in commitment fees related to the $435 million term loan with Barclays that were incurred during
the year ended December 31, 2015 and were included in the pro forma results for the year ended December 31, 2014.

All of the above adjustments were adjusted for the applicable tax impact.

Securities & Exchange Commission (“SEC”) requires the use of estimates and assumptions, based on complex judgments considered reasonable, and affect the reported amounts of assets
and liabilities and disclosure of contingent assets and contingent liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during
the reporting period. The most significant judgments are employed in estimates used in determining values of tangible and intangible assets, derivatives, legal contingencies, tax assets
and tax liabilities, fair value of share-based compensation related to equity incentive awards issued to employees and directors, and estimates used in applying the Company’s revenue
recognition policy, including those related to accrued chargebacks, rebates, product returns, Medicare, Medicaid, and other government rebate programs, shelf-stock adjustments, and the
timing and amount of deferred and recognized revenue and deferred and amortized product manufacturing costs related to alliance and collaboration agreements. Actual results may differ
from estimated results.

Reclassifications

Certain prior year amounts have been reclassified to conform to the presentation for the year ended December 31, 2015.

4. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Cash and Cash Equivalents

The Company considers all short-term investments with maturity of three months or less at the date of purchase to be cash equivalents. Cash and cash equivalents are stated at
cost, which, for cash equivalents, approximates fair value due to their short-term maturity. The Company is potentially subject to financial instrument concentration of credit risk through
its cash and cash equivalents. The Company maintains cash and cash equivalents with several major financial institutions. Such amounts frequently exceed Federal Deposit Insurance
Corporation (“FDIC”) limits.

Short-Term Investments

Short-term investments represented investments in fixed rate financial instruments with maturities of greater than three months but less than 12 months at the time of purchase.
The Company’s short-term investments were held in U.S. Treasury securities, corporate bonds, and high grade commercial paper, which are not insured by the FDIC. They were stated at
amortized cost, which approximated fair value due to their short-term maturity, generally based upon observable market values of similar securities.

Allowance for Doubtful Accounts

The Company maintains allowances for doubtful accounts for estimated losses resulting from amounts deemed to be uncollectible from its customers; these allowances are for

specific amounts on certain accounts based on facts and circumstances determined on a case-by-case basis.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk are cash, cash equivalents, and accounts receivable. The Company limits its credit risk
associated with cash and cash equivalents by placing its investments with high quality money market funds, corporate debt, and short-term commercial paper and in securities backed by
the U.S. Government. The Company limits its credit risk with respect to accounts receivable by performing credit evaluations when deemed necessary. The Company does not require
collateral to secure amounts owed to it by its customers.

During the years ended December 31, 2015, 2014 and 2013, the Company’s top ten products accounted for 75%, 62% and 68%, respectively, of total Impax product sales, net.

Refer to “Note 24. Supplemental Financial Information” for more information.

In July 2015, the Company received an unsolicited offer from Turing Pharmaceuticals AG (“Turing”) to purchase the U.S. rights to Daraprim®, one of the marketed products
acquired in the Tower acquisition, as well as the active pharmaceutical ingredient for the product and the finished goods inventory on hand. Pursuant to the terms of the Asset Purchase
Agreement between the Company and Turing dated August 7, 2015 (the “Turing APA”), the Company also granted a limited license to sell the existing Daraprim® product under the
Company’s labeler code with the Company’s trade dress. The sale closed on August 7, 2015.

In  accordance  with  the  terms  of  the  Turing  APA,  the  Company  received  and  is  initially  responsible  for  processing  and  paying  (subject  to  reimbursement  by  Turing),  all
chargebacks  and  rebates  resulting  from  utilization  by  Medicaid,  Medicare  and  other  federal,  state  and  local  governmental  programs,  health  plans  and  other  health  care  providers  for
product  sold  under  the  Company’s  labeler  code.    Under  the  terms  of  the  Turing  APA,  Turing  is  responsible  for  liabilities  related  to  chargebacks  and  rebates  that  arise  as  a  result  of
Turing’s marketing or selling related activities.

During the fourth quarter of 2015, the Company began receiving invoices for chargebacks from wholesalers and rebates from various state Medicaid agencies for Daraprim®
purchases made by governmental agencies during the third quarter of 2015.  As a result, the Company recorded a $40.6 million receivable representing an estimate for the third and fourth
quarter  2015  reimbursement  amounts  owed  by  Turing  to  the  Company.    In  addition,  the  Company  recorded  an  accrued  liability  for  the  corresponding  offsetting  amount  owed  to
wholesalers, Medicaid and other governmental agencies. The Company and Turing are currently in the process of finalizing the reimbursement amount owed by Turing to the Company
for such chargebacks and rebates.   If Turing for any reason does not, or is unable to, make such reimbursement payments to the Company, it could result in a material charge to the
Company.

Inventory

Inventory is stated at the lower of cost or market. Cost is determined using a standard cost method, and the cost flow assumption is first in, first out (“FIFO”) flow of goods.
Standard costs are revised annually, and significant variances between actual costs and standard costs are apportioned to inventory and cost of goods sold based upon inventory turnover.
Costs  include  materials,  labor,  quality  control,  and  production  overhead.  Inventory  is  adjusted  for  short-dated,  unmarketable  inventory  equal  to  the  difference  between  the  cost  of
inventory  and  the  estimated  value  based  upon  assumptions  about  future  demand  and  market  conditions.  If  actual  market  conditions  are  less  favorable  than  those  projected  by  the
Company, additional inventory write-downs may be required. Consistent with industry practice, the Company may build pre-launch inventories of certain products which are pending
required  approval  from  the  FDA  and/or  resolution  of  patent  infringement  litigation,  when,  in  the  Company’s  assessment,  such  action  is  appropriate  to  prepare  for  the  anticipated
commercial  launch  and  FDA approval  is  expected  in  the  near  term  and/or  the  related  litigation  will  be  resolved  in  the  Company’s  favor.  The  Company  accounts  for  all  costs  of  idle
facilities, excess freight and handling costs, and wasted materials (spoilage) as a current period charge in accordance with GAAP.

Property, Plant and Equipment

Property, plant and equipment are recorded at cost. Maintenance and repairs are charged to expense as incurred and costs of improvements and renewals are capitalized. Costs
incurred in connection with the construction or major renovation of facilities, including interest directly related to such projects, are capitalized as construction in progress. Depreciation
is recognized using the straight-line method based on the estimated useful lives of the related assets, which are generally 40 years for buildings, 10 to 15 years for building improvements,
eight to 10 years for equipment, and four to 10 years for office furniture and equipment. Land and construction-in-progress are not depreciated.

Intangible Assets

The Company’s intangible assets include both indefinite lived and finite lived assets. Indefinite lived intangible assets are not amortized. In-process research and development
assets acquired in a business combination are considered indefinite lived until the completion or abandonment of the associated research and development efforts. Finite lived intangible
assets are amortized over the estimated useful life based on the pattern in which the economic benefits of the intangible asset are consumed or otherwise used up. If that pattern cannot be
reliably determined, the straight-line amortization method is used. All of the Company’s intangible assets are tested for impairment at least annually during the fourth quarter of the fiscal
year, or more often if indicators of impairment are present. Impairment testing requires management to estimate the future undiscounted cash flows of the finite lived intangible assets
using assumptions believed to be reasonable, but which are unpredictable and inherently uncertain. Actual future cash flows may differ from the estimates used in the impairment testing.
The Company recognizes an impairment loss when and to the extent that the estimated fair value of an intangible asset is less than its carrying value.

Goodwill

In accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification™ (“ASC”) Topic 350, "Goodwill and Other Intangibles", rather than
recording periodic amortization, goodwill is subject to an annual assessment for impairment by applying a fair value based test. Under FASB ASC Topic 350, if the fair value of the
reporting unit exceeds the reporting unit’s carrying value, including goodwill, then goodwill is considered not impaired, making further analysis not required. The Company considers the
Impax  Generics  division  and  the  Impax  Specialty  Pharma  division  operating  segments  to  each  be  a  reporting  unit.  The  Company  attributes  $60.2  million  of  goodwill  to  the  Impax
Specialty Pharma division and $150.0 million of goodwill to the Impax Generics division.

The Company concluded the carrying value of goodwill was not impaired as of December 31, 2015 and 2014 as the fair value of the Impax Specialty Pharma division and the
Impax  Generics  division  exceeded  their  carrying  value  at  each  date.  The  Company  performs  its  annual  goodwill  impairment  test  in  the  fourth  quarter  of  each  year.  The  Company
estimated the fair value of the Impax Specialty Pharma division and the Impax Generics division using a discounted cash flow model for both the reporting unit and the enterprise. In
addition, on a quarterly basis, the Company performs a review of its business operations  to determine  whether events or changes in circumstances  have occurred which could have a
material  adverse  effect  on  the  estimated  fair  value  of  each  reporting  unit,  and  thus  indicate  a  potential  impairment  of  the  goodwill  carrying  value.  If  such  events  or  changes  in
circumstances  were  deemed  to  have  occurred,  the  Company  would  perform  an  interim  impairment  analysis,  which  may  include  the  preparation  of  a  discounted  cash  flow  model,  or
consultation with one or more valuation specialists, to determine the impact, if any, on the Company’s assessment of the reporting unit’s fair value. The Company has not to date deemed
there to have been any significant adverse changes in the legal, regulatory, or general economic environment in which the Company conducts its business operations.

Derivatives

The  Company  generally  does  not  use  derivative  instruments  or  engage  in  hedging  activities  in  its  ordinary  course  of  business.  Prior  to  June  30,  2015,  the  Company  had  no
derivative assets or liabilities and did not engage in any hedging activities. As a result of the Company’s June 30, 2015 issuance of the convertible senior notes described in “Note 14.
Debt”, the  conversion  option of  the notes temporarily  met  the criteria  for an embedded  derivative  liability  which  required  bifurcation  and  separate  accounting.  Concurrently  with the
issuance of the notes, the Company entered into a series of convertible note hedge and warrant transactions  which in combination are designed to reduce the potential dilution to the
Company’s stockholders and/or offset the cash payments the Company is required to make in excess of the principal amount upon conversion of the notes. See “Note 8. Derivatives” and
“Note 15. Stockholders’ Equity” for additional information regarding the note hedge transactions and warrant transactions. While the warrants sold were classified as equity and recorded
in additional paid-in capital, the call options purchased were temporarily classified as a bond hedge derivative asset on the Company’s consolidated balance sheet. The Company engaged
a third-party valuation firm with expertise in valuing financial instruments to determine the fair value of the bond hedge derivative asset and conversion option derivative liability at each
reporting period. The Company’s interim consolidated balance sheets reflected the fair value of the derivative asset and liability as of the reporting date, and changes in the fair value
were reflected in current period earnings, as appropriate. As result of the amendment to the Company’s Restated Certificate of Incorporation to increase the number of authorized shares
of the Company's common stock discussed in “Note 15. Stockholders’ Equity,” both the derivative asset and liability were reclassified to additional paid-in capital. The Company had no
derivative assets or liabilities and did not engage in any hedging activities as of December 31, 2015.

Contingencies

In the normal course of business, the Company is subject to loss contingencies, such as legal proceedings and claims arising out of its business, covering a wide range of matters,
including, among others, patent litigation, stockholder lawsuits, and product and clinical trial liability. In accordance with FASB ASC Topic 450, "Contingencies", the Company records
accruals for such loss contingencies when it is probable a liability will have been incurred and the amount of loss can be reasonably estimated. The Company, in accordance with FASB
ASC Topic 450, does not recognize gain contingencies until realized. The Company records an accrual for legal costs in the period incurred. A discussion of contingencies is included in
“Note 21. Commitments and Contingencies,” and “Note 22. Legal and Regulatory Matters” footnotes below.

Deferred Financing Costs

The Company capitalizes direct costs incurred to obtain debt financing and amortizes these costs to interest expense using the effective interest method over the term of the debt.
These costs are recorded as a debt discount and the unamortized costs are netted against the related debt on the Company’s consolidated balance sheet. For line-of-credit arrangements
with  no  outstanding  borrowing,  the  costs  incurred  to  obtain  the  credit  facility  are  amortized  to  interest  expense  using  the  straight-line  method  over  the  term  of  the  line-of-credit
arrangement. The unamortized balance is included in other assets on the Company’s consolidated balance sheet..

Revenue Recognition

The Company recognizes revenue when the earnings process is complete, which under SEC Staff Accounting Bulletin No. 104, Topic No. 13, “Revenue Recognition” (“SAB
104”), is when revenue is realized or realizable and earned, there is persuasive evidence a revenue arrangement exists, delivery of goods or services has occurred, the sales price is fixed
or determinable, and collectability is reasonably assured.

The  Company  accounts  for  material  revenue  arrangements  which  contain  multiple  deliverables  in  accordance  with  FASB  ASC  Topic  605-25,  revenue  recognition  for
arrangements  with  multiple  elements,  which  addresses  the  determination  of  whether  an  arrangement  involving  multiple  deliverables  contains  more  than  one  unit  of  accounting.  A
delivered item within an arrangement is considered a separate unit of accounting only if both of the following criteria are met:

●
●

the delivered item has value to the customer on a stand-alone basis; and
if the arrangement includes a general right of return relative to the delivered item, delivery or performance of the undelivered item is considered probable and substantially
in the control of the vendor.

Under FASB ASC Topic 605-25, if both of the criteria above are not met, then separate accounting for the individual deliverables is not appropriate. Revenue recognition for
arrangements  with  multiple  deliverables  constituting  a  single  unit  of  accounting  is  recognized  generally  over  the  greater  of  the  term  of  the  arrangement  or  the  expected  period  of
performance, either on a straight-line basis or on a modified proportional performance method.

The Company accounts for milestones related to research and development activities in accordance with FASB ASC Topic 605-28, milestone method of revenue recognition.
FASB ASC Topic 605-28 allows for the recognition of consideration, which is contingent on the achievement of a substantive milestone, in its entirety in the period the milestone is
achieved.  A  milestone  is  considered  to  be  substantive  if  all  of  the  following  criteria  are  met:  the  milestone  is  commensurate  with  either:  (1)  the  performance  required  to  achieve  the
milestone, or (2) the enhancement of the value of the delivered items resulting from the performance required to achieve the milestone; the milestone relates solely to past performance;
and, the milestone payment is reasonable relative to all of the deliverables and payment terms within the agreement.

Impax Generics revenues, net, and Impax Specialty Pharma revenues, net

The Impax Generics revenues, net and Impax Specialty Pharma revenues, net include revenue recognized related to shipments of generic and branded pharmaceutical products to
the Company’s customers, primarily drug wholesalers and retail chains. Gross sales revenue is recognized at the time title and risk of loss passes to the customer, which is generally when
product is received by the customer. Impax Generics and Impax Specialty Pharma revenue, net may include deductions from the gross sales price related to estimates for chargebacks,
rebates,  distribution  service  fees,  returns,  shelf-stock,  and  other  pricing  adjustments.  The  Company  records  an  estimate  for  these  deductions  in  the  same  period  when  revenue  is
recognized. A summary of each of these deductions is as follows:

F-17

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Chargebacks

The Company has agreements establishing contract prices for certain products with certain indirect customers, such as managed care organizations, hospitals and government
agencies who purchase products from drug wholesalers. The contract prices are lower than the prices the customer would otherwise pay to the wholesaler, and the price difference is
referred to as a chargeback, which generally takes the form of a credit memo issued by the Company to reduce the invoiced gross selling price charged to the wholesaler. An estimated
accrued provision for chargeback deductions is recognized at the time of product shipment. The primary factors considered when estimating the provision for chargebacks are the average
historical  chargeback  credits  given,  the  mix  of  products  shipped,  and  the  amount  of  inventory  on  hand  at  the  major  drug  wholesalers  with  whom  the  Company  does  business.  The
Company also monitors actual chargebacks granted and compares them to the estimated provision for chargebacks to assess the reasonableness of the chargeback reserve at each quarterly
balance sheet date.

Rebates

The Company maintains various rebate programs with its customers in an effort to maintain a competitive position in the marketplace and to promote sales and customer loyalty.
The rebates generally take the form of a credit memo to reduce the invoiced gross selling price charged to a customer for products shipped. An estimated accrued provision for rebate
deductions is recognized at the time of product shipment. The primary factors the Company considers when estimating the provision for rebates are the average historical experience of
aggregate credits issued, the mix of products shipped and the historical relationship of rebates as a percentage of total gross product sales, the contract terms and conditions of the various
rebate  programs  in  effect  at  the  time  of  shipment,  and  the  amount  of  inventory  on  hand  at  the  major  drug  wholesalers  with  whom  the  Company  does  business.  The  Company  also
monitors actual rebates granted and compares them to the estimated provision for rebates to assess the reasonableness of the rebate reserve at each quarterly balance sheet date.

Distribution Service Fees

The Company pays distribution service fees to several of its wholesaler customers related to sales of its Impax Products. The wholesalers are generally obligated to provide the
Company with periodic outbound sales information as well as inventory levels of the Company’s Impax Products held in their warehouses. Additionally, the wholesalers have agreed to
manage the variability of their purchases and inventory levels within specified days on hand limits. An accrued provision for distribution service fees is recognized at the time products
are shipped to wholesalers.

Returns

The Company allows its customers to return product if approved by authorized personnel in writing or by telephone with the lot number and expiration date accompanying any
request and if such products are returned within six months prior to or until twelve months following, the products’ expiration date. The Company estimates and recognizes an accrued
provision  for  product  returns  as  a  percentage  of  gross  sales  based  upon  historical  experience.  The  product  return  reserve  is  estimated  using  a  historical  lag  period,  which  is  the  time
between when the product is sold and when it is ultimately returned, and estimated return rates which may be adjusted based on various assumptions including changes to internal policies
and  procedures,  changes  in  business  practices,  and  commercial  terms  with  customers,  competitive  position  of  each  product,  amount  of  inventory  in  the  wholesaler  supply  chain,  the
introduction  of  new  products,  and  changes  in  market  sales  information.  The  Company  also  considers  other  factors,  including  significant  market  changes  which  may  impact  future
expected  returns,  and  actual  product  returns.  The  Company  monitors  actual  returns  on  a  quarterly  basis  and  may  record  specific  provisions  for  returns  it  believes  are  not  covered  by
historical percentages.

F-18

 
 
 
 
 
 
 
 
 
 
 
Shelf-Stock Adjustments

Based upon competitive market conditions, the Company may reduce the selling price of certain Impax Generics division products. The Company may issue a credit against the
sales  amount  to  a  customer  based  upon  their  remaining  inventory  of  the  product  in  question,  provided  the  customer  agrees  to  continue  to  make  future  purchases  of  product  from  the
Company.  This  type  of  customer  credit  is  referred  to  as  a  shelf-stock  adjustment,  which  is  the  difference  between  the  sales  price  and  the  revised  lower  sales  price,  multiplied  by  an
estimate of the number of product units on hand at a given date. Decreases in selling prices are discretionary decisions made by the Company in response to market conditions, including
estimated launch dates of competing products and declines in market price. The Company records an estimate for shelf-stock adjustments in the period it agrees to grant such a credit
memo to a customer.

Medicaid and Other Government Pricing Programs

As required by law, the Company provides a rebate on drugs dispensed under the Medicaid program, Medicare Part D, TRICARE, and other U.S. government pricing programs.
The Company determines its estimated government rebate accrual primarily based on historical experience of claims submitted by the various states and other jurisdictions and any new
information regarding changes in the various programs which may impact the Company’s estimate of government rebates. In determining the appropriate accrual amount, the Company
considers historical payment rates and processing lag for outstanding claims and payments. The Company records estimates for government rebates as a deduction from gross sales, with
a corresponding adjustment to accrued liabilities.

Cash Discounts

The Company offers cash discounts to its customers, generally 2% of the gross selling price, as an incentive for paying within invoice terms, which generally range from 30 to

90 days. An estimate of cash discounts is recorded in the same period when revenue is recognized.

Rx Partner and OTC Partner:

The  Rx  Partner  and  OTC  Partner  contracts  include  revenue  recognized  under  alliance  and  collaboration  agreements  between  the  Company  and  unrelated  third-party
pharmaceutical  companies.  The  Company  has  entered  into  these  alliance  agreements  to  develop  marketing  and/or  distribution  relationships  with  its  partners  to  fully  leverage  its
technology platform.

The  Rx  Partners  and  OTC  Partners  alliance  agreements  obligate  the  Company  to  deliver  multiple  goods  and/or  services  over  extended  periods.  Such  deliverables  include
manufactured pharmaceutical products, exclusive and semi-exclusive marketing rights, distribution licenses, and research and development services. In exchange for these deliverables
the Company receives payments from its agreement partners for product shipments and research and development services, and may also receive other payments including royalty, profit
sharing, upfront, and periodic milestone payments. Revenue received from the alliance agreement partners for product shipments under these agreements is not subject to deductions for
chargebacks, rebates, product returns, and other pricing adjustments. Royalty and profit sharing amounts the Company receives under these agreements are calculated by the respective
agreement partner, with such royalty and profit share amounts generally based upon estimates of net product sales or gross profit which include estimates of deductions for chargebacks,
rebates, product returns, and other adjustments the alliance agreement partners may negotiate with their respective customers. The Company records the agreement partner's adjustments
to such estimated amounts in the period the agreement partner reports the amounts to the Company.

The  Company  applies  the  updated  guidance  of  ASC 605-25  “Multiple  Element  Arrangements”  to  the  Strategic  Alliance  Agreement,  as  amended  with  Teva  Pharmaceuticals
Curacao N.V., a subsidiary of Teva Pharmaceutical Industries Limited (“Teva Agreement”). The Company looks to the underlying delivery of goods and/or services which give rise to the
payment of consideration under the Teva Agreement to determine the appropriate revenue recognition. The Company initially defers consideration received as a result of research and
development-related activities performed under the Teva Agreement. The Company recognizes deferred revenue on a straight-line basis over the expected period of performance for such
services. Consideration received as a result of the manufacture and delivery of products under the Teva Agreement is recognized at the time title and risk of loss passes to the customer
which is generally when product is received by Teva. The Company recognizes profit share revenue in the period earned.

F-19

 
 
 
 
 
 
 
 
 
 
 
 
 
OTC Partner  revenue  is related  to agreements  with Pfizer,  Inc.,  formerly  Wyeth  LLC (“Pfizer”)  and L. Perrigo  Company (“Perrigo”)  with respect  to the supply of over-the-
counter pharmaceutical products. The OTC Partner sales channel is no longer a core area of the business, and the over-the-counter pharmaceutical products the Company sells through
this sales channel are older products which are only sold to Pfizer and Perrigo. The Company is currently only required to manufacture  the over-the-counter  pharmaceutical  products
under its agreements with Pfizer and Perrigo. The Company recognizes profit share revenue in the period earned.

Research Partner:

The Research Partner contract includes revenue recognized under development agreements with unrelated third-party pharmaceutical companies. The development agreements
generally obligate the Company to provide research and development services over multiple periods. In exchange for this service, the Company received upfront payments upon signing
of each development agreement and is eligible to receive contingent milestone payments, based upon the achievement of contractually specified events. Additionally, the Company may
also  receive  royalty  payments  from  the  sale,  if  any,  of  a  successfully  developed  and  commercialized  product  under  one  of  these  development  agreements.  The  Company  recognizes
revenue received from the achievement of contingent research and development milestones in the period such payment is earned. Royalty fee income, if any, will be recognized as current
period revenue when earned.

Shipping and Handling Fees and Costs

Shipping  and  handling  fees  related  to  sales  transactions  are  recorded  as  selling  expense.  Shipping  costs  were  $2,304,000,  $2,382,000  and  $1,890,000  for  the  years  ended

December 31, 2015, 2014 and 2013, respectively.

Research and Development Expenses

Research and development activities  are expensed as incurred and consist of self-funded research and development costs and costs associated with work performed by other

participants under collaborative research and development agreements.

Share-Based Compensation

The Company accounts for stock-based  employee  compensation  arrangements  in accordance  with provisions of FASB ASC Topic 718 “Stock Compensation”.  Under FASB
ASC Topic 718, the Company recognizes the grant date fair value of stock-based employee compensation as expense on a straight-line basis over the vesting period of the grant. The
Company uses the Black Scholes option pricing model to determine the grant date fair value of employee stock options; the fair value of restricted stock awards is equal to the closing
price of the Company’s stock on the date such award was granted.

Income Taxes

The Company provides for income taxes using the asset and liability method as required by FASB ASC Topic 740, “Income Taxes”. This approach recognizes the amount of
federal, state, local taxes, and foreign taxes payable or refundable for the current year, as well as deferred tax assets and liabilities for the future tax consequences of events recognized in
the consolidated financial statements and income tax returns. Deferred income tax assets and liabilities are adjusted to recognize the effects of changes in tax laws or enacted tax rates in
the period during which they are signed into law. Under FASB ASC Topic 740, a valuation allowance is required when it is more likely than not all or some portion of the deferred tax
assets will not be realized through generating sufficient future taxable income.

FASB ASC Topic 740, Sub-topic 10 “Tax Positions”, defines the criterion an individual tax position must meet for any part of the benefit of the tax position to be recognized in
financial statements prepared in conformity with generally accepted accounting principles. Under FASB ASC Topic 740, Sub-topic 10, the Company may recognize the tax benefit from
an  uncertain  tax  position  only  if  it  is  more  likely  than  not  the  tax  position  will  be  sustained  on  examination  by  the  taxing  authorities,  based  solely  on  the  technical  merits  of  the  tax
position. The tax benefits recognized in the financial statements from such a tax position should be measured based on the largest benefit having a greater than 50% likelihood of being
realized upon ultimate settlement with the tax authority. Additionally, FASB ASC Topic 740, Sub-topic 10 provides guidance on measurement, de-recognition, classification, interest and
penalties,  accounting  in  interim  periods,  disclosure,  and  transition.  In  accordance  with  the  disclosure  requirements  of  FASB ASC Topic  740,  Sub-topic  10,  the  Company’s  policy  on
income statement classification of interest and penalties related to income tax obligations is to include such items as part of total interest expense and other expense, respectively.

Other Comprehensive Income

The Company follows the provisions of FASB ASC Topic 220, ”Comprehensive Income”, which establishes standards for the reporting and display of comprehensive income
and its components. Comprehensive income is defined to include all changes in equity during a period except those resulting from investments by owners and distributions to owners. The
Company recorded  foreign currency  translation  gains and losses, which are reported  as comprehensive  income. Foreign currency  translation  losses for  the years ended December  31,
2015, 2014 and 2013 were $4,454,000, $7,149,000 and $4,104,000 respectively.

5. RECENT ACCOUNTING PRONOUNCEMENTS

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers” (Topic 606) regarding the accounting for and disclosures of revenue recognition, with
an effective date for annual and interim periods beginning after December 15, 2016. This update provides a single comprehensive model for accounting for revenue from contracts with
customers.  The model requires  that revenue recognized  reflect  the actual  consideration  to which the entity  expects  to be entitled  in exchange  for the goods or services  defined in the
contract, including in situations with multiple performance obligations. In July 2015, the FASB issued ASU 2015-14, “Revenue from Contracts with Customers (Topic 606): Deferral of
the Effective Date”, which deferred the effective date, of the previously issued revenue recognition guidance by one year. The guidance will be effective for annual and interim periods
beginning after December 15, 2017. The Company is currently evaluating the effect that this guidance may have on its consolidated financial statements.

In  April  2015,  the  FASB  issued  ASU  2015-03,  “Interest—Imputation  of  Interest  (Subtopic  835-30):  Simplifying  the  Presentation  of  Debt  Issuance  Costs”,  which  provided
guidance on the presentation requirements for debt issuance costs and debt discount and premium. The update requires that debt issuance costs related to a recognized debt liability be
presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt
issuance  costs  are  not  affected  by  the  updated  guidance.  The  updated  guidance  is  effective  for  annual  and  interim  periods  beginning  after  December  15,  2015  and  early  adoption  is
permitted for financial statements that have not been previously issued. The Company adopted this guidance during 2015, and it had no effect on the Company’s results of operations.

In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): “Simplifying the Measurement of Inventory”, with guidance regarding the accounting for and measurement
of inventory. The update requires that inventory measured using first-in, first-out (FIFO) shall be measured at the lower of cost and net realizable value. When there is evidence that the
net realizable value of inventory is lower than its cost, the difference shall be recognized as a loss in earnings in the period in which it occurs. The guidance will be effective for annual
and interim periods beginning after December 15, 2016. The Company is currently evaluating the effect that this guidance may have on its consolidated financial statements.

In  August  2015,  the  FASB  issued  ASU  2015-15,  “Interest—Imputation  of  Interest  (Subtopic  835-30):  Presentation  and  Subsequent  Measurement  of  Debt  Issuance  Costs
Associated  with Line-of-Credit  Arrangements”,  with  guidance  on the  presentation  and  measurement  of debt  issuance  costs  associated  with line-of-credit  arrangements.  ASU 2015-03
previously issued in April 2015 did not address the presentation or subsequent measurement of debt issuance costs related to line-of-credit arrangements. ASU 2015-15 states that the
SEC would not object to the deferral and presentation of debt issuance costs as an asset and subsequent amortization of debt issuance costs over the term of the line-of-credit arrangement,
whether or not there are any outstanding borrowings on the line-of-credit arrangement. The Company adopted this guidance during 2015, and it had no effect on the Company’s results of
operations.

F-21

 
 
 
 
 
 
 
 
 
 
In September 2015, the FASB issued ASU 2015-16, Business Combinations (Topic 805): “Simplifying the Accounting for Measurement-Period Adjustments”, with guidance
regarding the accounting for and disclosure of measurement-period adjustments that occur in periods after a business combination is consummated. This update requires that the acquirer
recognize measurement-period adjustments in the reporting period in which they are determined and, as such, eliminates the previous requirement to retrospectively account for these
adjustments.  This update also requires  an entity  to present separately  on the face  of the income  statement,  or disclose  in the notes, the amount recorded  in the current-period  income
statement that would have been recorded in previous reporting periods if the adjustments had been recognized as of the acquisition date. The effective date for annual and interim periods
begins after December 15, 2015. The Company is currently evaluating the effect that this guidance may have on its consolidated financial statements.

In November 2015, the FASB issued ASU 2015-17, “Balance  Sheet Classification  of Deferred  Taxes”, which requires  that deferred  tax assets and liabilities  be classified  as
noncurrent  in  a  classified  statement  of  financial  position,  depending  on  the  tax  jurisdiction  that  they  relate  to.  This  update  is  effective  for  financial  statements  issued  for  fiscal  years
beginning after December 15, 2016, and interim periods within those fiscal years, and may be applied either prospectively to all deferred tax assets and liabilities or retrospectively to all
periods presented. The Company elected to early-adopt this update on a retrospective basis, which resulted in $54.8 million of current deferred tax assets being reclassified to long-term as
of December 31, 2014. The adoption of this update had no effect on the Company’s results of operations. 

6. FAIR VALUE MEASUREMENT AND FINANCIAL INSTRUMENTS

The carrying  values of cash equivalents,  accounts receivable,  prepaid expenses and other current  assets, and accounts payable in the Company’s consolidated  balance sheets

approximated their fair values as of December 31, 2015 and 2014 due to their short-term nature.

Certain  of the  Company’s financial  instruments  are  measured  at fair  value  using a three-level  hierarchy  that  prioritizes  the  inputs  used to measure  fair  value.  This hierarchy

maximizes the use of observable inputs and minimizes the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows:

●

●

Level 1 - Inputs are quoted prices for identical instruments in active markets.

Level 2 -  Inputs  are  quoted  prices  for  similar  instruments  in  active  markets;  quoted  prices  for  identical  or  similar  instruments  in  markets  that  are  not  active;  or  model-
derived valuations whose inputs are observable or whose significant value drivers are observable.

●

Level 3 - Inputs are unobservable and reflect the Company's own assumptions, based on the best information available, including the Company's own data.

(1) The deferred compensation plan liability is a non-current liability recorded at the value of the amount owed to the plan participants, with changes in value recognized as a

compensation expense in the Company’s consolidated statements of income. The calculation of the deferred compensation obligation is derived from observable market data by
reference to hypothetical investments selected by the participants and is included in the line items captioned “Other non-current liabilities” on the Company’s consolidated
balance sheets. The Company invests in corporate-owned life insurance (“COLI”) policies, of which the cash surrender value is included in the line item captioned “Other non-
current assets” on the Company’s consolidated balance sheets.

(2) The difference between the amount shown as the carrying value in the above table and the amount shown on the Company’s consolidated balance sheet at December 31, 2015

represents the unamortized discounts related to deferred debt issuance costs and the bifurcation of the conversion feature of the Notes.

7. SHORT-TERM INVESTMENTS

Investments  consist  of  commercial  paper  and  corporate  bonds.  The  Company’s  policy  was  to  invest  in  only  high  quality  “AAA-rated”  or  investment-grade  securities.
Investments in debt securities were accounted for as “held-to-maturity” and were recorded at amortized cost, which approximates fair value, generally based upon observable market
values of similar securities. The Company has historically held all investments in debt securities until maturity, and has the ability and intent to continue to do so. All of the Company’s
investments had remaining contractual maturities of less than 12 months and were classified as short-term. Upon maturity, the Company used a specific identification method.

The Company had no short-term investments as of December 31, 2015. A summary of short-term investments as of December 31, 2014 is as follows (in thousands):

 As discussed in “Note 14. Debt”, on June 30, 2015, the Company issued an aggregate principal amount of $600.0 million of 2.00% Convertible Senior Notes due June 2022 in a
private placement offering (the “Notes”). Concurrently with the issuance of the Notes, the Company entered into convertible note hedge transactions with a financial institution (the “Note
Hedge Transactions”), which are generally expected to reduce the potential dilution to the Company’s stockholders and/or offset the cash payments the Company is required to make in
excess of the principal amount upon conversion of the Notes.

Derivative Asset

Pursuant to the Note Hedge Transactions, the Company purchased from the financial institution approximately 0.6 million call options on the Company’s common stock (the
“Bond Hedge Derivative Asset”), for which it paid consideration of $147.0 million. Each call option entitles the Company to purchase 15.7858 shares of the Company’s common stock at
an exercise price of $63.35 per share, is immediately exercisable, and has an expiration date of June 15, 2022, subject to earlier exercise.

The fair value of the Bond Hedge Derivative Asset at December 8, 2015 was $125.0 million, which was determined by a model-derived valuation utilizing Level 2 inputs which
are observable or whose significant value drivers are observable. The following table summarizes the inputs and assumptions used in the Black-Scholes model to calculate the fair value
of Bond Hedge Derivative Asset as of December 8, 2015:

As of the June 30, 2015 issuance date of the Notes, the Company did not have the necessary number of authorized but unissued shares of its common stock available to share-
settle the conversion option of the Notes. Therefore, in accordance with guidance found in ASC 470-20 and ASC 815-15, the conversion option of the Notes was deemed an embedded
derivative that required bifurcation from the Notes (host contract) and separate accounting as a derivative liability. The Company recorded the $167.0 million fair value of the conversion
option derivative liability as a debt discount at June 30, 2015 on the Company's consolidated balance sheet.

The Company held a Special Meeting of the Stockholders of the Company (the “Special Meeting”) on December 8, 2015, at which time the Company’s stockholders approved
an amendment  to the Restated  Certificate  of Incorporation  to increase  the number of authorized  shares of the Company’s  common  stock, par value  $0.01 per share, from  90,000,000
shares to 150,000,000 shares (the “Amendment”), which Amendment was subsequently filed with the Secretary of State of Delaware by the Company and effected. As a result of the
increase in the authorized shares of common stock, both the derivative asset and the derivative liability met the derivative scope exception and were reclassified to additional paid-in
capital, net of related taxes.

During the six month period ended December 31, 2015, the Company recognized in its consolidated statement of income $13.0 million of net expense related to the change in

the fair value of the derivative instruments before the liability was reclassified to equity as described above.

Inventory carrying value reserves were $24,136,000 and $25,639,000 at December 31, 2015 and 2014, respectively. During the three month period ended March 31, 2013, the
Company decided to discontinue the manufacture and distribution of certain unprofitable products after the Company conducted a strategic review of its currently manufactured generic
product portfolio. As a result of this decision, the Company recorded an inventory reserve of $6,700,000 related to the discontinued products. In addition, upon receipt of the Complete
Response Letter from the FDA for Rytary™ in January 2013, the Company evaluated the impact of the expected delay of FDA approval on its ability to sell the associated inventory. The
Company determined that a reserve of $5,000,000 was appropriate and recorded this amount in the three month period ended March 31, 2013. The Company subsequently received FDA
approval for Rytary™ on January 7, 2015. During the three month period ended March 31, 2013, the Company also recorded a $6,400,000 reserve for pre-launch inventory of a product
manufactured for another third-party pharmaceutical company due to the anticipated delayed launch of such product as a result of the warning letter related to the Company’s Hayward,
California manufacturing facility.

The Company recognizes pre-launch inventories at the lower of its cost or the expected net selling price. Cost is determined using a standard cost method, which approximates
actual cost, and assumes a FIFO flow of goods. Costs of unapproved products are the same as approved products and include materials, labor, quality control, and production overhead.
When the Company concludes FDA approval is expected within approximately six months, the Company will generally begin to schedule manufacturing process validation studies as
required by the FDA to demonstrate the production process can be scaled up to manufacture commercial batches. Consistent with industry practice, the Company may build quantities of
pre-launch inventories of certain products pending required final FDA approval and/or resolution of patent infringement litigation, when, in the Company’s assessment, such action is
appropriate  to  prepare  for  the  anticipated  commercial  launch,  FDA  approval  is  expected  in  the  near  term,  and/or  the  related  litigation  will  be  resolved  in  the  Company’s  favor.  The
capitalization of unapproved pre-launch inventory involves risks, including, among other items, FDA approval of product may not occur; approvals may require additional or different
testing and/or specifications than used for unapproved inventory; and, in cases where the unapproved inventory is for a product subject to litigation, the litigation may not be resolved or
settled  in favor  of the  Company.  If any  of these  risks  were to  materialize  and  the  launch  of  the  unapproved  product  delayed  or  prevented,  then  the  net carrying  value  of  unapproved
inventory may be partially or fully reserved. Generally, the selling price of a generic pharmaceutical product is at discount from the corresponding brand product selling price. Typically,
a generic drug is easily substituted for the corresponding brand product, and once a generic product is approved, the pre-launch inventory is typically sold within the next three months. If
the market prices become lower than the product inventory carrying costs, then the pre-launch inventory value is reduced to such lower market value. If the inventory produced exceeds
the estimated market acceptance of the generic product and becomes short-dated, a carrying value reserve will be recorded. In all cases, the carrying value of the Company's pre-launch
product inventory is lower than the respective estimated net selling prices. The carrying value of unapproved inventory less reserves was $8,658,000 and $7,312,000 at December 31,
2015 and 2014, respectively.

To the extent inventory is not scheduled to be utilized in the manufacturing process and/or sold within twelve months of the balance sheet date, it is included as a component of
other non-current assets. Amounts classified as non-current inventory consist of raw materials, net of valuation reserves. Raw materials generally have a shelf life of approximately three
to five years, while finished goods generally have a shelf life of approximately two years.

12. INTANGIBLE ASSETS AND GOODWILL

Intangible Assets

The  Company’s  finite  lived  intangible  assets  consist  of  marketed  product  rights  and  royalties  received  from  product  sales  from  the  Company's  third  party  partners.  The
Company’s indefinite lived intangible assets consist of acquired in-process research and development (IPR&D) product rights and acquired future royalty rights to be paid based on other
companies’ net sales of products not yet approved. Amortization over the estimated useful life will commence at the time of the respective product’s launch. If FDA approval to market
the product is not obtained, the Company will immediately expense the related capitalized cost. The following tables show the gross carrying values and accumulated amortization, where

As discussed  in “Note  2. Business Acquisition,”  the  substantial  increase  in  the Company’s  intangible  asset  balances  since  December  31, 2014 was attributable  to  the Tower

acquisition in March 2015.

In July 2015, the Company received an unsolicited offer from Turing Pharmaceuticals AG to purchase the U.S. rights to Daraprim®, one of the marketed products acquired in
the  Tower  acquisition,  as  well  as  the  active  pharmaceutical  ingredient  for  the  product  and  the  finished  goods  inventory  on  hand.  The  sale  closed  in  August  2015,  and  the  Company
received proceeds of $55.5 million at the closing. The net book value of the Daraprim® product rights at the time of the sale was $9.3 million. The Company recognized a gain on the sale
of the intangible asset of $45.6 million, net of expenses. Additionally in connection with the Tower acquisition, the Company acquired and then promptly resold at cost $4.0 million of
product rights which were required by the FTC to be divested as part of the FTC’s approval of the Tower acquisition.  

As a  result  of the  annual  intangible  asset  impairment  testing  performed  during  the  fourth  quarter  of  2015, the  Company  recorded  an  impairment  charge  of  $13.7 million,  of
which  $7.3  million  was  recorded  in  cost  of  revenues  and  $6.4  million  was  recorded  in  research  and  development  expenses  in  the  Company’s  consolidated  statement  of  income.  The
impairment charge was generally attributable to deteriorating market conditions for a small number of marketed products or, for acquired IPR&D product rights, a delay to the anticipated
product launch or an economic decision by management not to move forward with the development or marketing of a product. The Company recorded an impairment charge of $2.9
million to cost of revenues in the Company’s consolidated statement of income in 2014 as a result of continued severe price erosion on one of its market products, which price erosion
began in 2013. The Company recorded total impairment charges of $13.9 million in 2013, of which $13.1 million was recorded in cost of revenues and $0.8 million was recorded in
research and development expenses on the Company’s consolidated statement of income. These impairment charges related to one currently marketed product experiencing severe price
erosion due to new competition and one IPR&D product for which the ANDA was withdrawn.

The Company recognized amortization expense of $40.2 million, $11.1 million and $13.1 million for the years ended December 31, 2015, 2014 and 2013, respectively, in cost of
revenues in the consolidated statements of income presented. The following table shows the expected amortization of the Company’s finite lived intangible assets as of December 31,

Goodwill  on  the  Company’s  consolidated  balance  sheet  at  December  31,  2015  is  the  result  of  the  2015  Tower  acquisition  and  the  Company’s  1999  merger  of  Impax
Pharmaceuticals, Inc. with Global Pharmaceuticals Corporation. Goodwill had a carrying value of $210.2 million and $27.6 million at December 31, 2015 and 2014, respectively, and the
increase in the carrying value in 2015 was entirely attributable to the Tower acquisition. At December 31, 2015, the Company attributed $150.0 million and $60.2 million to the Impax
Generics division and the Impax Specialty Pharma division, respectively. At December 31, 2014, the Company attributed the entire carrying amount of goodwill to the Impax Generics
division. The Company concluded based on the results of the annual testing performed that the carrying value of goodwill was not impaired as of December 31, 2015 or 2014.

On  June  30,  2015,  the  Company  issued  an  aggregate  principal  amount  of  $600.0  million  of  2.00%  Convertible  Senior  Notes  due  June  2022  (the  “Notes”)  in  a  private
placement  offering,  which  are  the  Company’s  senior  unsecured  obligations.  The  Notes  were  issued  pursuant  to  an  Indenture  dated  June  30,  2015  (the  “Indenture”)  between  the
Company and Wilmington Trust, N.A., as trustee. The Indenture includes customary covenants and sets forth certain events of default after which the Notes may be due and payable
immediately. The Notes will mature on June 15, 2022, unless earlier redeemed, repurchased or converted. The Notes bear interest at a rate of 2.00% per year, and interest is payable
semiannually in arrears on June 15 and December 15 of each year, beginning on December 15, 2015.

The conversion rate for the Notes is initially set at 15.7858 shares per $1,000 of principal amount, which is equivalent to an initial conversion price of $63.35 per share of the
Company’s common stock. If a Make-Whole Fundamental Change (as defined in the Indenture) occurs or becomes effective prior to the maturity date and a holder elects to convert its
Notes in connection with the Make-Whole Fundamental Change, the Company is obligated to increase the conversion rate for the Notes so surrendered by a number of additional shares
of the Company’s common stock as prescribed in the Indenture. Additionally, the conversion rate is subject to adjustment in the event of an equity restructuring transaction such as a
stock dividend, stock split, spinoff, rights offering, or recapitalization through a large, nonrecurring cash dividend (“standard antidilution provisions,” per ASC 815-40 – Contracts in
Entity’s Own Equity).

The Notes are convertible at the option of the holders at any time prior to the close of business on the business day immediately preceding December 15, 2021 only under the

following circumstances:

(i)

(ii)

If  during  any  calendar  quarter  commencing  after  the  quarter  ending  September  30,  2015  (and  only  during  such  calendar  quarter)  the  last  reported  sale  price  of  the
Company’s common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the
immediately preceding calendar quarter is greater than 130% of the conversion price on each applicable trading day; or
If during the five business day period after any 10 consecutive trading day period (the “measurement period”) in which the trading price per $1,000 of principal amount
of  Notes  for  each  trading  day  of  the  measurement  period  was  less  than  98%  of  the  product  of  the  last  report  sale  price  of  the  Company’s  common  stock  and  the
conversion rate on each such trading day; or

(iii) Upon the occurrence of corporate events specified in the Indenture.

On or after December 15, 2021 until the close of business on the second scheduled trading day immediately preceding the maturity date, the holders may convert their Notes at
any time, regardless of the foregoing circumstances. The Company may satisfy its conversion obligation by paying or delivering, as the case may be, cash, shares of the Company’s
common stock, or a combination of cash and shares of the Company’s common stock, at the Company’s election and in the manner and subject to the terms and conditions provided in
the Indenture.

Concurrently with the offering of the Notes and using a portion of the proceeds from the sale of the Notes, the Company entered into a series of convertible note hedge and
warrant transactions (the “Note Hedge Transactions” and “Warrant Transactions”) which are designed to reduce the potential dilution to the Company’s stockholders and/or offset the
cash payments the Company is required to make in excess of the principal amount upon conversion of the Notes. The Note Hedge Transactions and Warrant Transactions are separate
transactions, in each case, entered into by the Company with a financial institution and are not part of the terms of the Notes. These transactions will not affect any holder’s rights under
the Notes, and the holders of the Notes have no rights with respect to the Note Hedge Transactions and Warrant Transactions. See “Note 8, Derivatives” and “Note 15, Stockholders’
Equity” for additional information.

At  the  June  30,  2015  issuance  date  of  the  Notes,  the  Company  did  not  have  the  necessary  number  of  authorized  but  unissued  shares  of  its  common  available  to  settle  the
conversion option of the Notes in shares of the Company’s common stock. Therefore, in accordance with guidance found in ASC 470-20 – Debt with Conversion and Other Options
(“ASC 470-20”) and ASC 815-15 – Embedded Derivatives (“ASC 815-15”), the conversion option of the Notes was deemed an embedded derivative requiring bifurcation from the
Notes  (host  contract)  and  separate  accounting  as  a  derivative  liability.  The  fair  value  of  the  conversion  option  derivative  liability  at  June  30,  2015  was  $167.0  million,  which  was
recorded as a reduction to the carrying value of the debt. This debt discount will be amortized to interest expense over the term of the debt using the effective interest method. Although
the Company received stockholder approval on December 8, 2015 to amend the Company’s Restated Certificate of Incorporation to increase the authorized number of shares of the
Company’s common stock (which amendment has occurred), the debt discount remains and continues to be amortized to interest expense. The effect of the increase in the authorized
share count on the derivative liability is discussed in “Note 8, Derivatives.”

In  connection  with  the  issuance  of  the  Notes,  the  Company  incurred  approximately  $18.7  million  of  debt  issuance  costs  for  banking,  legal  and  accounting  fees  and  other
expenses.  This  amount  was  also  recorded  on  the  Company’s  balance  sheet  as  a  reduction  to  the  carrying  value  of  the  debt,  in  accordance  with  the  Company’s  early  adoption  of
Accounting Standards Update (“ASU”) No. 2015-03 – Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-03”), and will be amortized to interest expense over the term of
the debt using the effective interest method.

For the year ended December 31, 2015, the Company recognized $16.3 million of interest expense related to the Notes, of which $6.0 million was cash and $10.3 million was
non-cash  accretion  of  the  debt  discounts  recorded.  As  the  Notes  mature  in  2022,  they  have  been  classified  as  long-term  debt  on  the  Company’s  consolidated  balance  sheet,  with  a
carrying value of approximately $424.6 million as of December 31, 2015.

Royal Bank of Canada $100.0 Million Revolver

On August 4, 2015, the Company entered into a senior secured revolving credit facility (the “Revolving Credit Facility”) of up to $100 million, pursuant to a credit agreement,
by  and  among  the  Company,  the  lenders  party  thereto  from  time  to  time  and  Royal  Bank  of  Canada,  as  administrative  agent  and  collateral  agent  (the  “Revolving  Credit  Facility
Agreement”). The Revolving Credit Facility is available for working capital and other general corporate purposes. Borrowings under the Revolving Credit Facility will accrue interest at
a rate equal to LIBOR or the base rate, plus an applicable margin. The applicable margin may be increased or reduced by 0.75% based on the Company’s total net leverage ratio. The
Revolving Credit Facility will mature on August 4, 2020. No borrowings have been drawn from the Revolving Credit Facility during the year ended December 31, 2015.

Loss on Early Extinguishment of Debt – Barclays $435.0 Million Term Loan

In connection with the acquisition of Tower during the first quarter of 2015, the Company entered into a $435.0 million senior secured term loan facility (the “Term Loan”)
and a $50.0 million senior secured revolving credit facility (the “Barclays Revolver” and collectively with the Term Loan, the “Barclays Senior Secured Credit Facilities”), pursuant to
a credit agreement, dated as of March 9, 2015, by and among the Company, the lenders party thereto from time to time and Barclays Bank PLC, as administrative and collateral agent
(the “Barclays Credit Agreement”). In connection with the Barclays Senior Secured Credit Facilities, the Company incurred debt issuance costs for banking, legal and accounting fees
and other expenses of approximately $17.8 million. Prior to repayment of the Term Loan on June 30, 2015, these debt issuance costs were to be amortized to interest expense over the
term of the loan using the effective interest rate method.

F-31

 
 
 
 
 
 
 
 
 
 
 
On June 30, 2015, the Company used approximately $436.4 million of the proceeds from the sale of the Notes to repay the $435.0 million of principal and approximately $1.4
million  of  accrued  interest  due  on  its  Term  Loan  under  the  Barclays  Credit  Agreement.  In  connection  with  this  repayment  of  the  loan,  the  Company  recorded  a  loss  on  early
extinguishment of debt of approximately $16.9 million related to the unamortized portion of the deferred debt issuance costs during the quarter ended June 30, 2015.

For the six months ended June 30, 2015, the Company incurred total interest expense on the Term Loan of approximately $10.7 million, of which $9.8 million was cash and
$0.9  million  was  non-cash  amortization  of  the  deferred  debt  issuance  costs.  Included  in  the  2015  year-to-date  cash  interest  expense  of  $15.8  million  is  approximately  $2.3  million
related to a ticking fee paid to Barclays during the first quarter of 2015, prior to the funding of the Senior Secured Credit Facilities on March 9, 2015, to lock in the financing terms from
the lenders’ commitment of the Term Loan until the actual allocation of the loan occurred.

15. STOCKHOLDERS’ EQUITY

Preferred Stock

Pursuant to its Restated Certificate of Incorporation (the “Certificate of Incorporation”), the Company is authorized to issue 2,000,000 shares of “blank check” preferred stock,
$0.01 par value per share, which enables the Board of Directors, from time to time, to create one or more new series of preferred stock. Each series of preferred stock issued can have the
rights, preferences, privileges and restrictions designated by the Board of Directors. The issuance of any new series of preferred stock could affect, among other things, the dividend,
voting, and liquidation rights of the Company’s common stock. The Company had no preferred stock issued or outstanding as of December 31, 2015 or 2014. 

Common Stock

A  Special  Meeting  of  the  Stockholders  of  the  Company  (the  “Special  Meeting”)  occurred  on  December  8,  2015,  at  which  time  the  Company’s  stockholders  approved  an
amendment to the Restated Certificate of Incorporation to increase the number of authorized shares of the Company’s common stock, par value $0.01 per share, from 90,000,000 shares
to 150,000,000 shares (the “Amendment”), which Amendment was subsequently filed with the Secretary of State of Delaware by the Company and effected. At December 31, 2015, the
Company had 72,926,205 shares of its common stock issued and 72,682,476 shares of its common stock outstanding. In addition, the Company had reserved for issuance the following
amounts of shares of its common stock for the purposes described below as of December 31, 2015 (in thousands):

As discussed in “Note 14. Debt”, on June 30, 2015, the Company entered into a series of Note Hedge Transactions and Warrant Transactions with a financial institution which

are designed to reduce the potential dilution to the Company’s stockholders and/or offset the cash payments the Company is required to make in excess of the principal amount upon
conversion of the Notes. Pursuant to the Warrant Transactions, the Company sold to a financial institution 9.47 million warrants to purchase the Company’s common stock, for which it
received proceeds of $88.3 million. The warrants have an exercise price of $81.277 per share (subject to adjustment), are immediately exercisable, and have an expiration date of
September 15, 2022.

Additional paid-in capital

As a result of the Amendment and the increase in the number of authorized shares of the Company's common stock described above, both the derivative asset and the derivative
liability met the derivative scope exception and were reclassified to additional paid-in capital. The net effect of the reclassification of the derivatives and the related tax effect was a $21
million increase in additional paid-in capital on the Company's consolidated balance sheet. 

16. EARNINGS PER SHARE

The  Company's  basic  earnings  per  common  share  (“EPS”)  is  computed  by  dividing  net  income  available  to  the  Company’s  common  stockholders  (as  presented  on  the
consolidated statements of income) by the weighted-average number of shares of the Company’s common stock outstanding during the period. The Company’s restricted stock awards
(non-vested shares) are issued and outstanding at the time of grant but are excluded from the Company’s computation of weighted-average shares outstanding in the determination of
basic EPS until vesting occurs.

For purposes of calculating diluted EPS, the denominator includes both the weighted-average number of shares of common stock outstanding and the number of common stock
equivalents if the inclusion of such common stock equivalents would be dilutive. Dilutive common stock equivalents potentially include warrants, stock options and non-vested restricted
stock awards using the treasury stock method and the number of shares of common stock issuable upon conversion of the Company’s outstanding convertible notes payable. In the case of
the Company’s outstanding convertible notes payable, the diluted EPS calculation is further affected by an add-back of interest expense, net of tax, to the numerator under the assumption
that the interest would not have been incurred if the convertible notes had been converted into common stock.

(1) The numerator and denominator adjustments related to the Company’s convertible notes payable were excluded from the computation because the add-back of interest

expense, net of tax, to the numerator had a greater effect on the quotient than the inclusion of the incremental shares assuming conversion of the convertible notes payable in
the denominator, resulting in anti-dilution.

(2) Not applicable to the period presented.

(3) As of December 31, 2015, the approximately 9.47 million warrants outstanding have been excluded from the denominator of the diluted EPS computation under the treasury
stock method because the exercise price of the warrants exceeds the average market price of the Company’s common stock for the period, so inclusion in the calculation
would be anti-dilutive.

million for warrants to purchase the Company’s common stock and 9.47 million shares for conversion of outstanding convertible senior notes payable. In addition, for the
year ended December 31, 2015, the Company excluded from the computation as anti-dilutive 1,688,266 and 1,521,097 shares issuable upon the exercise of stock options
and vesting of non-vested restricted stock awards, respectively.

(5) For the year ended December 31, 2014, the Company excluded 946,288 stock options from the computation of diluted net income per common share as the effect of these

options would have been anti-dilutive.

(6) For the year ended December 31, 2013, the Company excluded 1,741,110 stock options from the computation of diluted net income per common share as the effect of

these options would have been anti-dilutive.

17. SHARE-BASED COMPENSATION

The Company recognizes the grant date fair value of each option and restricted share over its vesting period. Options and restricted shares granted under the Company’s Second

awards, which will be recognized over a weighted average period of 2.15 years. The intrinsic value of options exercised during the years ended December 31, 2015, 2014 and 2013 was
$33,043,000,  $10,423,000  and  $8,780,000,  respectively.  The  total  fair  value  of  restricted  shares  which  vested  during  the  years  ended  December  31,  2015,  2014  and  2013  was
$21,061,000, $16,959,000 and $11,604,000, respectively.

The  Company  estimated  the  fair  value  of  each  stock  option  award  on  the  grant  date  using  the  Black-Scholes  option  pricing  model,  wherein  expected  volatility  is  based  on
historical volatility of the Company’s common stock. The expected term calculation is based on the “simplified” method described in SAB No. 107, Share-Based Payment and SAB No.
110,  Share-Based  Payment,  as  the  result  of  the  simplified  method  provides  a  reasonable  estimate  in  comparison  to  actual  experience.  The  risk-free  interest  rate  is  based  on  the  U.S.
Treasury yield at the date of grant for an instrument with a maturity that is commensurate with the expected term of the stock options. The dividend yield of zero is based on the fact that
the Company has never paid cash dividends on its common stock, and has no present intention to pay cash dividends. Options granted under each of the above plans generally vest from
three to four years and have a term of ten years.

The amount of share-based compensation expense recognized by the Company is as follows (in thousands):

In June 2013, the Company announced that Dr. Larry Hsu planned to retire as President and Chief Executive Officer of Impax and in April 2014, Dr. Hsu retired from those
positions  at  Impax.  Pursuant  to  his  Separation  Agreement,  all  option  grants  and  restricted  stock  grants  expected  to  vest  in  the  12  month  period  following  his  retirement  date  were
accelerated and vested as of the retirement date. As a result, during the three month period ended June 30, 2013, the Company recorded $2.3 million of accelerated expense related to Dr.
Hsu’s outstanding stock options and restricted stock.

On  April  21,  2014,  the  Board  of  Directors  of  the  Company  announced  that  it  had  appointed  Fred  Wilkinson  as  the  Company’s  new  President  and  Chief  Executive  Officer
effective as of April 29, 2014. In accordance with Mr. Wilkinson’s employment agreement, the Company granted 150,000 shares of the Company’s restricted stock with a grant date fair
value of $3.9 million, which vested as to one-third of the underlying shares on each of the first three six-month anniversaries of April 29, 2014, subject to Mr. Wilkinson’s continued
employment  with the Company on such vesting date. Further, Mr. Wilkinson  also received  an award of 375,000 shares of restricted  stock that will vest in three  tranches  based upon
continued service by Mr. Wilkinson to the Company and the achievement of certain performance criteria as set forth in his employment agreement. The Company valued these restricted
stock awards using a Monte Carlo simulation and is recognizing the $7.6 million value of these awards over the longer of the derived or explicit service period, which is two years.

On October 22, 2014, the Company announced that Carole S. Ben-Maimon, M.D., President of the Company’s Impax Generics division, informed the Company of her decision
to  retire  from  her  position  effective  November  3,  2014.  Pursuant  to  her  Separation  Agreement,  all  option  grants  and  restricted  stock  grants  expected  to  vest  in  the  12  month  period
following her retirement date were accelerated and vested as of the retirement date. As a result, during the three month period ended December 31, 2014, the Company recorded $0.5
million of accelerated expense related to Dr. Ben-Maimon’s outstanding stock options and restricted stock.

The after tax impact of recognizing the share-based compensation expense related to FASB ASC Topic 718 on basic earnings per common share was $0.20, $0.20 and $0.19 for
the years ended December 31, 2015, 2014 and 2013, respectively, and diluted earnings per common share was $0.20, $0.20 and $0.19 for the years ended December 31, 2015, 2014 and
2013,  respectively.  The  Company  recognized  a  deferred  tax  benefit  of  $9,150,000,  $6,880,000  and  $4,829,000  in  the  years  ended  December  31,  2015,  2014  and  2013,  respectively,
related to share-based compensation expense recorded for non-qualified employee stock options and restricted stock awards.

The Company’s policy is to issue new shares to satisfy stock option exercises and to grant restricted share awards. There were no modifications, other than discussed above, to

any stock options during the years ended December 31, 2015, 2014 or 2013.

18. EMPLOYEE BENEFIT PLANS

401(k) Defined Contribution Plan

The  Company  sponsors  a  401(k)  defined  contribution  plan  covering  all  employees.  Participants  are  permitted  to  contribute  up  to  25%  of  their  eligible  annual  pre-tax
compensation up to established federal limits on aggregate participant contributions. Prior to January 1, 2015, the Company matched 50% of the employee contributions up to a maximum
of 6% of employee compensation. Effective January 1, 2015, the Company updated its 401(k) policy to match 100% of the employee contributions up to a maximum of 5% of employee
compensation. Discretionary profit-sharing contributions made by the Company, if any, are determined annually by the Board of Directors. Participants are 100% vested in discretionary
profit-sharing and matching contributions made by the Company after three years of service, and are 25% and 50% vested after one and two years of service, respectively. There were
$3,656,000, $1,615,000 and $1,501,000 in matching contributions and no discretionary profit-sharing contributions made under this plan for the years ended December 31, 2015, 2014
and 2013, respectively.

Employee Stock Purchase Plan

In February 2001, the Board of Directors approved the 2001 Non-Qualified Employee Stock Purchase Plan (“ESPP”), with a 500,000 share reservation. The purpose of the ESPP
is to enhance employee interest in the success and progress of the Company by encouraging employee ownership of common stock of the Company. The ESPP provides the opportunity
to purchase the Company’s common stock at a 15% discount to the market price through payroll deductions or lump sum cash investments. Under the ESPP plan, for the years ended
December  31,  2015,  2014  and  2013,  the  Company  sold  shares  of  its  common  stock  to  its  employees  in  the  amount  of  35,275,  35,350  and  39,748,  respectively,  for  net  proceeds  of
$1,184,000, $788,000 and $660,000, respectively.

Deferred Compensation Plan

In February 2002, the Board of Directors approved the Executive Non-Qualified Deferred Compensation Plan (“ENQDCP”) effective August 15, 2002 covering executive level
employees  of  the  Company  as  designated  by  the  Board  of  Directors.  Participants  can  defer  up  to  75%  of  their  base  salary  and  quarterly  sales  bonus  and  up  to  100%  of  their  annual
performance  based  bonus. The Company  matches  50%  of  employee  deferrals  up to  10%  of  base  salary  and bonus  compensation.  The  maximum  total  match  by the  Company  cannot
exceed  5%  of  total  base  and  bonus  compensation.  Participants  are  vested  in  the  employer  match  contribution  at  20%  each  year,  with  100%  vesting  after  five  years  of  employment.
Participants can earn a return on their deferred compensation based on hypothetical investments in investment funds. Changes in the market value of the participant deferrals and earnings
thereon are reflected as an adjustment to the liability for deferred compensation with an offset to compensation expense. There were $1,098,000, $850,000 and $764,000 in matching
contributions under the ENQDCP for the years ended December 31, 2015, 2014 and 2013, respectively.

F-38

 
 
 
 
 
 
 
 
 
 
 
 
 
The deferred compensation liability is a non-current liability recorded at the value of the amount owed to the ENQDCP participants, with changes in the value of such amounts
recognized as a compensation expense in the consolidated statement of operations. The calculation of the deferred compensation obligation is derived from observable market data by
reference to hypothetical investments selected by the participants and is included in the line item captioned “Other liabilities” on the consolidated balance sheets. The Company invests in
corporate  owned  life  insurance  (“COLI”)  policies,  of  which  the  cash  surrender  value  is  included  in  the  line  item  captioned  “Other  assets”  on  the  consolidated  balance  sheets.  As  of
December 31, 2015 and 2014, the Company had a cash surrender value asset of $30,726,000 and $29,241,000, respectively, and a deferred compensation liability of $25,581,000 and
$25,837,000, respectively, which approximated fair value. The asset representing the cash surrender value of the corporate owned life insurance and the deferred compensation liability
are both Level 2 fair value measurements.

On January 3, 2013, the research and development credit (the “R&D credit”) was reinstated retroactively as a part of The American Taxpayer Relief Act of 2012 for expenses
paid or incurred from January 1, 2012 through December 31, 2012. Due to the fact that this legislation was not enacted prior to the Company’s 2012 year-end, no tax benefit related to
potential  R&D credits  was reflected  within  the 2012  year-end  tax  provision.  The  2012 R&D credit  was  reflected  within  the  Company’s  first  quarter  tax provision  for the  year  ended
December 31, 2013.

Deferred income taxes result from temporary differences between the financial statement carrying values and the tax bases of the Company’s assets and liabilities. Deferred tax
assets principally result from deferred revenue related to certain of the Company’s alliance and collaboration agreements (see “Note 20. Alliance and Collaboration Agreements” below
for a discussion of the Company's alliance and collaboration agreements), certain accruals and reserves currently not deductible for tax purposes, acquired product rights and intangibles,
capitalized  legal  and  share  based  compensation  expense.  Deferred  tax  liabilities  principally  result  from  the  use  of  accelerated  depreciation  methods  for  income  tax  purposes.  The
components of the Company’s deferred tax assets and liabilities are as follows (in thousands):

Deferred tax assets:
Deferred revenues
Accrued expenses
Inventory reserves

The amount of unrecognized tax benefits at December 31, 2015, 2014 and 2013 was $5.7 million, $6.5 million and $5.3 million respectively, of which $4.3 million, $5.0 million
and $4.1 million would impact the Company’s effective tax rate, respectively, if recognized. The Company currently does not believe that the total amount of unrecognized tax benefits
will increase or decrease significantly over the next 12 months. Interest expense related to income taxes is included in “Interest expense” on the consolidated statement of operations. Net
interest expense related to unrecognized tax benefits for the year ended December 31, 2015 was $8,000 principally due to the settlement of the 2010-2011 California audit and the filing
of a Tennessee Voluntary Disclosure Agreement for the years 2011-2014, compared to $5,000 in 2014. Accrued interest expense as of December 31, 2015 and 2014 was $589,000 and
$597,000, respectively. Income tax penalties are included in “Other income (expense)” on the consolidated statements of operations. Accrued tax penalties of $598,000 were booked in
2015 related to the 2010-2011 California audit.

The Company is currently not under audit for its federal income tax. No provision has been made for U.S. federal deferred income taxes on accumulated earnings on foreign

subsidiaries since it is the current intention of management to indefinitely reinvest the undistributed earnings in the foreign subsidiary.

20 . ALLIANCE AND COLLABORATION AGREEMENTS

The Company has entered into several alliance, collaboration, license and distribution agreements, and similar agreements with respect to certain of its products and services,
with unrelated third-party  pharmaceutical  companies.  The statement of operations  includes revenue  recognized under agreements  the Company has entered into to develop marketing
and/or distribution relationships with its partners to fully leverage the technology platform of the Company or of such third party partners and revenue recognized under development
agreements which generally obligate the Company to provide research and development services over multiple periods, and revenue recognized under a promotional services agreement
which obligates the Company or the third party partner to provide research and development services over multiple periods.

The  Company’s  alliance  and  collaboration  agreements  often  include  milestones  and  provide  for  milestone  payments  upon  achievement  of  these  milestones.  Generally,  the
milestone events contained in the Company’s alliance and collaboration agreements coincide with the progression of the Company’s or the partner’s products and technologies from pre-
commercialization to commercialization.

The  Company  groups  pre-commercialization  milestones  in  its  alliance  and  collaboration  agreements  into  clinical  and  regulatory  categories,  each  of  which  may  include  the

following types of events:

Clinical Milestone Events:
● Designation of a development candidate . Following the designation of a development candidate, generally, IND-enabling animal studies for a new development candidate

take 12 to 18 months to complete.

●

Initiation of a Phase I clinical trial . Generally, Phase I clinical trials take one to two years to complete.

●

Initiation or completion of a Phase II clinical trial . Generally, Phase II clinical trials take one to three years to complete.

Initiation or completion of a Phase III clinical trial . Generally, Phase III clinical trials take two to four years to complete.

● Completion of a bioequivalence study . Generally, bioequivalence studies take three months to one year to complete.

Regulatory Milestone Events:
●

Filing or acceptance of regulatory applications for marketing approval such as a New Drug Application in the United States or Marketing Authorization Application in
Europe . Generally, it takes six to 12 months to prepare and submit regulatory filings and approximately two months for a regulatory filing to be accepted for substantive
review.

● Marketing approval in a major market, such as the United States or Europe . Generally it takes one to three years after an application is submitted to obtain approval from

the applicable regulatory agency.

● Marketing approval in a major market, such as the United States or Europe for a new indication of an already-approved product . Generally it takes one to three years after

an application for a new indication is submitted to obtain approval from the applicable regulatory agency.

Commercialization milestones in the Company’s alliance and collaboration agreements may include the following types of events:

●

●

First commercial sale in a particular market , such as in the United States or Europe .

Product sales in excess of a pre-specified threshold , such as annual sales exceeding $100 million . The amount of time to achieve this type of milestone depends on several
factors including but not limited to the dollar amount of the threshold, the pricing of the product and the pace at which customers begin using the product.

License and Distribution Agreement with Shire

In January 2006, the Company entered into a License and Distribution Agreement with an affiliate of Shire Laboratories, Inc., which was subsequently amended (“Prior Shire
Agreement”), under which the Company received a non-exclusive license to market and sell an authorized generic of Shire’s Adderall XR® product (“AG Product”) subject to certain
conditions, but in any event by no later than January 1, 2010. The Company commenced sales of the AG Product in October 2009. On February 7, 2013, the Company entered into an
Amended and Restated License and Distribution Agreement with Shire (the “Amended and Restated Shire Agreement”), which amended and restated the Prior Shire Agreement. The
Amended and Restated Shire Agreement was entered into by the parties in connection with the settlement of the Company’s litigation with Shire relating to Shire’s supply of the AG
Product to the Company under the Prior Shire Agreement. During 2013, the Company received a payment of $48,000,000 from Shire in connection with such litigation settlement, which
was recorded in the first quarter of 2013 under the line item “Other Income” on the consolidated statement of operations. Under the Amended and Restated Shire Agreement, Shire was
required to supply the AG Product and Company was responsible for marketing and selling the AG Product subject to the terms and conditions thereof until the earlier of (i) the first
commercial sale of the Company’s generic equivalent product to Adderall XR® and (ii) September 30, 2014 (the “Supply Term”), subject to certain continuing obligations of the parties
upon expiration or early termination of the Supply Term, including Shire’s obligation to deliver AG Products still owed to the Company as of the end of the Supply Term. The Company
is required to pay a profit share to Shire on sales of the AG Product, of which the Company owed a profit share payable to Shire of $19,540,000, $21,089,000 and $20,406,000 on sales of
the AG Product during the years ended December 31, 2015, 2014 and 2013, respectively, with a corresponding charge included in the cost of revenues line in the consolidated statement
of operations. Although the Supply Term expired on September 30, 2014, the Company was permitted to sell any AG Products in its inventory or owed to the Company by Shire under
the  Amended  and  Restated  Shire  Agreement  until  all  such  products  are  sold.  The  Company  continued  to  pay  a  profit  share  to  Shire  on  sales  of  such  products  during  the  year  ended
December 31, 2015.

Development, Supply and Distribution Agreement with TOLMAR, Inc.

In June 2012, the Company entered into the Tolmar Agreement with Tolmar. Under the terms of the Tolmar Agreement, Tolmar granted to the Company an exclusive license to
commercialize  up  to  11  generic  topical  prescription  drug  products,  including  ten  then  approved  products  and  one  product  pending  approval  at  the  FDA,  in  the  United  States  and  its
territories. Under the terms of the Tolmar Agreement, Tolmar is responsible for developing and manufacturing the products, and the Company is responsible for marketing and sale of the
products. The Company is required to pay a profit share to Tolmar on sales of each product commercialized pursuant to the terms of the Tolmar Agreement.

The Company paid Tolmar a $21 million upfront payment upon signing of the agreement and, pursuant to the terms of the agreement, is also required to make payments to
Tolmar upon the achievement of certain specified milestone events. Such contingent milestone payments will initially be recognized in the period the triggering event occurs. Milestone
payments  which  are  contingent  upon  commercialization  events  will  be  accounted  for  as  an  additional  cost  of  acquiring  the  product  license  rights.  Milestone  payments  which  are
contingent upon regulatory approval events will be capitalized and amortized over the remaining estimated useful life of the approved product. During the year ended December 31, 2012,
the Company made a $1.0 million milestone payment and, during the fourth quarter of 2013, the Company made a $12.0 million payment to Tolmar upon Tolmar’s achievement of a
regulatory milestone event in accordance with the terms of pursuant to the Tolmar Agreement. The $21 million upfront payment for the Tolmar product rights has been allocated to the
underlying topical products based upon the relative fair value of each product and will be amortized over the remaining estimated useful life of each underlying product, ranging from five
to  12  years,  starting  upon  commencement  of  commercialization  activities  by  the  Company  during  the  second  half  of  2012.  The  amortization  of  the  Tolmar  product  rights  has  been
included as a component of cost of revenues on the consolidated statement of operations. The Company initially allocated $1.55 million of the upfront payment to two products which
were in development and has recorded such amount as in-process research and development expense in its results of operations for the year ended December 31, 2012. The Company
similarly recorded the $1,000,000 milestone paid in the year ended December 31, 2012 as a research and development expense. The Company is required to pay a profit share to Tolmar
on sales of the topical products, of which the Company owed a profit share payable to Tolmar of $77,683,000, $15,995,000 and $3,905,000 during the years ended December 31, 2015,
2014 and 2013, respectively, with a corresponding charge included in the cost of revenues line in the Company’s consolidated statement of operations. During the fourth quarter of 2014,
the Company paid a $2.0 million milestone related to the Diclofenac Sodium Gel 3% or Solaraze® product to Tolmar pursuant to the Tolmar Agreement. During the second quarter of
2015, the Company paid a $5.0 million milestone related to certain topical products pursuant to the Tolmar Agreement.

As discussed in “Note 12. Goodwill and Intangible Assets,” the Company recorded a $13.1 million intangible asset impairment charge to cost of revenues in the three month

period ended September 30, 2013 related to the Tolmar product rights acquired under the Tolmar Agreement.  

The Company entered into a Loan and Security Agreement with Tolmar in March 2012 (the “Tolmar Loan Agreement”), under which the Company agreed to lend to Tolmar
one or more loans through December 31, 2014, in an aggregate amount not to exceed $15,000,000. As of December 31, 2015 and 2014, Tolmar owed the Company $15,000,000 under
the Tolmar Loan Agreement, which is included in “Other Assets” on the consolidated balance sheets. The outstanding principal amount of, including any accrued and unpaid interest on,
the loans under the Tolmar Loan Agreement are payable by Tolmar beginning from March 31, 2017 through March 31, 2020 or the maturity date, in accordance with the terms therein.
Tolmar may prepay all or any portion of the outstanding balance of the loans prior to the maturity date without penalty or premium.

Strategic Alliance Agreement with Teva

The Company entered  into a Strategic  Alliance  Agreement  with Teva Pharmaceuticals  Curacao  N.V., a subsidiary  of Teva Pharmaceutical  Industries  Limited,  in June 2001,
which was subsequently amended (“Teva Agreement”). The Teva Agreement commits the Company to develop and manufacture, and Teva to distribute, a specified number controlled
release generic pharmaceutical products (“generic products”), each for a 10-year period. The Company is required to develop the products, obtain FDA approval to market the products,
and  manufacture  the  products  for  Teva.  The  revenue  the  Company  earns  from  the  sale  of  product  under  the  Teva  Agreement  consists  of  Teva’s  reimbursement  of  the  Company’s
manufacturing costs plus a profit share on Teva’s sales of the product to its customers. The Company invoices Teva for the manufacturing costs or products it ships to Teva and payment
is due within 30 days. Teva has the right to determine all terms and conditions of the product sales to its customers. Within 30 days of the end of each calendar quarter, Teva is required to
provide the Company with a report of its net sales and profits during the quarter and to pay the Company its share of the profits resulting from those sales. Net sales are Teva’s gross sales
less discounts, rebates, chargebacks, returns, and other adjustments, all of which are based upon fixed percentages, except chargebacks, which are estimated by Teva and subject to a true-
up reconciliation.

F-43

 
 
 
 
 
 
 
 
 
 
As of December 31, 2015, the Company was supplying Teva with oxybutynin extended release tablets (Ditropan XL® 5 mg, 10 mg and 15 mg extended release tablets) and has
agreed to supply another product (currently under development) to Teva; the other products under the Teva Agreement have either been returned to the Company, are being manufactured
by Teva at its election, were voluntarily withdrawn from the market the Company’s obligations to supply such product had expired or were terminated in accordance with the agreement.

OTC Partner Alliance Agreement

In June 2002, the Company entered into a Development, License and Supply Agreement with Pfizer, Inc., formerly Wyeth LLC (“Pfizer”), for a term of approximately 15 years,
relating to the Company’s Loratadine and Pseudoephedrine Sulfate 5 mg/120 mg 12-hour Extended Release Tablets and Loratadine and Pseudoephedrine Sulfate 10 mg/240 mg 24-hour
Extended  Release  Tablets  for  the  OTC  market.  The  Company  previously  developed  the  products,  and  is  currently  only  responsible  for  manufacturing  the  products,  and  Pfizer  is
responsible for marketing and sale. The agreement included payments to the Company upon achievement of development milestones, as well as royalties paid to the Company by Pfizer
on  its  sales  of  the  product.  Pfizer  launched  this  product  in  May  2003  as  Alavert®  D-12  Hour.  In  February  2005,  the  agreement  was  partially  cancelled  with  respect  to  the  24-hour
Extended Release Product due to lower than planned sales volume. In December 2011, Pfizer and the Company entered into an agreement with L. Perrigo Company (“Perrigo”) whereby
the  parties  agreed  that  the  Company  would  supply  the  Company’s  generic  Claritin-D®  5  mg/120  mg  12-hour  extended  release  product  tablets  to  Perrigo  in  the  United  States  and  its
territories. The agreements with Pfizer and Perrigo are no longer a core area of the Company’s business, and the over-the-counter pharmaceutical products the Company sells to Pfizer
and Perrigo under the agreements are older products which are only sold to Pfizer and Perrigo. As noted above, the Company is currently only required to manufacture the products under
its agreements with Pfizer and Perrigo. The Company recognizes profit share revenue in the period earned.

Agreements with Valeant Pharmaceuticals International, Inc.

In November 2008, the Company and Valeant Pharmaceuticals International, Inc., formerly Medicis Pharmaceutical Corporation (“Valeant”), entered into a Joint Development

Agreement and a License and Settlement Agreement (“Joint Development Agreement”).

Joint Development Agreement

The  Joint  Development  Agreement  provides  for  the  Company  and  Valeant  to  collaborate  in  the  development  of  a  total  of  five  dermatology  products,  including  four  of  the
Company’s generic products and one branded advanced form of Valeant’s SOLODYN® product. Under the provisions of the Joint Development Agreement the Company received a $40
million  upfront  payment  upon  signing  of  the  Joint  Development  Agreement  in  December  2008.  The  Company  has  also  received  an  aggregate  of  $15,000,000  in  milestone  payments
composed of two $5 million milestone payments, paid by Valeant in March 2009 and September 2009, a $2 million milestone payment paid by Valeant in December 2009, and a $3
million milestone payment paid by Valeant in March 2011. The Company has the potential to receive up to an aggregate of $8 million of additional contingent milestone payments, upon
the achievement of certain specified regulatory events, each of which the Company believes to be substantive, as well as the potential to receive royalty payments from sales, if any, by
Valeant  of  its  advanced  form  SOLODYN®  brand  product.  Finally,  to  the  extent  the  Company  commercializes  any  of  its  four  generic  dermatology  products  covered  by  the  Joint
Development  Agreement,  the Company will pay to Valeant a gross profit share  on sales of such products. The Company began selling  one of the four generic  dermatology  products
during the year ended December 31, 2011. As of December 31, 2014, the full amount of deferred revenue under the Joint Development Agreement was recognized.

F-44

 
 
 
 
 
 
 
 
 
 
The Joint Development Agreement results in three items of revenue for the Company, as follows:

(1) Research  &  Development  Services.  Revenue  received  from  the  provision  of  research  and  development  services  including  the  $40,000,000  upfront  payment  and  the
$12,000,000  of  milestone  payments  received  prior  to  January  1,  2011,  have  been  deferred  and  are  being  recognized  on  a  straight-line  basis  over  the  expected  period  of
performance of the research and development services. During the three month period ended March 31, 2013, the Company extended the revenue recognition period for the
Joint Development Agreement from the previous recognition period ending in November 2013 to December 2014, due to changes in the estimated timing of completion of
certain research and development activities. This change was made on a prospective basis, and resulted in a reduced periodic amount of revenue recognized in current and
future  periods.  Revenue  from  the  remaining  $8,000,000  of  contingent  milestone  payments,  including  the  $3,000,000  received  from  Valeant  in  March  2011,  will  be
recognized  using  the  Milestone  Method  of  accounting.  Deferred  revenue  was  recorded  as  a  liability  captioned  “Deferred  revenue.”  Revenue  recognized  under  the  Joint
Development Agreement is included in “Note 24. Supplementary Financial Information”, in the line item captioned “Other Revenues”.

(2) Royalty Fees Earned — Valeant’s Sale of Advanced Form SOLODYN® (Brand) Product. Under the Joint Development Agreement, the Company granted Valeant a license
for  the  advanced  form  of  the  SOLODYN®  product,  with  the  Company  receiving  royalty  fee  income  under  such  license  for  a  period  ending  eight  years  after  the  first
commercial sale of the advanced form SOLODYN® product. Commercial sales of the new SOLODYN® product, if any, are expected to commence upon FDA approval of
Valeant’s NDA. The royalty fee income, if any, from the new SOLODYN® product, will be recognized by the Company as current period revenue when earned.

(3) Accounting for Sales of the Company’s Four Generic Dermatology Products. Upon FDA approval of the Company’s ANDA for each of the four generic products covered
by the Joint Development Agreement, the Company will have the right (but not the obligation) to begin manufacture and sale of its four generic dermatology products. The
Company  sells  its  manufactured  generic  products  to  all  Impax  Generics  division  customers  in  the  ordinary  course  of  business  through  its  Impax  Generics  Product  sales
channel.  The  Company  accounts  for  the  sale,  if  any,  of  the  generic  products  covered  by  the  Joint  Development  Agreement  as  current  period  revenue  according  to  the
Company’s revenue recognition policy applicable to its Impax Generics products. To the extent the Company sells any of the four generic dermatology products covered by
the Joint Development Agreement, the Company pays Valeant a gross profit share, with such profit share payments accounted for as a current period cost of revenues in the
consolidated statement of operations .

Development and Co-Promotion Agreement with Endo Pharmaceuticals Inc.

In June 2010, the Company and Endo Pharmaceuticals, Inc. ("Endo") entered into a Development and Co-Promotion Agreement (“Endo Agreement”) under which the Company
and  Endo  agreed  to  collaborate  in  the  development and  commercialization  of  a  next-generation  advanced  form  of  the  Company’s lead  branded  product  candidate  ("Endo  Agreement
Product"). The Endo Agreement was terminated upon mutual agreement by the parties effective December 23, 2015. Under the provisions of the Endo Agreement, in June 2010, Endo
paid to the Company a $10,000,000 upfront payment. Prior to termination of the agreement, the Company also had the potential to receive up to an additional $30 million of contingent
milestone payments.

Prior to the termination of the Endo Agreement, the Company had recognized the $10 million upfront payment as revenue on a straight-line basis over a period of 112 months,
which was the estimated expected period of performance of research and development activities under the Endo Agreement, commencing with the June 2010 effective date of the Endo
Agreement and ending in September 2019, the estimated date of FDA approval of the Company's NDA for the Endo Agreement Product. The FDA approval of the Endo Agreement
Product  NDA  represented  the  end  of  the  Company’s  expected  period  of  performance,  as  the  Company  would  have  had  no  further  contractual  obligation  to  perform  research  and
development activities under the Endo Agreement, and therefore the earnings process would have been completed on such date. Deferred revenue under the Endo Agreement was $0 and
$4,310,000 as of December 31, 2015 and 2014, respectively. Revenue recognized under the Endo Agreement was reported in “Note 24. Supplementary Financial Information” in the line
item captioned “Other Revenues”.

F-45

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The  Company  and  Endo  also  entered  into  a  Settlement  and  License  Agreement  in  June  2010  (the  “Endo  Settlement  Agreement”)  pursuant  to  which  Endo  agreed  to  make  a
payment  to  the  Company  should  prescription  sales  of  Opana  ® ER  (as  defined  in  the  Endo  Settlement  Agreement)  fall  below  a  predetermined  contractual  threshold  in  the  quarter
immediately prior to the Company launching a generic version of Opana ® ER. As a result of the Company’s launch of its generic version of Opana ER in January 2013 and Endo’s
prescription sales of Opana ER during the fourth quarter of 2012, the Company recorded a $102,049,000 settlement gain during the three month period ended March 31, 2013, which is
included in “Other Income” in the consolidated statement of operations. Payment of the $102,049,000 settlement was received from Endo in April 2013.

Distribution, License, Development and Supply Agreement with AstraZeneca UK Limited

In January 2012, the Company entered into the AZ Agreement with AstraZeneca. Under the terms of the AZ Agreement, AstraZeneca granted to the Company an exclusive
license to commercialize the tablet, orally disintegrating tablet and nasal spray formulations of Zomig® (zolmitriptan) products for the treatment of migraine headaches in the United
States and in certain U.S. territories, except during an initial transition period when AstraZeneca fulfilled all orders of Zomig® products on the Company’s behalf and AstraZeneca paid
to  the  Company  the  gross  profit  on  such  Zomig®  products.  The  Company  is  obligated  to  fulfill  certain  minimum  requirements  with  respect  to  the  promotion  of  currently  approved
Zomig®  products  as  well  as  other  dosage  strengths  of  such  products  approved  by  the  FDA  in  the  future.  The  Company  may,  but  has  no  obligation  to,  develop  and  commercialize
additional products containing zolmitriptan and additional indications for Zomig®, subject to certain restrictions as set forth in the AZ Agreement. The Company will be responsible for
conducting  clinical  studies  and  preparing  regulatory  filings  related  to  the  development  of  any  such  additional  products  and  would  bear  all  related  costs.  During  the  term  of  the  AZ
Agreement,  AstraZeneca  will  continue  to  be  the  holder  of  the  NDA  for  existing  Zomig®  products,  as  well  as  any  future  dosage  strengths  thereof  approved  by  the  FDA, and  will  be
responsible for certain regulatory and quality-related activities for such Zomig® products. AstraZeneca will manufacture and supply Zomig® products to the Company and the Company
will purchase its requirements of Zomig® products from AstraZeneca until a date determined in the AZ Agreement. Thereafter, AstraZeneca may terminate its supply obligations upon
certain advance notice to the Company, in which case the Company would have the right to manufacture or have manufactured its own requirements for the applicable Zomig® product.

Under the terms  of the AZ Agreement,  AstraZeneca  was required  to make  payments  to the  Company representing  100% of the  gross profit  on sales  of AstraZeneca-labeled
Zomig® products during the specified transition period. The Company received transition payments from AstraZeneca aggregating $43,564,000 during 2012. Beginning in January 2013,
the Company was obligated to pay AstraZeneca tiered royalties on net sales of branded Zomig® products, depending on brand exclusivity and subject to customary reductions and other
terms  and  conditions  set  forth  in  the  AZ  Agreement.  The  Company  is  also  obligated  to  pay  AstraZeneca  royalties  after  a  certain  specified  date  based  on  gross  profit  from  sales  of
authorized generic versions of the Zomig® products subject to certain terms and conditions set forth in the AZ Agreement. In May 2013, the Company’s exclusivity period for branded
Zomig® tablets and orally disintegrating tablets expired and the Company launched authorized generic versions of those products in the United States. The Company owed a royalty
payable to AstraZeneca of $16,848,000, $14,262,000 and $36,113,000 for the years ended December 31, 2015, 2014 and 2013, respectively, with a corresponding charge included in the

22. LEGAL AND REGULATORY MATTERS

Patent Litigation

There is substantial litigation in the pharmaceutical, biological, and biotechnology industries with respect to the manufacture, use, and sale of new products which are the subject of
conflicting patent and intellectual property claims. One or more patents often cover the brand name products for which the Company is developing generic versions and the Company
typically has patent rights covering the Company’s branded products.

Under federal law, when a drug developer files an ANDA for a generic drug seeking approval before expiration of a patent, which has been listed with the FDA as covering the
brand name product, the developer must certify its product will not infringe the listed patent(s) and/or the listed patent is invalid or unenforceable (commonly referred to as a “Paragraph
IV” certification). Notices of such certification must be provided to the patent holder, who may file a suit for patent infringement within 45 days of the patent holder’s receipt of such
notice. If the patent holder files suit within the 45 day period, the FDA can review and approve the ANDA, but is prevented from granting final marketing approval of the product until a
final judgment in the action has been rendered in favor of the generic drug developer, or 30 months from the date the notice was received, whichever is sooner. The Company’s generic
products division is typically subject to patent infringement litigation brought by branded pharmaceutical manufacturers in connection with the Company’s Paragraph IV certifications
seeking an order delaying the approval of the Company’s ANDA until expiration of the patent(s) at issue in the litigation. Likewise, the Company’s branded products division is currently
involved  in  patent  infringement  litigation  against  generic  drug  manufacturers  who  have  filed  Paragraph  IV  certifications  to  market  their  generic  drugs  prior  to  expiration  of  the
Company’s patents at issue in the litigation.  

The uncertainties inherent in patent litigation make the outcome of such litigation difficult to predict. For the Company’s generic products division, the potential consequences in
the event of an unfavorable outcome in such litigation include delaying launch of its generic products until patent expiration. If the Company were to launch its generic product prior to
successful resolution of a patent litigation, the Company could be liable for potential damages measured by the profits lost by the branded product manufacturer rather than the profits
earned  by  the  Company  if  we  are  found  to  infringe  a  valid,  enforceable  patent.    For  the  Company’s  branded  products  division,  an  unfavorable  outcome  may  significantly  accelerate
generic competition ahead of expiration of the patents covering the Company’s branded products. All such litigation typically involves significant expense.

The  Company  is  generally  responsible  for  all  of  the  patent  litigation  fees  and  costs  associated  with  current  and  future  products  not  covered  by  its  alliance  and  collaboration
agreements. The Company has agreed to share legal expenses with respect to third-party and Company products under the terms of certain of the alliance and collaboration agreements.
The Company records the costs of patent litigation as expense in the period when incurred for products it has developed, as well as for products which are the subject of an alliance or
collaboration agreement with a third-party.

Although the outcome and costs of the asserted and unasserted claims is difficult to predict, the Company does not currently expect the ultimate liability, if any, for such matters to

have a material adverse effect on its business, financial condition, results of operations, or cash flows.  

Patent Infringement Litigation

Endo Pharmaceuticals Inc. and Grunenthal GmbH v. Impax Laboratories, Inc. and ThoRx Laboratories, Inc. (Oxymorphone hydrochloride); Endo Pharmaceuticals Inc. and

Grunenthal GmbH v. Impax Laboratories, Inc. (Oxymorphone hydrochloride)

In  November  2012,  Endo  Pharmaceuticals,  Inc.  and  Grunenthal  GmbH  (collectively,  “Endo”)  filed  suit  against  ThoRx  Laboratories,  Inc.,  a  wholly  owned  subsidiary  of  the
Company (“ThoRx”), and the Company in the U.S. District Court for the Southern District of New York alleging patent infringement based on the filing of ThoRx’s ANDA relating to
Oxymorphone hydrochloride, Extended Release tablets, 5, 7.5, 10, 15, 20, 30 and 40 mg, generic to Opana ER®. In January 2013, Endo filed a separate suit against the Company in the
U.S.  District  Court  for  the  Southern  District  of  New  York  alleging  patent  infringement  based  on  the  filing  of  the  Company’s  ANDA  relating  to  the  same  products.  ThoRx  and  the
Company filed an answer and counterclaims to the November 2012 suit and the Company filed an answer and counterclaims with respect to the January 2013 suit. A bench trial was
completed in April 2015. In August 2015, the Court entered judgment that the products described in the Company’s and ThoRx’s ANDAs would, if marketed, infringe certain claims of
the patents asserted by Endo. The Court also found that the asserted claims of patents owned by Endo were not invalid, but that the asserted claims of patents owned by Grunenthal were
invalid. As a result, the Court enjoined the Company and ThoRx from marketing their products until expiration of the Endo patents in 2023. Endo filed post-trial motions to correct and
amend the judgment, which are currently pending. All parties have filed notices of appeal with respect to the Court's judgment. The appeals are deactivated until resolution of the post-
trial motions.

In November 2014, Endo Pharmaceuticals  Inc. and Mallinckrodt  LLC filed suit against the Company in the U.S. District Court for the District  of Delaware making additional
allegations of patent infringement based on the filing of the Company’s Oxymorphone hydrochloride ANDA described above. Also in November 2014, Endo and Mallinckrodt filed a
separate  suit  in  the  U.S. District  Court  for  the  District  of  Delaware  making  additional  allegations  of  patent  infringement  based  on  the  filing  of  ThoRx’s  Oxymorphone  hydrochloride
ANDA described above. ThoRx and the Company filed an answer and counterclaim to those suits in which they are named as a defendant. ThoRx and the Company filed a motion to stay
the litigation, which is pending.

Securities and Derivative Class Actions

On March 7, 2013 and April 8, 2013, two class action complaints were filed against the Company and certain current and former officers and directors of the Company in the

complaint on November 14, 2013. On April 18, 2014, the Court denied the Company’s motion to dismiss. On September 22, 2014, the Company, together with certain current and former
officers and directors of the Company, agreed to settle this consolidated securities class action, without any admission or concession of wrongdoing or liability by the Company or the
other defendants. Pursuant to the settlement, the Company paid $8.0 million for a full and complete release of all claims that were or could have been asserted against the Company or

The Company did not take any charges for the settlement as the settlement amount was paid for and covered by the Company’s insurance policies. The settlement did not resolve the
related shareholder derivative litigations discussed below.

  On March  19, 2013, Virender  Singh, derivatively  on  behalf  of  the  Company,  filed  a  state  court  action  against  certain  current  and  former  officers  and  directors  for  breach  of
fiduciary duty and unjust enrichment  in the Superior Court of the State of California County of Santa Clara, asserting similar allegations  as those in the Securities Class Actions. On
November 6, 2014, plaintiff Singh filed a First Amended Complaint, adding allegations similar to those in the Aruliah Class Action (as described below). The parties have agreed to a
settlement in this matter and the court granted final approval of the settlement on October 13, 2015.

On September  24, 2014, Nicholas  Karant,  derivatively  on  behalf  of the  Company,  filed  an  action  against  certain  current  and  former  officers  and  directors  in  the  United  States
District Court for the Northern District of California, asserting similar allegations as those by Virender Singh. On June 25, 2015, the court dismissed Mr. Karant’s complaint without
prejudice.

On August 13, 2014, a class action complaint was filed against the Company and certain current and former officers and directors of the Company in the United States District
Court  for  the  Northern  District  of  California  by  Linus  Aruliah,  individually  and  on  behalf  of  all  others  similarly  situated  (“Aruliah  Class  Action”).  The  complaint  alleged  that  the
Company and those named officers and directors violated the federal securities laws by making materially false and misleading statements and/or failed to disclose material adverse facts
to the public in connection with manufacturing deficiencies at the Company’s Taiwan manufacturing facility, including but not limited to the impact the deficiencies would have on the
Company’s ability to gain approval from the FDA for the Company’s then branded product candidate, Rytary® (which was subsequently approved by the FDA on January 7, 2015). On
January 13, 2015, the Company, together with certain current and former officers and directors of the Company, agreed to settle this securities class action, without any admission or
concession of wrongdoing or liability by the Company or the other defendants. Pursuant to the settlement, the Company paid $4.75 million for a full and complete release of all claims
that were or could have been asserted against the Company or other defendants in this action. On June 22, 2015, the Court granted preliminary approval of the settlement. On December
21,  2015,  the  Court  granted  final  approval  of  the  settlement.  The  Company  did  not  take  any  charges  for  the  settlement  as  the  settlement  amount  will  be  paid  for  and  covered  by  the
Company’s insurance policies.

On September 22, 2014, Randall Wickey, derivatively on behalf of the Company, filed an action against certain current and former officers and directors of the Company in the
United States District Court for the Northern District of California, alleging breaches of fiduciary duty in connection with the Company’s response to various FDA notices and warnings
regarding problems in the manufacturing and quality control processes at the Company’s Hayward, California and Taiwan manufacturing facilities. On November 10, 2014, International
Union of Operating Engineers Local 478, derivatively on behalf of the Company, filed an action against certain current and former officers and directors of the Company in the United
States District Court for the Northern District of California, asserting similar allegations as those by Randall Wickey. These two derivative actions were consolidated on February 5, 2015
and a consolidated complaint was filed on February 20, 2015. On October 6, 2015, the court dismissed the consolidated complaint with prejudice.

Attorney General of the State of Connecticut Interrogatories and Subpoena Duces Tecum

On  July  14,  2014,  the  Company  received  a  subpoena  and  interrogatories  (the  “Subpoena”)  from  the  State  of  Connecticut  Attorney  General  (“Connecticut  AG”)  concerning  its
investigation  into  sales  of  the  Company’s  generic  product,  digoxin.  According  to  the  Connecticut  AG,  the  investigation  is  to  determine  whether  anyone  engaged  in  a  contract,
combination  or  conspiracy  in  restraint  of  trade  or  commerce  which  has  the  effect  of  (i)  fixing,  controlling  or  maintaining  prices  or  (ii)  allocating  or  dividing  customers  or  territories
relating to the sale of digoxin in violation of Connecticut state antitrust law. The Company intends to cooperate with the Connecticut AG in producing documents and information in
response to the Subpoena. To the knowledge of the Company, no proceedings by the Connecticut AG have been initiated against the Company at this time, however no assurance can be
given as to the timing or outcome of this investigation.

AWP Litigation

On December 30, 2015, Plumbers’ Local Union No. 690 Health Plan and others similarly situated filed a class action against several generic drug manufacturers, including the
Company, in the Court of Common Pleas of Philadelphia County, First Judicial District of Pennsylvania, Civil Trial Division, alleging that the Company and others violated the law,
including the Pennsylvania Unfair Trade Practices and Consumer Protection law, by inflating the Average Wholesale Price (“AWP”) of certain generic drugs.

On February 5, 2016, Delaware Valley Health Care Coalition filed suit asserting similar allegations against the same defendants in the same court.

23. SEGMENT INFORMATION

The Company has two reportable segments, Impax Generics and Impax Specialty Pharma. Impax Generics develops, manufactures, sells, and distributes generic pharmaceutical
products, primarily through the following sales channels: the Impax Generics sales channel for sales of generic prescription products directly to wholesalers, large retail drug chains, and
others; the Private Label Product sales channel for generic over-the-counter and prescription products sold to unrelated third-party customers who, in turn, sell the products under their
own label; the Rx Partner sales channel for generic prescription products sold through unrelated third-party pharmaceutical entities under their own label pursuant to alliance agreements;
and  the  OTC  Partner  sales  channel  for  over-the-counter  products  sold  through  unrelated  third-party  pharmaceutical  entities  under  their  own  labels  pursuant  to  alliance  and  supply
agreements.  Revenues  from  the  “Impax  Generics”  sales  channel  and  the  “Private  Label”  sales  channel  are  reported  under  the  caption  “Impax  Generics  sales,  net”  in  “Note  24.
Supplementary Financial Information.” The Company also generates revenue in Impax Generics from research and development services provided under a joint development agreement
with another unrelated third-party pharmaceutical company, and reports such revenue under the caption “Other Revenues” revenue in “Note 24. Supplementary Financial Information.”
Revenues from the “OTC Partner” sales channel are also reported under the caption “Other Revenues” in “Note 24. Supplementary Financial Information.”

Impax Specialty Pharma is engaged in the development, sale and distribution of proprietary brand pharmaceutical products that the Company believes represent improvements to
already-approved pharmaceutical products addressing central nervous system (“CNS”) disorders and other select specialty segments. Impax Specialty Pharma currently has one internally
developed  branded  pharmaceutical  product,  Rytary®  (IPX066),  an  extended  release  oral  capsule  formulation  of  carbidopa-levodopa  for  the  treatment  of  Parkinson’s  disease,  post-
encephalitic  parkinsonism, and parkinsonism that may follow carbon monoxide intoxication and/or manganese intoxication, which was approved by the FDA on January 7, 2015 and
which the Company launched in April 2015. In November 2015, the European Commission granted marketing authorization for NUMIENT™ (IPX066) (referred to as Rytary® in the
United States). The review of the NUMIENT™ application was conducted under the centralized licensing procedure as a therapeutic innovation, and authorization is applicable in all 28
member states of the European Union, as well as Iceland, Liechtenstein and Norway. Impax Specialty Pharma is also engaged in the sale and distribution of four other branded products
including Zomig® (zolmitriptan) products, indicated for the treatment of migraine headaches, under the terms of the AZ Agreement with AstraZeneca in the United States and in certain
U.S.  territories,  and  Albenza®,  indicated  for  the  treatment  of  tapeworm  infections.  Revenues  from  Impax-labeled  branded  products  are  reported  under  the  caption  “Impax  Specialty
Pharma  sales,  net”  in  “Note  24.  Supplementary  Financial  Information.”  Finally,  the  Company  generates  revenue  in  Impax  Specialty  Pharma  from  research  and  development  services
provided under a development and license agreement with another unrelated third-party pharmaceutical company, and reports such revenue under the caption “Other Revenues” in “Note
24. Supplementary Financial Information.” Impax Specialty Pharma also has a number of product candidates that are in varying stages of development.

The Company’s chief operating decision maker evaluates the financial performance of the Company’s segments based upon segment income (loss) before income taxes. Items
below income (loss) from operations are not reported by segment, since they are excluded from the measure of segment profitability reviewed by the Company’s chief operating decision
maker. Additionally, general and administrative expenses, certain selling expenses, certain litigation settlements, and non-operating income and expenses are included in “Corporate and
Other.” The Company does not report balance sheet information by segment since it is not reviewed by the Company’s chief operating decision maker. The accounting policies for the
Company’s segments are the same as those described above in the discussion of "Revenue Recognition" and in “Note 4. Summary of Significant Accounting Policies.” The Company has
no inter-segment revenue.

Our report dated February 22, 2016, on the effectiveness of internal control over financial reporting as of December 31, 2015, contains an explanatory paragraph that states that the scope
of  management’s  assessment  of  their  effectiveness  of  internal  control  over  financial  reporting  as  of  December  31,  2015  included  Impax  Laboratories,  Inc.’s  consolidated  operations
except for the operations of Tower Holdings, Inc. and Lineage Therapeutics Inc., which Impax Laboratories, Inc. acquired in March 2015. Tower Holdings, Inc. and Lineage Therapeutics
Inc. represented 2% and 14% of Impax Laboratories, Inc. and subsidiaries’ consolidated assets and consolidated revenues as of and for the year ended December 31, 2015. Our audit of
internal  control  over  financial  reporting  of  Impax  Laboratories,  Inc.  also  excluded  an  evaluation  of  the  internal  control  over  financial  reporting  of  Tower  Holdings,  Inc.  and  Lineage
Therapeutics Inc.
