Strategic Report

The Directors present their Strategic Report for the Group covering 
the 15-month financial period ended 31 December 2018.

Our Marketed Products: Epidiolex

Strategy, Objectives and Business Model

Overview
We are a biopharmaceutical company focused on discovering, 
developing and commercialising novel therapeutics from our 
proprietary cannabinoid product platform in a broad range of 
disease areas. In our 20 years of operations, we have established a 
world-leading position in the development of plant-derived 
cannabinoid therapeutics through our proven drug discovery and 
development processes, our intellectual property portfolio and 
regulatory and manufacturing expertise. Our lead cannabinoid 
product is Epidiolex® oral solution, a pharmaceutical formulation 
of cannabidiol (“CBD”), for which we retain global commercial 
rights. Epidiolex was approved by the Food and Drug 
Administration (“FDA”) on 25 June 2018 for the treatment of 
seizures associated with Lennox-Gastaut syndrome, or LGS, or 
Dravet syndrome, in patients two years of age and older. LGS and 
Dravet syndrome are severe childhood-onset, drug-resistant 
epilepsy syndromes. On 28 September 2018, the Drug 
Enforcement Agency (“DEA”) placed Epidiolex in Schedule V, the 
lowest restriction classification. Epidiolex became commercially 
available in the US on 1 November 2018. 

In Europe, we submitted an application for Epidiolex to the 
European Medicines Agency’s, or EMA’s, Committee for Medical 
Products for Human Use (“CHMP”) in December 2017, and we 
expect an opinion from the CHMP on the application in the 
second quarter of 2019. We have received Orphan Drug 
Designation from the FDA for Epidiolex for LGS, Dravet 
syndrome and tuberous sclerosis complex (“TSC”). We also 
received Orphan Designation from the EMA’s Committee for 
Orphan Medical Products (“COMP”) for Epidiolex for Dravet 
syndrome, LGS, and TSC. We continue to develop Epidiolex for 
additional indications, including the treatment of seizures 
associated with TSC and plan to commence a pivotal trial in the 
treatment of Rett syndrome.

Previously, we developed the world’s first plant-derived 
cannabinoid prescription drug, Sativex® (nabiximols), which is 
approved for the treatment of spasticity due to multiple sclerosis 
in numerous countries outside the US. In the US, we met with the 
FDA in December 2018 to discuss the optimal regulatory 
pathway for US approval of Sativex and are now in the process of 
planning a pivotal Phase 3 clinical trial, which we expect to start 
in the fourth quarter of 2019.

We have a deep pipeline of additional cannabinoid product 
candidates focusing primarily on orphan childhood-onset 
neurologic conditions and oncology. Our pipeline includes 
research in autism spectrum disorder (“ASD”) and Rett syndrome 
using both CBD and cannabidivarin (“CBDV”). We reported 
positive Phase 2 data for our CBD:THC product in the treatment 
of glioblastoma multiforme. We have also reported positive Phase 
2 data in schizophrenia. In addition, we have received Orphan 
Drug Designation and Fast Track Designation from the FDA for 
intravenous CBD for the treatment of Neonatal Hypoxic Ischemic 
Encephalopathy (“NHIE”), for which a Phase 1 trial has been 
completed.

Epidiolex in the United States
We launched Epidiolex on 1 November 2018 in the US market 
after FDA approval for the treatment of seizures associated with 
LGS or Dravet syndrome in patients two years of age and older. 
The FDA confirmed orphan drug exclusivity for Epidiolex and 
granted us a rare paediatric disease voucher. Following the 
approval, DEA placed Epidiolex in Schedule V.

We have reported positive results from two LGS Phase 3 pivotal 
trials, both achieving the primary endpoint of a median reduction 
in monthly drop seizures compared with placebo. We have also 
reported positive results from two Phase 3 pivotal trials in Dravet 
syndrome. Epidiolex demonstrated an acceptable safety profile in 
these Phase 3 pivotal trials. The Company’s development 
programme represents the only well-controlled clinical evaluation 
of a cannabinoid medication for patients with LGS and Dravet 
syndrome.

LGS is a type of epilepsy with multiple types of seizures, 
particularly tonic (stiffening) and atonic (drop) seizures. The 
estimated prevalence of LGS is between 3% and 4% of childhood 
epilepsy cases. LGS affects between 14,500 to 18,500 children 
under the age of 18 years in the US and over 30,000 children and 
adults in the US. Eighty percent of children with LGS continue to 
experience seizures, psychiatric, intellectual and behavioural 
deficits in adulthood. Seizures due to LGS are hard to control and 
generally require life-long treatment.

Dravet syndrome is a severe infantile-onset, genetic, drug-
resistant epilepsy syndrome with a distinctive but complex 
electroclinical presentation. Onset of Dravet syndrome occurs 
during the first year of life with clonic seizures (jerking) and 
tonic-clonic (convulsive) seizures in previously healthy and 
developmentally normal infants. Symptoms peak at about five 
months of age, and the latest onset beginning by 15 months of 
age. Other seizures develop between one and four years of age 
such as prolonged focal dyscognitive seizures and brief absence 
seizures, and duration of these seizures decreases during this 
period, but their frequency increases. Prognosis is poor, with 
death occurring in approximately 14% of children. Patients 
develop intellectual disability and life-long ongoing seizures. 
Intellectual impairment varies from severe (50% of patients), to 
moderate (25% of patients), to mild (25% of patients). Patients 
rarely return to normal intellect.

Our US subsidiary, Greenwich Biosciences, markets Epidiolex 
through an experienced commercial organisation consisting of 
sales, medical affairs, marketing, and market access/payer teams. 
Our medical affairs organisation has been in place for over two 
years and includes 15 Medical Science Liaisons. Our US 
marketing plan includes a combination of community neurology/
epilepsy meetings, patient advocacy events, an extensive 
programme for US clinicians to share their Epidiolex experiences 
and a media-based awareness programme.

GW Pharmaceuticals plc | Annual Report and Accounts 2018Strategic Report continued

We manufacture Epidiolex through utilisation of in-house and 
external third-party facilities for various steps in the production 
process. We have expanded various parts of the production 
process both in-house and with external third parties in readiness 
for commercial launch. As part of the New Drug Application 
(“NDA”) review, the FDA pre-approval inspections of our 
manufacturing facilities did not result in any Form 483 
observations. We are continuing to expand our Epidiolex 
manufacturing capacity in anticipation of post-US launch and 
projected demand in Europe and elsewhere.

Epidiolex in Europe
In Europe, we submitted a marketing authorisation application in 
December 2017 for both the Dravet syndrome and LGS indications. 
In late November 2018, during the later stages of this review, the 
second successful Phase 3 pivotal study in Dravet syndrome was 
completed and the Company agreed with the regulatory authority 
to add this data to the application. Fully integrating this data, 
along with some necessary administrative Brexit-related changes, 
now results in an expected EMA/CHMP opinion in the second 
quarter of 2019. GW has recently initiated an Early Access 
Programme in the five largest European countries in Europe, 
enabling patients with the most immediate need to gain access.

We continue to make good progress for the commercialisation of 
Epidiolex in Europe and are planning initial launches in the five 
major European markets in 2019. Our commercial leadership team 
is fully recruited and in place. This experienced team, which 
includes several epilepsy disease experts, is focused on progressing 
the necessary pricing and reimbursement, medical and pre-
commercial activities required to deliver a successful European 
launch. In particular, significant progress is being made on 
building the local country organisations in the five major European 
markets. This first wave of local recruitment is very much focused 
on leadership and medical staff. Medical affairs activities are 
progressing well with national advisory boards now completed in 
all the major markets and significant presence and data exposure at 
key European and National Congresses.

Epidiolex Follow-On Target Indication: TSC
TSC is a genetic disorder that causes non-malignant tumours to 
form in many different organs, primarily in the brain, eyes, heart, 
kidney, skin and lungs. According to the Tuberous Sclerosis 
Alliance, TSC is estimated to affect approximately 50,000 
patients in the US. The most common symptom of TSC is 
epilepsy, which occurs in 75 – 90% of patients, about 70% of 
whom experience seizure onset in their first year of life. 
Approximately 60% of these TSC patients (or approximately 
25,000 of patients in the US) have treatment-resistant seizures.

We are progressing a Phase 3 trial of Epidiolex in patients with 
TSC. This 210-person trial, which is fully recruited, is a 16-week 
comparison of Epidiolex versus placebo to assess the safety and 
efficacy of Epidiolex as an adjunctive anti-epileptic treatment. 
Data from this trial is expected in the first half of 2019. Subject to 
positive results, we expect to submit a supplemental NDA for 
Epidiolex in TSC in the second half of 2019.

Epidiolex Follow-On Target Indication: Rett Syndrome
Rett syndrome (“RTT”) is a rare, non-inherited, X-linked 
neurodevelopmental disorder affecting approximately 1 in 10,000 
to 15,000 live female births. There are no approved treatments for 

RTT. The management options target specific symptoms and are 
not without undesirable side effects. As such, there is currently a 
high unmet medical need. Data from animal models suggests 
CBD may be able to improve deficits in cognition, language, 
social behaviour and motor function, as well as having the 
potential to modulate the cellular mechanisms thought to be 
involved in the neurobehavioural deficits present in RTT.

A Phase 3 trial of Epidiolex in patients with RTT is expected to 
start in the second quarter of 2019. It is an international multi-
centre, randomised, double-blind, placebo-controlled study to 
investigate safety and efficacy.

Epidiolex Formulation Life Cycle Management
In addition to the Epidiolex formulation, we continue to develop 
additional formulations of CBD as part of its life cycle 
management plan. We are developing a capsule to provide more 
convenient administration, particularly for adults and older 
children across our target indications. We are also developing an 
improved oral solution.

Our Marketed Products: Sativex

Sativex is an oromucosal spray of a formulated extract of the 
cannabis sativa plant. We developed Sativex to be administered 
as an oromucosal spray, whereby the active ingredients are 
absorbed in the lining of the mouth, either under the tongue or 
inside the cheek. At this time, we have received regulatory 
approval for Sativex in numerous countries outside the US.

Sativex in the US
In December 2017, we terminated our license agreement with 
Otsuka Pharmaceutical Co., Ltd., in relation to Sativex in the US 
and we have reacquired full ownership of the development and 
commercialisation rights to the product in the US. In the US, 
we met with the FDA in December 2018 to discuss the optimal 
regulatory pathway for US approval of Sativex and are now in 
the process of planning a pivotal Phase 3 clinical trial, which 
we expect to commence in the fourth quarter of 2019.

Beyond an initial target US indication of MS spasticity, we believe 
that Sativex has significant additional market potential. We have 
completed over 10 placebo-controlled trials and believe there is 
the potential for future development of multiple indications.

Sativex in Europe
To support the development and commercialisation of Sativex in 
Europe, we have license and development agreements with the 
following major pharmaceutical companies: Almirall S.A., or 
Almirall, in Europe (excluding the UK) and Mexico; Bayer 
HealthCare AG, or Bayer, in the UK and Canada; Ipsen Biopharm 
Ltd, or Ipsen, in Latin America (excluding Mexico and the 
Islands of the Caribbean); and Neopharm Group, or Neopharm, 
in Israel. These agreements provide our collaborators with the 
sole right to commercialise Sativex in exclusive territories for all 
indications.

Sativex Intellectual Property
Our strategy is to seek and obtain patents related to Sativex 
across all major pharmaceutical markets around the world. In the 
US, our patents (and our pending applications if they issue) 
relating to Sativex would expire on various dates between 2021 

02

GW Pharmaceuticals plc | Annual Report and Accounts 2018and 2029, excluding possible patent term extensions. We have 
at least seven different patent families containing one or more 
pending and/or issued patents directed to the Sativex 
formulation, the extracts from which Sativex is composed, the 
extraction technique used to produce the extracts and the 
therapeutic use of Sativex.

Proprietary Cannabinoid Product Platform

We have established a world-leading position in cannabinoid 
therapeutics through our proven proprietary cannabinoid 
product platform. Our platform consists of a continually evolving 
library of internally generated novel cannabis plant types that 
produce selected cannabinoids, discovery of novel cannabinoid 
pharmacology through our network of world-leading scientists, 
a global intellectual property portfolio, in-house formulation, 
processing and manufacturing capabilities, and development and 
regulatory expertise. We further believe that we are in a unique 
position to develop and manufacture plant-derived cannabinoid 
formulations worldwide at sufficient quality, uniformity, scale 
and sophistication for the purposes of pharmaceutical 
development and to meet international regulatory requirements.

The cannabis plant is the unique source of more than 70 
structurally related, plant-derived cannabinoids. Although one 
cannabinoid, THC, is known to cause psychoactive effects 
associated with the use of illicit herbal cannabis, none of the 
other cannabinoids are known to share this property. In recent 
decades, there have been major scientific advances that have led 
to the discovery of new plant-derived cannabinoids and a 
cannabinoid receptor system in the human body, or 
endocannabinoid system. We are at the forefront of this new area 

of science, and we believe that our proprietary cannabinoid 
product platform uniquely positions us to discover and develop 
cannabinoids as new therapeutics.

Our proprietary cannabinoid product platform consists of our: 

 > continually evolving library of internally generated novel 

cannabis plant types that produce selected cannabinoids, or 
chemotypes. We can reproduce the selected chemotypes 
through propagation of plant cuttings, or clones, in order to 
ensure that all subsequent plant material is genetically 
uniform. We can also generate seeds of selected chemotypes 
for large-scale production; 

 > in-house extraction, processing methodologies and analytical 
techniques, which yield well-characterised and standardised 
chemotype extracts; 

 > discovery of novel cannabinoid pharmacology through 

conducting pharmacologic evaluation studies in validated 
disease models to determine the most promising potential 
therapeutic areas for each extract;

 > in-house formulation and manufacturing capabilities, 

supplemented by third-party contractors;

 > global in-house development and regulatory expertise; and 
 > intellectual property portfolio, which includes issued and/or 
pending claims directed to plants, plant extracts, extraction 
technology, pharmaceutical formulations, drug delivery and 
the therapeutic uses of cannabinoids, as well as plant variety 
rights, know-how and trade secrets.

With the exception of Sativex, which is subject to licensing 
agreements described above, we retain global commercial rights 
to all of our product pipeline candidates.

GW Pharmaceuticals plc | Annual Report and Accounts 2018Business Strategy

Our goal is to capitalise on our leading position in the field  
of plant-derived cannabinoid therapeutics by pursuing the 
following strategies:

 > Commercialise our lead product candidate Epidiolex in Dravet 

syndrome and LGS in the US and Europe using our own 
commercial organisation, and to identify the optimal 
commercial pathway in other markets around the world.

 > Expand the market opportunity for Epidiolex within the field 

of epilepsy and Rett syndrome.

 > Seek US approval for Sativex, commercialise Sativex in the US 
using our own commercial organisation, and expand the 
Sativex market to new indications.

 > Advance several clinical-stage proprietary cannabinoid 

product candidates to late-stage development. 

 > Leverage our proprietary cannabinoid product platform and 

world-leading position to discover, develop and commercialise 
additional novel first-in-class cannabinoid products. 

 > Further strengthen our lead competitive position. 

Review of the Business
The Group has changed its year-end to 31 December, and this is the 
first set of financial statements adopting the new year-end date. We 
are reporting for the 15-month period ended 31 December 2018.

The Group has also elected to convert its presentational currency 
to US Dollars to be consistent with our external financial reports 
to the United Securities and Exchange Commission, as required 
by our listing on NASDAQ. The Group additionally reassessed 
the functional currency of its Group companies and considered 
that the Group’s top company, GW Pharmaceuticals plc, had a 
functional currency of US Dollars with effect from 1 July 2018.

To enable prior period comparisons, we are also reporting pro 
forma unaudited results for the 12-month period ended 
31 December 2018 and comparatives for the 12-month period 
ended 31 December 2017 (referred to here as 2018 and 2017 
respectively). The unaudited results have been prepared using the 
same accounting policies and procedures as the audited results.

We believe that the presentation of these unaudited results is also 
representative of the performance in the 15-month period to 
31 December 2018. Any deviations from this are explained below.

The below results include the implementation of IFRS 15 Revenue 
from Contracts with Customers during the 15-month period and 
year to 31 December 2018. The results below for the three months 
and year to 31 December 2017 do not include the impact of this 
implementation.

GW Pharmaceuticals plc | Annual Report and Accounts 2018Strategic Report continued

Revenue
Total revenue for the year ended 31 December 2018 was 
$15.4 million, compared to $15.7 million for the year ended 
31 December 2017. The decrease of $0.3 million comprises:

 > An increase of $6.3 million in product sales to $14.8 million 
for the year ended 31 December 2018, compared to $8.5 
million for the year ended 31 December 2017. This was driven 
by:
 – The recording of $4.7 million in Epidiolex product sales 

revenues following the product launch in the United States 
in November 2018.

 – A $1.6 million increase in Sativex product sales revenues to 

$10.1 million due to increased shipments to partners. 
In-market sales volumes sold by GW’s commercial partners 
for the year ended 31 December 2018 were 16% higher than 
the year ended 31 December 2017.

 > A $4.9 million decrease in licence, collaboration and technical 
access fees following the adoption of IFRS 15 in the period. 
This has resulted in the acceleration of all previously-
unrecognised deferred fee income.

 > A $1.8 million decrease in research and development fee 

income to $0.4 million compared to $2.2 million for the year 
ended 31 December 2017. This reflects the continued 
reduction of rechargeable activity associated with our prior 
collaboration with Otsuka, which ended in December 2017.

 > A $0.1 million decrease in development and approval 

milestones.

The explanations above are also representative of the increase of 
$8.9 million to $19.4 million for the 15-month period ended 
31 December 2018 compared to $10.5 million for the year ended 
30 September 2017.

Cost of Sales
Cost of sales for the year ended 31 December 2018 of $6.7 million 
represents an increase of $1.9 million compared to the $4.8 
million recorded in the year ended 31 December 2017. This 
increase reflects the launch of Epidiolex in the United States as 
well as the growth in the volume of Sativex inventory shipped to 
commercial partners in the current period.

Research and Development Expenditure
Total R&D expenditure for the year ended 31 December 2018 of 
$126.3 million decreased by $25.8 million compared to the 
$152.1 million incurred in the year ended 31 December 2017.

The most significant driver for the decrease in R&D expenditure 
is the commencement of capitalisation of Epidiolex inventory 
onto the balance sheet. The Group determined that the successful 
acceptance by the Federal Drug Administration (FDA) for 
Epidiolex in the United States in December 2017 triggered the 
commencement of capitalisation of inventory; prior to this date, 
all high CBD plant material and associated production costs were 
expensed as R&D.

From 1 January 2018 onwards, manufacturing and associated 
production costs were absorbed into inventory and capitalised 
onto the balance sheet, with a full provision against this material. 
This inventory was fully provided for until the point of product 
approval, which occurred in June 2018. The closing Epidiolex 
inventory balance as at 31 December 2018 was $44.4 million.

Sales, General and Administrative Expenses
Sales, general and administrative expenses for the year ended 
31 December 2018 of $164.2 million increased by $95.8 million 
compared to the $68.4 million incurred in the year ended 
31 December 2017. This net increase is due to the launch of 
Epidiolex in the United States in November 2018, which included 
the hiring of an internal salesforce, finalising infrastructure and 
commercialisation processes required for a company marketing 
its own product in the United States for the first time. 
Additionally, the Group continues to hire key business leads and 
positions in Europe ahead of potential launches in 2019.

The explanations above are also representative of the increase of 
$134.4 million to $187.6 million for the 15-month period ended 
31 December 2018 compared to $53.2 million for the year ended 
30 September 2017.

Net Foreign Exchange Gains/(Losses)
Net foreign exchange movements resulted in a $0.8 million gain for 
the year ended 31 December 2018 compared to a $24.5 million loss 
for the year ended 31 December 2017. This foreign exchange gain 
mostly arises from unrealised gains on our US Dollar denominated 
cash deposits upon retranslation at the closing balance sheet 
exchange rate.

Interest Expense
Interest expense of $1.3 million for the year ended 31 December 
2018 increased by $0.1 million compared to the $1.2 million 
recorded for the year ended 31 December 2017. This increase 
reflects an increase in interest paid on leases for manufacturing 
facilities and interest on repayments of the fit-out funding 
previously received.

Interest and Other Income
Interest and other income increased by $6.2 million to $9.5 
million for the year ended 31 December 2018 compared to $3.3 
million for the year ended 31 December 2017. This increase 
reflects the recognition of the Group’s expected R&D large 
company tax credit claim (“RDEC”) in respect of the statutory 
15-month period ended 31 December 2018. Previously the Group 
was eligible to claim R&D tax credits under the Small and 
Medium Enterprise (“SME”), and these were classified within 
Tax Benefit. The additional increase reflects growth in interest 
income earned on the Group’s cash and cash equivalents balance 
throughout the period.

Tax
Our tax benefit decreased by $21.4 million to a $1.7 million charge 
for the year ended 31 December 2018 compared to $19.7 million 
benefit for the year ended 31 December 2017. As noted in “Interest 
and Other Income” above, this previously included the Group’s 
SME R&D tax claim for which the Group is no longer eligible.

The explanation above is also representative of the decrease of 
$31.6 million to a $5.1 million charge for the 15-month period 
ended 31 December 2018 compared to a $26.5 million benefit for 
the year ended 30 September 2017.

GW Pharmaceuticals plc | Annual Report and Accounts 2018Consolidated Balance Sheet
The following information is on an “as reported” basis as noted 
on the Consolidated Income Statement shown on page 40, and 
illustrates the movement from the end of the balance sheet 
periods of 30 September 2017 to 31 December 2018.

Property, plant and equipment
Property, plant and equipment increased by $31.1 million to 
$89.4 million at 31 December 2018 compared to $58.3 million 
at 30 September 2017. This reflects the Group’s continuing 
investment in expansion of our cannabinoid extraction and 
production facilities in the United Kingdom.

Inventories
Total inventories increased by $45.3 million to $51.0 million at 
31 December 2018 compared to $5.7 million at 30 September 
2017. This increase is due to the commercialisation of Epidiolex. 
Effective from 1 January 2018, costs associated with producing 
Epidiolex commercial inventory were capitalised as an asset to 
the balance sheet but fully-provided against. Upon approval from 
the FDA in June 2018, this provision was reversed to the extent 
that the material was supportable by sales forecasts, as the 
uncertainty surrounding the recoverability of this inventory had 
been removed.

Cash and cash equivalents
Total cash and cash equivalents increased by $269.3 million to 
$591.5 million at 31 December 2018 compared to $322.2 million 
at 30 September.

 > Total net cash outflow from operating activities for the 15 

months to 31 December 2018 was $301.4 million, representing 
the operating expenditure of the organisation and 
commercialisation scale-up activities.

 > Total net cash inflow from financing activities was $620.8 

million, representing the completion of two public offerings on 
NASDAQ in December 2017 and October 2018, raising a 
combined total of $622.5 million (net) after expenses.
 > Total cash outflow from investing activities was a net 

$41.4 million, predominantly driven by capital expenditure 
associated with the construction of our manufacturing 
facilities.

Subsequent to the period end date, the Group completed the sale 
of a Rare Pediatric Disease Priority Review Voucher for $105.0 
million. See Note 28 for further details.

Trade and other payables
Total current trade and other payables increased by $19.4 million 
to $63.6 million at 31 December 2018 compared to $44.2 million 
at 30 September 2017. This increase reflects the scale-up of the 
Group’s operations following Epidiolex commercial launch in 
November 2018, and additional organisation costs associated 
with preparation for European commercialisation.

Deferred revenue
Total deferred revenue has decreased to $nil at 31 December 2018 
compared to $8.8 million at 30 September 2017. This is following 
the adoption of IFRS 15 Revenue from Contracts with Customers 
which has resulted in the acceleration of previously unrecognised 
deferred income. More information is presented in Note 2 to the 
financial statements.

Our Key Business Trends

The following information provides a summary of the 
development and performance of the Company’s business during 
the 15-month period and the position of the business as at 
31 December 2018.

We have elected to provide unaudited calendar year figures to 
provide the maximum information to shareholders, and this 
aligns with the Group’s amended accounting reference date of 
31 December.

The Group considers that the primary key performance indicator 
is the progress on the regulatory approval, rescheduling and sales 
volumes of Epidiolex in the US and around the world. The 
progress of regulatory filings and product launches are not easily 
quantifiable, but best represents the Group’s progress during 
2018.

Revenue
Our revenues consist of product sales revenues, R&D fees, 
licence, collaboration and technical access fees and development 
and approval milestone fees. 

The trend analysis below reflects the impact of the adoption of 
IFRS 15 Revenue from Contracts with Customers and assumes 
that revenue accounting under IFRS 15 had been in place since 
1 October 2014. The impact of this removes any license, 
collaboration and technical access fee for the years ended 
31 December 2016, 2017 and 2018.

For the year ended 31 December 2018, we recorded revenues 
of $15.4 million, an increase of $4.6 million or 42% from the 
$10.8 million recorded for the year ended 31 December 2017.

 > In the year to 31 December 2018 we saw the commercial 

launch of Epidiolex, recording revenue of $4.7 million. This is 
the Group’s first own commercial product, and first marketed 
into the United States

 > We recorded Sativex product sales revenue of $10.1 million in 
the year ended 31 December 2018, an increase of $1.6 million 
from the $8.5 million recorded in the year ended 31 December 
2017. This is supported by strong performance in market, 
particularly in Germany. In-market sales made by our 
commercial partners increased by 16%

 > We have seen a continued decline in our R&D fee income to 
$0.4 million compared to $1.8 million for the year ended 
31 December 2017. This reflects the conclusion of rechargeable 
activity associated with our prior collaboration with Otsuka, 
which ended in December 2017.

We see product sales as the key driver for the Group, following 
the launch of Epidiolex in the United States in November 2018.

Number of Countries Sold to In-Market
The Number of Countries Sold to In-Market graph below primarily 
illustrates the in-market commercial sales volumes of Sativex® by 
our commercial marketing partners Bayer in the United Kingdom 
and Canada, Almirall in Europe, Neopharm in Israel and Ipsen in 
South America. This also includes the impact of the launch of 
Epidiolex in the United States from 1 November 2018.

In total, the number of countries sold to in-market grew from 16 
countries at 31 December 2017, to 20 countries at 31 December 
2018. In the period, the first in-market sales were made 
predominantly in South American territories, including Brazil, 
Chile and Colombia via our marketing partner, Ipsen, as well as 
our first launch of Epidiolex into the United States.

As at 31 December 2014, commercial sales were present in 
thirteen territories. In 2015, Almirall launched Sativex in 
Belgium. In 2017 we launched in New Zealand and Australia 
following the return of the rights for Sativex® from Novartis.

We expect the growth of Epidiolex sales markets, subject to 
approval, to be the key driver in this trend for future years.

Total Group Expenditure
As illustrated in the Total Group Expenditure graph below, our 
R&D expenditures have shown a consistent growth trend over 
the last five financial years from $71.3 million in 2014 to $152.1 
million in 2017. This increase reflected the Phase 3 clinical 
research with Epidiolex, progress with other pipeline product 
candidates and scale up of R&D activities associated with our 
growing programmes.

The decline to $126.3 million in 2018, a decrease of 
$25.8 million, is due to the absorption of costs associated with 
inventory previously expensed as R&D which were eligible for 
capitalisation once sufficient certainty of product approval had 
been received from the FDA. Inventory recognition commenced 
from 1 January 2018.

Sales, general and administrative expenditure has increased from 
$9.4 million in 2014, from when all of the Group’s external 
commercial sales were conducted through partners, to $164.2 
million in 2018. The increase of $95.8 million from $68.4 million 
in 2017 to $164.2 million reflects the completion of the full 
commercial organisation in place in the United States to support 
the commercial launch of Epidiolex on 1 November, as well as the 
significant investment in pre-launch activities in Europe.

Since our listing on NASDAQ in May 2013, having taken the 
decision to invest in the development of Epidiolex to treat a 
number of refractory forms of childhood onset epilepsy we have 
consistently recorded operating cash outflows, offset by the 
proceeds of a series of fundraisings, each of which have been 
conducted following the achievement of key product development 
milestones. Our aim has been to ensure that the Group remains 
well funded with sufficient working capital to successfully 
execute our Epidiolex and other pipeline product development 
plans. Consequently, we have completed at least one equity 
fundraising in each of 2014 through to 2018, to help execute this 
strategy.

During 2018 we completed a public offering of 26,220,000 
ordinary shares of the Company on the NASDAQ Global Market, 
raising net proceeds after underwriting discounts and 
commissions of $324.6 million.

We believe that we are suitably well-funded to execute on our US 
Epidiolex launch, prepare for European commercialisation and 
continue our life cycle and clinical development programmes.

Principal Risks and Uncertainties

In common with other pharmaceutical development companies, 
GW faces a number of risks and uncertainties. Internal controls are 
in place to help identify, manage and mitigate these risks. A Risk 
Committee has been established who, based upon input from 
programme directors, functional heads and subject matter experts, 
prepare a risk matrix outlining the status of risks, mitigating controls 
and action plans. This matrix is reviewed by the Board of the 
Company as part of their annual assessment of the principal risks 
and risk management controls.

Further details of risk factors considered by GW for the 15-month 
period ended 31 December 2018 are included on Form 10-KT which 
was filed with the US Securities and Exchange Commission on 
27 February 2019. The risks have been identified as follows:

Marketing and Commercialisation
 > Our prospects are highly dependent on the successful 

commercialisation of Epidiolex.

 > If we do not obtain regulatory approval of Epidiolex for other 

indications in the US, or for any indications in foreign 
jurisdictions, we will not be able to market Epidiolex for other 
indications or in other jurisdictions, which will limit our 
commercial revenues.

 > Our FDA approval subjects us to ongoing obligations and 

continued regulatory review, which may result in significant 
additional expense and, if we do not meet those ongoing 
obligations, we could be subject to significant penalties, 
including market withdrawal and/or civil or criminal penalties.

 > Epidiolex has only been studied in a limited number of 
patients and in limited populations. As we continue our 
commercial launch, Epidiolex will become available to a much 
larger number of patients, and we do not know whether the 
results of Epidiolex use in such larger number of patients will 
be consistent with the results from our clinical trials.

 > We have limited marketing experience, and have only recently 
established our sales force, distribution and reimbursement 
capabilities, and we may not be able to successfully 
commercialise Epidiolex, or any of our product candidates if 
they are approved in the future.

 > Our product candidates, if approved, may be unable to achieve 
the expected market acceptance and, consequently, limit our 
ability to generate revenue from new products.

 > We expect to face intense competition, often from companies 

with greater resources and experience than we have.

 > Product shipment delays could have a material adverse effect 
on our business, results of operations and financial condition.

 > If the price for Epidiolex, Sativex or any future approved 

products decreases or if governmental and other third-party 
payers do not provide adequate coverage and adequate 
reimbursement levels, our revenue and prospects for 
profitability will suffer.

 > Counterfeit versions of our products could harm our business.
 > Our existing collaboration arrangements and any that we may 
enter into in the future may not be successful, which could 
adversely affect our ability to develop and commercialise 
Epidiolex, Sativex and our product candidates.

09

GW Pharmaceuticals plc | Annual Report and Accounts 2018 
 
Strategic Report continued 

Clinical
 > We are dependent on the success of our product candidates, 
some of which may not receive regulatory approval or be 
successfully commercialised.

 > Clinical trials for our product candidates are expensive, 

time-consuming, uncertain and susceptible to change, delay or 
termination. The results of clinical trials are open to differing 
interpretations.

 > Information obtained from expanded access studies may not 
reliably predict the efficacy of our product candidates in 
Company-sponsored clinical trials and may lead to adverse 
events that could limit approval.

 > There is a high rate of failure for drug candidates proceeding 

through clinical trials.

Regulatory and Legislative
 > Epidiolex, Sativex and our product candidates contain 

controlled substances, the use of which may generate public 
controversy.

 > The development of a REMS for Epidiolex or our product 
candidates could cause delays in the approval process and 
would add additional layers of regulatory requirements that 
could impact our ability to commercialise our product 
candidates in the US and reduce their market potential.

 > Controlled substance legislation differs between countries and 
legislation in certain countries may restrict or limit our ability 
to sell Epidiolex, Sativex and our product candidates.

 > Epidiolex is and the product candidates we are developing will 
be subject to US controlled substance laws and regulations and 
failure to comply with these laws and regulations, or the cost 
of compliance with these laws and regulations, may adversely 
affect the results of our business operations, both during 
clinical development and post approval, and our financial 
condition.

 > If one of our product candidates is approved and classified as a 

Schedule II controlled substance, federal law may impose 
additional restrictions on importation for commercial 
purposes.

 > If product liability lawsuits are successfully brought against 

 > The legalisation and use of medical and recreational marijuana 

us, we will incur substantial liabilities and may be required to 
limit the commercialisation of Epidiolex, Sativex and our 
product candidates.

 > Our employees may engage in misconduct or other improper 

activities, including noncompliance with regulatory standards 
and requirements.

 > If we are unable to use net operating loss carry-forwards and 

certain built-in losses to reduce future tax payments, or benefit 
from favourable tax legislation, our business, results of 
operations and financial condition may be adversely affected.
 > We are subject to the UK Bribery Act, the US Foreign Corrupt 
Practices Act and other anti-corruption laws, as well as export 
control laws, customs laws, sanctions laws and other laws 
governing our operations. If we fail to comply with these laws, 
we could be subject to civil or criminal penalties, other 
remedial measures, and legal expenses, which could adversely 
affect our business, results of operations and financial 
condition.

 > Our proprietary information, or that of our customers, 

suppliers and business partners, may be lost or we may suffer 
security breaches.

 > Legislative or regulatory reform of the health care system in 
the US and foreign jurisdictions may affect our ability to 
profitably sell our products, if approved.

 > We expect additional federal and state legislative proposals for 
health care reform, which could limit the prices that can be 
charged for the products we develop and may limit our 
commercial opportunity.

 > Any failure by us to comply with existing regulations could 

harm our reputation and operating results.

in the US and elsewhere may impact our business.

Orphan Drug Designation and Intellectual Property
 > In respect of our product candidates targeting rare indications, 
orphan drug exclusivity may afford limited protection, and if 
another party obtains orphan drug exclusivity for the drugs 
and indications we are targeting, we may be precluded from 
commercialising our product candidates in those indications 
during that period of exclusivity.

 > We may not be able to adequately protect Epidiolex, Sativex, 
our product candidates or our proprietary technology in the 
marketplace.

 > If third parties claim that intellectual property used by us 

infringes upon their intellectual property, our operating profits 
could be adversely affected.

Manufacturing and Technology
 > Problems in our manufacturing process, failure to comply with 
manufacturing regulations or unexpected increases in our 
manufacturing costs could harm our business, results of 
operations and financial condition.

 > We may fail to expand our growing and manufacturing 

capability in time to meet market demand for our products 
and product candidates, and the FDA may refuse to accept 
our facilities or those of our contract manufacturers as being 
suitable for the production of our products and product 
candidates.

 > Product recalls or inventory losses caused by unforeseen 

events, cold chain interruption and testing difficulties may 
adversely affect our operating results and financial condition.

 > We are subject to federal, state and foreign healthcare laws and 

 > Business interruptions could delay us in the process of 

regulations and implementation of or changes to such 
healthcare laws and regulations could adversely affect our 
business and results of operations.

 > If we are found in violation of federal or state “fraud and 

abuse” laws, we may be required to pay a penalty and/or be 
suspended from participation in federal or state health care 
programmes, which may adversely affect our business, 
financial condition and results of operations.

 > Our ability to research, develop and commercialise Epidiolex, 
Sativex and our product candidates is dependent on our ability 
to maintain licenses relating to the cultivation, possession and 
supply of controlled substances.

10

developing our product candidates and could disrupt our 
product sales.

 > Failure of our information technology systems, including 

cybersecurity attacks or other data security incidents, could 
significantly disrupt the operation of our business.

 > Security breaches, loss of data and other disruptions could 
compromise sensitive information related to our business, 
prevent us from accessing critical information or expose us to 
liability, which could adversely affect our business and our 
reputation.

GW Pharmaceuticals plc | Annual Report and Accounts 2018 > We depend on a limited number of suppliers for materials and 
components required to manufacture Epidiolex, Sativex and 
our product candidates. The loss of these suppliers, or their 
failure to supply us on a timely basis, could cause delays in our 
current and future capacity and adversely affect our business.

Safety
 > Serious adverse events or other safety risks could require us to 
abandon development and preclude, delay or limit approval of 
our product candidates, limit the scope of any approved label 
or market acceptance, or cause the recall or loss of marketing 
approval of products that are already marketed.

Staffing
 > If we are unable to effectively train and equip our sales force, 
our ability to successfully commercialise Epidiolex may be 
harmed.

 > We have recently grown our business and will need to further 
increase the size and complexity of our organisation in the 
future, and we may experience difficulties in managing our 
growth and executing our growth strategy.

 > We depend upon our key personnel and our ability to attract 

and retain employees.

Funding and Operational
 > We have significant and increasing liquidity needs and may 

require additional funding.

 > Operating results may vary significantly in future periods.
 > We may acquire other companies which could divert our 

management’s attention, result in additional dilution to our 
shareholders and otherwise disrupt our operations and harm 
our operating results.

 > A significant portion of our cash and cash equivalents are held 

at a small number of banks.

 > The market price of our ADSs may be volatile.
 > Our largest shareholder owns a significant percentage of our 

share capital and voting rights of the Company.

 > Substantial future sales of our ADSs in the public market, or 
the perception that these sales could occur, could cause the 
price of the ADSs to decline.

 > Unlike in prior years, as of 1 October 2018, we are required to 

comply with the domestic reporting regime under the 
Exchange Act and will incur significant legal, accounting and 
other expenses, and our management will be required to 
devote substantial additional time to new compliance 
initiatives and corporate governance matters.

 > US investors may have difficulty enforcing civil liabilities 
against our Company, our Directors or members of senior 
management.

 > The rights of our shareholders may differ from the rights 
typically offered to shareholders of a US corporation.

 > We may be classified as a passive foreign investment company, 
or PFIC, in any taxable year and US holders of our ordinary 
shares could be subject to adverse US federal income tax 
consequences.

Brexit
 > The UK’s vote in favour of withdrawing from the European 
Union (known as “Brexit”) could lead to increased market 
volatility which could adversely impact the market price of our 
ADSs and make it more difficult for us to do business in 
Europe or have other adverse effects on our business.

In response to this situation, the Group established a cross-
functional Brexit Taskforce early in 2018. The Group’s position 
has been to expect the most disruptive impact of Brexit, and 
therefore has pre-emptively moved any EU-dependent 
pharmaceutical product registrations and employment roles to be 
located or duplicated within the European Union.

However, until the Brexit process is concluded by the UK and EU 
parliaments and the impacts of transition to any new arrangement 
between them are known with clarity, it is difficult to anticipate 
the overall potential impact on the Group’s operations and hence 
the final expected costs to be incurred.

Risk in Relation to the Use of Financial Instruments
The Group is exposed to a number of financial risks, including 
credit risk, liquidity risk, market price risk and exchange rate 
risk. It is the Group’s policy that no speculative trading in 
financial instruments shall be undertaken, and as such the Group 
does not enter into contracts for complicated or compound 
financial instruments. Further details are provided in note 21 to 
the financial statements.

Credit Risk
 > The Group’s principal financial assets are cash and short-term 

cash equivalents. Risk is minimised through an investment policy 
restricting the investment of surplus cash to interest-bearing 
deposits principally held with the major UK banking groups and 
with UK subsidiaries of banking groups, and US government 
interest-bearing bonds with acceptable credit ratings.

 > Trade receivables are concentrated in a small number of large 
customers, predominantly across the US and Europe, with 
well-established relationships, where the risk and history of 
default is considered to be low.

Liquidity Risk
 > This risk is minimised by placing surplus funds in a range of 
low-risk cash deposits and short-term liquid investments for 
periods up to 90 days. This portfolio of deposits is managed to 
ensure that a rolling programme of maturity dates is managed 
in accordance with Group expenditure plans in order to 
ensure available liquid cash funds when required.

Market Price Risk
 > Market price risk primarily comprises interest rate exposure 

risk, which is managed by maintaining a rolling programme of 
varying deposit maturity dates, up to a maximum of 90 days, 
on a breakable deposit basis. The majority of funds are 
deposited for terms of less than 90 days. This allows the 
Group to react to rate changes within a reasonable timeframe 
and to mitigate pricing risk accordingly.

Exchange Rate Risk
 > The individual financial statements of each Group Company 

are prepared in the currency of the primary economic 
environment in which it operates (its functional currency). 
For the purpose of the consolidated financial statements, the 
results and financial position of the Group are presented in 
US Dollars.

Exchange rate fluctuations between local currencies and the US 
Dollar create risk in several ways, including the following:

The Group maintains and operates a Code of Conduct and 
Business Ethics called “i-CARE”. This sets out the Group’s 
approach to ensure that our corporate values are maintained 
throughout our global business through five main arms:

 > Integrity
 > Compliance
 > Accountability
 > Respect
 > Ethics

 > weakening of the US Dollar may increase the US Dollar cost of 

overseas R&D expenses and the cost of sourced product 
components outside the US;

 > strengthening of the US Dollar may decrease the value of our 

revenues denominated in other currencies;

 > exchange rates on non-Dollar transactions and cash deposits 

can distort our financial results; and

 > commercial pricing and profit margins are affected by 

currency fluctuations.

This Code applies to all employees of GW companies, who are 
required to comply with this policy.

The Group considers that respecting human rights is a global 
standard of expected conduct for all business enterprises. The 
Group aims to comply with all applicable laws, especially health 
and safety, to prevent abuses of human rights. Regular dialogue is 
held between employees at each of the Group’s sites and senior 
management to ensure that any issues are identified and resolved.

The Group believes that the move to report in US Dollar has 
minimised the reporting risk, as the largest proportion of cash 
and cash equivalents is held in that currency.

During the period the Group had exposure to Pounds Sterling 
(“GBP”), Euros (“€”) and Canadian Dollars (“CAD”). The Group’s 
policy is to maintain natural hedges, where possible, by matching 
revenue and receipts with expenditure. The Group continues to 
hold a large balance of GBP, to match future anticipated GBP-
denominated expenditure on continuing manufacturing, clinical 
and capital expenditure activities based in the United Kingdom.

Going Concern
Having reviewed cash flow forecasts for the 12-month period 
following the date of signing the financial statements, the 
Directors have a reasonable expectation that the Company and 
the Group have adequate resources to continue in operational 
existence for the foreseeable future. Thus, they continue to adopt 
the going concern basis in preparing these financial statements.

Employee Consultation and Human Rights
The Group places considerable value on the involvement of its 
employees. They are regularly briefed on the Group’s activities in 
Company-wide meetings and updates, and have regular 
opportunities to share their views with Executive Officers. Regular 
Group-wide employment surveys are conducted, with specific 
focused follow-ups to ensure that employee matters are addressed.

We believe that any individual employee’s contribution is a key 
element to the future success of the Group and accordingly, the 
majority of employees are given the opportunity to participate in 
the Company’s share capital by joining one or more of the share 
option schemes operated by the Company. Details of the share 
options issued under these plans are set out in note 23 to the 
financial statements. Equal opportunity is given to all employees 
regardless of their age, sex, colour, race, disability, religion or 
ethnic origin.

Disabled Employees
Applications for employment by disabled persons are always fully 
considered, bearing in mind the aptitudes of the applicant 
concerned. In the event of members of staff becoming disabled, 
every effort is made to ensure that their employment with the 
Group continues and that appropriate training is arranged. It is 
the policy of the Group that the training, career development and 
promotion of disabled persons should, as far as possible, be 
identical with that of other employees.

Our Employees
We aim to recruit, retain and motivate intelligent people who will 
share our passion for developing medicines that meet the needs of 
patients and who will strive to help us to achieve strategic aims. 
We appreciate that the accumulated knowledge and experience of 
our staff is one of our greatest assets and we recognise and reward 
loyalty.

As at 31 December 2018, 129 (30 September 2017: 119) of our 
staff have worked for the Group for more than five years. 50 
(2017: 57) of these have been with us for more than 10 years. We 
seek to encourage staff retention by offering participation in staff 
share option schemes, bonus schemes and the GW Above & 
Beyond scheme with which we reward those members of staff 
who have demonstrated exceptional achievements, innovative 
ideas, great teamwork and/or other praiseworthy achievements 
that go beyond the day-to-day requirements of their role.

We recruit individuals who have the skills, experience and 
positive attitude needed to optimally perform the roles that we 
need in order to help us to drive our business forward. We recruit 
without regard to sex or ethnic origin, appointing and thereafter 
promoting staff based upon merit, positive attitude and success.

GW Pharmaceuticals plc | Annual Report and Accounts 2018As a business whose core activity starts with the growing of 
plants which are actively absorbing carbon dioxide, we have a 
natural carbon capture process within our business operations. 
We have not sought to quantify the extent to which this offsets 
the carbon footprint of our business but we take some comfort 
from the fact that this helps to mitigate the environmental impact 
of our business and we expect this to increase as the scale of our 
growing operations expands to meet future demand for our 
plant-derived medicines.

Environmental Matters
We have reported on all of the emission sources required under 
the Companies Act 2006 (Strategic Report and Directors’ Report) 
Regulations 2013. Our sources of emission relate principally to 
our growing and manufacturing facilities, the costs of which are 
included within our consolidated financial statements. We have 
responsibility for any emission sources where we bear the 
associated costs in our consolidated statements.

We have used the Greenhouse Gas (“GHG”) Protocol Corporate 
Accounting and Reporting Standard (revised edition) data 
gathered to fulfil our requirements under the CRC Energy 
Efficiency scheme, and emission factors from UK Government’s 
GHG Conversion Factors for Company Reporting 2016.

We have used the most recent evidence or estimates provided by 
our energy supply partners to generate our disclosure of 
emissions for the 15-month period ended 31 December 2018. 
These include the purchase of electricity, heat, steam or cooling.

The annual quantity of emissions for the Group for 2018 was 
2,211 tonnes of carbon dioxide (2017: 2,417 tonnes), produced by 
activities for which the Group is responsible. The Group 
considers that the intensity ratio of tonnes of carbon dioxide per 
employee is a suitable metric for its operations. This was 3.2 
tonnes per head average (2017: 4.5 tonnes) for the 15 months 
ended 31 December 2018.

The Group is aware of the risks of climate change and actively 
looks to minimise indirect areas of emissions by encouraging 
remote working and promoting online conferencing facilities to 
reduce business-related travel and is actively exploring ways to 
reduce the light energy used in some of its plant growing 
facilities.

GW Pharmaceuticals plc | Annual Report and Accounts 2018Directors’ Remuneration Report

The information provided in this part of the Directors’ 
Remuneration Report is not subject to audit.

Remuneration Committee Chairman’s 
Annual Statement

Dear Shareholder
On behalf of the Board I am pleased to present the Remuneration 
Committee’s report for the 15-month period ended 31 December 
2018.

I would like to take this opportunity to provide you with an 
overview of the Remuneration Committee’s major decisions taken 
during 2018, together with the context in which these decisions 
were taken.

We were pleased to receive a high level of shareholder voting 
support at the Annual General Meeting (“AGM”) in March 2018, 
with over 83% of proxy voting in support of the resolution to 
adopt the 2017 Remuneration Report, and over 81% of 
shareholders supported the approval of the revised Directors’ 
Remuneration Policy. 

Context of the Committee’s Decisions in 2018
2018 has been a year of significant progress with execution of the 
Board’s strategy. The launch of Epidiolex® in the United States in 
November 2018, following approval from the Food and Drug 
Administration (“FDA”) in June 2018 was a pivotal event in the 
history of the Company. The Board continue to work on 
preparations for Epidiolex approval and launch in Europe, with 
an approval decision expected in mid-2019.

Looking forward, we are clear that the primary objective for the 
year ahead is to execute a successful US launch. We believe that 
we can continue to create shareholder value via successful 
execution of our commercial strategy whilst continuing to 
advance the development of our pipeline of other cannabinoid 
product candidates. It is in this context that the Committee have 
made our major decisions during 2018.

The Remuneration Committee
In accordance with best practice, the GW Remuneration Committee, 
consisting of independent non-executive Directors under my 
Chairmanship, manages the remuneration of the Executive 
Directors within the framework of the shareholder-approved 
Policy and shareholder-approved LTIP option scheme rules.

Our approach to remuneration:

The Group remuneration policy for Executive Directors aims to:

 > align the interests of Executive Directors with those of 

shareholders;

 > have regard to the individuals’ experience and the nature and 
complexity of their work in order to pay a competitive salary 
that attracts and retains management of the highest quality, 
while avoiding remunerating those Directors more than is 
necessary;

 > link individual remuneration packages to the Group’s 

short-term and long-term performance through the award of 
incentives via participation in the Group’s cash and equity-
based incentive schemes;

 > provide post-retirement benefits through defined contribution 

pension schemes; and

 > provide employment-related benefits including the provision of 

life assurance and medical assurance.

I believe that these aims, which remain unchanged from previous 
years, have been working well, continue to be relevant and 
provide a firm framework within which future remuneration will 
be determined. The shareholder-approved Policy provides a set of 
parameters within which we work whilst still allowing the 
Remuneration Committee sufficient flexibility to adapt 
remuneration packages in line with the development of the 
business. This should allow the Company to attract, retain and 
motivate Directors and Executive Officers with the skills, talent 
and motivation to deliver upon our strategy and to continue to 
create value for our shareholders.

Key Remuneration Committee Activities in 2018:
During 2018 the Remuneration Committee’s key activities have 
been as follows:

 > At the start of the 2018 financial year, we engaged Willis 

Towers Watson as independent advisers to benchmark the 
remuneration of the Directors against the selected peer group 
and to provide recommendations for basic salaries, Long Term 
Incentive Plan (“LTIP”) awards and the structure of bonus 
incentive awards for the year. As the Company continues to 
grow in size and complexity, the Remuneration Committee 
requested that Willis Towers Watson reviewed the peer group 
of comparable US-listed biotech/pharmaceutical development 
companies. The current peer group consists of ACADIA 
Pharmaceuticals Inc., Agios Pharmaceuticals Inc., Alder 
Biopharmaceuticals Inc., Alnylam Pharmaceuticals Inc., 
bluebird bio Inc., Clovis Oncology, Inc., Intercept 
Pharmaceuticals Inc., Juno Therapeutics Inc., Neurocrine 
Biosciences Inc., Pacira Pharmaceuticals Inc., Portola 
Pharmaceuticals Inc., Puma Biotechnology Inc., Radius Health 
Inc., Sage Therapeutics Inc., Sarepta Therapeutics Inc.,  
Spark Therapeutics, Inc., Tesaro Inc. and Ultragenyx 
Pharmaceuticals Inc. Willis Towers Watson received $31,805 
in compensation for their work relating to Directors’ 
remuneration advice.

 > In February 2018, the Remuneration Committee met to 

consider the basic salary increases to be awarded to Executive 
Officers. Inflationary increases had been given to the majority 
of our staff and the Executive Directors were given an 
inflationary basic salary increase of 3% effective from 
1 January 2018. External benchmarking analysis for the Chief 
Executive Officer and Chief Financial Officer were below the 
median of peer group data. The Remuneration Committee 
approved an increase in the Chief Executive Officer’s basic 
salary to $600,000 and the Chief Financial Officer’s basic 
salary to $400,000 effective from 1 March 2018.

 > At the same time, the Remuneration Committee met to 

consider the extent of achievement of 2017 calendar year 
objectives by the Executive Team, and to determine the level of 
short-term bonus incentive award to be paid in respect of the 
2017 calendar year. The consensus was that 2017 had been a 
year of substantial progress with all material objectives having 
been achieved, well positioning the Company for FDA 
approval. The consensus reached by the Remuneration 
Committee was that each member of the Executive Team who 
had been present throughout all of 2017 should receive a 

15

GW Pharmaceuticals plc | Annual Report and Accounts 2018Directors’ Remuneration Report continued

short-term incentive bonus award, in respect of achievements 
in the 2017 calendar year equivalent to 60% of their 2017 basic 
salary. Those members of the Executive Team who joined 
during early 2017, being the Chief Medical Officer, Chief 
Financial Officer and Chief Legal Officer, were awarded a 
short-term incentive bonus award based upon 50% of their 
pro-rata basic salary. 

 > At the same time, the Remuneration Committee approved the 
bonus objectives to be achieved by the Executive Directors 
during 2018. The approved objectives are primarily linked to 
FDA approval and execution of the Epidiolex US market 
launch. These were considered by the Remuneration 
Committee to be the key value drivers for the business and 
therefore represent the optimum objectives for Executive Team 
incentive schemes to be based upon in 2018.

 > The Remuneration Committee also met and agreed the terms of 
the 2018 grant of LTIP awards to the Directors and Executive 
Officers. These were segmented so that:
 – 50% of the value of the award is linked to specific 

performance conditions, which must be achieved in the 
three-year vesting period, with vesting dependent upon US 
approval of Epidiolex by the FDA and commercial launch in 
the US;

 – 25% of the value of the award is in the form of market-

priced share options with a three-year vesting period; and 
 – 25% of the value of the award took the form of restricted 

stock options which vest at the rate of 25% per annum over 
a four-year vesting period. 

The selected performance conditions are required to be achieved 
in order to trigger vesting of 50% of this award are again 
considered to be directly linked to key business value drivers 
creating alignment with shareholders’ interests. The restricted 
stock option element of the award is considered to encourage 
long-term retention, considered to be a key factor critical to 
future success, and the market priced options are intended to 
align the interests of the Executive Directors with shareholders’ 
interests.

At the grant date in February 2018 these awards had expected 
values at grant equivalent to 575% of basic salary for the Chief 
Executive Officer, 450% of basic salary for the Executive 
Chairman, 400% of basic salary for President, North America 
and Chief Financial Officer, 350% of basic salary for Chief Legal 
Officer and Chief Operating Officer and 300% for the Chief 
Medical Officer, and Managing Director, UK.

 > In November 2018, the Remuneration Committee met to 

consider the state of achievement of 2018 bonus objectives, to 
consider and approve the re-appointment of Willis Towers 
Watson as independent remuneration advisers to the 
committee for 2019 and to initiate a benchmarking/peer group 
refresh exercise. Finally, the Committee considered the 
potential impact of the equity incentive award limit contained 
within the shareholder approved remuneration policy and the 
potential impact upon the committee’s ability to provide 
market-competitive remuneration packages to the CEO and 
potential new senior executive officer hires in 2019.

16

Proposed change to the Remuneration Policy – for 
approval by shareholders at the Annual General Meeting 
in June 2019
As a UK registered public company, we are required by the 
Companies Act to maintain a shareholder approved remuneration 
policy containing a set of limits within which the Remuneration 
Committee has discretion to manage Directors’ remuneration. 
The policy was last approved by shareholders at the 2018 Annual 
General Meeting and has been in use throughout 2018. However, 
at the end of 2018 Peer group refresh and benchmarking exercise 
conducted on behalf of the committee by our independent 
adviser, Willis Towers Watson, together with the recruitment 
activity that we have in progress seeking to appoint a new lead US 
Commercial Officer, to fill the role that will be vacated by Julian 
Gangolli upon his retirement in early 2019, have highlighted the 
fact that the current fixed equity incentive award annual limit, 
limiting the value of equity incentive awards to a fixed 600% of 
annual salary, has the potential to frustrate the Committee’s 
ability to maintain a market competitive remuneration package 
for the Chief Executive Officer and, potentially, the Committee’s 
ability to be able to offer market-competitive remuneration 
packages that will enable recruitment and retention of the best 
candidates for senior officer roles. With this in mind, the 
Committee has consulted with independent advisers and has 
concluded that it is necessary to seek shareholder approval for a 
single amendment to the remuneration policy at the 2019 AGM, 
whereby we propose to replace the existing fixed equity incentive 
limit with a limit that is based on peer group benchmarking data, 
whereby the value of GW’s annual equity incentive awards to 
Directors and senior officers will not exceed the 75th percentile of 
peer group data. This is in-line with the approach that is currently 
taken with the policy limit for basic salary and should give the 
committee the flexibility needed to maintain market-competitive 
remuneration incentives structured similarly to those in use by 
peer group companies. 

With the exception of this single change to the equity incentive 
limit outlined above we are confident that the Remuneration 
Policy remains appropriate for the business and we intend to seek 
approval for the amended policy at the forthcoming AGM in June 
2019. On the pages that follow we set out the Remuneration 
Policy that, if approved, will be effective until 2022 unless any 
changes are required before then. We believe that the Policy set 
out on the following pages continue to give the Remuneration 
Committee transparent powers to implement appropriate 
incentive rewards, in line with US market practice, enabling us to 
continue to maintain appropriate remuneration for the existing 
Executive and non-executive Directors as they work to continue 
the success of the Company.

i)  Market-priced Options: The vesting of this award was linked to continuing employment with the Company throughout the 

three-year vesting period. 

ii)  Restricted Stock Options: The vesting period for the third and final tranche awarded during 2015 ended. The vesting of this third 

award was linked to continuing employment with the Company throughout the three-year vesting period.

iii) Performance Stock Options: The vesting of this award was linked to two performance conditions:

 – Vesting of half of the performance stock options will occur upon receipt from FDA of their confirmation of acceptance of an 

Epidiolex NDA filing.

 – Vesting of half of the performance stock options will occur upon FDA grant of Epidiolex regulatory approval.

Both conditions were met, and therefore all options vested. 

In all instances, the intrinsic value of these vested options has been included in the 2018 remuneration table above based on the share 
price at the vesting date of £9.11 per ordinary share.

On 10 August 2018, the vesting period for first tranche of Restricted Stock Options awarded to Geoffrey Guy during 2017 ended. The 
vesting of this award was linked to continuing employment with the Company throughout the vesting period. The intrinsic value of 
these vested options has been included in the 2018 remuneration table above based on the share price at the vesting date of £8.79 per 
ordinary share.

On 29 December 2018, vesting periods for two tranches of options, awarded to the Non-Executive Directors, completed:

i)  Restricted Stock Options: The vesting period for the tranche awarded during 2015 ended. The vesting of this award was linked to 

continuing service to the Company throughout the three-year vesting period.

ii)  Market-Priced Options: The vesting of this award was linked to continuing service with the Company throughout the three-year 

vesting period.

In both instances above, the intrinsic value of these vested options has been included in the 2018 remuneration table above based on 
the share price at the vesting date of £6.39 per ordinary share.

Long-Term Incentive Awards Granted to the Directors and Executive Officers in 2018
Directors and Executive Officers are awarded LTIPs at the discretion of the Remuneration Committee. Awards are typically calculated 
with reference to the closing mid-market ordinary share price of the Company’s ordinary shares on the day prior to grant. During 
periods of volatility, the price used to determine award size is determined by reference to the average closing mid-market ordinary 
share price of the previous five trading days.

Following the completion of the review of the Group’s remuneration strategy, the Directors and Executive Officers were awarded 
options to subscribe for the Company’s ordinary shares split into three different types of options:

 > market-priced options, whereby the options have an exercise price equivalent to the market price at market close on the day prior to 

grant;

 > performance stock options, whereby the options will vest upon the third anniversary of the date of grant subject to certain 

corporate performance conditions having been achieved; and

 > restricted stock options, whereby the options are subject to a four-year service condition and vesting period. 25% of the options 

will vest on each anniversary of the date of grant over the four-year period.

18

GW Pharmaceuticals plc | Annual Report and Accounts 2018In general, the awards may be exercised at any time between the vesting date and the 10th anniversary of the date of grant. Our 
US-based Directors and Executive Officers will be required to exercise their performance stock and restricted stock options before 
15 March of the year following the year of vesting. The exercise price of the performance stock options and restricted stock options is 
0.1p per ordinary share, being the par value of the shares. Awards which do not vest at the end of the vesting period will lapse 
permanently. The Company’s share options are traded on NASDAQ as American Depositary Shares (“ADSs”), for which 12 ordinary 
shares equate to one ADS.

Grant Relating to Executive Directors
25% of the awards are in the form of market-priced options, whereby the options have an exercise price equivalent to the market price 
at market close on the day prior to grant ($115.31 per ADS, equivalent to 685.1p per ordinary share). These options become exercisable 
on the third anniversary of the date of grant. Future gains upon exercise of these options will be linked to the extent of share price 
growth over the vesting period. The Committee consider that this element of the awards will help to ensure continuing alignment 
between Executive and shareholders’ interests. The Black-Scholes option pricing model was used to derive the fair values.

50% of the awards are in the form of performance stock options, whereby the options will vest upon the third anniversary of the date 
of grant subject to certain corporate performance conditions having been achieved.

(i) half of the share options vested upon US approval of Epidiolex by the FDA; and 
(ii) half vest upon commercial launch in the US.

The Remuneration Committee considers these particular milestones to be important elements of our agreed strategy and the key value 
drivers for the business at this time.

25% of the awards are in the form of restricted stock options for UK-based Directors, or restricted stock units for US-based Directors, 
whereby these options are subject to a four-year service condition and vesting period. 25% of the options will vest on each anniversary 
of the date of grant over the next four years. US-based Directors’ restricted stock units are automatically exercised immediately on 
successful vesting. The committee consider that this element of the awards should help to ensure retention of our team of Executive 
Directors, a key factor for GW’s future success.

GW Pharmaceuticals plc | Annual Report and Accounts 201850% of the awards are in the form of market-priced options, whereby the options have an exercise price equivalent to the market price 
at market close on the day prior to grant ($134.09 per ADS, equivalent to 821.8p per ordinary share). These options become 
exercisable on the third anniversary of the date of grant. Future gains upon exercise of these options will be linked to the extent of 
share price growth over the vesting period. The Committee consider that this element of the awards will help to ensure continuing 
alignment between Executive and shareholders’ interests. The Black-Scholes option pricing model was used to derive the fair values.

50% of the awards are in the form of restricted stock options for UK-based Non-Executive Directors, or restricted stock units for 
US-based Non-Executive Directors, whereby these options are subject to a three-year service condition and vesting period. 33% of the 
options will vest on each anniversary of the date of grant over the next three years. US-based Directors’ restricted stock units are 
automatically exercised immediately on successful vesting. The committee consider that this element of the awards should help to 
ensure retention of our team of non-executive Directors, a key factor for GW’s future success.

Awards for Catherine Mackey, Alicia Secor and William Waldegrave included an additional joining tranche of market-priced options 
to reflect the commencement of their appointment to the Board.

In structuring these grants, the Directors were mindful of best practice advice received from Willis Towers Watson whereby the award 
of options with vesting linked to performance is considered to have the potential to impair the independence of the non-executive 
members of the Board. It is for this reason that the vesting of awards is not linked to specific future performance conditions.

The employee comparator group comprises employees in the UK and the US. We consider this to be an appropriate comparator group 
because it is representative of the Group and the employee populations are well balanced in terms of seniority and demographics. To 
provide a meaningful comparison of salary increases, a consistent employee comparator group is used by which the same individuals 
appear in the 2017 and 2018 group.

Relative Importance of Spend on Pay

The Committee has determined that total expenditure is the most relevant comparator for staff costs of the Group. Dividend 
distribution and share buy-back comparators have not been included as the Group has no history of such transactions.

The graph below shows the Group actual staff costs as compared to total expenditure for the last two financial years and illustrates the 
year-on-year growth in both. Staff costs continue to grow faster than total spend as, in addition to headcount growth we have been 
expanding our manufacturing and commercialisation team headcount in preparation for future commercialisation of Epidiolex.

GW Pharmaceuticals plc | Annual Report and Accounts 2018Directors’ Remuneration Report continued

Proposed Application of the Remuneration Policy for the Year Ended 31 December 2019

Executive Directors’ remuneration packages are considered annually and comprise a number of elements, as follows:

i) Fixed Elements of Remuneration
Fixed elements of remuneration including basic salary, pension contributions and other benefits will be set and paid in accordance 
with our Remuneration Policy. Any changes to salary will be considered in the context of a number of factors including the annual 
peer group based benchmarking exercise carried out for the Remuneration Committee by Willis Towers Watson, home-market 
location, any changes to executive responsibilities since the last review and broader employee increases.

ii) Short-Term Incentive
The Remuneration Committee met in February 2019 to assess Director and Executive Officer performance for the calendar year ended 
31 December 2018. Based upon this assessment and in accordance with the Remuneration Policy Report below, the Remuneration 
Committee awarded a cash bonus payment to each Executive Director. Further details will be provided in the 2019 Annual Report. 

iii) Long-Term Incentive Plan
The February 2016 LTIP award was scheduled to vest on 15 February 2019. This award was divided at grant into a number of tranches:

 > 25% of the awards are in the form of market-priced options, whereby the options have an exercise price equivalent to the market 

price at market close on the day prior to grant ($44.64 per ADS). These options become exercisable on the third anniversary of the 
date of grant.

 > 50% of the awards are in the form of performance stock options, whereby the options will vest upon the third anniversary of the 

date of grant subject to certain corporate performance conditions having been achieved.
–  Vesting of half of the performance stock options will occur upon receipt from FDA of their confirmation of acceptance of an 

Epidiolex NDA filing.

–  Vesting of half of the performance stock options will occur upon FDA grant of Epidiolex regulatory approval.

 > 25% of the awards are in the form of restricted stock options whereby these options are subject to a four-year service condition and 

vesting period. 25% of the options will vest on each anniversary of the date of grant over the next four years.

100% of the LTIP award vested on 15 February 2019.

iv) Non-Executive Director Fees and Equity-Based Incentives
We do not expect the level of cash-based fees to change during 2019 but we do expect there to be a further grant of equity-based 
incentives. This grant will be subject to approval by the executive members of the Board and is likely to be linked to a combination of 
share price performance and service-based conditions.

GW Pharmaceuticals plc | Annual Report and Accounts 2018Remuneration Committee Approach to Remuneration Matters

The Remuneration Committee comprises Cabot Brown and Catherine Mackey under the chairmanship of Thomas Lynch.

During the year the Committee received advice from Adam George in his capacity as Company Secretary. The Committee also retains 
Willis Towers Watson to provide ongoing peer group remuneration benchmarking, option valuations and remuneration policy related 
advice. The Committee is satisfied that Willis Towers Watson, signatories of the Remuneration Consultants’ Code of Conduct, 
provides independent and objective advice.

The terms of reference of the Remuneration Committee can be found on the GW website at www.gwpharm.com.

Statement of Voting at Annual General Meeting

The Group is committed to ongoing shareholder dialogue and the Remuneration Committee takes an active interest in voting outcomes.

Voting at our shareholder meetings is generally conducted by a show of hands by shareholders who are in attendance at the meeting. 
Such votes have resulted in unanimous approval of the Directors’ Remuneration Report at each of the last three AGMs. No votes were 
withheld.

On 14 March 2018 the Group put the Remuneration Policy to shareholders for approval and at the AGM held on that date, 83.36% of 
shareholders’ proxy votes approved the September 2017 Directors’ Remuneration Report.

In the event that we experience significant levels of shareholder votes against any remuneration-related resolutions we will seek to 
investigate the reasons for such votes and in the event that the Remuneration Committee consider that changes to the Remuneration 
Policy are appropriate, we will disclose details of proposed changes in a timely manner.

Remuneration Policy Report

The information provided in this part of the Directors’ Remuneration Report is not subject to audit.

The Remuneration Policy has been designed to ensure that Executive Directors are appropriately incentivised and rewarded for their 
performance, responsibility and experience. The Remuneration Committee aims to ensure that the policy aligns the interests of 
Directors with those of shareholders.

The Remuneration Policy that follows will be presented to shareholders at the AGM in June 2019 for a binding vote. Following 
shareholder approval this policy then became effective from the date of the AGM and will remain in use for three years, or until a 
revised policy is approved by shareholders. There will continue to be an advisory vote on the Directors’ Remuneration Report 
presented to shareholders at the AGM on an annual basis.

For the avoidance of doubt, in approving this Directors’ Remuneration Policy, authority is given to the Company to honour any 
commitments entered into with current or former Directors (such as the payment of a pension or the vesting/exercise of past share 
awards). Details of any payments to former Directors will be set out in the Annual Report on Remuneration as they arise.

Future Policy Table
The policy table on the following page describes GW’s shareholder-approved Remuneration Policy for Directors and seeks to explain 
how each element of the Directors’ remuneration packages operates.

Salaries will be reviewed annually 
by reference to market practice 
and market data, on which the 
Committee receives independent 
advice, rates of inflation, broader 
employee increases, the individual’s 
experience and scope of the role.
Salaries will be benchmarked 
against comparable roles in a 
selected peer group of other 
US-listed pharmaceutical 
development companies with 
similar market capitalisations 
and/or scale of operational 
complexity. We typically 
expect to align salaries with 
the 50th percentile of peer 
group comparator data but 
may vary from this general rule 
where we consider that special 
circumstances apply or where 
recruitment or retention of a 
particular role is required.
The Committee may also decide 
to approve future increases 
following changes to job 
responsibilities or to reflect 
experience within the role.

Company contribution to a 
personal pension/401(k) scheme 
or salary supplement. Levels will 
be reviewed annually and the 
Committee may decide to increase 
future contribution levels should 
the review indicate such a change 
is appropriate. Statutory limits to 
employer contributions will be 
applied.

Benefits currently include 
death-in-service life insurance, 
family private medical cover, 
ill-health income protection and 
a taxed cash car allowance. The 
Committee will review benefits 
offered from time to time and 
retains the discretion to add or 
substitute benefits to ensure they 
remain market competitive.
In the event that the Group 
requires a Director or Executive 
Officer to relocate, we would 
offer appropriate relocation 
assistance and would be likely to 
update the package of benefits to 
align with local market practice, 
e.g. increased health insurance 
benefits if relocating to US.

on a one-off and

Notes to the Policy Table
Clawback of incentives: The clawback policy provides that certain incentive compensation is recoverable from a Director if the 
Company is required to restate financial statements due to the misconduct of that particular Director, and that misconduct has 
significantly contributed to the need for the restatement. Generally, eligible incentive grants shall include cash short-term incentive 
awards and equity-based long-term incentive awards that have been awarded and/or vested based upon achievement of specific 
financial or operational goals which were deemed to have been achieved but which, following restatement, are considered to no longer 
have been achieved. To be effective, intention to claw back awards which have already vested and been exercised must be notified to 
the Director within 24 months of the award having vested. The Committee may effect a clawback either through a cash or equity 
repayment by the individual, or via an adjustment to an outstanding award that is yet to vest or that has vested but is not yet exercised.

Equity retention policy: To encourage executives to retain a meaningful amount of equity in the Company, a retention policy is in 
effect for Directors and Executive Officers. The purpose of this policy is to encourage ownership of the Company’s shares, promote 
alignment of the long-term interests of the Directors and Executive Officers with those of our shareholders, and promote our 
commitment to sound corporate governance. The policy is applicable to our Directors and Executive Officers, and certain other 
members of our leadership team, as nominated by our Chief Executive Officer. Under the policy, covered Directors and officers must 
retain an agreed proportion of each new equity grant issued to them after 1 January 2015, subject to the payment of any applicable 
taxes, for a period of five years from vesting until an overall level of share ownership is achieved. The target level of ownership equates 
to four times basic salary for the Chief Executive Officer and two times basic salary for the other Directors and Officers. The target 
deadline for achieving the ownership requirement is intended to be five years from implementation of the policy. Existing 
shareholdings or direct purchases of equity by executives shall contribute towards attainment of the targeted shareholding cap. The 
Committee retains the power to consider an individual ineligible for future equity incentive grants if the required target has not been 
achieved in a timely manner, subject to the consideration of individual circumstances.

General discretions relating to the operation of incentive plans: The committee will operate all incentive plans in accordance with Plan 
Rules and will retain full discretion over a number of areas relating to the operation and administration of these plans. This includes, 
but is not limited to, determining eligibility, setting performance conditions, determining the extent to which performance conditions 
are achieved, leaver terms and the vehicle of delivery.

and market data, on which the Committee 
receives independent advice, and reflects 
the individual’s experience, scope of the 
role, time commitment and changes to the 
job responsibilities.
Fees typically consist of a basic fee for 
non-executive Director responsibilities 
plus incremental fees for additional roles/
responsibilities such as chairmanship 
of Board sub-committees, senior non-
executive Director and US representative 
Director roles.
Fees can be paid in the form of cash or 
shares to be held until the individual 
retires from the Board. Any element of 
fees paid in the form of shares will not be 
subject to performance conditions.
The non-executive Directors do 
not receive any pension from the 
Company, nor do they participate in any 
performance-related incentive plans.

All-Employee Comparison

The following differences exist between the Company’s policy for the remuneration of Directors and Executive Officers as set out 
above and its approach to the payment of employees generally:

30

GW Pharmaceuticals plc | Annual Report and Accounts 2018 > Benefits offered to other employees are consistent with those offered to the Directors and Executive Officers.
 > All US-based employees are entitled to a contribution from the Company towards a 401(k) scheme. This is generally at the same 
level as contributions paid to the personal pension/401(k) schemes of the US-based Executive Director. UK-based employees are 
entitled to a personal pension scheme contribution equating to 6.67% of basic salary. UK-based Directors do not currently receive 
an employer’s pension contribution.

 > All employees are able to participate in the LTIP schemes although the size of LTIP awards tends to increase with seniority as there 

is a greater emphasis on performance-related pay for senior members of staff.

 > A lower level of maximum annual bonus/short-term incentive opportunity typically applies to other employees.

Approach to Recruitment Remuneration

The remuneration package for a new Director or Executive Officer, to include basic salary, benefits, pension, annual bonus/short-term 
incentive and long-term incentive awards, will be set in accordance with the terms of the Company’s prevailing approved 
Remuneration Policy at the time of appointment. The Committee will consider the role, responsibility and experience of the candidate 
and will seek independent advice and market data to help derive an appropriate level of remuneration in order to secure the right 
candidate with the required skills and experience for the role.

To facilitate recruitment, the Committee may offer additional cash and/or share-based remuneration to take account of, and 
compensate for, remuneration that the Director or Executive Officer is required to relinquish when leaving a former employer, or to 
ensure that a fully market-competitive package is offered to the candidate. Any such offer would take into account the nature, time 
horizon and performance conditions attached to any waived remuneration.

For an internal Director and Executive Officer appointment, any variable pay element awarded in respect of the prior role will be 
allowed to pay out according to its terms. In addition, any other contractual remuneration obligations existing prior to appointment 
may continue.

For external and internal appointments, the Committee may agree that the Group will provide reasonable relocation support. In all 
cases, the Committee will ensure that decisions made are in the best interests of the Group.

The remuneration for any non-executive appointments will be set in accordance with the prevailing Remuneration Policy. Typically, 
the first grant of equity-based incentive awards made after appointment of a new non-executive to the Board will be increased by 50%. 
No additional cash payments will usually be made.

Service Contracts
It is Group policy that Executive Directors should have contracts with an indefinite term providing for a maximum of 12 months’ 
notice. New appointees to the Board are typically given a six-month notice period which can then be increased to 12 months’ notice, at 
the discretion of the Remuneration Committee, once the new appointee is considered to be established within their role.

Executive Directors’ service contracts, which include details of remuneration, have been filed with the US Securities and Exchange 
Commission and so are publicly available.

The non-executive Directors have service agreements which are subject to a three-month notice period. Their remuneration is reviewed 
by the Board annually. In accordance with the Company’s Articles of Association, non-executive Directors are included in the 
requirement that one-third of Directors are subject to retirement by rotation at each AGM. James Noble and Thomas Lynch will be 
retiring by rotation at the next AGM and, being eligible, they will seek re-election.

Illustrations of the Application of the Remuneration Policy – Performance and 
Remuneration Scenarios

The following table and graphical illustrations provide an illustration of the potential remuneration for the year ended 31 December 
2019 for each of the Directors, computed in accordance with the Remuneration Policy outlined above for each of three performance 
scenarios, as follows:

The following table and graphs provide an illustration of the potential remuneration. In interpreting these scenarios it is very 
important to note that it is likely that a significant proportion of future long-term equity incentive grants to the Executive Directors are 
likely to consist partly of share options which will only have value to the Executive Directors if they are successful in generating share 
price growth during the vesting period. The Remuneration Committee believes that this approach will align the interests of Executive 
Directors with those of our shareholders. The face value of equity incentive awards shown in the graphical illustrations below is not 
therefore indicative of the amount that the Directors will earn from these awards in future, as it is principally the future growth in 
value of these awards that will generate a financial return for each Director:

This scenario assumes that the current basic salary for each Director is as per the Remuneration Committee 
determination in February 2019 (see page 26).
The value of benefits receivable for the year ended 31 December 2019 assumed to be equal to the value of benefits 
received in the year ended 31 December 2018 as set out in the single total figure of remuneration table on page 17.
The pension or 401K contribution receivable by each Director for the year ended 31 December 2018 is assumed to 
be in line with the current level of contributions. 
No short-term incentive payment is assumed for any Director. No vesting of long-term equity-based incentives is 
assumed.

This scenario is illustrative only and is not expected to be predictive of 2019 remuneration for either of the 
Executive Directors. 
Fixed elements of remuneration, as set out above, plus: 
On-target level of short-term incentive payment, for the Chief Executive Officer, is taken to be 60% of basic salary, 
being the on-target amount for 2019.
The Chairman is no longer entitled to an annual bonus.
This scenario assumes the grant of equity-based incentives with a Black-Scholes valuation at grant equivalent 
to 600% of basic salary to the CEO and 400% for the Chairman. It is then assumed that 50% of these awards 
will vest. We are required to illustrate the face value of these awards, i.e. where awards consist of market-priced 
option awards, the face value is derived by multiplying the number of options granted by the exercise price. For 
the purposes of the illustrations below, we have assumed that the face value of options will equate to 160% of the 
Black-Scholes value. This has been derived by reference to the most recent equity incentive award to the Directors 
in 2018.
No account is taken of share price growth over the vesting period.

This scenario is illustrative only and is not expected to be predictive of 2019 remuneration for either of the 
Executive Directors.
Fixed elements of remuneration, as set out above, plus:
On-target level of short-term incentive payment, for the Chief Executive Officer, is taken to be 150% of basic 
salary, being the maximum percentage that can be awarded by the Remuneration Committee.
This scenario assumes the grant to the Chief Executive Officer, of the maximum possible number of equity-based 
incentives per the above policy, being awards with a Black-Scholes valuation at grant equivalent to 600% of basic 
salary under the current Remuneration Policy. For the Chairman this equivalent is set at 600% of basic salary.
We are required to illustrate the face value of these awards, i.e. where awards consist of market priced option 
awards, the face value is derived by multiplying the number of options granted by the exercise price. For the 
purposes of the illustrations below, we have assumed that the face value of options will equate to 160% of the 
Black-Scholes value. This has been derived by reference to the most recent equity incentive award to the Directors 
in 2018. For illustrative purposes, it is then assumed that 100% of these awards will vest. No account is taken of 
share price growth over the vesting period. 
Operation of the equity retention policy, outlined above, will also mean that Executive Directors may only be able 
to realise a proportion of the illustrated incentive gains in 2019 as they are likely to be required to retain equity 
shares acquired under such schemes for an extended period.

Policy for Payments for Loss of Office

The Committee’s approach to payments in the event of termination is to take account of the individual circumstances including the 
reason for termination, individual performance, contractual obligations and the terms of the LTIPs in which the Director participates. 
On notice from the Company, the Company will normally continue to pay salary, pension and other benefits during the balance of the 
notice period while the individual remains an employee. Although the Director employment contracts do not provide for payment in 
lieu of notice, the Remuneration Committee may offer payment in lieu of notice if they consider that it is in the best interests of the 
Company, subject to such payment not exceeding the contractual notice entitlement. The Committee may also approve other limited 
payments in connection with a departure, which may include legal fees connected to the departure, untaken holiday/accrued vacation, 
out-placement and repatriation.

There is no automatic contractual entitlement to bonus on termination although this may be considered.

Unvested LTIP awards normally lapse although the Committee retains the power to determine, in accordance with the good 
leaver provisions of the LTIP scheme rules, what proportion of unvested awards will be retained and what proportion will lapse. 
In determining this, the Committee will give consideration to the reason for leaving, the extent of achievement of performance 
conditions at the date of leaving and may decide to time pro-rate awards.

Statement of Consideration of Employment Conditions Elsewhere in the Company

During the annual review of remuneration, the Committee considers the remuneration and terms and conditions for the broader 
employee population when determining the extent of basic salary increases for the Directors. Employees have not been consulted in 
respect of the design of the Company’s senior executive remuneration policy to date although the Committee will keep this under review.

Statement of Shareholder Views

The Remuneration Committee considers shareholder feedback received in relation to the Annual General Meeting (“AGM”) each year 
at a meeting immediately following the AGM. This feedback, plus any additional feedback received from shareholders in respect of 
remuneration matters during the financial year, is then considered as part of the Company’s annual review of remuneration policy.

GW Pharmaceuticals plc | Annual Report and Accounts 2018Directors’ Responsibilities Statement

The Directors are responsible for preparing the Annual Report 
and the financial statements in accordance with applicable law 
and regulations.

Company law requires the Directors to prepare financial 
statements for each financial year. Under that law the Directors 
are required to prepare the Group financial statements in 
accordance with International Financial Reporting Standards 
(“IFRSs”) as adopted by the European Union, as issued by the 
International Accounting Standards Board (“IASB”) and have 
also chosen to prepare the Parent Company financial statements 
under IFRSs as adopted by the European Union. Under Company 
law the Directors must not approve the financial statements 
unless they are satisfied that they give a true and fair view of the 
state of affairs of the Company and of the profit or loss of the 
Company for that period. In preparing these financial statements, 
International Accounting Standard 1 requires that Directors:

 > properly select and apply accounting policies;
 > present information, including accounting policies, in a 
manner that provides relevant, reliable, comparable and 
understandable information;

 > provide additional disclosures when compliance with the 

specific requirements in IFRSs are insufficient to enable users 
to understand the impact of particular transactions, other 
events and conditions on the entity’s financial position and 
financial performance; and

 > make an assessment of the Company’s ability to continue as a 

going concern.

The Directors are responsible for keeping adequate accounting 
records that are sufficient to show and explain the Company’s 
transactions and disclose with reasonable accuracy at any time 
the financial position of the Company and enable them to ensure 
that the financial statements comply with the Companies Act 
2006. They are also responsible for safeguarding the assets of 
the Company and hence for taking reasonable steps for the 
prevention and detection of fraud and other irregularities.

The Directors are responsible for the maintenance and integrity 
of the corporate and financial information included on the 
Company’s website. Legislation in the UK governing the 
preparation and dissemination of financial statements may differ 
from legislation in other jurisdictions.

We confirm that to the best of our knowledge:

 > the financial statements, prepared in accordance with the 

relevant financial reporting framework, give a true and fair 
view of the assets, liabilities, financial position and profit or 
loss of the Company and the undertakings included in the 
consolidation taken as a whole;

 > the strategic report includes a fair review of the development 
and performance of the business and the position of the 
Company and the undertakings included in the consolidation 
taken as a whole, together with a description of the principal 
risks and uncertainties that they face; and

 > the Annual Report and financial statements, taken as a whole, 

are fair, balanced and understandable and provide the 
information necessary for shareholders to assess the 
Company’s position and performance, business model and 
strategy.

This responsibility statement was approved by the Board of 
Directors on 28 March 2019 and is signed on its behalf by:

GW Pharmaceuticals plc | Annual Report and Accounts 2018Independent Auditor’s Report

For the 15-month period ended 31 December 2018

Report on the audit of the financial statements

Opinion
In our opinion:
 > the financial statements of GW Pharmaceuticals plc (the ‘parent Company’) and its subsidiaries (the ‘Group’) give a true and fair 

view of the state of the Group’s and of the parent Company’s affairs as at 31 December 2018 and of the Group’s loss for the 
15-month period then ended;

 > the Group financial statements have been properly prepared in accordance with International Financial Reporting Standards 
(“IFRSs”) as adopted by the European Union and IFRSs as issued by the International Accounting Standards Board (“IASB”);
 > the parent Company financial statements have been properly prepared in accordance with IFRSs as adopted by the European 

Union and as applied in accordance with the provisions of the Companies Act 2006; and

 > the financial statements have been prepared in accordance with the requirements of the Companies Act 2006.

We have audited the financial statements which comprise:
 > the Consolidated Income Statement;
 > the Consolidated Statement of Comprehensive Loss;
 > the Consolidated and Parent Company Balance Sheets;
 > the Consolidated and Parent Company Statements of Changes in Equity;
 > the Consolidated and Parent Company Cash Flow Statements; and
 > the related notes 1 to 28.

The financial reporting framework that has been applied in their preparation is applicable law and IFRSs as adopted by the European 
Union and, as regards the parent Company financial statements, as applied in accordance with the provisions of the Companies Act 2006.

Basis for Opinion

We conducted our audit in accordance with International Standards on Auditing (UK) (“ISAs (UK)”) and applicable law. Our 
responsibilities under those standards are further described in the auditor’s responsibilities for the audit of the financial statements 
section of our report.

We are independent of the Group and the parent Company in accordance with the ethical requirements that are relevant to our audit 
of the financial statements in the UK, including the Financial Reporting Council’s (the “FRC’s”) Ethical Standard as applied to listed 
entities, and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit 
evidence we have obtained is sufficient and appropriate to provide a basis for our opinion. 

Summary of our audit approach

Key audit matter

Materiality

Scoping

The key audit matter that we identified in the current year was related to the date at which Epidiolex inventory 
could start to be capitalised and the appropriateness of the methodology to determine the inventory cost 
associated with each stage of production. Epidiolex inventory was not included in the comparative balance sheet 
at 30 September 2017, but has been capitalised for the first time during this 15-month reporting period to 
31 December 2018.

The materiality that we used for the Group financial statements in the current year was $10,200,000 which was 
determined based on a blended measure including net cash flows from operations and total operating expenses 
benchmarks.

The audit of the parent company was performed by the UK Group audit team. The other significant components 
of the Group were subject to full scope audits, with work performed by both the UK Group audit team and 
component auditors in the USA. This distribution of work was a change from the prior period. The four 
components detailed further below account for 99% of the Group’s loss before tax, 99% of the Group’s net 
assets and 100% of the Group’s revenue.

Significant changes 
in our approach

The key audit matter identified in the current period is different to prior year, as discussed in further detail 
below. We have involved a component auditor in performing our audit procedures to support the opinion for the 
15-month period ended 31 December 2018.

35

GW Pharmaceuticals plc | Annual Report and Accounts 2018Independent Auditor’s Report continued

Conclusions Relating to Going Concern

We are required by ISAs (UK) to report in respect of the following matters where:
 > the Directors’ use of the going concern basis of accounting in preparation of the financial 

statements is not appropriate; or

 > the Directors have not disclosed in the financial statements any identified material uncertainties 
that may cast significant doubt about the Group’s or the parent company’s ability to continue to 
adopt the going concern basis of accounting for a period of at least 12 months from the date 
when the financial statements are authorised for issue.

We confirm that we have  
nothing material to report,  
add or draw attention to in 
respect of these matters. 

Key Audit Matters

A key audit matter is a matter that, based on professional judgement, was of most significance in our audit of the financial statements 
for the current period and includes the most significant assessed risk of material misstatement (whether or not due to fraud) that we 
identified. Key audit matters included those which had the greatest effect on: the overall audit strategy, the allocation of resources in 
the audit; and directing the efforts of the engagement team.

The matter set out below was addressed in the context of our audit of the financial statements as a whole, and in forming our opinion 
thereon, and we do not provide a separate opinion on this matter.

The key audit matter in the current period is related to Epidiolex inventory which is a new balance in the period. The prior year key 
audit matter on Research and Development (R&D) activity related to HMRC’s small or medium-sized enterprises (“SME”) scheme is 
not applicable as at 31 December 2018 as the Company no longer qualifies for the scheme.

Epidiolex inventory

Key audit matter  
description

How the scope of our  
audit responded to the  
key audit matter

Management determined that Epidiolex inventory costs should be capitalised from the date the US 
Food and Drug Administration (FDA) accepted the Epidiolex New Drug Application (NDA) on 
27 December 2017. This is a material judgement that impacts the value of Epidiolex inventory at 
31 December 2018. The Epidiolex balance at 31 December 2018 is $44.4 million (2017: $nil).

The key audit matter is in relation to the date at which Epidiolex inventory could start to be capitalised 
and the methodology to determine the inventory cost associated with each stage of production. 

Management determined the actual cost of producing Epidiolex for the period from 27 December 
2017 to 31 December 2018. The method includes detailed analysis of the actual costs incurred in 
production and, in particular, the basis for absorbing the costs based on the number of batches, 
inventory stage and buildings.
Management then determined the actual cost of the Epidiolex inventory balance at 31 December 
2018 by applying the valuation principles in accordance with IAS 2 to the inventory produced after 
27 December 2017.

In responding to this key audit matter associated with Epidiolex inventory the following procedures 
were undertaken to challenge management’s position and outcome:
 > Assessment of the Epidiolex capitalisation date in line with IAS 2 Inventories;
 > Assessment of the methodology applied by management in determining the cost of each bottle of 

Epidiolex;

 > A detailed test on the batches of Epidiolex at different production stages to determine that only 
batches produced after 27 December 2017 were included in the inventory value at 31 December 
2018;

 > Testing that the capitalised costs were appropriate and valid by tracing a sample of costs to 

supporting evidence;

 > Testing that the capitalised costs were appropriately capitalised in accordance with the 

requirements of IAS 2;

 > Key controls implemented by management to address the risk of material misstatements were 
identified. The design and implementation were assessed, and operating effectiveness of the 
controls was tested.

Key observations

Based on the procedures performed, we concluded that the capitalisation date and the methodology 
applied to calculate the cost of Epidiolex inventory are appropriate.

36

GW Pharmaceuticals plc | Annual Report and Accounts 2018Our Application of Materiality
We define materiality as the magnitude of misstatement in the financial statements that makes it probable that the economic decisions 
of a reasonably knowledgeable person would be changed or influenced. We use materiality both in planning the scope of our audit 
work and in evaluating the results of our work. 

Based on our professional judgement, we determined materiality for the financial statements as a whole as follows:

Materiality

$10,200,000 (2017: $6,300,000)

$10,100,000 (2017: $5,700,000)

Group financial statements

Parent company financial statements

The large movement in comparison to prior year 
is primarily due to the current period materiality 
being calculated based on 15-month period totals.

The large movement in comparison to prior year 
is primarily due to the current period materiality 
being calculated based on increased total assets 
in the 15-month period. 

Basis for determining  
materiality

We determined materiality based on a 
combination of benchmarks including net cash 
flows from operations and total operating 
expenses. Our materiality of $10,200,000 
represents 3.4% of total operating expenditure 
and 4.4% of net cash flows from operations.

We determined materiality based on 2% of  
total assets.

Rationale for the benchmark 
applied

We believe that a combination of total operating 
expenditure and net cash flows from operations 
is reflective of the relevant benchmarks for 
stakeholders in assessing the performance of  
the Group.

Total assets has been used as this is a non-
trading holding company and we consider this 
to be the most appropriate basis. We have 
capped this at 99% of Group materiality.

The value of the Group is derived from 
successful research and development, with a 
significant proportion of the value derived from 
the commercialisation of Epidiolex.

We have agreed with the Audit Committee that we would report to the Committee all audit differences in excess of $514,000, as well 
as differences below that threshold that, in our view, warranted reporting on qualitative grounds. We also report to the Audit 
Committee on disclosure matters that we identified when assessing the overall presentation of the financial statements.

An Overview of the Scope of Our Audit
Our Group audit was scoped by obtaining an understanding of the Group and its environment, including Group-wide controls, and 
assessing the risks of material misstatement at the Group level sufficient to give reasonable assurance that the financial statements are 
free from material misstatement.
We performed full scope audits on four significant components of the Group, located in the UK and the USA, using component 
materialities that are lower than Group materiality:
 > The parent company – GW Pharmaceuticals plc (component materiality: $10,100,000)
 > GW Pharma Limited (“GWP”) – responsible for Epidiolex manufacturing activities (component materiality: $6,200,000)
 > GW Research Limited (“GWR”) – responsible for research and development activities (component materiality: $8,200,000)
 > Greenwich Biosciences, Inc (“GBI”) – which is expanding significantly to facilitate commercialisation of Epidiolex (component 

materiality: $8,200,000).

These four significant components cover 100% of the Group’s revenue, 99% of the Group’s loss before tax and 99% of the Group’s net assets.

At the parent entity level, we also tested the consolidation process and carried out analytical procedures to confirm our conclusion 
that there were no significant risks of material misstatements of the aggregated financial information of the remaining components not 
subject to audit.

In audits for previous periods all work was performed by the UK group engagement team. In the current year, the UK group team 
engaged component auditors in the US in regard to GBI, GWP and GWR.

The group team prepared the overall audit strategy, materiality, risk assessment and provided detailed instructions to the component 
auditor including which aspects of each component’s audit work were to be performed by which team. 

The group team visited the component auditor in the US to perform a detailed workpaper review and to discuss significant audit 
matters. Telephone conference meetings were also held with the component auditor throughout the audit. 

Other Information

The Directors are responsible for the other information. The other information comprises the 
information included in the Annual Report, other than the financial statements and our auditor’s 
report thereon.

We have nothing to report in 
respect of these matters.

Our opinion on the financial statements does not cover the other information and, except to the 
extent otherwise explicitly stated in our report, we do not express any form of assurance 
conclusion thereon.

In connection with our audit of the financial statements, our responsibility is to read the other 
information and, in doing so, consider whether the other information is materially inconsistent 
with the financial statements or our knowledge obtained in the audit or otherwise appears to be 
materially misstated.

If we identify such material inconsistencies or apparent material misstatements, we are required to 
determine whether there is a material misstatement in the financial statements or a material 
misstatement of the other information. If, based on the work we have performed, we conclude that 
there is a material misstatement of this other information, we are required to report that fact.

Responsibilities of Directors

As explained more fully in the Directors’ responsibilities statement, the Directors are responsible for the preparation of the financial 
statements and for being satisfied that they give a true and fair view, and for such internal control as the Directors determine is 
necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the financial statements, the Directors are responsible for assessing the Group’s and the parent Company’s ability to 
continue as a going concern, disclosing as applicable, matters related to going concern and using the going concern basis of accounting 
unless the Directors either intend to liquidate the Group or the parent Company or to cease operations, or have no realistic alternative 
but to do so.

Auditor’s Responsibilities for the Audit of the Financial Statements

Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, 
whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, 
but is not a guarantee that an audit conducted in accordance with ISAs (UK) will always detect a material misstatement when it exists. 
Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be 
expected to influence the economic decisions of users taken on the basis of these financial statements.

A further description of our responsibilities for the audit of the financial statements is located on the FRC’s website at: www.frc.org.uk/
auditorsresponsibilities. This description forms part of our auditor’s report.

GW Pharmaceuticals plc | Annual Report and Accounts 2018Report on other legal and regulatory requirements

Opinions on other matters prescribed by the Companies Act 2006.
In our opinion the part of the Directors’ Remuneration Report to be audited has been properly prepared in accordance with the 
Companies Act 2006.

In our opinion, based on the work undertaken in the course of the audit:
 > the information given in the Strategic Report and the Directors’ Report for the financial year for which the financial statements are 

prepared is consistent with the financial statements; and

 > the Strategic Report and the Directors’ Report have been prepared in accordance with applicable legal requirements.

In the light of the knowledge and understanding of the Group and the parent Company and their environment obtained in the course 
of the audit, we have not identified any material misstatements in the Strategic Report or the Directors’ Report.

Matters on which we are required to report by exception
Adequacy of explanations received and accounting records

Under the Companies Act 2006 we are required to report to you if, in our opinion:
 > we have not received all the information and explanations we require for our audit; or
 > adequate accounting records have not been kept by the parent Company, or returns adequate 

for our audit have not been received from branches not visited by us; or

 > the parent Company financial statements are not in agreement with the accounting records 

and returns.

We have nothing to report in 
respect of these matters.

Directors’ remuneration
Under the Companies Act 2006 we are also required to report if in our opinion certain 
disclosures of Directors’ remuneration have not been made or the part of the Directors’ 
Remuneration Report to be audited is not in agreement with the accounting records and returns.

We have nothing to report in 
respect of this matter.

Use of our report
This report is made solely to the Company’s members, as a body, in accordance with Chapter 3 of Part 16 of the Companies Act 2006. 
Our audit work has been undertaken so that we might state to the Company’s members those matters we are required to state to them 
in an auditor’s report and for no other purpose. To the fullest extent permitted by law, we do not accept or assume responsibility to 
anyone other than the Company and the Company’s members as a body, for our audit work, for this report, or for the opinions we 
have formed.

GW Pharmaceuticals plc | Annual Report and Accounts 2018Notes to the Consolidated Financial Statements

For the 15 months ended 31 December 2018 and 12 months ended 30 September 2017

1. General Information

GW Pharmaceuticals plc (the “Company”) and its subsidiaries (the “Group”) are primarily involved in the development of cannabinoid 
prescription medicines using botanical extracts derived from the Cannabis plant. The Group is developing a portfolio of cannabinoid 
medicines, of which the lead product is Epidiolex®, an oral medicine for the treatment of refractory childhood epilepsies.

The Company is a public limited company, which has had American Depository Receipts (“ADRs”) registered with the US Securities 
and Exchange Commission (“SEC”) and has been listed on NASDAQ since 1 May 2013. The Company is incorporated and domiciled 
in the United Kingdom. The address of the Company’s registered office and principal place of business is Sovereign House, Vision 
Park, Histon, Cambridgeshire, CB24 9BZ, United Kingdom.

The Company has elected to modify its financial year end to 31 December from 30 September and presents 15-month results to 
31 December 2018. This is to align with the Group’s external financial reporting calendar. Consequently, the amounts presented in 
these financial statements may not be entirely comparable.

2. Significant Accounting Policies

The principal Group accounting policies are summarised below.

Basis of Accounting
The financial statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as endorsed by 
the European Union and as issued by the International Accounting Standards Board (“IASB”). The Group financial statements also 
comply with Article 4 of the European Union IAS regulation.

The financial statements have been prepared under the historical cost convention. Historical cost is generally based on the fair value of 
the consideration given in exchange for the assets and received for the liabilities. The principal accounting policies are set out below.

Going Concern
At 31 December 2018 the Group had cash and cash equivalents of $591.5 million (30 September 2017: $322.2 million). The Directors 
have considered the financial position of the Group, its cash position and forecast cash flows for the 12-month period from the date of 
this report when considering going concern. They have also considered the Group’s key risks and uncertainties affecting the likely 
development of the business. In the light of this review, the Directors have a reasonable expectation that the Company and the Group 
have adequate resources to continue in operational existence for at least a 12-month period from the date of this Report. Accordingly, 
they continue to adopt the going concern basis in preparing these financial statements.

Basis of Consolidation
The consolidated financial statements incorporate the financial statements of the Company and entities controlled by the Company 
(its subsidiaries) made up to 31 December. Subsidiaries are all entities over which the Group has the power to govern the financial and 
operating policies of the entity concerned, generally accompanying a shareholding of more than one half of the voting rights.

The results of subsidiaries acquired or disposed of during the period are included in the consolidated income statement from the 
effective date of acquisition or up to the effective date of disposal, as appropriate. Where necessary, adjustments are made to the 
financial statements of subsidiaries to bring the accounting policies used into line with those used by the Group. All intra-Group 
transactions, balances, income and expenses are eliminated on consolidation. Acquisitions are accounted for under the acquisition 
method.

In future business combinations, if a non-controlling interest in a subsidiary arises, such non-controlling interest will be identified 
separately from the Group’s equity therein. The interests of non-controlling shareholders that are present ownership interests entitling 
their holders to a proportionate share of net assets upon liquidation may initially be measured at fair value or at the non-controlling 
interests’ proportionate share of the fair value of the acquiree’s identifiable net assets. The choice of measurement is made on an 
acquisition-by-acquisition basis. Other non-controlling interests are initially measured at fair value. Subsequent to acquisition, the 
carrying amount of non-controlling interests is the amount of those interests at initial recognition plus the non-controlling interests’ 
share of subsequent changes in equity. Total comprehensive income is attributed to non-controlling interests even if this results in the 
non-controlling interests having a deficit balance.

45

GW Pharmaceuticals plc | Annual Report and Accounts 20182. Significant Accounting Policies continued

Changes in the Group’s interests in subsidiaries that do not result in a loss of control are accounted for as equity transactions. The 
carrying amount of the Group’s interests and the non-controlling interests are adjusted to reflect the changes in their relative interests 
in the subsidiaries. Any difference between the amount by which the non-controlling interests are adjusted and the fair value of the 
consideration paid or received is recognised directly in equity and attributed to the owners of the Company.

When the Group loses control of a subsidiary, the profit or loss on disposal is calculated as the difference between (i) the aggregate of 
the fair value of the consideration received and the fair value of any retained interest and (ii) the previous carrying amount of the assets 
(including goodwill), less liabilities of the subsidiary and any non-controlling interests. Amounts previously recognised in other 
comprehensive income in relation to the subsidiary are accounted for (i.e. reclassified to profit or loss or transferred directly to 
accumulated deficit) in the same manner as would be required if the relevant assets or liabilities are disposed of. The fair value of any 
investment retained in the former subsidiary at the date when control is lost is regarded as the fair value on initial recognition for 
subsequent accounting under IAS 39 Financial Instruments: Recognition and Measurement or, when applicable, the costs on initial 
recognition of an investment in an associate or jointly controlled entity.

Change of presentation currency
On 1 October 2017, the Group changed its presentation currency from Sterling to US dollars. This change has been made 
retrospectively and the 2017 full year financial statements have been restated using the following procedures:
 > Assets and liabilities were translated into US dollars at closing rates of exchange;
 > Income and expenses were translated into US dollars at average rates of exchange;
 > Differences resulting from the retranslation were taken to reserves;
 > Share capital, share premium, other reserves were translated at historic rates prevailing at the dates of transactions.

In accordance with the requirements of IAS 1 Presentation of Financial Statements, a transition balance sheet as of 1 October 2016 has 
been included within the primary financial statements.

Change of functional currency
IAS 21 The effects of changes in foreign exchange rates describes functional currency as ‘the currency of the primary economic 
environment in which an entity operates.’ Determining when the functional currency of an entity has changed is a matter of judgement 
as the determining factors may move gradually over time. The Board has concluded that the functional currency of the Company, 
under IFRS reporting standards, changed from Sterling to US dollars with effect from 1 July 2018.

The main reasons for the change were:
 > Approval of Epidiolex by the US Federal Drug Administration and the start of Epidiolex commercial sales during the period 

indicate that the majority of the Group’s commercial activity will be driven by the US pharmaceutical market. This approval was 
received in June 2018; 

 > A change in the Board structure during the period resulted in the Group no longer meeting the requirements for Foreign Private 

Issuer (FPI) status with the US Securities and Exchange Commission per the assessment as of 31 March 2018. The majority of the 
Group’s Board are now located in the United States; and

 > All of the Group’s equity fundraising activity since 2013 has been denominated in US dollars and driven by the Company’s US 

Nasdaq listing. The Company is solely listed on the US Nasdaq market, and so any potential future equity fundraising would most 
likely be denominated in US dollars.

In accordance with IAS 21, the change in functional currency has been applied prospectively from 1 July 2018.

Intangible Assets – Other
Other intangible assets are stated at cost less provisions for amortisation and impairments. Licences, patents, know-how, software and 
marketing rights separately acquired or acquired as part of a business combination are amortised over their estimated useful lives 
using the straight-line basis from the time they are available for use. The estimated useful lives for determining the amortisation take 
into account patent lives and related product application, but do not exceed their lifetime. Asset lives are reviewed annually and 
adjusted where necessary. Contingent milestone payments are recognised at the point that the contingent event becomes certain. Any 
subsequent development costs incurred by the Group and associated with acquired licences, patents, know-how or marketing rights 
are written off to the income statement when incurred, unless the criteria for recognition of an internally generated intangible asset are 
met, usually when a regulatory filing has been made in a major market and approval is considered highly probable.

Amortisation is provided so as to write off the cost of assets, less their estimated residual values, over their useful lives using the 
straight-line method, as follows:
Software 
Licences 

3 years
3 years or term of licence if longer

Notes to the Consolidated Financial Statements continuedFor the 15 months ended 31 December 2018 and 12 months ended 30 September 2017GW Pharmaceuticals plc | Annual Report and Accounts 2018Revenue
The Company has adopted IFRS 15: Revenue from Contracts with Customers (“IFRS 15”), and all the related amendments to all 
contracts using the modified approach. As required by the modified implementation method, revenue for the current period is 
accounted for under the new guidance. The comparative revenue is not restated for the impact of adopting IFRS 15; instead the current 
period opening balances are adjusted for the cumulative impact of adopting IFRS 15. Certain practical expedients prescribed in IFRS 
15 were utilised in the adoption of IFRS 15, including using historical experience to calculate transaction price for the Group’s revenue 
contracts. Under IFRS 15, an entity recognises revenue when its customer obtains control of promised goods or services, in an amount 
that reflects the consideration which the entity expects to receive in exchange for those goods or services. To determine revenue 
recognition for arrangements that an entity determines are within the scope of IFRS 15, the entity performs the following five steps: (i) 
identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; 
(iv) allocate the transaction price to the performance obligations in the contract; and (v) recognise revenue when (or as) the entity 
satisfies a performance obligation. The Group only applies the five-step model to contracts when it is probable that the entity will 
collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once 
the contract is determined to be within the scope of IFRS 15, the Group assesses the goods or services promised within each contract 
and determines those that are performance obligations, and assesses whether each promised good or service is distinct. The Group 
then recognises as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) 
the performance obligation is satisfied.

Product Sales
The Group’s product sales consist of sales of Epidiolex, which was FDA approved for sale in the United States during the current 
accounting period for use in treating Dravet syndrome and Lennox-Gastaut syndrome, two severe paediatric forms of Epilepsy. 
Product sales revenue relating to Epidiolex shipments is recognised when shipped.

Product sales also consist of sales of Sativex®, which is currently being commercialised for spasticity due to multiple sclerosis (“MS”) 
outside the United States. The Company has entered into license agreements for the commercialisation of Sativex with Almirall S.A. 
(“Almirall”), in Europe (excluding the United Kingdom) and Mexico; Bayer HealthCare AG (“Bayer”) in the United Kingdom and 
Canada; Ipsen Biopharm Ltd (“Ipsen”), in Latin America (excluding Mexico and the Islands of the Caribbean); and Neopharm Group 
(“Neopharm”) in Israel. Under these license agreements, the Group sells fully labelled Sativex vials to its commercial partners for a 
contractually agreed price, which is generally based on percentages of the commercial partners’ in-market net selling price charged to 
end customers. Product sales revenue related to Sativex shipments to commercial license partners is recognised when shipped, at 
which point the customer obtains control of the product. The Group commercialises Sativex in Australia and New Zealand through a 
consignment relationship with a local distributor. Product sales revenue related to Sativex sales in Australia and New Zealand are 
recognised when the product is sold through to the end customer.

Revenue for the Group’s product sales has not been adjusted for the effects of a financing component as the Group expects, at contract 
inception, that the period between when the Group transfers control of the product and when the Group receives payment will be one 
year or less. Product shipping and handling costs are included in cost of product sales.

For sales of Epidiolex, consistent with industry practice, limited product return rights for damages, shipment errors, and expiring 
product; provided that the return is within a specified period around the product expiration date as set forth in the applicable individual 
distribution agreement. We do not allow product returns for a product that has been dispensed to a patient. We are able to make a 
reasonable estimate of future potential product returns based on on-hand channel inventory data and sell-through data. In arriving at our 
estimate, we also consider historical product returns, the underlying product demand, and industry data specific to the speciality 
pharmaceutical distribution industry. 

The Group maintains a rebate provision for expected reimbursements to our commercial partners in circumstances in which actual net 
revenue per vial differs from expected net revenue per vial as a consequence of, as an example, ongoing pricing negotiations with local 
health authorities. The amount of our rebate provision is based on, amongst other things, monthly unit sales and in-market sales data 
received from commercial partners and represents management’s best estimate of the rebate expected to be required to settle the present 
obligation at the end of the reporting period. Provisions for rebates are established in the same period that the related sales are recorded.

Other Revenue
The Group’s other revenue primarily consists of research and development fee revenue for research and development services provided 
under a Sativex development agreement with Otsuka Pharmaceutical Co. Ltd (“Otsuka”) that was terminated in December 2017 and 
variable consideration milestone payments related to the Sativex license agreements.

The research and development fee revenue is recognised at the time the underlying services are performed.

47

GW Pharmaceuticals plc | Annual Report and Accounts 20182. Significant Accounting Policies continued

The Sativex license agreements contain provisions for the Group to earn variable consideration in the form of regulatory milestone 
payments, sales-based milestone payments, and royalty payments. The Group has no further performance obligations related to the 
regulatory milestone payments and these amounts are recognised in accordance with IFRS 15 when receipt of these payments becomes 
probable and there is no significant risk of revenue reversal. Revenue related to the sales-based milestone payments and product royalty 
payments are subject to the sales-based royalty exception under IFRS 15 and will be recognised when the underlying sales are made.

Research and Development
Expenditure on research and development activities is recognised as an expense in the period in which it is incurred prior to achieving 
regulatory approval.
An internally generated intangible asset arising from the Group’s development activities is recognised only if the following conditions 
can be demonstrated:
 > the technical feasibility of completing the intangible asset so that it will be available for use or sale;
 > the intention to complete the intangible asset and use or sell it;
 > the ability to use or sell the intangible asset;
 > how the intangible asset will generate probable future economic benefits;
 > the availability of adequate technical, financial and other resources to complete the development and to use or sell the intangible 

asset; and

 > the ability to measure reliably the expenditure attributable to the intangible asset during its development.

The Group has determined that regulatory approval is the earliest point at which the probable threshold can be achieved. All research 
and development expenditure incurred prior to achieving regulatory approval is therefore expensed as incurred.

Borrowing Costs
Borrowing costs directly attributable to the acquisition, construction or production of qualifying assets, which are assets that 
necessarily take a substantial period of time to get ready for their intended use or sale, are added to the cost of those assets, until such 
time as the assets are substantially ready for their intended use or sale. All other borrowing costs are recognised in the income 
statement using the effective interest method.

Property, Plant and Equipment
Property, plant and equipment are stated at cost, net of accumulated depreciation and any recognised impairment loss. Depreciation is 
provided so as to write off the cost of assets, less their estimated residual values, over their useful lives using the straight-line method, 
as follows:

Leasehold buildings 
Plant, machinery and lab equipment   
Office and IT equipment 
Leasehold improvements 

20 years or term of lease if shorter
3 to 20 years
3 to 5 years
4 to 20 years or term of the lease if shorter

Assets under finance leases are depreciated over their expected useful lives on the same basis as owned assets or, where shorter, over 
the term of the relevant lease.

No depreciation is provided on assets under the course of construction. Cost includes professional fees and, for qualifying assets, 
borrowing costs capitalised in accordance with the Group’s accounting policy. Depreciation on these assets commences when the 
assets are available for use.

The gain or loss arising on disposal or scrappage of an asset is determined as the difference between the sales proceeds and the 
carrying amount of the asset and is recognised in operating profit/loss.

Property, plant and equipment assets are classified as assets held-for-sale when their carrying amount is to be recovered principally 
through a sale transaction and a sale is considered highly probable in its current condition. They are stated at the lower of carrying 
amount and fair value less costs to sell. Depreciation is not recorded on assets classified as held-for-sale.

Investments in Subsidiary Companies
Investments are shown at cost less any provision for impairment. Investments in subsidiary companies which are accounted for under 
merger accounting principles are shown at the nominal value of shares issued in accordance with the provisions of Section 131 of the 
Companies Act 2006.

The carrying value of investments in subsidiary companies in the Company balance sheet is increased annually by the value of the 
capital contribution deemed to have been made by the Company in its subsidiary by the grant of equity-settled share-based payments 
to the employees of the subsidiary company. The value attributable to these equity-settled share-based payments is calculated in 
accordance with IFRS 2 Share-based Payments.

Inventories
Inventories are stated at the lower of cost and net realisable value. Cost is calculated using the weighted average cost method. Cost 
includes materials, direct labour, depreciation of manufacturing assets and an attributable proportion of manufacturing overheads 
based on normal levels of activity. Net realisable value is the estimated selling price, less all estimated costs of completion and costs to 
be incurred in marketing, selling and distribution.

If net realisable value is lower than the carrying amount, a write-down provision is recognised for the amount by which the carrying 
amount exceeds its net realisable value.

Inventories manufactured prior to regulatory approval are capitalised as an asset but provided for until there is a high probability of 
regulatory approval of the product. At the point when a high probability of regulatory approval is obtained, which can vary by territory 
and product but typically will be on acceptance of application by the relevant regulatory authority, the provision is adjusted 
appropriately to increase the carrying value to expected net realisable value, which may not exceed original cost.

Adjustments to the provision for inventories manufactured prior to regulatory approval are recorded as a component of research and 
development expenditure. Adjustments to the provision against commercial product related inventories manufactured following 
achievement of regulatory approval are recorded as a component of cost of goods.

Taxation
The tax expense represents the sum of the tax currently payable or recoverable and deferred tax. Current and deferred taxes are 
recognised in profit or loss, except when they relate to items that are recognised in other comprehensive income or directly in equity, in 
which case, the current and deferred tax are also recognised in other comprehensive income or directly in equity, respectively. Where 
current or deferred tax arises from the initial accounting for a business combination, the tax effect is included in the accounting for the 
business combination.

The tax payable or recoverable is based on taxable profit for the year. Taxable profit differs from profit before tax as reported in the 
Consolidated Income Statement because it excludes items of income or expense that are taxable or deductible in other years and it 
further excludes items that are never taxable or deductible. The Group’s liability for current tax is calculated using tax rates and laws 
that have been enacted or substantively enacted by the balance sheet date.

Deferred tax is the tax expected to be payable or recoverable on differences between carrying amounts of assets and liabilities in the 
financial statements and the corresponding tax bases used in the computation of taxable profit, and is accounted for using the balance 
sheet liability method. Deferred tax liabilities are generally recognised for all taxable temporary differences and deferred tax assets are 
recognised only to the extent that it is probable that taxable profits will be available against which deductible temporary differences 
can be utilised. Such assets and liabilities are not recognised if the temporary difference arises from the initial recognition of goodwill 
or from the initial recognition (other than in a business combination) of assets and liabilities in a transaction that affects neither the 
taxable profit nor the accounting profit.

Deferred tax liabilities are recognised for taxable temporary differences arising on investments in subsidiaries and associates, and 
interests in joint ventures, except where the Group is able to control the reversal of the temporary difference and it is probable that the 
temporary difference will not reverse in the foreseeable future.

The carrying amount of deferred tax assets is reviewed at each balance sheet date and reduced to the extent that it is no longer 
probable that sufficient future taxable profits will be available to allow all or part of the asset to be recovered.

Deferred tax is calculated at the tax rates that are expected to apply in the period when the liability is settled or the asset is realised 
based on tax laws and rates that have been enacted or substantively enacted at the balance sheet date. Deferred tax is charged or 
credited in the Consolidated Income Statement, except when it relates to items charged or credited in other comprehensive income, in 
which case the deferred tax is also dealt with in other comprehensive income.

Deferred tax assets and liabilities are offset when there is a legally enforceable right to set off current tax assets against current tax 
liabilities and when they relate to income taxes levied by the same taxation authority and the Group intends to settle its current tax 
assets and liabilities on a net basis.

(Loss)/Earnings per Share 
Basic earnings or loss per share is calculated by dividing the net profit or loss by the weighted average number of ordinary shares 
outstanding for the period, without consideration for ordinary share equivalents. Diluted profit or loss per share is computed by dividing 
the net profit or loss by the weighted average number of ordinary shares and ordinary share equivalents outstanding for the period.

For the purposes of this calculation, market-priced share options are considered to be ordinary share equivalents but are not included 
in the calculations of diluted net loss per share for the periods presented as their effect would be antidilutive. Nominal exercise-price 
options are considered ordinary share equivalents and are included in the calculation of basic weighted average shares outstanding 
once they have become vested.

49

GW Pharmaceuticals plc | Annual Report and Accounts 20182. Significant Accounting Policies continued

The Company incurred net losses for both periods presented and there were no reconciling items for potentially dilutive shares. More 
specifically, at 31 December 2018 and 30 September 2017, options totalling approximately 13.0 million ordinary shares and 7.5 million 
ordinary shares respectively were excluded from the calculation of diluted net loss per share as their effect would have been anti-dilutive.

Retirement Benefit Costs
The Group does not operate any pension plans, but makes contributions to personal pension arrangements of its Executive Directors 
and employees. The amounts charged to the Consolidated Income Statement in respect of pension costs are the contributions payable 
in the year. Differences between contributions payable in the year and contributions paid are shown as either accruals or prepayments 
in the Consolidated Balance Sheet.

Foreign Currency
The individual financial statements of each Group company are prepared in the currency of the primary economic environment in 
which it operates (its functional currency). For the purpose of the consolidated financial statements, the results and financial position 
of the Group is presented in United States Dollars (US$).

The Group additionally reassessed its functional currency and considered that the Group’s parent company, GW Pharmaceuticals plc, 
had a functional currency of US Dollars with effect from 1 July 2018.

The functional currencies of some of the Company’s subsidiaries differ from the consolidated group US dollar presentation currency. 
As a result, the assets and liabilities of these subsidiaries are translated on consolidation at the rates of exchange prevailing at the 
balance sheet date. Revenue and expenses are translated at the average rate of exchange for the period. The unrealised gain or loss 
resulting from this translation is recognised in accumulated other comprehensive income.

In preparing the financial statements of the individual companies, transactions in currencies other than the entity’s functional currency 
(foreign currencies) are recorded at the rate of exchange at the date of the transaction. Monetary assets and liabilities denominated in 
foreign currencies at the balance sheet date are retranslated at the rates of exchange prevailing at that date. Non-monetary items 
carried at fair value that are denominated in foreign currencies are translated at the rates prevailing at the date when the fair value was 
determined. Non-monetary items that are measured in terms of historical cost in a foreign currency are not retranslated.

For the purpose of presenting consolidated financial statements, the assets and liabilities of the Group’s foreign operations are 
translated at exchange rates prevailing on the balance sheet date. Income and expense items are translated at the average exchange rate 
for the period, unless exchange rates fluctuate significantly during the period, in which case the exchange rates at the date of 
transactions are used. Exchange differences arising, if any, are recognised in other comprehensive income and accumulated in equity.

Share-Based Payments
The Group operates a number of equity-settled share-based compensation plans under which the Company receives services from 
employees as consideration for equity instruments (options) of the Company. The fair value of the employee services received in exchange 
for the grant of the awards is recognised as an expense. The total amount to be expensed is determined by reference to the fair value of the 
options granted (excluding the effect of any non-market-based performance and service vesting conditions) at the date of grant.

The fair value determined at the grant date of the equity-settled share-based payments is expensed on a straight-line basis over the 
vesting period, based on the Group’s estimate of shares that will eventually vest. At each balance sheet date, the Group revises its 
estimate of the number of equity instruments expected to vest as a result of the effect of non-market-based performance and service 
vesting conditions. The impact of the revision of the original estimates, if any, is recognised in profit or loss such that the cumulative 
expense reflects the revised estimate, with a corresponding adjustment to equity reserves.

Equity-settled share-based payment transactions with parties other than employees are measured at the fair value of the goods or 
services received, except where that fair value cannot be estimated reliably, in which case they are measured at the fair value of the 
equity instruments granted, measured at the date of grant.

Leases 
Leases are classified as finance leases whenever the terms of the lease transfer substantially all the risks and rewards of ownership to 
the lessee. All other leases are classified as operating leases.

Rentals under operating leases are charged on a straight-line basis over the term of the relevant lease except where another more 
systematic basis is more representative of the time pattern in which economic benefits from the lease are consumed. Contingent rentals 
arising under operating leases are recognised as an expense in the period in which they are incurred.

In the event that lease incentives are received to enter into operating leases, such incentives are recognised as a liability. The aggregate 
benefit of incentives is recognised as a reduction of rental expense on a straight-line basis, except where another systematic basis is 
more representative of the time pattern in which economic benefits from the leased asset are consumed.

50

Notes to the Consolidated Financial Statements continuedFor the 15 months ended 31 December 2018 and 12 months ended 30 September 2017GW Pharmaceuticals plc | Annual Report and Accounts 2018Assets held under finance leases are recognised as assets of the Group at their fair value or, if lower, the present value of the minimum 
lease payments, each determined at the inception of the lease. The corresponding liability to the lessor is included in the balance sheet 
as a finance lease obligation. Lease payments are apportioned between finance charges and reduction of the finance lease obligation so 
as to achieve a constant rate of interest on the remaining balance of the liability. Finance expenses are recognised immediately in profit 
or loss, unless they are directly attributable to qualifying assets, in which case they are capitalised in accordance with the Group’s 
general policy on borrowing costs. Contingent rentals are recognised as an expense in the periods in which they are incurred.

Financial Instruments
Financial assets and liabilities are recognised in the Group’s balance sheet when the Group becomes party to the contractual 
provisions of the instrument.

All financial assets are recognised and derecognised on a trade date where the purchase or sale of a financial asset is under a contract 
whose terms require delivery of the financial asset within the timeframe established by the market concerned, and are initially 
measured at fair value, plus transaction costs, except for those financial assets classified as at fair value through profit or loss, which 
are initially measured at fair value.

Financial assets are classified into the following specified categories: financial assets “at fair value through profit or loss”, “held-to-
maturity” investments, “available-for-sale” financial assets and “loans and receivables”. The classification depends on the nature and 
purpose of the financial assets and is determined at the time of initial recognition.

For each reporting period covered herein, the Group’s financial assets were restricted to “loans and receivables”.

Loans and Receivables 
Trade receivables that have fixed or determinable payments that are not quoted in an active market are classified as “loans and 
receivables”. Loans and receivables are measured at amortised cost, less any impairment. Interest income is recognised by applying the 
effective interest rate, except for short-term receivables when the recognition of interest would be immaterial.

Trade receivables are assessed for indicators of impairment at each balance sheet date. Trade receivables are impaired where there is 
objective evidence that, as a result of one or more events that occurred after initial recognition, the estimated future cash flows of the 
receivables have been affected. Appropriate allowances for estimated irrecoverable amounts are recognised in the Consolidated Income 
Statement. The allowance recognised is measured as the difference between the asset’s carrying amount and the present value of 
estimated future cash flows discounted at the effective interest rate computed at initial recognition.

Cash and Cash Equivalents
Cash and cash equivalents comprise cash in hand and on-call deposits held with banks and other short-term highly liquid investments 
with a maturity of three months or less.

Financial Liabilities
Financial liabilities are classified as either financial liabilities “at fair value through profit and loss” or “other financial liabilities”. For 
each reporting period covered herein, the Group’s financial liabilities were restricted to “other financial liabilities”.

Other Financial Liabilities
Trade payables are initially recognised at fair value and then held at amortised cost which equates to nominal value. Long-term 
payables are discounted where the effect is material.

All borrowings are initially recorded at the amount of proceeds received, net of transaction costs. Borrowings are subsequently carried 
at amortised cost, using the effective interest method. The difference between the proceeds, net of transaction costs, and the amount 
due on redemption is recognised as a charge to the income statement over the period of the relevant borrowing.

The effective interest method is a method of calculating the amortised cost of a financial liability and of allocating interest expense 
over the relevant period. The effective interest rate is the rate that exactly discounts estimated future cash payments through the 
expected life of the financial liability or, where appropriate, a shorter period, to the net carrying amount on initial recognition.

Critical Judgements in Applying the Group’s Accounting Policies
In the application of the Group’s accounting policies, which are described above, the Board of Directors are required to make 
judgements, estimates and assumptions about the carrying amounts of assets and liabilities that are not readily apparent from other 
sources. The estimates and associated assumptions are based on historical experience and other factors that are considered to be 
relevant. Actual results may differ from these estimates.

51

GW Pharmaceuticals plc | Annual Report and Accounts 20182. Significant Accounting Policies continued

The estimates and assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognised in the period in 
which the estimate is revised if the revision affects only that period, or in the period of the revisions and future periods if the revision 
affects both current and future periods.
The following are the critical judgements, apart from those involving estimations (which are dealt with separately below), that the 
Directors have made in the process of applying the Group’s accounting policies and that have the most significant effect on the 
amounts recognised in the financial statements.

Inventories
Inventories manufactured prior to regulatory approval are capitalised as an asset but provided for until there is a high probability of 
regulatory approval of the product. 

During the period to 31 December 2018, the Group commenced capitalisation of Epidiolex inventory material and associated 
production costs at the point of acceptance of the Group’s NDA filing with FDA in December 2017. At the point of FDA approval in 
June 2018, the Group concluded that the remaining doubt of regulatory approval had been removed and the provision was adjusted to 
increase the carrying value to expected net realisable value. This adjustment to the provision was recorded as a component of research 
and development expenditure. 

Any subsequent adjustments to the provision against commercial product related inventories manufactured following achievement of 
regulatory approval have been recorded as a component of cost of goods.

Key Sources of Estimation Uncertainty
The key assumptions concerning the future, and other key sources of estimation uncertainty at the balance sheet date, that have a 
significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year, are 
discussed below.

Deferred Taxation
At the balance sheet date, the Group has accumulated tax losses of $515.0 million (30 September 2017: $272.6 million) and other 
temporary differences of $21.5 million (30 September 2017: $23.8 million) available to offset against future profits. If the value of these 
losses and other temporary differences were recognised within the Group’s balance sheet at the balance sheet date, the Group would 
be carrying an additional deferred tax asset of $91.2 million (30 September 2017: $50.4 million). However, as explained in the tax 
accounting policy note, the Group’s policy is to recognise deferred tax assets only to the extent that it is probable that future taxable 
profits, feasible tax-planning strategies, and deferred tax liabilities will be available against which the brought-forward trading losses 
can be utilised. Estimation of the level of future taxable profits is therefore required in order to determine the appropriate carrying 
value of the deferred tax asset at each balance sheet date. As such, a deferred tax asset of $8.4 million has been recognised at 
31 December 2018 (30 September 2017: $8.2 million) in respect of temporary timings differences relating to the Group’s US subsidiary 
that are expected to be fully recoverable.

Impairment of Investments in Subsidiaries and Inter-Company Receivables
The Company considers the recoverability of investments in subsidiaries and inter-Company receivables on an ongoing basis, 
whenever indicators of impairment are present. If facts and circumstances indicate that investment in subsidiaries may be impaired, 
the estimated future cash flows associated with these subsidiaries would be compared to their carrying amounts to determine if a 
write-down to fair value is necessary.

IFRS 15 Revenue from Contracts with Customers: IFRS 15 establishes a comprehensive framework for determining whether, how 
much and when revenue is recognised. It replaced IAS 18 Revenue and its related interpretations. Under IFRS 15, revenue is recognised 
when a customer obtains control of the goods or services. Determining the timing of the transfer of control – at a point in time or over 
time – requires judgement.

The Group has early-adopted IFRS 15 with practical expedients, with the effect of initially applying this standard recognised at the 
date of initial application (i.e. 1 October 2017). Accordingly, the comparative information presented for 2017 has not been restated – 
i.e. it is presented, as previously reported, under IAS 18 and related interpretations. Additionally, the disclosure requirements in IFRS 
15 have not generally been applied to comparative information.

The following table summarises the impact of transition to IFRS 15 on retained earnings at 1 October 2017.

License, collaboration and technical access fees: Under IAS 18, revenue relating to deferred signature fees was recognised in a linear fashion 
over the expected timeline of the underlying research and collaboration agreement, based on an estimate formed at inception of the agreement.

Under IFRS 15, recognition of the deferred signature fees is instead linked to the specific R&D performance obligations under the 
agreement. Per the requirements of IFRS 15, the completion of these performance obligations occurred at an earlier stage, and so leads 
to recognition of the deferred signature fee balances faster than previously accounted for under IAS 18. All performance obligations 
with the affected agreements were completed in a prior accounting period according to IFRS 15, and therefore there are no significant 
ongoing effects of the adoption of IFRS 15.

IFRS 15 did not have a significant impact on the Group’s accounting policies with respect to other revenue streams, and so no 
adjustment was required.

IFRS 16 Leases: The Group is required to adopt IFRS 16 Leases from 1 January 2019. The Group has assessed the estimated impact 
that initial application of IFRS 16 will have on its consolidated financial statements, as described below. The actual impacts of 
adopting the standard on 1 January 2019 may change because the new accounting policies are subject to change until the Group 
presents its first financial statements that include the date of initial application.

IFRS 16 introduces a single, on-balance sheet lease accounting model for lessees. A lessee recognises a right-of-use asset representing 
its right to use the underlying asset and a lease liability representing its obligation to make lease payments. There are recognition 
exemptions for short-term leases and leases of low-value items. Lessor accounting remains similar to the current standard – i.e. lessors 
continue to classify leases as finance or operating leases.

IFRS 16 replaces existing leases guidance, including IAS 17 Leases, IFRIC 4 Determining whether an Arrangement contains a Lease, 
SIC-15 Operating Leases – Incentives and SIC-27 Evaluating the Substance of Transactions Involving the Legal Form of a Lease.

The Group will recognise new assets and liabilities for its operating leases of office space, warehouse and production facilities. The 
nature of expenses related to those leases will now change because the Group will recognise a depreciation charge for right-of-use 
assets and interest expense on lease liabilities.

Previously, the Group recognised operating lease expense on a straight-line basis over the term of the lease, and recognised assets and 
liabilities only to the extent that there was a timing difference between actual lease payments and the expense recognised. In addition, 
the Group will no longer recognise provisions for operating leases that it assesses to be onerous. Instead, the Group will include the 
payments due under the lease in its lease liability. No significant impact is expected for the Group’s finance leases.

Notes to the Consolidated Financial Statements continuedFor the 15 months ended 31 December 2018 and 12 months ended 30 September 2017GW Pharmaceuticals plc | Annual Report and Accounts 2018While the Group is still finalising the adoption procedures, the Group estimates that the adoption of this standard will result in 
recognition of additional lease assets and lease liabilities on its consolidated balance sheet as of 1 January 2019 of approximately $13.0 
million to $17.0 million. The Group does not believe the adoption of IFRS 16 will materially affect its consolidated net loss or liquidity. 
The Group plans to apply IFRS 16 initially using the modified retrospective approach. Therefore, the cumulative effect of adopting 
IFRS 16 will be recognised as an adjustment to the opening balance of retained earnings at 1 January 2019, with no restatement of 
comparative information.

The Group plans to apply the practical expedient to grandfather the definition of a lease on transition. This means that it will apply 
IFRS 16 to all contracts entered into before 1 January 2019 and identified as leases in accordance with IAS 17 and IFRIC 4.

The Directors do not expect that the adoption of the remaining Standards and Interpretations in future periods will have a material 
impact on the financial statements of the Group.

3. Segmental Information

In accordance with IFRS 8 Operating Segments, the chief operating decision maker (“CODM”), who is responsible for allocating 
resources and assessing performance of the Group, has been identified as a sub-group of the Executive Leadership Team (“ELT”), 
consisting of those members charged with executive management of the Group’s business activities.

In December 2017, the Group’s research and development agreement with Otsuka was terminated by mutual agreement. As part of 
this process, the rights to develop and commercialise Sativex in the United States were returned to the Group. As a result of this, the 
recognition of certain advance payments and deferred signature fee income balances in the Income Statement was accelerated on the 
basis that no further obligations remain to be fulfilled by the Group. The Group’s CODM considered that, following this termination, 
the nature of the Group’s operations has changed such that a review of operating segments was performed. The results of this 
identified that reporting a single operating segment has become appropriate, and reflects the Group’s strategy of discovering, 
developing and commercialising novel therapeutics from its proprietary cannabinoid product platform in a broad range of disease 
areas. The subsequent FDA approval and successful commercial release of another pipeline candidate, Epidiolex, during the last 
quarter of the current financial period further confirms this strategic orientation. Accordingly, the information required under IFRS 8 
“Operating Segments”, including the respective comparative information, has been presented for the single operating segment below.

The Group has licensing agreements for the commercialisation of Sativex with Almirall S.A. in Europe (excluding the United 
Kingdom) and Mexico, Bayer HealthCare AG in the United Kingdom and Canada, Neopharm Group in Israel, Emerge Health Pty. Ltd. 
in Australasia and Malaysia and Ipsen Biopharm Ltd. in Latin America (excluding Mexico and the Islands of the Caribbean). Revenues 
include product sales, royalties, license, collaboration and technical access fees, and development and approval milestone fees.

Revenues arising from the Group’s activities during the period were as follows:

Tax credits relate to UK research and development tax credits claimed under the Corporation Tax Act 2009. In the period to 
31 December 2018, the Group was no longer eligible to claim research and development tax credits under the SME scheme. Tax 
credits are now claimed under the large company RDEC scheme and are recorded as other income in the profit and loss account.

The Group recognises in full the estimated benefit for qualifying current period UK research and development expenditures and 
resulting tax credits. Any difference in the credit ultimately received is recorded as an adjustment in respect of prior year.

The Group recognises the likely recoverable estimated benefit for qualifying current year US research and development expenditures 
and resulting tax credits. Any difference in the credit ultimately received is recorded as an adjustment in respect of prior year.

At 31 December 2018 the Group had tax losses available for carry forward of approximately $515.0 million (30 September 2017: 
$272.6 million). These losses were generated in the UK. Of such carried-forward losses, which are not subject to expiry, the Group has 
recognised a deferred tax asset of $1.7 million (30 September 2017: $2.2 million) up to the level of deferred tax liabilities arising in the 
same jurisdiction and additionally an asset supportable by taxable income projections of $nil (30 September 2017: $nil). The Group 
has also recognised a deferred tax asset of $8.4 million (30 September 2017: $8.4 million) in respect of taxable temporary timing 
differences relating to timing differences in another jurisdiction supportable by taxable income projections. In addition, the Group has 
not recognised deferred tax assets relating to other temporary differences of $21.5 million (30 September 2017: $23.8 million). These 
deferred tax assets have not been recognised as the Group’s management considers that there is insufficient future taxable income, 
taxable temporary differences and feasible tax-planning strategies to utilise all of the cumulative losses and therefore it is probable that 
the deferred tax assets will not be realised in full. If future income differs from current projections, this could significantly impact the 
tax charge or benefit in future periods.

In addition to the amount charged to the income statement and other comprehensive income, the following amounts relating to tax 
have been recognised directly in equity:

Deferred tax assets and liabilities have been offset where the Group has a legally enforceable right to do so, and intends to settle on a 
net basis. The taxing authority permits the Group to make or receive a single net payment for all UK subsidiaries. The Group’s US 
subsidiary operates in a different jurisdiction with no legally enforceable right to offset against UK tax charges or credits.

On 15 September 2016, the reduction in the main rate of corporation tax from 19% to 17% was enacted, with effect from 1 April 2020. 
This reduction to 17% received Royal Assent in February 2019. The enacted UK tax rate until 31 March 2017 was 20%.

1  As at 31 December 2018 33,054 ordinary shares were held in the ESOP trust (30 September 2017: 33,054). The effect is less than 0.1 million shares, and consequently these have 

not been presented above.

2  The Group incurred a loss in each of the financial periods above. As a result, the inclusion of potentially dilutive share options in the diluted loss per share calculation would have 
an anti-dilutive effect on the loss per share for the period. The impact of 13.0 million share options have therefore been excluded from the diluted loss per share calculation for the 
period ended 31 December 2018 (year ended 30 September 2017: 7.5 million).

Goodwill arose upon the acquisition of GW Research Limited (formerly G-Pharm Limited) in 2001. For impairment testing purposes, 
all goodwill has been allocated to the single reportable segment, as described in Note 3, as a separate cash-generating unit. Goodwill 
has an indefinite useful life and is tested annually for impairment or more frequently if there are indications of impairment.

The Group has determined the recoverable amount of the Commercial segment based on a value-in-use calculation. This calculation 
uses pre-tax cash flow projections based on financial budgets approved by management covering a two-year period. Cash flows beyond 
the two-year period are based upon detailed internal and external third-party analysis of the Group’s product opportunity, of which 
Epidiolex is a significant contributor, or are extrapolated using the estimated growth rates stated below. The projections include 
assumptions about the timing and likelihood of product launches and pricing policy.

Management has determined the following assumptions to be the key assumptions in the calculation of value-in-use for the 
Commercial segment:

Growth rate – sales volume in each period is the main driver for revenue and costs. The same growth rates have been used in financial 
budgets and are consistent with in-market run rates and internal commercial forecasts based on a 10-year period.

Long-term growth rate – A 0% growth rate has been applied after 10 years (30 September 2017: 0% after 10 years). This approach has 
been adopted by management as it is representative of the long development and product lifecycle in the pharmaceutical sector. In 
future periods, depending on the performance of the Commercial segment, it may be necessary to revise the terminal growth rate.

Discount rate – a 13.4% (30 September 2017: 15.7%) pre-tax rate has been used. This is considered appropriate for the purpose of 
impairment reviews as it reflects the current market assessment of the time value of money and the risks specific to the cash-generating unit.

Any reasonably possible change in the key assumptions on which value-in-use is based would not cause the carrying amount to exceed 
the recoverable amount of the Commercial segment.

The Company does not own any property, plant and equipment.

The net book value of property, plant and equipment at 31 December 2018 includes $5.1 million in respect of assets held under finance 
leases (30 September 2017: $6.1 million). Included in additions is $0.1 million of property, plant and equipment which is unpaid and is 
included in trade and other payables (30 September 2017: $2.7 million).

During the prior financial year, the Group’s purpose-built manufacturing and processing facility was completed and occupied. Upon 
completion the associated capitalised costs previously held in Assets Under the Course of Construction were reclassified to the 
relevant asset class for each component asset. Depreciation commenced at this date and will continue over the relevant assets’ useful 
economic lives.

Inventories with a carrying value of $35.3 million are considered to be recoverable after more than one year from the balance sheet 
date, but within the Group’s normal operating cycle (30 September 2017: $2.8 million).

The provision for inventories relates to inventories expected to be utilised in the Group’s R&D activities. The movement in the 
provision for inventories is as follows:

Opening balance
Write-down of inventories
Write off of inventories included in the provision
Reversal of write-down of inventories

The reversal of write-down is as a result of the Group achieving a successful Federal Drug Administration (FDA) approval for 
Epidiolex in the United States in June 2018. This reduced the uncertainty surrounding the recoverability of existing commercial 
inventory, and therefore resulted in the reversal of the provision on Epidiolex-related inventory accumulated prior to that date.

Write off of inventories previously provided for and reversal of write-down of inventory does not impact cash flow.

The Company did not own any inventory in the current or prior years.

Trade receivables disclosed above are classified as loans and receivables and are therefore measured at amortised cost.

Trade receivables at 31 December 2018 represent 105 days of sales (30 September 2017: 45 days). The average trade receivable days during the 
period ended 31 December 2018 was 45 days (year ended 30 September 2017: 47 days). The credit period extended to customers is 30 to 60 days.

The trade receivables balance at 31 December 2018 consisted of balances due from six customers (30 September 2017: five customers) with 
the largest single customer representing 87% (30 September 2017: 53%) of the total amount due. The Group’s customers consist of a small 
number of large pharmaceutical companies, where the risk attributable to each customer is considered to be low. The Group seeks to mitigate 
credit risk by seeking payments in advance from pharmaceutical partners for significant expenditure to be incurred on their behalf.

No interest is charged on trade receivables. No impairment losses were recognised during the period ended 31 December 2018 (year ended 
30 September 2017: $nil).

Prepayments and accrued income include $1.6 million (30 September 2017: $5.1 million) of deposits paid in advance on tangible and 
intangible fixed assets. The goods and services associated with these deposits are expected to be received by the Group within one year.

The Directors consider that the carrying value of trade receivables approximates to their fair value due to the short maturity thereof.

GW Pharmaceuticals plc | Annual Report and Accounts 201817. Trade and Other Payables continued

Trade payables principally comprise amounts outstanding for trade purchases and ongoing costs. Trade payables at 31 December 2018 
represent the equivalent of 17 days’ purchases (30 September 2017: 19 days).

The average credit period taken for trade purchases during the period ended 31 December 2018 was 19 days (year ended 30 September 
2017: 15 days).

For most suppliers, no interest is charged on invoices that are paid within a pre-agreed trade credit period. The Group has procedures 
in place to ensure that invoices are paid within agreed credit terms so as to ensure that interest charges by suppliers are minimised.

The Directors consider that the carrying value of trade payables approximates to their fair value due to the short maturity thereof.

The onerous lease provision relates to an operating lease held on a property which was vacated in order to occupy larger premises.

18. Fit Out Funding

On 19 November 2013 the Group entered into an agreement with its landlord to receive fit out funding of $13.1 million to fund the 
expansion and upgrades to manufacturing facilities. The funds were received in tranches, with the final amount received on 1 July 
2014. The repayment of the borrowing takes the form of quarterly rental payments over a period of 15 years which commenced on 
27 May 2016 when the Group entered into the associated lease of the building. As at 31 December 2018 associated interest of $3.7 
million has been incurred (30 September 2017: $3.0 million). The total liability at 31 December 2018 is $10.0 million (30 September 
2017: $11.1 million). The Group has estimated that $0.5 million of the total liability will be due within one year and the remaining 
$9.4 million is due after one year.

The liability in respect of the funding was initially recognised at the amount of proceeds received, net of transaction costs, and has 
been subsequently carried at amortised cost using the effective interest method and a rate of 7.0% (30 September 2017: 7.0%).

The following table details the Group’s remaining contractual maturity for its borrowings and the related interest payments. The tables 
are based on the undiscounted cash flows of financial liabilities based on the earliest date on which the Group could be required to 
pay. The table includes cash flows for both interest, based on the rate applicable as at 31 December 2018, and principal amounts:

It is the Group’s policy to lease certain of its property, plant and equipment under finance leases. The weighted average lease term 
remaining is 15.2 years (30 September 2017: 16.1 years). For the period ended 31 December 2018, the average effective borrowing rate 
was 7.7% (30 September 2017: 7.6%). Interest rates are fixed at the contract date. All leases to date have been on a fixed repayment 
basis and no arrangements have been entered into for contingent rental payments.

All lease obligations are denominated in Pounds Sterling.

The carrying value of the Group’s lease obligations as at 31 December 2018 approximates to their fair value.

The Group’s obligations under finance leases are generally secured by the lessors’ rights over the leased assets.

All Group and Company financial assets are current in nature. All Group financial liabilities, other than the non-current element of 
$5.7 million in respect of the obligations under finance leases (30 September 2017: $6.4 million), $0.5 million (30 September 2017: $1.7 
million) of other creditors and accruals and $9.4 million (30 September 2017: $10.6 million) of fit out funding received from the 
Group’s landlord, are current in nature. All Company financial liabilities were current in nature. In all instances, the Directors 
consider that the carrying value of financial assets and financial liabilities approximates to their fair value.

The money market liquidity fund portfolios, accounted for as cash equivalents, are managed by external third-party fund managers to 
maintain a AAA rating. The Group’s investments represent no more than 10% of each overall fund value.

Notes to the Consolidated Financial Statements continuedFor the 15 months ended 31 December 2018 and 12 months ended 30 September 2017GW Pharmaceuticals plc | Annual Report and Accounts 2018It is, and has been throughout the period ended 31 December 2018 and year ended 30 September 2017, the Group’s policy that no 
speculative trading in financial instruments shall be undertaken.

Credit Risk
Credit risk refers to the risk that a counterparty will default on its contractual obligations resulting in financial loss to the Group. The Group 
has a policy of only dealing with creditworthy counterparties, principally involving the major UK clearing banks and their wholly owned 
subsidiaries, when placing cash on deposit. In addition the Group operates a treasury policy that dictates the maximum cash balance that 
may be placed on deposit with any single institution or group. This policy is reviewed and approved by the Board of Directors.

Trade receivables represent amounts due from customers for the sale of commercial product and research funding from development 
partners, consisting primarily of a small number of major pharmaceutical companies where the credit risk is considered to be low.

At the balance sheet date, the maximum credit risk attributable to any individual counterparty was $173.4 million (30 September 
2017: $114.2 million).

The carrying amount of the financial assets recorded in the financial statements represents the Group’s maximum exposure to credit 
risk as no collateral or other credit enhancements are held.

Market Risk
The Group’s activities expose it primarily to financial risks of changes in interest rates and foreign currency exchange rates. These 
risks are managed by maintaining an appropriate mix of cash deposits in various currencies, placed with a variety of financial 
institutions for varying periods according to the Group’s expected liquidity requirements. There has been no material change to the 
Group’s exposure to market risks or the manner in which it manages and measures risk.

i) Interest Rate Risk
The Group is exposed to interest rate risk as it places surplus cash funds on deposit to earn interest income. The Group seeks to ensure 
that it secures the best commercially available interest rates from those banks that meet the Group’s stringent counterparty credit 
rating criteria. In doing so, the Group manages the term of cash deposits, up to a maximum of 90 days, in order to maximise interest 
earnings while also ensuring that it maintains sufficient readily available cash in order to meet short-term liquidity needs.

Interest income of $6.1 million (year ended 30 September 2017: $2.1 million) during the period ended 31 December 2018 was earned 
from deposits with a weighted average interest rate of 1.59% (year ended 30 September 2017: 0.89%). Therefore a 100 basis point 
increase in interest rates, a reasonable approximation of possible changes in the current economic environment, would have increased 
interest income, and reduced the loss for the period, by $3.9 million (year ended 30 September 2017: reduced loss by $2.4 million).

The Group does not have any balance sheet exposure to assets or liabilities which would increase or decrease in fair value with 
changes to interest rates.

ii) Currency Risk
The functional currency of the Company, and its subsidiary Greenwich Biosciences, Inc., is US Dollars (“US$”). The functional 
currency of each its subsidiaries apart from Greenwich Biosciences, Inc., is Pounds Sterling (“GBP”). The Group receives revenues and 
incurs expenditures in foreign currencies and is exposed to the risks of foreign exchange rate movements, with the impact recognised 
in the consolidated income statement. The Group seeks to minimise this exposure by passively maintaining foreign currency cash 
balances at levels appropriate to meet foreseeable foreign currency expenditures, converting surplus foreign currency balances into 
Pounds as soon as they arise. The Group does not use derivative contracts to manage exchange rate exposure.

Foreign Currency Sensitivity Analysis
The most significant currencies in which the Group transacts, other than Pounds Sterling, are the US Dollar, the Euro and the 
Canadian Dollar. The Group also trades in other currencies in small amounts as necessary.

The following table details the Group’s sensitivity to a 10% change in the period-end rate, which the Group feels is the maximum 
likely change in rate based upon recent currency movements, in the key foreign currency exchange rates against Pounds Sterling:

Notes to the Consolidated Financial Statements continuedFor the 15 months ended 31 December 2018 and 12 months ended 30 September 2017GW Pharmaceuticals plc | Annual Report and Accounts 2018Liquidity Risk
Responsibility for liquidity risk management rests with the Board of Directors, which has built a liquidity risk management framework 
to enable the monitoring and management of short, medium and long-term cash requirements of the business.

The Board of Directors actively monitors Group cash flows and regularly reviews projections of future cash requirements to ensure 
that appropriate levels of liquidity are maintained. The Group manages its short-term liquidity primarily by planning the maturity 
dates of cash deposits in order to time the availability of funds as liabilities fall due for payment. The Group does not maintain any 
borrowing facilities.

Cash deposits, classified as cash and cash equivalents on the balance sheet, comprise deposits placed on money markets for periods of up 
to three months and on call. The weighted average time for which the rate was fixed was 32 days (year ended 30 September 2017: 32 days).

All of the Group’s financial liabilities at each balance sheet date have maturity dates of less than 12 months from the balance sheet 
date, other than the $5.7 million in respect of the obligations under finance leases (30 September 2017: $6.4 million) and $9.4 million 
(30 September 2017: $10.6 million) of fit out funding received from the Group’s landlord. The obligations under finance leases will be 
repaid over a weighted average 15.2 year term (30 September 2017: 16.1 year term) and the fit out funding received is being repaid over 
a 15-year finance term of which repayments commenced during the year ended 30 September 2016. There have been no material 
changes to the Group’s exposure to liquidity risks or the manner in which it manages and measures liquidity risk.

In December 2017, the Group completed the first equity financing held during the period, issuing 33,120,000 ordinary shares in the 
form of American Depositary Shares (“ADSs”) listed on the NASDAQ Global market, raising net proceeds after expenses of US$297.9 
million. This took the form of 2,760,000 ADSs at a price to the public of US$115.00 per ADS. Each ADS represents 12 ordinary shares 
of 0.1p each in the capital of the Company.

Subsequently, in October 2018 the Group completed its second equity financing during the period, issuing 26,220,000 ordinary shares 
in the form of ADSs listed on the NASDAQ Global market, raising net proceeds after expenses of US$324.6 million. This took the 
form of 2,185,000 ADSs at a price to the public of US$158.00 per ADS. Each ADS represents 12 ordinary shares of 0.1p each in the 
capital of the Company.

The Company has one class of ordinary shares which carry no right to fixed income.

GW Pharmaceuticals plc | Annual Report and Accounts 201823. Share-Based Payments

Share Option Schemes
In March 2008, the Group adopted the GW Pharmaceuticals plc Long-Term Incentive Plan (“the 2008 LTIP Plan”). Share-based awards 
granted by the Group from March 2008 to March 2017 were granted under the 2008 LTIP Plan. On 14 March 2017, the Group adopted 
the GW Pharmaceuticals plc 2017 Long-Term Incentive Plan (“the 2017 LTIP Plan”). The 2017 LTIP plan authorises the Group to issue up 
to an aggregate of 15,000,000 ordinary shares, or 1,250,000 ADSs, related to share-based awards to employees, non-employee Directors 
and consultants. No grants under the 2017 LTIP Plan may be made after 13 March 2022. As of 31 December 2018, 6,706,971 ordinary 
shares have been or may be issued pursuant to share-based awards that have been granted under the 2017 LTIP Plan.

The Group issues new ordinary shares and the commensurate number of ADSs when share-based awards are exercised.

Provisions of Share-Based Awards
The Group issues nominal exercise price share options, which have an exercise price equal to the £0.001 par value per ordinary share 
of the Company’s ordinary shares, to executive officers, employees and consultants. The Group also issues market-priced options to 
executive officers and non-employee Directors. Nominal exercise priced options granted to US residents prior to April 2017 contain 
short-term expiration provisions so the awards are compliant with provisions of IRS Code 409(a). Nominal exercise price options 
granted to US residents beginning in April 2017 are awarded in the form of RSU-style options.

Substantially all of the share-based awards issued by the Group have service-based vesting conditions. Many awards also have 
non-market-based performance conditions, which must be achieved within the service-based vesting period for the awards to vest. 
These performance conditions are generally linked to operational, regulatory or strategic milestones and are designed to incentivise 
individual employees and advance the Group’s progress towards its strategic objectives. Share-based awards that do not automatically 
exercise at vest date expire ten years from the date of grant.

Share-Based Award Activity
The following tables summarise the Group’s share option activity. The number of options, the weighted average grant date fair value 
per share option, and the weighted average exercise price are all on a per ordinary share basis. The Group’s ADSs that are listed on the 
Nasdaq Global Market each represent 12 ordinary shares.

The weighted average per share fair value of market-priced options granted during the 15-month period ended 31 December 2018 was 
$5.98 (year ended 30 September 2017: $6.00).

The aggregate intrinsic value of the share options exercised in the 15 months ended 31 December 2018 was $32.3 million. The 
aggregate intrinsic value of share options exercised in the year ended 30 September 2017 was $22.9 million. As of 31 December 2018, 
the weighted average remaining contractual life of options outstanding and options exercisable are 5.1 years and 5.4 years, 
respectively. Based on the Group’s closing year-end share price of $97.39 per ADS (or $8.12 per ordinary share) at 31 December 2018, 
the aggregate intrinsic value of options outstanding and options exercisable are $97.8 million and $9.8 million, respectively.

Valuation and Expense Recognition of Share-Based Awards
The fair value of share option awards that do not contain a market condition is estimated using the Black-Scholes option-pricing model. 
The estimated fair value of each share option is then expensed over the requisite service period, which is generally the vesting period. The 
determination of fair value using the Black-Scholes model is affected by the Company’s ADS price as well as assumptions regarding a 
number of complex and subjective variables, including expected ADS price volatility, risk-free interest rate, expected dividends and 
projected employee share option exercise behaviours. Share options granted during the period ended 31 December 2018 and the year 
ended 30 September 2017 were valued using the Black-Scholes option-pricing model with the following weighted-average assumptions:

15 months to 
31 December

$9.36
$1.93

2.35%

The Group estimates its share price volatility based using a combination of historical share price volatility and the average implied 
volatility of options traded in the open market. The risk-free interest rate assumption is based on observed interest rates for the 
appropriate term of the Group’s share options. The Group has never declared or paid dividends and has no plans to do so in the 
foreseeable future. The expected option life assumption is estimated based on the mid-point between vest date and expiration date 
since the Group does not have sufficient exercise history to estimate expected option life of historical grants.

Compensation expense for share-based awards based on a service condition is recognised only for those awards that are ultimately 
expected to vest. An estimated forfeiture rate has been applied to unvested awards for the purpose of calculating compensation cost. 
Forfeitures were estimated based on historical experience. These estimates are revised, if necessary, in future periods if actual 
forfeitures differ from the estimates. Changes in forfeiture estimates impact compensation cost in the period in which the change in 
estimate occurs. Compensation expense for share-based awards with graded, service-based vesting conditions is recognised over the 
requisite service period using the accelerated attribution method.

As of 31 December 2018, total compensation cost related to non-vested share options not yet recognised was approximately $39.7 million, 
which is expected to be recognised over the next 38 months (11 months on a weighted average basis). 

24. Other Reserves

The merger reserve credit of $31.1 million (30 September 2017: credit $31.1 million) was created as a result of the acquisition by the 
Company of the entire issued share capital of GW Pharma Limited in 2001. This acquisition was effected by a share-for-share exchange 
which was merger accounted under UK Generally Accepted Accounting Practice (“UK GAAP”), in accordance with the merger relief 
provisions of Section 131 of the Companies Act 1985 (as amended) relating to the accounting for business combinations involving the 
issue of shares at a premium. In preparing consolidated financial statements, the amount by which the fair value of the shares issued 
exceeded their nominal value was recorded in a merger reserve on consolidation, rather than in a share premium account. The merger 
reserve was retained upon transition to IFRSs, as allowed under UK law. This reserve is not considered to be distributable.

The foreign exchange reserve debit of $80.6 million (30 September 2017: $71.4 million) is due to accumulated foreign exchange 
translation differences arising on translation of the group’s operations into a US Dollar presentational currency. This reserve is not 
considered to be distributable.

ESOP Reserve
The Group’s “ESOP” is an Inland Revenue-approved all-employee share scheme constituted under a trust deed. The trust holds shares 
in the Company for the benefit of and as an incentive for the employees of the Group. The trustee of the ESOP is GWP Trustee 
Company Limited, a wholly owned subsidiary of the Company. Costs incurred by the trust are expensed in the Group’s financial 
statements as incurred. Distributions from the trust are made in accordance with the scheme rules and on the recommendation of the 
Board of Directors of the Company.

Shares held in trust represent issued and fully paid up 0.1p ordinary shares and remain eligible to receive dividends. The shares held by 
the ESOP were originally acquired in 2000 for nil consideration by way of a gift from a shareholder and hence the balance on the ESOP 
reserve is nil (30 September 2017: nil).

As at the balance sheet date, the ESOP held the following shares:

102,173

The valuation methodology used to compute the share-based payment charge related to the ESOP is based on fair value at the grant 
date, which is determined by the application of a Black-Scholes share option pricing model. The assumptions underlying the Black-
Scholes model for the ESOP shares are as detailed in note 23 relating to the LTIP awards. The exercise price for shares granted under 
the ESOP is nil, and the vesting conditions include employment by the Group over a three-year vesting period from the date of grant. 
The share-based payment charge for shares granted under the ESOP plan amounted to $nil in the period ended 31 December 2018 
(year ended 30 September 2017: $nil).

As at 31 December 2018 the number and market value of shares held by the trust which have not yet unconditionally vested in 
employees is 33,054 (30 September 2017: 33,054) and $0.3 million (30 September 2017: $0.2 million) respectively.

The minimum lease payments payable under operating leases recognised as an expense in the period were $7.3 million (2017: $4.6 million).

Operating lease payments represent rentals payable by the Group for certain of its leased properties. Manufacturing and laboratory 
facilities are subject to 5 to 20-year leases, some of which have a lease break three years prior to the conclusion of the lease at the 
Group’s option. Office properties are subject to 1 to 10-year leases.

During the year ended 30 September 2016, the Group signed a commercial growing agreement with an external supplier to produce 
plant material for use in the Epidiolex development programmes and commercial release. This agreement commenced on 1 January 
2017 and includes multiple fee elements designed to incentivise cost-efficient, reliable production volumes of raw materials for use in 
research, development and commercial activities.

As part of the accounting treatment for this agreement a component operating lease was identified under the requirements of IFRIC 4 
Determining Whether an Arrangement Contains a Lease. Rental payments commenced on 1 January 2017 and continue over a five-year 
non-cancellable period. Future minimum lease payments associated with this operating lease are included in the table shown above.

Other gross payments associated with this agreement, excluding operating lease rentals and capital commitments outlined above, fall 
due as follows:

Within one year
Between two and five years

The Company has no commitments for future minimum lease payments under non-cancellable operating leases.

During the period ended 31 December 2018, Guernsey Pharmaceuticals Limited, a dormant subsidiary company under 100% indirect 
ownership of GW Pharmaceuticals Plc, was dissolved.

28. Subsequent Events

In June 2018, the Group received a Rare Pediatric Disease Priority Review Voucher (“PRV”) from the US FDA on their approval of 
Epidiolex in the United States. This PRV entitles the Group to request a priority review of a subsequent US drug application that would 
otherwise not qualify for a priority review. At 31 December 2018 the PRV is held on the balance sheet at a carrying value of $nil, which 
equates to its historic cost.

On 15 March 2019 subsequent to the period end, the Group completed the sale of its Rare Pediatric Disease Priority Review Voucher 
(“PRV)” for $105 million. The Company had received the PRV from the FDA in connection with the approval of Epidiolex.
