Message from the Chairman

It is my great pleasure to introduce our 2015 Annual 
Report.  

Enhancing core market leadership in Wireless and 
expanding diversification activity 

I am immensely proud of the excellent reputation IQE has 
established as a world leading innovator and supplier of 

During the past three years, IQE has successfully formed 
industry specific business units dedicated to each of our 

advanced semiconductor products. Our standing as the 
global leader within our industry has led to consistent 
and robust business and financial performance through 
some tough economic times. 

Our proven track-record in providing the key enabling 
technologies for today’s wireless products, coupled with 
our innovative product portfolio spanning a wide range of 

new and emerging applications, should give investors the 
confidence that IQE is uniquely positioned to provide 
excellent long-term shareholder returns. 

It is through our commitment to innovation in advanced 
semiconductor technologies that IQE is helping to shape 
the future that will transform the way we live, work and 
play.  

IQE is the world’s leading manufacturer and supplier 
of Compound Semiconductor wafers.  

Most people don’t realise when they’re accessing the 
internet on their smartphone or tablet the 
communications networks and mobile technology they 
are using would not be possible without compound 

semiconductors manufactured and supplied by IQE. 

The world of semiconductor technology is one of the 
most dynamic, advanced and fast-moving industries in 
the world. Our technologies feature in many of the 
world’s most exciting products, from the latest 
smartphones, to the future connected-world through the 
Internet of Things (IoT) and from advanced healthcare 

technologies through to electrically powered, connected 
and driverless vehicles. 

primary markets: wireless, photonics, Infrared, CPV, 
power and CMOS++ (advanced electronics) and we are 
well poised to strengthen our position to significantly 
grow our business in these markets over the coming 
years.  

The wireless market, which accounts for approximately 
70% of our sales, remains our key market in which IQE’s 

global market share is more than 50%. Although subject 
to short term inventory cycles, the wireless 
communications market continues to represent an 
exciting long term growth prospect by the proliferation of 
wireless communication, and the need for continual 
improvement in chip performance. 

The importance of maintaining and expanding a 

comprehensive Intellectual Property (IP) portfolio cannot 
be over stated, even in established markets such as our 
wireless business, where continuous improvements in 
technological performance are the key elements in 
achieving competitive advantage for IQE, our customers 
and handset manufacturers alike. 

Our photonics business, which enables a diverse range 
of end applications, from data communications and 
advanced optical-fibres, to sensors in consumer and 
industrial applications, continues to demonstrate strong 
performance and represents our fastest growing 
business segment.

Company No: 3745726 

This business unit is being propelled by our technology 
leadership in advance lasers (VCSELs), and has already 
begun the transition from development and pilot 
revenues into high volume manufacturing following a 
number of key contract wins. 

Hot on the heels of the Catapult announcement, in 
March 2016, the UK government signed a Cardiff Capital 
Region (CCR) City Deal which includes significant 
investment in technology and innovation aimed at 
bringing long term prosperity to South Wales.  

Guided by our vision that compound semiconductor 
technology is at the very heart of the next wave of the 

At the same time as announcing the Cardiff City Deal, the 
UK Chancellor also agreed to open negotiations on a 

electronics revolution, we continue to push the limits of 
materials technology, constantly improving the quality of 
existing products whilst developing new and enhanced 
capabilities.  

Collaboration and Innovation is IQE’s lifeblood. 

City Deal for the Swansea Bay Region. 

IQE has actively supported both Cardiff and Swansea 
City Deal bids, both of which open excellent 
opportunities for investment in new and emerging 
technologies that utilise compound semiconductors. 

2015 has been a pivotal year for IQE with formation of 

Unparalleled industry reputation. 

the Compound Semiconductor Centre (CSC), a joint 
venture between IQE and Cardiff University, one of 
Britain’s leading research universities. The CSC 
represents a key milestone in bringing industry and 
academia together towards a shared vision to create a 
major new compound semiconductor cluster for next-
generation technologies.  

Today we are building upon our expertise and our 
technology to create a unique global capability for new 
and emerging 21st century technologies, focusing on 
important materials such as gallium nitride (GaN) for next 
generation wireless, power and photonics applications.  

Our vision of creating a technology cluster was endorsed 
at the start of 2016 when UK Chancellor, George 

Osborne formally announced the establishment of a 
Compound Semiconductor Applications Catapult, a hub 
of excellence for applied research. The Catapult centre 
will be located in South Wales, forming part of a UK 
network of Catapults in disciplines ranging from high-
value manufacturing to space applications. IQE, along 
with Cardiff University, will form a key resource to the new 

Catapult. 

I opened my introduction with a comment about IQE’s 
enviable reputation. 

Our position in the supply chain does not provide us with 
the status of being a household name. However, it never 
ceases to amaze me at the high-esteem held for IQE 
within our industry and across our supply chains which 
include a number of major multinational blue-chip 

companies. 

Whilst we are unable to quote our customers, the 
feedback from major international events is testament to 
the professionalism, expertise and integrity of our teams. 
I would like to thank all the management and staff of IQE 
for the success of 2015. Their commitment and 
dedication continue to be the foundation of our 

achievements. 

Finally, and as always, I would also like to express my 
sincere thanks to you, my fellow shareholders, for your 
continued belief in and support of IQE.

CEO’s review

The focus of everyone at IQE, is on growing the business 

strategy: we further sharpened our strategic 

through our technical leadership. We have a solid and 
growing customer base, we are diversifying our product 
portfolio and our service offering and we are enhancing 
our technology capabilities through acquiring and 
developing new and innovative intellectual property (IP) 
and in so doing, we will create shareholder value for the 
long-term. 

IQE’s core business is the manufacture and supply of 
compound semiconductor wafer products. Our wafers 
are similar to silicon wafers that are used to make the 
silicon chips that have transformed our world over the 
last five decades. Compound semiconductors offer far 
superior performance operating at speeds more than 
100 times faster than silicon, and with a wide range of 

photonics and power efficient properties that make 
compound semiconductors the material of choice for 
today’s ever increasing demands on technology. 

Our products help to create a smarter, more advanced 
and more connected world that, every day, enriches 
people’s lives in many ways. We have a passion and a 
drive for innovation that constantly challenges 

conventional and incumbent technologies to achieve the 
higher performance levels demanded across multiple 
markets such as communications, healthcare, 
aerospace, automotive, safety & security, the Internet of 
Things and efficient energy generation and usage. 

Our strategy is clear: to use our technology leadership 

and scale to deliver the performance, cost points and 
security of supply required for mass market adoption of 
compound semiconductor materials in a demanding, 
highly technical, leading edge industry sector.  

2015 saw continued momentum in our business with the 
reinforcement of the three primary strands of our 

diversification in our markets by improving operational 
performance, we exploited our global presence and 
world leading technology platforms by entering into two 
joint venture arrangements, in Singapore and the UK, 
and we maintained our technology leadership by 
developing a broad IP portfolio through both internal 
development and strategic transactions.  

Diversifying our end markets 
Wireless products continue to represent a key part of 
IQE's core business but revenue has declined ahead of 
the next wave of innovation in smartphone and related 
communications hardware.  

In the short term, we expect  the market for wireless 
materials to grow at a rate of approximately 5%. IQE’s 

business is well underpinned with a major contract win 
(c.$55m) announced in January 2016, and  recent 
market share gains following new product qualifications. 

As in 2014, we delivered increasing underlying 
profitability and earnings, as well as strengthening our 
balance sheet as a result of lower deferred consideration 
and net debt. We should not lose sight of the fact that 

the wireless sector remains a major part of the Group’s 
future business, and will only be enhanced with the 
adoption of numerous photonics devices in next 
generation handsets. 

We anticipate significant upside potential to this growth in 
the medium term due to: innovation in smartphone 

hardware, including the adoptions of advanced sensors; 
the adoption of GaN on Silicon technology for base 
stations; the transition to 5G communications, which will 
require more advanced materials; and the combination of 
silicon with compound semiconductors using cREO for 
other wireless communication chips.

Power and energy 

IQE has built an enviable position with a number of key 
players in the rapidly growing gallium nitride (GaN) 
markets. In addition to establishing relationships with 
leading players in the power RF GaN markets for base-
stations, IQE has also been working closely with 
industrial partners, academics and government agencies 

on developing a product pipeline for GaN power device 
technologies for a range of markets from alternative 
energy sources to commercial and aerospace 
applications.  

Notably, such programmes include  active participation in 
initiatives such as the US government funded 
programme to develop GaN on silicon power switching 

technology for grid applications.  

IQE’s materials development is at an advanced stage, 
with new product launches expected over the coming 
months. 

IQE has made solid progress in its other markets, in 
line with our strategic plan. 
The Group’s revenues continue to diversify as its 
photonics sales grow rapidly. The growth in the 
photonics business follows on from strong long-term 
engagement by IQE with its customer base in the 
development of new and innovative products. The 

increasing number and quality of customer product 
development programmes is a positive lead indicator 
which is providing a high level of confidence over the 
growth outlook for photonics. A mix of applications 
contributed to this growth, particularly data centre 
connectivity, fibre-optic communications and a broad 
range of sensor products. 

Other Group business units also performed well, 
achieving a number of key technical and commercial 
milestones which is moving the Group ever closer toward 
new product launches in high volume, high growth, 
power control and energy markets. 

Infrared 

IQE is already the global market leader in the 
manufacture and supply of indium antimonide and 
gallium antimonide engineered materials that enable high 
resolution Infrared systems, with an estimated market 
share of around 80%. 

Whilst key markets are currently limited to defence 
programmes, there are likely to be major future 

opportunities in commercial markets in areas such as 
gesture recognition, 3D imaging and sensing applications 
for autonomous and driverless vehicles.

Exploiting our global presence and world leading 
technology 
IQE’s management and expert teams firmly  believe that 
Compound Semiconductor technology will play a 
significant role in the future of 21st century technologies. 

To capitalise on the opportunities ahead, the Group 
entered into two joint venture arrangements during 2015: 
one in Singapore and the other in the United Kingdom. 
The joint ventures will help provide a focal point for 
effective collaboration between industry, academia and 
government agencies for the development and 
commercialisation of next generation technologies. 

The Compound Semiconductor Development Centre 
(CSDC)  
Based in Singapore, the 
CSDC is jointly owned by 
IQE, WIN Semiconductor 
and Singapore’s National 

Technology University 
(NTU), bringing together 
local management teams with 
key academics. Its purpose is to accelerate the 
development of compound semiconductor technologies 
in Asia as well as to provide an effective incubator for 
bringing new innovations to market. It represents a highly 

innovative approach to making the most of the skills and 
talent that exist in Singapore.  

As part of its contribution to this joint venture, IQE 
provided facilities, equipment and IP to the CSDC. 

The Compound Semiconductor Centre (CSC) 
In the UK, The CSC was 
established as a Joint Venture 
between IQE and Cardiff 
University. This is a key step 

in creating the World's first 
Compound Semiconductor 
Cluster.  

IQE’s vision is to build a cluster into one of global 
significance and scale, leading to widespread economic 
benefits for the region, and providing a broad range of 
compound semiconductor capabilities to support the 

rapid growth in 21st century technologies, both in 
Europe and across the rest of the World.  

The CSC will work closely alongside other industry, 
academic and government initiatives such as Cardiff 
University’s Institute for Compound Semiconductors, also 
announced during 2015, as well as the UK government’s 

investment in a dedicated Compound Semiconductor 
Applications Catapult announced by the UK Chancellor, 
George Osborne, at the start of 2016. Both of these 
investments provide a strong endorsement for the future 
growth of our industry sector and the strength already 
established in IQE’s supply chain. 

These JVs are commercial entities seeking to develop 

and commercialise new products, to which IQE has first 
manufacturing rights. IQE’s equity share in each JV is 
~50%, and it jointly controls these JVs with its JV 
partners. 

The license revenue earned and recognised by IQE 
reflects only its share (~50%) of the gross income (ie is 
stated after the elimination of unrealised gains).  Given 

that the JVs are related parties, the licence fees were 
determined with independent validation.  

Page !8

IQE PLC | REPORT AND ANNUAL ACCOUNTS 2015  

Company No: 3745726 

These license fees are primarily upfront fees, although 
there is a recurring element.  This is consistent with the 
Group’s strategy to monetise its IP through production 
and licensing where appropriate. The Group is also 
exploring further opportunities to license IP to third 

parties.  By its nature this income is inherently lumpy.  In 
Q1 of 2016 the group has earned further upfront license 
income with JVs of approximately £2m.  

Both the CSDC and the CSC clearly highlight IQE’s 
dominant position in technology leadership, and form 
strong relationships within which IQE’s technologies will 

be embedded.  

Also in 2015, IQE was announced as a key partner in a 
new consortium to establish the United States’ first 
Integrated Photonics Institute for Manufacturing 
Innovation (IP-IMI), created as part of President Obama's 
National Network for Manufacturing Innovation (NNMI). 
The consortium, known as the American Institute for 

Manufacturing Integrated Photonics (AIM Photonics), 
comprises 55 leading industrial partners and is led by the 
Research Foundation of the State University of New York 
(SUNY). IQE’s role in the consortium is to provide 
advanced epitaxy services to the Institute partners. 
Inclusion as a key partner in this new US Manufacturing 
Institute is testament to IQE’s reputation as a global 

world leader in compound semiconductor materials, a 
key enabling technology (KET) for photonics. 

Increasing our IP portfolio 
The technology business continues to strengthen with a 
notable licensing agreement with Silex Systems Limited’s 
subsidiary, Translucent Inc. to acquire Translucent Inc.’s 
Unique cREO™ Technology. The cREO™ technology 

offers a unique approach to the manufacture of a wide 
range of innovative Compound Semiconductor on Silicon 
products, including  gallium nitride (GaN) on silicon (Si) 

for the burgeoning Power switching and RF technologies 
markets. This is a great opportunity for IQE to take the 
unique cREO™ technology to market and thereby create 
a significant new platform to drive our business into 
several new large volume areas.  

The two joint venture initiatives in Singapore and Cardiff 
are also creating next generation IP which will support 
continued economic growth and prosperity and IQE has 
licensed additional IP during 2015. 

The Group is continuing to develop a broad IP portfolio 
through both internal development, and selective 

transactions. 

A bright future 
It is widely acknowledged that compound semiconductor 
technologies will play a pivotal role in meeting global 
societal challenges of the 21st century, and are expected 
to be the next engine of growth, transforming the way we 
live and work over the coming decades in the same way 

that silicon has changed the world over the last five 
decades. The Internet of Things (IoT), big data, 
sustainable energy, electric and driverless vehicles, 
personalised healthcare and advanced communications, 
educational and entertainment technologies will all be 
enabled by compound semiconductors.  

IQE has established a leading global technical and 

commercial leadership position, and this is just the 
beginning of the compound semiconductors momentum.

A brief history of compound semiconductors

The elements  

Everything in the universe is made of 118 known 
elements. The periodic table, first published in 1869 by 
Dmitri Mendeleev, shows the elements arranged in 
groups or columns according to their properties. 

During the two decades that followed, the ability to 

control electrical currents using semiconductors allowed 
engineers to develop a range of new electronic 
technologies. 

The evolution of silicon 

In terms of electrical properties, the elements up to and 
including those in group III are in general, known as 
metals and tend to be good conductors of electricity, 

Whilst germanium is a very efficient semiconductor 
material, the ready availability of silicon (basically sand) 
made for a compelling low-cost alternative and hence a 

whilst those from group V and above are generally non-
metals and tend to be poor conductors of electricity. 

new industry was born that has, for the last five-decades, 
transformed our lives in so many ways. 

Between the metals and non-metals, (and generally in 
group IV), are elements whose electrical properties are 
somewhere between conducting and non-conducting 
(insulating). These elements, which include silicon and 
germanium, are known as semiconductors.    

Silicon has been the backbone of the electronics 
revolution from the 1960s, largely by virtue of continuous 
miniaturisation which has led to an exponential increase 
in technological performance - a concept notably 
observed by one of the founders of Intel, Gordon Moore, 

and known as “Moore’s Law”.

The behaviour of semiconducting elements was 
discovered during the 19th century and it later became 
known through experimentation that their electrical 
properties could be altered by adding very small amounts 
of different impurities and that by placing together two 
pieces of material with different impurities, an electrical 

current could be controlled by allowing it to flow in one 
direction but not the other. 

The semiconductor age is born 

It was in 1947 that William Shockley, John Bardeen and 
Walter Brattain, working at Bell Labs, built the World’s 
first transistor using the element germanium.

Bring on the compound semiconductors 

form of general lighting (LEDs) and communications 

(lasers and receivers for fibre-optics).  

The photonic and power efficiency properties offered by 
compound semiconductors that could not be achieved 
with silicon alone, will enable technologies essential in 
areas such as safety and security systems, healthcare 
technologies, aerospace and automotive applications 

including electrically powered and autonomous vehicles. 

It is our ability to harness the advanced properties of the 
full range of semiconducting materials that will drive the 
digital revolution for generations to come.  

Welcome to the world of advanced, compound 
semiconductors. 

Impressive as the impact of silicon has been on our lives, 
it has a very basic and limited set of properties that 
restricts its application in many new and emerging 
technology areas that demand ultra-high performance 
levels along with sensing and other capabilities.  

By atomically engineering crystal structures that combine 

elements either side of those in group IV of the periodic 
table (eg groups III and V), a set of new semiconductor 
materials has emerged whose enhanced properties offer 
significant performance improvements over those of 
silicon alone.  

These compound semiconductors enable high speed 
processing in excess of 100 times that of silicon, as well 

as an array of other properties including the ability to emit 
and sense light, all the way from the infrared, through 
the visible and into the ultra-violet part of the 
spectrum. 

Compound semiconductors have already 
complimented silicon in areas such as wireless 
communications, where chips made from 

material combinations such as gallium and 
arsenic (gallium arsenide, or GaAs) are found in 
virtually every smartphone where they enable high 
speed, high efficiency wireless communications in cellular 
and WiFi networks. 

Other properties offered by compound semiconductor 
materials include the ability to emit and sense light in the

EPITAXY

Epitaxy 

IQE's core business is the manufacture of compound 
semiconductor wafers or "epiwafers" using a process 
called epitaxy. 

The epitaxial growth process is a nanotechnology 
whereby complex atomic structures are produced under 
strictly controlled conditions. The end product is a pure, 
crystaline semiconductor wafer (substrate) upon which 
complex structures comprising many individual atomic 
layers are grown. 

These epitaxial layers uniquely define the wireless, 

photonic and electronic performance of our epiwafers 
which are then processed by our customers to produce 
the "chips" that are found in virtually all of today's 
technology devices and gadgets. 

Epitaxy is the first key stage in the process of 
manufacturing the critical components in a wide range of 
devices from mobile handsets to solar cells and LEDs, 

and it requires high specification cleanrooms, 
sophisticated production tools and high levels of 
intellectual property. 

IQE produces atomically engineered layers of crystalline 
materials containing a variety of semiconductor materials 
such as gallium, arsenic, aluminium, indium and 
phosphorous. 

The layers are grown onto a crystal substrate or wafer 
and the finished product containing the wafer and its 
atomically modified surface is known as an epiwafer. 

It is the number of layers, their atomic composition and 
the order in which they are grown that determines the 
precise physical, electronic and optical properties of the 
material. 

An epiwafer can include hundreds of individual layers, 
each of which may be as thin as two or three atoms. 

IQE's intellectual property (IP) or know-how is 
the science  and technology behind the materials and the 
way in which the atomic structures can be manufactured 
to yield the wide range of wireless, photonic and 
electronic properties that are essential in today's 

electronically enabled age.

Epitaxy 

The stage is set 

Epitaxy > ˈɛpɪtaksi 


noun 

In crystallography, the natural or 
artificial growth of crystals on a 
crystalline substrate that determines 
their orientation.

Epitaxy is a process for depositing layers in a highly 
controlled way to form precisely defined crystalline 
structures that have specific atomic arrangements.  

The layers deposited using an epitaxial deposition 

process are designed to produce highly specific 
electrical, optical and mechanical properties. 

Layers of atoms are arranged on a crystalline substrate 
of gallium arsenide (GaAs) or indium phosphide (InP).  

The composition of the atomic layers is varied to include 
different elements such as gallium, indium, aluminium, 

nitrogen, arsenic and phosphorous. Carefully controlled 
“impurity” atoms such as sulphur and zinc are also 
added to control the electrical properties of the material.

Change is a constant in our world.   The inexorable drive 
for electronic devices to continue to achieve higher levels 
of functionality, speed, performance and efficiency will 
unquestionably necessitate the increasing use of more 
sophisticated semiconductor materials.   These 
advanced semiconductors are enabling a range of new 

mass market applications such as gesture recognition 
and short range optical communication,  and at the 
same time disrupting some existing large markets such 
as solar energy and  power switching.  We expect that 
this rate of change will continue to accelerate. 

We have established a global manufacturing platform 
and a breadth of IP relating to the design and 

manufacture of advanced materials that is second to 
none.   We have been unwavering in our vision and have 
developed a robust strategy which gives us confidence 
over the growth prospects of the business and our   
ability to create shareholder value.

Ubiquitously enabling new and emerging technologies

The unsung heroes 

Semiconductors in the form of both silicon and 
compound semiconductors, form the heart of many of 
today’s technologies. Without semiconductors, many 
devices and applications that we rely on simply would 
not exist, yet these atomically engineered materials go 
largely unnoticed amongst the end user brands with 

which we are so familiar. 

Semiconductors are a key enabling technology that feed 
into multiple supply chains feeding a wide range of 
market sectors including: aerospace, healthcare 
technologies, aerospace, safety & security, big data and 
the Internet of Things (IoT), energy efficiency (generation 
and consumption), robotics and automotive products.

Innovation through collaboration

IQE’s vision is to be at the epicentre of the world’s first 
compound semiconductor cluster, based in the UK.  
There has been significant progress in making this a 
reality over the past 12 months, and momentum 
continues to build : 

Cardiff University is investing c.£75m in the formation 
of the Institute of Compound Semiconductors as part 

of its £300m innovation campus; 

IQE and Cardiff University invested £24m in the 
formation of the Compound Semiconductor Centre 

In January 2016 George Osborne announced £50m 
funding for a Compound Semiconductor Catapult in 
Wales, which will leverage a further £100m funding 
from Innovate UK and Industry 

In March 2016, the Cardiff City Region Deal was 
announced which identifies the emerging CS cluster in 
Cardiff as one of its 5 headline goals. 

This level of investment is recognition of the increasing 
significance of  compound semiconductor technology in 
the electronics industry, and the UK’s ambitions to build 

on its existing academic and industrial  strengths to 
develop a world class end-to-end supply chain for 
compound semiconductor technologies in the UK.  

Building a high-tech cluster 

Intellectual property relating to advanced materials is 
playing an increasing role in the evolution of the 
semiconductor industry.  It is widely accepted that 
advanced materials are needed to overcome the 
challenges and realise the opportunities facing the 
electronics industry.  This is evident from recent M&A 

activity in the CS space, including the formation of a JV 
by Qualcomm and TDK (January 2016), the acquisitions 
by II-VI Inc  of Epiworks (January 2016) and Anadigics 
(March 2016), and the pending acquisition by Sanan of 
GCS.  The prices being paid in these deals is running into 
revenue multiples of 3x to 4x,  reflecting that ‘the heat is 
rising’.   

IQE has been at the forefront of advanced 
semiconductor technology for over a quarter of a 
century.  It has built a reputation within the CS industry 
for the breadth and depth of its materials technologies 
and capabilities.  This is now becoming increasingly 
recognised outside the CS industry, where IQE is 

becoming recognised as the ‘go to’ advanced materials 
innovator and provider.  Indeed, IQE is now engaged 
directly with a number of Tier 1 OEMs, bypassing the 
normal “materials-chip-OEM” model. 

There are many examples in history that show 
collaboration is a powerful tool in accelerating innovation.  
The benefits are even greater when whole ecosystems 

“cluster” in the same location, breaking down the barriers 
created by geography and time zones.   Indeed, 
Silicon Valley in California is a prime example 
of how the benefit of clustering can propel 
an industry to a global platform. 

It is the benefits of collaboration and 
clustering that underpin IQE’s strategic 

rationale for the joint venture 
partnerships it announced during 
2015, and its highly successful Open 
Innovation programme (openiqe.com) 

The silicon supply chain is no stranger 
to the benefits of clustering.  Indeed, there 
are 4 clusters within Europe which are 

centred around the development and 
commercialisation of Silicon technology.  
These are strongholds of innovation and value 
creation, with over 800 companies and 150,000 
employees.

Strategic report: our business model

Outsourcing pioneer  

Pioneering specialisation within the compound 

In the early days of the industrial revolution it became 
absolutely necessary for manufacturers to be vertically 
integrated since there were no alternative sources of 
specialised goods and services.  

Only towards the middle of the 20th century did 
specialisation become a competitive advantage.  

However, in new and emerging technologies, the early 

adopters were in a similar position to their industrial 
revolution forefathers in that the development of new 
processes and technologies required the early pioneers 
to establish all key parts of their supply chain.  

Specialisation within the silicon industry  

Early silicon chip manufacturers found it necessary to set 
up complete vertically integrated supply chains to source 

each part of the production process from raw materials 
through to final packaged product.  

As silicon technology matured, the industry saw the 
emergence of businesses specialising in different parts of 
the process to the extent that there now exist a large 
number of “fabless” companies who outsource the entire 

production process to large specialists such as TSMC 
Ltd and Global Foundries.  

semiconductor industry  

The compound semiconductor industry shares similar 
attributes with the silicon chip industry. Some of the 
processes such as epitaxy require large scale 
investment, complex infrastructure support in the form of 
cleanrooms, environmental controls and most 
importantly, highly specialised skills and expertise.  

In 1988, IQE became the first compound semiconductor 
materials company to recognise the potential value in 
offering specialised outsourcing of compound 
semiconductor wafers and has witnessed an increasing 
trend towards this model over its twenty-five year history.  

By specialising in the complex epitaxy process, IQE 
offers its customers economies of scale, access to 

leading technology and the ability to do what they do 
best: design and refine their products.  

The high level of investment means that IQE’s business is 
highly operationally geared which facilitates significant 
scope for profitability once sales contribution exceeds 
fixed costs.  

The last decade has demonstrated an unprecedented 
number of key industry suppliers selecting outsourcing 
as a key business advantage.

Wireless  

The wireless communications market has grown rapidly 
in recent years reflecting the increasing adoption of 
wireless technology, coupled with the need for an 
increased compound semiconductor content to support 

greater sophistication of mobile devices.  

Whilst handset replacement cycles have slowed, 
innovations such as wearable devices are expected to 
reignite the desire to upgrade connected devices such as 
smartphones. Coupled with the widely held view that the 
Internet of Everything will see 50 billion connected 

devices by 2020, the overall wireless market is expected 
to continue to grow with the global roll out of LTE, 4G, 
5G and the evolution of WiFi.  

According to industry analyst, IDC, smartphone 
shipments reached 1.43 billion units in 2015, led by 
Samsung with a 24% market share (342.8 million units) 
and Apple with a 16% market share (231.5 million units). 

Gartner estimated that smartphones represented 75% of 
the total of 1.91 billion handset sales in 2015, forecasting 
modest growth of 1.9% in 2016. 

High-speed connectivity and added functionality drive the 
requirement for the advanced properties offered by 
compound semiconductor epiwafers. The global roll-out 
of wireless broadband networks such as 4G/LTE devices 
increasingly rely on compound semiconductor content 

with 5G expected to demand a quantum leap in speed, 
power and efficiency with operating frequencies 
expected to operate above 60GHz compared with less 
than 3GHz protocols for existing 4G networks.  

The migration to new WiFi standards is another major 
driver for RF components.  

The 802.11ac WiFi standard operates at 5GHz rather 
than the 2.6GHz currently used. The higher frequency 
which greatly increases the range and reliability of WiFi 
networks will further raise the demand for compound 
semiconductor based RF devices.  

Growth in the compound semiconductor content in 
smartphones will be driven by the need for more radio 

frequency functionality and greater complexity in wireless 
circuitry but will be partly mitigated by improved 
efficiencies and a drive towards reduced component 
footprints.

Company No: 3745726  

Photonics  

Photonics represents applications which emit and detect 
light. We segment this market into emitters and 
detectors, infra-red, solar and lighting.  

Emitters and detectors  

This encompasses a wide range of applications including 
optical interconnects, laser projectors, optical storage, 
cosmetic applications, gesture recognition, finger 
navigation and a wide range of other sensing 
applications.  

Optical interconnects  

Currently, wired data transmission in the home, the office 

and in data centres is largely undertaken using copper 
cables. However, data traffic is growing at an explosive 
rate due to technologies such as high definition imaging, 
video streaming, the Internet of Things (IoT) and cloud 
computing. This phenomenon is necessitating a switch 
from copper wires to optical communication. This is a 
natural evolution which mirrors the transformation that 

has already taken place in the telecoms infrastructure.  

Optical interconnects offer significantly higher-speed data 
transfers over much longer distances than their copper 
counterparts, and are much more efficient. Data centres 
have become major consumers of electrical energy, 
rivalling traditional heavy industries in terms of the power 
requirements needed to keep large warehouses full of 

servers operating and cooled. It is therefore of little 
surprise that enterprises such as data centres are 
amongst the first adopters, where optical technology 
now offers both higher performance and lower overall 
operating cost compared with copper. 

Compound semiconductor technology that enables 

optical interconnects include Vertical Cavity Surface 
Emitting Lasers (VCSELs). VCSELs are an advanced 
laser technology geared to mass production and low 
cost. IQE is the market and technology leader for VCSEL 
products, with world record data speeds in excess of 64 
Gb/s already demonstrated. 

Gesture recognition  

Gesture recognition represents the ability of electronic 
devices to recognise hand and body gestures and 
movements in order to control any device. The advanced 
properties of compound semiconductor epiwafers are a 
key component in gesture recognition devices which are 
expected to appear in many new product launches over 

the coming years.  

The potential applications for this technology extend far 
beyond gaming, from medical applications, disability 
aids, remote controls, to sign language recognition, and 
more. In fact, the use of this technology is only limited by 
human imagination, and has far reaching implications for 

how we will interface with technology in the near future. It 
is anticipated that many household appliances will be 
controlled by gesture.  

Precision focusing 

The “time of flight” measurement used for gesture 
recognition applications is also being utilised in high-
speed, precision focusing applications for a wide range 

of camera devices, including smartphones. 

Laser projection  

Conventional projection technologies utilise incandescent 
or halogen lamps as their light sources. Such devices are 
power hungry, physically bulky, have relatively short 
lifetimes and require focusing optics which can limit the 
image quality and flexibility.  

The emergence of lasers in each of the primary colours 
(red, green and blue) enables a low cost, high quality 
laser projection solution which can be miniaturised and 
does not require focusing optics. This technology is 
called pico projection.

Company No: 3745726  

Infrared  

IQE is the clear market leader in advanced gallium 
antimonide and indium antimonide substrates for use in a 

range of infrared and heat sensing applications.  

The sensitivity of current heat sensors enables a 
monochrome image so that applications such as night 
vision devices can only see in tones of green and black, 
whereas the new antimonide materials allow greater 
sensitivity so that different shades and colours can be 
distinguished, effectively producing full colour night vision 

images.  

The improved sensitivity is useful for search and rescue 
operations and the full colour night vision capability has 
major military potential in terms of enabling effective 
identification of personnel and equipment in low or zero 
visibility conditions.  

IQE is actively engaged in a number of collaborative 

programmes with leading industry players and 
government agencies in the development and supply of 
infrared materials based on antimonide (Sb) materials. 

Solid state lighting is widely viewed as the only credible 
solution to replace the incandescent light bulb. Efficient 
energy consumption will remain a key driver in the 

development and adoption of this technology, but the 
critical success factors are reducing cost and improving 
the ambience of these units.  

High quality gallium nitride on silicon (GaN on Si) provides 
the route map to achieving this, which will revolutionise 
residential and commercial lighting around the planet 
over the coming years. 

Solid state lighting (LEDs)  

Light emitting diodes (LEDs) are a high performance, low 
cost, green alternative to incandescent light bulbs.  

Global concerns about climate change and the Earth’s 
dwindling natural resources continue to be a priority for 
governments worldwide. Significant new policies and 

legislation continue to be introduced in the direction of 
renewable and highly efficient energy devices.  

Already, many continents have introduced wide-ranging 
legislation to progressively ban incandescent lighting. 
Alternative low energy, compact fluorescent lighting is 
unpopular because of perceptions of low quality lighting 

and on-going issues with heavy metal content including 
mercury. 

Solar 

Solar cells utilising compound semiconductors (called 
CPV or Concentrated PhotoVoltaics) provide the highest 
efficiencies by using multiple layers of finely tuned 
materials to absorb sunlight across a wider range of 

wavelengths.  

As a result the efficiency of this material is already in 
excess of 44%, with a roadmap to increase this to 
beyond 50% which compares with typical efficiencies of 
around 18% from amorphous silicon solar panels, while 
thin film technology is typically around 10 to 15% 
efficient. 

A further advantage of compound semiconductors is 
their tolerance of higher temperatures and robustness to 
cosmic radiation, which makes compound 
semiconductor based alternatives especially suitable for 
space power applications.

Advanced technologies  

IQE has developed a powerful range of advanced, 
engineered wafers such as germanium-on-insulator 
(GeOI), germanium-on-silicon (GeOSi) and silicon-on-
sapphire (SOS), which offer a high performance and low 
cost solution for next generation microprocessors, ultra- 

high speed/high density flash memory and MEMS 
devices such as motion sensors.  

IQE’s deal to acquire Translucent’s unique ‘cREO™’ 
technology creates a significant new platform to drive our 
business into several new large volume areas. 
Translucent’s  cREO™ technology offers a unique 
approach to the manufacture of a wide range of 

innovative Compound Semiconductor on Silicon 
products, including  gallium nitride (GaN) on silicon (Si) 
for the burgeoning Power switching and RF technologies 
markets.  The technology is protected by a wide ranging 
IP portfolio. 

IQE has established a powerful position in these 
advanced technologies, working with some of the 

biggest names in the industry, which is reflected in a 
number of joint patents awarded in conjunction with Intel 
for the production of compound semiconductor materials 
on silicon substrates.  

We believe that our intellectual property in this field has 
the potential to revolutionise the semiconductor world, 

and in so doing will create significant long-term value to 
IQE shareholders.  

Power  

Gallium nitride (GaN) is a compound semiconductor that 
offers a diverse range of RF, photonic and electronic 
properties.  

Of particular interest is the material’s ability to cope with 
high voltages, high temperature, and high power which 
makes it an ideal candidate for power control systems 

which are growing in demand driven by alternative 
energy sources such as solar, wind and wave power, and 
also the adoption of electric vehicles.  

It is estimated that globally, more than 10% of all 
electricity is ultimately “lost” due to conversion 
inefficiencies, as energy is switched from generation, to 
grid, and through to consumption. The scale of this loss 

exceeds the world’s entire supply of renewable energy 
generation.  

The power adapters that we use for our electronic 
devices, such as laptop power supplies, provide a vivid 
example of this phenomenon by virtue of the electrical 
energy that is lost in the form of heat generated through 
the conversion process.  

GaN offers superior performance and efficiency that are 
orders of magnitude better than the silicon technologies 
that dominate power switching devices today. Indeed, 
this technology has the potential to eliminate up to 90% 
of the energy lost through switching.  

Our power business has made strong progress through 

2015, achieving several key technical milestones and 
building commercial partnerships.

Strategic report: operational highlights

Also, as part of its strategy for diversification, IQE has 
engaged with major industry players across multiple 
market sectors with the aim of establishing high-tech 
supply chains or “clusters” based on compound 
semiconductor technologies. 

A key element in the formation of a compound 
semiconductor cluster was the establishment of the 

Compound Semiconductor Centre (CSC), a Joint Venture 
(JV) with Cardiff University. 

The CSC was formed in August 2015 and IQE’s 
contribution was equipment with a market value of 
£12m, which was matched by a £12m cash contribution 
from Cardiff University.  

Operational highlights during 2015 included continued 
organisational development, improvements in operational 
efficiencies and market diversification. 

Organisation development 

The Group continued with its Organisational 
Development Programme. This has involved transferring 
production between sites to improve operational 

efficiency, enabling the Group to reduce its operating 
costs and achieve its cost reduction targets. 

Improvements in operational efficiencies 

Continuous improvement is an ongoing process across 
IQE’s global operations, with numerous programmes 
under way at any given time. 

A key feature of IQE’s global footprint is the ability to 

develop and adopt best practice across multiple 
platforms, multiple products and multiple market sectors. 

Market diversification 

The Group has established six Business Units along 
market lines, to address its primary and emerging 
markets. 

Each Business Unit has a clear product and customer 
focus, but continues to benefit from the production and 
technology synergies of the whole Group. Our 
manufacturing sites monitor production efficiencies, 
delivery performance and quality, aligned to the overall 
Group objectives.

(IP) portfolio and works closely with a number of partners 

to develop and commercialise leading edge 
technologies. 

However, largely due to the highly sensitive commercial 
nature of such developments, IQE enters into non-
disclosure agreements (NDAs) with its partners to protect 
both its own and its customers’ IP. The developments 
outlined here relate to programmes about which 

information is available in the public domain. 

The Photonics Institute for Manufacturing Innovation 
(IP-IMI) 

IQE has been announced as a key partner in a new 
consortium to establish the United States’ first Integrated 
Photonics Institute for Manufacturing Innovation (IP-IMI). 

Created as part of President Obama's National Network 

for Manufacturing Innovation (NNMI), the IP-IMI is 
designed to bring industry together with academia and 
government to advance the state-of-the-art in the 
design, manufacture, testing, assembly, and packaging 
of photonic integrated circuits. 

The consortium, known as the American Institute for 

Manufacturing Integrated Photonics (AIM 
Photonics), comprises 55 leading industrial partners, 
including Intel, IBM, Infinera, HP, Honeywell and TI along 
with numerous other leading edge companies, 
universities and laboratories, and is led by the Research 
Foundation of the State University of New York (SUNY). 
IQE’s role in the consortium is to provide advanced 

epitaxy services to the Institute partners. 

The institute will provide central facilities through which 
academia, SMEs and large corporations can access 
latest technology for design and manufacture of 
photonics devices providing a route to commercialisation 
through high-value, high-volume manufacturing. 

Exclusive Licence of the Unique ‘cREO™’ 
Technology 

In September 2015, IQE signed a deal to take 

Translucent Inc’s unique ‘cREO™’ technology to market. 
The deal provides a significant new platform to drive our 
business into several new large volume areas. 
Translucent’s  cREO™ technology offers a unique 
approach to the manufacture of a wide range of 
innovative Compound Semiconductor on Silicon 
products, including  gallium nitride (GaN) on silicon (Si) 

for the burgeoning Power switching and RF technologies 
markets.  It is protected by a wide ranging IP portfolio 
consisting of 74 granted patents, and 13 additional 
patent applications. 

Gallium Nitride (GaN) 

Gallium nitride on Silicon (GaN on Si) is driving a 
technology shift in the multi-billion dollar power switching 

and LED markets. IQE has continued to push the 
technology boundaries and is making rapid progress 
both technically and in developing commercial 
relationships in the supply chain.  

This includes supplying commercially ready 100mm 
gallium nitride (GaN) on silicon carbide (SiC) epiwafers 

that were used to produce record results for both high 
gain and high power density transistor devices, enabling 
for the first time, flexible monolithic microwave integrated 
circuit (MMIC) design for efficient high-voltage/high-
power broadband operation at frequencies ranging from 
0 to 40 GHz. 

These results, achieved on our GaN on SiC epiwafers, 

demonstrate the ability of IQE to produce record-
breaking, world leading results on commercial platforms 
that enable today’s leading edge satellite 
communications and will be essential for enabling next 
generation wireless technologies.

Strategic report: financial review

Revenue  

SG & A 

Revenues of £114.0m were up 2% on 2014 (£112.0m). 
Strong growth in photonics revenues (up 28% to 
£16.0m), and the generation of license income (£8.0m) 

as a new income stream, were partially offset by a 
reduction in wireless revenues (down 11% to £79.5m).  
Revenues in other markets were broadly flat year-on-year 
at £10.5m (2014: £10.4m).   

The license income was earned from licenses to Joint 
Ventures (JVs).  These JVs are commercial entities 
seeking to develop and commercialise new products, to 

which IQE has first manufacturing rights.  IQE’s equity 
share in each JV is ~50%, and it shares control of these 
JVs with its JV partners.  The license revenue earned and 
recognised by IQE reflects only its share (~50%) of the 
gross income (ie is stated after the elimination of 
unrealised gains).  Given that the JVs are related parties, 
the licence fees were determined with independent 

validation.  These license fees are primarily upfront fees, 
although there is a recurring element.  This is consistent 
with the Group’s strategy to monetise its IP through 
production and licensing where appropriate. The Group 
is also exploring further opportunities to license IP to third 
parties.  By its nature this income is inherently lumpy.  In 
Q1 of 2016 the group has earned further upfront license 

income with JV’s of approximately £2m.    

The reduction in wireless revenues reflects the well 
publicised slowdown in the smartphone market during 
the second half of 2015, which was exacerbated by 
inventory adjustments through the supply chain.     

Gross profit 

Adjusted gross profit increased from £31.6m to £32.4m 
largely driven by the increase in revenue. Reported gross 
profit increased from £26.0m to £30.7m. As a 
percentage of sales, adjusted gross margins were stable 
at 28%, whereas reported gross margins increased from 
23% to 27%.  

Other income 

Other income of £0.8m relates to a gain on the reduction 
of the estimated remaining balance of contingent 
deferred consideration payable in respect of a previous 
acquisition. The payments under this contingent deferred 
consideration arrangement cease during 2016.  The prior 
year comparative was a £1.7m charge which related to 
provisions for onerous leases and the impairment of fixed 

assets, which were partially offset by a gain on release of 
contingent deferred consideration.  

Adjusted selling, general and administration expenses 
(SG&A) decreased from £13.9m to £13.5m, which 
includes the benefit of improved efficiencies.  Reported 
SG&A decreased from £17.1m to £15.5m. 

Operating profit 

The profit on disposal of fixed assets of £5.2m primarily 
reflects a gain of £4.8m on the establishment of the UK 
JV, in which the Group contributed equipment in return 
for its 50% equity share (see note 4). In addition, other 
unrelated disposals of equipment realised a net gain of 

£0.4m. 

Adjusted operating profit increased by 8% from £17.6m 
to £19.0m, reflecting higher sales and the margin benefit 
from license income. Reported operating profit increased 
3x from £7.2m to £21.2m, which also reflects the 
restructuring charges included in 2014. 

Interest 

Interest costs reduced from £1.9m to £1.8m reflecting 
the reduction in borrowings, and a reduction in the 
imputed (non cash) interest charges relating to the 
discounting of long term balances. 

Tax 

There was a net tax credit of £0.5m in respect of the 
underlying profit, which was consistent with the prior year 

(2014: £0.5m credit).  In addition, there was a £0.3m tax 
credit relating to the exceptional items, compared with a 
tax charge of £3.8m on exceptional items in 2014.  The 
Group has sufficient tax losses available to shield future 
tax payable of circa £37.5m. 

Profit after tax 

Adjusted profit after tax increased by 8% from £16.7m to 

£18.1m, and reported profit after tax increased from 
£2.0m to £20.1m.   The adjusted fully diluted earnings 
per share was 2.60p, up 7% from 2.42p in the prior year. 
Reported diluted earnings per share was 2.90p, up from 
0.24p in 2014.  The Board will not be recommending the 
payment of a dividend. 

Cash flow 

Cash inflow from operations, before exceptional items, 
increased 15% from £19.6m to £22.6m.  After 
exceptional items, cash generated from operations 
increased 41% from £14.9m to £21.0m.

Capital investment 

Debt 

Cash investment was £10.0m up from £9.4m in the prior 

Balance sheet leverage was down £11.6m from £51.9m 

year.  Investment in new product development of £5.0m 
was consistent with the prior year (£5.0m), whilst 
investment in other intangibles was slightly lower at 
£1.2m (2014: £1.3m).   The investment in property, plant 
and equipment increased by £0.6m from £3.2m to 
£3.8m, which remains towards the lower end of the 
normal expected levels of maintenance capex. 

to £40.3m, as gearing reduced from 30% to 22%. This 
reflects that deferred consideration relating to previous 
acquisitions reduced by £3.5m from £20.6m to £17.1m, 
and that net debt reduced by £8.1m from £31.3m to 
£23.2m.  This continues the trend in strong cash 
generation whilst maintaining investment in new 
technologies.

Quality  

Health & Safety 

IQE’s reputation for quality and excellence in products 
and service is second to none. A philosophy of total 

IQE pays a great deal of attention to ensuring the health 
and safety of everyone involved in the business. 

quality is integrated throughout the Group’s operations 
and each of the Group’s manufacturing facilities 
worldwide is independently accredited to the 
international standard for Quality Management: ISO9001.  

IQE's ongoing commitment to providing the highest 
quality of service ensures customer satisfaction covering 
the entire customer relationship experience, from initial 

enquiry through to delivery and after-sales support.  

IQE's quality programme includes wafer evaluation using 
the most advanced measurement techniques applied 
specifically to its customers' structures, thereby ensuring 
consistent delivery of the highest-quality products. 
Rigorous data logging and documentation of all 
manufacturing processes and procedures maintain a 

system of full product traceability. IQE's thorough 
materials characterisation processes ensure excellent 
repeatability and reproducibility.  

Customers strongly value the trust and confidence they 
have established with IQE as a "pure play" supplier with 
whom they share their most confidential and proprietary 

device design information. The IQE strategy is to 
consolidate and maintain its position as the pre-eminent 
supplier of epiwafers rather than vertically integrate into 
device or component manufacturing. This philosophy 
protects customer interests to the fullest and facilitates 
excellent supply chain relationships.  

Employing its extensive wafer production experience, IQE 

continually maintains its technological leadership through 
the development and implementation of new growth and 
characterisation technologies and new materials 
solutions. IQE is actively involved in partnerships with its 
suppliers to develop the next generations of epitaxy and 
metrology equipment with a focus on increasing 
production efficiencies, reducing epiwafer costs, and 

maintaining its technological leadership.  

The environment, health & safety (EHS) group completed 
a restructure at the beginning of 2016, which included 

continuation of training and accreditation of competent 
persons, appointment of safety practitioners whose role 
is to minimise risks of injury at work; ensure legislative 
compliance; and assist in creating and monitoring safety 
practices to be followed. The restructure also included 
the designation of safety advisors, with the appropriate 

expertise to support in specific areas of activity such as 
LEV and pressure systems. 

The EHS group is actively involved in industry-wide 
initiatives and is proactively registering under new 
initiatives such as REACH.  

The EHS group has also recently completed an audit and 
review of chemical control processes to ensure 

continued compliance with HazComm regulations. 

The environment  

IQE is fully committed to creating business growth whilst 
ensuring that the impact on the environment is minimised 
and that all activities are conducted safely by 
appropriately trained and qualified employees. The Group 
works closely with all key stakeholders to ensure that its 

global facilities, and those activities over which it has 
influence through its supply chain, operate in a way that 
is ethical and in accordance with best practice.  

IQE’s policies and procedures are in the process of being 
updated to meet the September 2015 vision of the 
environmental management standard, ISO14001, which 
will be rolled-out across the Group during 2016-17. The 

new standard places a greater emphasis on Risk and 
opportunity management embedded in the organisation. 

Policies relating to quality and environmental standards 
are available on the company’s website at 
www.iqep.com along with access to third party 
accreditation certificates.

Strategic report: principal risks and uncertainties

The Group has an established process for the 
identification and management of risk as part of the 
governance framework. Management of risk is the 
responsibility of the Board of Directors. In managing risk 
a comprehensive and robust system of controls and risk 

management processes have been developed and 
implemented by the board. 

The Board’s role in risk management includes: 

promoting a culture that emphasises integrity at all levels 
of business operations; 

embedding risk management within the core 

processes of the business; 

approving appetite for risk; 

determining the principal risks; 

ensuring that these are communicated effectively 
across the businesses; and, 

setting the overall policies for risk management 
and control. 

The principal risks affecting the Group are identified by 
the Group Executive team within their functional areas of 
responsibility and reviewed by the Board. 

Risk management within the business involves: 

1.

Identification and assessment of individual risks 

2. Design of controls and operational processes to 

mitigate the risks 

3.

Testing of controls through internal review and audits 

4. Conclusion on the effectiveness of the control 

environment in place 

In identifying risks we analyse risks across four key areas: 

strategic risk;  

commercial risk;  

operational risk; and, 

financial risk. 

The principal risks identified are listed in order of severity. 
Mitigation, where possible, is shown by each identified 
risk area.

EU Referendum 

The UK government has announced that there will be a 
referendum on whether the UK should remain in the 
European Union which will be held on the 23rd June 

2016.  

The result on the 23rd of June is unlikely to have any 
significant short term impact on IQE’s business as IQE 
trades both within and external to Europe, with Asia and 
the USA being the Group’s dominant markets and the 
US Dollar being the Groups dominant currency. 

However, as a world leader in advanced semiconductor 

materials, IQE is actively engaged on a number of 
collaborative activities in areas of research and 
development including materials such as graphene. IQE 
has established trading, development partnerships and 
grant funding from across the EU. 

IQE’s position is that continued membership of the EU 
would be the most preferred outcome from the 

forthcoming referendum.  

Continued membership of the EU offers potential longer-
term opportunities for closer collaboration between 
industry, academia and government agencies across 
Europe for the development and commercialisation of 
next generation technologies. The Company’s 
management believe that Europe can play a much larger 

global role in developing and commercialising new and 
emerging technologies that can and will address 21st 
century societal issues. Horizon 2020 and its flagship 
pilot line initiatives (ECSEL), Important Projects of 
Common European Interest, and Photonics 21 are clear 
examples of Europe’s ambition to play a leading role in 

next generation technologies, whilst addressing the 
major societal challenges faced by all economies. 

Innovation and collaboration are vital components in 
developing advanced capabilities and technology 
leadership. Membership of a reformed EU should help 
engender an environment that encourages collaboration 
between companies, academics and government 

agencies across member states, and the UK should play

Statement of directors’ responsibilities 

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 have prepared the group and parent company 
financial statements in accordance with International 
Financial Reporting Standards (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 group and the company and of the profit or 
loss of the group and company for that period.   

In preparing these financial statements, the directors are 
required to: 

select suitable accounting policies and then apply 
them consistently; 

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 the group and enable them to ensure 

that the financial statements and the Directors’ 
Remuneration Report comply with the Companies Act 
2006. They are also responsible for safeguarding the 
assets of the company and the group 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 group’s website, www.iqep.com. 
Legislation in the United Kingdom governing the 
preparation and dissemination of financial statements 
may differ from legislation in other jurisdictions.   

Provision of information to auditors  

So far as the directors are aware, there is no relevant 
audit information of which the company’s auditors are 
unaware.  The directors have taken all the steps that 
ought to have been taken as directors in order to make 
themselves aware of any relevant audit information and 
to establish that the company’s auditors are aware of 

that information.   

Independent Auditors 

A resolution to reappoint PricewaterhouseCoopers LLP 
will be proposed at the forthcoming Annual General 
Meeting. 

Approved by the Board of Directors and signed on behalf 

make judgements and accounting estimates that are 
reasonable and prudent; 

by: 

state whether applicable IFRSs as adopted by the 
European Union have been followed, subject to any 
material departures disclosed and explained in the 
financial statements; 

prepare the financial statements on the going 
concern basis unless it is inappropriate to presume 
that the company will continue in business.

Remuneration report

Introduction 

This report has been prepared applying the principles of 
the disclosures required for quoted companies under the 

Companies Act 2006 which were last amended in 2013 
to introduce enhanced statutory requirements for the 
disclosure of directors’ remuneration. Although not 
required to, the directors have decided to provide some 
of the directors’ remuneration disclosures similar to those 
that would be required of a fully listed company.   In 
particular, the Remuneration Report describes how the 

Board has applied the principles of good governance 
relating to directors’ remuneration adopting the spirit of 
the UK Corporate Governance guidance.  A resolution to 
approve the report will be proposed at the forthcoming 
Annual General Meeting of the company. 

(a) Remuneration Committee 

The Board considers itself ultimately responsible for the 

framework and cost of executive remuneration, but has 
delegated responsibility for determining the remuneration 
levels and conditions of service for executive directors 
and senior executives to the remuneration committee.  
The committee’s approach is fully consistent with the 
company’s overall philosophy that all employees should 

be competitively rewarded in order to attract and retain 
their valued skills in the business, as well as supporting 
corporate strategy by directly aligning executive 
management with the company’s strategic business 
goals.  

The remuneration committee is comprised exclusively of 
independent non-executive directors of the company 

who have no personal financial interest, other than as 
shareholders, in the matters to be decided.  The 
members of the committee throughout the year were Dr 
G H H Ainsworth, Dr D Grant and S J Gibson.   The 
Chairman of the committee is S J Gibson.   

The committee follows the principles of the UK Corporate 
Governance guidance, and is responsible for determining 

the company’s policy on compensation of executive 
directors and the basis of their service agreements with 
due regard to the interests of shareholders.   It also 
approves the allocation of share options to employees.      

The committee operates under clear written terms of 
reference and has access to and takes independent 
professional advice as appropriate.  The committee met 

twice during 2015 to review the performance of the 
executive directors and other senior executives, and set 
the scale and structure of their remuneration.  

(b) Remuneration policy 

In establishing its remuneration policy, the committee has 
given consideration to Schedule B of the Best Practices 
Provisions annexed to the Listing Rules of the Financial 
Conduct Authority. The remuneration packages for 
executive directors and senior executives, as determined 
by the committee, are intended to attract and retain high 
quality executives, induce loyalty and motivate them to 

achieve a high level of corporate performance in line with 
the best interests of shareholders, while not being 
excessive. The remuneration of the executive directors 
consists of annual salary, performance bonus, share 
options, taxable benefits in kind and pension 
contributions. 

There is an annual review at which the committee 

approves the basic salary and profit sharing bonus 
scheme for each executive director. The committee 
receives input from the Chief Executive regarding 
recommended packages for executive directors and 
senior executives. 

(c) Basic salary 

Basic salary is determined by reference to individual 

responsibilities, performance and external market data. 

(d) Performance bonus 

Bonus payments are linked to the executive directors 
achieving internal annual plan targets in respect of 
profitability and other non-financial performance criteria.  
No bonuses were awarded to the directors in respect of 
2015. 

(e) Taxable benefits in kind 

The company reimbursed all fuel and maintenance costs 
in respect of the executive directors’ private cars, and 
these costs are treated as taxable benefits in kind.  Other 
taxable benefits comprise medical health and life 
insurance.

Company No: 3745726  

(f) Share incentive schemes 

The company operates a number of share incentive 
schemes. The IQE Plc Share Option Scheme, as 
adopted on 26 May 2000 and amended by shareholders 

at the company’s Annual General Meeting on 17 May 
2002, allows the company to grant options over up to 
15% of the issued share capital and those options are 
subject to performance conditions.    

During the year, the committee approved the grant of 
540,000 share options to staff (2014: 7,095,762 share 
options). During 2015, No share options were awarded 

to Directors in either 2014 or 2015.  

On 7th January 2016 the Directors were awarded 
17,625,562 deferred shares under the Company’s Long 
Term Incentive Plan (“LTIP”) based on external 
benchmarking. 

As at 31 December 2015, 45,532,098 share options 

(2014: 50,536,520 share options) granted under the IQE 
Plc Share Option Scheme remain outstanding with 
exercise prices ranging from nil cost to 50p/option (2014: 
nil cost to 86p/option).  No share options were exercised 
by directors during the year (2014: 8,541,823 share 
options). None of the directors’ share options lapsed 

during the year (2014: nil). The numbers and prices of 
share options at 31 December 2015 and 31 December 
2014 were as shown in the table below:

Share options of nil cost to 10p/option

Share options in excess of 10p/option to 20p/option

(g) Pension arrangements 

The executive directors are members of the group 
defined contribution pension schemes and their pension 

contributions are based on a percentage of basic annual 
salary.  Their dependants are eligible for the payment of a 
lump sum in the event of death in service.  There have 
been no changes in the terms of directors’ pension 
entitlements during 2015, and there were no unfunded 
pension promises or similar arrangements for directors at 
31 December 2015.  

(h) Executive Directors’ service contracts 

It is the company’s policy to appoint executive directors 
under service agreements which are terminable by either 
party giving between six and twelve months’ notice.   
Each of the agreements contain post-termination 
restrictive covenants, which place limitations on 
solicitation of customers and employees of the group 

and on acting in competition with the business of the 
group.  There are no predetermined provisions for 

compensation on termination within executive directors’ 
service agreements.  However, the company is against 
rewards for failure and believes that severance 

arrangements should be restricted to basic pay and 
consequential payments such as earned bonus. In 
circumstances where there is no conflict of interest, the 
company allows executive directors to serve as non-
executive directors elsewhere. In such circumstances the 
remuneration received is retained by the director. 

(i) Non-Executive Directors’ contracts 

The non-executive directors have entered into service 
agreements with the company, and these are terminable 
by either party on three months’ notice.  Non-executive 
directors have specific terms of engagement, and their 
fees are determined by the Board within the limits set by 
the company’s Articles of Association.   Non-executive 
directors do not take part in discussions on their own 

remuneration.   There were no changes to non-executive 
remuneration during 2015.

Corporate governance report

Although not required to, the directors have decided to 

Dr David Grant is recognised as the senior independent 

provide corporate governance disclosures similar to 
those that would be required of a fully listed company. 

The Board recognises that it is accountable to the 
group’s shareholders for the standard of governance and 
therefore seeks to maintain high standards in its 
management of the affairs of the Group, seeing it as a 
fundamental part of discharging its stewardship 

responsibilities.  Accordingly, both the Board and the 
audit committee continue to keep under review the 
Group’s whole system of internal control, which 
comprises not only financial controls but also operational 
controls, compliance and risk management. 

Throughout the year ended 31 December 2015, the 

company has continued to apply the principles of best 
practice governance adopting the spirit of the UK 
Corporate Governance guidance. 

The Board of Directors 

The management of the group is directed by the Board 
of directors, which is responsible for ensuring the 

development and implementation of the group’s overall 
strategy.   The Board of directors comprises the non-
executive Chairman Dr G H H Ainsworth, the Chief 
Executive Dr A W Nelson, two executive directors and 
two non-executive directors.  There is a clear division of 
responsibility between the non-executive Chairman, who 

is responsible for the running of the Board, and the Chief 
Executive, who is responsible for the running of the 
group in accordance with the authority delegated by the 
Board.  This ensures that there is a balance of power and 
authority such that no one individual has unfettered 
powers of decision.  

The fees of the non-executive directors are paid in cash 

and or shares. The Board considers that the non-
executive directors are independent of management and 
free from any business or other relationship which could 
materially interfere with the exercise of their independent 
judgement.   The terms and conditions of appointment of 
the non-executive directors are available for inspection 
upon request to the Company Secretary.   

non-executive director to whom concerns by staff of any 
suspected impropriety can be conveyed in private and 
investigated as required by the Code of Best Practice.   

Under the Company’s Articles of Association each of the 
directors is required ordinarily to retire by rotation once 
every three years. 

The Board held regular meetings during the year. The 

Board has a formal schedule of matters referred to it for 
decision, which includes the approval of interim and 
annual results, the annual budget, acquisitions and 
disposals, major items of capital expenditure, share 
capital issues, governance issues and executive 
appointments.  The Board is provided with appropriate 

strategic and financial information prior to each meeting 
together with monthly reports to enable it to monitor the 
performance of the group.   The Chief Executive reviews 
the performance of the executive directors on an annual 
basis.  

All directors have direct access to the advice and 
services of the Company Secretary who is responsible 

for ensuring that Board procedures are followed, and are 
allowed to take independent professional advice if 
necessary at the company’s expense.  

Board committees 

The Board has delegated specific responsibilities to the 

following committees: 

(a) Executive Committee 

The executive committee consists of the executive 
directors under the chairmanship of Dr A W Nelson and 
is responsible for the development of strategy, annual 
budgets and operating plans linked to the management 
and control of the day-to-day operations of the group.  

The executive committee is also responsible for 
monitoring key research and development programmes 
and for ensuring that the Board policies are carried out 
on a group-wide basis.

(b) Audit Committee 

(c) Remuneration and Nominations Committees 

The audit committee consists of the non-executive 
directors, Dr G H H Ainsworth, S J Gibson and Dr D 
Grant. The committee meets at least twice a year under 
the chairmanship of Dr G H H Ainsworth.   

The audit committee has specific written terms of 
reference which deal with its authority and responsibilities 
and these are available for inspection upon request to 

the Company Secretary.   Its duties include monitoring 
internal controls throughout the group, approving the 
group’s accounting policies, and reviewing the group’s 
interim results and full year financial statements before 
submission to the full Board.  The audit committee also 
reviews and approves the scope and content of the 
group’s annual risk assessment programme and the 

annual audit, and monitors the independence of the 
external auditors.   

The Group has an Internal Audit function, with a scope of 
evaluating and testing the group’s financial control 
procedures. The Internal Audit function reports directly to 
the chairman of the audit committee, and liaises with the 

external auditors as appropriate.  

The Finance Director, other financial management and 
the external auditors attend meetings of the audit 
committee by invitation.  The committee also holds 
separate meetings with the external auditors, as 
appropriate.

Internal control 

a clearly defined organisational structure and limits of 

The Board acknowledges its responsibility for the group’s 
system of internal control, the effectiveness of which has 
been reviewed by the audit committee during the year 
and reported on to the Board.  The review has taken 
account of any material developments up to the date of 
the signing of the financial statements. 

The processes to identify and manage key risks to the 
success of the group are an integral part of the internal 
control environment. Such processes are on-going, are 
regularly reviewed and improved as necessary, and are in 
accordance with the internal control guidelines for 
directors.  They include strategic planning, the 

appointment of senior executives, the monitoring on a 
regular basis of performance, control of capital 
expenditure and significant revenue investment, and the 
setting of high standards for health, safety and 
environmental performance.  These processes have been 
in place throughout the financial year and up to the date 
of approval of the financial statements. 

The effectiveness of the control systems and procedures 
is monitored regularly through management self-
assessment and review by internal audit.   In addition, 
recognition is given to the external audit findings, which 
inform the audit committee’s views of areas of increased 
risk. 

The system of internal control comprises those controls 

established in order to provide assurance that the assets 
of the group are safeguarded against unauthorised use 
or disposal and to ensure the maintenance of proper 
accounting records and the reliability of financial 
information used within the business or for publication. 
Any system of internal control can only provide 
reasonable, but not absolute, assurance against material 

misstatement or loss, as it is designed to manage rather 
than to eliminate the risk of failing to achieve the business 
objectives of the group. 

The key procedures that the directors have established 
with a view to providing effective internal control are as 
follows: 

authority; 

corporate policies and procedures for financial 
reporting and control, project appraisal, human 
resources, quality control, health and safety, 
information security and corporate governance; 

the preparation of annual budgets and regular 
forecasts which require approval from both the group 

executive committee and the Board; 

the monitoring of performance against budget and 
forecasts and the reporting of any variances in a 
timely manner to the Board; 

regular review and self-assessment of the risks to 
which the group is exposed, taking steps to monitor 
and mitigate these wherever possible including, 

where appropriate, taking out insurance cover; and 

approval by the audit committee of audit plans and, 
on behalf of the Board, receipt of reports on the 
group’s accounting and financial reporting practices 
and its internal controls together with reports from the 
external auditors as part of their normal audit work. 

an internal audit function, which is mandated to 
evaluate and test the Group’s financial control 
procedures, reporting directly to the chairman of the 
audit committee. 

Shareholder relations 

The Chief Executive and the Finance Director meet on a 

regular basis with representatives of institutional 
shareholders to discuss their views and to ensure that 
the strategies and objectives of the group are well 
understood.  The Chief Executive keeps the Board fully 
informed of the views of institutional shareholders.  
Issues discussed with institutional shareholders include 
the group’s performance and the impact of any major 

transactions. The Chairman has met with individual 
shareholders on an ad hoc basis.   

The company also has a manager responsible for 
investor relations and operates a web site, which 
provides details of the group’s facilities and products and 
includes a separate investor relations section on which 

financial data and other significant announcements are 
published. The web site can be found at www.iqep.com.  
The group’s annual report and financial statements, 
interim reports and other documentation is available 
online and by mail where requested.

Company No: 3745726  

The Annual General Meeting allows shareholders to raise 

Audit and related services 

questions with the Board, although shareholder enquiries 
and questions are also addressed throughout the year. In 
accordance with the recommendation of the Hampel 
Code, the company will advise shareholders attending 
the Annual General Meeting of the number of proxy votes 
lodged for each resolution in the categories ‘For’ and 
‘Against’, together with the numbers ‘at the Chairman’s 

discretion’ and abstentions.  These will be advised after 
the resolutions have been dealt with on a show of hands. 

The Board is aware of the importance of maintaining the 
independence of the group auditors, and does not 
contract for additional services from them which would 
compromise their audit independence.  Additional 
services are also subject to appropriate market testing.  

The Audit Committee keeps under review the nature and 

extent of audit and non-audit services provided to the 
group by the auditors in accordance with a policy which 
it established in 2004.  Under this policy, the award to 
the group’s auditors of audit-related services, tax 
consulting services or other non-audit related services in 
excess of £10,000 must first be approved by the 

Chairman of the Audit Committee.  In addition, the 
group’s auditors will be required to make a formal report 
to the Audit Committee annually on the safeguards that 
are in place to maintain their independence and the 
internal safeguards in place to ensure their objectivity. 

The nature of the services provided by the auditors and 
the amounts paid to them (audited) are as detailed 

below:

Company No: 3745726  

Independent auditors’ report to the members of IQE plc

Report on the financial statements 

Our opinion 

In our opinion: 

IQE plc’s group financial statements and parent 
company financial statements (the “financial 
statements”) give a true and fair view of the state of 
the group’s and of the parent company’s affairs as at 

31 December 2015 and of the group’s profit and the 
group’s and the parent company’s cash flows for the 
year then ended; 

the group financial statements have been properly 
prepared in accordance with International Financial 
Reporting Standards (“IFRSs”) as adopted by the 

European Union; 

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. 

What we have audited 

The financial statements, included within the Financial 
Report and Annual Accounts (the “Annual Report”), 
comprise: 

the consolidated and parent company balance sheets 

as at 31 December 2015; 

the consolidated income statement and statement of 
comprehensive income for the year then ended; 

the consolidated and parent company cash flow 
statements for the year then ended; 

the consolidated and parent company statement of 
changes in equity for the year then ended; and 

the notes to the financial statements, which include a 
summary of significant accounting policies and other 
explanatory information. 

Certain required disclosures have been presented 
elsewhere in the Annual Report, rather than in the notes 
to the financial statements. These are cross-referenced 

from the financial statements and are identified as 
audited. 

The financial reporting framework that has been applied 

in the preparation of the financial statements is IFRSs as 
adopted by the European Union, and applicable law and, 
as regards the parent company financial statements, as 
applied in accordance with the provisions of the 
Companies Act 2006. 

In applying the financial reporting framework, the 
directors have made a number of subjective judgements, 

for example in respect of significant accounting 
estimates. In making such estimates, they have made 
assumptions and considered future events. 

Opinion on other matter prescribed by the 
Companies Act 2006 

In our opinion, 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. 

Other matters on which we are required to 
report by exception 

Adequacy of accounting records and information 
and explanations received 

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 no exceptions to report arising from this 
responsibility. 

Directors’ remuneration 

Under the Companies Act 2006 we are required to report 
to you if, in our opinion, certain disclosures of directors’ 

remuneration specified by law are not made. We have no 
exceptions to report arising from this responsibility.  

Page !51

IQE PLC | REPORT AND ANNUAL ACCOUNTS 2015  

Company No: 3745726  

We primarily focus our work in these areas by assessing 
the directors’ judgements against available evidence, 
forming our own judgements, and evaluating the 
disclosures in the financial statements. 

We test and examine information, using sampling and 
other auditing techniques, to the extent we consider 
necessary to provide a reasonable basis for us to draw 

conclusions. We obtain audit evidence through testing 
the effectiveness of controls, substantive procedures or a 
combination of both.  

In addition, we read all the financial and non-financial 
information in the Annual Report to identify material 
inconsistencies with the audited financial statements and 
to identify any information that is apparently materially 

incorrect based on, or materially inconsistent with, the 
knowledge acquired by us in the course of performing 
the audit. If we become aware of any apparent material 
misstatements or inconsistencies we consider the 
implications for our report.

Responsibilities for the financial statements and 

the audit 

Our responsibilities and those of the directors 

As explained more fully in the Statement of directors’ 

responsibilities set out on page 41, the directors are 
responsible for the preparation of the financial statements 
and for being satisfied that they give a true and fair view. 

Our responsibility is to audit and express an opinion on 
the financial statements in accordance with applicable 
law and International Standards on Auditing (UK and 
Ireland) (“ISAs (UK & Ireland)”). Those standards require 

us to comply with the Auditing Practices Board’s Ethical 
Standards for Auditors. 

This report, including the opinions, has been prepared for 
and only for the parent company’s members as a body in 
accordance with Chapter 3 of Part 16 of the Companies 
Act 2006 and for no other purpose. We do not, in giving 
these opinions, accept or assume responsibility for any 

other purpose or to any other person to whom this report 
is shown or into whose hands it may come save where 
expressly agreed by our prior consent in writing. 

What an audit of financial statements involves 

We conducted our audit in accordance with ISAs (UK & 
Ireland). An audit involves obtaining evidence about the 
amounts and disclosures in the financial statements 

sufficient to give reasonable assurance that the financial 
statements are free from material misstatement, whether 
caused by fraud or error. This includes an assessment of:  

whether the accounting policies are appropriate to the 
group’s and the parent company’s circumstances and 
have been consistently applied and adequately 

disclosed;  

the reasonableness of significant accounting estimates 
made by the directors; and 

the overall presentation of the financial statements.

Notes to the financial statements

1 - Significant accounting policies 
The principal accounting policies adopted in the preparation of these financial statements are set out below.  These policies have been 
consistently applied to all years presented. 

General Information 

IQE plc Group’s principal activity are set out on page 40 of the directors report. The company is a public limited company, which is 
listed on the Alternative Investment Market (AIM) and incorporated and domiciled in England and Wales. The address of its registered 
office is Pascal Close, St Mellons, Cardiff, CF3 0LW. 

Basis of preparation 

This financial information has been prepared on a going concern basis under the historical cost convention except where fair value 
measurement is required by IFRS, and in accordance with the Companies Act 2006 applicable to companies reporting under IFRS, 
International Financial Reporting Standards (“IFRS”) as adopted by the European Union and IFRS IC interpretations.  The application of 
these standards and interpretations necessitates the use of estimates and judgements.  The main areas involving estimates are set out 
below in note 2.  

Changes in accounting policy and disclosures 

(a) New standards, amendments and interpretations adopted by the group. The following standards have been adopted by the group 
for the first time for the financial year beginning on or after 1 January 2015. They do not materially impact on the group results:  

• Annual improvements 2011 - 2013 

(b) New standards, amendments and interpretations issued but not effective for the financial year beginning 1 January 2015 and not 

early adopted 

A number of new standards and amendments to standards and interpretations have been endorsed for annual periods beginning after 
1 January 2015 (noted below), and have not been early adopted in preparing these consolidated financial statements. None of these 
are expected to have a significant effect on the consolidated financial statements of the group. 

• Annual improvements 2014 (2012-2014 cycle)  

• Amendment to IFRS 11, 'Joint arrangements' on acquisition of an interest in a joint operation  

• Amendments to IAS 16, 'Property, plant and equipment'  

• Amendments to IAS 27, 'Separate financial statements' on the equity method  

• Amendment to IAS 1, 'Presentation of financial statements' on the disclosure initiative  

• Amendment to IFRS 10, 11 and 12 on transition guidance  

• Amendments to IAS 32 and IFRS 7 Financial instruments on asset and liability offsetting  

• IAS 28 (revised), 'Investments in associates and joint ventures'  

• IFRS 13, 'Fair value measurement'   

• Amendment to IAS 12,'Income taxes' on deferred tax  

• Amendment to IAS 16, 'Property, plant and equipment' and IAS 38,'Intangible assets', on depreciation and amortisation  

• Amendment to IAS 36, 'Impairment of assets' on recoverable amount disclosures. 

A number of new standards and amendments to standards and interpretations have been issued but are not yet endorsed for annual 
periods beginning after 1 January 2015 (noted below), and have not been adopted in preparing these consolidated financial 
statements. None of these are expected to have a significant effect on the consolidated financial statements of the group. 

IFRS 15 Revenue from contracts with customers (effective for annual periods beginning on or after 1 January 2018) 

IFRS 9 Financial instruments (effective for annual periods beginning on or after 1 January 2018) 

Basis of consolidation 

The consolidated financial statements incorporate the financial statements of the company and its subsidiary undertakings.  
Subsidiaries are all entities over which the Group has control. The Group controls an entity when the Group is exposed to, or has rights 
to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity.  

Subsidiaries are fully consolidated from the date on which control is transferred to the Group and are de-consolidated from the date 
that control ceases.   

Inter-company transactions, balances, income and expenses on transactions between group companies are eliminated. Profits and 
losses resulting from intercompany transactions that are recognised in assets are also eliminated. Accounting policies of subsidiaries 
have been changed where necessary to ensure consistency with the policies adopted by the group.

Page !60

IQE PLC | REPORT AND ANNUAL ACCOUNTS 2015  

Company No: 3745726  

Joint ventures 

The group applies IFRS 11 to all joint arrangements. Under IFRS 11 investments in joint arrangements are classified as either joint 
operations or joint ventures depending on the contractual rights and obligations each investor. We have assessed the nature of our joint 
arrangements and determined them to be joint ventures. Joint ventures are accounted for using the equity method.  

Under the equity method of accounting, interests in joint ventures are initially recognised at cost and adjusted thereafter to recognise 
the group’s share of the post-acquisition profits or losses and movements in other comprehensive income. When the group’s share of 
losses in a joint venture equals or exceeds its interests in the joint ventures (which includes any long term interests that, in substance, 
form part of the group’s net investment in the joint ventures), the group does not recognise further losses, unless it has incurred 
obligations or made payments on behalf of the joint ventures.  

Unrealised gains on transactions between the group and its joint ventures are eliminated to the extent of the group’s interest in the joint 
ventures. Unrealised losses are also eliminated unless the transaction provides evidence of an impairment of the asset transferred. 
Accounting policies of the joint ventures have been changed where necessary to ensure consistency with the policies adopted by the 
group. 

Business combinations 

The acquisition of subsidiaries is accounted for using the purchase method.  The cost of an acquisition is measured at the fair value of 
the consideration. The acquired identifiable assets, liabilities and contingent liabilities are recognised at their fair value at the date of 
acquisition.  

Where the fair values of contingent deferred consideration, assets and liabilities acquired are initially recognised on a provisional basis, 
these are reassessed during the 12 month period following the date of the business combination. Adjustments to the fair values as at 
the date of acquisition within this ‘measurement period’ are recorded, with any net impact being added to or deducted from the 
goodwill recognised. Such adjustments are recognised in both the current period and restated comparative period balance sheets as if 
the final fair values had been used in the initial recognition of the acquisition. 

Subsequent to the measurement period, any adjustments to the recorded fair value of contingent deferred consideration are taken 
through the income statement as an exceptional income or expense. 

The group recognises any non-controlling interest on an acquisition-by-acquisition basis, either at fair value or at the non-controlling 
interest’s proportionate share of the recognised amounts of acquiree’s identifiable net assets. 

Acquisition related costs are expensed as incurred. 

Intangible assets 

(a) Goodwill 

Goodwill arising on an acquisition is recognised as an asset and initially measured at cost, being the excess of the fair value of the 
consideration over the fair value of the identifiable assets, liabilities and contingent liabilities acquired. 

Goodwill is not amortised. However, it is reviewed for potential impairment at least annually or more frequently if events or 
circumstances indicate a potential impairment.  For the purpose of impairment testing, goodwill is allocated to each of the Cash 
Generating Units to which is relates. Any impairment identified is charged directly to Consolidated Income Statement.  Subsequent 
reversals of impairment losses for goodwill are not recognised. 

(b) Patents trademarks and licences 

Separately acquired patents, trademarks and licences are shown at historical cost. Patents, trademarks and licences acquired in a 
business combination are recognised at fair value at the acquisition date. Patents, Trademarks and licences have a finite useful life and 
are carried at cost less accumulated amortisation. Amortisation is calculated using the straight-line method to allocate the cost of 
trademarks and licences over their estimated useful lives of 10 to 15 years.    

The carrying value of patents, trademarks and licences is reviewed for potential impairment at least annually, or more frequently if 
events or circumstances indicate a potential impairment.  Any impairment identified is immediately charged to the Consolidated Income 
Statement.

Company No: 3745726  

(c) Development costs 

Expenditure incurred that is directly attributable to the development of new or substantially improved products or processes is 
recognised as an intangible asset when the following criteria are met: 

• the product or process is intended for use or sale; 

• the development is technically feasible to complete; 

• there is an ability to use or sell the product or process; 

• it can be demonstrated how the product or process will generate probable future economic benefits; 

• there are adequate technical, financial and other resources to complete the development; and 

• the development expenditure can be reliably measured. Directly attributable costs refers to the materials consumed; the directly 
attributable labour; and the incremental overheads incurred in the development activity.  General operating costs, administration 
costs and selling costs do not form part of directly attributable costs.      

All research and other development costs are expensed as incurred. 

Capitalised development costs are amortised in-line with the expected revenue profile over the period during which the economic 
benefits are expected to be received, which typically range between 3 and 8 years.  The estimated remaining useful lives of 
development costs are reviewed at least on an annual basis. Amortisation commences once the project is completed and revenues are 
being generated. 

The carrying value of capitalised development costs is reviewed for potential impairment at least annually, or more frequently if events or 
circumstances indicate a potential impairment.  Any impairment identified is immediately charged to the Consolidated Income 
Statement. 

(d) Software 

Directly attributable costs incurred in the development of bespoke software for the group’s own use are capitalised and amortised on a 
straight line basis over the expected useful life of the software, which typically range between 3 and 8 years.   

The carrying value of capitalised software costs is reviewed for potential impairment at least annually, or more frequently if events or 
circumstances indicate a potential impairment. Any impairment identified is immediately charged to the Consolidated Income 
Statement.  

The costs of maintaining internally developed software, and annual license fees to utilise third party software, are expensed as incurred.  

(e) Other intangibles recognised on acquisition 

Other intangible assets which form part of the identifiable net assets of an acquired business are recognised at their fair value and 
amortised on a systematic basis over their useful economic life which is up to 7 years. 

This includes customer contracts, the fair value of which has been evaluated using the multi period excess earnings method “MEEM”. 
The MEEM model valuation was cross checked to the cost of product development and qualification to which the contract relates. 

The carrying value of other intangible assets is reviewed for potential impairment at least annually, or more frequently if events or 
circumstances indicate a potential impairment.  Any impairment identified is immediately charged to the Consolidated Income 
Statement. 

Property, plant and equipment 

Property, plant and equipment is stated at cost less accumulated depreciation and any provision for impairment. Cost comprises all 
costs that are directly attributable to bringing the asset into working condition for its intended use. Depreciation is calculated to write 
down the cost of fixed assets to their residual values on a straight-line basis over the following estimated useful economic lives: 

..................................

Freehold buildings	
Short leasehold improvements	
Plant and machinery	
Fixtures and fittings	

..................
.................................
.....................................

15 to 25 years

5 to 27 years

5 to 15 years

3 to 5 years 

No depreciation is provided on land or assets yet to be brought into use. 

The assets residual values and useful economic lives are reviewed, and adjusted if appropriate, at the end of each reporting period. The 
carrying value of property, plant and equipment is reviewed for potential impairment at least annually.  Any impairment identified is 
immediately charged to the Consolidated Income Statement. 

Impairment of non-current assets 

Non-current assets are reviewed for potential impairment at least annually, or more frequently if events or circumstances indicate a 
potential impairment.  An impairment loss is recognised for the amount by which the asset’s carrying amount exceeds its recoverable 
amount.  The recoverable amount is the higher of an asset’s fair value (less disposal costs) and value in use. 

Value in use is based on the present value of the future cash flows relating to the asset, discounted at the Group’s weighted average 
cost of capital.  For the purpose of assessing impairment, assets are grouped at the lowest levels for which there are separately 
identifiable cash flows (Cash Generating Units).

IQE PLC | REPORT AND ANNUAL ACCOUNTS 2015  

Company No: 3745726  

Inventories 

Inventories are stated at the lower of cost and net realisable value.  Cost is determined using the first-in, first-out (FIFO) method. Cost 
comprises direct materials and, where applicable, direct labour costs and attributable overheads that have been incurred in bringing the 
inventories to their present location and condition based on normal operating capacity. Net realisable value is the estimated selling price 
in the ordinary course of business, less applicable variable selling expenses. 

Trade receivables 

Trade receivables are amounts due from customers for merchandise sold or services performed in the ordinary course of business. If 
collection is expected in one year or less (or in the normal operating cycle of the business if longer), they are classified as current 
assets. If not, they are presented as non-current assets. 

Trade receivables are recognised initially at fair value and subsequently measured at amortised cost using the effective interest method, 
less provision for impairment. 

Cash and cash equivalents 

In the consolidated statement of cash flows, cash and cash equivalents includes cash in hand, deposits held at call with banks, other 
short-term highly liquid investments with original maturities of three months or less and bank overdrafts. In the consolidated and parent 
company balance sheet, bank overdrafts are shown within borrowings in current liabilities. 

Trade payables 

Trade payables are obligations to pay for goods or services that have been acquired in the ordinary course of business from suppliers. 
Accounts payable are classified as current liabilities if payment is due within one year or less (or in the normal operating cycle of the 
business if longer). If not, they are presented as non-current liabilities.  

Trade payables are recognised initially at fair value and subsequently measured at amortised cost using the effective interest method. 

Provisions 

Provisions are recognised when: 

• the Group has a legal or constructive obligation as a result of a past event; 

• it is probable that an outflow of resources will be required to settle the obligation and the amount has been reliably estimated. 

Provisions are measured at the present value of the expenditures expected to be required to settle the obligation. Where a leasehold 
property, or part thereof, is vacant or sub-let under terms such that the rental income is insufficient to meet all outgoings, provision is 
made for the anticipated future shortfall up to termination of the lease, or the termination payment, if smaller. 

Financial instruments 

Financial assets and liabilities are recognised on the group’s balance sheet when the group becomes a party to the contractual 
provisions of the financial instrument. 

The financial assets held by the group are other equity investments, receivables and cash and cash equivalents. Receivables do not 
carry interest and are stated at their nominal value as reduced by appropriate allowances for estimated irrecoverable amounts. Cash 
and cash equivalent comprise cash in hand. Other equity investments are held at cost less provision for impairment. 

Financial liabilities and equity instruments are classified according to the substance of the contractual arrangements entered into. An 
equity instrument is any contract that evidences a residual interest in the assets of the Group after deducting all of its liabilities. Trade 
payables are stated at their nominal value and do not bear interest. 

Equity instruments issued by the company are recorded at the proceeds received net of any direct issue costs. 

Interest bearing loans are recorded at the proceeds received net of any direct issue costs. Finance charges are accounted for on an 
accrual basis using the effective interest method. 

The group does not use derivative financial instruments for speculative purposes.  The group uses forward currency contracts as 
appropriate to manage foreign exchange risk. 

Detailed disclosures of the group’s financial instruments are provided in note 19. 

Leases 

Leases which transfer substantially all the risks and rewards of ownership of an asset are treated as a finance lease.  Assets held under 
finance leases are capitalised at their fair value at the inception of the lease and depreciated over the  estimated useful economic life of 
the asset or lease term if shorter.  The finance charges are allocated to the Consolidated Income Statement in proportion to the capital 
amount outstanding. 

All other leases are classified as operating leases. Operating lease rentals are charged to the Consolidated Income Statement in equal 
annual amounts over the lease term.

Revenue recognition 

Revenue represents the amounts receivable for goods, services and intellectual property licenses provided in the ordinary course of 
business net of value added tax and other sales related taxes. Revenue is recognised when the risks and rewards of the underlying sale 
have been transferred to the customer, which is on the delivery of the goods, services or intellectual property and acceptance by the 
customer. 

Accrued income is recognised for sales where, at the balance sheet date, billing has not yet taken place but contractual terms dictate 
that the risks and rewards have been transferred to the customer and the customer is committed to payment. Billing is deferred to a 
contractually defined trigger point. 

An acquisition was made during 2012, where the consideration is being settled through agreed contractual price discounts. 
Subsequent to the measurement period, any adjustments to the recorded fair value of contingent deferred consideration are taken 
through the income statement within other income as an exceptional income or expense. The revenues of products sold which are 
subject to this discount are recognised at full market value. On settlement of the transaction, the discount is applied to reduce the 
deferred consideration balance.  

Segmental reporting 

Operating segments are reported in a manner consistent with the internal reporting provided to the Board of Directors, who oversee the 
allocation of resources and the assessment of operating segment performance. 

A geographical segment is engaged in providing products or services within a particular economic environment that are subject to risks 
and returns that are different from those of components operating in other economic environments. 

Pension costs 

The group operates defined contribution pension schemes.  Contributions are charged in the Consolidated Income Statement as they 
become payable in accordance with the rules of the scheme.  

Share based payments 

The group operates a Share Option Scheme, under which the group receives services from employees as consideration for share 
options in IQE plc.  The fair value of the employee services received in exchange for the grant of the options is recognised as an 
expense in the Consolidated Income Statement. The total amount to be expensed is determined by reference to the fair value of the 
options granted including any market performance conditions (for example, an entity's share price); excluding the impact of any service 
and non-market performance vesting conditions (for example, profitability, sales growth targets and remaining an employee of the entity 
over a specified time period) and including the impact of any non-vesting conditions (for example, the requirement for employees to 
save). 

Non-market performance and service conditions are included in assumptions about the number of options that are expected to vest. 
The total expense is recognised over the vesting period, which is the period over which all of the specified vesting conditions are to be 
satisfied. At the end of each reporting period, the group revises its estimates of the number of options that are expected to vest based 
on the non-market vesting conditions. It recognises the impact of the revision to original estimates, if any, in the income statement, with 
a corresponding adjustment to equity. 

When the options are exercised, the company issues new shares. The proceeds received net of any directly attributable transaction 
costs are credited to share capital (nominal value) and share premium. The scheme is equity settled. 

In the company’s own financial statements, the grant of share options to the employees of subsidiary undertakings is treated as a 
capital contribution. Specifically, the fair value of employee services received (measured at the date of grant) is recognised over the 
vesting period as an increase to investment in subsidiary undertakings, with a corresponding credit to equity in the parent entity 
financial statements. 

The social security contributions payable in connection with the grant of the share options is considered an integral part of the grant 
itself, and the change will be treated as a cash-settled transaction. 

Exceptional items 

Exceptional items are disclosed separately in the financial statements where it is necessary to do so to provide further understanding of 
the financial performance of the group. They are material items of income or expense that have been shown separately due to the 
significance of their nature or amount. Details of the exceptional items are included in note 4.

Foreign currencies 

Items included in the financial statements of each subsidiary are measured using the currency of the primary economic environment in 
which the subsidiary operates (“the functional currency”).  The consolidated financial statements are presented in sterling, which is the 
group’s presentational currency. 

Foreign currency transactions are translated into the subsidiaries functional currency at the rates of exchange ruling at the date of the 
transaction, or at the forward currency hedged rate where appropriate.  Monetary assets and liabilities in foreign currencies are 
translated into the subsidiaries functional currency at the rates ruling at the balance sheet date.  All exchange differences are taken to 
the income statement. 

The balance sheets of overseas subsidiaries are translated into sterling at the closing rates of exchange at the balance sheet date, 
whilst the income statements are translated into sterling at the average rate for the period.  The resulting translation differences are 
taken directly to reserves. 

Foreign exchange gains and losses on the retranslation of foreign currency borrowings that are used to finance overseas operations are 
accounted for on the ‘net investment’ basis and are recorded directly in reserves provided that the hedge is ‘effective’ as defined in IAS 
39 “Financial Instruments: recognition and measurement”. 

Taxation 

Income tax on the profit or loss for the year comprises current and deferred tax. 

Current tax is the expected tax payable on the taxable income for the year using rates substantially enacted at the balance sheet date, 
and any adjustments to tax payable in respect of prior years. 

Amounts receivable from tax authorities in relation to R&D tax relief claims for fiscal year 2013 and before are recognised as a credit 
within the group's tax charge. For subsequent years the R&D tax credits are under the RDEC scheme and are recognised with 
operating profit. 

Where amounts are outstanding at the year end and have not been formally agreed, an appropriate estimate of the amount is included 
within other receivables. 

Deferred tax is provided in full on temporary differences between the carrying amounts of assets and liabilities in the financial 
statements and the amounts used for taxation purposes. Deferred tax is calculated at the tax rates that have been enacted or 
substantially enacted at the balance sheet date.  Deferred tax assets are only recognised to the extent that it is probable that future 
taxable profits will be available against which deductible temporary differences can be utilised. Deferred tax liabilities are recognised for 
taxable temporary differences, unless specifically exempt.  

Deferred tax assets and liabilities are offset when there is a legally enforceable right to set off current taxation assets against current 
taxation liabilities and it is the intention to settle these on a net basis.   

Tax is recognised in the Consolidated Income Statement except to the extent that it relates to items recognised directly in equity, in 
which case it is recognised in equity. 

Investment in subsidiaries  

Investments in subsidiaries are held at cost of investment less provision for impairment in the parent company financial statements. 

Other equity investments 

Other equity investments are held at cost less provision for impairment in both the parent company and group financial statements on 
the basis that the Group (and Company) does not have the ability to exert significant influence or control over the strategic and 
operating activities of the other equity investments.

2 - Critical accounting judgements and key sources of estimation uncertainty 

The group’s principal accounting policies are described in note 1.  The application of these policies necessitates the use of estimates 
and judgements in a number of areas.  Accordingly, the actual amounts may differ from these estimates.  The main areas involving 
estimation are set out below: 

(a) Impairment of tangible and intangible assets 

Goodwill on the group’s balance sheet is not subject to amortisation because it is assumed to have an indefinite useful life.   In 
accordance with IAS 36 “Impairment of assets”, the carrying value of goodwill is assessed at least annually for impairment.   This 
assessment is based on cash flow forecasts.   In light of these forecasts the Board has concluded that goodwill is not impaired. 

The group capitalises the cost of developing new and substantially improved products and processes if there is a reasonable 
expectation of obtaining an appropriate economic return.  This necessitates an assessment of the future technical viability, future 
commercial benefits and expected useful economic life of the product or process.  The carrying value for each project is assessed for 
impairment on an on-going basis. 

The key assumptions and judgements adopted in preparing the impairment review are set out in note 11. 

(b) Impairment of receivables 

Trade and other receivables are carried at the contractual amount due less any estimated provision for non-recovery.   Provision is 
made based a number of factors including the age of the receivable, previous collection experience and the financial circumstances of 
the counterparty.   

(c) Inventory provisions 

Inventories are carried at the lower of cost and net realisable value.  Provision is made based on a number of factors including the age 
of inventories, the risk of obsolescence and the expected future usage.  

(d) Acquisition fair values 

An assessment of the fair value of the purchase consideration and net assets acquired was undertaken for the acquisitions made 
during 2012 and 2013.  We have reassessed the fair value of the deferred contingent consideration in relation to the 2012 RFMD 
acquisition. This resulted in an exceptional release of £0.8m (2014: £9.9m) to other income as a result of the re-assessment of the 
forecast volumes. Further details are provided in note 4. 

(e) Deferred tax assets 

Deferred tax assets are only recognised to the extent that it is probable that future taxable profits will be available against which 
deductible temporary differences can be utilised. This necessitates an assessment of future trading forecasts for each relevant tax 
authority, capital expenditures and the utilisation of tax losses.  

The forecasts used to support deferred tax asset recognition are the same forecasts used in the impairment review and support partial 
recognition of the available deferred tax assets. 

(f) Onerous lease provision 

A provision for onerous leases was made in the prior year. The provision assumes that the lease will be onerous for the next three and a 
half years. Subsequent to this period we expect to be able to sublet the premises or negotiate to exit the lease. The full term of the 
lease obligation is 6 years with the lease running until 2021. 

(g) Adjustments to profit 

The board provides an adjusted profit measure to provided additional information to aid an understanding of the group’s performance 
as set out in note 4 we have detailed all of the items which are included within the adjustments to profit.

* The profit arising from license income sales to joint ventures represents revenue of £15,310,000 offset by an elimination of unrealised 
profit of £7,286,000 relating to our retained interest in the Compound Semiconductor Centre Limited joint venture. 

Costs not directly attributable to a segment are allocated based on the proportion of revenue attributable to that segment. 

Staff work for multiple segments, therefore it is not possible to allocate staff related expenses and the share based payment charge to 
specific segments.  

Finance costs are not allocated to the segments because treasury is managed centrally. 

Measures of total assets and liabilities for each reportable segment are not reported to the chief operating decision maker and therefore 
have not been disclosed.

As disclosed in note 27, in July 2015 the group established a joint venture with Cardiff University to develop and commercialise 
compound semiconductor technologies in Europe.  To establish the joint venture, IQE contributed equipment with a market value of 
£12m, which was matched by a £12m cash contribution from Cardiff University.  This created a non-cash exceptional gain of £4.8m in 
IQE’s accounts reflecting the Group’s share of the difference between the book value and market value of the equipment contributed.   
In addition, other unrelated disposals of fixed assets realised a net gain of £0.4m. 

The non-cash accounting charges of £3.6m (2014 : £3.1m) reflect a charge for share based payments of £2.0m (2014 £1.5m), the 
amortisation of acquired intangibles £1.2m (2014 £1.1m) and the unwind of the discounting of long term balances £0.4m (2014 
£0.5m). 

The Group generated a non-cash profit of £0.8m (2014 £9.9m) arising from a reduction in the estimated remaining deferred 
consideration (settled via trade discount) in respect of a previous acquisition. This has been classified within other income and 
expenses in the consolidated income statement. 

The restructuring and reorganisation costs of £0.6m (2014: £17.8m) reflects some one-off redundancy and asset write downs 
associated with the restructuring of the groups manufacturing operations.  

The deferred tax credit of £0.3m (2014: £3.8m charge) reflects the net deferred tax impact associated with these adjustments. 

Certain items noted above are accounting estimates based on judgements, accordingly, the actual amounts may differ from these 
estimates. The adjustments above are classified £1.8m (2014: £5.6m) within gross margin, and £2.0m (2014: £3.2m) within sales 
general & admin costs.

Finance (No.2) Act 2015, which was substantively enacted on 26 October 2015, included legislation to reduce the main rate of 
corporation tax from 20% to 19% from 1 April 2017 with a further reduction to 18% from 1 April 2020. Accordingly, the closing UK 
deferred tax asset/liability in the financial statements has been recognised on this basis. 

Deferred tax is measured at the tax rates that are expected to apply in the relevant territory in the period when the asset is realised or 
the liability is settled, based on tax rates and tax laws that have been substantively enacted at the balance sheet date. 

The majority of the deferred tax assets arise in the United States, these are provided at the effective United States Federal and State tax 
rates where appropriate.

8 - Taxation (continued) 

Deferred tax assets are recognised for tax losses carried forward to the extent that the realisation of the related tax benefit through 
future taxable profits from the same trade is probable.  

The net amount not recognised is an asset of £10,808,000 (2014: £19,595,000). The unrecognised amounts relate to tax losses 
carried forward. The asset would be recognised if sufficient profits from the same trade arise in future periods. 

Total tax losses carried forward account for a potential deferred tax asset of £37,469,000 (2014: £39,076,000). 

Company 

There is an unrecognised deferred tax asset of £522,000 (2014: £585,000) which relates primarily to short term timing differences 
arising on share option charges.  

R&D Tax Credits 

The Group recognised a credit of £537,000 (2014: £925,000) within operating profit in relation to claims made under the R&D 
Expenditure Credit Scheme (RDEC).  

9 - Dividends 

No dividend has been paid or proposed in 2015 (2014: £nil). 

10 - Earnings per share 

Basic earnings per share is calculated by dividing the profit attributable to ordinary shareholders by the weighted average number of 
ordinary shares in issue during the year.   

Diluted earnings per share is calculated by dividing the profit attributable to ordinary shareholders by the weighted average number of 
shares and the dilutive effect of ‘in the money’ share options in issue. Share options are classified as ‘in the money’ if their exercise 
price is lower than the average share price for the year. As required by IAS 33, this calculation assumes that the proceeds receivable 
from the exercise of ‘in the money’ options would be used to purchase shares in the open market in order to reduce the number of new 
shares that would need to be issued.   

The directors also present an adjusted earnings per share measure which eliminates certain non-cash items in order to provide a more 
meaningful underlying profit measure.  The adjustments are detailed in note 4.

11 - Intangible assets (continued) 

The amortisation charge of: £5,040,000 (2014: £3,902,000) has been charged to selling, general and administrative expenses in the 
Consolidated Income Statement. 

The carrying value of deferred development costs continue to be supported by forecast cash flows.  

Impairment tests for goodwill 

Goodwill is tested for impairment annually and whenever there is an indication of impairment at the level of the cash-generating unit 
(CGU) or group of CGUs to which it is allocated. Multiple production facilities are included in a single CGU reflecting that production can 
(and is) transferred between sites for different operating segments to suit capacity planning and operational efficiency. Given the 
interdependency of facilities, goodwill is therefore tested for impairment by grouping operational sites into a CGU or CGUs based on 
type of production. This gives rise to the following allocation of Goodwill:

57,853

2014 
£’000

49,694

6,161

55,885

The recoverable amount of the CGUs has been determined based on value in use calculations, using cash flow projections for a five 
year period plus a terminal value. The Board approved budget is used for the first year of the forecast.   

Key assumptions applied in the forecasts include: 

• Margin erosion 1.5% pa (2014: 1% pa),  

• Cost inflation 2% (2014: 3% pa),   

• A long term growth rate of 2% (2014: n/a) 

• A discount rate of 9% (2014: 11%) 

Management believes it is appropriate to use the same discount rate for each CGU given that they have similar risk profiles and 
common funding.  

In respect of the III/V Epitaxy CGU, the forecast EBITDA compound growth rate is c.6% over the five year period. Driving this growth is 
Photonics revenue growth of c.10.5% pa (2014: 10.5% pa) which is significantly lower than the 2015 Photonics revenue growth rate. 
Also included is revenue into emerging markets growing to c.£23m after 5 years (2014: £10m after 5 years). 

No impairment would arise if the EBITDA compound growth rate fell to zero over the same period. An impairment of the III/V Epitaxy 
CGU goodwill would arise in the event that the discount rate was increased from 9% to 13%.

During 2014 as part of the rationalisation and re-organisation programme, IQE provided facilities, equipment and IP on favourable terms 
to the CSDC.  As a consequence, IQE booked provisions of £4.9m for asset impairment relating to the transfer of tools to the CSDC. 
The impairment provision wrote the assets down to their recoverable amount. 

*As part of the ongoing standardisation and improvement of the group underlying accounting records, accumulated cost and 
depreciation of £29.5m were eliminated in respect of fully depreciated assets no longer used within the business.

Details of the company’s subsidiaries are set out in note 26. 

Investments are reviewed for impairment annually, where the net asset value is lower than the investment carrying value an impairment 
charge is recognised in the income statement.  

During 2014 impairment charges of £1,076,000 were recognised to the write down of the investment in subsidiaries to recoverable 
amount.

As at 31 December 2015, 82% (2014: 88%) of trade receivables were within terms.  Of the other trade receivables, 64% (2014: 93%) 
were less than 30 days past due.  An allowance has been made for estimated irrecoverable amounts from the sale of goods of 
£204,000 (2014: £330,000).  This allowance has been determined by reference to past default experience. Included in other 
receivables is accrued income of £7,739,000 (2014: £8,806,000). 

Our trade receivables are with established customers, we monitor customer D&B credit ratings and have had no material defaults in the 
past. None of our receivables are with customers where we have had any history of default.  

The maximum exposure to credit risk at the reporting date is the carrying value of each class of receivable as set out above.  In terms 
of trade receivables, the terms of sale provide that the group has recourse to the products sold in the event of non-payment by a 
customer. 

Amounts owed by group undertakings are unsecured and repayable on demand. Interest is charged at a rate of 5% per annum (2014: 
5% per annum). 

Financial assets relate to £8,000,000 of Preferred ‘A’ shares (2014: £nil) issued by Compound Semiconductor Centre Limited (‘CSC’), a 
joint venture between the Group and Cardiff University (see Note: 27 for further details. The preference shares carry the following rights: 

• No voting rights 

• Dividend equivalent to the HSBC Bank PLC base rate for the applicable period on the amount paid up, subject to CSC having 

available profits. 

• Repayable in proportion to the outstanding principle from surplus cash generated.  

The carrying values of trade and other receivables also represent their estimated fair values.

Within deferred consideration is £5.6m (2014: £10.7m) being the best estimate of the amount that will be settled through contractually 
agreed price discounts over the next year (2014: two years). Long term contingent deferred consideration balances are discounted at 
2.5%. 

The fair value of the contingent deferred consideration has been re-assessed during the year resulting in a reduction of £0.8m (2014: 
£9.9m). This has been credited to the consolidated income statement within other income and expenses. The exceptional income has 
been excluded from our adjusted profit measure set out in note 4. 

Amounts owed to group undertakings are unsecured and repayable on demand. Interest is charged at a rate of 5% per annum (2014: 
5% per annum). 

The carrying values of trade and other payables also represent their estimated fair values. 

There are no foreign currency exchange contracts held at 31 December 2015 or 31 December 2014.

During 2014, as part of the re-organisation and rationalisation of the Group’s facilities the Group is ceased activities at its Singapore 
facility and established the Compound Semiconductor Development Centre. The provision above represents the onerous lease 
obligation in respect of the Singapore property. This is expected to be utilised over the next three and a half years. The provision has 
been discounted using a risk free rate of 2.5%. 

19 - Financial instruments 

Financial instruments by category 

Trade and other receivables (excluding prepayments), preference share receivables and cash and cash equivalents are classified as 
'loans and receivables'. Borrowings and trade and other payables are classified as 'other financial liabilities at amortised cost'. Both 
categories are initially measured at fair value and subsequently held at amortised cost. 

Derivatives (forward exchange contracts) are classified as 'derivatives used for hedging' and accounted for at fair value with gains and 
losses taken to reserves through the consolidated statement of comprehensive income. 

Financial risk and treasury policies 

The Group's finance team maintains liquidity, manages relations with the Group’s bankers, identifies and manages foreign exchange risk 
and provides a treasury service to the Group’s businesses. Treasury dealings such as investments, borrowings and foreign exchange 
are conducted only to support underlying business transactions. 

The Group has clearly defined policies for the management of foreign exchange rate risk. The Group finance team does not undertake 
speculative foreign exchange dealings for which there is no underlying exposure. Exposures resulting from sales and purchases in 
foreign currency are matched where possible and the net exposure may be hedged by the use of forward exchange contracts.

Credit risk 

Credit risk is the risk of financial loss to the Group if a customer or counterparty to a financial instrument fails to meet its contractual 
obligations, and arises principally from the Group’s receivables from customers and monies on deposit with financial institutions 

Where the group assesses a potential credit risk, this is dealt with either by up-front payment prior to the shipment of goods or by other 
credit risk mitigation measures. As a result the group has historically had and continues to have a very low level of payment default. 

The maximum exposure to credit risk at the reporting date is the carrying value of each class of receivable as set out below.  In terms of 
trade receivables, the terms of sale provide that the group has recourse to the products sold in the event of non-payment by a 
customer.

Included in other receivables is accrued income of £7,739,000 (2014: £8,806,000). 

The majority of the group’s revenues are derived from large multinational organisations and are with established customers. Therefore 
the credit risk is considered to be small. We monitor customer D&B credit ratings and have had no material defaults in the past. None of 
our receivables are with customers where we have had any history of default.

An allowance has been made for estimated irrecoverable amounts from the sale of goods of £204,000 (2014: £330,000).  This 
allowance has been determined by reference to past default experience. The individually impaired receivables mainly relate to a number 
of independent customers. A portion of these receivables is expected to be recovered. 

The carrying values of trade and other receivables also represent their estimated fair values.    

Trade receivables and accrued income are primarily denominated in US dollars, as are trade payables (note 16). The natural hedge 
between these financial instruments limits the exposure of the group to movements in foreign exchange rates.  

Based on the balances held at 31 December 2015 a 1 cent movement in the US dollar to Sterling rate would impact the net value of 
these instruments by £53,000 (2014: £47,000) (before the mitigating impact of cash flow hedges).  

Liquidity risk 

Liquidity risk is the risk that the Group will not be able to meet its financial obligations as they fall due. The Group manages its funding to 
ensure, as far as possible, that it will always have sufficient liquidity to meet its liabilities when due, under both normal and stressed 
conditions, without incurring unacceptable losses or risking damage to the Group’s reputation. 

The Group uses weekly cash flow forecasts to monitor cash requirements and to optimise its borrowing position.  

Typically the Group ensures that it has sufficient borrowing facilities to meet foreseeable operational expenses. At the year end the group 
had available facilities of £41.1m (2014: £44.8m).

The group’s presentational currency is sterling. However, the majority of sales are denominated in US dollars.  Therefore, the group’s 
cash flows are affected by fluctuations in the rate of exchange between Sterling and the US dollar.  

This exposure is managed by a natural currency hedge because a significant portion of the group’s cost base is also denominated in US 
dollars.  In particular, the majority of the group’s raw materials are purchased in US dollars, and a significant portion of labour and 
overheads are also denominated in US dollars as three of the group’s principal subsidiaries are situated in North America.    

To a lesser extent, the group also generates sales in other currencies including Yen and Euros which are also partially hedged where 
possible by purchases of some raw materials in these currencies. 

Taking into account the extent of the natural hedge within the business model, management periodically use forward exchange 
contracts to mitigate the impact of the residual foreign currency exposure. As at 31 December 2015 and 31 December 2014 there were 
no contracts in place. 

(b) Fair value risk 

The group has operations in the UK, North America and Asia. Translation exposures that arise on converting the results of overseas 
subsidiaries are not hedged.  Net assets held in foreign currencies are hedged wherever practical by matching borrowings in the same 
currency.   

As a guide to the sensitivity of the group’s results to movements in foreign currency exchange rates, a one cent movement in the US 
dollar to Sterling rate would impact annual earnings by approximately £300,000 (2014: £200,000). 

2 - Interest rate risk 

The Board is aware of the risks associated with changes in interest rates and does not speculate on future changes in interest rates or 
currencies. Historically the Group has not undertaken any hedging activity in this area however the board keeps this under regular 
review. All foreign currency cash deposits are made at prevailing interest rates. The main element of interest rate risk concerns 
borrowings. 

The group’s bank borrowings consist of a series of variable and fixed rate term loans, a revolving credit facility and overdrafts. Bank 
loans are secured against the assets of the group.

2 - Interest rate risk (continued) 

The variable rate US dollar term loans, which had a principal outstanding at 31 December 2015 of £0.3m (2014: £1.3m), and bear 
interest of between 2.0% to 2.95% over LIBOR. These loans are repayable by monthly instalment with remaining terms of less than one 
year.  

The fixed rate US dollar term loans, which had a principal outstanding at 31 December 2015 of £2.1m (2014: £2.1m), and bear interest 
of 5% until 2017 and is variable thereafter. These loans are repayable by monthly instalment with remaining terms of up to 20 years.  

The US Dollar acquisition facility, which had a principal outstanding at 31 December 2015 of £8.1m (2014: £20.2 million), bears interest 
of between 2.5% to 2.95% over LIBOR. This loan is repayable by quarterly instalments with a remaining term of 2 years. 

The UK Pound revolving credit facility is a multi-currency facility of up to £30 million, committed until 2018.  It bears interest of between 
1.75% to 1.95% over LIBOR. The balance drawn at 31 December 2015 was £17.6m (2014: £12.3m). 

The group’s policy is to regularly review its exposure to interest rate risk, and in particular the mix between fixed and floating rate 
facilities.   The percentage of borrowings on fixed rate terms at 31 December 2015 was 8% (2014: 8%).  

Floating rate liabilities are primarily indexed to LIBOR. The group did not enter into any interest rate swap instruments during 2015.  This 
remains under regular review.  

As a guide to the sensitivity of the group’s results to movements in interest rates, a 50 basis point (0.5%) movement in interest rates 
would have impacted the 2015 annual interest charge by approximately £170,000 (2014: £170,000). 

The carrying value of loans approximates to their fair value based on the net present value of future cash flows. 

Capital risk management 

The group’s main objectives when managing capital are to safeguard the group’s ability to continue as a going concern in order to 
provide returns for shareholders and benefits for other stakeholders and to maintain an optimal capital structure to reduce the cost of 
capital. 

The group sets the amount of capital in proportion to risk.   The group manages the capital structure and makes adjustments to it in the 
light of changes in economic conditions and the characteristic of the underlying assets. The group monitors capital by reviewing net 
debt against shareholders’ funds.  The position of these indicators and the movement during the year is shown in the Five Year 
Financial Summary. 

The group defines total capital as equity in the consolidated balance sheet plus net debt or less net funds plus deferred consideration 
(note 16). Total capital at 31 December 2015 was £187,390,000 (2014: £173,039,000).  

Consistent with others in the industry, the group monitors capital on the basis of the gearing ratio. This ratio is calculated as net debt 
plus deferred consideration divided by total capital. At 31 December 2015 the gearing ratio was 22% (2014: 30%). 

All covenants in relation to the group’s borrowing facilities have been complied with during the year.

19 - Financial instruments (continued) 

Basis for determining fair value 

The following summarises the significant methods and assumptions used in estimating the fair values of financial instruments reflected 
in the table above. 

Secured loans 

As the loans are floating rate borrowings, amortised cost is deemed to reflect fair value excluding unamortised transaction fees. 

Trade and other receivables/payables 

As receivables/payables have a remaining life of less than one year, the notional amount is deemed to reflect the fair value. 

Financial Assets (Preference share receivables) 

As the preference shares receivables are floating rate receivables, amortised cost is deemed to reflect fair value.

21 - Share based payments 

The total amount charged to the income statement in 2015 in respect of share based payments was £2,001,000 (2014: £1,458,000). 
Included within the share based payments charge is a £1,186,000 (2014: £848,000) charge relating to the Company’s Long Term 
Incentive Plan. 

Share option scheme 

The IQE Plc Share Option Scheme was adopted on 26 May 2000 and amended by shareholders at the Annual General Meeting on 17 
May 2002.   Under the scheme, the Remuneration Committee can grant options over shares in the company to employees of the 
group.  

Options are granted with a contractual life of ten years and with a fixed exercise price equal to the market value of the shares under 
option at the date of grant or as otherwise disclosed in the remuneration report. Options become exercisable between one and four 
years from the date of grant subject to continued employment and the achievement of performance conditions, including growth in 
EBITDA and earnings per share against various targets. The group has no legal or constructive obligation to repurchase or settle the 
options in cash. 

Options are valued using the Black-Scholes option-pricing model and the total amount to be expensed is charged to income statement 
over the vesting period of the option. The principal assumptions used in the calculation of the fair value of share options are as follows: 

Principal assumptions

Weighted average share price at grant date

Weighted average exercise price

Weighted average vesting period (years)

Option life (years)

Weighted average expected life (years)

The expected volatility factor is based on historical share price volatility over the three years immediately preceding the grant of the 
option.  The expected life is the average expected period to exercise.  The risk free rate of return is the yield of zero-coupon UK 
government bonds of a term consistent with the assumed option life.  

Non-market performance conditions are incorporated into the calculation of fair value by estimating the proportion of share options that 
will vest and be exercised based on a combination of historical trends and future expected trading performance. These are reassessed 
at the end of each period for each tranche of unvested options.     

The fair value of options granted during the year ended 31 December 2015 was £33,000 (2014: £342,000).
