Synairgen is a respiratory drug discovery  
and development company with a focus on viral 
defence of the lungs. It is developing inhaled 
interferon beta (‘IFN-β’) in two programmes:
• To prevent asthma and COPD patients 

suffering severe exacerbations as a result  
of cold or flu infections

• To treat other patients who have been 

hospitalised with severe viral lung infections

Patents protecting the use of inhaled iFN-β to treat exacerbations 
of asthma and CoPD induced by rhinovirus (the common cold) 
have been granted in the USA, the EU and Japan.

in 2012 Synairgen announced positive data from its Phase ii 
proof of concept trial of inhaled iFN-β in asthma and is 
aiming to secure the right partnership arrangement to enable 
commencement of follow-on clinical trial activity during the 
2013-14 virus season.

Exacerbations (acute deteriorations of symptoms) represent the 
greatest unmet clinical need in asthma and CoPD. The common 
cold plays a major role in exacerbations, causing up to 80% of 
asthma exacerbations. For CoPD patients 50% of colds result 
in exacerbations. The annual direct healthcare cost of treating 
asthma and CoPD is very significant. in the USA it amounts 
to $54 billion1, of which $16 billion is for hospitalisations and 
Emergency Room visits.

Viruses are parasites which take over cells and use the cells’ 
‘machinery’ to replicate. The normal host cell response to viral 
infection is to trigger iFN-β production, which in turn orchestrates 
an anti-viral response (see page 10). Deficiencies in iFN-β 
production following infection explain why some patient groups 
(such as those with asthma and CoPD) are more susceptible to 
infection. many pathogenic respiratory viruses, such as  
influenza and SARS, can suppress iFN-β production, allowing 
infections to spread to the lungs and cause severe illness.

By delivering iFN-β to the lungs, Synairgen aims to overcome 
the iFN-β deficiency and restore/boost the lungs’ anti-viral 
defence mechanism.

I have suffered with asthma since I was 
10 years old. I lead a very normal life 
(swim 3 times a week and run regularly) 
until I get a cold. When I get a cold it 
goes straight to my chest and I get very 
wheezy and have to take my inhaler about 
20 times a day. I usually end up on oral 
steroids and/or antibiotics when I have a 
cold and have to have days off work. My 
colds seem to last a lot longer than any of 
my friends, and I often feel as though the 
entire winter is spent with a bad chest and 
not leading a normal life. Asthma is a 
chronic condition but it doesn’t affect my 
life until I get a cold.

Highlights for the year ended
31 December 2012

Operational highlights

● Positive data announced in April 2012 from the Phase II proof 

of concept trial of inhaled interferon beta (SNG001) being 
developed for the treatment or prevention of virus-induced 
asthma exacerbations, which showed:

● We are continuing to map out the different regulatory and 
clinical paths required to progress SNG001 to market in 
asthma and COPD. This is being progressed in parallel
with our business development discussions

●  British Thoracic Society Step 4/5 patients (estimated
to represent between 10% and 20% of adult asthma 
sufferers, who are the greatest healthcare burden)
suffer most due to cold viruses

●  Significant benefit across multiple endpoints in the

Step 4/5 population

●  Inhaled interferon beta is well tolerated

● The positive Phase II clinical trial data triggered comprehensive 
business development activity. Multiple parties are conducting 
detailed technical and commercial evaluations of SNG001. We 
aim to finalise arrangements with a primary partner to enable 
commencement of follow-on clinical trial activity during the 
2013 – 2014 virus season

● Biomarker analysis of Phase II study samples commenced

● We have commenced engagement with the US government 
to investigate the potential of SNG001 as a broad spectrum 
anti-viral treatment

● Expansion of patent portfolio, including grant of US patent

for compounds that induce interferon beta to treat or prevent 
rhinovirus (common cold)-induced exacerbations
in asthma or COPD

Financial highlights

● Balance sheet strengthened with fundraising of £2.5 million 

(gross) completed in July 2012

● Research and development expenditure for the year: 
£1.5 million (six months ended 31 December 2011:
£1.8 million)

● Post-tax loss for the year: £2.3 million (six months

ended 31 December 2011: £2.0 million)

● Cash at 31 December 2012: £3.1 million (31 December 2011: 

£3.4 million)

Chairman’s and 
Chief Executive Offi    cer’s Report

This has been a pivotal year for Synairgen, as its primary 
programme, SNG001 (inhaled interferon beta) to treat 
or prevent exacerbations of asthma and COPD, has 
produced positive Phase II clinical trial data. We also 
raised further funds to strengthen the balance sheet 
whilst we explore partnering opportunities.

Weeks of inhaled corticosteroid use (budesonide)

Synairgen’s inhaled SNG001 is being developed as a broad 
spectrum anti-viral therapy to be taken by asthmatic and 
COPD patients at the onset of cold (or infl uenza) symptoms. 
It is designed to treat and/or attenuate a deterioration 
of asthma or COPD symptoms and prevent severe 
exacerbations that require intensive treatment with oral 
therapies such as steroids or antibiotics. It has long been 
established that common viruses are a major cause

of exacerbations and hospitalisations in these diseases.
The rationale for developing inhaled SNG001 came from 
the observation that cells from asthmatic patients and 
COPD patients’ lungs respond poorly to viruses, and do not 
produce enough of the key anti-viral protein interferon beta. 
Adding interferon beta to the cells restores and boosts the 
anti-viral defences.

When I get a cold it lasts a couple of days 
and then goes, then a few days later it 
hits me again and that’s when my chest is 
really bad. I cough a lot more than usual 
and have a lot of mucus. It is much worse  
when I get up. I can't do a great deal, 
especially in the morning, and then it 
gets better as the day goes on. I have to 
take my inhalers more regularly.  I don't 
like going to the doctors and it takes me a 
long time to get an appointment. They often 
give me steroids and antibiotics. I just feel 
drained and it takes me a long time to get 
back to normal again. I haven't really been 
back to normal since Christmas. It wears 
me down and drains my energy.

Results of Phase II trial
In April we announced preliminary results from the trial. Since then 
we have continued to review the mass of data generated by this 
study alongside key opinion leaders in the fi eld. The results were 
presented by Prof. Ratko Djukanovic at the European Respiratory 
Society in September 2012 and were well received. The results 
have also recently been submitted for publication. 

In the trial, 147 patients with a wide range of asthma severity were 
treated with either SNG001 or placebo at the early signs of a cold 
infection. Of the 147, 134 went on to develop a full cold (the other 
13 patients either did not provide data to be able to confi rm a cold, 
or the cold symptoms did not materialise).

Various endpoints were assessed to establish whether SNG001 
was providing benefi t to these asthmatic patients during 
respiratory virus infections. The primary endpoint was a measure 
of change in asthma symptoms during the fi rst week of treatment 
using the shortened Asthma Control Questionnaire (sACQ).
In the treated population who got colds, there appeared to be 
minimal benefi t. Essentially the cold infection was not impacting 
on patients’ asthma as seriously as expected, thus there was little 
opportunity for an intervention to demonstrate effi cacy and there 
was no statistically signifi cant difference. However for lung function 
(morning peak expiratory fl ow, a secondary/exploratory endpoint) 
there was a statistically signifi cant benefi t for patients receiving 
SNG001. This in itself is very encouraging.  

A review of patients whose asthma deteriorated to the point where 
they were prescribed oral steroids (or antibiotics) to treat their 
exacerbation showed that fi ve patients receiving placebo and 
one patient receiving SNG001 required this more serious level of 
intervention to treat their asthma exacerbation. One of the patients 
on placebo was hospitalised for fi ve days for their asthma.  

Of particular interest to us was that all fi ve of the placebo patients 
who received oral corticosteroids or antibiotics to treat their 
exacerbation were in the British Thoracic Society (BTS) Step 4 
classifi cation. The BTS Step classifi cation system ranges from 1 
to 5, with Step 1 patients being least intensively treated to Step 5 
being the most intensively treated. BTS Step 4 patients, who are 
recognised as ‘diffi cult to treat’, receive close to maximal routine 
inhaled therapies (i.e. higher doses of inhaled corticosteroids - an 
anti-infl ammatory - and a long acting beta agonist (bronchodilator) 
as a minimum). None of the Step 4 or Step 5 SNG001-treated 
patients required this higher level of intervention (i.e. oral steroids 
or antibiotics). This led us to investigate the possibility that this 
population may be the patient group who not only suffer most 
during respiratory virus infections, but also respond best to 
SNG001 treatment.

Analysis of sub populations according to BTS Step group
The first observation was that there were disproportionately 
more (approaching half) Step 4 and Step 5 patients in the trial 
than one would find in the general asthma population, where 
10% to 20% would be expected. We believe the trial radio advert 
recruitment wording, “Does your asthma get worse when you 
get a cold?”, created a positive bias that resulted in the selection 
of patients whose asthma deteriorates most when they get a 
cold.  

An assessment of asthma control using the sACQ (as used for 
the primary endpoint) showed that in the first week of the cold 
there was a marked worsening in patients on placebo, whereas 
patients on SNG001 showed a movement returning towards 
their screening (uninfected) level of control. The difference on 
the sACQ scale of 0.63 in favour of SNG001 exceeded the 
threshold considered to be clinically relevant (> 0.5) and was 
statistically significant (p=0.004).  

A similar subgroup analysis of the lung function (morning peak 
expiratory flow) changes, which were significantly better for the 
overall population in the trial (as referred to above), showed that 
the positive effects of SNG001 were minimal for the ‘milder’ 
Step 2 patients (difference of 6 litres/min), approaching clinical 
relevance (17 litres/min) for the Step 3 patients, and exceeding 
the clinically relevant difference of 20 litres/min in the Step 4 
patients (31 litres/min).  

This trial has been successful on three counts: 

•  Firstly, we have identified the patient group which appears to 
suffer most due to cold viruses; this is the Step 4 and Step 
5 patients. Patients at lower Steps have other therapeutic 
options: they have greater scope to increase the doses of their 
existing routine daily medication, and it is also quite possible 
that compliance to medication may increase at times of 
infection. 
It appears that Step 4 patients are more likely to use more 
potent drugs, such as oral corticosteroids.  

•  Secondly, in these Step 4/5 patients, treatment with SNG001 
was beneficial in terms of the number of patients requiring oral 
therapies, improvement in asthma control, and accelerating the 
recovery in lung function.  

•  Thirdly, SNG001 appears to be well tolerated, and there was 

no evidence of systemic absorption.

Chairman’s and  
Chief Executive Officer’s Report (continued)

Business Development
The positive data from the Phase II clinical trial has triggered 
comprehensive business development activity. This process has 
identified multiple parties with established commercial respiratory 
franchises who are interested in this therapeutic area. During the 
period, we have devoted significant time and resource to enable 
potential partners to conduct technical and commercial evaluations 
of SNG001. Given the novelty of this potential treatment we have 
worked up a number of options regarding clinical and regulatory 
development pathways for SNG001. We aim to secure the right 
partnership arrangement to enable commencement of follow-on 
clinical trial activity during the 2013 – 2014 virus season and we are 
confident that this process can achieve that goal. 

Biomarker analysis of Phase II samples
We are also progressing well with the analysis of samples from 
our Phase II study in asthma. A panel of possible gene and protein 
biomarkers have been identified and are the subject of further 
investigations. We shall provide updates on this activity which is 
designed to underpin the clinical observations, and also identify 
potential prognostic biomarkers.

Intellectual property
During the year, a US patent was granted for compounds that 
induce interferon beta to treat or prevent rhinovirus (common 
cold)-induced exacerbations in asthma or COPD. This is important 
intellectual property for the Company, as it prevents inducers of 
interferon beta, such as toll-like receptor agonists, being developed 
to do the same role as SNG001.

Severe viral lung infections
We submitted an application to the US National Institutes of Health 
to support activity that will progress inhaled SNG001 towards 
the non-asthma, non-COPD market, which is to treat patients 
hospitalised with severe viral lung infections. We expect to hear 
whether we have been successful during this summer.

In summary 
In 2012 our interferon beta programme achieved a significant 
milestone, generating persuasive efficacy data within the group of 
asthma patients that we are seeking to treat. We are now planning 
the further development of this exciting therapy and are focussed on 
securing the right partnership to help us deliver it.

Clinical development plan
We are making very good progress with regard to preparation 
of materials (e.g. protocols) for follow-on studies in asthma and 
COPD. These are being progressed in parallel with our business 
development discussions. Each potential partner has a slightly 
different view on how this should be progressed, but all are still valid 
approaches for this innovative programme.

Financial Review

The Financial Review should be read in conjunction with the 
consolidated financial statements of the Company and Synairgen 
Research Limited (together the ‘Group’) and the notes thereto 
on pages 25 to 38. The consolidated financial statements are 
presented under International Financial Reporting Standards 
as adopted by the European Union. The financial statements 
of the Company continue to be prepared in accordance with 
UK Generally Accepted Accounting Practice and are set out 
on pages 39 to 42. During the previous accounting period, the 
Group brought forward its financial year-end from 30 June to 31 
December and as a result comparative financial information in this 
annual report is for the six months ended 31 December 2011.

Statement of Comprehensive Income
The loss from operations for the year ended 31 December 2012 
was £2.49 million (six months ended 31 December 2011: £2.24 
million). Research and development expenditure for the year 
amounted to £1.51 million (six months ended 31 December 
2011: £1.82 million). The proportionate reduction in research 
and development expenditure was due to the completion early 
in the year of both the asthma Phase II study (SG005) and the 
pre-clinical study in viral pneumonia. The most significant item of 
continuing research and development during the year has been 
the analysis of data and samples collected from SG005. 

Other administrative costs for the year amounted to £0.98 million 
(six months ended 31 December 2011: £0.42 million). The research 
and development tax credit for the year, in line with the reduction 
in expenditure, was £0.21 million (six months ended 31 December 
2011: £0.25 million). The loss after tax for the year was £2.25 
million (six months ended 31 December 2011: £1.97 million) and 
the loss per share was 3.12p (six months ended 31 December 
2011: loss of 2.83p).

Treasury policy and financial risk management

Credit risk
The Group follows a risk-averse policy of treasury management. 
Sterling deposits are held with one or more approved UK-based 
financial institutions. The Group’s primary treasury objective is to 
minimise exposure to potential capital losses whilst at the same 
time securing prevailing market rates.

Interest rate risk
The Group’s cash held in current bank accounts is subject to the 
risk of fluctuating base rates. A substantial element of the Group’s 
financial assets is placed on fixed-term interest deposits. The interest 
rate profile of financial assets is illustrated in note 16 to the financial 
statements.

Currency risk
During the year under review, the Group was exposed to Euro 
and Australian dollar exposure as a small element of its research 
and development expenditure is denominated in these currencies. 
The Group does not routinely hedge against this exposure.

Capital structure and funding
The Group is funded by equity capital, reflecting the early stage 
nature of its discovery and development programmes.

The Group considers its capital to be its total equity, which at 31 
December 2012 amounted to £3.42 million (31 December 2011: 
£3.12 million). The Group’s objectives when managing capital are 
to safeguard the Group’s ability to continue as a going concern 
in order to provide returns to equity holders of the Company and 
benefits to other stakeholders and to maintain an optimal capital 
structure to reduce the cost of capital. The Group manages this 
objective through tight control of its cash resources and, upon 
reaching significant drug development programme milestones 
(to decrease investment risk), by raising additional equity from 
shareholders to meet its forecast future cash requirements.

Fundraising
In July 2012, the Company raised £2.50 million (gross) through the 
issue of 5.56 million shares at a price of 45p per share. Costs of 
the issue amounted to £0.15 million (6.0%).

Net funds held by the Group at 31 December 2012 amounted to 
£3.09 million and comprised cash and cash equivalents, short-term 
deposits (with original maturities of greater than three months and 
less than one year) as shown below:

Statement of Financial Position and cash flows
At 31 December 2012, net assets amounted to £3.42 million 
(31 December 2011: £3.12 million), including net funds, as detailed 
below in Capital structure and funding, of £3.09 million 
(31 December 2011: £3.35 million).

The principal elements of the £0.26 million decrease over the year 
ended 31 December 2012 (six months ended 31 December 2011: 
£1.54 million decrease) in net funds were:

•	 Cash used in operations of £2.75 million (six months ended 

31 December 2011: £1.93 million outflow);

•	 Research and development tax credits received of £0.25 million 

(six months ended 31 December 2011: £0.40 million);

•	 Investment into intangible assets (patents and licences) £0.14 

million (six months ended 31 December 2011: £0.02 million); and

•	 Share issue proceeds (net of costs) £2.35 million (six months 

ended 31 December 2011: £nil).

The Group did not have any bank borrowings as at 31 December 
2012 (31 December 2011: £nil).

There have been five significant issues of shares with the following 
amounts (net of costs) raised: £0.62 million (August 2003); £8.98 
million (from IPO on AIM in October 2004); £6.20 million (June 
2009); £2.50 million (June 2011); and £2.35 million (July 2012). 
The other major sources of funding received by the Group from 
the formation of the business until 31 December 2012 have been: 
research and development tax credits of £2.22 million, bank 
interest of £1.60 million, and revenues from collaborative work 
of £0.60 million.

Scientific Review – The key role of interferons  
in defending the body against infection

Interferons (‘IFNs’) are proteins made and released by cells as 
part of the body’s immune response to infection and cancer. 
Historically IFNs were named because of their ability to ‘interfere’ 
with viral replication within cells1.

There are three types of IFN, each type activates different 
receptors on the surface of cells resulting in different biological 
responses. Type I IFNs (IFN-α and IFN-β) are essential for 
immunity against most viruses. The more recently identified Type 
III IFNs (IFN-λ 1, IFN-λ2 and IFN-λ3) also play a role in anti-viral 
defence, although their relative importance to Type I IFNs is still to 
be fully understood. IFN-γ is the only Type II IFN and it is important 
for immunity against bacteria, fungi, and parasites.

Defects in the production of, or response to, IFNs are associated 
with an increased susceptibility to infection. For example, mice 
lacking the Type I IFN are highly susceptible to infection with a 
range of viruses despite an otherwise intact immune system2. 
Similarly, people with genetic defects in IFN pathways are prone  
to serious life-threatening infections3.

Anti-viral activities of Type I IFNs 
Viruses are microscopic organisms consisting of genetic 
material (RNA or DNA) surrounded by a protein coat. They are 
not capable of replicating on their own (unlike bacteria) and so 
have to invade cells and ‘hijack’ their replication machinery. 
After latching onto a cell, a virus will insert its genetic material 
into the cell and direct it to make copies of the viral genetic 
material, structural components and the enzymes needed 
to produce and assemble new virus particles (virions). 
Having made many thousands of new virions, the cell finally 
dies, releasing the new viral particles, which can then infect 
surrounding cells.
Synairgen is developing an inhaled form of IFN-β. IFN-β 
plays an indispensable role in limiting viral infection within 
the body. Production and release of IFN-β is triggered when 
viral genetic material is detected by receptors inside cells. 
IFN-β can then bind to and activate Type I IFN receptors on 
the surface of nearby cells, resulting in the ‘switching on’ of 
hundreds of Interferon Stimulated Genes (‘ISG’), including 
Type I IFN genes, which orchestrate the anti-viral response 
within cells and the wider immune response to infection 
(Figure 1).

➊  In cells which cannot limit viral replication IFN-β causes 
controlled cell death or ‘cell suicide’ in a process known 
as apoptosis. By dying, the cell can no longer support viral 
replication, thus limiting the spread of the infection. Cells 
which die by apoptosis can be cleared by immune cells 
(macrophages) without causing further infl ammation. 

➋  In uninfected cells and infected cells in which the infection 
has not yet taken hold, IFN-β switches the cell into an 
‘Anti-viral State’ by driving the expression of numerous 
Interferon Stimulated Genes (ISG) products that act together 
to limit replication of many different virus types. By switching 
on anti-viral defences in surrounding uninfected cells IFN-β 
prevents the spread of the infection.

➌  IFN-β and ISG products also have additional benefi cial 

effects on the wider immune response including promoting 
the recruitment of immune cells (NK cells and CD8+ T-cells) 
to the site of infection to eliminate virus infected cells and 
mechanisms leading to the production of antibodies against 
virus (by B-cells) which prevent the virus binding to and 
infecting cells. Antibodies not only limit the ongoing infection 
but can also provide long lasting immunity against the virus.

Scientific Review – The key role of 
interferons in defending the body 
against infection (continued)

Type I IFNs as anti-viral treatments
Recognising the potential of Type I IFNs to modify the body’s 
immune response, a number of man-made mimics have been 
successfully developed as drugs. These include a number of 
injectable IFN-α related products (such as Intron-A®, Roferon®, 
Infergen®, Pegasys® and Pegintron®) that have been developed 
as anti-virals for the treatment of hepatitis and/or treatments for 
cancers. Injectable IFN-β related products have been developed 
as treatments for the nervous system disease multiple sclerosis 
(‘MS’), these include Rebif®, Avonex®, Betaferon®/Betaseron® and 
Extavia®. MS is a disease in which the nerves of the brain and 
spinal cord are mistakenly targeted by the immune system. The 
way IFN-β works in MS in not fully understood but it is believed to 
involve modulation of the immune response resulting in reduced 
inflammation and damage4.

Inhaled IFN-β as a treatment for virus induced 
exacerbations of respiratory disease
Respiratory virus infections such as the common cold and 
influenza are strongly associated with exacerbations of respiratory 
diseases such as asthma, chronic obstructive pulmonary disease 
(COPD) and cystic fibrosis. There is growing evidence that this 
association can be explained by a local increase in susceptibility to 
viral infection in the lungs of these patients, caused by a deficiency 
to produce IFN-β in response to a viral infection5-10.  

In the laboratory it has been observed that the addition of small 
amounts of human IFN-β to lung cell cultures from patients with 
chronic respiratory disease can restore their anti-viral responses 
and protect cells from respiratory viruses associated with asthma 
exacerbations (especially rhinoviruses but also others such as 
respiratory syncytial virus and influenza). These findings have been 
translated to clinical application by Synairgen to see if IFN-β can 
be used as a potential treatment for virus-induced exacerbations 
of chronic lung disease. In our recent clinical trial we found that 
when compared to placebo, the administration of inhaled IFN-β 
could prevent worsening asthma symptoms and exacerbations, 
and improve lung function in “more difficult to treat” asthmatics 
suffering from an upper respiratory tract infection (such as the 
common cold). Thus, by administering IFN-β directly to the  
lungs of asthmatics we could correct the deficiency and restore 
anti-viral defences thus preventing the spread of the infection and 
worsening lung inflammation. Further clinical studies are planned 
to confirm the result of this study in asthma and explore the 
potential of adopting a similar approach in COPD.

Directors’ Report

The Directors present their report and the audited fi  nancial 
statements for Synairgen plc (the ‘Company’) and its subsidiary 
(together the ‘Group’) for the year ended 31 December 2012.   

Principal activities
Synairgen plc is the holding company for Synairgen Research Limited, 
a respiratory drug discovery and development company with a 
particular focus on viral defence.

Review of the business and future developments
A review of the business and anticipated future developments is 
included in the Chairman’s and Chief Executive Offi    cer’s Report and 
the Financial Review set out on pages 3 to 8.

Research and development
During the year ended 31 December 2012, the Group has invested 
£1,508,000 (six months ended 31 December 2011: £1,815,000) in 
research and development activities and a review of this expenditure 
is included in the Financial Review.

Principal risks and uncertainties
The Board considers that the principal risks and uncertainties facing 
the Group may be summarised as follows:

•	 Reliance on the interferon beta programmes
All of the Group’s resources are focused on the three interferon beta 
programmes. Whilst these are three separate indications (asthma, 
COPD and severe viral lung infections), there is a risk that failure in 
one indication may have a negative impact upon the others.   
•	 Failure to generate innovative discoveries
There can be no guarantee that the Group will successfully develop 
new pharmaceutical products.
•	 Clinical development and regulatory risk
The development of pharmaceutical drugs requires the necessary 
safety and effi    cacy to be demonstrated in clinical programmes in 
order to meet the requirements of the appropriate regulatory bodies. 
There can be no guarantee that the necessary safety or effi    cacy will be 
demonstrated or that the clinical trials will not be delayed or extended. 
There can be no guarantee that any of the Group’s therapies will be 
able to obtain or maintain the necessary regulatory approvals. The 
Group seeks to reduce this risk by closely monitoring the progress 
of recruitment on its clinical trials, drawing on the experience of 
its Founders, seeking advice from regulatory advisers, and holding 
consultations with the appropriate regulatory bodies.
•	 Intellectual property risk
The commercial success of the Group depends on its ability to obtain 
patent protection for its pharmaceutical discoveries in the US, Europe 
and other countries and to preserve the confi dentiality of its know-
how. There is no guarantee that patent applications will succeed or 
be broad enough to provide protection for the Group’s intellectual 
property rights and exclude competitors with similar pharmaceutical 
products. The success of the Group is also dependent on non-
infringement of patents, or other intellectual property rights, held 
by third parties. Competitors and third parties may hold intellectual 
property rights which the Group may not be able to license upon 
favourable terms, potentially inhibiting the Group’s ability to develop 
and exploit its own business. Litigation may be necessary to protect 
the Group’s intellectual property which may result in substantial costs.

The Group seeks to reduce this risk by seeking patent attorney advice 
that patent protection will be available prior to investing in a project, 
by seeking patent protection where appropriate and by minimising 
disclosure to third parties.
•	 Commercial risk
There can be no guarantee that the Group will succeed in securing 
and maintaining the necessary contractual relationships with 
licensing partners for its programmes under development. Even if 
the programmes are successfully out-licensed and pharmaceutical 
products are brought to market by a partner, there is no guarantee that 
such products will succeed in the marketplace.
The Group seeks to reduce this risk by structuring its development 
programmes to meet the needs and requirements of its potential 
partners and by engaging with partners who have the appropriate 
experience, resource and interest to bring such pharmaceutical 
products to the global marketplace.
•	 Competition risk
The Group’s current and potential competitors include pharmaceutical 
and biotechnology companies and academic institutions, many of 
whom have signifi cantly greater fi  nancial resources than the Group. 
There can be no assurance that competitors will not succeed in 
developing products that are more eff  ective or economic than any 
developed by the Group, or which would render the Group’s products 
non-competitive or obsolete. 
•	 Funding risk
The Group continues to consume cash resources. Until the Group 
generates positive net cash infl  ows from successful out-licensing 
transactions and commercialisation of its products, it remains 
dependent upon securing additional funding through the injection 
of capital from share issues. The Group may not be able to generate 
positive net cash fl ows in the future or attract such additional funding 
required at all, or on suitable terms. In such circumstances, the 
Group’s discovery and development programmes may be delayed or 
cancelled and the business operations curtailed.
The Group seeks to reduce this risk through tight fi  nancial control, 
prioritising programmes which will generate the best returns and 
keeping shareholders informed on progress.
•	 Dependence on Founders, senior management and key staff
The Founders and certain members of staff   are highly skilled 
scientists and clinicians. The Group has deliberately pursued a 
lean headcount policy to conserve fi  nancial resources. Failure to 
continue to attract and retain such individuals could adversely aff  ect 
operational results.  
The Group seeks to reduce this risk by appropriate incentivisation of 
staff   through participation in long term equity incentive schemes.
Key performance indicators (‘KPIs’)
The Board considers that the most important KPIs are non-fi  nancial 
and relate to the progress of the scientifi c programmes which are 
discussed in the Chairman’s and Chief Executive Offi    cer’s Report. 
The most important fi  nancial KPIs are the cash position and the 
operating loss of the Group. At 31 December 2012 cash and deposit 
balances amounted to £3.09 million and were above budgeted 
levels. The operating loss of £2.49 million was also favourable to 
the budgeted loss for the year.

Corporate Governance

The Board is accountable to the Company’s shareholders for good 
corporate governance and it is the objective of the Board to attain a high 
standard of corporate governance. As an AIM-quoted company, full 
compliance with The UK Corporate Governance Code (the ‘Code’) is not 
a formal obligation. The Company has not sought to comply with the full 
provisions of the Code, however it has sought to adopt the provisions that 
are appropriate to its size and organisation and establish frameworks for 
the achievement of this objective. This statement sets out the corporate 
governance procedures that are in place.

Board of Directors
On 31 December 2012 the Board of Directors (the ‘Board’) consisted 
of a non-executive Chairman (Simon Shaw), three executive 
Directors (Richard Marsden, Dr Phillip Monk and John Ward), and 
four non-executive Directors (Iain Buchanan, Dr Bruce Campbell, 
Paul Clegg and Prof. Stephen Holgate). Brief details about the 
Directors are given on pages 13 and 14. The responsibilities of the 
non-executive Chairman and the Chief Executive Officer are clearly 
divided. The non-executive Directors bring relevant experience 
from different backgrounds and receive a fixed fee for their services 
and reimbursement of reasonable expenses incurred in attending 
meetings.  
The Board retains full and effective control of the Group. This includes 
responsibility for determining the Group’s strategy and for approving 
budgets and business plans to fulfil this strategy. The full Board 
ordinarily meets bi-monthly. It also meets on any other occasions it 
considers necessary. During the year ended 31 December 2012, the 
Board met ten times, with each member attending as follows: 

Director

Simon Shaw
Richard Marsden
Dr Phillip Monk
John Ward

It is the duty of the Chairman to ensure that all Directors are properly 
briefed on issues arising at Board meetings. Prior to each Board 
meeting, Directors are sent an agenda and Board papers for each 
agenda item to be discussed. Additional information is provided 
when requested by the Board or individual Directors.
The Company Secretary is responsible to the Board for ensuring 
that Board procedures are followed and that the applicable rules and 
regulations are complied with. All Directors have access to the advice 
and services of the Company Secretary, and independent professional 
advice, if required, at the Company’s expense. Removal of the 
Company Secretary would be a matter for the Board.
As appropriate, the Board has delegated certain responsibilities to 
Board committees.

Audit Committee
The Audit Committee currently comprises Simon Shaw (Chairman) 
and Dr Bruce Campbell. Whilst it is not normal in larger companies 
for the chairman of the Company to chair the Audit Committee, the 
Company considers it appropriate for Simon Shaw to be Chairman as 
he is considered to have the most significant, recent and relevant 
financial experience of the non-executive Directors. 
The committee has primary responsibility for ensuring that the 
financial performance of the Group is properly measured and 
reported on and it reviews the interim financial information and 
annual financial statements before they are submitted to the Board. 
The committee reviews accounting policies and material accounting 
judgements. The committee also reviews, and reports on, reports 
from the Group’s auditors relating to the Group’s accounting controls. 
It makes recommendations to the Board on the appointment of 
auditors and the audit fee. The committee monitors the scope, results 
and cost-effectiveness of the audit. It has unrestricted access to the 
Group’s auditors. In certain circumstances it is permitted by the 
Board for the auditors to supply non-audit services (in the provision 
of tax advice, or on specific projects where they can add value). 
The committee has approved and monitored the application of this 
policy in order to safeguard auditor objectivity and independence. 
The overall fees paid to the auditors are not deemed to be of such 
significance to them as to impair their independence. The Group does 
not have an internal audit function, but the Board considers that this 
is appropriate, given the size of the Group. The committee keeps this 
matter under review annually. During the year ended 31 December 
2012, the committee met four times and all meetings were attended 
by Simon Shaw and Dr Bruce Campbell.

Remuneration and Nomination Committee
The Remuneration and Nomination Committee currently comprises 
Paul Clegg (Chairman), Dr Bruce Campbell and Simon Shaw. The 
committee is responsible for making recommendations to the Board 
on remuneration policy for executive Directors and the terms of their 
service contracts, with the aim of ensuring that their remuneration, 
including any share options and other awards, is based on their 
own performance and that of the Group generally. The committee 
administers the Long-Term Incentive Plan, the staff share option 
scheme and the Qualifying Non-Employee Option Scheme and 
approves grants under all three schemes. It also advises on the 
remuneration policy for the Group’s employees. The committee is 
responsible for all senior appointments that are made within the 
Group. During the year ended 31 December 2012, the committee 
met four times, with each member attending as follows:

Corporate Governance (continued)

Investor relations
The Directors seek to build a mutual understanding of objectives 
between the Company and its shareholders by meetings with major 
institutional investors and analysts after the Company’s preliminary 
announcement of its year-end results and its interim results. The 
Company also maintains investor relations pages on its website (www.
synairgen.com) to increase the amount of information available to 
investors. During the year, with the assistance of its retained financial 
public relations adviser (Newgate Threadneedle), the Directors have 
also had meetings with a number of private client stockbrokers around 
the UK to raise awareness of the Company.
There is an opportunity at the Annual General Meeting for individual 
shareholders to question the Chairman, the Chairmen of the Audit 
and Remuneration and Nomination committees, and the executive 
Directors. Notice of the meeting is sent to shareholders at least 21 clear 
days before the meeting. Shareholders are given the opportunity to 
vote on each separate issue. The Company counts all proxy votes and 
will indicate the level of proxies lodged on each resolution, after it 
has been dealt with by a show of hands. Details of the resolutions and 
explanations thereto are included with the notice. 

Internal control
The Directors are responsible for establishing and maintaining the 
Group’s system of internal control and reviewing its effectiveness. The 
system of internal control is designed to manage, rather than eliminate, 
the risk of failure to achieve business objectives and can only provide 
reasonable but not absolute assurance against material misstatement 
or loss.
The main features of the internal control system are as follows:

•	 a control environment exists through the close management of 

the business by the executive Directors. The Group has a defined 
organisational structure with delineated approval limits. 
Controls are implemented and monitored by personnel with the 
necessary qualifications and experience;

•	 a list of matters reserved for Board approval;

•	 monthly management reporting and analysis of variances;

•	 financial risks for each major transaction are identified and 

evaluated by the Board; and

•	 standard financial controls operate to ensure that the assets of 
the Group are safeguarded and that proper accounting records 
are maintained.

Directors’ Remuneration Report

This report is non-mandatory for AIM-quoted companies and has 
been produced on a voluntary basis. It includes and complies with the 
disclosure obligations of the AIM Rules and with the principal disclosure 
requirements of Schedule 5 of the Large and Medium-sized Companies 
and Groups (Accounts and Reports) Regulations 2008.

Remuneration Committee
The Company’s remuneration policy is the responsibility of the 
Remuneration and Nomination Committee (the ‘Committee’), which was 
established in October 2004. The terms of reference of the Committee 
are outlined in the Corporate Governance Statement on page 18. The 
members of the Committee are Paul Clegg (Chairman), Simon Shaw 
and Dr Bruce Campbell.
The Committee, which is required to meet at least twice a year, met four 
times during the year ended 31 December 2012. The Chief Executive 
Officer and certain executives may be invited to attend meetings of the 
Committee to assist it with its deliberations, but no executive is present 
when his or her own remuneration is discussed.
During the year, the Committee has been advised on Director 
remuneration by its retained independent remuneration adviser, 
FIT Remuneration Consultants LLP. No other advice has been 
provided to the Group by this firm during the year.  

Remuneration policy
(i) Executive remuneration
The Committee has a duty to establish a remuneration policy which will 
enable it to attract and retain individuals of the highest calibre to run the 
Group. Its policy is to ensure that the executive remuneration packages 
of Executive Directors and the fee of the Chairman are appropriate given 
performance, scale of responsibility, experience, and consideration of 
the remuneration packages for similar executive positions in companies 
it considers are comparable. Packages are structured to motivate 
executives to achieve the highest level of performance in line with 
the best interests of shareholders. A significant element of the total 
remuneration package, in the form of bonus and LTIP awards, 
is performance driven.  
Executive remuneration currently comprises a base salary, an annual 
performance-related bonus, a pension contribution to the executive 
Director’s individual money purchase scheme (at 9% of base salary), 
family private health cover, permanent health and life assurance. 
Salaries and benefits are reviewed annually in July, taking into account 
Group and individual performance, external benchmark information 
and internal relativities, but it is the intention of the Company to align 
this with the financial year-end of the Company with effect from 
1 January 2014. The Company operates a discretionary bonus scheme 
for executive Directors for delivery of exceptional performance against 
personal and corporate objectives, with the maximum bonus payable 
remaining at 200% of base salary. Bonuses payable to executive 
Directors in respect of the year ended 31 December 2012 were 34% of 
base salary, amounting to £44,000 for Richard Marsden, £33,000 for Dr 
Phillip Monk and £40,000 for John Ward. Pay rises awarded to executive 
Directors with effect from 1 July 2012 amounted to 3%, which was 
broadly consistent with the increase awarded to staff generally. 

Executive Directors are also rewarded for improvements in the 
performance of the Group sustained over a period of years in the form of 
Long-Term Incentive Plan share awards granted on a discretionary basis 
by the Committee.
Directors’ remuneration for the year ended 31 December 2012 is set out 
on page 22 of this document.

(ii) Chairman and non-executive Director remuneration
The Chairman, Mr Buchanan and Mr Clegg receive a fixed fee of £25,000 
per annum. Dr Campbell and Professor Holgate receive a fixed fee of 
£15,000 per annum. The fixed fee covers preparation for and attendance 
at meetings of the full Board and committees thereof. A fee of £5,000 
per annum is also paid for chairing each of the audit and remuneration 
committees. The Chairman and the executive Directors are responsible 
for setting the level of non-executive remuneration. These fees remain 
unchanged from 1 September 2009. The non-executive Directors are 
also reimbursed for all reasonable expenses incurred in attending 
meetings.   

(iii) Equity-based incentive schemes
The Committee strongly believes that equity-based incentive schemes 
increase the focus of employees in improving Group performance, 
whilst at the same time providing a strong incentive for retaining and 
attracting individuals of a high calibre. 

Long-Term Incentive Plan (‘LTIP’)
The Synairgen Long-Term Incentive Plan, comprising conditional 
(performance-related) share awards (technically structured as nominal 
cost options pursuant to which participants must pay 1p per share on 
the exercise of their awards), was introduced in 2005 as the primary 
long-term incentive vehicle for executive Directors. Senior executives 
and other employees may be granted an award which will normally vest 
if demanding performance conditions are achieved over a three-year 
period and if the grantee remains an employee of the Group.  
Grants under the LTIP in any financial year are capped at a maximum of 
100% of base salary. Historically, grants have been made in September 
following the publication of the final results for the year to June. The last 
grants were made in September 2011. Following, the change in year-end 
to 31 December, it was not considered appropriate to accelerate the date 
of grants so no grants were made during 2012. Instead, it is anticipated 
that grants will continue to be made following the publication of the 
final results in or around February each year with the next such grant 
following the results in February 2013. Executive Directors are expected 
to retain no fewer than 50% of shares acquired upon vesting of awards 
under the LTIP, net of taxes, until such time as, in combination with any 
other shares the executives may have acquired, they hold shares with a 
value equivalent to 100% of base salary.  
All awards will lapse at the end of the applicable performance period to 
the extent that the applicable performance criteria conditions have not 
been satisfied with no opportunity for retesting. In the event of a good 
leaver event or a change of control of the Company, the LTIP awards may 
vest early, but only to the extent that, in the opinion of the Committee, 
the performance conditions have been satisfied at that time. The awards 
will generally also be subject to a time pro-rated reduction to reflect the 
reduced period of time between the grant of the awards and the time of 
vesting although this reduction may not be applied in certain cases.

Directors’ Remuneration Report (continued)

Performance conditions for the 2009, 2010 and 2011 LTIP awards
The performance conditions for all three awards were the same. The 
awards are subject to two conditions. Firstly, awards will only vest to 
the extent that the percentage increase in the total shareholder return 
(‘TSR’, being the return earned by a shareholder over the performance 
period in terms of change in the share price and assuming re-
investment of any dividends in more shares at the prevailing price 
on the relevant ex-dividend date) of the Company over the three year 
performance period is equal or greater than the percentage increase in 
the techMARK mediscience™ index over the same period as follows: 

TSR growth over the performance period 
less percentage increase in the techMARK 
mediscience™ index over the same period

Vesting percentage  
of total number of shares  
subject to award

Less than 0%
0%
10% 
20% 
Performance between the steps

0%
25%
50%
100%
Pro-rata on a straight-line basis

Secondly, no award will vest unless the average annual growth in the 
TSR of the Company over the performance period is equal to or greater 
than RPI plus 2% or, for more than 75% of an award to vest, annual 
average TSR must exceed RPI by at least 5% rather than 2%.
Vesting of 2009 LTIP awards
In September 2012, the awards granted in 2009 vested in full. The TSR 
growth over the three year performance period amounted to 110% and 
the percentage increase in the techMARK mediscience™ index over 
the same period was 34%, resulting in an outperformance by 76%, 
thus meeting in full the first performance condition. Similarly, this 
significantly exceeded the RPI underpin.
Qualifying Non-Employee Option Scheme (‘QNEOS’)
On 12 June 2009 shareholders in General Meeting approved the 
adoption of the QNEOS. This plan is a discretionary share scheme 
which enables the Committee to grant market value share options to 
consultants and non-executive Directors who, in the opinion of the 
Committee, make, or, in the case of new appointments, will make, 
a significant contribution to the Group and where the Committee 
considers it to be in the interests of shareholders to make such grants.
During the year under review no options were granted under the 
QNEOS.
Vesting of 2009 QNEOS awards
In September and October 2012 the awards made in September and 
October 2009 vested in full. In September 2009, an award of options 
was made to a non-executive Director of the Company (Mr Clegg) 
which was subject to a performance condition whereby if TSR during 
the three year period exceeded 30% then the award would vest if full. 
The actual TSR achieved was 110% and therefore the award vested in 
full. In October 2009, an award of options was made to a consultant 
to the Company with non-market performance conditions. These 
conditions were achieved in full and therefore this award has also 
vested in full.
(iv) Service contracts and letters of appointment
The executive Directors have entered into service agreements which can 
be terminated on six months’ notice by either party. 
During the year, Richard Marsden continued to act as a non-executive 

Director of Southampton Asset Management Limited but did not receive 
any fees with regards to this appointment. None of the other executive 
Directors held non-executive directorships with other companies. 
The Chairman and non-executive Directors have entered into letters of 
appointment for an initial fixed period of twelve months, which renew 
automatically for a further twelve month period on the anniversary of 
commencement. The appointment can be terminated on three months’ 
notice by either party.

Directors’ interests in share options
The interests of Directors in share options over ordinary shares during

Statement of Directors’ responsibilities in respect 
of the Annual Report and the Financial Statements

Website publication
The Directors are responsible for ensuring the annual report and 
financial statements are made available on a website. Financial 
statements are published on the Group's website in accordance with 
AIM rules for companies and legislation in the United Kingdom 
governing the preparation and dissemination of financial statements, 
which may vary from legislation in other jurisdictions. The 
maintenance and integrity of the Group's website is the responsibility 
of the Directors. The Directors' responsibility also extends to the 
ongoing integrity of the financial statements contained therein. 

Going concern
The Directors have prepared and reviewed financial forecasts. After 
due consideration of these forecasts and current cash resources, the 
Directors consider that the Company and the Group have adequate 
financial resources to continue in operational existence for the 
foreseeable future (being a period of at least twelve months from the 
date of this report), and for this reason the financial statements have 
been prepared on a going concern basis.

By order of the Board

John Ward 
Company Secretary

12 February 2013

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 period. Under that law the Directors have elected 
to prepare the Group financial statements in accordance with 
International Financial Reporting Standards (IFRSs) as adopted by the 
European Union and the Company financial statements in accordance 
with United Kingdom Generally Accepted Accounting Practice (United 
Kingdom Accounting Standards and applicable law). 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 Company and of the profit or loss of the Group for that period. 
The Directors are also required to prepare financial statements in 
accordance with the rules of the London Stock Exchange for companies 
trading securities on the Alternative Investment Market.  

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

•	  select suitable accounting policies and then apply them 

consistently;

•	  make judgements and accounting estimates that are reasonable 

and prudent;

•	  state whether they have been prepared in accordance with IFRSs 

as adopted by the European Union, subject to any material 
departures disclosed and explained in the financial statements; 
and

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

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

Independent Auditor’s Report 
to the members of Synairgen plc

We have audited the financial statements of Synairgen plc for the year 
ended 31 December 2012 which comprise the Consolidated Statement 
of Comprehensive Income, the Consolidated Statement of Changes 
in Equity, the Consolidated Statement of Financial Position, the 
Consolidated Statement of Cash Flows, the Parent Company Balance 
Sheet and the related notes. The financial reporting framework that 
has been applied in the preparation of the group financial statements 
is applicable law and International Financial Reporting Standards 
(IFRSs) as adopted by the European Union. The financial reporting 
framework that has been applied in preparation of the parent company 
financial statements is applicable law and United Kingdom Accounting 
Standards (United Kingdom Generally Accepted Accounting Practice).  
This report is made solely to the company’s members, as a body, in 
accordance with Chapter 3 of Part 16 of the Companies Act 2006. 
Our audit work has been undertaken so that we might state to the 
company’s members those matters we are required to state to them 
in an auditor’s report and for no other purpose. To the fullest extent 
permitted by law, we do not accept or assume responsibility to anyone 
other than the company and the company’s members as a body, for our 
audit work, for this report, or for the opinions we have formed.

Respective responsibilities of Directors and auditors
As explained more fully in the statement of Directors’ responsibilities, 
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). Those standards require 
us to comply with the Auditing Practices Board’s (APB’s) Ethical 
Standards for Auditors.   

Scope of the audit of the financial statements
A description of the scope of an audit of financial statements is provided 
on the APB’s website at www.frc.org.uk/apb/scope/private.cfm. 

Opinion on financial statements
In our opinion: 
•	 the financial statements give a true and fair view of the state of the 

group’s and the parent company’s affairs as at 31 December 2012 and 
of the group’s loss for the year then ended;

•	 the group financial statements have been properly prepared in 
accordance with IFRSs as adopted by the European Union;

•	 the parent company’s financial statements have been properly 

prepared in accordance with United Kingdom Generally Accepted 
Accounting Practice; and

•	 the financial statements have been prepared in accordance with the 

requirements of the Companies Act 2006.

Opinion on other matters prescribed by the Companies Act 2006
In our opinion the information given in the Directors’ report for the 
financial year for which the financial statements are prepared is 
consistent with the financial statements. 

Matters on which we are required to report by exception
We have nothing to report in respect of the following matters where the 
Companies Act 2006 requires us to report to you if, in our opinion:
•	  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; or

•	  certain disclosures of Directors’ remuneration specified by law are 

not made; or

•	  we have not received all the information and explanations we 

require for our audit.

Notes to the Consolidated Financial Statements 

for the year ended 31 December 2012

1. Accounting policies

Basis of preparation
The Group financial statements have been prepared in accordance with International Financial Reporting Standards as adopted by the 
European Union (Adopted IFRSs) and with those parts of the Companies Act 2006 applicable to companies preparing their financial 
statements under IFRSs.  
The following new standards, amendments to standards and interpretations that have been issued by the International Accounting 
Standards Board and the International Financial Reporting Interpretations Committee are to be applied to financial statements with 
periods commencing on or after the following dates:

International Accounting and Financial Reporting Standards (IAS/IFRS)

* Not endorsed by the European Union as at the date of approval of these financial statements.

The Directors anticipate that the adoption of these standards and interpretations in future periods will have no material impact on the financial 
statements of the Group.
The Group financial statements are presented in Sterling.

Basis of consolidation 
The consolidated financial statements incorporate the financial statements of the Company and entities controlled by the Company 
made up to the reporting date.  Control is achieved where the Company has the power to govern the financial and operating policies of an 
investee entity so as to obtain benefits from its activities. All intra-group transactions, balances, income and expenses are eliminated on 
consolidation. Business combinations that took place prior to 1 July 2006, the date of transition to IFRS, have not been restated as permitted 
by IFRS 1 “First-time Adoption of International Financial Reporting”. The consolidated financial statements have been prepared using the 
merger method of accounting.

Change of Accounting Reference Date in prior accounting period
During the prior accounting period the Group brought forward its financial year-end from 30 June to 31 December for administrative reasons 
to expedite the production of its annual report and accounts. As a result these financial statements cover the year ended 31 December 2012 
with comparative financial information being given for the six months ended 31 December 2011, and therefore the amounts presented in the 
financial statements are not entirely comparable.

Research and development
All ongoing research expenditure is currently expensed in the period in which it is incurred. Due to the regulatory and other uncertainties 
inherent in the development of the Group’s products, the criteria for development costs to be recognised as an asset, as set out in IAS 38 
“Intangible Assets”, are not met until a product has been submitted for regulatory approval and it is probable that future economic benefit 
will flow to the Group. The Group currently has no such qualifying expenditure.

Notes to the Consolidated Financial Statements 

for the year ended 31 December 2012 (continued)

1. Accounting policies (continued) 

Employee benefits
All employee benefit costs, notably salaries, holiday pay, bonuses and contributions to Group stakeholder or personal defined contribution pension 
schemes are charged to the consolidated statement of comprehensive income on an accruals basis.

Share-based payments
Option awards and awards made under the Group’s Long-Term Incentive Plan (‘LTIP’) granted after 7 November 2002 which had not vested by 
1 July 2006 are fair valued and charged to the consolidated statement of comprehensive income over the period from grant to vesting.  The Group 
has fair-valued option and LTIP awards using appropriate share valuation models. Options granted to non-employees are measured at the fair 
value of the goods or services received, except where the fair value cannot be estimated reliably, in which case they are measured at the fair value 
of the equity instrument granted. At each reporting date, the Group revises its estimate of the number of options that are expected to become 
exercisable. The credit for any charge is taken to equity. 

Intangible assets
Intangible assets are stated at cost less any accumulated amortisation and any accumulated impairment losses. Patent and licence costs 
are amortised over ten years on a straight-line basis and the amortisation cost is charged to research and development expenditure in the 
consolidated statement of comprehensive income. 

Property, plant and equipment
Property, plant and equipment are stated at cost less any accumulated depreciation and any accumulated impairment losses. Depreciation is 
provided on a straight-line basis at rates calculated to write off the cost of property, plant and equipment, less their estimated residual value over 
their expected useful lives, which are as follows:

Computer equipment: 
Laboratory and clinical equipment: 

3 years
5 years

The carrying values of property, plant and equipment are reviewed for impairment if events or changes in circumstances indicate that the 
carrying value may not be recoverable.

Inventories
Inventories are stated at the lower of cost and net realisable value.

Financial instruments
Financial assets and financial liabilities are recognised on the Group’s consolidated statement of financial position when the Group becomes a 
party to the contractual provisions of the instrument.

Financial assets
The Group classifies its financial assets as loans and receivables. These assets are non-derivative financial assets with fixed or determinable 
payments that are not quoted in an active market. They are initially recognised at fair value plus transaction costs that are directly attributable to 
their acquisition or issue, and are subsequently carried at amortised cost using the effective interest rate method, less provision for impairment. 
Impairment provisions are recognised when there is objective evidence (such as significant financial difficulties on the part of the counterparty 
or default or significant delay in payment) that the Group will be unable to collect all of the amounts due under the terms receivable; the amount of 
such a provision being the difference between the net carrying amount and the present value of the future expected cash flows associated with the 
impaired receivable.

The Group’s loans and receivables comprise trade and other receivables, other financial assets and cash and cash equivalents in the consolidated 
statement of financial position. Other financial assets comprise short-term deposits not meeting the IAS 7 definition of a cash equivalent. Cash 
and cash equivalents includes cash in hand, deposits held at call with banks and other short-term bank deposits with a maturity period of three 
months or less from the date of initial deposit.

Financial liabilities
The Group classifies its financial liabilities as financial liabilities held at amortised cost. Trade payables are initially recognised at fair value and 
subsequently carried at amortised cost using the effective interest rate method.

Leased assets
Where substantially all of the risks and rewards incidental to ownership are not transferred to the Group (an ‘operating lease’), the total rentals 
payable under the lease are charged to the consolidated  statement of comprehensive income on a straight-line basis over the lease term.

Notes to the Consolidated Financial Statements 

for the year ended 31 December 2012 (continued)

1. Accounting policies (continued) 

Taxation
Income tax is recognised or provided at amounts expected to be recovered or to be paid using the tax rates and tax laws that have been enacted or 
substantively enacted at the reporting date. Research and development tax credits are included as an income tax credit under current assets.
Deferred tax balances are recognised in respect of all temporary differences that have originated but not reversed by the reporting date except for 
differences arising on:

•	 investments in subsidiaries where the Group is able to control the timing of the reversal of the difference and it is probable that the 

difference could not reverse in the foreseeable future; and

•	 the initial recognition of an asset or liability in a transaction which is not a business combination and at the time of the transaction 

affects neither accounting or taxable profit.

The amount of the asset or liability is determined using tax rates that have been enacted or substantively enacted by the reporting date and are 
expected to apply when the deferred tax liabilities/(assets) are settled/(recovered).

Recognition of deferred tax assets is restricted to those instances where it is probable that a taxable profit will be available against which the 
temporary difference can be utilised. Deferred tax balances are not discounted.

Foreign currencies
Transactions entered into by Group entities in a currency other than the currency of the primary economic environment in which they operate 
(their "functional currency") are recorded at the rates ruling when the transactions occur. Foreign currency monetary assets and liabilities are 
translated at the rates ruling at the reporting date. Exchange differences arising on the retranslation of unsettled monetary assets and liabilities 
are recognised immediately in the consolidated statement of comprehensive income.
The functional currency of all entities in the Group is Sterling.

2. Critical accounting estimates and judgements
Critical accounting estimates, assumptions and judgements are continually evaluated by management based on available information and 
experience. As the use of estimates is inherent in financial reporting, actual results could differ from these estimates.

Inventory
The Group’s raw material inventory shown in note 11 comprises the Group’s biobank of human tissue, which is valued net of a provision for items 
which management consider will be excess to the Group’s future research and development requirements. Inventories have been written down by 
£9,000 during the year.

Share-based payment
The critical accounting estimates, assumptions and judgements underpinning the valuation of the option and LTIP awards are disclosed in note 17.

3. Segmental analysis

The Group operates in one area of activity, namely drug discovery and development. All assets of the Group are located within the United Kingdom 
and all losses were generated in that territory.

Deferred taxation

Changes in tax rates and factors affecting the future tax charge 
Finance Act 2012 includes provision for the main rate of corporation tax to reduce from 26% to 24% on 1 April 2012, and to 23% on 1 April 
2013. It has also been announced that there will be a further 1% reduction to bring the main rate to 22% from 1 April 2014. This will reduce the 
Company’s future tax charge accordingly. The rate of 24% was substantially enacted on the 26 March 2012 and the rate of 23% was substantially 
enacted on 6 July 2012. Accordingly, deferred tax balances have been recognised at 23%, the rate of corporation tax enacted in Finance Act 2012 
to apply from 1 April 2013.

Notes to the Consolidated Financial Statements 

for the year ended 31 December 2012 (continued)

7. Taxation (continued)

Unrecognised deferred taxation 
At 31 December 2012 the Group has trading losses carried forward which are available for offset against future profits of the Group amounting to 
£9,624,000 (31 December 2011: £8,424,000) and non-trading losses of £861,000 (31 December 2011: £635,000). At 31 December 2012 the Group 
has an unrecognised deferred tax asset in respect of these losses of £2,412,000 (31 December 2011: £2,265,000). The full utilisation of these 
losses in the foreseeable future is uncertain and no deferred tax asset has therefore been recognised.

The movement on the unrecognised deferred tax asset comprises the following:

Unrecognised deferred tax asset at the start of the period

Effect of tax rate change

Movement in period

Unrecognised deferred tax asset at the period-end  

8. Loss per ordinary share

The loss attributable to ordinary shareholders and weighted average number of ordinary shares for the purpose of calculating the diluted 
earnings per ordinary share are identical to those used for basic earnings per share. This is because the exercise of share options would have the 
effect of reducing the loss per ordinary share and is therefore not dilutive under the terms of IAS 33. At 31 December 2012, there were 7,511,635 
options outstanding (31 December 2011: 7,911,787 options outstanding) as detailed in note 17.

16. Financial instruments (continued)

The objective of holding financial instruments is to have access to finance for the Group’s operations and to manage related risks. The main risks 
arising from holding these instruments are interest rate risk, liquidity risk, and credit risk.   

Interest rate risk
Interest rate risk profile of financial assets, excluding short-term debtors:

Floating-rate financial assets comprise cash on deposit and cash at bank. There is no difference between the carrying amount and the fair value 
of the financial assets.

Short-term deposits are placed with banks for periods of up to twelve months and are categorised as floating-rate financial assets. Contracts 
in place at 31 December 2012 had a weighted average period to maturity of 48 days and a weighted average annualised rate of interest of 1.09% 
(31 December 2011: 83 days, 1.31%).

Sensitivity analysis
It is estimated that a decrease of half of one percentage point in interest rates would have increased the Group’s loss before taxation by 
approximately £16,000 (six months ended 31 December 2011: £11,000). 

Liquidity risk
The Group’s policy is to maintain adequate cash resources to meet liabilities as they fall due. All Group payable balances as at 31 December 2012 
and 31 December 2011 fall due for payment within one year. Cash balances are placed on deposit for varying periods with reputable banking 
institutions to ensure there is limited risk of capital loss. The Group does not maintain an overdraft facility.

Credit risk
The Group’s credit risk is attributable to its banking deposits. The Group places its deposits with reputable financial institutions to minimise 
credit risk.

In accordance with IFRS 2, the Company has applied IFRS 2 to all share-based payments granted after 7 November 2002 which had not vested by 
1 July 2006. The following comments apply to those options which have been fair valued in accordance with IFRS 2.

(i)  Stochastic valuation methodology was used for the LTIP awards and the QNEOS awards with market performance conditions and Black-Scholes methodology for the other awards.

(ii)  Expected dividend yield is nil, consistent with the Directors’ view that the Group’s model is to generate value through capital growth rather than payment of dividends.

(iii)  The risk free rate is equal to the prevailing UK Gilts rate at grant date that most closely matches the expected term of the grant.

(iv)  The fair value charge is spread evenly over the expected vesting period. 

(v)  The charge for the year ended 31 December 2012 for share-based payment amounted to £193,000 (six months ended 31 December 2011: £96,000).

18. Capital and reserves

18a Share capital 
Share capital represents the nominal value of shares issued.

18b Share premium
Share premium represents amounts subscribed for share capital in excess of nominal value less the related costs of share issues.

18c Merger reserve
The merger reserve represents the reserve arising on the acquisition of Synairgen Research Limited on 11 October 2004 via a share for share 
exchange accounted for as a Group reconstruction using merger accounting under UK GAAP.

18d Retained deficit
The retained deficit represents cumulative net gains and losses recognised in the consolidated statement of comprehensive income, adjusted for 
cumulative recognised share-based payments.

19. Related party transactions and balances

During the year ended 31 December 2012, the Group incurred consultancy fees with Prof. Stephen Holgate, a Director of the Company, amounting 
to £11,000 (six months ended 31 December 2011: £5,000) in addition to his Director’s remuneration disclosed on page 22. At the reporting date, the 
amount unpaid in respect of these charges was £11,000 (31 December 2011: £1,000).
During the year ended 31 December 2012, the Group incurred consultancy fees with Ms Emma Toman, partner of Richard Marsden, a Director of 
the Company, amounting to £1,000 in connection with risk assessments (six months ended 31 December 2011: £nil). At the reporting date, there was 
no amount unpaid in respect of these charges (31 December 2011: £nil). 
Details of key management personnel and their compensation are given in note 5 and on page 22 of the Directors’ Remuneration Report.

Notes to the Parent Company Financial Statements 

for the year ended 31 December 2012 

1. Basis of preparation

Synairgen plc’s Parent Company balance sheet has been prepared under the historical cost convention and in accordance with UK Generally 
Accepted Accounting Practice (‘UK GAAP’). 

As permitted by FRS 1 “Cash Flow Statements”, no cash flow statement for the Company has been included on the grounds that the Group 
includes the Company in its own published consolidated financial statements. The Company has taken advantage of the exemption in FRS 8 
“Related Party Disclosures” not to disclose related party transactions with wholly-owned subsidiaries.

2. Accounting policies

The following accounting policies have been applied consistently in dealing with items which are considered material to the Company’s 
financial statements.

Investment in subsidiary undertakings
Investments in subsidiary undertakings where the Company has control are stated at cost less any provision for impairment. Control is 
achieved where the Company has the power to govern the financial and operating policies of an investee entity so as to obtain benefits from 
its activities.

Short-term deposits
Short-term deposits comprise deposits with UK banks for periods of up to twelve months. Short-term deposits are measured initially at cost 
and subsequently at cost or recoverable amount if lower. Interest is accrued evenly on an accruals basis.

Share-based payments
In accordance with FRS 20, when the Company grants options over equity instruments directly to the employees of a subsidiary 
undertaking, the effect of the share-based payment  is capitalised as part of the investment in the subsidiary as a capital contribution, 
with a corresponding increase in equity.

Taxation
The charge for taxation is based on the loss for the period and takes into account taxation deferred.
Current tax is measured at amounts expected to be paid using the tax rates and laws that have been enacted or substantively enacted by the 
balance sheet date. Deferred tax balances are recognised in respect of all timing differences that have originated but not reversed by the 
balance sheet date, except that the recognition of deferred tax assets is limited to the extent that the company anticipates making sufficient 
taxable profits in the future to absorb the reversal of the underlying timing differences.
Deferred tax balances are not discounted.

3. Loss attributable to member of the Parent Company

As permitted by Section 408 of the Companies Act 2006, the Company’s profit and loss account has not been included in these financial 
statements. The loss dealt with in the financial statements of the Parent Company for the year ended 31 December 2012 was £225,000 
(six months ended 31 December 2011: loss of £113,000).

4. Directors’ remuneration

The only employees of the Company are the executive Directors and all their costs are borne by its subsidiary undertaking.
In respect of Directors’ remuneration, the disclosures required by Schedule 5 to the Large and Medium-sized Companies and Groups 
(Accounts and Reports) Regulations 2008 are included in the detailed disclosures in the audited section of the Directors’ Remuneration 
Report on page 22, which are ascribed as forming part of these financial statements.

Synairgen is a respiratory drug discovery  
and development company with a focus on viral 
defence of the lungs. It is developing inhaled 
interferon beta (‘IFN-β’) in two programmes:
• To prevent asthma and COPD patients 

suffering severe exacerbations as a result  
of cold or flu infections

• To treat other patients who have been 

hospitalised with severe viral lung infections

Patents protecting the use of inhaled iFN-β to treat exacerbations 
of asthma and CoPD induced by rhinovirus (the common cold) 
have been granted in the USA, the EU and Japan.

in 2012 Synairgen announced positive data from its Phase ii 
proof of concept trial of inhaled iFN-β in asthma and is 
aiming to secure the right partnership arrangement to enable 
commencement of follow-on clinical trial activity during the 
2013-14 virus season.

Exacerbations (acute deteriorations of symptoms) represent the 
greatest unmet clinical need in asthma and CoPD. The common 
cold plays a major role in exacerbations, causing up to 80% of 
asthma exacerbations. For CoPD patients 50% of colds result 
in exacerbations. The annual direct healthcare cost of treating 
asthma and CoPD is very significant. in the USA it amounts 
to $54 billion1, of which $16 billion is for hospitalisations and 
Emergency Room visits.

Viruses are parasites which take over cells and use the cells’ 
‘machinery’ to replicate. The normal host cell response to viral 
infection is to trigger iFN-β production, which in turn orchestrates 
an anti-viral response (see page 10). Deficiencies in iFN-β 
production following infection explain why some patient groups 
(such as those with asthma and CoPD) are more susceptible to 
infection. many pathogenic respiratory viruses, such as  
influenza and SARS, can suppress iFN-β production, allowing 
infections to spread to the lungs and cause severe illness.

By delivering iFN-β to the lungs, Synairgen aims to overcome 
the iFN-β deficiency and restore/boost the lungs’ anti-viral 
defence mechanism.
