Vision
Global market leader of next generation cyber-threat defence products and services that enable 
Enterprise, Government and Cloud Service Providers to combat increasingly sophisticated 
unwanted network traffic to protect and optimise Internet facing businesses and organisations.

Market dynamics
Society’s increasing reliance on the Internet has streamlined 
business efficiency and led to booming online revenue growth. 
Online sales, on what is termed in the United States Cyber 
Monday (November 26, 2012), approached $1.5 billion, up 30% 
from sales on the same day in 2011. This growth in online sales 
has created an explosion of cyber-attack entrepreneurs – 
looking to cash in on the growing digital marketplace.

According to the 2012 Verizon Data Breach Investigations 
Report, the number of compromised records skyrocketed to 
174 million. It also found that external attackers were behind 
the majority (98%) of breaches. As the number of attacks 
increase, so do the financial consequences. Research 
published by the Ponemon Institute found a 42% increase in 
the number of cyber-attacks, with the average annualised cost 
of cyber-crime incurred by a benchmark sample of US 
organisations of $8.9 million. It noted that organisations 
experienced an average of 102 successful attacks per week, 
compared to 72 attacks per week in 2011. It cited distributed 
denial of service (DDoS) as a common attack type and one of 

the most costly cyber-crimes. With the growing number of 
attacks, the DDoS protection market is forecast to grow by 
16% per annum to $485 million by 2016 (Infonetics Research).

With the number of successful attacks on the rise it is evident 
that existing firewall, intrusion prevention systems, and 
traditional security infrastructure are not equipped to combat 
them. These technologies were not built to stop many of 
today’s attacks and are being overwhelmed by DDoS attacks, 
advanced evasion techniques, server side exploits and other 
unwanted traffic. Organisations will need to adopt a first line 
of defence to effectively combat these attacks which are 
increasing in number and sophistication.

Technology for Today’s Problems,  
Tomorrow’s Challenges
As an organisations First Line of Defense, Corero’s products 
and services stop unwanted traffic including DDoS attacks 
and intrusions at the perimeter to protect IT infrastructure, 
eliminate downtime and ensure the uninterrupted flow of 
revenue generating traffic.

Corero’s First Line o f Defense

Corero’s First Line of Defense defines  
the network perimeter to be in front of the 
firewall. The First Line of Defense stops 
increasingly sophisticated unwanted 
traffic, which is intended to flood or 
otherwise harm the IT infrastructure, 
before it hits the firewall. This ensures 
availability for legitimate users.

This First Line of Defense provides 
deep-packet inspection to dynamically 
detect and stop flooding attacks, 
server-targeted malware and other 
exploits designed to compromise 
systems or access sensitive and 
confidential data.

Organisations need to shore up their network perimeter with a new security device, purpose built to detect and stop 
unwanted traffic before it can overrun the firewall and expose IT infrastructure to performance issues, compromise  
or catastrophic failures.

Presentation currency

Subsequent to the acquisition and 
integration of the US based Corero 
Network Security division (formerly  
Top Layer Networks) during 2011, the 
Group’s presentation currency has  
been changed to US Dollars (“$”) which 
is more closely aligned to the profile of 
the Group's revenue and cost base. The 
change is effective from 1 January 2012 
and thus the results for the 12 months 
ended 31 December 2012 are reported  
in $. The average $-GBP sterling  
(“GBP”) exchange rate, used for the 
conversion of the statement of 
comprehensive income, for the 12 
months ended 31 December 2012 was 
1.59 (2011: 1.60). The closing $-GBP 
exchange rate, used for the conversion 
of the Group’s assets and liabilities, at  
31 December 2012 was 1.63 (2011: 1.55). 

Results highlights

In the year ended 31 December 2012 
the Group reported revenues of $20.6 
million (2011: $18.0 million) and an 
EBITDA loss before depreciation, 
amortisation, acquisition and 
restructuring costs and financing of  
$3.1 million (2011: profit $0.4 million).

the progress made in the product 
development, marketing and operational 
aspects of the business in 2012. 

In September 2012, CNS launched  
its “First Line of Defense” solution  
to leverage its industry leading 
Distributed Denial of Service  
(“DDoS”) protection and intrusion 
prevention technology. Sales order 
intake (bookings as opposed to 
amounts recognised as revenue) 
in the 12 month period ended 
31 December 2012 was $10.4 million 
(2011: $12.0 million). Sales order intake 
was impacted by the repositioning of 
the CNS division around its new First 
Line of Defense solution in the second 
half of the year. 

In 2012, 44 new partners were recruited 
bringing the total number of partners at 
31 December 2012 to over 80. The First 
Line of Defense positioning has been 
well received by important new 
customers and partners as a compelling 
and differentiated offering. 

Ashley Stephenson, who joined CNS in 
March 2012 as Executive Vice President 
Product Marketing and Strategy, was 
appointed Chief Executive Officer of the

The security market dynamics 
and opportunity for Corero 
Network Security

The market demand for security 
products and services continues to be 
driven by the growing threat landscape 
and increasingly influenced by the 
more widespread attack patterns. 
Organisations globally have to face 
constant threats originating from 
economically, criminally and politically 
motivated cyber attackers, with an 
increasing business impact as 
organisations become commercially 
more reliant on the Internet. The huge 
growth in online business and Internet 
financial transactions has created an 
explosion of cyber-attack entrepreneurs 
looking to cash in on the burgeoning 
digital marketplace.

•    According to a 

PriceWaterhouseCoopers survey 
published in April 2012, most 

companies had a security breach in 
2011 with the level of attacks double 
that in 2010 (organisations had an 
average of 54 significant attacks by 
an unauthorised outsider in 2011). 

There is heightened awareness in 
governments to the increasing cyber 
security challenge which is driving 
awareness in both commercial and 
government organisations:

•    Research published by the 

•    UK Cabinet Office minister Francis 

Ponemon Institute found that 
occurrences of cyber-attacks is 
mounting, with a 42% increase in 
the number of cyber-attacks in 
2011. The research reported an 
average annualised cost of cyber 
crime incurred by a benchmark 
sample of U.S. organisations of 
$8.9 million. It also noted that 
organisations experienced an 
average of 102 successful attacks 
per week, compared to 72 attacks 
per week in 2010. It cited DDoS as 
a common attack type and one of 
the most costly cyber crimes.

•    Forrester research shows DDoS 
protection is one of the top five 
security technology growth 
opportunities for the next three years 
given the increase in hactivism.

•    A December 2012 Ponemon Institute 
survey of 350 retail banks revealed 
that 64% of banks were hit by at 
least one DDoS attack in the past 12 
months (48% hit by multiple DDoS 
attacks) and that 78% of banks 
expect that attacks will continue or 
significantly increase.

Maude commented in his December 
2012 Cabinet office statement “The 
Internet has revolutionised the way 
we do business and is driving 
growth – the UK’s Internet-related 
market is now worth £82 billion a 
year and this is set to rise. Cyber-
attacks are one of the top four 
threats to our national security and 
cyber crime is costing our economy 
billions of pounds a year. And as 
businesses and government move 
more of their operations online, the 
scope of potential targets will 
continue to grow. It’s a race: to build 
sufficient cyber defences to match 
the growing volume and 
dependence of our online economic, 
security and social interests.”

•    The Obama administration has 
recently urged organisations to 
implement stronger firewalls and 
other systems to provide a first line 
of defence for better resiliency to 
cyber-attacks.

In the last year there has been a 
significant increase in unwanted, 
suspicious and malicious traffic arriving 

“Resource 32000 is a system that is user friendly,  
and comprehensive enough to meet all our reporting 
requirements including fulfilling companies house 
accounts regulations.”

being overwhelmed by DDoS attacks, 
advanced evasion techniques, server 
side exploits and other unwanted 
traffic. As a result, a market is 
emerging for new security solutions 
that are deployed in front of the 
traditional firewalls, with the primary 
business driver being DDoS protection. 

Corero has a first mover advantage in 
this market - and plans to reinforce this 
advantage through its investment in a 
next generation product to establish a 
leadership position. With the increase in 
the prevalence of malicious activity - 
particularly DDoS attacks - 
organisations, most notably in financial 
services and ecommerce verticals, are 
starting to include DDoS protection 
investment in their IT security budgets. 
Research by Forrester confirms that 
42% of organisations expect to increase 
network security spend in 2013 with 
24% of security budgets allocated to 
network security. The DDoS prevention 

appliance market is forecast by 
Infonetics to grow from $270 million  
in 2012 to $485 million in 2016.

Corero Business Systems review

Revenues for the CBS division 
increased by 30% in 2012 to $9.2 million 
(2011: $7.0 million). CBS sales order 
intake in the year to 31 December 2012 
was $10.5 million (2011: $8.1 million). 

CBS reported an EBITDA profit before 
depreciation, amortisation, acquisition 
and restructuring costs and financing  
of $3.1 million (2011: $2.6 million).

The CBS division won new contracts 
from 251 academies and schools in the 
12 months ended 31 December 2012 
(2011: 192) for its Resource Financials  
& HR software solution, underlying its 
strong position in this growth market. 
In addition, despite the tight Public 
Sector spending environment, CBS 
won 3 new contracts (2011: 3) from 
sixth form colleges in the 12 months 
ended 2012 for its Resource EMS 
learner management system. 

Key achievements in 2012 include:

•    Expansion of schools managed by 
Multi Academy Trust customers: The 
Kemnal Academies Trust adding 24 
schools and the School Partnership 
Trust adding 15 schools. 

•    New academy trust groups signed 
including: REACH 2, Outwood 
Grange Academy Trust and London 
Diocesan Board for Schools. 

•    Appointment of Mike Stansfield as 
Product Development Director who 
brings 25 years’ IT industry 
experience with leading companies 
such as Taxsoft, Sage, QSA and 
Pitney Bowes. 

•    CBS’ Resource Financials product 
was announced as the winner of  
The UK Business Software Industry 
Software Satisfaction Awards 2012 
(“SSA12”) in its category.

•    Achieved full ISO9001 

Accreditation status. 

The UK education market 
dynamics and opportunity  
for Corero Business Systems

The key growth market for Corero 
Business Systems is the schools market 
(including academies and free schools). 
The academy conversion programme is 
a key part of the Government’s 
education policy. As of 1 January 2013, 
only 12% of the 21,000 schools in 
England were academies. 

There continues to be strong interest 
from Local Education Authority 
controlled schools to convert to 
academies, encouraged by The 

 “We’re very security conscious. We take our responsibility to protect  

our customers’ data very seriously. One of our key criteria was  
inspected throughput for the invested dollar. Corero meets our  
demanding requirements, including the need for very low latency.”

the emergence of academy groups 
including CBS customers, the School 
Partnership Trust (based in Leeds) and 
The Kemnal Academies Trust (based in 
Kent), each with 30 and 32 academies 
respectively at 31 December 2012. 

Business strategy

The Corero Network Security division's 
strategy is aimed at exploiting the 
opportunity to provide cyber security 
attack mitigation defences in a rapidly 
growing market, including DDoS 
protection products configured for 
either on-premise or cloud solutions. If 
CNS can capitalise on this exploding 
opportunity, with its recently launched 
and differentiated First Line of Defense 
offering, we would expect to see strong 
revenue growth emerging from 2013 
and beyond.

CNS is also investing in a next 
generation product to increase its 
addressable market. This product, the 
initial release of which is anticipated for 
later in 2013, is aimed at extended 
deployments in cloud infrastructure, 
virtual environments, and in very large 
scale networks. 

The strategy for the Corero Business 
Systems division is to continue to invest 
for growth and remain focused on the 
education sector where the business has 

a strong market position, particularly in 
the further education college and 
academy and schools markets in 
England. The potential also exists to 
consider expansion into international 
markets. The CBS division plans to make 
further investment in its existing products, 
including plans for a Software-as-a-
Service (Saas) enabled finance software 
product. These plans will be funded from 
existing resources and the on-going 
profitable trading of the division.

The Group will continue to manage and 
operate as two separate divisions with a 
small central head office overhead.

Staff

Our employees include highly skilled 
developers, and experienced 
management, sales executives and 
support staff, all focused on delivering 
market leading solutions to our 
customers. On behalf of the Board, I 
would like to thank the employees of 
Corero for their efforts in the last 
financial year.

Directorate

I would like to thank Edward Forwood  
and Stephen Graham who resigned 
from the Board in March and June 2012 
respectively, for their contribution  
and welcome Andrew Lloyd who  
was appointed to the Board in 
November 2012.

Outlook

Significant progress has been made in 
the Corero Network Security business. 
The business and management team 
have been reorganised and the 
groundwork laid to drive incremental 
growth in new international markets. This 
division is well positioned to deliver 
growth in 2013. Corero Network Security 
has had an encouraging start to 2013 with 
material business wins generated from 
both new and existing customers. New 
customer wins include: a US utility, a 
leading mobile service provider in Brazil, 
and an Internet domain services 
company. Existing customer renewals 
include a leading European lottery 
operator, one of the largest insurers in the 
United States, and a leading price 
comparison web site.

The Corero Business Systems division 
performed strongly in 2012 with this 
growth expected to continue. The 
division plans to make further self-
funded investments in its products  
and to consider adjacent market 
opportunities. Corero Business Systems 
has had an encouraging start to 2013.

Financial performance

Performance indicators

For the year ended 31 December 2012, 
the Group reported an EDITDA loss 
before depreciation, amortisation, 
acquisition and restructuring costs and 
financing of $3.1 million (2011: profit 
$0.4 million) and a loss after taxation of 
$5.9 million (2011: $2.0 million). This 
included an unrealised exchange loss of 
$0.3 million (2011: $0.1 million) arising 
on an intercompany loan.

Central costs were $1.2 million (2011: 
$1.2 million) which relate to the Group's 
finance and administration functions as 
well as the costs associated with the 
Company’s listing on AIM. 

Interest costs were $0.5 million (2011: 
$0.4 million) comprising interest on the 
Loan Notes issued by Top Layer 
Networks, Inc. ("Top Layer" subsequently 
renamed Corero Network Security, Inc.) 
as part of the purchase consideration 
for Top Layer and the Corero Network 
Security working capital facility. 

Interest received was $0.1 million  
(2011: $0.1 million).

The loss per share was 9.7 cents  
(2011: 5.3 cents). 

The Group’s net assets at the year end 
were $19.3 million (2011: $17.8 million).

The directors and managers of the 
Group monitor a number of metrics, 
both financial and non-financial, on a 
monthly basis. The most important of 
these are as follows:

•    Revenue: $20.6 million for the year 
ended 31 December 2012 (2011: 
$18.0 million);

•    Gross margin: 75% for the year ended 
31 December 2012 (2011: 77%);

•    Number of employees: 152 at 31 
December 2012 (2011: 130); and

•    Cash: $4.9 million at 31 December 

2012 (2011: $6.7 million)

Whilst the CNS division’s sales growth 
in 2012 (revenue $11.4 million compared 
to $11.0 million in 2011 for the 10 month 
period from the 2 March 2011 
acquisition date) was disappointing, we 
are confident that the progress and 
investment made in the business, the 
Q3 2012 positioning of CNS’ proposition 
as a First Line of Defense and the 
appointment of Ashley Stephenson as 
Chief Executive Officer to drive forward 
its sales-led growth strategy, have 
positioned the business well for the 
future. Despite revenue being below 
expectations, CNS continued its 
investment in product development  

and in the third quarter of 2012 
commenced the development of its  
next generation product as the Board 
believes this investment is important for 
CNS to increase it addressable market 
and revenue in the future. Operating 
expenses increased from $9.2 million in 
2011 (a 10 month period) to $13.2 million 
in 2012 predominantly as a result of the 
increase in headcount from 73 
employees at 31 December 2011 to  
90 employees at 31 December 2012  
and the full year impact of the increase 
in headcount of 19 employees in the 
second half of 2011. The lower revenue 
growth and continued investment 
resulted in an operating loss of  
$7.4 million for the year ended  
31 December 2012 (2011: $2.6 million).

The CBS division delivered strong 
profitable growth in 2012 (revenue 
$9.2 million compared to $7.0 million in 
2011). Operating expenses increased 
from $3.1 million in 2011 to $4.1 million 
in 2012 predominantly as a result of the 
increase in headcount from 53 employees 
at 31 December 2011 to 58 employees 
at 31 December 2012 and the full year 
impact of the increase in headcount  
of 15 employees in the second half of 
2011. CBS reported an operating profit 
of $2.7 million for the year ended 
31 December 2012 (2011: $2.2 million).

 “Corero is the new IT perimeter. Adding it to our arsenal of best-of-breed offerings 
perfectly rounds out our network security portfolio. By stopping all the known and 
unknown traffic at the perimeter, Corero’s solutions guarantee uptime while ensuring 
our customers’ are able to maximize their existing IT infrastructure investment, from 
their next generation firewalls to their IPS devices, and remain secure.”

Cash and treasury 

The closing cash balance was 
$4.9 million (2011: $6.7 million). The  
net reduction in cash from operating 
activities was $5.1 million (2011: 
$1.6 million).

In 2012, the Company raised $7.2 million 
(£4.6 million) (before expenses) of which 
the directors and senior management 
contributed $2.2 million (£1.4 million).

At the end of the year, the Group had 
aggregate banking facilities of $2.8 
million which are committed for a period 
of one year and are repayable on 
demand. Group companies have 
complied with the financial covenants 
relating to these facilities.

Taxation

As a result of losses carried forward in 
the UK subsidiary and losses in the US 
acquired through the acquisition of Top 
Layer, the Group does not expect to pay 
the full rate of UK or US corporation tax 
for a number of years.

At 31 December 2012, the Group had 
unutilised tax losses carried forward of 
approximately $37.7 million (2011: $31.4 
million). This comprised UK tax losses of 
$10.0 million and US tax losses of $27.7 
million. $4.2 million of the tax losses 
relates to US capitalised R&D 

deductions which will be available at an 
accelerated level for 4 years. $9.0 million 
of the tax losses relate to pre-acquisition 
US tax losses which can be offset 
against taxable profits over 19 years 
(there is a limit on the utilisation of 
pre-acquisition tax losses of $0.7 million 
per annum and any unused loss may be 
carried forward to subsequent periods). 
Given the varying degrees of uncertainty 
as to the timescale of utilisation of these 
losses, the Group has not recognised 
$11.6 million of potential deferred tax 
assets associated with these losses.

Dividends

The Board is not recommending the 
payment of a dividend (2011: nil).

Principal risks and uncertainties

The Directors believe the following risks 
to be the most significant for the Group. 
However, the risks listed do not 
necessarily comprise all those 
associated with the Group. In particular, 
the Group’s performance may be 
affected by changes in market or 
economic conditions and in legal, 
regulatory and tax requirements. If any  
of the following risks were to materialise, 
the Group’s business, financial condition, 
results or future operations could be 
materially adversely affected. Additional 
risks and uncertainties not presently 

known to the Directors, or which the 
Directors currently deem immaterial,  
may also have an adverse effect upon 
the Group.

1. Competition

The Group operates in competitive 
markets with Corero Network Security 
and Corero Business Systems business' 
main competitors being much larger 
companies with significant financial 
resources. The Group has experienced, 
and expects to continue to experience, 
competition from a number of companies. 
This competition may take the form of 
new products and services to better 
meet industry needs and to enable 
competitors to respond more quickly  
to client requirements. Further, if the 
market for the Group’s products does 
not develop as it expects or if it fails  
to respond to market and competitive 
developments, the Group’s business 
and prospects could be materially 
adversely affected.

The network security market, in 
particular, is becoming increasingly 
competitive and the Group may face 
significant competition, including from 
competitors who have greater capital 
resources than the Group. There is no 
assurance that the Group will be able to 
compete successfully in such a market 
place. The Board is aware of this threat 

“The beauty of Resource for me is that it is an extremely 
powerful and flexible system that is also very easy to 
understand and use.”

Andrew Miller 
COO and Executive Director

and intends to continue to invest in the 
enhancement of the Group’s products 
and services. 

A careful watching brief is maintained on 
competitors to enable the Group to react 
quickly to any change in circumstance or 
technical developments.

2. Technology and  
market requirements

The markets the Group operates in  
are fast changing, driven by changing 
customer requirements and technology 
trends. As such the Group’s solutions 
require on-going development and 
enhancement to meet the needs of 
customers in its target markets. The 
Group’s ability to anticipate changes in 
technology and customer requirements 
and to develop successfully and 
introduce new and enhanced solutions 
on a timely basis will be significant 
factors in the Group’s ability to grow 
and remain competitive. 

The ability of the Group to invest in  
such development is dependent on  
new business generation and future 
cash flows. There can be no assurance

that the Group will have sufficient 
resources to make such investments, 
that these investments will bring the full 
advantages or any advantage as 
planned or that it will not encounter 
technical or other difficulties that could 
delay the introduction of new 
technologies or enhancements in the 
future. The Group’s failure, for 
technological or other reasons, to 
develop in a timely manner, and market, 
products or services incorporating new 
technologies could have a material 
adverse effect on its revenues, results 
of operations and/or prospects.

3. Technology Partners

Corero Network Security’s First Line  
of Defense solutions utilise a multi-core 
processing chip produced by Tilera 
Corporation. Should the supply of 
these chips by Tilera Corporation be 
interrupted or if this relationship was 
lost, this could result in a material 
adverse impact on the Group’s 
financial performance. The Group 
maintains a close relationship with 
Tilera Corporation to reduce the risk  
of loss of this relationship.

4. Key management

The Group depends on the recruitment 
and retention of the services of its key 
technical, sales, marketing and 
management personnel. Competition 
for such personnel can be intense, and 
the Group cannot give assurances that 
it will be able to attract or retain such 
staff. The Group seeks to address this 
risk by ensuring that suitable and 
competitive remuneration structures  
are in place.

6. Dependence upon key 
intellectual property

The Group’s success depends in part 
on its ability to protect its rights in its 
intellectual property. The Group relies 
upon various intellectual property 
protections, including patents, 
copyright, trademarks, trade secrets 
and contractual provisions to preserve 
its intellectual property rights. Despite 
these precautions, it may be possible 
for third parties to obtain and use the 
Group’s intellectual property without 
its authorisation and as such the 
Group may become involved in 
litigation which could be costly  
and time consuming. 

“DDoS attacks cost us thousands of dollars an hour. 
It’s all the money that players can’t spend and we can’t 
get. [With Corero] DDoS doesn’t affect us the way 
it used to. Without Corero, we would be seeing slow 
response times. But now it doesn’t get to that point.”

dilutive to shareholders. There can be no 
assurance that such funding, if required, 
will be available to the Company.

Andrew Miller

Director 
25 March 2013

7. System failures and breaches  
of security

The successful operation of the Group’s 
business depends upon maintaining the 
integrity of the Group’s computer, 
communication and information 
technology systems which are 
vulnerable to damage, breakdown or 
interruption from events which are 
beyond the Group’s control. All systems 
are backed up on a regular basis and 
appropriate investment is made in 
systems infrastructure within the Group 
to maintain appropriate standards of 
integrity and security.

8. Further issues of Ordinary  
Shares and access to finance

It may be necessary for the Company to 
raise additional capital by way of the 
further issue of ordinary Shares to 
enable the Group to progress through 
further stages of development. Any 

“We had a high-profile Wall Street firm that was under constant DDoS attack  
with more than 10,000 attackers at one point hitting them from almost every 
country in the world, overtaxing their firewall and bringing their sites to a 
standstill. None of their clients were able to access any of their websites.  
They were, to say the least, not happy. Though the firewall vendor had claimed  
to offer DDoS protection we quickly learned that this was not the case. We 
needed something that was specifically designed to handle this type of traffic. 
The Corero First Line of Defense product was installed and within hours the 
attacks were mitigated and the site performance returned to normal.”

Directors’ Report

for the year ended 31 December 2012

Principal activities

The principal activity of the Group during the year ended 31 December 2012 was the supply of security products and services  
to international customers and the supply of finance and management information software solutions to the UK education and 
commercial markets.

A review of the Group’s performance is disclosed within the Chairman’s Statement and the Financial Review.

Business review

The information satisfying the business review requirements is set out in this report: the Chairman’s Statement on pages 6  
to 9; the Financial Review on pages 10 to 13; the review of the principal risks and uncertainties on pages 11 to 13; all of which 
are incorporated into this report by reference. The Corporate Governance report forms part of this Directors’ report  
and is incorporated into it by reference.

Group results

The Group’s Statement of Comprehensive Income on page 25 shows a loss for the year of $5.9 million (2011: $2.0 million).

Going concern

The financial position, cash flows and borrowing facilities are described in the Financial Review on pages 10 to 13. 

Forecasts and projections, taking into account reasonably possible changes in trading performance, show that the  
Company and Group will be able to operate within the level of current cash balances and facilities.

The Directors are satisfied, in view of the cash reserves of $4.9 million (2011: $6.7 million) held on the balance sheet at  
31 December 2012, and the $6.2 million (before costs) raised from the March 2013 share issue, that the Company and the  
Group have adequate resources to continue operating for the foreseeable future. For this reason the going concern basis  
has been adopted in preparing the accounts.

Dividends

The Directors have not recommended a dividend (2011: £nil). 

Post balance sheet event

On 20 March 2013 the Company raised $6.2 million (£4.1 million) (before costs), of which the directors contributed $4.2 million 
(£2.8 million), by way of a placing of 27,000,004 new ordinary shares at a price of 15p per share, to support the investment in  
the Corero Network Security business’ next generation product.

Share capital

The issued share capital of the Company together with details of movements in the Company’s issued share capital during the 
financial period are shown in note 25 to the financial statements. As at the date of this report, 85,637,416 ordinary shares of 1p 
each (‘ordinary shares’) were in issue and fully paid with an aggregate nominal value of $1.3 million.

The market price of the ordinary shares at 31 December 2012 was 32.5p and the shares traded in the range 29.5p to 60.5p 
during the year.

Issue of shares

At the AGM held on 7 June 2012 shareholders granted authority to the Board under the Articles and section 551 of the 
Companies Act 2006 (the ‘Act’) to exercise all powers of the Company to allot relevant securities up to an aggregate nominal 
amount of £194,431. It is proposed at the forthcoming AGM to renew the authority to allot relevant securities up to an aggregate 
nominal amount of £285,458, being one-third of the nominal value of the current issued share capital.

Also at the AGM held on 7 June 2012, shareholders granted authority to the Board under the Articles and section 570(1) of the  
Act to exercise all powers of the Company to allot equity securities wholly for cash up to an aggregate nominal amount of £87,494 
without application of the statutory pre-emption rights contained in section 561 (1) of the Act. It is proposed at the forthcoming

The biographical details of the current Directors of the Company are given on pages 14 and 15.

Jens Montanana, Andrew Miller and Richard Last hold share options, details of which are shown in note 30 to the  
Financial Statements. 

Payment of suppliers

It is Group policy to agree and clearly communicate the terms of payment as part of the commercial arrangements negotiated 
with suppliers and then to pay according to those terms based upon the satisfactory completion of contractual obligations and 
timely receipt of an accurate invoice. The creditor days outstanding (based on the count back method) at 31 December 2012 
was 28 days (2011: 29 days). 

Environment

The Group’s activities are primarily office based and as such the directors believe that there is no significant environmental 
impact arising from the Group’s activities. No environmental performance indicators are therefore included within this report. 
The Group’s environmental policy states: “We endeavour to recycle appropriate materials where possible and to efficiently use 
natural resources and energy supplies so as to minimise our environmental impact. We will comply with the relevant statutes  
and legislation. Furthermore employees are encouraged to be environmentally aware. Company cars are not provided.”

Research and development

The development of computer software is an integral part of the Group’s business and the Group continues to develop its  
core software in response to user demand, and particularly the changing IT security threat landscape, and changes in software 
technology. During the year the Group enhanced its existing products and developed new products. A capital investment of  
$3.2 million (2011: $1.8 million) was made during the year. Amortisation of $1.0 million (2011: $0.3 million) was charged to the 
Statement of Comprehensive Income during the year.

Employees

The quality and commitment of the Group’s employees has played a major role in the Group’s business success. This has been 
demonstrated in many ways, including strong customer satisfaction, the development of new product offerings and the flexibility 
employees have shown in adapting to changing business requirements. The Group operates sales commission, incentive bonus 
plans and share option and incentive plans to provide incentives for achievements which add value to the business.

Charitable or political donations

No charitable donations were made during the year (2011: $1,600). No political donations were made during the year.

Annual General Meeting

The AGM will be held at the offices of FinnCap Ltd, 60 New Bond Street, London, EC2M 1JJ, on 13 June 2013 at 10.00 a.m.  
The notice convening the meeting is on page 62 together with details of the business to be considered.  

Auditors

In so far as each director is aware:

•    there is no relevant audit information of which the Company’s auditors are unaware; and

•    the directors have taken all the steps that they ought to have taken to make themselves aware of any relevant  

audit information and to establish that the Company’s auditors are aware of that information.

A resolution to re-appoint BDO LLP for the ensuing year will be proposed at the AGM.

As an AIM listed company, Corero is not required to comply with the Corporate Governance Code prepared by the Committee 
on Corporate Governance, appended to the Listing Rules of the FSA, however, the Company has regard to the requirements of 
the Code and its activities in these areas are described below.

The Board

Corero recognises its responsibility to provide entrepreneurial and responsible leadership to the Group within a framework of 
prudent and effective controls (described below) allowing assessment and management of the key issues and risks impacting 
the business. The Board sets Corero’s overall strategic direction, reviews management performance and ensures that the Group 
has the necessary financial and human resources in place to meet its objectives. The Board is satisfied that the necessary 
controls and resources exist within the Group to enable these responsibilities to be met.

Operational management of the Group is delegated to the Executive Director and Business unit heads who meet regularly  
to discuss such matters. These matters include product development and roadmap, sales, customer relationships and 
employee matters.

The Board of Directors comprises the non-executive chairman, one executive director and two non-executive directors whose 
Board and Committee responsibilities as at 31 December 2012 are set out below:

The composition of the Board of Directors is reviewed regularly. Appropriate training, briefings, and induction are available  
to all directors on appointment and subsequently as necessary, taking into account existing qualifications and experience.

Richard Last and Andrew Lloyd are considered to be independent. 

Executive directors’ normal retirement age is 60 and non-executive directors’ normal retirement age is 65. One third of all 
directors are subject to annual reappointment by shareholders as well as any director appointed by the Board in the period  
since the last AGM. Jens Montanana, Andrew Miller and Andrew Lloyd (appointed 19 November 2012) will be offering 
themselves for re-election at the forthcoming AGM.

The Board of Directors meets on average once a quarter and additional meetings are held each year to review and approve the 
Group’s strategy and financial plans for the coming year. Each director is provided with sufficient information to enable them to 
consider matters in good time for meetings and enable them to discharge their duties properly.

All directors have access to the advice and services of the Company Secretary. There is also a procedure in place for any 
director to take independent professional advice if necessary, at the Company’s expense.

The Board also ensures that the principal goal of the Company is to create shareholder value, while having regard to other 
stakeholder interests and takes responsibility for setting the Company’s values and standards.

The Company has an Audit Committee and Remuneration Committee, details of which are set out below.

Audit Committee

The Audit Committee members comprise Richard Last, who is the committee chairman, and Jens Montanana, and meets twice  
a year. The Group Financial Controller, Chief Operating Officer and the Company’s external auditors attend the meetings. The Audit 
Committee considers the adequacy and effectiveness of the risk management and control systems of the Group. It reviews the 
scope and results of the external audit, its cost effectiveness and the objectivity of the auditors. It also reviews, prior to publication, 
the interims, preliminary announcement, the annual financial statements and the other information included in the annual report. 

The Audit Committee met twice in the year ended 31 December 2012. The attendance of individual Committee members at  
Audit Committee meetings in the year to 31 December 2012 is shown in the table below:

The Remuneration Committee met twice times in the year ended 31 December 2012. The attendance of individual Committee 
members at Remuneration Committee meetings in the year to 31 December 2012 is shown in the table below:

–

Due to the size of the Board of Directors, the directors do not consider there to be any need for a nominations committee. Issues 
that would normally be dealt with by a nominations committee are handled by the Board of Directors. The Board of Directors will 
review the need for a nominations committee on a regular basis.

Corero Network Security plcHighlightsBusiness ProfileChairman’s StatementFinancial ReviewGovernanceFinancial StatementsNotice of AGMCorporate Directory 
Corporate Governance Report continued

Internal controls

The directors are responsible for the Group’s system of internal control and for reviewing its effectiveness whilst the role of 
management is to implement policies on risk management and control. The Group’s system of internal control is designed to 
manage, rather than eliminate, the risk of failure to achieve the Group’s business objectives and can only provide reasonable, 
and not absolute, assurance against material misstatement or loss.

The Board continually reviews the effectiveness of other internal controls, including financial, operational, compliance controls 
and risk management. There were no specific reports tabled during the year ended 31 December 2012. 

The Group operates a risk management process, which is embedded in normal management and governance processes. 
As part of the annual strategic planning and budgeting process, each business unit documents the significant risks identified, 
the probability of those risks occurring, their potential impact and the plans for managing and mitigating each of those risks. 

The Group operates a series of controls to meet its needs. These controls include, but are not limited to, the annual strategic 
planning and budgeting process, a clearly defined organisational structure with authorisation limits, reviews by senior 
management of monthly financial and operating information including comparisons with budgets, monthly treasury and cash 
flow reports and forecasts to the Board. 

The Audit Committee receives reports from management and observations from the external auditors concerning the system  
of internal control and any material control weaknesses. Significant risk issues, if any, are referred to the Board of Directors  
for consideration.

The Board of Directors makes an annual assessment of the effectiveness of the Group’s internal control system, including 
financial, operational and compliance controls, before making this statement. The Board of Directors also considers issues 
included in reports received during the year, how the risks have changed during the year and reviews any reports prepared on 
internal controls by management and any issues identified by external auditors. 

The Board of Directors does not believe it is currently appropriate to establish a separate, independent internal audit function 
given the size of the Group.

Remuneration report

The Remuneration Committee’s principal function is to set remuneration of the Group’s executive directors and business unit 
heads to ensure they are fairly compensated. 

Basic salaries are set to ensure high quality executive directors and management are attracted and retained by the Group.  
They reflect the knowledge, skill and experience of each individual director. Bonuses are non-pensionable and only payable  
if the Remuneration Committee assesses the director’s achievements as worthy of the award.

The Remuneration Committee is also responsible for ensuring the Group’s share option schemes are operated properly.  
Details of directors’ share options at 31 December 2012 are disclosed in note 30 of the Financial Statements.

Details of directors’ remuneration for the year ended 31 December 2012 are set out in note 27 of the Financial Statements.  
Jens Montanana has elected to waive the fees payable to him for the financial year ended 31 December 2012.

Andrew Miller, executive director, has a service agreement which is terminable by either party on not less than three  
months’ written notice increasing by one month at the end of each complete 12 month period of continuous employment 
provided that the notice period shall not exceed six months in total. The agreement contains provisions for early termination 
in certain circumstances.

None of the Non-executive Directors has a service agreement. Letters of appointment for Jens Montanana, Richard Last and 
Andrew Lloyd are for 12 month terms and provide that the appointment may be terminated by either party giving to the other  
not less than three months notice. 

22  Corero Network Security plc

Annual Report & Accounts for the year ending 31 December 2012Statement of Directors’ Responsibilities

The directors are responsible for preparing the Annual Report and 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 
elected to prepare the Group and Company financial statements in accordance with International Financial Reporting Standards 
as adopted by the European Union (IFRSs). Under company law the directors must not approve the financial statements unless 
they give a true and fair view of the state of affairs of the Group and parent 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 AIM. In preparing these financial statements, the directors are required to:

•    select suitable accounting policies and then apply them consistently;

•    make judgements and estimates that are reasonable and prudent;

•    state whether applicable IFRSs have been followed, 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 Group will 

continue in business. 

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

The directors are responsible for ensuring the annual report and the financial statements are made available on a website. 
Financial statements are published on the Company’s website in accordance with 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 Company’s website is the responsibility of the directors. The directors’ responsibility also 
extends to the ongoing integrity of the financial statements contained therein.

in our opinion:

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

Amounts prior to 1 January 2012 have been restated as per note 1 to the Financial Statements.

Under the terms of the Top Layer Networks, Inc. acquisition (which has since been renamed Corero Network Security, Inc.), 
deferred consideration of $123,558 payable to the management of Top Layer, was to be satisfied by the issue of 177,145 new 
ordinary shares in the Company to be issued on 2 September 2012 subject to adjustment for set off against any warranty claims 
brought by the Company in accordance with the terms of the acquisition agreement. The Company made a cash payment in 
September 2012 of $105,000 (net of a set-off of $7,500 for warranty claims) to satisfy the deferred consideration obligation. 

The notes on pages 31 to 61 form part of these financial statements. 

30  Corero Network Security plc

Annual Report & Accounts for the year ending 31 December 2012Notes to the Financial Statements

1. General information

Presentation currency

Subsequent to the acquisition and 
integration of the US based Corero 
Network Security division (formerly  
Top Layer Networks) during 2011, the 
Group’s reporting currency has been 
changed to US Dollars (“$”) which is 
more closely aligned to the profile of 
the Group’s revenue and cost base. 
The change is effective from 1 January 
2012 and thus the results for the 12 
months ended 31 December 2012 are 
reported in $. The average $-GBP 
sterling (“GBP”) exchange rate, used 
for the conversion of the statement of 
comprehensive income, for the 12 
months ended 31 December 2012 was 
1.59 (2011: 1.60). The closing $-GBP 
exchange rate, used for the conversion 
of the Group’s assets and liabilities, at 
31 December 2012 was 1.63 (2011: 
1.55, 2010: 1.55). 

Restatement of comparatives

Values in the primary statements and 
notes 5 to 32 relating to the periods 
prior to 1 January 2012 have been 
restated from GBP to $. 

Corero Network Security plc is a public 
limited company incorporated in the 
United Kingdom under the Companies 
Act 2006.

2. Significant accounting policies

2.1 Basis of preparation

The Group and parent Company 
financial statements have been 
prepared in accordance with EU 
endorsed International Financial 
Reporting Standards (IFRS), 
International Financial Reporting 
Interpretations Committee (IFRIC) 
interpretations and those parts of the 
Companies Act 2006 applicable to 
companies reporting under IFRS. 

2.2 Going Concern

The financial statements have been 
prepared on a going concern basis. The 
Group was loss making and used cash 
in operating activities during the year.

Where necessary, adjustments are 
made to the financial statements of 
subsidiaries to bring the accounting 
policies used into line with those used 
by the Group.

The directors have prepared detailed 
income statement, balance sheet and 
cash flow projections for the period to 
31 December 2014. The cash flow 
projections have been subjected to 
sensitivity analysis at the revenue, cost 
and combined revenue and cost levels. 
The cash flow projections show that 
the Group will maintain a positive cash 
balance until at least 31 December 
2014 on the assumption that the 8% 
Loan Notes (see note 20) which are 
due for repayment in March 2014 will  
be refinanced.

As a result, the directors are of the 
opinion that the Group has adequate 
working capital to continue as a going 
concern for the foreseeable future and, 
in particular, for a period of at least 12 
months from the date of approval of 
these financial statements. 

2.3 Basis of consolidation

The consolidated financial statements 
incorporate the results, assets, liabilities 
and cash flows of the Company and 
each of its subsidiaries for the financial 
year ended 31 December 2012. 

Subsidiaries are entities controlled by 
the Group. Control is deemed to exist 
when the Group has the power, directly 
or indirectly, to govern the financial and 
operating policies of an entity so as to 
obtain benefits from its activities. The 
results, assets, liabilities and cash flows 
of subsidiaries are included in the 
consolidated financial statements from 
the date control commences until the 
date that control ceases.

The merger reserve which was 
transferred to retained earnings in  
the prior year related to a realised 
investment in a former division of  
a subsidiary undertaking.

Intra-group balances and transactions 
are eliminated on consolidation.

2.4 Business combinations

The acquisition method is used to 
account for all acquisitions. The cost  
of an acquisition is measured at the  
fair values, on the date of exchange,  
of assets given, liabilities incurred or 
assumed, and equity instruments issued. 

At the date of acquisition, the identifiable 
assets and liabilities and contingent 
liabilities of a subsidiary are measured at 
their fair values. Any excess of the cost 
of acquisition over the fair values of the 
identifiable net assets acquired is 
recognised as goodwill.

Non-controlling interests are initially 
recognized at their fair value. The total 
comprehensive income of non-wholly 
owned subsidiaries is attributed to 
owners of the parent and to the 
non-controlling interests in proportion 
to their relative ownership interests.

2.5 Revenue

Revenue is measured at the fair value of 
the consideration received or receivable 
and represents the amounts receivable 
for services provided in the normal 
course of business, net of all related 
discounts and sales tax.

Annual Report & Accounts for the year ending 31 December 2012  31

Corero Network Security plcHighlightsBusiness ProfileChairman’s StatementFinancial ReviewGovernanceFinancial StatementsNotice of AGMCorporate Directory 
The Group has adopted the following 
policy in respect of revenue recognition:

1. Software Products
Revenue results mainly from the sale  
of licences, which provide customers 
with the right to use these products. 
Such revenue is recognised on the 
following basis:

i.   If an arrangement to deliver  

software or a software system,  
either alone or together with other 
products or services, requires 
significant production, modification, 
or customisation, the revenue for 
both services and software is 
recognised under the percentage  
of completion method.

ii.  If services are essential to the 

functionality of the software and the 
payment terms are linked, the revenue 
for both software and services is 
recognised when the following 
conditions are met:

  – A signed contract exists;

  – Delivery has occurred;

  –  The sales price is fixed  
and determinable;

  – Collection of the debt is probable;

  – No significant obligations remain.

iii.  If services are incidental to the 

functionality and/or the payment 
terms are linked to installations, 
revenue from the grant of perpetual  
or fixed term licences to use Corero’s 
software products revenue is 
recognised when the above 
conditions are met and services 
revenue is recognised separately as 
the services are provided. Where 
services are not incidental to the 
functionality, licence revenues are 
recorded as agreed project 
milestones are achieved.

2. Hardware and Software Products
When a sales arrangement contains 
multiple elements, such as hardware  
and software products, licenses and/or 
services, the Group allocates revenue  
to each element based on a selling  
price hierarchy, having evaluated each 
deliverable in an arrangement to 
determine whether they represent 
separate units of accounting. A 
deliverable constitutes a separate unit of 
accounting when it has standalone value.

The selling price for a deliverable is 
based on its vendor specific objective 
evidence (“VSOE”) if available, third 
party evidence (“TPE”) if VSOE is not 
available, or best estimated selling price 
(“BESP”) if neither VSOE nor TPE is 
available. In multiple element 
arrangements where more-than-
incidental software deliverables are 
included, revenue is allocated to each 
separate unit, accounting for each of 
the non-software deliverables and to 
the software deliverables as a group 
using the relative selling prices of each 
of the deliverables in the arrangement 
based on the aforementioned selling 
price hierarchy.

The Group establishes the VSOE of 
selling price using the price charged for 
a deliverable when sold separately. The 
TPE of selling price is established by 
evaluating similar and interchangeable 
competitor products or services in 
standalone sales to similarly situated 
customers. The best estimate of selling 
price is established considering both 
internal and external factors such as 
pricing practices, customer pricing 
strategies, margin objectives, market 
conditions, competitor pricing strategies, 
and industry technology lifecycles.

3. Consulting and Professional Services
Revenue from the provision of 
consultancy and professional services 
is recognised as the work is performed.

4. Support income
Support income is recognised on  
a straight line basis over the life of  
the agreement.

2.6 Cost of sales

Cost of sales includes all direct costs 
associated with revenue generation, 
including services delivery, support 
costs and amounts charged by external 
third parties for services and goods 
directly related to revenue. Examples  
of such costs would include, but not be 
limited to, external consultants and third 
party hardware and software costs. 

2.7 Foreign currencies

Transactions in foreign currencies are 
translated at the exchange rate ruling at 
the date of each transaction. Foreign 
currency monetary assets and liabilities 
are retranslated using the exchange 
rates at the reporting date. Gains and 
losses arising from changes in exchange 
rates after the date of the transaction are 
recognised in profit or loss in the 
Statement of Comprehensive Income. 

Non-monetary assets and liabilities that 
are measured in terms of historical cost 
in a foreign currency are translated at 
the exchange rate at the date of the 
original transaction.

In the consolidated financial 
statements, the net assets of the 
Group’s UK operations are translated 
at the exchange rate at the reporting 
date. Income and expense items are 
translated at the average exchange 
rates for the period. The resulting 
exchange differences are recognised  
in the translation reserve. Such 
translation differences are recognised 
in profit or loss on the disposal  
of the UK operation.

Annual Report & Accounts for the year ending 31 December 2012Notes to the Financial Statements continued2.8 Intangible assets

Internally generated intangible assets
The Group’s internally generated 
intangible asset relates to its 
development expenditure.

Development expenditure is capitalised 
only when it is probable that future 
economic benefit will result from the 
project and the following criteria are met:

•    The technical feasibility of the 
product has been ascertained;

•    Adequate, technical, financial and 
other resources are available to 
complete and sell or use the 
intangible asset;

•    The Group can demonstrate how the 

intangible asset will generate future 
economic benefits and the ability to 
use or sell the intangible asset can 
be demonstrated;

•    It is the intention of management to 
complete the intangible asset and 
use it or sell it; and 

•    The development costs can be 

measured reliably.

Expenditure not meeting these  
criteria is expensed in the Statement  
of Comprehensive Income.

After initial recognition, internally 
generated intangible assets are carried 
at cost less accumulated amortisation 
and any impairment losses.

Acquired intangible assets
Purchased computer software is carried 
at cost less accumulated amortisation 
and any impairment losses.

Customer contracts and the related 
customer relationships are carried at 
cost less accumulated amortisation  
and any impairment losses.

Identifiable intangible assets acquired 
as part of a business combination are 
initially recognised separately from 
goodwill, irrespective of whether the 
assets have been recognised by the 
acquiree before the business 
combination. An intangible asset is 
considered identifiable only if it is 
separable or if it arises from contractual 
or other legal rights, regardless of 
whether those rights are transferable or 
separable from the entity or from other 
rights and obligations.

Intangible assets acquired as part of a 
business combination and recognised 
by the Group are computer software, 
customer contracts and the related 
customer relationships.

After initial recognition, assets acquired 
as part of a business combination are 
carried at cost less accumulated 
amortisation and any impairment losses.

Amortisation
Intangible assets are amortised on a 
straight line basis, to reduce their 
carrying value to zero over their 
estimated useful lives. The following 
useful lives were applied during the year:

•    Computer software acquired –  

3 or 5 years straight line

•    Customer contracts and the  

related customer relationships – 
7 years straight line

•    Capitalised development 

expenditure – 5 years straight line

Amortisation costs are included within 
operating expenses in the Statement  
of Comprehensive Income.

Methods of amortisation and useful 
lives are reviewed, and if necessary 
adjusted, at each reporting date.

2.9 Property, plant and equipment

Property, plant and equipment is stated 
at cost less accumulated depreciation 
and any impairment losses. Cost 
comprises the purchase cost of 
property, plant and equipment together 
with any directly attributable costs.

Subsequent costs are included in an 
asset’s carrying value or are recognised 
as a separate asset when it is probable 
that future economic benefits 
associated with the additional 
expenditure will flow to the Group and 
the cost of the item can be measured 
reliably. All other costs are charged to 
the Statement of Comprehensive 
Income as incurred.

Depreciation commences when an 
asset is available for use. Depreciation 
is calculated so as to write off the cost 
or value of an asset, net of anticipated 
disposal proceeds, over the useful life 
of that asset as follows:

•    Leasehold improvements – 

Period of the lease straight line

•    Computer equipment – 
2 to 4 years straight line

•    Fixtures and fittings – 

2 to 5 years straight line

•    Office equipment – 

3 to 5 years straight line

Methods of depreciation, residual 
values and useful lives are reviewed, 
and if necessary adjusted, at each 
balance sheet date.

The gain or loss arising from the 
disposal or retirement of an item of 
property, plant and equipment is 
determined as the difference between 
the net disposal proceeds and the 
carrying amount of the item, and is 
included in the Statement of 
Comprehensive Income.

Corero Network Security plcHighlightsBusiness ProfileChairman’s StatementFinancial ReviewGovernanceFinancial StatementsNotice of AGMCorporate Directory 
2.10 Inventory

Inventory is stated at the lower of  
cost or net realisable value. Cost is 
computed using standard cost, which 
approximates actual cost, on a first-in, 
first-out basis. Rapid technological 
change and new product introductions 
and enhancements could result in 
excess or obsolete inventory. To 
minimise this risk, the Group evaluates 
inventory levels and expected usage on 
a periodic basis and records valuation 
allowances as required.

2.11 Impairment

At each reporting date, the Group 
assesses whether there is any 
indication that its assets have been 
impaired. If any such indication exists, 
the recoverable amount of the asset is 
estimated in order to determine the 
extent of any impairment. If it is not 
possible to estimate the recoverable 
amount of the individual asset, the 
recoverable amount of the cash-
generating unit to which the asset 
belongs is determined.

The recoverable amount of an asset or a 
cash-generating unit is the higher of its 
fair value less costs to sell and its value 
in use. The value in use is the present 
value of the future cash flows expected 
to be derived from an asset or cash-
generating unit. This present value is 
discounted using a pre-tax rate that 
reflects current market assessments of 
the time value of money and of the risks 
specific to the asset for which future 
cash flow estimates have not been 
adjusted. If the recoverable amount of 
an asset is less than its carrying 
amount, the carrying amount of the 
asset is reduced to its recoverable 
amount. That reduction is recognised  
as an impairment loss.

An impairment loss relating to assets 
carried at cost less any accumulated 
depreciation or amortisation is 
recognised immediately in the 
Statement of Comprehensive Income.

Goodwill acquired in a business 
combination is, from the acquisition 
date, allocated to each of the cash-
generating units or groups of cash-
generating units that are expected  
to benefit from the synergies of  
the combination.

Goodwill is tested for impairment at 
least annually, and whenever there  
is an indication that the asset may  
be impaired.

An impairment loss is recognised for 
cash-generating units if the recoverable 
amount of the unit is less than the 
carrying amount of the unit. The 
impairment loss is allocated to reduce 
the carrying amount of the assets of the 
unit by first reducing the carrying 
amount of any goodwill allocated to the 
cash-generating unit, and then reducing 
the carrying amounts of the other 
assets of the unit pro rata.

If an impairment loss subsequently 
reverses, the carrying amount of the asset 
is increased to the revised estimate of its 
recoverable amount but limited to the 
carrying amount that would have been 
determined had no impairment loss been 
recognised in prior years. A reversal of an 
impairment loss is recognised in the 
Statement of Comprehensive Income. 
Impairment losses on goodwill are not 
subsequently reversed.

2.12 Borrowing costs

All borrowing costs directly attributable 
to a qualifying asset are capitalised as 
part of the cost of the asset. 

2.13 Leases

Where substantially all of the risks and 
rewards incidental to ownership of a 
leased asset are transferred to the 
Company (a “finance lease”), the asset 
is treated as if it had been purchased 
outright. The amount initially recognised 
as an asset is the lower of the fair value 
of the leased property and the present 
value of the minimum lease payments 
payable over the term of the lease. The 
corresponding lease commitment is 
shown as a liability. Lease payments are 
analysed between capital and interest. 
The interest element is charged to the 
Statement of Comprehensive Income 
over the period of the lease and is 
calculated so that it represents a 
constant proportion of the lease liability. 
The capital element reduces the 
balance owed to the lessor.

Where substantially all of the risks and 
rewards incidental to ownership are not 
transferred to the Company (an 
“operating lease”), the total rentals 
payable under the lease are charged to 
the Statement of Comprehensive 
Income on a straight-line basis over the 
lease term. The aggregate benefit of 
lease incentives is recognised as a 
reduction of the rental expense over  
the lease term on a straight-line basis.

2.14 Investments in subsidiaries

In the Company’s separate financial 
statements, investments in  
subsidiaries are carried at cost  
less any impairment provisions.

2.15 Taxation

The tax expense represents the sum  
of current tax and deferred tax.

34  Corero Network Security plc

Annual Report & Accounts for the year ending 31 December 2012Notes to the Financial Statements continuedCurrent tax
Current tax is based on taxable profit 
for the year and is calculated using tax 
rates enacted or substantively enacted 
at the reporting date. Taxable profit 
differs from accounting profit either 
because items are taxable or deductible 
in periods different to those in which 
they are recognised in the financial 
statements, or because they are never 
taxable or deductible.

Deferred tax
Deferred tax on temporary differences 
at the reporting date between the tax 
bases of assets and liabilities and their 
carrying amounts for financial reporting 
purposes is accounted for using the 
balance sheet liability method.

Using the balance sheet liability 
method, deferred tax liabilities are 
recognised in full for all taxable 
temporary differences and deferred  
tax assets are recognised to the extent 
that it is probable that taxable profits 
will be available against which 
deductible temporary differences can 
be utilised. However, if the temporary 
difference arises from the initial 
recognition of goodwill or the initial 
recognition of an asset or liability in a 
transaction other than a business 
combination, that at the time of the 
transaction affects neither accounting 
nor taxable profit, it is not recognised 
as deferred tax asset or liability.

Deferred taxation is measured at the 
tax rates that are expected to apply 
when the asset is realised, or the 
liability settled, based on tax rates and 
laws enacted or substantively enacted 
at the reporting date.

2.16 Provisions

A provision is recognised when, as a 
result of a past event, the Group has a 
legal or constructive obligation, it is 
probable that an outflow of resources 
embodying economic benefits will be 

required to settle the obligation and a 
reliable estimate of the amount of such 
an obligation can be made.

Provisions are measured at the best 
estimate of the expenditure required to 
settle the obligation at the reporting date. 
When the effect is material, the expected 
future cash flows required to settle the 
obligation are discounted at the pre-tax 
rate that reflects the current market 
assessments of the time value of money 
and the risks specific to the obligation.

2.17 Post-retirement benefits

The Group operates defined 
contribution group personal pension 
plans under which it is required to pay 
fixed contributions to separate funds 
controlled by trustees. Contributions to 
the schemes are based on a proportion 
of the employees’ earnings and are 
charged to the Statement of 
Comprehensive Income when incurred. 
The Group has no obligation to the 
scheme beyond these contributions.

2.18 Financial instruments

The Group classifies financial 
instruments, or their component  
parts, on initial recognition as a  
financial asset, a financial liability or  
an equity instrument in accordance  
with the substance of the  
contractual arrangement.

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

The particular recognition and 
measurement methods adopted for  
the Group’s financial instruments are 
disclosed below:

Trade and other receivables
Trade and other receivables are stated 
at their fair value at time of initial 
recognition, reflecting where material 
the time value of money. A provision for 

impairment of trade receivables is 
established when there is evidence that 
the Group will not be able to collect all 
amounts due according to the original 
terms of these receivables. The amount 
of the provision is the difference 
between the carrying value and the 
present value of estimated future cash 
flows, discounted at the original 
effective interest rate. 

Cash and cash equivalents
Cash and cash equivalents include cash 
in hand, deposits on call with banks and 
bank overdrafts. Bank overdrafts are 
disclosed as current borrowings in the 
statement of financial position.

Trade and other payables
Trade and other payables are not 
interest bearing and are stated at their 
fair value at time of initial recognition. 
Thereafter they are accounted for at 
amortised cost.

2.19 Equity instruments

An equity instrument is any contract 
that evidences a residual interest in the 
assets of the Company after deducting 
all its liabilities. Equity instruments 
issued by the Company are recorded  
at the proceeds received, net of  
directly attributable issue cost.

2.20 Employee share option schemes

The Group operates an equity-settled 
share-based compensation plan. The 
fair value of the employees’ services 
received in exchange for the grant of 
share options is measured at grant date 
and recognised as an expense on a 
straight line basis over the vesting 
period, based on the Group’s estimate 
of shares that will eventually vest. Fair 
value is determined by reference to the 
Black Scholes option pricing model.

At each reporting date, the Group revises 
its estimate of the number of options that 
are expected to become exercisable.

Annual Report & Accounts for the year ending 31 December 2012  35

Corero Network Security plcHighlightsBusiness ProfileChairman’s StatementFinancial ReviewGovernanceFinancial StatementsNotice of AGMCorporate Directory 
When share options are exercised,  
the proceeds received, net of any 
transaction costs, are credited to  
share capital (nominal value) and  
share premium.

2.21 Invoice discounting

The group makes use of an invoice 
discounting facility to fund certain of 
its operations. Trade receivables are 
recognised as the Group retains the 
significant risks and benefits. The 
related funding is shown as a financial 
liability and accounted for on an 
amortised cost basis.

2.22 Standards and Interpretations 
not yet effective

The standards and interpretations that 
are issued but not yet effective at the 
date of authorisation of these financial 
statements are those that the Group 
reasonably expects will have an impact 
on disclosures, financial position or 
performance when applied at a future 
date. The Group intends to adopt these 
standards and interpretations, if 
applicable, when they become effective.

IAS 1 Presentation of Items of  
Other Comprehensive Income – 
Amendments to IAS 1

The amendments to IAS 1 change the 
grouping of items presented in other 
comprehensive income (OCI). Items 
that could be reclassified (or recycled) 
to profit or loss at a future point in  
time would be presented separately 
from items that will never be 
reclassified. The amendment affects 
presentation only and therefore has  
no impact on the Group’s financial 
position or performance.

The amendments to IAS 1 are effective 
for annual periods beginning on or after 
1 July 2012.

IFRS 10 Consolidated  
Financial Statements

IFRS 10 establishes a single control 
model that applies to all entities including 
structured entities (previously referred to 
as special purpose entities). The 
changes introduced by IFRS 10 will 

36  Corero Network Security plc

require management to exercise 
significant judgement to determine which 
entities are controlled and therefore are 
required to be consolidated by a parent, 
compared with the requirements that 
were in IAS 27. IFRS 10 is not expected 
to have any impact on the investments 
currently held within the Group.

This standard is effective for annual 
periods beginning on or after 
1 January 2013.

IFRS 12 Disclosure of Interests  
in Other Entities

These disclosures relate to an  
entity’s interests in subsidiaries,  
joint arrangements, associates and 
structured entities. A number of new 
disclosures are also required, but will 
have no impact on the Group’s financial 
position or performance.

This standard is effective for annual 
periods beginning on or after  
1 January 2013.

3. Critical accounting  
judgements and key sources  
of estimation uncertainty

3.1 Critical judgements in applying 
the Group’s accounting policies

In the process of applying the Group 
accounting policies, the following 
judgements have had a significant  
effect on the amounts recognised in 
the financial statements:

Internally generated research  
and development costs
Management monitors progress of 
internal research and development 
projects. Judgement is required in 
distinguishing the research phase from 
the development phase. Development 
costs are recognised as an asset when 
all criteria are met, whereas research 
costs are expensed as incurred. 
Management monitors whether  
the recognition requirements for 
development costs continue to be  
met. This is necessary as the  
economic success of any product 
development is uncertain.

3.2 Key accounting estimates  
and assumptions

Key assumptions concerning the future 
and other key sources of estimation 
uncertainty that have a significant risk  
of causing a material adjustment to  
the carrying amounts of assets and 
liabilities within the next financial year, 
are as follows:

Impairment of intangible assets  
and property, plant and equipment
The Group tests goodwill at least 
annually for impairment, and whenever 
there is an indication that the asset may 
be impaired. All other intangible assets 
and property, plant and equipment are 
tested for impairment when indicators 
of impairment exist. Impairment is 
determined with reference to the higher 
of fair value less costs to sell and value 
in use. Value in use is estimated using 
discounted future cash flows. 
Significant assumptions are made in 
estimating future cash flows about 
future events including future market 
conditions, future growth rates and 
apporpriate discount rates. Changes in 
these assumptions could affect the 
outcome of impairment reviews. 
Changes in these assumptions could 
affect the outcome of impairment 
reviews. Details of the main assumptions  
used in the assessment of the carrying 
value of the Group’s cash generating 
units are set out in note 12.

Impairment of investments and 
intercompany balances (applies to the 
Company Financial Statements only)

The directors have reviewed the carrying 
value of the intercompany balances and 
cost of investments in subsidiaries of the 
Company with reference to current and 
future trading conditions. The investment 
and intercompany balance between the 
Company and Corero Business Systems 
Limited has been reviewed by reference 
to a valuation based on a multiple of the 
2012 profit which the directors consider 
to be an appropriate valuation method.

The investment and intercompany 
balances between the Company and 
Corero Network Security, Inc. and 

Annual Report & Accounts for the year ending 31 December 2012Notes to the Financial Statements continuedCorero Network Security (UK) Limited 
have been reviewed with reference to 
a valuation based on a discounted free 
cash flow which the directors consider 
to be an appropriate valuation 
methodology, in conjunction with  
the goodwill impairment review. 

Going Concern
The directors have reviewed the future 
profit and cash flow projections in 
conjunction with the current economic 
climate in order to express an opinion  
on the adequacy of working capital  
and the ability to continue as a going  
concern for the foreseeable future.  
The methodology and uncertainties 
contained in the projections are  
detailed in the note 2.2. 

4. Financial risk management

Capital management

The Group monitors its available capital, 
which it considers to be all components 
of equity other than amounts reflecting 
non-controlling interests, against its 
expected requirements. 

The Group’s objectives when maintaining 
capital are to safeguard the entity’s 
ability to continue as a going concern, so 
that it can continue to provide returns for 
shareholders and benefits for other 
stakeholders, and to ensure that 
sufficient funds can be raised for 
investing activities. In order to maintain 
or adjust the capital structure, the Group 
may return capital to shareholders, issue 
new shares, or sell assets to reduce 
debt. The Group does not review its 
capital requirements according to any 
specified targets or ratios.

Treasury management

Group treasury policies are reviewed and 
approved by the Board. The objectives of 
Group treasury policies are to ensure that 
adequate financial resources are available 
for development of the business while at 
the same time managing financial risks. 
Financial instruments are used to reduce 
financial risk exposures arising from the 
Group’s business activities and not for 
speculative purposes.

The Group’s treasury activities are 
managed by the Group finance function 
under the direction of the Group 
Financial Controller. The Group Financial 
Controller reports to the Board on the 
implementation of Group treasury policy.

The Group’s business activities  
expose it to a variety of financial risks. 
The policies for managing these risks 
are described below:

Liquidity risk
Liquidity risk is the risk that arises from 
the Group’s management of working 
capital and finance charges. It is the risk 
that the Group will encounter difficulty 
in meetings its financial obligations as 
they fall due. Liquidity risk is managed 
centrally by the finance function. 
Budgets are set locally and centrally, 
and agreed by the Board annually in 
advance, enabling the Group’s cash 
flow requirements to be anticipated. 

Credit risk
Credit risk arises from cash and cash 
equivalents and from credit exposures 
to the Group’s customers including 
outstanding receivables and committed 
transactions. Credit risk is managed with 
regular reports of exposures reviewed by 
management. The Group does not set 
individual credit limits but will seek to 
ensure that customers enter into legally 
enforceable contracts that include 
settlement terms that demonstrate the 
customers’ commitment to the transaction 
and minimise this risk exposure.

The amounts of trade receivables 
presented in the Statement of Financial 
Position are shown net of allowances  
for doubtful accounts estimated by 
management based on prior experience 
and their assessment of the current 
economic environment (note 18).

The credit risk on liquid funds and 
financial instruments is limited because 
the counterparties are banks with 
acceptable credit ratings assigned by 
international credit rating agencies.

The Group has no significant 
concentration of credit risk, with 
exposure spread over a large number  
of customers.

Cash flow interest rate risk
The Group’s policy is to minimise 
interest rate cash flow risk exposure on 
its financing. The majority of the Group’s 
financing is held in fixed rate loans 
therefore no analysis of interest rate 
sensitivity is presented. 

The Group’s policy is to balance the risk 
in relation to cash balances held by 
spreading these across a number of 
financial institutions as opposed to 
maximising interest income. 

Currency risk
There is no material impact on the 
Group’s Statement of Comprehensive 
Income from exchange rate movements, 
as foreign currency transactions are 
entered into by Group companies whose 
functional currency is aligned with the 
currencies in which it transacts.

5. Segment reporting

Business segments

The Group is managed according to two 
business units which make up the 
Group’s two reportable operating 
segments: Corero Network Security and 
Corero Business Systems. These 
divisions are the basis on which the 
Group reports its primary segment 
information to the Board, which 
management consider to be the Chief 
Operating Decision maker for the 
purposes of IFRS 8 Operating 
Segments. The principal activity of 
Corero Network Security is the design, 
development and delivery of network 
security products. The principal activity 
of Corero Business Systems is the 
design, development and delivery of 
finance and management information 
software to the school, further 
education and commercial sectors.

Central costs comprise mainly central 
and parent company overheads relating 
to the group management, the finance 
function and regulatory requirements.

As at 31 December 2012, the Group’s cumulative fixed asset timing differences were $24,000 (2011: $86,000) and no deferred 
tax asset has been recognised in respect of these items.

In addition, the tax losses at that date amounted to $37.7 million (2011: $31.4 million). This comprised UK tax losses of $10.0 
million and US tax losses of $27.7 million. $4.2 million of the tax losses relate to US capitalised R&D deductions which will be 
available at an accelerated level for 4 years. $9.0 million of the tax losses relate to pre-acquisition US tax losses which can be 
offset against taxable profits over 19 years (there is a limit on the utilisation of pre-acquisition tax losses of $0.7 million per 
annum and any unused loss may be carried forward to subsequent periods). All other US tax losses will expire in 20 years from 
the end of the accounting period in which the loss arose. 

The deferred tax asset at a rate 23% of $1.9 million (2011: $1.9 million) relating to the UK tax losses (after offsetting the deferred 
tax liability of $0.4 million (2011: $0.3 million) relating to capitalised research and development expenditure) and the deferred tax 
asset at a rate of 35% of $9.7 million (2011: $7.7 million) relating to the US tax losses have not been recognised due to 
uncertainties as to the extent and timing of their future recovery.

10. Profit of the parent Company for the financial year

The Company has taken advantage of section 408 of the Companies Act 2006 and has not included an income statement  
in these financial statements. The parent Company’s profit for the year was $430,000 (2011: $6,831,000).

11. Loss per share

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

At the reporting dates there were no potentially dilutive ordinary shares. Therefore the diluted loss per share is equal to the loss per share.

Goodwill is tested at least annually for impairment and whenever there are indications that goodwill might be impaired.

Goodwill is allocated to the Group’s cash-generating units (CGUs) which are the Corero Network Security (“CNS”) division  
and Resource EMS (“REMS”), part of the Corero Business Systems division. 

As at 31 December the carrying amount of goodwill allocated to each of these CGUs is:

The recoverable amount for the CNS CGU was determined based on a value-in-use calculation using cash flow projections over 
a 10 year period (2011: 5 year period). The key assumptions for the value-in-use calculation are those regarding revenue growth 
and discount rates as summarised in the table below and commented on below. 

Forecast cash flow period

Extrapolated cash flow period

Cumulative annual growth rate (CAGR) for revenue used for the forecast/extrapolated period 

Revenue growth rates used beyond the extrapolated period

Discount rate

Corero Network Security plcHighlightsBusiness ProfileChairman’s StatementFinancial ReviewGovernanceFinancial StatementsNotice of AGMCorporate Directory 
•    The pre-tax cash flows for the forecast period are derived from the most recent financial budget for the year ending  
31 December 2013 and the plan for the year ending 31 December 2014 approved by the Board. The extrapolation for  
the period 2015 to 2022 is based on management estimates (with the key assumptions set out below).

•    The future pre-tax cash flows are discounted by a weighted average cost of capital (“WACC”) of 11.2% for the period in 

which CNS utilises tax losses carried forward to reduce tax payable to nil and a WACC of 15.6% thereafter once the cost  
of tax becomes relevant.

•    The key assumptions underlying the cash flow projections and which the recoverable amount is most sensitive to are (i)  

the revenue growth rates forecast and extrapolated for the period 2013 to 2017 (ii) and the discount rate. 

i. 

 The cash flow forecasts assume a CAGR revenue growth of 25.5% in the period 2013 to 2017 (43.3% for the period 
2013 to 2014) and 4.0% for the period 2018 to 2022 (a CAGR of 14.3% for 10 year forecast period). The management  
of the Group believe these growth rates are appropriate for the forecasts following CNS’ repositioning as a First Line of 
Defense in 2012, management changes, investment in product development (and the next generation product which is 
expected to be available by the end of 2013 which is expected to deliver a step change in revenue in 2014), channel 
partner enablement and marketing.

 These growth rates are supported by the fact that the IT security market is forecast to grow strongly for the foreseeable 
future. Gartner for instance forecast that the IT security market will grow by a CAGR of 8.9% in the period 2011 to 2016 
and Infonetics forecast that the DDoS protection market will grow from $270 million in 2012 to $485 million in 2016 
(CAGR 16%). 

 The above market growth rates used in the future cash flow assumptions reflect that CNS is in the early stages of the 
commercial exploitation of its intellectual property. In addition, the business’ strategy is to continue to develop its 
product and solution offerings to remain a market leader in its chosen markets thereby providing the opportunity to 
generate above market average growth rates.

 The growth rate assumed in the period beyond the 10 year extrapolation period of 1.5% is considered reasonable  
as historically IT spend has exceeded GDP growth.

ii. 

 The discount rate is based on a cost of equity using the Capital Asset Pricing Model with the key inputs being a 
risk-free interest rate estimate of 2.95% (based on 30 year US government bonds), comparable company betas, an 
equity risk premium of 5% and small company risk premium of 4.5%. The WACC has been assessed based on a long 
term cost of debt of 6.5% and a gearing level based on the Company gearing at 31 December 2012. The WACC used in 
the valuation reflects current market assessments of the time value of money and the risks specific to CNS.

As stated above, the valuation to support the value in use of the CNS CGU is highly sensitive to negligible changes in cash flow 
forecasts and discount rate assumptions, and there is no guarantee that the expected growth will be achieved. If the expected 
growth is not achieved, this could result in a requirement to impair the goodwill associated with the CNS CGU in the future. If the 
revenue growth in 2013 and 2014 is reduced by 10% (which in the assessment of management is reasonably possible) in 2013 
and 2014, and the same reduction is made to overheads, this would result in an impairment of goodwill associated with the CNS 
CGU of $2.8 million. If the discount rate is increased by 10% (which in the assessment of management is reasonably possible), 
this would result in an impairment of goodwill associated with the CNS CGU of $4.5 million.

Apart from the considerations in determining the value in use of the CNS CGU described above, the management of the Group 
is not currently aware of any other reasonably possible changes that would necessitate changes in its key estimates.

The recoverable amount for the REMS CGU unit was determined based on a value-in-use calculation using cash flow 
projections over a five year period which is considered an appropriate period given the REMS business is a mature business 
with a demonstrable track record. The key assumptions for the value-in-use calculation are summarised in the table below:

Forecast cash flow period

Extrapolated cash flow period

CAGR for revenue used in the forecast/extrapolated period

The accounts receivable financing facility bears interest at c.8% of the financed value. The facility limit is US$1.5 million. 80%  
of the eligible accounts receivable balance can be financed. The facility requires a minimum quick asset ratio covenant of 1.15:1.

The term loan comprises two term loans of $250,000 each which bear interest at 8.5% and are repayable over 33 months. The 
first term loan matures in October 2014. The second term loan matures in April 2015. 

Interest on the 8% Loan Notes principal ($5.0 million) is at the election of Corero Network Security, Inc. payable bi-annually or 
added to the principal amount. Corero Network Security, Inc. has elected to add the interest to the principal. Rolled up interest 
at 31 December 2012 amounted to $0.8m. The Loan Notes are repayable on 2 March 2014.

Undrawn facilities at 31 December 2012 amounted to $813,000 comprising the Corero Business Systems Limited overdraft 
facility. The facility, if drawn, requires 150% trade receivables cover and is secured over the assets of Corero Business Systems 
Limited. In addition, the Company has provided a guarantee. 

At 31 December 2012, the Group’s liabilities have contractual maturities which are summarised below. These contractual

The Group and Company do not have any contingent liabilities (2011: $nil).

On 17 March 2011, the Corero Remuneration Committee approved the establishment of the Corero Early Exit Incentive Plan 
(“EEIP”). The EEIP is a cash settled change of control incentive plan for the senior executives of the Group that provides for a 
cash payment in the event of (i) a sale of substantially all of the assets of the Corero Network Security business, or (ii) an offer 
for all of the shares of Corero Network Security plc, in the period up to 30 April 2014 (thereafter it will lapse). 

The cash incentive payment is determined based on the difference between (i) the value of the transaction (consideration for the 
sale of all or substantially all of the assets of Corero Network Security, Inc. or offer for all of Corero Network Security plc’s 
shares) and (ii) Corero Network Security plc’s accumulated cost of capital comprising the cash investment by Corero Network 
Security plc shareholders and shares issued for acquisitions or other purposes, defined as the “Total Gain”. The EEIP will pay 
those executives granted the incentive a percentage of the Total Gain. Under the terms of the EEIP, awards up to a maximum of 
3.0% of the Total Gain can be issued with a maximum of 0.5% per individual. At 31 December 2012, EEIP awards comprising 
1.7% of the Total Gain had been awarded (including an award of 0.5% to Andrew Miller, a Company director).

As at the date of this report no discussions are in progress or contemplated which would result in the incentive payment being 
payable. As a result no provision has been recorded in the financial statements relating to the EEIP.

30. Share options

The Company has the following share option schemes:

•    Enterprise Management Incentive Scheme for its employees, which has been approved by HMR&C 

•    2010 Executive Enterprise Management Incentive Scheme, which has been approved by HMR&C 

•    2010 Unapproved Share Option Scheme

•    Deferred Payment Share Plan

In August 2010, 1,257,000 options were granted to certain directors and employees under the 2010 Executive Enterprise 
Management Incentive scheme and 2010 Unapproved Share Option Scheme. The options granted vested immediately upon grant.

All other options granted in 2010-2012 have a three year vesting period, vesting one third on the first anniversary of grant, one 
third on the second anniversary of grant and one third on the third anniversary of grant. There are no vesting conditions.

Notice of AGM continued

Notes:

1.   Pursuant to Regulation 41 of the Uncertificated Securities 
Regulations 2001 (as amended), only those members 
registered in the register of members of the Company at 6.00 
p.m. on 11 June 2013 (or if the AGM is adjourned, on the day 
which is two business days before the time fixed for the 
adjourned AGM) shall be entitled to attend and vote at the 
AGM in respect of the number of shares registered in their 
name at that time. Any changes to the register of members 
after such time shall be disregarded in determining the rights 
of any person to attend or vote at the AGM.

2.   CREST members who wish to appoint a proxy or proxies 

through the CREST electronic proxy appointment service may 
do so for the AGM to be held at 10.00 a.m. on 13 June 2013 
and any adjournment(s) thereof by using the procedures 
described in the CREST Manual. CREST personal members 
or other CREST sponsored members, and those CREST 
members who have appointed a voting service provider 
should refer to their CREST sponsors or voting service 
provider(s), who will be able to take the appropriate action on 
their behalf.

In order for a proxy appointment or instruction made by 
means of CREST to be valid, the appropriate CREST message 
(a “CREST Proxy Instruction”) must be properly authenticated 
in accordance with Euroclear UK & Ireland Limited’s 
specifications and must contain the information required for 
such instructions, as described in the CREST Manual. The 
message must be transmitted so as to be received by the 
Company’s agent, Capita Registrars Limited (CREST 
Participant ID: RA1 0), no later than 10. 00 a.m. on 11 June 
2013. For this purpose, the time of receipt will be taken to be 
the time (as determined by the time stamp applied to the 
message by the CREST Application Host) from which the 
Company’s agent is able to retrieve the message by enquiry 
to CREST in the manner prescribed by CREST.

CREST members and, where applicable, their CREST sponsor 
or voting service provider should note that Euroclear UK & 
Ireland Limited does not make available special procedures in 
CREST for any particular messages. Normal system timings 
and limitations will therefore apply in relation to the input of 
CREST Proxy Instructions. It is the responsibility of the 
CREST member concerned to take (or, if the CREST member 
is a CREST personal member or sponsored member or has 
appointed a voting service provider, to procure that his 
CREST sponsor or voting service provider takes) such action 
as shall be necessary to ensure that a message is transmitted 
by means of the CREST system by any particular time. In this 
connection, CREST members and, where applicable, their 
CREST sponsor or voting service provider are referred in 
particular to those sections of the CREST Manual concerning 
practical limitations of the CREST system and timings.

The Company may treat as invalid a CREST Proxy Instruction 
in the circumstances set out in Regulation 35(5)(a) of the 
Uncertificated Securities Regulations 2001.

3.   If you wish to attend the AGM in person, you should make 
sure that you arrive at the venue for the AGM in good time 
before the commencement of the meeting. You may be asked 
to prove your identity in order to gain admission.

4.   A member who is entitled to attend, speak and vote at the 

AGM may appoint a proxy to attend, speak and vote instead 
of him. A member may appoint more than one proxy provided 
each proxy is appointed to exercise rights attached to 
different shares (so a member must have more than one share 
to be able to appoint more than one proxy). A proxy need not 
be a member of the Company but must attend the AGM in 
order to represent you. A proxy must vote in accordance with 
any instructions given by the member by whom the proxy is 
appointed. Appointing a proxy will not prevent a member from 
attending in person and voting at the AGM (although voting in 
person at the AGM will terminate the proxy appointment). A 
proxy form is enclosed. The notes to the proxy form include 
instructions on how to appoint the Chairman of the AGM or 
another person as a proxy. You can only appoint a proxy 
using the procedures set out in these Notes and in the notes 
to the proxy form.

5.   To be valid, a proxy form, and the original or duly certified 

copy of the power of attorney or other authority (if any) under 
which it is signed or authenticated, should reach the 
Company’s registrar, Capita Registrars, PXS, 34 Beckenham 
Road, Beckenham BR3 4TU, by no later than 10.00 a.m. on 
11 June 2013.

6.   In the case of joint holders of shares, the vote of the first 
named in the register of members who tenders a vote, 
whether in person or by proxy, shall be accepted to the 
exclusion of the votes of other joint holders.

7.   A member that is a company or other organisation not 

having a physical presence cannot attend in person but can 
appoint someone to represent it. This can be done in one of 
two ways: either by the appointment of a proxy (described in 
Notes 2 and 4 to 6 above) or of a corporate representative. 
Members considering the appointment of a corporate 
representative should check their own legal position, the 
Company’s articles of association and the relevant provision 
of the Companies Act 2006.

8.   The following documents are available for inspection at  

the registered office of the Company during usual business 
hours on any weekday (Saturday, Sunday or public holidays 
excluded) from the date of this notice until the conclusion of the 
AGM and will also be available for inspection at the place of the 
AGM from 9.00 am on the day of the AGM until its conclusion:

(a)  copies of the executive directors’ service contracts with 
the Company and any of its subsidiary undertakings; and

(b)  letters of appointment of the non-executive directors.
