A LEADER IN REAL-TIME,  
HIGH PERFORMANCE, 
DDOS PROTECTION.

Corero Network Security plc

 
 
 
Corero Network Security is a leader in  
real-time, high-performance Distributed 
Denial of Service (“DDoS”) defence solutions. 
Service providers, cloud providers and digital 
enterprises rely on Corero’s award winning 
SmartWall® Network Threat Defense System 
and Threat Defense Director (“SmartWall”) 
technology to eliminate the DDoS threat.  

THE IMPACT OF 
DDOS ATTACKS

62%of companies are forecasting  

an increase in DDoS spending1 

45%of companies consider 

DDoS to be a top cyber 
security concern2

43%of organisations received  

a DDoS attack3 

$250k (p/h)

revenue at risk in the face of  
a DDoS attack* 4

28%of organisations believe that large scale 

Terabit DDoS attacks such as the 
Memcached attacks in March 2018  
will become the “norm” 3

WHY IS THERE A NEED FOR BUSINESSES 
TO ADDRESS DDOS THREATS?

 High availability of Cloud services and 
applications are critical for modern businesses 
and institutions
  Any DDoS downtime brings risk:

 Lost revenue or loss of control
 Operational costs to mitigate or recover 
from attacks
 Increased costs to retain unhappy 
customers and attract new customers
 Brand and reputation damage leading  
to competitive disadvantage or loss  
of confidence 
 Regulatory fines, legal action, resignations

What is a DDoS attack 
A Distributed Denial of Service attack is a cyber threat, in which 
multiple computer systems attack a target, such as a server, 
website or other network asset, and cause a denial of service for 
users of the targeted resource. The flood of incoming messages, 
connection requests or malformed packets to the target system, 
forces it to slow down or shut down, thereby denying service to 
legitimate users or systems. DDoS attacks are a threat to service 
availability, network security, brand reputation and ultimately 
lead to lost revenues. 

Attackers are continuing to leverage DDoS attacks as part of 
their cyber threat arsenal to either disrupt business operations 
or provide a smokescreen while they access sensitive corporate 
information, and they are doing it in increasingly creative ways 
that circumvent traditional security solutions or reduce the 
previous effectiveness of DDoS scrubbing centres. 

DDoS attacks can be found in a multitude of sizes and are 
launched for any reason imaginable. They can now be used to 
expose vulnerabilities, to extort payments, and as a smokescreen-
like distraction for other nefarious activities. Today’s organised 
criminals are able to focus on the results that they want and simply 
buy or rent the malware or botnets they need to get there.

OverviewStrategic ReportGovernanceFinancial StatementsNotice of AGMCorporate DirectoryOUR PROPOSITION

What we do
Corero provides dedicated technology  
for real-time mitigation of DDoS attacks  
in seconds, versus the minutes taken by 
legacy	solutions,	allowing	good	user	traffic	
to	flow	uninterrupted.

How we do it
With varied deployment topologies (in-line, 
scrubbing, or directly on edge routers) the 
SmartWall family of solutions utilise 
innovative technology to automatically 
and	surgically	remove	DDoS	attack	traffic.	

Corero enables revenue protection, 
customer retention and competitive 
differentiation	in	the	face	of	DDoS	attacks,	
for Internet Service Provider, Cloud Provider 
and Digital Enterprise customers.

Protection	is	provided	in	cost	effective	
scaling increments from 1Gbps, 10Gbps  
and 100Gbps to tens-of-terabits,  
to support customers bandwidth and 
inspection requirements. 

The Corero solutions are among the highest 
performing in the industry, while providing 
the most automatic security coverage at 
unprecedented scale with the lowest total 
cost of ownership to the customer.

Corero enables Service Providers and Cloud 
Providers to protect their infrastructure 
from DDoS attacks and to deliver high value 
DDoS protection services to their customers, 
allowing for incremental service revenues. 

Corero has combined advances in Intel 
x86 multicore CPU technology, Data Plane 
Development Kit (“DPDK”) software for 
packet processing acceleration, and 
high-performance network interface cards 
(“NICs”), together with its innovative and 
highly	efficient	software	architecture,	to	
develop a new generation of appliances 
providing breakthrough price/performance 
for DDoS defence. 

SmartWall appliances perform sampled 
Deep Packet Inspection (“DPI”) to generate 
security	metadata	from	traffic	flows.	The	
internal rules engine examines this metadata 
to	flag	offending	packet	flows	in	real-time	and	
instantly block attacks. At the same time, the 
security metadata is streamed to the Corero 
SecureWatch Analytics platform, where 
further analysis, involving correlation with 
other performance metrics and event data, 
enables	rapid	identification	of	new	attack	
vectors. SecureWatch Analytics also 
formulates new mitigation rules for these 
vectors that are distributed out to each 
SmartWall instance.

Corero SecureWatch Analytics leverages 
Splunk’s analytics engine and provides 
robust reporting to transform 
sophisticated DDoS event data into easily 
consumable dashboards accessed via the 
SecureWatch Analytics web portal.  

Corero protects Digital Enterprises from 
DDoS attacks thereby ensuring availability 
and security of Internet services and 
applications essential for digital / on-line 
businesses and, in the process:

•  Protecting revenues by avoiding 

downtime and additional post DDoS 
attack remediation costs

•  Keeping customers happy and  

avoiding increased costs for retention  
of existing customers and acquisition  
of new customers

•  Protecting brand and reputation damage 

•  Avoiding the risk of non-compliance,  

legal	liability	and	fines.

The portal allows customer security 
operators to monitor and manage incident 
response, with the ability to conduct 
sophisticated forensic analysis.

Corero’s SmartWall solution is highly 
automated, detecting and mitigating 
attacks without the intervention of security 
analysts or network operators, who may 
not even know the network is under attack, 
unless they are monitoring Corero’s 
dashboard for alerts.

The Corero Service Portal enables a 
provider and their customers to gain 
visibility into attacks with per-tenant 
dashboards. Providers can assign tenant 
service levels and automatically distribute 
reports which showcase the value of the 
protection they are receiving. 

The Corero SecureWatch® service is a 
tiered	offering	comprised	of	configuration	
optimisation, monitoring and mitigation 
response services. These services, delivered 
by the Corero Security Operations Centre, 
are customised to meet the security policy 
requirements and business goals of each 
SmartWall customer.

Corero’s DDoS defence solution is more  
than	99%	effective	in	rapidly	detecting	and	
automatically mitigating real-world attacks 
within	seconds.	This	degree	of	effectiveness,	
speed and accuracy would not be possible 
without incorporating the results from a Big 
Data analytics engine that can perform 
analysis of high velocity security metadata.

Big Data analytics also provides the foundation 
for machine learning and AI techniques that 
can further improve the speed and 
effectiveness	of	DDoS	defence.	These	
techniques may prove very useful in thwarting 
future attacks that are more complex than 
those seen today.

Next-Generation DDoS Defence  
for the Expanding Internet Edge
Corero’s SmartWall solutions deliver high-
performance DDoS protection for customers that 
include shared hosting facilities, large enterprises, 
government agencies, critical infrastructure providers 
and cloud-native digital enterprises such as online 
gaming and SaaS providers. Service Providers and 
Cloud Providers can deploy SmartWall appliances 
always-on at the edge, or in scrubbing centres for 
on-demand mitigation; and are also deploying Corero 
as a key component of managed security service 
offerings.	These	customers	are	benefiting	from	
Corero’s ability to automatically detect and mitigate 
DDoS attacks in real-time with a platform that leads 
the industry in price/performance.

The SmartWall TDD software is an extension of the 
solution that was developed by Corero to meet the 
demand for massive-scale, tens-of-terabits, mitigation 
by	innovatively	leveraging	the	built-in	filtering	power 
of Juniper Networks’ latest generation of 
infrastructure edge routing devices. This Juniper-
Corero network-based DDoS defence solution can be 
deployed by any provider, large and small, but is 
particularly well-suited for mitigating attacks in 
large-scale networks supporting a large number of 
high speed links (10 Gbps – 100 Gbps) and large 
numbers of routers at the Internet edge.

OverviewStrategic ReportGovernanceFinancial StatementsNotice of AGMCorporate DirectoryCHIEF EXECUTIVE’S STRATEGIC UPDATE

“ Corero is well positioned to deliver  
on its goal of being the leading  
player in the real-time DDoS mitigation 
market with SmartWall solution 
validation from over 100 customers 
and a growing number of GTM  
partners including Juniper Networks 
and GTT Communications.”
  Ashley Stephenson, Corero CEO 

Results
Corero revenue for the year ended  
31 December 2018 was $10.0 million  
(2017: $8.5 million) up 16.6% over the prior 
year. Recurring revenue increased to $5.1 
million (2017: $4.0 million). The EBITDA loss 
reduced significantly to $2.1 million (2017: 
restated EBITDA loss $5.0 million). 

Revenue growth and progress towards 
EBITDA break-even was impacted by the 
longer time required to enable new 
go-to-market partners and secure 
contracts. However, we expect this to 
ramp-up in 2019. 

Operating performance

the largest DDoS attack will be broken in 
the future, it’s difficult to predict when this 
will happen or if it will in 2019. However, we 
can confidently say that the need for 
organisations to deploy solutions which 
provide real-time mitigation of DDoS 
attacks will increase. These solutions allow 
organisations to eliminate attacks in 
real-time, allowing good user traffic to flow 
uninterrupted, and avoid the risk of costly 
outages or downtime.

Organisations will become 
more proactive with security 
and actively cooperate with  
security vendors 
As awareness around cybersecurity 
increases and regulations like GDPR and  
the NIS Directive are brought into force, 
organisations will become more proactive 
with their security. Organisations will start 
taking a more risk-based approach to 
security where they assess which threats 
could pose the most damage to their 
businesses and working to prioritise 
security to defend against these incidents. 
Organisations will also become more 
dependent on vendor collaboration,  
where security companies combine their 
expertise to develop robust, state-of-the-
art security protection.

The security of Critical  
National Infrastructure  
will become a top concern 
As critical national infrastructure (CNI) 
organisations become more reliant on the 
Internet, and the IoT, to conduct operations, 
the risk of these systems falling victim to 
attack will increase. However, awareness  
of security within CNI organisations is 
increasing and will continue to do so in 2019. 

Botnets will continue to  
feature heavily in the growing 
threat landscape
Despite the upcoming introduction of 
legislation around security for connected 
devices, IoT devices will still be a key target 
for attackers building botnets. These IoT 
devices will still be recruited to build large 
botnets, similar to that of Mirai in 2016, and 
used to launch massive DDoS attacks. This is 
why botnets will still be a key concern for 
security professionals throughout 2019.

We can confidently say that the need for organisations  
to deploy solutions which provide real-time mitigation  
of DDoS attacks will increase.

CHIEF EXECUTIVE’S STRATEGIC UPDATE CONTINUED

“ I am delighted to announce the agreement of a global  
go-to-market partnership with Juniper Networks for 
the sale and support of Corero SmartWall software and 
services in conjunction with Juniper’s MX Series. 
Many of our common customers have independently 
deployed Juniper and Corero products to protect their 
networks against DDoS attacks. This new partnership 
extends the scalability and automation of DDoS protection 
to unprecedented price-performance levels, securing these 
networks in real time against large-scale attacks.”
Ashley Stephenson, Corero CEO

25bnIoT-connected 
devices by 2021 
(Internet World Stats) 

Along with email spam, phishing, malware, 
DDoS attacks remain a persistent blight  
on the Internet. Technically sophisticated 
attackers using automated methods for 
launching attacks have escalated from an 
occasional but often severe nuisance into a 
widespread, ever-present and constantly 
worsening threat. Corero’s Full Year 2018 
DDoS Trends Report shows the average 
number of attacks per customer was up 
16% over 2017.

An ever-expanding attack surface

The vast complex of public networks 
spanning the globe is constantly growing 
and evolving, reaching into every corner of 
society. New users, endpoints and networks 
come online every hour of every day, 
presenting bad actors with a constantly 
expanding surface with new targets 
potentially vulnerable to attacks or 
exploitable for launching them.

Financially motivated criminal organisations 
and nation state actors bent on cyber warfare 
have combined forces with malicious hackers 
to pool knowledge and experience to launch 
increasingly complex, multi-vector attacks 
that are more difficult to detect and mitigate. 
The vast majority of DDoS attacks are still 
either volumetric in nature – consuming a 
high percentage of network bandwidth – or 
focused on exhausting protocol-processing 
resources in the host systems under attack. 
Both types are highly effective in knocking  
out Internet applications and services, for 
minutes to sometimes hours and with 
negative consequences for service providers, 
businesses and consumers.

A clear and present danger

Attacks are often launched utilising large-
scale botnets that attackers create by 
hijacking poorly secured endpoints, including 
servers, PCs, laptops and, in recent years, 
consumer IoT devices such as webcams. The 
majority (according to Verizon, over 75%)  
still leverage amplification techniques  
that jack up attack intensity by exploiting 
vulnerabilities in Internet services and host 
systems to increase the flood of traffic 
directed at targets.

10

Internet evolution is shifting the DDoS 
battlefield in two directions: out toward  
the rapidly growing IoT edge and up into  
the hyperscale datacentres supporting  
the ever-expanding cloud.

“  Growth in revenue,  
retention of existing  
clients and broadened  
go-to-market strategy  
support our 2019  
growth ambitions.”

RISE OF IOT  
DRAMATICALLY 
INCREASES THE 
ATTACK SURFACE 

The Internet of Things (IoT) and the 
proliferation of its relatively cheap 
internet-enabled devices has opened up a 
whole new opportunity for cybercriminals 
over recent years. Despite its advantages, 
IoT comes with a host of security 
challenges. The manufacturers of IoT 
devices have been mainly focused on 
speed to market, for their next ‘must-have’ 
product. Security of these devices has not 
been a priority and, as a result, they are 
typically equipped with the most basic of, 
easily bypassed, protection. This makes 
them prime targets for hacker infiltration 
and takeover, aside from the personal 
privacy and security concerns that result 
from these security gaps.

Exploitation of these devices, en masse, for 
DDoS attacks first came to light in late 2016 
with ‘Mirai’, a now infamous botnet 
consisting of hundreds of thousands of IoT 
devices. Mirai itself was used to launch the 
well-publicised attack on Dyn, the Internet 
DNS provider, which took down the 
websites and services of many of the 

largest names on the Internet, for users 
on the Eastern seaboard of America, for 
several hours. Since then, publication of 
the source-code by its author has led to 
many variants, of increasing sophistication 
and potency.

The real game changer here is the low 
barrier to entry this now presents for  
those intent on launching damaging DDoS 
attacks. The ability to take and modify the 
existing Mirai code reduces the level of 

knowledge required by a would-be 
cybercriminal. And, the simple to use 
interfaces they add to these botnets to  
turn them into DDoS-for-hire services 
means that anyone with a motive can now 
leverage them to launch damaging attacks, 
often for as little as a few dollars an hour.

The costs are heavily weighted in favour of 
those launching attacks – with lost business 
and recovery costs for the victims typically 
reaching six figures and more.

“ Massive attacks fuelled by billions of connected devices are 
the future, and the entire industry is investing and gearing up 
solutions to protect against this new generation of attacks.  
The move to 5G infrastructure will only compound the problems, 
greatly increasing the bandwidth for connected mobile devices 
(and the volume of attack traffic they can generate).”

CHIEF EXECUTIVE’S STRATEGIC UPDATE CONTINUED

Rapid IoT adoption is driving a proliferation 
of intelligent devices that will ultimately 
exceed the number of user endpoints. 
Machine-to-machine connections from  
the edge will power a wide range of IoT 
applications, healthcare, environmental 
sensing and “smart” infrastructure – 
cities, buildings, homes and vehicles. 
Cybercriminals have already hijacked 
consumer IoT devices to create large-scale 
botnets and emerging mission-critical  
IoT networks will become targets for 
potentially catastrophic DDoS attacks.

Cloud-based services supporting mobile 
apps, streaming video, e-commerce, SaaS 
and enterprise IT are growing at an 
astounding rate, deployed in massive 
hyperscale data centres consisting of 
thousands of servers, which are both 
targets for attack and potential launch 
platforms. Content delivery networks 
(CDNs), that are instrumental in scaling 
cloud service delivery, are also targets for 
crippling attacks that can disrupt services 
for millions of users.

Bandwidth at the Internet edge continues 
to scale up. Gigabit consumer broadband is 
here, now. Multi-gigabit wireless over 5G 
networks is just over the horizon. More 
bandwidth at the edge is driving more 
capacity in the backbone. Service provider 
Internet connections are moving from 
10Gbps to 100Gbps. A faster edge enables 
higher intensity attacks, and fewer 
endpoints are needed to launch crippling 
volumetric attacks.

The never-ending battle

DDoS defence is still a never-ending battle. 
Attackers discover and exploit vulnerable 
hosts or services to launch attacks. 
Defenders monitor network activity to 
compile a catalogue of attack profiles that 
are then used to generate rules to detect 
and identify attacks to take the necessary 
mitigation actions.

Massive-scale, high-intensity DDoS attacks 
measured in hundreds of gigabits, and now 
even into the terabits, make headlines, but 
the every day battle is fought in an endless 
series of smaller-scale skirmishes. High-
intensity attacks may rise for a period of 
time but then attackers are forced to 
regroup as network defences are mounted 
and operators reconfigure or protect 
vulnerable hosts. Yet the DDoS attack-and-

defend cycle continues, with no end in sight, 
because there is no foolproof method to 
eradicate attacks. The Internet is too vast, 
complex, decentralised and constantly 
evolving. Defenders need to be ever-vigilant 
– individually and collectively – to deal with 
attacks when, not if, they occur.

Opportunities for Corero
Adoption of faster 100Gbps links 

As transit providers start pushing tenants 
towards using fractional committed data 
rates on 100Gbps connections, for cost and 
efficiency, versus two or more individual 
10Gbps connections, we expect increased 
adoption of 100Gbps links. The challenge with 
faster 100Gbps links is that tenants can then 
be hit by up to 100Gbps of attack traffic, even 
if they are only subscribing to 20Gbps of 
regular capacity. 

We anticipate demand for Corero’s 
SmartWall 100Gbps technology to 
accelerate as a result of this and increasing 
end-user service-level expectations 
resulting in the requirement for Service 
Providers, Cloud Providers and Enterprises 
to deploy DDoS mitigation technology 
upgrades. Corero’s 100Gbps line-rate 
appliance ensures each 100Gbps connection 
can be automatically protected from DDoS, 
without impacting legitimate traffic.

5G will increase DDoS attack risk

Telecoms providers are in a race to 
rollout 5G services that will empower 
smart devices and the IoT. The new 
telecommunications infrastructure 
required to enable it will bring a huge leap 
in the available bandwidth. This will enable 
end-users (both machine and human) to 
experience much faster access and 
downloads, and share more data across 
more devices.

Along with the benefits and opportunities 
come new cybersecurity risks. For example, 
as more powerful smart devices come 
online, the networks hosting these devices 
will have an increased attack surface, which 
makes them bigger targets for malware, 
security breaches and, of course, DDoS 
attacks. It also increases the opportunity 
for those devices to be harnessed for the 
purposes of launching damaging DDoS 
attacks against other targets.

EMERGING 
EVIDENCE OF 
INDISCRIMINATE 
DDOS ATTACKS

During 2018 Corero observed evidence of attacks that 
disrupt larger numbers of victims but exhibit no obvious  
or specific targeting.

Questions being asked are:
•  Are the attacks trying to disrupt the 

Internet in general?

•  Are they broad anti-establishment or 

anti-nation attacks?

•  Are the attacks spread out over wide 

ranges to avoid legacy detection 
techniques?

•  Are the attacks a side effect of increased 
use of more aggressive scanning tools?

•  Are the observed traffic levels side effects 
of targeted campaigns causing indirect 
damage as they are leveraged to attack 
third parties?

The current assumption is that it’s  
most likely a mix of several of the  
above scenarios.

In November 2018, during a 24 hour period, 
tens of thousands of IP addresses spanning 
a wide range of unrelated sites, were 
observed to be the target of excessive 
traffic rates from the Internet.

The suspicious traffic appeared to be  
part of the same event. The traffic levels 
were sufficiently elevated to cause an 
unprotected site to suffer a service impact 
or an outage. It was not possible to account 
for the number of victims impacted by this 
incident but it is considered likely that the 
vast majority of target sites were not 
explicitly selected.

 The Internet-connected world has grown more complex due 
to faster connections, the widespread adoption of Internet 
of Things (IoT) devices, and cloud services. Simultaneously, 
DDoS threats have become more sophisticated and frequent. 
Whilst unlawful in many countries, DDoS-for-hire services are 
commonplace and inexpensive.

5G will power more virtual reality, 
artificial intelligence, remote surgery, 
and automated machinery, all of which 
will rely on highly available and low 
latency connectivity. Downtime or service 
disruption for networks that support 
these critical applications will become 
increasingly disastrous (or, at the very 
least, much less tolerated).

Any organisation which relies on the 
Internet for its business, needs to be 
prepared for the increased cyber risks that 
5G brings. In particular, Internet Service 
Providers now face a significant challenge, 
securing their increasingly complex and 
exponentially faster networks in an era 
where DDoS attacks have grown in 
frequency and sophistication. It will be 
critical that they prevent DDoS traffic from 
disrupting their own network-based service 
offerings, as well as those of their customers.

Super-scale DDoS protection

Carriers and other Tier-1 Service Providers 
have traditionally adopted a bifurcated 
approach to DDoS protection, for reasons 
of cost and the practicalities of deploying 
the available protection solutions. This 
two-tier service results in only the smaller 
DDoS attacks being filtered out, with larger 
attacks being addressed by blocking all 
traffic headed for the target, taking them 
offline for the duration. This may have 
been more accepted in the past but, as 
organisations increasingly rely on their 
Internet presence being available 24/7, 
this presents an increasing challenge for 
service providers.

Recent advances in the inherent traffic 
filtering capabilities of network routers, 
from vendors such as Juniper Networks, is 
enabling a new generation of protection. 
Security solutions can now leverage next 
generation router filtering to deliver 
super-scale protection directly at the 
perimeter of a network.

We believe that Corero is the first DDoS 
vendor to effectively leverage real-time 
infrastructure-based traffic-filtering,  
which is enabling protection to be extended 
to an unprecedented tens-of-terabits scale. 
Combined with Corero’s highly automated 
approach, providers can deliver this 
super-scale protection at a price-point  
that was not previously possible.

Corero Network Security plc Annual Report and Accounts 2018KEY INSIGHT

INCREASE IN  
THE USE OF  
MULTI-VECTOR  
ATTACKS

Multi-Vector vs.  
Single-Vector Attacks
There was an increase of 29% in the use of 
multi-vector attacks in 2018 compared to 
2017. Multi-vector attacks present several 
additional challenges for both detection 
and mitigation for the following reasons. 

•  For complete mitigation it is necessary 
to recognise each and every vector and 
respond with the appropriate mitigation 
without impacting legitimate traffic.

•  Multi-vector attack rates are usually 

additive in terms of bandwidth and packet 
rate. The total attack rate will be the sum 
of vector1 + vector2 + vector3 etc. 

•  Multi-vector attacks often exhibit 

more variability in rate, as different 
vectors join and leave the attack. This 
presents challenges for many traditional 
detect-and-redirect DDoS solutions that 
typically provide partial mitigation 
capacity. Making a decision on the 
mitigation method (e.g. redirection vs. 
blackhole) based on the current attack 
rate is flawed as this can vary on a 
minute by minute basis.

Multi-vector attack example 
•  The most common contributors to 
multi-vector attacks continue to be 
volumetric UDP amplification vectors 
including DNS, NTP, Chargen, SSDP  
and CLDAP. 

•  Attackers frequently mix resource 

exhausting TCP SYN floods from spoofed 
sources to make tracking more 
challenging. 

•  These vectors, and other variants,  

are added or subtracted multiple times 
during a typical 10 minute attack period. 
The aggregate amplitude may vary up  
to 10X during the attack as vectors surge 
and fade. 

Internet resilience can come down to a  
fraction of a second. When the Internet goes  
down, businesses that rely on that service go down 
with it, and DDoS attacks are considered one of the 
most serious threats to Internet availability today. 
Downtime or latency can significantly impact brand 
reputation, customer trust and revenue. Within 
Europe, the introduction of the GDPR and NIS 
legislation has significantly increased the  
risk of punitive fines for cyber-resilience failures.

MARKET OVERVIEW

DDOS ATTACKS ARE ACCELERATING IN PURPOSE,  
SOPHISTICATION, COMPLEXITY, SCALE AND FREQUENCY.

A wide range of critical cybersecurity issues 
face every Internet connected organisation. 
These threats include denial of service, 
hacking, breach, phishing, fraud, data theft 
and exfiltration. These threat vectors 
present themselves via the essential 
Internet connections that are required to 
support the online business.

Today, the vast majority of leading Internet 
service providers sell raw Internet transit 
capacity. This raw capacity, usually sold via 
1Gbps, 10Gbps and increasingly 100Gbps 
transport connections, carries good 
customer traffic and malicious bad traffic 
without discrimination. If an enterprise, 
data centre, or hosting facility connects to 
these raw transit providers they will be 
exposed to Internet-borne cyber threats 
and their information security posture 
should be prepared to detect and protect 
against any associated malicious intent.

Corero focuses on one specific category of 
these cyber threats encompassing denial of 
service and has developed a real-time DDoS 
detection and mitigation solution that 
delivers automatic detection and protection 
against DDoS attacks. 

Businesses and public-sector organisations 
are vulnerable to DDoS attacks and recent 
years have seen some of the world’s 
best-known companies fall victim with,  
in some cases, catastrophic impact for  
their customers. 

The broad range of motives for executing 
DDoS attacks, coupled with the relative 
ease with which they can be performed, 
means that they are carried out by a huge 
variety of actors, including; criminal gangs, 
activists, terrorist groups and nation state 
“bad actors”. Aside from those who are 
focused purely on disrupting services, many 
of those who carry out DDoS attacks do so 
for extortion, as a way to expose other 
vulnerabilities, or as a smokescreen to 
steal data, or plant malware.

While the frequency of attacks is concerning, their size 
and duration are also important to highlight. 

•  98% of mitigated DDoS attacks were less than 10Gbps  

in volume in 2018 (2017: 99%).

•  The nature of the DDoS threat landscape is the reason 
attack size and duration remains the primary factor in 
organisations choosing a DDoS Protection solution. 

•  The continuing trend is that attacks are getting shorter. 
In 2018, 81% of attacks lasted less than 10 minutes; up 
from 71% in 2017. 

•  The long-term trend of a reduction in the percentage of 
attacks over 20 minutes continues with further decline 
in average duration. In 2018, only 12% of attacks lasted 
longer than 20 minutes; down from 19% in 2017. 

In summary, attacks below 10Gbps and short duration 
attacks continue to dominate with these attacks 
trending larger and shorter to evade traditional 
protection methods. Only fast acting, automatic, 
solutions are able to defend against such attacks.

“ One of the main drivers for DDoS prevention  
investment is the “increasing volume of highly  
visible attacks, including a mix of politically motivated 
attacks, state-sponsored electronic warfare, social 
activism, organised crime, and good old fashioned 
pointless mischief and mayhem, driven by the  
easy availability of bots/botnets for hire and easily 
distributed crowd-sourced attack tools.”

Routes to market
Corero has, in 2018, focused on developing 
and expanding its routes to market which 
include:

•  Direct sales: Corero sales team selling 
directly in its chosen markets of North 
America, Europe, and Australia (in certain 
markets channel partners are used for 
order fulfilment);

•  Indirect sales: Value added resellers and 

distributors selling the SmartWall solution 
to their customer base; and 

•  Partner sales: The principal partners 

SecureWatch managed services include:

•  Software updates delivered to the Corero 

appliances and software instances in 
customer networks, to provide proactive 
on-going protection from the latest DDoS 
threats; and 

•  24x7x365 monitoring and support services 
including DDoS attack mitigation tuning 
delivered by the highly experienced 
Corero Security Operations Centre team.

include Juniper and GTT Communications 
who resell the Corero SmartWall solution 
or a DDoS protection service to their 
customers thereby leveraging these 
partner’s customer and geographic 
market reach. Further go-to-market 
partner relationships will be developed 
to amplify Corero’s market reach. 

Corero sells the SmartWall technology to 
customers in the form of either (a) an 
appliance sale and perpetual software 
license, plus annual SecureWatch services, 
(b) as a software subscription for its virtual 
appliance software, or (c) as-a-service which 
enables the customer to utilise the 
technology on a subscription or revenue 
share basis (without owning the appliance 
and software).

EXECUTING ON THREE-PRONGED GO-TO-MARKET FOCUS.

THE CORERO STRATEGY IS TO DEVELOP 
SOFTWARE AND PROVIDE SERVICES TO 
PROTECT AGAINST A CONTINUOUSLY EVOLVING 
DDOS ATTACK LANDSCAPE THAT THREATENS 
ANY INTERNET CONNECTED BUSINESS,  
OR THE PROVIDERS THAT SERVE THEM.

Scaling the business  
towards profitability
•  Three-pronged go-to-market focus:

Investment in sales and 
marketing to drive growth
•  Sales investment to support growth plans

 – Direct sales: Corero sales team  

focused on the SmartWall target  
market to leverage success to date

 – Indirect sales: channel partner 

proposition

 – Partner sales: close engagement  

with go-to-market partners such as 
Juniper and GTT Communications and 
development of additional partner 
relationships

•  Channel leverage: utilise Juniper channel 
partners given close alignment between 
Corero and Juniper’s customer focus 
(service providers, cloud providers and 
digital enterprises) 

•  Marketing spend focused on new 
customer sales lead generation

Maintaining competitive 
advantage
•  Incremental product enhancements  

with stable R&D investment 

 – New DDoS attack defences

 – New machine learning and artificial 

intelligence capabilities

Continuing to focus on 
customer delight
•  Superior customer service and support

•  Target world class support and services 

renewal rates of >90%

“ Providers are facing the challenge of securing increasingly 
complex and exponentially faster networks. By leveraging 
Corero’s SmartWall DDoS detection and mitigation technology  
to automatically control Juniper’s SDN-enabled MX Series,  
we are able to offer an integrated solution that protects the 
Provider Edge against the increasing risk posed by DDoS  
attacks. Juniper’s expanded relationship with Corero provides  
our customers with additional security options to make the  
self-driving network a reality.” 

Wayne Cheung, Product Marketing Director, Juniper Networks

“ Juniper Networks  
provides the routing 
infrastructure for some  
of the world’s largest and  
most critical IP networks, 
including key subscriber, 
mobile, enterprise, 
government, and academic 
networks. “This partnership 
raises the bar for automated, 
scalable and secure IP 
networks by integrating 
Juniper’s proven routing 
technology and Corero’s  
high-performance DDoS 
protection, and delivering  
the combined solution to  
large, strategic customers 
through Juniper’s global  
sales force and channel.”

Corero Network Security plc Annual Report and Accounts 2018PRINCIPAL RISKS AND UNCERTAINTIES

CORERO IS DEPENDENT ON REVENUE GROWTH TO DELIVER ON ITS STRATEGY.
LOWER SALES GROWTH WILL REDUCE THE COMPANY’S CASH RESOURCES 
WHICH COULD IMPACT THE INVESTMENT IN PRODUCT DEVELOPMENT.

Market 
awareness

Technology 
change and 
innovation

People

Sales 
growth

The Company manages these risks by monitoring the key 
performance indicators which are set out on pages 26 and 27. 

Corero is an emerging player 
in the DDoS prevention 
market and competes with 
much larger organisations. If 
Corero is not successful in 
connecting with the market 
and raising its profile this will 
compromise growth plans. 

To raise market awareness 
of Corero and its DDoS 
mitigation solutions, the 
Group will invest in targeted 
digital marketing and lead 
generation programs. 

The DDoS mitigation 
market is competitive and 
characterised by constant 
changes in technology, 
customer requirements 
and frequent new product 
introductions and 
improvements. 
Cybersecurity and DDoS 
attacks are constantly 
evolving and changing as 
attackers develop new 
methods and tools to evade 
defences. 

Corero is focused on its 
chosen markets and 
delivering continuous 
innovation by adding new 
DDoS attack defences and 
new machine learning and 
artificial intelligence 
capabilities.

Retaining and recruiting 
people with the necessary 
skills and experience. To grow 
and address the challenges 
resulting from technology 
change and innovation in  
the DDoS mitigation market, 
the Company needs to retain 
and recruit the required 
sales, business development, 
and technical product 
development skills. Corero 
operates in a high growth 
market with new players 
emerging. If Corero is unable 
to recruit and retain the 
right skills this will 
compromise growth plans.

Corero targets paying in 
the upper quartile for 
comparable positions and 
has a share options plan to 
provide an incentive for 
employees.

Corero’s business success 
depends on growing 
SmartWall product and 
SecureWatch and DDPaaS 
service sales to new 
customers in its target 
market of service providers, 
cloud providers and digital 
enterprises. If Corero is not 
successful in identifying 
customer prospects with  
a business need Corero  
can solve, or developing 
go-to-market partner and 
channel partner relationships 
which generate revenue, this 
will compromise growth 
plans and success. 

To be successful Corero will:

•  Focus its lead generation 
and sales resources, and 
product development, on 
its target markets 

•  Work closely with 

go-to-market partners 
and in particular with 
Juniper to progress sales 
opportunities and 
generate revenue

•  Develop relationships 
with go-to-market 
partners, channel 
partners and system 
integrators to expand its 
routes to market.

Brexit
The impact of Brexit, whilst giving rise to 
uncertainty, is not expected to have a 
significant impact on Corero.

•  EU customer impact. In the year ended 
31 December 2018, 7.5% (2017: 4.4%) of 
Corero’s order intake was generated from 
customers in the EU (excluding the UK), 
and 25.4% from customers in the UK 
(2017: 21.9%). Any potential short-term 
Brexit related impact on the movement 
of goods from the UK is not expected to 
materially impact Corero as hardware 
products can be shipped to EU based 
customers from Corero’s US subsidiary. 

•  The risk of a downturn in the  

UK and EU economies.  
Brexit may impact economic conditions in 
the UK and EU which may have an impact 
of customer’s IT budgets. It is too early to 
forecast whether such an impact would 
materially impact Corero’s business.

•  Sustained reduction in the value of 
GBP sterling. Corero equity fund raises 
are in GBP and its debt is denominated in 
GBP. To the extent such funds are required 
to support US dollar denominated funding 
requirements, the lower value of GBP 
reduces the value of US dollar denominated 
funding requirements that can be funded 
from such fund raises. The Group mitigates 
this risk by utilising US denominated funds 
received by the Group’s UK subsidiary to 
fund the Group’s US subsidiary to the 
extent such funding is required, with the 
GBP funding requirements satisfied from 
the GBP denominated funds generated 
from GBP equity and debt fund raises. 

•  EU citizen employees UK working 

rights. Corero’s UK workforce includes 
EU citizens. The UK government has as 
part of the Brexit negotiations made a 
commitment to allow EU workers 
employed at the date of Brexit to apply 
for “settled status in the UK”. However, 
the uncertainty regarding Brexit is having 
a negative impact on such EU citizens. 
Corero believes such uncertainty can be 
managed and the sufficient talent will be 
available post Brexit albeit that salary 
costs may increase.

“ We welcome the investment  
from a global corporation of  
Juniper Network’s reputation  
and scale, in addition to our 
previously announced global  
resale partnership. 
We feel this represents a  
further endorsement of our  
vision for SmartWall products  
as a critical component in securing  
IT networks from DDoS attacks.  
We look forward to working  
closely with Juniper to capitalise  
on our partnership and jointly 
pursuing the market opportunity 
for DDoS protection via its global 
sales force and channel.”

Ashley Stephenson, 
Corero CEO

Corero Network Security plc Annual Report and Accounts 2018FINANCIAL REVIEW

CORERO ENDED THE YEAR 
STRONGLY, WITH A RECORD  
FINAL QUARTER ORDER INTAKE 

The 2018 operating loss of $5.0 million (2017: 
restated loss $8.5 million2) includes amortisation 
of capitalised development expenditure of $2.9 
million (2017: $2.4 million). $1.7 million was spent 
on the continuing development of the 
SmartWall product portfolio (2017: $2.2 million).

The loss for the year after taxation 
amounted to $5.2 million (2017: restated 
loss $8.4 million2) and includes: 

•  Unrealised exchange gain of  

$0.4 million (2017: loss $0.6 million)  
arising on an intercompany loan;

•  Finance costs of $0.3 million  

(2017: $0.004 million).

The loss for the year reflects the 
continuing investment in Corero’s 
technology and sales and marketing 
activities. Corero is focused on delivering 
accelerated sales growth through 
expanded routes to market, which, with 
gross margins exceeding 75%, is expected 
to result in improved profitability and 
targeted EBITDA breakeven by the end 
of 2019.

•  Loss per share 1.4 cents (2017: restated 

loss per share 3.0 cents2)

•  Group’s net assets at 31 December 2018 

$19.0 million (2017: restated $17.6 million2)

Chief Financial Officer

10 April 2019

“ The Corero management  
team is focused on delivering  
on its objective of being  
EBITDA profitable and cash 
generating by the end of 2019.”

Revenue growth and progress towards 
EBITDA break-even was impacted by the 
longer time required to ramp up new 
go-to-market partners and secure contracts. 

Despite this, the EBITDA loss1 decreased by 
57.9% over the prior year as a result of a 
16.6% increase in revenue and 13.3% 
reduction in adjusted operating expenses3 in 
the year with a focus on cost management.

CHAIRMAN’S INTRODUCTION

CORERO IS WELL PLACED  
FOR ACCELERATED GROWTH.

“ I am pleased to present  
Corero’s Corporate Governance 
Report for the year ended  
31 December 2018.”

Board commitment  
to governance
The Board is committed to upholding high 
standards of corporate governance, 
protecting and growing shareholder value, 
and engaging in a fair and transparent 
manner with all of the Group’s stakeholders. 

The Board therefore supports and is 
committed to the principles of the QCA 
Corporate Governance Code which was 
published on 25 April 2018 and which has 
been applied by Corero with effect from  
28 September 2018.

The Board takes responsibility for 
approving the Group’s long-term goals and 
strategies, and provides overall financial 
and organisational control. The Board also 
ensures that the Group has appropriate 
and effective internal control and risk 
management systems.

Board leadership  
and effectiveness 
The Board recognises that to remain 
effective it must ensure that it has the right 
balance of skills, experience, knowledge and 
independence to enable it to discharge its 
duties and responsibilities. The Directors 
believe in the necessity for challenge and 
debate in the boardroom and consider that 
existing Board dynamics and processes 
encourage honest and open debate with 
the Executive Directors. We have for the 
first time conducted an internal Board 
evaluation review earlier this calendar year. 
The review showed that the Board is 
operating effectively. 

Board composition
The Board currently comprises two executive 
Directors and three Non-Executive Directors 
(including the Chairman), two of whom are 
independent. Peter George was appointed to 

the Board on 3 January 2019 to both broaden 
our US reach and deliver a greater balance of 
independence to our Board.

The notice of AGM will include a resolution 
to reappoint Richard Last and Ashley 
Stephenson who retire by rotation in 
accordance with the Company’s Articles  
of Association, and Peter George who was 
appointed since the last AGM.

Our culture
Successful companies have a strong culture 
and deeply rooted shared values. In common 
with most intellectual property businesses, 
at Corero, we know that the skills, 
experiences and passion of our employees 
are genuinely what make our products and 
services market leading. The Corero culture 
has been shaped by both our long-standing 
experience in the United States and our 
more recent expansion into Europe.

With a growing business, the level of team 
diversity and multi-site operations, we have 
recognised the importance of our culture 
and values. Corero’s agreed values, which 
have been defined in conjunction with our 
employees, are:

•  Integrity

•  Customer delight

•  Innovation

•  Open and honest communications

•  Empowerment

Corero has invested in an online tool, 
known as Kudos, which is being used to 
acknowledge, reinforce and measure the 
values-supporting behaviours and actions 
taken by Corero team members.

The Board undertakes informal enquiries  
of employees to ensure these values are 
upheld and promoted to ensure a healthy 
corporate culture. Board meetings are  
held at Corero’s offices in the US and UK 
which gives the Board the opportunity  
to informally interact with employees  
based at those office locations.

2018 performance
Corero’s revenue of $10.0 million for the 
year ended 31 December 2018 was below 
expectations as a result of the longer time 

required to ramp up new go-to-market 
partners and secure contracts. Corero has 
continued to manage its cost base with 
adjusted operating expenses in 2018 13.3% 
below the prior year; this contributed to the 
significant reduction in the Group EBITDA 
loss for the year of $2.1 million (2017: 
restated EBITDA loss $5.0 million). 

To achieve the stated goal of being EBITDA 
positive and cash generative by the end of 
2019, the focus for Corero is to scale its 
revenue by executing on its three-pronged 
go-to-market focus of direct sales, indirect 
channel sales and partner sales. 

In order to capitalise on the recently 
announced global resale partnership 
agreement with Juniper and to focus on 
maximising revenues from both direct and 
new go-to-market indirect sales channels, 
Corero intends to expand its US-based 
management team which will include the 
appointment of a head of global sales. 

Strategic focus
Corero is focused on delivering a step 
change in revenue and scaling the business 
for profitability. In SmartWall, Corero has  
a market leading product and the 
development focus is to maintain this 
competitive advantage.

Looking ahead
Corero enters 2019 against a backdrop  
of positive momentum underpinned by  
a broader go-to-market strategy and  
a stronger new business pipeline. 
Management is focused on delivering 
revenue growth, adding new customers, 
and targeting being EBITDA positive and 
cash generative by the end of 2019.

I would like to give thanks to our 
institutional and private investors for  
their continued support. Finally, thank  
you to all our employees for their hard  
work and commitment.

NEEDS AND EXPECTATIONS

Corero’s strategy is focused on the following key areas:

•  Scaling the business for profitability

•  Investment in sales and marketing to drive sales growth 

•  Maintaining competitive advantage

•  Continuing to focus on customer satisfaction

The Company is focused on maintaining high gross margins, 
a high proportion of recurring revenue, and an appropriate 
operating cost base with the goal of being EBITDA profitable 
and cash generating by the end of 2019. 

The key challenges in the execution of the Company’s strategy, 
and risk factors, are:

•  Sales growth 

•  Market awareness

•  Technology change and innovation

•  Retention of senior management and employees

All of these are covered in greater detail in the Strategic 
Report on pages 8 to 27.

Corero is committed to listening and communicating openly 
with its shareholders to ensure that is strategy, business 
model and performance are clearly understood. 
Understanding the views of analysts and investors, and 
seeking an active dialogue to help these audiences understand 
the Corero business, is important to driving the business 
forward. Corero does this via investor roadshows, attending 
investor conferences and regular financial reporting. 

Corero engages with shareholders in the following ways:

•  Meetings with institutional and material private 

shareholders (those holding more than 1% of Corero 
issued shares) as part of the year end and interim results 
announcement roadshows. The Board is kept informed of 
the views and concerns of any major shareholders, with any 
significant reports from analysts circulated to the Board. 

•  The Chairman meets with major shareholders at least annually.

•  Attendance at private investor conferences and forums. 
Shareholders will be informed of such events by Corero 
issuing an RNS Reach announcement.

•  Corero utilises both regulatory and non-regulatory channels 
to keep shareholders informed on Company progress and 
performance.

•  Corero engages with shareholders and responds to 

questions sent by email to investorrelations@corero.com.

In addition, Corero’s AGM is a forum for dialogue with all 
shareholders. The Notice of AGM is sent to shareholders at 
least 21 days prior to the meeting.

Corero’s web site, under the “Investors” section, contains 
information to satisfy shareholder needs. 

Andrew Miller, Corero’s CFO, is primarily responsible  
for shareholder liaison. Andrew can be contacted on

EMBED EFFECTIVE RISK 
MANAGEMENT, CONSIDERING 
BOTH OPPORTUNITIES AND 
THREATS, THROUGHOUT  
THE ORGANISATION

Corero recognises that long-term success is underpinned 
by good relations with its key stakeholders, both internal 
(workforce) and external (suppliers, customers, regulators 
and others). As part of Corero’s annual planning and budgeting 
process, the Company identifies its stakeholders and their 
respective needs, interests and expectations. In addition, 
the strategy for engaging with these stakeholder groups is 
formulated and implemented. Corero values feedback from 
its stakeholders and proactively endeavours to address any 
matter identified. To date feedback has been gathered from: 
customers and partner feedback relating to Corero’s products 
and services; employees as part of quarterly Company 
updates; and shareholders.

The Directors believe that the employees of the Company 
are one of its most important assets and the continued and 
sustained development of the Company relies on its ability to 
retain and attract employees of a high standard. Corero is 
proud to have over one-third of its employees with more than 
five years’ service.

The Corero equal opportunities policy ensures that all job 
applicants and employees are treated fairly and without 
favour or prejudice. We are committed to applying this policy 
throughout all areas of employment, recruitment and 
selection, training, development and promotion.

Employees are regularly informed of matters concerning their 
interest and the financial factors affecting the Company. The 
Company uses company-wide forums to communicate matters 
as well as team and individual meetings.

Corero is committed to promoting sustainability. We aim to 
follow and to promote good sustainability practice, to carry 
out our operations in a way which manages and minimises any 
adverse environmental impacts from our activities.

Corero encourages the reuse or recycling of office waste, 
including paper, packaging, computer supplies and redundant 
equipment. Wherever possible Corero ensures that waste 
materials are disposed of in an environmentally safe manner 
and in accordance with regulations. 

The Company operates a risk assessment process, which is 
embedded in day-to-day management and governance 
processes. As part of the annual planning and budgeting 
process, Corero management document 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 Board reviews the annual risk assessment including an 
annual assessment of the effectiveness of the Company’s 
internal control system, comprising financial, operational 
and compliance controls, to ensure that the Company’s risk 
management framework identifies and addresses all relevant 
risks in order to execute and deliver the Company’s strategy. 

The Directors are responsible for the Company’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 Company’s system of internal 
control is designed to manage, rather than eliminate, the risk 
of failure to achieve the Company’s business objectives and 
can only provide reasonable, and not absolute, assurance 
against material misstatement or loss.

The Company 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, and 
forecasts to the Board. 

The Audit, Risk and Compliance Committee (“ARCC”) reviews the 
effectiveness of internal controls. The ARCC 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 for consideration. The auditors report, assessment 
of the effectiveness of the internal control system and key 
judgements report for the Annual Report and Accounts for the 
year ended 31 December 2017 were tabled and reviewed by the 
ARCC during the year ended 31 December 2018, as well the 
Corero Risk Register and Stakeholder Analysis. 

Given the size of the Company, the Board has concluded it is 
not appropriate to establish a separate, independent internal 
audit function. The Board will keep this under review.

One third of all Directors are subject to annual reappointment 
by shareholders as well as any Director appointed to the Board in 
the period since the last AGM, any Non-Executive Director whose 
tenure is more than nine years or whose independence is the

will be offering themselves for re-election at the forthcoming 
AGM, as well as Peter George who was appointed since the 
Company’s last AGM.

The Board meets on average once a quarter; additional meetings 
or conference calls are held as required. 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.

34

The Company maintains liability insurance for its Directors 
and Officers. The Company has also entered into indemnity 
agreements with the Directors, in terms of which the Company 
has indemnified its Directors, subject to the Companies Act 
limitations, against any liability arising out of the exercise of 
the Directors’ powers, duties and responsibilities as a Director 
or Officer.

In the year ended 31 December 2018, the Board met on four 
scheduled occasions; further meetings and conference calls were 
held as and when necessary (with five additional such meetings

EVALUATE BOARD 
PERFORMANCE BASED 
ON CLEAR AND RELEVANT 
OBJECTIVES, SEEKING 
CONTINUOUS IMPROVEMENT

The Board is satisfied that, between the Directors, it has an 
effective and appropriate balance of skills and experience, 
including operational, commercial and technology expertise 
and experience. All members of the Board have at least 15 
years’ technology experience through investing in and working 
for a range of companies from start-ups to large established 
technology companies, with complementary financial, 
commercial, sales and marketing skills. 

All Directors are able to take independent legal advice in 
relation to their duties, if necessary at the Company’s expense. 
In addition, the Directors have direct access to the advice and 
services of the Company Secretary and Chief Financial Officer. 
The Directors keep their skills up to date through a 
combination of their other roles (if applicable), attending 
appropriate training courses and seminars funded by the 
Company if appropriate, and by reading widely. 

Corero’s Chairman, Jens Montanana, is a material shareholder 
with an equity interest in Corero of 38.4% at 9 April 2019, and 
is the Company’s largest shareholder. His interests are 
strongly aligned with all shareholders.

The Corero Board members biographies and their relevant 
experience, capabilities and skills and are set out on pages 28 
and 29.

There are no external advisers to the Board or any of its 
committees, other than the auditors (BDO LLP).

It has not been deemed necessary to formalise a training and 
development programme for each Director.

Corero has established a Board effectiveness review to enable 
the Board to stand back and assess its strengths and areas for 
development. This review will be conducted internally and will 
be performed annually. The first such review was conducted in 
January 2019. The review showed that the Board is operating 
effectively. The recommendations following this review were:

•  Annual away-day strategy review to be held.

•  Chairman to meet with each Director annually to undertake 

a formal review of each individuals’ performance, 
development plans and performance of the Board and 
committees.

The Board plans to refresh the performance assessment 
process based on external advice and if appropriate engage a 
third-party facilitator to assist in the performance of such 
effectiveness reviews every three years. 

Given Corero’s size, the Company does not have internal 
succession candidates for the Executive Directors. In the event 
an Executive Director replacement is required, the Company 
would seek to recruit a replacement through a recruitment 
search process. The Board are satisfied that the Company’s 
middle management will ensure the Company’s business is not 
adversely impacted in the period between an Executive 
Director leaving and a replacement being recruited.

The Corero NRC reviews and recommends nominees as new 
Directors to the Board. Senior management appointments are 
required to be approved by the Corero NRC.

The performance of the Executive Directors is measured 
against the internal budget with a performance related bonus 
for exceeding the internal budget targets.

The members of the NRC do not have any conflicts from 
cross-directorships that relate to the business of the 
committee. The members of the NRC do not have any 
day-to-day involvement in the running of the Group.

The NRC’s remit is to measure the performance of and 
determine the remuneration policy relating to Directors and 
senior employees. To support this responsibility, it has access 
to professional and other advice external to the Group. Taking 
the performance factors into account, it then makes 
recommendations to the Board.

Corero Network Security plc Annual Report and Accounts 2018#8

PROMOTE A CORPORATE 
CULTURE THAT IS BASED 
ON ETHICAL VALUES AND 
BEHAVIOURS

Corero recognises the importance of culture and values 
and in conjunction with employees defined the Company’s 
agreed values:

•  Integrity

•  Customer delight

•  Innovation

•  Open and honest communications

•  Empowerment

Corero has invested in an online tool, known as Kudos, which 
is being used to acknowledge, reinforce and measure the 
values-supporting behaviours and actions taken by team 
members.

The Corero equal opportunity policy sets out the Company’s 
position on equal opportunity in all aspects of employment. 
The policy has been developed to maintain the following 
policy objectives:

•  To provide a safe and welcoming environment, in which 

individuals are valued, included and respected;

•  To eliminate unfair discrimination;

•  To advance equality of opportunity; and

•  To foster good relations between different groups of people.

To assist the work of the NRC, the views of the Chief Executive 
Officer and Chief Financial Officer are also invited where 
appropriate. However, they do not participate in any decision 
related to their own remuneration.

The Group is committed to the governing objective of 
maximising shareholder value over time. Each year the 
remuneration framework and the packages of the Directors 
are reviewed to ensure they continue to achieve this objective.

The Group operates in the cyber security market which is a 
market with significant growth potential. It is also a 
competitive market with a number of players who are 
significantly larger than Corero. The Group’s executive 
Director remuneration policy is designed to attract and retain 
Directors of the calibre required to maintain the Group’s 
position in its marketplace. This is maintained through the use 
of bonus and share option schemes, as follows:

Bonus
A cash bonus designed to incentivise specific short-term 
financial goals. Goals and objectives are set for the executive 
Directors with a significant weight being put on meeting and 
exceeding key financial performance metrics. Executive 
Directors’ bonuses are set at two-thirds of base salary.

Share options
Share options are granted to encourage and reward delivery 
of the Company’s long-term strategic objectives and provide 
alignment with shareholders through the use of share-based 
incentives. 

All share-based incentives offered to Directors have a 3-year 
vesting schedule, with one-third vesting on the first 
anniversary of the grant/start date, a further third on the 
second anniversary of the grant/start date and the final third 
the third anniversary of the grant/start date. Shares acquired 
on the exercise of options may not be sold until the second 
anniversary of the grant date. Share options are granted with 
an exercise price set at the higher of market price or such 
other price as determined by the NRC.

customer delight.

The Board
The Board sets Corero’s overall strategic direction, reviews 
management performance and ensures that the Company has 
the necessary financial and human resource in place to meet 
its objectives. The Board is satisfied that the necessary 
controls and resources exist within the Company to enable 
these responsibilities to be met.

Audit, Risk and Compliance Committee 
(“ARCC”)
The ARCC has responsibility for planning and reviewing the 
Group’s interim and preliminary reports and accounts.

The ARCC determines the application of the financial reporting 
and internal control and risk management procedures and the 
scope, quality and results of the external audit.

Nominations and Remuneration Committee 
(“NRC”)
The remuneration committee is responsible for the policy 
for the remuneration of the executive Directors and senior 
management.

The NRC reviews and recommends nominees as new Directors 
to the Board and reviews the performance of the Executive 
Directors and sets the remuneration of the Executive 
Directors. In addition, the NRC determines the payment of 
bonuses to Executive Directors and approves the Company’s 
bonus and incentive arrangements for employees. 

Evolution of the Company’s governance 
framework 
The Board will on an on-going basis, and as the Company’s 
business develops and grows, review the appropriateness of 
the governance framework, including the composition of the 
Board and the requirement for an internal audit function, to

DIRECTORS’ REPORT

Group results
The Group’s Statement of Comprehensive 
Income on page 48 shows a loss for the  
year of $5.2 million (2017: restated loss 
$8.4 million).

Going concern
The financial position and cash flows are 
described in the Financial Review on pages 
25 to 27. An indication of likely future 
developments affecting the Company is 
included in the Strategic Report on pages 
8 to 27.

The Directors are, based on detailed 
financial projections, of the opinion that the 
Group and Company 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. 
The financial projections take into account 
the operational progress made by the 
Company over the past year and future 
opportunities as described in the Chief 
Executive Strategic Update on pages 8 to 15, 
and the Group’s Strategy as detailed on 
page 22 which is focused on scaling the 
business towards profitability. 

On this basis, the Directors have therefore 
concluded that it is appropriate to prepare 
the financial statements on a going concern 
basis. The financial statements do not 
include the adjustments that would result 
if the Group and Company was unable to 
continue as a going concern. Further details 
are included within notes 2 and 3 to the 
financial statements.

However, the ability of the Company and 
Group to achieve the future profit and cash 
flow projections cannot be predicted with 
certainty. Failure of the Company and the 
Group to meet these projections and deliver 
revenue growth may adversely impact the 
achievability of the bank loan covenants 
which may result in the bank loan being 
required to be repaid before the maturity 
date if the revenue covenants are not met 
and cannot be renegotiated. This would 
adversely impact the Company and the 
Group’s working capital position and would 
require the Company to raise additional 
funding, with no guarantee such funding 
would be secured. Taken together, the 
achievability of the projections and 
availability of additional funding if required 
indicate a material uncertainty that may 
cast significant doubt on the Company and 
the Group’s ability to continue as a going 
concern for the foreseeable future.

Dividends
The Directors have not recommended a 
dividend (2017: $nil).

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 20 to the 
financial statements. 

As at the date of this report, 401,995,161 
ordinary shares of 1p each (“ordinary 
shares”) were in issue and fully paid with an 
aggregate nominal value of $5.7 million.

Substantial shareholdings

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

•  Liquidity risk – arises from the Group’s 
management of working capital and 
finance charges. It is a risk that the Group 
will encounter difficulty in meeting its 
financial obligations, including a 
repayment term bank loan drawn down 
by the Company in May 2018 ($3.6m at 31 
December 2018) details of which are set 
out in note 16, as they fall due. Liquidity 
risk is managed by the finance function. 
Annual budgets are agreed by the Board, 
enabling the Group’s cash flow 
requirements to be anticipated.

•  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 seeks 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 14).

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

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.

•  Cash flow interest rate risk – the Group’s 
policy is to as far as possible minimise 
interest rate cash flow risk exposure on its 
financing. The Group is exposed to 
interest rate increases on the term bank 
loan ($3.6 million at 31 December 2018) 
details of which are set out in note 16, 
which bears interest at 3-month GBP Libor 
plus 7.5%. The bank loan does not have 
early repayment penalties and thus the 
Group can if GBP interest rates increase to 
punitive levels, seek to refinance the loan. 
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 was no material 

impact from trading currency risk on the 
Group’s profit or loss for the year 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. Exchange rate risks do 
arise in relation to (i) the bank loan which 
is GBP denominated and equity fund 
raises which are in GBP, given the 
Company’s AIM listing, to the extent such 
funds are required to support US dollar 
denominated funding requirements, and 
(ii) GBP denominated obligations of the 
Group given the invoicing currency of the 
Group is US dollar denominated. The 
Group has not hedged such GBP debt and 
equity fund raises or GBP denominated 
expenses in the past as US denominated 
funds received by the Group’s UK 
subsidiary have been used to fund the 
Group’s US subsidiary to the extent such 
funding has been required, with the GBP 
funding requirements satisfied from the 
GBP denominated funds generated from 
GBP debt and equity fund raises. The 
Group keeps this policy under review 
based on the expected timing of US 
dollar and GBP operational funding 
requirements.

The principal risk which applies to the 
parent Company’s financial statements  
is the risk that the returns generated by the 
subsidiaries might not support the carrying 
value of the cost of the investments in 
subsidiaries. The carrying value is tested at 
least annually for impairment and, if 
necessary, impaired.

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 $1.7 million (2017: $2.2 million) 
was made during the year. Amortisation of 
$2.9 million (2017: $2.4 million) and costs not 
capitalised of $0.9 million (2017: £1.5 million) 
were 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 Company’s progress. 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 plans to provide incentives 
for achievements which add value to 
the business.

Annual General Meeting
The AGM will be held at 68 Lombard Street, 
London, EC3V 9LJ on 21 May 2019 at 11.00 
a.m. The notice convening the meeting is  
on page 85 together with details of the 
business to be considered. 

DIRECTORS’ REPORT CONTINUED

Capital management
The Group monitors its available capital, 
which it considers to be all components of 
equity 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 Company may return capital 
to shareholders, issue new shares, or sell 
assets. The Group does not review its 
capital requirements according to any 
specified targets or ratios.

Treasury management
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 Financial Controller who 
reports to the Board on the implementation 
of Group treasury policy.

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. The 
Group complies with local WEEE regulations. 
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.”

Corero Network Security plc Annual Report and Accounts 2018STATEMENT OF DIRECTORS’ RESPONSIBILITIES

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.

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 
financial statements in accordance with 
International Financial Reporting Standards 
as adopted by the European Union (“IFRSs”). 
The Directors have chosen to prepare the 
Company financial statements in 
accordance with FRS101. 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 they have been prepared in 
accordance with IFRSs as adopted by the 
European Union, subject to any material 
departures disclosed and explained in the 
financial statements; and

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

to the members of Corero Network Security plc

Opinion
We have audited the financial statements of Corero Network Security plc (the ‘Parent Company’) and its subsidiaries (the ‘Group’) for the 
year ended 31 December 2018 which comprise the consolidated statement of comprehensive income, the consolidated and company 
statements of financial position, the consolidated statement of cash flows, the consolidated and company statements of changes in 
equity and the notes to the financial statements, including a summary of significant accounting policies. 

The financial reporting framework that has been applied in the preparation of the Group financial statements is applicable law and 
International Financial Reporting Standards (IFRSs) as adopted by the European Union. The financial reporting framework that has been 
applied in the preparation of the Parent Company financial statements is applicable law and United Kingdom Accounting Standards, 
including Financial Reporting Standard 101 Reduced Disclosure Framework (United Kingdom Generally Accepted Accounting Practice).

In our opinion:
•  the financial statements give a true and fair view of the state of the Group’s and of the Parent Company’s affairs as at 31 December 2018 

and of the Group’s loss for the year then ended;

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

•  the Parent Company financial statements have been properly prepared in accordance with United Kingdom Generally Accepted 

Accounting Practice; and

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

Basis for opinion
We conducted our audit in accordance with International Standards on Auditing (UK) (ISAs (UK)) and applicable law. Our responsibilities 
under those standards are further described in the Auditor’s responsibilities for the audit of the financial statements section of our 
report. We are independent of the Group and the Parent Company in accordance with the ethical requirements that are relevant to our 
audit of the financial statements in the UK, including the FRC’s Ethical Standard as applied to listed entities, and we have fulfilled our 
other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient 
and appropriate to provide a basis for our opinion.

Material uncertainty related to going concern
We draw attention to note 2.2 to the financial statements which states that the ability of the Group and Parent Company to continue as a 
going concern is reliant on the continued availability of its bank loan, the terms of which require compliance with certain covenants. Failure 
to achieve revenue and cashflow projections may adversely impact the achievability of the bank loan covenants which could result in the 
bank calling in the loan. This would require the Company to raise additional funding, with no guarantee such funding would be secured. 

These events and conditions indicate a material uncertainty exists that may cast significant doubt on the Group and Parent Company’s 
ability to continue as a going concern. Our opinion is not modified in respect of this matter. 

Given the conditions and uncertainties noted above, we considered going concern to be a key audit matter. We have performed the 
following work as part of our audit:

•  we reviewed the bank loan documents to understand the terms and covenants which the Group and Parent Company is required to 

comply with, comparing these to the Group’s forecasts;

•  we recalculated management’s covenant compliance calculations for the period under audit using the Directors’ forecasts for a period of  
at least 12 months from the date of approval of the financial statements, and compared them to the covenants in place for each period;

•  we obtained confirmations from the lending bank in relation to covenant requirements and compliance during 2018; and 

•  we challenged the forecasts and sensitivity analysis used by the Director's to assess the Group’s and Parent Company’s ability to meet 

its financial obligations as they fall due for a period of at least 12 months from the date of approval of the financial statements, by 
examining post year end order values compared to forecast financial information and by comparing previous forecast financial 
performance to subsequent actual results.

Key audit matters
In addition to the matter described in the material uncertainty related to going concern section above, key audit matters are those 
matters that, in our professional judgement, were of most significance in our audit of the financial statements of the current period and 
include the most significant assessed risks of material misstatement (whether or not due to fraud) that we identified including those 
which had the greatest effect on the overall audit strategy, the allocation of resources in the audit, and directing the efforts of the 
engagement team. These matters were addressed in the context of our audit of the financial statements as a whole, and in forming  
our opinion thereon, and we do not provide a separate opinion on these matters. 

44

Corero Network Security plc Annual Report and Accounts 2018Key Audit Matter

Revenue recognition 

See accounting policy at note 2.5, the key accounting 
estimate at note 3.2 and note 4.

The Group generates revenue primarily from the sale  
of hardware and associated software and related 
maintenance and support contracts. It does this directly 
through arrangements with end-users (either through 
the sale of hardware and a software licence or by selling 
the software as a service) as well as to distributors. 
The sales of licences may be on a perpetual or a fixed 
term basis. 

We considered there to be a significant audit risk arising 
from the allocation of the value of the transaction 
between the multiple elements or deliverables included 
in the sale as well as the timing of revenue recognition 
with regard to proper deferral of support revenues and 
cut off around the year end. 

Management also undertook an exercise prior to 2018 to 
evaluate the impact of IFRS 15 Revenue from Contracts 
with Customers on its financial statements. This is a 
complex development in IFRS which we considered to be 
part of the revenue recognition risk in the current year. 

Goodwill and intangible asset impairment

See accounting policy at note 2.12 and note 8. 

In accordance with IAS 36, goodwill is tested for 
impairment annually and other non-current tangible 
assets with finite lives are tested for impairment 
whenever an indicator of impairment arises. 

Management performed an impairment review over 
its sole cash generating unit (CGU) – Corero Network 
Security (CNS) – as at 31 December 2018 using a 
discounted cash flow model to calculate fair value less 
costs to sell. The impairment review necessitates 
significant management judgement over the timing and 
degree of certainty attaching to forecast net cash flows 
and the rate at which those future cash flows should be 
discounted to present value. Certain key assumptions 
and data points are required to be disclosed along with 
sensitivity calculations where reasonably possible 
changes in key assumptions could give rise to an 
impairment. The accurate disclosure of such information 
formed part of the risk we assessed as being present.

The recoverable amount of the Group’s CNS CGU was 
assessed as being higher than its carrying value at the 
reporting date and therefore, management concluded 
that the goodwill and intangible assets were not 
impaired at the reporting date.

How we addressed the matter in our audit

Our audit procedures included assessing the appropriateness of the revenue 
recognition policy in accordance with IFRS 15 and the work undertaken by 
management on the transition to that new accounting standard. 

We gained an understanding of the detail of the Group’s methodology in 
determining the fair value of the different deliverables in multiple element 
arrangements as set out in note 2.5 and examined management’s approach 
to fair value measurement, to ensure it provided a suitable basis on which to 
recognise revenues. 

We selected a sample of contracts for testing covering the Group’s different 
sales models. We assessed whether the revenue recognised was calculated in 
accordance with the Group’s accounting policy and in the correct period. 

We also tested the accuracy of the deferred income balance, which arises 
most commonly on deferred maintenance and support income, and tested a 
sample of transactions around the year end to ensure that they were 
recorded in the correct period.

Our work on the impairment review prepared by management had a dual 
focus: firstly, to ensure the model was mechanically accurate and prepared in 
accordance with the detailed requirements of IAS36 and secondly, to ensure 
that the assumptions regarding future cash flows and the rate at which they 
had been discounted were appropriate to the Group’s circumstances. 

We used valuations and tax specialists in order to assist with our 
interrogation of the model and to support our assessment of the treatment 
of future tax savings arising from available losses. This work also included 
comparison to industry data, historic trading, and macro-economic factors. 

Our audit procedures relating to the review of operating cash flows included 
verification of the existence of selected post year end sales and company 
internal sales initiatives which are expected to drive growth in 2019, as well  
as a comparison of previous performance to expectations. 

We took into account previous shortfalls against sales targets and discussed 
key sensitivities with those charged with governance. Fundamental to this 
evaluation was a comparison of the forecasts in the impairment review to 
recent financial performance and budgets approved by the Board, verifying 
that the sensitivities prepared by management were sufficiently challenging. 

We examined development cost intangible assets and property, plant and 
equipment to determine that no additional impairment indicators in respect 
of specific assets within the CGU were present.

We also considered the appropriateness of the disclosures made in notes 2.12, 
12 and 8 to the financial statements, ensuring these were balanced in terms 
of content, factually and arithmetically accurate and included all information 
required under IAS 36 Impairment of Assets.

Notice of AGMCorporate DirectoryOverviewStrategic ReportGovernanceFinancial StatementsINDEPENDENT AUDITOR’S REPORT CONTINUED
to the members of Corero Network Security plc

Our application of materiality
We apply the concept of materiality both in planning and performing our audit, and in evaluating the effect of misstatements. For planning, 
we consider materiality to be the magnitude by which misstatements, including omissions, could influence the economic decisions of 
reasonable users that are taken on the basis of the financial statements. In order to reduce to an appropriately low level the probability that 
any misstatements exceed materiality, we use a lower materiality level, performance materiality, to determine the extent of testing needed. 
Misstatements below these levels will not necessarily be evaluated as immaterial as we also take account of the nature of identified 
misstatements, and the particular circumstances of their occurrence, when evaluating their effect on the financial statements as a whole.

Level of materiality applied and rationale
Having re-examined the basis for setting materiality, we considered that using aggregate operating expenses and cost of sales as a benchmark 
is, at the current time, the most appropriate measure for assessing the Group’s scale of operations and level of activity. In the prior year, we 
referred to the EDITDA loss as our materiality benchmark. As the Group expects to move towards profitability, continuing to use EBITDA loss 
would in time have led to our materiality level becoming disproportionate to the scale of the Group’s activities. Using this benchmark, we set 
materiality at $297,000, being 2% of aggregate operating expenses and cost of sales (2017: $291,000, being 5% of EBITDA). 

Materiality in respect of the audit of the Parent Company has been set at $148,500 (2017: $145,000) based on 50% of Group materiality. 

Performance materiality was set at 75% of materiality for both the Group and Parent Company audits. In setting the level of performance 
materiality we considered a number of factors including the expected total value of known and likely misstatements (based on past 
experience and other factors) and management’s attitude towards proposed adjustments.

Component materiality
We set materiality for the Corero Network Security, Inc. component of the Group based on 80% (2017: 90%) of Group materiality as it makes up 
the majority of the Group’s external revenue generating activities. UK components were audited to a lower materiality of between 5% and 25% 
(2017: between 10% and 50%) of Group materiality. In the audit of each component, we further applied a performance materiality level of 75% 
of the component materiality level to our testing to ensure that the risk of errors exceeding component materiality was appropriately mitigated.

Agreement with the Audit Committee
We agreed with the Audit Committee that we would report to the Committee all Group audit differences individually in excess of $14,850 
(2017: $13,000) and, in our audit of the Parent Company, those in excess of $7,500 (2017: $7,250). We also agreed to report differences 
below this threshold that, in our view, warranted reporting on qualitative grounds.

An overview of the scope of our audit
Our Group audit was scoped by obtaining an understanding of the Group and its environment, including the Group’s system of internal 
control, and assessing the risks of material misstatement in the financial statements at the Group level. 

We obtained an understanding of the entity-level controls of the Group as a whole which assisted us in identifying and assessing risks of 
material misstatement due to fraud or error, as well as assisting us in determining the most appropriate audit strategy.

A full scope audit was performed for each component included in the consolidation. All audit work was undertaken by the Group audit team. 

Other information
The Directors are responsible for the other information. The other information comprises the information included in the Annual Report 
and Accounts other than the financial statements and our auditor’s report thereon. Our opinion on the financial statements does not 
cover the other information and, except to the extent otherwise explicitly stated in our report, we do not express any form of assurance 
conclusion thereon.

In connection with our audit of the financial statements, our responsibility is to read the other information and, in doing so, consider 
whether the other information is materially inconsistent with the financial statements or our knowledge obtained in the audit or 
otherwise appears to be materially misstated. If we identify such material inconsistencies or apparent material misstatements, we are 
required to determine whether there is a material misstatement in the financial statements or a material misstatement of the other 
information. If, based on the work we have performed, we conclude that there is a material misstatement of this other information,  
we are required to report that fact. We have nothing to report in this regard.

Opinions on other matters prescribed by the Companies Act 2006
In our opinion, based on the work undertaken in the course of the audit:

•  the information given in the strategic report and the Directors’ report for the financial year for which the financial statements are 

prepared is consistent with the financial statements; and

•  the strategic report and the Directors’ report have been prepared in accordance with applicable legal requirements.

46

Corero Network Security plc Annual Report and Accounts 2018Matters on which we are required to report by exception
In the light of the knowledge and understanding of the Group and the Parent Company and its environment obtained in the course of the 
audit, we have not identified material misstatements in the strategic report or the Directors’ report.

We have nothing to report in respect of the following matters in relation to which the Companies Act 2006 requires us to report to you if, 
in our opinion:

•  adequate accounting records have not been kept by the Parent Company or returns adequate for our audit have not been received from 

branches not visited by us; or

•  the Parent Company financial statements are not in agreement with the accounting records and returns; or

•  certain disclosures of Directors’ remuneration specified by law are not made; or 

•  we have not received all the information and explanations we require for our audit.

Responsibilities of Directors
As explained more fully in the Directors’ responsibilities statement set out on page 43, the Directors are responsible for the preparation of 
the financial statements and for being satisfied that they give a true and fair view, and for such internal control as the Directors determine is 
necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error.

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

Auditor’s responsibilities for the audit of the financial statements
Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material 
misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high 
level of assurance, but is not a guarantee that an audit conducted in accordance with ISAs (UK) will always detect a material misstatement 
when it exists.

Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be 
expected to influence the economic decisions of users taken on the basis of these financial statements.

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

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

Notice of AGMCorporate DirectoryOverviewStrategic ReportGovernanceFinancial StatementsNOTES TO THE FINANCIAL STATEMENTS

1. General information
Presentation currency
These consolidated financial statements are presented in US dollars (“$”) which represents the presentation currency of the Group. 

The average $-GBP sterling (“GBP”) exchange rate, used for the conversion of the Statement of Comprehensive Income, for the 12 months 
ended 31 December 2018 was 1.33 (2017: 1.29). The closing $-GBP exchange rate, used for the conversion of the Group’s assets and 
liabilities, at 31 December 2018 was 1.28 (2017: 1.35). 

Corero Network Security plc is a public limited company incorporated in the United Kingdom under the Companies Act 2006 and 
registered in England and Wales. The functional currency of the Company is GBP.

2. Significant accounting policies
2.1 Basis of preparation
The Group 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. The parent Company financial statements have been prepared in accordance with FRS 101 
(Financial Reporting Standard 101) ‘Reduced Disclosure Framework’. 

New Standards impacting the Group that have been adopted in the annual financial statements for the year ended 31 December 2018, 
and which give rise to a change in the Group’s accounting policies are:

•  IFRS 9 Financial Instruments; and 

•  IFRS 15 Revenue from Contracts with Customers.

2.2 Going Concern
The financial statements have been prepared on a going concern basis. 

The Directors have prepared detailed income statement, balance sheet and cash flow projections for the period to 31 December 2020. 
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 and Company will maintain a positive cash balance until at least December 2020. In addition, the 
projections and sensitivity analyses confirm that the bank loan covenants will be met for a period of at least 12 months from the date of 
approval of these financial statements. 

On this basis, the Directors have therefore concluded that it is appropriate to prepare the financial statements on a going concern basis. 

However, the ability of the Company and Group to achieve the future profit and cash flow projections cannot be predicted with certainty. 
Failure of the Company and the Group to meet these projections and deliver revenue growth may adversely impact the achievability of 
the bank loan covenants which may result in the bank loan being required to be repaid before the maturity date if the revenue covenants 
are not met and cannot be renegotiated. This would adversely impact the Company and the Group’s working capital position and would 
require the Company to raise additional funding, with no guarantee such funding would be secured. 

Taken together, the achievability of the projections and availability of additional funding if required indicate a material uncertainty that 
may cast significant doubt on the Company and the Group’s ability to continue as a going concern for the foreseeable future.

The financial statements do not include the adjustments that would result if the Group and Company was unable to continue as a 
going concern.

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 2018. 

Subsidiaries are entities controlled by the Group. Control is deemed to exist when the Group has all of the following elements: a) power 
over the subsidiary, b) exposure or rights to variable returns from that subsidiary, c) ability to use its power to affect the amount of the 
return from the subsidiary. 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.

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.

Intra-group balances and transactions are eliminated on consolidation.

54

Corero Network Security plc Annual Report and Accounts 2018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 
acquisition, 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.

2.5 Revenue
The Group’s revenue is derived from the following products and services:

•  Hardware and perpetual software licenses;

•  Support services for a defined term;

•  Installation and training services;

•  DDoS protection as-a-service (“DDPaaS”) for a defined term;

•  SecureWatch Managed Service (enhanced security monitoring services) for a defined term; and

•  Software subscription licenses for a defined term.

The element of DDPaaS revenues pertaining to the lease of as-a-service assets is included in reported revenues and is recognised on a 
straight line basis over the term of the contract.

Performance obligations, timing of revenue recognition and revenue recognition

Revenue is recognised when control of the goods (hardware and software) transfer to the customer and services are delivered. Goods are 
shipped free on board (“FOB”) from Corero, or Corero’s contract manufacturer, to the customer. The point of transfer of control for 
hardware is at the point of FOB shipment to the customer and for software at the point of electronic transfer to the customer.

Revenue recognised on transfer of control of hardware and  
software products

Hardware, perpetual software licenses and software 
subscription licenses

Revenue recognised over-time (over the term of the contract)

Support, DDPaaS and SecureWatch Managed services

Revenue recognised once the service has been delivered

Installation and training services

Determining the transaction price

The contract price is determined by reference to the Corero Sales Quotation or DDPaaS Agreement and is a fixed price. Certain DDPaaS 
contracts have an element of the transaction value or all of the transaction value determined by reference to a share of the customers’ 
revenue generated from the Corero solution (“Revenue Share”). This Revenue Share revenue is recognised when the Revenue Share is 
determined or can be reasonably estimated.

Corero does not have any other variable consideration payable by the customer and does not pay any consideration to the customer. 
There is no provision for purchase price adjustments, right of return or price concessions.

Allocating amounts to performance obligations

For contracts containing only a single performance obligation (annual support services, DDPaaS and SecureWatch Managed Service) 
there is no requirement to make an allocation of the contract price. For contracts containing multiple products, the transaction price is 
allocated to the separate performance obligations based on relative stand-alone selling prices (“SSP”). SSP equates to the historic best 
estimated selling price methodology previously applied consistently by Corero in prior year financial statements. The SSP is determined 
using defined price lists and historic customer discount rates. 

55

Notice of AGMCorporate DirectoryOverviewStrategic ReportGovernanceFinancial Statements2. Significant accounting policies continued
Incremental costs of obtaining a contract

Sales commission paid to Corero sales employees is an incremental cost of obtaining a contract. Sales commission relating to the support 
revenue from a new sales contract is recorded in prepayments and amortised over five years. Corero has considered the requirements of 
the IFRS15 standard with regards to the amortisation period which requires amortisation on a systematic basis that is consistent with the 
transfer to the customer of the goods or services to which the asset relates. The expectation, supported by historic evidence, is that 
customers will generally renew their support contracts for more than three years with the additional expectation of follow-on hardware 
and software (and associated services) business from a significant number of existing customers. Based on this, Corero has assessed that 
a reasonable period for capitalised sales commission to be amortised is five years. Periodic customer reviews will be undertaken to 
ascertain if there is any evidence that the value of the customer relationship has been negatively impacted, in which case the prepayment 
will be appropriately written down. Applying the practical expedient, Corero recognises the incremental costs of obtaining contracts as 
an expense when incurred if the amortisation period of the prepayment that Corero otherwise would have recognised is one year or less.

Fulfilment costs

Corero’s principal fulfilment costs relate to the costs of the Corero customer support team which delivers the customer support services, 
DDPaaS services and the SecureWatch Managed services. These costs are not separately allocated or identifiable against specific 
customers. Therefore, these costs are recognised in the period in which they are incurred.

The Group chose to adopt IFRS15 on a fully retrospective basis. After reviewing the requirements of IFRS15, Corero has concluded that no 
restatement to previously recognised revenue was required and there was no requirement to amend existing contract liabilities. None of 
the practical expedients relating to contracts with customers were therefore required to be applied.

The impact of adopting IFRS15 on a fully retrospective basis for the capitalisation and amortisation of sales commission was to reduce the 
operating expenditure/loss for the relevant reporting periods and increase trade and other receivables (prepayments). The capitalised 
sales commission balance at 31 December 2018 was $211,000 (2017: $164,000). The amortisation of sales commission was $50,000 in the 
12 months ended 31 December 2018 (2017: $21,000). 

Contract assets and liabilities

Contract assets arise when goods and services have been delivered and invoiced but payment is not yet due. Contract liabilities arise for 
future delivery of services which have been invoiced and payment is due. Contract liabilities are shown as deferred income in the 
Statement of Financial Position.

2.6 Government grants
Government grants are recognised at fair value when there is reasonable assurance that the Group will comply with the conditions 
attaching to them and the grant will be received. Grants related to purchase of assets are treated as deferred income and allocated to 
the Statement of Comprehensive Income over the useful lives of the related assets while grants related to expenses are netted off 
against the related item of expenditure in the Statement of Comprehensive Income – Profit and Loss. 

2.7 Cost of sales
Cost of sales includes all direct costs associated with revenue generation, including goods directly related to revenue, services delivery, 
operation costs, DDoS as-a-service depreciation and amounts charged by external third parties for services. Examples of such costs 
would include third party hardware costs and third party software license costs.

2.8 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 from GBP into US dollars at the 
exchange rate at the reporting date. Income and expense items are translated into US dollars at the average exchange rates for the 
period. The resulting exchange differences are recognised in the translation reserve.

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 – Profit and Loss.

After initial recognition, internally generated intangible assets are carried at cost less accumulated amortisation and any impairment 
losses. Amortisation is charged once the asset is capable of generating economic benefits. 

Acquired intangible assets

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 and customer relationships. 

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.

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 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.

2.10 Property, plant and equipment
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, evaluation assets and DDoS protection as-a-service assets – 3 years (straight line)

•  Fixtures and fittings – 5 years (straight line)

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. Evaluation assets are used by customers during 
proof of concept trials. Evaluation assets are stated at cost less accumulated depreciation. When an evaluation asset is retained by a 
customer as part of a sale, the net book value of the evaluation asset is charged to cost of sales. Depreciation of DDoS protection 
as-a-service assets is charged to cost of sales.

57

Notice of AGMCorporate DirectoryOverviewStrategic ReportGovernanceFinancial Statements2. Significant accounting policies continued
Subsequent costs are included in an asset 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 – Profit and Loss as incurred.

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 included in the Statement of Comprehensive Income – Profit and Loss.

2.11 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, the value of which may not be recoverable. 

To minimise this risk, the Group evaluates inventory levels and expected usage on a periodic basis and records valuation allowances as required.

2.12 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 ("CGU") to which the asset 
belongs is determined.

The recoverable amount of an asset or a CGU is the higher of its fair value less costs to sell and its value in use. The recoverable amount is 
calculated using the present value of the future cash flows expected to be derived from an asset or CGU. This present value is derived 
using a cost of capital 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 or CGU 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 – Profit and Loss.

Goodwill acquired in a business combination is, from the acquisition date, allocated to each of the CGU's or groups of CGU's 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 CGU's if the recoverable amount of the CGU is less than the carrying amount of the CGU. The 
impairment loss is allocated to reduce the carrying amount of the assets of the CGU by first reducing the carrying amount of any goodwill 
allocated to the CGU, and then reducing the carrying amounts of the other assets of the CGU pro rata.

If an impairment loss subsequently reverses, the carrying amount of the asset or CGU 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 – Profit and Loss. Impairment losses on 
goodwill are not subsequently reversed.

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 asset 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 – Profit and Loss 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.

58

NOTES TO THE FINANCIAL STATEMENTS CONTINUEDCorero Network Security plc Annual Report and Accounts 2018Corero Network Security plc Annual Report and Accounts 2018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 – Profit and Loss on a straight-line basis over the lease 
term. The aggregate benefit of lease incentives are recognised as a reduction of the rental expense over the lease term on a straight-line basis.

Amounts receivable under DDPaaS agreements in relation to as-a-service assets are recognised as revenue as explained in note 2.5.

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.

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 makes contributions in respect of certain employees to defined contribution pension plans under which it is required to pay 
fixed contributions to group and personal pension funds. 

Contributions to the schemes are based on a proportion of the employees’ earnings and are charged to the Statement of Comprehensive 
Income – Profit and Loss when incurred. The Group has no obligation 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 modified retrospective basis has been used for the application of IFRS 9.

59

Notice of AGMCorporate DirectoryOverviewStrategic ReportGovernanceFinancial Statements2. Significant accounting policies continued
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. The simplified approach is used for assessing the expected credit loss on trade receivables, requiring the lifetime 
expected credit loss to be recorded as the provision for impairment. 

An impairment provision is recorded against the loan note instrument between the Company and Corero Network Security, Inc based on 
calculating the risk adjusted carrying value of the loan to take account of the credit loss which is expected to arise over the period until 
the cash is realised. In situations where the loan amount is expected to be recovered, the expected credit loss is limited to the effect of 
discounting the loan over the period until repayment is realised at the effective interest rate. 

Cash and cash equivalents

Cash and cash equivalents include cash in hand and deposits on call with banks.

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.

Debt obligations

Debt obligations include interest bearing bank borrowings which are stated at their fair value at time of initial recognition.

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 costs.

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. If an 
option grant is cancelled the previously recorded expense is credited to the Statement of Comprehensive Income - Profit and Loss.

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

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 Standards and Interpretations not yet effective
There are a number of standards, amendments to standards, and interpretations which have been issued that are effective in future 
accounting periods that the Group has decided not to adopt early. The most significant of these is:

IFRS 16 – Leases. Effective for periods beginning on or after 1 January 2019.

The adoption of IFRS16 will result in the Group recognising right-of-use assets and lease liabilities for all contracts that are, or contain, a lease. 
For leases currently classified as operating leases, under current accounting requirements the Group does not recognise related assets or 
liabilities, and instead spreads the lease payments on a straight-line basis over the lease term, disclosing the total future commitment.

The Group will apply the modified retrospective adoption method under IFRS16, and, therefore will recognise leases on balance sheet as 
at 1 January 2019. In addition, the right-of-use assets measure will be determined by reference to the lease liability on that date. The 
Group will use the practical expedient not to recognise leases whose term ends within 12 months of the initial application (1 January 2019) 
and account for these leases as a short-term lease. For the Group’s one applicable lease at 31 December 2018, an office premises lease, it is 
anticipated a right-of-use asset and lease liability of approximately $76,000 will be recognised on 1 January 2019. Instead of recognising an 
operating expense for its applicable operating lease payments, the Group will recognise interest on its lease liabilities and amortisation 
on its right-of-use assets. For the applicable lease, the application of IFRS 16 will reduce the 2019 operating expenses by $31,000 and 
increase the interest charge by $3,000. 

The Group does not expect any other standards issued by the IASB, but not yet effective, to have a material impact on the Group.

NOTES TO THE FINANCIAL STATEMENTS CONTINUEDCorero Network Security plc Annual Report and Accounts 2018Corero Network Security plc Annual Report and Accounts 2018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 and a project has passed the 
feasibility phase, 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. Fair value less costs to sell 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 appropriate discount rates. 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 CGU are set out in note 8.

Impairment of investments (applies to the Company financial statements only)

The Directors have reviewed the cost of investments in subsidiaries of the Company with reference to current and future trading 
conditions. The investment in subsidiaries has been reviewed with reference to a valuation based on a discounted free cash flow, in 
conjunction with the goodwill impairment review, which the Directors consider to be an appropriate valuation methodology. 

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 contained in the projections is detailed in the note 2.2. 

Standalone Selling Price – Revenue recognition

On a quarterly basis the Group analyses the selling prices for each deal compared to the current Standalone Selling Price (“SSP”).  
This analysis includes grouping similar deals based on qualitative factors such as customer profile, size, and region, together with  
a quantitative comparison to the then current SSP. SSP fair value prices are adjusted for future quarters if management identifies  
a pattern of variances of greater than 10% between actual selling prices and the then current SSP. 

61

Business segments
The Group is managed according to one business unit, Corero Network Security, which makes up the Group’s reportable operating 
segment. This business unit forms 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.

Factors affecting future tax charges
As at 31 December 2018, the Group’s cumulative fixed asset timing differences were $394,000 (2017: $426,000) and no deferred tax asset 
has been recognised in respect of these items.

In addition, the tax losses at that date amounted to $85.4 million (2017: $82.0 million). This comprised UK tax losses of $12.1 million and US 
tax losses of $73.3 million. $9.0 million of the tax losses relate to pre-acquisition US tax losses which can be offset against taxable profits 
over 15 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 expire 20 years from the end of the accounting period in which the loss arose. UK 
tax losses do not expire.

Deferred tax assets of $2.0 million (2017: $2.1 million) relating to the UK tax losses (applying a tax rate of 17.0%) and the deferred tax 
assets of $15.5 million (2017: $14.6 million) relating to the US tax losses and taxable temporary fixed asset differences (applying a tax rate 
of 21.0%) have not been recognised due to uncertainties as to the extent and timing of their future recovery.

7. 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. The effects of anti-dilutive ordinary shares resulting from the exercise of share 
options are excluded from the calculation of the loss per share. 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 single CGU, Corero Network Security (“CNS”).

The recoverable amount for the CNS CGU was determined based on a discounted cash flow calculation to calculate fair values less costs 
to sell using cash flow projections over a 10 year period (2017: 10 year period). The discounted cash flow approach is a level 3 fair value 
calculation in the IFRS 13 fair value hierarchy. 

The key assumptions for the discounted cash flow 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 periods

Average annual revenue growth rates used for the forecast/extrapolated periods:

  Year 1–2 (forecast period)

  Years 3–5 (extrapolated period)

  Years 6–10 (extrapolated period)

Revenue growth rate used beyond the extrapolated period

The pre-tax cash flows for the forecast period are derived from the most recent financial budget for the year ending 31 December 2019 
and the plan for the year ending 31 December 2020 approved by the Board, with a downward revenue adjustment reflecting prior year 
experience (37.5% applied to the 2019 budget and 50% to the 2020 plan). The extrapolation for the period 2021 to 2028 is based on 
management estimates (with the key assumptions set out below).

The future pre-tax cash flows are discounted by a WACC of 14.4% (2017: 17.7%).

Notice of AGMCorporate DirectoryOverviewStrategic ReportGovernanceFinancial Statements8. Goodwill continued
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 2019 to 2023 (ii) and the discount rate. 

The cash flow forecasts assume a CAGR revenue growth of 26.2% in the period 2018 to 2023 (28.1% for the period 2018 to 2020) and 7.4% 
for the period 2023 to 2028 (a CAGR of 16.4% for 10-year forecast extrapolated period). These revenue growth rates reflect a downward 
revenue adjustment of 37.5% applied to the CNS 2019 budget revenues and 50% applied to the 2020 plan revenues (and a corresponding 
reduction of 18.75% in 2019 operating costs and capital expenditure, and 20% in 2020 operating costs and capital expenditure) reflecting 
prior year experience.

The management of the Group believe these growth rates are appropriate for the forecasts given the progress the business made in 
2018, the strategy for 2019 which is focused on scaling the business for profitability through a three-pronged go-to-market focus (direct 
sales, indirect channel sales, and go-to-market partner sales from partners such as Juniper) and the planned investment in sales and 
marketing. This strategy is expected to deliver a step change in revenue in the forecast period. 

The assumed growth rates are supported by the fact that the IT security market is forecast to grow strongly for the foreseeable future. 

•  The DDoS appliance market is expected to reach $1.45bn by 2022 (Source: IHS Markit technology research – DDoS Prevention 

Appliances Worldwide, Biannual Market Tracker H2 2018 (published 19 November 2018)) – a CAGR of 11.0% in the period 2017 to 2022. 

•  According to IDC (one of the leading global IT analyst firms), the global spending on security-related hardware, software and services is 

forecast to grow to $133.7bn in 2022 (a CAGR of 9.9% over the 2017-2022 forecast period). (Source: IDC Update to Worldwide Semi-
annual Security Spending Guide published 4 October 2018). 

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 2.5% is considered reasonable as historically IT spend 
has exceeded GDP growth.

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 2.68% (based on 10-year US government bonds) (2017: 2.48%), comparable company betas, an equity risk premium of 7.4% 
(2017: 7.4%), and small company risk premium of 4.5% (2017: 4.5%). The WACC has been assessed based on that fact that the Company 
had debt at 31 December 2018 of $3.8 million. 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 changes in cash flow forecasts and 
discount rate assumptions, and there is no guarantee that the expected growth will be achieved. If the discount rate is increased by 50%, 
which in the assessment of management is reasonably possible, from 14.4%% to 21.6%, this would result in a $1.2 million impairment of 
goodwill. If the downward revenue adjustment of 37.5% applied to the CNS 2019 Budget and 50% to the 2020 Plan revenues (and 
corresponding reduction of 18.75% in CNS Budget 2019 operating costs and capital expenditure, and 25% in the 2020 Plan operating 
costs and capital expenditure) was increased by 20%, which in the assessment of management is reasonably possible, this would result in 
a $6.6 million impairment of goodwill. 

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.

None of the Company’s trade and other receivables are secured by collateral or credit enhancements.

The Group applies the simplified approach to measuring expected credit losses using a lifetime expected credit loss for trade 
receivables and contract assets. To measure expected credit losses on a collective basis, trade receivables and contract assets are 
grouped based on a similar credit risk and aging. The expected loss rates are based on the Group’s historical credit losses experienced 
over a two year period prior to the period end. The historical loss rates are then adjusted for current and forward-looking information 
on macroeconomic factors affecting the Group’s customers. The Group has identified gross domestic product growth rates, 
unemployment rates and inflation rates as the key macroeconomic factors in the countries in which the Group operates. The 
calculated expected credit loss allowance for the current and prior reporting periods has not been included as an impairment 
provision as the Directors consider it to be immaterial. 

The Directors consider that the carrying amount of trade and other receivables approximates their fair value.

Notice of AGMCorporate DirectoryOverviewStrategic ReportGovernanceFinancial Statements24. Contingent liabilities
Corero Network Security (UK) Limited was in December 2015 awarded a grant of £600,000 for a development project over three years 
from Scottish Enterprise. Any monies becoming repayable by Corero Network Security (UK) Limited under the grant terms for breaches 
of the grant conditions are guaranteed by the Company. These conditions which are typical for a grant of this nature, and which apply for 
a period of five years from the final grant payment date (being 14 March 2019), include maintaining minimum headcount in Scotland and 
no change of control.

25. Share options
The Company has the following share option schemes:

•  Enterprise Management Incentive Scheme for its employees, which has been approved by HMRC

•  Executive Enterprise Management Incentive Scheme, which has been approved by HMRC

•  Unapproved Share Option Scheme

•  Deferred Payment Share Plan

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

All other options granted in the period 2010 to 2018 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. Shares acquired on the exercise of  
an option may not be sold until the expiry of the second anniversary following the date of option grant. With the exception of options 
granted in April 2017 to Directors and certain employee which include a revenue growth performance vesting condition, there are no 
vesting conditions for options granted.

If an option holder ceases to be in employment or hold office within the Group, options granted shall immediately lapse unless such 
cessation is because of the option holder’s death; the option holder’s ill health or disability; the company that employs the option holder 
ceasing to be under the control of the Company or such company ceasing to be within the Group; the transfer of sale of the undertaking 
or part-undertaking in which the option holder is employed to a person who is neither under the control of the Company nor within the 
Group; or any other reason that the Board in its absolute discretion shall determine.

On a cessation of employment or office as set out above, options shall be exercisable to the extent they have vested according to the 
terms of the option agreement and the provisions of the relevant share option scheme and must be exercised within 30 days following 
such cessation unless otherwise determined by the Board or if such cessation is by reason of death in which case the option holder’s 
personal representatives must exercise the option within 12 months following the date of the option holder’s death.

On 18 March 2014, the Enterprise Management Incentive Scheme was extended by 10 years to 20 April 2021.

The closing mid-market price for the Company’s shares at 31 December 2018 was 12.5p (16c) and the high and low for the year was 13.35p 
(17c) and 5.6p (8c). 

In the 12 months to 31 December 2018, 3,333 options were exercised and 4,328,417 options were forfeited.

On 9 June 2017, the Company announced the cancellation and re-granting of options over Ordinary Shares to certain Directors and 
employees, with an option re-grant price of 13.6p (“New Option Grant Price”) being the weighted average price of the Company’s historic 
investment rounds. A total of 6,667,055 options were granted on 8 June 2017 at the New Option Grant price in return for the cancellation 
of existing option grants. The new options have the same vesting, with no performance vesting conditions, and share sale conditions as 
the other share option grants.

The Company also announced on 9 April 2017 that it intended to cancel 2,356,000 options previously granted to Andrew Miller and 
425,000 options previously granted to Jens Montanana and grant an equal number of new options to each of them (the “New Concert 
Party Options”) at the New Option Grant Price. Andrew Miller and Jens Montanana are considered to be a “Concert party” under the City 
Code on Takeovers and Mergers. Since the terms of the New Concert Party Options were different from existing options currently held by 
Andrew Miller and Jens Montanana, the Company required consent from the Panel on Takeovers and Mergers (“Panel”) to waive the 
obligation on them to make a general offer to shareholders under Rule 9 of the Code that could otherwise arise if the New Concert Party 
Options were exercised. On 8 May 2018, 2,356,000 previously granted to Andrew Miller and 425,000 options previously granted to Jens 
Montanana were cancelled. On 9 May 2018, 2,356,000 options were granted to Andrew Miller and 425,000 options were granted to Jens 
Montanana at the New Option Grant Price. The new options have the same vesting, with no performance vesting conditions, and share 
sale conditions as the other share option grants. The Panel’s waiver was approved by independent shareholders, being shareholders other 
than Andrew Miller and Jens Montanana, at the 2018 Annual General Meeting.

The Nominations and Remuneration Committee (“NRC”) approves the grant of share options to employees of the Group under the 
Group’s share option schemes. 

Share options are granted with a fixed exercise price which is equal to the market price at the date of the grant or higher price 
determined by the NRC. The share options granted are required to be exercised within 10 years from the date of grant. 

Share options are valued using the Black-Scholes option-pricing model.

Corero Network Security plc Annual Report and Accounts 2018The following notes explain your general rights as a shareholder and your rights to attend and vote at the AGM or to appoint someone 
else to vote on your behalf:

Notes:

1. 

 To be entitled to attend and vote at the AGM (and for the purpose of the determination by the Company of the number of votes they may cast), shareholders must be registered in the 
Register of Members of the Company at close of trading on 17 May 2019. Changes to the Register of Members after the relevant deadline shall be disregarded in determining the rights of 
any person to attend and vote at the AGM. 

2.    Shareholders, or their proxies, intending to attend the AGM in person are requested, if possible, to arrive at the AGM venue at least 20 minutes prior to the commencement of the AGM at 

11.00 am (UK time) on 21 May 2019 so that their shareholding may be checked against the Company’s Register of Members and attendances recorded.

3.    Shareholders are entitled to appoint another person as a proxy to exercise all or part of their rights to attend and to speak and vote on their behalf at the AGM. A shareholder may appoint 
more than one proxy in relation to the AGM provided that each proxy is appointed to exercise the rights attached to a different ordinary share or ordinary shares held by that shareholder.  
A proxy need not be a shareholder of the Company. 

4. 

5. 

 In the case of joint holders, where more than one of the joint holders purports to appoint a proxy, only the appointment submitted by the most senior holder will be accepted. Seniority is 
determined by the order in which the names of the joint holders appear in the Company’s Register of Members in respect of the joint holding (the first named being the most senior).

 A vote withheld is not a vote in law, which means that the vote will not be counted in the calculation of votes for or against the resolution. If no voting indication is given, your proxy will vote 
or abstain from voting at his or her discretion. Your proxy will vote (or abstain from voting) as he or she thinks fit in relation to any other matter which is put before the AGM.

6.  You can vote either:

•  by logging on to www.signalshares.com and following the instructions;

•   If you need help with voting online, or require a paper proxy form, please contact our Registrar, Link Asset Services, on 0871 664 0391 if calling from the UK, or +44 (0) 371 664 0391  
if calling from outside of the UK, or email Link at enquiries@linkgroup.co.uk. Calls cost 12p per minute plus your phone company’s access charge. Calls outside the United Kingdom 
will be charged at the applicable international rate. Lines are open between 09:00 – 17:30, Monday to Friday excluding public holidays in England and Wales.

•  in the case of CREST members, by utilising the CREST electronic proxy appointment service in accordance with the procedures set out below.

In each case the appointment of a proxy must be received by Link Asset Services at 34 Beckenham Road, Beckenham, Kent, BR3 4TU by 11.00 am on 17 May 2019.

7. 

8. 

9. 

 If you return more than one proxy appointment, either by paper or electronic communication, the appointment received last by the Registrar before the latest time for the receipt of proxies 
will take precedence. You are advised to read the terms and conditions of use carefully. Electronic communication facilities are open to all shareholders and those who use them will not be 
disadvantaged.

 The return of a completed form of proxy, electronic filing or any CREST Proxy Instruction (as described in note 11 below) will not prevent a shareholder from attending the AGM and voting in 
person if he/she wishes to do so.

 CREST members who wish to appoint a proxy or proxies through the CREST electronic proxy appointment service may do so for the AGM (and any adjournment of the AGM) by using the 
procedures described in the CREST Manual (available from www.euroclear.com/site/public/EUI). CREST Personal Members or other CREST sponsored members, and those CREST members 
who have appointed a service provider(s), should refer to their CREST sponsor or voting service provider(s), who will be able to take the appropriate action on their behalf.

10.  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 issuer’s agent (ID RA10) by 11.00 am on 17 May 2019. For this purpose, the time of receipt will be taken to mean the time (as determined by the 
timestamp applied to the message by the CREST application host) from which the issuer’s agent is able to retrieve the message by enquiry to CREST in the manner prescribed by CREST.  
After this time, any change of instructions to proxies appointed through CREST should be communicated to the appointee through other means.

11.   CREST members and, where applicable, their CREST sponsors or voting service providers should note that Euroclear UK & Ireland Limited does not make available special procedures in 
CREST for any particular message. 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(s), to procure that his CREST sponsor or 
voting service provider(s) take(s)) 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 sponsors or voting system providers 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.

12.   Any corporation which is a shareholder can appoint one or more corporate representatives who may exercise on its behalf all of its powers as a shareholder provided that no more than one 

corporate representative exercises powers in relation to the same shares.

13.   As at 10 April 2019 (being the latest practicable business day prior to the publication of this Notice), the Company’s ordinary issued share capital consists of 401,995,161 ordinary shares, 

carrying one vote each. Therefore, the total voting rights in the Company as at 10 April 2019 are 401,995,161.

14.  Under Section 527 of the Companies Act 2006, shareholders meeting the threshold requirements set out in that section have the right to require the Company to publish on a website  

a statement setting out any matter relating to: (i) the audit of the Company’s financial statements (including the Auditor’s Report and the conduct of the audit) that are to be laid before  
the AGM; or (ii) any circumstances connected with an auditor of the Company ceasing to hold office since the previous AGM at which annual financial statements and reports were laid in  
accordance with Section 437 of the Companies Act 2006 (in each case) that the shareholders propose to raise at the relevant AGM. The Company may not require the shareholders  
requesting any such website publication to pay its expenses in complying with Sections 527 or 528 of the Companies Act 2006. Where the Company is required to place a statement on 
a website under Section 527 of the Companies Act 2006, it must forward the statement to the Company’s auditor not later than the time when it makes the statement available on the 
website. The business which may be dealt with at the AGM for the relevant financial year includes any statement that the Company has been required under Section 527 of the Companies 
Act 2006 to publish on a website.

15.   Any shareholder attending the AGM has the right to ask questions. The Company must cause to be answered any such question relating to the business being dealt with at the AGM but 

no such answer need be given if: (a) to do so would interfere unduly with the preparation for the AGM or involve the disclosure of confidential information; (b) the answer has already been 
given on a website in the form of an answer to a question; or (c) it is undesirable in the interests of the Company or the good order of the AGM that the question be answered.

16.  The following documents are available for inspection during normal business hours at the registered office of the Company on any business day from the date of this Notice until the time of 

the AGM and may also be inspected at the AGM venue, as specified in this Notice, from 10.00 am on the day of the AGM until the conclusion of the AGM:

copies of the Directors’ letters of appointment or service contracts.

17.   You may not use any electronic address (within the meaning of Section 333(4) of the Companies Act 2006) provided in either this Notice or any related documents (including the form of
