in the face of macroeconomic uncertainty, due to the 
strength of our differentiated model and proposition. 
As we focus on market opportunities with strong 
and enduring drivers, our differentiated approach 
provides us with distinct competitive advantages.

5G private network roll-outs are still in their infancy.

We go to market differently
We have evolved our customer relationships, 
engaging in more consultative selling, and becoming 
a trusted partner that understands our customers’ 
newer, larger business challenges and addresses

our investments on the faster-growing market 
areas that are most critical to our customers, 
both organically and through highly selective, 
earnings-accretive acquisitions.

Robust, sustainable operating model
We focus on retaining our key talent while 
pursuing a policy of diversity and inclusion, 
and we proactively manage our supply chain to 
minimise customer disruption. Our commitment 
to sustainability led to us achieving carbon 
neutral certification in 2022.

STRATEGIC REPORTEnabling rapid change spotlight

Enabling 5G 
cloud-native 
evolution through 
automation 

Facing a triple challenge, one of Europe’s leading service 
providers asked Spirent to help tackle its complex needs 
and aggressive timelines. Working to move to its own 
cloud platform for the core network and to accelerate its 
standalone 5G cloud-native evolution, the operator was at 
the same time contending with combining the systems of two 
separate brands and having to address the mammoth task 
of swapping out much of its existing infrastructure hardware 
with solutions from new suppliers.

Needing to test the new multi-vendor system and make 
sure it delivered end-to-end performance and capacity 
under load, the provider needed to stress test the combined 
systems. It also needed to perform validation in pre-
production environments and ensure consistency with its 
lab environments to streamline internal workflows, support 
continuous integration/continuous development (CI/CD) 
practices and embrace automation. 

To address the lack of necessary in-house skills to perform 
pre-production validation of a cloud-native telco cloud, 
Spirent, along with third party vendors, deployed a Test-as-a-
Service solution, providing managed services to leverage the 
provider’s existing Spirent Landslide licences to validate that 
the swap-out project could deliver end-to-end performance 
and meet capacity requirements. Spirent VisionWorks was 
also deployed for pre-production validation and active 
assurance testing to assess pre-deployment infrastructure. 

Spirent’s solution is providing the customer with the 
confidence to proceed with its migration project, ensuring the 
network continues to deliver the performance and scalability 
that its customers expect, protecting revenues and the 
customer’s brand.

STRATEGIC REPORTPowering test 
for India’s 5G 
superpower push

Having allocated its 5G spectrum, the government of India is 
determined to be a world 5G superpower. Leading the way in 
this rapid change is a top-tier Indian network provider, which 
committed itself to deploying the nation’s first standalone 
5G network capable of delivering new and powerful 
5G-enabled services.

Spirent has worked with the network provider’s R&D team and 
its dedicated quality assurance labs for many years. As it built 
its own 5G network capabilities, the provider recognised the 
challenge of both producing and testing its own innovations. 
To address this, the customer created an independent live 
network validation hub, run by a new network team. Without 
deep competencies in testing of its own, the new team turned 
to Spirent and its Test-as-a-Service capabilities to provide a 
hybrid managed solution that delivers the customer’s detailed 
test requirements and can be rapidly delivered and scaled 
as required. 

The customer opted to purchase Spirent’s class-leading 
technology, that included Landslide and Velocity and to use 
the experienced Spirent team to run validation as a managed 
service. Focused on 5G SA core, cloud infrastructure and 
security, the solution is further enabled by Spirent’s extensive 
automation, reinforcing the strong collaboration between 
the two companies.

We are committed to 
providing a cloud-native, 
hyperscale 5G core network 
and our collaboration with 
Spirent is an important part 
of achieving this objective.

Chairman’s statement

Well positioned 
to support our 
customers

I am pleased to present our Annual Report for the year 
to 31 December 2022. 

Performance during the year
Our performance through the year demonstrated our ability 
to maximise market opportunities in areas such as 5G, 
capitalise on growth outside our more traditional geographic 
markets and innovate our solutions and services offerings to 
solve bigger more complex problems for our customers. In the 
latter part of the year we began to see the impact of the wider 
softening in the macroeconomic environment and we saw 
delays in customer purchasing decisions.

I am very pleased to see another year of strong progress that 
we have made as a business. Revenue increased by 5 per 
cent to $607.5 million and we achieved a 9 per cent increase 
in adjusted operating profit1, and a 14 per cent increase in 
adjusted basic earnings per share2. Reported profit before tax 
was up by $11.0 million to $114.6 million (2021 $103.6 million). 
In line with our progressive dividend policy we are proposing 
a 12 per cent increase to the full year dividend. This represents 
the sixth consecutive year of growth in revenue, profitability 
and dividend.

I am also pleased to see that the work we have undertaken in 
the last few years sees us enter into more uncertain economic 
times with orderbook at an all time high, and helps to give 
us more predictability over future revenue streams than has 
historically been the case.

The Board notes the level of net cash we currently hold and 
confirms that we continue to look at a range of opportunities 
to grow the business, whether through organic or inorganic 
opportunities. We expect the current market to potentially offer 
us more attractive inorganic opportunities to explore in 2023 
and beyond. We were delighted that the octoScope business 
purchased in 2021 performed well in 2022 and we see the 
path to future growth in the Wi-Fi space. This performance 
gives us confidence in our ability to identify the right inorganic 
opportunities for Spirent.

STRATEGIC REPORTOur employees and the right culture
It is our colleagues, through their innovation, ingenuity, hard 
work and resilience that deliver results of the quality that we 
present in this year’s Annual Report. I want to thank all of 
them for their continued support. Through their efforts we 
have delivered exciting new products, grown in new customer 
verticals, delivered more complex services offerings and 
managed the impacts of the supply chain interruptions 
that still persist.

These achievements were made while adhering to the core 
values and ways of working that the Board sponsors and 
promotes across the Company.

The Board continues to invest time, effort and energy in our 
engagement with the wider workforce. By using three of our 
Non-executive Directors to engage with and receive feedback 
from our employees across all three of the regions in which 
we do business, we aim to understand how our strategic 
initiatives have taken root across the business. 

Each year we seek to engage and have a constructive dialogue 
with different groups of employees so we understand the 
views of as diverse a group as possible, whether they be 
colleagues from engineering, sales or supply chain, and 
whether they work on site, flexibly or remotely.

We also monitor the long-term trends of employee engagement 
with our annual employee engagement survey where we 
continue to see good levels of engagement and high levels 
of participation. 

Sustainability
In late 2020, Spirent set an ambitious Sustainability Strategy 
with medium and long-term goals. Our strategy and goals 
are set out publicly in our annual Sustainability Report as is 
the progress we have made against those goals. In 2022, 
we have worked to determine the initiatives that will help 
us deliver our energy and carbon reduction goals over the 
short and medium term. We have achieved carbon neutral 
certification during 2022 and have also made significant 
progress in calculating our Scope 3 emissions. 

Outlook
We continue to invest in our market-leading technologies 
to support our customers with their development plans 
particularly as 5G roll-out continues.

Since the fourth quarter of 2022 we have seen delays to 
some of our customers’ decision making and whilst we expect 
a more challenging first half of 2023, our business drivers 
remain intact and our mid-term targets remain unchanged.

We saw some customers exercise caution towards the end of 
last year in response to broader macroeconomic conditions 
and this was most notable amongst customers for our 5G  
lab-based Lifecycle Service Assurance applications.

We have proactively engaged with our customers and the 
feedback reiterates their intention to continue to develop 
and implement their 5G infrastructure, and we therefore 
expect momentum to improve in the second half of the new 
financial year.

Spirent Communications plc Annual Report 2022

2022 was another year of strong strategic execution as 
we sustained our growth trajectory in the face of current 
macroeconomic challenges and, in the final quarter, signs 
of caution in our customers’ spending patterns. Despite the 
disruption caused by inflation, COVID-19 and global conflicts, 
our world-class team continued to innovate, to deliver for our 
customers and to win larger deals across the globe. 

Market overview
Our key market drivers have remained strong, led by 5G 
and driven by global trends such as work from anywhere, the 
emergence of the metaverse, the expansion of hyperscalers, 
and location awareness as a key application enabler. As the 
only vendor addressing all phases of the technology lifecycle, 
from end to end we consolidated our 5G leadership during 
the year, applying our innovation to test, automate and assure 
opportunities in labs through to deployment and operation 
of live networks. We continued to make significant progress 
in our ambition to address our customers’ larger and most 
pressing business concerns, such as cost reduction and 
energy efficiency, by driving services and solutions growth 
across our portfolio. We are confident in the enduring nature 
of our structural growth drivers, despite near-term market 
conditions, and our customers remain committed to their 
investment plans particularly in relation to 5G roll-outs.

Strategy
To realise our ambition to be the global leader and trusted partner 
for innovative technology test and assurance solutions, 2022 saw 
us continue to focus on our proven strategic pillars: Customer 
Centricity, Innovation for Growth and Operational Excellence.

Customer Centricity
We continued to make significant progress during 2022 in our 
ambition to address our customers’ larger business problems 
by driving outcome-based services and solutions across our 
portfolio. The shift from selling features and functions to selling 
outcomes and value resulted in larger deal sizes and has 
enhanced closeness to our customers, helping to cement our 
importance in customer accounts during a time of increasing 
macroeconomic uncertainty and caution around capital and 
operational expenditure. 

Our role as a trusted partner to our customers drove us 
forward growing into new segments and markets. We 
supported over 1,100 customers across more than 50 countries 
in 2022, including over 260 new customers in 33 countries. 
Spirent’s customer base continues to be highly diversified, 
with no single customer accounting for more than 9 per cent 
of total revenue in 2022. 

At Spirent, we are constantly improving the ways in which 
we go to market. We continued to strategically expand our 
successful key account programme. Our partner ecosystem 
once again delivered good results as we targeted faster-
growing segments and regions. Our technology-led services 
portfolio delivered another year of double-digit growth as we 
delivered large-scale services to customers around the world. 
Engagements led by services and solutions are increasing 
the size of our deals and are enabling us to strategically 
partner with customers to automate, validate and optimise 
their networks. This strategic progress led further growth of 
our orderbook, which stood at $288.1 million at the end of 
the year, representing 7 per cent year-on-year growth.

STRATEGIC REPORTInnovation for Growth
To sustain and grow our global leadership in test and 
assurance it is critical that we make smart investments, 
both organic and inorganic, that address emerging market 
and technology opportunities. We invested 18.3 per cent of 
revenue in research and development in 2022. 5G remains 
the enduring driver for our business, with over 800 5G-related 
wins in the period and significant progress in our journey from 
the lab to deployment and operation of live networks. We 
brought several key new solutions and services to market in 
2022 that clearly showcased our market-leading expertise. 
We executed well on our product road maps, whilst also 
implementing our site strategy to drive cost efficiency as we 
transferred R&D roles from higher-cost North American sites 
to Eastern Europe and India without losing momentum.

In the third quarter we announced the introduction of 
Spirent Vantage, an innovative solution that applies Spirent’s  
industry-leading technology and subject matter expertise to 
dramatically simplify and automate 5G service assurance for 
communications service providers (CSPs). With its comprehensive 
turnkey approach that allows operations teams of any size 
and skill to understand their network and service performance, 
Vantage broadens our addressable live market beyond the 
top-tier CSPs targeted by our existing VisionWorks solution. 

The Wi-Fi business we acquired as octoScope in 2021 saw 
strong growth during the period, driven by the widespread 
adoption of Wi-Fi 6 and 6E, together with our new Test-as-a-
Service (TaaS) offering for Wi-Fi equipment. We also launched 
an industry-first, fully integrated and automated Open RAN 
(O-RAN) wrap-around test solution to address emerging 
O-RAN market opportunities.

We expanded our leadership in high-speed Ethernet test with 
the release of the industry’s first 800G test platform which saw 
success with vendors designing, developing and deploying 
800G technologies, including a public 800G interoperability 
demonstration with Nokia. We also announced a new 400G 
Ethernet test platform and added a 400G capability to our 
application security performance test solution. Customer 
demand for lower port speeds such as 100G was also 
strong, driven by backbone network upgrades in the face 
of continuing data growth.

Our Positioning business delivered the first high-accuracy 
orbital modelling software solution, specifically targeted at 
emerging opportunities in the Low Earth Orbit (LEO) segment. 
I am also proud to note that the Positioning business was 
honoured with a prestigious Queen’s Award for Enterprise in 
the UK, which recognises excellence in international trade.

Operational Excellence
Our commitment to operational excellence and our robust 
operating model are key differentiators, critical to our continued 
success in uncertain times. We diligently managed our cost 
base in 2022 while making the smart investments needed to 
underpin our future growth. We successfully implemented our 
engineering site strategy to transfer resource to lower cost 
regions driving savings for our high-speed Ethernet business. 
Our world-class supply chain team enabled us to deliver in 
the face of challenges throughout the year. We were able 
to compensate from ongoing turbulence in the geopolitical 
landscape with China through expansion of our customer 
base and development of new market opportunities in the 
APAC region. 

We invested once again in enhancing our go-to-market 
capabilities, strengthening our inside sales capabilities across 
all regions and bolstering our solutions and services selling

has now been achieved. We also calculated our total Scope 3 
emissions during the year, providing us with a comprehensive 
view of our carbon emissions across all sources, which will 
enable us to report more widely against our carbon emission 
reduction goals going forward. You can read more about the 
full scope of our work in the area of ESG on pages 32 to 36 
and in our annual Sustainability Report.

Capital allocation approach
Our highly effective financial and operational management 
delivered another year of strong free cash flow and our 
balance sheet remains strong and working capital remains 
very efficient. We continue to implement our capital allocation 
policy along the lines previously stated. We invest in R&D to 
maintain and expand our leadership positions in the market, 
and in inorganic investments where we see attractive 
opportunities that support our strategic growth agenda, 
whilst still maintaining sensible levels of cash.

STRATEGIC REPORTGNSS innovation 
keeping the 
autonomous 
future on track

A leading manufacturer of autonomous open-pit mining haul 
trucks has adopted Spirent’s pioneering positioning solution 
to advise its customers about the availability of autonomous 
operations. Spirent GNSS Foresight is the first-of-its-kind cloud-
based solution that enables operators to know in advance 
where and when global navigation satellite system (GNSS) 
positioning is reliable for unmanned and autonomous journeys. 

To operate autonomous haul trucks safely, each mine operator 
has a ‘minimum full autonomy mode capability’ guidance 
requirement. In such environments, existing GNSS performance 
can be unpredictable due to signals being obscured or blocked, 
reducing the capacity to provide accurate positioning. With GNSS 
Foresight Risk Analysis, a GNSS-alternative sensor solution can 
be added to the haul vehicle by the manufacturer, enabling 
Spirent GNSS Foresight to share an assessment report of 
where and when GNSS will work well based on the mine’s 
current configuration. Using the mine operator’s excavation 
plans, this can be done up to five years into the future, and if 
excavation plans change, a new GNSS Foresight Risk Analysis 
can be provided. 

Spirent GNSS Foresight’s ability to accurately predict 
autonomous performance is enabling the mining, quarrying, 
ports and construction industries to enhance safety, efficiency 
and return on investment through operational improvements.

Spirent GNSS Foresight enables 
operators to enhance efficiency, 
safety and return on investment 
through the resulting operational 
improvements.

•  diversity and inclusion; 

•  sustainability; 

•  work-life balance; and

•  sense of fun. 

The campaign has also allowed us to recognise the 
incredible talent we already have within our business.

We introduced a range of enhanced, global family 
leave benefits to provide our people with additional 
flexibility when they and their families need it the most: 

•  we increased our parental leave entitlement for 

primary and secondary caregivers; 

•  we increased our bereavement leave; and

•  we introduced family care leave to care for 

immediate family members. 

These enhanced benefits have been well utilised and 
the feedback from our people tells us they have made 
a real difference to their work-life balance. 

Our culture in action: volunteer time off

I assisted with a pre-event 
trail clean-up and log 
cutting and ran an aid 
station as part of an 
annual fundraiser to 
maintain the Allegrippis 
bike trails in Pennsylvania. 

I supported my daughter and 
her friends in establishing 
their school food waste 
composting programme and 
chaperoned them on a visit to 
Maryland Senate and House 
to advocate for their cause.

I helped organise a marathon 
to raise funds for a local 
charity, which provides free, 
fun-filled holidays for families 
with seriously ill children, 
terminally ill parents, or 
recently bereaved.

STRATEGIC REPORT 
 
 
 
 
Spotlight on 5G

Our strategy is 
aligned to support 
5G’s race

5G’s race to revenue
At the end of 2022, Spirent estimated there were over 1 billion 
5G subscriptions across more than 95 countries worldwide. 
Analysts predict that by the end of 2026, the total worldwide 
5G service market will exceed $249 billion4, driven by a 
combination of consumer demand for faster data speeds, 
enterprise adoption as part of their digital transformation, 
and government policies aimed at boosting economic 
development and ensuring supply chain security.

So far, operators have mainly focused on building 5G radio 
networks to leverage their spectrum assets, provide basic 
national coverage, and offer an initial 5G (non-standalone 5G) 
service. While coverage build outs and network densification 
will continue for many more years, some leading operators 
are starting to move to the “full” version of 5G (standalone 5G) 
in pursuit of the cloud-native and agile capabilities provided 
by the introduction of the 5G core network, which is key to 
enabling them to unlock new revenue-generating use cases 
across consumer and private enterprise markets.

However, it is still early days for standalone 5G deployments. 
Only about 15 per cent of commercial 5G network operators 
globally2 have upgraded to a true 5G core network, providing 
an enduring test and assurance opportunity for Spirent.

5G, collaboration and the enterprise 
The costs involved in bringing 5G to market are immense. With 
limited opportunities to unlock new revenue from basic 5G 
connectivity, leading operators are now preparing networks 
and business offerings to engage in lucrative enterprise 
markets and to bring advanced use cases to consumers.

Over the next two years, these leaders will move rapidly to 
standalone 5G, while aiming to transform into digital service 
providers in pursuit of agility and differentiation, incrementally 
adding new capabilities required to service demanding 
enterprise use cases.

Collaboration between operators and cloud hyperscalers will 
continue to grow as operators augment their offerings with 
public and private edge services. Initiatives around “open” 
radio access networks and network lifecycle automation will 
continue to gain momentum as the industry strives for greater 
vendor diversification, agility and energy efficiency. Non-terrestrial 
networks will become more prevalent as operators partner 
with satellite providers to deliver new direct-to-phone services.

Spirent’s 5G strategy is well aligned to support this race. 
An acknowledged industry leader in 5G core and transport 
network testing, offering innovative solutions such as automated 
and continuous testing and assurance, together with flexible 
business models such as Test-as-a-Service, Spirent is 
helping its customers accelerate their time to market and to 
new revenues.

Spirent’s strategy is well aligned to 
support the 5G race. Our innovative 
solutions and flexible business models 
help our customers accelerate time 
to market and time to new revenues.

time to market 

The ongoing deployment of 5G highlights 
its dependency on a high-capacity, 
tightly synchronised, low-latency and 
secure transport network capable 
of supporting a disaggregated 5G 
network with thousands more cell sites, 
new edge locations and geographically 
distributed data centres.

As an industry leader in high-speed 
Ethernet and application-aware 
security testing, Spirent has been 
helping the industry future-proof 
its network scalability, security 
and the evolution to edge clouds

in 2022 in the world’s largest 5G 
region, validating multi-speed network 
equipment and security efficacy from 
multiple vendors to support aggressive 
nationwide deployments.

Delivering critical 5G 
test and assurance as 
a service
5G’s increased complexity, combined 
with an exponential increase in the 
velocity and volume of software 
releases, inconsistent tools and 
processes, and a lack of in-house 
expertise, presents major challenges 
to our customers.

Managed Solutions help address these 
challenges by offering unparalleled 
subject matter expertise, tools and 
methodologies as a service, enabling 
an innovation pipeline between 
development and operations.

Spirent’s managed solutions leadership 
was showcased in 2022 at a leading

STRATEGIC REPORT 
 
Lab-to-live lifecycle needs 

Lab

Live

As our customers grapple with cloud networking 
complexity, the need to shift from a telco to IT 
mindset, and the implications of an expanding 
vendor ecosystem, they are transforming technology 
development in the lab with agile, continuous 
integration and continuous deployment (CI/CD) 
practices. Adoption of CI/CD faces headwinds as 
required cloud, security and automation skills are 
in short supply across many industries.

The transformation to CI/CD brings with it a 
heightened pace of technology releases which 
must be rapidly deployed to live environments. 
At the same time, new services and applications 
from edge computing to drone navigation come 
with higher performance expectations. Legacy, 
manual processes for deploying and operating new 
technology must give way to automated turn-up, 
monitoring and troubleshooting.

Spirent’s unique value

Accelerate time to market
With years of leadership in automated cloud, 
network and security testing, Spirent has the 
expertise, test platforms and services to provide 
our customers solutions to rapidly adopt CI/CD 
and achieve new levels of agility.

Optimise user experience
Our Active Test technology proactively and 
continuously monitors cloud-based networks 
and services, automatically isolating problems 
and ensuring service levels are maintained.

Bring new technology releases 
to market in weeks, not months

Rapidly find, pinpoint and 
fix issues before end-users 
are impacted

Reduce cost and complexity
Our certification and validation solutions recreate 
real-world conditions such as heavy traffic loads to 
help the industry ensure new multi-vendor networks, 
devices and services perform flawlessly together. 

Harden security defences
As telco networks become software running on 
the cloud, the cybersecurity attack surface expands 
exponentially. Our security solutions recreate  
real-world cyberattacks and scan for vulnerabilities 
to allow proactive mitigation.

Manage vendors to keep 
costs and rising deployment 
complexity in check

Proactively find security 
weaknesses and prepare for 
attacks before they happen

STRATEGIC REPORTKey performance indicators

Strategy 
in action – 
demonstrable 
progress

Spirent’s strategy focuses on medium to long-term 
growth and therefore its achievement cannot be 
measured by just looking at performance in 2022 
compared to the prior year; trends over a number 
of years must also be considered. Executive Director 
remuneration is linked to certain financial, strategic 
and operational key performance indicators (KPIs) 
with further information available in the Report on 
Directors’ Remuneration on pages 83 to 110.

Reason for measurement
The ratio of orders booked 
to revenue recognised is a 
measure of the visibility of 
future revenue at current 
levels of activity and 
provides an indication of the 
underlying trend in Spirent’s 
future revenue stream.

Performance
Order intake was greater 
than revenue in the year 
resulting in a book to bill ratio 
of 103 as we continue to win 
larger, longer-term contracts 
that improve revenue 
visibility and build repeatable 
business. 2021 was a strong 
comparator year from an 
orders perspective.

Relevance to strategy
The book to bill ratio is an 
indicator of the underpin to 
future revenue and whether 
activity levels are rising or 
slowing, and therefore how 
effective we have been in the 
execution of our strategy.

Reason for measurement
Spirent monitors growth in 
revenue as this shows how 
successful Spirent has been 
in expanding its markets and 
growing its customer base.

Reason for measurement
Adjusted operating profit 
is the measure used 
to evaluate the overall 
performance of the Group 
as well as each of the 
operating segments. 

Reason for measurement
Adjusted operating margin 
is a measure of the Group’s 
profitability. Spirent operates 
in markets which have high 
operating returns and strives 
to achieve best-in-class 
operating margin compared 
with its peers.

Performance
5.5 per cent revenue 
increase in 2022, following a 
10.3 per cent increase in 2021. 
5G continues to be a strong 
driver of growth across our 
solution portfolio.

Performance
Adjusted operating profit 
increased by 9.3 per cent to 
$129.5 million, from $118.5 
million in 2021, as a result 
of revenue growth and 
effective cost management.

Performance
The increase in adjusted 
operating margin to 21.3 per 
cent, from 20.6 per cent in 
2021, reflects a combination 
of revenue growth and 
continued cost management.

Relevance to strategy
Revenue demonstrates 
the effectiveness of our 
strategy: our success in 
expanding our markets both 
organically and through 
acquisition; maintaining 
technology leadership; and 
our strong relationships with 
our customers, all of which 
ensure that we continue to 
win and maintain business.

Relevance to strategy
Adjusted operating profit 
indicates our financial 
strength and our ability 
to invest in the business 
for future growth. 

Relevance to strategy
Adjusted operating margin is 
a measure of how successful 
we are in our overall strategy 
and demonstrates our ability 
to improve profitability 
through efficient operations 
whilst being mindful of the 
need to invest for the future.

Reason for measurement
Long-term growth in 
adjusted basic EPS 
is a fundamental 
driver to increasing 
shareholder value.

Reason for measurement
To maintain its competitive 
position, Spirent must invest 
at suitable levels to support 
further organic growth 
initiatives in line with the 
strategic objectives, whilst 
driving improved productivity 
and effectiveness.

Performance
Spirent aims to achieve 
growth in adjusted basic 
EPS. Part of the Executive 
Directors’ remuneration is 
dependent on achieving EPS 
targets. In 2022, adjusted 
basic EPS grew 13.7 per cent 
as a result of the increase in 
adjusted earnings.

Performance
In 2022, product 
development spend of 
18.3 per cent of revenue was 
slightly down in comparison 
to 2021 (19.7 per cent) due to 
more targeted investment. 
The spend in absolute 
terms was $111.3 million 
(2021 $113.3 million).

Reason for measurement
Spirent’s success is 
dependent on its talented 
employees and retaining 
them is extremely important. 
Voluntary employee turnover 
compared to the industry 
average is the measure used 
to assess how well the Group 
has performed.

Performance
Our 2022 voluntary 
turnover rate of 10.1 per 
cent remains well below the 
global industry average of 
19.5 per cent.

Relevance to strategy
Adjusted basic earnings per 
share is a measure of how 
successful we are in our 
strategy and ultimately how 
Spirent increases value for 
its shareholders.

Relevance to strategy
It is critical that Spirent’s 
product development 
investment keeps pace 
with the speed of change 
in technology, and that 
it is directed at the right 
key technology areas; 
this enables us to expand 
our markets and to 
maintain our technology 
leadership position.

Relevance to strategy
We cannot avoid the fact 
that some of our employees 
will move on but we can 
avoid a skills shortage by 
appropriately managing, 
recognising and rewarding 
our people. Voluntary 
employee turnover is a 
measure of how successful 
Spirent is in its strategy of 
retaining and investing in 
its people.

Reason for measurement
Free cash flow is a measure 
of the quality of Spirent’s 
earnings. The aim is to 
achieve a high conversion 
of earnings into cash.

Performance
Free cash flow in 2022 was 
strong at $103.8 million, driven 
by continued effective working 
capital management. Free 
cash flow conversion for 
2022 was 91 per cent of 
adjusted earnings (2021 
91 per cent).

Relevance to strategy
Having strong free cash flow 
reflects Spirent’s ability to 
generate funds for future 
investment. It provides 
financial strength and 
flexibility and the ability to 
pay sustainable dividends 
to our shareholders.

STRATEGIC REPORTStakeholder engagement

Considering 
stakeholders 
in key business 
decisions

Business does not operate 
in isolation. Without a good 
understanding of who its key 
stakeholders are and their differing 
perspectives, a business will fail to 
deliver sustainable growth to 
shareholders and other stakeholders.
Board Directors are bound by their duties under 
the Companies Act 2006 (the “2006 Act”), but 
the principles underpinning Section 172 are not 
only considered at Board level, they form part 
of everything we do as a Company.

Supported by the Company Secretary & General 
Counsel, the Board, management and anyone 
tasked with preparation of Board materials 
give consideration to relevant stakeholders in 
matters requiring decision making, including 
strategic decisions.

Statement and set out how the Board has, in 
performing its duties over the course of the year, 
had regard to the matters set out in Section 172(1)

Key Board decisions and 
Section 172 considerations 
The following are examples of some of the principal decisions 
made by the Board during the year under review which 
demonstrate how employee interests, the need to foster 
business relationships with other key stakeholders and 
other Section 172 matters have been taken into account 
in discussions and decision making.

Further development of the Sustainability Strategy
The Executive Director-led Management Committee on ESG 
matters held meetings throughout the year. Issues discussed 
by the Committee were communicated to the Board by the 
CEO, Eric Updyke, and the Board in turn provided feedback 
on the direction of the Group’s Sustainability Strategy. In 
addition, in order to ensure full awareness of the Group’s 
performance against its sustainability targets and to inform 
decisions on strategy and operational direction, the Board 
received a detailed management update in December 2022. 
Further details of the Group’s Sustainability Strategy can 
be found on pages 32 to 39 of this Annual Report and in its 
Sustainability Report, which can be found on the Company’s 
website at corporate.spirent.com.

Retirement benefits for former and current 
employees
During the year, the Board supported the Group in securing 
its defined benefit pension scheme liabilities through an 
insurance buy-in, removing risk exposures on the Group’s 
balance sheet. After taking advice from independent pension 
advisers and working with the Plan Trustees, the Group and 
Trustees launched a tender process to select a specialist 
insurer to provide strong administrative capability alongside 
good financial strength and resilience. The Board reviewed 
and approved the project plan and received updates 
throughout the tender process, considering the benefits to 
members of the two plans in addition to the potential impact 
for current employees and shareholders.

The Board and Remuneration Committee also considered a 
review of employee and employer contribution levels in the 
current UK retirement benefit offering. The Board reviewed a 
proposal to introduce a higher contribution band for the UK 
workforce and agreed that this would aid the attraction and 
retention of talent, in particular in engineering and sales.

While considering retirement benefits, the Board and 
Remuneration Committee also reviewed the 401(k) and 
Deferred Compensation Scheme offered to US employees, 
looking at a number of ways to improve the offering while 
being mindful of the financial impact of any changes to 
the Group. Following a benchmarking exercise, the Group 
now expects to introduce incremental improvements to the 
schemes in the coming years to bring them into line with 
those offered by other companies that are competing in 
the same talent pools.

STRATEGIC REPORTEnabling rapid change spotlight

Spirent’s solution is 
performing over 250,000 
proactive, continuous health 
checks on the customer’s 
network every single day.

Assurance, Spirent

Checking network 
health 250,000 
times a day 

Delivering core services to over 100 million business and 
consumer customers each day, a North American tier-one 
operator needed to accelerate its 5G standalone (SA)  
cloud-native evolution. Identifying an expansion of its automation 
and proactive ‘health checks’ approach through scalable test 
tools with a single interface, the operator looked to Spirent 
for guidance.

As part of its ongoing collaboration with Spirent, VisionWorks 
Mobility Service Assurance (MSA) had previously been 
deployed by the operator to deliver proactive health 
checks and help align testing across lab and live domains. 
With manual network monitoring no longer manageable, 
the customer wanted to scale the automation process to 
embrace additional key areas, including validation of new 
deployments, continuous active monitoring with increased 
health checks, and ad hoc testing to accelerate issue 
isolation and resolution.

Working closely with Spirent, the customer defined the health 
check requirements and Spirent, utilising VisionWorks MSA 
and Landslide, configured the network emulation synthetic 
traffic generation of the active test agents. With more tests in 
more locations required to ensure full, proactive visibility of 
the network, Spirent’s solution can now perform over 250,000 
daily proactive, continuous network health checks. This 
enables the customer to support lab, First Field Application 
(FFA) deployments and live network domains with a cohesive, 
automated test and assurance capability that supports agile 
CI/CD practices.

encouraging employees to take pride in working for us; and

•  reducing the risk of incidents and their associated costs.

Our material sustainability issues
Our material sustainability issues were updated in 2022 
using a risk-based approach. The review identified climate 
change and carbon neutrality as priority issues, including the 
role our solutions can play in helping our customers reduce 
their impacts. Diversity, equity and inclusion, staff health and 
wellbeing were identified as important, along with responsible 
business practices, sustainable product design, human and 
labour rights, and robust sustainability governance. Water 
use is an emerging issue, especially in raw materials and 
manufacturing in supply chains.

Deliver a sustainable future
We aim to showcase the environmental benefits that our 
solutions deliver for customers and embed sustainability 
into our go-to-market strategy.

This year we worked with customers across the project 
lifecycle to help them improve their sustainability performance. 
From working with equipment manufacturers to test and 
validate new, more efficient components for 5G, to our work 
with lab and network operators to automate and streamline 
operations, Spirent is helping to drive the transition to a low-
carbon economy.

You can read more in our Sustainability Report which 
is available on our website at corporate.spirent.com.

Be net zero carbon
We set out to achieve CarbonNeutral® Company certification 
by 2023, and work towards net zero carbon by 2035 through 
energy efficiency, 100 per cent renewable electricity and 
carbon offsets.

During 2022, we achieved CarbonNeutral® Company 
certification for our Scope 1 and 2 and some Scope 3 
emissions sources for 2021 and 2022: electricity transmission 
and distribution, waste from building operations, business 
travel and homeworking.

We continued to source all our electricity from renewable 
sources through onsite generation at our Paignton site and 
the purchase of Energy Attribute Certificates (EACs).

When purchasing EACs and carbon credits, we have conducted 
due diligence to give us comfort as to their quality and 
traceability. We have only selected those from high-quality 
and reputable projects which are independently verified and 
verified to recognised global standards. We have worked with 
Climate Impact Partners to source carbon credits in line with 
our regional emissions and Ecohz to purchase national EACs 
based on our energy usage in each country we operate in.

We have also conducted a detailed energy efficiency audit 
of all our labs to support our long-term carbon and energy 
reduction target.

Energy use
Spirent is within scope of the Streamlined Energy and Carbon 
Reporting (SECR) Regulations. Spirent’s energy use increased 
by 1 per cent in 2022 to 13,157MWh (2021 13,019MWh). This is 
due to bringing source engineering functions in house, the 
roll out of a number of customer 5G labs and the increase 
in staff returning to the offices. It’s noted that 2021 energy 
use was artificially low as few employees were working from 
the offices due to COVID restrictions. Gas use decreased in 
the year by around 37 per cent to 344MWh (2021 548MWh). 
Purchased energy in the UK during 2022 was 718MWh 
(2021 719MWh).

During the year we continued to drive energy efficiency 
campaigns in labs and our buildings and conducted a detailed 
energy audit to identify further energy efficiency opportunities.

Spirent Communications plc Annual Report 2022

Greenhouse gas emissions
Spirent is committed to combating climate change and 
reporting our progress. Our total Scope 1 and 2 (location-based) 
emissions increased by 1 per cent from 2021, and our emissions 
per $ million of revenue were down by 4.2 per cent. We have 
reduced our total location-based emissions by 37 per cent 
since our 2014 baseline. Carbon emissions arising from 
our UK operations in 2022 were 134 tonnes CO2e (2021 150 
tonnes CO2e). Due to our purchasing 100 per cent renewable 
electricity, our contract-based emissions are significantly 
lower: 44.9 tonnes CO2e in 2022 (2021 99.5 tonnes CO2e).
During 2022, we completed a comprehensive review of our 
Scope 3 emissions and report all material emissions sources 
for the first time this year. The total Scope 3 emissions for 
the year is around 44,000 tonnes CO2e with the largest 
component of our Scope 3 footprint coming from customer 
use of our products. A full breakdown by source is set out in 
our Sustainability Report which is available on our website at 
corporate.spirent.com.

The Group responded to the Carbon Disclosure Project in 
2022, completing the Climate Change and Supply Chain 
questionnaires. In 2022, we achieved a Climate Change rating 
of C (awareness) (2021 A-). The average for our sector is B-. 
This reduction was due in part to not having a full Scope 3 
baseline and Science-Based Target approved by SBTi at the 
time of submission. We expect that progress in this area will 
be reflected in our score for 2023.

Methodology
Reporting on emission sources is required under the Companies 
Act 2006 (Strategic Report and Directors’ Report) Regulations 
2013 and these sources fall within our consolidated financial 
statements. We have reported on all the emission sources 
that fall within our consolidated financial statements.

We do not have any responsibility for any emission sources that 
are not included in our consolidated financial statements. We 
report our emissions using the location-based methodology. 
We have used the GHG Protocol Corporate Accounting 
and Reporting Standard (Revised Edition), along with data 
gathered to fulfil our requirements under these Regulations, 

STRATEGIC REPORTand the most recent emission factors available: UK Government 
GHG Conversion Factors for Company Reporting 2022 for the 
UK, US EPA 2022 eGrid emissions factors for the applicable 
individual states in the US, and the latest emissions factors for 
all other countries were sourced from the International Energy 
Agency’s 2022 data set.

Strategy
Spirent recognises the importance of climate change as an 
environmental threat that the world faces, and as such we 
have carefully considered the impact of such risk across our 
operations. Climate risks are entirely integrated into our risk 
management process. 

A “limited” level of assurance for the energy use and 
greenhouse gas emissions has been conducted, to meet 
the requirements of the International Standard on Assurance 
Engagements (ISAE) 3000 revised.

Performance against targets
We set a target to achieve CarbonNeutral® Company 
certification for the Group by 2023, and have achieved this 
target. The Group has set a target to reduce energy use 
by 25 per cent from 2019 levels by the end of 2025. In 2022 
our energy use was broadly flat on 2021 levels (excluding 
acquisitions). 

To the end of 2022 we have reduced energy use 
by 9.8 per cent.

Energy Savings Opportunity Scheme (ESOS)
Spirent qualifies for ESOS. We completed an ESOS 
compliance energy audit for Stage 2 and submitted the 
relevant disclosure to the Environment Agency. We are 
planning our participation in Stage 3.

Task Force on Climate-related 
Financial Disclosures (TCFD) 
Climate change creates new risks and opportunities for 
companies. In accordance with the requirements of Listing 
Rule 9.8.6R, Spirent has provided disclosures against all 11 
disclosure recommendations that span four key areas of 
governance, strategy and climate change scenario analysis, 
risk management, and metrics and targets.

Governance and risk management
The Board considers sustainability issues (including climate 
change) throughout the year and oversees the consideration 
of climate-related risks and opportunities under the TCFD 
disclosure requirements. 

In 2022, we expanded our sustainability governance 
structures, introducing a new executive sustainability 
committee and expanding the participation of our 
FuturePositive working group.

A detailed review of how climate change may impact 
our business in the future was completed in 2021 and the 
assumptions and findings were reviewed in 2022, with only 
minor changes being made. The significant climate-related 
risks and opportunities were identified and examined initially 
through a workshop with senior managers. These are 
reviewed on an ongoing basis by the Executive Director-led 
ESG Management Committee, the Audit Committee and its 
Risk Sub-Committee, as part of our business risk and financial 
planning processes. The materiality of the potential climate 
impact is assessed using the Group’s materiality criteria.

Over the course of 2022, a number of investors and customers 
have engaged with us on the importance of climate change, 
and we have incorporated their expectations into our 
materiality, strategy and reporting planning.

We have identified the following risks across a variety of 
time horizons. The risks consider the potential for increased 
exposure to extreme weather events at a Group location 
or key supply chain site. In addition, likely changes to 
the regulatory system in which the Group operates have 
been considered.

For the purpose of evaluating climate change-related risks, 
the Group has defined the following time horizons:

Short term

0-2 years

Medium term

Long term

2-10 years

10+ years

The key risks Spirent has identified are as follows:

Transitional risks
It is expected that there will likely be a large and radical 
change in global markets, with a drive to shift quickly towards 
renewables and away from fossil fuels, resulting in increased 
carbon taxes across all regions in the short and medium 
term. This may result in associated increased costs. Starting 
in the short term, costs are likely to increase by an immaterial 
amount due to higher investment requirements in low-carbon 
technology and expected additional carbon-related levies 
and we also expect additional administrative burden on the 
business, likely increasing the costs for resource to deliver 
and report. 

We have modelled the impact of carbon credits using a price 
per tonne CO2e of up to £250 and the impact is not material. 
Transitional risks are also unlikely to lead to any impairments 
or write offs. We expect to purchase carbon credits in the 
short- to medium-term in line with our commitment to 
achieve CarbonNeutral® Company certification, but expect 
energy efficiency and renewable energy to reduce the 
requirement for carbon credits as we progress towards 
net zero carbon in 2035. Over the course of 2023, the ESG 
Management Committee, with the help of an external adviser, 
is further developing and refining Spirent’s plan to reach net 
zero. Further development of this plan includes capturing 
the key activities and mitigating actions such as site strategy 
and consolidation, retrofitting, the sourcing of renewable 
energy, etc. to allow for a more detailed quantification of the 
cost impact to Spirent over the medium and long-term. The 
impact of our approach will be examined during 2023 having 
completed a full Scope 3 footprint calculation.

Physical risks
Acute
Considering the potential of increasing intensity and frequency 
of storms and concentrated rainfall events, and frequency of 
wildfires, we have assessed that these risks would possibly 
cause some disruption to operations. Wildfire risks are most 
relevant to our operations in Calabasas, CA and flooding in 
our principle contract manufacturer, based in Thailand.

In the medium to long term, risks include Spirent site damage 
to building and infrastructure, lost time and productivity and 
any associated increased cost of insurance.

STRATEGIC REPORTSustainability continued

Task Force on Climate-related 
Financial Disclosures (TCFD) 
continued

Physical risks continued
Acute continued
Additionally, a major supplier disruption event is a possible 
key risk, causing an outage for a period of time which we 
assess as causing possible delays to customer shipments 
and the timing of revenue recognition.

Spirent has mitigation plans for each of these physical 
risks identified, which have been developed as part of 
longstanding business continuity and disaster recovery plans. 
Spirent engineering centres are situated in various different 
locations allowing a level of flexibility and agility should 
one site become affected. We endeavour to dual source 
key components wherever possible. Additionally, the Group 
has appropriate business interruption insurance in place.

Chronic
Higher peak and average temperatures are likely to result 
in increased energy demand and cooling capacity required 
for lab and office environments. This could lead to increased 
capital expenditure to expand or upgrade cooling equipment 
across multiple Spirent sites. In addition, increased heatwaves 
and droughts could have an impact on the health of more 
vulnerable employees and their families possibly resulting 
in higher staff absence levels.

It is possible that the rise in average temperatures may reduce 
energy use through a reduction in heating. Additionally, there 
may be a market opportunity relating to the provision of 
emerging energy efficient Spirent products. 

We have identified a number of areas of opportunity. These 
include a reduction in costs and improved efficiency, especially 
from estates consolidation and automation within our labs. 
We also expect that a greater focus on climate change will 
increase our resilience from climate related weather events, 
both within our estate and across our supply chain.

We also recognise our role in supporting clients to develop new 
technology. We recognise that there may be opportunities for new 
use cases for our existing test solutions to support climate mitigation 
in particular in the area of lab automation and consolidation.

The Group is still exploring the opportunities that climate 
change presents and therefore they have not been 
incorporated into the modelling.

Scenario analysis
The impact of each of the risks identified above has been 
assessed, quantified and considered in two climate  
change-related scenarios:

•  aggressive mitigation – emissions halved by 2050, average 

temperature increase of 1.5°C; and

•  strong mitigation – emissions stabilised at half of today’s 

emissions by 2080, average temperature increase of 2.4°C.

These scenarios were selected as they would include the 
most aggressive policy responses (which are likely to have the 
greatest impact on our business in the next three to five years) 
and because we believe that aiming to limit climate change 
to 1.5°C still remains the right policy objective.

36

Spirent Communications plc Annual Report 2022

In terms of modelling horizon, we have considered the 
impacts over the short, medium and long term, and with 
regard to the occurrence of the risks identified and also in 
comparing with the horizons adopted by peers, the most 
appropriate time horizon to model is 15 years. The most 
recent strategic three-year plans have been extrapolated to 
form the base case long-term plans from which to sensitise, 
using growth rates and assumptions consistent with other 
forward-looking financial statement items (goodwill impairment, 
viability) and assumptions.

Given the modelling horizon, there is not likely to be a 
significant difference between the two scenarios in relation to 
our exposure to physical risks – a change of 1.5°C is expected 
by 2030 under all scenarios, with the same likelihood and 
distribution of extreme weather events and chronic changes 
in weather patterns and temperatures. The major differences 
appear between 2040 and 2080 which falls outside of the 
scope of our long-term plans and provides sufficient time for 
the business to adapt if required. In terms of transitional risk, 
we do expect a difference between the two scenarios, most 
notably in the size of increases to energy costs and the size 
of anticipated carbon tariffs across all regions.

Based on the modelling we have performed and given 
the significant financial headroom Spirent has, the relative 
magnitude of the impact the risks present, the mitigation plans, 
and the insurance cover in place, it is not anticipated that the 
climate-related risks identified will have a material impact in the 
short term. The longer-term impact on the organisation’s strategy 
and plans is currently being further assessed but initial analysis 
does not suggest a significant financial impact. Therefore, Spirent 
is considered resilient to climate change-related scenarios.

Metrics and targets
We monitor carbon emissions sources that fall within Scopes 1, 
2 and 3 and report our carbon emissions annually within the 
Annual Report and Sustainability Report.

We have set clear targets to source electricity from 100 per 
cent renewable sources, and work towards net zero carbon 
by 2035. We have targeted a 25 per cent reduction in our 
energy usage by 2025.

We have considered whether the existing metrics and targets 
support the ongoing assessment of climate-related risks and 
opportunities and have determined that no additional metrics 
or targets are required at this time. This is on the basis that the 
short-term financial impact is considered immaterial. We will 
continue to evaluate whether additional metrics and targets 
are required as part of our existing business strategy and risk 
management processes, in particular in relation to supply chain 
risks, as we further refine our longer-term strategy and plans.

Promote diversity and invest  
in people
We aim to take action on diversity. We will attract and develop 
talent and skills, and support long-term sustainable growth.

Diversity in talent acquisition
In 2022, we ran programmes to support more diverse hiring, 
provide more family-friendly benefits, and support early 
career development and leadership. We added Prairie View 
A&M University to our university network and created a 
talent acquisition video to drive diversity and early career 
recruitment with our partners. We also launched an employee 

STRATEGIC REPORTresource group to lead talent acquisition and mentoring 
initiatives with Morgan State University, Prairie View A&M 
University and the Society of Women Engineers.

through academic support partnerships, which include 
undergraduate, post graduate and post doctoral participants. 
We also welcomed two new industry fellows from universities. 

Enhanced family-friendly benefits
This year, we introduced a range of enhanced global family 
leave benefits to provide staff with additional flexibility and 
support greater equality in the workplace.

Early career development
Spirent’s early career programme offers a structured pathway into 
a career in technology through internships, apprenticeships 
and university sponsorships. Our early career pathway 
incorporates resources, tools and training for managers 
and early career staff to help young, talented people start 
a career in technology.

In 2022 we have expanded our programme globally, offering 
placements and internships across EMEA, North America 
and APAC. We engaged with 24 universities worldwide 

At 31 December 2022, our gender diversity was: 

Our 2021 cohort of young engineers in the UK completed the 
course in June 2022 when five new early career positions started.

Equality and diversity
The Group employs a diverse workforce and prides itself on 
providing equal opportunities for all. High value is placed on 
rewarding our people for their commitment, their integrity 
and their service. Our commitment to a fair and inclusive 
workplace is governed by our Business Ethics and HR Policies 
which ensure that no one is discriminated against, directly or 
indirectly, on the grounds of colour, race, ethnic and national 
origins, sexual orientation or gender, marital status, disability, 
religion or belief, being a part-time employee, or age.

The 2022 snapshot data shows a downturn by comparison 
to the previous year. We were ambitious in adding significant 
headcount in our UK sales team and UK business operations in 
late 2021 and early 2022. The hiring in that time period included 
a higher percentage of female employees than has historically 
been the case but they were not in comparable senior roles 
to the male hires. That hiring pattern skews the snapshot data 
in a negative way. Employees added late in 2021 were also 
not eligible to participate in our 2021 annual bonus, which 
also impacts the snapshot of the number of females receiving 
a bonus compared to male peers. The snapshot this year 
reflects our efforts to hire more female employees.

Business ethics and human rights
Spirent’s values and principles are set out in the Group’s 
Business Ethics Policy. These principles apply to all dealings 
with our customers, suppliers and other stakeholders, and 
are considered in pre-contract due diligence and monitored 
through ongoing supplier audits.

STRATEGIC REPORTISO 14001
We set a target to expand the coverage of formal environmental 
management systems and achieve ISO 14001 certification at 
one major engineering site by 2022 and all major sites by the 
end of 2025.

In 2022 we completed the implementation of our 
environmental management system at our LSA business, 
including our engineering sites in Plano, TX, Frederick, MD, 
and Littleton, MD.

Circular economy training
The design of our products significantly influences the 
environmental impact of our products across the whole 
lifecycle. We have seen significant improvements since 
implementing sustainability metrics in our product design 
process and to support further gains in this area, we set 
an objective to roll out training on circular economy for 
our engineers.

Having assessed a number of training courses but felt 
none met our requirements, in 2022 we developed our 
own bespoke circular economy training course. The training 
incorporates both an introduction to key aspects of theory 
and how it applies to Spirent’s product and design process 
specifically. This training has been piloted and, working with 
our Chief Technology Officer, we will run a hackathon in 2023 
to develop new design concepts and innovation opportunities 
to help deliver more sustainable products.

Vendor assessment and auditing
Vendors are required to abide by our Code of Conduct which 
sets out our expectations for environmental management, 
labour and human rights, health and safety, and business 
ethics. They are assessed using a detailed questionnaire.

Priority suppliers are audited by Spirent’s procurement 
team: 30 supplier audits were conducted in 2022, meeting 
the target we set. No material issues were identified. Three 
minor non-conformances were identified. More than 80 per 
cent of our hardware supply chain spend is from companies 
audited by us, our contract manufacturers, or through the 
RBA VAP audit programme. We have expanded our supplier 
ESG partnerships, working closely with CALNEX (a contract 
manufacturer) to conduct joint supplier audits and to improve 
packaging design; reducing material used and removing 
non-recyclable materials. We have also started working 
with smaller suppliers to provide support to improve their 
ESG management.

Sustainability continued

Promote diversity and invest  
in people continued

Business ethics and human rights continued
The Group has a zero-tolerance approach to all forms of 
bribery and corruption. As a UK registered company, Spirent

the Bribery Act 2010, in respect of its conduct both at home 
and abroad. In addition, we will uphold all laws relevant to 
countering bribery and corruption, including the US Foreign 
Corrupt Practices Act, as well as human rights protection, in all 
jurisdictions in which we operate.

Regular anti-bribery training is required to be taken by certain 
employees. New starters received training this year and all 
designated employees completed the training in 2022.

Health and safety
The Board has designated the CFO as the Board member 
responsible for health and safety within the Group and 
procedures are in place for incidents to be reported through 
the Audit Committee to the Board as necessary.

The health and safety risk profile for the Group remained low 
during 2022, with no reported accidents (2021 three). There 
were no reportable accidents under the RIDDOR Regulations 
or required hospitalisations during the year.

Training and skills
Spirent provides all its employees with a wide range of 
technical and business training opportunities. We manage 
training through personal development plans which are 
assessed by all managers and updated periodically.

STEM initiatives and community impact projects
Spirent actively encourages its employees to become STEM 
Ambassadors around the globe. 

We provide all our employees with volunteering time off 
to make a positive contribution to the communities in which

•  We launched Spirent Vantage, an innovative solution 

that dramatically simplifies and automates 5G service 
assurance for communications service providers (CSPs).

Deutsche Telekom 
Using IntOps to unlock 
5G’s full potential 

Challenge:
Unlike earlier generations of network upgrades, 5G expands 
the supplier ecosystem to embrace software-defined network 
functions that bring with them agility and innovation. But with 
this shift, industry leaders such as Deutsche Telekom (DT) and 
others recognised that the old ways of building, managing 
and upgrading networks must adapt to modern realities. 

Solution:
DT’s vision of a new strategy was built on the notion of 
highly automated environments with integrated testing to 
deliver on the true potential of both 5G and interconnected 
telecommunications systems. Reinventing how it runs 
its operational workflows, DT took ownership of both 
Integration and Operations - defined internally as IntOps 
- and collaborated with Spirent to create automated 
continuous testing (CT) at each stage of the pipeline, 
rather than creating additional pipeline stages for testing. 

Impact:
IntOps has been adopted by DT and is demonstrating 
practical benefits, while the shift towards its intrinsic methods 
is an emerging trend across the industry. The role for CT 
as defined by IntOps is also shifting in line with the needs 
for a more dynamic, agile and adaptive network to 
ensure the 5G transition to the next generation of services 
is better for all.

Lifecycle Service Assurance 
continued 

Strategy 
Our Lifecycle Service Assurance strategy is: 1) deliver a leading 
active assurance platform for 5G and next-generation service 
delivery and user experience assurance; 2) help service 
providers automate critical test activities, as the industry 
moves towards an always-on continuous test environment; 
3) leverage our product offerings, together with our deep 
test and assurance expertise, to deliver a new portfolio of 
outcome-driven service offerings. Three key attributes set 
Spirent apart in the Lifecycle Service Assurance market: 

•  Automation: Automation is finding broad adoption across 

the board at network equipment vendors, service providers, 
multi-system operators (MSOs) and enterprises, with the 
objective of improving agility and operational efficiency. 
Legacy testing and service assurance activities have been 
mostly manual, reactive and time consuming. As continuous 
integration and continuous delivery (CI/CD) development 
principles become mainstream with the adoption of 5G, 
automated testing and assurance are becoming essential 
to support the CI/CD model across all layers. Automation 
enables use cases such as new service activation, 
continuous monitoring and automated troubleshooting 
to be seamlessly integrated with network management 
systems, with a goal of establishing fully autonomous 
operations. Spirent is at the forefront of this journey.

•  Coverage: Spirent is the only vendor to offer both lab and 
live solutions as both a contiguous and continuous test 
offering. With the broadest coverage in the industry, from 
the user device into the radio access network, across the 
cloud and mobile backhaul, and into the mobile core, 
our solutions provide the broadest end-to-end visibility 
in the industry. The breadth and depth of our expertise 
and our portfolio enable us to quickly address net-new 
opportunities including O-RAN and next-generation 
fixed wireless access (FWA).

•  Analytics: It is one thing to provide data, and quite another 
to provide actionable insights using that data. We continue 
to advance machine learning and signature-based 
analysis that allow our customers to detect, isolate and 
eliminate potential service interruptions or degradations 
before subscribers are impacted. This in turn allows 
rapid reduction in mean-time-to-repair by alleviating 
the unnecessary escalations typically found in traditional 
operational support models. In 2022 we expanded our 
analytics coverage with a newly formed 5G benchmarking 
offering, giving service providers unique insights into what 
their customers will experience prior to market turn-up of 
live mobile networks.

What we test and assure 
Our Lifecycle Service Assurance offerings support the 
full lifecycle for any new technology roll-out. From pre-
production emulation and certification, to post-production 
troubleshooting, to automating a continuous test environment, 
we help our customers maximise the monetisation of any 
new technology. The following key areas were instrumental 
in growing pipeline and product sales in 2022, and offer 
continued expansion opportunities into 2023 and beyond: 

42

Spirent Communications plc Annual Report 2022

•  5G core: For both standalone and non-standalone flavours 
of 5G, Spirent provides continuous testing capability across 
the entire lifecycle for any initiative. Beginning with the 
network equipment manufacturer, through service provider 
deployments and enterprise service consumption, our 5G 
offering bridges the gaps traditionally found between the 
develop, deploy and operate phases of a new technology 
roll-out. Focus areas include 3GPP network function testing, 
and 5G network slice testing and assurance. In 2022 we 
enhanced our 5G Core Automation Platform with a new 
security automation package. 

•  Open RAN (O-RAN): 2022 marked a significant milestone 
in our O-RAN strategy as we delivered a solution for full 
wrap-around testing of the O-RAN Radio Unit (RU) and 
Distributed Unit (DU) functions, to be quickly followed by 
full end-to-end O-RAN test capability. With this solution, 
Spirent has positioned itself as the industry’s first vendor to 
deliver a single, fully integrated O-RAN offering, in contrast 
to competing approaches that attempt to bring together 
disparate products from previous generations of RAN 
test technologies.

•  Wi-Fi: Following the acquisition of octoScope in 2021, 
Spirent became the market leader in Wi-Fi test and 
certification. With the adoption of Wi-Fi 6E in full swing 
and Wi-Fi 7 in development, this is an attractive market 
unto itself. However, with world-leading expertise in both 
technologies, the convergence of Wi-Fi and 5G represents 
a unique opportunity for Spirent, as trends including IoT, 
Smart Cities, Industry 4.0 and private 5G networks drive 
technology convergence. In 2022 we addressed a growing 
need by introducing a very successful, industry-first Wi-Fi 
TaaS offering. 

•  Cloud (multi-cloud): With the introduction of 5G and cloud-
native infrastructure such as O-RAN, it is critical that service 
providers implement an automated, always-on approach 
to testing, troubleshooting and remediation of issues in 
real time as they occur. While introducing tremendous 
flexibility and extensibility, these infrastructures present 
unprecedented levels of complexity. With its cloud-native, 
fully virtualised implementation of automated test and 
troubleshooting capabilities, Spirent is well positioned 
to help our customers migrate their infrastructure and 
services to the cloud. 

Despite some purchasing delays 
due to the macro environment, 
we remain confident in our 
customers’ commitments to 
their 5G investments, and the 
complexity challenges they 
need to overcome represent an 
enduring driver for our business.

General Manager, Lifecycle Service Assurance, Spirent

STRATEGIC REPORTPerformance 
Lifecycle Service Assurance revenue increased to $264.5 million 
(2021 $261.6 million). We saw demand for next-generation 
automated test and assurance, in combination with new 
outcome-driven service offerings and growth in our Wi-Fi 
portfolio. We continued to expand our existing Test-as-a-
Service offerings, seeing success with our new Wi-Fi and 5G 
benchmarking capabilities. 

However due to current macroeconomic challenges, we 
experienced customer purchasing decision delays in the latter 
part of the year, particularly for our lab-based products. We 
anticipate these delays to be temporary, since the majority 
of 5G investment globally is already committed and  
non-discretionary. The number of operators investing in 5G 
standalone (SA) with a 5G core network is forecast to double 
by the end of 2023.

This had a direct adverse impact on revenue opportunities in 
the year and as a result Lifecycle Service Assurance adjusted 
operating profit decreased to $51.0 million (2021 $63.1 million).

Adjusted operating margin decreased to 19.3 per cent, 
from 24.1 per cent in 2021. 

Accomplishments 
•  Wi-Fi provided a good boost this year, partially offsetting 

5G investment delay headwinds, with growth across 
all regions.

•  We launched Spirent Vantage, an innovative solution 

designed to automate and greatly simplify 5G’s complex 
service assurance challenges, broadening our addressable 
market beyond the top-tier service providers targeted by 
our existing VisionWorks solution.

•  Spirent’s Vantage 5G Service Assurance product was a 

finalist in the 2022 Fierce Innovation Awards “Network Test 
& Measurement” category.

•  Our live assurance portfolio continued to see significant 
double-digit growth across all regions in support of 5G 
infrastructure as it moves from lab certification into live 
operations.

•  We won a large 5G core and cloud Test-as-a-Service deal 
at a leading service provider in India, playing a key role in 
enabling the customer’s 5G transformation.

Helping to deliver lab-to-live 
with Active Assurance

Challenge:
Having learned valuable lessons from its 4G service 
launch, a tier-one North American service provider 
wanted to develop a clear plan for assuring its 5G 
network and services before it launched. With an 
expectation of also providing performance-intensive 
services with differentiated SLAs using network slicing, 
the ability to assure 5G performance and troubleshoot 
efficiently was vital.

Solution:
Deciding that an active approach was required, with a 
major focus on 5G standalone core, the service provider 
selected Spirent for its deep expertise and leadership 
in active assurance. Working closely with various 
groups within the service provider’s organisation, 
Spirent was able to help identify how its active assurance 
technology could be deployed to benefit it. Spirent 
also deployed TaaS test platforms for lab validation 
and TaaS benchmarking services for field testing, as 
well as active assurance for live network assurance.

Impact:
Spirent now provides a full lab-to-live testing presence 
for the provider, with automation and consistency 
across the lifecycle, enabling their migration to a more 
agile and efficient CI/CD model.

Testing times for mission-critical 
aeronautics networks

Challenge:
A world leader in the design and manufacture of  
high-reliability connectivity solutions for aerospace, 
defence, space and industrial applications turned to 
Spirent for a time-sensitive networking (TSN) solution. 
The company needed to validate TSN conformance 
and performance of complex mission-critical TSN-based 
networks in aircraft, where interoperability is essential 
for complex systems that integrate components from 
different vendors.

Solution:
The conformance requirement is driven by the need 
to ensure that the different components share a 
common understanding. Once standard conformance 
is tested successfully, the systems are tested to ensure 
they meet their functional behaviour requirements, 
and their network performance values match the 
requirements defined by the applications they will 
support. Spirent’s solution comprised the much-trusted 
C50 appliance workhorse, along with a full TSN 
software bundle that included Spirent TestCenter to 
test functional performance, and Spirent TTworkbench 
for highly automated TSN conformance testing.

Impact:
Thanks to Spirent’s extensive coverage of TSN 
protocols, conformance testing and advanced 
one-armed TSN functional and performance 
testing, the Spirent team was able to exceed the 
customer’s expectations with an engagement that 
provided further indication of the growth of TSN in 
the transportation domain beyond automotive. 

STRATEGIC REPORTFinancial review

Good growth 
in a difficult 
environment 

Group overview
Momentum continued in 2022 against a backdrop of 
global economic challenges, supply chain constraints and 
cost inflation. Customers continue to invest in 5G-related 
infrastructure, devices and services, but the final quarter 
of 2022 saw some delays to customer investment decisions 
which was as a direct result of customer expenditure scrutiny 
as macroeconomic challenges prevail. Despite this, our 
operating model remains robust and we continue to invest 
in our leading technology portfolio and our people.

Orderbook grew 6.8 per cent to $288.1 million compared to 
$269.8 million in 2021, in spite of some orders being delayed 
into 2023. This followed orderbook growth of 18.1 per cent in 
2021 and resulted in a book to bill ratio of 103 (2021 111).

Revenue grew by 5.5 per cent to $607.5 million driven by 
strength in high-speed Ethernet demand and new product 
launches at Networks & Security. There was also growth 
in revenue at Lifecycle Service Assurance resulting from 
demand for next-generation automated test and assurance. 

As we predicted, gross margin was adversely impacted by 
the increased cost of supply chain costs in the main which 
we offset with good operating expenditure management.

The cost base continues to be managed effectively, with 
a rigorous focus on cost control and targeted investment 
in high-growth areas. In the face of inflationary pressures, 
adjusted operating costs were flat versus 2021. The Group 
commenced a strategic evaluation to reshape the business to 
maximise market opportunities by focusing on larger bundled 
solutions sales and service-led engagements that address our 
customers’ most pressing business challenges.

Adjusted operating profit grew 9.3 per cent to $129.5 million, 
from $118.5 million in 2021. Adjusted operating margin has 
increased by 0.7 percentage points to 21.3 per cent, from 
20.6 per cent last year.

 Adjusted operating profit as a percentage of revenue in the period.

STRATEGIC REPORTOther adjusting items were $3.6 million (2021 $4.5 million) as the R&D engineering plan continued in 2022 and the Group 
commenced a strategic evaluation of the organisation incurring some employee separation costs. 

Reported profit before tax was up by $11.0 million to $114.6 million (2021 $103.6 million).

The Group’s effective tax rate of 12.9 per cent has reduced from 2021 (14.4 per cent) due to an increased US foreign-derived 
intangible income (FDII) deduction and the recognition of deferred tax assets related to US state tax losses and tax credits. 
Adjusted basic earnings per share has increased by 13.7 per cent, up from 16.59 cents last year to 18.86 cents for 2022.

We secured the majority of defined benefit pension liabilities of $166.4 million (£137.5 million), through insurance buy-in with 
Pension Insurance Corporation (PIC), removing exposure to future investment, longevity, interest and inflation risks. 

We retain a strong balance sheet with closing cash of $209.6 million (2021 $174.8 million), following a disciplined focus on working 
capital management, resulting in a free cash flow of $103.8 million (2021 $91.9 million). 

As a result of the strong financial performance, we propose a 12 per cent increase to the full year dividend per share, from 
6.76 cents to 7.57 cents, and looking forward we maintain our progressive dividend policy ensuring that we sustain dividend 
cover of 2 to 2.5 times adjusted earnings.

Note on Alternative Performance Measures (APM)
The performance of the Group is assessed using a variety of performance measures, including APMs which are presented to 
provide users with additional financial information that is regularly reviewed by management. These APMs are not defined 
under IFRS and therefore may not be directly comparable with similarly identified measures used by other companies.

The APMs adopted by the Group are defined on pages 196 and 197. The APMs which relate to adjusted income statement lines 
are presented and reconciled to GAAP measures using a columnar approach on the face of the income statement and can be 
identified by the prefix ‘adjusted’ in the commentary. All APMs are clearly identified as such, with explanatory footnotes to the 
tables of financial information provided, and reconciled to reported GAAP measures in the Financial Review or Notes to the full 
year consolidated financial statements. The reported GAAP measures give the complete measure of financial performance.

Group revenue grew by $31.5 million to $607.5 million in 2022, an increase of 5.5 per cent over the prior year.

Revenue at Lifecycle Service Assurance was slightly up as demand from the continued global roll-out of 5G networks and growth 
in managed solutions and services was offset by previously communicated customer purchasing deferrals into 2023. We also saw 
growth in our Wi-Fi portfolio driven by demand for solutions and services enabled by our 2021 octoScope acquisition, and in other 
services offerings, including live 5G network benchmarking. We experienced further robust growth in the orderbook in 2022 as the 
value of multi-year deals continued to increase. 

The Networks & Security operating segment saw growth in revenue of 9.1 per cent on the back of market demand for 
increased network data capacity, and the release of important new solutions for high-speed Ethernet and application security 
test, reinforcing our position as market leader in this space. Positioning revenue also delivered progress with some key wins 
in Asia Pacific.

Total Group maintenance and support services revenue increased 12.6 per cent to $185.4 million (2021 $164.7 million).

Geographically, we saw growth in revenue in the Americas and Asia Pacific, notably in China and India at Networks & Security. 
As a percentage of total revenue the regions are similar compared to last year.

Spirent Communications plc Annual Report 2022

STRATEGIC REPORTDespite inflationary pressures, total Group adjusted operating costs of $307.6 million were held level compared to last year. 
The emphasis remained on strong financial management and a disciplined approach to our investment spend to drive our 
growth agenda. 

The overall investment in product development decreased year-on-year from $113.3 million to $111.3 million, representing 18.3 per 
cent of revenue (2021 19.6 per cent), driven by cost-saving initiatives as we transferred resource in lower-cost regions. We continued 
to focus on our high-growth areas and to maintain investment into our market-leading products. During the year, we invested in 
our Lifecycle Service Assurance solutions for next-generation service assurance and O-RAN.

We continued to invest in the sales organisation to support our revenue growth plans. Selling and marketing costs decreased by 
$1.8 million, from $140.7 million to $138.9 million, resulting from reduced sales commissions following some order softness from 
the deferral of investments into 2023 by some customers. 

Administration costs reflect investment into our support functions and infrastructure to sustain our growth agenda, increasing 
compliance requirements, as well as an inflationary increases. 

We have continued to invest in our world-class employees, enhancing our family-friendly benefits and working to support 
employee welfare, which has contributed to an employee retention rate significantly higher than the industry average.

Notes
1.  Before acquired intangible asset amortisation, share-based payment and other adjusting items amounting to $16.8 million in total (2021 $14.3 million).
2.  Adjusted operating profit as a percentage of revenue in the period.

Adjusted operating profit increased by $11.0 million or 9.3 per cent to $129.5 million in 2022, compared with $118.5 million in 2021. 
Adjusted operating margin increased by 0.7 percentage points to 21.3 per cent, from 20.6 per cent in 2021.

Reported operating profit was up by $8.5 million or 8.2 per cent to $112.7 million (2021 $104.2 million). Total adjusting items were 
$16.8 million in 2022, compared to $14.3 million in 2021, mainly due to an increase in the share-based payment expense due 
to an expansion of employee share schemes. 

Acquired intangible asset amortisation and share-based payment
The acquired intangible asset amortisation charge has increased slightly over the prior year due to a full year impact of the 
amortisation of the intangible assets recognised on the acquisition of octoScope from March 2021, with a charge of $4.7 million 
incurred in 2022 (2021 $4.2 million).

Share-based payment has increased to $8.9 million in 2022 (2021 $6.2 million), of which $8.5 million (2021 $5.6 million) has 
been treated as an adjusting item. The increase reflects the incremental cost associated with new awards and the expansion 
of employee share schemes. 

Spirent Communications plc Annual Report 2022

STRATEGIC REPORT 
Financial review continued

Other adjusting items 
Costs of $3.6 million have been charged to other adjusting items in 2022, mainly as a direct result of the continuation of the global 
R&D engineering facility plan which began in 2021 and will conclude in 2023. Costs amounting to $1.5 million (2021 $1.2 million) 
were incurred in 2022 comprising retention payments and facility and team set-up costs. The plan has delivered material cost 
savings particularly for our Networks & Security division. 

The Group also commenced a strategic evaluation in 2022, which led to employee separation costs of $1.3 million. This programme 
includes a number of initiatives designed to reshape the business to maximise market opportunities by focusing on solution sales 
and larger bundled solutions to customers. These include enhancement of the leadership team to include some important new 
roles such as a Chief Information Officer, a Chief Marketing Officer and development of our sales and marketing organisation 
whilst driving cost efficiency across the cost base. This programme has anticipated costs of $3-4 million in 2023.

Currency impact
The Group’s revenue and costs are primarily denominated in US Dollars or US Dollar-linked currencies. Currency exposures 
arise from trading transactions undertaken by the Group in foreign currencies and on the retranslation of the operating results 
and net assets of overseas subsidiaries.

The Group’s income statement includes a foreign exchange gain, included in administration costs, of $0.2 million 
(2021 $0.8 million loss) arising from transacting in foreign currencies, primarily US Dollars in the United Kingdom, 
and the translation of foreign currency cash balances.

Forward foreign currency exchange contracts are entered into to manage the exposure arising from transacting in currencies 
other than US Dollars.

Although the most significant currency exposure arises in relation to movements in Pound Sterling against the US Dollar, there 
are other less significant currency exposures, notably the Euro and Chinese Yuan.

Finance income and costs
Interest income of $2.1 million was earned from cash on deposit (2021 $0.3 million) and $0.8 million (2021 $0.3 million) of interest 
income was recognised in relation to the UK defined benefit pension plans. The growth in bank interest received year-on-year 
reflects the increase in US Dollar and Sterling interest rates. Surplus funds are held principally in the United Kingdom and United 
States on short-term or overnight deposits and earn market rates of interest.

Finance costs in 2022 were $1.0 million (2021 $1.2 million), relating to interest on lease liabilities (2021 $1.1 million).

Tax
The adjusted effective tax rate, being the adjusted tax charge expressed as a percentage of adjusted profit before tax, shown 
on the face of the consolidated income statement, was 12.9 per cent in 2022, compared with 14.4 per cent in 2021.

Spirent’s effective tax rate continues to benefit from the United Kingdom Patent Box Scheme, the United States R&D Tax Credit, 
the US foreign-derived intangible income deduction, and a current year recognition of deferred tax assets in the United States.

Going forward it is anticipated that Spirent’s effective tax rate will slightly rise over time, due to the geographical mix of profits, 
and 2023 will likely be around 15 per cent if statutory tax rates do not materially change. As a large proportion of the Group’s 
profit is generated in the United States, the effective tax rate is exposed to changes in US tax legislation. The new administration 
has indicated its desire to increase corporate tax rates and other countries may also be considering raising their corporate 
tax rates. The UK corporation tax rate will be increased to 25 per cent, effective from 1 April 2023. As a result, we will be closely 
monitoring all proposed corporate tax rates and other tax legislative changes for their impact on the Group’s effective tax rate.

Earnings per share
Adjusted basic earnings per share was up 13.7 per cent to 18.86 cents (2021 16.59 cents). Basic earnings per share was 16.46 cents 
(2021 14.67 cents). There were 607.0 million (2021 608.2 million) weighted average Ordinary Shares in issue. See note 11 of Notes 
to the full year consolidated financial statements on page 151 for the calculation of earnings per share.

Treasury management
The key objective of the Group’s treasury function is to manage the financial risks of the business and to ensure that sufficient 
liquidity is available for the Group. All treasury activity operates within a formal control framework. The Board has approved 
treasury policies and guidelines and periodically reviews treasury activities. Additionally, it is the Group’s policy that speculative 
treasury transactions are expressly forbidden.

Spirent’s financial risk management objectives and policies and its exposure to risks are discussed in note 28 of Notes to the full 
year consolidated financial statements.

STRATEGIC REPORTFinancing and cash flow
Free cash flow increased year-on-year coming in at $103.8 million, compared to $91.9 million in 2021, resulting in a free cash flow 
conversion which represented 91 per cent of adjusted earnings (2021 91 per cent). 

Higher adjusted operating profit was augmented by effective working capital management resulting in a net working capital 
outflow of $2.9 million, excluding the impact of movement in provisions; this compares to a working capital outflow of $10.1 million 
in the prior year. 

Closing days sales outstanding of 60 remained consistent with the prior year, reflecting continued strong collections, but with 
lower revenue in the final quarter of 2022 compared to 2021, closing receivables were down resulting in a small cash inflow 
from receivables. Inventories increased by $14 million (2021 $2 million) in 2022 driven by the business need to hold higher levels 
of materials in order to navigate supply chain challenges and fulfil customer demand.

Free cash flow is set out below:

Free cash flow includes a net cash outflow in respect of other adjusting items charged in 2021 and 2022 of $2.6 million 
(2021 $4.0 million in respect of other adjusting items charged in 2020 and 2021).

Tax payments made in the year increased to $22.8 million (2021 $10.0 million) due to R&D cost capitalisation rules in the US coming 
into effect on 1 January 2022. The new rules require that, for tax purposes, product development costs are deferred and unwound 
over a number of years rather than deducted in the year in which they are incurred. This results in a timing difference only so does 
not directly impact the Group’s effective tax rate.

Net capital expenditure of $8.2 million was slightly down on the prior year (2021 $9.8 million). Capital expenditure in the period was 
predominantly incurred on demonstration and test equipment. The one-off employer contribution to the UK pension scheme in the 
prior year arose in relation to an agreement to further fund the scheme when we also made a return to shareholders. 

In 2022, the final dividend for 2021 and an interim dividend for 2022, totalling $39.9 million, were paid. This compared to total 
dividends of $83.6 million paid in 2021, which also included payment of a special dividend of $45.6 million. In addition, 7.1 million 
shares were purchased and placed into the Employee Share Ownership Trust at a cost of $22.9 million (2021 3.9 million shares at 
a cost of $15.1 million).

Following these payments, cash and cash equivalents closed at $209.6 million at 31 December 2022, compared with $174.8 million 
at 31 December 2021. There continues to be no debt outside of lease liabilities.

STRATEGIC REPORTOverall, liabilities of $240.1 million are broadly flat at 
31 December 2022 (2021 $243.8 million). A year-on-year 
increase in trade payables of $20.7 million due to timing 
and a disciplined focus on working capital and supply chain 
management has been partially offset by reduced accruals 
in 2022 relating to sales commissions and employee bonuses.

Liquidity and dividend policy
The Board’s intention is to maintain a cash positive balance 
sheet over the medium to long term. This should allow 
the Company to maintain a strong capital position in the 
face of business risks, trading fluctuations and working 
capital demands.

The strong cash generation of the Group allows continued 
investment into R&D to maintain our market-leading positions 
and inorganic investments where opportunities support growth 
plans. If and when it is considered appropriate, the Company 
may take on modest gearing to fund inorganic investments.

The Board will regularly review the Company’s balance 
sheet in light of current and expected trading performance 
and cash generation, working capital requirements and 
expected organic and inorganic investments. To the extent 
the Company has excess cash, it will consider returning such 
cash to shareholders. The Board will consider from time to 
time the appropriate mechanism for returning surplus cash 
to shareholders.

The Board has implemented a progressive dividend 
policy maintaining cover in the range of 2 to 2.5 times 
adjusted earnings.

Dividend
The Board is recommending the payment of a final dividend 
for 2022 of 4.94 cents (4.12 pence) per share which, together 
with the interim dividend of 2.63 cents (2.16 pence) per share 
paid in September 2022, brings the full year dividend to 
7.57 cents (6.28 pence) per share, a dividend cover of 2.5 times 
adjusted earnings. This is a 12 per cent increase compared to 
the full year dividend for 2021. In Sterling terms this represents 
an increase of 24 per cent.

Defined benefit pension plans
The Group operates two funded defined benefit pension 
plans in the United Kingdom, both of which are closed to 
new entrants.

As the plans near maturity the Company has sought to protect 
the balance sheet from further risk of market movements 
affecting the valuation of pension liabilities. So in October 2022, 
the Trustees, with the Company’s support, purchased a bulk 
annuity insurance policy from specialist UK insurer Pension 
Insurance Corporation (PIC), in respect of the largest plan, the 
Staff Plan. The premium was met from the plan’s assets and 
sufficient assets remain to meet the plan’s ongoing costs. This 
insurance policy funds the plan each month exactly matching 
the plan’s benefit payments to members, removing investment 
and inflation risk as well as longevity and other demographic 
risks. Following the purchase of the bulk annuity insurance 
policy, the Group does not expect to make any further cash 
contributions to this plan. 

The accounting valuation of the funded defined benefit 
pension plans at 31 December 2022 gave rise to a net surplus 
of $8.0 million, compared with a net surplus of $37.8 million at 
31 December 2021. The reduction in net surplus over the year 
is mainly due to a net actuarial loss of $29.0 million (2021 gain 
of $13.5 million) arising due to a remeasurement loss on plan 
assets and the bulk annuity insurance policy purchase, partly 
offset by contributions paid to the plans in the year of $1.1 
million (2021 $6.7 million) and an actuarial gain on the plan 
obligations arising due to an increase in the discount rate.

Additionally, there is a liability for an unfunded plan of 
$0.5 million (31 December 2021 $0.7 million).

The Group also operates a deferred compensation plan for 
employees in the United States. As at 31 December 2022, the 
deferred compensation plan deficit amounted to $6.9 million 
(2021 $6.6 million). The key financial assumptions include a 
discount rate used to discount plan liabilities of 5.2 per cent 
(2021 2.6 per cent) and an expected investment yield of 
9.5 per cent (2021 6.4 per cent).

Balance sheet
The consolidated balance sheet is set out on page 128.

Overall, net assets have increased by $17.7 million to 
$465.2 million at 31 December 2022, from $447.5 million 
at 31 December 2021. 

Non-current assets have decreased by $30.9 million due to 
the pension buy-in which has resulted in a reduction in the 
fair value of defined benefit pension plan assets held in the 
UK Staff Plan. 

Cash and cash equivalents have increased by $34.8 million 
within current assets to $209.6 million (2021 $174.8 million) 
following the robust trading performance, payment of 
dividends amounting to $39.9 million (2021 $83.6 million) 
and purchases of shares to satisfy employee awards of 
$22.9 million (2021 $15.1 million).

STRATEGIC REPORTPrincipal risks and uncertainties

Like all businesses, Spirent is exposed to a number of risks and 
uncertainties. These risks may arise from internal factors, but 
some will be a result of external factors over which the Group 
has little or no direct control. It is the effective management of 
these risks that supports Spirent in delivering on its strategic 
objectives, safeguards the Group’s assets and, over time, will 
enhance shareholder value.

The process to identify and manage the principal risks and 
uncertainties of the Group is an integral component of the 
internal control system.

The risk assessment process starts in the businesses, where 
risk registers are maintained as part of the normal operating 
and control procedures, and is facilitated by the Head of 
Risk & Internal Audit. Each business identifies its key risks and 
mitigating factors and nominates a risk owner. The impact 
and the likelihood of occurrence of each risk is ranked, which 
assists the Group Executive Committee in assessing the likely 
impact in aggregate of each risk to the Group as a whole. 
The individual businesses are required to update their risk 
registers regularly to reflect new or emerging risks as they 
are identified to keep them up to date.

The approach includes a process to identify, clarify and 
communicate emerging risks for Board discussion and 
assessment, along with agreed mitigating action plans.

It is not possible to identify every risk that could affect the 
business and the actions described below to mitigate those 
risks cannot provide absolute assurance that the risk will 
not occur or adversely affect the operating or financial 
performance of the Group.

The Board has classified the principal risks by the impact the 
risk would be expected to have on the Group should it occur, 
and the anticipated likelihood that risk may occur using the 
following classifications:

Risk

Impact

Likelihood of occurrence

Impact

High

Medium

Low

Likely

Possible

Unlikely

The Board takes the view that a high-impact risk could lead to 
a 10 per cent or more reduction in revenue, a medium-impact 
risk a 5 to 10 per cent reduction in revenue and a low-impact 
risk a reduction of up to 5 per cent in revenue.

The Audit Committee reviews and monitors the Group’s risk 
processes and reports to the Board on their effectiveness. 
Risk is considered by the Audit Committee at least twice 
each year, at which time the risk registers are reviewed. 
The Audit Committee challenges and debates the risks with 
reference to risk tolerance and appetite, as set by the Board. 
Progress made and any further actions to be taken regarding 
mitigation plans, as well as any changes to the risk profile, 
are discussed.

Current topical risks, uncertainties and emerging risks
Topical risks and uncertainties along with emerging risks are 
covered in detail in the table of principal risks and uncertainties, 
but some of the more pertinent ones are described below.

Macroeconomic uncertainty
Spirent is a global business exposed to current world 
economic conditions over which it has no control. Global 
market economic conditions have been impacting some of 
our customers, resulting in delays to their investment decisions. 

War in Ukraine
The organisation has negligible activities within Ukraine and 
Russia and, therefore, it is expected to continue to have an 
immaterial direct financial impact on the Group unless it 
escalates and broadens further.

US/China trade and sanctions
The geopolitical landscape is turbulent with continuing 
US/China trade challenges. We have navigated regulatory 
changes throughout the year and continue to work closely 
with our customers and regulators. We make sales across a 
broad range of customers in China. Changes to existing US 
regulations to embargoed customers may impact our ability 
to supply affected customers in both the short and medium term. 
A conflict between Taiwan and the Chinese military could lead 
to a global recession and have an impact on the global supply 
of Taiwan’s microchips which the organisation is currently 
heavily reliant upon. We maintain a watching brief as legislative 
requirements and these geopolitical tensions continue to evolve.

STRATEGIC REPORTPrincipal risks and uncertainties continued

The Board has sought to frame its risk appetite in terms of 
the markets and technologies in which it is prepared to make 
significant investments, and those in which it would expect its 
scale of investment to be more modest. Except where very 
attractive opportunities were to present themselves to achieve 
greater scale in well understood markets, which would 
be inherently cash generative, the Board would expect to 
maintain a net cash position.

Management, together with members of the Board, 
considered which of the principal risks, either alone or 
in combination, might threaten the Group’s viability. The 
expected aggregate impact of the principal risks were 
modelled based on historical trends experienced across 
the Group. A severe but plausible combination of those risks 
was considered for the purposes of determining the revenue 
and free cash flow scenarios that should be stress tested via 
financial modelling.

A number of scenarios that encompass the principal risks and 
uncertainties were modelled over the three-year period, using 
the Group’s strategic three-year plan as a basis, and are set 
out in the table below. The analysis also included a reverse 
stress test scenario to illustrate the revenue reduction in the 
12 months following approval of the financial statements that 
would lead to the Group ceasing to be a going concern.

The impacts arising from the principal risks relating to 
employee skill base and acquisitions were not modelled as 
they arise as a result of specific events or transactions, the 
financial effects are less extreme than other risks or they 
would be expected to take longer to materialise.

The analysis included assumptions in relation to the ability of 
the Group to take realistic and successful mitigating actions 
to avoid or reduce the impact or occurrence of the underlying 
risks, including the ability to make significant reductions in 
its operating costs. In doing so an appropriate and realistic 
adjustment was made for the cost of taking those actions.

In performing the Viability Statement modelling the Board 
took into consideration the Group’s healthy cash balance 
of $209.6 million at 31 December 2022 and the ability of the 
Group to continue to generate positive free cash flow even 
in stressed scenarios, as has historically been the case.

Current topical risks, uncertainties and emerging 
risks continued
Task Force on Climate-related Financial Disclosures (TCFD)
We have undertaken TCFD-aligned scenario analyses, which 
involved senior management, to assess our exposure to 
climate-related physical and transition risks. This workstream 
is overseen by an Executive Director-led management 
committee that has been established to consider ESG 
matters including climate-related risks and opportunities, 
with updates reported regularly to the Audit Committee and 
the Board. More details can be found on pages 32 and 36.

From a transitional risk perspective, it is expected that there 
will likely be a shift quickly towards renewables and away 
from fossil fuels, resulting in increased carbon taxes across 
all regions in the short and medium term. This may result in 
associated increased costs; however, we do not estimate the 
impact to be material to Spirent.

From a physical risk perspective, the potential of extreme 
weather events has been considered and could cause some 
disruption to our operations or those of our key suppliers. 
Spirent has mitigation plans for each of these physical risks 
identified, that have been developed as part of longstanding 
business continuity and disaster recovery plans.

See pages 32 to 36 for further detail of our approach 
to environmental sustainability and climate change.

Supply chain
Supply chain issues have been experienced around the world, 
particularly with respect to the supply of semi-conductors, 
in 2022 due to COVID-19, the ongoing war in Ukraine, 
macroeconomic issues, and a number of other localised 
factors that are expected to continue in the medium term. 
There has been no material impact on our ability to deliver 
goods and services to customers. However, the impact of the 
component shortages has meant that we are experiencing 
longer lead times, supply chain cost increases and supply 
constraints, and there has been some disruption to the 
delivery timelines of hardware to our customers. This is 
causing us to hold more inventory, make longer-term 
commitments to suppliers and re-engineer some products to 
use more readily available components. We do now see some 
easing of supply chain challenges.

We continue to monitor any effect from these disruptions on 
the sourcing of components and the effect that this may have 
on our ability to manufacture hardware and deliver product 
to our customers on a timely basis. 

Risk appetite and developing the long-term 
Viability Statement 
The UK Corporate Governance Code requires the Board to 
explain how it has assessed the prospects of the Group and 
state whether it has a reasonable expectation that the Group 
can continue to operate and meet its liabilities, taking into 
account its current position and principal risks.

The Board has determined that a three-year period should 
be used when assessing viability, as explained on page 114 of 
this Annual Report.

56

Spirent Communications plc Annual Report 2022

STRATEGIC REPORTThe Board reviewed and discussed with management:

•  the process undertaken by management to decide 

which scenarios to stress test;

•  the results of the stress testing performed, including 
an illustration of the reduction in revenue and cash 
generation and consequently the availability of cash 
to fund operations; and

•  the ability of management to successfully take the 

mitigating actions identified.

Based on the results of this analysis, the Directors have 
a reasonable expectation that the Group will be able to 
continue in operation and meet its liabilities as they fall due 
over the three-year period. The Viability Statement is set out 
in the Directors’ Report on page 114.

A – Macroeconomic change

Spirent is a global business exposed to current world 
economic conditions and political and trade embargo 
uncertainties over which it has no control. 

We have navigated regulatory changes throughout the 
year and continue to work closely with our customers. 
Trade compliance issues continue to remain a focus, 
particularly with China.

The business is also exposed to government spending 
priorities, principally in the United States.

The COVID-19 crisis, the war in Ukraine, inflationary 
pressures, and rises in interest rates by major central 
banks have combined to create uncertainty to current 
world economic conditions and government spending 
priorities. The Group continues to monitor the impact 
to the global economy and possibility of a prolonged 
recession in the organisation’s key markets.

Potential impact
Deterioration in economic conditions and a change to the 
terms of conventional international trade and embargoing 
of specific customers may lead to a reduction in the level 
of demand for Spirent’s products and services and cause 
customers to delay their purchasing decisions.

Mitigating actions
The Group closely monitors both market and geographic 
trends in order to respond to changes in demand and be 
in a position to take timely actions to protect profitability 
where possible. 

B – Technology change

Spirent sells complex solutions in industries that can be 
subject to rapid and somewhat cyclical technological 
changes. Testing new technologies drives our business, 
but the opportunity also brings high risk since keeping at 
the forefront of these key future technologies is critical to 
our success and to ensuring that we remain competitive 
in our markets.

It is critical that our product development investment is 
directed at the right areas in order to deliver the solutions 
that our customers need when they need them.

Spirent’s success is dependent in part on proprietary 
technology which may be infringed by others.

Open-source tools become more prevalent providing 
some of the functionality of our products.

Due to COVID-19, there is an increased risk that 
technology changes may take longer to occur.

Potential impact
If product development investment does not keep pace with 
the speed of change in technologies, or if it is not directed 
at the right key areas, our competitive position and financial 
performance will suffer.

If Spirent’s solutions take longer to develop than anticipated 
or longer to develop than our competitors, then our 
competitive position and financial performance will 
also suffer.

Changes in technologies may lead to a short-term pause 
by our customers investing in our solutions.

Intellectual property claims can result in significant defence 
costs and may affect Spirent’s ability to market its products.

Customers may choose to use open-source tools instead 
of some Spirent products to meet part of their testing needs.

Mitigating actions
All Spirent’s businesses work very closely with customers and 
remain focused on their requirements.

Each business makes investment decisions specifically related 
to its solutions portfolio based on market needs.

Spirent continues to focus its investment into areas that 
offer the most potential for sustainable earnings growth. In 
2022 the product development investment was $111.3 million 
(2021 $113.3 million) as we find new ways of investing at 
lower cost.

In addition, Spirent has a large number of geographically 
diverse customers, which may mitigate the impact of issues 
in any one area.

Spirent has active intellectual property protection 
programmes in place to obtain appropriate protection 
in a cost-effective manner.

STRATEGIC REPORTPrincipal risks and uncertainties continued

C – Business continuity

Operational risks are present in the Group’s businesses, 
including the risk of failed internal and external processes 
and systems, human error, and external events, such as 
a natural disaster, climate change, a global pandemic 
or cybersecurity attacks. For example, a significant 
portion of our operations are located in California which 
has in the past experienced natural disasters, including 
earthquakes and wildfires.

Our TCFD-related analysis has considered the potential 
of increasing intensity and frequency of storms and 
concentrated rainfall events, and frequency of wildfires, 
and we have assessed that these risks would possibly 
cause some disruption to operations. The understanding 
of climate change-related risks is incorporated into the 
risk management framework.

The Group has therefore taken steps to manage 
the increase to business continuity risk, including 
invoking business continuity plans in each location, 
closely monitoring the impact to the supply chain with 
additional inventory procured on key components 
and by adding alternate suppliers, making last time 
buys as necessary, and by boosting the global Spirent 
information technology systems to enable the workforce 
to work remotely.

Contract manufacturers are used for a substantial 
amount of Spirent’s products and have experienced 
cost increases, end of life notices, lead time and delivery 
challenges with semi-conductors, leading to some 
shortages and increased costs during 2022. Spirent’s 
major contract manufacturer is located in Thailand.

The incidence of cybercrime continues to rise. Spirent is 
dependent on its information technology systems for both 
internal and external communications, maintaining our 
reputation as well as for day-to-day operations.

Potential impact
A significant natural disaster or global pandemic could disrupt 
the Group’s ability to conduct business and adversely impact 
revenue and operating results.

Higher peak and average temperatures could lead to 
increased capital expenditure to expand or upgrade cooling 
equipment across multiple Spirent sites.

The shift towards renewables and away from fossil fuels 
may result in associated increased costs. Starting in the short 
term, energy costs are likely to continue to increase due to 
higher investment requirements in low-carbon technology 
and expected additional carbon-related levies. We also 
expect additional administrative burden on the business, likely 
increasing the costs for resource to deliver and report. We do 
not estimate the impact to be material to Spirent.

In the medium to long term, our TCFD climate-related 
analysis has highlighted the risks of site damage to building 
and infrastructure, lost time and productivity and any associated 
increased cost of insurance. Additionally, a major supplier 
disruption event is a possible key risk, causing an outage for 
a period of time which we assess as causing possible delays 
to customer shipments and the timing of revenue recognition. 
Disruption, financial problems of contract manufacturers or 
limitations in their manufacturing capacity could limit supply 
and/or increase cost.

The ongoing semi-conductor supply chain shortage could 
lead to further disruption to the delivery of hardware to 
customers and further supply chain cost increases in 2023.

Failed internal and external processes, systems or human 
error could lead to compliance issues.

If a cyberattack were to be successful it could result in loss 
of data, reputation and confidential information as well as 
damage to Spirent’s intellectual property, causing major 
disruption to the business. Any security vulnerabilities in our 
products could also adversely impact our customers. There 
would also be a potential impact on Spirent’s credibility in 
the security market.

Mitigating actions
An important component of Spirent’s corporate governance is 
its risk management strategy. IT disaster recovery plans are in 
place for all core business systems and ensure that the wider 
operations are all fully covered. In 2022, we performed the 
annual refresh and test of the Group Business Continuity and 
Disaster Recovery Policy and Procedure.

Spirent has mitigation plans for each of the TCFD physical 
risks identified, that have been developed as part of 
longstanding business continuity and disaster recovery 
plans. Spirent engineering centres are situated across the 
globe allowing flexibility and agility should one site become 
affected. Where possible we have second source component 
supply to assist with the mitigation of interruptions in supply 
and regular meetings are held with contract manufacturers. 
In addition, the Group’s largest manufacturing subcontractor 
has multiple worldwide sites and comprehensive business 
continuity plans.

The Group has appropriate business interruption 
insurance in place.

We are working closely with our contract manufacturers 
and are in frequent direct consultation with key component 
suppliers worldwide to mitigate the impact of the ongoing 
semi-conductor supply chain challenges. The situation is 
dynamic and we will take appropriate action to mitigate 
the supply chain risk including the careful management 
of planning and fulfilment.

During 2022, we continued with a programme of work 
to enhance processes and procedures in the area of 
cybersecurity. Third party providers are used in both the 
testing and monitoring of our security profile. 

58

Spirent Communications plc Annual Report 2022

STRATEGIC REPORTD – Customer dependence/customer 
investment plan

The Group sells its products and services to a wide 
range of companies and continually seeks to expand its 
customer base. In 2022, no one customer accounted for 
more than 10 per cent of Group revenue, although the top 
ten customers represented 36 per cent of Group revenue 
(2021 38 per cent).

In some of our markets certain customers have a 
dominant market share, which makes doing business with 
these customers and their suppliers critical to the success 
of our business.

In addition, many of the companies with which we do 
business are some of the largest global telecommunications 
corporations. Therefore meeting our development 
obligations, producing high-quality products and being 
on time are vital to Spirent’s reputation and success.

Changes in our major customers’ priorities in technology 
investments can also have a significant impact on 
their spending on Spirent products and on those in 
the customers’ supply chain.

The industry continues to experience consolidation which 
does disrupt the spending patterns of affected customers.

As a result of the current economic uncertainty, customer 
spending patterns remain uncertain, particularly for lab and 
government markets. The Group has taken steps to evolve the 
sales team in order to strengthen relationships with customers.

Potential impact
Loss of one or more of Spirent’s major customers could have 
a significant impact on Spirent’s financial results.

Spend on Spirent’s products is often capital in nature and so 
customer spend can fluctuate significantly from year-to-year.

Significant failings in either quality or being able to deliver in 
the appropriate timescale could cause long-lasting damage 
to Spirent’s reputation and relationships.

Over recent years there has been significant consolidation in 
our customer base amongst service providers and network 
equipment manufacturers. This trend continues and often results 
in delays in spending, thereby reducing demand for Spirent’s 
solutions and services. It also reduces the potential number of 
customers to which those solutions and services could be sold.

Changes in our customers’ technology investments can 
result in reduced spending on our existing solutions before 
customers and those in the customers’ supply chains increase 
spending on new technologies.

Mitigating actions
Strong customer relationships are critical to Spirent. We aim 
to provide innovative solutions which meet customers’ needs 
and we place great emphasis on providing professional 
service and support.

One of the Group’s strategic objectives is to invest in 
deepening our customer relationships and our key account 
management initiatives assist to ensure robust relationships 
with our largest customers. We place engineers on site with 
our customers and undertake site surveys of intended plans 
for the use of test solutions in their business.

We seek to establish thought leadership in our industry 
through participation in standards bodies and industry 
forums, which in turn creates additional links with customers. 
Our approach is to play a key part in the wider supply chain 
to our key service provider customers by aligning with early 
adopters of technology.

We also seek to broaden our customer base to mitigate 
customer concentration risk, investing in digital marketing, 
inside sales and field sales to expand the number of new 
customers that we win.

E – Competition

Spirent operates in a range of highly competitive niche 
markets which experience rapid technological change. 
In order to compete effectively, it is necessary to establish 
and maintain technological differentiation in our solutions.

The Group faces competition from new market start-ups as 
well as more established and well-resourced companies.

Industry consolidation amongst our direct competitors 
may bring about a shift in competitive advantage.

Potential impact
Actions by competitors and increased competition can bring 
about pressure on Spirent’s gross margin. These factors could 
also affect Spirent’s competitive position, thereby reducing 
revenue and consequently affecting financial results.

Consolidation continues within our sector. The consolidation 
of competitors may bring opportunities for Spirent but can 
also change the competitive landscape as competitors are 
able to leverage product capabilities or sales channels.

Mitigating actions
The Group’s broad solution portfolio, market-leading 
capabilities and customer focus continue to address this risk.

Spirent aims to maintain market-leading positions through 
significant investment in the development of differentiated 
products. We also seek opportunities for attractive inorganic 
investments that can strengthen our competitive advantage.

Competitor activity is closely monitored with a view to 
maintaining clear differentiation based on Spirent’s products, 
services and global reach. 

Spirent Communications plc Annual Report 2022

STRATEGIC REPORTPrincipal risks and uncertainties continued

F – Acquisitions

G – Employee skill base

A key emerging element of Spirent’s strategy is to develop 
new capabilities and technologies, and to expand our 
addressable markets, sometimes through acquisition.

Integration of acquisitions can be a complex process 
and the results expected from acquisitions may not be 
achieved due to problems encountered in integration, 
changes in market conditions, the rate of adoption of new 
technologies, or sometimes deficiencies arising in the due 
diligence processes.

Potential impact
Underperformance by acquisitions will impact the Group’s 
results and may lead to impairment of goodwill and/or 
intangible assets.

Mitigating actions
Rigorous strategic and financial evaluations of all acquisition 
opportunities are carried out. Detailed financial and 
commercial due diligence is performed. The Board will 
only authorise transactions after all due diligence has been 
successfully completed and where the financial hurdles are 
within the agreed guidelines.

Employees are crucial to the success of our business. 
Attracting and retaining highly qualified and skilled 
employees is essential to enable the Group to deliver 
on its strategy and to the success of the business.

Potential impact
Intense competition for personnel is faced from other 
companies and organisations and the loss of key employees, 
the failure to attract and retain other highly skilled employees, 
or the failure to adequately plan for succession may impair 
Spirent’s ability to run and expand the business effectively.

Mitigating actions
Investing in people is at the core of the Group’s strategy. 
The aim is to find, keep and engage the highest calibre 
of employees and encourage their contribution and 
development. An environment that fosters innovation and 
collaboration is critical to Spirent’s success, as is ensuring 
incentive plans are competitive.

We have refined our employee value proposition and 
continue to make Spirent a more inclusive, diverse and 
engaging place to work to attract and retain talent.

Integration plans and processes are carefully considered prior 
to acquisition.

Succession planning for senior posts in the Company 
is reviewed periodically by the Board.

The Board reviews post-acquisition performance.

Appropriate career paths and internal recognition 
programmes are developed for both technical and 
non-technical staff.

Regular reviews are performed to ensure that all elements 
of compensation across the Group are competitive with 
the market.

STRATEGIC REPORTChairman’s introduction to governance

and throughout the technology sector is a key challenge for all 
of us, and there remains significant work to do. The Group is 
seeking to make a material change through its partnerships 
with organisations like the Society of Women Engineers and 
the Board is monitoring developments.

Evaluating the Board’s effectiveness
Each year, the Board undertakes a formal evaluation of its 
effectiveness and this year we carried out an internally 
facilitated evaluation to assist in the development of the 
Board. The results of the Board evaluation confirmed that 
the Board continues to function effectively and that there 
are no significant concerns among the Directors about its 
effectiveness. The Board members were seen as engaged 
and committed while the Board’s culture remains open, 
respectful and constructive. A number of actions were 
identified to further enhance the Board’s effectiveness, 
and further details can be found on page 70. 

People and culture 
The successful performance of the business is only possible 
due to the commitment, abilities and drive of our people. In 
the year, both the Board and management have continued 
to drive our employee engagement programme, build on our 
learning and development offering, and further embed an 
inclusive and safe work culture. Further details may be found 
in the Stakeholder engagement section on pages 26 to 29. 

Re-election of Directors 
In accordance with the 2018 Code provisions and following 
a performance evaluation of those Directors standing for 
re-election at the 2023 Annual General Meeting, I can confirm 
that they all continue to be effective and committed to their 
roles and have sufficient time available to perform their duties. 
Accordingly, as recommended by the Nomination Committee, 
all Directors will be offering themselves for re- election at the 
Company’s Annual General Meeting to be held on Thursday 
4 May 2023. Further information on the Directors can be 
found on pages 64 and 65. 

Annual General Meeting

Dear shareholder
On behalf of the Board, I am pleased to present the 
Governance Report for the year ended 31 December 2022. 
This review and the reports of the Nomination, Audit and 
Remuneration Committees that follow summarise the Board’s 
activities during the year. The Board is committed to high 
standards of corporate governance, and decisions are made 
based on what the Board believes is likely to be for the benefit 
of all stakeholders by promoting and maintaining the 
long-term success of the Company and its reputation. 

Compliance with the 2018 UK Corporate 
Governance Code 
Our approach to governance is based on the concept 
that good corporate governance enhances longer-term 
shareholder value and sets the culture, ethics and values for 
the Group. Consistent with our belief in the importance of 
corporate governance, I am pleased to report that, from 
1 January 2023, the Company is now in full compliance with 
the principles and provisions of the 2018 UK Corporate 
Governance Code (the “2018 Code”). A copy of the 2018 
Code can be found at www.frc.gov.uk. 

Board composition and succession planning
During the year under review, the Nomination Committee 
discussed succession planning for Executive and Non-executive 
Directors and progressive refreshing of the Board. Further 
information about the Nomination Committee’s work can be 
found in the Nomination Committee Report on pages 74 to 76.

Diversity 
The Board supports the FTSE Women Leaders Review, which 
seeks to improve Board and senior leadership gender 
diversity across FTSE companies, and the Parker Review on 
Ethnic Diversity. As at the financial year end, the Board 
comprised five male and three female Directors, meaning 
that just under 40 per cent of our Board is now female, with 
two Board members from ethnic minority backgrounds.

CORPORATE GOVERNANCECompliance with the UK Corporate 
Governance Code
As a premium listed company on the London Stock 
Exchange, the Company is reporting in accordance with 
the UK Corporate Governance Code (the “Code”) published 
in July 2018. The Code sets out standards of good practice 
in relation to Board leadership and Company purpose; 
division of responsibilities; composition, succession and 
evaluation; audit, risk and internal control; and remuneration. 
The Code is published by the UK Financial Reporting 
Council (FRC) and a copy of the Code is available from 
the FRC website at www.frc.org.uk.

The Board confirms that the Company is fully compliant 
with the Code, except for the alignment of the CFO’s 
pension contribution to the level available to the UK 
workforce which occurred on 1 January 2023.

Board leadership and Company purpose
The Board’s ultimate objective is the long-term 
sustainable success of the Company. Read more about 
our strategy in our Strategic Report and how the Board 
achieves this through, amongst other things, stakeholder 
and workforce engagement (pages 26 to 29), establishing 
a clear and aligned Company purpose, strategy and 
values (page 3) and how the Board assesses and monitors 
culture (pages 14 and 15).

Division of responsibilities
The Board consists of two Executive Directors, five 
Independent Non-executive Directors and the Non-executive 
Chairman, who was considered independent on 
appointment to the Board. Additional external

appointments of Board members during 2022 received 
prior Board approval. Directors’ other time commitments 
are in line with the key institutional investor and investor 
body guidelines.

Composition, succession and evaluation
The Nomination Committee report (pages 74 to 76) 
describes its activities during 2022, including information 
on succession planning and diversity and inclusion 
matters. Details of the Board’s effectiveness review which 
took place during the period are set out on page 70 and 
details of Board composition on page 67.

Audit, risk and internal control
The Audit Committee report (pages 77 to 82) describes 
the work of the Committee and how it discharges its roles 
and responsibilities. The Board, supported by the Audit 
Committee and its Risk Sub-Committee, completed a 
robust assessment of the Company’s emerging and principal 
risks during the period under review and has well 
established procedures to manage risk. The Company’s 
disclosures regarding principal risks are set out on pages 
55 to 60.

Remuneration
The Report on Directors’ remuneration on pages 83 to 110 
describes the work of the Remuneration Committee 
during 2022, and sets out how executive remuneration is 
aligned with the Company’s purpose, values and strategy 
and how workforce remuneration and related policies 
have been considered in its decision making regarding 
executive remuneration.

The Board
The Board of Directors is collectively responsible to the 
Company’s shareholders for the direction and oversight 
of the Company to ensure its long-term success.

The Board met regularly throughout the year to approve 
the Group’s strategic objectives, to lead the Group within 
a framework of effective controls which enable risk to be 
assessed and managed, and to ensure that sufficient 
resources are available to meet the objectives set.

There are a number of matters which are specifically reserved 
for the Board’s approval. These are set out in a clearly defined 
schedule which includes: matters relating to the Group’s 
strategic plan; approving the annual business strategy and 
objectives; the nature and extent of principal risks to be taken 
to achieve the strategic objectives; changes relating to 
structure and capital; approval of trading statements, half 
year results, final results and Annual Report and Accounts; 
declaring interim dividends and recommending final 
dividends; the Group’s policies and systems of internal 
control and risk management; approving capital projects, 
acquisitions and disposals valued at over $2 million; and 
provision of adequate succession planning.

The schedule of matters reserved for the Board was reviewed, 
approved and adopted at the December 2022 Board meeting.

Board composition
At the date of this Report, the Board comprises the Non-
executive Chairman, five Independent Non-executive 
Directors and two Executive Directors.

The Chairman and the Non-executive Directors contribute 
entrepreneurial leadership and external expertise and 
experience in areas of importance to the Company, such 
as strategic investments including specific knowledge, 
understanding and experience of growth areas, corporate 
finance, general finance and corporate governance. They 
also contribute independent challenge and rigour to the 
Board’s deliberations and assist in the development of the 
Company’s strategy, scrutiny of the performance of management 
in meeting agreed goals and targets and satisfying 
themselves of the integrity of the Company’s internal controls 
and risk management systems.

The Chairman holds regular discussions with the Non-executive 
Directors, both individually and as a group, without the 
Executive Directors present to ensure a free and frank 
exchange of views on the effectiveness of the Executive 
Directors and senior management.

Committees of the Board
Certain specific responsibilities are delegated to the 
Committees of the Board, notably the Audit, Nomination 
and Remuneration Committees, which operate within clearly 
defined terms of reference and report regularly to the Board. 
Further details are set out in the reports of each Committee 
that follow this statement.

A Disclosure Committee of the Board is also in place, to ensure 
that adequate procedures, systems and controls are 
maintained and operated to enable the Company to fully 
comply with its obligations regarding the timely and accurate 
identification and disclosure of all information to meet the 
legal and regulatory obligations and requirements arising 
from the Companies Act 2006, the FCA’s Listing Rules, the 
Disclosure Guidance and Transparency Rules and the EU 
Market Abuse Regulation, as it forms part of retained EU law. 
The Board notes, however, that the existence of this Disclosure 
Committee does not absolve the Board from its obligations in 
this area. This Committee comprises the CEO, the CFO and 
the Company Secretary, with the Chairman and the Senior 
Independent Non-executive Director authorised to act as 
alternates in the event that a quorum of two members cannot 
be met. By its nature, the Disclosure Committee meets on 
an ad hoc basis, when circumstances require.

Membership of each Committee of the Board is reviewed 
annually and minutes of Committee meetings are made 
available to all Directors on a timely basis. The written terms 
of reference for the Audit, Disclosure, Nomination and 
Remuneration Committees, all of which were reviewed, 
updated where necessary and approved during the year, are 
available on the Company’s website at corporate.spirent.com.

The Chairmen of the Audit, Nomination and Remuneration 
Committees intend to be available at the Annual General 
Meeting to answer questions on the work of their 
respective Committees.

CORPORATE GOVERNANCEDirectors’ statement on corporate governance continued

Committees of the Board continued
An Executive Director-led Management Committee has been 
established to lead and monitor ESG matters and co-ordinate 
the reporting of issues and updates to the Board. Further 
information on the issues dealt with by this Committee are set 
out in the Sustainability section of this Annual Report on pages 
32 to 39.

There is also a formal Risk Sub-Committee of the Audit 
Committee to monitor risks and uncertainties at corporate 
and business unit levels. Further details of this Sub-Committee 
can be found in the Audit Committee report on page 79.

Chairman and CEO
The roles of the Chairman and the CEO are separately held. 
The division of their responsibilities is clearly established, set 
out in writing, and agreed by the Board to ensure that no one 
person has unfettered powers of decision. The Chairman is 
responsible for the operation and leadership of the Board, 
ensuring its effectiveness and setting its agenda. The CEO is 
responsible for leading and managing the Group’s business 
within a set of authorities delegated by the Board and the 
implementation of Board strategy and policy.

Authority for the operational management of the Group’s 
business has been delegated to the CEO for execution or 
further delegation by him for the effective day-to-day running 
and management of the Group.

Senior Independent Director
The role of Senior Independent Director is to act as a 
sounding board for the Chairman and to serve as an 
intermediary for other Directors as required. He is also 
available to shareholders to convey concerns to the Board 
which they have been unable to convey through the Chairman 
or through the Executive Directors. During the year, led by the 
Senior Independent Director, the Non-executive Directors 
have met without the presence of the Chairman (including 
to appraise the Chairman’s performance).

Non-executive Directors
In addition to their responsibilities for strategy and business 
results, the Non-executive Directors play a key role in 
providing a solid foundation for good corporate governance 
and ensure that no individual or group dominates the Board’s 
decision making. They each occupy, or have occupied, senior 
positions in industry, bringing valuable external perspective to 
the Board’s deliberations through their experience and insight 
from other sectors which enables them to contribute 
significantly to Board decision making. The formal letters of 
appointment of the Non-executive Directors are available for 
inspection at the Company’s registered office.

Company Secretary
The Company Secretary & General Counsel is responsible for 
advising and supporting the Chairman and the Board on 
corporate governance matters as well as ensuring that there 
is a smooth flow of information to enable effective decision 
making. All Directors have access to the advice and services 
of the Company Secretary and can take independent 
professional advice in respect of their duties, at the 
Company’s expense.

Independence
The independence of each Non-executive Director is reviewed 
on appointment and at least annually. The Board determined 
that the current Non-executive Directors are each 
independent in character and judgement, save for the 
Chairman who was deemed independent by the Board at the 
date of his appointment. None have been employed by the 
Company previously in any capacity or have any current 
material business relationship with any Group company.

Non-executive Directors at Spirent receive no remuneration 
from the Company other than their fees (detailed in the Report 
on Directors’ remuneration on page 95). Each Non-executive 
Director has confirmed that they do not represent any 
significant shareholder in the Company. No individual or 
group of individuals dominates the Board’s decision making 
and the Code requirement stating that at least half of the 
Board (excluding the Chairman) should comprise independent 
Non-executive Directors is satisfied.

Appointments to the Board
There is a formal, rigorous and transparent procedure for the 
appointment of new Directors to the Board. Details are 
available in the Nomination Committee report on pages 74 
and 76 which also provides details of the Committee’s role 
and activities.

Commitment
The letters of appointment for the Chairman and 
Non-executive Directors set out the expected time 
commitment required of them and are available for 
inspection at the Company’s registered office and at the 
Annual General Meeting.

The Board is mindful of investors’ concerns on ‘overboarding’ 
and the particular attention given to the time commitment 
and availability of Directors. The external commitments of 
each Director are monitored to enable the Board to be 
assured that all of the Directors devote sufficient time and 
attention as is necessary in order to perform their duties. The 
list of external appointments held by Directors can be found 
on pages 64 and 65.

68

Spirent Communications plc Annual Report 2022

CORPORATE GOVERNANCEBoard development
New Directors participate in an induction programme on the operations and activities of the Group, the role of the Board 
and the matters reserved for its decision, the Group’s corporate governance practices and procedures and their duties, 
responsibilities and obligations as directors of a listed public limited company. This programme is normally then supplemented 
by visits to key locations and meetings with, and presentations by, senior executives.

Ongoing training for Directors is available as required and can be provided by means of external courses, internal computer-
based training, briefings from specific consultants or in-house presentations. In addition, the Board’s knowledge and understanding 
of the legal and regulatory environment are updated through the provision of information by the Group’s advisers and by means 
of regular updates from the Company Secretary.

New Directors are encouraged to take advantage of opportunities to meet with major shareholders and attend presentations 
to analysts where possible.

Further details of the appointment and induction process are set out in the Nomination Committee report on pages 74 to 76.

Board meetings
The Board held nine meetings during the year. Discussion papers for Board and Committee meetings are provided to Directors 
in advance of the meeting. Should a Director be unable to participate in a meeting either in person or remotely, the Chairman 
will solicit their views on key terms of business in advance of the relevant meeting, so that these can be shared with the meeting.

The attendance of the Directors at Board and Committee meetings during the year under review is shown in the table below.

Information flow
The Company Secretary manages the provision of information to the Board at appropriate times in consultation with the 
Chairman and CEO. In addition to formal meetings, the Chairman and CEO maintain regular contact with all Directors. The 
Chairman also holds informal meetings with Non-executive Directors, without any of the executives being present, to discuss 
any issues affecting the Group, if this is thought necessary. Regular management updates are sent to Directors to keep the 
Non-executive Directors informed of events and developments throughout the Group between Board meetings and to ensure 
that they are kept fully advised of the latest issues affecting the Group.

Conflicts of interest procedures
The Company has procedures in place, which were reviewed and updated during the year, to deal with the situation where 
a Director has a conflict of interest.

As part of this process, the Board:

•  considers each potential conflict situation separately on its particular facts;

•  considers the potential conflict situation in conjunction with the rest of the Directors’ duties under the Companies Act 2006;

•  keeps records and Board minutes as to authorisations granted by Directors and the scope of any approvals given; and

•  regularly reviews conflict authorisation.

At the start of each Board meeting, the Directors are reminded of their duties under the Companies Act to declare any interests 
in the matters to be discussed and to withdraw from the meeting prior to any voting being held on any such issue. Any Director 
having such an interest would not be considered to form part of the quorum for discussions on that specific matter.

Board activities during 2022
At each Board meeting the CEO presents an update on performance, strategy and business issues such as M&A pipeline 
developments across the Group and the CFO presents a detailed analysis of the financial performance of the business units. 
Senior executives below Board level attend relevant parts of Board meetings in order to make presentations on their areas of 
responsibility; this gives the Board access to a broader group of executives and helps the Directors make ongoing assessments 
of the Group’s succession plans. The Board has a rolling programme of visits to business unit locations to deepen its appreciation 
of the different opportunities and challenges that each unit faces.

Board performance evaluation
The effectiveness of the Board is reviewed at least annually 
and conducted according to the principles of the Code and 
the supporting FRC Guidance on Board Effectiveness. As the 
2021 review was facilitated by Tom Bonham Carter of The 
Effective Board LLP (neither Tom Bonham Carter nor The 
Effective Board LLP have any other connection to the 
Company or to any individual Director) the 2022 review was 
conducted internally by the Chairman and Company Secretary.

Evaluation process
Following discussions between the Chairman and Company 
Secretary, which included the provision of internal policy 
documents, an initial questionnaire was developed for the 
Board and its Audit, Nomination and Remuneration Committees. 
Directors completed the confidential survey online, with their 
answers forming a report to be discussed by the Board. The 
conclusions and insights gained were discussed, with areas of 
focus for 2023 identified for final discussion by the Board.

Evaluation findings
The review established that there continued to be firm 
consensus among the Board members of what defined 
success for the Company both in terms of scope and over 
the short, medium and longer term. Consistent views of the 
Company’s strengths were reported, with the Board confirming 
that challenges and threats to the Company were clearly 
identifiable. The directors agreed that the Company’s strategy 
is well developed and remains appropriate and that the 
Company’s values as defined to employees are fully aligned 
to the strategy.

Board members agreed that there was no longer any 
significant skills gap in the composition of the Board, although 
specific topics were agreed where additional training would 
help to make the Board members more effective. The Board 
considered it was appropriate for the task of implementing 
the strategy of the Company to achieve the define success 
criteria. However, opportunities for further additions to the 
Board would be kept under review with diversity and 
succession planning in mind.

Spirent Communications plc Annual Report 2022

CORPORATE GOVERNANCEBoard action plan
The Board’s areas of focus for 2023 include:

•  identify market segments to drive our longer term growth 

(both organic and inorganic);

•  review implementation of agreed IT strategy;

•  focus on effectiveness of research and development spend;

•  continue to build a deeper understanding of our 
competitors’ strengths and weaknesses; and

•  seek input from industry experts about trends affecting our 
industry and how they perceive Spirent to be positioned to 
respond to those trends.

Election and re-election of Directors
All Non-executive Directors undertake a fixed term of three 
years subject to annual re-election by shareholders. The fixed 
term can be extended and, consistent with best practice, 
would not go beyond nine years unless exceptional 
circumstances were deemed to exist.

The Board confirms that each of the Directors standing for  
re-election has been subject to a formal performance 
evaluation by the Chairman in relation to their duty to act in 
the long-term interests of the Company, while also having 
regard to other stakeholders. The evaluation of the 
Chairman’s performance was carried out by the Senior 
Independent Non-executive Director.

Biographical details, including information on other roles held, 
can be found on pages 64 and 65; an assessment of skills 
held by Board members can be found in the Nomination 
Committee report on page 74.

Financial and business reporting
The Board recognises its responsibility to present a fair, 
balanced and understandable assessment of Spirent in all of 
its reporting obligations. This responsibility covers the Annual 
Report and extends to the Half Year report and other 
regulatory announcements. The Directors consider this Annual 
Report, taken as a whole, to be fair, balanced and 
understandable, providing the information necessary for 
shareholders to assess the Company’s performance, business 
model and strategy. In arriving at this position, the Board asked 
the Audit Committee to review and confirm a process is in 
place to support this assessment. The Audit Committee 
confirmed that a robust approach is in place to support the fair, 
balanced and understandable assessment, details of which 
can be found in the Audit Committee report on pages 77 to 82.

Business model
A description of the Company’s business model for sustainable 
growth is set out in “Our business model” on pages 22 and 23. 
This section provides an explanation of the basis on which the 
Group generates value and preserves it over the long term 
and its strategy for delivering its objectives.

Going concern
After making enquiries, the Directors have a reasonable 
expectation that the Company and the Group have adequate 
resources to continue in operational existence for the 
foreseeable future. Accordingly, and consistent with the 
guidance contained in the document titled “Guidance on Risk 
Management, Internal Control and Related Financial and 
Business Reporting” published by the FRC, they continue to 
adopt the going concern basis in preparing the annual 
financial statements.

Internal control and risk management
The Board acknowledges its responsibilities for the Group’s 
system of internal control in order to facilitate the identification, 
assessment and management of risk, the protection of 
shareholders’ investments and the Group’s assets. The 
Directors recognise that they are responsible for providing a 
return to shareholders which is consistent with the responsible 
assessment and mitigation of risks.

Effective controls ensure that the Group’s exposure to 
avoidable risk is minimised, that adequate accounting records 
are maintained, that the financial information used within the 
business is reliable and that the consolidated accounts 
preparation and financial reporting processes comply with all 
relevant regulatory reporting requirements. The dynamics of 
the Group and the environment within which it operates are 
continually evolving, together with its exposure to risk.

Internal controls can only provide reasonable and not 
absolute assurance against material misstatement or loss. The 
Directors confirm that there is an ongoing, robust process for 
identifying, evaluating and managing the principal risks faced 
by the Group and the operational effectiveness of the related 
controls; this has been in place for the year under review and 
up to the date of approval of the Annual Report and Accounts. 
They also confirm that they have regularly reviewed the system 
of risk management and internal controls utilising the review 
process set out below.

The Directors confirm that a robust assessment of the 
principal risks facing the Company has been carried out, 
including those risks that would threaten its business model, 
future performance, solvency or liquidity. Ongoing 
consideration is also given to potential emerging risks and 
whether or not any of those identified have the potential to 
become a principal risk to the business in the medium to long 
term. More details are set out in the Principal risks and 
uncertainties section on pages 55 to 60 of this Annual Report.

CORPORATE GOVERNANCEDirectors’ statement on corporate governance continued

Management and control of US subsidiary 
Spirent Federal Systems Inc (“Spirent Federal”), which contributed 
approximately $46.1 million to the Group’s revenue in 2022 
(2021 $44.8 million), operates under a Proxy agreement, as 
detailed below, with the remainder of the US business 
operating outside the Proxy regime and therefore allowing 
the same reporting lines and processes as the Group’s other, 
non-regulated businesses.

Spirent Federal and the Proxy arrangement
Spirent Federal Systems Inc is a wholly owned subsidiary of 
Spirent in the United States. It has been placed under a Proxy 
arrangement as it is required by the US National Industrial 
Security Program to maintain facility security clearances and 
to be mitigated of the risks of foreign ownership, control or 
influence for the business it undertakes. Under the Proxy 
agreement, Spirent Federal and the US Department of 
Defense (DoD) are parties to a Proxy agreement that relates 
to the management and operation of Spirent Federal.

In addition to their powers as Directors, the United States 
Government expects the Proxy Holders to exercise 
independently the prerogatives of share ownership of Spirent 
Federal. The Proxy holders have a fiduciary duty, and agree, 
to perform their interests in the best interests of Spirent as a 
shareholder (including the legitimate economic interest), and 
in a manner consistent with the national security interests of 
the United States. Spirent may not remove the Proxy holders 
other than for acts of gross negligence or wilful misconduct or 
for breach of the Proxy agreement (and always only with the 
consent of the US Defense Security Service).

In terms of the power to govern, the Proxy agreement vests 
certain powers solely with the Proxy holders and certain powers 
solely with Spirent. For example, the Proxy holders cannot carry 
out any of the below without Spirent’s express approval: 

•  sell or dispose of, in any manner, capital assets or the 

business of Spirent Federal;

•  pledge, mortgage or encumber assets of Spirent Federal 

for purposes other than obtaining working capital or funds 
for capital improvements;

•  merge, consolidate, reorganise or dissolve Spirent Federal; and

•  file or make any petition under the federal bankruptcy laws 
or similar law or statute of any state or any foreign country.

Spirent can require the above to be carried out and these are, 
therefore, considered to be significant participative features.

Spirent maintains its involvement in Spirent Federal’s activities 
through normal business interaction and liaison with the Chair 
of the Proxy Board. Members of Spirent’s senior management 
team attend meetings of the Proxy Board periodically.

Standards
Guidelines on the minimum Group-wide requirements for 
health and safety and environmental standards are set out in 
policy documents and procedures. There are also guidelines 
on the minimum level of internal control that each of the 
business units should exercise over specified processes. 
Each business has developed and documented policies and 
procedures to comply with the minimum control standards 
established, including procedures for monitoring compliance 
and taking corrective action.

High-level controls
All businesses prepare annual operating plans and budgets 
which are supplemented by regular forecasts throughout the 
year. Performance against budget is monitored both at 
operational level and centrally, with variances being reported 
promptly. The cash position at Group and operational level is 
monitored constantly and variances from expected levels are 
investigated thoroughly. Clearly defined guidelines have been 
established for capital expenditure and investment decisions. 
These include the preparation of budgets, appraisal and 
review procedures, and delegated authority levels.

Financial reporting
Detailed management accounts are prepared every month, 
being consolidated in a single system and reviewed by senior 
management and the Board. They include a comprehensive 
set of financial reports and key performance indicators 
covering commercial and operational issues. Performance 
against budgets and forecasts is discussed regularly at Board 
meetings and at meetings between operational and Group 
management. The adequacy and suitability of key performance 
indicators is reviewed regularly.

Internal audit
All of the internal audit activities are co-ordinated by the 
Head of Internal Audit & Risk who has direct access to the 
Board Chairman and to the Audit Committee Chairman 
and is accountable to the Audit Committee.

All Group businesses are required to comply with the Group’s 
financial control framework that sets out minimum control 
standards. A key function of the Group’s internal audit resource 
is to undertake audits to ensure compliance with the financial 
control framework and make recommendations for 
improvement in controls where appropriate.

Senior members of the Group finance team meet with the 
Chairman of the Audit Committee as appropriate but at least 
annually, without the presence of executive management, and 
have direct access to the Chairman.

Spirent Communications plc Annual Report 2022

CORPORATE GOVERNANCERemuneration
The Report on Directors’ remuneration is set out on pages 83 
to 110 and provides details of our Remuneration Policy and 
how it has been implemented, together with the activities 
of the Remuneration Committee.

Board relations with workforce
Employee feedback in 2022 was gathered in a number of 
ways including regular employee engagement surveys 
throughout the year and regular virtual town-hall meetings 
for all employees and also for smaller sub-groups.

Board relations with shareholders
The Board is committed to maintaining good communications 
with shareholders. As detailed on page 27 of this Annual 
Report, the Chairman, CEO and CFO have regular one-to-
one contact with individual institutional shareholders in order 
to develop an understanding of their views. These are then 
discussed with the Board. Key themes for discussion in 2022 
have continued to include developments in the Company’s 
growth strategy.

All Directors are offered the opportunity to develop a dialogue 
with major shareholders to listen to their views. Presentations 
are made to analysts, investors and prospective investors 
covering the full year and half year results. Executive Directors 
receive regular reports prepared by an independent capital 
markets advisory firm which provides comprehensive 
information relating to the Company’s major shareholders.

The Company seeks to maintain a dialogue with the various 
bodies which monitor the Company’s governance policies 
and procedures.

The Company is always keen to hear the views of its private 
shareholders and we encourage them to access our website 
at corporate.spirent.com for our Company reports and 
business information. Detailed enquiries can be sent to our 
shareholder mailbox at investor.relations@spirent.com.

Any concerns raised by shareholders or their representatives, 
whether expressed directly or through voting patterns at the 
Company’s AGM, are discussed by the Directors. An 
appropriate response is given either specifically to the 
concerned party or, if it is felt to be of wider benefit, made 
available to all shareholders via the Company’s website at 
corporate.spirent.com.

The Board continues to engage with the workforce through its 
local Non-executive Directors designated as the liaison point 
for employees in the three geographical areas in which the 
Company operates:

•  Americas – Edgar Masri;

•  APAC – Wendy Koh; and

•  EMEA – Gary Bullard.

Meetings for each of the three areas took place both in 
person and on a virtual basis, with feedback being reported 
to the Board at its regular meetings. Further details about this 
engagement are set out on pages 26 to 29 of this Annual Report.

Annual General Meeting
The Company’s 2023 Annual General Meeting (2023 AGM) 
will be held at 12.30pm on Thursday 4 May 2023 at the offices 
of UBS at 5 Broadgate, London EC2M 2QS.

The Board continues to view the AGM as a valuable 
opportunity to communicate with private shareholders in 
particular, for whom it provides the opportunity to ask 
questions of the Chairman and, through him, the Chairmen 
of the key Committees and other Directors. The 2023 AGM is 
planned to take place as an in-person meeting, but notifications 
of any alternative arrangements that arise after the publication 
of this Annual Report will be published on the Company’s 
website at corporate.spirent.com/shareholder-information/
agm and by announcement via a Regulatory Information 
Service.

To ensure transparent representation of shareholder views, 
resolutions at the 2023 AGM will be subject to poll voting. This 
gives shareholders the ability to vote directly on the resolutions 
either in person at the meeting, or by submitting their proxy 
instructions to the Company’s Registrar, Equiniti, in advance 
of the meeting.

Key duties
The terms of reference of the Nomination Committee, which 
were reviewed and approved during the year, are available

In accordance with its terms of reference, the Nomination 
Committee’s key duties include: 

•  regularly reviewing the Board structure, size and 

composition (including the skills, knowledge, independence, 
experience and diversity) and making recommendations to 
the Board about suitable candidates for the role of Senior 
Independent Director, and membership of the Audit and 
Remuneration Committees, in consultation with the 
Chairmen of the relevant Committees;

marketplace; and

•  leading the search process and making recommendations 

to the Board for the appointment of new Directors.

Board composition and succession
Following completion as part of the 2022 Board and 
Committee effectiveness review, the Committee agreed that 
there was no significant skills gap in the composition of the 
Board and it was appropriate for the task of implementing the 
strategy of the Company to achieve the defined success 
criteria. However, given the tenure of several Board members, 
preparations would be made for a timely recruitment process 
to identify successors while opportunities for further additions 
to the Board would be kept under review with diversity and 
succession planning in mind.

Skills and training
After completing and reviewing a self-assessed skills audit of 
the Board (the results of which can be seen below), the Board 
identified areas where they would benefit from additional 
training as a group, alongside more specific training for 
individuals on areas where they felt their knowledge and 
understanding could be refreshed.

Spirent Communications plc Annual Report 2022

CORPORATE GOVERNANCETime commitment
The Committee is mindful of investors’ concerns on 
‘overboarding’ and the particular attention given to the time 
commitment and availability of Directors. The external 
commitments of each Director are monitored to enable the 
Board to be assured that all of the Directors devote sufficient 
time and attention as is necessary in order to perform their 
duties. The list of external appointments held by Directors can 
be found on pages 64 and 65.

Performance review
The performance of the Committee was reviewed as part of 
the annual Board effectiveness evaluation and the Committee 
was found to be operating effectively.

Re-election of Directors
All Non-executive Directors undertake a fixed term of three 
years subject to annual re-election by shareholders. The fixed 
term can be extended and, consistent with best practice, 
would not go beyond nine years unless exceptional 
circumstances were deemed to exist.

The Committee reviews the results of the annual Board 
effectiveness evaluation that specifically relate to the 
composition of the Board, and whether the time commitment 
of those who fulfil the roles of Chairman, Senior Independent 
Director and Non-executive Director was appropriate.

The Board confirms that each of the Directors standing 
for re-election has been subject to a formal performance 
evaluation by the Chairman in relation to their duty to act 
in the long-term interests of the Company, while also 
having regard to other stakeholders. The evaluation of 
the Chairman’s performance was carried out by the 
Senior Independent Non-executive Director.

Biographical details for each of the Board Directors, setting 
out skills, experience and information on other roles held, 
are set out on pages 64 and 65.

Succession planning for senior leadership
A key part of the Committee’s role is to maintain an ongoing 
assessment of the senior leadership depth and improving the 
effectiveness of the internal talent pipeline continues to be one 
of the Board’s priorities.

An update to the leadership development and the internal 
succession pipeline was undertaken during 2022, with the 
aim of enhancing visibility and awareness of the Group’s 
leadership talent, strengths and gaps, while also providing 
an open, honest leadership team dialogue on what teams 
contribute and how. The Committee continues to support 
management in recognising that understanding and 
deploying the Group’s talent is a critical and dynamic business 
planning process that can help the organisation to make huge 
strides in cross-functional collaboration and the sharing of 
knowledge and experience.

Spirent’s commitment to diversity 
in talent acquisition
The talent pools we recruit from determine our 
diversity and we have made a concerted effort to 
reach a wider audience when we recruit. We have 
developed a network of university partners and 
recruitment channels to help us to both recruit from 
groups that are currently under-represented, 
especially female engineers and people of colour, and 
support students to reach their full potential. In 2022, 
we added Prairie View A&M University to our university 
network and created a talent acquisition video to drive 
diversity and early career recruitment with our 
partners. We also launched an employee resource 
group to lead talent acquisition and mentoring 
initiatives with Morgan State University, Prairie View 
A&M University and the Society of Women Engineers.

Spirent’s commitment to a diverse 
and inclusive work environment
At Spirent, we know that having a diverse and inclusive 
workforce is essential if we are going to deliver on our 
mission to be global leader and trusted partner for 
innovative technology test and assurance solutions. 
We know how critical diverse and inclusive teams are 
to fuel our innovation and genuinely connect with the 
communities in which we live and work. We embrace 
a culture where difference is valued and openness, 
mutual respect, collaboration and fairness are 
fundamental. Spirent does not tolerate discrimination 
or offensive behaviour of any kind. We are committed 
to creating workplaces that genuinely reflect the 
diversity of the world we serve and provide an environment 
where everyone feels empowered to bring their full, 
authentic self to work.

We strive to enable:

•  workforce representation that reflects the talent market;

•  equitable reward and advancement; and

•  a culture of trust, fairness and respect.

We all need to do more and are committed to 
doing so.

CORPORATE GOVERNANCENomination Committee report continued

Diversity and inclusion
The Committee, the Board of Directors and the Spirent Group 
as a whole continue to pay full regard to the benefits of 
diversity, including gender and ethnic diversity, when searching 
for candidates for the Board, the senior management team 
and other appointments. We believe that better business 
decisions can be made by having representation from 
different genders and cultural backgrounds with differing skill 
sets, experience and knowledge, which reflect our customer 
base and the wider population in our markets.

Diversity of Board members is important to provide the 
necessary range of background experience, values and diversity 
of thinking and perspectives to optimise the decision making 

process. Gender and ethnicity are important aspects of diversity 
which the Chairman and the Committee consider when 
deciding upon the most appropriate composition of the Board.

Spirent as a whole recognises the benefits of diversity beyond 
that of gender, taking account of diversity of social and ethnic 
backgrounds and cognitive and personal strengths when 
considering appointments at all levels, whilst ensuring 
appointments are made on merit and ability to enhance the 
performance of the business.

At 31 December 2022, the Committee reports the Group’s 
performance against the diversity targets set out in the FCA 
Listing Rule 9.8.6(9) and Listing Rule 14.3.33 as follows:

of the Board comprising at least 40 per cent women. Two of the four most recent appointments to the Board have been women, 
and the Committee is committed to requiring a diverse candidate list for all future Board appointments in order to continue to 
drive the representation of women on boards.

CORPORATE GOVERNANCEAudit Committee report

Jonathan Silver
Committee Chairman

Fair, balanced and understandable
In making its recommendation to the Board that the 
Annual Report, taken as a whole, is fair, balanced 
and understandable, the Committee applied robust 
governance arrangements, including:

•  clear guidance and instruction of the disclosure 

requirement provided to contributors;

•  comprehensive Group and subsidiary accounts 
processes, with written confirmations provided 
by each business unit;

•  management teams on the health of the financial 

control environment;

•  a verification process applied to factual content with 
the aim of providing the information necessary to 
assess the Company’s performance, business model 
and strategy;

•  reviews of the Annual Report undertaken at different 
levels of the Group and by the senior management 
team that aim to ensure consistency and overall balance;

•  additional scrutiny by senior management including 

focused review of risk registers;

•  additional Committee reviews of the draft Annual 

Report in advance of final sign-off; and

•  external audit review.

Final approval of the Annual Report is provided by 
the Board, on the recommendation of the Committee.

Dear shareholder
On behalf of the Audit Committee, I am pleased to present 
its report for the period ended 31 December 2022.

The Committee has worked to maintain the integrity of the 
Group’s financial statements and reporting responsibilities 
which are at the heart of good governance. The Committee 
takes great care in carrying out these important tasks, while 
also maintaining a strong internal control and compliance 
culture across the Group.

In the areas of both internal and external audit work, the 
Committee welcomes the return to on-site and in-person 
audits and reviews following the wide lifting of COVID-19 
related restrictions; these provide for a much better interaction 
between management and auditor.

Against a backdrop of continued supply chain pressures, rises 
in inflation and macroeconomic uncertainty, the Committee 
undertook a thorough review of the Group’s principal and 
emerging risks this year and was satisfied that these were 
addressed appropriately in the end-of-year cash modelling 
exercises undertaken to support the Board’s statements on 
going concern and viability.

Finally, an important part of the Committee’s work this year 
has been reviewing preparations for the new reporting and 
governance requirements for companies proposed in the BEIS 
White Paper. The Committee received presentations from 
management and Deloitte on the likely implications for the 
Group and while the implementation dates and content 
remain uncertain, the direction of travel is clear; we need to 
continue to work towards a more formal and stronger control 
and assurance environment. This work is expected to occupy 
a large part of the Committee’s time over the next two years.

I look forward to meeting with shareholders at the Annual 
General Meeting to answer any questions on the work of 
the Committee.

CORPORATE GOVERNANCEAudit Committee report continued

Members
During the year and at the date of this report, Committee 
members were: 

•  overseeing the Group’s policies, procedures and controls for 
preventing bribery and identifying money laundering, and 
the Group’s arrangements for whistleblowing; and

•  Jonathan Silver (Committee Chairman);

•  Maggie Buggie;

•  Gary Bullard;

•  Wendy Koh; and

•  Edgar Masri. 

It is intended that the Audit Committee is comprised of at least 
three members, all of whom are Independent Non-executive 
Directors of the Company with the necessary range of financial 
and commercial expertise to challenge management. Two 
members constitute a quorum.

The Code requires the inclusion of one financially qualified 
member (as recognised by the Consultative Committee of 
Accountancy Bodies) with recent and relevant financial 
experience. Currently, the Committee Chairman fulfils 
this requirement.

•  overseeing the relationship with the Group’s external auditor, 
reporting to the Board each year whether it considers the 
audit contract should be put out to tender taking into 
account any legal requirements for tendering or rotation of 
the audit contract, reviewing and monitoring its objectivity 
and independence including seeking information from the 
external auditor on an annual basis about its policies and 
procedures for maintaining independence, agreeing the 
scope of its work and fees paid to it for audit, assessing the 
effectiveness of the audit process, and agreeing the policy 
in relation to the provision of non-audit services.

How the Committee operates 
All Committee members are expected to be financially literate 
and to have an understanding of the following areas:

•  the principles of, and developments in, financial reporting 

including applicable accounting standards and statements 
of recommended practice;

Key duties
In accordance with its terms of reference, the Audit 
Committee’s key duties include:

•  key aspects of the Company’s operations including 
corporate policies and the Group’s internal control 
environment; 

•  monitoring the integrity of the Group’s financial statements 
and any formal announcements relating to the Company’s 
performance by reviewing significant financial reporting 
judgements contained in them before their submission to 
the Board for approval;

•  on matters of financial reporting, reviewing and challenging 
where necessary the consistency of and any changes to 
accounting and treasury policies, for example considering 
whether the Group has followed appropriate accounting 
policies and made appropriate estimates and judgements, 
the clarity and completeness of disclosure, significant 
adjustments resulting from the audit, and the going concern 
assumption and compliance with auditing standards;

•  at the request of the Board, reviewing the content of the 
Annual Report and Accounts and advising the Board on 
whether, taken as a whole, it is fair, balanced and 
understandable and provides the information necessary 
for shareholders to assess the Company’s position and 
performance, business model and strategy;

•  as requested by the Board, assisting in relation to the 

Board’s assessment of the principal and emerging risks 
facing the Company and the prospects of the Company for 
the purposes of disclosures required in the Annual Report 
and Accounts;

•  reviewing the effectiveness of the Group’s internal financial 

controls, including the policies and overall process for 
assessing established systems of internal financial control 
and timeliness and the effectiveness of corrective action 
taken by management;

•  reviewing the most appropriate fulfilment of the internal 
audit function and agreeing and assessing the annual 
internal audit plan and its effectiveness in the context of 
the Company’s overall risk management system;

78

Spirent Communications plc Annual Report 2022

•  matters which may influence the presentation of accounts 

and key figures;

•  the principles of, and developments in, company law, 

sector-specific laws and other relevant corporate legislation;

•  the role of internal and external auditing and risk 

management; and

•  the regulatory framework for the Group’s businesses.

The Committee invites the Chairman, the CEO, the CFO, the 
Head of Internal Audit & Risk and senior representatives of 
the external auditor to attend its meetings in full, although 
it reserves the right to request any of these individuals 
to withdraw.

During the year, the Committee held two meetings with 
Deloitte LLP, and two meetings with the Head of Internal 
Audit & Risk, without the Executive Directors present.

The Committee has unrestricted access to Company 
documents and information, as well as to employees of the 
Company and the external Auditor.

The Committee’s effectiveness is reviewed on an annual basis 
as part of the Board’s performance evaluation process and in 
2022 the Committee was found to be operating effectively.

The terms of reference of the Audit Committee were reviewed 
and approved during the year and can be viewed on the 
Company’s website at corporate.spirent.com.

Meetings
The Audit Committee met four times during the year, with 
the Committee agenda linked to events in the Group’s 
financial calendar. 

CORPORATE GOVERNANCEActivities during 2022
The Audit Committee’s activities principally related to financial 
reporting, internal control and risk management, the preparation 
for publishing a viability statement and the external audit. The 
Committee considered all material controls, including financial, 
operational and compliance controls and their effectiveness 
and monitored the internal audit plan as carried out by the 
Head of Internal Audit & Risk, assisted by PwC. The Audit 
Committee considered other specific matters such as the 
Group’s approach to IT controls, site security and cybersecurity 
and monitored the Group’s progress in preparations for 
disclosures in this Annual Report based on the Task Force on 
Climate-related Financial Disclosures. The Committee also 
reviewed the development of new reporting and governance 
requirements proposed in the BEIS White Paper, and monitored 
preparations by management in order that the Group is ready 
and able to report on the requirements when they are finalised.

Risk Sub-Committee
During the period under review, the Audit Committee had 
oversight of a Sub-Committee dealing with the risks and 
uncertainties being dealt with on a Group and business 
unit level.

The Risk Sub-Committee met regularly throughout 2022 
to monitor the Group’s risk appetite and registers, with 
a particular focus on supply chain risks and the ongoing 
COVID-19 pandemic.

Financial reporting and significant issues
During the year, the Audit Committee:

•  reviewed the full year and half year financial statements, 
trading updates, key accounting policies and significant 
financial reporting judgements contained therein (with 
particular reference to the critical accounting assumptions 
and judgements as set out in note 2 of the consolidated 
financial statements) and recommended the financial 
statements to the Board for approval;

•  reviewed whether the Annual Report, taken as a whole, is 

fair, balanced and understandable and formed an opinion 
thereon prior to recommending it to the Board;

•  reviewed and monitored risk management processes and 
the potential for risks to impact on the viability of the Group;

•  reviewed and considered assumptions in relation to the 

going concern basis for preparation of financial statements;

•  reviewed, challenged and monitored the appropriateness 

of alternative performance measures; and

•  reviewed the external auditor’s report on the interim review 
and year end audit and management’s responses to the 
issues raised.

The Committee Chairman reports any significant findings 
or identified weaknesses to the Board. 

Significant financial issues considered and 
addressed in relation to the financial statements
The Audit Committee gives careful consideration to those 
aspects of the financial statements that required significant 
accounting judgements or where there is estimation uncertainty. 
These areas are set out in note 2 to the consolidated financial 
statements. The Committee received detailed reports from 
both the CFO and External Auditor on these areas and on 
many other matters which they believed should be drawn to 
the Committee’s attention and challenged the treatment and 
assumptions where it was felt necessary to ensure that the 
judgements were robust and supportable. The external 
auditor’s report on the financial statements was also reviewed, 
with particular reference to those matters reported as 
carrying risks of material misstatement.

Management override of controls
The Audit Committee is aware of the risk that management 
overrides the controls environment that is in place in order to 
misrepresent performance by the business. The effectiveness of 
internal controls is monitored and challenged by the Committee 
both directly and through the continuing internal audit work 
undertaken by the Head of Internal Audit & Risk and PwC.

The Committee is aware that International Accounting 
Standards require the External Auditor to presume risk of 
fraud in respect of management override of controls and that 
as part of its audit programme Deloitte considers the higher 
areas of risk deriving from inappropriate posting of journals, 
unintentional or intentional management bias in key 
judgements used in material estimates and accounting 
for transactions outside the ordinary course of business.

Revenue recognition 
The Committee is mindful of the risk that continuing pressure 
on management to meet certain targets and to respond to 
specific customer requests may drive additional deal 
complexity which could, in turn, lead to complex or judgemental 
accounting, in particular due to the impact of external factors 
on business sentiment. This may result in inappropriate 
recognition of revenue and associated balances. It is also 
aware of the heightened risk around the high volume of 
orders fulfilled around the period end, which is highlighted as 
an additional fraud risk as an area that could be manipulated 
by management.

As part of its update to the Committee, Deloitte discussed the 
procedures performed in relation to reviewing specific large 
and judgemental transactions and revenue recognised 
around the period end. Deloitte and the Committee also 
discussed the procedures performed in relation to the Group’s 
arrangements for sales through distributors or with the 
assistance of agents.

The Committee receives regular reports on management’s 
oversight of areas where significant judgement is exercised 
and challenges findings to ensure compliance with 
accounting standards.

Significant financial issues considered and 
addressed in relation to the financial statements 
continued
Additional areas of financial statement risk
In addition to these areas, the Committee noted the following:

•  Pensions 

The Committee receives regular updates on the accounting 
for the funded defined benefit pension plans. The Committee 
monitors the approach and assumptions made by 
management and advisers in relation to recognition of the 
current surplus. In addition, the Committee monitored the 
project for the transfer of legacy UK pension plans to an 
insurer, which progressed through the year, completing 
in October.

•  Adjusting items 

The Committee kept the definition and use of adjusting items 
under review throughout the period, in particular because of 
the potential impact upon the Group’s reported profitability. 
The Committee paid close attention to the treatment of costs 
connected to the octoScope acquisition in 2021.

•  Tax accounting 

The Committee received regular updates from the VP of 
Global Tax and Group Financial Controller on the 
appropriateness of recognised tax provisions, recoverability 
of deferred tax assets and the key tax judgements. The 
Committee evaluated updates from management in 
respect of uncertain tax positions, the tax provision and the 
deferred tax position. The Committee was satisfied that 
management’s approach to the accounting for taxation 
was appropriate. The Committee also noted Deloitte’s use 
of tax specialists and considered its view on the tax 
accounting matters.

•  Goodwill impairment 

The Committee receives a report setting out the approach 
and outcomes of the Group’s annual goodwill impairment 
exercise which takes place each year, together with additional 
reviews of the impact on the goodwill position of specific 
events or changes to the assumptions made.

Misstatements
Management reported to the Committee that it was not 
aware of any material or immaterial misstatements made 
intentionally to achieve a particular outcome. The External 
Auditor reported to the Committee misstatements it had 
found in the course of its work. After due consideration the 
Committee concurred with management that no 
adjustments were required.

Internal control and risk management 
During the year the Audit Committee:

•  monitored and reviewed internal control and risk 

management systems;

•  reviewed and approved the internal audit programme for 

2022; and

•  reviewed regular reports on taxation, treasury operations, 

health and safety and cybersecurity.

80

Spirent Communications plc Annual Report 2022

The Board is responsible for the effectiveness of the Group’s 
system of internal control, which has been designed and 
implemented to meet the particular requirements of the Group 
and the risks to which it is exposed. Details can be found 
below on the Group’s internal control environment, how risk is 
managed and the Committee’s review of the effectiveness of 
the risk management and internal control systems.

Internal control environment 
The primary aim of the Group’s internal controls is to operate 
a system which is appropriate to the business and which can 
support the Group in delivering its strategic objectives, 
safeguard the Group’s assets and, over time, enhance 
shareholder value. The system is designed to identify, evaluate 
and manage the significant risks faced by the Group rather 
than to eliminate the risk of failure to achieve business 
objectives and can only provide reasonable and not absolute 
assurance against material misstatement or loss. This is in 
accordance with the Guidance on Risk Management, Internal 
Control and Related Financial and Business Reporting issued 
by the FRC in September 2014.

The CFO is responsible for internal financial control and for 
ensuring that the finance department employs a level of 
management and specialists appropriate for maintaining 
financial records and processes that provide financial 
information that is relevant and reliable, complies with 
applicable laws and regulations, and is distributed both 
internally and externally in a timely manner. A review of the 
consolidation and financial statements is undertaken by senior 
management to ensure that the financial position and results 
of the Group are appropriately reflected. All financial 
information published by the Group is subject to the approval 
of the Audit Committee prior to it being approved by the Board.

The following key elements comprise the internal control 
environment:

•  an appropriate organisational structure with clear lines 

of responsibility;

•  an experienced and qualified finance function which 
regularly assesses the possible financial impact of the 
risks facing the Group;

•  a comprehensive annual business planning process 

and strategy review;systems of control procedures and 
delegated authorities which operate within defined 
guidelines, and approval limits for capital and operating 
expenditure together with other key business transactions 
and decisions;

•  a robust financial control, budgeting and forecast system 
which includes regular monitoring, variance analysis, key 
performance indicator reviews and risk and opportunity 
assessments at Board level;procedures by which the 
consolidated financial statements are prepared, which are 
monitored and maintained through the use of internal 
control frameworks addressing key financial reporting risks 
arising from changes in the business and accounting 
standards;

•  established policies and procedures setting out expected 

standards of integrity and ethical standards which reinforce 
the need for all employees to adhere to all legal and 
regulatory requirements;

CORPORATE GOVERNANCE•  an annual internal controls compliance checklist; and

•  the Head of Internal Audit & Risk, who is supported by 

a co-sourced internal audit resource. During the year ended 
31 December 2017, the Group adopted co-source 
arrangements and appointed PwC, which continues to 
support the Head of Internal Audit & Risk to formulate and 
execute the Group’s internal audit plan. The plan for 2022 
was approved to ensure that there was appropriate 
coverage of the internal control environment, strategic 
priorities and key risks identified by the Board. At each 
Committee meeting the Head of Internal Audit & Risk, 
assisted by PwC, gives an update on the progress of the 
internal audit plan, which is reviewed to ensure that it is in 
line with the Committee’s expectations.

During the year the internal audit plan was amended so that 
additional areas were added to the plan based on the changes 
that gave rise to increased levels of risk. These changes to the 
agreed audit plan were approved by the Committee.

The Head of Internal Audit & Risk has direct access to the Board 
Chairman and to the Committee Chairman and is accountable 
to the Committee, meeting regularly with both the Committee 
and its Chairman, without the presence of management, 
to consider the work of internal audit.

The effectiveness of the execution of the internal audit plan is 
monitored at each Audit Committee meeting and also forms 
part of the Board’s annual evaluation process.

The 2022 evaluation confirmed that the Directors are satisfied 
with the arrangements and approach currently in place.

Risk management
Members of the Executive Risk Committee meet to challenge 
and debate the assessment of risk including emerging risks, 
for the Group as a whole and within each business unit, which 
have submitted local risk registers for analysis and ranking 
together with Company-wide risks to form a robust corporate 
risk register. This corporate risk register is presented to the 
Audit Committee at least twice each year. Actions arising from 
the Audit Committee’s review of the corporate risk register are 
fed back to the business units for their management.

Committee oversight
Day-to-day responsibility for effective internal control and risk 
management and monitoring rests with senior management 
at business unit level. During the year, the CFO and Head of 
Internal Audit & Risk attended all Audit Committee meetings to 
report on internal control and risk management and notified 
the Committee of any control weaknesses, control failings and 
risks, their impact and the actions taken to deal with the issues.

Detailed updates on specific areas, such as cybersecurity or 
business continuity, are provided at the Committee’s request.

Business Ethics Policy 
A policy that sets standards of professionalism and integrity 
for all employees and operations was relaunched in 2020 
and is regularly refreshed. The Business Ethics Policy includes 
sections relating to bribery and corruption to ensure that all 
of Spirent’s systems, controls and training comply with the 
anti-bribery and corruption legislation in the countries in 
which we operate, and that a culture of prevention and 
detection of all forms of bribery and corruption is in place. 
Anti-bribery training is required to be taken by certain 
employees periodically. New employees and all designated 
employees completed the training in 2022.

Acquisitions and divestments 
Disciplined due diligence processes and post-acquisition 
integration programmes are in place. 

Fraud
The Board of Directors is aware that it bears the primary 
responsibility for the detection and prevention of fraud. The 
Directors are aware of the potential for fraud and this features 
as an element of the Board’s risk assessment and corporate 
governance procedures. The Audit Committee reviews these 
procedures to ensure that they are in place and working 
effectively. This oversight is supported by the work of the 
Head of Internal Audit & Risk and PwC as part of their 
internal audit work.

The Group’s Business Ethics Policy, which has been 
communicated to all employees, makes clear that employees 
also have a responsibility for fraud prevention and detection 
and any suspicion of fraud will be reported immediately and 
investigated vigorously.

Raising concerns at work 
The Committee aims to ensure that employees are able to raise 
any concern in confidence about any possible improprieties 
in business practices or other matters. A Group-wide 
Whistleblowing Policy is in place and is regularly highlighted 
to employees and an external third party reporting service is 
available to employees for the reporting of any concerns.

Disclosures under this arrangement are investigated promptly 
by the Company Secretary and the Head of Internal Audit & 
Risk, and are escalated to the Executive Directors and the 
Committee as appropriate, with follow-up action being taken 
as soon as practicable thereafter.

The Committee is satisfied that the means for employees to 
raise concerns at work are appropriate to the size and scale 
of the Group.

Spirent Communications plc Annual Report 2022

81

CORPORATE GOVERNANCEAudit Committee report continued

In addition, the Committee monitors the External Audit partner’s 
involvement in his team’s work to ensure sufficient oversight and 
direction of work was evident, in particular with regard to the 
audit of significant components involving judgements.

The effectiveness of the External Auditor also forms part of 
the Board’s annual evaluation process.

Auditor independence 
The Committee assesses the independence and objectivity 
of the External Auditor annually, taking into consideration 
relevant UK law, regulation, the FRC Revised Ethical Standard 
and other professional requirements. Deloitte has provided 
a letter confirming its belief that it remained independent 
throughout 2022 and has discussed with the Committee the 
threats to its independence and the safeguards applied to 
mitigate those threats.

As part of this review, the Committee examined in particular:

•  a report from the External Auditor describing its arrangements 
to identify, report and manage any conflicts of interest; and

•  the extent of non-audit services provided by the External 

Auditor.

Policy on non-audit services 
The Committee is responsible for pre-approving the 
engagement of the External Auditor for any and all non-audit 
services, with the objective of ensuring that the provision of 
such services by the External Auditor does not impair its 
independence or objectivity. Taking into account relevant 
ethical guidance, the Committee’s policy precludes a number 
of non-audit services, including those relating to the 
accounting records and financial statements, internal audit, 
IT consulting, legal and investment services and other services 
deemed by regulators to be precluded.

The Committee accepts that certain work of a non-audit 
nature may be best undertaken by the External Auditor. The 
policy is reviewed annually and financial limits for the 
provision of non-audit services, including audit-related fees 
and other fees, are set on the same annual basis (2022 $0.3 
million (2021 $0.3 million)). These were less than one-third of 
the Group’s audit fee of $1.4 million (2021 $1.3 million). The 
Committee can confirm that no non-audit services were 
provided by Deloitte during the period under review other 
than the interim review fee of $0.1 million (2021 $0.1 million).

External audit 
The Committee is responsible for overseeing the Company’s 
relations with the External Auditor.

The Committee places great importance on ensuring that 
high standards of quality and effectiveness are maintained 
within the external audit process. It considers a number of 
areas in relation to the External Auditor: its performance 
in discharging the audit and interim review of financial 
statements, its independence and objectivity, and its 
re-appointment, remuneration and feedback on these 
matters is given to the External Audit Partner.

Auditor appointment 
Each year the Committee assesses and reports to the Board 
on the qualification, expertise, resources and effectiveness, 
as well as the independence of the External Audit Partner 
and his team.

The Committee notes and confirms compliance with the 
Competition and Markets Authority Order 2014 (the “CMA” 
Order) in respect of statutory audit services for large companies.

In line with the CMA Order and the EU Audit Regulations the 
Committee completed a tender process during 2020 in order 
to select a new external audit firm to replace EY following the 
audit of the 2020 financial statements. After a rigorous 
selection process resulted in a recommendation by the Board 
to shareholders, Deloitte LLP was appointed by the Company 
at its Annual General Meeting on 28 April 2021 to audit the 
financial statements of the Company for the period ending 
31 December 2021 and subsequent financial periods.

There are no contractual obligations in existence that restrict 
the Company’s choice of auditor. 

Auditor effectiveness 
The Committee assesses the effectiveness of the audit process 
on an ongoing basis, with particular attention to the mindset 
and culture, skills, character and knowledge, quality control 
and judgement of the External Auditor in its handling of key 
judgements, its responsiveness to the Committee and its 
commentary where appropriate on the systems of 
internal control.

The Committee holds regular private meetings with the 
External Auditor to assist with its assessment, including 
discussion of:

•  how the External Auditor has identified and addressed 

potential risks to audit quality;

•  the controls in place within the External Audit firm to identify 
risks to audit quality, including the results of internal and 
external inspections of the External Audit team and firm;

•  whether the External Auditor has met the agreed audit plan, 

in particular how it has responded to any changes that 
have been required during the process;

•  feedback from the key people involved in the audit; and

•  the content of the External Auditor’s management letter.

CORPORATE GOVERNANCEReport on Directors’ remuneration

Gary Bullard
Committee Chairman

Compliance statement
This Report on Directors’ remuneration for the year 
ended 31 December 2022 has been prepared on 
behalf of the Board by the Remuneration Committee in 
accordance with Schedule 8 to the Large and Medium 
sized Companies and Groups (Accounts and Reports) 
(Amendment) Regulations 2013 and the relevant 
sections of the Companies Act 2006 and meets the 
requirements of the Listing Rules of the Financial 
Conduct Authority. 

The Report also describes how the Board has complied 
with the provisions of the 2018 UK Corporate Governance 
Code and explains what steps have been taken by the 
Committee to make the Company compliant.

The Report is presented in two parts: the Directors’ 
Annual Remuneration Report and the Directors’ 
Remuneration Policy.

The Directors’ Annual Remuneration Report sets out 
details of how our Remuneration Policy was implemented 
for the year ended 31 December 2022 and how it will be 
applied for the year ending 31 December 2023.

The Company’s Directors’ Remuneration Policy was 
approved by a binding vote at the 2021 AGM and 
became effective on 28 April 2021 and will apply 
for the following three years.

Dear shareholder
I am pleased to present the Directors’ Remuneration Report 
for the year. The Committee’s principal activities in the year 
were to assess the outcomes of performance under the 
Company’s incentive plans and to consult with shareholders 
over a salary increase for the CEO, Eric Updyke, details of 
which are set out below.

Executive pay and shareholder consultation
Spirent operates in a global market with a significant portion 
of its operational footprint in the United States, and this 
shapes the talent market from which we draw the leadership 
of the Group. We must take into account this global context 
when we consider what pay arrangements are competitive, 
motivational and fair.

Eric Updyke was appointed in April 2019 and has implemented 
significant changes to ensure the continued growth of the 
Company. Now approaching four years in the role, the Board 
considers that he is now a proven CEO and are keen to retain 
his services for the next phase of the Company’s growth. As a 
consequence during 2022 we commissioned a detailed 
external benchmark and review of his levels of remuneration. 
This showed that the total remuneration package available to 
our CEO was very significantly adrift of our peers and competitors, 
the large majority of which are based in the US, where he is 
also based. It also showed a significant gap had emerged 
between him and comparable FTSE 250 companies, 
especially on fixed pay.

In accordance with the current Remuneration Policy, the 
Committee took into account the individual’s experience, 
progression since appointment and performance in role. 
Consequently, the Committee consulted with the Company’s 
25 largest shareholders, who account for approximately 
70 per cent of the Company’s issued share capital, with a 
proposal to increase the CEO’s base salary by 15 per cent. 
This change would reposition the CEO’s remuneration at the 
mid-market for similar UK companies. Although he would 
remain well below US peers, the Committee believes that this 
resulting position strikes a balance between recognising his 
performance, experience, and the fact that he is a US national 
running the Group from the US, whilst acknowledging the 
governance environment in which the Company operates.

There was clear support for this change amongst the majority 
of shareholders who responded to the consultation or met 
with myself and the Chairman to discuss in more detail. Many 
shareholders acknowledged that the Committee’s proposal 
was mindful and respectful of the level of pay in the UK 
environment, even though the CEO is US-based. Feedback 
about phasing in any increases over time was considered, 
however on balance, the Committee concluded that since 
there was already such a large gap to the overall total 
remuneration opportunity for US-based executives, and as it 
was almost four years since his appointment, the Committee 
did not feel comfortable waiting longer to implement what it 
concluded was a necessary change. Some shareholders 
indicated that whilst being very supportive of the job that the 
CEO had done thus far, they would struggle to support the 
proposal. The Committee understands that view, but believes 
it is in the best interests of the Company and shareholders to 
retain the CEO.

Spirent Communications plc Annual Report 2022

83

CORPORATE GOVERNANCEReport on Directors’ remuneration continued

For the Annual Incentive, the metrics of profitability, revenue 
and strategic and operational priorities remain the same. 
The Committee believes the targets it has set across all of the 
metrics to be challenging and appropriate, especially in the 
context of the macroeconomic challenges that began to 
impact the Company at the end of 2022. Details of the actual 
targets will be disclosed in the 2023 Annual Report. One-third 
of the Annual Incentive achieved will be deferred into shares, 
to be retained for a period of three years.

We engaged with a number of shareholders during the 
shareholder consultation who expressed that they would 
prefer to see more than one LTIP metric and, in particular, 
would like there to be a metric which was more directly 
aligned to the shareholders’ experience. In response, for the 
LTIP awards in 2023 we retained an EPS growth metric for 
50% of the award, introduced a relative TSR metric for 40% 
of the award and included  an ESG measure for 10% of the 
award. We have, in the past, argued that there is no appropriate 
bespoke TSR peer group and the Committee feels that remains 
the case. Accordingly, the relative TSR metric will be measured 
based on performance compared to the FTSE 250 index as a 
whole (excluding financial services and investment trusts). We 
will be bringing a revised remuneration policy to shareholders 
at the 2024 AGM and will review the LTIP metrics further as 
part of that process.

Other Committee activities in 2022

The Committee’s other activities during the year continue to 
take into account the wider remit introduced by the Code:

•  The Committee reviewed metrics and set targets for Annual 

Incentives and share-based Long-Term Incentives.

•  The Committee considered and approved the reward 

structure and levels of remuneration for each of the CEO’s 
direct reports.

•  The Committee considered and approved the budget of the 

Long-Term Incentive Plan awards for employees and 
approved the awards to the Executive Committee. The 
Committee once again approved the roll-out of the discounted 
employee share purchase plan to all full-time employees.

•  Employee engagement meetings in all three geographies 
continued through the year, with feedback being reported 
to the Board and, where it specifically relates to 
remuneration, to the Remuneration Committee.

I hope you find this report clear and informative. I will be 
available at the 2023 AGM to respond to any questions that 
shareholders may have with respect to the work of 
the Committee.

Gary Bullard
Chairman, Remuneration Committee
7 March 2023

Executive pay and shareholder consultation 
continued
The Committee considers this increase as an exceptional 
one-time repositioning of his fixed pay, and in the future we 
expect that we will keep such increases in line with the wider 
workforce. We also received valuable feedback on other 
areas of our remuneration approach, including LTIP targets, 
which we can implement this year. Next year we will embark 
on another investor consultation prior to bringing a new 
remuneration policy to a binding vote at next year’s AGM.

Executive remuneration outcomes in 2022
In 2022 our management team executed well against the 
targets we set despite macroeconomic challenges which 
impacted the Company later in the year. We grew revenue, 
adjusted operating profit and our order backlog during the 
year. The pay outcomes for our Executive Directors reflect 
that strong performance against the challenging targets we 
set ourselves.

The Annual Incentive for 2022 was based on achievement of 
targets for profitability, revenue and strategic and operational 
priorities. Spirent performed well, continuing to deliver order 
backlog, revenue, and profitability growth in 2022. Full details 
of the specific financial and non-financial targets set and the 
performance against those targets can be found on pages 86 
to 88. One-third of the Annual Incentive achieved for 2022 will 
again be deferred into shares, to be retained for a period of 
three years.

The Long-term Incentive Plan awards granted to the Executive 
Directors in 2019 partially vested in 2022, with 74.9 per cent 
vesting on the Earnings Per Share performance condition and 
100 per cent vesting on the Absolute Total Shareholder Return 
condition, reflecting the strong growth of the Company over 
the performance period.

The third and final tranche of Eric Updyke’s buyout award 
of Restricted Stock (awarded in 2019 under Listing Rule 9.4.2) 
vested in full in May 2022, following the Committee’s consideration 
and approval of his satisfactory performance since his appointment.

I believe that the pay outcomes show that the Remuneration 
Policy acted as intended in 2022. No discretion was exercised 
by the Committee during the year.

Executive remuneration in 2023
As discussed above, the base salary for the CEO has been 
increased by 15 per cent for 2023; base salary for the CFO 
has also been increased by 5 per cent over the prior year.

The Committee reviewed management proposals for wider 
workforce salary increases and was particularly sensitive to 
the proposal for 2023 given the inflationary environment. In 
addition, the Committee reviews pay in the wider workforce 
before setting any pay increases for the Executive Directors. 
The workforce increase was 5 per cent. 

As previously promised, from 1 January 2023 we have now 
aligned our CFO’s pension contribution to the level available 
to the UK workforce, where she is based, bringing the 
Company into compliance with the 2018 UK Corporate 
Governance Code.

Eric Updyke and Paula Bell were each set priorities at the start of 2022, with performance of each target to be equally weighted. 

Services and Solutions (CEO: Eric Updyke; CFO: Paula Bell) 
Objective: Managed Solutions bookings growth.

Managed Solutions growth is a key element of our strategy, providing greater confidence over future revenue projections 
and helping mitigate the impacts of technical cyclicality.

Growth targets for bookings of $35.0 million at entry, $43.5 million at target and $50.0 million at stretch were set by the Committee.

Objective: Demonstrate sustainable, profitable growth with Hyperscaler customers.

Status

Achievement

Achieved

Cloud strategy is an important focus area to drive sustainable, profitable growth. One measure of our progress in this area is 
bookings growth within the Hyperscaler segment. Growth targets for bookings with this group of customers were set at $45.0 million 
at entry, $52.8 million at target and $60.0 million at stretch.

Achievement

0 per cent

Strong conversion of operating profit into free cash flow allows Spirent to fund growth opportunities, both organic and inorganic, 
in addition to making returns to shareholders through dividends. The free cash flow target for the full year assumes budget 
profitability is delivered, and excludes other adjusting items, one-off contributions to the UK pension scheme and other one-off 
adjustments to working capital and tax. Targets were set at $99.0 million at entry, $104.0 million at target and $109.0 million 
at stretch.

achieved under the Annual Incentive into shares, to be retained for a period of three years. This applies to Executive Directors 
employed by the Group at the date of the payment of the 2022 Annual Incentive.

The deferral element of the 2022 Annual Incentive will be applied as follows:

Long-Term Incentive Plan outcomes (audited)
In line with previous years, the operation of the LTIP is such that the EPS and absolute TSR performance measures run over 
different performance periods.

EPS

Absolute TSR

The performance period for EPS performance conditions 
starts at the beginning of the financial year in which the 
award is granted and ends three financial years later.

The performance period for Absolute TSR performance conditions 
starts shortly before the date of grant and ends three years later.

Notes
1.  The level of vesting for the EPS element of the 2020 award is based on the audited EPS figure published in this Annual Report 2022; the estimate value is based 

on the three-month average price of a Spirent Ordinary Share to 31 December 2022 of 267.62 pence.

2.  On appointment to the Company in April 2019 Eric Updyke was granted an award of Restricted Stock to partially compensate him for remuneration at his 

previous employer. When determining this award, the Committee took into account the form and time horizon of the forfeited compensation. This award vests in 
three tranches, subject to continued employment and satisfactory performance in his role as CEO. The third and final tranche, which relates to 33 per cent of the 
total award, vested on 5 May 2022.

3.  Value of vested shares is calculated at the share price on the date of vesting.

Share incentive interests awarded during the year (audited)
In March 2022 the Committee approved an award of Restricted Stock Units to Ms Bell and Mr Updyke under the Deferred Bonus 
Plan representing one-third of the value of the Annual Incentive outcome based on performance during 2021. Using an average 
closing share price for the five days prior to the award date of 221.12 pence, Ms Bell and Mr Updyke received awards of 70,327 
and 131,234 Restricted Stock units respectively; these awards will vest on 10 March 2025, with no further performance conditions 
to be completed.

In March 2022 the Committee approved an award of Performance Shares to Ms Bell and Mr Updyke under the Long-Term 
Incentive Plan equivalent to 175 per cent and 200 per cent of base salary respectively. Using an average closing share price for 
the five days prior to the award date of 240.80 pence, Ms Bell and Mr Updyke received awards of 279,373 and 500,011 Performance 
Shares respectively. This award was subject to a 100 per cent EPS performance condition, with a performance period starting at 
the beginning of the financial year in which the award is made, in this case on 1 January 2022, and ending after three years, in 
this case on 31 December 2024. The adjusted EPS figure reported for the financial period to 31 December 2021, which forms the 
baseline for this performance target, is 16.59 cents.

Spirent Communications plc Annual Report 2022

CORPORATE GOVERNANCECEO pay ratio
For the purposes of this year’s disclosure, the gender pay gap data from our 5 April 2022 snapshot has been used to identify 
the three appropriate employees for comparison with the CEO (Option B). Further detail on the methodology is set out below.

The table below compares the 2022 single figure of remuneration for the individual who fulfilled the role of CEO during the 
period with that of the Group employees who are paid at the 25th percentile (lower quartile), 50th percentile (median) and 
75th percentile (upper quartile) of its UK employee population.

Note 
1.  The data provided for 2019 is the aggregate 2019 single figure of remuneration for the two individuals who fulfilled the role of CEO during the period which 

includes a three-month period where both individuals were receiving remuneration and Annual Incentive payments to both individuals. 

The remuneration figures for all employees were determined at 31 December 2022.

Under Option B, the latest available gender pay gap data is used to identify the best equivalent for three Group employees in 
the UK whose hourly rates of pay are at the 25th, 50th and 75th percentiles for the Group and their total pay and benefits figure 
for 2022 is then calculated. The identified employees are considered to be reasonably representative since the structure of their 
remuneration arrangements is in line with that of the majority of the UK workforce. The table below sets out the salary and total 
pay and benefits for the three identified quartile point employees:

Salary (£)

Total pay and benefits (£)

63,507

75th

(P75)

83,612

102,431

Each employee’s pay and benefits were calculated using each employee’s remuneration, consistent with the CEO remuneration, 
on a full-time equivalent basis. No adjustments were made and no components of pay have been omitted.

Base salaries of all employees, including our Executive Directors, are set with reference to a range of factors including market 
practice, experience and performance in role. In reviewing the ratios the Committee also noted that the CEO’s remuneration 
package is weighted more heavily towards variable remuneration (including the Annual Incentive and Long-Term Incentive Plan) 
than the wider workforce due to the nature of the role. This means the ratio is likely to fluctuate depending on the performance 
of the business and associated outcomes of incentive plans in each year.

The Committee notes that the 2019 ratio data covered a period during which there were two individuals in the role of CEO, one 
of whom (Eric Hutchinson) received a significant vesting of an LTIP award during the period; although the 2020, 2021 and 2022 
data includes the vesting of the tranches of Eric Updyke’s buy-out award of restricted stock, this award was at a lower quantum.

The Committee also notes that the CEO pay ratio has increased over the prior year.  This is as a result of the vesting of the third 
and final tranche of Mr Updyke’s buy-out award of restricted stock falling during the same period as the vesting of his first 
annual LTIP award of performance shares.

The Committee continues to believe the median pay ratio is consistent with the pay, reward and progression policies for our UK 
employees. The salary and total pay and benefits levels for the CEO and median representative employee are competitively 
positioned within the relevant markets and reflect the operation of our remuneration structures. These are effective in appropriately 
incentivising staff, while having regard to the Company’s risk framework and risk appetite and to rewarding the approach as 
well as the outcome of performance.

Shareholding guidelines for Executive Directors (audited)
The Committee believes that to further align their interests with those of shareholders, Executive Directors should have a 
significant shareholding in the Company. Under the 2021 Remuneration Policy, the Committee requires Executive Directors 
to build a holding of shares equivalent in value to 200 per cent of base salary.

Under the 2021 Remuneration Policy, the current Executive Directors will not be required to hold on to beneficially owned 
shares after the end of their employment with the Group. However, any new Executive Directors joining the Company would 
be required to retain the lower of the respective in-role shareholding guideline and the accrual shareholding immediately 
prior to departure for a period of two years.

The chart below sets out the minimum shareholding requirements and the actual shareholdings for the individuals. 
The percentages are a function of base salary, shareholdings and share incentives at 31 December 2022.

Directors affected.

Following consideration, an increase of 4.75 per cent (which is line with the range of salary in the UK and US workforce) was 
agreed. It was also agreed that the additional fees paid to Committee Chairmen and the Senior Independent Non-executive 
Director would not be increased in 2023.

Following consideration, an increase of 4.75 per cent (which is in line with the range of salary increases applied in the UK and US) 
was agreed for the Chairman.

Share incentive interests vesting during 2023 (audited) 
Deferred Bonus Plan: Restricted Stock (March 2023)
Both Ms Bell and Mr Updyke have awards of Restricted Stock under the DBP which are due to vest on 8 March 2023 
(delayed from 5 March 2023 due to the close dealing period for the 2022 full year results). 

These awards are the result of the deferral of one-third of the value of the Annual Incentive achieved based on performance 
in 2019. As such, no further performance conditions are applicable to the awards prior to vesting.

Long-Term Incentive Plan: Performance Shares (May 2023)
Both Ms Bell and Mr Updyke have awards of Performance Shares under the LTIP which are due to vest on 6 May 2023, 
subject to an EPS performance condition and an Absolute TSR performance condition.

The EPS condition has passed the growth threshold required and will vest in full.

The Absolute TSR condition will be tested after the conclusion of the performance period. Current estimates, based on the 
growth in market price of a Spirent Ordinary Share between the beginning of the performance period and the date of this 
report, suggest it is unlikely that this will achieve any vesting.

Full details of the vesting of these awards will be disclosed in the Directors’ Annual remuneration report 2023.

No new shares were issued during the year, with all exercises of share incentives being satisfied by the transfer of shares held 
by the Company’s Employee Share Ownership Trust (ESOT). At the date of this report, the ESOT holds 8.9 million Ordinary Shares 
for the purpose of satisfying the exercises of current and future awards by employees and former employees of the Group.

Spirent Communications plc Annual Report 2022

CORPORATE GOVERNANCEComposition of the Committee 
At the date of this Report, the Remuneration Committee comprises five Independent Non-executive Directors, one of whom acts 
as Committee Chairman. The Company Secretary serves as Secretary to the Committee. All members are considered 
independent within the meaning of the 2018 UK Corporate Governance Code.

Advisers to the Committee 
During the period under review the Committee consulted with the Company’s Chairman, CEO, CFO and Company Secretary & 
General Counsel but not on matters relating to their own remuneration.

Following a formal tender Aon was appointed by the Committee in August 2018 to undertake a market review of executive 
remuneration practices and assist with the design and introduction of an updated Remuneration Policy that was put to 
shareholders at the 2019 Annual General Meeting. In July 2020, following a restructure at Aon, the lead adviser to the Committee 
transferred to work at PwC. The Committee has retained PwC in this role because it values the robust data and advice provided 
and the continuity of provision from the advisers involved. The Committee remains satisfied that PwC is independent, thoughtful 
and challenging. PwC is a member of the Remuneration Consultants Group and complies with its voluntary Code of Conduct in 
respect of the provision of remuneration consulting services, details of which can be found at www.remunerationconsultantsgroup.com.

The fees paid to PwC to carry out work for the Remuneration Committee during the period under review totalled £144,000 (2021 
£60,000). Fees are based on a fixed retainer for certain services and time and materials otherwise. During the year, PwC provided 
other tax and advisory services to the Company. PwC did not have any other connection with the Directors of the Company.

Kepler Associates Limited, which was acquired in June 2015 by Mercer Limited, was appointed by the Committee some years 
ago to provide the results of TSR testing to determine the vesting of share incentives. The Committee has retained Mercer Limited 
in this role because it values the robust data provided and continuity of advice from the consultants involved. The Committee 
remains satisfied that Mercer Limited is independent, thoughtful and challenging. Mercer Limited is a member of the Remuneration 
Consultants Group and complies with its voluntary Code of Conduct in respect of the provision of remuneration consulting 
services, details of which can be found at www.remunerationconsultantsgroup.com, and has no other connection to the 
Company. During the year Mercer did not provide any other services to the Company and did not have any other connection 
with the Directors of the Company.

The fees paid to Mercer Limited to carry out work for the Remuneration Committee during the period under review totalled 
£4,800 (2021 £4,200) and were based on time and materials.

CORPORATE GOVERNANCEReport on Directors’ remuneration continued

Directors’ Remuneration Policy (unaudited)
The Committee’s Policy is to set remuneration levels which ensure that the Executive Directors are fairly and responsibly rewarded 
in return for high levels of performance. The Remuneration Policy aims to promote value creation through transparent alignment 
with the agreed corporate strategy, supporting performance and encouraging the underlying sustainable financial health of the 
business while promoting sound risk management for the benefit of all stakeholders. The Committee believes that the aims of the 
Policy are achieved by ensuring that a significant proportion of executive remuneration is tied to the achievement of the agreed 
corporate strategy and long-term value creation.

The Company’s previous Remuneration Policy was subject to a binding vote at the 2019 AGM on 1 May 2019 and received 95.89 
per cent of all votes cast in favour. The current Policy was subject to a binding vote at the 2021 AGM, receiving 96.40 per cent of all 
votes cast in favour, and is broadly consistent with the previously approved Policy. However, certain changes were made to ensure 
that the new Policy remains fit for purpose for the next three years for the Company and its shareholders. A number of amendments 
to the language of the Policy have been made to improve its clarity. The principal changes from the previously approved Policy are:

•  Post-cessation share ownership requirement: The implementation of a post-cessation share ownership requirement for 

newly appointed Executive Directors, who will be required to hold the lower of the respective in-role shareholding guideline 
and the accrual shareholding immediately prior to departure for a period of two years, in line with the Investment 
Association’s best practice guidance. 

•  Reduction in pension contributions: The alignment of existing Executive Director pension contributions with those of the wider 
workforce from the end of 2022 in line with the UK Corporate Governance Code and Investment Association expectations. 

Considerations of UK Corporate Governance Code principles 
When determining the Remuneration Policy, the Committee was mindful of its obligations under Provision 40 of the Corporate 
Governance Code in order to ensure that the Policy and other remuneration practices were clear, simple, predictable, 
proportional and aligned to the culture of the Company and accounted for reputational and other risks linked to excessive 
reward. Set out below are examples of how the Committee addressed these factors:

Clarity
Remuneration arrangements should be transparent and promote 
effective engagement with shareholders and the workforce.

Simplicity
Remuneration structures should avoid complexity and their 
rationale and operation should be easy to understand.

Risk
Remuneration arrangements should ensure reputational and other 
risks from excessive rewards, and behavioural risks that can arise 
from target-based incentive plans, are identified and mitigated.

Predictability
The range of possible values of rewards to individual Directors 
and any other limits or discretions should be identified and 
explained at the time of approving the Policy.

Proportionality
The link between individual awards, the delivery of strategy and 
the long-term performance of the Company should be clear. 
Outcomes should not reward poor performance.

Alignment to culture 
Incentive schemes should drive behaviours consistent 
with Company purpose, values and strategy.

The Committee consulted with its shareholders on the proposed changes 
within the Policy and received positive feedback.

The Committee believes that the remuneration arrangements are transparent 
and align to market and best practice.

The Committee is not proposing any significant structural changes to the 
incentive plans. Spirent operates two incentive plans, which it believes are 
easy to communicate and for stakeholders to understand and the structure 
of which is aligned to market practice. The performance measures provide 
a clear link to business performance and business strategy.

The Committee is mindful of mitigating risks in relation to excessive reward 
through the application of discretion, as well as through malus and clawback 
provisions in respect of incentive awards.

The range of possible rewards for Executive Directors is considered 
on page 99.

The Committee has the ability to apply discretion in relation to the variable 
pay elements of the awards, for new joiners and for leavers, which were 
revisited as part of the review of the Remuneration Policy.

The Committee strongly believes that the awards implemented ensure 
continued delivery of the short and long-term goals and the 
business strategy.

The Committee also has discretion to adjust incentive outcomes to ensure 
that they reflect the Company’s performance over the relevant period.

The Committee believes that the incentive schemes detailed in the Remuneration 
Policy are consistent with Company purpose, values and strategy.

CORPORATE GOVERNANCEPolicy table
This section of the Report describes the key components of each element of the remuneration arrangements for the Executive Directors.

Component and link to strategy Operation

Maximum opportunity

Framework to assess performance

Fixed remuneration
Base salary

To provide fixed remuneration for 
each role which reflects the size 
and scope of the Executive 
Directors’ responsibilities and their 
individual skills and experience.

Benefits
To provide market levels of benefits 
on a cost-effective basis.

Not applicable.

Base salaries are normally 
reviewed annually.

Set at levels to recruit and retain 
the high-calibre talent needed to 
deliver the Group’s strategy 
without paying more than is 
considered necessary.

Salaries are typically set after 
considering various factors 
including the salary levels in 
companies of a similar size and 
complexity, the responsibilities of 
each individual role, internal 
relativities, progression within the 
role, individual performance and 
an individual’s experience and 
with regard to market salary levels 
in the country in which the 
executive resides. Our overall 
policy, having had due regard to 
the factors noted, is normally to 
target salaries at the median 
market level.

While there is no defined 
maximum salary, any increase 
in salary will ordinarily be (in 
percentage terms) in line with 
those of the wider workforce, 
having regard to the increases 
in the country in which the 
individual resides.

Increases beyond those granted 
to the wider workforce (in 
percentage terms) may be 
awarded in certain 
circumstances, for example 
where there is a change in 
responsibility, progression in the 
role, experience or a significant 
increase in the scale of the role 
and/or size, value and/or 
complexity of the Group.

Details of current salary levels 
are set out in the Annual 
Remuneration Report.

Not applicable.

The overall value of benefits 
will depend on the individual’s 
circumstances and therefore 
there is no formal maximum.

Participation in all-employee 
share plans will be in line with 
relevant statutory limits.

It is intended that the maximum 
value of benefits offered will 
remain broadly in line with 
market practice in the location 
in which the Executive 
Director operates.

May include private health 
cover for the Executive Director 
and their family, life insurance 
cover, permanent health 
insurance and a car allowance.

Executive Directors may 
participate in any all-employee 
share plans which may be 
operated by the Company on the 
same terms as other employees.

Relocation support and any 
associated costs or benefits may 
also be provided if considered by 
the Committee to be appropriate 
and reasonable to meet the 
requirements of the business.

Other benefits may be offered 
from time to time broadly in line 
with local market practice in the 
country of residence of the 
Executive Director. Reasonable 
business-related expenses may be 
reimbursed (including tax thereon, 
if deemed to be a taxable benefit).

Retirement benefits
To provide cost-effective 
and competitive 
post-retirement benefits.

Defined contribution scheme or 
cash allowance in lieu of Company 
pension contributions or a 
combination of both.

Other post-retirement benefits 
may be offered from time to time 
broadly in line with local market 
practice in the country of residence 
of the Executive Director.

Not applicable.

The maximum Company 
contribution is set at 20 per cent 
of base salary (combined cash 
supplement and/or defined 
contribution plan).

For existing Executive Directors, 
the retirement benefits are set in 
line with the general rates 
applicable to the wider 
workforce in their country of 
residence from the end of 2022.

Retirement benefit levels for 
newly appointed Executive 
Directors will be set in line with 
the general rates applicable to 
new employees in the country 
of residence of the new 
Executive Director.

Pension arrangements for 
current Executive Directors 
are set out in the Annual 
Remuneration Report.

Variable remuneration
Annual Incentive

To reward and incentivise the 
achievement of annual financial 
and strategic goals which are 
selected to align the strategy of the 
business and support enhancement 
of shareholder value.

Two-thirds of any bonus earned is 
payable in cash with the remaining 
one-third deferred into shares.

The deferred bonus shares 
ordinarily vest after three years. 
Dividend equivalents may be paid 
on vested shares in respect of 
dividends arising over the period 
between the grant date and the 
vesting date.

Both the cash and deferred share 
elements of the annual bonus 
are subject to clawback and 
malus provisions.

Maximum opportunity is capped 
at 150 per cent of base salary.

The Annual Incentive starts 
accruing from threshold levels of 
performance, which results in 20 
per cent of the maximum payout.

Current maximum potential 
for each Executive Director 
is set out in the Annual 
Remuneration Report.

Annual incentives may be based 
on a mix of financial, individual 
and business objectives with at 
least 50 per cent of the weighting 
being given to financial metrics.

The payment of any bonus is at the 
absolute discretion of the Committee 
and the Committee may exercise its 
discretion to override the 
formulaic outcome.

CORPORATE GOVERNANCEComponent and link to strategy Operation

Maximum opportunity

Framework to assess performance

Long-Term Incentive

To incentivise executives to achieve 
the Company’s long-term strategy 
and enhance sustainable 
shareholder value.

Discretionary awards of conditional 
shares or nil-cost options may be 
granted to Executive Directors 
annually, calculated as a 
percentage of base salary.

Awards will ordinarily vest, subject 
to performance, on the third 
anniversary of grant and will be 
subject to an additional two-year 
holding period post-vesting, during 
which time awarded shares may 
not ordinarily be sold (other than to 
settle tax liabilities incurred by the 
vesting of the award).

Dividend equivalents may be paid 
on vested shares in respect of 
dividends arising over the period 
between the grant date and the 
vesting date (or, where an award is 
structured as a nil-cost option and 
subject to a holding period, to the 
expiry of the holding period or the 
date of exercise (if earlier)).

Malus and clawback provisions will 
apply to all awards made under 
the Spirent Long-Term Incentive Plan.

Maximum plan limit for awards 
is 200 per cent of base salary in 
respect of any financial year.

No more than 25 per cent of the 
relevant part of the award will 
vest for achieving threshold 
performance, increasing to full 
vesting for the achievement of 
maximum performance.

Details of proposed award levels 
are set out in the Annual 
Remuneration Report.

Award levels and performance 
conditions are reviewed before 
each award cycle to ensure they 
remain appropriate.

Awards are currently subject to 
challenging Earnings Per Share and 
Total Shareholder Return targets. 
However, different measures may 
be applied for future award cycles 
as appropriate to reflect the 
business strategy.

A full description of the performance 
conditions applicable to Long-Term 
Incentive awards is set out in the 
Annual Remuneration Report.

In respect of awards granted in 2019 
and beyond, the Committee has the 
discretion to override the formulaic 
out-turn of the award if appropriate 
to do so to take into account the 
underlying financial and operational 
performance of the Company and, 
in exceptional circumstances, 
individual performance.

Notes to the Policy table
Performance conditions applicable to the Annual Incentive
The Annual Incentive is designed to drive and reward excellent short-term financial and operational performance. The 
Committee reviews the Annual Incentive plan measures each year in order to ensure that they are aligned with the Group’s 
strategy. The Committee may alter the choice and weighting of the metrics for future Annual Incentive cycles to reflect the 
changing needs of the business. The Committee also retains the discretion to retrospectively amend the measures, weightings, 
targets and/or method of assessment for the in-year Annual Incentive to take into account changes in the business strategy, 
significant acquisitions or disposals, changes in accounting treatment or other exceptional events to ensure that the scheme is 
able to fulfil its original purpose. The payment of any Annual Incentive is at the sole discretion of the Committee.

Annual Incentives are currently based on:

•  adjusted operating profit – a key driver of shareholder return and a key measure of business success;

•  revenue – reflecting Spirent’s strategic priority of delivering top-line growth; and

•  other strategic and operational priorities – these account for a minority of the Annual Incentive and ensure a rounded 

assessment of performance. 

Performance conditions applicable to awards under the Spirent Long-Term Incentive Plan (LTIP) 
Long-Term Incentive awards will be granted in accordance with the rules of the LTIP and the discretions contained therein. 
The Committee reviews the appropriateness of performance parameters for each award under the LTIP and sets stretching 
performance conditions in light of the Company’s current and expected performance over the performance cycle.

The performance conditions for awards to Executive Directors are (ordinarily) measured over a period of three years and are 
set using a sliding scale of targets and no more than 25 per cent of the award (under each measure) will vest for achieving the 
threshold performance hurdle. The choice of measures may change for future award cycles, but is currently based on:

•  Absolute Total Shareholder Return – generates a strong alignment of interest between executives and shareholders; and

•  Adjusted Earnings per Share – this provides an assessment of the profitability of the revenues delivered and aligns with 

the interests of shareholders. Challenging targets for earnings per share are set based on internal and external forecasts.

The Committee would consult with shareholders in advance of a significant change in the choice or weighting of the 
performance measures to be applied to future award cycles. Under the rules of the LTIP, the Committee has the discretion 
to amend or substitute the performance conditions for in-flight awards in exceptional circumstances, providing the new targets 
are no less challenging than originally envisaged.

Spirent Communications plc Annual Report 2022

105

CORPORATE GOVERNANCEReport on Directors’ remuneration continued

Notes to the Policy table continued
Malus and clawback
The rules of the LTIP and the Company’s Annual Incentive (including any element deferred into shares) include provisions 
for malus and clawback to apply if the Committee concludes that:

•  the relevant individual has committed misconduct;

•  there has been a restatement of any member of the Group’s financial results, due to inaccurate or misleading data;

•  the extent to which an award was granted or has vested was based on inaccuracy or error;

•  the Group (or a business unit within the Group) suffered a material financial loss as a result of circumstances that could 

reasonably have been risk managed;

•  the Company has suffered an instance of corporate failure resulting in the appointment of a liquidator or administrator;

•  a material failure of risk management and/or regulatory non-compliance resulting in damage to the Company’s business 

or reputation; or

•  any other circumstances that the Board considers to have a similar nature or effect.

Clawback may be applied for up to two years following cash payment of an Annual Incentive and vesting under the LTIP, 
and malus up to three years following the granting of awards under the Company’s deferred bonus arrangements.

Shareholding guidelines
The Executive Directors are required to build and maintain a shareholding in the Company equivalent to 200 per cent of salary 
and are expected to retain shares vesting under the deferred annual bonus and LTIP (net of tax) until such time as the guideline 
shareholding has been achieved.

New Executive Directors are required to maintain a post-cessation share ownership requirement to hold the lower of the 
respective in-role shareholding guideline and the actual shareholding immediately prior to departure for a period of two years.

The Company’s policy in respect of vested and unvested share awards post-cessation of employment is set out below in the 
section on Exit Payment Policy.

Discretions retained by the Committee in operating the LTIP and other variable pay schemes 
The Committee operates the Group’s various incentive plans according to their respective rules and (where applicable) in 
accordance with relevant legislation and HMRC guidance. In order to ensure efficient administration of these plans, certain 
operational discretions are reserved to the Committee. These include:

•  determining who may participate in the plans;

•  determining the timing of grants of awards and/or payments under the plans;

•  determining the quantum of any awards and/or payments (within the limits set out in the Policy table above);

•  in exceptional circumstances, determining that a share-based award (or any dividend equivalent) shall be settled (in full or in part) 

in cash;

•  determining the performance measures and targets applicable to an award (in accordance with the statements made in the Policy 

table above);

•  where a participant ceases to be employed by the Company, determining whether “good leaver” status shall apply;

•  determining the extent of vesting of an award based on assessment of the performance conditions, including discretion as to the 
basis on which performance is to be measured if an award vests in advance of normal timetable (on cessation of employment as 
a “good leaver” or on the occurrence of corporate events);

•  whether, and to what extent, pro-ration shall apply in the event of cessation of employment as a “good leaver” or on the occurrence 

of corporate events;

•  whether malus and/or clawback shall be applied to any award and, if so, the extent to which they shall apply; and

•  making appropriate adjustments to awards on account of certain events, such as major changes in the Company’s capital structure.

Spirent Communications plc Annual Report 2022

CORPORATE GOVERNANCEApproach to recruitment remuneration 
In the event that the Company recruits a new Executive Director (either from within the organisation or externally), when 
determining the appropriate remuneration arrangements, the Committee will take into consideration all relevant factors, 
(including but not limited to quantum, the type of remuneration being offered and the jurisdiction which the candidate was 
recruited from) to ensure that arrangements are in the best interests of both shareholders and the Company without paying 
more than is necessary to recruit an executive of the required calibre.

Element

Base salary

Recruitment Policy

The Committee will take into consideration a number of factors, including internal relativities, 
external market forces, skills and current level of pay.

Salary may (but need not necessarily) be set below the normal market rate, with a series 
of planned increases implemented over the following few years to bring it to the desired 
positioning, subject to individual performance.

Benefits

Benefits provision would be in line with normal Policy.

The Committee may agree that the Company will meet appropriate relocation costs.

Retirement benefits

In line with normal Policy.

Annual Incentive

Eligible to take part in the Annual Incentive, with a maximum bonus of up to 150 per cent 
of salary in line with Policy.

Depending on the timing of the appointment, the Committee may deem it appropriate to set 
Annual Incentive performance metrics that are different from those that apply to the current 
Executive Directors for the first performance year in which the appointment falls.

Long-Term Incentive

A normal award of up to 200 per cent of salary, in line with Policy.

Buyout awards

In exceptional circumstances, the Committee may offer additional cash or share incentive 
awards (using Listing Rule 9.4.2, if necessary) to compensate an individual for remuneration 
forfeited on leaving a previous employer.

The awards would not exceed what is felt to be a fair estimate of the remuneration forfeited 
and would reflect (as far as possible) the nature and time horizons attached to that remuneration 
and the impact of any performance conditions. The Company would aim to replace any 
forfeited cash awards with shares wherever possible.

Shareholders will be informed of any such payments at the time of appointment.

For an internal appointment, any remuneration terms awarded in respect of the previous role may either continue on its original 
terms or be adjusted to reflect the new appointment.

When recruiting Non-executive Directors, the remuneration arrangements offered would normally be in line with those paid 
to existing Non-executive Directors, details of which are set out in the Annual Remuneration Report.

Service contracts
Executive Directors
In normal circumstances, it is the Company’s Policy that service contracts for Executive Directors have no fixed term and are 
capable of termination on no more than 12 months’ notice from either the Company or the Executive Director. It is intended 
that this Policy would also apply to new appointments of Executive Directors.

Eric Updyke currently has a service agreement with Spirent Communications, Inc, and, being a US resident, his contract is in line 
with US employment practice and is governed by the laws of the state of New Jersey. Mr Updyke’s service agreement, dated 1 
April 2019, may be terminated on 12 months’ notice from the Company and six months’ notice from Mr Updyke.

The service agreements of Executive Directors are available for inspection at the Company’s registered office on request 
and will be available for inspection at all General Meetings of the Company.

Exit Payment Policy
The Committee is committed to ensuring that it does not pay more than is necessary when Executive Directors leave Spirent 
and its Policy on exit payments is and will continue to be in line with market practice in the country in which the Executive Director 
resides. The current Exit Payment Policy is:

•  service contracts contain provisions for the removal of the Executive Director without compensation for not performing their 

duties to the standard required by the Board or material misconduct;

•  payment in lieu of notice may be paid under service contracts if the relevant notice period is not given to the Executive Director 
or if, having received notice from the Executive Director, the employer does not wish him/her to serve it. Any payment in lieu 
of notice shall ordinarily be paid in monthly instalments, in respect of annual base salary and pension contributions only;

•  unless provided for in the service contract, the Company would seek to apply practical mitigation measures to any payment 
of compensation on termination, for example by reducing payments to reflect payments received in respect of alternative 
employment, taking into account all relevant circumstances;

•  service contracts do not contain provision for additional compensation on termination following a change of control 

(as detailed in the Change of Control provisions set out in the Directors’ Report);

•  service contracts do not contain provision for liquidated damages of any kind; and

•  service contracts contain appropriate provisions to protect the legitimate interests of the Company with respect to preventing 

any terminated Executive Director from working in a business which competes against the Company.

and pension

Annual Incentive

Termination Policy
Payment will be made up to the termination date in line with relevant contractual notice periods 
and will not exceed contractual entitlements.

Unless otherwise provided in the service contract to be consistent with market practice in the country 
in which the Executive Director resides, Executive Directors are not entitled to accrued cash incentives 
payable following termination unless the individual is determined by the Committee to be a good leaver 
(defined as an individual leaving employment due to redundancy, ill health, injury or disability, retirement, 
death, the individual’s employing company ceasing to be under the control of the Group, or a transfer 
of the undertaking in which the individual works (“Good Leaver”)).

Deferred Share 
Bonus Plan

Awards will ordinarily continue to vest on the normal vesting date, unless the Committee determines that 
early vesting should apply. The Committee reserves the discretion to scale the awards down (including 
to nil) in the event of misconduct by the individual or to reflect individual performance.

Spirent Long-Term 
Incentive Plan 2016

Unvested awards will generally lapse at the time of exit. 

For individuals determined by the Committee to be a Good Leaver (see below), the Committee will ordinarily 
assess the performance conditions at the end of the applicable vesting period and unvested awards will 
ordinarily vest on the normal timetable. 

Exceptionally, and always in the case of death, the Committee may assess performance conditions at the point 
of cessation by testing the performance conditions up to (or as close as reasonably practicable to) the date of 
cessation. Awards will then vest following such early assessment of performance.

Except in the case of death, any shares which vest following the assessment of the performance conditions 
would normally be pro-rated to reflect the proportion of the vesting period actually served by the individual.

For the purposes of the LTIP, a Good Leaver is any individual who leaves due to death, ill health, injury, disability, 
agreed retirement, redundancy, a transfer of the business for which the individual works out of the Group or for 
any other reason at the Committee’s discretion (except where the individual is summarily dismissed).

Any post-vesting holding period would normally continue to apply to a leaver’s vested and unvested awards.

Legacy 
arrangements: 
Employee Incentive 
Plan (EIP)

Unvested awards generally lapse at the time of exit. For individuals determined by the Committee to be 
a Good Leaver, performance conditions are assessed by the Committee at the point of exit by testing the 
performance conditions up to the date of exit for TSR performance and to the end of the most recent 
financial period for EPS performance. Vesting is then pro-rated for the proportion of the performance 
period actually served and the individual has 12 months following the date of termination of employment 
in which to exercise them.

108

Spirent Communications plc Annual Report 2022

CORPORATE GOVERNANCEFor all leavers, the Committee may also determine to make a payment in reimbursement of a reasonable level of outplacement 
and legal fees in connection with a settlement agreement. The Company may pay any statutory entitlements, to which an 
Executive Director is entitled, or settle or compromise any claims made in connection with the termination of employment or 
appointment of an Executive Director where the Committee considers such claims to have a reasonable prospect of success 
and that it is in the best interests of the Company to do so. Where appropriate, private health cover may continue for a suitable 
period post-cessation of employment.

The Committee has now introduced a formal Policy in respect of post-cessation shareholdings for new executive directors. 
Following the approval of this Policy and in respect of the incentive awards granted to newly appointed executive directors 
thereafter, the following will ordinarily apply:

•  unvested shares under the Deferred Bonus Plan will continue to vest on the normal vesting date (i.e. up to four years post-cessation);

•  unvested shares under the LTIP will, subject to the participant being a Good Leaver, continue to vest on the normal vesting 

date and be subject to a post-vesting holding period;

•  be subject to a post-vesting holding period;

•  vested shares under the LTIP will remain subject to the holding period; and

•  other beneficially owned shares may be sold as long as the individual continues to maintain a shareholding at least equal 

to the minimum shareholding guidelines which applied during their employment.

Current Executive Directors will also be subject to this Policy, with the exception of its application to other beneficially owned shares, 
over which there will be no sale restrictions.

The above will ensure that the Executive Directors continue to have an interest in the Company after having left employment, promoting 
a culture of sustainable long-term performance. Furthermore, additional safeguards are in place through the malus and clawback 
provisions which can continue to be invoked irrespective of employment status.

In the event of change in control of the Company, in accordance with rules of the respective plans, any outstanding share awards will 
ordinarily vest on the date of such an event. For awards under the LTIP, vesting will be subject to an assessment of achievement against 
the applicable performance conditions and, unless the Board determines otherwise, a reduction to reflect the curtailed vesting period.

Non-executive Directors
All Non-executive Directors have a letter of appointment with the Company for a period of not more than three years, subject to 
the Company’s Articles of Association. However, since 2011 and in accordance with the Code, all Directors who are not stepping 
down from the Board will stand for re-election at each AGM.

The letters of appointment of Non-executive Directors are available for inspection on request and will be available for inspection 
at all General Meetings of the Company. An example of a letter of appointment for a Non-executive Director is available on the 
Company’s website at corporate.spirent.com. Details of the remuneration for Non-executive Directors are set out in the Annual 
report on remuneration.

CORPORATE GOVERNANCEReport on Directors’ remuneration continued

Consideration of employee remuneration arrangements elsewhere in the Group 
When setting the Policy for Directors’ remuneration, the Committee has regard to the pay and employment conditions elsewhere 
within the Group, particularly in the jurisdictions in which the Executive Directors are based. The Committee is kept informed on a 
regular basis of salary increases for the general employee population and takes these into account when determining salary 
increases for Executive Directors and the executive management team.

Where relevant, the Committee seeks to align the Remuneration Policy for Executive Directors with that for other senior managers. 
Selected employees are able to share in the success of the Group through participation in the Management Incentive Plan. 
Executive Directors, other members of the executive management team and key employees are also eligible for participation in 
the Long-Term Incentive Plan.

The Committee is aware of the 2018 UK Corporate Governance Code and its requirements for increasing engagement with 
stakeholders including employees and details of the workforce engagement programme can be found in the Stakeholder 
Engagement section of this Annual Report. 

Consideration of the views of shareholders in setting Remuneration Policy 
The Committee is mindful of the views of shareholders in determining appropriate levels of remuneration and in ensuring that 
shareholder and Director interests are aligned. The Committee is committed to an ongoing dialogue with shareholders and 
seeks shareholder views when any significant changes are proposed to remuneration arrangements. Over the past few years, 
the Committee consulted with major shareholders and shareholder representatives as follows:

•  January 2016: consultation related to the introduction of the new LTIP;

•  December 2017: consultation related to the Committee’s approach to base salary, cash incentives and LTIP awards in 2018;

•  December 2018: consultation regarding the revised Remuneration Policy for which the Committee sought shareholder 

approval at the 2019 Annual General Meeting; and

•  December 2020: consultation regarding the revised Remuneration Policy for which the Committee sought shareholder 

approval at the 2021 Annual General Meeting.

Legacy matters
For the avoidance of doubt, in approving this Remuneration Policy, authority is given to the Company to make payments and 
honour any commitments entered into with current or former Directors (such as the payment of pension or the unwinding of 
legacy share schemes) where the terms were agreed either prior to 24 April 2014 (the effective date of the first Directors’ 
Remuneration Policy) or at a time when a previous Remuneration Policy was in force, or at a time when the relevant individual 
was not a Director of the Company and, in the opinion of the Committee, the payment was not in consideration for the individual 
becoming a Director. Details of any payments will be set out in the Annual Remuneration Report as they arise.

Dilution
The Committee is strongly committed to continuing to manage shareholder dilution in a responsible manner. Details of 
the Company’s dilution are set out in the Annual Remuneration Report.

Research and development 
The Company has chosen, in accordance with the Companies Act 2006 Section 414C(II), to include the disclosure of research 
and development in the Strategic Report on pages 1 to 61. 

Results and dividends 
An interim dividend of 2.63 cents was paid on 16 September 2022. The Directors recommend a final dividend of 4.94 cents per 
Ordinary Share to be paid on 10 May 2023 to shareholders on the Register of Members at close of business on 17 March 2023. 
This would bring the total dividend for the year ended 31 December 2022 to 7.57 cents per Ordinary Share (2021 6.76 cents). This 
payment of the final dividend is subject to shareholder approval at the 2023 Annual General Meeting.

Directors 
Biographies of the Directors currently serving on the Board are set out on pages 64 and 65.

As set out in the Notice of Meeting, all Directors will retire at the 2023 AGM and submit themselves for election or re-election by 
shareholders. All Directors have been subject to a formal and rigorous performance evaluation during the period under review, 
further details of which can be found on pages 70 and 71.

The powers of Directors are described in the Company’s Articles of Association, which can be found on the Company’s website 
at corporate.spirent.com.

Details of Executive Directors’ service contracts and Non-executive Directors’ letters of appointment are set out in the Report 
on Directors’ remuneration on page 95. The interests of the Directors in the shares of the Company are also shown on page 96 
of that report.

The Board has a documented process in place in response to conflicts, details of which are set out on page 69.

Insurance and indemnities
In accordance with its Articles of Association, the Company has granted a qualifying third party indemnity, to the extent 
permitted by law, to each Director. The Company also maintains Directors’ and officers’ liability insurance.

These provisions are qualifying third party indemnity provisions as defined in Section 234 of the Companies Act 2006. Neither 
the Company’s indemnity nor the insurance provides cover in the event that a Director is proven to have acted dishonestly 
or fraudulently.

Change of control provisions
The Company does not have agreements with any Director or employee that would provide compensation for loss of office 
or employment resulting from a takeover except that provisions of the Company’s share incentive plans may cause outstanding 
unvested options and awards granted to employees under such plans to vest on a takeover as follows:

The Company is not aware of any significant agreements to which it is party that take effect, alter or terminate upon a change 
of control of the Company following a takeover.

Share capital
The Company has a single class of share which is divided into Ordinary Shares of 3 & 1/3 pence each. Each Ordinary Share carries 
one vote and all of the Ordinary Shares rank pari passu. There are no special control rights relating to any of the Ordinary Shares. At 
the date of this Report, 611.7 million Ordinary Shares of 3 & 1/3 pence each had been issued which are fully paid up and are listed on 
the London Stock Exchange. The Company also operates a Level 1 American Depositary Receipt (ADR) programme with each ADR 
representing four Ordinary Shares. The ADRs trade on the US over-the-counter market and BNY Mellon is the authorised depositary 
bank for the programme. Further details on share capital are set out in note 29 to the consolidated financial statements and note 17 
to the parent Company financial statements. The rights, including those relating to voting, obligations and any restrictions on transfer 
relating to the Company’s Ordinary Shares, as well as the powers of the Company’s Directors, are set out in the Company’s Articles of 
Association, a copy of which can be found on our website at corporate.spirent.com or can be obtained from Companies House or by 
writing to the Company Secretary.

The Company’s Articles of Association may only be amended by a special resolution at a general meeting of shareholders. The most 
recent changes to the Articles of Association were approved at the 2021 AGM and became effective at the close of that meeting on 
28 April 2021.

The Company has established two employee benefit trusts in connection with the operation of the Company’s share incentive plans: 
the Spirent Employee Share Ownership Trust (ESOT) and the Spirent Sharesave Trust (SST). The trustees of both trusts have waived 
their right to receive dividends on any Ordinary Shares held by them except for a nominal amount of 1 pence other than for those 
Ordinary Shares held in the ESOT which are the beneficial property of an employee/shareholder.

For further details on the employee benefit trusts see “Investment in own Ordinary Shares” in note 29 to the consolidated financial 
statements and note 17 to the parent Company financial statements. The Trustees of both trusts do not vote their Ordinary Shares, 
except for those Ordinary Shares held in the ESOT that are the beneficial property of an employee/shareholder, which the trustees 
will vote in accordance with the instructions received from the beneficial owner.

Spirent Communications plc Annual Report 2022

CORPORATE GOVERNANCERestrictions on share transfers
There are no restrictions on the transfer of Ordinary Shares in the capital of the Company other than certain restrictions which 
may from time to time be imposed by law, for example insider trading law or as required under the Company’s Remuneration 
Policy for Executive Directors. In accordance with the Market Abuse Regulation, certain employees are required to seek the 
approval of the Company prior to dealing in its securities.

The Company is not aware of any agreements between shareholders that may result in restrictions on the transfer of securities 
or on voting rights. The Company is also not aware of any contract of significance between itself or any subsidiary undertaking 
and a controlling shareholder.

Powers for issue of new shares 
During the year to 31 December 2022 and to the date of this Report, no new Ordinary Shares have been allotted as a result 
of the exercise of options and rights pursuant to the Company’s share incentive plans.

At each AGM the Directors seek authority to allot shares for cash and to disapply pre-emption rights within prescribed limits. 
At the 2023 AGM authority will be sought to allot new Ordinary Shares up to a nominal value of £6,797,132, which is equal to 
approximately 33.3 per cent of the Company’s issued share capital as at 7 March 2023.

Return of capital 
The Company was first authorised to repurchase up to 14.99 per cent of its own issued Ordinary Shares, within certain limits and 
as permitted by the Company’s Articles of Association, at the 2006 AGM. This authority has been renewed at each subsequent 
AGM, reducing to 9.99 per cent at the 2010 AGM and subsequent AGMs. The authority from the 2022 AGM remains valid until 
the earlier of the 2023 AGM or 30 June 2023. Since the Company began returning capital to shareholders in May 2006, a total 
of £270.2 million has been returned through the repurchase of 397.6 million Ordinary Shares. No shares were repurchased 
during 2022 or to the date of this Report.

The Company will seek authority to repurchase up to 9.99 per cent of its own Ordinary Shares at the 2023 AGM to facilitate any 
further return of capital, if the Board concludes that it is in the best interests of shareholders to do so.

CORPORATE GOVERNANCEDirectors’ report continued

Political donations 
In accordance with the Group’s Business Ethics Policy, no 
political donations were made during the year (2021 nil).

Going concern 
After making appropriate enquiries and taking into account 
the matters set out in the Principal risks and uncertainties 
section on pages 55 to 60 of this Annual Report, the Directors 
have a reasonable expectation that the Group has adequate 
resources to continue in operational existence for the 
foreseeable future. For this reason, they continue to adopt the 
going concern basis when preparing the financial statements. 

Viability Statement 
In accordance with provision 31 of the 2018 UK Corporate 
Governance Code, the Directors have assessed the viability 
of the Group and concluded whether they have a reasonable 
expectation that the Group will be able to continue in 
operation and meet its liabilities as they fall due over the 
period of assessment.

The Board has concluded that the most appropriate period 
for this assessment should be three years, which is consistent 
with the period used in other forward-looking areas of the 
financial statements.

This period was selected for the following reasons:

•  the Group’s strategic planning cycle covers a three-year 

period;

•  the Board reviews a three-year financial corporate plan;

•  it reflects the period over which the principal risks would 

be realised; and

•  when considering a major investment in product 

development, three years is considered by the Board to 
be a reasonable time horizon in which the product should 
achieve meaningful sales.

The Board’s assessment has been made with reference to the 
Group’s current financial position and prospects, the budget 
for 2023, the Group’s long-term strategy, the Board’s risk 
appetite and the Group’s principal risks and uncertainties as 
set out on pages 55 to 60 of this Annual Report.

The plans and cash flow projections used as the basis for the 
assessment were the three-year strategic plan. They were 
drawn up on the basis that the Group ends 2022 with a cash 
balance of $209.6 million and maintains a cash balance 
sufficient to fund normal operations, and that there will be 
no material changes to the business structure throughout 
the review period.

The Board has reviewed plausible and severe stress tests 
based on the occurrence of a combination of the principal 
risks to which the Group is exposed, considering the potential 
impact of these risks on the business model, future 
performance, solvency and liquidity over the period. The 
analysis also included a reverse stress test scenario to 
illustrate the revenue reduction in the 12 months following 
approval of the financial statements that would lead to the 
Group ceasing to be a going concern. Further detail on the 
scenarios modelled and the principal risks considered is 
disclosed on page 56.

114

Spirent Communications plc Annual Report 2022

In each of the scenarios the Group was able to continue 
operating and generating free cash flow. The reverse stress 
test required such an extreme reduction in revenue that the 
likelihood of occurrence is considered to be remote and 
therefore does not represent a realistic threat to the viability 
of the Group. In reaching this conclusion the Directors 
considered the 2023 budget, the uncertainties arising from 
the macroeconomic backdrop and inflationary pressures, 
the magnitude of the revenue reduction and the ability of 
the Group to take realistic and successful mitigating actions, 
which are not factored into the reverse stress test scenario.

Based on this assessment and the expected successful 
impact of mitigating actions, the Directors have a reasonable 
expectation that the Group will be able to continue in operation 
and meet its liabilities as they fall due over the three-year period.

Disclosure of information to auditor 
Each of the Directors of the Company at the date of this 
Report confirms that: 

•  so far as the Director is aware, there is no information 
needed by the Company’s auditor in connection with 
preparing its report of which the Company’s auditor is 
unaware; and

•  he/she has taken all the steps that he/she ought to have 

taken as a Director in order to make himself/herself aware 
of any information needed by the Company’s auditor in 
connection with preparing its report and to establish that 
the Company’s auditor is aware of that information. 

Independent External Auditor 
As described in more detail on page 82 of the Audit Committee 
report, an audit tender process was completed during 2020, 
and at the 2021 AGM, the Board gained approval from 
shareholders to appoint Deloitte as auditor in April 2021.

Having carried out a review of its effectiveness, the Audit 
Committee has recommended to the Board the re-appointment 
of Deloitte LLP. The re-appointment and a resolution to that 
effect will be on the agenda at the 2023 AGM. Deloitte LLP has 
indicated its willingness to continue as auditor. The Audit 
Committee will also be responsible for determining the audit 
fee on behalf of the Board.

Annual General Meeting 
The Company’s 2023 Annual General Meeting (2023 AGM) 
will be held at 12.30pm on Thursday 4 May 2023 at the offices 
of UBS at 5 Broadgate, London EC2M 2QS.

CORPORATE GOVERNANCEDirectors’ responsibilities statement

The Directors are responsible for preparing the Annual Report, 
the Report on Directors’ remuneration, the consolidated 
financial statements of the Group and the financial statements 
of the parent Company in accordance with applicable United 
Kingdom law and regulations.

and in respect of the parent Company financial statements, 
FRS101, is insufficient to enable users to understand the impact 
of particular transactions, other events and conditions on the 
Group and parent Company financial position and financial 
performance; and

Company law requires the Directors to prepare financial 
statements for each financial year. Under that law they have 
elected to prepare the consolidated financial statements of the 
Group in accordance with the United Kingdom adopted 
International Accounting Standards. The Directors have elected 
to prepare the parent Company financial statements in 
accordance with United Kingdom Generally Accepted 
Accounting Practice (United Kingdom Accounting Standards and 
applicable law) including FRS 101 “Reduced Disclosure 
Framework”. Under company law the Directors must not approve 
the financial statements unless they are satisfied that they give a 
true and fair view of the state of affairs of the Company and of the 
profit or loss of the Company for that period.

The consolidated financial statements of the Group are 
required by law and International Accounting Standards to 
present fairly for each financial period the financial position 
and performance of the Group; the Companies Act 2006 
provides, in relation to such financial statements, that 
references in the relevant part of that Act to financial 
statements giving a true and fair view are references to their 
achieving a fair presentation.

Under the Financial Conduct Authority’s Disclosure Guidance 
and Transparency Rules, consolidated financial statements 
are required to be prepared in accordance with UK adopted 
International Accounting Standards.

•  make an assessment of the Company’s ability to continue

Independent auditor’s report to the members 
of Spirent Communications plc

Report on the audit of the financial statements

1. Opinion

In our opinion:

•  the financial statements of Spirent Communications plc (the “parent Company”) and its subsidiaries (the “Group”) give 
a true and fair view of the state of the Group’s and of the parent Company’s affairs as at 31 December 2022 and of 
the Group’s profit for the year then ended;

•  the Group financial statements have been properly prepared in accordance with United Kingdom adopted international 

accounting standards; 

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

Accepted Accounting Practice, including Financial Reporting Standard 101 “Reduced Disclosure Framework”; and

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

We have audited the financial statements which comprise:

•  the consolidated income statement;

•  the consolidated statement of comprehensive income;

•  the consolidated and parent Company balance sheets;

•  the consolidated and parent Company statements of changes in equity;

•  the consolidated cash flow statement; and

•  the related notes 1 to 34 and 1 to 17.

The financial reporting framework that has been applied in the preparation of the Group financial statements is applicable 
law and United Kingdom adopted international accounting standards. 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 FRS 101 “Reduced Disclosure Framework” (United Kingdom Generally Accepted Accounting Practice).

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

We are independent of the Group and the parent Company in accordance with the ethical requirements that are relevant to our 
audit of the financial statements in the UK, including the Financial Reporting Council’s (the ‘FRC’s’) Ethical Standard as applied 
to listed public interest entities, and we have fulfilled our other ethical responsibilities in accordance with these requirements. 
We confirm that we have not provided any non-audit services prohibited by the FRC’s Ethical Standard to the Group or the 
parent Company. The non-audit services provided to the Group and parent Company for the year are disclosed in note 4 
to the financial statements. 

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

FINANCIAL STATEMENTS3. Summary of our audit approach

Key audit matters

The key audit matter that we identified in the current year was appropriateness of revenue recognition.

Materiality

Scoping

Significant changes 
in our approach

The materiality that we used for the Group financial statements was $5.9 million which was determined 
based on 5 per cent of Group profit before tax.

The following components were full scope: Spirent Communications plc, Spirent Communications Inc, 
Spirent Federal Systems Inc, Spirent Communications (Asia) Limited. In addition, the components not in full 
scope were subject to either analytical procedures (carried out by the Group audit team) or specified audit 
procedures (performed by our either the Group audit team or component auditors). 

The components, which were either full or specified account balances scope in the current year, contribute 
94 per cent of revenue, 86 per cent of profit before tax and 94 per cent of net assets. 

Following our first-year audit in the prior year we have continued to extend our testing of internal controls. 

4. Conclusions relating to going concern
In auditing the financial statements, we have concluded that the Directors’ use of the going concern basis of accounting in 
the preparation of the financial statements is appropriate.

Our evaluation of the Directors’ assessment of the Group’s and parent Company’s ability to continue to adopt the going concern 
basis of accounting included:

•  understanding management’s process in performing the going concern assessment;

•  considering the cash flow forecasts and the scenario analysis prepared by management and evaluating the Group’s ability 

to support itself without accessing external funding, noting that the Group is not exposed to interest rate volatility as there is no 
external debt financing;

•  applying of sensitivities to cash flows including the potential impact of US-China trade relations or slower than expected 

growth in the 5G market;

•  performing inquiries of Management regarding the assumptions used in the going concern models; 

•  assessing the mathematical accuracy of the forecasts produced and the historical accuracy of managements forecasts;

•  reading analyst reports, industry data and other external financial information to determine if it provided corroborative 

or contradictory evidence in relation to Management’s assumptions; and

•  evaluating the Group’s disclosures on going concern against the requirements of IAS 1.

Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, 
individually or collectively, may cast significant doubt on the Group’s and parent Company’s ability to continue as a going 
concern for a period of at least 12 months from when the financial statements are authorised for issue.

In relation to the reporting on how the Group has applied the UK Corporate Governance Code, we have nothing material to add 
or draw attention to in relation to the Directors’ statement in the financial statements about whether the Directors considered it 
appropriate to adopt the going concern basis of accounting.

Our responsibilities and the responsibilities of the Directors with respect to going concern are described in the relevant sections 
of this report.

5. Key audit matters
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. These matters included those which had the greatest effect on: the overall audit strategy, the allocation 
of resources in the audit; and directing the efforts of the engagement team.

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.

5.1. Appropriateness of revenue recognition 

Appropriateness of 
revenue recognition

Refer to page 79 (Audit Committee Report) and Notes 2 (Accounting Policies) and 3 (Operating Segments). 

Revenue: $607.5 million (2021 $576.0 million)

The Group’s principal activity is the sale of hardware, software, support and services for the testing and 
assurance of networks. In general, the performance obligations align with the types of products sold with 
hardware and software recognised immediately, support recognised over the life of the support contract 
and services recognised over the period in which the sale is performed or on a milestone basis. The Group 
also experiences significant seasonality, predominantly due to the timing of the budgetary cycles of the 
Group’s principal customers and markets.

Given the nature of the Group’s products and services there is judgement involved in the allocation of 
revenue between the different performance obligations which impacts the timing of revenue recognition 
and specifically there is a risk associated with cut-off given the significant seasonality, with sales peaking 
at each quarter end, most notably in December. 

The timing of revenue recognition can also be complicated by management’s use of distributors or 
intermediary selling agents in jurisdictions where they have no physical presence or are otherwise required 
to use an intermediary third party. This extends the cut-off risk due to the necessity of assessing whether 
the fulfilment of the Company’s performance obligations are determinant on delivery by the intermediary 
to the end customer.

The transaction price in the contract is allocated across these performance obligations based on the 
standalone selling prices identified by management. This identification of standalone selling prices involves 
judgement, involves multiple inputs and calculations, and has a direct impact on the timing and amount of 
revenue recognised. 

Where sales are only partially delivered, management judgement is required to be exercised in the 
application of IFRS 15 as to whether the delivered elements qualify for recognition prior to all contractual 
deliverables being shipped.

We assessed revenue recognition as a potential risk of fraud as revenue is one of the KPIs for both external 
communications and management incentives.

FINANCIAL STATEMENTS5. Key audit matters continued
5.1. Appropriateness of revenue recognition continued

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

Testing of relevant controls
We obtained an understanding of and tested relevant controls within management’s revenue recognition process. 

We obtained an understanding of and tested relevant controls including those over key IT systems and 
tools used in the revenue recognition process and financial reporting. This included both the applications 
and infrastructure supporting these systems.

Evaluating key judgements in the revenue recognition process
In order to test the timing of revenue recognition, including for partial shipments, we performed testing of 
all material orders placed around the period end and a sample of the other orders to corroborate that 
the activity required for revenue recognition had occurred within the period under audit. This included:

•  obtaining shipping records for physical items and evaluating that the dates of shipment and receipt 

supported the Group’s revenue recognition;

•  reviewing customer acceptance correspondence for completed activities;

•  considering the nature of the items delivered on partially completed orders and assessing whether 

the performance obligations were sufficiently distinct to have independent value without the full order 
having been delivered;

•  assessing contract terms where revenue is milestone based and assessing whether where a milestone 

had been achieved this was supportable based upon agreement with the customer; and

•  direct testing of the price-list used by management to determine the stand-alone selling price of 

their products.

We performed additional procedures where management were selling through a distributor or sales 
channel partner, including direct confirmation, to understand the nature of the agreement between the 
parties and evaluate management’s judgement that the revenue recognition timing was appropriate, 
based upon the transferring of risks and rewards to the customer.

Key observations

Based on the work performed we concluded that the revenue recognition is appropriate.

6. Our application of materiality
6.1. Materiality
We define materiality as the magnitude of misstatement in the financial statements that makes it probable that the economic 
decisions of a reasonably knowledgeable person would be changed or influenced. We use materiality both in planning the 
scope of our audit work and in evaluating the results of our work.

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

Group financial statements

Parent Company financial statements

Materiality

$5.9 million (2021 $5.4 million)

$2.6 million (2021 $2.4 million)

Basis for determining 
materiality

5.0 per cent of pre-tax profit

0.5 per cent of net assets

Rationale for  
the benchmark  
applied

Pre-tax profit is considered the most appropriate 
benchmark as the principal indicator of the 
Group’s overall profitability.

At year end we re-considered the materiality 
based upon actual profit and confirmed that the 
determined level remained appropriate. 

The level of parent Company materiality was capped 
at 45 per cent of the Group performance materiality.

The parent Company includes both the UK trading 
entities of the Group and the head office. In practice 
the value of the standalone parent Company 
financial statement to users is in relation to the 
assets and equity of the business and as such net 
assets has been used as the principal benchmark. 

However, as the parent Company is also a trading 
entity it was also considered that this was an 
appropriate level relative to the revenue generation, 
assets and profitability of the entity.

6.2. Performance materiality
We set performance materiality at a level lower than materiality to reduce the probability that, in aggregate, uncorrected 
and undetected misstatements exceed the materiality for the financial statements as a whole.

70 per cent of Group materiality (2021 70 per cent) 70 per cent of parent Company materiality (2021 70

In determining performance materiality, we considered the following factors: 

a.  the quality of the control environment;

b.  corrected and uncorrected misstatements identified in previous audits; and

c. 

the relative stability of the Group in terms of its trading and operations.

6.3. Error reporting threshold
We agreed with the Audit Committee that we would report to the Committee all audit differences in excess of $295,000 (2021 $267,500), 
as well as differences below that threshold that, in our view, warranted reporting on qualitative grounds. We also report to the Audit 
Committee on disclosure matters that we identified when assessing the overall presentation of the financial statements.

Spirent Communications plc Annual Report 2022

FINANCIAL STATEMENTS7. An overview of the scope of our audit
7.1. Identification and scoping of components
We performed our scoping of the Group audit on the basis of our understanding of the Group and its environment, including 
Group-wide controls, and assessing the audit risks. This exercise has considered the relative size of each reporting unit’s 
contribution to revenue, profit before tax and adjusted profit before tax as well as other components we consider to be 
significant in relation to their potential risk.

The Group has three major accounting hubs located in the UK, USA and Hong Kong where the local finance teams are 
responsible for the recording and reporting of the Group’s financial performance. The UK based finance team are responsible 
for the Europe, Middle East and Africa region and the Hong Kong team are responsible for the Asia Pacific region. The relative 
size of these geographies is set out in note 3 (Operating Segments). 

This resulted in full-scope audits being performed for the principal trading entities in the UK, Asia Pacific and the USA as well 
as for the Group’s Federal business, also based in the US.

Additionally, our audit planning identified 3 components, located in the UK, USA and China where we consider there to be a 
reasonable possibility of material misstatement in specific balances within the financial statements. The relevant component 
teams have performed audit work over these specific balances.

The Group engagement team performed all audit work in respect of the consolidation, share-based payments, goodwill 
impairment, UK defined benefit pension schemes and all audit work over the parent Company entity including the Group’s UK 
trading activities. In addition, the Group engagement team reviewed the performance of all components not identified as in full 
scope or specified account balance scope to ensure that there were no indications of additional risks of material misstatement 
within the residual balances.

As each of the components maintains separate financial records, we have engaged component auditors from the Deloitte 
member firms in the USA and Hong Kong to perform procedures under our direction and supervision.

7.2. Our consideration of the control environment 
We obtained an understanding of and tested general IT controls over IT systems that were key to the Group’s revenue 
recognition process. These included principally the global instances of the Group’s ERP, the system that contains the Group’s 
general ledger, but also extended to certain tools the Company uses as complementary to those systems. We also obtained an 
understanding of and tested relevant controls over the supporting infrastructure of those systems including databases and 
operating systems.

We performed detailed walkthroughs of all relevant processes and obtained an understanding of relevant controls over revenue 
and those that addressed a significant risk of material misstatement. We have performed testing of relevant controls over 
revenue globally and relied on controls while testing the revenue balance. We have also obtained an understanding of controls 
for further relevant account balances, including inventory. 

In particular in the US, the Group’s key trading region, we obtained an understanding of and tested relevant controls over all 
material processes and the component team relied on these relevant controls in the performance of their testing. During the 
course of our audit, we placed reliance on a number of relevant revenue controls.

Management continued to focus on formalising and enhancing the controls in place over revenue, in anticipation of changes to 
the UK corporate governance framework as explained further in the Audit Committee Report on page 79.

7. An overview of the scope of our audit continued
7.3. Our consideration of climate-related risks
In planning our audit, we have considered the potential impact of climate change on the Group’s business and its 
financial statements. Our risk assessment procedures included an understanding of management’s process for identifying and 
considering climate-related risks and assessing whether the risks were consistent with our understanding of the entity. 

The Group continues to focus on its assessment of the potential impacts of environmental, social and governance (ESG) related 
risks, including climate change, as outlined on pages 32 to 39. The risks identified by management include the potential for 
energy costs increases in the short term and in the medium term, the potential for physical site damage, increased insurance 
costs and capital expenditure and the potential for supplier disruption.

As a part of our audit, we have: 

•  obtained an understanding management’s climate-related risk assessment and challenged the key assumptions;

•  held discussions with management to understand their governance process, the process of identifying climate-related risks, 

the determination of mitigating actions and the impact on the Group’s financial statements; and 

•  read the disclosures in the strategic report to whether they are materially consistent with the financial statements and our 

knowledge obtained in the audit.

Management has developed two climate change scenarios and determined that there is no material impact arising from 
climate change on the judgements and estimates made in the financial statements, as disclosed on page 35.

7.4 Working with other auditors
In order to direct and supervise the component auditors we held regular formal video calls with all teams to ensure that we 
gained a common understanding of the entity. We issued detailed referral instructions to the component auditors, reviewed 
and supervised their work through visits to the component auditors during the planning and performance stages of our audit, 
alongside frequent remote communication. Where site visits were not possible, we reviewed audit files remotely. We also 
attended key client briefings on both regional and segment performance.

8. Other information
The other information comprises the information included in the Annual Report, other than the financial statements and our 
Auditor’s Report thereon. The Directors are responsible for the other information contained within the Annual Report.

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.

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 course of 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 this gives 
rise to a material misstatement in the financial statements themselves. 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.

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

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

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

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

Spirent Communications plc Annual Report 2022

FINANCIAL STATEMENTS11. Extent to which the audit was considered capable of detecting irregularities, including fraud
Irregularities, including fraud, are instances of non-compliance with laws and regulations. We design procedures in line with 
our responsibilities, outlined above, to detect material misstatements in respect of irregularities, including fraud. The extent to 
which our procedures are capable of detecting irregularities, including fraud is detailed below. 

11.1. Identifying and assessing potential risks related to irregularities
In identifying and assessing risks of material misstatement in respect of irregularities, including fraud and non-compliance with 
laws and regulations, we considered the following:

•  the nature of the industry and sector, control environment and business performance including the design of the Group’s 

remuneration policies, key drivers for Directors’ remuneration, bonus levels and performance targets;

•  results of our enquiries of management, internal audit and the audit committee about their own identification and assessment 

of the risks of irregularities; 

•  any matters we identified having obtained and reviewed the Group’s documentation of their policies and procedures relating to:

 – identifying, evaluating and complying with laws and regulations and whether they were aware of any instances of 

non-compliance;

 – detecting and responding to the risks of fraud and whether they have knowledge of any actual, suspected or alleged fraud;

 – the internal controls established to mitigate risks of fraud or non-compliance with laws and regulations; and

•  the matters discussed among the audit engagement team, including significant component audit teams, and relevant internal 
specialists, including tax, valuations, pensions and IT regarding how and where fraud might occur in the financial statements 
and any potential indicators of fraud.

As a result of these procedures, we considered the opportunities and incentives that may exist within the organisation for fraud 
and identified the greatest potential for fraud in the area of appropriateness of revenue recognition. In common with all audits 
under ISAs (UK), we are also required to perform specific procedures to respond to the risk of management override.

We also obtained an understanding of the legal and regulatory framework that the Group operates in, focusing on provisions 
of those laws and regulations that had a direct effect on the determination of material amounts and disclosures in the financial 
statements. The key laws and regulations we considered in this context included the Companies Act 2006, the relevant tax 
compliance regulations in the jurisdictions in which the Group operates, Listing Rules and pensions legislation.

In addition, we considered provisions of other laws and regulations that do not have a direct effect on the financial statements 
but compliance with which may be fundamental to the Group’s ability to operate or to avoid a material penalty. These included, 
in particular, considering the effect of the USA’s restrictions on trading with China and the necessity of licenses for various of the 
Group’s products. 

11.2. Audit response to risks identified
As a result of performing the above, we identified the appropriateness of revenue recognition as a key audit matter related to 
the potential risk of fraud. The key audit matters section of our report explains the matter in more detail and also describes the 
specific procedures we performed in response to that key audit matter. 

In addition to the above, our procedures to respond to risks identified included the following:

•  reviewing the financial statement disclosures and testing to supporting documentation to assess compliance with provisions 

of relevant laws and regulations described as having a direct effect on the financial statements;

•  enquiring of management, the audit committee and in-house and external legal counsel concerning actual and potential 

litigation and claims;

•  performing analytical procedures to identify any unusual or unexpected relationships that may indicate risks of material 

misstatement due to fraud;

•  reading minutes of meetings of those charged with governance, reviewing internal audit reports and reviewing 

correspondence with HMRC; and 

•  in addressing the risk of fraud through management override of controls, testing the appropriateness of journal entries and 

other adjustments; assessing whether the judgements made in making accounting estimates are indicative of a potential bias; 
and evaluating the business rationale of any significant transactions that are unusual or outside the normal course of business.

We also communicated relevant identified laws and regulations and potential fraud risks to all engagement team members 
including internal specialists and significant component audit teams and remained alert to any indications of fraud or non-
compliance with laws and regulations throughout the audit.

12. Opinions on other matters prescribed by the Companies Act 2006

In our opinion the part of the Directors’ remuneration report to be audited has been properly prepared in accordance 
with the Companies Act 2006.

In our opinion, based on the work undertaken in the course of the audit:

•  the information given in the Strategic report and the Directors’ report for the financial year for which the financial 

statements are prepared is consistent with the financial statements; and

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

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

13. Corporate Governance Statement
The Listing Rules require us to review the Directors’ statement in relation to going concern, longer-term viability and that part 
of the Corporate Governance Statement relating to the Group’s compliance with the provisions of the UK Corporate Governance 
Code specified for our review.

Based on the work undertaken as part of our audit, we have concluded that each of the following elements of the 
Corporate Governance Statement is materially consistent with the financial statements and our knowledge obtained 
during the audit: 

•  the Directors’ statement with regards to the appropriateness of adopting the going concern basis of accounting and 

any material uncertainties identified set out on page 115;

•  the Directors’ explanation as to its assessment of the Group’s prospects, the period this assessment covers and why 

the period is appropriate set out on page 115;

•  the Directors’ statement on fair, balanced and understandable set out on page 77;

•  the Board’s confirmation that it has carried out a robust assessment of the emerging and principal risks set out on 

page 80;

•  the section of the Annual Report that describes the review of effectiveness of risk management and internal control 

systems set out on page 80; and

•  the section describing the work of the Audit Committee set out on page 78.

14. Matters on which we are required to report by exception
14.1. Adequacy of explanations received and accounting records
Under the Companies Act 2006 we are required to report to you if, in our opinion:

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

•  adequate accounting records have not been kept by the parent Company, or returns adequate for our audit have not 

been received from branches not visited by us; or

•  the parent Company financial statements are not in agreement with the accounting records and returns.

We have nothing to report in respect of these matters.

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

We have nothing to report in respect of these matters.

 Adjusting items comprise amortisation of acquired intangible assets, share-based payment, other adjusting items, tax on adjusting items and any over/under 
provision in respect of prior year tax.

The performance of the Group is assessed using a variety of non-GAAP alternative performance measures which are presented 
to provide additional financial information that is regularly reviewed by management. Adjusting items are identified and excluded 
by virtue of their size, nature or incidence as they do not reflect management’s evaluation of the underlying trading performance 
of the Group. The alternative performance measures are presented on pages 196 and 197. The reported GAAP measures give 
the complete measure of financial performance.

Spirent Communications plc Annual Report 2022

FINANCIAL STATEMENTSNotes to the consolidated financial statements

1. Corporate information 
The Group’s consolidated financial statements for the year ended 31 December 2022 were authorised for issue by the Board 
of Directors on 7 March 2023. Spirent Communications plc is a public limited company incorporated and domiciled in England 
and Wales (registration number 470893). The registered address of the Company is Origin One, 108 High Street, Crawley, 
West Sussex RH10 1BD, United Kingdom. 

The Company’s Ordinary Shares are traded on the London Stock Exchange. 

The Group financial statements have been prepared in accordance with International Accounting Standards in conformity with 
the requirements of the Companies Act 2006 and United Kingdom adopted International Accounting Standards.

The Company has elected to prepare the Company financial statements in accordance with United Kingdom Generally Accepted 
Accounting Practice including Financial Reporting Standard 101 ‘Reduced Disclosure Framework’ (FRS 101) and the Companies Act 
2006. These are presented on pages 172 and 173 and the accounting policies in respect of the Company are set out on pages 174 
to 191. 

2. Significant accounting policies
Accounting convention 
The consolidated financial statements are prepared on a historical cost basis apart from certain financial instruments that have 
been measured at fair value and the United Kingdom defined benefit pension plan obligations which have been measured 
using the projected unit credit method. 

Going concern basis of accounting 
In adopting the going concern basis for preparing the consolidated financial statements, the Directors have considered the 
Group’s principal risks and uncertainties as set out on pages 55 to 60.

The Directors have also considered sensitivities in respect of potential downside scenarios, including stress testing the latest cash 
flow projections that cover a period of 12 months from the date of approval of these consolidated financial statements. In these 
scenarios, the Group has more than sufficient headroom in its available resources.

At 31 December 2022, the Group had cash balances of $209.6 million and external debt only in relation to its lease liabilities. 

The Directors have reviewed the detailed financial projections for the period ending 31 December 2023, as well as the business 
plan and cash flows for the three months ending 31 March 2024. The Directors have also considered the period to the end of 
2025 which forms part of the Group’s longer-term viability assessment. In addition, they have considered the principal risks faced 
by the Group, the sensitivity analysis and the Group’s significant financial headroom and are satisfied that the Group has 
adequate financial resources to continue in operational existence for the foreseeable future, a period of at least 12 months from 
the date of approval of this report. Accordingly, the going concern basis of accounting continues to be used in the preparation 
of the consolidated financial statements.

New accounting standards 
There have been no applicable new standards, amendments to standards and interpretations effective from 1 January 2022 
that have been applied by the Group which have resulted in a significant impact on its consolidated results or financial position. 

Basis of consolidation 
The consolidated financial statements incorporate the financial statements of the Company and its subsidiaries made up to 
31 December each year. The financial statements of subsidiaries are prepared for the same reporting year as the parent 
Company, using consistent accounting policies. A full list of subsidiary undertakings is provided on pages 192 and 193. 

Subsidiary undertakings are entities that are directly or indirectly controlled by the Group. The Group controls an entity when it is 
exposed, or has rights, to variable returns from its involvement with the entity and has the ability to affect those returns through 
its power over the entity. 

Results of subsidiaries are consolidated from the date on which control is transferred to the Group and cease to be consolidated 
from the date on which control is transferred out of the Group. 

The separable net assets, including intangible assets of newly acquired subsidiaries, are incorporated into the consolidated 
financial statements based on their fair values at the effective date of control. 

Spirent Communications plc Annual Report 2022

131

FINANCIAL STATEMENTS2. Significant accounting policies continued 
Basis of consolidation continued 
The Group includes a subsidiary that is operated under the management of a Proxy Board. Details of the Proxy Board arrangements 
and the powers of the proxy holders and Spirent’s management are set out in the Corporate Governance section of this Annual 
Report on page 72. The Directors consider that the Group meets the requirements of IFRS 10 “Consolidated Financial Statements” 
in respect of control over the entity in question as Spirent maintains the following: 

•  rights to appoint, reassign or remove members of key management and the ability to appoint proxy holders and change 

Directors every five years; 

•  rights to direct the investee to enter into, or veto any changes to, transactions; and 

•  decision making rights and rights to direct activities including the ability to change products, territories and customers 

and the ability to terminate product selling (with notice). 

All intra-Group transactions, balances, income and expenses are eliminated on consolidation. 

Business combinations and goodwill 
A business combination is a transaction or other event in which an acquirer obtains control of one or more businesses. Business 
combinations are accounted for using the acquisition method. 

At acquisition date, the identifiable assets acquired and liabilities assumed, including intangible assets, are measured at their 
fair values. The cost of an acquisition is measured as the aggregate of the consideration transferred and the amount of any 
non-controlling interest in the acquiree. Non-controlling interests are measured at the proportionate share of the acquiree’s 
identifiable net assets. 

Contingent consideration resulting from business combinations is valued at fair value at the acquisition date as part of the business 
combination. When the contingent consideration meets the definition of a financial liability, it is subsequently re-measured to fair 
value at each reporting date, with changes in fair value recognised in profit or loss. The determination of fair value is based on 
discounted cash flows. The key assumptions take into consideration the probability of meeting each performance target and 
the discount rate. 

Acquisition related costs are expensed and included in other adjusting items. 

Goodwill arising on the acquisition of subsidiaries, representing the excess of cost over the net fair value of the net assets 
acquired, is capitalised as an intangible asset. Goodwill is carried at cost less any accumulated impairment losses. 

Goodwill is subject to an annual review for impairment. For the purpose of impairment testing, goodwill is allocated to the 
related cash-generating units being the smallest identifiable group of assets that generates cash inflows that are largely 
independent of the cash inflows from other assets or groups of assets. Cash-generating units are grouped and assessed in 
combination where this is consistent with how the chief operating decision maker reviews business performance and at a level 
no larger than an operating segment. Where the recoverable amount of the cash-generating unit is less than its carrying 
amount, including goodwill, an impairment loss is recognised in the income statement. 

Intangible assets 
Intangible assets are carried at cost less accumulated amortisation and accumulated impairment losses. Separately identifiable 
intangible assets such as patent fees, licence fees, trademarks and customer lists and relationships are capitalised on the balance 
sheet only when the value can be measured reliably, or the intangible asset is purchased as part of the acquisition of a business. 
Such intangible assets are amortised over their useful economic lives on a straight-line basis. The carrying value of intangible 
assets is reviewed for impairment if events or changes in circumstances indicate the carrying value may not be recoverable. 

Acquired intangible assets, being customer lists, current technology, databases, brand names and a non-compete covenant, 
are amortised on a straight-line basis over their estimated useful lives and the charge is included within adjusting items in the 
income statement. Licences are amortised over their useful lives or term, and are expensed within cost of sales or selling costs. 

The estimated useful lives of intangible assets and the amortisation expiry dates are as follows: 

Customer lists
Current technology
Brand names
Licences

Useful life Expiry date 

2 to 7 years
5 to 7 years
3 years

FINANCIAL STATEMENTSNotes to the consolidated financial statements continued2. Significant accounting policies continued
Product development 
Research expenditure is charged to product development in the income statement in the year in which it is incurred. Intangible 
assets arising on the Group’s various product development projects are recognised only if the recognition criteria of IAS 38 
“Intangible Assets” are met. 

Product development costs are expensed as incurred until the technological feasibility of the product under development has 
been established. Technological feasibility in Spirent’s circumstances occurs when a working model is completed. For software 
development, technological feasibility is not established until the process of developing the software is complete. After technological 
feasibility is established, additional costs are capitalised and amortised on a straight-line basis over the estimated useful life. 

At 31 December 2022 and 31 December 2021, no amounts have met the recognition criteria. 

Property, plant and equipment 
Property, plant and equipment are stated at cost less accumulated depreciation and accumulated impairment. Depreciation 
is not provided on freehold land. Depreciation is provided to write-off the cost, less estimated residual value, of all other assets 
over their estimated useful lives on a straight-line basis at rates which take into account commercial conditions at their location. 
Usual asset lives are as follows: 

Freehold buildings
Plant and machinery
Fixtures, fittings and equipment: 
- Building installations
- Fittings and equipment
- Motor vehicles
- Business systems software

50 years 
3 to 8 years 

20 years or lease period if lower 
3 to 8 years 
3 to 5 years 
4 years 

Business systems software is capitalised as property, plant and equipment as the software is an integral part of the related hardware. 

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

Impairment of assets 
Intangible assets with finite useful lives, property, plant and equipment and right-of-use assets are tested for impairment at each 
reporting date where there is an indication that an asset may be impaired. Goodwill and intangible assets with an indefinite useful 
life are assessed at least annually. When an impairment test is performed, the recoverable amount is assessed by reference to the 
higher of the net present value of the expected cash flows (value in use) of the relevant cash-generating unit or asset and the fair 
value less cost of disposal. In assessing value in use, the estimated future cash flows are discounted to their present value using 
a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. 
Where the carrying amount of an asset exceeds its recoverable amount, the asset is considered impaired and is written down 
to its recoverable amount. Impairment losses are recognised in the income statement in those expense categories consistent 
with the function of the impaired asset. 

Where an impairment loss has been recognised against an asset, it may be reversed in future periods where there has been 
a change in the estimates used to determine the asset’s recoverable amount since the last impairment loss was recognised, 
but only to the extent that the asset’s carrying amount does not exceed the carrying amount that would have been determined, 
net of depreciation or amortisation, had no impairment loss been recognised in prior years. Such a reversal is recognised in the 
income statement. This does not apply for goodwill, for which an impairment loss must not be reversed in any circumstances. 

Leases 
The Group as a lessee
The Group assesses whether a contract is or contains a lease, at inception of a contract. A contract is, or contains, a lease if 
the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. 

The Group recognises a right-of-use asset and a corresponding lease liability with respect to all lease agreements in which it is 
the lessee at the commencement date of the lease (i.e. the date the underlying asset is available for use), except for short-term 
leases (defined as leases with a lease term of 12 months or less) and leases of low-value assets. For these leases, the Group recognises 
the lease payments as an operating expense within the income statement on a straight-line basis over the period of the lease.

At the commencement date of the lease, the lease liability is initially measured at the present value of lease payments to be 
made over the lease term, discounted using the rate implicit in the lease. If this rate cannot be readily determined, the Group 
uses its incremental borrowing rate. Under the modified retrospective transition method, which is the method that the Group 
adopted on transition to IFRS 16 “Leases” on 1 January 2019, lease liabilities are required to be discounted using the incremental 
borrowing rate at date of transition. The Group has set the discount rate based upon the local base rate with an additional 
premium to reflect various factors such as credit risk. This approach enables an appropriate rate to be set for each lease 
depending on geographic location and lease classification.

FINANCIAL STATEMENTS2. Significant accounting policies continued
Leases continued
The Group as a lessee continued
The lease payments include fixed payments (including in-substance fixed payments) less any lease incentives receivable, 
variable lease payments that depend on an index or rate, and amounts expected to be paid under residual value guarantees. 
The lease payments also include the exercise price of a purchase option reasonably certain to be exercised by the Group 
and payments of penalties for terminating a lease, if the lease term reflects the Group exercising the option to terminate. 
The variable lease payments that do not depend on an index or a rate are recognised as an expense in the period in which 
the event or condition that triggers the payment occurs. 

The lease liability is presented as a separate line in the consolidated balance sheet. 

The lease liability is subsequently measured by increasing the carrying amount to reflect interest on the lease liability (using the 
effective interest method), and by reducing the carrying amount to reflect the lease payments made. It is re-measured when 
there is a change in future lease payments arising from a change in an index or rate, if the Group changes its assessment of 
whether it will exercise a purchase, extension or termination option or if there is a modification. Interest on the lease liability is 
presented within finance costs in the income statement. 

When the lease liability is re-measured in this way, a corresponding adjustment is made to the carrying amount of the right-of-use 
asset, or is recorded in profit or loss if the carrying amount of the right-of-use asset has been reduced to zero. 

The right-of-use asset is initially measured at cost, which comprises the initial amount of the corresponding lease liability, 
adjusted for any lease payments made at or before the commencement date, plus any initial direct costs incurred and an 
estimate of costs to dismantle and remove the underlying asset or to restore the underlying asset or the site on which it is 
located, less any lease incentives received. 

The right-of-use asset is subsequently depreciated using the straight-line method from the commencement date to the earlier 
of the end of the useful life of the right-of-use asset or the end of the lease term. In addition, the right-of-use asset is periodically 
reduced by impairment losses, if any, and adjusted for certain re-measurements of the lease liability.

The right-of-use assets are presented as a separate line in the consolidated balance sheet. 

Lease payments for short-term leases, lease payments for low-value assets and variable lease payments not included in the 
measurement of the lease liability are classified as cash flows from operating activities within the consolidated cash flow 
statement. The Group has classified the principal and interest portions of lease payments within financing activities.

The Group as a lessor 
When the Group acts as a lessor, it determines at lease inception whether each lease is a finance lease or operating lease.

To classify each lease, the Group makes an overall assessment of whether the lease transfers substantially all of the risks and 
rewards incidental to ownership of the underlying asset. If this is the case, then the lease is a finance lease; if not, then it is an 
operating lease.

The Group subleases certain of its buildings where the subleases are classified as finance leases. In these instances, the Group 
derecognises the right-of-use asset on the head lease at the sublease commencement date and continues to account for the 
original lease liability in accordance with the lessee accounting model. The Group, as a sublessor, recognises a net investment in 
the sublease within trade and other receivables in the balance sheet and evaluates it for impairment. The net investment in the 
sublease is subsequently measured by increasing the carrying amount to reflect interest (using the effective interest method), 
and by reducing the carrying amount to reflect sublease income received. Interest on the net investment in the sublease is 
presented within finance income in the income statement. 

Cash flows from the principal and interest of the finance lease receivables received are classified as investing activities within the 
consolidated cash flow statement. 

Inventories 
Inventories are stated at the lower of cost and estimated net realisable value, after provisions for obsolescence. Cost includes 
all costs incurred in bringing each product to its present location and condition, being the full manufacturing cost on a first-in, 
first-out basis, including all attributable overheads based on a normal level of activity. 

Provisions 
Provisions are recorded when the Group has a present, legal or constructive obligation as a result of a past event, for which it is 
probable that the Group will be required to settle by an outflow of resources and for which a reliable estimate of the amount of 
the obligation can be made. Provisions are reviewed at each balance sheet date and adjusted to reflect the current best estimate. 

Where the effect of the time value of money is material, the amount of the provision shall be the present value of the expenditures 
expected to be required to settle the obligation.

FINANCIAL STATEMENTSNotes to the consolidated financial statements continued2. Significant accounting policies continued
Contingent liabilities 
Contingent liabilities are possible obligations whose existence will be confirmed only on the occurrence or non-occurrence of 
uncertain future events outside the Group’s control, or present obligations that are not recognised because it is not probable 
that a settlement will be required or the value of such a payment cannot be reliably measured. The Group does not recognise 
contingent liabilities but discloses them. 

Foreign currencies 
The consolidated financial statements are presented in US Dollars, which is the Group’s presentation currency. 

Transactions in foreign currencies are initially recorded at the rates ruling at the date of the transaction. Monetary assets 
and liabilities denominated in foreign currencies are retranslated at the rates ruling at the balance sheet date. All exchange 
differences are taken to the consolidated income statement. Non-monetary assets and liabilities denominated in foreign 
currencies are measured in terms of historical costs using the exchange rate at the date of the initial transaction. 

The functional currencies of the Group’s operations are principally US Dollar, Pound Sterling or Euro. On consolidation, the assets 
and liabilities of the Group’s foreign operations are translated into the Group’s presentation currency at exchange rates ruling 
at the balance sheet date. The results of foreign operations are translated into US Dollars using average rates for the period. 
The exchange differences arising on retranslation are classified as a separate component of equity, the translation reserve. 
Such translation differences are recognised as part of the profit or loss on disposal should an operation be disposed of. 

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

Trade receivables 
Trade receivables are non-interest bearing and are stated at original invoiced amount less an appropriate allowance for expected 
credit losses. At each reporting date, the Group measures the loss allowance at an amount equal to the lifetime expected credit losses. 

The Group applies the IFRS 9 simplified approach to measuring expected credit losses which uses a lifetime expected loss 
allowance for all trade receivables. Therefore, the Group does not track changes in credit risk, but instead recognises a loss 
allowance based on lifetime expected credit losses at each reporting date. To measure the expected credit losses, the Group 
has established a provision matrix that is based on shared credit risk characteristics and the days past due based on the 
expected loss rates. 

The provision matrix is initially based on payment profiles of trade receivables over a period of 12 months before 31 December of 
the prior year and the corresponding historical credit losses experienced within this period. At every reporting date the historical 
observed default rates are updated. The Group also considers the impact of regional macroeconomic factors on the likelihood 
of future losses. 

Trade receivables are written off when there is no reasonable expectation of recovery. 

A default on a trade receivable occurs when the debtor fails to make contractual payments when they fall due. 

Cash and cash equivalents 
Cash and cash equivalents in the balance sheet comprise cash at bank and in hand and short-term deposits which have an 
original maturity of three months or less. For the purposes of the consolidated cash flow statement, cash and cash equivalents 
consist of cash and cash equivalents as defined above. There are no bank overdrafts. 

Trade payables 
Trade payables are non-interest bearing and are stated at the original invoiced amount. 

Equity instruments 
Equity instruments are recorded at the proceeds received, net of direct issue costs. Spirent Communications plc Ordinary Shares 
held by the Group are classified in equity as treasury shares and are recognised at cost and included as a deduction from 
retained earnings. Consideration received for the sale of such treasury shares is also recognised in equity. 

Derivative financial instruments 
The Group uses forward foreign currency exchange contracts to manage exposures arising on receipts and payments in foreign 
currencies relating to firm commitments. 

Forward foreign currency exchange contracts are initially recognised at fair value on the date on which the contract is entered 
into and are subsequently re-measured to fair value at each reported balance sheet date. The fair value of forward foreign 
currency exchange contracts is calculated by reference to current forward exchange rates for contracts with similar maturity 
profiles. The Group has not adopted the hedge accounting rules. Consequently all gains and losses arising from changes in fair 
value are taken to the income statement.

FINANCIAL STATEMENTS2. Significant accounting policies continued
Retirement benefits 
The Group operates two funded defined benefit pension plans which are in the United Kingdom; all other pension plans are 
defined contribution in nature. For the defined contribution plans, the amount charged to the income statement is the employer’s 
contributions paid or payable during the year. 

For defined benefit pension plans, full actuarial valuations are carried out every three years using the projected unit credit method 
and updates are performed at each balance sheet date. Re-measurement, comprising actuarial gains and losses, the effect of 
changes to the asset ceiling (if relevant) and the return on plan assets (excluding interest), is reflected immediately in the balance 
sheet surplus with a charge or credit recognised in other comprehensive income in the period in which they occur. Re-measurement 
recognised in other comprehensive income will not be reclassified to profit or loss. Past service cost is recognised in profit or loss 
in the period of plan amendment. Net interest is calculated by applying the discount rate at the beginning of the period to the 
net defined benefit pension asset, taking account of any changes in the net defined benefit pension asset during the period as a 
result of contribution and benefit payments. Where a refund of a surplus is expected, any applicable taxes that are not income in 
nature are netted off. Defined benefit pension costs are categorised as: 

•  service cost (including current service cost, past service cost and gains and losses on curtailments or settlements); 

•  net interest expense or income; and 

•  re-measurement. 

The Group presents the first two components of defined benefit pension costs in profit or loss. 

The Group also operates a deferred compensation plan in the United States. The plan has elements of a defined benefit pension 
retirement obligation and therefore is required to be valued in accordance with IAS 19 “Employee Benefits”. For the deferred 
compensation plan, the gains or losses on the deemed investments that are attributed to the deferral account over time are 
charged or credited to the income statement whereas the re-measurement, comprising actuarial gains or losses, is reflected 
immediately in the balance sheet liability with a charge or credit in other comprehensive income in the period in which it occurs. 
Re-measurement recognised in other comprehensive income will not be reclassified to profit or loss. 

Revenue 
Revenue represents the transfer of promised products or services to customers in an amount that reflects the consideration to 
which the Group expects to be entitled in exchange for those products or services. 

Revenue from product sales of hardware and perpetual software licences is recognised at the point in time when the customer 
has obtained control of the products sold. This is usually when the products have been delivered in accordance with the contractual 
terms. In some instances it is not until acceptance has occurred that control of the asset is transferred to the customer. Terms of 
acceptance are dependent upon the specific contractual arrangement agreed with the customer. If it can be objectively 
determined that control has been transferred to the customer in accordance with the agreed contract specifications, customer 
acceptance is a formality that would not affect the determination of when the customer has obtained control of the products. 
However, if it cannot be objectively determined that the products delivered are in accordance with the agreed-upon contract 
specifications, revenue would not be recognised until customer acceptance has been granted. 

For sales of software licences, the Group determines whether the licence is capable of being distinct and is separately 
identifiable from other promises in the context of the contract. Revenue from software subscription licences that provide the 
customer with a right to access the Group’s intellectual property throughout the subscription period is recognised over time, 
throughout the subscription period. Revenue from perpetual software licences that provide the customer with a right to use the 
Group’s intellectual property for an indefinite period of time is recognised at the point in time when the customer can first use 
and benefit from the software.

For the sale of services, revenue is generally recognised over time with reference to when or as the performance obligations are 
satisfied by transferring the service to the customer. Revenue from support and maintenance service contracts and software 
subscription sales is recognised over the period of performance on a straight-line basis. 

Revenue from professional services is generally recognised as work progresses in accordance with agreed-upon contractual 
terms, based on a measure of progress towards complete satisfaction of the performance obligation. Progress is measured 
using either an output method (e.g. completion of a day, or for fixed price contracts revenue is recognised based on performance 
completed or contractual milestones reached) or an input method (e.g. actual cost of services provided as a proportion of total 
cost of services expected to be provided under the contract). Where applicable, the Group elects to use the practical expedient 
where revenue can be recognised in the amount to which the Group has a right to invoice, only if the Group has a right to 
consideration from a customer in an amount that corresponds directly with the value to the customer of the Group’s performance 
completed to date. Where the Group’s professional services contracts contain terms of acceptance, revenue would not be 
recognised until customer acceptance had been obtained. Where the professional service has a pre-determined or fixed output 
deliverable, revenue is recognised at a point in time once the performance obligation has been satisfied and the customer has 
received the agreed deliverable.

FINANCIAL STATEMENTSNotes to the consolidated financial statements continued2. Significant accounting policies continued
Revenue continued
The Group accounts for multi-component orders as multiple performance obligations if the following criteria are met:

a) 

b) 

 the good or service is capable of being distinct, that is, they are individually readily available and regularly sold separately 
to customers; and

 the promise to transfer the good or service is distinct in the context of the contract, that is, they do not require significant 
integration, customisation or modification with other goods or services in the contract and are not highly interrelated or 
interdependent of other goods or services in the contract.

For multi-component orders where the elements are accounted for as multiple performance obligations, the transaction price 
and discount, if any, are allocated proportionally to all performance obligations in the contract. If either of the two criteria above 
are not met, and where various components in the contract are combined, bundled or pre-assembled into one or more product 
or equipment units to form a distinct good or service, they will be accounted for as a single performance obligation. 

Virtually all of the Group’s revenue is derived from the sale of its own products and services. In the instances where the Group is 
a reseller of third party products and services, it accounts for these transactions as a principal as it controls the product or service 
before it is transferred to the customer and therefore recognises revenue on a gross basis.

Cost of sales 
The Group’s cost of sales related to the sale of its products includes materials, payments to third party contract manufacturers, 
royalties and salaries and other expenses related to its manufacturing and supply operations personnel. Cost of sales related to 
the provision of services includes salaries and other expenses associated with technical support services and the cost of 
extended maintenance services. 

Costs to obtain a contract 
The incremental costs of obtaining a contract with a customer are capitalised as an asset if the Group expects to recover them. 
The Group incurs costs such as sales commissions when it enters into a new contract. Such costs are presented in the consolidated 
balance sheet as assets recognised from costs to obtain a contract where the related revenue is recognised over time, usually in 
relation to support and subscription agreements. These assets are amortised on a systematic basis consistent with how the related 
revenue is recognised. The amortisation is recognised in selling and marketing costs within the income statement. 

The Group applies the practical expedient in paragraph 94 of IFRS 15 and recognises incremental costs of obtaining a contract as an 
expense when incurred if the amortisation period of the asset that the Group would otherwise have recognised is one year or less. 

Management is required to determine the recoverability of assets recognised from costs to obtain a contract. At each reporting 
date, the Group determines whether or not the assets are impaired by comparing the carrying amount of the asset to the 
remaining amount of consideration that the Group expects to receive less the costs that relate to providing services under the 
relevant contract. No assets were impaired as at 31 December 2022 or 31 December 2021.

Deferred income 
Deferred income is only recognised on non-cancellable contracts that provide unconditional rights to payment from the customer 
for products and services that the Group has not yet completed providing or that it will provide in the near future. 

Revenue from product sales of hardware and perpetual software licences is recognised at the point in time when the customer 
has obtained control of the products sold. In the instances where the customer has been invoiced and revenue from hardware 
or perpetual software licences is unable to be recognised, revenue would not be recognised until control has passed, resulting 
in deferred income. 

Support services and software subscription agreements are generally billed at commencement of the support or subscription 
contract, while revenue is recognised over the period of the support or subscription agreement, resulting in deferred income. 

The Group occasionally receives advance payments from customers on account, before products or services are delivered and 
revenue is recognised, resulting in liabilities. 

Deferred income and payments received on account are reported on the consolidated balance sheet within contract liabilities 
on a contract-by-contract basis at the end of each reporting period.

Government grants 
A government grant is recognised in the balance sheet initially within trade and other payables when there is reasonable assurance that 
it will be received and that the Group will comply with the conditions attached to it. Grants that compensate the Group for expenses 
incurred are recognised as other operating income on a systematic basis in the same periods in which expenses are incurred. 

Spirent Communications plc Annual Report 2022

FINANCIAL STATEMENTS2. Significant accounting policies continued
Employee benefits 
When an employee has rendered services to the Group during an accounting period, short-term benefits expected to be paid 
in exchange for those services are recognised in the same accounting period. 

Share-based payment 
The Group operates various equity-settled and cash-settled share-based compensation plans and accounts for these awards 
in accordance with IFRS 2 “Share-based Payment” 

For equity-settled awards, the fair value is recognised in the income statement on a straight-line basis over the vesting period 
together with a corresponding change in equity. The fair value is measured using the Black-Scholes model by reference to the 
share price, and taking into account the terms and conditions of the award, excluding non-market vesting conditions, at the date 
the awards were granted. The charge is reassessed at each balance sheet date to reflect the expected and actual levels of vesting, due 
to achievement or otherwise of non-market conditions. Awards where vesting is conditional upon satisfying a market condition or 
non-vesting condition are treated as vesting irrespective of whether the market or non-vesting condition has been satisfied. 

Cash-settled awards are measured at fair value at the balance sheet date. The Group recognises a liability within trade and 
other payables at the balance sheet date based on these fair values, taking into account the estimated number of options that 
will actually vest and the relative completion of the vesting period. Changes in the value of this liability are recognised in the 
income statement for the year.

With effect from 1 January 2019, one-third of the Annual Incentives of the Executive Directors was deferred into shares for a 
period of three years. This amount is an equity-settled share-based payment transaction within the scope of IFRS 2 and the 
related expense is charged to the income statement in the same year as the measurement period. This amount has been 
charged to administration expenses in the income statement and forms part of adjusted operating profit as it reflects part 
of the underlying trading performance of the Group. 

The Group has an employee share trust for the granting of certain share incentives to employees. Shares in the Group held 
by the employee share trust are treated as treasury shares and presented in the balance sheet as a deduction from equity. 

Tax 
Income tax on the profit or loss for the year comprises current and deferred tax. Income tax is recognised in the income 
statement except to the extent that it relates to items in other comprehensive income or equity. 

Current tax is the expected tax payable on the taxable income for the year, using tax rates enacted or substantively enacted 
at the balance sheet date, and any adjustments to tax payable for previous years. 

Deferred tax is recognised on all temporary differences arising between the tax bases of assets and liabilities and their carrying 
amounts in the financial statements, with the following exceptions: 

•  where the temporary difference arises from the initial recognition of goodwill (taxable temporary differences only) or of an 

asset or liability in a transaction that is not a business combination that at the time of the transaction affects neither accounting 
nor taxable profit or loss; and 

•  in respect of taxable temporary differences associated with investments in subsidiaries, where the timing of the reversal of the 
temporary differences can be controlled and it is probable that the temporary differences will not reverse in the foreseeable future. 

A deferred tax asset is recognised only to the extent that it is probable that taxable profits will be available against which the 
deductible temporary differences, carried forward tax credits or tax losses can be utilised. 

Deferred tax assets and liabilities are measured on an undiscounted basis at the tax rates that are expected to apply when the related 
asset is realised or the liability is settled, based on tax rates and laws enacted or substantively enacted at the balance sheet date. 

Dividends paid 
The interim dividend is included in the financial statements in the period in which it is paid, and the final dividend and the special 
dividend are included in the period in which they are approved by the shareholders at an Annual General Meeting.

FINANCIAL STATEMENTSNotes to the consolidated financial statements continued2. Significant accounting policies continued
Adjusting items 
Adjusting items are disclosed separately in the income statement where it is necessary to do so due to their nature or amount 
and to provide further understanding of the Group’s financial performance. Adjusting items comprise amortisation of acquired 
intangible assets, share-based payment and other adjusting items, the tax effect of these items and any over/under provision 
of tax in the prior year.

The Group excludes share-based payment from adjusted operating profit (except for share-based payment relating to the 
Executive Directors’ deferred bonus plan, see share-based payment policy), as the expense can fluctuate based on the size, 
nature and timing of awards granted, the Group’s share price and the subjective assumptions used in the calculation. 
Management consider the financial results of the business before the deduction of share-based payment for their operational 
decision making. Additionally, management believes the exclusion of share-based payment also allows for more meaningful 
comparisons of operating results with peer companies, many of which also exclude the expense from underlying results.

Certain items are classified as other adjusting items due to their nature, amount or infrequency. Such presentation is relevant to 
further understanding of the Group’s financial statements. These items are not part of the Group’s normal ongoing operations. 
Costs directly associated with the integration of a business acquisition are included within other adjusting items to the extent they 
are in accordance with the above definition.

Direct transaction costs and fees of potential or actual acquisitions are charged to the income statement in the period in which 
they are incurred. Such items are presented separately as other adjusting items and, due to their nature and infrequency, are 
excluded from the underlying trading performance of the Group.

Adjusting items are disclosed within administration expenses in the consolidated income statement as they are reviewed, 
managed and controlled centrally by the Group. The Group considers these costs to be functionally aligned to, and have 
therefore been presented alongside, corporate costs within administration expenses. This presentation is relevant to an 
understanding of the Group’s financial performance. 

Critical accounting judgements and key sources of estimation uncertainty
The preparation of financial statements requires the Group to make estimates and assumptions that affect items reported. 
Such estimates and assumptions are based on management’s best knowledge of current facts, circumstances and future events. 
Actual results may differ, possibly significantly, from those estimates. The areas requiring a high degree of judgement or where 
assumptions and estimates are significant to the consolidated financial statements are discussed below. 

Estimates 
Recognition of deferred tax assets 
The recognition of deferred tax assets is based upon whether it is more likely than not that there will be sufficient and suitable 
taxable profits in the relevant legal entity or tax group against which to utilise the assets in the future. The extent to which 
deferred tax assets can be recognised is based on current forecasts and estimates prepared by management. A change to 
these forecasts and estimates could result in a different recognition outcome. Judgement is required when determining probable 
future taxable profits, which are estimated using the latest available profit forecasts. Unrecognised deferred tax assets are 
disclosed in note 26.

2. Significant accounting policies continued
Critical accounting judgements and key sources of estimation uncertainty continued
Judgements 
Revenue recognition 
The transaction price is allocated to each performance obligation on a relative standalone selling price basis. Where there are 
no observable prices, the Group generally determines the standalone selling prices of individual elements based on standalone 
internal list prices which are then subject to discount.

To determine the appropriate revenue recognition for contracts containing multiple elements or complex solutions that include 
both products and services, we evaluate whether the contract should be accounted for as a single or multiple performance 
obligation. This evaluation requires significant judgement and impacts the amount of revenue allocated to each performance 
obligation, which can affect the amount of revenue recognised and deferred income on the balance sheet. 

The factors the Group considers when making this judgement are as follows:

•  whether the elements of a multi-component order have a unique part number as evidenced in our product lifecycle 

management process;

•  whether the elements of a multi-component order have a standalone selling price as evidenced in our internal price list;

•  whether the elements of a multi-component order are regularly sold separately to a range of customers, based on historical information; 

•  whether the customer can benefit from the elements of a multi-component order on their own or with resources that are 

readily available to the customer, based on technical input from our product managers; 

•  whether the elements of a multi-component order require significant integration, modification or customisation with other elements 

of the multi-component contract, based on historical information and technical input from our product managers; and 

•  whether the elements of a multi-component order are significantly affected by one or more of the other elements of the multi-component 

contract and whether there is a significant two-way dependency, based on technical input from our product managers.

For professional services revenue recognised over time, a single method of measuring progress is selected and used for each 
performance obligation. The selection of the method to measure progress towards completion requires judgement and is based 
on the nature of the services to be provided. The selected method is applied consistently to similar contracts in similar circumstances. 
This judgement impacts revenue recognised over time and the amount of deferred income on the balance sheet.

Leases 
The Group exercises judgement in determining whether it is reasonably certain that a building lease extension or termination 
option will be exercised. This will take into account the length of time remaining before the option or extension is exercisable, 
current trading, future trading forecasts and the level and type of future capital investment expected to be made. The Group 
assesses at lease commencement whether it is reasonably certain to exercise the extension options. The Group reassesses whether 
it is reasonably certain to exercise the options if there is a significant event or significant change in circumstances within its control. 
This judgement impacts the carrying amounts of right-of-use assets and lease liabilities. 

Defined benefit pension plans
For the Staff Plan defined benefit pension scheme, the Group recognises a net pension scheme surplus as it is expected the liabilities 
will be settled over time until the last beneficiary dies and the residual surplus in the scheme can be refunded to the Group as sponsor. 

The scheme Trustees only have the ability to augment benefits when the scheme is in a wind up, and it is expected they would 
seek the support of the Company in any case. As the scheme cannot enter wind up without the support of the Company and the 
intention today is not to enter into wind up until the death of the final beneficiary, this is not seen as a condition to the Group 
receiving a refund. As the refund would attract withholding tax of 35 per cent the surplus has been reduced by this amount.

These assumptions require judgement and affect the amount of scheme surplus recognised and whether to recognise a surplus at all. 

Applicable new standards and interpretations not applied 
The IASB and IFRIC have issued the following standards and interpretations with an effective date for the Group after the date 
of these financial statements: 

International Accounting Standards (IAS/IFRS)

Disclosure of Accounting Policies (Amendments to IAS 1 and IFRS Practice Statement 2)
IAS 8  Definition of Accounting Estimates (Amendments to IAS 8)
IAS 1  Classification of Liabilities as Current or Non-Current (Amendments to IAS 1)

Effective for annual periods 
beginning on or after 

1 January 2023
1 January 2023
1 January 2024

The Directors do not anticipate that the adoption of these standards and interpretations will have a material impact on the 
Group’s financial statements in the period of initial application.

FINANCIAL STATEMENTSNotes to the consolidated financial statements continued3. Operating segments  
The Group’s organisational structure is based on differences in the products and services offered by each segment and 
information regularly reviewed by the Group’s Chief Executive Officer, its chief operating decision maker, is presented on 
this basis. The Group’s operating segments follow this structure. 

The Group’s reportable operating segments are Lifecycle Service Assurance and Networks & Security. The Group evaluates 
adjusted operating profit before acquired intangible asset amortisation, share-based payment and other adjusting items. 
Finance income and finance costs are not allocated to the reportable segments. Corporate is not an operating segment and 
costs are separately reported and not allocated to the reportable segments. Information on segment assets and segment 
liabilities is not regularly provided to the Group’s Chief Executive Officer and is therefore not disclosed below. There is no 
aggregation of operating segments. 

The Group disaggregates revenue from contracts with customers by nature of products and services and primary geographical 
markets as this best depicts how the nature, amount, timing and uncertainty of the Group’s revenue and cash flows are affected 
by economic factors.

All of the Group’s revenue arose from contracts with customers. Generally, revenue from the sale of hardware and software 
is recognised at a point in time and revenue from maintenance and support services is recognised over time. 

Europe, Middle East and Africa includes United Kingdom revenue of $14.1 million (2021 $12.3 million). 

Americas includes United States revenue of $317.3 million (2021 $305.6 million). 

Asia Pacific includes China revenue of $110.9 million (2021 $102.8 million). 

Revenues are attributed to regions and countries based on customer location. 

No one customer accounted for 10 per cent or more of total Group revenue in 2022. One customer accounted for 10 per cent of 
total Group revenue in 2021, amounting to $57.8 million. Approximately 92 per cent of this revenue was in the Lifecycle Service 
Assurance operating segment.

In 2021, the Group commenced implementation of a global R&D engineering plan which will rationalise the number of sites and 
extend our flexibility to serve our global customers, incurring $1.2 million of costs comprising employee severance and set up 
costs. This plan continued into 2022 where $1.5 million was incurred in relation to retention payments and facility and team set 
up costs. The plan will conclude in 2023.

FINANCIAL STATEMENTS5. Other adjusting items continued 
On 4 March 2021, the Group completed the acquisition of octoScope, Inc. Acquisition related performance payments of $0.6 million 
and $0.8 million in relation to post acquisition integration were incurred during 2021. During 2022, $0.1 million was credited to 
other adjusting items in relation to post acquisition performance payments and $0.3 million was incurred in relation to post-
acquisition integration. The acquisition related performance payments to key employees of the former octoScope business are 
contingent on meeting revenue growth targets for 2021 and 2022 and/or a continuing employment requirement and comprise 
$0.4 million (2021 $0.9 million) in respect of retention bonuses offset by $0.5 million (2021 $0.3 million) relating to a remeasurement 
of the contingent consideration liability recognised on acquisition. In addition, direct transaction related costs of $0.6 million 
(2021 $1.9 million) were incurred comprising adviser fees. See note 33 for further details. 

The Group commenced a strategic evaluation in 2022 incurring employee separation costs of $1.3 million. This programme 
includes a number of initiatives designed to reshape the business to maximise market opportunities by focusing on larger 
bundled solutions sales and service-led engagements that address our customers’ most pressing business challenges. These 
include enhancement of the leadership team to include some important new roles such as a Chief Information Officer, a Chief 
Marketing Officer and development of our sales and marketing organisation. This programme will continue into 2023 with total 
anticipated costs of $3-4 million. 

The tax effect of other adjusting items is a credit of $0.9 million (2021 $1.1 million). There will be a total net cash outflow of $3.6 million 
in respect of other adjusting items charged in 2022, $1.7 million of which was in 2022 (2021 $4.4 million outflow with $3.5 million paid 
in 2021). The cash outflow in 2022 in respect of other adjusting items charged in 2021 was $0.9 million (2021 $0.5 million).

The total cash outflow in respect of other adjusting items is reported within cash flows from operating activities in the 
consolidated cash flow statement.

FINANCIAL STATEMENTSNotes to the consolidated financial statements continued9. Pensions 
Defined benefit plans 
i) Characteristics and risks associated with the Plans 
The Group sponsors two funded defined benefit pension plans in the United Kingdom: the Spirent Communications plc Staff Pension 
& Life Assurance Plan (“Staff Plan”) and the Spirent Communications plc Retirement Cash & Life Assurance Plan (“Cash Plan”). These plans 
are funded and have full UK HM Revenue & Customs (“HMRC”) tax-exempt approval. Both schemes are administered by a Trustee 
board which is comprised of representatives from the employer, member nominated Trustees and an independent Trustee. The 
Trustee board operates in accordance with the Trust Deed and Rules of each Plan and acts in the interests of all of its members. 

•  The Staff Plan is the Group’s most significant plan, and it provides its members with retirement benefits based on their final 

salary and length of service. The Staff Plan is closed to new entrants. 

•  The Cash Plan is complicated with multiple cohorts that allows members to benefit from a lump sum on retirement, a defined 

benefit contribution with a defined benefit underpin or pension. The Cash Plan is closed to new entrants.

There is also a UK unfunded plan, which consists of a contractual obligation for the Group to top up certain former employees’ 
benefits whose salaries exceeded the statutory earnings cap. 

As with the vast majority of similar arrangements in the United Kingdom, the Group ultimately underwrites the risks relating to 
the defined benefit plans. These risks include investment risks and demographic risks, such as the chance of members living 
longer than expected. 

The Cash Plan holds a significant proportion of its assets in equity. Strong future equity returns would be expected to reduce the 
Group’s future cash contributions (and vice versa). 

The latest triennial actuarial valuations dated 31 March 2021 indicated a combined funding deficit of £11.5 million, calculated on a 
technical provisions basis using more prudent assumptions than the accounting valuation, particularly in relation to the discount 
rate inflation and demographic. A deficit reduction plan was agreed with the trustees which required the Company to pay 
monthly contributions of £449,609, whilst a funding deficit remains, increasing in line with CPI each year. In September 2022, this 
deficit funding plan was suspended whilst the Group and trustees worked together to consider the feasibility of purchasing a bulk 
annuity insurance policy.

In October 2022, the Trustees with the Company’s support, purchased a bulk annuity insurance policy from specialist UK insurer 
Pension Insurance Corporation (PIC), in respect of the largest plan, the Staff Plan. The premium was met from the plan’s assets 
and sufficient assets remain to meet the plan’s ongoing costs. This pension buy-in secures an insurance asset from PIC that 
matches the remaining pension liabilities of the Staff Plan, such that the Company no longer bears any investment, inflation, 
longevity or other demographic risks. An asset remeasurement loss of $7.4 million has been recorded in other comprehensive 
income as the premium paid was greater than the IAS 19 accounting value of the corresponding liabilities. Following the 
purchase of the bulk annuity insurance policy, the Group does not expect to make any further cash contributions to this plan. 
Cash contributions to the plan in 2022 amounted to $1.1 million (£0.9 million) (2021 $7.3 million (£5.4 million)).

At 31 December 2022, a reserve of $3.6 million (£3.0 million) is included within the accounting position in respect of equalising 
historic GMP benefits. The ultimate cost to equalise benefits could be higher or lower than reserved (but not materially so), 
reflecting the considerable uncertainty in the way in which benefits will ultimately be equalised. The bulk annuity insurance policy 
purchased by the trustees does not currently include provision for equalising GMPs but there is a mechanism for them to do so 
once finalised. As updates are made the reserve the difference will be charged to other comprehensive income as an 
experience gain/loss.

The Group also operates an unfunded deferred compensation plan for employees in the United States. The plan enables 
participating employees to defer a portion of their salary and invest it in deemed investments, which are used to measure 
the gains or losses that are attributed to the deferral account over time. The plan has elements of a defined benefit pension 
retirement obligation and therefore is required to be valued in accordance with IAS 19.

FINANCIAL STATEMENTSNotes to the consolidated financial statements continued9. Pensions continued
Defined benefit plans continued
ii) Amounts in the financial statements continued
a) The assets and liabilities in each plan continued
In 2021, approximately 60 per cent of the Staff Plan’s assets were held in a combination of LDI funds and cash benchmarked 
bonds. The objective of this allocation was to hedge against the plan’s liabilities, provide protection against inflation risk and 
provide a level of investment returns in all market scenarios. 

These funds have a wide investment remit and as such the investments of the funds may or may not be listed on recognised 
exchanges and markets and will be without restriction as to geographical, industrial or sectoral exposure. These funds may take both 
long and short positions and may utilise a broad range of derivatives. The funds’ investments may include sub-investment grade 
securities, corporate debt securities, gilts, sale and repurchase agreements, loans, and emerging markets debt and currencies. 

The plans are prohibited from investing in Spirent’s own financial instruments. 

The fair values of the quoted equity and debt instruments are determined based on quoted market prices in active markets 
whereas the fair values of the other assets are not. Unquoted investments are included at values provided by the fund managers 
and are generally valued using recent market data and external sources, with a hierarchy that follows the principles of IFRS 13 
“Fair Value Measurement”. 

The Group has determined that it has an unconditional right to refund of surplus assets if the schemes are run off until the last 
member dies, on which basis IFRIC 14 does not cause any change in the balance sheet disclosures before tax. 

For the purposes of the following disclosures the Staff Plan and Cash Plan have been combined as the Cash Plan is immaterial

The $104.8 million loss on remeasurement of plan assets represents a $95.9 million reduction in asset values prior to the buy-in 
(the assets were invested to match the liability risk profile which also reduced significantly as interest rates rose), a $7.4 million 
loss due to the premium on buy-in exceeding the IAS 19 liability measure, a $2.5 million loss as the asset returns on the Cash Plan 
were lower than assumed under IAS 19 offset by a $1.0 million gain as the Staff Plan asset returns exceeded those assumed 
under IAS 19.

f) The key financial assumptions 
The assumptions used for both plans using a weighted average were as follows: 

Inflation – RPI
Inflation – CPI (pre-2030)
Inflation – CPI (post-2030)
Rate of increase in pensionable salaries
Rate of increase for pensions in payment pre-2001 service
Rate of increase for pensions in payment 2001 to 5 April 2005 service
Rate of increase for pensions post-5 April 2005 service
Rate of increase in deferred pensions

The mortality assumptions are based on standard mortality tables which allow for future mortality improvements. The assumptions 
are such that a member currently aged 65 (2021 aged 65) will live on average for a further 22.0 years (2021 22.2 years) if they are 
male and for a further 24.5 years (2021 24.6 years) if they are female. For a member who retires in 2042 (2021 in 2041) at age 65 
(2021 age 65), the assumptions are that they will live on average for a further 23.6 years (2021 23.8 years) after retirement if they 
are male and for a further 26.2 years (2021 26.3 years) after retirement if they are female. 

iii) Amount, timing and uncertainty of future cash flows 
The approximate impact to past service liabilities of these changes to the main assumptions, which are considered reasonably 
possible, is as follows: 

•  Reducing the discount rate by 0.1 per cent per annum would increase past service liabilities by $2.0 million (2021 $4.3 million). 

The impact is broadly linear.

•  Increasing RPI inflation by 0.1 per cent would increase the plans’ liabilities by $0.7 million (2021 $1.6 million). The impact is broadly linear.

•  Increasing the life expectancy of a member by one year (by modifying the standard mortality tables using an appropriate 

scaling factor) would increase past service liabilities by $8.5 million (2021 $16.4 million).

The accounting valuation of the funded UK defined benefit pension plans as at 31 December 2022 gave rise to a net surplus 
of $13.2 million. Future changes to the valuation assumptions noted above may cause material impacts to the pension liability 
calculations, for example, the discount rate experienced a change of 3.0 per cent between 2021 and 2022.

There will also be an impact on the future service cost but given the small active population in these plans this is likely to be insignificant. 
The sensitivity analysis may not be representative of the actual change as the changes in assumptions may not occur in isolation.

Deferred compensation plan  
At 31 December 2022, the deferred compensation plan deficit amounted to $6.9 million (2021 $6.6 million). 

During the year, $0.3 million was credited to the income statement (2021 $0.2 million charged) and there was no re-measurement 
recognisable directly in the statement of other comprehensive income (2021 a re-measurement loss of $0.2 million). The key 
financial assumptions include a discount rate used to discount plan liabilities of 5.2 per cent (2021 2.6 per cent) and an expected 
investment yield of 9.5 per cent (2021 6.4 per cent). There is no material impact in 2022 or 2021 of changing each of the key 
assumptions by 0.1 per cent, in isolation. 

Defined contribution plans 
United Kingdom 
The Group contributes towards defined contribution pension plans for employees in the United Kingdom. Employer contributions 
into these plans for 2022 were $1.4 million (2021 $1.4 million). 

United States 
The Group maintains a defined contribution pension plan for employees of its United States subsidiaries. This plan, also known as 
a 401(k) Plan, allows employees to defer a percentage of their salary for retirement. In aggregate, the Group’s contributions to the 
US plan totalled $5.2 million for 2022 (2021 $4.7 million). There were no defined benefit plans in the United States in 2022 or 2021. 

Other jurisdictions 
Outside the United Kingdom and the United States, employees are provided with pension arrangements determined in 
accordance with approved local practice and regulations. These arrangements are defined contribution plans. Total employer 
contributions for 2022 in respect of these plans amounted to $1.7 million (2021 $1.7 million). 

Total employer contributions to defined contribution plans were $8.3 million (2021 $7.8 million).

FINANCIAL STATEMENTS10. Tax continued
The current tax charge is impacted by the US R&D capitalisation rules which came into effect in 2022. The impact is an increase 
to our current tax charge with an offsetting deferred tax credit for the future tax benefit of the amortisation deduction. 

The tax charge for the year ended 31 December 2022 was $14.7 million (2021 $14.4 million). This was after a prior year tax charge 
of $1.7 million and a tax credit on adjusting items of $3.9 million (2021 prior year charge of $0.7 million and tax credit on adjusting items 
of $3.3 million). Excluding the prior year charge and tax credit on adjusting items, the effective tax rate was 12.9 per cent (2021 14.4 per cent).

The Group’s tax rate is sensitive to the geographic mix of profits and reflects a combination of higher statutory tax rates in 
certain jurisdictions, and other regions with significantly lower statutory tax rates. Regional statutory tax rates range from a high 
of 35 per cent to a low of 15 per cent. The UK Patent Box deduction benefit of $2.4 million (2021 $2.1 million), US foreign-derived 
intangible income deduction of $3.6 million (2021 $1.6 million), Research and Experimental credits of $2.9 million (2021 $2.4 million) 
and other tax credits of $0.2 million (2021 $0.1 million) realised in Hong Kong bring down the rate but items such as state taxes 
and withholding tax increase the tax rate.

Basic 
Earnings per share is calculated by dividing the profit for the year attributable to owners of the parent Company by the weighted 
average number of Ordinary Shares outstanding during the year.

Diluted
Diluted earnings per share is calculated by dividing the profit for the year attributable to owners of the parent Company by the 
weighted average number of Ordinary Shares outstanding during the year plus the weighted average number of Ordinary Shares 
that would be issued on the conversion of all dilutive potential Ordinary Shares into Ordinary Shares.

The Directors are proposing a final dividend in respect of the financial year ended 31 December 2022 of 4.94 cents per Ordinary 
Share (4.12 pence) (2021 4.37 cents (3.34 pence)), which will absorb an estimated $29.8 million of shareholders’ funds (2021 $25.0 
million). The final dividend will be paid on 10 May 2023 to Ordinary shareholders who are on the Register of Members at close of 
business on 17 March 2023. Payment will be made to ADR holders on 17 May 2023. No liability is recorded in the financial 
statements in respect of these dividends.

Dividends are determined in US Dollars and paid in Pound Sterling. The exchange rate for determining the amount of the final 
dividend to be paid for 2022 was $1.20: £1 (2021 $1.31: £1).

Goodwill is allocated at acquisition to the cash-generating units (CGUs) that are expected to benefit from that business combination.

The Group identifies CGUs at the lowest level at which cash flows are largely independent of other cash flows.

Goodwill has been allocated to two CGUs, which align with the reportable operating segments, as follows:

Annual impairment test
The Group has an annual impairment testing date of 30 November. The key assumptions used in the value in use calculations were:

•  revenue growth rates;

•  gross margin;

•  operating expenses;

•  discount rate; and

•  growth rate used to extrapolate cash flows beyond the five-year period covered by management’s projections.

The cash flows are derived from the most recent financial budgets for the next financial year, as approved by management, and 
the Group’s three-year strategic plan. Cash flows in years four and five are extrapolated based on long range plans. Cash flows 
in subsequent years have been extrapolated using a steady 2.5 per cent for all CGUs (2021 2.5 per cent for all CGUs), which 
management estimates to be the approximate average long-term growth rate for the industries in which these units operate. 
Fundamentally, this long-term growth is based on a proxy for global long-term inflation taking into consideration more 
developed and developing markets. The growth rates used in the value in use calculations are set at the same level for each 
CGU as both CGUs operate within similar markets which share the same growth drivers and characteristics. The discount rates 
incorporate the specific risks relating to each CGU.

Spirent Communications plc Annual Report 2022

153

FINANCIAL STATEMENTS13. Intangible assets continued
Annual impairment test continued
The discount rate applied to the cash flows is based on the weighted average cost of capital of comparable companies by 
taking the risk free rate for 30-year government bonds and making an adjustment to reflect the increased risk of investing in 
equities. In making this adjustment, the inputs required are the equity market risk premium, beta, and the risk adjustment applied 
to reflect the systematic risk of Spirent and the specific CGUs, taking into account factors such as size and the territories in which 
each CGU operates.

The cash flows have been discounted using the following pre-tax discount rates:

Lifecycle Service Assurance
Networks & Security 

2022

12.6

2021

11.3

For Spirent the key factor in relation to the cash flow forecasts is the ability to forecast revenue. All CGUs operate in the data 
technology market and generate a high gross profit (gross margin); consequently changes in revenue can have a significant 
impact on the operating profit and cash flows. Revenue growth rates used in the projections are based on management’s 
estimate of growth in the markets served and take into account historical levels of growth, expected future developments in 
products and technology, industry forecasts and macroeconomic conditions in the territories in which the CGUs operate. Gross 
margin and operating expenses are based on historical values adjusted for the effect of revenue growth, changes in product 
mix, expectations of investment and cost reduction actions committed prior to the impairment testing date.

Management expects revenue growth in the forecast period at Lifecycle Service Assurance from the delivery of a leading active 
assurance platform for 5G and next-generation service assurance, as well as the automation of critical test activities and 
leverage of existing product offerings. The Lumos legacy business is continuing to drop in the near term and is being replaced by 
growth in new Ethernet products supported by investment in product development, particularly in virtualisation, automation and 
5G. Revenue is expected to grow at the Connected Devices business, driven by device lab test 5G expansion, network emulator 
partnerships and managed solutions live network test growth. Management expects gross margin to remain broadly constant 
as increased software content is offset by a growth in services. The individual business units in Lifecycle Service Assurance are 
expected to work together to deliver the three-year plan to meet changes in customer needs and the competitive landscape.

Within Networks & Security, Cloud and IP is expected to maintain its leadership position in high-speed Ethernet, and this together 
with optimised 400G volumes (and introduction of 800G), growth in network virtualisation and emerging technologies, is 
expected to drive earnings. Further growth in Networks & Security is expected at Positioning driven by the emergence of other 
sensors. Management expects that the security business will benefit in the longer term from the move to a subscription-based 
model together with expansion in the cloud-native security market. Cybersecurity is expected to benefit from synergies with 
Positioning and continued expansion in complementary solutions with Cloud and IP.

The recoverable amount of each CGU was calculated on a value in use basis and was in excess of its carrying value. Consequently, 
no impairment has been recognised. 

Sensitivity to changes in key assumptions
The Directors believe that no reasonable possible change in any of the key assumptions used, in isolation, would cause the value 
in use of the Lifecycle Service Assurance or Networks & Security CGUs to fall below the carrying value.

Other intangible assets
There was no impairment charge in respect of the other intangible assets in either 2022 or 2021.

Finance lease receivables (Group as a lessor)
The Group subleases an office building that it leased in 2015. The Group has classified the sublease as a finance lease, because 
the sublease transfers substantially all of the risks and rewards incidental to ownership of the underlying asset to the sub lessee. 

The following table sets out a maturity analysis of lease receivables, showing the undiscounted lease payments to be received 
after the reporting date.

Cash at bank and in hand earns interest at floating interest rates. Of the total cash and cash equivalents balance, $105.8 million 
(2021 $81.1 million) is callable at notice of three months or less at the date of investment.

Short-term bank deposits are made for varying periods of between one day and three months depending on the cash requirements 
of the Group and earn interest at the short-term deposit rates appropriate for the term of the deposit and currency. 

At the end of 2022, the currency split of cash and cash equivalents was US Dollar 83 per cent (2021 80 per cent), Pound Sterling 
7 per cent (2021 9 per cent) and other currencies 10 per cent (2021 11 per cent).

There was no revenue recognised in 2022, 2021 or 2020 from performance obligations satisfied in previous periods.

The timing of revenue recognition, invoicing and cash collections results in trade receivables, deferred income and advance 
customer payments received on account on the balance sheet.

The increase in deferred income in 2021 is due to the year-on-year increase in support contracts which are typically invoiced 
in advance.

The Group receives payments from customers based on a billing schedule, as established in the contract. Trade receivables are 
recognised when the right to consideration becomes unconditional. Contract liabilities are recognised as revenue as (or when) 
the Group performs under the contract. 

The Group also recognises incremental costs incurred to obtain a contract as an asset if it expects to recover those costs. 
Such costs are presented in the balance sheet as assets recognised from costs to obtain a contract and disclosed in note 20.

Expected realisation of remaining performance obligations at year end
The Group applies the practical expedient in paragraph 121 of IFRS 15 and does not disclose information about remaining 
performance obligations that have original expected durations of one year or less.

The above information represents the revenue the Group will recognise when it satisfies the remaining performance obligations 
in the contracts. The amounts presented do not include orders for which neither party has performed.

Revenue from the sale of hardware and software generally arises from contracts less than one year in length. Consequently, 
the above amounts predominantly relate to the sale of maintenance and support services. 

Virtually all of the revenue will be recognised within three years. 

The Group provides standard warranties on its products and services. The nature of these warranties is considered to provide 
customers with assurance that the related product or service will function as intended in accordance with the agreed 
specification, and does not contain or imply any additional service obligation to the customer. Warranty obligations are 
estimated and recognised as liabilities based on the probable outflow of resources.

Extension options 
Some leases of buildings contain extension options exercisable by the Group before the end of the non-cancellable contract 
period. Where practicable, the Group seeks to include extension options in new leases to provide operational flexibility. The 
extension options held are exercisable only by the Group and not the lessors. The Group assesses at lease commencement 
whether it is reasonably certain to exercise the extension options. The Group reassesses whether it is reasonably certain to 
exercise the options if there is a significant event or significant change in circumstances within its control.

FINANCIAL STATEMENTS26. Deferred tax continued
A net deferred tax asset of $32.8 million has been recognised at 31 December 2022 (2021 $10.6 million). $27.6 million is in 
the United States (2021 $15.0 million), $1.7 million is in France (2021 $1.4 million), $2.4 million is in the rest of the world (2021 $2.2 million), 
and $1.1 million is in the United Kingdom (2021 $8.0 million net liability). 

The deferred tax asset includes $3.3 million (2021 $3.3 million) in respect of the tax deduction which may be available on 
the future exercise of share incentives, $5.4 million (2021 $5.8 million) in respect of the future tax deduction on provisions 
and $7.5 million (2021 $7.8 million) in respect of the future tax deduction on the deferral of compensation. These amounts 
are presented within temporary differences. 

The Group has non-trading tax losses arising in the United Kingdom of $27.7 million (2021 $32.0 million), which are available for 
offset against suitable future non-trading taxable profits. Additionally, there are short-term timing differences in the United 
Kingdom of $2.5 million (2021 $2.7 million), and the rest of the world of $7.1 million (2021 $7.6 million), Scientific Research and 
Experimental qualifying expenditure in Canada of $5.2 million (2021 $6.0 million) and tax credits in the rest of the world of $1.4 
million (2021 $1.4 million). A deferred tax asset has not been recognised in respect of these items as their future recovery is not 
probable. The previously unrecognised deferred tax asset of $1.9 million, related to US state tax credits and losses, has now been 
fully recognised as the probability of utilisation of these is likely.

The Group has capital losses carried forward of $996.4 million (2021 $1,109.9 million) for which no deferred tax asset has been 
recognised on the balance sheet. This change is due to foreign exchange movements. These capital losses have no expiry date. 

The temporary difference associated with investments in the Group’s subsidiaries for which a deferred tax liability has not been 
recognised in the periods presented are $251.6 million in aggregate (2021 $239.0 million). The Group does not expect a 
significant amount of the undistributed profits to be distributed in the foreseeable future but has recognised a deferred tax 
liability of $0.4 million (2021 $0.1 million) on the expected distribution of $3.9 million (2021 $2.3 million) of earnings from its 
China subsidiary, $1.6 million (2021 nil) of earnings from its India subsidiary, $0.1 million (2021 nil) from its Taiwan subsidiary 
and $0.2 million (2021 $0.2 million) from its Korea subsidiary. 

Changes in tax rates 
The Group’s future tax charge, and the effective tax rate, could be affected by several factors including tax reform in countries 
around the world and the geographical mix of profits.

Following the enactment of the United Kingdom Finance Bill 2021, the main corporation tax rate is set to increase to 25 per cent 
from 1 April 2023. As such, the United Kingdom temporary differences have been recognised at the rate at which the temporary 
differences are expected to unwind.

The lease provisions are for the continuing obligations under leases in respect of property dilapidation and reinstatement provisions. 
Where material, lease obligations are discounted. The Group expects these provisions to be utilised over one to eight years. 

The restructuring provisions are largely for employee separation costs in relation to the strategic evaluation which commenced 
in 2022 (note 5).

Other provisions comprise environmental provisions related to property disposed of, provisions relating to legal claims and a provision 
relating to a Notice of Recovery received from French Customs, discussed below. The Group expects these provisions to be 
utilised in less than one year. 

In 2018, the Group made a provision for $8.9 million following the receipt of a Notice of Recovery from the Direction Générale 
des Douanes et Droits Indirects (French Customs) in relation to the valuation and classification of duty on certain imports into 
France. This dispute commenced with enquiries in 2011. During the period in question, Spirent adopted a duty tariff based on 
World Customs Organization guidelines which conflicted with European Union regulation. In 2019, the Group paid $6.5 million 
in relation to this claim, of which $2.3 million was later recovered. The import regulations changed on 1 January 2017 and no 
liability exists after that date. Spirent has provided for the liability up until the date of the change, which encompasses the period 
covered by the Notice of Recovery. 

28. Financial instruments and financial risk management 
The main purpose of the Group’s financial instruments, other than trade and receivables, trade and other payables, contractual 
provisions and lease liabilities, is to fund the Group’s liquidity requirements.

The Group enters into derivative transactions, forward foreign currency exchange contracts, for the management of the Group’s 
foreign currency exposures when deemed appropriate. 

The key objective of the Group’s treasury department is to manage the financial risks of the business and to ensure that sufficient 
liquidity is available to the Group. All treasury activity operates within a formal control framework. The Board has approved 
treasury policies and guidelines and periodically reviews treasury activities. Additionally, it is the Group’s policy that speculative 
treasury transactions are expressly forbidden.

FINANCIAL STATEMENTS28. Financial instruments and financial risk management continued
a) Market risk 
The main types of market risk that affect the Group are interest rate risk and exchange rate risk. 

Interest rate risk 
The Group has external debt in relation to its lease liabilities (note 25) but has limited exposure to interest rate risk as the 
incremental borrowing rate used to discount these lease liabilities is fixed at the lease commencement date. The Group’s excess 
funds are principally held in the United Kingdom and the United States and invested in on-demand or short-term bank deposits. 
It therefore has some exposure to interest rate risk arising on changes in Pound Sterling and US Dollar interest rates. 

Cash and cash equivalents and forward foreign currency exchange contracts are the Group’s financial instruments which are 
exposed to interest rate risk. 

Short-term bank deposits and forward foreign currency exchange contracts mature within three months. The financial 
instruments bear the following interest rates:

81.1

Interest rates on financial instruments classified as fixed rate are fixed until the maturity of the instrument. All fixed rate deposits 
mature within three months after which date they will be exposed to floating rates of interest. 

Interest receivable for the year (note 6) was $2.1 million (2021 $0.3 million) and is under the effective interest method.

The other financial instruments of the Group that are not included in the above table are non-interest bearing and are therefore 
not subject to interest rate risk. 

A movement of 25 basis points in interest rates based on levels of investment at 31 December 2022 would increase or reduce 
interest income and equity by $0.4 million (2021 $0.3 million).

Exchange rate risk 
Currency exposures arise from trading transactions undertaken by the Group in foreign currencies and on the translation of the 
operating results and net assets of overseas subsidiaries. 

The Group has the majority of its operations in the United States and presents its consolidated financial statements in US Dollars. 
The parent Company’s functional currency is Pound Sterling and its share capital is denominated in Pound Sterling; the Group 
also has operations in Europe and Asia and therefore its results and assets and liabilities are affected on translation by movements 
in exchange rates in relation to the US Dollar. The Group does not enter into instruments to hedge the translation exposure of the 
operating results or net assets of its overseas subsidiaries since these are considered accounting and not cash exposures. 

The Group undertakes transactions denominated in foreign currencies; consequently exposures to exchange rate fluctuations arise. 
Exchange rate exposures are managed within approved policy parameters using forward foreign currency exchange contracts. 

The main exposures arise in relation to the retranslation of foreign operations to US Dollar, on non-local currency denominated 
transactions and on non-local currency denominated cash balances. These exposures predominantly arise on Sterling, Euro and 
Chinese Yuan transactions and balances. A 10 per cent appreciation or depreciation of these currencies against the US Dollar 
would decrease or increase profit before tax based on the activity in the period and balances at the reporting date as follows: 
Sterling $0.6 million, Euro $0.1 million and Chinese Yuan $1.0 million (2021 Sterling $6.7 million, Euro $0.1 million and Chinese Yuan 
$2.7 million). A 10 per cent currency fluctuation represents management’s assessment of the reasonably possible change in 
foreign exchange rates.

b) Credit risk 
Investment counterparties are subject to pre-approval by the Board with pre-approved limits set for each bank to avoid 
any concentrations of credit risk. 

The maximum credit exposure at the balance sheet date under financial instruments in relation to cash and bank deposits 
is equal to the carrying value of $209.6 million (2021 $174.8 million).

Trade receivables, which generally have 30 to 90-day terms, are carried at original invoice amount less an allowance for 
expected credit losses. Trade receivable exposures are managed in the business units where they arise. 

164

Spirent Communications plc Annual Report 2022

FINANCIAL STATEMENTSNotes to the consolidated financial statements continued28. Financial instruments and financial risk management continued
b) Credit risk continued
The Group applies the IFRS 9 simplified approach to measuring expected credit losses which uses a lifetime expected loss 
allowance for all trade receivables. Therefore, the Group does not track changes in credit risk, but instead recognises a loss 
allowance based on lifetime expected credit loss at each reporting date. To measure the expected credit losses, the Group has 
established a provision matrix that is based on shared credit risk characteristics and the days past due based on the expected 
loss rates. 

The provision matrix is initially based on payment profiles of trade receivables over a period of 12 months before 31 December 2021 
and the corresponding historical credit losses experienced within this period. At every reporting date the historical observed default 
rates are updated. The Group also considers the impact of regional macroeconomic factors on the likelihood of future losses. 

The Group has no significant concentration of credit risk attributable to its trade receivables as the exposure is spread over a 
large number of customers with no one customer accounting for more than 9 per cent of total Group revenue. The maximum 
credit exposure at the balance sheet date in relation to trade receivables is equal to the carrying value of $142.4 million (2021 
$149.2 million). 

The composition of trade receivables at 31 December is as follows: 

Neither impaired nor past due
Past due but not impaired: 
– Less than 30 days overdue
– 30 to 60 days
– Over 60 days

Trade receivables

The Group closely monitors amounts due from customers and performs activities such as credit checks and reviews of payment 
history and has put in place appropriate credit approval limits. Based on these procedures, management assessed the quality 
of those receivables that are past due but not impaired as low risk. 

The receivables’ provision is based on expected credit losses. The movement on the provision during the year is given in note 19. 
The value of impaired trade receivables is $1.4 million (2021 $0.7 million). For all other financial assets, the maximum exposure 
to credit risk is represented by the carrying amount.

c) Liquidity risk 
The Group’s objective is to ensure that there are sufficient sources of funding to meet projected requirements. Its operations 
are financed through cash and cash equivalents held centrally and cash generated from operations. 

At 31 December 2022, the Group had cash and cash equivalents of $209.6 million (2021 $174.8 million), of which $103.8 million 
(2021 $93.7 million) is available on demand and $105.8 million matures within three months (2021 $81.1 million matures within 
three months).

During 2022, the Group generated $117.8 million of cash from operating activities (2021 $102.9 million) and considers that, with 
current cash resources, debt only in relation to its lease liabilities and positive cash flow from its operating activities, it has 
adequate resources available to it to remain in operational existence for the foreseeable future.

The Group has entered into forward foreign currency exchange contracts at 31 December, all of which mature within three months. 
The gross settlement amounts of these contracts are as follows: 

Sale of US Dollars against Pound Sterling

2022
$ million

2021
$ million

5.5

The Group has external debt in relation to its lease liabilities (note 25) but is otherwise debt free and does not have loans 
payable. Financial liabilities are trade and other payables, the majority of which are due to be settled within one year, and 
contractual provisions (note 27). 

The Group does not have any other material financial contractual commitments. 

Spirent Communications plc Annual Report 2022

FINANCIAL STATEMENTS28. Financial instruments and financial risk management continued
d) Fair value of financial instruments 
The carrying value of all financial assets and liabilities is a reasonable approximation of fair value. 

Derivative financial instruments are stated at fair value although the amounts at 31 December 2022 and 2021 were immaterial. 

Corporate owned life insurance is stated at fair value and is at Level 1 in the fair value hierarchy as the valuation of the linked 
investments is based on quoted prices in active markets. 

e) Capital management 
The primary objective of the Group’s capital management is to support its business and maximise shareholder value. The Group’s 
capital is its total shareholders’ funds. 

The Group manages its capital structure and intends to maintain a cash positive balance sheet over the medium to long term. This should 
allow the Group to maintain a strong capital position in the face of business risks, trading fluctuations and working capital demands. 

Spirent’s policy on the payment of dividends to shareholders is to maintain a progressive dividend policy. To the extent the Group 
has excess cash, it will consider returning such cash to shareholders.

b) Equity and reserves 
The nature and purpose of each reserve within equity is as follows: 

•  Share premium account: this reserve records the consideration premium for shares issued at a value that exceeds their 

nominal value. 

•  Capital redemption reserve: this reserve arises in relation to share capital cancellation. 

•  Other reserves: share capital, share premium account and capital redemption reserve are translated into US Dollars at 
the rates of exchange at the balance sheet date and the resulting exchange differences are included in other reserves. 

•  Translation reserve: this reserve is used to record exchange differences arising from the translation of the financial statements 

of foreign subsidiaries. 

Investment in own Ordinary Shares 
During the year, 7.1 million shares were purchased and placed into the Employee Share Ownership Trust at a cost of $22.9 million, 
and 2.7 million shares were transferred from the Employee Share Ownership Trust to satisfy options exercised under the Spirent 
employee share plans (2021 3.9 million shares purchased and placed at cost of $15.1 million, and 2.3 million shares transferred). 

At 31 December 2022, the Employee Share Ownership Trust held 8.9 million Ordinary Shares (2021 4.5 million Ordinary Shares) 
to satisfy awards under various share incentive plans. At 31 December 2022, the Spirent Sharesave Trust held 0.5 million Ordinary 
Shares (2021 0.5 million Ordinary Shares) to satisfy awards made to United Kingdom based employees under an all-employee 
share scheme. The market value of own Ordinary Shares held in trust, being in total 9.4 million Ordinary Shares (2021 5.0 million 
Ordinary Shares), at 31 December 2022 was $29.6 million (2021 $18.6 million).

Both the Employee Share Ownership Trust and the Spirent Sharesave Trust are an extension of the parent Company.

Spirent Long-Term 
Incentive Plan

Discretionary plans 
Spirent Long-Term Incentive Plan (LTIP) 
Under the LTIP, awards of shares are granted to Executive Directors and certain employees. The release of these shares is 
conditional upon continued employment and for some awards achievement of certain performance targets measured over 
a three-year period.

Further information on the performance conditions for LTIP share incentives is set out in the Report on Directors’ Remuneration.

2005 Employee Incentive Plan (EIP) 
The EIP closed for new awards following the 2016 AGM and was replaced by the Spirent Long-Term Incentive Plan. Awards 
granted under the EIP expire on the tenth anniversary of their grant unless they have previously lapsed or been exercised.

FINANCIAL STATEMENTS30. Employee share plans continued
All-employee plans 
UK Employee Share Purchase Plan (UK ESPP) 
The UK ESPP is an all-employee HMRC approved share plan open to employees based in the UK. Employees can elect to invest 
up to £125 each month (£1,500 per year), deducted from their gross salary, which is used to purchase shares at market value as 
“partnership” shares. The Company offers participants “matching” shares, which are subject to forfeiture for three years, on the 
basis of one free matching share for each partnership share purchased.

UK Sharesave Plan (Sharesave)
The Sharesave is an all-employee HMRC approved share plan open to employees based in the UK. Employees can elect to 
invest up to £250 each month, deducted from their post-tax salary, which is then held in a savings account for three years. At the 
conclusion of the savings period, the employee can opt to receive the accumulated funds as cash or use them to buy Spirent 
shares at a discounted option price that is 15 per cent below the three-day average of Spirent’s mid-market share price 
immediately before the invitation date. The first Sharesave invitation was made to UK employees in August 2022.

US Employee Stock Purchase Plan (US ESPP) 
The US ESPP is available to all employees based in the US. Employees can elect to save up to $8,000 per year, deducted from 
their post-tax salary, for a 12-month period. The savings are then used to purchase shares at an effective 15 per cent discount 
to the prevailing market share price at the end of the savings period (the discount being funded by the Company).

Global All-Employee Share Purchase Plan (GAESPP) 
The GAESPP is available to employees in countries other than the UK and US, on a share-settled or cash-settled basis, depending on 
local regulations. Employees can elect to save funds, deducted from their post-tax salary, for a 12-month period. In the share-settled 
model, these savings are then used to purchase shares at an effective 15 per cent discount to the prevailing market share price at the 
end of the savings period (the discount being funded by the Company); in the cash-settled model, these savings are then returned to 
the participant, along with an additional cash enhancement equal to a 15 per cent discount to the prevailing market share price at the 
end of the savings period, had the funds been used to purchase Spirent shares (the enhancement being funded by the Company).

Employees participating in the GAESPP during the period under review included those based in Canada, France, Germany, 
China, Hong Kong, India, Spain, Japan and South Korea.

Notes
1.  2022 includes $0.3 million (2021 $0.3 million) relating to cash-settled schemes. 
2.  2022 includes $0.1 million (2021 nil) relating to cash-settled schemes. 
All schemes are primarily equity-settled with elements cash settled pursuant to local legislation.

In 2022, $0.4 million (2021 $0.6 million) being one-third of the Executive Directors’ Annual Incentive has been deferred into shares 
for an additional period of three years. This amount has been charged to administration expenses in the income statement and 
is included within adjusted operating profit as it reflects part of the underlying trading performance of the Group.

4 million share incentives were granted during 2022 (2021 2.7 million). The fair value of share incentives has been estimated as 
at the date of grant using the Black-Scholes binomial model. The following table gives the assumptions made in arriving at the

The expected volatility was determined by calculating the historical volatility of the Company’s share price over the previous two 
years which management considers to be the period which is likely to be most representative of future volatility. The risk free rate 
is calculated by reference to UK government bonds.

33. Business combinations 
There were no business combinations in 2022. 

On 4 March 2021, Spirent acquired 100 per cent of the issued share capital of octoScope, Inc (octoScope), a company based 
in the United States for an initial cash consideration of $57.9 million. Additionally, there are acquisition related performance 
payments of up to $17.8 million, payable based on revenue growth targets for 2021 and 2022 and/or retention of key staff. 
The transaction was funded by surplus cash in the Group.

octoScope provides market-leading accurate, repeatable and automated wireless test solutions and methodologies to the 
wireless industry. Its test solutions leverage patented technology to provide automated Wi-Fi and 5G testing in emulated 
real-world environments, including the Wi-Fi 6 and 6E technologies. The acquisition has enabled the Group to consolidate its 
leadership in Wi-Fi test. octoScope has been incorporated into our Lifecycle Service Assurance operating segment.

Of the acquisition related performance payments, amounts of up to $16.2 million are linked to post-acquisition service and 
therefore will be charged to the income statement in the relevant post-acquisition period, and amounts up to $1.6 million, which 
are not linked to post-acquisition service and only to revenue growth targets, have been included as contingent consideration on 
acquisition and a liability recorded. The remaining acquisition related performance payments are retention bonuses. 

In 2022, $0.1 million (2021 $0.6 million) of acquisition related performance payments have been credited (2021 charged) to other 
adjusting items in the income statement (note 5). On acquisition date, the fair value of the contingent consideration was estimated 
at $0.7 million and a liability recorded for this amount. During the year, the liability was remeasured down by $0.5 million (2021 
$0.3 million), through other adjusting items in the income statement (note 5). During 2021, there was also $0.1 million incurred in 
relation to the unwind of discounting. At 31 December 2022, the liability had a fair value of nil (31 December 2021 $0.5 million).

The fair value adjustments arose in relation to the recognition of acquired intangible assets net of the associated deferred 
tax liability, and on the recognition of a receivable in relation to an indemnification asset in respect of a loan that existed 
on acquisition date. The trade and other receivables acquired were mainly trade receivables due from customers and the 
book value on acquisition date approximated the fair value. All of the receivables acquired were expected to be collected. 

The intangible assets acquired represent current technology, customer relationships and brand. These intangible assets have 
been assigned a useful life of between three and six years.

The goodwill arising of $26.6 million consists largely of the synergies and economies of scale expected from the combination 
together with intangible assets not qualifying for separate recognition, such as workforce in place. The goodwill recognised is 
not expected to be deductible for income tax purposes.

Direct acquisition related costs of $0.6 million (2021 $1.9 million) have been expensed to other adjusting items within the income 
statement in 2022 (note 5). 

From the date of acquisition to 31 December 2021, octoScope contributed $18.2 million of revenue and $5.2 million of profit before 
tax to the results of the Group before charging $1.9 million of direct acquisition related costs and $3.8 million of acquired intangible 
asset amortisation. If the combination had occurred at the beginning of the financial year, revenue of $20.2 million and a profit 
before tax of $3.9 million would have been included in the Group result before charging $1.9 million of direct acquisition related 
costs and $4.6 million of acquired intangible asset amortisation.

FINANCIAL STATEMENTS 
 
Notes to the parent Company financial statements

1. Significant accounting policies
Corporate information
Spirent Communications plc (the “Company”) is a public limited company incorporated and domiciled in England and Wales 
(registration number 470893). The registered address of the Company is Origin One, 108 High Street, Crawley, West Sussex 
RH10 1BD, United Kingdom.

Basis of accounting
The financial statements have been prepared in accordance with United Kingdom Generally Accepted Accounting Practice 
(United Kingdom Accounting Standards and applicable law), including Financial Reporting Standard 101 ‘Reduced Disclosure 
Framework’ (FRS 101) and the Companies Act 2006.

In preparing these financial statements, the Company has set out below the FRS 101 disclosure exemptions that have been taken 
in respect of the following disclosures:

•  a cash flow statement and related notes;

•  comparative period reconciliations for share capital, tangible assets and intangible assets;

•  disclosures in respect of transactions with wholly owned subsidiaries;

•  disclosures in respect of capital management;

•  the effects of new but not yet effective IFRS; and

•  disclosures in respect of the compensation of key management personnel.

As the consolidated financial statements include the equivalent disclosures, the Company has also taken the exemptions under 
FRS 101 available in respect of the following disclosures:

•  IFRS 2 “Share-based Payment” in respect of Group-settled share-based payments;

•  certain disclosures required by IAS 36 “Impairment of Assets” in respect of the impairment of goodwill and indefinite life 

intangible assets; and

•  the disclosures required by IFRS 7 “Financial Instruments Disclosures” and IFRS 13 “Fair Value Measurement” regarding 

financial instrument disclosures have not been provided apart from those which are relevant for the financial instruments 
which are held at fair value.

As the Company is included in the consolidated financial statements, made up to 31 December each year, it is not required to 
present a separate profit and loss account as provided by Section 408 of the Companies Act 2006. Information on fees for 
non-audit services in respect of the parent Company accounts have not been disclosed as the Company prepares Group 
accounts which disclose information on fees for non-audit services on a consolidated basis.

Accounting convention
The financial statements are prepared on a historical cost basis apart from certain financial instruments that have been measured 
at fair value, and the defined benefit pension asset/liability which has been measured using the projected unit credit method.

Going concern basis of accounting
In adopting the going concern basis for preparing the financial statements, the Directors have considered the Company’s principal 
risks and uncertainties as set out on pages 55 to 60.

The Directors have also considered sensitivities in respect of potential downside scenarios, including stress testing the latest cash 
flow projections that cover a period of 12 months from the date of approval of these financial statements. In these scenarios, the 
Company has more than sufficient headroom in its available resources.

The Directors have reviewed the detailed financial projections for the period ending 31 December 2023, as well as the business 
plan and cash flows for the three months ending 31 March 2024. The Directors have also considered the period to the end of 
2025 which forms part of the Company’s longer-term viability assessment. In addition, they have considered the principal risks 
faced by the Company, the sensitivity analysis and the Company’s significant financial headroom and are satisfied that the 
Company has adequate financial resources to continue in operational existence for the foreseeable future, a period of at least 12 
months from the date of approval of this report. Accordingly, the going concern basis of accounting continues to be used in the 
preparation of the financial statements.

New accounting standards
There have been no applicable new standards, amendments to standards and interpretations effective from 1 January 2022 
that have been applied by the Company which have resulted in a significant impact on its results or financial position.

FINANCIAL STATEMENTS1. Significant accounting policies continued
Business combinations and goodwill
A business combination is a transaction or other event in which an acquirer obtains control of one or more businesses. Business 
combinations are accounted for using the acquisition method.

At acquisition date, the identifiable assets acquired and liabilities assumed, including intangible assets, are measured at their 
fair values. The cost of an acquisition is measured as the aggregate of the consideration transferred and the amount of any 
non-controlling interest in the acquiree.

Goodwill arising on the acquisition of a business, representing the excess of cost over the net fair value of the net assets acquired, 
is capitalised as an intangible asset. Goodwill is carried at cost less any accumulated impairment losses.

For the purpose of impairment testing, goodwill is allocated to the related cash-generating units monitored by management. 
Where the recoverable amount of the cash-generating unit is less than its carrying amount, including goodwill, an impairment 
loss is recognised in the profit and loss account.

The UK Companies Act requires goodwill to be reduced by provisions for amortisation on a systematic basis over a period 
chosen by the Directors, its useful economic life. However, under IFRS 3 “Business Combinations” goodwill is not amortised. 
Consequently the Company does not amortise goodwill, but reviews it for impairment on an annual basis or whenever there 
are indicators of impairment. The Company is therefore invoking a ‘true and fair view override’ to overcome the prohibition 
on the non-amortisation of goodwill in the Companies Act. 

Had the Company amortised goodwill a period of 20 years would have been chosen as the useful life for goodwill. There would 
have been an impact of £0.1 million (2021 no impact) to profit in the year had goodwill been amortised.

Intangible assets
Intangible assets are carried at cost less accumulated amortisation and accumulated impairment losses. Separately identifiable 
intangible assets such as current technology are capitalised on the balance sheet only when the value can be measured reliably, 
or the intangible asset is purchased as part of the acquisition of a business. Such intangible assets are amortised over their 
useful economic lives on a straight-line basis. The carrying value of intangible assets is reviewed for impairment if events or 
changes in circumstances indicate the carrying value may not be recoverable. Acquired intangible assets, being current 
technology, are amortised on a straight-line basis over their estimated useful lives and the charge is included within the 
profit and loss account. 

The estimated useful life of the current technology intangible asset is five years and the expiry date is 2024.

Product development
Research expenditure is recorded as a product development cost in the year in which it is incurred. Intangible assets arising on 
the Company’s various product development projects are recognised only if the recognition criteria of IAS 38 “Intangible Assets” 
are met.

Product development costs are expensed as incurred until the technological feasibility of the product under development has 
been established. Technological feasibility in Spirent’s circumstances occurs when a working model is completed. For software 
development, technological feasibility is not established until the process of developing the software is complete. After technological 
feasibility is established, additional costs are capitalised and amortised on a straight-line basis over the estimated useful life.

At 31 December 2022 and 31 December 2021, no amounts have met the recognition criteria.

Tangible assets
Tangible assets are stated at cost less accumulated depreciation and accumulated impairment. Depreciation is not provided on 
freehold land. Depreciation is provided to write-off the cost less estimated residual value of all other assets, over their estimated 
useful lives, on a straight-line basis at rates which take into account commercial conditions at their location. Usual asset lives are 
as follows:

Freehold buildings
Plant and machinery
Fixtures, fittings and equipment:
– Building installations
– Fittings and equipment
– Motor vehicles
– Business systems software

50 years
3 to 8 years

20 years or lease period if lower
3 to 8 years
3 to 5 years
4 years

Business systems software is capitalised as tangible assets as the software is an integral part of the related hardware. 

The carrying values of tangible assets are reviewed for impairment if events or changes in circumstances indicate that 
the carrying value may not be recoverable.

Spirent Communications plc Annual Report 2022

FINANCIAL STATEMENTS1. Significant accounting policies continued
Impairment of assets
Intangible assets with finite useful lives and tangible assets and right-of-use assets are tested for impairment at each reporting date 
where there is an indication that an asset may be impaired. Goodwill with an indefinite useful life is assessed at least annually. When 
an impairment test is performed, the recoverable amount is assessed by reference to the higher of the net present value of the 
expected cash flows (value in use) of the relevant cash-generating unit or asset and the fair value less cost of disposal. In assessing 
value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current 
market assessments of the time value of money and the risks specific to the asset. Where the carrying amount of an asset exceeds its 
recoverable amount, the asset is considered impaired and is written down to its recoverable amount. Impairment losses are 
recognised in the profit and loss account in those expense categories consistent with the function of the impaired asset.

Where an impairment loss has been recognised against an asset, it may be reversed in future periods where there has been a 
change in the estimates used to determine the asset’s recoverable amount since the last impairment loss was recognised, but 
only to the extent that the asset’s carrying amount does not exceed the carrying amount that would have been determined, net 
of depreciation or amortisation, had no impairment loss been recognised in prior years. Such a reversal is recognised in the 
profit and loss account. This does not apply for goodwill, for which an impairment loss must not be reversed in any circumstances.

Investments
Investments in subsidiaries are stated at cost and reviewed for impairment if there are indications that the carrying value may 
not be recoverable.

Leases
The Company assesses whether a contract is or contains a lease, at inception of a contract. A contract is, or contains, a lease 
if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. 

The Company recognises a right-of-use asset and a corresponding lease liability with respect to all lease agreements in which it 
is the lessee at the commencement date of the lease (i.e. the date the underlying asset is available for use), except for short-term 
leases (defined as leases with a lease term of 12 months or less) and leases of low-value assets. For these leases, the Company 
recognises the lease payments within the profit and loss account on a straight-line basis over the period of the lease.

At the commencement date of the lease, the lease liability is initially measured at the present value of lease payments to be 
made over the lease term, discounted using the rate implicit in the lease. If this rate cannot be readily determined, the Company 
uses its incremental borrowing rate. Under the modified retrospective transition method, which is the method the Company 
adopted on transition to IFRS 16 “Leases” on 1 January 2019, lease liabilities are required to be discounted using the incremental 
borrowing rate at date of transition. The Company has set the discount rate based upon the local base rate with an additional 
premium to reflect various factors such as credit risk.

The lease payments include fixed payments (including in-substance fixed payments) less any lease incentives receivable, 
variable lease payments that depend on an index or rate, and amounts expected to be paid under residual value guarantees. 
The lease payments also include the exercise price of a purchase option reasonably certain to be exercised by the Company 
and payments of penalties for terminating a lease, if the lease term reflects the Company exercising the option to terminate. 
The variable lease payments that do not depend on an index or a rate are recognised as an expense in the period on which 
the event or condition that triggers the payment occurs.

The lease liability is presented within creditors in the balance sheet.

The lease liability is subsequently measured by increasing the carrying amount to reflect interest on the lease liability (using the 
effective interest method), and by reducing the carrying amount to reflect the lease payments made. It is re-measured when 
there is a change in future lease payments arising from a change in an index or rate, or if the Company changes its assessment 
of whether it will exercise a purchase, extension or termination option.

When the lease liability is re-measured in this way, a corresponding adjustment is made to the carrying amount of the right-of-use 
asset, or is recorded in profit or loss if the carrying amount of the right-of-use asset has been reduced to zero. 

The right-of-use asset is initially measured at cost, which comprises the initial amount of the corresponding lease liability, adjusted for any 
lease payments made at or before the commencement date, plus any initial direct costs incurred and an estimate of costs to dismantle 
and remove the underlying asset or to restore the underlying asset or the site on which it is located, less any lease incentives received. 

The right-of-use asset is subsequently depreciated using the straight-line method from the commencement date to the earlier 
of the end of the useful life of the right-of-use asset or the end of the lease term. In addition, the right-of-use asset is periodically 
reduced by impairment losses, if any, and adjusted for certain remeasurements of the lease liability.

The right-of-use assets are presented as a separate line in the balance sheet. 

Stocks
Stocks are valued at the lower of cost and estimated net realisable value, after provisions for obsolescence. Cost includes all 
costs in bringing each product to its present location and condition, being the full manufacturing cost on a first-in, first-out basis, 
including all attributable overheads based on a normal level of activity.

Provisions
Provisions are recorded when the Company has a present legal or constructive obligation as a result of a past event, for which 
it is probable that it will be required to settle by an outflow of resources and for which a reliable estimate of the amount of the 
obligation can be made. Provisions are reviewed at each balance sheet date and adjusted to reflect the current best estimate.

Where the effect of the time value of money is material, the amount of the provision shall be the present value of the 
expenditures expected to be required to settle the obligation.

Foreign currencies
The financial statements are presented in Pound Sterling, which is the Company’s functional and presentation currency. 

Transactions in foreign currencies are initially recorded at the rates ruling at the date of the transaction. Monetary assets and 
liabilities denominated in foreign currencies are retranslated at the rates ruling at the balance sheet date. All exchange gains 
and losses are taken to the profit and loss account.

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

Trade debtors
Trade debtors are non-interest bearing and are stated at original invoiced amount less an appropriate allowance for expected credit 
losses. At each reporting date, the Company measures the loss allowance at an amount equal to the lifetime expected credit losses. 

The Company applies the IFRS 9 simplified approach to measuring expected credit losses which uses a lifetime expected loss 
allowance for all trade debtors. Therefore, the Company does not track changes in credit risk, but instead recognises a loss allowance 
based on lifetime expected credit losses at each reporting date. To measure the expected credit losses, the Company has established 
a provision matrix that is based on shared credit risk characteristics and the days past due based on the expected loss rates.

The provision matrix is initially based on payment profiles of trade debtors over a period of 12 months before 31 December of 
the prior year and the corresponding historical credit losses experienced within this period. At every reporting date the historical 
observed default rates are updated. The Company also considers the impact of regional macroeconomic factors on the 
likelihood of future losses.

Trade debtors are written off when there is no reasonable expectation of recovery.

A default on a trade debtor occurs when the debtor fails to make contractual payments when they fall due. 

Cash at bank and in hand
Cash at bank and in hand in the balance sheet comprise cash at bank and in hand and short-term deposits which have 
an original maturity of three months or less. There are no bank overdrafts.

Trade creditors
Trade creditors are non-interest bearing and are stated at the original invoiced amount.

Loans and borrowings
Loans and borrowings are recognised initially at fair value less attributable transaction costs. Subsequent to initial recognition, loans and 
borrowings are stated at amortised cost using the effective interest method, and in respect of financial assets, less any impairment losses.

Impairment losses are based on lifetime expected credit losses.

Equity instruments
Equity instruments are recorded at the proceeds received, net of direct issue costs. Spirent Communications plc Ordinary Shares 
held by the Company are classified in equity as treasury shares and are recognised at cost and included as a deduction from 
the profit and loss account reserve. Consideration received for the sale of such treasury shares is also recognised in equity.

Derivative financial instruments
The Company uses forward foreign currency exchange contracts to manage exposures arising on receipts and payments in 
foreign currencies relating to firm commitments.

Forward foreign currency exchange contracts are initially recognised at fair value on the date on which the contract is entered 
into, and are subsequently re-measured to fair value at each reported balance sheet date. The fair value of forward foreign 
currency exchange contracts is calculated by reference to current forward exchange rates for contracts with similar maturity 
profiles. The Company has not adopted the hedge accounting rules. Consequently all gains and losses arising from changes 
in fair value are taken to the profit and loss account.

FINANCIAL STATEMENTS1. Significant accounting policies continued
Pensions
The Company operates two funded defined benefit pension plans. All other pension plans are defined contribution in nature 
where the amount charged to the profit and loss account is the employer’s contributions paid or payable during the year.

For defined benefit pension plans, full actuarial valuations are carried out every three years using the projected unit credit method, 
and updates are performed at each balance sheet date. Re-measurement, comprising actuarial gains and losses, the effect of 
changes to the asset ceiling (if relevant) and the return on plan assets (excluding interest), is reflected immediately in the balance sheet 
surplus with a charge or credit recognised in other comprehensive income in the period in which they occur. Re-measurement 
recognised in other comprehensive income will not be reclassified to profit or loss. Past service cost is recognised in profit or loss in the 
period of plan amendment. Net interest is calculated by applying the discount rate at the beginning of the period to the net defined 
benefit pension asset, taking account of any changes in the net defined benefit pension asset during the period as a result of 
contribution and benefit payments. Where a refund of a surplus is expected, any applicable taxes that are not income in nature are 
netted off. Defined benefit pension costs are categorised as:

•  service cost (including current service cost, past service cost and gains and losses on curtailments or settlements);

•  net interest expense or income; and

•  re-measurement.

The Company presents the first two components of defined benefit pension costs in profit or loss.

Revenue
Revenue represents the transfer of promised products or services to customers in an amount that reflects the consideration 
to which the Company expects to be entitled in exchange for those products or services.

Revenue from product sales of hardware and perpetual software licences is recognised at the point in time when the customer 
has obtained control of the products sold. This is usually when the products have been delivered in accordance with the 
contractual terms. In some instances it is not until acceptance has occurred that control of the asset is transferred to the 
customer. Terms of acceptance are dependent upon the specific contractual arrangement agreed with the customer. If it can be 
objectively determined that control has been transferred to the customer in accordance with the agreed contract specifications, 
customer acceptance is a formality that would not affect the determination of when the customer has obtained control of the 
products. However, if it cannot be objectively determined that the products delivered are in accordance with the agreed-upon 
contract specifications, revenue would not be recognised until customer acceptance has been granted. 

For sales of software licences, the Company determines whether the licence is capable of being distinct and is separately 
identifiable from other promises in the context of the contract. Revenue from software subscription licences that provide the 
customer with a right to access the Company’s intellectual property throughout the subscription period is recognised over time, 
throughout the subscription period. Revenue from perpetual software licences that provide the customer with a right to use the 
Company’s intellectual property for an indefinite period of time is recognised at the point in time when the customer can first use 
and benefit from the software.

For the sale of services, revenue is generally recognised over time with reference to when or as the performance obligations 
are satisfied by transferring the service to the customer. Revenue from support and maintenance service contracts and software 
subscription sales is recognised over the period of performance on a straight-line basis. 

Revenue from professional services is generally recognised as work progresses in accordance with agreed-upon contractual terms, 
based on a measure of progress towards complete satisfaction of the performance obligation. Progress is measured using either an 
output method (e.g. completion of a day, or for fixed price contracts revenue is recognised based on performance completed or 
contractual milestones reached) or an input method (e.g. actual cost of services provided as a proportion of total cost of services 
expected to be provided under the contract). Where applicable, the Company elects to use the practical expedient where revenue 
can be recognised in the amount to which the Company has a right to invoice, only if the Company has a right to consideration from 
a customer in an amount that corresponds directly with the value to the customer of the Company’s performance completed to date. 
Where the Company’s professional services contracts contain terms of acceptance, revenue would not be recognised until customer 
acceptance had been obtained. Where the professional service has a pre-determined or fixed output deliverable, revenue is recognised 
at a point in time once the performance obligation has been satisfied and the customer has received the agreed deliverable.

The Company accounts for multi-component orders as multiple performance obligations if the following criteria are met:

a) 

b) 

 the good or service is capable of being distinct, that is, they are individually readily available and regularly sold separately 
to customers; and

 the promise to transfer the good or service is distinct in the context of the contract, that is, they do not require significant 
integration, customisation or modification with other goods or services in the contract and are not highly interrelated or 
interdependent of other goods or services in the contract.

For multi-component orders where the elements are accounted for as multiple performance obligations, the transaction price 
and discount, if any, are allocated proportionally to all performance obligations in the contract. If either of the two criteria above 
are not met, and where various components in the contract are combined, bundled or pre-assembled into one or more product 
or equipment units to form a distinct good or service, they will be accounted for as a single performance obligation.

Cost of sales
The Company’s cost of sales related to the sale of its products includes materials, payments to third party contract manufacturers, 
royalties and salaries and other expenses related to its manufacturing and supply operations personnel. Cost of sales related to 
the provision of services includes salaries and other expenses associated with technical support services and the cost of 
extended maintenance services.

Costs to obtain a contract
The incremental costs of obtaining a contract with a customer are capitalised as an asset if the Company expects to recover 
them. The Company incurs costs such as sales commissions when it enters into a new contract. Such costs are presented within 
debtors in the balance sheet as assets recognised from costs to obtain a contract where the related revenue is recognised over 
time, usually in relation to support and subscription agreements. These assets are amortised on a systematic basis consistent 
with how the related revenue is recognised. 

The Company applies the practical expedient in paragraph 94 of IFRS 15 and recognises incremental costs of obtaining a 
contract as an expense when incurred if the amortisation period of the asset that the Company would otherwise have 
recognised is one year or less. 

Management is required to determine the recoverability of assets recognised from costs to obtain a contract. At each reporting 
date, the Company determines whether or not the assets are impaired by comparing the carrying amount of the asset to the 
remaining amount of consideration that the Company expects to receive less the costs that relate to providing services under the 
relevant contract. No assets were impaired as at 31 December 2022 or 31 December 2021.

Deferred income
Deferred income is only recognised on non-cancellable contracts that provide unconditional rights to payment from the customer 
for products and services that the Company has not yet completed providing or that it will provide in the near future.

Revenue from product sales of hardware and perpetual software licences is recognised at the point in time when the customer 
has obtained control of the products sold. In the instances where the customer has been invoiced and revenue from hardware 
or perpetual software licences is unable to be recognised, revenue would not be recognised until control has passed, resulting 
in deferred income. 

Support services and software subscription agreements are generally billed at commencement of the support or subscription 
contract, while revenue is recognised over the period of the support or subscription agreement, resulting in deferred income.

The Company occasionally receives advance payments from customers on account, before products or services are delivered 
and revenue is recognised, resulting in liabilities. Deferred income and payments received on account are reported as contract 
liabilities within creditors on the balance sheet on a contract-by-contract basis at the end of each reporting period.

Government grants
A government grant is recognised in the balance sheet initially within creditors when there is reasonable assurance that it will be 
received and that the Company will comply with the conditions attached to it. Grants that compensate the Company for expenses 
incurred are recognised as other operating income on a systematic basis in the same periods in which expenses are incurred. 

Employee benefits
When an employee has rendered service to the Company during an accounting period, short-term benefits expected to be paid 
in exchange for that service are recognised in the same accounting period.

Share-based payment
The Company operates various equity-settled share-based compensation plans and accounts for these awards in accordance 
with IFRS 2 “Share-based Payment”. 

The fair value of these awards is recognised in the profit and loss account (or as an addition to the cost of investment in the 
subsidiary in which the relevant employees work) on a straight-line basis over the vesting period together with a corresponding 
change in equity. The fair value is measured using the Black-Scholes model by reference to the share price, and taking into 
account the terms and conditions of the award, excluding non-market vesting conditions, at the date the awards were granted. 
The charge is reassessed at each balance sheet date to reflect the expected and actual levels of vesting, due to achievement or 
otherwise of non-market conditions. Awards where vesting is conditional upon satisfying a market condition or non-vesting 
condition are treated as vesting irrespective of whether the market or non-vesting condition has been satisfied. 

The Company has an employee share trust for the granting of certain share incentives to employees. Shares in the Company 
held by the employee share trust are treated as treasury shares and presented in the balance sheet as a deduction from equity.

FINANCIAL STATEMENTS1. Significant accounting policies continued 
Tax
Income tax on the profit or loss for the year comprises current and deferred tax. Income tax is recognised in the profit and loss 
account except to the extent that it relates to items in other comprehensive income or equity.

Current tax is the expected tax payable on the taxable income for the year, using tax rates enacted or substantively enacted at 
the balance sheet date, and any adjustments to tax payable for previous years.

Deferred tax is recognised on all temporary differences arising between the tax bases of assets and liabilities and their carrying 
amounts in the financial statements, with the following exceptions:

•  where the temporary difference arises from the initial recognition of goodwill (taxable temporary differences only) or of an 

asset or liability in a transaction that is not a business combination that at the time of the transaction affects neither accounting 
nor taxable profit or loss; and

•  in respect of taxable temporary differences associated with investments in subsidiaries where the timing of the reversal of the 
temporary differences can be controlled and it is probable that the temporary differences will not reverse in the foreseeable future.

A deferred tax asset is recognised only to the extent that it is probable that taxable profits will be available against which the 
deductible temporary differences, carried forward tax credits or tax losses can be utilised.

Deferred tax assets and liabilities are measured on an undiscounted basis at the tax rates that are expected to apply when the related 
asset is realised or the liability is settled, based on tax rates and laws enacted or substantively enacted at the balance sheet date.

Dividends paid
The interim dividend is included in the financial statements in the period in which it is paid, and the final dividend and special 
dividend in the period in which it is approved by the shareholders at an Annual General Meeting.

Critical accounting judgements and key sources of estimation uncertainty
The preparation of financial statements requires the Company to make estimates and assumptions that affect items reported. 
Such estimates and assumptions are based on management’s best knowledge of current facts, circumstances and future events. 
Actual results may differ, possibly significantly, from those estimates. The areas requiring a high degree of judgement are 
revenue recognition, leases (note 14) and defined benefit pension plans (note 3). The area of estimation uncertainty are 
recognition of deferred tax assets (note 15). Please refer to note 2 of Notes to the consolidated financial statements on pages 131 
to 140 for detailed disclosures.

2. Employees
Please refer to the Report on Directors’ Remuneration on pages 83 to 110 and note 34 of Notes to the consolidated financial

Defined benefit plans
i) Characteristics and risks associated with the Plans
The Company sponsors two funded defined benefit pension plans in the United Kingdom: the Spirent Communications plc Staff 
Pension & Life Assurance Plan (“Staff Plan”) and the Spirent Communications plc Retirement Cash & Life Assurance Plan (“Cash Plan”). These 
plans are funded and have full UK HM Revenue & Customs (“HMRC”) tax-exempt approval. Both schemes are administered by a 
Trustee board which is comprised of representatives from the employer, member nominated Trustees and an independent Trustee. 
The Trustee board operates in accordance with the Trust Deed and Rules of each Plan and acts in the interests of all of its members. 

•  The Staff Plan is the Company’s most significant plan, and it provides its members with retirement benefits based on their final 

salary and length of service. The Staff Plan is closed to new entrants. 

•  The Cash Plan is complicated with multiple cohorts that allows members to benefit from a lump sum on retirement, a defined 

benefit contribution with a defined benefit underpin or pension. The Cash Plan is closed to new entrants.

There is also a UK unfunded plan, which consists of a contractual obligation for the Company to top up certain former 
employees’ benefits whose salaries exceeded the statutory earnings cap. 

As with the vast majority of similar arrangements in the United Kingdom, the Company ultimately underwrites the risks relating to 
the defined benefit plans. These risks include investment risks and demographic risks, such as the chance of members living 
longer than expected. 

The Cash Plan holds a significant proportion of its assets in equity. Strong future equity returns would be expected to reduce the 
Company’s future cash contributions (and vice versa). 

The latest triennial actuarial valuations dated 31 March 2021 indicated a combined funding deficit of £11.5 million, calculated on a 
technical provisions basis using more prudent assumptions than the accounting valuation, particularly in relation to the discount 
rate inflation and demographic. A deficit reduction plan was agreed with the trustees which required the Company to pay 
monthly contributions of £449,609, whilst a funding deficit remains, increasing in line with CPI each year. In September 2022, this 
deficit funding plan was suspended whilst the Company and trustees worked together to consider the feasibility of purchasing a 
bulk annuity insurance policy.

In October 2022, the Trustees with the Company’s support, purchased a bulk annuity insurance policy from specialist UK insurer 
Pension Insurance Corporation (PIC), in respect of the largest plan, the Staff Plan. The premium was met from the plan’s assets 
and sufficient assets remain to meet the plan’s ongoing costs. This pension buy-in secures an insurance asset from PIC that 
matches the remaining pension liabilities of the Staff Plan, such that the Company no longer bears any investment, inflation, 
longevity or other demographic risks. An asset remeasurement loss of £6.0 million has been recorded in other comprehensive 
income as the premium paid was greater than the IAS 19 accounting value of the corresponding liabilities. Following the purchase 
of the bulk annuity insurance policy, the Company does not expect to make any further cash contributions to this plan. Cash 
contributions to the plan in 2022 amounted to £0.9 million (2021 £5.4 million).

At 31 December 2022, a reserve of £3.0 million is included within the accounting position in respect of equalising historic GMP 
benefits. The ultimate cost to equalise benefits could be higher or lower than reserved (but not materially so), reflecting the 
considerable uncertainty in the way in which benefits will ultimately be equalised. The bulk annuity insurance policy purchased by 
the trustees does not currently include provision for equalising GMPs but there is a mechanism for them to do so once finalised. 
As updates are made the reserve the difference will be charged to other comprehensive income as an experience gain/loss.

a) The assets and liabilities in each plan continued
In 2021, approximately 60 per cent of the Staff Plan’s assets were held in a combination of LDI funds and cash benchmarked 
bonds. The objective of this allocation is to hedge against the plan’s liabilities, provide protection against inflation risk and 
provide a level of investment returns in all market scenarios.

These funds have a wide investment remit and as such the investments of the funds may or may not be listed on recognised 
exchanges and markets and will be without restriction as to geographical, industrial or sectoral exposure. These funds may take 
both long and short positions and may utilise a broad range of derivatives. The funds’ investments may include sub-investment 
grade securities, corporate debt securities, gilts, sale and repurchase agreements, loans, and emerging markets debt and currencies.

The plans are prohibited from investing in Spirent’s own financial instruments. 

The fair values of the quoted equity and debt instruments are determined based on quoted market prices in active markets 
whereas the fair values of the other assets are not. Unquoted investments are included at values provided by the fund managers 
and are generally valued using recent market data and external sources, with a hierarchy that follows the principles of IFRS 13 
“Fair Value Measurement”.

The Company has determined that it has an unconditional right to refund of surplus assets if the schemes are run off until the last 
member dies, on which basis IFRIC 14 does not cause any change in the balance sheet disclosures before tax.

For the purposes of the following disclosures, the Staff Plan and Cash Plan have been combined as the Cash Plan is immaterial

The £84.7 million loss on remeasurement of plan assets represents a £77.5 million reduction in asset values prior to the buy-in 
(the assets were invested to match the liability risk profile which also reduced significantly as interest rates rose), a £6.0 million 
loss due to the premium on buy-in exceeding the IAS 19 liability measure, a £2.0 million loss as the asset returns on the Cash Plan 
were lower than assumed under IAS 19 offset by a £0.8 million gain as the Staff Plan asset returns exceeded those assumed 
under IAS 19.

f) The key financial assumptions
The assumptions used for both plans using a weighted average were as follows:

Inflation – RPI
Inflation – CPI (pre-2030)
Inflation – CPI (post-2030)
Rate of increase in pensionable salaries
Rate of increase for pensions in payment pre-2001 service
Rate of increase for pensions in payment 2001 to 5 April 2005 service
Rate of increase for pensions post-5 April 2005 service
Rate of increase in deferred pensions
Rate used to discount plan liabilities

The mortality assumptions are based on standard mortality tables which allow for future mortality improvements. The assumptions 
are such that a member currently aged 65 (2021 aged 65) will live on average for a further 22.0 years (2021 22.2 years) if they are 
a male and for a further 24.5 years (2021 24.6 years) if they are female. For a member who retires in 2042 (2021 in 2041) at age 65 
(2021 aged 65) the assumptions are that they will live on average for a further 23.6 years (2021 23.8 years) after retirement if they 
are male and for a further 26.2 years (2021 26.3 years) after retirement if they are female.

iii) Amount, timing and uncertainty of future cash flows
The approximate impact to past service liabilities of these changes to the main assumptions, which are considered reasonably 
possible, is as follows:

•  Reducing the discount rate by 0.1 per cent per annum would increase past service liabilities by £1.6 million (2021 £3.2 million).

•  Increasing RPI inflation by 0.1 per cent would increase the plans’ liabilities by £0.6 million (2021 £1.2 million).

•  Increasing the life expectancy of a member by one year (by modifying the standard mortality tables using an appropriate 

scaling factor) would increase past service liabilities by £6.9 million (2021 £12.2 million).

The accounting valuation of the funded UK defined benefit pension plans as at 31 December 2022 gave rise to a net surplus of 
£10.9 million. Future changes to the valuation assumptions noted above may cause material impacts to the pension liability 
calculations, for example, the discount rate experienced a change of 3.0 per cent between 2021 and 2022.

iii) Amount, timing and uncertainty of future cash flows continued
There will also be an impact on the future service cost but given the small active population in these plans this is likely to be 
insignificant. The sensitivity analysis may not be representative of the actual change as the changes in assumptions may not 
occur in isolation.

The Directors consider that the carrying amount of trade debtors, amounts owed by subsidiaries and other debtors 
approximates their fair value.

The Company has no significant concentration of credit risk attributable to its trade debtors as the exposure is spread over 
a large number of customers.

Assets recognised from costs to obtain a contract relate to capitalised incremental costs to obtain a contract, being sales 
commissions arising on contracts with customers of more than one year in length. No assets were impaired or derecognised 
during the current year or prior year.

There was no revenue recognised in 2022, 2021 or 2020 from performance obligations satisfied in previous periods. 

The timing of revenue recognition, invoicing and cash collections results in trade debtors, payments received on account and deferred 
income on the balance sheet.

The Company receives payments from customers based on a billing schedule, as established in the contract. Trade debtors are 
recognised when the right to consideration becomes unconditional. Contract liabilities are recognised as revenue as (or when) 
the Company performs under the contract. 

The Company also recognises incremental costs incurred to obtain a contract as an asset if it expects to recover those costs. 
Such costs are presented within debtors in the balance sheet as assets recognised from costs to obtain a contract and disclosed 
in note 9. 

Expected realisation of remaining performance obligations at year end
The Company applies the practical expedient in paragraph 121 of IFRS 15 and does not disclose information about remaining 
performance obligations that have original expected durations of one year or less.

For contracts that exceed one year, deferred income that relates to unsatisfied or partially satisfied performance obligations 
at year end is expected to be recognised as revenue in the future as follows:

Within 1 year
Greater than 1 year

£ million

2021

The above information represents the revenue the Company will recognise when it satisfies the remaining performance 
obligations in the contracts. The amounts presented do not include orders for which neither party has performed.

Revenue from the sale of hardware and software generally arises from contracts less than one year in length. Consequently, 
the above amounts predominantly relate to the sale of maintenance and support services. 

Virtually all of the revenue will be recognised within three years. 

The Company provides standard warranties on its products and services. The nature of these warranties is considered to 
provide customers with assurance that the related product or service will function as intended in accordance with the agreed 
specification, and does not contain or imply any additional service obligation to the customer. Warranty obligations are 
estimated and recognised as liabilities based on the probable outflow of resources.

Extension options
Some leases of buildings contain extension options exercisable by the Group before the end of the non-cancellable contract 
period. Where practicable, the Group seeks to include extension options in new leases to provide operational flexibility. The 
extension options held are exercisable only by the Group and not the lessors. The Group assesses at lease commencement 
whether it is reasonably certain to exercise the extension options. The Group reassesses whether it is reasonably certain to 
exercise the options if there is a significant event or significant change in circumstances within its control.

In 2022 and 2021, the deferred tax liability and asset have been offset on the balance sheet as they related to income taxes 
raised by the same authority on the same taxable entity.

The Company has tax losses of £22.9 million (2021 £23.9 million) and short-term timing differences of £0.3 million 
(2021 £0.2 million) that are available for offset against suitable future taxable profits.

A deferred tax asset has not been recognised in respect of these losses as their future recovery is uncertain. These losses 
can be carried forward indefinitely.

The Company also has capital losses carried forward of £823.3 million (2021 £823.3 million) for which no deferred tax asset 
has been recognised on the balance sheet. These capital losses have no expiry date.

The Directors are proposing a final dividend in respect of the financial year ended 31 December 2022 of 4.12 pence per Ordinary 
Share (2021 3.34 pence), which will absorb an estimated £24.8 million of shareholders’ funds (2021 £20.3 million). The final 
dividend will be paid on 10 May 2023 to Ordinary shareholders who are on the Register of Members at close of business on 
17 March 2023. Payment will be made to ADR holders on 17 May 2023. No liability is recorded in the financial statements in 
respect of these dividends.

Dividends are determined in US Dollars and paid in Pound Sterling. The exchange rate for determining the amount of the 
final dividend to be paid for 2022 was $1.20: £1 (2021 $1.31: £1).

Investment in own Ordinary Shares
During the year, 7.1 million shares were purchased and placed into the Employee Share Ownership Trust at a cost of £19.3 million 
and 2.7 million shares were also transferred from the Employee Share Ownership Trust to satisfy options exercised under the Spirent 
employee share plans (2021 3.9 million shares purchased and placed at cost of £11.0 million, and 2.3 million shares transferred).

At 31 December 2022, the Employee Share Ownership Trust held 8.9 million Ordinary Shares (2021 4.5 million Ordinary Shares) 
to satisfy awards under various share incentive plans. At 31 December 2022, the Spirent Sharesave Trust held 0.5 million Ordinary 
Shares (2021 0.5 million Ordinary Shares) to satisfy awards made to United Kingdom-based employees under an all-employee 
share scheme. The market value of own Ordinary Shares held in trust, being in total 9.4 million Ordinary Shares (2021 5.0 million 
Ordinary Shares), at 31 December 2022 was £24.5 million (2021 £13.8 million).

Both the Employee Share Ownership Trust and the Spirent Sharesave Trust are an extension of the Company.

Employee share plans
The Company operates a number of employee share incentive plans which are described in note 30 of Notes to the

OTHER INFORMATIONAlternative performance measures

The performance of the Group is assessed using a variety of alternative performance measures (APMs) which are presented 
to provide users with additional financial information that is regularly reviewed by management. The APMs presented are not 
defined under IFRS and therefore may not be directly comparable with similarly identified measures used by other companies. 

In management’s view, the APMs reflect the underlying performance of the Group and provide an alternative basis for evaluating 
how the Group is managed and measured on a day-to-day basis. Such APMs are non-GAAP measures and should not be 
viewed in isolation or as an alternative to the equivalent GAAP measure.

The APMs and key performance indicators are aligned to the Group’s strategy and collectively are used to measure the 
performance of the Group and form the basis of the metrics for Director and management remuneration. The Group’s key 
performance indicators are presented within the Strategic Report of its 2022 Annual Report.

Order intake
Order intake represents commitments from customers to purchase goods and/or services from Spirent that will ultimately 
result in recognised revenue. Where there can reasonably be changes to the scope or duration of an order, the Group exercises 
judgement on the amount of the order that is booked.

Order intake is a measure of operating performance used by management to assess whether future activity levels are increasing 
or slowing and therefore how effective we have been in the execution of our strategy. Order intake is a key performance 
indicator used to measure Group, operating segment and regional performance for internal reporting purposes.

Orderbook
Orderbook comprises the value of all unsatisfied orders from customers and provides an indication of the amount of revenue 
that has been secured and will be recognised in future periods. Orderbook represents the transaction price allocated to wholly 
and partially unsatisfied performance obligations, including amounts held in contract liabilities at the period end. There is no 
comparable IFRS measure.

Book to bill
Book to bill is the ratio of orders booked to revenue recognised in the year and is a measure of the visibility of future revenues 
at current levels of activity. Book to bill is a key performance indicator used to measure Group and operating segment 
performance for internal reporting purposes.

Adjusted operating profit
Adjusted operating profit is reported operating profit excluding amortisation of acquired intangible assets, share-based 
payment and other adjusting items. Management uses adjusted operating profit, in conjunction with other GAAP and non-GAAP 
financial measures, to evaluate the overall operating performance of the Group as well as each of the operating segments and 
believes that this measure is relevant to understanding the Group’s financial performance, as specific items (adjusting items) are 
identified and excluded by virtue of their size, nature or incidence, as they are not considered part of the Group’s normal ongoing 
operations and therefore can lead to period-on-period fluctuations that can make it difficult to assess financial performance. 

Specifically, items are excluded from adjusted operating profit if they are acquisition related in nature, including acquired 
intangible asset amortisation which is dependent on being able to identify intangible assets and assessing their useful economic 
lives, or if their exclusion allows for more meaningful comparisons with peer companies such as share-based payment which 
can fluctuate from period to period. The exclusion of adjusting items from adjusted operating profit is consistent from period 
to period. 

Adjusted operating profit is also used in setting Director and management remuneration targets and in discussions with the 
investment analyst community. 

Adjusted operating margin
Adjusted operating margin is adjusted operating profit as a percentage of revenue. It is a measure of the Group’s overall 
profitability and how successful we are in executing on our overall strategy, and demonstrates our ability to improve margin 
through efficient operations and cost management, whilst being mindful of the need to invest for the future. 

Effective tax rate
Effective tax rate is the adjusted tax charge, before tax on adjusting items, expressed as a percentage of adjusted profit before 
tax. The adjusted tax charge is the reported tax charge excluding the tax effect on adjusting items and adjustments made to 
provisions in respect of prior year tax.

196

Spirent Communications plc Annual Report 2022

OTHER INFORMATIONAdjusted basic earnings per share
Adjusted basic earnings per share (EPS) is adjusted earnings attributable to owners of the parent Company divided by the 
weighted average number of Ordinary Shares outstanding during the year. Adjusted earnings is reported profit before tax 
excluding amortisation of acquired intangible assets, share-based payment, other adjusting items, tax on adjusting items and 
over/under provisions in respect of prior year tax. 

Adjusted basic EPS is a measure of how successful we are in executing on our strategy and ultimately delivering increased value 
for shareholders. Adjusted basic EPS is also used in setting Director and management remuneration targets and in discussions 
with the investment analyst community. The Group sets out the calculation of adjusted basic EPS in note 11 of Notes to the 
consolidated financial statements. 

Product development spend as a percentage of revenue
Product development as a percentage of revenue in the year. It is a measure of how much the Group is investing to support 
further organic growth initiatives in line with the strategic objectives, whilst driving improved productivity and effectiveness.

Free cash flow
Free cash flow is cash flow generated from operations, less tax and net capital expenditure, lease liability principal repayments 
and lease liability interest paid, add interest received and lease payments received from finance leases, excluding acquisition 
related other adjusting items and one-off employer contributions to the UK pension scheme.

Free cash flow is a measure of the quality of the Group’s earnings and reflects the ability to convert profits into cash and 
ultimately to generate funds for future investment. It gives us financial strength and flexibility and the ability to pay sustainable 
dividends to our shareholders. Free cash flow is an important indicator of overall operating performance as it reflects the cash 
generated from operations after capital expenditure, financing and tax which are significant ongoing cash flows associated with 
investing in the business and financing operations.

Free cash flow excludes corporate level cash flows that are independent of ongoing trading operations such as dividends, 
acquisitions and disposals and share repurchases and therefore is not a measure of the funds that are available for distribution 
to shareholders.

A reconciliation of cash generated from operations, the closest equivalent GAAP measure, to free cash flow is provided within the 
Financial Review on page 53.

Free cash flow conversion
Free cash flow conversion is the ratio of free cash flow to adjusted earnings, presented as a percentage. 

Free cash flow conversion is a measure used in conjunction with free cash flow to assess the Group’s ability to convert profit into 
cash and ultimately to generate funds for future investment.

Cautionary statement regarding forward-looking statements 
This Annual Report may contain forward-looking statements which are made in 
good faith and are based on current expectations or beliefs, as well as assumptions 
about future events. You can sometimes, but not always, identify these statements 
by the use of a date in the future or such words as “will”, “anticipate”, “estimate”, 
“expect”, “project”, “intend”, “plan”, “should”, “may”, “assume” and other similar 
words. By their nature, forward-looking statements are inherently predictive and 
speculative and involve risk and uncertainty because they relate to events and 
depend on circumstances that will occur in the future. You should not place 
undue reliance on these forward-looking statements, which are not a guarantee 
of future performance and are subject to factors that could cause our actual 
results to differ materially from those expressed or implied by these statements. 
The Company undertakes no obligation to update any forward-looking 
statements contained in this Annual Report, whether as a result of new 
information, future events or otherwise.

Spirent Communications plc’s commitment to environmental issues is reflected in 
this Annual Report, which has been printed on Magno Satin, an FSC® certified 
material. This document was printed by Pureprint Group using its environmental 
print technology, which minimises the impact of printing on the environment. 
Vegetable-based inks have been used and 99% of dry waste is diverted from 
landfill. The printer is a CarbonNeutral® company. Both the printer and the 
paper mill are registered to ISO 14001.
