chairman’s statement
at the end of my ﬁrst ﬁnancial year as 
chairman i’m pleased to report that we 
have made a good start to delivering  
our targets for the new amp5 regulatory 
period and are realising the beneﬁts of  
our efﬁciency improvement programmes 
as expected the price reductions at the 
start of the ﬁve year determination have 
reduced proﬁtability below prior years’ 
levels but from this base severn trent 
water has continued to outperform
for the year total group turnover was up 
04 to £17 billion the real price reduction 
in the ﬁrst year of the new amp has 
rebased underlying proﬁtability with group 
proﬁt before tax gainslosses on ﬁnancial 
instruments and exceptional items down 
147 to £2886 million giving adjusted 
earnings per share excluding deferred tax 
of 1056p a 14 decrease on the prior year
this is a good solid business on track  
to perform well and deliver total overall 
beneﬁts for shareholders customers and 
the environment
there remains signiﬁcant opportunity for 
growth in both our services business and 
in delivering further outperformance in 
severn trent water

overview
i am delighted to ﬁnd at severn trent a 
strong board of executives very capably  
led by tony wray that is committed to 
operational excellence and continuous 
improvement momentum within the 
company is strong and we have the 
ambition to be recognised as a top 
performer in our sector i am also grateful to 
the management team for the wholehearted 
support that they have given to me in my 
ﬁrst year as chairman
we have a solid track record of ﬁnancial 
performance and the board is proposing a 
ﬁnal dividend of 3905p to be paid on 29 
july 2011 this will give a total dividend of 
6509 pence per ordinary share from this 
new base we will look to grow the dividend 
by 3 above rpi each year up to 201415 
the single largest proﬁt driver was the 
performance of severn trent water which 
continued to outperform with planned 
operational expenditure below the level of 
the final determination 
this improvement in efﬁciency is a 
consequence of the group’s ongoing change 
programme which is resulting in signiﬁcant 
business improvement one of the most 
momentous changes during the year was 
the move to our new operating centre in 
coventry resulting in not only a change  
of environment for our people but a  
change to new more efﬁcient and 
innovative working practices i’ve yet to 
meet a visitor who isn’t impressed by this 
truly modern working environment and the 
building has created a level of energy and 
enthusiasm that is infectious
the change programme extends beyond 
the ofﬁce to the group’s operations and 
processes and includes signiﬁcant systems 
investment naturally as with many 
programmes of this size and scale it comes 
with its challenges but we’re conﬁdent we 
have embarked upon a course that will allow 
us to continue to deliver further efﬁciencies 
throughout the amp period
operational performance during the year 
was impacted by the severe winter weather 
placing pressure on our leakage 
performance during the year the number of 
unplanned interruptions to customers’ water 
supply increased we have decided to 
increase the level of investment in our water 
distribution system in order to build even 
greater resilience in our infrastructure to 
cope with severe weather in future years 
severe weather notwithstanding however 
we continue to provide some of the highest 
standards of customer service in the 
industry with excellent drinking water quality 
and a year on year reduction in the number 
of properties suffering from sewer ﬂooding 
i am particularly pleased to see the focus  
on health and safety within the business 
the personal safety of employees has 
always been one of my priorities so i was 
pleased to ﬁnd a strong culture and focus on 
safety in the company our recent employee 
engagement survey shows that 95 of our 
people say that health and safety is taken 
seriously at severn trent water and this is 
reﬂected in the severn trent water lost 
time incident lti performance which 
remains the best in the sector safety is one 
issue but the commitment of our employees 
is vital to our group’s success and so we are 
continuing to invest in the development and 
training of our employees and future leaders
during the year we made good progress in 
protecting our environment and dealing with 
waste water whilst continuing to lead the 
industry in the production of renewable 
energy selfgenerated renewables now 
supply 22 of severn trent water’s power 
requirements helping to mitigate our  
carbon impact 
severn trent services had a mixed year 
with performance falling below expectations 
although the business made good progress 
in reducing its costs and maintains a strong 
order book results were affected by project 
delays in our middle east and north africa 
region and the slowdown in the global 
economic environment impacting public 
funded initiatives growth and proﬁtability  
in our services business remains a priority 
and we are well placed to make progress  
on this aim 
as i write this statement it seems likely that 
there will be some regulatory change 
following the publication of the government’s 
white paper later this year we intend to 
continue to play an active role in regulatory 
reform and play an inﬂuential role in the 
debate about how our industry addresses 
the challenges ahead of us in order to 
promote sustainable growth we also want 
to make sure that any change strikes the 
right balance between delivering value and 
security to our customers and reliable 
returns to our shareholders we must get 
this right because the investment challenge 
over future years means that we must be 
able to compete for capital internationally as 
the need for infrastructure funding globally 
becomes more pressing you can read 
more about our position on page 20 of  
this report
all of this will undoubtedly bring more 
challenges but i ﬁrmly believe that we have 
the talent the innovation the systems and 
the resources to continue to achieve 
proﬁtable and sustainable growth for our 
group whilst also meeting the needs of our 
customers and the environment

chief executive’s review
our strategy of sustainable growth 
through a focus on water and waste  
water operations in the uk and 
internationally continues to deliver 
signiﬁcant overall value
in the uk severn trent water made  
a good start to the new ﬁve year  
regulatory period performing broadly  
in line with expectations 
in a challenging year i would like to  
pay tribute to our people who 
professionally handled both difﬁcult 
operational circumstances and  
signiﬁcant internal change
our severn trent services business 
started the year strongly but was  
affected by the economic slowdown  
and political and regulatory uncertainty  
in the second half 
fundamentally we remain well placed  
to deliver our business plan and to 
continue to play an active role in shaping 
the future of the uk water industry

overview
business performance review
group proﬁt before interest tax and 
exceptional items is down 7 due to 
expected price reductions in the ﬁrst year  
of the amp period for severn trent water 
and a disappointing second half 
performance in severn trent services  
in challenging market conditions
from the new dividend base of 6509p we 
will grow the dividend by 3 above rpi up 
to 201415 
underlying ﬁnancial performance remains 
strong and we continued to outperform our 
regulatory targets
severn trent water
with our focus on operational excellence 
and continuous improvement our goal is  
to keep prices low and deliver the highest 
customer service and environmental 
standards
overall we achieved these goals in the past 
year we delivered industryleading drinking 
water quality and reduced the number of 
incidents of sewer ﬂooding one of the 
biggest causes of distress to our customers 
our customers also beneﬁted from the 
lowest combined average water and 
sewerage bills in england and wales
in these straitened times we’ve carried  
on helping customers who have difﬁculties 
paying their bills and as a result we have 
also been able to reduce bad debt
environmental performance continues to  
be strong and we are reinforcing our leading 
position in renewable energy generation 
with 22 of severn trent water’s electricity 
requirements being met by selfgenerated 
renewables some of that was generated  
by the uk’s ﬁrst commercial scale crops to 
energy plant which was opened this year 
leakage was above target as a result of the 
severe winter weather however despite 
signiﬁcant operational challenges we 
maintained our leakage at the same level as 
last year unplanned interruptions to supply 
also increased during the year 
steps are in place to improve the resilience 
of our water distribution network but i would 
like to pay tribute to our people who faced 
with unprecedented operational challenges 
kept customer supplies running over this 
difﬁcult period 
that we are able to work in such a ﬂexible 
and responsive way is thanks in part to the 
changes we have made to our internal 
operations this year we moved to our new 
operating centre severn trent centre in 
coventry bringing together under one roof 
many teams previously dispersed over 
seven older buildings we have transformed 
our technology infrastructure and 
implemented the second phase of sap 
which will help us to run our business more 
effectively
once again i would like to use this 
opportunity to thank our people for the way 
they have responded to such a signiﬁcant 
change in technology and ways of working
severn trent services
the economic environment remained 
especially challenging for our severn trent 
services business which started the year 
well only to experience a market downturn  
in the second half
while the underlying market is growing and 
demand remains strong projects are being 
delayed as project ﬁnancing has been less 
available and slower to obtain in addition 
political uncertainty in the middle east a key 
market for our water puriﬁcation products 
and the moratorium on deep well drilling  
in the us led to lower sales of our highly 
successful electrochlorination product line 
in the us in particular municipal budget 
shortfalls have limited infrastructure 
spending on products while driving more 
project opportunities for outsourcing in our 
operating services units
looking ahead
at severn trent water with strong 
underlying performance and the right 
people technology and amp5 contracts  
in place we are well placed to achieve  
our business plan and outperform our 
regulatory targets 
in severn trent services the prospects for 
long term growth remain good but the ﬁrst 
half of the coming year is likely to see the 
same market conditions that prevailed at the 
end of last year with a good portfolio of 
business and products we are conﬁdent  
of returning to proﬁtable and sustainable 
growth once the public ﬁnances start to 
recover and the political and regulatory 
uncertainty in key markets subside
in terms of prospects for regulatory and 
industry change severn trent remains at 
the forefront of industry thinking and our 
ideas for a sustainable future for our  
industry have been widely published  
and well received 
throughout our operations our goal 
continues to be to deliver long term 
sustainable growth this strategy 
underpinned by a clear focus on customers

shareholder value will continue

efﬁciency gains
we are always looking for ways to improve 
our standards and operate more efﬁciently 
we achieve this through supply chain cost 
reduction in component sourcing and lower 
cost locations for engineering and 
assembly and by improving our

changes to the regulatory and policy 
framework are now needed in order to make 
the industry sustainable our strategy of 
continually improving our operational and

severn trent water
performance
our aim is to deliver the highest standards 
and lowest prices for customers and one of 
the best standards of drinking water in the 
uk at an average of £298 severn trent 
water customers also paid the lowest 
average combined water and sewerage bill 
in england and wales over the last year 
for those customers struggling to pay we 
helped to manage their payments whilst 
reducing our own bad debt risk
the harsh december had a signiﬁcant 
impact on our operations particularly on 
our leakage performance with a sharp 
peak in leakages at the height of the 
freezethaw events the severe weather 
also meant that our capital programme got 
off to a slower start than we had aimed for
we are particularly pleased with progress 
in our work to tackle sewer ﬂooding one  
of the biggest causes of disruption and 
distress to our customers we also halved 
the total number of pollution incidents in the 
category 1 and 2 bands with none in the 
most serious category 1 classiﬁcation
our business also underwent change 
during the year as we set up to deliver  
our ambitious amp5 programme our 
streamlined new supply chain is now  
in place and major improvements in 
technology and ways of working have been 
implemented including the move to a state

side of dealing with our customers – we 
aim to deal with customer issues at ﬁrst

business and economic 
environment together with  
the coldest december in  
100 years however overall 
progress remains strong with 
signiﬁcant business change

case study 
transferring sewer 
ownership
we anticipate the transfer of 
private drains and sewers 
pdas will take place in 
october 2011 at the moment 
home owners are responsible 
for everything up to the main 
sewer including the 
connection after the transfer 
we will own around 37 000km 
of sewers which are currently 
privately owned and be 
responsible for their repair 
and maintenance we also 
expect roughly 4000 
pumping stations to be 
transferred in stages over the 
following ﬁve years we 
believe this will beneﬁt some 
customers in a number of 
ways such as reducing their 
liability and repair costs  
but will lead to higher bills  
in general to fund the 
necessary continued 
investment our plans for the 
transition are well advanced 
and we have been engaging 
with regulators and 
government to make sure  
we provide customers with 
an efﬁcient service after  
the transfer
customer experience
we are committed to providing the best 
customer experience possible ofwat’s 
service incentive mechanism sim a new 
way of measuring the customer experience 
will help us keep track of our performance  
it measures whether our customers feel 
valued when we interact with them as well 
as how well we respond to their telephone 
and written communications the 201011 
ﬁnancial year is our ﬁrst full year of data  
we are using the information we gather to 
put together a customer experience 
programme that covers recruitment training 
our telephone performance and improving 
every single touch point customers have 
with severn trent 
at times and especially during the harsh 
winter our customers found it difﬁcult to 
contact us as we were inundated with calls 
from people with frozen domestic pipes 
this has increased complaints which we  
are working hard to resolve 
a continuous supply of quality water
in 2010 we delivered 9998 overall mean 
zonal compliance with dwi drinking water 
quality regulatory standards however  
our unplanned interruptions to supply 
performance over the year was not at the 
level we expect three major events caused 
signiﬁcant disruption and regrettably a 
number of our customers were without 
water for some time we have a dedicated 
programme in place to improve performance 
flooding and pollution 
we are ahead of our target for reducing the 
number of properties on the sewer ﬂooding 
risk register thanks to investments in our 
network and our proactive monitoring which 
allows us to identify and ﬁx problems before 
they result in failure we have reduced the 
number of network failurerelated repairs by 
15 resulting in less disruption to customers 
and reduced ﬂooding and pollution 
managing debt
our challenge is to reduce bad debt while 
helping people who genuinely want to pay 
but are ﬁnding it difﬁcult to meet their 
payments in 2010 we introduced a new 
credit management system that helps us 
target our efforts more efﬁciently along with 
our relationships team which works with 
social housing landlords to track tenants 
moving in and out of rented accommodation 
and stay on top of debt in this sector we 
reduced bad debt to 23 of sales our 
region is still feeling the effects of the 
economic change the country is currently 
experiencing and for this reason our outlook 
on debt reduction is cautious
to help people on lower incomes who want 
to be good payers but have fallen into debt 
we are piloting the new together tariff

case study 
improving river water 
quality 
a £9 million project to 
upgrade our sewerage 
network and improve the 
water quality of the river 
tame unearthed several 
hurdles at the feasibility study 
stage these included 
contaminated ground buried 
concrete structures the 
presence of great crested 
newts and a complex 
geology with a past history of 
deep coal mining and high 
groundwater levels we 
worked with the environment 
agency and the local 
authority to secure an 
agreement to reuse all 
excavated material on site 
delivering a huge reduction in 
the project’s carbon footprint 
collaborating with our 
contractor also enabled us  
to introduce several 
innovations such as 
specialist covers to the tank 
and control of groundwater 
environment 
our customers should have conﬁdence that 
we will take away waste water and treat it to 
the highest environmental standards before 
returning it to our region’s rivers we also 
strive to run our operations in a sustainable 
way and reduce our carbon footprint 
during the year we made good progress  
in protecting our environment and dealing 
with waste water whilst continuing to lead 
the industry in the production of renewable 
energy however severe winter weather 
impacted our leakage performance in  
what was otherwise a year of improved 
environmental performance
dealing with waste water
during the past 12 months we have had a 
strong focus on continuous improvement 
which has resulted in us halving the  
number of serious pollution incidents from 
eight to four in the year with no category  
1 pollutions we have been working on 
improved processes for identifying 
monitoring and reporting pollution and our 
self reporting has increased by 11 we are 
conﬁdent that this is helping us to focus on 
the right things and whilst this has led to an 
overall increase from 322 to 378 reported 
pollution incidents we are conﬁdent that this 
is due to raising our standards of working 
and improving our understanding such  
that in the longer term we will deliver  
better overall performance
an £82 million investment to resolve 
pollution from our sewers overﬂowing in 
rivers and streams will lead to a further 
signiﬁcant improvement in river quality  
in the region
our sewage treatment works failing consent 
limit was 169 2010 180 we are 
working to improve this as part of our 
environmental improvement plan which we 
put in place this year our plan developed 
alongside ofwat supports our aim of raising 
the standards of our watercourses to beneﬁt 
local communities and those who use our 
rivers for recreation
one of our challenges is striking a balance 
between river water quality and carbon 
production we invest in plant to eliminate 
nitrates and pesticides in order to improve 
water quality in our rivers and comply with 
the water framework directive wfd to 
reduce the number of new treatment works 
we need to build we work in partnership 
with farmers and industries to encourage 
them to discharge less efﬂuent and waste 
into watercourses through the use of 
catchment management investigations 
cmi severn trent is currently engaged  
in 47 cmis more than any other water

protecting the biodiversity of our region
the scale and scope of our operations puts 
us in a unique position to protect and often 
enhance the biodiversity of our region 
particularly its aquatic ecosystem there are 
over 800 sites of special scientiﬁc interest 
sssi in our region a number of which are 
nominated as sites of european importance 
for the conservation and protection of 
endangered species we own or partly 
manage 37 sssis and work in partnership 
with natural england countryside council 
for wales our tenants and other partners to 
safeguard the special interest of these sites 
reducing leakage
we experienced the coldest december  
in 100 years with signiﬁcant snowfall and a 
prolonged freeze across our region the 
graph below shows how leakage increased 
sharply compared to previous years this 
caused severe operational difﬁculties but we 
kept customers on supply throughout the 
winter however two freezes followed by 
two thaws caused leakage to rise to 
unprecedented levels we were able to 
maintain leakage at last year’s levels of  
497 megalitres per day mld however 
despite deploying additional resources we 
were unable to achieve our leakage target  
of 483 mld as a direct result of the weather 
we have reduced leakage signiﬁcantly  
since the winter and we have plans in  
place to achieve our targets in 201112  
our long term trend on leakage is good  
and we are conﬁdent of hitting our targets  
in future years
customers also have a part to play and  
our water conservation and efﬁciency 
programme has resulted in one of the  
lowest per capita water usages in the uk 
severn trent water customers use an 
average of 126 litres per day compared  
to the national average of 146 litres
reducing our carbon footprint
in 201011 we met our target of producing 
22 of severn trent water’s energy 
requirements from renewables reinforcing 
our leading position in the production of 
renewable electricity from sewage  
the group also delivered the uk’s ﬁrst 
commercial scale ‘energy crop’ power  
plant using maize and wheat to generate  
15 gigawatt hours gwh of electricity  
per annum enough to power 4500 homes  
the group has recently received permission 
to build its ﬁrst wind turbine which will  
help us achieve the goal of 30 of severn 
trent water’s power requirements being 
generated from our own renewables  
by 201415
as well as reducing our carbon impact 
renewables will also offer protection against 
rising energy prices reducing our exposure 
in volatile energy markets and saving 
around £28 million over the next ﬁve years 
in addition to generating our own energy  
we also set targets and monitor energy use 
across every area of our business our 
people take every opportunity to reduce 
energy from turning off lights to reducing 
unnecessary journeys we continue to 
invest in trackers and software that routes

over the past 12 months we have taken 
signiﬁcant steps to transform the way we 
work from the environment our people work 
in to the processes and technologies we 
use this is a vital part of our strategy to 
improve our performance and operational 
efﬁciency and the service we provide to our 
customers any change on this scale is 
bound to be challenging but overall our 
people are embracing the new working 
arrangements and once again showed 
exceptional commitment over a difﬁcult 
winter period 
a new way of working
in october we moved to the severn trent 
centre in coventry one of the most energy 
efﬁcient buildings in europe it reﬂects our 
ethos of openness team working high 
standards and low charges we also 
transformed our technology infrastructure 
virtual desktops allow our employees to 
access their pcs and business systems 
from any desk at a large proportion of our 
sites it also allows us to form teams 
dynamically to resolve speciﬁc problems 
for example during the extreme cold 
weather the technology allowed our people 
to rapidly form work groups and share 
information we are now using these 
working arrangements as a template to 
modernise the rest of our sites through our 
ongoing workplace improvement plan
improving our technology and  
business processes
throughout the year we continued to invest 
strategically in new technology completing 
the implementation of our new sap 
workforce management systems refreshing 
our desktop technology providing high 
bandwidth telecoms infrastructure and new 
data centres the adoption of new lower 
running cost technology has increased 
reliability and performance at a lower 
operating cost
the new sap workforce scheduling 
technology and processes are starting to 
make our operational teams more 
productive and our investment in sap’s 
asset management systems is contributing 
to improved capital programme efﬁciencies
our new systems and technology are 
fundamentally changing the way we work 
and so we have invested heavily in training 
our people to equip them with the right skills 
to exploit the new technology and systems
throughout our business our teams are 
improving their performance by changing 
the way they work using our ‘safer better 
faster’ approach to continuous 
improvement with more than two thirds of 
the organisation now upskilled in the tools 
and techniques managers and their teams 
are equipped to improve their processes to 
deliver higher standards of performance to 
our customers in the most cost effective 
ways they can the approach is now being 
introduced into our business support areas 
the success of this programme is due to the 
involvement and engagement of our people 
in making the improvements for themselves 
– taking ownership of their performance 
learning new tools and techniques  
and working more collaboratively with 
colleagues in different functions to  
solve problems

during the year our health and safety 
performance despite remaining at upper

improve this is the ﬁrst time in a number  
of years that we have not seen a year on 
year improvement and we are seeking to 
address the identifying causes to enable  
the business to attain further progress in  
this important performance measure 
importantly we have a strong culture of 
people taking personal responsibility for 
their own health and safety and that of 
others this year 95 of our workforce 
agreed that health and safety is taken 
seriously and 87 said we give them  
the right support to do their job safely  
we have introduced better health 
surveillance processes as part of improving 
our employees’ wellbeing but recognise that 
while we have made positive progress we 
have more to do in this area
recruitment and training
having the right people with the right skills is 
more important than ever we are working 
to make sure we have a more diverse 
workforce with a particular focus on 
attracting more female candidates for 
operational and senior roles in 2010 we

employees and new joiners and worked to 
embed the importance of diversity within our 
business with the help of acas we have 
designed and are implementing diversity 
training events that will eventually train 500

893 managers and potential leaders this 
year current managers have access to

people health and safety
to meet the aims of our growth strategy 
we need to recruit and develop a talented 
and motivated workforce and provide them 
with a safe and rewarding place to work 
we were therefore delighted that in our 
employee engagement survey severn 
trent services outperformed many other 
industry and country benchmarks results 
of the independently run survey show that 
the majority of our employees are proud to 
work for us and 90 feel we meet the 
needs of our customers
given our strategy to embed health and 
safety in all areas of our business we were 
particularly pleased that 95 of our 
employees take personal responsibility for 
working safely and 90 are aware of their 
responsibility to protect the environment  
in january we set up a multi level task 
team to suggest ways we could continue  
to improve our health and safety 
performance incorporating their 
recommendations into our health and 
safety plans for 201112

climate change
whether it’s the energy we use the water 
we supply to our customers or the quality  
of the diverse environment under our 
stewardship our business both contributes 
to and is affected by climate change on 
the question of water scarcity our strategy is 
to reduce demand and improve the ﬂexibility 
of our network before developing new 
sources for instance by encouraging our 
customers to use water sensibly we have 
one of the lowest per capita consumptions 
of water in the uk 
however valuable these measures they are 
not enough on their own water companies 
need to think differently in order to tackle 
climate change and arrive at more 
sustainable solutions
water trading
changing weather patterns are predicted  
to lead to hotter drier summers and wetter 
winters this will mean less water being 
available at different times of the year our 
last water resources management plan 
showed that over the next 25 years severn 
since privatisation our industry 
has experienced two decades 
of improvement but the world 
today is a very different place 
and if we are to meet our vision 
of creating a sustainable water 
industry  we need some 
changes we are playing an 
active role in shaping the future 
of the water industry in the uk
trent will face a shortfall of 232 million  
litres a day because of climate change  
and population growth if we do not do  
things differently 
but this is not just a problem for severn 
trent it is one for the nation as a whole 
one change we would like to see is more 
water trading water companies could trade 
resources nationally using water from areas 
of lower cost to higher cost with the right 
regulatory regime we believe it would be 
possible to use existing networks to move 
water from one region to another 
intelligent funding
there is no doubt that over the next 20 
years the water industry will need to 
maintain signiﬁcant investment in 
infrastructure in order to improve network 
resilience and reach higher environmental 
standards
initiatives like water trading and more ﬂexible 
outcomebased regulation will help avoid 
unnecessary capital investment but the 
sector’s continuing ability to deliver its 
investment programmes relies on its being 
able to fund them we believe that 
continuing to ﬁnance the programme 
entirely from borrowing is unsustainable 
putting pressure on credit ratings and 
passing on risk to customers equity 
participation remains as important as ever 
long term sustainable returns need to 
reﬂect this reality
severn trent continues to address the 
medium and longer term challenges facing 
the industry and published its views in its 
publication ‘changing course’ this 
document is available for shareholders to 
read and copies may be obtained from the 
company secretary or electronically at 
wwwseverntrentcom some of the  
key highlights from that document are 
presented below
over the past 20 years our industry has 
seen improved customer standards 
environmental performance and service 
quality and become more efﬁcient water 
companies have also successfully funded 
an investment programme valued at around 
£85 billion however these improvements 
have come at a cost 
customer bills have risen energy use  
has increased by 113 and the industry  
as a whole is managing debts of some  
£33 billion on top of that the reality of 
climate change is already having an impact 
on our business to carry on in the same 
way would not be sustainable that is why 
we published our document changing 
course in 2010 setting out our position and 
outlining the six key changes we believe are 
needed to address the challenges we face
later this year the uk government is due to 
publish its white paper while we do not 
know what recommendations it will contain 
we are pleased with the response to 
changing course and encouraged by the 
development of the debate over water 
trading and policy making 
‘ the debate over  
the next 20 years 
will be about 
security of supply’
michael mckeon  
finance director
‘ we’re beyond the 
point of whether you 
believe in climate 
change or not  
the reality is we  
are experiencing 
more extremes and 
we have to ﬁnd 
ways to cope’

business review
competition and consolidation
bringing about the kind of changes we 
believe our industry needs would require a 
change in the structure and regulation of the 
water sector the framework of incentives 
and output setting under the existing regime 
can mean that more sustainable solutions 
are overlooked in favour of capital intensive 
solutions faced with the choice of sourcing 
lowcost water elsewhere or building a 
reservoir companies often opt to build a 
reservoir this then becomes part of the 
regulated asset base allowing water 
companies to increase pricing 
we believe it would be better to encourage 
sustainable solutions that beneﬁt customers 
and the environment a gradual move 
towards a marketbased framework and 
competition within the sector would enable 
water companies to make best use of 
resources nationally rather than regionally 
such a move would help maintain investors’ 
conﬁdence in our industry and avoid an 
increase in the cost of capital 
as a water company we are unusual in that 
we are already able to supply water to large 
commercial and industrial companies 
across england and wales through severn 
trent services our expertise in commercial 
markets together with our conﬁdence about 
embracing the future and our operational 
ﬁnancial and strategic strength mean we are 
well placed to adapt to any structural or 
regulatory changes in our industry indeed 
we are looking forward to the opportunities 
the future will bring both in the regulated 
and commercial spheres
‘ the companies will 
need to plan 
innovate and deliver 
services in new and 
more sustainable 
ways and that 
means the regulatory 
environment we 
provide needs to 
change as well’

changing course – six key 
changes required to meet 
future challenges
policy changes
• more ﬂexible 
implementation of eu 
directives to ensure a 
better trade off between 
costs and carbon 
emissions
• developing competition 
through water trading  
this would also optimise 
resources nationally rather 
than just regionally
regulatory changes
• a more ﬂexible approach 
to environmental consents 
to allow for more cost 
effective approaches
•  an improved price setting 
process to provide the right 
incentives for sustainable 
ﬁnancing more 
sustainable solutions and 
increased innovation
industry changes
• companies must take the 
lead in driving innovation 
both in terms of the 
strategic and technical 
solutions they pursue and 
in shaping the wider 
direction the sector takes
changes to the institutional 
framework
• government should 
prioritise national policy 
outcomes and ensure the 
regulatory framework is  
set up to deliver them

crisis and many but not all ﬁnancial activities and markets have 
returned to what may be considered normal levels however we are 
yet to see the return of a fully functioning commercial paper market 
and have continued to support our liquidity position by holding cash 
reserves from earlier bond market issuances in other areas we are 
yet to see any material effect on the ﬁnances of our customer base 
from the package of measures the uk government has announced 
on public spending indeed we have improved our customer

exceptional items
there were net exceptional charges in the year to 31 march 2011  
of £214 million £497 million comprising
restructuring costs
• a charge of £130 million in severn trent water arising from 
programmes to restructure and realign the business and
• a charge of £07 million in severn trent services from the 
programmes to restructure the water puriﬁcation and analytical 
services businesses
regulatory matters
• a charge of £38 million in severn trent services arising from  
the group’s response to an audit in september 2010 by the 
drinking water inspectorate dwi of aspects of the services 
provided by severn trent laboratories limited from its bridgend 
laboratory and
• a charge of £39 million in corporate overheads arising from the 
group’s response to a request from ofwat to provide certain 
information under the competition act in connection with severn 
trent laboratories limited’s contracts with severn trent water 
limited and certain other water companies
net ﬁnance costs
the group’s net ﬁnance costs were £2306 million compared to 
£2188 million in the prior year the group has ﬁxed the interest rate 
of its non indexlinked debt for the ﬁve year period to march 2015 
the group’s cost of indexlinked debt is however linked to the 
movement in the retail prices index rpi this debt provides an 
economic hedge for severn trent water’s revenues and regulatory 
asset values that are also rpi linked under its regulatory regime 
the increase in the full interest charge is therefore largely due to 
higher interest charges on indexlinked debt as inﬂation was higher 
than the prior year and in addition average group net debt 
increased during the year the effective interest rate for 201011  
was 64 58 of which cash interest cost is 50 vs 54 in  
the prior year
proﬁt before tax
underlying group proﬁt before tax decreased by 147 to £2886 
million £3384 million group proﬁt before tax was £2530 million 
£3344 million
taxation 
the total tax credit for the full year was £215 million charge of 
£829 million of which current tax represented a charge of £321 
million £407 million and deferred tax was a credit of £536 million 
£422 million
a prior year tax credit amounting to £344 million arose during the 
year mainly as a result of the agreement of open tax positions 
covering a number of years
the effective rate of current tax excluding prior year items and 
exceptional items calculated on proﬁt before tax exceptional items 
and gainslosses on ﬁnancial instruments was 244 226 the 
change in effective rate is as a result of lower capital allowances in 
severn trent water
going forward we expect the effective current tax rate for 201112  
to be in the range of 26 to 27

the fair value of the group’s borrowings at 31 march 2011 is 
estimated to be £46718 million £4267 9 million compared to the 
book value of £43444 million £41765 million the group’s debt 
instruments are not traded in an active market and hence the fair 
value disclosed above is based on a theoretical discounted cash 
ﬂow calculation and does not represent an estimate of the amount 
for which the debt could be settled
treasury management and liquidity
the group continues to monitor liquidity carefully at 31 march 2011 
the group had £3152 million in cash and cash equivalents the 
group also has an undrawn £500 million committed bank facility of 
which £417 million expires in 2012 with the balance maturing in 
2013 average debt maturity is around 16 years the group is 
funded for its investment and cash ﬂow needs up to march 2013
cash is invested in deposits with highly rated a banks and 
liquidity funds and the list of counterparties is regularly reviewed and 
reported to the board
treasury policy and operations
our treasury affairs are managed centrally and in accordance  
with our treasury procedures manual and policy statement the 
treasury operation’s role is to manage liquidity funding investment 
and our ﬁnancial risk including risk from volatility in interest and to a 
lesser extent currency rates and counterparty credit risk the board 
determines matters of treasury policy and its approval is required for 
certain treasury transactions
our strategy is to access a broad range of sources of ﬁnance  
to obtain both the quantum required and lowest cost compatible  
with the need for continued availability our principal operating 
subsidiary severn trent water is a long term business 
characterised by multi year investment programmes our strategic 
funding objectives reﬂect this and the liquidity position and the 
availability of committed funding are essential to meeting our 
objectives and obligations we therefore aim for a balance of long 
term funding or commitment of funds across a range of funding 
sources at the best possible economic cost
the group’s current policy for the management of interest rate risk 
requires that no less than 45 of the group’s borrowings should be 
at ﬁxed interest rates or hedged through the use of interest rate 
swaps or forward rate agreements at 31 march 2011 interest rates 
for some 76 of the group’s net debt of £38688 million were ﬁxed 
in this way
we use ﬁnancial derivatives solely to manage risks associated with 
our normal business activities we do not hold or issue derivative 
ﬁnancial instruments for ﬁnancial trading
except for debt raised in foreign currency which is fully hedged our 
business does not involve signiﬁcant exposure to foreign exchange 
transactions we have investments in various assets denominated 
in foreign currencies principally the us dollar and the euro our 
current policy is to hedge an element of the currency translation risk 
associated with certain foreign currency denominated assets
we have entered into energy swaps that ﬁx the cost of substantially 
all of severn trent water’s expected net electricity consumption for 
the next three years and part of its anticipated consumption for the 
following year the price ﬁxed in these swaps is lower than the 
amount assumed in the final determination for amp5 
the group issues notes in foreign currency under its emtn 
programme and uses cross currency swaps to convert the proceeds 
to sterling the effect of these swaps is that interest and principal 
payments on the borrowings are denominated in sterling and hence 
the currency risk is eliminated the foreign currency notes and the 
cross currency swaps are recorded in the balance sheet at their fair 
values and the changes in fair values are taken to gainslosses on  severn trent plc annual report and accounts 2011 25
business review
ﬁnancial instruments in the proﬁt and loss account since the terms 
of the swaps closely match those of the underlying notes such 
changes tend to be broadly equal and opposite
the group holds interest rate swaps with a net notional principal 
amount of £4623 million and cross currency swaps with a net 
notional principal amount of £5366 million which economically act 
to hedge the interest rate risk on ﬂoating rate debt or the exchange 
rate risk on certain foreign currency borrowings however the 
swaps do not meet the hedge accounting rules of ias 39 and 
therefore these swaps are carried in the balance sheet at fair value

severn trent’s policy is not to make any donations for political 
purposes in the uk or to donate to eu political parties or incur eu 
political expenditure accordingly neither severn trent plc nor its

expenditure in the ﬁnancial year under review
under the provisions of the political parties elections and 
referendums act 2000 the relevant provisions of which are now 
contained in part 14 of the companies act 2006 shareholder 
authority is required for political donations to be made or political 
expenditure to be incurred by the company or any of its subsidiaries 
in the eu and disclose any such payments in the annual report  
the legislation gives a wide deﬁnition of what constitutes political 
donations and political expenditure including sponsorship 
subscriptions payment of expenses paid leave for employees 
fulﬁlling public duties and support for bodies representing the 
business community in policy review or reform the company  
has therefore obtained limited authority from shareholders as a 
precautionary measure to allow the company to continue supporting 
the community and such organisations without inadvertently 
breaching the legislation
at the 2010 agm shareholders gave the company authorities to 
make political donations or to incur political expenditure in the eu 
which would not ordinarily be regarded as political donations up  
to an aggregate annual limit of £50000 for the company and its 
subsidiaries pursuant to those authorities during the year ended  
31 march 2011 the group incurred costs of £nil 2010 £nil those 
authorities will expire at the 2011 agm and in line with market 
practice to renew the authorities on an annual basis the board has 
decided to put forward a resolution to this year’s agm to renew the 
authorities to make donations to political organisations and to incur 
political expenditure up to a maximum of £50000 per annum  
as permitted under the companies act 2006 this resolution also 
covers any political donations made or political expenditure 
incurred by any subsidiaries of the company

operational and compliance and risk management at least annually 
in accordance with the requirements of the combined code for 
effectiveness and adequacy the internal control system can only 
provide reasonable and not absolute assurance against material 
misstatement or loss as it is designed to manage rather than 
eliminate the risk of failure to achieve business objectives
the audit committee reviews the group’s risk management process 
and the effectiveness of the system of internal control on behalf of

control and audit arrangements the audit committee receives 
reports every six months from the chief executive detailing the 
signiﬁcant risks and uncertainties faced by the group an 
assessment of the effectiveness of controls over each of those  
risks and an action plan to improve controls where this has been 
assessed as necessary during the course of its review of the 
system of internal control in 201011 the audit committee has not 
identiﬁed nor been advised of any failings or weaknesses which it 
has determined to be signiﬁcant therefore a conﬁrmation in respect 
of necessary actions has not been considered appropriate
the internal audit department provides objective assurance and 
advice on risk management and control the external auditor also 
reports on signiﬁcant ﬁnancial control issues to this committee
the board conﬁrms that procedures providing an ongoing process 
for identifying evaluating and managing the principal risks and 
uncertainties faced by the group have been in place for the year to 
31 march 2011 and up to the date of approval of the annual report 
which is in accordance with the revised guidance on internal control 
published in october 2005 the turnbull guidance

the group’s principal operating subsidiary severn trent water is a 
regulated long term business characterised by multi year investment 
programmes the group’s strategic funding objectives reﬂect this 
the group therefore seeks to attain a balance of long term funding 
or commitment of funds across a range of funding at the best 
possible economic cost average debt maturity is 16 years and the 
effective average interest cost during the year was 64 the group 
is in a strong liquidity position with £3152 million in cash and liquid 
reserves and £500 million of undrawn committed bank facilities 
which are expected to be sufﬁcient to fund its investment and cash 
ﬂow needs until march 2013 in the normal course of business 
severn trent water operates in an industry that is currently subject 
to economic regulation rather than market competition ofwat the 
economic regulator has a statutory obligation to set price limits that 
it believes will enable the water companies to ﬁnance their activities 
as a consequence the directors believe that the group is well placed 
to manage its business risks successfully despite the current 
uncertain economic outlook
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 they continue to adopt the going concern basis in 
preparing the annual report and accounts

dear shareholder
introduction
i want to set out in this letter how governance underpins our activities in severn trent and 
describe how we apply the principles of good corporate governance as set out in the 
combined code on corporate governance issued by the financial reporting council 
frc in 2008 combined code
compliance with the combined code
the combined code sets out standards of good practice that listed companies are 
expected to follow in areas such as how we structure the board appropriately and develop 
its members how we pay and reward our executive team our accountability and audit and 
our relationship with our shareholders 
for the whole of the ﬁnancial year ended 31 march 2011 severn trent was fully compliant  
in its application of the combined code 
our compliance with the combined code demonstrates our commitment to the highest 
standards of governance and corporate behaviour the combined code has been replaced 
during the ﬁnancial year by the uk corporate governance code the events in our 
corporate markets over the previous two years necessitated a review of the combined 
code and your board encouraged and supported the changes that the new code has 
introduced our response to the consultation on the review of the combined code is 
available for you to view on the website of the financial reporting council wwwfrcorguk 
the uk corporate governance code applies to accounting periods beginning on or after  
29 june 2010 our formal obligation for 2011 is to report how we have applied the principles 
of the combined code
board membership
from 10 may 2010 the board has consisted of me your nonexecutive chairman ﬁve

of the skills that they bring to bear can be found on pages 30 and 31 
further to the publication of the davis report ‘women on boards’ in february this year 
boards of ftse 350s have been encouraged to promote greater female representation  
on corporate boards recent guidance from the financial reporting council has also 
highlighted the importance of greater diversity of psychological proﬁle around the  
board table 
i consider that diversity in the board room is essential to good business helping companies 
better to meet the needs of their stakeholders
as part of our ongoing board membership renewal we will ensure that our recruitment and 
appointment processes continue to ensure that all appointments are meritocratic and that 
our board represents the best interests of shareholders

and accounting policies internal controls oversight of internal and external audit and the 
regulatory reporting obligations of our subsidiary severn trent water limited
financial statements and accounting policies
reviewing the ﬁnancial statements and accounting policies requires us to make certain 
judgements and we set out below some of the key issues we discussed in respect of 20101 1 
• the implementation of accounting standards in the period in particular ifric 18 in 
respect of assets transferred from customers 
• the assumptions which underpin accounting for the group’s retirement beneﬁts schemes
• the rationale for items shown as exceptional in the accounts
in reviewing the ﬁnancial statements we receive input from the executive disclosure 
committee and deloitte the former is chaired by the finance director and considers the 
content accuracy and tone of the ﬁnancial statements and other public disclosures prior  
to their release
deloitte reported to the committee on their review of the half year interim results and on 
their audit of the year end ﬁnancial statements
internal controls
we receive regular reports from internal audit in respect of their work on internal controls 
and we review management letters received from the external auditors we review internal 
audit’s annual review of fraud prevention and mitigation as well as a regular fraud log
technology controls and governance were areas of focus in 201011 and we received 
several reports on the control environment in this area where we had previously identiﬁed 
the potential to enhance controls much progress has been made in improving the control 
environment and we will continue to monitor progress into 201112
we reviewed the processes for and outputs from our enterprise risk management process 
through which the principal risks and related controls are identiﬁed in addition we

certiﬁcation in respect of the accounting records and processes which underpin the 
calculation of tax liabilities for uk based companies owned by the group

requirements to ofwat and these are also covered by the audit committee these 
regulatory reporting obligations include a comprehensive annual return on all of severn 
trent water limited’s regulatory obligations known as the june return and a statement 
that underpins the customer charges made by severn trent water limited known as the

reporter on their work as part of its review of the returns
in june 2010 we held an additional meeting to consider and review the new ofwat reporting

to operate effectively 
policy on the provision of nonaudit 
services
the company has approved a formal 
policy on the provision of nonaudit 
services aimed at safeguarding and 
supporting the independence and 
objectivity of the external auditor
the policy sets out the approach to be 
taken by the group when using the 
services of the external auditor including 
requiring that certain services provided 
by the external auditor are preapproved 
by the audit committee or its chairman 
it distinguishes between those services 
where an independent view is required 
and that should be performed by the 
external auditor such as statutory and 
nonstatutory audit and assurance work 
prohibited services where the 
independence of the external auditor 
could be threatened and they must not 
be used and other nonaudit services 
where the external auditor may be used 
nonaudit services where the external 
auditor may be used include non
recurring internal controls and risk 
management reviews ie excluding 
outsourcing of internal audit work advice 
on financial reporting and regulatory 
matters due diligence on acquisitions 
and disposals project assurance and 
advice tax compliance services and 
employee tax services 
the approval of the audit committee  
or its chairman is always required if  
a nonaudit service provided by the 
auditor is expected to cost more than 
£100000 or if nonaudit fees for the  
year would thereby exceed the amount  
of the audit fee severn trent plc annual report and accounts 2011 42

corporate responsibility committee
the purpose of the corporate responsibility cr committee is to provide board oversight 
of the management of all nonﬁnancial risks to the group the structure for our cr policy 
and framework is based around the four areas of workplace marketplace environment  
and community providing a common framework for both our businesses – regulated and 
nonregulated the framework remains under review as we continue to integrate corporate 
responsibility into our core business operations for both severn trent water and severn 
trent services for each of the areas there are four goals within our cr policy which help 
to focus improvements in our performance
within our cr framework we have identiﬁed 10 focus areas that are critical to our 
management of risk and reputation these areas have been determined through 
stakeholder dialogue risk assessment and benchmarking within the water industry and the 
ftse 100 the 10 areas provide the focus of the forward agenda of our cr committee
workplace
health safety and wellbeing employee skills conduct and motivation diversity
marketplace
customer needs – including vulnerable customers supply chain responsibility
environment
environmental stewardship waste reduction and recycling climate change – 
mitigation and adaptation
community
community engagement working with our customers – including pollution 
prevention and water efﬁciency

through 18 core business key performance indicators kpis and eight ksis these are 
overseen by the severn trent executive committee and the board many of the business 
kpis relate directly to our cr focus areas and therefore contribute signiﬁcantly to our cr

remuneration committee
this report sets out the remuneration policy for the directors of severn trent plc and 
discloses the amounts paid to them in the year ended 31 march 2011
the report is subject to a shareholder vote and a resolution to approve this directors’ 
remuneration report will be proposed at the agm the report has been prepared in 
accordance with the requirements of the companies act 2006 the principles of the 
combined code on corporate governance and best practice guidelines
during the year the committee undertook a thorough review of the variable arrangements 
for the executive directors and other members of the severn trent executive committee 
this review included an examination of both the quantum and structure of the variable pay 
arrangements and the measures used to assess performance the conclusions of this 
review were as follows
• the committee determined that the structure of awards cash bonus deferred share 
bonus with matching and long term incentive plan awards remained appropriate and the 
signiﬁcant proportion of variable pay delivered in shares provided a strong alignment 
between the interests of management and shareholders
• the quantum of rewards remains competitive and no changes were proposed to current 
award levels
• the performance measures and weighting of the targets for the annual bonus plan 
severn trent water kpis personal performance and severn trent services performance 
for the chief executive and finance director continue to provide a strong and challenging 
assessment of the ﬁnancial and operating performance of the business the annual 
bonus will therefore continue to operate on the same basis for 201112 save that severn 
trent water performance will be measured by reference to 20 rather than 18 kpis
• relative tsr remains an appropriate measure of performance for the share matching 
plan providing alignment with the returns received by shareholders in the absence of a 
sufﬁcient number of listed utility companies the current ftse 51150 comparator group  
is considered the most relevant benchmark for measuring performance however to 
address the share price volatility caused by the uncertainty of the ﬁve year pricing review 
rather than measuring performance over a single three year period a multipoint 
measurement basis will be applied to future grants 20 over 018 months 30 over 
027 months and 50 over 036 months the awards will continue to be subject to the 
committee being satisﬁed with the ﬁnancial performance over the performance period 
and further there being no compromise to the commercial integrity of severn trent over 
the performance period this approach should reduce the impact of price uncertainty in 
the run up to new asset management periods and reward for sustainable and steady 
shareholder returns
• to provide a stronger focus on the long term ﬁnancial performance of the business  
future awards under the long term incentive plan ltip will be subject to a performance 
measure based on the company’s return on regulatory capital value rorcv compared 
to the ofwat final determination current awards under this plan are subject to a relative 
tsr performance condition rorcv was chosen as the measure of performance 
because it directly targets management’s delivery of the business plan for awards 
granted in 2011 0 of the shares will vest if rorcv equals the final determination 
increasing on a straight line basis to 50 vesting if rorcv exceeds the final 
determination by 2 pa and 100 vesting for outperformance of 7 pa or more 
performance will be based on the average rorcv over three ﬁnancial years starting in 
the year in which the award is granted further details on the performance measure for 
the 2011 award are set out on page 48
the committee believes that the new performance measures for the share matching plan 
and long term incentive plan will provide a more rounded assessment of the overall 
ﬁnancial and operational performance of the business and will provide a clearer line of sight 
for executives between performance and reward

remuneration policy
each year the committee reviews the remuneration policy for 
executive directors and other senior executive managers taking  
into account both the external market and the company’s strategic 
objectives over the short and the medium term 
the company’s continuing remuneration policy for executive 
directors is to provide remuneration in a form and amount which  
will attract retain motivate and reward high calibre individuals  
the remuneration package is based on the following principles
principle rationale
incentives are aligned with the 
interests of shareholders and 
seek to reward the creation of 
long term value 
executives must be adequately 
focused on the long term 
strategy and make decisions 
that lead to the creation of long 
term value
reward elements are designed 
to reinforce the link between 
performance and reward 
performance related elements 
should form a significant 
proportion of the total 
remuneration package and 
typically comprise at least 50 
of total remuneration if paid at 
the maximum
the performance of the 
business is key and the  
package should be 
appropriately geared towards 
performance related pay 
the total remuneration package 
for on target performance 
should be fully competitive but 
not excessive in the relevant 
market 
the committee wishes the 
executives to be appropriately 
remunerated for the challenges 
they face and ensure that the 
right structure and levels are  
in place to take the business 
forward
packages are structured flexibly 
to meet critical resource needs 
and retain key executives 
package flexibility allows the 
committee to take decisive 
action with issues of recruitment 
and retention in the best 
interests of business continuity 
and shareholder value severn trent plc annual report and accounts 2011 45
governance
the charts below show as a proportion of the package ﬁrstly the 
expected values of salary bonus and long term incentives for target 
performance and secondly the maximum values of salary bonus 
and long term incentives for the executive directors based on the 
proposed remuneration policy for 201112 the committee

the committee takes seriously the issue of balancing risk and 
reward during the year the committee undertook a detailed review 
of the variable pay arrangements for the executive directors and 
other members of the executive committee the committee 
concluded that the schemes were appropriately managed and the 
choice of performance measures and targets did not encourage 
undue risk taking by the executives the schemes incorporate a 
range of internal and external performance metrics measuring both 
operational and ﬁnancial performance providing a rounded 
assessment of overall company performance the committee 
retains ultimate approval for the executive incentive schemes and all 
share plans across the company and has the ﬁnal discretion as to 
how they are applied furthermore the rules of the annual bonus 
scheme and long term incentive schemes provide that the 
committee may reclaim ‘clawback’ some or all of the after tax part 
of any award to executive directors if it transpires that the award was 
based on calculations which are subsequently demonstrated to be 
materially incorrect
personal shareholdings 
the company operates shareholding guidelines under which 
executive directors are expected to build and maintain a minimum 
holding of shares in the company the chief executive is expected  
to build and maintain a holding of shares to the value of 15 x base 
salary and other executive directors 1 x base salary executive 
directors are expected to retain at least half of the shares they 
receive through the long term incentive plan and other share based 
plans until they meet the guideline holdings details of the current 
shareholdings of the executive directors are set out on page 52
external directorships
executive directors are permitted to take on external nonexecutive 
directorships though normally only one other ftse 100 
appointment in order to avoid any conﬂicts of interest all such 
appointments are subject to the approval of the nominations 
committee executive directors are normally only permitted to retain 
the fees arising from one such appointment
michael mckeon was appointed as a nonexecutive director of  
the merchants trust plc on 1 may 2008 and in respect of the 
appointment for the year ended 31 march 2011 he was paid fees  
of £20115 he has retained these fees in accordance with the 
above policy
no other executive directors currently hold any external fee earning 
nonexecutive directorships
base salaries and beneﬁts
base salaries for individual directors are reviewed annually by  
the committee and take effect from 1 july salaries are set with 
reference to individual performance experience and contribution 
together with developments in the relevant employment market 
having regard to the market median for similar roles in publicly 
quoted companies of a comparable size and practice in other  
water companies and internal relativities
the committee gives due consideration to the current economic 
climate and current market practice regarding executive salary 
reviews and the broader employee salary review policy at the 
company the committee has not set a speciﬁc policy on the 
relationship between executive directors’ pay and that of the rest  
of the workforce but aims to pay all employees fairly taking into 
account their respective roles and responsibilities
with this in mind the committee adopted a policy of a zero increase 
for the base salaries of the executive directors in 200910 and a 2 
increase in 201011 against a backdrop of economic recovery it 
has chosen to adopt a general policy of 3 increase for the base 
salaries of the executive directors in 201112 this is in line with the 
policy of all employees of a 3 increase for base salaries
at the time of the chief executive’s appointment his salary reﬂected 
the fact that he was new to the role and accordingly the committee 
gave a commitment to review his performance each year and if 
appropriate increase the base salary over time to align it with the 
market median the committee agreed that the chief executive’s 
base salary should be reviewed again this year giving due 
consideration to the performance of the company and the  
individual and the internal relativity with the other executive  
directors and market alignment the committee agreed that the 
chief executive’s base salary will be increased from £500000  
to £550000 on 1 july 2011 
the nonsalary beneﬁts for executive directors comprise
• a car allowance
• private medical insurance
• life assurance
• an incapacity beneﬁts scheme

the bonus outturn in respect of severn trent water performance 
was operated by reference to a balanced scorecard of measures 
based on the 18 kpis the committee believes that the use of the 
severn trent water kpis continues to be both an effective and 
challenging annual bonus metric and meets the needs of the 
business the bonus entitlement was determined by reference to 
the aggregate number of points awarded across all the kpis the 
targets taken together are considered by the board to have an 
impact on the longer term ﬁnancial performance of the company 
and a number of them are reported to ofwat 
the table below shows the points awarded by the committee for 
bonus purposes under each of the 18 kpis in relation to the 201011 
annual bonus scheme four of the 18 kpi points have been 
adjusted upwards this was only done after detailed consideration 
and in making this decision we recognised that management had 
done the right thing when faced with exceptional operational 
challenges over the winter period they also maintained overall 
ﬁnancial performance as a consequence the bonus awarded for 
the severn trent water portion of the annual bonus was 400 of its 
bonus element maximum
the chief executive and finance director have 10 of their bonus 
linked to the performance of severn trent services performance  
is measured against the proﬁt before interest and tax before 
exceptional items of severn trent services a measure which is a 
fully disclosed kpi of the severn trent services business as shown 
in the business review section performance is measured against 
budgeted proﬁt reﬂecting the desired growth of severn trent 
services subject to adjustment by the committee based on its 
assessment of overall performance of the business severn trent 
services performance over the year did not reach its target and 
therefore resulted in a bonus award of 0
in addition each director has 10 of their bonus opportunity 
measured against a set of personal performance metrics  
the metrics for 201011 include
• supporting the business change and transformation process 
– focusing on the ongoing improvements to optimise the 
performance of the business eg process improvements 
technology and systems to support the processes and location 
training and development of people to operate in the new 
environment and
• developing people – focusing on the individual’s contribution to 
ensuring that the talent management processes help to develop 
future leaders and therefore support succession planning and 
business continuity
half of any bonus paid is deferred into shares to be held for three 
years following payment if the executive is summarily dismissed 
without notice under hisher employment contract then the deferred 
bonuses are forfeited in all other cases of cessation of employment 
the deferred bonus is not lost and the shares automatically vest on 
the dealing day after the cessation of employment
the rules of the annual bonus scheme provide that the committee 
may reclaim ‘clawback’ some or all of the after tax part of any 
bonuses awarded to executive directors if it transpires that the 
bonus calculation was based on calculations which are 
subsequently demonstrated to be materially incorrect
for the purpose of the annual bonus calculation kpis – ofwat efﬁciency billing factor and capex process quality are not included severn trent plc annual report and accounts 2011 48
governance
remuneration committee continued
annual bonus payments to executive directors are not pensionable
the committee has reviewed the operation of the plan and 
concluded that it should operate on the same basis for 201112 
however for 201112 severn trent water performance will be 
measured by reference to 20 kpis as set out on page 47 
long term incentives
as disclosed on page 43 the committee undertook a thorough 
review of the incentive arrangements during the year and determined 
that some changes should be made to the operation of the long term 
incentive schemes to encourage a greater focus on operational 
performance and to provide a fairer method of assessing 
performance in this section we set out details of both the long term 
incentives in place for the year under review and the proposed long 
term incentive arrangements for 201112 and beyond
during the year under review the executive directors participated in 
two long term incentive schemes i a long term incentive plan 
and ii a share matching plan
a long t erm incentive plan
the long term incentive plan ltip was approved by shareholders 
at the 2005 agm under the ltip  annual conditional awards of 
performance shares may be made to executive directors and senior 
staff up to an annual maximum limit of shares worth 125 of base 
salary in 2010 a share award equivalent to 70 of salary was 
made to the chief executive and 50 of salary to the other 
executive directors
the number of shares subject to an award will be increased to 
reﬂect dividends paid through the performance period on the basis 
of such notional dividends being reinvested at the then prevailing 
share price awards will normally vest as soon as the committee 
determines that the performance conditions have been met 
provided that the participant remains in employment at the end  
of the performance period
vesting of awards granted under the ltip since 2006 has been 
subject to tsr performance measured relative to those companies 
ranked 51–150 in the ftse by market capitalisation excluding 
investment trusts 25 of awards vesting at median performance 
and 100 vesting for performance in the upper quartile in addition 
for awards to vest the committee must be satisﬁed that the 
company’s tsr is reﬂective of the company’s underlying 
performance this is the same performance condition as applying  
to the awards granted in 2010 under the share matching plan
at the end of the performance period for each award the tsr 
performance condition will be measured and independently veriﬁed 
by hewitt new bridge street on behalf of the committee
as disclosed on page 43 of this report during the year the 
committee undertook a review of the variable pay arrangements for 
executives and determined to change to the performance targets 
applying to future ltip awards to provide a stronger alignment 
between the long term ﬁnancial and operational performance of the 
group and the rewards delivered to management
vesting of awards granted in 2011 and beyond will be based on 
return on regulatory capital value rorcv with a sliding scale of 
targets linked to outperformance of the ofwat final determination 
the targets for awards granted in 2011 will be as follows 
severn trent average annual 
rorcv outperformance against  
the ofwat final determination 
expectation
vesting level for performance 
shares
less than or equal to final 
determination ≤100
0
102 50
107 or higher 100
performance will be measured over the three ﬁnancial years ending 
31 march 2012 2013 and 2014 the committee reserves the 
discretionary power to change the result if it is 0 or greater than 
50 if it is greater than 50 it can reduce the vesting to not less 
than 50 if it is 0 it can increase the vesting to not more than 
50 the use of this discretion is expected to be exceptional but 
may be invoked by the committee in order to take into account of 
any of the following factors not an exhaustive list
• actual rpi compared to the ofwat assumed rpi ﬁgure – even 
though the regulatory capital value is adjusted each year for rpi  
a signiﬁcant swing in inﬂation during the year can result in 
substantial under or over performance on the return on regulatory 
capital value target
• changes to the ﬁnancing of the company as approved by the 
board during the performance period – for example a signiﬁcant 
change to the level of gearing of the balance sheet would result  
in partially meeting this performance condition
• policy changes that occur during the performance period – there 
is much discussion on the future shape of the water industry in  
the uk and if enacted we would wish to ensure that any changes 
have a neutral impact on existing awards
b share matching plan
under the share matching plan executives can receive up to one 
matching share for each share deferred under the annual bonus 
plan for awards made in 2010 the ﬁrst set of awards granted under 
the plan the ratio was limited to 05 matching share for each 
deferred share the performance condition requires the company’s 
tsr to be measured relative to those companies ranked 51–150  
in the ftse index by market capitalisation excluding investment 
trusts this is considered to be the most suitable comparator group 
since the number of comparable regulated utilities against which to 
compare the company’s performance remains too small to enable 
meaningful analysis the ftse 51–150 comparator group allows for 
the company’s performance to be measured against a broader 
market without any one sector overly impacting the group 25 of 
the matching awards will vest at median performance and 100 will 
vest for performance in the upper quartile in addition for awards to 
vest the committee must be satisﬁed that the tsr is reﬂective of 
the company’s underlying performance this replicates the ltip 
performance condition for the 2010 awards
as with the ltip  the number of shares subject to an award will be 
increased to reﬂect dividends paid through the performance period 
on the basis of such notional dividends being reinvested at the then 
prevailing share price awards will normally vest as soon as the 
committee determines that the performance conditions have been 
met provided that the participant remains in employment at the end 
of the performance period severn trent plc annual report and accounts 2011 49
governance
after careful review the committee concluded that relative tsr 
remains the most appropriate performance measure for the share 
matching plan since it provides alignment between the rewards 
received by management and the returns received by shareholders 
the ftse 51150 comparator group will be retained and the same 
vesting schedule will apply 25 vesting at median performance 
increasing on a straight line basis to 100 vesting for performance 
in the upper quartile however rather than measure performance 
over a single three year period the committee concluded that for 
future awards performance would be measured on a multipoint 
basis 20 over 018 months 30 over 027 months and 50 over 
036 months the awards will continue to be subject to the 
committee being satisﬁed with the ﬁnancial performance over the 
performance period and further there being no compromise to the 
commercial integrity of severn trent over the performance period
the committee has the authority to reclaim ‘clawback’ some or all 
of the after tax part of any shares awarded to executive directors 
under the long term incentive plan and share matching plan and  
if it transpires that the vesting calculation was based on calculations 
which are subsequently demonstrated to be materially incorrect

through a variety of share schemes employees are encouraged  
to hold shares in the company
this includes an all employee share incentive plan awards are 
currently made which include a performance condition based on  
the award of points for the kpis employees of severn trent plc and 
severn trent water limited participate in the plan for the year 
201011 awards of shares to the value of £300 will be made to all 
eligible employees
the company also offers an all employee hmrc approved saye 
plan on an annual basis and periodically reviews the use of other  
all employee incentive vehicles
hedging of awards
details of the company’s shares that are held in trust on behalf of 
participants of certain of the employee share schemes are given on 
pages 53 and 54 in respect of the ltips deferred share awards 
under the annual bonus scheme and the share matching plan the 
company’s policy is to purchase and hold in trust 50 of the total 
number of shares that could potentially vest from all outstanding 
awards the requirement to purchase shares is calculated and the 
purchase carried out shortly after each annual award
in respect of awards made under the company’s share incentive 
plan all the shares taken up by employees at each invitation are 
normally purchased and placed in trust immediately
the company grants saye options over unissued shares always 
operating within the dilution limits contained in the scheme rules
the committee is satisﬁed that the overall dilution limits provide 
sufﬁcient headroom for all the company’s share schemes
pensions
severn trent executives receive retirement beneﬁts from a variety 
of pensions arrangements including deﬁned beneﬁt deﬁned 
contribution payments made direct to personal plans and cash  
in lieu as a result of the changes in pension legislation for high 
earners severn trent will introduce the following options from april 
2011 for any individuals who are affected by the tax changes
for defined contribution members
• continue in the scheme and meet any tax liabilities as they fall 
due or
• continue in the scheme up to the annual allowance £50000 for 
201112 tax year and receive a cash alternative equivalent to the 
level of employer contributions made to the scheme above the 
annual allowance 
for defined benefit members 
• continue in the scheme and meet any tax liabilities as they fall due
• opt out of future deﬁned beneﬁt accrual and join the deﬁned 
contribution section with the same options as above
of the current executive directors andy smith and tony wray 
participate in the severn trent pension scheme the scheme is a 
funded hmrc registered ﬁnal salary occupational pension scheme 
which provides severn trent plc annual report and accounts 2011 50

remuneration committee continued
•  a normal retirement age of 60 years
• an overall pension at normal retirement age of two thirds of ﬁnal 
pensionable salary which for executive directors is deﬁned as 
base salary only subject to the completion of 20 years’ 
pensionable service
• life cover of 4 x pensionable earnings
• a pension payable in the event of retirement on grounds of ill 
health and
• a dependant’s pension on death of two thirds of the member’s 
pension
andy smith and tony wray participate up to the level of the scheme 
speciﬁc earnings cap which in 201011 was £129600 they are 
provided with a cash supplement in lieu of pension entitlement 
above this scheme cap at 40 of their respective salaries
members’ contributions are payable at the rate of 6 of pensionable 
earnings early retirement is available after the age of 55 with the 
consent of the company any pension would be subject to a 
reduction that the trustees consider appropriate acting on actuarial 
advice to reﬂect the expected longer payment of the pension in the 
event of incapacity early retirement is available on an unreduced 
basis allowing for pensionable service to age 60
under the trust deed and rules pension payments in excess of 
any guaranteed minimum pension are guaranteed to increase in 
line with price inﬂation subject to a maximum of 5 each year in the 
calculation of individual cash equivalent transfer values allowance is 
made for such increases
it is the policy of the committee to offer new executives an 
allowance expressed as a percentage of base salary to fund their 
own pension provision the individual is able to choose whether the 
allowance is paid to the company’s registered deﬁned contribution 
scheme taken as cash or paid to a personal pension arrangement 
this reﬂects the wish of the committee to remove future exposure to 
deﬁned beneﬁt schemes for senior executives these arrangements 
apply to michael mckeon at 40 of base salary
martin kane is a member of the severn trent pension scheme 
wps section but opted out of the scheme in june 2007  he 
receives a cash supplement of 30 of his basic salary in lieu of 
accrual for future service from that date while he no longer accrues 
additional years of service for pension purposes consistent with the 
legislation martin kane’s accrued beneﬁts generally continue to be 
linked to his ﬁnal salary or £161000 plus rpi from 30 june 2007  
to the date of his retirement if higher and scheme beneﬁts are 
preserved in relation to ill health retirement and death in service 
the normal retirement age for the scheme is 65 although early 
retirement is possible prior to age 65 with the consent of the 
company but any beneﬁts relating to service accruing after 
1 december 2006 would be subject to an actuarial reduction
tony ballance is a member of the severn trent pension scheme

scheme is 65 although retirement prior to 65 is possible with the 
consent of the company

the committee believes that the contracts provide as much scope 
as is feasible to protect the interests of shareholders when 
negotiating a termination at which time it would address the duty  
of mitigation
the committee recognises that in line with current best practice 
guidelines any termination payment should be based upon an 
estimate of salary and ﬁxed beneﬁts only accordingly the 
committee will adopt this policy in the service agreements of future 
executive directors
in accordance with the uk corporate governance code all the 
directors are subject to reappointment as directors at the

notes 
relevant directors conﬁrmed by severn trent plc
accrued pension ﬁgures and transfer value calculations provided by towers watson
there have been no changes to the transfer value basis since last year’s disclosures
allowance has been made for changes in market conditions over the year by applying the relevant market value adjustment
inﬂation ﬁgure used in respect of year is to february 2011 55 as the latest available ﬁgure prior to the year end
1 martin kane has an increase in accrued pension from £121236 to £126829 equating to 46 inﬂation level used february 2011 is 55 producing a negative net of inﬂation 
ﬁgure therefore the beneﬁt increase is due to a change in salary not from additional accrual earned over the reporting period

enterprise risk management
our established enterprise risk management erm process as 
illustrated above is used for the identiﬁcation and assessment of 
risks to signiﬁcant business objectives this includes consideration 
of the effectiveness of existing controls and identiﬁcation 
prioritisation and tracking of actions needed to reduce the risk and
or improve controls our assessment also considers both ﬁnancial 
and reputational impact of risks in order to give a holistic view
during the year we have continued to work to fully embed the 
process across the business including rolling out the process to 
severn trent services we have continued to keep the process 
fresh through the introduction of new tools and challenges and are 
working to better integrate with the processes used by business 
teams to monitor their performance
the key business risks are formally reported to the severn trent 
executive committee and audit committee every six months and  
to the board annually reviews of risk generally take place within  
the business on a quarterly basis to monitor that our key risks are 
identiﬁed that controls and mitigating actions continue to be 
effective and to conﬁrm that focus is maintained on the most critical 
risks requiring attention
during the year we have also held a risk workshop with the board 
which looked at their views on the most signiﬁcant risks facing the 
organisation in order to give greater visibility of their view on risk 
the key focus of these discussions was around the inter
relationships between risks and the board recognised that whilst 
some risks may not be catastrophic on their own an aggregation of 
smaller risks occurring simultaneously or in close succession could 
become very signiﬁcant
in response to the discussions at the board we are now conducting 
a series of workshops aimed at challenging the robustness of 
controls in order to help us withstand even the most catastrophic 
scenario these workshops will consider the interrelationships 
between risks to enable us to obtain maximum value from the risk 
information held
over the coming year we will continue to work to maintain and 
improve our erm process with a particular emphasis on closer 
integration with the business planning process this will include 
clearer articulation of our willingness to accept risk as part of the 
prioritisation of business activity  severn trent plc annual report and accounts 2011 57

financial statements
notes to the group financial statements
for the year ended 31 march 2011
1 general information
the severn trent group has a number of operations these are 
described in the segmental analysis in note 5
severn trent plc is a company incorporated and domiciled in the 
united kingdom the address of its registered office is shown on 
the back of the cover of the annual report and accounts
severn trent plc is listed on the london stock exchange
2 accounting policies
a basis of preparation
the financial statements have been prepared in accordance  
with international financial reporting standards ifrs 
international accounting standards ias and ifric 
interpretations issued and effective and ratified by the  
european union as at 31 march 2011
the financial statements have been prepared on the going 
concern basis see directors’ report on page 28 under the 
historical cost convention as modified by the revaluation of 
certain financial assets and liabilities including derivative 
instruments at fair value
the preparation of financial statements in conformity with ifrs 
requires the use of estimates and assumptions that affect the 
reported amounts of assets and liabilities at the date of the 
financial statements and the reported amount of revenues and 
expenses for the reporting period although these estimates are 
based on management’s best knowledge of the amount event or 
actions actual results may ultimately differ from those estimates
b  basis of consolidation
the financial statements include the results of severn trent plc 
and its subsidiaries joint ventures and associated undertakings 
the results of subsidiaries joint ventures and associated 
undertakings are included from the date of acquisition or 
incorporation and excluded from the date of disposal
the results of subsidiaries are consolidated where the group has 
the power to control a subsidiary
the results of joint venture undertakings are accounted for on an 
equity basis where the company exercised joint control under a 
contractual arrangement
the results of associates are accounted for on an equity basis 
where the company holding is 20 or more or the company has 
the power to exercise significant influence
noncontrolling interests in the net assets of consolidated 
subsidiaries are identified separately from the group’s equity 
therein noncontrolling interests consist of the amount of those 
interests at the date of the original business combination and the 
noncontrolling interest’s share of changes in equity since that 
date losses attributable to the noncontrolling interest in excess 
of its interest in the subsidiary’s equity are allocated against the 
interests of the group except to the extent that the non
controlling interest has a binding obligation and is able to make 
an additional investment to cover the losses
all intragroup transactions balances income and expenses are 
eliminated on consolidation
c revenue recognition
revenue represents the fair value of consideration receivable 
excluding value added tax trade discounts and intercompany 
sales in the ordinary course of business for goods and  
services provided
revenue is not recognised until the service has been provided to 
the customer or the goods to which the sale relates have either 
been despatched to the customer or where they are held on the 
customer’s behalf title has passed to the customer
turnover includes an estimate of the amount of mains water and 
waste water charges unbilled at the year end the accrual is 
estimated using a defined methodology based upon a measure 
of unbilled water consumed by tariff which is calculated from 
historical billing information
in respect of long term contracts revenue is recognised based 
on the value of work carried out during the year with reference  
to the total sales value and the stage of completion of  
these contracts
interest income is accrued on a time basis by reference to the 
principal outstanding and at the effective interest rate applicable 
dividend income from investments is recognised when the 
group’s rights to receive payment have been established 
interest and dividend income are included in finance income
d exceptional items
exceptional items are income or expenditure which individually 
or if of a similar type in aggregate should in the opinion of the 
directors be disclosed by virtue of their size or nature if the 
financial statements are to give a true and fair view in this 
context materiality is assessed at the segment level
e taxation
current tax payable is based on taxable profit for the year 
taxable profit differs from net profit as reported in the income 
statement because it excludes items of income and expenses 
that are taxable or deductible in other years and it further 
excludes items that are never taxable or deductible the  
group’s liability for current tax is calculated using tax rates  
that have been enacted or substantively enacted by the  
balance sheet date
deferred taxation is provided in full using the liability method  
on taxable temporary differences between the tax bases of 
assets and liabilities and their carrying amounts in the financial 
statements a deferred tax asset is only recognised to the extent 
it is probable that sufficient taxable profits will be available in  
the future to utilise it deferred taxation is measured on a 
nondiscounted basis using the tax rates and laws that have  
then been enacted or substantively enacted by the balance 
sheet date and are expected to apply when the related deferred 
income tax asset is realised or the deferred tax liability is settled 
deferred tax assets and liabilities are offset when there is a 
legally enforceable right to set off current tax assets against 
current tax liabilities and when they relate to income taxes  
levied by the same taxation authority and the group intends  
to settle its current tax assets and liabilities on a net basis
f goodwill
goodwill represents the excess of the fair value of purchase 
consideration over the fair value of the net assets acquired 
goodwill arising on acquisition of subsidiaries is included in 
intangible assets whilst goodwill arising on acquisition of 
associates is included in investments in associates if an 
acquisition gives rise to negative goodwill this is credited  
directly to the income statement fair value adjustments  
based on provisional estimates are amended within one year  
of the acquisition if required with a corresponding adjustment  
to goodwill severn trent plc annual report and accounts 2011 66

goodwill arising on all acquisitions prior to 1 april 1998 was 
written off to reserves under uk gaap and remains eliminated 
against reserves purchased goodwill arising on acquisitions 
after 31 march 1998 is treated as an intangible fixed asset
goodwill is tested for impairment in accordance with the policy 
set out in note 2 m below and carried at cost less accumulated 
impairment losses goodwill is allocated to the cashgenerating 
unit that derives benefit from the goodwill for impairment  
testing purposes
where goodwill forms part of a cashgenerating unit and all  
or part of that unit is disposed of the associated goodwill is 
included in the carrying amount of that operation when 
determining the gain or loss on disposal of the operation
g intangible noncurrent assets
intangible assets acquired separately are capitalised at cost and 
when acquired in a business combination are capitalised at fair 
value at the date of acquisition following initial recognition the 
historical cost model is applied to intangible assets amortisation 
charged on assets with finite lives is taken to the income 
statement through operating expenses
finite life intangible assets are amortised on a straight line basis 
over their estimated useful economic lives as follows
intangible assets are reviewed for impairment where indicators 
of impairment exist
h research and development
research expenditure is expensed when it is incurred 
development expenditure is capitalised and written off over  
its expected useful economic life where the following criteria  
are met
• it is technically feasible to create and make the asset 
available for use or sale 
• there are adequate resources available to complete the 
development and to use or sell the asset
• there is the intention and ability to use or sell the asset
• it is probable that the asset created will generate future 
economic benefits and
• the development cost can be measured reliably
expenditure on property plant and equipment relating to 
research and development projects is capitalised and written  
off over the expected useful life of those assets
i precontract costs
precontract costs are expensed as incurred except where it is 
probable that the contract will be awarded in which case they 
are recognised as a prepayment which is written off to the 
income statement over the life of the contract
j property plant and equipment
property plant and equipment is held at cost or at deemed 
costs for infrastructure assets on transition to ifrs less 
accumulated depreciation the costs of like for like replacement 
of infrastructure components are recognised in the income 
statement as they arise where it is probable that the 
expenditure will cause future economic benefits to flow to  
the group then costs are capitalised 
where items of property plant and equipment are transferred  
to the group from customers or developers the fair value of the 
asset transferred is recognised in the balance sheet fair value 
is determined based on estimated depreciated replacement cost 
where the transfer is in exchange for connection to the network 
and there is no further obligation the corresponding credit is 
recognised immediately in turnover where the transfer is 
considered to be linked to the provision of ongoing services  
the corresponding credit is recorded in deferred income and 
released to operating costs over the expected useful lives of  
the related assets
borrowing costs directly attributable to the acquisition 
construction or production of assets that necessarily take a 
substantial period of time to get ready for their intended use are 
added to the cost of those assets until such time as the assets 
are ready for their intended use
property plant and equipment is depreciated to its estimated 
residual value over its estimated useful life with the exception  
of freehold land which is not depreciated assets in the course  
of construction are not depreciated until commissioned
the estimated useful lives are
k leased assets
where the group obtains assets under leasing arrangements 
which transfer substantially all the risks and rewards of 
ownership of an asset to the group as lessee finance leases 
the lower of the fair value of the leased asset or the present 
value of the minimum lease payments is capitalised as an asset 
with a corresponding liability representing the obligation to the 
lessor lease payments are treated as consisting of a capital 
element and a finance charge the capital element reducing the 
obligation to the lessor and the finance charge being written off 
to the income statement at a constant rate over the period of  
the lease in proportion to the capital amount outstanding 
depreciation is charged over the shorter of the estimated useful 
life and the lease period
leases where substantially all the risks and rewards of 
ownership remain with the lessor are classified as operating 
leases rental costs arising under operating leases are 
expensed on a straight line basis over the term of the lease 
leases of land are normally treated as operating leases unless 
ownership is transferred to the group at the end of the lease
l grants and contributions
grants and contributions received in respect of noncurrent 
assets including certain charges made as a result of new 
connections to the water and sewerage networks are treated as 
deferred income and released to the income statement over the 
useful economic life of those noncurrent assets
2 accounting policies continued
f goodwill continued severn trent plc annual report and accounts 2011 67
financial statements
grants and contributions which are given in compensation for 
expenses incurred with no future related costs are recognised in 
operating costs in the income statement in the period that they 
become receivable
m impairment of noncurrent assets
if the recoverable amount of goodwill an item of property plant 
and equipment or any other noncurrent asset is estimated to be 
less than its carrying amount the carrying amount of the asset  
is reduced to its recoverable amount where the asset does not 
generate cash flows that are independent from other assets the 
group estimates the recoverable amount of the cashgenerating 
unit to which the asset belongs recoverable amount is the 
higher of fair value less costs to sell or estimated value in use  
at the date the impairment review is undertaken fair value less 
costs to sell represents the amount obtainable from the sale  
of the asset in an arm’s length transaction between 
knowledgeable and willing third parties less costs of disposal 
value in use represents the present value of future cash flows 
expected to be derived from a cash generating unit discounted 
using a pretax discount rate that reflects current market 
assessments of the cost of capital of the cashgenerating  
unit or asset
the discount rate used is based on the group’s cost of capital 
adjusted for the risk profiles of individual businesses
goodwill is tested for impairment annually impairment reviews 
are also carried out if there is an indication that an impairment 
may have occurred or where otherwise required to ensure  
that noncurrent assets are not carried above their estimated 
recoverable amounts
impairments are recognised in the income statement
n inventory
inventory and work in progress is stated at the lower of cost and 
net realisable value cost includes labour materials transport 
and attributable overheads
o service concession agreements
where the group has an unconditional right to receive cash from 
a government body in exchange for constructing or upgrading  
a public sector asset the amounts receivable are recognised  
as a financial asset in prepayments and accrued income
costs of constructing or upgrading the public sector asset are 
recognised on a straight line basis before adjusting for expected 
inflation over the life of the contract
p retirement benefits
the group operates both defined benefit and defined 
contribution pension schemes
the difference between the value of defined benefit pension 
scheme assets and defined benefit pension scheme liabilities  
is recorded on the balance sheet as a retirement benefit asset  
or obligation
defined benefit pension scheme assets are measured using bid 
price defined benefit pension scheme liabilities are measured  
at the balance sheet date by an independent actuary using the 
projected unit method and discounted at the current rate of 
return on high quality corporate bonds of equivalent term and 
currency to the liability service cost which is the increase in the 
present value of the liabilities of the group’s defined benefit 
pension schemes expected to arise from employee service in 
the period is included in operating costs the expected return 
on the scheme’s assets and the increase during the period in the 
present value of the scheme’s liabilities arising from the passage 
of time are included in other finance income or cost
actuarial gains and losses arising from experience adjustments 
changes in actuarial assumptions and amendments to pension 
plans are charged or credited to equity and recorded in the 
statement of comprehensive income
contributions to defined contribution pension schemes are 
charged to the income statement in the period in which they  
fall due
q provisions
provisions are recognised where
• there is a present obligation as a result of a past event
• it is probable that there will be an outflow of economic 
benefits to settle this obligation and
• a reliable estimate of this amount can be made
insurance provisions are recognised for claims notified and for 
claims incurred but which have not yet been notified based on 
advice from the group’s independent insurance advisers
provisions are discounted to present value using a pretax 
discount rate that reflects the risks specific to the liability where 
the effect is material
r purchase of own shares
the group balance sheet includes the shares held by the severn 
trent employee share ownership trust and which have not 
vested unconditionally by the balance sheet date these are 
shown as a deduction from shareholders’ funds until such time 
as they vest
s financial instruments
i financial assets
financial assets are classified into the following specified 
categories
• at fair value through profit or loss
• held to maturity investments
• available for sale financial assets and
• loans and receivables
financial assets at fair value through profit or loss
a financial asset is classified at fair value through profit or loss if 
it is so designated or if it is held for trading derivative financial 
assets that are not designated and effective as hedging 
instruments are classified as held for trading financial assets at 
fair value through profit or loss are stated at fair value with any 
gains or losses arising on remeasurement recognised in  
gainslosses on financial instruments in the income statement 
fair value is determined using the methodology described in 
note 32 interest receivable in respect of derivative financial 
assets is included in finance income
held to maturity investments
where the group has the ability and intent to hold an investment 
to maturity the financial asset is classified as held to maturity 
such financial assets are measured at amortised cost using the 
effective interest rate method with any gains or losses being 
recognised in the income statement
2 accounting policies continued
l grants and contributions continued severn trent plc annual report and accounts 2011 68
notes to the group financial statements continued
for the year ended 31 march 2011
available for sale financial assets
after initial recognition at cost being the fair value of the 
consideration paid investments which are classified as 
available for sale are measured at fair value with gains or losses 
recognised in equity when an available for sale investment is 
disposed of or impaired the gain or loss previously recognised in 
equity is taken to the income statement where there is no active 
market in the investments and the fair value cannot be measured 
reliably the investments are held at cost
loans and receivables
trade receivables loans and other receivables that have fixed  
or determinable payments and that are not quoted in an active 
market are classified as loans and receivables such assets are 
measured at fair value on initial recognition and are subsequently 
measured at amortised cost using the effective interest rate 
method unless there is objective evidence that the asset is 
impaired where it is written down to its recoverable amount and 
the irrecoverable amount is recognised as an expense
trade receivables that are assessed not to be impaired 
individually are assessed collectively for impairment by reference 
to the group’s historical collection experience for receivables of 
similar age
ii financial liabilities
financial liabilities are classified as either
• financial liabilities at fair value through profit or loss or
• other financial liabilities
financial liabilities at fair value through profit or loss
a financial liability is classified at fair value through profit or loss 
if it is so designated or if it is held for trading derivative financial 
liabilities that are not designated and effective as hedging 
instruments are classified as held for trading financial liabilities 
at fair value through profit or loss are stated at fair value with 
any gains or losses arising on remeasurement recognised in 
gainslosses on financial instruments in the income statement 
fair value is determined using the methodology described in 
note 32 interest payable in respect of derivative financial 
liabilities is included in finance costs
other financial liabilities
other financial liabilities including borrowings are initially 
recognised at fair value less transaction costs after initial 
recognition other financial liabilities are subsequently measured 
at amortised cost using the effective interest rate method
iii hedge accounting
the group uses derivative financial instruments such as cross 
currency swaps forward currency contracts and interest rate 
swaps to hedge its risks associated with foreign currency and 
interest rate fluctuations such derivative instruments are 
recognised and measured in accordance with the accounting 
policies described above 
at the inception of the hedge relationship the group documents
• the relationship between the hedging instrument and the 
hedged item
• its risk management objectives and strategy for undertaking 
hedge transactions and
• whether the hedging instrument is highly effective in 
offsetting changes in fair values or cash flows as 
appropriate of the hedged item
the group continues to test and document the effectiveness of 
the hedge on an ongoing basis
hedge accounting is discontinued when the hedging instrument 
expires is sold terminated or exercised or no longer qualifies 
for hedge accounting
fair value hedges
where a loan or borrowing is in a fair value hedging relationship 
it is remeasured for changes in fair value of the hedged risk at 
the balance sheet date with gains or losses being recognised in 
gainslosses on financial instruments in the income statement 
the gain or loss on the hedging instrument is taken to gains
losses on financial instruments in the income statement where 
the effective portion of the hedge will offset the gain or loss on 
the hedged item
when hedge accounting is discontinued the fair value 
adjustment to the carrying amount of the hedged item arising 
from the hedged risk is amortised to the income statement from 
that date
cash flow hedges
the portion of the gain or loss on the hedging instrument that  
is determined to be an effective hedge is recognised directly in 
equity and the ineffective portion in gainslosses on financial 
instruments in the income statement the gains or losses 
deferred in equity in this way are recycled through gainslosses 
on financial instruments in the income statement in the same 
period in which the hedged underlying transaction or firm 
commitment is recognised in the income statement
when hedge accounting is discontinued any cumulative gain  
or loss on the hedging instrument recognised in equity is kept  
in equity until the forecast transaction occurs or transferred  
to gainslosses on financial instruments in the income statement 
if the forecast transaction is no longer expected to occur
hedges of net investments in foreign operations
where forward currency contracts and foreign currency 
borrowings are used to hedge net investments in foreign 
currency denominated operations to the extent that they are 
designated and effective as net investment hedges they are 
matched in equity against changes in value of the related assets 
any ineffectiveness is taken to gainslosses on financial 
instruments in the income statement
iv embedded derivatives
derivatives embedded in other financial instruments or other 
host contracts are treated as separate derivatives when their 
risks and characteristics are not closely related to those of the 
host contract and the host contract is not carried at fair value 
with gains and losses reported in gainslosses on financial 
instruments in the income statement
t share based payments
the group operates a number of equity settled share based 
compensation plans for employees the fair value of the 
employee services received in exchange for the grant is 
recognised as an expense over the vesting period of the grant
the fair value of employee services is determined by reference 
to the fair value of the awards granted calculated using an 
appropriate pricing model excluding the impact of any  
nonmarket vesting conditions the number of awards that are 
expected to vest takes into account nonmarket vesting 
conditions including where appropriate continuing employment 
by the group the charge is adjusted to reflect shares that do not 
vest as a result of failing to meet a nonmarket condition

financial statements
u cash and cash equivalents
for the purpose of the cash flow statement cash and cash 
equivalents include highly liquid investments that are readily 
convertible to known amounts of cash and which are subject to 
an insignificant risk of change in value such investments are 
normally those with less than three months’ maturity from the 
date of acquisition and include cash and bank balances and 
investments in liquid funds cash and cash equivalents also 
include overdrafts repayable on demand
v foreign currency
the results of overseas subsidiary and associated undertakings 
are translated into sterling the presentational currency of the 
group using average rates of exchange ruling during the year
the net investments in overseas subsidiary and associated 
undertakings are translated into sterling at the rates of exchange 
ruling at the year end exchange differences thus arising are 
treated as movements in equity on disposal of a foreign 
currency denominated subsidiary the deferred cumulative 
amount recognised in equity since 1 april 2004 relating to that 
entity is recognised in the income statement under the 
transitional rule of ifrs 1
exchange differences arising in respect of foreign exchange 
instruments taken out as hedges of overseas investments are 
also treated as movements in equity to the extent that the hedge 
is effective see note 2 s
all other foreign currency denominated assets and liabilities of 
the company and its subsidiary undertakings are translated into 
the relevant functional currency at the rates of exchange ruling at 
the year end any exchange differences so arising are dealt with 
through the income statement 
foreign currency transactions arising during the year are 
translated into sterling at the rate of exchange ruling on the date 
of the transaction all profits and losses on exchange arising 
during the year are dealt with through the income statement
w discontinued operations and assets held for sale
where an asset or group of assets a disposal group is available 
for immediate sale and the sale is highly probable and expected 
to occur within one year then the disposal group is deemed as 
held for sale the disposal group is measured at the lower of the 
carrying amount and fair value less costs to sell
where a group of assets which comprises operations that can 
be clearly distinguished operationally and for financial reporting 
purposes from the rest of the group a component has been 
disposed of or classified as held for sale and it
• represents a separate major line of business or geographical 
area of operations or
• is part of a single coordinated plan to dispose of a separate 
major line of business or geographical area of operations or
• is a subsidiary acquired exclusively with a view to resale
then the component is classified as a discontinued operation
noncurrent assets classified as held for sale are measured at 
the lower of carrying amount and fair value less costs to sell 
depreciation is not charged on such assets
3 new accounting policies and future requirements
ias 27 revised was required to be implemented by the group 
from 1 april 2010 the revised standard requires the effects of  
all transactions with noncontrolling interests to be recorded in 
equity if there is no change in control the standard also 
specifies the accounting when control is lost the group has had 
no transactions in the current or prior year that would have been 
impacted by the revised standard
ifrs 3 revised was also required to be implemented by the 
group from 1 april 2010 the standard continues to apply the 
acquisition method to business combinations with some 
significant changes the group has had no significant 
transactions in the current or prior year that would have been 
impacted by the revised standard
ifric 18 “transfers of assets from customers” was issued in 
january 2009 and was required to be applied with effect from  
1 april 2010 for assets transferred after 1 july 2009 where 
property plant and equipment is transferred the fair value of the 
asset is recognised in the balance sheet where the transfer is  
in exchange for connection to the network the corresponding 
credit is recognised immediately in turnover however in most 
cases the transfer is considered to be linked to the provision of 
ongoing services and in these cases the corresponding credit is 
recorded in deferred income and released to operating costs 
over the expected useful lives of the related assets the impact 
of the adoption of ifric 18 on the comparative figures presented 
in these financial statements is summarised below

the following standards have been issued by the international 
accounting standards board and are likely to affect future 
financial statements
ifrs 9 “financial instruments” is likely to affect the 
measurement and disclosure of financial instruments the 
standard is required to be implemented by the group with effect 
from the year ending 31 march 2014 subject to eu 
endorsement 
ifrs 10 “consolidated financial statements” was issued in may 
2011 and is required to be implemented by the group from 1 april 
2013 the standard includes a new definition of control to be 
used to determine when entities are consolidated the standard 
is not expected to have a material impact on the current 
consolidation
ifrs 11 “joint agreements” was issued in may 2011 and is 
required to be implemented by the group from 1 april 2013  
ifrs 11 replaces ias 31 “interests in joint ventures” and sic13 
“jointlycontrolled entities” ifrs 11 uses the definition of control 
given in ifrs 10 to define joint control and removes the option  
to account for joint ventures using proportionate consolidation 
this is not expected to have a material impact on the group

notes to the group financial statements continued
for the year ended 31 march 2011
4 significant accounting judgements and key 
sources of estimation uncertainty
in the process of applying the group’s accounting policies the 
group is required to make certain judgements estimates and 
assumptions that it believes are reasonable based on the 
information available
the more significant judgements were
a tax provisions
assessing the outcome of uncertain tax positions requires 
judgements to be made regarding the result of negotiations with 
and enquiries from tax authorities in a number of jurisdictions 
the assessments made are based on advice from independent 
tax advisers and the status of ongoing discussions with the 
relevant tax authorities
b provisions for other liabilities and charges
assessing the financial outcome of uncertain commercial and 
legal positions requires judgements to be made regarding the 
relative merits of each party’s case and the extent to which  
any claim against the group is likely to be successful the 
assessments made are based on advice from the group’s 
internal counsel and where appropriate independent  
legal advice
the key accounting estimates were
a goodwill impairment
determining whether goodwill is impaired requires an estimation 
of the value in use of the cashgenerating units cgu to  
which goodwill has been allocated the value in use calculation 
requires the group to estimate the future cash flows expected  
to arise from the cgu and a suitable discount rate to calculate 
present value details of the assumptions used are set out in 
note 16 to the financial statements
b depreciation and carrying amounts of property plant 
and equipment
calculating the depreciation charge and hence the carrying 
value for property plant and equipment requires estimates to be 
made of the useful lives of the assets the estimates are based 
on engineering data and the group’s experience of similar 
assets details are set out in note 2 j
c retirement benefit obligations
determining the amount of the group’s retirement benefit 
obligations and the net costs of providing such benefits requires 
assumptions to be made concerning long term interest rates 
inflation salary and pension increases investment returns and 
longevity of current and future pensioners changes in these 
assumptions could significantly impact the amount of the 
obligations or the cost of providing such benefits the group 
makes assumptions concerning these matters with the 
assistance of advice from independent qualified actuaries 
details of the assumptions made are set out in note 27 to the 
financial statements
d unbilled revenue
severn trent water raises bills and recognises revenue in 
accordance with its right to receive revenue in line with the limits 
established by the periodic regulatory price review processes 
for water and waste water customers with water meters the 
amount recognised is dependent upon the volume supplied 
including an estimate of the sales value of units supplied 
between the date of the last meter read and the year end meters 
are read on a cyclical basis and the group recognises revenue 
for unbilled amounts based on estimated usage from the last 
billing to the end of the financial year the estimated usage is 
based on historical data judgement and assumptions
e provision for impairment of trade receivables
provisions are made against severn trent water’s trade 
receivables based on historical experience of levels of recovery 
from accounts in a particular ageing category the actual 
amounts collected could differ from the estimated level of 
recovery which could impact operating results
5 segmental analysis
the group has two reportable segments severn trent water 
and severn trent services the key factor determining the 
identification of reportable segments is the regulatory 
environment in which the businesses operate severn trent 
water is subject to economic regulation by ofwat and operates 
under a licence to provide water and sewerage services within a 
defined geographical region in england and wales severn trent 
services is not subject to economic regulation and operates in 
markets in the usa europe and asia
the severn trent executive committee stec is considered to 
be the group’s chief operating decision maker the reports 
provided to stec include segmental information prepared on 
the basis described above details of severn trent water’s 
operations are described on pages 10 to 15 of the business 
review and those of severn trent services on pages 16 to 19
the group has a large and diverse customer base and there is 
no significant reliance on any single customer
ifrs 12 “disclosure of interests in other entities” was issued in 
may 2011 and is required to be implemented by the group from  
1 april 2013 the standard provides disclosure requirements for 
subsidiaries associates and joint agreements and structured 
entities which were previously covered in ias 27 ias 28 and ias 
31 additional disclosures will be required in the group financial 
statements to meet the requirements of the standard
ifrs 13 “fair value measurement” was issued in may 2011 and 
is required to be implemented by the group from 1 april 2013 
the standard provides additional guidance on how to measure 
fair value but does not change when fair value is permitted or 
required the standard may impact the methods of determining 
fair value which are currently employed by the group and will 
require enhanced disclosure of these methods 
the directors assess that the other standards and interpretations 
issued but not yet effective are not likely to have a significant 
impact on future financial statements

15 earnings per share
basic earnings per share are calculated by dividing the earnings attributable to ordinary shareholders by the weighted average 
number of ordinary shares in issue during the year excluding those held in the severn trent employee share ownership trust  
which are treated as cancelled
for diluted earnings per share the weighted average number of ordinary shares in issue is adjusted to assume conversion of all 
potentially dilutive ordinary shares these represent share options granted to employees where the exercise price is less than the 
average market price of the company’s shares during the year
basic and diluted earnings per share from continuing operations are calculated on the basis of profit from continuing operations 
attributable to the equity holders of the company
the calculation of basic and diluted earnings per share is based on the following data

changes in the growth rate outside the five year period or in the discount rate applied to the cash flows may cause a cgu’s carrying 
value to exceed its recoverable amount where such a change is considered reasonably possible the amount by which the 
recoverable amount exceeded its carrying value and the amount by which the growth rate and discount rate would have to change  
is set out below for each cgu

iii background
the group operates a number of defined benefit pension schemes in the uk covering the majority of uk employees the defined 
benefit schemes are funded to cover future salary and pension increases and their assets are held in separate funds administered  
by trustees the trustees are required to act in the best interests of the schemes’ beneficiaries a formal actuarial valuation of each 
scheme is carried out on behalf of the trustees at triennial intervals by an independent professionally qualified actuary under the 
defined benefit schemes members are entitled to retirement benefits calculated as a proportion varying between 
1
 30 and 
1
 80 for 
each year of service of their salary for the final year of employment with the group or if higher the average of the highest three 
consecutive years’ salary in the last ten years of employment 
the final salary sections of all of the pension schemes listed below are closed to new entrants and the age profile of scheme 
participants is expected to rise and hence service costs are also expected to rise in the future
on 11 may 2011 severn trent announced it is consulting with its 6000 plus uk employees on proposed changes to its pension 
arrangements which would see all existing pensions replaced by one new defined contribution scheme under the new proposals 
the group would close its defined benefit scheme to future accrual whilst protecting the benefits already built up by members
the uk defined benefit schemes and the date of their last formal actuarial valuation are as follows

the assumption for price inflation is derived from the difference between the yields on longer term fixed rate gilts and on indexlinked 
gilts the discount rate is set by reference to aa rated sterling corporate 17 year bonds 
the expected rate of return on scheme assets is based on market expectations at the beginning of the period for returns over the life 
of the benefit obligation for gilts and corporate bonds the expected rates of return are based on market yields for equities an equity 
risk premium has been added to the gilt rate
the mortality assumptions adopted are based on mortality tables applicable to the sex and year of birth of individual members with 
allowance for the cmi 2010 future improvements and a 05 trend for men the assumptions are based on 110 of the “saps” 
s1nmal tables and for women on 78 of the s1nfal tables these have been based on a mortality investigation carried out in 
conjunction with the valuation of the stps as at 31 march 2010 on behalf of the trustees
the life expectancies implied by the mortality assumptions adopted at each year end are as follows
years years
age to which current pensioners aged 65 are expected to live
 men 874 853
 women 910 886
age to which future pensioners aged 45 at the balance sheet date are expected to live

 women 918 896
the group has an obligation to pay pensions to a number of former employees whose benefits would otherwise have been restricted 
by the finance act 1989 earnings cap provision for such benefits amounting to £81 million 2010 £76 million is included as an 
unfunded scheme within the retirement benefit obligation
iv actuarial assumptions
the major assumptions used in the valuation of the stps also the approximate weighted average of assumptions used for the 
valuations of all group schemes were as follows severn trent plc annual report and accounts 2011 90
notes to the group financial statements continued
for the year ended 31 march 2011
assumption change in assumption impact on scheme liabilities
discount rate increasedecrease by 01 decreaseincrease by £30 million
price inflation increasedecrease by 01 increasedecrease by £25 million
mortality increase in life expectancy by 1 year increase by £45 million
the calculation of the scheme liabilities is sensitive to the actuarial assumptions and in particular to the assumptions relating to 
discount rate price inflation and mortality the following table summarises the estimated impact on scheme liabilities and service cost 
resulting from changes to key actuarial assumptions whilst holding all other assumptions constant
v contributions to the schemes
contribution rates are set in consultation with the trustees for each scheme and each participating employer the triennial actuarial 
valuation of the stps is currently under discussion with the trustees it is therefore not possible to determine the level of contributions 
that will be payable in the year ending 31 march 2012

stakeholder legislation and to provide the group with an alternative pension arrangement this was closed to new entrants on 1 april 
2005 and replaced by the severn trent stakeholder pension scheme
the total cost charged to operating costs of £49 million 2010 £45 million represents contributions payable to these schemes by the

e fair values of financial instruments
except as disclosed below the directors consider that the carrying amount of financial assets and liabilities recorded in the financial 
statements approximate their fair values
discounted future cash flows are used to determine fair values for debt discount rates are derived from yield curves based on quoted 
interest rates and are adjusted for the group’s credit risk
fair value measurements recognised in the balance sheet
the following table provides an analysis of financial instruments that are measured subsequent to initial recognition at fair value 
grouped into levels 1 to 3 based on the degree to which the fair value is observable
level 1 fair value measurements are those derived from quoted prices unadjusted in active markets for identical assets and 
liabilities
level 2 fair value measurements are those derived from inputs other than quoted prices included within level 1 that are observable 
for the asset or liability either directly or indirectly and
level 3 fair value measurements are those derived from valuation techniques that include inputs for the asset or liability that are not 
based on observable market data
the fair value of interest rate swaps is calculated as the present value of the estimated future cash flows estimated and discounted 
based on the application of yield curves derived from quoted interest rates
cross currency swaps and forward exchange contracts are valued by reference to quoted forward exchange rates at the balance 
sheet date and yield curves derived from quoted interest rates matching the maturities of the contracts

f financial risk factors
the group’s activities expose it to a variety of financial risks market risk including currency and interest rate risk credit risk liquidity 
risk and inflation risk the group’s overall risk management programme addresses the unpredictability of financial markets and seeks 
to reduce potential adverse effects on the group’s financial performance or position
financial risks are managed by a central treasury department group treasury under policies approved by the board of directors 
group treasury identifies evaluates and hedges financial risks in close cooperation with the group’s operating units the board 
provides written principles for overall risk management as well as written policies covering specific areas such as exchange rate risk 
interest rate risk credit risk the use of derivative and nonderivative financial instruments derivative financial instruments are used to 
hedge exposure to changes in exchange rates and interest rates the group’s policy is that derivative financial instruments are not

i market risk
the principal market risk that the group is exposed to is fluctuations in interest rates since substantially all of the group’s profits and 
net assets arise from severn trent water which has very limited and indirect exposure to changes in exchange rates the sensitivity 
of the group’s results to changes in exchange rates is not material
interest rate risk
the group’s income and operating cash flows are substantially independent of changes in market interest rates
the group’s interest rate risk arises from long term borrowings borrowings issued at variable rates expose the group to cash flow 
interest rate risk borrowings issued at fixed rates expose the group to fair value interest rate risk group policy is to maintain 4590 
of its net debt in fixed rate instruments at 31 march 2011 759 of the group’s net debt was fixed 2010 824
the group manages its cash flow interest rate risk by using floating to fixed interest rate swaps such interest rate swaps have the 
economic effect of converting borrowings from floating rates to fixed rates under the terms of the interest rate swaps the group 
agrees with other parties to exchange mainly semiannually the difference between fixed contract and floating rate interest rates 
calculated by reference to the agreed notional principal amounts the group has entered into a series of long dated interest rate 
swaps to hedge future debt economically these act to fix debt within the group which is denominated as floating rate but do not 
achieve hedge accounting under the strict criteria of ias 39 this has led to a £157 million charge 2010 credit of £419 million in  
the income statement
some of the group’s debt is indexlinked that is its cost is linked to changes in the retail price index rpi this debt provides an 
economic hedge for severn trent water’s revenues and regulatory capital value that are also rpi linked under its regulatory regime

exchange rate risk
the group operates internationally and is exposed to foreign exchange risk arising from net investments in foreign operations 
primarily with respect to the us dollar and the euro however since substantially all of the group’s profits and net assets arise from 
severn trent water which has very limited and indirect exposure to changes in exchange rates the sensitivity of the group’s results  
to changes in exchange rates is not material
the group has a significant value of foreign currency debt primarily in yen and euros the group’s policy is to manage the foreign 
exchange risk arising from foreign currency debt by entering into cross currency swaps or forward contracts with external parties
at 31 march 2011 the group had cross currency swaps or forward contracts in place for all foreign currency denominated debt

made to customers with an appropriate credit history other than in severn trent water limited whose operating licence obliges it  
to supply domestic customers even in cases where bills are not paid amounts provided against accounts receivable and movements 
on the provision during the year are disclosed in note 22 
for financing purpose derivative counterparties and cash transactions are limited to high credit quality financial institutions  
the group has policies that limit the amount of credit exposure to any one financial institution

monetary assets and liabilities by currency excluding functional currency
certain of the group’s subsidiaries operate in markets where the local currency is different from the functional currency of the 
operation exchange risks relating to such operations are managed centrally by group treasury through forward exchange contracts 
to buy or sell currency external foreign exchange contracts are designated at group level as hedges of foreign exchange risk on 
specific assets liabilities or future transactions on a gross basis the net amount of foreign currency assets and liabilities and the 
forward contracts that have been taken out to hedge the exchange risks on these assets and liabilities and on future committed

accounting is adopted for such instruments where the criteria set out in ias 39 are met
i fair value hedges
the group raises debt denominated in currencies other than sterling – principally japanese yen and euro cross currency swaps are 
entered into at the time that the debt is drawn down to swap the proceeds into sterling debt bearing interest based on libor in order 
to mitigate the group’s exposure to exchange rate fluctuations the terms of the receivable leg of the swap closely match the terms  
of the underlying debt hence the swaps are expected to be effective hedges at the year end the amounts of cross currency swaps

ii cash flow hedges
the group has entered into interest rate swaps under which it has agreed to exchange the difference between fixed and floating 
interest rate amounts calculated on agreed notional principal amounts such contracts enable the group to mitigate the risk of 
changing interest rates on future cash flow exposures arising from issued variable rate debt the group also entered into a number of 
interest rate contracts with future start dates during the amp5 regulatory period such contracts enable the group to mitigate the risk 
of changing interest rates on debt which is highly probable to be issued over the amp5 period to fund severn trent water’s capital 
programme and have been accounted for as cash flow hedges the fair value of interest rate swaps at the balance sheet date is 
determined by discounting the future cash flows using the yield curve prevailing at the balance sheet date and the credit risk inherent 
in the contract
the interest rate swaps primarily settle net on a biannual basis the floating rate on the interest rate swaps is six months libor

severn trent share price volatility is based on observations of historical weekly volatility over a period prior to grant commensurate 
with the remaining term of the performance period for each award 
for the july 2010 ltip award and the july 2009 award the comparator group is the group of companies ranked 51 – 150 in the  
ftse index excluding investment trusts
the volatility of the comparator companies the correlation between severn trent and the comparator companies and performance 
over the portion of the performance period that had elapsed at the date of grant was taken into account when modelling the tsr 
performance condition
the share price at the grant date was £1228 2010 £1134 the vesting period commences before the grant date performance in 
the vesting period prior to the grant date is taken into account in determining the fair value of the award 
dividends ‘paid’ on shares during the vesting period are accumulated during the vesting period and released subject to achievement 
of the performance condition in the same manner as the underlying shares as a result a dividend yield assumption is not required
the 2009 services ltip is based entirely on nonmarket conditions and hence market assumptions are not required to determine the 
fair value of the award for 2011 it has been assumed that performance against the services ltip nonmarket conditions will be 03

1 accounting policies
a basis of accounting
the financial statements have been prepared under the 
historical cost convention as modified by the revaluation of 
financial assets and liabilities including derivative instruments 
at fair value through profit or loss and in accordance with 
applicable united kingdom accounting standards and comply 
with the requirements of the united kingdom companies act 
2006 ‘the act’
b tangible fixed assets and depreciation

depreciation freehold land is not depreciated other assets  
are depreciated on a straight line basis over their estimated 
economic lives which are principally as follows
financial assets at fair value through profit or loss
a financial asset is classified at fair value through profit or loss if 
it is so designated or if it is held for trading derivative financial 
assets that are not designated and effective as hedging 
instruments are classified as held for trading financial assets at 
fair value through profit or loss are stated at fair value with any 
gains or losses arising on remeasurement recognised in gains
losses on financial instruments in the income statement fair 
value is determined using the methodology described in note 32 
to the group’s financial statements interest receivable in respect 
of derivative financial assets is included in finance income
held to maturity investments
where the company has the ability and intent to hold an 
investment to maturity the financial asset is classified as held to 
maturity such financial assets are measured at amortised cost 
using the effective interest rate method with any gains or losses 
being recognised in the income statement
available for sale financial assets
after initial recognition at cost being the fair value of the 
consideration paid investments which are classified as 
available for sale are measured at fair value with gains or losses 
recognised in equity when an available for sale investment is 
disposed of or impaired the gain or loss previously recognised 
in equity is taken to the income statement where there is no 
active market in the investments and the fair value cannot be 
measured reliably the investments are held at cost
loans and receivables
trade receivables loans and other receivables that have fixed  
or determinable payments and that are not quoted in an active 
market are classified as loans and receivables such assets  
are measured at fair value on initial recognition and are 
subsequently measured at amortised cost using the  
effective interest rate method unless there is objective  
evidence that the asset is impaired where it is written down  
to its recoverable amount and the irrecoverable amount is 
recognised as an expense
ii financial liabilities
financial liabilities are classified as either
• financial liabilities at fair value through profit or loss or
• other financial liabilities
financial liabilities at fair value through profit or loss

c leased assets
where assets are financed by leasing arrangements which 
transfer substantially all the risks and rewards of ownership of an 
asset to the lessee finance leases the assets are accounted 
for as if they had been purchased and the fair values of the 
minimum lease payments are shown as an obligation to the 
lessor lease payments are treated as consisting of a capital 
element and a finance charge the capital element reducing the 
obligation to the lessor and the finance charge being written off 
to the profit and loss account over the period of the lease in 
proportion to the capital amount outstanding depreciation is 
charged over the shorter of the estimated useful life and the 
lease period all other leases are accounted for as operating 
leases rental costs arising under operating leases are charged 
to the profit and loss account on a straight line basis over the life 
of the lease
d impairment of fixed assets and investments
impairments of fixed assets and investments are calculated  
as the difference between the carrying values of net assets  
of income generating units including where appropriate 
investments and goodwill and their recoverable amounts 
recoverable amount is defined as the higher of net realisable 
value or estimated value in use at the date the impairment review 
is undertaken net realisable value represents the net amount 
that can be generated through sale of assets value in use 
represents the present value of expected future cash flows 
discounted on a pretax basis using the estimated cost of capital 
of the income generating unit impairment reviews are carried 
out if there is some indication that an impairment may have 
occurred or where otherwise required to ensure that goodwill 
and fixed assets are not carried above their estimated 
recoverable amounts impairments are recognised in the  
profit and loss account and where material are disclosed  
as exceptional
e financial instruments
i financial assets
financial assets are classified into the following specified 
categories
• at fair value through profit or loss
• held to maturity investments
• available for sale financial assets and
• loans and receivables severn trent plc annual report and accounts 2011 115
financial statements
iii hedge accounting
the company uses derivative financial instruments such as 
cross currency swaps forward currency contracts and interest 
rate swaps to hedge its risks associated with foreign currency 
and interest rate fluctuations such derivative instruments are 
recognised and measured in accordance with the accounting 
policies described above 
at the inception of the hedge relationship the company 
documents
• the relationship between the hedging instrument and the 
hedged item
• its risk management objectives and strategy for undertaking 
hedge transactions and
• whether the hedging instrument is highly effective in 
offsetting changes in fair values or cash flows as 
appropriate of the hedged item
the company continues to test and document the effectiveness 
of the hedge on an ongoing basis
hedge accounting is discontinued when the hedging instrument 
expires is sold terminated or exercised or no longer qualifies 
for hedge accounting
fair value hedges
where a loan or borrowing is in a fair value hedging relationship 
it is remeasured for changes in fair value of the hedged risk at 
the balance sheet date with gains or losses being recognised in 
gainslosses on financial instruments in the income statement 
the gain or loss on the hedging instrument is taken to gains
losses on financial instruments in the income statement where 
the effective portion of the hedge will offset the gain or loss on 
the hedged item
when hedge accounting is discontinued the fair value 
adjustment to the carrying amount of the hedged item arising 
from the hedged risk is amortised to the income statement  
from that date
cash flow hedges
the portion of the gain or loss on the hedging instrument that  
is determined to be an effective hedge is recognised directly in 
equity and the ineffective portion in gainslosses on financial 
instruments in the income statement the gains or losses 
deferred in equity in this way are recycled through gainslosses 
on financial instruments in the income statement in the same 
period in which the hedged underlying transaction or firm 
commitment is recognised in the income statement
when hedge accounting is discontinued any cumulative gain  
or loss on the hedging instrument recognised in equity is kept  
in equity until the forecast transaction occurs or transferred  
to gainslosses on financial instruments in the income statement 
if the forecast transaction is no longer expected to occur
hedges of net investments in foreign operations
where forward currency contracts and foreign currency 
borrowings are used to hedge net investments in foreign 
currency denominated operations to the extent that they are 
designated and effective as net investment hedges they are 
matched in equity against changes in value of the related assets 
any ineffectiveness is taken to gainslosses on financial 
instruments in the income statement
iv embedded derivatives
derivatives embedded in other financial instruments or other 
host contracts are treated as separate derivatives when their 
risks and characteristics are not closely related to those of the 
host contract and the host contract is not carried at fair value 
with gains and losses reported in gainslosses on financial 
instruments in the income statement
f investments
investments in subsidiary undertakings are held at  
historical cost
after initial recognition at cost being the fair value of the 
consideration paid investments which are classified as held  
for trading or available for sale are measured at fair value with 
gains or losses recognised in income or equity respectively 
when an available for sale investment is disposed of or 
impaired the gain or loss previously recognised in reserves  
is taken to the profit and loss account
g share based payments
the company operates a number of equity settled share based 
compensation plans for employees the fair value of the 
employee services received in exchange for the grant is 
recognised as an expense over the vesting period of the grant
the fair value of employee services is determined by reference 
to the fair value of the awards granted calculated using a pricing 
model excluding the impact of any nonmarket conditions  
the number of awards expected to vest takes into account 
nonmarket vesting conditions including where appropriate 
continuing employment by the group the charge is adjusted  
to reflect shares that do not vest as a result of failing to meet  
a nonmarket based condition
h cash flow statement
the company has taken advantage of the exemption under 
financial reporting statement 1 ‘cash flow statements’ and  
not produced a cash flow statement
i deferred taxation
deferred taxation is fully provided for in respect of timing 
differences between the treatment of certain items for taxation 
and accounting purposes only to the extent that the company 
has an obligation to pay more tax in the future or a right to pay 
less tax in the future deferred tax assets are only recognised to 
the extent that taxable profits are expected to arise in the future 
material deferred taxation balances arising are discounted by 
applying an appropriate risk free discount rate
j pensions
the company participates in the group’s defined benefit and 
defined contribution pension schemes details of which are set 
out in note 27 to the group financial statements however the 
company is currently unable to identify its share of assets and 
liabilities relating to the defined benefit schemes the pension 
costs charged against the operating profit are the contributions 
payable to the scheme in respect of the accounting period in 
respect of the defined benefit and defined contribution schemes

shareholder security
many companies have become aware that their shareholders have 
received unsolicited phone calls or correspondence concerning 
investment matters these are typically from overseas based 
‘brokers’ who target uk shareholders offering to sell them what 
often turn out to be worthless or high risk shares in us or uk 
investments these operations are commonly known as ‘boiler 
rooms’ these ‘brokers’ can be very persistent and extremely 
persuasive and the number of instances of this type of fraud has 
increased dramatically in recent years a 2006 survey by the 
financial services authority fsa has reported that the average 
amount lost by investors is around £20000 it is not just the novice 
investor that has been duped in this way many of the victims had 
been successfully investing for several years
in addition in the current economic climate boiler rooms are now 
targeting victims who have redundancy money or those who are 
not experienced investors and are asking for smaller sums of 
money to be invested

• ensure you get the full name of the person and organisation 
• check that they are properly authorised by the fsa before 
getting involved by visiting wwwfsagovukregister
• report the matter to the fsa either by calling 0300 500 5000  
or visiting wwwmoneymadeclearfsagovuk and 
• if the calls persist hang up
please be aware that if you deal with an unauthorised firm you 
will not be eligible to receive payment under the financial 
services compensation scheme the fsa can be contacted by 
completing an online form at wwwfsagovukpagesdoing
regulatedlaw alertsoverseasshtml

advice offers to buy shares at a discount or offers of free 
company reports details of any share dealing facilities that the 
company endorses will be included in company mailings or on
