covs 136 92 tplayout 1  03032014  1343  page 9 overview of 2013
the group achieved record results in 2013 
with annual revenue growth of 10 proﬁt
before tax grew 25 and earnings per share
26 notwithstanding capacity expansion
investments and two small acquisitions strong
cash generation enabled the group to ﬁnish the
year free of net debt for the ﬁrst time order
books carried forward into 2014 are healthy
orders for aviation ﬁltration products grew 
14 in 2013 driven by recent new product
introductions nuclear and bioscience orders
were also strong sales to environmental
laboratories were up 13 after a slow start
revenues from metals filtration improved in 
the second half to ﬁnish up 2 for the year
several large contracts were announced in
energy markets during the year these will have
a signiﬁcant beneﬁcial impact on the group
results through to 2017 with the initial beneﬁts
showing in the 2013 results
capital investments were made in 2013 to
expand uk aviation and chinese manufacturing
capacity further such investments are planned
for 2014 in order to support longer term growth
plans for investment and future development
in 2013 porvair achieved two signiﬁcant
milestones large contracts were secured 
that will underpin manufacturing activity in
microﬁltration for at least the next two years 
and strong underlying trading enabled the
group to ﬁnish the year with net cash on the
balance sheet
together these will enable a period of
accelerated investment in 2014 we plan to
increase capital investment substantially 
• we intend to consolidate and expand our uk
facilities at new milton in order to free space
for aviation and industrial ﬁltration growth in
fareham aviation sales have grown strongly
recently and we need more capacity 
• following the acquisition of the trade and
assets of eisenmann metallurgical llc in june
2013 we will expand its manufacturing facility
in caribou maine during 2014 and invest in
production equipment to increase its capacity
• having built a new factory at xiaogan china
for metals filtration in 2013 we expect to
expand its production capability and capacity
in 2014 
• we will make further investments in the
production capabilities in the us
these and other projects will increase expected
capital investment in 2014 to around three 
times its level of recent years capacity increases
and equipment upgrades are necessary due 
to the impact that new product introductions
have had on the business we expect this
capacity pressure to continue with the 2014
product development pipeline looking promising
interesting work is going on in bioscience
ﬁltration metals ﬁltration manufacturing water
analysis nuclear ﬁltration and others
encouraging these projects is central to 
porvair’s business model
the 2013 results show the early beneﬁts of 
the large contract wins and these will become
even more apparent in 2014 the contracts in
question are principally those with posco the
uk government and reliance industries all of
which have been previously announced the
ﬁnancial impact of these contracts is expected
to cause the published results over the next
three to four years to ﬂuctuate more than has
generally been the case
• multiyear contracts are recognised under
longterm accounting rules which means that
revenues are expected to receive a oneoff
boost in 2014 causing them to be higher than
the underlying growth rate the group would
normally deliver revenues might then be
expected to return to the underlying levels 
in 2015
• proﬁts are recognised only after due
consideration of the potential risks outstanding
liabilities and warranties on each project proﬁt
recognition could therefore be spread over the
period between 2013 and 2017 
• net cash inﬂows are expected to arise
principally in 2013 and 2014 whilst we will
maintain suitable cash reserves against the
possible needs of the contracts this cash will
be used to reinvest in the business as
outlined above

strategy and business model
our strategy
porvair’s strategy has remained consistent for several years 
it is to generate shareholder value through the development of
specialist filtration and environmental technology businesses both
organically and by acquisition such businesses have certain key
characteristics in common 
• specialist design or engineering skills are required
• product use and replacement is mandated by regulation quality
accreditation or a maintenance cycle and
• products will be designed into a specification and will typically 
have long life cycles
since 2007 this strategy has delivered revenue growth of 85 
11 cagr and cash from operations of £48 million in 2013 
the group’s after tax operating profit return on operating capital

porvair’s business model is as follows
focus on endmarkets which show long term growth potential
and where product use is mandatory
make new product development a core business activity
establish geographic presence where endmarkets require
maintain a conservative balance sheet reinvest in both
organic and acquired growth and pay a progressive dividend
this business model determines the
group’s daytoday activities
how our strategy and business
model work together
our strengths
• we focus on four endmarkets aviation energy and
industrial environmental laboratories and molten
metals all have clear structural growth drivers 
• our products are specialist in nature they typically
protect more costly or complex downstream systems
as a result they are replaced regularly over 80 
of our annual revenues are from repeat orders
• we encourage new product development in order 
to generate growth rates in excess of the underlying
market around 35 of our annual revenues are
now derived from recent product introductions 
we try to build good intellectual property around our
product developments about 30 of our revenues
are derived from patent protected products
• our geographic presence follows the markets we
serve 46 of revenues are from the americas
where aviation and metals ﬁltration are strong 
18 of revenues are in asia and australasia where
sales into water analysis markets are growing
• porvair is a cash generative business we aim to
maintain a conservative balance sheet meeting
dividend and investment needs within our existing
debt facilities and generating free cash ﬂow to pay
down debt in the last two years we have expanded
manufacturing capacity in the uk and china and
made ﬁve small acquisitions 
operating structure
• the group has two divisions the microﬁltration
division serves the aviation environmental laboratory
and energyindustrial markets the metals filtration
division serves global aluminium nafta iron foundry
and super alloy markets

lithium aluminium filter
customer need
lithium aluminium is a stronger
lighter alloy than aluminium with 
a growing use in the aerospace
industry  in common with
aluminium it needs to be ﬁltered
to produce high purity metal
however in its molten state it
corrodes traditional ﬁlters
porvair’s response
porvair has developed and is
testing a new ﬁlter using a
different ceramic formulation to
signiﬁcantly reduce corrosion 
and thereby produce higher 
purity metal

covs 136 92 tplayout 1  03032014  1344  page 15 divisional review – metals filtration
performance in 2013
after a slow start to 2013 the metals filtration
division had a stronger second half finishing
the year with record revenues of £285 million 
the board was pleased to note that this
division was better able to cope with a modest
sales downturn in early 2013 than had
previously been the case this is mainly due 
to higher operating margins achieved in recent
years with patented products accounting for
the majority of sales in this division despite
the slower start to the year operating profits
finished in line with 2012’s record result 
of £24 million
conditions in this division’s endmarkets 
have been mixed across the year with global
aluminium pricing relatively low but nafta
auto production staying at satisfactory levels
in this environment we have been able to build
market share by demonstrating superior
product performance we have three main
product ranges all patented 
• selee csx™ for aluminium filtration where
we have a high global market share this
product has a unique environmental footprint
in being free of phosphates
• selee ic™ for gray and ductile iron filtration
this range is sold principally in the us and
offers excellent filtration efficiency
• selee sa™ for the filtration of nickelcobalt
alloys this niche application requires
exceptional filtration performance and uses 
a highly proprietary manufacturing technique
the product development pipeline in this
division is promising in recent months we
have successfully trialed a new aluminium 
filter for high grade lithium alloys that are
increasingly used in aerospace applications
as previously noted we have been developing
an entirely new design of filter over the last 
18 months and this work continues to go
well several successful customer trials 
have been held and we are making modest
revenues from this project in 2014 we will
start to see whether this remains a niche
application or whether it can develop into 
a more substantial programme
a new plant was built at xiaogan in china in
the year the new facility is substantially larger
than its predecessor and was built on time
and under budget production started in the
final quarter we plan to develop this facility 
to meet the needs of the domestic chinese
market further investment in production
equipment will be necessary with installation
likely towards the end of 2014

divisional review – microfiltration
performance in 2013
the microfiltration division had a good year with
revenues increasing 15to a record £558 million
order books going into 2014 are healthy
several large contracts are now underway in
this division all are proceeding satisfactorily 
a second delivery under the us10 million
posco contract was made towards the end
of 2013 posco expect to start production
trials of its plant that turns coal to substitute
natural gas at gwangyang south korea later 
in 2014 a much larger contract for a similar
project was signed in february 2013 with
reliance industries for their plant at jamnagar
india the scope of this work was extended 
in april and again in august finally an 
£113 million contract with the uk government
was announced in january 2013 for deliveries
starting in 2014 the likely beneficial financial
impact of these projects is discussed on page 7
orders in aviation and nuclear filtration have
grown again in 2013 with a 14 increase in
aviation orders meaning we are starting to hit
capacity constraints as noted on page 7 we
will expand our facilities both in the uk and us 
to provide room for further growth
the us based operation grew 24 in 2013 a
good result excluding the maiden contribution
from eisenmann metallurgical “cem” acquired
in june 2013 cem is a good bolton acquisition
for the group bringing product and market
expertise with a committed and skillful workforce
in caribou maine as noted on page 7 we will
invest in this facility in 2014 to allow room for
growth and have an expanded management
and commercial team in place to drive further
growth trading at cem since acquisition has
been satisfactory with integration activities
focused on it and financial systems this work
is complete with the caribou facility now
operating well as a satellite plant
we have been working for several years 
on some interesting intellectual property in
bioscience filtration a patented dna filtration
product is under development in collaboration
with the university of swansea and with some
financial support from the welsh government
in an unrelated project an agreement was
struck with thermo fisher scientific “thermo”
under which porvair will licence its technology
to thermo who will market fritless solid phase
extraction columns under the sola brand
porvair will receive licence and royalty income
and manufacture the product for thermo this
sort of opportunity where porvair technology 
is licenced to others is of interest to the board
and results will be monitored closely
seal analytical revenues grew 13 helped 
by small acquisitions in 2012 and 2013 seal is
the market leading supplier of equipment and
consumables for the detection of inorganic
contamination in water a well defined niche
market that will grow as water quality standards
improve across the worldalthough its us
markets remained quiet for most of the year
demand from china was robust and parts of
europe showed the first signs of improvement
in several yearsdesign rights to a range of water
analysers were acquired early in the year and
these have transferred to seal’s us operation
cost savings have been found and
manufacturing is now fully integrated in
september the group purchased the trade 
and assets of thomas cain inc “cain” a
manufacturer of complementary instruments
and consumables initial trading at cain has
been satisfactory and the outlook for 2014 
is good

covs 136 92 tplayout 1  03032014  1344  page 18 group operating performance
the operating profit margin improved to 103
2012 94 this improvement arises from 
the benefit of higher revenue driving operational
gearing and a steady improvement in the quality
of business throughout the group following
several years of steadily improving margins in
metals filtration operating margins were
maintained in the year and the growth in
microfiltration was accompanied by a 17
improvement in operating margins in the year
the operating performance of the microfiltration
and metals filtration divisions are described in
detail in the chief executive’s report and below 
the operating loss associated with the other
unallocated segment was £24 million 2012
£19 million which mainly comprises group
corporate costs these include new business
development costs and general financial costs
the operating profit includes amortisation
charges on intangible assets arising on
acquisition of £02 million 2012 £01 million
acquisition expenses written off of £01 million
2012 £01 million and share based payment
charges of £05 million 2012 £04 million
impact of exchange rate movements 
on performance
the international nature of the group’s business
means that relative movements in exchange
rates can have a significant impact on reported
performance the average rate used for
translating the results of us operations into
sterling was us157£ 2012 us158£ 
and the group’s euro denominated operations
were translated at €118£ 2012 €122£ 
the slightly stronger dollar and stronger euro
rates accounted for 1 of the revenue growth
and 1 of the operating profit growth such that
currency differences on translation had only a
marginal impact compared with the prior year
the group sold forward the majority of its uk
business’ 2013 us dollar revenue during the
financial year and achieved rates between
151£ and 16£ similar to the rates 
achieved in 2012
at 30 november 2013 the group had 
us19 million of outstanding forward foreign
exchange contracts taken out to hedge the
future revenue on the group’s large contracts
the group has applied hedge accounting to
these transactions and a gain of £09 million 
is shown in the consolidated statement of
comprehensive income
finance costs
net interest payable decreased to £08 million
2012 £09 million included within interest
payable are finance costs in relation to the
defined benefit pension scheme which were
£04 million 2012 £04 million in the year
other net interest payable reduced as a result 
of lower borrowings and a lower margin on the
new facilities in place from january 2013
the group has a policy of maintaining between
40 and 60 of its borrowings on fixed interest
terms it achieved this by taking out interest rate
swaps to fix the interest rates on certain of its
borrowings these provided some protection
for the group in the event of interest rate rises
as a result of the significant decline in the
group’s borrowings in the year the group had
approximately 75 of its gross borrowings held
at a fixed rate at 30 november 2013 however
the fixed rate contracts expire shortly after the
year end for the time being while the group’s
gross borrowings are low the board has
concluded that further interest rate swaps need
not be taken out and the group’s borrowings
are at a floating rate from 13 december 2013
the contracts in place during the year are
summarised below
fixed rate principal amount principal terms
188 5 million effective from 
12 december 2010

the group tax charge was £24 million 2012
£20 million this is an effective rate of 30
2012 32 higher than the uk standard
corporate tax rate of 233 2012 247
mainly as a result of higher tax rates on profits

net working capital was tightly controlled 
and reduced by £11 million although revenue
rose by 10 in the year inventories increased
as a result of the increased revenue trade and
other receivables also increased a little as a
result of higher revenue but the majority of the
increase relates to advance payments made 
to suppliers in relation to the group’s large
contracts trade and other payables increased
significantly in part because of the receipt of
cash ahead of the recognition of revenue on 
the group’s large projects
net interest paid represents the bank interest
charged in the year it reduced as bank
borrowings fell in the year
tax payments in the us have increased
following the final utilisation in 2012 of past 
tax losses in the metals filtration division tax
payments are now more closely in line with 
the group’s tax charge
capital expenditure
capital expenditure was £20 million 2012 
£20 million offset by £05 million 2012 £nil
received on the disposal of a uk property the
principal investments in 2013 were a new plant
in xiaogan china for metals filtration and
additional plant in the microfiltration division 
to increase capacity principally to deliver 
growth in aerospace business
looking forward the board is planning
significant capital projects in 2014 to provide
new and upgraded plants in the uk us and
further increases to production capacity
throughout the group capital expenditure 
is likely to rise to around three times the 
normal level
acquisitions
the group invested £51 million in two us
based acquisitions in the year on 4 june 2013
the group purchased the trade and assets of
eisenmann metallurgical llc a manufacturer 
of specialist filters and on 20 september 2013
the group purchased the trade and assets 
of thomas cain inc a manufacturer of
environmental laboratory equipment and
consumables these acquisitions gave rise to
goodwill of £37 million £33 million was paid

in the year after charging £01 million of
acquisition costs 
it is estimated that had the acquisitions been
owned for a full year they would have contributed
£38 million of revenue and £07 million of
operating profit in the year
pension schemes
the group continues to support its defined
benefit pension scheme in the uk which is
closed to new members and to provide access
to defined contribution schemes for its us
employees and other uk employees
the group’s total pension cost was £14 million
2012 £12 million £10 million 2012 £08
million was recorded as an operating cost and
£04 million 2012 £04 million was recorded 
as a finance charge the group continues to
account for its pension schemes under ias 19
and will adopt ias 19 revised in the year ending
30 november 2014 had the group adopted 
ias 19 revised it is estimated that the group’s
pension charge in the year would have been 
£02 million higher
the group recorded a retirement benefit
obligation of £119 million 2012 £85 million
the increase in the deficit principally related to 
an actuarial loss in the year of £36 million 2012
£12 million which in turn arose as a result of a
change in the mortality assumptions the other
assumptions adopted were in line with the
previous year
the scheme had 53 2012 54 active members
289 2012 295 deferred members and 265
2012 265 pensioners at 30 november 2013
the life expectancy of members of the scheme 
at age 65 is assumed to be 215 years 2012
197 years for men and 237 years 2012 223
years for women
a full triennial actuarial valuation of the assets 
and liabilities of the defined benefit scheme was
completed in 2013 based on data at 31 march
2012 as a result of this review the group and
the trustees agreed to alter the employer’s
contributions from 82 of salary to 133 
of salary additionally the group committed to
make a £194000 annual contribution towards
the running costs of the scheme from march
2014 which will increase by 325 per annum
thereafter the group also committed to make
additional annual contributions to cover the 
past service deficit of £456000 per annum
commencing in december 2013 increasing 
by 5 per annum thereafter the funding shortfall
is expected to be eliminated by december 2027
the next full actuarial valuation of the scheme will
be based on the pension scheme’s position at 
31 march 2015 and is expected to be completed
before june 2016
borrowings and bank finance
at the year end the group had net cash
balances of £06 million 2012 net debt of £39

the group signed new five year borrowing
facilities on 25 january 2013 comprising a five
year us20 million revolving credit facility a 
£25 million term loan reduced to £175 million at
30 november 2013 and a £25 million overdraft
facility these facilities have margins ranging
between 195 and 225 a considerable
reduction on the margins of the previous facilities
which had margins of 27 the new facilities

risk description and impact
existing market risk
the group serves the needs of a range of specialist filtration
markets such that it is not dependent upon any one market
however its activities are spread across four key markets as
follows 
• aviation filtration where quality and accreditation of products 
are critical
• energy and industrial process filtration where projects tend 
to be large and demand would be affected by a sustained
economic downturn
• environmental laboratory supplies where revenue can be affected
by access to capital in customers’ markets municipalutilities 
and industrial labs and
• aluminium filtration where demand for aluminium can fluctuate
each of the above markets contribute more than 10 of the
group’s revenue and the group would be exposed to a significant
decline in any of these markets
mitigation change
no single market represents more than 30 of revenue many of 
the group’s products are consumable and are essential to the safe
operation of their respective systems and processes so whilst
volumes are impacted by changes in economic circumstances
significant fluctuations for other reasons are rare 
the aviation market has traditionally provided very steady business
as product cycles are long and the group offers a broad range of
products split evenly between aftermarket and new build the
outlook for the aviation market is for steady growth and the group
has a good pipeline of new long term supply contracts there is
unlikely to be such a rapid decline in aerospace demand that the
group could not manage the consequences over time  
the energy and industrial process products serve a range of
customers who use filters as an integral part of processes in their
plants sales are both for new build and after market spares  
environmental laboratory supplies are chiefly sold to laboratories
engaged in meeting the regulatory requirements for clean water  
it is expected that the regulated nature of this market will mitigate
cyclical changes this market is expected to grow as water
regulations tighten throughout the world and demand for clean 
water in the developing world increases the group is steadily
increasing its consumable revenue into this market and reducing 
its reliance on original equipment sales 
the group’s revenue is affected by the levels of aluminium
production however the group now has a stronger market 
position having successfully converted its customers to a new filter
formulation the production of aluminium is gradually moving to
larger smelters in regions of low cost energy the group is
developing its sales presence accordingly

risk description and impact
new products and markets risk
the group invests significant amounts into the development of 
new products often driven either by environmental imperatives or
legislation in the early stage of development there is a risk that 
these products will either not be adopted or that the legislation 
or regulation will not develop as anticipated
mitigation change
the group’s new product development is focused on solving 
specific challenges identified by the group’s customers this focus
on specific developments improves the adoption rate of the group’s
designs the group has brought a number of these products 
to market and is now less exposed to the risks associated with new
products the group maintains a close review of each of its major
developments and is not significantly exposed if the market for any
one product does not develop
risk description and impact
large contracts risk
the group currently has a number of large contracts for the
installation of filtration systems the group’s future results will be
affected by the outcome of these contracts and the potential future
revenue from the installations significant delays or engineering
challenges with these contracts could impact the group’s expected
performance 
mitigation change
these contracts have direct senior management involvement on 
a day to day basis the group makes every effort to ensure that 
its commitments are met on time and in full detailed engineering
and financial plans risk assessments and forecasts are maintained
for each of these projects the financial impact of reasonably
foreseeable risks are included in these plans reports are
produced every month which detail project progress and 
changes to planned schedules and assessment of risk
risk description and impact
raw materials resources and facilities risk
the group uses raw materials in its production processes 
prices for these raw materials can be volatile and are affected by 
the cyclical movement in commodity prices such as oil alumina 
gas and steel the group’s ability to pass on these price fluctuations
to its customers is to some extent dependent on the contracts it 
has entered into and the prevailing market conditions there may be
times when the group’s results are adversely affected by an inability
to recover increases in raw material prices 
the group operates a number of production facilities the largest
facility generating approximately one third of the group’s revenue 
a disaster such as a fire or flood at any of the group’s facilities 
could have a material impact on the group’s performance  
mitigation change
where practical the group seeks to fix its raw materials prices in 
long term contracts with suppliers and in certain cases uses forward
contracts to manage its exposure to fluctuating prices
the group maintains insurance of its equipment and facilities and
carries business interruption insurance to cover loss of profits in
addition the group has iso 9001 and other industry specific quality
control systems which reduce the risk that a disaster will occur
risk description and impact
competitive risk
porvair operates in competitive global markets the group’s
achievement of its objectives is reliant on its ability to respond 
to many competitive factors including but not limited to pricing
technological innovations product quality customer service
manufacturing capabilities and the employment of qualified personnel
if the group does not continue to compete in its markets effectively
by developing innovative solutions for its customers and delivering
high quality customer service it could lose its customers and its
results could be adversely affected
mitigation change
the group recognises that certain of its competitors are larger and
have greater financial resources this may enable them to deliver
products on more attractive terms than the group or to invest more
resources including research and development
through the development of a strategy that focuses on micro
niches within the group’s chosen markets the group seeks 
to identify specific opportunities where it has a commercial
reputational or technological advantage that enables it to 
compete successfully

risk description and impact
technological risk
porvair has a broad portfolio of products delivered to a diverse range
of markets the group’s business could be affected if it does not
continue to win new mandates for filtration solutions with designs
that provide technical or cost advantages over its competitors
mitigation change
the design and testing cycle of many of the group’s products takes
several years before a product is accepted by the customer once
the product is accepted and production commences products
often have a very long lifecycle the group therefore has good
visibility of its pipeline of opportunities for revenue growth however
the ultimate commercial success of a project can often only be
judged when the development cycle is close to completion
risk description and impact
financing risk
the group maintains a level of borrowing to finance its operations
damage to or loss of its banking relationships could have a material
impact on the profitability of the group 
mitigation change
to mitigate this risk the group has sufficient longterm facilities in
place for its expected requirements and has progressively reduced
its gearing it maintains a close relationship with its bankers and
carefully monitors the restrictions on its borrowings  
risk description and impact
pensions risk
the group operates a defined benefit pension scheme which 
is closed to new members but remains open for future accrual 
for the existing active members the group retains the ultimate
responsibility for ensuring that the trust has sufficient funds to ensure
that all current and future pensions can be paid in full a significant
shortfall in the value of the assets of the scheme compared with its
liabilities could require the company to make additional payments 
to the scheme
mitigation change
the pension scheme is financed through a separate trust fund 
and administered by a board of trustees with an independent
chairman the group maintains a close oversight of the pension
scheme through appointment of its own trustees to ensure that 
the scheme is properly administered and that sound investment
advice is obtained the group has a deficit recovery plan in place
that is affordable and expected to reduce the current deficit 
the deficit contribution is reviewed every three years as part of 
the triennial valuation

product liability risk
the group manufactures products that are potentially vital to the safe
operation of its customers’ products or processes a failure of the
group’s products could expose the group to loss as a result of claims
made by the group’s customers or users of their products  
mitigation change
the group seeks to minimise liabilities through limitations of liability 
in its contracts and carries insurance cover in the event that claims
are made

financial risk management
the group’s operations expose it to a variety of financial risks that
include the effects of
• price risk 
• foreign exchange risk 
• credit risk 
• liquidity risk and
• interest rate cash flow risk
mitigation change
the group has in place financial risk management procedures 
that seek to limit the adverse effects on the financial performance 
of financial risks the principal procedures are described below
price risk
the group is exposed to commodity price risk as a result of its
operations the group buys certain raw materials and energy 
on long term contracts to minimise its exposure to fluctuation in
commodity prices in all cases these contracts result in the ultimate
delivery and use by the group of the commodity the group has 
no exposure to equity securities price risk as it holds no listed 
or other equity investments
foreign exchange risk
the group seeks to manage its exposure to the impact of 
exchange rate movements on its net investments by maintaining
some borrowings in us dollars previously it sought to maintain
borrowings in us dollars equivalent to around 60 of the carrying
value of its us dollar net tangible assets in its us operations
however as the group’s overall borrowings have reduced so 
the us dollar borrowings have reduced to around 15 of its 
us dollar net assets
the uk operations of the business generate significant revenues 
in us dollars and the group seeks to minimise the impact of
movements in the us dollar exchange rate on the value of these 
us dollar flows by using financial instruments to fix the future value
of the us dollars the group does not apply hedge accounting 
to these transactions in the case of large contracts where the 
future currency income is in a different currency from the operations
functional currency is certain and can be specifically assigned 
to individual transactions the group takes out forward foreign
exchange contracts to minimise the impact of currency fluctuations
the group applies hedge accounting to these transactions
credit risk
the group has implemented policies that require appropriate 
credit checks on potential customers before sales are made 
debtor finance is very rarely used and is reviewed on a case by 
case basis by the board of directors the group monitors the level
of deposits held with overseas banks and financial institutions and
repatriates cash as part of its treasury management
liquidity risk
the group actively maintains a mixture of long term and short term
debt finance that is designed to ensure the group has sufficient
available funds for operations and planned expansions
interest rate cash flow risk
the group has only interest bearing liabilities the group seeks 
to maintain between 40 and 60 of its borrowings at a fixed
interest rate typically through fixed rate swap agreements 
the group applies hedge accounting to these instruments
as a result of the significant decline in the group’s borrowings in 
the year the group has approximately 75 of its gross borrowings
held at a fixed rate at 30 november 2013 however the fixed rate
contracts expired shortly after the year end for the time being while
the group’s gross borrowings are low the board has concluded 
that further interest rate swaps need not be taken out and the
group’s borrowings are at a floating rate from 13 december 2013

greenhouse gas emissions
the group has implemented the uk
government’s guidance on measuring and
reporting greenhouse gas emissions in line
with defra guidelines using conversion units
published by the carbon trust the group
reports ‘scope 1 and 2’ emissions in tonnes 
of carbon dioxide scope 1 covers direct
emissions those that emanate directly from
group operations this is principally natural gas
burned in manufacturing and fuel used in
company owned vehicles scope 2 covers
indirect emissions those generated by key
suppliers which is principally electricity
metals filtration in the us runs gas powered
furnaces to fire its ceramic filters the gas to
run these furnaces is the largest component 
of the group’s emissions electricity provides
heat light and power for the group’s premises
and other plant and equipment the plant 
and equipment is mainly light manufacturing
equipment but does include some high
pressure presses and electric furnaces

relationships with customers
the group’s products are generally bespoke
for specific customers and generally have a
very long product lifecycle this naturally
requires the group to build close relationships
with its customers over 80 of the group’s
annual revenue comes from repeat business
from existing customers
most new product introductions are developed
with existing customers and when new
customers are gained it is often after a long
development period over which a close
relationship has developed and a long term
relationship is expected
particularly in aerospace and energy the 
group builds relationships with the immediate
customer for the product and also with the
ultimate end user or manufacturer who is often
the party that certifies the product for example
the airframe manufacturer will be an important
stakeholder but the customer will usually be 
a subassembly manufacturer
relationships with suppliers
the group has an extensive network of
suppliers and subcontractors many of whom
are critical to the manufacture of specific parts
the group has a stable supplier base it seeks
to increase its supplier base by extending the
number of suppliers only where there are
perceived to be risks of under capacity or
resilience in its existing supply chain suppliers
are generally only removed from the approved
list for persistent quality or delivery failures
wherever possible the group seeks local
suppliers to fulfil its requirements the group
carefully selects its suppliers as part of building
a long term relationship with its critical suppliers
the group works closely with them to ensure
that the quality and delivery standards required
by the group are achieved
antibribery and corruption policy
the group seeks to prohibit all forms of bribery
and corruption within its business and complies
with the requirements of all applicable laws
designed to combat bribery and corruption
the group requires all employees agents
intermediaries and consultants to conduct
themselves in accordance with our antibribery
and corruption policy
porvair and the local community
the management of each operation is aware 
of its role within its local communities they
seek to recruit locally and retain a skilled local
workforce and are encouraged to build
relationships with local community
organisations
human rights
the group is aware of its requirements to
respect human rights in all jurisdictions in which
it operates there has however never been 
a human rights issue that has had a direct
impact on the activities of the business and
accordingly the group has nothing further 
to disclose

special resolution

seeks authority from shareholders for the company to make
market purchases of its own ordinary shares such authority
being limited to the purchase of 10 of the ordinary shares in
issue as at 24 january 2014 the maximum price payable for
the purchase by the company of its own ordinary shares will be
limited to the higher of i 5 above the average of the middle
market quotations of the company’s ordinary shares as derived
from the daily official list of the london stock exchange for

and the highest current independent bid for an ordinary share
as derived from the london stock exchange trading system
sets the minimum price payable by the company for the
purchase of its own ordinary shares will be 2 pence per share
being the nominal value of an ordinary share the authority 
to purchase the company’s own ordinary shares will only be
exercised if the directors consider that there is likely to be a
beneficial impact on earnings per ordinary share and that it is 
in the best interests of the company at the time the resolution
renews a similar resolution passed at the annual general
meeting of the company held on 16 april 2013 any ordinary
shares so purchased by the company will be held in treasury
by the company and will remain in issue and be capable of
being resold by the company or used in connection with
certain of its share schemes
to understand the impact of dilution options to subscribe for
up to 1613544 ordinary shares have been granted and are
outstanding as at 24 january 2014 being the latest practicable
date prior to publication of this document which if issued
would represent 36 of the issued ordinary share capital at
that date if the directors were to exercise in full the power for
which they are seeking authority under resolution 13 the
options outstanding as at 24 january 2014 would represent
39 of the ordinary share capital excluding shares held in
treasury in issue following such exercise
resolution 13 – calling of general meetings 
special resolution
resolution 13 to be proposed at the annual general meeting
seeks authority from shareholders to hold general meetings
other than annual general meetings on 14 days’ clear notice
this is permissible under the articles and the companies act
2006 however pursuant to the eu shareholders’s rights
directive the company must offer the facility accessible to all
shareholders to vote by electronic means and must obtain
specific shareholder approval on an annual basis to retain this
ability the directors believe that there may be circumstances 
in which it will be in the interests of the company to be able to
convene meetings at such short notice the shorter notice
period would not be used as a matter of course but only
where it is merited by the business of the meeting and is
thought to be to the advantage of the shareholders as a whole
accordingly the directors believe that it is important for the
company to retain this flexibility resolution 13 renews a similar
resolution passed at the annual general meeting of the
company held on 16 april 2013
resolution 14 – to establish a new save as you earn
“saye” scheme
resolution 14 to be proposed at the annual general meeting
seeks to reintroduce an hm revenue  customs approved
saye scheme the existing saye scheme that was

all uk employees to benefit from the future growth and 
success of the company

pages 43 to 46 we describe our remuneration policies and potential future outcomes for each executive director we also
describe our policy for rewarding nonexecutive directors

good practice and support the delivery of the group’s strategy 
in formulating its policy the committee has given full consideration to the requirements of section d of the uk corporate
governance code and the remuneration regulations
the committee aims to provide remuneration packages that
• are competitive but not excessive and are designed to attract retain and motivate managers of high quality to deliver
growth for the business
• are aligned with shareholders’ interests and have a significant proportion of the potential remuneration linked to the short
and medium term performance of the business
• include an element of the potential reward linked to personal performance and
• encourage the executive directors to accumulate shares in the company

in the event that the company recruits a new director either from within the organisation or externally when determining
appropriate remuneration arrangements the committee will take into consideration all relevant factors including but not limited
to quantum the type of remuneration being offered and the candidates’ background to ensure that arrangements are in the
best interests of both the company and its shareholders without paying more than is necessary to recruit a director of the
required calibre the committee would generally seek to align the remuneration package offered with the remuneration policy
outlined in the tables on page 44 
in the first year of appointment the committee may offer additional remuneration arrangements that it considers appropriate and
necessary to recruit and retain the individual such remuneration may be made in the form of cash or share based awards which
may vest immediately or at a future point in time vesting may be subject to performance conditions selected by the committee
the committee may make awards on appointing a director to “buyout” remuneration arrangements forfeited on leaving a
previous employer in doing so the committee will take account of relevant factors including any performance conditions
attached to these awards the form in which they were granted eg cash or shares and the time over which they would have
vested generally buyout awards will be made on a comparable basis to those forfeited
in the event of recruitment the committee may also grant awards to a new director under listing rule 942 which allows for the
granting of awards specifically to facilitate in unusual circumstances the recruitment or retention of a director without seeking
prior shareholder approval

the executive directors have rolling contracts with the company which can be terminated on giving twelve months’ notice
this is considered to be an appropriate balance between flexibility and commitment on both parties
payments for loss of office will be determined by the remuneration committee based on the contractual entitlements of the
director concerned under service contracts and the terms of the long term share plan the particular circumstances of the
director’s loss of office will determine whether mitigation of payments should apply and whether the payments that would
ordinarily be due under the discretionary annual bonus plan would be paid 
all employee share plans
the company also periodically offers invitations to uk employees to join save as you earn “saye” schemes currently 
there is a three year and five year scheme running following an invitation in october 2011 the executive directors are eligible to
join these schemes the nonexecutive directors are not the 2003 saye scheme has expired and a resolution will be put to
shareholders at the annual general meeting to introduce a new scheme the porvair plc saye share option scheme 2014 on
substantially the same terms as the previous scheme

aremunreport p3746 tprf66104p01cln  03032014  1340  page 46 report on the group financial statements
our opinion
in our opinion the group financial statements
• give a true and fair view of the state of the group’s affairs as
at 30 november 2013 and of the group’s profit and cash
flows for the year then ended
• have been properly prepared in accordance with international
financial reporting standards ifrss as adopted by the
european union and
• have been prepared in accordance with the requirements of
the companies act 2006 and article 4 of the ias regulation
this opinion is to be read in the context of what we say below
what we have audited
the group financial statements which are prepared by
porvair plc comprise
• the consolidated balance sheet as at 30 november 2013
• the consolidated income statement and statement of
comprehensive income for the year then ended
• the consolidated statement of changes in equity and
statement of cash flows for the year then ended and
• the notes to the consolidated financial statements which
include a summary of significant accounting policies and
other explanatory information
the financial reporting framework that has been applied in
their preparation comprises applicable law and ifrss as
adopted by the european union
certain disclosures required by the financial reporting
framework have been presented elsewhere in the annual
report and accounts the “annual report” rather than in the
notes to the financial statements these are crossreferenced
from the financial statements and are identified as audited
what an audit of financial statements involves 
we conducted our audit in accordance with international
standards on auditing uk and ireland ‘isas uk  ireland’
an audit involves obtaining evidence about the amounts and
disclosures in the financial statements sufficient to give
reasonable assurance that the financial statements are free
from material misstatement whether caused by fraud or error
this includes an assessment of
• whether the accounting policies are appropriate to the
group’s circumstances and have been consistently applied
and adequately disclosed
• the reasonableness of significant accounting estimates
made by the directors and 
• the overall presentation of the financial statements 
in addition we read all the financial and nonfinancial
information in the annual report to identify material
inconsistencies with the audited group financial statements
and to identify any information that is apparently materially
incorrect based on or materially inconsistent with the
knowledge acquired by us in the course of performing 
the audit if we become aware of any apparent material
misstatements or inconsistencies we consider the 
implications for our report
overview of our audit approach
materiality
we set certain thresholds for materiality these helped 
us to determine the nature timing and extent of our audit
procedures and to evaluate the effect of misstatements 
both individually and on the financial statements as a whole
based on our professional judgement we determined
materiality for the group financial statements as a whole to 
be £370000 which represents approximately 5 of proﬁt
before tax
we agreed with the audit committee that we would report 
to them misstatements identified during our audit above
£18000 as well as misstatements below that amount that 
in our view warranted reporting for qualitative reasons
overview of the scope of our audit
the group is structured along two business lines being
microfiltration and metals filtration and has a number of
centralised functions the group financial statements are a
consolidation of 14 reporting units comprising the group’s
operating businesses within these business lines and the
centralised functions
in establishing the overall approach to the group audit we
determined the type of work that needed to be performed at
the reporting units by us as the group engagement team or
component auditors from other pwc network firms operating
under our instruction where the work was performed by
component auditors we determined the level of involvement
we needed to have in the audit work at those reporting units
to be able to conclude whether sufﬁcient appropriate audit
evidence had been obtained as a basis for our opinion on the
group ﬁnancial statements as a whole 
accordingly of the groups 14 reporting units we identified 7
which are based in the united kingdom and united states of
america and which in our view required an audit of their
complete financial information due to their size specific audit
procedures on certain balances and transactions were
performed at the further 7 reporting units including operations
in the united states of america germany and china this
together with additional procedures performed at the group
level gave us the evidence we needed for our opinion on the
group financial statements as a whole
areas of particular audit focus
in preparing the financial statements the directors made 
a number of subjective judgements for example in respect 
of significant accounting estimates that involved making
assumptions and considering future events that are inherently
uncertain we primarily focused our work in these areas 
by assessing the directors’ judgements against available
evidence forming our own judgements and evaluating 
the disclosures in the financial statements
in our audit we tested and examined information using
sampling and other auditing techniques to the extent we
considered necessary to provide a reasonable basis for us 
to draw conclusions we obtained audit evidence through
testing the effectiveness of controls substantive procedures
or a combination of both

bauditorsgroup p4749 tplayout 1  03032014  1341  page 47 we considered the following areas to be those that required
particular focus in the current year this is not a complete list
of all risks or areas of focus identified by our audit we
discussed these areas of focus with the audit committee
their report on those matters that they considered to be
significant issues in relation to the financial statements is set
out on page 36
going concern
under the listing rules we are required to review the directors’
statement set out on page 30 in relation to going concern
we have nothing to report having performed our review
as noted in the directors’ statement the directors have
concluded that it is appropriate to prepare the group’s
financial statements using the going concern basis of
accounting the going concern basis presumes that the
group has adequate resources to remain in operation and
that the directors intend it to do so for at least one year from
the date the financial statements were signed as part of our
audit we have concluded that the directors’ use of the going
concern basis is appropriate
however because not all future events or conditions can be
predicted these statements are not a guarantee as to the
group’s ability to continue as a going concern
opinion on matter prescribed by the companies act 2006
in our opinion the information given in the strategic report
and the directors’ report for the financial year for which the
group financial statements are prepared is consistent with
the group financial statements
other matters on which we are required to 
report by exception 
adequacy of information and explanations received
under the companies act 2006 we are required to report to
you if in our opinion we have not received all the information
and explanations we require for our audit we have no
exceptions to report arising from this responsibility
directors’ remuneration
under the companies act 2006 we are required to report if 
in our opinion certain disclosures of directors’ remuneration
specified by law have not been made and under the listing
rules we are required to review certain elements of the report
to shareholders by the board on directors’ remuneration we
have no exceptions to report arising from these responsibilities
corporate governance statement
under the listing rules we are required to review the 
part of the corporate governance statement relating to 
the company’s compliance with nine provisions of the uk
corporate governance code ‘the code’ we have 
nothing to report having performed our review
on page 32 of the annual report as required by the code
provision c11 the directors state that they consider the
annual report taken as a whole to be fair balanced and
understandable and provides the information necessary for
members to assess the group’s performance business
model and strategy on page 36 as required by c38 of the
code the audit committee has set out the significant issues
that it considered in relation to the financial statements and
how they were addressed under isas uk  ireland we are
required to report to you if in our opinion
• the statement given by the directors is materially
inconsistent with our knowledge of the group acquired in
the course of performing our audit or
• the section of the annual report describing the work of the
audit committee does not appropriately address matters
communicated by us to the audit committee
we have no exceptions to report arising from this responsibility
other information in the annual report
under isas uk  ireland we are required to report to you if 
in our opinion information in the annual report is
• materially inconsistent with the information in the audited
group financial statements or
• apparently materially incorrect based on or materially
inconsistent with our knowledge of the group acquired in 
the course of performing our audit or
• is otherwise misleading
we have no exceptions to report arising from this responsibility
areas of focus how the scope of our audit
addressed the area of focus
risk of fraud in revenue recognition
auditing standards require that we 
consider this
we focused on this area because of the
potential for misstatement of revenue due 
to the inherent complexities of revenue
recognition
we performed year end sales cut off testing
and we interrogated the accounting system 
to match revenue transactions with cash
receipts to gain assurance over the 
occurrence of revenue transactions
longterm contracts
we focused on this area because of the
judgements required in accounting for the 
long term contracts our focus was on the
judgements around the level of provisions 
for rework costs and other contractual 
provisions and the forecast costs to
complete the contracts refer to note 16 to
the ﬁnancial statements
we tested the reasonableness of the level 
of provisions included in the forecast costs 
against provisions required in similar such
contracts and we challenged management 
on the level of provisions
we tested the calculations of revenue
recognised on these contracts based on 
the work performed to date which we 
agreed to supporting documentation and 
the forecast costs to complete we agreed 
the forecast costs to complete to project 
plans and challenged management on the
preparation of these plans
risk of management override 
of internal controls 
auditing standards require that we 
consider this
we tested manual journal entries we
considered whether there was evidence 
of bias by the directors in the signiﬁcant
accounting estimates and judgements 
relevant to the ﬁnancial statements we also
assessed the overall control environment of 
the group including the arrangements for 
staff to “whistleblow” inappropriate actions
and discussed with senior management 
the possibilities for management override 
of controls

54 porvair plc annual report  accounts 2013
1 summary of signiﬁcant accounting policies 
porvair plc is a public limited company registered and domiciled in the uk and listed on the london stock exchange 
the principal accounting policies applied in the preparation of these consolidated financial statements are set out below
these policies have been consistently applied to all the years presented unless otherwise stated 
basis of preparation
the consolidated financial statements of the group have been prepared in accordance with international financial reporting
standards ifrss as endorsed by the european union the ifrs interpretations committee formerly the international
financial reporting interpretations committee ifric interpretations and those parts of the companies act 2006 applicable
to companies reporting under ifrs the company has elected to prepare its entity accounts in accordance with united
kingdom generally accepted accounting practice “uk gaap” and these are presented on pages 85 to 91
the financial statements have been prepared on a going concern basis and under the historical cost convention as modified
by the recognition of financial assets and financial liabilities including derivative financial instruments at fair value through
profit or loss 
basis of consolidation
the group applies the acquisition method to account for business combinations the consolidated financial statements
incorporate the financial statements of the company and entities controlled by the company its subsidiaries made up to
30 november each year control is achieved where the company has the power to govern the financial and operating policies
of an investee entity so as to obtain benefits from its activities
on acquisition the assets and liabilities and contingent liabilities of a subsidiary are measured at their fair values at the date of
acquisition any excess of the cost of acquisition over the fair values of the identifiable net assets acquired is recognised as
goodwill acquisition related costs are expensed as incurred 
the results of subsidiaries acquired or disposed of during the year are included in the consolidated income statement from
the effective date of acquisition or up to the effective date of disposal as appropriate where necessary adjustments are
made to the financial statements of subsidiaries to bring the accounting policies used into line with those used by the group
any contingent consideration to be transferred by the group is recognised at fair value at the acquisition date subsequent
changes to the fair value of the contingent consideration that is deemed to be an asset or liability is recognised in accordance
with ias 39 either in profit or loss or as a change to other comprehensive income contingent consideration that is classified
as equity is not remeasured and its subsequent settlement is accounted for within equity
all intragroup transactions balances income and expenditures are eliminated on consolidation
use of assumptions and estimates
the preparation of the consolidated financial statements requires management to make judgements estimates and
assumptions that affect the application of policies and reported amounts of assets and liabilities income and expenses 
the estimates and associated assumptions are based on historical experience and various other factors that are believed 
to be reasonable under the circumstances including management’s best knowledge of the amount event or actions 
the results form the basis of making judgements about carrying values of assets and liabilities that are not readily 
apparent from other sources actual results may differ from these estimates
the estimates and underlying assumptions are reviewed on an ongoing basis revisions to accounting estimates are
recognised in the period in which the estimate is revised
material estimates and assumptions are made in particular with regard to establishing uniform depreciation and amortisation
periods for the group goodwill and intangible assets valuation cash flows and discount rate impairment testing
assumptions used in the calculation of share based payments parameters for measuring pension and other provisions and
the likelihood that tax assets can be realised
the group applies the percentage of completion method in accounting for its construction contracts use of the percentage
of completion method requires the group to estimate the construction performed to date as a proportion of the total
construction to be performed estimating the costs to complete is considered to be a material estimate
the group tests annually whether goodwill has suffered any impairment the recoverable amounts of cashgenerating units
have been determined based on valueinuse calculations these calculations require the use of estimates note 10
goodwill
goodwill arising on consolidation represents the excess of the cost of acquisition over the group’s interest in the fair value of
the identifiable assets and liabilities of a subsidiary at the date of acquisition the cost of acquisition includes the fair value of
deferred and contingent consideration
goodwill is recognised as an asset at cost less accumulated impairment losses and reviewed for impairment annually and
more frequently if events or changes in circumstances indicate potential impairment any impairment is recognised
immediately in the income statement and is not subsequently reversed
for the purpose of impairment testing goodwill acquired in a business combination is allocated to each of the cash
generating units that is expected to benefit from the synergies of the combination
on disposal of a subsidiary the attributable amount of goodwill is included in the determination of the profit or loss on
disposal
goodwill arising on acquisitions before the date of transition to ifrss has been retained at the previous uk gaap amounts
subject to being tested for impairment since that date

1 summary of signiﬁcant accounting policies continued
revenue recognition excluding construction contracts
revenue comprises the invoiced value of goods and services supplied net of value added tax and other sales taxes revenue
is recognised when goods are despatched to the customer at which point the risks and rewards of ownership are transferred
revenue from service contracts is recognised on a straightline basis over the contract period
interest income is accrued on a straightline basis by reference to the principal outstanding and the effective interest rate
applicable which is the rate that exactly discounts estimated future cash receipts through the expected life of the financial
asset to that asset’s net carrying amount
construction contracts
where the outcome of a construction contract can be estimated reliably revenue and costs are recognised by reference to
the stage of completion of the contract activity at the balance sheet date this is normally measured by the proportion that
contract costs incurred for work performed to date bear to the estimated total contract costs except where this would not 
be representative of the stage of completion variations in contract work claims and incentive payments are included to the
extent that the amount can be measured reliably and its receipt is considered probable contract costs include costs directly
related to the specific contract and indirect costs attributable to the contract
where the outcome of a construction contract cannot be estimated reliably contract revenue is recognised to the extent of
contract costs incurred where it is probable they will be recoverable contract costs are recognised as expenses in the period
in which they are incurred
when it is probable that total contract costs will exceed total revenue the expected loss is recognised as an expense
immediately
leasing
leases are classified as finance leases whenever the terms of the lease transfer substantially all the risks and rewards of
ownership to the lessee all other leases are classified as operating leases finance lease payments are allocated between the
liability and finance charges so as to achieve a constant rate on the finance balance outstanding the rental obligations net of
finance charges are included in current and noncurrent liabilities the interest element of the finance cost is charged to the
income statement over the lease period so as to produce a constant periodic rate of interest on the remaining balance of the
liability for each period
rentals payable under operating leases are charged to the income statement on a straightline basis over the term of the
relevant lease
foreign currencies
the consolidated financial statements are presented in pounds sterling which is the company’s functional and presentation
currency the group determines the functional currency of each entity based on the primary economic environment in which
the entity operates and items included in the financial statements of each entity are measured using that functional currency
foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of
the transactions or valuation where items are remeasured at each balance sheet date monetary assets and liabilities that
are denominated in foreign currencies are retranslated at the rates prevailing on the balance sheet date foreign exchange
gains and losses resulting from the settlement of such transactions and from the translation at yearend exchange rates of
monetary assets and liabilities denominated in foreign currencies are recognised in the income statement except when
deferred in other comprehensive income as qualifying cash flow hedges
on consolidation the assets and liabilities of the group’s overseas operations borrowings and other currency instruments are
translated at exchange rates prevailing on the balance sheet date income and expense items are translated at the average
exchange rates for the period unless exchange rates fluctuate significantly exchange differences arising if any are classified
as other comprehensive income and transferred to the group’s translation reserve 
goodwill and fair value adjustments arising on the acquisition of a foreign entity are treated as assets and liabilities of the
foreign entity and translated at the closing rate
borrowing costs
all borrowing costs are typically recognised in the income statement in the period in which they are incurred with the
exception of borrowing costs incurred on the arrangement of new facilities which are capitalised and subsequently recognised
in the income statement over the period of the borrowings
government grants
government grants for the development of new products are recognised over the periods necessary to match them with the
related costs and are deducted in reporting the related expense
retirement benefit costs
payments to defined contribution retirement benefit schemes are charged as an expense as they fall due 
for defined benefit retirement schemes the cost of providing benefits is determined using the projected unit credit method
with actuarial valuations being carried out at each balance sheet date actuarial gains and losses are recognised in full in the
period in which they occur they are recognised in the consolidated statement of comprehensive income

adjusted for unrecognised past service cost and as reduced by the fair value of scheme assets 
taxation
the tax expense represents the sum of the current tax and deferred tax
current tax is based on taxable profit for the period taxable profit differs from net profit as reported in the income statement
because it excludes items of income or expense that are taxable or deductible in other periods 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 tax is the tax expected to be payable or recoverable on differences between the carrying amounts of assets 
and liabilities in the financial statements and the corresponding tax bases used in the computation of taxable profit and is
accounted for using the balance sheet liability method deferred tax liabilities are generally recognised for all taxable
temporary differences and deferred tax assets are recognised to the extent that it is probable that taxable profits will be
available against which deductible temporary differences can be utilised such assets and liabilities are not recognised if the
temporary difference arises from goodwill or from the initial recognition other than a business combination of other assets
and liabilities in a transaction that affects neither the tax profit nor the accounting profit
deferred tax liabilities are recognised for taxable temporary differences arising on investments in subsidiaries and associates
except where the group is able to control the reversal of the temporary difference and it is probable that the temporary
difference will not reverse in the foreseeable future
the carrying amount of deferred tax assets is reviewed at each balance sheet date and reduced to the extent that it is no
longer probable that sufficient taxable profits will be available to allow all or part of the asset to be recovered
deferred tax is calculated at the tax rates which have been enacted or substantively enacted by the balance sheet date 
and are expected to apply in the period when the liability is settled or the asset is realised deferred tax is recognised in the
income statement except when it relates to items recognised directly to other comprehensive income or directly to equity 
in this case the deferred tax is also recognised in other comprehensive income or directly in equity respectively
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
property plant and equipment
property plant and equipment for use in the production or supply of goods or services or for administrative purposes are
stated in the balance sheet at their cost less any subsequent accumulated depreciation and subsequent accumulated
impairment losses 
property plant and equipment in the course of construction for production or administrative purposes are carried at cost less
any recognised impairment loss cost includes professional fees and for qualifying assets borrowing costs capitalised in
accordance with the group’s accounting policy depreciation for these assets on the same basis as other assets
commences when the assets are ready for their intended use
depreciation is charged so as to write off the cost of assets other than assets under construction over their estimated useful
lives using the straight line method on the following bases
buildings                                                25 – 3
plant machinery and equipment            10 – 33
freehold land is not depreciated
assets held under finance leases are depreciated over their expected useful lives on the same basis as owned assets or
where shorter over the term of the relevant lease
the gain or loss arising on the disposal or retirement of an asset is determined as the difference between the sales proceeds
and the carrying amount of the assets and is recognised in the income statement
the assets’ residual values and useful lives are reviewed and adjusted if appropriate at the end of each reporting period

internally generated intangible assets – research and development expenditure
expenditure on research activities is recognised as an expense in the period in which it is incurred
an internally generated intangible asset arising from the group’s product development expenditure is recognised only if all of
the following criteria are demonstrable
• the technical feasibility of completing the intangible asset so that it will be available for use or sale
• the intention to complete the intangible asset and use or sell it
• the ability to use the intangible asset or to sell it 
• the way in which the intangible asset will generate probable future economic benefits
• the availability of adequate technical financial and other resources to complete the development and to use or sell the
intangible asset and  
• the ability to measure reliably the expenditure attributable to the intangible asset during its development 
internally generated intangible assets are valued at cost and held at cost less accumulated amortisation and impairment
losses which is recognised as an expense on a straight line basis over their estimated useful lives useful life is determined
with reference to estimated product life in the industry in which the expenditure has been incurred useful life of the group’s
development expenditure is currently between 3 and 10 years amortisation of development expenditure commences when
development has been completed to management satisfaction and the related project is ready for its intended use where no
internally generated intangible asset can be recognised development expenditure is recognised as an expense in the period
in which it is incurred
patents trademarks and knowhow
patents trademarks and knowhow purchased as part of an acquisition where there are expected future economic benefits
are initially measured at fair value and amortised over their estimated useful lives of 35 years
software
software costs are classified as intangible fixed assets and measured initially at purchase cost amortisation is charged on a
straight line basis over their estimated useful lives of 35 years
impairment of property plant and equipment and intangible assets 
the group reviews annually the carrying amounts of its property plant and equipment and intangible assets to determine
whether there is any indication that those assets have suffered an impairment loss if any such indication exists the
recoverable amount of the asset is estimated in order to determine the extent of the impairment loss if any for the purposes
of assessing impairment assets are grouped at the lowest levels for which there are separately identifiable cash flows cash
generating units
recoverable amount is the higher of fair value less costs to sell and value in use in assessing value in use the estimated
future cash flows are discounted to their present value using a pretax discount rate that reflects current market assessments
of the time value of money and the risks specific to the asset for which the estimates of future cash flows have not been
adjusted if the recoverable amount of an asset or cash generating unit is estimated to be less than its carrying amount the
carrying amount of the asset or cash generating unit is reduced to its recoverable amount an impairment loss is recognised
as an expense immediately
when an impairment loss subsequently reverses the carrying amount of the asset or cash generating unit other than
goodwill is increased to the revised estimate of its recoverable amount but so that the increased carrying amount does not
exceed the carrying amount that would have been determined had no impairment loss been recognised for the asset or cash
generating unit in prior years a reversal of an impairment loss is recognised in the income statement immediately
inventories
inventories are stated at the lower of cost and net realisable value cost comprises direct materials and where applicable
direct labour costs and those overheads that have been incurred in bringing the inventories to their present location and
condition cost is calculated using the weighted average method net realisable value represents the estimated selling price
less all estimated costs of completion and costs to be incurred in marketing selling and distribution where necessary
provision is made for obsolete slow moving and defective inventories
loans and receivables
loans and receivables are nonderivative financial assets with fixed or determinable payments that are not quoted in an active
market they are included in current assets except for those with maturities greater than 12 months after the balance sheet
date these are classified as noncurrent assets loans are classified as “other receivables” in the balance sheet
trade receivables
trade receivables are recognised initially at fair value and subsequently held at amortised cost a provision for impairment 
of trade receivables is established when there is objective evidence that the group will not be able to collect all amounts 
due according to the original terms of receivables significant financial difficulties of the debtor and default or delinquency 
in payments when credit control procedures have been applied are indicators an impairment may be required the amount 
of the provision is the difference between the asset’s carrying amount and the present value of the estimated future cash
flows discounted at the effective interest rate the amount of the provision is recognised in the income statement within
administrative expenses when a trade receivable is uncollectible it is written off to the provision for impairment subsequent
recoveries of amounts previously written off are credited against administrative expenses in the income statement

cash and cash equivalents
in the consolidated statement of cash flows cash and cash equivalents includes cash in hand deposits held at call with
banks other shortterm highly liquid investments with original maturities of three months or less and bank overdrafts in the
consolidated balance sheet bank overdrafts are shown within borrowings in current liabilities
bank borrowings
interest bearing bank loans and overdrafts are recorded at the proceeds received net of direct issue costs finance charges
including premiums payable on settlement or redemption and direct issue costs are accounted for on an accruals basis in the
income statement using the effective interest method and are added to the carrying amount of the instrument to the extent
that they are not settled in the period in which they arise
trade payables
trade payables are not interest bearing and are initially recognised at fair value and subsequently held at amortised cost
equity instruments
ordinary shares are classified as equity equity instruments issued by the company are recorded at the proceeds received
net of direct issue costs
derivative financial instruments and hedge accounting
the group’s activities expose it primarily to the financial risks of changes in foreign currency exchange rates and interest rates 
the group uses foreign exchange forward contracts and interest rate swap agreements to hedge these exposures the
group does not use derivative financial instruments for speculative purposes
the use of financial derivatives is governed by the group’s policies approved by the board of directors which provides written
principles on the use of financial derivatives
derivatives are initially recognised at fair value on the date a derivative contract is entered into and are subsequently
remeasured at their fair value the method of recognising the resulting gain or loss depends on whether the derivative is
designated as a hedging instrument and if so the nature of the item being hedged the group designates certain derivatives
as cash flow hedges
for cash flow hedges the group documents at the inception of the transaction the relationship between hedging instruments
and hedged items as well as its risk management objectives and strategy for undertaking various hedging transactions the
group also documents its assessment both at hedge inception and on an ongoing basis of whether the derivatives that are
used in hedging transactions are highly effective in offsetting changes in fair values or cash flows of hedged items 
the effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges is
recognised in equity the gain or loss relating to the ineffective portion is recognised immediately in the income statement
amounts accumulated in equity are recycled in the income statement in the periods when the hedged item affects profit or
loss for example when the forecast sale that is hedged takes place the gain or loss relating to the effective portion of
interest rate swaps hedging variable rate borrowings is recognised in the income statement
when a hedging instrument expires or is sold or when a hedge no longer meets the criteria for hedge accounting any
cumulative gain or loss existing in equity at that time remains in equity and is recognised when the forecast transaction is
ultimately recognised in the income statement when a forecast transaction is no longer expected to occur the cumulative
gain or loss that was reported in equity is immediately transferred to the income statement
changes in the fair value of derivative financial instruments that do not qualify for hedge accounting are recognised in the
income statement as they arise
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 host contracts and the host contracts are not carried at fair value
with unrealised gains or losses reported in the income statement
provisions
provisions have been made for future dilapidation costs on leased property these provisions are the directors’ best estimates
as the actual costs and timing of future cash flows are dependent on future events any difference between expectations and
the actual future liability will be accounted for in the period when such determination is made
where the impact of discounting is material the group discounts at its weighted average cost of capital unless some other
rate is more appropriate in the circumstances
share based payments
the group has applied the requirements of ifrs 2 “share based payment” in accordance with the transitional provisions
ifrs 2 has been applied to all grants of equity instruments after 7 november 2002 that were unvested as of 1 january 2005
the group issues equity settled share based payments to certain employees equity settled share based payments are
measured at fair value at the date of grant the fair value determined at the grant date of the equity settled share based
payments is expensed on a straight line basis over the vesting period based on the group’s estimate of shares that will
eventually vest the charge is then credited back to reserves
nonmarket performance and service conditions are included in assumptions about the number of options that are expected
to vest

at each balance sheet date the group revises its estimates of the number of options that are expected to vest it recognises
the impact of the revision to original estimates if any in the income statement with a corresponding adjustment to equity
fair value is measured by use of a blackscholes model the expected life used in the model has been adjusted based on
management’s best estimate for the effects of nontransferability exercise restrictions and behavioural considerations
exceptional items
the group presents certain items as “exceptional” these are material items which derive from events or transactions that fall
within the group’s ordinary activities and which by virtue of their size nature or incidence need to be separately disclosed to
enable an understanding of the group’s underlying financial performance examples of items include but are not limited to
acquisition costs disposals or restructuring of a significant part of an operating segment impairment events and litigation
claims by or against the group
segment reporting
an operating segment is a component of an entity that engages in business activities from which it may earn revenues and
incur expenses including revenues and expenses relating to transactions with other components of the same entity an
operating segment’s operating results are regularly reviewed by the entity’s chief operating decision maker to make decisions
about resources to be allocated to the segment and assess its performance and for which discrete financial information is
available operating segments are aggregated into reporting segments where they share similar economic characteristics 
as a result of the nature of the products sold or the services provided the production processes used to manufacture the
products the type of customer for the products and services and the methods used to distribute the products or provide 
the services
dividend distribution
dividend distribution to the company’s shareholders is recognised as a liability in the group’s financial statements in the
period in which the dividends are approved by the company’s shareholders
new standards amendments and interpretations
a standards amendments and interpretations effective for the first time in the year ended 30 november 2013
• amendment to ias 12 ‘income taxes’ on deferred tax and
• amendment to ias 1 ‘financial statement presentation’ regarding other comprehensive income
none of these have had any impact on the reported results of the group
b standards amendments and interpretations that are not yet effective and have not been early adopted
• amendment to ias 19 ‘employee benefits’
• amendment to ifrs 1 ‘first time adoption’ on government loans
• amendment to ifrs 7 ‘financial instruments disclosures’ on asset and liability offsetting
• amendment to ifrss 10 11 and 12 on transition guidance
• annual improvements 2011
• ifrs 10 ‘consolidated financial statements’
• ifrs 11 ‘joint arrangements’
• ifrs 12 ‘disclosures of interests in other entities’

• amendment to ias 32 ‘financial instruments presentation’ on asset and liability offsetting
• amendments to ifrss 10 and 12 and ias 27 on consolidation for investment entities
• amendment to ias 36 ‘impairment of assets’ on recoverable amount disclosures
• amendment to ias 39 ‘financial instruments recognition and measurement’ on novation of derivatives
• ifric 21 ‘levies’ and
• ifrs 9 ‘financial instruments’
the directors do not anticipate that the adoption of these standards amendments and interpretations where relevant in future
periods will have a material impact on the group’s financial statements other than the adoption of ias 19 ‘employee benefits’
ias 19 ‘employee benefits’ was amended in june 2011 and is effective for periods beginning on or after 1 january 2013 the
impact will be as follows to immediately recognise all past service costs and to replace interest cost and expected return on
plan assets with a net interest amount that is calculated by applying the discount rate to the net defined benefit liability the
group has calculated that if ias 19 revised 2011 had been adopted early for the year ended 30 november 2013 it would
have resulted in an additional charge of £210000

these assumptions have been used for the analysis of each operation within the operating segment management determined
budgeted gross margin based on past performance and its expectations for the development in the group’s markets the
average growth rates used are consistent with past experience and market expectations the discount rates used are pretax
and reflect specific risks relating to the relevant segments
based on the results of the current period impairment review no impairment charges have been recognised by the group in
the year ended 30 november 2013 having assessed the anticipated future cash flows the directors do not currently foresee
any reasonable changes in assumptions that would lead to such an impairment charge in the year ended 30 november 2013

there is no difference between the fair value of trade and other receivables and their carrying value
credit risk in relation to trade receivables
the group has a diverse customer base both geographically and in the number of industries in which it operates 
there is credit risk associated with a decline in a particular industry or geographic region to offset this risk the group has
implemented policies that require appropriate credit checks to be performed on significant potential customers before 
sales are made customer orders are checked against preset criteria before acceptance and credit control procedures are
applied letters of credit and payments in advance are obtained from customers as appropriate
the group does not hold security over its receivables so was exposed to credit risk in respect of the net trade receivables
balance of £11568000 2012 £10884000 management believe the credit quality of trade receivables which are within the
group’s typical payment terms of between 30 and 90 days and which are less than 3 months overdue are good with
£2473000 2012 £1388000 being past due but not impaired at the year end of which £2029000 2012 £1070000 are

a number of employees in the uk the pension scheme is financed through a separate trust fund administered by trustees
with an independent chairman the plan was closed to new entrants in october 2001

available and rely as little as possible on entity specific estimates if all significant inputs required to fair value an instrument are
observable the instrument is included in level 2

report on the parent company financial statements
our opinion
in our opinion the parent company financial statements
• give a true and fair view of the state of the parent company’s
affairs as at 30 november 2013 and of its cash flows for the
year then ended
• have been properly prepared in accordance with united
kingdom generally accepted accounting practice and
• have been prepared in accordance with the requirements 
of the companies act 2006
this opinion is to be read in the context of what we say below
what we have audited
the parent company financial statements which are
prepared by porvair plc comprise
• the parent company balance sheet as at 30 november 2013
• the parent company reconciliation of movements in
shareholders’ funds and
• the notes to the parent company financial statements which
include a summary of significant accounting policies and
other explanatory information
the financial reporting framework that has been applied in their
preparation comprises applicable law and united kingdom
accounting standards united kingdom generally accepted
accounting practice
in applying the financial reporting framework the directors
have made a number of subjective judgements for example
in respect of significant accounting estimates in making such
estimates they have made assumptions and considered
future events
certain disclosures required by the financial reporting
framework have been presented elsewhere in the annual
report rather than in the notes to the financial statements
these are crossreferenced from the financial statements and
are identified as audited

1 summary of signiﬁcant accounting policies
these financial statements have been prepared on a going concern basis under the historical cost convention and in
accordance with the companies act 2006 and applicable uk accounting standards a summary of the more important
accounting policies is set out below which have been applied on a consistent basis with the previous year except where noted
tangible fixed assets 
tangible fixed assets are capitalised at cost and are depreciated by equal annual amounts over their estimated useful lives
annual depreciation rates are 10 to 3333 straight line for plant machinery and equipment 
fixed asset investments
investments held as fixed assets are stated at cost less provision for impairment in value 
impairment of assets
assets are regularly reviewed to confirm their carrying values where the expected realisable value is lower than the book value
the excess of book value is charged to the profit and loss account during the period 
patents and trademarks
all expenditure on the registration renewal and maintenance of patents and trademarks is expensed as incurred
foreign exchange
monetary assets and liabilities denominated in foreign currencies are translated into sterling at the rates of exchange ruling at the
end of the financial year 
exchange differences arising on retranslation of nonmonetary assets and liabilities are recognised directly to the exchange
reserve all other foreign exchange differences are taken to the profit and loss account in the year in which they arise
deferred taxation
the charge for tax is based on the profit for the year and takes into account tax deferred or accelerated because of timing
differences between the treatment of certain items for accounting and tax purposes full provision is made for deferred tax
resulting from timing differences between profits computed for tax purposes and profits stated in the financial statements to the
extent that there is an obligation to pay more tax in the future as a result of the reversal of those timing differences deferred tax
assets are recognised to the extent that they are expected to be recoverable and are measured on a nondiscounted basis
based on tax rates and laws enacted or substantively enacted at the balance sheet date
pensions
pension costs for defined benefit and defined contribution schemes are charged to the profit and loss account as incurred
the company participates in the group’s defined benefit pension scheme which is closed to new members the porvair plc
pension and death benefit plan the company includes only the cost of its contributions to the scheme in its profit and loss
account for the year because the structure of the scheme is such that it does not enable any individual group company to
identify its share of the assets and liabilities of the scheme
share based payments
the company has applied the requirements of frs 20 “share based payments” in accordance with the transitional provisions
frs 20 has been applied to all grants of equity instruments after 7 november 2002 that were unvested as of 1 january 2005
where the parent company has granted rights over its equity instruments to the employees of subsidiary companies there is a
corresponding increase recognised in the investment in subsidiary undertakings in those years
the company issues equity settled share based payments to certain employees equity settled share based payments are
measured at fair value at the date of grant the fair value determined at the grant date of the equity settled share based
payments is expensed on a straight line basis over the vesting period based on the company’s estimate of shares that will
eventually vest the charge is then credited back to reserves
at each balance sheet date the company revises its estimates of the number of share options that are expected to vest it
recognises the impact of the revisions to original estimates if any in the profit and loss account or if relating to a subsidiary
undertaking in investment in subsidiary undertakings with a corresponding adjustment to equity
fair value is measured by use of a blackscholes model the expected life used in the model has been adjusted based on
management’s best estimate for the effects of nontransferability exercise restrictions and behavioural considerations
operating leases
rentals payable under operating leases are charged to the profit and loss account on a straight line basis over the term of the
relevant lease
borrowing costs
all borrowing costs are typically recognised in the profit and loss account in the period in which they are incurred borrowing
costs incurred in the arrangement of new facilities are capitalised and subsequently recognised in the profit and loss account
over the period of the borrowings
related party transactions

not to disclose transactions and balances with wholly owned subsidiaries
