pure wafer at a glance
the company has an established 
track record two of the worlds most 
advanced wafer reclaim facilities and a 
blue chip customer base that includes 
the majority of the worlds largest 
semiconductor manufacturers and 
independent foundries as a business 
partner  pure wafer works with its 
customers to design and develop a 
service that delivers reclaimed wafers 
to the exacting specifications and high 
standards required by today’s leading 
semiconductor manufacturers 
our history
pure wafer was established in 2000 by 
a management team widely experienced 
in the semiconductor industry with the 
backing of strategic investment from 
venture capital and industry partners
the group floated on aim in december 
2004 and february 2007 pure wafer 
completed the acquisition of a wafer 
reclaim facility in arizona us
our facilities
the uk business operates from a state of 
the art purpose built facility situated in 
a technology park in swansea wales and 
is the most advanced plant of its kind in 
europe the size of the facility is in excess 
of 4500m
2
 and includes over 2000m
2
 of 
production cleanrooms
the facility in prescott arizona was 
constructed in 1997 and has received 
in excess of 50m of investment since 
then the highvolume hightech fab 
was originally designed for 200mm and 
smaller diameter wafer reclaim services 
but following the acquisition by pure 
wafer in 2007 capability to reclaim 
300mm wafers has been installed
we have installed the latest generation 
of tools available on the market with 
the most advanced equipment as used 
by integrated chip ic and prime silicon 
producers with the highest technical 
specifications we are positioned to offer 
the most effective wafer reclaim services 
to our customers with minimal silicon 
removal this enables our customers to 
maximise the number of times a test 
wafer can be reclaimed
pure wafer is a worldwide leader in the provision of 300mm 
wafer reclaim services these services enable semiconductor 
manufacturers to gain efficiencies through the increased use 
of silicon test wafers within their production processes annual report and accounts 2011  pure wafer plc       3
our process
at pure wafer our process for reclaiming 
test wafers involves the following key 
stages
inspection of the wafers for defects •	
and classification by type of 
contaminant to be removed
submersion in a precise mix of •	
chemicals appropriate to remove the 
contaminant 
assessment of flatness and •	
correction of defects using pure 
wafer’s advanced polishing processes
cleaning and drying •	
final quality inspection and •	
packaging for return to the customer
wafer reclaim
during the many stages of the manufacturing process of 
semiconductors large quantities of test wafers are used to check 
the accurate calibration of equipment these test wafers are a key 
consumable in the manufacture of semiconductors and the ability 
to reclaim them through pure wafer’s advanced process provides 
manufacturers with the opportunity to reduce costs
the semiconductor industry transition to 300mm wafers in now 
well advanced in order for manufacturers to continue to increase 
functionality at a reduced cost the industry has sought to increase 
the size of wafers on which semiconductors are manufactured 
300mm wafer processing now represents the fastest growing area 
of the semiconductor industry
however  wafer reclaim is a highly specialised and technically 
sophisticated process only a few companies worldwide are 
able to meet the exacting standards required by semiconductor 
manufacturers for the reclaim of 300mm wafers of which pure 
wafer is one 4       pure wafer plc   annual report and accounts 2011
chairman’s statement
introduction
the year to 30 june 2011 saw the 
semiconductor industry move from 
recovery to growth with pure wafer 
continuing to benefit from the additional 
volume business from all geographical 
areas in which we trade and with all 
customers across the various sectors of 
the industry 
the industry growth in general and the 
projected increasing worldwide demand 
for hand held devices and tablets also 
prompted some of our major customers 
to announce extensive capital expenditure 
plans for new 300mm manufacturing 
facilities coming on line between now and 
2014 both in asia and north america 
these announcements and actions give 
exciting long term prospects for pure 
wafer 
during the financial year as volume 
demand strengthened and the confidence 
in a period of sustained growth returned 
there has been an acceptance of selling 
price increases across the customer 
base and an acknowledgement that 
the low prices of previous periods were 
unsustainable for the industry the 
group has therefore been successful in 
implementing price increases across its 
customer base
the unfortunate events in japan following 
the tsunami in february resulted in 
additional business for pure wafer in 
our fourth quarter as our customers 
looked to ensure that their reclaim wafer 
supply was maintained as our japanese 
competitors struggled to maintain their 
service
during the financial year we saw the pure 
wafer solar panel business successfully 
achieve full accreditation under the 
microgeneration certification scheme 
mcs for all our solar products and 
our solar installations this enables 
our customers to take advantage of 
the uk government’s feedintariff the 
accreditation of our products provides us 
with a strong platform on which to build 
financial results

• operating loss 38m 2010 68m
• pretax loss 51m 2010 80m
• basic loss per share 36c 2010 loss 
per share 51c 
the results show significant improvement 
on prior years and the board is 
encouraged by the actions of the 
management team during the period to 
take advantage of the market conditions 
to maximise revenue and to continue 
reducing costs across all sectors of the 
business 
group funding
during the period we successfully 
completed negotiations with our bank 
and asset funders of a further financial 
restructuring package which will assist 
the management of our working capital 
requirement arising from the increased 
volumes of wafer reclaim and the 
potential growth in our solar business 
the financial agreements comprise a 
further 6 months of capital payments 
holiday on the asset based debts and a 
rescheduling of the capital repayments 
over a 42 month period commencing on 
1st january 2012 and concluding by 30th 
june 2015 the agreement also includes 
an increased bank overdraft facility of up 
to £17million 27million 
the company’s existing bank debt 
continues to be repaid in accordance 
with the original restructuring agreement 
completed in august 2009
the latest financial restructuring 
agreement further demonstrates the 
commitment that the bank and asset 
funders have to pure wafer and shows 
a confidence in the recovery of the 
business and i would like to thank them 
for their support
management
i would like to thank the entire team for 
their support and efforts during a year 
in which activity levels increased and our 
solar products were accredited
outlook
the current period has commenced 
strongly with a continuation of high 
volumes enjoyed during our fourth 
quarter it is particularly pleasing that 
high and stable volumes are being seen 
from our customers in all geographical 
regions this together with the 300mm 
manufacturing facilities currently under 
construction by the semiconductor 
industry and in some cases nearing 
completion gives an optimistic long term 
outlook
on the flip side the worldwide fear of a 
second recession due to the uncertainty 
in the financial markets and the effect 
of this on consumer confidence has 
the semiconductor industry’s move from recovery 
to growth has been reflected in our results annual report and accounts 2011  pure wafer plc       5
prompted the industry to consider its 
levels of inventory many industry analysts 
are predicting a short term industry 
slowdown during our second quarter 
with full production returning during 
the beginning of the second half of our 
financial year 
the launch of our solar products is a 
very exciting time for pure wafer because 
we believe that the renewable energy 
market has massive potential growth both 
globally and significantly here in the uk 
underpinned by the introduction of the 
government backed feedintariff in april 
2010 the 2012 financial year has started 
well following successful accreditation 
of our products in 2011 a number of 
solar installations have been completed 
our order book is building with a mix 
of domestic and large commercial 
installations we have been successful 
in being awarded a contract for a local 
community housing scheme for rooftop 
solar pv systems with a potential value of 
up to £1million and are well placed to win 
other major solar contracts in the public 
sector all for completion this forthcoming 
financial year 
these factors together with our financial 
restructuring providing additional working 
capital gives pure wafer a strong 
foundation on which to move forward

chief executive’s review
operational review
the financial year to june 2011 continued 
the upward trend that we enjoyed during 
last financial year with continued growth 
in volumes across all diameter sizes of 
wafers both in swansea and prescott as 
the semiconductor industry continued to 
grow 
volume sales for the group grew during 
the period with 300mm wafer reclaim 
up by 27 when compared to the prior 
year  and 200mm wafer reclaim up 24 
whilst we were encouraged by the volume 
sales for the first half of the year the 
second half of the year saw even stronger 
growth with increases on 300mm of 22 
when compared to the first half
a significant challenge for our operational 
teams was to process the additional 
and growing volumes whilst maintaining 
the cost reductions and benefits gained 
during the prior periods in a market 
where our suppliers were requesting 
price increases for the majority of our 
consumable items i am very pleased to 
report that we managed to build on our 
past successes and reduce costs per 
wafer even further by 10 compared with 
the prior financial year  these cost savings 
were in part due to economies of scale 
but also due to successful engineering 
activities to reduce consumable usage 
and costs within our processes all 
without affecting the quality of the 
group’s product offering
the processing of the increased volumes 
was also achieved with a modest increase 
in headcount and thus pure wafer 
benefited from cost efficiencies as record 
levels of productivity were achieved in 
both the swansea and prescott facilities 
i would like to thank all our employees 
for their hard work and support during 
the year enabling pure wafer to continue 
to trade competitively throughout this 
period

swansea site uk
the swansea site continued to see 
growing demand from our european and 
asian customers during the period with 
300mm volume sales growing by 28 
compared to the prior year and 200mm 
volume sales increasing by 15 the 
second half of the financial year showed 
strong growth compared to the first half 
for our 300mm volumes with a 26 
increase whilst the 200mm volumes 
dropped by 20 as one of our major 
customers completed their transition 
from 200mm to 300mm manufacturing 
prescott site arizona usa
the prescott arizona facility is now 
running large scale 300mm production 
and has made significant progress in 
increasing our 300mm wafer reclaim 
market share in the us where we are 
actively engaged with every major 
300mm integrated chip manufacturer 
who have a manufacturing presence in 
the us volume sales grew for the period 
with 300mm up by 23 when compared 
to the prior year and 200mm up by 29 
with the quality of our offering equal to 
the stringent requirements of our blue 
chip customer base we envisage further 
significant market gains
with the group’s current installed 
capacity for 300mm and smaller 
diameter wafers at pure wafer’s high 
quality facilities in swansea and prescott 
arizona together with the reduced cost 
per wafer  the board believe that the 
company is well placed for future growth
the increased volume sales has resulted in record 
levels of productivity and a further decrease in our 
costs per unit annual report and accounts 2011  pure wafer plc       7
solar pv
this was an exciting year for the pure 
wafer solar panel business during which 
we successfully achieved full accreditation 
of our solar products and our solar 
installations under the microgeneration 
certification scheme mcs following 
delays in the accreditation process due 
to a lack of testing facilities here in the 
uk with the mcs accreditation any 
installation by pure wafer or with pure 
wafer products enables our customers 
to take advantage of the government 
feedintariff we were also able to bed 
in our manufacturing lines the interest 
and uptake of our products has been 
strong and whilst revenue generation 
during this period has been negligible 
the foundations are now in place for 
substantial growth with the solar pv 
market being one of the fastest growing 
sectors in the uk currently we see this 
as a exciting addition to our portfolio 
of products and are confident that it 
will provide significant revenue and 
profitability to the group

reporting currency
this is the second year we have reported 
in dollars the currency of the industry 
we are in this alignment of functional 
currency and reporting currency allows 
us to produce accounts that are clearer 
and more transparent without the need 
for the large and numerous adjustments 
required at the year end to deal with 
the difference between functional and 
reporting currencies

2010 112m for the group show an 
increase on the prior year this increase 
has been driven principally by rising staff 
costs
loss before tax
the loss before tax was 51m 2010 
80m 
foreign exchange
we continue to convert as much of the 
cost base as possible to us dollars in 
order to provide a natural hedge against 
the us dollar revenue streams

dividends
the directors do not recommend the payment of a dividend 2010 nil
risks and uncertainties 
there are a number of potential risks and uncertainties which could have a material impact on the company’s longterm 
performance
market risk
volumes – in the current climate there is a risk that sales volumes may decrease if the industry growth is not sustained leading to 
a reduction in market prices as our competitors compete for existing business we mitigate the risk by maintaining our standards of 
quality and endeavouring to qualify to provide wafer reclaim services to as many of the major semiconductor manufacturers as we 
can
price – competitive pressures create a risk that the market price for wafer reclaim services will fall affecting our gross margin 
we mitigate this risk by understanding the production cost for each wafer and only tendering for work at rates that will achieve an 
acceptable return
credit risk
the group offers shortterm credit to customers and there is a risk that customers will default on payments for services provided 
the group manages the risk by trading with a wide range of customers in diverse geographical locations and monitoring the 
creditworthiness of customers both before offering credit terms and during their relationship with pure wafer 
treasury risk
interest rate – the group’s borrowings include variable rate term loans and fixed rate finance leases we mitigate the risk associated 
with our variable rate loans by entering into interest rate swaps 
competitor risk
new entrants – the high level of investment required and the related cost of capital makes this unlikely in the current market 
conditions
technology risk
as the group operates in a technology sector there is a risk that the process could be superseded and new capital investment 
required however the board feels that this is extremely unlikely in the current market and based on available knowledge of new 
producttechnology developments
capital structure

above its forecast cash requirement which will allow it to manage its business risks successfully despite the current uncertain 
outlook 
the directors have assessed the balance sheet and likely future cash flows of the company and group at the date of approving the 
accounts this review considered detailed forecasts for the period to 30 june 2013 on this basis the directors have concluded that it 
is appropriate to prepare the financial statements on a going concern basis
the key sensitivity in the forecasts includes the achievement of increased sales volumes the business has experienced an upturn in 
demand for its services and the directors believe that this will be sustained sales prices are assumed to remain largely unchanged 
after making enquiries the directors have a reasonable expectation that the group and the company have adequate resources 
to continue in operational existence for the foreseeable future for this reason they continue to adopt the going concern basis in 
preparing the annual report and financial statements

audit report this review considered detailed forecasts for the period to 30 june 2013 on this basis the directors have concluded 
that it is appropriate to prepare the financial statements on a going concern basis  
the key sensitivity in the forecasts includes the achievement of increased sales volumes the business has experienced an upturn in 
demand for its services and the directors believe that this will be sustained sales prices are assumed to remain largely unchanged  
after making enquiries the directors have a reasonable expectation that the group and the company have adequate resources 
to continue in operational existence for the foreseeable future for this reason they continue to adopt the going concern basis in 
preparing the annual report and financial statements

2 summary of significant accounting policies continued
going concern continued
basis of consolidation
the consolidated financial statements comprise pure wafer plc the company and its subsidiary undertakings pure wafer 
international limited and pure wafer  inc
subsidiaries are those entities controlled by the company control exists when the company has the power to govern the financial 
and operating policies of an enterprise so as to obtain benefits from its activities the financial statements of subsidiaries are 
included in the consolidated financial statements from the date that control commences until the date that control ceases
the purchase method of accounting is used to account for the acquisition of subsidiaries the cost of an acquisition is measured 
at the fair value of the consideration plus costs directly attributable to the acquisition the excess of the cost of the acquisition 
over the group’s share of the fair value of the net identifiable assets of the subsidiary acquired is recorded as goodwill intragroup 
transactions balances and unrealised gains on transactions between group companies are eliminated unrealised losses are also 
eliminated unless costs cannot be recovered where necessary accounting policies of subsidiaries have been changed to ensure 
consistency with the policies adopted by the group
segmental reporting
operational segments are reported in a manner consistent with the internal reporting provided to the chief operating decision 
maker  the chief operating decision maker  who is responsible for allocating resources and assessing the performance of operating 
segments has been identified as the board members that make strategic decisions the solar business is not deemed to be a 
separate segment for the purposes of the 2011 results as it did not commence commercial trading until after the yearend
foreign currency
items included in the financial statements of each of the group’s entities are measured using the currency of the primary 
economic environment in which the entity operates the functional currency for the group’s two operating subsidiaries pure wafer 
international limited and pure wafer inc this has been determined to be usd pure wafer plc is also reported in usd
any translation differences that have arisen since 1 july 2006 are presented as a separate component of equity as permitted by 
ifrs 1 any differences prior to this date are not included in this separate component of equity 
foreign currency transactions are initially recorded at the exchange rate ruling at the date of the transaction foreign exchange gains 
and losses resulting from the settlement of such transactions and from the translation at exchange rates ruling at the balance sheet 
date of monetary assets and liabilities denominated in foreign currencies are recognised in the income statement except when 
deferred in equity as qualifying net investment hedges
financial instruments
financial assets and financial liabilities are recognised when the group becomes a party to the contractual provisions of the 
relevant instrument financial assets are derecognised when the rights to receive benefits have expired or been transferred and the 
group has transferred substantially all risks and rewards of ownership financial liabilities are derecognised when the obligation is 
extinguished
nonderivative financial assets are classified as either receivables or cash and cash equivalents they are stated at amortised 
cost using the effective interest method subject to reduction for allowances for estimated irrecoverable amounts 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 those receivables the amount of the provision is the difference between the asset’s carrying 
amount and the present value of estimated future cash flows and is recognised in the income statement for interestbearing 
assets their carrying value includes accrued interest receivable
cash and cash equivalents include cash in hand and deposits held on call together with other shortterm highly liquid investments 
nonderivative financial liabilities are stated at amortised cost using the effective interest method for borrowings their carrying 
value includes accrued interest payable as well as any unamortised issue costs
the group transacts derivative financial instruments to manage the underlying exposure to foreign exchange and interest rate risks 
the group does not transact derivative financial instruments for trading purposes however  as the group has decided not to hedge 
account for its derivative financial instruments as permitted under ias 39 they are accounted for through the income statement 
derivative financial assets and liabilities are stated at fair value which includes accrued interest receivable and payable where 
relevant changes in fair values are recognised in the income statement in the period in which they arise
financial liabilities and issue costs
all borrowings are initially stated at the fair value of the consideration received after deduction of issue costs issue costs are 
charged as a finance charge to the income statement on a constant yield basis over the term of the borrowings 
revenue recognition
revenue which represents the value of goods and services supplied excluding value added tax and trade discounts is recognised 
on completion of the service or despatch of goods sold in respect of the provision of wafer reclaim services the service is deemed 
to be complete at the point that the wafers are despatched for return to the customer in the case of solar products revenue will be 
recognised when installation works at customer sites have been completed

provisions
a provision is recognised in the balance sheet when the group has a legal or constructive obligation as a result of a past event where 
it is more likely than not that an outflow of resources will be required to settle that obligation and a reliable estimate of the amount 
can be made
a provision for restructuring is recognised when the group has approved a detailed and formal restructuring plan and the 
restructuring has either commenced or has been publicly announced future operating losses are not provided for 
where there are a number of similar obligations the likelihood that an outflow will be required in settlement is determined by 
considering the class of obligations as a whole a provision is recognised even if the likelihood of an outflow with respect to any one 
item included in the same class of obligations may be small
share based payments
the company operates an equitysettled sharebased compensation plan the fair value of the employee services received in 
exchange for the grant of the options is recognised as an expense the total amount to be expensed over the vesting period is 
determined by reference to the fair value of the options granted excluding the impact of any nonmarket vesting conditions for 
example profitability and sales growth targets  
the proceeds received net of any directly attributable transaction costs are credited to share capital nominal value and share 
premium when the options are exercised
property plant and equipment
property plant and equipment are shown in the balance sheet at their historical cost less accumulated depreciation and 
impairment historical cost includes expenditure that is directly attributable to the acquisition and installation of the items 
subsequent costs are included in the assets’ carrying amounts or recognised as a separate asset as appropriate only when it is 
probable that future economic benefits associated with them will flow to the group and the cost of the item can be measured 
reliably all other repairs and maintenance are charged to the income statement as incurred
depreciation is provided so as to write off the initial cost of each asset to its residual value on a straight line basis over its estimated 
useful life as follows
long leasehold buildings  15 years
fixtures and fittings  5 years
plant and machinery  4–10 years
computer equipment  3 years
motor vehicles   5 years
the assets’ residual values and useful lives are reviewed and adjusted if appropriate by the directors at each balance sheet 
date where the carrying amount of an asset is greater than its estimated recoverable amount it is written down immediately to 
its recoverable amount gains and losses on disposals are determined by comparing proceeds with carrying amounts these are 
included in the income statement
government grants
government grants are recorded initially as deferred income and recognised in the income statement in line with the expense to 
which they contribute for grants in respect of the purchase of property plant and equipment the deferred income is released over 
the life of the related assets for grants in respect of staff costs the deferred income is released over the monitoring period of the 
grant offer 
intangible assets – goodwill
goodwill represents the excess of the cost of an acquisition over the fair value of the net identifiable assets and liabilities acquired 
both tangible and intangible
goodwill is tested at least annually for impairment and carried at cost less accumulated impairment losses any impairment is 
recognised immediately in the income statement and cannot be subsequently reversed goodwill is allocated to groups of cash
generating units for the purpose of impairment testing gains or losses on the disposal of an entity include the carrying amount of 
goodwill relating to the entity sold 
internally generated intangible assets – research and development
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 development is recognised only if all of the following conditions are 
met an asset is created that can be separately identified it is probable that the asset created will generate future economic benefits 
and the development cost of the asset can be measured reliably
internally generated intangible assets are amortised on a straight line basis over their useful lives where no internallygenerated 
intangible asset can be recognised development expenditure is recognised as an expense in the period in which it is incurred 30       pure wafer plc   annual report and accounts 2011
2 summary of significant accounting policies continued
intangible assets – other
these consist mainly of process development costs capitalised the assets are amortised on a straightline basis over the expected 
useful economic life of five years the assets’ residual values and useful lives are reviewed and adjusted if appropriate by the 
directors at each balance sheet date
impairment of assets
assets that have an indefinite life are not subject to amortisation and are tested at least annually for impairment assets that are 
subject to amortisation are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount 
may not be recoverable an impairment loss is recognised in the income statement for the amount by which the carrying amount of 
the asset exceeds its recoverable amount the recoverable amount is the higher of the fair value less costs to sell and the value in 
use for the purpose of assessing impairment assets are grouped at the lowest levels for which there are separately identifiable cash 
flows cashgenerating units
inventories
inventories are stated at the lower of cost and net realisable value cost is determined using the firstin firstout fifo method 
the cost of finished goods and work in progress comprises raw materials direct labour  other direct costs and related production 
overheads based on normal operating capacity but excludes borrowing costs work in progress is valued to reflect the historical 
yield from the reclaim process net realisable value is the estimated selling price in the ordinary course of business less the 
estimated costs of completion and selling expenses
leasing
assets held under finance leases are recognised as assets of the group at their fair value or if lower at the present value of the 
minimum lease payments each determined at the inception of the lease the corresponding liability to the lessor is included in the 
balance sheet as a finance lease obligation lease payments are apportioned between finance charges and reduction of the lease 
obligation so as to achieve a constant rate of interest on the remaining liability finance charges are charged directly against income
rentals payable under operating leases are charged to income on a straight line basis over the term of the relevant lease
benefits received and receivable as an incentive to enter into an operating lease are also spread on a straight line basis over the lease 
term
restructuring costs
certain costs are classified as relating to restructuring where they relate to the incremental cost of undertaking a significant change 
to the operations or staff structure of the business 
operating loss
operating loss is stated after charging restructuring costs but before investment income finance costs and foreign exchange gains 
and losses
borrowing costs
borrowing costs directly attributable to the acquisition construction or production of qualifying assets which are assets that 
necessarily take a substantial period of time to get ready for their intended use or sale are added to the costs of those assets until 
such time as the assets are substantially ready for their intended use or sale
investment income earned on the temporary investment of specific borrowings pending their expenditure on qualifying assets is 
deducted from the borrowing costs eligible for capitalisation
all other borrowing costs are recognised in the income statement in the period in which they are incurred
cash and cash equivalents
in the consolidated statement of cash flows cash and cash equivalents includes cash in hand deposits held at all banks and bank 
overdrafts in the consolidated balance sheet bank overdrafts are shown within borrowings in current liabilities
taxes
tax on the profit or loss for the year comprises current and deferred tax
current tax is the expected tax payable on the taxable income for the year  using tax rates substantively enacted at the balance sheet 
date and any adjustments to tax payable in respect of previous years
deferred tax is provided in full on temporary differences between the carrying amount of assets and liabilities in the financial 
statements and the tax base deferred tax assets are recognised only to the extent that it is probable that future taxable profits will 
be available against which the temporary differences can be utilised deferred tax assets and liabilities are not discounted
deferred tax is determined using the tax rates that have been enacted or substantively enacted by the balance sheet date and are 
expected to apply when the deferred tax liability is settled or the deferred tax asset is realised

taxes continued
deferred tax is provided on temporary differences arising on investments in subsidiaries and associates except where the timing of 
the reversal of the temporary difference is controlled by the group and it is probable that the temporary difference will not reverse in 
the foreseeable future
tax is recognised in the income statement except where it relates to items recognised directly in equity in which case it is 
recognised in equity
share capital
ordinary shares are classified as equity incremental costs directly attributable to the issue of new shares or options are shown in 
equity as a deduction net of tax from the proceeds 
pensions
the company operates a defined contribution scheme that is available to all staff upon the completion of any probationary period
3 critical accounting judgements and key sources of estimation uncertainty
critical accounting judgements and key sources of estimation uncertainty
in the application of the group’s accounting policies which are described in note 2 the directors are required to make judgements 
estimates and assumptions about the carrying amounts of assets and liabilities that are not readily apparent from other sources 
the estimates and associated assumptions are based on historical experience and other factors that are considered to be relevant 
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 if the revision affects only that period or in the period of the revision and future periods 
if the revision affects both current and future periods
key sources of estimation uncertainty
the key assumptions concerning the future and other key sources of estimation uncertainty at the balance sheet date that have a 
significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year are 
discussed below
impairment of noncurrent assets
determining whether goodwill property plant and equipment or intangible assets are impaired requires an estimation of the value 
in use of the cash generating units cgus to which those assets are allocated the group has two separate cgus representing 
the uk and the us businesses the value in use calculation requires the entity to estimate the future cash flows expected to arise 
from the cash generating unit and a suitable discount rate in order to calculate present value the carrying amount of goodwill was 
663m and property plant and equipment was 3097m at the balance sheet date 
the group prepares cash flow forecasts derived from the most recent financial budgets approved by management for the first three 
years assuming growth based on detailed sales and cost forecasts the cash flows are extrapolated in perpetuity assuming a 225 
growth rate representing the directors’ estimate of the average longterm growth rate for the markets in which the group operates 
the rate used to discount the forecast cash flows of each of the cgus as defined above was based on the group’s pre tax weighted 
average cost of capital of 89  
for both cgus the impairment review is sensitive to the forecast level of sales sales are planned to increase as demand continues 
to return to the market through the three year forecast period the impairment review includes significant headroom to address this 
there is a risk of impairment if sales were to fall more than 40 below expectation
the review of the uk cgu is also sensitive to discount rate and the forward usd rate were the discount rate to increase to above 
171 or the longterm usd forward rate to rise above 183 there would be a risk of impairment
based on the assumptions made by the directors no impairment has been booked
fair value of derivatives and other financial instruments
as described in note 22 the directors use their judgement in selecting appropriate valuation techniques for financial instruments 
not quoted on an active market valuation techniques commonly used by market practitioners are applied for derivative financial 
instruments assumptions are made based on quoted market rates adjusted for specific features of the instrument other financial 
instruments are valued using a discounted cash flow analysis based on the assumptions supported where possible by observable 
market prices or rates the fair value of financial instruments at the balance sheet date was a net liability of 5000 2010 
55000   32       pure wafer plc   annual report and accounts 2011
deferred tax
the group has tax losses of some 93m available for offset against future uk taxable profits in determining the value of the 
deferred tax asset that can be attributed to these losses the directors have to estimate likely future taxable profits and the period 
over which the asset may be recovered the directors consider the most uptodate forecasts for the uk business and assess the 
risks inherent in achieving those forecasts at the balance sheet date no deferred tax asset has been recorded the deferred tax 
asset may be recognised again in future if there is an improvement in the forecast taxable profits 
3 critical accounting judgements and key sources of estimation uncertainty continued
key sources of estimation uncertainty continued
useful life of property plant and equipment
the group’s plant and machinery is amortised over a period of seven to ten years in estimating the life of the equipment the 
directors have to consider the likely period over which the technology will be used in the market and the ability of the business to 
maintain the equipment to an appropriate condition for use were the technology to be superseded in a much shorter timeframe 
than this the carrying value would need to be depreciated over a shorter timeframe resulting in an increase in the annual 
depreciation charge

business and geographical segments are reported in a manner consistent with internal reporting provided to the chief operating 
decisionmaker  which has been identified as the pure wafer plc board
the group’s activities and turnover primarily consist of the reclamation and reprocessing of silicon test wafers in the uk and the 
us for external customers the solar business is not deemed to be a separate segment for the purposes of the 2011 results as it 
did not commence commercial trading until after the yearend

goodwill which relates to the february 2007 acquisition of the group’s us business is denominated in us dollars usd and is 
considered to represent a single cash generating unit cgu
goodwill is reviewed annually or when other events or changes in circumstance indicate that the carrying amount may not be fully 
recoverable
the recoverable amount of this cgu is determined from value in use calculations the key assumptions for the value in use 
calculation are those regarding the discount rate growth rate and expected changes to selling prices and direct costs management 
estimates discount rates using pretax rates that reflect current market assessments of the time value of money and the risks 
specific to the cgu the growth rates are based on industry growth forecasts changes in selling prices and direct costs are based 
on past practices and expectations of future changes in the market
the group prepares cash flow forecasts derived from the most recent financial budgets approved by the board for the first three 
years assuming growth based on detailed sales and cost forecasts the cash flows are then extrapolated in perpetuity assuming a 
225 growth rate which the directors’ believe represents the long term average growth rate for this cgu and the market in which 
it operates the rate used to discount the forecast cash flows is based on a pre tax weighted average cost of capital of 89 which 
reflects the overall business risks associated with this cgu
the impairment review is sensitive to the forecast level of sales sales are planned to increase as demand returns to the market 
through the three year forecast period 
other intangibles
other intangibles represent costs associated with process development with the exception of solar development costs capitalised 
costs are amortised over their useful economic life which is estimated at five years 
solar development costs totalling 741k were capitalised in the period solar development costs have not yet been amortised 
as the solar division has not yet commenced commercial trading 38       pure wafer plc   annual report and accounts 2011

financial risk management objectives
the group’s financial instruments comprise bank loans finance leases derivative financial instruments and trade receivables and 
trade payables that arise already from its operations the purpose of the instruments is to raise finance for group activities 
the group seeks to minimise the effects of financial risks by using derivative financial instruments to hedge known exposures the 
interest rates on bank loans are managed through the use of interest rate swaps and interest on the remaining financial liabilities 
are fixed the use of financial derivatives is governed by the group’s policies approved by the board of directors which provide 
written principles on foreign exchange risk interest rate risk credit risk the use of financial derivatives and nonderivative financial 
instruments and the investment of excess liquidity the group does not enter into or trade financial instruments including derivative 
financial instruments for speculative purposes
market risk
the group’s activities expose it primarily to the financial risks of changes in foreign currency exchange rates and interest rates 
the group enters into a variety of derivative financial instruments to manage its exposure to interest rate and foreign currency risk 
including
•       interest rate swaps to mitigate the risk of rising interest rates
foreign currency risk management 
the group undertakes certain transactions denominated in foreign currencies hence exposures to exchange rate fluctuations arise 
exchange rate exposures are managed within approved policy parameters utilising forward foreign exchange contracts 
the carrying amounts of the group’s foreign currency denominated monetary assets and monetary liabilities at the reporting date 
are as follows
2011
000
2010

euro 227 48
sterling 120 
monetary liabilities

sterling 4275 1844
yen 75 110
interest rate risk management
the group is exposed to interest rate risk as entities in the group borrow funds at both fixed and floating interest rates the risk is 
managed by the group maintaining an appropriate mix between fixed and floating rate borrowings by the use of interest rate swap 
contracts to fix the interest rate on the floating rate loans 
the group’s exposures to interest rates on financial assets and financial liabilities are detailed in the liquidity risk management 
section of this note 
interest rate swap contracts
under interest rate swap contracts the group agrees to exchange the difference between fixed and floating rate interest amounts 
calculated on agreed notional principal amounts such contracts enable the group to mitigate the risk of higher interest rates on the 
fair value of issued fixed rate debt held and the cash flow exposures on the issued variable rate debt held the fair value of interest 
rate swaps at the reporting date is determined by discounting the future cash flows using the curves at the reporting date and the 
credit risk inherent in the contract and is disclosed below the average interest rate is based on the outstanding balances at the 
end of the financial year the current contracts were matched to the original payment profiles for the group debt with the financial 
restructuring package that has taken place after the year end these are no longer matched the directors will consider the impact of 
the mismatch in evaluating the interest rate strategy going forward
the group has entered into interest rate swap agreements in respect of the bank loans 
the company has one interest rate swap contract this expires on 12 february 2012 the fair value of the contract as at 30 june 
2011 was a liability of 5000 2010 20158 the contract is net settled 
credit risk management
credit risk refers to the risk that a counterparty will default on its contractual obligations resulting in financial loss to the group the 
group has adopted a policy of only dealing with creditworthy counterparties the group only transacts with major high street banks 
trade receivables consist of a large number of customers spread across diverse geographical areas ongoing credit evaluation is 
performed on the financial condition of accounts receivable the group does not have any significant credit risk exposure to a single 
counterparty the details are disclosed in note 16  44       pure wafer plc   annual report and accounts 2011

continuously monitoring forecast and actual cash flows and matching the maturity profiles of financial assets and liabilities

• foreign currency forward contracts are measured using quoted forward exchange rates and yield curves derived from quoted 
 interest rates matching maturities of the contracts

 applicable yield curves derived from quoted interest rates and
• the carrying amount of financial assets and financial liabilities recorded at amortised cost approximates to their fair value

accounting policies adopted which have been applied consistently throughout the current and the prior financial year  are described 
below
going concern
the group’s business activities together with the factors likely to affect its future development performance and position are 
set out in the chairman’s statement on pages 4 and 5 the financial position of the group its cash flows liquidity position and 
borrowing facilities are described in the finance review on page 8 in addition note 22 to the financial statements includes the 
group’s objectives policies and processes for managing its capital its financial risk management objectives details of its financial 
instruments and hedging activities and its exposures to credit risk and liquidity risk 
as described in the chairman’s statement on pages 4 and 5  the current economic environment remains challenging the group has 
recorded a pretax loss however  given the facilities that are currently in place the group has significant headroom above its forecast 
cash requirement which will allow it to manage its business risks successfully despite the current uncertain outlook 
the directors have assessed the balance sheet and likely future cash flows of the company at the date of signing the audit report 
this review considered detailed forecasts for the period to 30 june 2013 on this basis the directors have concluded that it is 
appropriate to prepare the financial statements on a going concern basis 
the key sensitivity in the forecasts includes the achievement of increased sales volumes the business has experienced an upturn in 
demand for its services and the directors believe that this will be sustained sales prices are assumed to remain largely unchanged 
after making enquiries the directors have a reasonable expectation that the group and the company have adequate resources 
to continue in operational existence for the foreseeable future for this reason they continue to adopt the going concern basis in 
preparing the annual report and financial statements 
accounting convention
the financial statements are prepared under the historical cost convention modified for the fair value of share based payments 
investments
investments in subsidiaries and associates are held as fixed assets and are stated at cost less provision for any impairment
cash flow statement
under financial reporting standard no 1 revised 1996 the company is not required to prepare a cash flow statement as a group 
cash flow statement has been included in the financial statements of the group 
share based payments
the company operates an equitysettled sharebased compensation plan  the fair value of the employee services received in 
exchange for the grant of the options is recognised as an expense  the total amount to be expensed over the vesting period is 
determined by reference to the fair value of the options granted excluding the impact of any nonmarket vesting conditions for 
example profitability and sales growth targets  
the proceeds received net of any directly attributable transaction costs are credited to share capital nominal value and share 
premium when the options are exercised
taxation
current tax is provided at amounts expected to be paid or recovered using the tax rates and laws that have been enacted or 
substantively enacted at the balance sheet date 
deferred taxation is provided in full on timing differences that result in an obligation at the balance sheet date to pay more tax or 
a right to pay less tax at a future date at rates expected to apply when they crystallise based on current tax rates and law timing 
differences arise from the inclusion of items of income and expenditure in taxation computations in periods different from those in 
which they are included in the financial statements
deferred tax assets are recognised to the extent that it is regarded as more likely than not that they will be recovered deferred tax 
assets and liabilities are not discounted

our history
pure wafer was established in 2000 by 
a management team widely experienced 
in the semiconductor industry with the 
backing of strategic investment from 
venture capital and industry partners
the group floated on aim in december 
2004 and february 2007 pure wafer 
completed the acquisition of a wafer 
reclaim facility in arizona us
our facilities

the art purpose built facility situated in 
a technology park in swansea wales and 
is the most advanced plant of its kind in 
europe the size of the facility is in excess 
of 4500m
2
 and includes over 2000m
2
 of 
production cleanrooms
the facility in prescott arizona was 
constructed in 1997 and has received 
in excess of 50m of investment since 
then the highvolume hightech fab 
was originally designed for 200mm and 
smaller diameter wafer reclaim services 
but following the acquisition by pure 
wafer in 2007 capability to reclaim 
300mm wafers has been installed
we have installed the latest generation 
of tools available on the market with 
the most advanced equipment as used 
by integrated chip ic and prime silicon 
producers with the highest technical 
specifications we are positioned to offer 
the most effective wafer reclaim services 
to our customers with minimal silicon 
removal this enables our customers to 
maximise the number of times a test 
wafer can be reclaimed
pure wafer is a worldwide leader in the provision of 300mm 
wafer reclaim services these services enable semiconductor 
manufacturers to gain efficiencies through the increased use 
of silicon test wafers within their production processes annual report and accounts 2011  pure wafer plc       3
our process
at pure wafer our process for reclaiming 
test wafers involves the following key 
stages
inspection of the wafers for defects •	
and classification by type of 
contaminant to be removed
submersion in a precise mix of •	
chemicals appropriate to remove the 
contaminant 
assessment of flatness and •	
correction of defects using pure 
wafer’s advanced polishing processes
cleaning and drying •	
final quality inspection and •	
packaging for return to the customer
wafer reclaim
during the many stages of the manufacturing process of 
semiconductors large quantities of test wafers are used to check 
the accurate calibration of equipment these test wafers are a key 
consumable in the manufacture of semiconductors and the ability 
to reclaim them through pure wafer’s advanced process provides 
manufacturers with the opportunity to reduce costs
the semiconductor industry transition to 300mm wafers in now 
well advanced in order for manufacturers to continue to increase 
functionality at a reduced cost the industry has sought to increase 
the size of wafers on which semiconductors are manufactured 
300mm wafer processing now represents the fastest growing area 
of the semiconductor industry
