Annual Report 2012
Recognition therefore involves judgement regarding the future nancial
performance of the particular legal entity or tax group in which the
deferred tax asset has been recognised.
Historical differences between forecast and actual taxable prots have
not resulted in material adjustments to the recognition of deferred
taxassets.
Business combinations
The recognition of business combinations requires the excess of the
purchase price of acquisitions over the net book value of assets acquired
to be allocated to the assets and liabilities of the acquired entity.
TheGroup makes judgements and estimates in relation to the fair value
allocation of the purchase price. If any unallocated portion is positive
itisrecognised as goodwill and if negative, it is recognised in the
incomestatement.
Goodwill
The amount of goodwill initially recognised as a result of a business
combination is dependent on the allocation of the purchase price to the
fair value of the identiable assets acquired and the liabilities assumed.
The determination of the fair value of the assets and liabilities is based,
toa considerable extent, on management’s judgement.
Allocation of the purchase price affects the results of the Group as nite
lived intangible assets are amortised, whereas indenite lived intangible
assets, including goodwill, are not amortised and could result in differing
amortisation charges based on the allocation to indenite lived and
nite lived intangible assets.
On transition to IFRS the Group elected not to apply IFRS 3, “Business
combinations”, retrospectively as the difculty in applying these
requirements to the large number of business combinations completed
by the Group from incorporation through to 1 April 2004 exceeded
anypotential benets. Goodwill arising before the date of transition to
IFRS,after adjusting for items including the impact of proportionate
consolidation of joint ventures, amounted to £78,753 million.
If the Group had elected to apply the accounting for business
combinations retrospectively it may have led to an increase or decrease
in goodwill and increase in licences, customer bases, brands and related
deferred tax liabilities recognised on acquisition.
Finite lived intangible assets
Other intangible assets include the Group’s aggregate amounts spent
on the acquisition of licences and spectrum, computer software,
customer bases, brands and development costs. These assets
arisefromboth separate purchases and from acquisition as part of
businesscombinations.
On the acquisition of mobile network operators the identiable
intangible assets may include licences, customer bases and brands.
Thefair value of these assets is determined by discounting estimated
future net cash ows generated by the asset where no active market for
the assets exists. The use of different assumptions for the expectations
of future cash ows and the discount rate would change the valuation
ofthe intangible assets.
The relative size of the Group’s intangible assets, excluding goodwill,
makes the judgements surrounding the estimated useful lives critical
tothe Group’s nancial position and performance.
At 31 March 2012 intangible assets, excluding goodwill, amounted to
£21,164 million (2011: £23,322 million) and represented 15.2% (2011:
15.4%) of the Group’s total assets.
Estimation of useful life
The useful life used to amortise intangible assets relates to the
expectedfuture performance of the assets acquired and management’s
judgement of the period over which economic benet will be derived
from the asset. The basis for determining the useful life for the most
signicant categories of intangible assets is as follows:
Licences and spectrum fees
The estimated useful life is generally the term of the licence unless there
is a presumption of renewal at negligible cost. Using the licence term
reects the period over which the Group will receive economic benet.
For technology specic licences with a presumption of renewal at
negligible cost, the estimated useful economic life reects the Group’s
expectation of the period over which the Group will continue to receive
economic benet from the licence. The economic lives are periodically
reviewed taking into consideration such factors as changes in
technology. Historically any changes to economic lives have not been
material following these reviews.
Customer bases
The estimated useful life principally reects management’s view of
theaverage economic life of the customer base and is assessed by
reference to customer churn rates. An increase in churn rates may
leadto a reduction in the estimated useful life and an increase in the
amortisation charge. Historically changes to the estimated useful
liveshave not had a signicant impact on the Group’s results and
nancialposition.
Capitalised software
The useful life is determined by management at the time the
softwareisacquired and brought into use and is regularly reviewed
forappropriateness. For computer software licences, the useful life
represents management’s view of expected term over which the Group
will receive benets from the software, but not exceeding the licence
term. For unique software products controlled by the Group, the
lifeisbased on historical experience with similar products as well
asanticipation of future events which may impact their life such as
changes in technology. Historically changes in useful lives have not
resulted in material changes to the Group’s amortisation charge.
Property, plant and equipment
Property, plant and equipment also represent a signicant proportion
ofthe asset base of the Group being 13.4% (2011: 13.3%) of the
Group’stotal assets. Therefore the estimates and assumptions made
todetermine their carrying value and related depreciation are critical
tothe Group’s nancial position and performance.
Estimation of useful life
The charge in respect of periodic depreciation is derived after
determining an estimate of an asset’s expected useful life and the
expected residual value at the end of its life. Increasing an asset’s
expected life or its residual value would result in a reduced depreciation
charge in the consolidated income statement.
The useful lives and residual values of Group assets are determined by
management at the time the asset is acquired and reviewed annually
forappropriateness. The lives are based on historical experience
withsimilar assets as well as anticipation of future events which may
impacttheir life such as changes in technology. Furthermore, network
infrastructure is only depreciated over a period that extends beyond
theexpiry of the associated licence under which the operator provides
telecommunications services if there is a reasonable expectation of
renewal or an alternative future use for the asset.
Historically changes in useful lives and residual values have not resulted
in material changes to the Group’s depreciation charge.
Provisions and contingent liabilities
The Group exercises judgement in measuring and recognising
provisions and the exposures to contingent liabilities related to pending
litigation or other outstanding claims subject to negotiated settlement,
mediation, arbitration or government regulation, as well as other
contingent liabilities (see note 29 to the consolidated nancial
statements). Judgement is necessary in assessing the likelihood that a
pending claim will succeed, or a liability will arise, and to quantify the
possible range of the nancial settlement. Because of the inherent
uncertainty in this evaluation process, actual losses may be different
from the originally estimated provision.
