Forward looking statements
Certain statements in this document are forward looking with respect to plans, goals and expectations relating to the future financial
position, business performance and results of Nationwide. Although Nationwide believes that the expectations reflected in these
forward-looking statements are reasonable, Nationwide can give no assurance that these expectations will prove to be an accurate
reflection of actual results. By their nature, all forward looking statements involve risk and uncertainty because they relate to future
events and circumstances that are beyond the control of Nationwide including, amongst other things, UK domestic and global
economic and business conditions, market related risks such as fluctuation in interest rates and exchange rates, inflation/deflation,
the impact of competition, changes in customer preferences, risks concerning borrower credit quality, delays in implementing
proposals, the timing, impact and other uncertainties of future acquisitions or other combinations within relevant industries, the
policies and actions of regulatory authorities, the impact of tax or other legislation and other regulations in the jurisdictions in which
Nationwide operates. As a result, Nationwide’s actual future financial condition, business performance and results may differ
materially from the plans, goals and expectations expressed or implied in these forward-looking statements. Due to such risks and
uncertainties Nationwide cautions readers not to place undue reliance on such forward-looking statements.
Nationwide undertakes no obligation to update any forward-looking statements whether as a result of new information, future
events or otherwise.
This document does not constitute or form part of an offer of securities for sale in the United States. Securities may not be offered
or sold in the United States absent registration or an exemption from registration. Any public offering to be made in the United
States will be made by means of prospectus that may be obtained from Nationwide and will contain detailed information about
Nationwide and management as well as financial statements.
Basis of preparation
This document has been prepared on the basis of International Financial Reporting Standards, incorporating IFRS 9 and its
consequential amendments to other standards including IFRS 7, as endorsed by the EU and including transitional arrangements for
regulatory capital as appropriate. All other accounting policies are unchanged from those published in the Annual Report and
Accounts 2018. Comparative information for the accounting periods prior to adoption will not be restated, as permitted by IFRS 9.
This document is unaudited.
Terminology used in this report is consistent with that used in the Annual Report and Accounts 2018. Copies of the Annual Report
and Accounts 2018 are available on the Group’s website at nationwide.co.uk. A full glossary can also be found on the Group’s website.

Summary
Impact of IFRS 9
The day one impact of IFRS 9 is limited, leading to a reduction in members’ interests and equity of approximately 1.3%, primarily
due to increased impairment provisions. The impact on the main capital ratios is not significant.
These impacts are based on assumptions and judgements at 5 April 2018 which are subject to change. IFRS 9 provisions may be
more volatile compared to IAS 39 due to the forward-looking nature of expected credit loss (ECL) provisions.
Movement from IAS 39 to IFRS 9 impairment provisions
The chart above shows the components of the overall increase of impairment provision from IAS 39 to IFRS 9. The key differences
between IAS 39 and IFRS 9 impairment provisions are summarised as follows:
1) Previously under IAS 39, provision was held in relation to up to date loans where a loss event had occurred but had not
yet been identified through evidence of arrears (£110 million).
2) By contrast under IFRS 9, a provision is calculated for all loans. The value of a 12 month ECL for all up to date loans is
£83m.
3) The IFRS 9 approach increases ECL provisions from a 12 month ECL to a lifetime ECL when there is evidence of a significant
increase in credit risk since origination, or when the loan is impaired. This is one of the main drivers of the increase in
provisions from IAS 39 to IFRS 9, particularly for loans which are not yet impaired. The impact of this is £89 million, of
which the increase for loans impaired under IAS 39 is £15m.
4) The impact of including an allowance for multiple economic scenarios (MES) is the other significant driver of the increase
in impairment provisions under IFRS 9. The effect of this factor is £110 million.

Analysis of loans and advances including stage distribution
The calculation of ECL uses a three stage approach (stage 1 for performing assets, stage 2 for assets with a significant increase in
credit risk since origination and stage 3 for assets which are credit impaired). Staging is explained in more detail in the expected
credit loss approach section of this report.
The following table summarises the impact of the initial adoption of IFRS 9 expected credit losses on loans and advances to
customers which are carried at amortised cost on the balance sheet. The tables show the stage allocation of loans at 5 April 2018,
the IFRS 9 impairment provisions and the resulting provision coverage ratios. The provision coverage ratio is calculated by dividing
the ECL provision by the gross loans for each main lending portfolio. These indicators will be included in our interim results for the
period ending 30 September 2018 and in the Annual Report and Accounts 2019. For investment securities that are subject to ECLs,
the expected credit losses are below £1m and therefore immaterial for the purposes of this report.

Of the £20,012 million stage 2 loans that have experienced a significant increase in credit risk, £481 million are loans where this is
due to arrears of 30 days past due or more, whilst £19,531 million is due to non-arrears factors.
Consumer banking stage 3 gross loans and ECL include charged off balances. These are in relation to accounts which are closed to
future transactions and are held on the balance sheet for an extended period (up to 36 months) whilst recovery procedures take
place. The total consumer banking provision coverage ratio excluding both the charged off balance and the related ECL (£185 million
and £175 million respectively) is 4.84%.
The stage 3 POCI loans were recognised on the Group’s balance sheet when the Derbyshire Building Society was acquired in
December 2008. These mainly interest only residential loans were 90 days or more in arrears when they were acquired by the
Group and so have been classified as credit impaired on acquisition. A lifetime ECL provision of £7 million has been deducted from
the gross carrying amount as a transitional adjustment. Any subsequent changes (favourable or unfavourable) in lifetime ECL will
be recognised in the income statement from 5 April 2018.

Summary continued
Potential volatility of ECL provisions
Despite the fact that actual cash flows and losses realised on loans are unaffected by the adoption of IFRS 9, ECL provisions are
expected to be higher, and potentially more volatile, than IAS 39 incurred loss provisions. This is due to the change to an expected
credit loss basis for calculating provisions. In the future, if expectations of economic conditions or observed loss rates deteriorate,
the level of ECL provisions will be expected to increase as models and assumptions are revised. Conversely when economic forecasts
become more optimistic, provisions are expected to reduce. In addition, volatility could occur when significant numbers of loans
move between stages, particularly from stage 1 to stage 2, changing the basis of provisioning from 12 month to lifetime ECL. Overall
the degree of volatility from these factors is uncertain and is likely to fluctuate with changing circumstances, particularly
macroeconomic conditions and outlook.

Introduction
With effect from 5 April 2018 Nationwide Building Society and its subsidiaries (the Group) has adopted IFRS 9: Financial Instruments
to replace IAS 39 Financial Instruments: Recognition and Measurement. IFRS 9 includes requirements for the classification and
measurement of financial instruments, impairment of financial assets and hedge accounting.
The Group’s first results prepared under IFRS 9 will be published in the Interim Management Statement for the quarter ending 30
June 2018. The Group’s first full year set of financial statements prepared under IFRS 9 will be published in the Annual Report and
Accounts for the year ending 4 April 2019.
This document summarises the financial impact of IFRS 9 at adoption on 5 April 2018. Additional information is included to allow
readers to understand the approach taken to calculating expected credit losses under IFRS 9, including the key concepts and
judgements made.
The principal requirements of IFRS 9 are as follows:
Classification and measurement
The classification of financial assets is based on the objectives of the Group’s business model and the contractual cash flow
characteristics of the financial instruments. Financial assets are classified as held at amortised cost, at fair value through other
comprehensive income (FVOCI), or at fair value through profit or loss (FVTPL). The impact of changes from the accounting treatment
under IAS 39 for Nationwide is limited. Assets with contractual cash flow characteristics that have resulted in a reclassification from
amortised cost to FVTPL include some closed book equity release and shared ownership retail loans, and a small number of
commercial loans. The only changes to the classification and measurement of financial liabilities are where liabilities are elected to
be measured at fair value on the balance sheet on adoption; the Group has not made any such election.
The review of the contractual terms of financial assets has resulted in asset values reducing by £36 million as a result of certain
loans being reclassified from amortised cost to FVTPL. Most of this reduction in value relates to the removal of fair value hedge
accounting adjustments for equity release loans.
Impairment of financial assets
IFRS 9 changes the basis of recognition of impairment on financial assets from an incurred loss to an expected credit loss (ECL)
basis for amortised cost and FVOCI financial assets.
IFRS 9 introduces a number of new concepts and changes to the approach to provisioning compared with the previous methodology
under IAS 39:
• Expected credit losses are based on an assessment of the probability of default, exposure at default and loss given default,
discounted to give a net present value. The estimation of ECL is unbiased and probability weighted, taking into account all
reasonable and supportable information, including forward looking economic assumptions and a range of possible
outcomes. IFRS 9 has the effect of bringing forward recognition of impairment losses relative to IAS 39 which requires
provisions to be recognised only when there is objective evidence of credit impairment.
• On initial recognition, and for financial assets where there has not been a significant increase in credit risk since the date
of advance, IFRS 9 provisions are recognised for expected credit default events within the next 12 months.
• A key feature of IFRS 9 compared with the previous approaches under IAS 39 is that where a loan has experienced a
significant increase in credit risk since initial recognition, even though this may not lead to the conclusion that the loan is
credit impaired, provisions are made based on expected credit losses over the full life of the loan.
• For assets where there is evidence of credit impairment, provisions are made for lifetime expected credit losses under
IFRS 9. Interest will be recognised net of impairment provisions.
• All IFRS 9 ECL provisions take account of forward looking economic assumptions and a range of possible outcomes. Under
IAS 39, provisions were based on the asset’s carrying value and the present value of the estimated future cash flows. IAS
39 did not explicitly take account of a range of possible economic outcomes including forecasts of any downturn in the
economic cycle.
Further details of our approach are contained in the expected credit loss approach section of this report.

Introduction continued
Hedge accounting
The hedge accounting requirements of IFRS 9 are designed to create a stronger link with financial risk management. The
International Accounting Standards Board (IASB) is currently exploring an accounting model for dynamic risk management
accounting (macro hedge accounting). The Group currently takes the option permitted by IFRS 9 to continue to apply the hedge
accounting requirements of IAS 39. The Group will however implement the revised hedge accounting disclosure requirements
included in the related amendments to IFRS 7 Financial Instruments: Disclosure.
Implementation strategy
The Group established an IFRS 9 implementation programme in 2014 with formal governance reporting to the Chief Financial Officer
and Chief Risk Officer. Progress was reported regularly to the Audit Committee during the life of the programme. This included
formal oversight of the new IFRS 9 ECL calculations and economic assumptions ahead of the adoption of IFRS 9.
The Group’s implementation strategy for IFRS 9 has been based on an integrated solution using common systems, tools and data
to assess credit risk and account for ECL. This is consistent with guidance issued by the Basel Committee on Banking Supervision
(BCBS), and has entailed changes to the governance, controls, models and business processes relating to credit loss provisioning.
The IFRS 9 implementation programme was completed in advance of adoption on 5 April 2018, allowing a period of refinement of
the new IFRS 9 systems, models and processes during the 2017/18 financial year.
Governance
IFRS 9 impairment provisions are subject to review and oversight through Nationwide’s existing risk governance frameworks. This
includes controls over the data, models and financial controls used in the IFRS 9 processes.
In addition, monthly forums comprising members of the Risk and Finance communities review model outputs, challenging the
assumptions used and approving changes to the operation of ECL models. They consider whether modelled outputs adequately
reflect credit risk, and regularly review any adjustments required to modelled provisions. A new forum has been created to review
and approve the forward-looking economic scenarios used as part of the ECL calculation. Provisions are ultimately approved by the
CFO and regularly reviewed by the Group’s Audit Committee.

Balance sheet and reserves adjustments continued
Notes:
1. Includes a debt security that has been transferred from available for sale investment securities to FVTPL due to its contractual
cash flow characteristics.
2. This reduction in fair value for portfolio hedged risk relates to removal of fair value hedge accounting adjustments for loans that
have been reclassified from amortised cost to FVTPL, and which therefore no longer qualify for hedge accounting.
3. The reduction of amortised cost loans and advances to customers under IAS 39 relates to loans reclassified under IFRS 9 as FVTPL
due to their contractual cash flow characteristics.
4. £2 million is the net impact of the transitional lifetime ECL adjustment on the balance sheet carrying value of POCI loans, and the
adjustment to credit impaired loans to restore the carrying value to the contractual amount owed.
5. The reduction of the amortised cost loans and advances to customers due to impairment (£171m) is the difference between
IFRS 9 ECL impairment and the IAS 39 incurred loss provisions.
6. Carrying values of FVTPL loans and advances to customers increased by £1m on transition to IFRS 9.
7. The valuation of the deferred tax assets recognised on adoption of IFRS 9 reflects HMRC’s legislation that the tax effect of the
impact on adoption of IFRS 9 should be realised over the ten years following adoption. Deferred tax is determined using tax rates
and laws that are expected to apply in the period when the deferred tax asset is realised based on rates enacted or substantively
enacted at the balance sheet date, including the banking surcharge when applicable.
8. An additional £1 million has been provided separately within provisions for liabilities and charges. This relates to provisions
against separately identifiable irrevocable commitments for the pipeline of personal loans, commercial loans and mortgages.
Overdrafts and credit card commitments are provided for within the ECL provision models, with allowance for future drawdowns
made as part of the exposure at default (EAD) element of the ECL calculation for each account.
9. The transfer from fair value through other comprehensive income reserve to general reserve relates to the accumulated available
for sale reserve in respect of financial instruments that have been reclassified from AFS to FVTPL.

Expected credit loss approach
Measuring credit losses
Expected Credit Loss (ECL) is calculated using the following formula:
Probability of default (‘PD’) x Exposure at default (‘EAD’) x Loss given default (‘LGD’)
These terms are defined as follows:
Term Definition
Probability of
default (‘PD’)
The probability of a default event occurring, based on conditions existing at the reporting date and future
economic conditions that affect credit risk. Probability of default has been determined based upon unlikeliness
to pay indicators, plus backstop criteria based upon a measure of days past due. The lifetime PD forms part of
the IFRS 9 stage assessment as well as the ECL calculation.
Exposure at
default (‘EAD’)
The expected outstanding balance of the asset at default, considering the repayment of principal and interest
from the reporting date to the date of default, together with any expected drawdown of committed facilities.
Loss given default
(‘LGD’)
The proportion of the exposure that is expected to be lost in the event of default, taking account of the impact
of collateral and its expected value at the point of realisation, as well as recoveries and other means of loss
mitigation.
Models have been developed for all portfolios for the IFRS 9 ECL calculation. The overall modelling approach is aligned to the IRB
(internal ratings-based) regulatory capital models, amended to reflect differences in modelling requirements. For example, for
residential mortgage portfolios the IFRS 9 definition of default is based on arrears of 90 days past due, rather than 180 days past
due in the IRB models.
To calculate the lifetime ECL for a loan, separate 12 month ECL calculations are performed for each year of the loan’s expected life.
The outputs of these calculations for each year are then combined and discounted at the effective interest rate.
The PD, EAD and LGD inputs for the 12 month ECL calculations incorporate management’s expectations of future performance,
including forward looking economic assumptions. To reflect the uncertainty inherent in economic forecasting, multiple ECL
calculations are performed using different sets of assumptions (scenarios) that are considered possible. The provisions reported at
5 April 2018 incorporate the results of scenarios which have been weighted according to management’s assessment of their
likelihood.
Modelled ECL provisions may be adjusted by management if it is considered that they do not adequately reflect known credit risks,
for example, risks where there is insufficient historic loss data on which to develop models. Any such post model adjustments (PMAs)
are subject to thorough internal review before being applied.

Expected credit loss approach continued
Significant judgements and estimates
To ensure that ECL provisions fulfil IFRS 9 requirements, judgement and estimation is required in a number of areas. The areas
where the impact of judgement and estimation are most material are:
• the approach to applying the staging requirements
• the basis of forward looking information and multiple economic scenarios.
• the proportion of interest only mortgages that will redeem or refinance at maturity
• the period of exposure to credit risk for revolving loans.
Our approach to each of these judgements is described in more detail below.
Staging requirements
The calculation of an asset’s ECL will depend on the changes in its credit risk since it was originally recognised. The impact of
changes in credit risk on the calculation of ECLs is achieved using a three stage approach:
• an asset that is not credit impaired on initial recognition is classified in stage 1, with a loss allowance equal to 12 month
ECL,
• when a loan’s credit risk increases significantly, it will be moved to stage 2. The loss allowance recognised will be equal to
the loan’s lifetime ECL, and
• if a loan meets the definition of credit impaired, it will be moved to stage 3 with a loss allowance equal to its lifetime ECL.
A loan may remain in stage 1 for its entire life if there is no significant change in credit risk.
Identifying significant increases in credit risk (stage 2)
The identification of significant increases of credit risk is the most judgemental element of the staging criteria. Management regularly
monitors Nationwide’s loans to determine whether there have been changes in credit risk. This is assessed using quantitative and
qualitative indicators which vary depending on the nature of the portfolio and the information available. The primary quantitative
indicators are the outputs of internal credit risk assessments. For example, for retail exposures, PDs are derived using modelled
scorecards, which use external information such as information from credit reference agencies as well as internal information such
as known instances of arrears or other financial difficulty. While different approaches are used within each portfolio, the intention is
to combine current and historical data relating to the exposure with forward-looking macroeconomic information to determine the
likelihood of default.
The credit risk of each loan is evaluated at each reporting date by calculating the residual lifetime PD of each loan. For retail loans,
the main indicators for a significant increase in credit risk are either of the following:
• the residual lifetime probability of default (PD) exceeds a benchmark determined by reference to the maximum credit risk
that would have been accepted at origination
• the residual lifetime PD has increased by at least 75bps and a multiple of the original lifetime PD (8x for mortgages, 4x for
consumer banking).
These complementary criteria have been reviewed through detailed back-testing, and found to be more effective in capturing events
which would constitute a significant increase in credit risk (as determined by management performance indicators and actual
default experience) than either criterion individually.
For commercial loans, the main indicators for a significant increase in credit risk are either a significant change in the internal credit
rating of a loan as judged by risk management personnel, or transfer of a loan to a watchlist.
In addition, loans will automatically be moved to stage 2 when certain “backstop” events occur. This includes arrears of greater than
30 days past due and the granting of certain concession events such as forbearance, where full repayment of principal and interest
is expected.
Identifying credit impaired loans and the definition of default (stage 3)
The identification of credit impaired loans and the definition of default is another important judgement within the IFRS 9 staging
approach. A loan is credit impaired where it is considered unlikely that the borrower will repay its credit obligations in full, without
recourse to actions such as realising security. Loans will be classified as credit impaired in any of the following circumstances:
• a contractual payment is 90 days past due
• instances of bankruptcy, possession, litigation or the death of borrower
• a concession is granted which is not expected to lead to full repayment of principal and interest (eg interest suppression
for unsecured loans).
Nationwide Building Society – Report on Transition to IFRS 9

Expected credit loss approach continued
Reduction in credit risk
Loans in stage 2 or 3 can transfer back to stage 1 or 2 once the criteria for significant increase in credit risk or impairment are no
longer met, for example if arrears are cleared and if probability of default also reduces below the relevant quantitative threshold. For
loans subject to concession events such as forbearance, accounts must first be up to date for a period of 12 months before they can
transfer back to stage 1 or 2.
Use of forward looking economic information
Forward looking economic information is incorporated into the measurement of provisions in two ways: as an input to the calculation
of ECL and as a factor in determining the staging of an asset. Expectations of future economic conditions are incorporated through
modelling of multiple economic scenarios (MES).
The use of multiple economic scenarios ensures that the calculation of ECL captures a range of possible outcomes. It addresses the
risk of non-linearity in the relationship between credit losses and economic conditions, with provisions increasing more in
unfavourable conditions (particularly severe conditions) than they reduce in favourable conditions. The IFRS 9 ECL provision reported
in the accounts is therefore the probability-weighted sum of the provisions calculated under a range of economic scenarios.
For the retail and commercial portfolios, Nationwide has adopted the use of three economic scenarios (referred to as the central,
upside and downside scenarios). The scenarios and the weightings are derived using external data and statistical methodologies,
together with management judgement, to determine scenarios which span a wide range of plausible economic conditions. In
addition to the modelled scenarios, allowance has been made at 5 April 2018 for the risks associated with a low probability but
extremely severe economic downturn, since this is also a potentially material cause of non-linearity in credit loss outcomes.
The central scenario represents the most likely economic forecast and is aligned with the central scenario used in Nationwide’s
financial planning processes. The upside and downside economic scenarios are less likely. The table below provides a summary of
the average values of the key UK economic variables used within the central economic scenario over the period from April 2018 to
March 2023.
Central scenario economic variables
Average (%)
GDP 1.7
Unemployment 5.0
HPI 1.8
BoE Base Rate 0.9
The impact of the economic variables varies according to the portfolio. For example, mortgages are most sensitive to house prices
and base rates, whereas consumer banking products are more sensitive to unemployment rates.
Due to the adverse net impact of the less likely scenarios, the ECL increases under MES, as outlined in the table below:

Performance at maturity of interest only mortgages
The third key area of management judgement and estimation is the allowance for the risk that a proportion of interest only
mortgages will not be redeemed at the contractual maturity date, because a borrower does not have a means of capital repayment
or has been unable to refinance the loan. Buy to let mortgages are typically advanced on an interest only basis. Nationwide does not
offer any new advances for prime residential mortgages on an interest only basis, although there are historical balances which were
originally advanced as interest only mortgages or where a change in terms to an interest only basis was agreed (this option was
withdrawn in 2012). The impact of the adjustment in the central scenario amounts to £58 million, with an additional impact of £16
million arising from multiple economic scenarios (see above).
Interest only loans which are judged to have a significantly increased risk of inability to refinance at maturity are transferred to stage
2.
Expected lives
The final key area of estimation in calculating the ECL is in determination of the expected lives of revolving credit loans. For products
such as mortgages and personal loans, the period over which the Group is exposed to credit risk is the maximum contractual li fe.
However, for revolving credit loans such as credit cards and overdrafts, the Group is exposed to credit risk, including drawn and
undrawn facilities, beyond the typically short contractual notice period, so therefore the full expected behavioural life is taken into
account. Behavioural lives are based on empirical experience of revolving credit portfolios and are in excess of 10 years.
Other considerations in measuring changes in credit risk
Purchased or originated credit impaired (POCI) loans
POCI accounting is required for credit impaired loans purchased from third parties, or where the Group has derecognised an existing
credit impaired loan and then immediately restructured by the recognition of a new loan, where the new loan is also credit impaired.
The accounting treatment applied is to recognise a carrying amount at initial recognition net of the lifetime ECL at that date.
Thereafter, any subsequent change (favourable or unfavourable) in the lifetime ECL is recognised in the income statement. POCI
loans are separately disclosed as credit impaired loans and cannot be transferred out of the POCI designation, even if there is a
significant improvement in credit quality.
Modifications
Nationwide may on occasion modify the contractual terms of loans provided to members and other customers. When this is solely
for commercial reasons and considered part of the ordinary course of business, there is no impact on the impairment approach.
However, modifications can also be indicative of, or precipitate, changes in credit risk.
In some cases, the terms of a loan may be modified so significantly that it is substantially a different financial asset. Where this is
the case, the original loan is derecognised and a new loan is recognised in its place.
In most cases concerning residential mortgages, forbearance does not result in a recognition of a loss on a modified contract as the
revised contractual terms will continue to be interest bearing and will recover interest in full. In certain forbearance cases within
consumer banking some contractual interest may be suspended, however the impact is immaterial and no adjustment has been
made on transition to IFRS 9.
Write-off
Loans remain on the balance sheet net of associated provisions until they are deemed no longer recoverable, when such loans are
written off. Nationwide’s definition, assumptions and timing for write-off of loans have not changed with the adoption of IFRS 9.

Credit quality
The table below shows the loan balances and ECL for amortised cost residential mortgages by PD band. The PD distributions shown
are based on IFRS 9 12 month probability of default at the reporting date.
The ECL allocated to the lowest PD bands primarily reflects allocation of the provision for performance at maturity of interest only
mortgages.
Consumer banking stage 3 gross loans and ECL include charged off balances. These are in relation to accounts which are closed to
future transactions and are held on the balance sheet for an extended period (up to 36 months) whilst recovery procedures take
place.

Regulatory capital
Capital position and key ratios
The impact of the increase in IFRS 9 impairment provisions on the Common Equity Tier 1 (CET1) ratio at 5 April 2018 is a reduction
of 31 basis points. CET1 capital resources reduce by £67 million primarily due to increased impairment provisions and the impact of
the classification and measurement requirements, which are partly offset by the current excess of regulatory expected losses over
impairment provisions.
With effect from 5 April 2018, Nationwide will apply transitional arrangements, as permitted by EU Regulation (2017/2395), which
allows relief to capital ratios to reduce the impact of IFRS 9 ECLs. This is applied by adding back to CET1 capital resources, on a
reducing basis over the next five years, the impact of IFRS 9 ECLs and then adjusting any related deferred tax assets and Tier 2
provisions.
Following the application of these transitional arrangements, the reduction in the CET1 ratio is 10 basis points. The impact on the
UK leverage ratio is minimal. The implementation of IFRS 9 does not therefore have a significant impact on Nationwide’s capital
position.

Capital planning
The Group expects IFRS 9 ECL provisions to be more volatile and respond differently in terms of the business cycle (cyclicality and
procyclicality) than IAS 39 provisions. This will impact CET1 capital planning and will be taken into account in the capital strategy.
The impact of IFRS 9 has been included in the latest financial forecast and strategic plan that is approved by the Board. The Group
does not expect the implementation of IFRS 9 to result in any significant changes to strategic plans or Nationwide’s business model.
Capital adequacy
The management of Nationwide’s capital position is built on the foundations of the internal capital adequacy assessment process
(ICAAP) and stress testing framework. These ensure that the capital plan is sufficiently resilient to withstand the impact of severe
financial stress. The ICAAP and 2018 stress testing exercises currently underway have incorporated IFRS 9 ECL impairment
provisions to ensure that the impacts of IFRS 9 are taken into account.

Revised accounting policies
The Group’s full statement of accounting policies is disclosed within the 2018 Annual Report and Accounts. The policies for financial
assets and impairment of financial assets have changed from 5 April 2018 following the adoption of IFRS 9, and the revised policies
are set out below.
Financial assets
Financial assets comprise cash, loans and advances to banks, investment securities, derivative financial instruments and loans and
advances to customers.
Recognition and derecognition
All financial assets are recognised initially at fair value. Purchases and sales of financial assets are accounted for at trade date.
Financial assets acquired through a business combination or portfolio acquisition are recognised at fair value at the acquisition date.
Financial assets are derecognised when the rights to receive cash flows have expired or where the assets have been transferred and
substantially all the risks and rewards of ownership have been transferred.
The fair value of a financial instrument on initial recognition is normally the transaction price (plus directly attributable transaction
costs for financial assets which are not subsequently measured at fair value through profit or loss). On initial recognition, it is
presumed that the transaction price is the fair value unless there is observable information available in an active market to the
contrary. Any difference between the fair value at initial recognition and the transaction price is recognised immediately as a gain
or loss in the income statement where the fair value is based on a quoted price in an active market or a valuation using only
observable market data. In all other cases, any gain or loss is deferred and recognised over the life of the transaction, or until valuation
inputs become observable.
Modification of contractual terms
An instrument that is renegotiated is derecognised if the existing agreement is cancelled and a new agreement is made on
substantially different terms (e.g. renegotiations of commercial loans). Residential mortgages reaching the end of a fixed interest
deal period are deemed repricing events, rather than a modification of contractual terms, as the change in interest rate at the end
of the fixed rate period was envisaged in the original mortgage contract.
Classification and measurement
The classification and subsequent measurement of financial assets is based on an assessment of the Group’s business models for
managing the assets and their contractual cash flow characteristics. The Group has classified its financial assets into the following
3 categories:
(a) Amortised cost
Financial assets held to collect contractual cash flows and where contractual terms comprise solely payments of principal and
interest (SPPI) are classified at amortised cost. This category of financial assets includes cash, loans and advances to banks, the
majority of the Group’s residential and commercial mortgage loans, all unsecured lending, and certain investment securities within
a “hold to collect” business model.
Financial assets within this category are recognised on either the receipt of cash or deposit of funds into one of the Group’s bank
accounts (for cash and loans and advances to banks), or when the funds are advanced to customers (for residential, commercial
and unsecured lending). After initial recognition, the assets are measured at amortised cost using the effective interest rate method,
less provisions for expected credit losses.
(b) Fair value through other comprehensive income
Financial assets held in a business model whose objective is achieved by both collecting contractual cash flows and selling financial
assets, and where contractual terms comprise solely payments of principal and interest are classified and measured at fair value
through other comprehensive income (FVOCI). This category of financial assets includes most of the Group’s investment securit ies
which are held to manage liquidity requirements.
Financial assets within this category are recognised on trade date. The assets are measured at fair value using, in the majority of
cases, market prices or, where there is no active market, prices obtained from market participants. In sourcing valuations, the Group
makes use of a consensus pricing service, in line with standard industry practice. In cases where market prices or prices from market
participants are not available, discounted cash flow models are used.
Nationwide Building Society – Report on Transition to IFRS 9
18
Revised accounting policies continued
Interest on FVOCI assets is recognised in the income statement using the effective interest rate method. Unrealised gains and losses
arising from changes in value are recognised in other comprehensive income, except for foreign exchange gains or losses which are
recognised in the income statement and expected credit losses which are recognised in the income statement and accumulated in
the FVOCI reserve. Gains or losses arising on sale are recognised in the income statement, including the transfer of any cumulative
gains or losses, and net of the cumulative expected credit loss charge already recognised.
(c) Fair value through profit or loss
All other financial assets are measured at fair value through profit or loss (FVTPL). Financial assets within this category include
derivative instruments and a small number of residential and commercial loans and investment securities with contractual cash flow
characteristics which do not meet the SPPI criteria. The contractual terms for these cash flows include contingent or leverage
features, or returns based on movements in underlying collateral values such as house prices.
Fair values are based on observable market data, valuations obtained by third parties or, where these are not available, internal
models. All interest income and gains or losses arising from the changes in the fair value of these instruments and on disposal are
recognised in the income statement.
Financial assets which are classified as FVTPL are not eligible for hedge accounting.
Impairment of financial assets
Financial assets within the scope of IFRS 9 expected credit loss (ECL) requirements comprise all financial debt instruments measured
at either amortised cost or FVOCI. These include cash, loans and advances to banks, and the majority of investment securities and
loans and advances to customers. Also within scope are irrevocable undrawn commitments to lend and intra-group lending (the
latter being eliminated on consolidation in the Group accounts).
The ECL represents the present value of cash shortfalls following the default of a financial instrument or undrawn commitment. A
cash shortfall is the difference between the cash flows that are due in accordance with the contractual terms of the instrument and
the cash flows that the Group expects to receive.
The allowance for ECLs is based on an assessment of the probability of default, exposure at default and loss given default, discounted
at the effective interest rate to give a net present value. The estimation of ECLs is unbiased and probability weighted, taking into
account all reasonable and supportable information, including forward looking economic assumptions and a range of possible
outcomes. ECLs are typically calculated from initial recognition of the financial asset for the maximum contractual period that the
Group is exposed to the credit risk. However, for revolving credit loans such as credit cards and overdrafts, the Group’s credit risk is
not limited to the contractual period and therefore the expected life of the loan and associated undrawn commitment is calculated
based on the behavioural life of the loan.
For financial assets recognised in the balance sheet, the allowance for ECLs is offset against gross carrying value so that the amount
presented in the balance sheet is net of impairment provisions. For separable loan commitments where the related financial asset
has not yet been advanced, the provision is presented in provisions for other liabilities and charges on the balance sheet.
Forward looking economic inputs
ECLs are calculated by reference to information on past events, current conditions and forecasts of future economic conditions.
Multiple economic scenarios are incorporated into ECL calculation models. These scenarios are based on external sources where
available and appropriate, and internally generated assumptions in all other cases. To capture any non-linear relationship between
economic assumptions and credit losses, a minimum of three scenarios is used. This includes a central scenario which reflects the
Group’s view of the most likely future economic conditions, together with an upside and downside scenario representing alternative
plausible views of economic conditions, weighted based on management’s view of their probability.

Revised accounting policies continued
Stage 1: 12 month expected credit losses
On initial recognition, and for financial assets where there has not been a significant increase in credit risk since the date of advance,
provision is made for losses from credit default events expected to occur within the next 12 months. Expected credit losses for these
stage 1 assets continue to be recognised on this basis unless there is a significant increase in the credit risk of the asset.
Stage 2: significant increase in credit risk
Financial assets are categorised as being within stage 2 where an instrument has experienced a significant increase in credit risk
since initial recognition. For these assets, provision is made for losses from credit default events expected to occur over the lifetime
of the instrument.
Whether a significant increase in credit risk has occurred is ascertained by comparing the risk of default at the reporting date to the
risk of default at origination, and is made based on quantitative and qualitative factors, with a backstop indicator. Quantitative
considerations take into account changes in the residual lifetime PD of the asset. As a backstop, assets with an arrears status of
more than 30 days past due on contractual payments are considered to be in stage 2.
Qualitative factors that may indicate a significant change in credit risk include concession events that still envisage full repayment
of principal and interest, or downgrades to external credit ratings.
Stage 3: credit impaired (or defaulted) loans
Financial assets are transferred into stage 3 when there is objective evidence that an instrument is credit impaired. Provisions for
stage 3 assets are made on the basis of lifetime expected credit losses. Assets are considered credit impaired when:
• contractual payments of either principal or interest are past due by more than 90 days;
• there are other indications that the borrower is unlikely to pay such as signs of financial difficulty, probable bankruptcy,
breaches of contract and concession events which have a detrimental impact on the present value of future cashflows; or
• the loan is otherwise considered to be in default.
Interest income on stage 3 credit-impaired loans is recognised in the income statement on the loan balance net of the ECL provision.
The balance sheet value of stage 3 loans reflects the contractual terms of the assets, and continues to increase over time with the
contractually accrued interest.
Purchased or originated credit impaired (POCI) loans
Where loans are credit impaired on origination, or when purchased from third parties, the carrying amount at initial recognition is
net of the lifetime ECL at that date. Thereafter, any subsequent change (favourable or unfavourable) in the lifetime ECL is recognised
in the income statement. POCI loans are separately disclosed as credit impaired loans and cannot be transferred out of the POCI
designation, even if there is a significant improvement in credit quality.
Transfers between stages
Transfers from stage 1 to 2 occur when there has been a significant increase in credit risk and from stage 2 to 3 when credit
impairment is indicated as described above.
For assets in stage 2 or 3, loans can transfer back to stage 1 or 2 once the criteria for significant increase in credit risk or impairment
are no longer met. For loans subject to concession events such as forbearance, accounts must first be up to date for a period of 12
months before they can transfer back to stage 1 or 2.
Write-off
Loans remain on the balance sheet net of associated provisions until they are deemed no longer recoverable. Where a loan is not
recoverable, it is written off against the related provision for loan impairment once all the necessary procedures have been completed
and the amount of the loss has been determined. Subsequent recoveries of amounts previously written off decrease the value of
impairment losses recorded in the income statement.

Glossary
This Glossary provides definitions of additional terms relevant to IFRS 9. All other definitions are set out in the Glossary for the Annual
Report and Accounts 2018 available at nationwide.co.uk/about/corporate-information/results-and-accounts
Expected Credit Loss (ECL) The present value of all cash shortfalls over the expected life of the financial instrument.
The term is used for the accounting for impairment provisions under the new IFRS 9
standard.
ECL – 12 Month Cash shortfalls resulting from default events that are possible in the next 12 months
weighted by the probability of that default occurring.
ECL – lifetime Cash shortfalls resulting from default events that are possible over the remaining
expected life of the loan, weighted by the probability of that default occurring.
Fair Value through other
comprehensive income (FVOCI)
Financial assets held at fair value on the balance sheet with changes in fair value
recognized through other comprehensive income.
Fair value through profit or loss
(FVTPL)
Financial assets held at fair value on the balance sheet with changes in fair value being
recognized through the income statement.
Non-linearity Non-linearity in the relationship between ECLs and economic conditions occurs when a
change to an economic assumption or scenario has a greater effect on the level of credit
losses, when compared to an equivalent change in the assumption or scenario in the
opposite direction.
Probability of Default (PD)
An estimate of the probability that a borrower will default on their credit obligations over
a fixed time period. A 12 month ECL uses a 12 month PD, whilst a lifetime ECL uses the
estimated PD over the remaining contractual life of the loan.
Purchased or originated credit
impaired assets (POCI)
POCI loans are credit impaired when initially recognised on the balance sheet, either if
purchased when impaired from a third party, or if recognised as a new loan (eg through
restructuring of an existing credit impaired loan).
Significant increase in credit risk A significant increase in credit risk on a financial asset is judged to have occurred when
an assessment, using quantitative and qualitative factors, identifies at a reporting date
that the credit risk has moved significantly since the asset was originally recognised.
SPPI test An assessment of whether the contractual terms of the financial asset give rise to cash
flows that are in substance solely payments of principal and interest.
Stage 1 Stage 1 assets are assets which have not experienced a significant increase in credit risk
since the asset was originally recognised on the balance sheet. 12 month ECL are
recognised as the impairment provision for all financial assets on initial recognition.
Interest revenue is the EIR on the gross carrying amount.
Stage 2 Stage 2 assets have experienced a significant increase in credit risk since initial
recognition. Lifetime ECL is recognised as an impairment provision. Interest revenue is
the EIR on the gross carrying amount.
Stage 3 Stage 3 assets are identified as in default and considered credit impaired. Lifetime ECL
is also recognised as an impairment provision. Interest revenue is the EIR on the net
carrying amount.
