Product Overview
Covered bonds: a ‘bluffer’s guide’
We set out below a cheat-sheet for readers new to the asset class, providing a
synopsis of the main characteristics of the product.
Table 1: Covered bond cheat-sheet
What is a covered bond? Covered bonds are secured, senior, bullet instruments of an issuer (typically a bank), that provide investors
with recourse to both the issuing institution and the underlying revolving collateral pool.
What types of CB structures exist? There are three broad CB structures: a) CB can be issued directly off the balance sheet of the originator, with
the collateral pool remaining with the originator, albeit ring-fenced for covered bond investors (for example, in
Austria and Germany); b) a financial institution establishes a limited function subsidiary, which in turn issues
covered bonds (for example, France’s OF, Norway, Ireland etc); c) in structured CB jurisdictions, CBs are
typically unsecured obligations of the issuer, with funds raised from the issuance of CB lent to a guarantor
vehicle (typically a limited liability SPV), which uses the loaned amounts to acquire collateral from the
originator. This collateralised entity then acts as guarantor to the unsecured bonds, agreeing to repay
bondholders on insolvency of the issuer (for example UK, Canada, Netherlands, Italy).
What type of collateral is accepted? CB legislation (or transaction docs, when no CB legislation exists) typically define the list of collateral eligible
to be included in the cover pool. The main types of assets used as primary collateral are public sector
exposures and residential & commercial mortgages. Shipping, aircraft and SME exposures are also able to
be included in some jurisdictions. In some cases, a max LTV is specified. The EC’s CRR also allows senior
MBS (both residential and commercial) issued by securitisation entities, where at least 90% of the underlying
mortgages comply with the above rules for unsecured mortgage exposures (essentially when securitisation is
used for intra-group asset transfer). The MBS must be rated Credit Quality Step 1 (AAA to AA-) and can only
form 10% of the collateral pool (self-originated MBS receive a waiver from the 10% cap). Substitute assets
up to a given threshold (typically 10-15%) can also be included in cover pools, and typically include public
sector or bank exposures (and cash).
What type of risk are investors exposed to? Investors are generally exposed to issuer risk until its default, after which they are exposed to the credit risk
of the cover pool. If there are CBs outstanding after the cover pool has been extinguished, CB investors will
have a residual claim to the bankruptcy estate of the issuer which will rank pari passu with that of senior
unsecured bondholders
Do cover bonds accelerate upon the issuer’s default? No, CBs do not necessarily accelerate on insolvency of the issuing institution. Only the failure of the
programme to make payments as and when due typically results in the acceleration of the obligations.
Which jurisdictions are the largest markets? The largest market, by outstanding amount, is Denmark, followed by Germany, France and Spain. As CBs
gain popularity with regulators, issuers and investors, more jurisdictions are starting to push for dedicated
covered bond legislation. Singapore launched its inaugural benchmark covered bond in July 2015, while
Turkey and Poland debuted in April 2016 and October 2016, respectively. Most recently, the inaugural
benchmark covered bond from Japan was issued in October 2018, followed by Slovakia in March 2019.
How do CBs differ from RMBS? The main differences between RMBS and covered bonds can be summarised as:
a) amortisation: RMBS generally have a pass-through structure based on the repayment of the underlying
collateral, while CBs generally have a hard (or soft) bullet profile–although ‘hybrid’ instruments, known as
Conditional pass-through (CPT) bonds have become increasingly popular; b) credit enhancement: covered
bonds have much simpler structures than ABS and rely on over-collateralisation as the predominant form of
credit enhancement. This can vary according to the usage of the programme by the issuer but a minimum
OC has to be maintained; this is monitored through asset and interest coverage tests typically monitored by
third parties, which ensure that the asset pool and its proceeds are enough to match the issuer’s CB
liabilities. In senior RMBS, credit enhancement is given by both subordination and structural features and,
except for certain structures, it generally increases as the deal de-levers; c) unlike securitisation, where
investors benefit from recourse to the collateral pool only, CB investors benefit from dual recourse to both
the issuer and the cover pool.

Below, we set out to define the core characteristics of the covered bond product,
despite recognising that by making some generic statements, we ignore some of the
multiple nuances that issuance from a number of issuers and jurisdictions necessarily
implies. We update this segment to reflect changes to legislative frameworks and the
rating methodologies of the main agencies.
For more detail on individual jurisdictions, please see the respective country sections
towards the back of this publication.
What exactly is a covered bond?
In a sentence…
Covered bonds are secured, senior, bullet instruments of an issuer (typically a bank),
that provide investors with recourse to both the issuing institution and the underlying,
revolving collateral pool.
Structural form
Covered bonds are typically thought of as bonds issued from the balance sheet of an
originating bank, with the revolving collateral pool remaining with the originator,
albeit ring-fenced for covered bond investors in case of institutional insolvency. This
model is deployed in a number of significant issuing jurisdictions (for example,
Austria, Finland, Germany, Greece, Portugal, Spain and Sweden); however, there are
also two other forms of covered bond structures common in a number of
jurisdictions.

The most simplistic alternate structure can be accurately described by its name:
‘Specialist Banking Principle’, whereby a ‘full service’ financial institution
establishes a limited function subsidiary, which in turn issues the covered bonds,
backed by assets transferred from the originator. This form is typical in Ireland, and
France (for Obligations Foncière), Hungary, Luxembourg and Norway.
The third variation on issuance form tends to have been adopted by the Anglo-Saxon
jurisdictions (Australia, Canada, New Zealand and the UK) along with Italy, the
Netherlands and Switzerland. This structure was typically adopted initially by
countries that did not benefit from specific covered bond legislation, but rather
adopted securitisation techniques to create a covered bond investment (Figure 2). A
growing number of these jurisdictions (the UK, Canada, New Zealand, Australia),
however, have been cementing such structures into a legislative framework.
Figure 2: Example structured covered bond diagram
Source: . Morgan International ABS & CB Research
Under this approach, covered bonds are actually unsecured obligations of the issuer.
Funds raised from the issuance of covered bonds are then on-lent to a guarantor
entity (typically a limited liability SPV), which uses the loan to acquire collateral
from the originator. This entity then acts as guarantor to the unsecured bonds,
agreeing to repay bondholders on insolvency of the issuer.
Market participants often refer to ‘legislative’ and ‘structured’ covered bond markets,
distinguishing between the first two forms described above and the latter (although
these terms can be something of a misnomer since ‘structured’ markets now also
have legislation).
Recourse & seniority
Covered bond investors benefit from dual recourse, whereby they have recourse to
both the collateral pool backing the specific programme as well as a shortfall claim to
the estate of the originator on its default. Securitisation investors on the other hand
have recourse only to the collateral pool.
Covered bonds remain the obligation of the issuing institution prior to its default,
similar to any unsecured obligation and irrespective of the collateral performance in
the cover pool (non-payment of a covered bond typically constitutes a default of the
institution). Only after an institution’s default does the primary source of programme
payments switch to the cover pool itself. Subsequently, should the pool prove

insufficient to repay all outstanding obligations under the programme, covered bond
investors will have further recourse to the bankruptcy estate of the issuer. These
residual claims would rank pari passu with those of other senior (unsecured)
bondholders.
Collateral
Covered bond legislation typically defines the list of collateral eligible to be included
in a cover pool. The main types of assets used as primary collateral (substitute assets
are also eligible in cover pools up to a pre-defined threshold, typically 10-15%) are
mortgages (both residential and commercial), and public-sector exposures. Finally,
shipping and aircraft loans can also be used as collateral – but remain minor parts of
the market. As the product expands its geographic reach beyond its traditional home
in Europe, the list of eligible (primary) assets may also expand.

In the EU, the primary source of guidance is provided in Article 129 of the Capital
Requirements Regulation1 (CRR), which sets out the following:
Exposures to or guaranteed by public sector entities (central governments, central
banks, PSEs, regional governments and local authorities) in the EU.
Exposures to or guaranteed by third country public sector entities (central
governments, central banks, MDBs, international organisations, PSEs, regional
governments and local authorities qualifying as Credit Quality Step 1).
Exposures falling into Credit Quality Step 2 cannot exceed 20%.
Exposures to institutions qualifying as Credit Quality Step 1, not to exceed 15%,
or Credit Quality Step 2 with a maturity <100 days.
Residential (80% LTV limit) and commercial mortgage loans (60% LTV limit, or
70% if an issuer provides a minimum of 10% over-collateralisation).
Senior MBS (both residential and commercial) issued by securitisation entities,
where at least 90% of the underlying mortgages comply with the above rules for
unsecured mortgage exposures. The MBS must be rated Credit Quality Step 1,
and can form only 10% of the collateral pool. For the 10% limit to be waived, the
MBS must be self-originated and the originator must retain the first loss piece.
Loans secured by ships (60% LTV limit).

Derivatives are also permitted in certain jurisdictions to hedge specific risks,
including interest and foreign exchange exposures.
Cover pools backing covered bonds are dynamic in nature, with investors essentially
assuming the credit risk of the cover pool only upon issuer default.
Insolvency
Covered bonds do not necessarily accelerate on insolvency of the issuing institution.
Only the failure of the programme to make payments as and when due results in the
acceleration of the obligations.
Regulatory update
Covered Bonds Package (including the Directive and the Regulation)
In March 2018, the European Commission published a legislative proposal for a
Covered Bond Directive, with the aim of establishing a minimum harmonisation
framework for EU covered bonds (recognising the disparate nature of national
covered bond frameworks), as well as a related amendment to the Capital
Requirements Regulation (CRR); together, these are known as the ‘Covered Bonds
Package’. Following the initial publication of a draft report on the Commission’s
proposal by lead MEP, or Rapporteur, Bernd Lucke in August 2018 and subsequent
compromise amendments in October, the European Parliament’s Economic and
Monetary Affairs (ECON) Committee adopted the draft report on the Covered Bonds
Package in November 2018.
Most recently, after relatively brief trilogue negotiations between the European
Commission, the European Council, and the European Parliament which began in
late January 2019, the European Parliament’s ECON Committee adopted the final
agreement on the Covered Bonds Package in April 2019 (see here for the adopted
text on the Directive and the Regulation). At present, it is anticipated that the
agreement will be published in the Official Journal of the EU in late 2019, with
adoption by Member States intended 18 months after publication (in H1 2021) and
full application 12 months later (in H1 2022).
Though there are many aspects of the Covered Bond Directive that are intended to
define an EU-wide, harmonised covered bond framework, we summarise some of the
most basic aspects of the agreement below. We note that while the Directive provides
guidance and minimum standards for EU covered bond issuance, the framework
leaves considerable scope for interpretation, specification, and refinement by
individual Member States. Key highlights of the Covered Bond Directive include:
Defining the required characteristics of a covered bond as “a debt obligation
issued by a credit institution in accordance with the provisions of national law
transposing the mandatory requirements of this Directive and secured by cover
assets to which covered bond investors have direct recourse as preferred
creditors;”
Establishing that both covered bond investors and derivative counterparties are
entitled to dual recourse, including (in case of issuer insolvency) a claim on the
cover assets and, if that is insufficient, a claim on the insolvency estate of the
issuer that is pari passu with unsecured creditors;
Covered bonds must be bankruptcy remote, and not automatically accelerate
upon insolvency of the issuer;
The Covered Bond Directive, which
will likely apply from H1 2022,
establishes an EU-wide, harmonised
covered bond framework

Defining eligible assets within a cover pool, which in part recalls Article 129(1)
of the CRR (outlined in its current form above, and select amendments below).
Physical collateral assets that fall outside the scope of Article 129 are subject to
an LTV limit of 70%, while covered bonds backed by public sector assets are
subject to minimum overcollateralisation (OC) of 10%;
At the discretion of individual Member States, collateral assets located outside of
the EU can be included in the cover pool, subject to security and enforcement
requirements (similar or equivalent to the standard in the EU);
Creates two categories of covered bonds, including ‘Premium’ and ‘Ordinary’
European Covered Bonds, where ‘Premium’ covered bonds comply with the
requirements of Article 129 of the CRR.
Permitted use of derivatives in the cover pool, solely for hedging risk;
Establishes minimum standards for required segregation of cover pool assets;
Transparency for investors via reporting requirements (to be provided at least
quarterly);
Cover pools must contain a liquidity buffer of sufficient liquid assets (including
HQLA Level 1, 2A, or 2B assets, or short-term exposures or deposits to
sufficiently highly-rated credit institutions) to cover “the maximum cumulative
net liquidity outflow for 180 calendar days;”
Extendable maturity structures are permitted, with ”objective” extension triggers
defined by national law rather than at the issuer’s discretion, and where maturity
extensions do not affect the ranking of covered bond investors in the event of
issuer insolvency;
No immediate 3rd country equivalence, but with a provision to be reviewed in a
report and potential legislative proposal by the European Commission and the
EBA, falling 2 years from the application of the Directive;
Further reports on extendible maturity structures and the potential development of
a new product, European Secured Notes (backed by riskier assets such as SME
exposures), to also be published 2 years from the application of the Directive.
Moreover, key points of the related amendments to the CRR include:
In terms of acceptable cover pool collateral for covered bonds to receive
preferential capital treatment (as outlined in Article 129), included will be short-
term exposures (maturity of less than or equal to 100 days) and derivative
contracts to credit institutions that qualify for CQS 3. The short-term exposures
and derivative contracts to CQS 3 institutions are capped at 8% of an issuer’s
total exposure of the nominal amount of covered bonds outstanding (total of
exposures to CQS 2 and CQS 3 institutions capped at 10%);
The 80% LTV limit for residential mortgages under Article 129 will be applied
on a loan-by-loan basis. Additionally, the 60% or 70% LTV limit (depending on
sufficient overcollateralisation) for commercial property and 60% for ship loans
will also be applied on a loan-by-loan basis. To this end, ship loans will be also
subject to the same requirements as immovable property, as outlined in Article
208 of the CRR.
Sets a minimum 5% overcollateralisation (OC) requirement, though individual
Member States have discretion to lower this threshold (but not below 2%).
However, outstanding covered bonds that were issued before the date of

application of the amended Regulation are not subject to this overcollaterisation
requirement, and can continue to receive preferential capital treatment through
maturity.
Covered bonds vs. RMBS
Mortgage-backed covered bonds and RMBS have more than a passing similarity to
each other. However, there are also some notable structural differences between the
two products. We set out to highlight the most prominent below.
Definitions
The ECBC2 sets out a definition of a covered bond as having the following essential
features that are achieved under either a special-law or general-law based
framework.:
The bond is issued by, or bondholders have full recourse to, a credit institution
which is subject to public supervision and regulation;
Bondholders have a claim against a cover pool of financial assets in priority to
the unsecured creditors of the credit institution;
The credit institution has the ongoing obligation to maintain sufficient assets in
the cover pool to satisfy the claims of covered bondholders at all times; and
The obligations of the credit institution in respect of the cover pool are supervised
by public or other independent bodies.
More fully, the BIS sets out a definition of securitisation in its ‘International
Convergence of Capital Markets and Capital Standards’3 document:
‘A traditional securitisation is a structure where the cash flow from an underlying
pool of exposures is used to service at least two different stratified risk positions or
tranches reflecting different degrees of credit risk. Payments to the investors depend
upon the performance of the specified underlying exposures, as opposed to being
derived from an obligation of the entity originating those exposures.’
As we can see from the above BIS definition, covered bonds fail to meet this test on
a number of fronts. First, as we have already noted, cashflows from the underlying
pool are not necessarily used to service the covered bonds, but rather the general
resources of the issuing institution are utilised. Second, as such there are no stratified
risk positions or tranches reflecting different credit risk profiles in covered bonds.
Finally, payments to investors do not depend on the performance of the underlying
exposures while the issuing entity remains solvent. The credit risk of the cover pool
is not transferred until issuer insolvency.

Amortisation
European securitisation bonds typically amortise over time through the repayment of
the underlying exposures (a notable exception to this are UK credit card and UK and
Dutch mortgage master trusts, which offer investors soft-bullet bonds). Distributed
covered bonds typically utilise a hard or soft-bullet redemption profile (there are
some pass-through covered bonds, but these have typically been retained by
originators for use as central bank repo collateral). Increasingly however, ‘hybrid’
instruments known as Conditional Pass-Through (CPT) bonds are being used, which
combine a scheduled soft-bullet maturity, with a pass-through 'tail' following
institutional default.
Credit enhancement & Investor protections
Covered bonds are less structurally engineered than even the simplest type of pass-
through securitisation vehicles (even setting aside the complexities of ABS master
trusts). To this end, covered bonds do away with much of the credit enhancement
offered to securitisation investors (subordinated tranches, reserve funds, excess
spread, etc). Rather, covered bond investors’ main form of credit enhancement stems
from programme over-collateralisation (which is naturally dynamic based on issuer
actions, including collateral additions and the programme’s issuance/redemption
profile). Unlike in securitisations, where credit enhancement tends to increase over
time as the structure delevers (barring collateral credit issues and the specific case of
master trusts), over-collateralisation in covered bond programmes can increase or
decrease as the programme is utilised by the issuer.
Further investor protection is provided to CB investors by tests adopted in local
legislation or programme terms. For example, ‘structured’ covered bond programmes
(. Canada, the Netherlands, the UK, etc) typically require that the assets of the
guarantor entity are subject to an Asset Coverage Test (ACT) on a regular basis. The
test is designed to ensure a minimum level of over-collateralisation in the cover pool
to protect investors from market and liquidity risks. The guarantor must therefore
ensure that on each calculation date, the ‘Adjusted Aggregate Loan Amount’ (. the
aggregate loan amount haircut by predefined criteria) is at least equal to the
outstanding amount of the programme’s CB. The ACT is conducted by the Cash
Manager, with annual third-party asset monitor reviews. Failure to remedy a
breached ACT by the next calculation date usually results in an Issuer Event of
Default.
Similarly, programmes from these jurisdictions also typically include an
Amortisation Test (AT), which is designed to ensure that the cover pool exceeds the
outstanding notional of CB at all times. The adoption of an AT serves to minimise
time subordination within the structure for outstanding noteholders. Following
service of a Notice to Pay on the guarantor, it must ensure that on each calculation
date following an Issuer Event of Default, the Amortisation Test Aggregate Loan
Amount will at least equal the aggregate outstanding amount of the CB.
Other tests offering protection to bondholders include ‘Pre-maturity Tests’ (which
are designed to ensure the borrower can provide sufficient liquidity in case of
downgrade (. pre-defined period prior to scheduled bond redemption, if a
borrower’s short-term rating is below a prescribed threshold, the borrower must fund
a cash collateral account to ensure redemption)); and ‘Interest Coverage Tests’ to
ensure interest from the cover pool after hedges always exceed interest payments due
on the covered bonds over a given period.

Market statistics
ECBC data as at the end of 2018 shows that the aggregate volume of covered bonds
outstanding totals nearly €, of which the majority (%, see Figure 3) is
backed exclusively by mortgage assets. This represents a YoY growth rate of nearly
5%, or net issuance of € during 2018 (we estimate net issuance of benchmark
bonds was €66bn). The five largest markets by outstanding volume, which are led by
Denmark at €406bn and Germany at €370bn, account for € of bonds, or 60%
of all outstanding covereds (while the top 10 countries, at €, account for 84%
of all bonds).

Splitting the two most significant collateral types, we see from Figure 6 that
Denmark is the largest mortgage covered bond jurisdiction, with €396bn of bonds
outstanding as at the end of 2018, although much of the Danish product is issued in
both the domestic currency and non-benchmark format – predominantly finding a
home with the local investor base. Second is Germany, with €233bn of mortgage
covered bonds outstanding, while Sweden, Spain, and France take up the next three
spots at €218bn, €213bn, and €194bn of outstanding mortgage-backed covered
bonds, respectively.

Turning to public sector-backed covered bonds, Figure 7 shows that Germany
dominates the product at €135bn, or 51% of outstanding volume. While still
meaningful in terms of outstanding volumes, this represents a smaller balance than
year-end 2017 (€148bn), with net issuance of -€13bn in 2018.

Finally, considering new issuance volume, the ECBC calculates that €500bn of
bonds were issued in 2018, up 12% vs. the €446bn issued in 2017, of which 94%
were backed by mortgages (Table 3). Denmark, with its unique mortgage funding
model, led the way at €119bn of bonds, but as previously noted, this balance is
overwhelmingly DKK-denominated. Sweden, Germany, and Italy take the next 3
spots, though the majority of Swedish bonds are also denominated in the local
currency, while most Italian supply was privately placed. For benchmark investors,
Germany, France, and Canada were the largest providers of new supply in FY 2018.

Rating agency approaches
We set out below an overview of the ratings approaches adopted by the four agencies
with respect to covered bonds. All four agencies link the rating of covered bonds to
the rating of the issuing bank, providing further scope for uplift from the issuer rating
based on both collateral and cover pool cashflow characteristics.
DBRS
The following is our synopsis of the methodology used by DBRS to rate covered
bonds. For a complete overview of the Agency’s approach, please see Rating and
Monitoring Covered Bonds, published in June 2019.
DBRS sees covered bonds as being akin to senior secured bank debt, therefore
deploys a ‘linked approach’ to its ratings methodology. The ratings process is built
around four building blocks:
Covered Bond Attachment Point (CBAP). Since the issuer is the primary
source of timely payment and ultimate repayment of a programme’s outstanding
covered bonds prior to institutional default, the basis for the CBAP is either the
senior unsecured rating of the issuer or the Critical Obligations Rating.
Legal and Structuring Framework (LSF) and LSF-implied Likelihood (LSF-
L). This assessment is the most significant of the four building blocks, and
involves the evaluation of the level of delinkage between the issuer itself and the
covered bond programme. The five LSF assessments range between Modest and
Very Strong, and primarily involve the review of the national legislative
backdrop, and the contractual framework and terms of the programme. By
combining the LSF (to determine the applicable ratings matrix), and using the
CBAP and CP Credit Assessment (next step), the LSF-L can be identified. The
CBAP serves as the floor for the LSF-L. We show the ‘Average’ LSF matrix in
Table 4.
CP Credit Assessment. Credit analysis of the cover pool, the expected cashflows
from hedging and other transaction counterparties, and various stresses (.
interest rate and currency stress) form part of a multi-scenario cash flow anaylsis,
with the objective to test the receipt of timely interest and full principal at the
maturity date of the covered bond.
High Recovery Prospects provided by the CP. Grants up to an extra two
notches from the LDF-L if the CP analysis shows it would provide substantial
support following the default of its covered bonds.
All agencies generally use the
unsecured rating of the issuer as a
rating’s floor for its covered bonds

Fitch Ratings
The following is our synopsis of the methodology used by Fitch Ratings to rate
covered bonds, which was updated in July 2019. For a complete overview of the
Agency’s approach, please see Fitch Ratings’ Covered Bond Rating Criteria,
published on 24th July 2019.
First, the issuing institution’s Issuer Default Rating (‘IDR’) forms the starting point
of the covered bond rating. In situations where an issuing subsidiary is likely to be
supported by the parent in the face of financial difficulties, or if the assets of the
issuing entity are comprised only of advances granted to the parent and secured
against the cover assets, Fitch will utilise the Long-Term IDR of the parent, known
as the “reference IDR”. Furthermore, in instances where the covered bonds are
guaranteed by a rated third party, Fitch will use the higher or the guarantor’s Long-
Term ID or the issuer's IDR. Finally, for cases where the IDR or reference IDR is
below ‘B-‘, Fitch will set the floor for the covered bond rating at the higher of: ‘B-‘,
the IDR plus IDR uplift, or one-notch above the rating of the Derivative Couterparty,
provided it expects that recourse will not switch to the cover pool in the event of a
default on senior unsecured debt. However, in instances where recourse to the cover
pool is expected in the event of an issuer default (when IDR is below ‘B-’), the rating
agency will not set a rating floor.
To recognise the introduction of the BRRD regime in many jurisdictions, whereby an
institution may default on its senior unsecured obligations while maintaining
payments to its covered liabilities, it is possible to use an IDR with an uplift given
covered bonds’ favourable position compared to unsecured senior investors. In this
situation, the uplifted IDR becomes the floor for the covered bonds’ rating. An IDR
uplift of up to two notches can be used in covered bond jurisdictions with advanced
bank resolution regimes in place, that includes bail-in for senior unsecured liabilities,
(but not for covered bonds), and where enforcement will not be made against the
cover pool. Furthermore, an IDR uplift may only be applied to programmes seen as
having a sufficiently low risk of undercollateralisation at the point of resolution.

A maximum IDR uplift of two notches can be assigned to programmes from issuers
with a Viability Rating (VR)-driven IDR, those from institutions whose IDR is based
on participation in a mutual support scheme, those from institutions receiving
temporary liquidity support which have an IDR above the Viability Rating, and
Support Rating of '5' and a Support Rating Floor of 'No Support', and those from
issuers with a support-driven IDR that are integrated with a parent bank whose IDR
is not support-driven; programmes from certain other institutions with a support-
driven IDR may be eligible for a one notch uplift, while programmes from small,
independent issuers and standalone specialised lenders will not benefit from any
uplift.
The second step involves determining the maximum achievable covered bond rating
by determining the applicable Payment Continuity Uplift (PCU), which reflects the
extent to which covered bonds are protected from payment interruption upon the
enforcement of recourse to the cover pool. This Payment Continuity Uplift serves as
a replacement for the old discontinuity cap (D-Cap) analysis that formerly comprised
this step of the rating process.
The PCU is expressed as an uplift above an issuer’s adjusted IDR, and ranges
between 0 and 8 notches. The main driver of the PCU is liquidity, and Fitch assesses
the degree of liquidity protection provided through legal requirement or contractual
provisions. Pass through programmes, where the maturity date extends beyond the
longest maturing asset in the cover pool, benefit from the maximum PCU of 8
notches, while mortgage and public sector programmes predominantly exposed to
developed banking markets can receive a PCU between 3 and 6 notches, depending
on the duration of effective liquidity protection for principal payments (6, 9, or 12
months). No uplift is given to programmes exposed to maturity mismatches.
At this stage, the Agency also carries out a recovery given default analysis, which
can result in further uplift to the Maximum Achievable Rating. The maximum
recovery uplift can be 2 notches for programmes with an investment grade tested
rating on a PD basis (which is determined via a cash flow stress test, described
below) and 3 notches for a non-IG tested rating.

The last step involves assessing the highest level of stress that the over-
collateralisation in the cover pool can withstand while still maintaining timely
interest and principal payments in a stress scenario. The pool is assessed under
economic downturn conditions, and compares the stressed cashflows from the cover
pool to the payments required to be made on the covered bonds themselves. Over-
collateralisation is key to the rating since it is the main form of credit-enhancement
available to covered bond investors.
Fitch applies stress scenarios covering credit losses and prepayment of the assets,
servicing and management fees, refinancing spreads and negative carry-cost
assumptions, and movements in interest and foreign exchange rates. In essence,
there are two main sources of risk which are evaluated to assess the timely payment
of covered bonds in these scenarios. The first is the credit loss, which reflects the

credit risk of the cover assets, and the second is the ALM loss, which relates to the
asset-liability mismatch between the cover assets and covered bonds. The results of
the stress tests give the breakeven OC (or Asset Percentage), which is the minimum
OC or AP required to support timely payment in a stressed scenario for a given
covered bond rating.
Fitch gives credit for over-collateralisation in the following order: legal and
contractual commitments, if legally binding and enforceable; non-contractual public
statements and/or covenants; and the lowest level of over-collateralisation during the
last twelve months (for institutions rated at least ‘F2’ and the programme is not in
wind-down or dormant). For issuers rated F3 or below or programmes in wind-down
or dormant, Fitch gives credit for the minimum level of over-collateralisation
required by legislation.
Fitch also notes that it will assign limited or no ratings uplift above an issuer’s IDR
for programmes that have limitations in available cover pool assets, cash flows, or
market information.
Moody’s
The following is our synopsis of the methodology used by Moody’s to rate covered
bonds. For a complete overview of the agency’s approach, please see Moody’s
Approach to Rating Covered Bonds, published in February 2019.
Moody’s covered bond rating methodology follows a two stage process:
First, the Agency applies a quantitative model, called the Expected Loss
Covered Bond Model (‘EL model’) which produces a maximum potential
rating for an institution's covered bonds based on a combination of the
probability that the issuer will cease making payments under the covered
bonds (‘a CB anchor event’) and the estimated losses that would accrue to
the cover pool after the CB anchor event.
Second, they adjust the maximum potential rating from the EL model to
account for certain risks such as refinancing risk following the CB anchor
event, via the Agency's Timely Payment Indicator (‘TPI’). The TPI in effect
limits the uplift above the CB anchor, potentially constraining the maximum
rating under the EL model.
The EL model looks to capture the value of the cover pool following a CB anchor
event, which in turn will be driven by the collateral pool’s credit quality, refinancing
risk and any interest-rate or currency mismatches between the assets and liabilities of
the covered bond structure (the latter two combining to be termed ‘market risk’).
The model looks at a covered bond on a monthly basis, estimates the probability of a
CB anchor event occurring in each period and the loss to the covered bond following
such an anchor event. The probability of a CB anchor event in each period is
multiplied with the relevant loss for that month, and these values are then discounted
back and aggregated to arrive at the expected loss amount for the programme. The
probability of a CB anchor event happening is based on the probability of the issuer
failing to meet its obligations, or the Counterparty Risk (CR) Assessment of the
issuer. The CB anchor, may in fact be either the CR, or the CR+1 rating notch in
situations where the local bank resolution regime is expected to prioritise the
continuity of covered bond payments.

The Value of the Cover Pool is determined by three inputs:
Credit quality of the cover pool – Measured by a ‘collateral score’, with the
higher the quality of the cover pool, the lower the ‘collateral score’. To reflect a
highly rated issuer’s ongoing support for the cover pool, a collateral score may be
haircut to give the ‘collateral risk’ metric.
Refinancing of the cover pool – Assuming that natural portfolio amortisation will
be insufficient to meet covered obligations when due, the EL model assumes the
issuer must part-fund the cover pool following an anchor event, most likely at a
discount in a stressed environment. The assumed refinancing margin, proportion
of the cover pool exposed to refinancing risk, and the average life of refinancing
risk determines the programme’s ‘refinancing risk’.
Interest-rate and currency mismatches – Determining the amount of both risks
following a CB anchor event.
The TPI indicator reflects the probability of covered bond payments being made in a
timely fashion following a CB anchor event. Their calculation is derived from two
separate stages of analysis; first, a jurisdictional analysis considering the level of
systemic support and legal framework, followed by a programme-specific analysis
which looks at the contractual features of the shelf, including hedging arrangements.

The following is our synopsis of the methodology used by Standard & Poor’s to rate
covered bonds. For a complete overview of the Agency’s approach, please see
Covered Bond Ratings Framework: Methodology and Assumptions, published 30th
June 2015. In short, the rating’s framework involves four distinct phases:
Analysis of issuer specific factors to determine whether the covered bond rating
can be higher than that of the issuer itself;
Assessing the ratings starting point, based on various resolution regimes;
Determining the maximum covered bond rating from jurisdictional and covered
bond specific factors; and
Combining the above three steps, and adjusting for any additional factors such as
counterparty risk, country risk and sovereign default risk.

Under the Agency’s rating framework, there are four key stages to the ratings
process. Firstly, the Agency assesses whether the rating of the covered bonds may
exceed that of the issuer by considering legal & regulatory risks, alongside
operational & administrative risks.
The assessment of legal & regulatory risks considers the degree to which a covered
bond programme isolates the cover pool from the bankruptcy estate of the issuer. If
asset isolation is found to exist then a covered rating higher than the issuer’s own can
be assigned; if, however, the analysis concludes that there is a chance of a loss or

temporary disruption to programme cashflows following issuer insolvency, then a
higher rating than the issuer’s can only be assigned if additional structural mitigants
address the identified credit or liquidity risks.
Operational & Administrative risks focus on the key transaction parties, and whether
they are capable to manage a covered programme. This involves considering both the
ability of the issuer itself prior to any default event, and also the potential for a
successor manager.
Should the determination under Stage 1 be that the rating of the covered bond
programme should be higher than the issuer's credit rating, then Stage 2 determines
which reference rating should be used. In general, the Reference Rating Level
(‘RRL’) should be at least equal to the issuer's ICR, or supplemented by a number of
notches for programmes issued from regimes that are subject to bank resolution
regimes. In jurisdictions where the systemic importance of covered bonds is deemed
to be either ‘weak’ or ‘moderate’, one notch is added, in countries where it is viewed
as being ‘strong’ or ‘very strong’ the RRL may differ from the ICR by up to 3
notches.
Stage 3 of the Agency's approach conducts analysis on the level of Jurisdictional
Support, and considers the likelihood that a covered bond programme would benefit
from a government-sponsored initiative to maintain cashflows, rather than relying on
cover pool liquidation. This analysis takes into account the strength of the legal
framework, the systemic importance of covered bonds within a jurisdiction, and the
credit capacity of the sovereign. This Stage determines the maximum number of
notches above the RRL that a programme can be given.
Pool-specific factors also play a role in this stage of the ratings process, with an
analysis of the cover pool’s assets and the payment structure and cash flow
mechanics of the programme.
Finally, Stage 4 looks to capture considerations which are not directly related to the
covered bond issuer or the programme itself, but that would also affect the maximum
achievable rating. Most pertinently, these can be categorised as relating to
counterparty risks and country risks.

Legislative snapshot
We set out in Table 9 a snapshot of key covered bond attributes in Australia.
Table 9: Australian covered bond legislative overview
Attribute Commentary
Overview and key facts
Size The Australian covered bond market has around €52bn of distributed benchmark paper (>€500mm
equivalent) outstanding as of July 2019. Australian banks issued € of benchmark paper in FY 2017,
followed by benchmark supply of € in FY 2018. Meanwhile, in 2019 YTD, € of benchmark bonds
has been issued, of which €4bn is denominated in EUR.
Type of CB Mortgage covered bonds only.
Issuers The “big four”, joined by Suncorp Metway (although it has no benchmark covered bonds outstanding at
present), Macquarie, and more recently in 2017, Bank of Queensland.
Currencies USD-, EUR- and GBP-denominated bonds are the most common, although banks have issued AUD, NZD
and CHF bonds, mostly in non-benchmark size.
Framework
Legislative Framework The legal framework was introduced in October 2011 by Act 125, which amends the Banking Act of 1959 to
allow the issuance of covered bonds by Australian Authorised Deposit-taking Institutions (ADIs).
Types of covered bonds One, Mortgage-backed. Only Australian residential and commercial mortgages are allowed in the cover pool,
in addition to highly liquid substitute collateral and derivatives used for hedging purposes.
Structure of Issuer Direct issuance? Yes and no. The current construct is similar to that used in the Netherlands and in the UK, whereby a
securitisation technique is used to recreate a traditional covered bond structure using common and contract
law. The assets are purchased by a bankruptcy-remote vehicle (providing segregation for the cover pool
assets), the Guarantor, via an intercompany loan granted by the issuer and the Guarantor then provides a
guarantee on the issuer's covered bonds.
Comments (if any) The framework includes a "demand loan" feature, whereby the issuer can claim back any extra collateral
above the ACT. Issuance limits of maximum 8% encumbered assets in the cover pool as a proportion of the
ADI's total Australian assets.
Bankruptcy remoteness The assets are sold via a legal true sale to the Guarantor and are therefore segregated from the issuer.
Legal title to the assets remains with the issuer until the breach of a trigger.
Dual claim Yes
Bond format Typically fixed. Bonds can be extended by up to 12 months if the issuer fails to repay in full on original
maturity.
Supervision APRA
Cover pool
Eligible assets Mortgage Residential and commercial mortgages.
LTV caps For the calculation of the LTV-adjusted balance, only the first 80%/60% of residential/commercial loans is
taken into account.
Public Sector No public sector CB for the moment.
Non-performing collateral 0% weight in calculation of LTV-adjusted balance.
Substitution Assets Not allowed to exceed 15%.
Hedging Derivatives are allowed to hedge interest and exchange rate risk.
Valuation Individual asset market value. When conducting the Asset Coverage Test (ACT) LTV amounts in excess of
80% for residential loans and 60% for commercial loans are not considered.
Other comments (if any) n/a
Requirements
ALM matching Asset coverage The issuer is required to stress the cover pool when carrying out an ACT in order to ensure the cover pool is
enough to cover all covered
