(The following statement was released by the rating agency) Fitch Ratings-Sydney-06 October 2020: Fitch Ratings has affirmed two classes of notes from Medallion Trust Series 2008-1R. The transaction consists of notes backed by Australian residential mortgages originated by Commonwealth Bank of Australia (CBA, A+/Negative/F1). The notes were issued by BNY Trust Company of Australia Limited in its capacity as trustee of Medallion Trust Series 2008-1R. The social and market disruption caused by the coronavirus pandemic and the related containment measures did not negatively affect the ratings because there was sufficient credit enhancement to provide an offset under Fitch's base-case scenario as well as adequate liquidity to support the ratings. The Stable Outlook is based on the notes' liquidity support and ability to withstand sensitivity to higher defaults stemming from the pandemic. Medallion Trust Series 2008-1R ----Class A AU3FN0005617; Long Term Rating; Affirmed; AAAsf ----Class B ; Long Term Rating; Affirmed; AAsf KEY RATING DRIVERS Pandemic-Related Economic Shock: Fitch has made assumptions about the spread of the coronavirus and the economic impact of containment measures. In a base-case (most likely) scenario, Fitch assumes a global recession in 1H20, driven by sharp economic contractions in major economies, with a rapid spike in unemployment, will be followed by a recovery that begins in 3Q20 as the health crisis subsides. In a downside (sensitivity) scenario in the Rating Sensitivities section below, Fitch considers a more severe and prolonged period of stress, with recovery to pre-crisis GDP levels delayed until around the middle of the decade. Pandemic-Related Impact: Measures to limit the spread of the coronavirus are affecting Australia's economy, with many businesses continuing to experience a decline in income. We expect these measures to affect mortgage performance, but there should be no rating impact on the rated notes, as the ratings can absorb Fitch's base-case scenario of the pandemic. In addition, the class A notes will have subordination that is at least 1.7x greater than the 'AAAsf' portfolio loss. Commentary describing Fitch's credit views and analytical approach as a consequence of the coronavirus is available in the following reports: - "Global Economic Outlook - September 2020 ", published on 7 September 2020, available at https://www.fitchratings.com/site/re/10135033; - "Fitch Ratings Coronavirus Scenarios: Baseline and Downside Cases - Update", published on 8 September 2020, available athttps://www.fitchratings.com/site/re/10135320; and - "Global SF Rating Assumptions Updated to Reflect Coronavirus Risk", published on 3 April 2020, available at www.fitchratings.com/site/pr/10117224. Analytical notes relevant for Australian and New Zealand RMBS transactions are discussed in the following commentary: - "Fitch Ratings' Approach to Addressing Coronavirus-Related Risks for Australian, NZ RMBS", published on 5 May 2020, available at www.fitchratings.com/site/pr/10120792. - "Fitch Ratings Updates Australia, NZ RMBS Criteria Assumptions on Coronavirus Effects", published on 29 July 2020, available at www.fitchratings.com/site/pr/10130287. Liquidity Risk from Payment Holidays: We have reviewed the ability of the transaction to survive a significant proportion of borrowers taking a payment holiday. The transaction benefit from a liquidity facility sized at AUD1.35 billion that is sufficient to cover six months of required payments at the current bank-bill spot rate, should there be no principal or interest collections, which is well above the 9.3% of mortgages on payment holiday arrangements at the end of July 2020. The transaction can also use any principal payments received to pay interest if not all borrowers take up payment holidays. Operational Risk: CBA has a strong franchise in Australia and New Zealand, particularly in retail banking, leading to high market share that allows the bank to operate a simple business model with stable earnings. CBA, as a regulated bank, is obliged to comply with minimum lending standards set by the Australian Prudential (LON:PRU) Regulation Authority; these are consistent with market standards. Fitch undertook an onsite operational review and found the originator's and servicer's operations were in line with market standards for conforming lenders and that there were no material changes that may affect CBA's ongoing ability to undertake administration and collection activities. The collection timelines, policies and procedures are in line with those of other conforming lenders in Australia. We do not expect the servicer's operations to be disrupted by the pandemic, as staff are able to work remotely and have access to the office. Asset Analysis: The transaction allows for the addition of new receivables during the substitution period, ending May 2030, in accordance with eligibility criteria and portfolio parameters. Structural features and performance-based triggers have been included to restrict the ability to add new receivables in certain circumstances. At end-July 2020, 30+ days and 90+ days arrears, including loans in hardship, were 0.47% and 0.21%, respectively, below Fitch's 2Q20 Dinkum RMBS Index arrears of 1.16% and 0.61%, respectively. Loans in hardship not related to the pandemic were included in the arrears reporting. Medallion Trust Series 2008-1R had low levels of losses since closing. At end-July 2020, the transaction recorded a loss of AUD255,017 that, after exhausting available excess spread, resulted in a charge-off on the class C notes. Liability Analysis: The class A and B notes have sufficient credit enhancement of 10.9% and 4.5%, respectively, provided by their respective subordinated notes. Structural features include a liquidity facility sized at AUD1.35 billion, with a floor of AUD135 million. While not all rated notes are at the highest possible rating because the transaction features a revolving period, the cash flow model was not updated for surveillance purposes during the revolving period given the following conditions were met: cash flow distributions have been within expectations since the last cash flow model analysis and there have been no material changes to cash flow assumptions since the last cash flow model analysis. At end-July 2020, there was a charge-off that reduced the stated balance of the class C notes by AUD255,017. The charge-off had a minor impact on the credit enhancement of the rated notes, but no material effect on the ratings, as the rated notes have sufficient enhancement to support their ratings. Macroeconomic Factors: Fitch expects mortgage performance to deteriorate in the near term, but to continue to support the Stable Outlook for the notes. Fitch forecasts Australia's GDP will contract by 3.6% in 2020, with the unemployment rate at 7.1%. This will be partially offset by a low cash rate of 0.25% and the application of both central bank and government stimulus measures. Fitch expects GDP growth to bounce back to 3.9% in 2021 and the unemployment rate to fall to 6.7%. RATING SENSITIVITIES Factors that could, individually or collectively, lead to positive rating action/upgrade: The class A notes are at 'AAAsf', which is the highest level on Fitch's scale. The ratings cannot be upgraded. The class B notes may be upgraded if there is sufficient increase in credit enhancement due to restructuring or as the transaction amortises to fully compensate for credit losses and cash flow stresses commensurate with higher rating scenarios, all else being equal. Factors that could, individually or collectively, lead to negative rating action/downgrade: A longer pandemic than Fitch expects that leads to deterioration in macroeconomic fundamentals and consumers' financial position in Australia beyond Fitch's baseline scenario. Available credit enhancement cannot compensate for higher credit losses and cash flow stresses, all else being equal. Fitch conducted sensitivity analysis by increasing gross default levels and decreasing recovery rates over the life of the transactions. Notes class: A / B Current Rating: AAAsf / AAsf Expected impact on note ratings of increased defaults: Increase defaults by 15%: AAAsf / A+sf Increase defaults by 30%: AAAsf / Asf Expected impact on note ratings of decreased recoveries: Reduce recoveries by 15%: AAAsf / A+sf Reduce recoveries by 30%: AAAsf / A+sf Expected impact on note ratings of multiple factors: Increase defaults by 15% and reduce recoveries by 15%: AAAsf / Asf Increase defaults by 30% and reduce recoveries by 30%: AAAsf / BBBsf Coronavirus Downside Scenario Sensitivity Fitch's coronavirus downside scenario assumes that a re-emergence of infections in the major economies prolongs the health crisis and confidence shock, prompting extensions or renewals of lockdown measures and preventing a recovery in financial markets. Under Fitch's downside scenario, the class A notes would not be downgraded, while the class B notes rating would be vulnerable to a three-notch downgrade. Best/Worst Case Rating Scenario International scale credit ratings of Structured Finance transactions have a best-case rating upgrade scenario (defined as the 99th percentile of rating transitions, measured in a positive direction) of seven notches over a three-year rating horizon; and a worst-case rating downgrade scenario (defined as the 99th percentile of rating transitions, measured in a negative direction) of seven notches over three years. The complete span of best- and worst-case scenario credit ratings for all rating categories ranges from 'AAAsf' to 'Dsf'. Best- and worst-case scenario credit ratings are based on historical performance.

USE OF THIRD PARTY DUE DILIGENCE PURSUANT TO SEC RULE 17G -10 Form ABS Due Diligence-15E was not provided to, or reviewed by, Fitch in relation to this rating action. DATA ADEQUACY Fitch has checked the consistency and plausibility of the information it has received about the performance of the asset pool and the transaction. There were no findings that were material to this analysis. Fitch has not reviewed the results of any third-party assessment of the asset portfolio as part of its ongoing monitoring. Prior to the transaction closing, Fitch reviewed the results of a third-party assessment conducted on the asset portfolio information and concluded that there were no findings that affected the rating analysis. As part of its ongoing monitoring, Fitch reviewed a small targeted sample of CBA's origination files and found the information contained in the reviewed files to be adequately consistent with the originator's policies and practices and the other information provided to the agency about the asset portfolio. In our previous loan file review on CBA, there were discrepancies noted in the security valuations provided in the loan file data compared with the source data from CBA. These discrepancies in the valuation data have now been resolved. Overall, Fitch's assessment of the asset pool information relied upon for the agency's rating analysis according to its applicable rating methodologies indicates that it is adequately reliable.

In issuing and maintaining its ratings and in making other reports (including forecast information), Fitch relies on factual information it receives from issuers and underwriters and from other sources Fitch believes to be credible. Fitch conducts a reasonable investigation of the factual information relied upon by it in accordance with its ratings methodology, and obtains reasonable verification of that information from independent sources, to the extent such sources are available for a given security or in a given jurisdiction. The manner of Fitch's factual investigation and the scope of the third-party verification it obtains will vary depending on the nature of the rated security and its issuer, the requirements and practices in the jurisdiction in which the rated security is offered and sold and/or the issuer is located, the availability and nature of relevant public information, access to the management of the issuer and its advisers, the availability of pre-existing third-party verifications such as audit reports, agreed-upon procedures letters, appraisals, actuarial reports, engineering reports, legal opinions and other reports provided by third parties, the availability of independent and competent third- party verification sources with respect to the particular security or in the particular jurisdiction of the issuer, and a variety of other factors. Users of Fitch's ratings and reports should understand that neither an enhanced factual investigation nor any third-party verification can ensure that all of the information Fitch relies on in connection with a rating or a report will be accurate and complete. Ultimately, the issuer and its advisers are responsible for the accuracy of the information they provide to Fitch and to the market in offering documents and other reports. In issuing its ratings and its reports, Fitch must rely on the work of experts, including independent auditors with respect to financial statements and attorneys with respect to legal and tax matters. Further, ratings and forecasts of financial and other information are inherently forward-looking and embody assumptions and predictions about future events that by their nature cannot be verified as facts. As a result, despite any verification of current facts, ratings and forecasts can be affected by future events or conditions that were not anticipated at the time a rating or forecast was issued or affirmed. The information in this report is provided "as is" without any representation or warranty of any kind, and Fitch does not represent or warrant that the report or any of its contents will meet any of the requirements of a recipient of the report. A Fitch rating is an opinion as to the creditworthiness of a security. This opinion and reports made by Fitch are based on established criteria and methodologies that Fitch is continuously evaluating and updating. Therefore, ratings and reports are the collective work product of Fitch and no individual, or group of individuals, is solely responsible for a rating or a report. The rating does not address the risk of loss due to risks other than credit risk, unless such risk is specifically mentioned. Fitch is not engaged in the offer or sale of any security. All Fitch reports have shared authorship. Individuals identified in a Fitch report were involved in, but are not solely responsible for, the opinions stated therein. The individuals are named for contact purposes only. A report providing a Fitch rating is neither a prospectus nor a substitute for the information assembled, verified and presented to investors by the issuer and its agents in connection with the sale of the securities. Ratings may be changed or withdrawn at any time for any reason in the sole discretion of Fitch. Fitch does not provide investment advice of any sort. Ratings are not a recommendation to buy, sell, or hold any security. Ratings do not comment on the adequacy of market price, the suitability of any security for a particular investor, or the tax-exempt nature or taxability of payments made in respect to any security. Fitch receives fees from issuers, insurers, guarantors, other obligors, and underwriters for rating securities. Such fees generally vary from US$1,000 to US$750,000 (or the applicable currency equivalent) per issue. In certain cases, Fitch will rate all or a number of issues issued by a particular issuer, or insured or guaranteed by a particular insurer or guarantor, for a single annual fee. Such fees are expected to vary from US$10,000 to US$1,500,000 (or the applicable currency equivalent). The assignment, publication, or dissemination of a rating by Fitch shall not constitute a consent by Fitch to use its name as an expert in connection with any registration statement filed under the United States securities laws, the Financial Services and Markets Act of 2000 of the United Kingdom, or the securities laws of any particular jurisdiction.
