VIS Credit Rating Company Limited vis.com.pk 3 VIS Credit Rating Company Limited STRUCTURED FINANCE MAY 2025 INTRODUCTION Structured finance instruments are complex financial products designed to manage and transfer risk, typically through the pooling and repackaging of cash-flow-generating assets. These instruments, such as Collateralized Debt Obligations (CDOs), Mortgage-Backed Securities (MBS), Asset-Backed Securities (ABS), and Collateralized Loan Obligations (CLOs), help companies and financial institutions optimize capital structures and manage credit risk. Securitization is a key process within structured finance, where corporations in need of funds transfers its specific asset or pool of assets, usually relatively illiquid ones,to a special purpose vehicle (SPV), which then issues debt instruments secured by the cash flows from or the value of those assets, in order to raise funds. The securitization process entails rearrangement (structuring) by the packager of certain assets in the form of securities, supported by a well-defined and isolated cash flow stream, so that the assets become more salable to the investors. The cash flow stream may be related either to assets that already exist at the time of issuance or to the assets the originator is expected to generate during the term of securities. The former is an asset-backed securitization (ABS), and the latter is future flow securitization (FFS). The Asset-Backed Securitization Regulations, 2022, issued by the Securities and Exchange Commission of Pakistan (SECP) under the Companies Act, 2017, and the Securities Act, 2015, establish a and comprehensive regulatory framework for raising funds through securitization in Pakistan. These regulations are applicable to every SPV that issues debt securities, including redeemable capital, debentures, or sukuk, backed by a pool of assets. Additionally, SPVs owned by the federal or provincial government have the option to voluntarily adopt this framework. SUMMARY OF CRITERIA CHANGES The rating methodology itself remains essentially unchanged; however, the document has been reorganized and updated to enhance clarity and improve formatting. OVERVIEW OF RATING FRAMEWORK The rating framework for securitization transactions aims to assess credit risk, guiding investors on the likelihood of timely debt repayment. VIS evaluates transaction structure, asset quality, cashflows, legal frameworks, servicer Major Asset Backed Products Mortgages: Fixed contractual nature; consistent documentation and approval standards. Auto Loans: Fixed rate; level payment instruments; standardized documentation and processes; strong underlying asset value. Trade Receivables: Non-yielding, sold at discount that imputes a yield that also adjusts credit enhancement. Originators are generally manufacturing and service companies. Lease Receivables: Assets with predictable cashflows. Future Flow Securities: Usually backed by future export receivables, international telephone call settlements, international credit card settlements, airline ticket and oil & gas receivables.

Structure of Securitization A typical securitization structure consists of an originator whose business gives rise to the receivables that collateralize an asset-backed structure. The collection of receivables is done by the servicer, who also takes appropriate enforcement actions when necessary to pursue the payment. The originator's familiarity with the receivables and the obligors makes it the preferred party to service the receivables However, in the case of the originator having weak credit standing, it is likely that some third party will be required to fill in the role of a servicer. The receivables are sold to a bankruptcy-remote legal entity, the SPV, that is established for the specific purpose of facilitating the financing with a very limited scope of operations so that its own business and financial risks are limited. A trustee is also featured in the transaction to safeguard the investors' interests and the supporting facilities and the entitlements of beneficiaries for their payments. Professional advisors such as arrangers, legal counsel, and external auditors also add support to the transaction while a rating agency assesses the risk in the transaction, which ultimately determines the cost of funds for the originator. The resultant securities issued by the SPV are bought by investors. Finally, regulators also play a vital role in ensuring that securitization does not undermine prudential supervision, especially in respect of exposure limits. A number of incentives offered by securitization renders it attractive compared to other methods of funding. With the right assets, credit enhancement and securitization terms, the securities issued may have a better credit rating than that of the originator. A better credit rating usually leads to lower financial cost on the securities issued, a broader investorbase and greater investor receptivity to longer maturities. It also provides an opportunity to an originator with a below investment-grade rating to issue investment-grade securities. In case of high yielding portfolios/pools, there is profit on sale, as the IRR on the pool is higher than coupon on ABS. Hence there is a boost to the bottom-line and EPS in the year of securitization. Securitization may also help release funds locked up in lower yielding assets for redeployment at higher rates. Moreover, securitization generates cash without any addition to the originator's borrowings and without impacting the debt-leverage of the originating company. Banks and DFIs who are fully exposed to some corporates or groups can do more business with them without violating regulations by securitizing their higher rates. Moreover,

Banks and DFIs who are fully exposed to some corporates or groups can do more business with them without violating regulations by securitizing their existing exposure. RATING METHODOLOGY The rating methodology involves analyzing transaction structure to mitigate risks, assessing asset quality, evaluating cashflow adequacy, conducting legal reviews for bankruptcy protection, examining servicer reliability, and considering credit enhancements to ensure investor security. A. TRANSACTION STRUCTURE A number of potential risks must be addressed and covered by the transaction structure. These include interest rate risk, prepayment and reinvestment risks and currency risk. For instance, in the FFS transaction of Pakistan Telecommunication Company Limited (PTCL), which was the first Asian telephone company to securitize the future tele￾com receivables worth US$ 250m in 1997, the transaction was rated several notches above Pakistan's sovereign rating as the structure of the transaction provided protection from Pakistan's sovereign foreign exchange and convertibility risk. It should be kept in mind that unlike ABS, where a higher rating can be achieved through the isolation of quality assets from the credit of the originator, the ratings of FFS transactions are invariably of FFS transactions are invariably linked to the credit quality of the originator. Hence, VIS will only consider notching the FFS transaction rating above the originator's entity rating, if the receivables are likely to be generated even after the originating company has defaulted on its senior unsecured debt and a legal structure is in place to ensure the same. This also implies the appointment of a competent backup servicer, which has been discussed at length later in this section. B. ASSET ANALYSIS It is imperative to gauge the credit quality of assets being securitized and originator's ability to generate and manage assets. This entails conducting due diligence meetings to evaluate the originator's underwriting procedures and discuss the historical performance data of the assets. Asset analysis involves reviewing and assessing the assets based on past performance - typically five years of default and delinquency data - and an understanding of how and why this performance may significantly change going forward. Future expected performance would be a function of a number of factors viz. default history and future generic changes affecting the assets. These factors establish the foundation to assess loan seasoning, concentration risk, and prepayments. Further, the performance and nature of general market, the originator's competitors and position in the market as well as the industry-specific risks are also analyzed closely. C. CASH FLOW ANALYSIS This involves analysis of the cashflow model which should reflect the fund flows as depicted in the transaction including the stress assumptions derived in the asset analysis phase. The model should demonstrate that the cash flowing out to pay the investors is always adequate to ensure that they are paid in full on a timely basis. The cashflow must also reflect the priority of payments in the transaction documents.

VIS Credit Rating Company Limited vis.com.pk 6 VIS Credit Rating Company Limited STRUCTURED FINANCE MAY 2025 D. LEGAL ISSUES & DOCUMENTATION ANALYSIS A securitization transaction is premised on the ability to legally isolate the assets transferred by the originator to the SPV from bankruptcy risks associated with the entities involved. This essentially requires a true sale to be achieved in the transfer of assets from the originator to the SPV so that it has a perfected, first priority ownership in the assets and the originator does not retain any residual beneficial interest in the underlying assets. As part of the rating methodology, true sale to a bankruptcy-remote SPV is one of the most crucial aspects and needs to be verified, as it serves as a key risk mitigant for investors in the transaction. Therefore, legal counsel will be required to provide an opinion confirming that all necessary actions to perfect the SPV's rights in the assets have been completed. This minimizes the risk of re￾characterization of sale by the court of law as a secured loan rather than a true sale in the event of the originator's bankruptcy. Since these opinions are simply views of legal counsel, it is important that a reputable and competent firm having knowledge and experience in such matters of law provides them. The analysis of true sale mainly focuses on whether the originator has transferred the economic benefits and risks to the SPV. This entails fulfillment of a number of conditions including a contract of asset assignment specifying the transaction to be construed as a sale of assets between the parties concerned, the assigned assets to be specified, the fair value of assigned assets and payments for them to be matched, and the originator having no repurchase obligation and has no recourse to the assigned assets. Further, careful review of the documentation regarding the transaction provided by the issuer's legal counsel is also required. Notices and acknowledgments also aid in providing legal opinions with regards to true sale. In order to address payment diversion risk, which may result in the obligors directing payment of SPV's receivables to the originator, the originator instructs the obligors of the transferred receivables to make all payments to a collection account under the control of a trustee. The obligors acknowledge the receipt of these notices by countersigning them. In some countries, certain laws provide for perfection of assets sold to SPV; for instance, in Japan, under the law regarding Regulation of Business Concerning Specified Claims, public notice of the registration constitutes the validity of perfection. Besides being unaffected by the originator's bankruptcy, it is imperative that the SPV be remote from its own bankruptcy. This is accomplished by restricting the scope of operations of the SPV in order to secure its independence. SBP and SECP have also laid down certain criteria to secure the independence of SPV. This includes clauses such as originator restricted from holding any equity stake in the SPV or having any of its directors, officers or employees on the board of SPV and in case where originator is also the administrator, the administration services to be provided on an arms length basis and on market terms and conditions. E. SERVICER ISSUES The structure of an ABS transaction will often involve the appointment or identification of a competent back-up servicer who replaces the existing servicer in the event of termination or breach by the servicer of the servicing agreement entered into with the trustee. In case of FFS, the trans-action documents will usually provide for the right to appoint an independent back-up servicer if these events occur, but the back-up servicer is not necessarily identified at the time the transaction is concluded.

VIS Credit Rating Company Limited vis.com.pk 7 VIS Credit Rating Company Limited STRUCTURED FINANCE MAY 2025 Further, if the originator is the servicer, its role should be clearly defined as a collection agent providing services to the SPV on an arm's length basis and the originator must be paid a reasonable fee for its collection services. It is also vital to establish measures aimed at protecting and preventing the commingling of receivable collections by isolating the SPVs receivable collections from other funds held by originator and directing them to the SPVs trustee. F. CREDIT ENHANCEMENTS In order to mitigate the potential loss associated with the credit risk of the assets and the disruption of payments on the securities, securitized transactions have several levels of credit enhancement both internal and external. Some forms of internal credit enhancement are: Over-collateralization This is achieved by the SPV owning assets of a greater value than the funds it raises from the investors. The accounting treatment of this difference will be important for the originator. However, it should be ensured that overcollateralization does not go beyond a certain limit as this undermines the purpose of true sale. Excess spread account Such accounts are feasible where the income received on the receivable portfolio is significantly higher than the total running costs of the than the total running costs of the funds borrowed to finance them. In its simplest form, a spread account traps net excess spread within the SPV to an amount sufficient to satisfy the credit quality requirements. Cash collateral or reserve account This is required to safeguard against short-term disruptions in the cashflow. Cash collateralization works in much the same way as over-collateralization except that its quality is self evidently higher and more tangible than the quality of receivables yet to be turned into cash. Cash collateral or reserve accounts maybe drawn at the onset of the transaction and invested with maturity that matches the periodicity of payments to the investors. Credit tranching Also known as 'Subordination', in credit tranching structure the cashflows available to the investors are allocated in a predetermined order of priority. The junior certificate holders will absorb losses before more senior tranches. Further, the senior certificate holders will rank in priority to the more junior notes for coupon and principal payments as well as in the event of the security being enforced. Performance Guarantee This entails a range of indemnities provided by the originator to the SPV such as assuring the SPV that the assets were written within regulatory parameters correctly or, in case of consumer receivables, warranting the replacement of the assets which have been incorrectly sold to the SPV and which do not conform to the selection criteria laid down at the outset of the transaction. Performance deterioration triggers Also called Triggered Amortization', they provide protection to the investors via the early detection of deteriorating credit quality of the receivables in case of ABS and the originator in case of FFS. Such triggers are a regular feature of transactions backed by rapidly revolving assets such as credit cards and personal loans. These performance triggers may

VIS Credit Rating Company Limited vis.com.pk 8 VIS Credit Rating Company Limited STRUCTURED FINANCE MAY 2025 result in the trustee trapping additional funds, accelerating amortization of debt and preventing additional asset purchases in case of a revolving structure. Covenants In most FFS transactions, there are general corporate covenants that constrain the company's ability to take on additional debt, to pay dividends and maintain debt leverage consistent with the rating assigned. External credit enhancement may be in the form of a bank letter of credit or a financial guarantee from a financial institution andgenerally provides assurances oftimely payment on securities. The guarantee may either cover part of the issue (Partial Guarantee) or the full amount of the issue (Wrap Guarantee). The institution providing this enhancement must be an entity with a rating at least as high as the desired transaction rating. However, according to the ABS guidelines issued by the SBP, banks and DFIs are not allowed to extend any fund or non-fund based facility to the SPV except where the facility is secured against an internationally 'A' rated bank guarantee or against cash or near cash collateral. This limits the role of these institutions in providing credit enhancement to the SPV. Another mode of external credit enhancement is a put or purchase option, which entails having the originator or a third party agree to purchase from the SPV what is left in the asset portfolio after it drops to a size (normally 10% of the original outstanding amount) which is considered too small to be economically administrable when held by investors.
