Basic Process and Logic of Asset Securitization

The primary objectives of accelerating cash inflow are as follows: 1. To distribute borrowers’ default risk among investors, thereby achieving risk diversification. 2. To reinvest the recovered funds into other opportunities to generate additional profits. The second main thread involves the loan servicer, who essentially acts as an agent for the originator. The servicer’s main responsibilities include managing the loans and forwarding repayments made by borrowers to the Special Purpose Vehicle (SPV), which then distributes proceeds to investors. The above outlines the fundamental process of asset securitization. Now let us revisit the initial definition. Asset securitization refers to the process of transforming assets that lack liquidity but generate predictable and stable future cash flows—through a specific structural arrangement involving the separation and reallocation of risk and return elements within those assets—into securities that can be sold and traded in financial markets. “Assets lacking liquidity but generating predictable and stable future cash flows” constitutes the primary prerequisite for asset securitization. Let us examine several key terms closely: “lack of liquidity,” “predictable and stable,” and “future cash flows.” After lending funds at a fixed interest rate, what challenges does the originator face? First, its own working capital may become strained; second, the lent funds become unavailable for its own use. These lent funds remain inert on the originator’s balance sheet, unable to circulate—hence the term “lack of liquidity.” Is the repayment amount certain? Yes. Is the interest amount certain? Yes. Assuming no defaults occur, borrowers are contractually obligated to repay—this too is certain. Thus, the cash flow is “predictable and stable.” Is this money received now or later? Later. Since it will be received in the future, it qualifies as “future cash flows.” “Through a specific structural arrangement, separating and reallocating the risk and return elements embedded in the assets”—this represents one critical step in asset securitization. Securities issued by the SPV are structured into different tranches—for example: senior securities (rated AAA) with an annual interest rate of 4%, accounting for 80% of the total loan amount; mezzanine securities (rated BBB) with an annual interest rate of 6%, accounting for 15% of the total loan amount; and an equity tranche with an uncertain annual return, accounting for the remaining 5%.

What is asset securitization? How does the asset securitization process work?

The core feature of a dynamic asset pool is its ‘dynamic renewal during the term.’ Its ability to achieve such renewal hinges fundamentally on the revolving purchase mechanism. At issuance, a dynamic pool only specifies a set of ‘Eligible Asset Criteria,’ clearly defining the conditions assets must satisfy to qualify for inclusion—such as asset size, maturity, and credit rating—without identifying specific underlying assets. Dynamic pools are primarily designed to resolve maturity mismatches between short-term assets and long-term ABN (Asset-Backed Notes) products. For instance, consumer loans and credit card receivables—assets characterized by short maturities, high volume, and rapid turnover—would suffer from premature asset maturities and cash flow disruptions if placed in a static pool. The revolving purchase mechanism effectively addresses this challenge. Specifically, during the revolving purchase period of an ABN product, the manager uses recoveries generated by assets already in the pool (e.g., borrower loan repayments, debtor payments on receivables, rental income, etc.). After deducting amounts required to pay investors’ current-period returns and related fees, the remaining funds are continuously deployed to acquire new assets meeting the originally stipulated ‘Eligible Asset Criteria.’ Simultaneously, maturing, defaulted, or otherwise non-compliant assets are repurchased and removed, thereby enabling dynamic renewal of the asset pool. (4) Cash Flow Disbursement Projection Cash flows collected each period from the ABN’s asset pool—including both initial asset repayments and repayments from newly added assets in a dynamic pool—must be disbursed in the order of “first covering costs and expenses, then servicing returns and principal.” Disbursement Order Expenditure Category Specific Content Explanation 1 Relevant Statutory Taxes Includes statutory taxes arising from underlying asset operations and cash flow collections, such as VAT and surcharges, stamp duty, etc. Statutory mandatory expenditures take priority; taxes and management fees attributable to the trust property rank ahead of beneficiary distributions. 2 Mandatory Fees for Dedicated Account Management Includes custodian bank fees, supervision/funds custody bank supervision fees, and funds custody fees. Custodian/supervisory banks serve as core entities ensuring risk isolation of trust property and fund safety, overseeing the entire dedicated account fund flow and executing compliant disbursements; failure to pay these fees may cause the custodian bank to refuse payment instructions, directly jeopardizing product redemption—thus their priority ranking is immediately after statutory taxes. 3 Fixed Service Fees for Intermediaries Includes fixed management fees for the trustee/manager, ongoing service fees for the lead underwriter, annual audit fees for accounting firms, annual legal advisory fees for law firms, surveillance rating fees for rating agencies, and base fixed service fees for the asset servicer. These constitute essential, fixed expenditures necessary to maintain regulatory compliance, information disclosure, and underlying asset management throughout the product’s life—required in full regardless of asset pool performance; failure to pay triggers disclosure violations and cessation of intermediary services, potentially leading to product default. 4 Current-Period Interest Payable on Senior Securities Current-period interest payable on senior securities: paid sequentially according to increasing risk level across senior tranches (e.g., Senior Tranche A → Senior Tranche B → Senior Tranche C, etc.) Senior interest represents a rigid, current-period contractual obligation; any delay directly triggers default and must be fully safeguarded at all stages. 4 Revolving Purchase Fund Disbursement (during revolving purchase period) 1. During the revolving purchase period: after paying interest, remaining funds in the dedicated account are prioritized in full for purchasing new eligible assets; if no qualifying assets are available for purchase in the current period, surplus funds are retained as excess reserves or carried forward to the next period for revolving purchase. 2. During amortization or default periods: revolving purchases formally cease; no such disbursement applies. During the revolving period, no principal repayment schedule is typically established; only senior interest is paid as agreed. After satisfying current-period interest obligations, all remaining underlying asset recoveries in the dedicated account are prioritized for purchasing new eligible assets conforming to criteria specified in the offering documents.
