Financial Intermediation
Traditionally, banks
1) originate a loan;

3) service the loan (collect payments and take legal action if payments were not made; and
4) obtain funds from the public with which to finance their assets.

Asset Securitization
Recently, banks
1) originate a loan;
2) sell the loan to an investment banking firm that creates a security backed by the pool of loans;
3) the investment bankers obtain credit risk insurance for the pool of loans from an insurance company;
4) the investment banker can sell the right to serve the loan to another bank or a company specializing in servicing loans; and
5) the investment banking firm can sell the securities to individual and institutional investors.

Defining Asset Securitization
• What is Securitization?- the sale of securities backed by the cash flows from a pool of financial assets, such as loans or le
ases
• Three basic requirements for any securitization:- a pool of self-liquidating assets that will serve as the source of payments on the asset-backed securities.
- the payment performance of the assets (including the likelihood of delays and defaults) must be susceptible to evaluation, and
- the cash flow from the assets and the payments made on the securities must be isolated from the risks of a bankruptcy or insolvency of the originator.
• Securitization involves the sale of assets which generate a cash flow such as residential mortgage loans, commercial mortgage loans, credit card receivables, motor vehicle receivables owed by dealers or retail consumers, equipment and vehicle lease receivables, installment sale contracts, franchise loans, insurance loans, student loans and high yield bonds. The money raised by the entity is borrowed on the security of the assets it has purchased and the debt is repaid from the cash flow generated by those assets.

定義• 證券化 (securitization)-
簡言之 , 凡是以發行證券直接在資本市場上籌措資金的叫做證券化 . 或言 , 利用發行證券的形式到資本市場籌措資金 , 而投資人對標的資產的未來現金流量具有求償權 .
• 不動產證券化 (Real Estate Securitization)
利用發行證券的形式來轉化不動產單一固定性的投資為流動性高的證券投資 . 使得不動產的投資由直接的物權關係轉為間接的債權關係 . 資金得由證券的形式由資本市場注入不動產市場 .
為何有不動產證券化• The bringing together of sources and uses of capital is the
core to the finance function. In a world of costless transactions, suppliers of capital would be able to identify and meet users in need of debt and equity to carry out their investment objectives or development plans.
• However, the world of real estate finance and investment is far different from the world described above.
• Financial instruments and other devices have been developed by financial intermediaries to facilitate the necessary transactions.

賃費 , 再轉給信託銀行5. 信託銀行按持分分錢給投資者6. 最後 , 信託銀行可出售土地建築物 , 再將錢分給投資者• 組合型不動產證券化
美日兩國不動產證券化運作之比較
1) REITs: 先募集資金再找不動產投資標的。 信託型不動產證券化 : 先有不動產﹐將所有權細分後﹐
再以證券型態賣給投資者。2) REITs: 以 REIT 方式發行之憑證可在公開市場轉售﹐流
動性極佳。 信託型不動產證券化 : 有價證券之定義中不含不動產信
託的有價證券﹐故而無法在公開市場轉售﹐流動性差
