Case study

Canada EH

by Professor Ian H. Giddy
New York University

In an effort to broaden its investor base and to take advantage of the US asset-backed securities market, the Canada Mortgage and Housing Corporation has sold a pool of non-guaranteed mortgage loans to General Electric Capital Corporation. After discussions with the rating agencies, GE Capital has decided to securitize the pool by selling it to a Special Purpose Vehicle called Canada Enhanced Homes Trust 1. The Trust will finance the purchase by issuing two public bonds and placing an unrated tranche with a US hedge fund. The details of the pool and the asset-backed securities are shown below.

Sequential pay

Your task is to explain this deal to the CMHC mucky-mucks, and explain to them how the sequential-pay ('waterfall") structure can affect the cost of funding the pool. You should also indicate how prepayments can affect the average life and funding cost of the asset-backed securities. You can use and adapt the following spreadsheet:


  • Describe the legal structure of this securitization, using a diagram.
  • When will the A, B and C tranches be paid back? What is the weighted average life of these securities?
  • What is the estimated cost of funding the trust? (Use the Canadian Government bond curve and corporate bond spread tables tables at
  • How would your answers change if Canadians prepay their mortages at the rate of 2% per month? | | | | contact
