An Overview of Collateralized Mortgage Obligations.

Before we get into the details of how our collateralized mortgage obligations prices are created, a quick review of collateralized mortgage obligations may be helpful.


Collateralized mortgage obligations (CMO) are a type of asset backed securities (ABS). They are made of a pool of mortgages bundled together and sold as an investment. CMOs receive cash flows as borrowers repay the mortgages that act as collateral on these securities. Then CMOs distribute the principal and interest payments to their investors based on predetermined rules and agreements.

Collateralized mortgage obligations consist of several tranches, or groups of mortgages, organized by their risk profiles. These tranches typically have different principal balances, interest rates, maturity dates, and the potential for repayment defaults. Collateralized mortgage obligations are sensitive to interest rate changes as well as to changes in economic conditions, such as foreclosure rates, refinance rates, and the rates at which properties are sold. Each tranche has a different maturity date and size and bonds with monthly coupons are issued against it. The coupon makes monthly principal and interest rate payments.

Investors in CMOs, sometimes referred to as Real Estate Mortgage Investment Conduits (REMICs), want to obtain access to mortgage cash flows without having to originate or purchase a set of mortgages.

CMOs were first offered in 1983 by Salomon Brothers and First Boston. These first CMOs were very complex and included many different mortgages. Investors seemed to focus on the income streams offered by CMOs rather than the health of the underlying mortgages themselves. As a result, many investors purchased CMOs full of subprime mortgages, adjustable-rate mortgages, mortgages held by borrowers whose income wasn’t verified during the application process, and other risky mortgages with high risks of default.


Collateralized debt obligations (CDOs) are similar to CMOs in that they consist of a group of loans bundled together and sold as an investment vehicle. However, CDOs don’t just contain mortgages. CDOs contain a range of loans such as car loans, credit cards, commercial loans, and even mortgages.

CMOs have been criticized as a contributing factor in the 2007-2008 financial crisis. At that time housing prices were rising which made mortgages look like safe investments. So investors bought CMOs, but market and economic conditions led to a rise in foreclosures and payment risks that financial models did not accurately predict. A consequence of the global financial crisis was increased regulations for CMOs and other mortgage-backed securities. For example, the SEC and FINRA introduced new regulations that mitigate the risk of these securities by creating margin requirements for covered agency transactions, including collateralized mortgage obligations.

Collateralized mortgage obligations evaluated prices updated daily and categorized by collateral, seniority, and type of tranche – DIH


Securities are grouped into categories based on collateral, seniority and type of tranche. A range of yields is determined for each category. For Re-REMIC, prepay and default vectors are calculated using models that reflect current market conditions (including views on housing and unemployment). These models also reflect the latest available remittance reports, which are used to generate loan-level performance expectations.

Using the model-supplied prepayment and default vectors, cashflows are generated for each of the tranches that comprise the Re-REMIC. Those cashflows are then aggregated and applied to the tranches that comprise the Re-REMIC structure.

Each individual tranche is reviewed to assign an adjustment factor to the baseline discount margin (DM) / yield. The adjustment factor is based on specific shelf and servicer names, bond Insurance (if applicable), structural / waterfall features, and underlying collateral quality.

Cashflows are discounted at the DM / yield according to the baseline yields and adjustments from above.
