All securitization models require some form of input to create the calculated outputs.  Some are on the asset/loans side, and some are on the bond side.  Currently, on the bonds side, our model supports structured parameters for fixed values in a model.

Model inputs are for inputs with changeable values.

Model input page:

A model input will be created through the model input page. Some of the fields are mandatory and others are optional.

  • Category - This is an optional field, allowing the user to define several model inputs under the same group in the dynamic expression.
  • Name - This is a mandatory field specifying the name of the model input.
  • ** The combination of the category + name of the model input must be unique.
  • Unit - Mandatory field. T-REX supports five types of units - Amount ($), percentage, Number, Boolean, and Date.
    • Amount ($), percentage, Number - When choosing those types, the default value is a float, entered manually by the user.
    • Boolean - In this type, the user can select a default value of TRUE/FALSE from a dropdown list.
    • Date - The user can select from a calendar dropdown or enter manually in a YYYY-MM-DD format.

  • Default value - Mandatory field. The user must define a default value that will be used when there is no periodical value, ensuring that the model input can never be blank.
  • Description - Optional field.

The user can use the model inputs via dynamic expression (see dynamic expression page).

For assigning periodical values for model input, see Actuals.
