Welcome to The S-Curve
Now you will be able to receive the latest announcements, product updates, and our insights on the mortgage market in real time.
The name of the blog, the S-Curve, is a reflection of our logo and the central feature of our prepayment model. S-curves are seen in nature in many phenomenon, from population growth to prepayment and default models. Our first S-curve, in the early 1990s, used the arctangent function, then piece-wise linear functions, and evolved over time to be more complex and vary by FICO, loan size and LTV. This evolution encapsulates both the timeless nature of fundamental relationships and constant innovation to describe them better over time.
We hope you find the information useful and we look forward to your feedback.

Andrew Davidson & Co., Inc. (AD&Co) is pleased to announce the first release of the Auto LoanDynamics Model (AutoLDM).Products
The LDM v3.0.2 library adds AutoLDM to the v3.0.1 library.
Key benefits include:

- Extensive support of AutoLDM is available from experienced modelers.
- Model validation documentation is available.
AutoLDM is available via the LDM library and through the AutoKinetics application. For a full list of updates, read our LoanDynamics Model v3.0.2 Release Notes.
