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.

Empowering Our Community: AD&Co's Commitment to DEI and Social ImpactEventsAt Andrew Davidson & Co., Inc. (AD&Co), our dedication to Diversity, Equity, and Inclusion (DEI) has been a cornerstone of our values. We established our DEI Committee in 2020, following the tragic murder of George Floyd. Despite the evolving landscape, including the recent U.S. Supreme Court decision impacting affirmative action in higher education, we remain steadfast in our commitment to fostering an inclusive environment that strengthens both our employees and the company.
On August 15, we came together at our New York office for a meaningful community service project. Partnering with Volunteers of America® Greater New York's Operation Backpack®, our team assembled and distributed backpacks filled with essential school supplies for unhoused students across New York City. These backpacks, which serve elementary, middle, and high school students, included a personal touch: handwritten notes wishing each student a successful school year. We believe every child deserves access to the resources they need to thrive, and we're honored to contribute to easing their transition into a new school year.
AD&Co team assembled to fill backpacks with essential school supplies for unhoused and underprivileged children. Later that day, our team participated in the "Other Side of Wall St." walk led by Kamau Ware of Black Gotham Experience. The walk began with a naming ceremony introducing members of North America's first Free Black Settlement. As we explored the historical impact of these early settlers on New York City, we were struck by the absence of formal recognition for their contributions in the city's landmarks. Kamau's insightful stories and imagery brought to light the rich yet often overlooked layers of history, reminding us of the importance of acknowledging and celebrating all aspects of our past. As a Black woman in mortgage finance, I take pride in working for a firm like AD&Co, which not only supports but actively promotes the values of diversity, equity, and inclusion. Our ongoing efforts are a testament to our commitment to elevating our employees, enhancing our business, and advancing our industry.

Thoughts
The growing prevalence of artificial intelligence in the mortgage industry is shining a new light on the human biases that have pervaded the industry since its inception. AI is meant to bring fairness and objectivity to mortgage decisions, but it can’t perform fairly if it was built on an unfair system.

What does it mean to be mentally healthy? The answer is different for everyone. With all the extra anxiety that many of us have experienced since 2020, whether from uncertainty about COVID-19 or from other experiences that may be new to us, it’s important to acknowledge that it’s alright to not feel alright. Fortunately, there are numerous resources that are available locally, nationally, and in some cases through your workplace or benefits package. We might start by finding out what makes us feel better.
