Actuarial in action

A closer look at the kind of work and skill sets you’ll take on as an intern or actuary:

Pricing analysis

Build and test the models that determine how Liberty prices its products, directly impacting customers and the bottom line.

Project snapshot:

Large account pricing

The situation:

A more sophisticated pricing methodology was needed for auto fleet lines in Latin America.

The solution:

Leveraging Excel, VBA, SAS and SQL, an intern developed premium and pricing simulations, forecasted losses and exposures, and built a customizable tool replicable across other lines of business.

The impact:

A scalable pricing tool now available for use across multiple lines of business.

Project snapshot:

Pricing in the sharing economy

The situation:

The sharing economy was growing fast, but actuaries had little to no historical data to work with.

The solution:

Our interns built pricing templates using broader benchmark data to automatically price accounts in this emerging market.

The impact:

A repeatable pricing solution for a new and growing market segment, built from scratch.

Project snapshot:

Catastrophe reserving

The situation:

Liberty needed more accurate projections for catastrophic events to better inform reserve decisions.

The solution:

An Actuarial Development Program participant analyzed actual vs. expected severity of past events, identified key variables and built more accurate projection models.

The impact:

Reserve projections reported to senior leadership with greater accuracy than previous models.

Project snapshot:

Profitability analytics

The situation:

Data reporting and analytics processes across business lines needed modernization.

The solution:

Actuarial teams worked cross-functionally to help build a robust, scalable database uniting data sources from across the organization.

The impact:

Users across the business can now focus on driving value with actionable insights rather than managing data.

Project snapshot:

eCLIQ farm pricing

The situation:

Multiple farm insurance products were being offered across various platforms, creating complexity for customers and agents.

The solution:

Actuarial teams helped build a single underwriting platform for small businesses featuring one premier Farm insurance product, nationwide.

The impact:

A more user-friendly experience with flexible coverage options to better serve customers and agents.

I began my time at Liberty in the Actuarial Internship Program and learned so much in just three short months. The following summer, I interned at a life insurance company to experience something different, but it only solidified my desire to return to Liberty. My time in the Actuarial Development Program has been invaluable, and all my rotations have had a real business impact. My managers have always made my study time a priority, which has allowed me to progress toward the FCAS designation. But my favorite part about working at Liberty is the network of people that have helped me grow and develop.

I received thoughtful mentorship and found my footing in the actuarial field through my two summer internships with Liberty. Returning full-time to the Actuarial Development Program became a no-brainer and has been tremendous for my development thanks to the variety of valuable actuarial experiences I’ve gotten in rotations alongside extensive exam support. Beyond the actuarial growth opportunities, what kept me coming back to Liberty was the warm, welcoming culture and everyone I’ve had the pleasure of working with.

My actuarial journey with Liberty began during a summer internship in the Plano, TX office, where hands-on experience with actuarial work helped me fall in love with both the career and the company. My summer internships showed me how supportive and collaborative Liberty's culture truly is. After two incredible summers, I returned full-time through the Actuarial Development Program, where I now have the opportunity to explore different areas of the company through three rotations while feeling well-supported with study hours. The culture, community, and support are what make Liberty the right place for me.
