Case Study: OneMain accelerates LDTI reserve calculations with Slope

OneMain cuts LDTI reserve run time by 85% with Slope

OneMain Solutions, a provider of insurance products, was facing significant challenges with their monthly LDTI reserve calculations. Their process was constrained by long run times on a traditional multi-core setup, taking over 13 hours and requiring manual intervention. This left Sally Smith's actuarial team with little time for analysis and created operational friction. To address this, they turned to Slope and its High Performance Mode (HPM) product.

By implementing Slope's HPM, OneMain fully automated their end-to-end LDTI process. The solution reduced their run time by 85%, allowing the complete reserve cycle to finish in just two hours instead of over a day. This efficiency reclaimed 1.5 days of analysis time each month, enabling the team to perform deeper attribution analyses and contribute more significantly to corporate forecasting. Slope delivered these performance improvements and greater organizational impact without increasing overall costs.
