Case Study: a commercial P&C insurer strengthens internal audit and supports growth with Grant Thornton LLP

Insurer uncovers $1 million+ deductible with Grant Thornton LLP

The customer, a commercial property and casualty insurer, faced an immature internal audit function that could not support its strategic expansion into new markets. To address this challenge, the insurer partnered with vendor Grant Thornton LLP to enhance its internal audit framework and capabilities.

Grant Thornton provided a co-sourced solution, delivering subject matter experts to execute a new risk-based audit plan. This partnership helped the insurer build a robust internal audit foundation for its growth. A significant measurable result was the discovery of over $1 million in a reimbursable deductible owed to the client. Grant Thornton also provided recommendations to optimize the insurer's use of its existing Guidewire platform, reducing manual work and potential errors.
