Audit and Advisory
The optimal solution to financial reporting and risk management in areas of uncertainty must go beyond merely doing the maths.
It must be accompanied by appropriate interpretation and the professional judgement that can be expected from actuaries to arrive at a fully informed solution. It further goes without saying that compliance with all audit and regulatory reporting requirements is not negotiable.
The combination of our actuarial skills and a deep understanding of the audit and regulatory environment, puts us in a perfect position to provide holistic solutions to our clients. A multi-disciplinary approach is followed where the actuarial team collaborates closely with the Auditors and other experts across SNG GT, with further access to global resources and expertise through the wider Grant Thornton International network of firms.

Quantitative analysis of uncertain future events gives a full understanding of the extent of estimation uncertainty and supports the Auditor to identify potential risks of material misstatement in financial statements.
