Audit and Advisory
Regulatory and financial reporting expertise
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.
Auditors’ experts
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. The experience and expertise that this team brings to the audit engagement is of specific relevance in the financial services sector but is also invaluable in any company where there are areas of financial uncertainty, like impairment of trade debtors, intercompany loans, share-based schemes, future employee benefit obligations, etc.
Specialist advisory services
We provide actuarial advisory services to Boards, Risk Committees, HR Committees and management in general, to manage, quantify and report various financial risks.
Given our experience as auditor’s experts, we have a thorough understanding of regulatory and compliance requirements which add significant value when providing advice to our clients on any aspect that will be subject to external audit. This “Auditor’s perspective” has further given the actuarial team exposure to a wide range of clients which, in turn, provides insight into best practices across the industry to be applied to the benefit of all our clients.
