FOR PRODUCTION DURING FINANCIAL YEAR STARTING ON, OR AFTER, 1st JANUARY 2023


International Branches

Please note that for the larger auditing firms listed (such as KPMG or PwC), each international branch needs to be approved as an auditor separately. Each branch not listed as an audit (“Non-Listed Branch”) will need to submit a separate application form, or alternatively, the Non-Listed Branch will need to have all their audits approved by a listed branch (listed branch refers to a branch approved as an auditor). However, we request that you initially approach the listed contact under each institution so that they may assist their colleagues directly.

Additional Assurance Providers

If you have experience working with an auditing company, please pass on their contact details to anne.dennison@lppm.com so that we can approach them to become part of the Approved Assurance Providers List.
