The System of National Accounts is an international system so that countries can operate and compare their financial statistics in comparable terms.
There are revisions to the system to ensure the system is properly recording certain revenues and expenses, and likewise economic activity, consistently across countries.
In the most recent revisions, there were some differences, as the member asked for in very simple terms, just in the treatment of cash versus accrual items for certain objects in the System of National Accounts. Where we used to account for them on a cash basis, with this System of National Accounts, it's gradually moving towards more of an accrual-based system, for things such as capital expenses and pension expenses.
