Conditions of Use

Document date - September 2026

How current this is

Anything time-sensitive - figures, rules, and product details - should be checked against a current primary source, because a page written earlier can fall behind.

Updates and availability

Availability is not guaranteed. Content may be revised or withdrawn at the operator's discretion.

Sites run by others

Once a visitor follows an external link, the terms of that destination govern, not these.

Keeping this current

If any of this changes, the updated version supersedes the previous one as soon as it appears here.
