Terms of Service

Use of this site is on the terms below. They exist to be clear about what published guidance is and what it is not.

Reuse of Content

Content on this site is its publisher's property. Short extracts with a credit and a link may be used freely; copying a page wholesale may not.

Currency of the Content

Every effort is made to keep this material correct, without any guarantee that it is. Regulations and market prices both change faster than published guidance does.

Changes

What appears on this page is the current agreement. Whatever appears here when a reader visits is the operative version.

Linked Resources

Where an outside site is linked, it is because it is relevant. The linked organization, its services and its accuracy are its own affair.

Not Advice for Your Job

The content is general information, not a professional opinion on any individual job. Where what is written here conflicts with what a qualified professional says about the actual job, the professional is right.

Liability

Responsibility for how the information is used rests with the reader. To the extent permitted by law, no liability arises from its use.
