Reference numbers explained

The Guidance notes have been arranged into categories by theme. Each note has been assigned a unique reference number (e.g. UKLA/TN/101.1 or UKLA/PN/901.1).

The ‘TN’ indicates that it is a Technical note and the ‘PN’ indicates that it is a Procedural note.

The first three digits, ‘101’ and ‘901’ refer to the topic or title of the note.

The final digit ‘1’ indicates that it is the first version of this note to be published. If changes are made to the note in the future, the final digit will be changed to ‘2’, ‘3’ etc to reflect the most recent version.
