A unique, randomly generated number assigned to every visitor. It effectively lets a site know that it's communicating with the same browser each time a visitor does anything. No personal information is stored and it is destroyed when the browser is closed. When you revisit the site, your browser will be issued with a new one.
Google Analytics is used on almost every page of our main site. The statistics gathered help us to understand how our site is used. Google Analytics uses four cookies, none of which provide us with any personal information:
Each time someone visits a page they are provided with a unique ID via the __utma cookie. This is used to log the number of unique visits to a site.
__utmb & __utmc
Only the first of these two cookies is used to establish a session; the other one is now redundant but is still written. This is used to indicate how long a user spends on any pages visited.
This shows how visitors were referred to a site, e.g. via a search engine, directly, a link from another website, etc. It also shows which pages were visited once there.
LivePerson is used on the pages of several departments and services. This offers live chat functionality and requires several cookies to function, most of which are set to expire when your session expires. None of these provide us with any personal information.
The following information is provided by LivePerson. You will only encounter these cookies if you choose to use the live chat services across our site:
Two cookies with this name are created for different purposes. One includes a unique ID and creation time for the whole domain; the other contains the same unique ID, last visit time and last chat time. These IDs are randomly generated.

An acceptance test cookie.
Used for sites on the LivePerson Federation server. Details which element (container/session) is assigned to the visitor from the server.
