What are cookies?
A cookie is a small text file that a website saves on your computer or mobile device when you visit the site. It enables the website to remember your actions and preferences (such as log in, language and font size and other display preferences) over a period of time, so you don't have to keep re-entering them whenever you come back to the site or browse from one page to another.
How do we use cookies?
A number of our pages use cookies to remember:
• your display preferences, such as contrast color settings or font size
• if you have already replied to a survey pop-up that asks you if the content was helpful or not (so you won't be asked again)
The following 3rd-party cookies are also used on our pages:
• YouTube (embedded videos): PREF, VISITOR_INFO1_LIVE, YSC
Enabling these cookies is not strictly necessary for the website to work but it will provide you with a better browsing experience. You can delete or block these cookies, but if you do that some features of this site may not work as intended.
Do we use other cookies?
Some of our pages or sub-sites may use additional or different cookies to the ones described above.
