To make this site work properly, we sometimes place small data files called cookies on your device. Most big websites do this too.

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 login, language, 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?

• We use cookies to optimize your experience on our site. On some sites, they can remember your preferences or provide prompts that save you time. If you opt to turn the cookies off, some site functions may not be optimized
• We deploy cookies that we control and some that are third-party where we do not control their purpose.
• The cookies we use will not be used for anything beyond the purpose stated here. For some of our sites, the cookies change, as does their purpose.
• If you do not want to use these cookies, you can control and/or delete cookies as you wish – for details, see org. You can delete all cookies that are already on your computer and you can set most browsers to prevent them from being placed. If you do this, however, you may have to manually adjust some preferences every time you visit a site and some services and functionalities may not work.

An example of a cookie at work:

A number of our pages use cookies to enhance your experience. They can help 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)
• if you have agreed (or not) to our use of cookies on this site

Enabling these cookies is not 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. The cookie-related information is not used to identify you personally and the pattern data is fully under our control. These cookies are not used for any purpose other than those described here.
