Provider Name Purpose Type Lifetime
Google Analytics __utma This cookie is typically written to the browser upon the first visit. If the cookie has been deleted by the browser operator, and the browser subsequently visits pwc.com/gx, a new __utma cookie is written with a different unique ID. In most cases, this cookie is used to determine unique visitors to pwc.com/gx and it is updated with each page view. Additionally, this cookie is provided with a unique ID that Google Analytics uses to ensure both the validity and accessibility of the cookie as an extra security measure.
First Party Persistent 2 years from set/update.
Google Analytics __utmb
This cookie is used to establish and continue a user session with pwc.com/gx. When a user views a page on pwc.com/gx, the Google Analytics code attempts to update this cookie. If it does not find the cookie, a new one is written and a new session is established. Each time a user visits a different page on pwc.com/gx; this cookie is updated to expire in 30 minutes, thus continuing a single session for as long as user activity continues within 30-minute intervals. This cookie expires when a user pauses on a page on pwc.com/gx for longer than 30 minutes.
First Party Persistent  30 minutes from set/update.
Google Analytics
__utmc
Historically, this cookie operated in conjunction with the __utmb cookie to determine whether or not to establish a new session for the user. For backwards compatibility purposes with sites still using the urchin.js tracking code, this cookie will continue to be written and will expire when the user exits the browser. However, if you are debugging your site tracking and you use the ga.js tracking code, you should not interpret the existence of this cookie in relation to a new or expired session.
First Party Persistent Not set.
Google Analytics
__utmv
This cookie is not normally present in a default configuration of the tracking code. The __utmv cookie passes the information provided via the _setVar() method, which you use to create a custom user segment. This string is then passed to the Analytics servers in the GIF request URL via the utmcc parameter. This cookie is only written if you have added the _setVar() method for the tracking code on your website page.
