A cookie consists of information sent by a web server to a web browser, and stored by the
browser. The information is then sent back to the server each time the browser requests a page
from the server. This enables the web server to identify and track the web browser. We use both
“session” cookies and “persistent” cookies on the website. We will use the session cookies to:
keep track of you whilst you navigate the website; and we will use the persistent cookies to:
enable our website to recognise you when you visit.

Session cookies will be deleted from your computer when you close your browser. Persistent
cookies will remain stored on your computer until deleted, or until they reach a specified
expiry date. We use Google Analytics to analyse the use of this website. Google Analytics
generates statistical and other information about website use by means of cookies, which are
stored on users' computers. The information generated relating to our website is used to create
reports about the use of the website. Google will store this information.

We use the following cookies on this website, for the following purposes:

NAME: __utma
This cookie originates from Google Analytics and is written to the browser upon the first visit
to the site from specific web browser. If the cookie has been deleted by the browser operator,
and the browser subsequently visits the site, a new __utma cookie is written with a different
unique ID. This cookie is used to determine unique visitors to the site 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.
Expiration: 2 years from set/update.

NAME: __utmb
This cookie originates from Google Analytics and is used to establish and continue a user
session with your site. When a user views a page on the site, 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 ise stablished. Each time a user visits a different page on the site, 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 the site for longer than 30 minutes. Expiration: 30 minutes from set/update.

NAME: __utmc
This cookie originates from Google Analytics and operates in conjunction with the __utmb
cookie to determine whether or not to establish a new session for the user. In particular,
this cookie is not provided with an expiration date, so it expires when the user exits the
browser. Should a user visit the site, exit the browser and then return to the website within
30 minutes, the absence of the __utmc cookie indicates that a new session needs to be
established, despite the fact that the __utmb cookie has not yet expired. Expiration: Not set.

NAME: __utmz
This cookie originates from Google Analytics and stores the type of referral used by the visitor
to reach the site, whether via a direct method, a referring link, a website search, or a campaign
such as an ad or an eMail link. It is used to calculate search engine traffic, advertisement
campaigns and page navigation within your the site. The cookie is updated with each page
view to your site. Expiration: 6 months from set/update.

NAME: __utmv
This cookie originates from Google Analytics and is not normally present in a default
configuration of the tracking code. The __utmv cookie passes the information provided via
the _setVar() method, when used to create a custom user segment. This string is then passed
to the Analytics servers in the GIF request URL via the utmcc parameter.
Expiration: 2 years from set/update.

NAME: __utmx
This cookie originates from Google Analytics and is used by Website Optimizer and only set
when the Website Optimizer tracking code is installed. Expiration: 2 years from set/update.
