Please click on the “Your Privacy Choices” icon in the lower left corner of this page to find out more about the categories of cookies we use on our Services and options you may have to change your default settings. Please note, however, that changing your cookie preferences will not automatically delete cookies that were already placed on your computer or mobile device before you made the change; those previously set cookie files may remain on your device, and refreshing your browser or revising our Services may be needed for the browser to recognize and apply your updated preferences to those existing cookies. In some instances, blocking certain cookies may impact your experience with the Services offered.
This Cookie Statement forms part of our overall Privacy Statement. Capitalized terms used here have the definitions set out in the Privacy Statement.
We may use the following types of cookies and similar technologies on our websites:
These cookies are necessary for the website to function and cannot be switched off in our systems. They are usually only set in response to actions made by you which amount to a request for services, such as setting your privacy preferences, logging in, or filling in forms.

Targeting cookies may be implemented through our Services by our advertising partners. They may be used by those companies to track your browser across other websites and build a profile of your interests and show you relevant ads on other websites. They are based on uniquely identifying your browser and internet device, but they do not store Personal Information that directly identifies you. If you do not allow these cookies, you will experience less targeted advertising.

They can track your browser across other websites and build a profile of your interests. They may impact the content and messages you see on other websites you visit. If you do not allow these cookies, you may not be able to use or see these sharing tools.

Some of these cookies may be placed by third-party service providers or embedded in our email communications to help determine the effectiveness of our advertising campaigns or email communications and to understand how you interact with them. The use of cookies by third-party service providers is within their control and not ours.
