Compact Privacy Policies are implemented as an additional P3P header in the HTTP protocol.
The policies consist of a list of 3 character policy codes followed by an optional 4th
character that can be an i (opt-in), o (opt-out), or a (always). View our
Platform for Privacy Preferences page for more information
about Privacy Policies.
Browsers may require a Compact Privacy Policy for third party media including
images on a page that attempt to use cookies. If the policy is missing or unacceptable
a red warning flag will typicall be displayed in the bottom status bar of the browser.

Privacy Warning Indicator in IE and Firefox: 
This utility provides a way to quickly test browser privacy warning compliance, or to
determine what privacy policies are acceptable for third-party images. The red image
below is served by a third-party source that attempts to set a browser cookie. Change
the policy and watch for the alert at the bottom of your browser.
Many browsers have a privacy policy compliance bug.
Setting a CP to 'FIN' will cause a warning to appear as expected.
Adding an 'i' (FINi) for 'opt-in' or 'o'
(FINo) for 'opt-out' causes the warning to go away,
which may be acceptable.
Adding an 'a' (FINa) for 'always' which is the default and is the same as 'FIN', does not make the warning reappear! That means that sites could be compliant in stating they track your financial information, but your browser will not warn you! First discovered 3/2004.
