The message is about the new Configure Certificate Trust - the FacebookCA rule is set to expire on 12/30/2013.
If you open up EMET 4.0, click on TRUST ( CONFIGURE CERTIFICATE TRUST) --> Click on the Pinning Rules Tab --> Under Rule Expiration for FacebookCA you can change the rule to expire next month or later and the message will go away. You can
set it to when the YahooCA rule will expire on 3/13/2014 if you like and you won't receive the message anymore.
Not sure if the default template rules will be updated automatically or if they need to be manually updated. The Certificate stuff is all new to Emet 4.0 and I have yet to read up on all the configuration settings, etc.
You might not be on facebook but many websites incorporate facebook logins and like buttons on them, thus is why you see the EMET message since the default template rule for FacebookCA expired today.
