st: panel data-dropping all observations for the identifier when certain variable value is missing

Dear all,
I am struggling with the following:
I have firm-year observations for the years 2003-2010. For cases where the last value for the variable <offdate>, which is a variable containing dates, is older than a
date in 2008 (so date in 2007, 2006,...) then stata shall drop the firm/identifier at all, so for
every year. Then, I want stata to show me for every firm/identifier the last entry for the variable <offdate>, which could then either be a date in 2008, 2009 or 2010. Which commands could help me doing this?
Thanks,
Sabrina
