We have closed 2015 and sent everything to our CPA.  We had lots of stuff happen 12-2015 (separated from parent company, bought a new store location, etc) and so I have been waiting to make sure that we have CPA approval before moving on to 2016.  My January and February books are ready for closing; all I need to do is to run the period closing.  My boss is now asking for January and February to be closed.  If I run the period closing process for Jan and Feb and end up having to make a change to 12-2015,  will I be able to?  And would I then have to re-close January and February?  Thank you in advance!
