The late filing is the CHRI 10K, which covers the year ending Dec 31, 2011. So it is doubtful the pending deal with HBRM (announced on Feb 21) has anything to do with the late filing.
10Q for Q1 is not due until May 15.
As I posted yesterday, CHRI has been late before, but always files, and almost always with excellent numbers. No worries here-- one of my biggest holdings-- buy on dips!
