the 10k for the end of the fiscal year ending Dec
Post# of 1012
(by filing NT forms companies can delay the due date for a 10k by 15 days but zn has not been doing that)
ZN has a practice of filing 10q's and 10k's before the deadline- often well before the deadline
last year ZN filed their 10k on Mar 12- the easiest way you can verify is on otcmarkets.com - ZN -disclosure
