OK, I didn't know there was a grace period, lol. Or maybe they mistakenly stated March 30th instead of March 31st? I saw the 14th posted and also read this myself in the NOTIFICATION OF LATE FILING form NT-10K AISystems, Inc. (the “Registrant”) was unable, without unreasonable effort or expense, to file its Annual Report on Form 10-K for the year ended December 31, 2011 (the “Annual Report”) by the March 30, 2011 filing date applicable to smaller reporting companies due to a delay experienced by the Registrant in completing its financial statements and other disclosures in the Annual Report and its independent registered public accounting firm requires additional time to complete its review of the financial statements for the period ended December 31, 2011 to be incorporated in the Annual Report. The Registrant anticipates that it will file the Annual Report no later than the fifteenth calendar day following the prescribed filing date. http://www.otcmarkets.com/edgar/GetFilingHtml?FilingID=8516010
