MOCON, Inc. was unable to file its Annual Report on Form 10-K for the fiscal year ended December 31, 2013 within the 75 day prescribed period without unreasonable effort or expense. The delay is due to the implementation and transitional issues associated with a new ERP system that was installed in April 2013, along with delays in the completion of the Company's assessment of its internal controls over financial reporting.
