Amendment Description | National Research Corporation, doing business as NRC Health, referred to in this report as “NRC Health,” the “Company,” “we,” “our,” “us” or similar terms, is filing this Amendment No. 1 on Form 10-K/A (this “Amendment”) to its Annual Report on Form 10-K for the year ended December 31, 2020, originally filed with the Securities and Exchange Commission (the “SEC”) on March 5, 2021 (the “Original Filing”). We are filing this Amendment for the sole purpose of including the information required by Items 10 through 14 of Part III of Form 10-K (the “Part III Information”) and to delete the disclosures regarding incorporation by reference on the front cover page of the Original Filing. The Part III Information was previously omitted from the Original Filing in reliance on General Instruction G(3) to Form 10-K, which permits the Part III Information to be incorporated in Form 10-K by reference from our definitive proxy statement if such statement is filed no later than 120 days after our fiscal year-end. We are filing this Amendment to provide the Part III Information in our Form 10-K because a definitive proxy statement containing such information will not be filed by the Company within 120 days of the end of the fiscal year covered by the Form 10-K. | ||
