Hello everyone,

I have a question: for my research it's is relevant that there are no fiscal years-end changes from year t-1(previous year) to t(current year) and year t+1(future year). For example: if from fyear 2011 to fyear 2019 the datadate changes to 31sept2011 instead of 31may2011, fyear 2011 is not comparable with fyear 2010 anymore because fiscal year-end(datadate) differs from each other. Therefore fyear 2010 and fyear 2011 have to be deleted from my dataset because each firm year must have a comparable datadate in year t-1 and in year t+1. Does anyone know how I can realize this is my dataset?
