Canada Adjust a 15-month fiscal year to 12 months.

[ArtemisDiana]

Hi all,

I am currently working on an assignment with financial statements from 2012-2020. However, prior to 2016, the company reported their financial statements with a fiscal year of 15 months (switched to calendar years). How do I adjust the COGS etc. from 15 months to 12 months? I have access to information regarding the calendar year net sales for the years 2012-2020 but not COGS and other expenses.

Thank you!
