A ski resort is open only during the months of December through March - the winter resort season. If the books are kept on the basis of a calendar year, the accounting period would split the season, and distortion of income would result. So, what would appear as a profit as of December 31, the close of the calendar year, may turn out to be a loss, or vice versa, when the entire season, December through March, is considered.
Moreover, the use of the calendar year would require the operators to take inventories and make other determinations in the middle of the season when they have the least amount of time available. The use of a fiscal year that included the entire season would make it possible to avoid these difficulties.
