The quarterly periods shown above would be accurate for any company that operates on a calendar year. However, some companies operate on a fiscal year, and they have their own quarterly calendars that typically differ from those shown above. Companies sometimes choose to operate on a fiscal year if they operate in a business that is highly seasonal.

Where are Financial Quarters Reported?

Quarters are the time periods around which much of the financial world revolves. Companies issue quarterly reports that cover their performance during a quarter through a set of financial statements. Public companies in the United States file these reports via Securities and Exchange Commission Form 10-Q.

Quarterly reports help investors take the pulse of the companies they invest in. Comparing the quarterly information to the previous year's information for the same quarter can yield rich insight into how seasonal a company's business is, short-term performance and growth rates in a variety of measures, and information to compare with  similar companies.
