Final answer:
A ski supplier in Vail, Colorado, would likely pick June 30 to end its fiscal year to align with their seasonal business cycle, ending after the peak winter season.
Step-by-step explanation:
A Vail, Colorado snow ski supplier would most likely choose June 30 to end its fiscal year. This date falls after the winter season, when their business activity, including sales and rentals of ski equipment, is likely to be lower.
By ending the fiscal year in the summer, the company can account for the majority of their yearly revenue which occurs during the winter months and can conduct inventory assessments and financial planning during a quieter period. This timing allows the business to prepare for the next peak season, which typically takes place during the colder months.
