XYZ Company, a 'for-profit' business, had revenues of $60 million in 2019. Expenses other than depreciation totaled 55 percent of revenues, and depreciation expense was $5.0 million. XYZ Company, must pay taxes at a rate of 25 percent of pretax (operating) income. All revenues were collected in cash during the year, and all expenses other than depreciation were paid in cash.

Depreciation originally was $5 million; however, a change in the depreciation schedule (still within GAAP) has now made the depreciation expense DOUBLE.

Based on this change in depreciation expense, what would XYZ's profit margin be?
