About the metric
What depreciation and amortization mean
Depreciation and amortization allocate the cost of tangible and intangible assets over their useful lives. These non-cash expenses reduce reported earnings and are commonly added back when calculating EBITDA and operating cash flow.
Calculation and source
Reported depreciation and amortization
TickerStat uses a combined depreciation and amortization value when reported. If a company reports the two components separately for an aligned period, they are added together without duplicating overlapping facts. Fiscal periods can differ from calendar years, so exact period-end dates are included.
