Leasehold improvements, land and buildings, at cost	247.8	228.9

Furniture and equipment, at cost	67.2	63.4

Computer software, hardware, leasehold improvements, furniture, and equipment, at cost	571.9	582.0

Less: Accumulated depreciation	(422.2)	(437.0)

Computer software, hardware, leasehold improvements, furniture, and equipment, net	$149.7	$145.0

Answer the following question using the tabular data along with the context text, answer the question. You may include your reasoning, but be sure to finish with a JSON block exactly like {"answer": ["ANSWER"], "scale": "SCALE"} (leave "scale" empty if not applicable).

Background:
Computer Equipment, Software, Furniture, and Leasehold Improvements, Net
Computer equipment, software, and furniture are depreciated using the straight-line method over the estimated useful lives of the assets, which range from three to five years. Leasehold improvements are amortized on a straight-line basis over the shorter of their estimated useful lives or the lease term. Depreciation expense was $59.2 million in fiscal 2019, $67.6 million in fiscal 2018, and $73.1 million in fiscal 2017
Computer equipment, software, furniture, leasehold improvements and the related accumulated depreciation at January 31 were as follows:
Costs incurred for computer software developed or obtained for internal use are capitalized for application development activities, if material, and immediately expensed for preliminary project activities and post-implementation activities. These capitalized costs are amortized over the software’s expected useful life, which is generally three years.

Question: How much did the computer hardware, at cost change in 2019 compared to 2018?

((190.2-217.1)/217.1 ) * 100, therefore {"answer": "-12.39", "scale": "percent"}
