Discontinued Operations and Disposal Groups [Abstract]
SALE OF BUILDING	SALE OF BUILDINGOn October 2, 2018, we sold our 130,000 square feet corporate headquarters building in Minnetonka, Minnesota to Minnetonka Leased Housing Associates II, LLLP. The sale price was $10.0 million in cash adjusted for certain selling costs and an escrow for the leaseback of the building for four months. As a result of this sale, we recorded a gain of $4.4 million ($3.4 million net of tax) in the first quarter of fiscal 2019, which is recorded in general and administrative expense. During the fiscal year ended September 30, 2019, we paid $5.8 million for leasehold improvements to build out our new headquarters space. These improvements are being depreciated over 10 years, which is the estimated useful life of the improvements.

The entire disclosure related to a disposal group. Includes, but is not limited to, a discontinued operation, disposal classified as held-for-sale or disposed of by means other than sale or disposal of an individually significant component.
