COMMITMENTS

We lease certain sales offices, showrooms, warehouses and equipment under non-cancelable operating leases that expire at various dates through 2026. During the normal course of business, we have entered into sale-leaseback arrangements for certain facilities. Accordingly, these leases are accounted for as operating leases, and the related gains from the sale of the properties are recorded as deferred gains and are amortized over the lease term. Total deferred gains are included as a component of Other long-term liabilities on the Consolidated Balance Sheets and amounted to $1.5 as of February 24, 2017 and $3.8 as of February 26, 2016.

Gross rent expense under all non-cancelable operating leases was $49.8, $48.8 and $50.5 for 2017, 2016 and 2015, respectively. Sublease rental income was $4.0, $5.2 and $5.3 for 2017, 2016 and 2015, respectively.

Our estimated future minimum annual rental commitments and sublease rental income under non-cancelable operating leases as of February 24, 2017 are as follows:
