COMMITMENTS AND CONTINGENCIES

Lease obligations

The Company leases warehouse space, office space and equipment under various capital and operating leases over periods ranging from one to ten years. Certain of these leases provide for scheduled rent increases based on price-level factors. The Company generally does not enter into leases that call for contingent rent. In most cases, the Company expects that, in the normal course of business, leases will be renewed or replaced. Net rent expense relating to the Company’s non-cancelable operating leases for the fiscal years ended May 31, 2019, 2018 and 2017 was $22.8, $26.0 and $24.9, respectively. Net rent expense represents rent expense reduced for sublease and rental income.

Amortization of assets under capital leases for buildings and equipment was $1.6, $1.3 and $1.1 for the fiscal years ended May 31, 2019, 2018 and 2017, respectively, and is included in Depreciation and amortization expense.

The Company had open standby letters of credit of $5.3 issued under certain credit lines as of May 31, 2019 and 2018, in support of its insurance programs. These letters of credit are scheduled to expire within one year; however, the Company expects that substantially all of these letters of credit will be renewed, at similar terms, prior to their expiration.

Contingencies

Various claims and lawsuits arising in the normal course of business are pending against the Company. The Company accrues a liability for such matters when it is probable that a liability has occurred and the amount of such liability can be reasonably estimated. When only a range can be estimated, the most probable amount in the range is accrued unless no amount within the range is a better estimate than any other amount, in which case the minimum amount in the range is accrued. Legal costs associated with litigation are expensed in the period in which they are incurred. The Company does not expect, in the case of those various claims and lawsuits arising in the normal course of business where a loss is considered probable or reasonably possible, that the reasonably possible losses from such claims and lawsuits (either individually or in the aggregate) would have a material adverse effect on the Company’s consolidated financial position or results of operations.

On June 21, 2018, the U.S. Supreme Court issued its opinion in South Dakota v. Wayfair, Inc. et. al., reversing prior precedent, in particular Quill Corp. v. North Dakota (1992), which held that states could not constitutionally require retailers to collect and remit sales or use taxes in respect to mail order or internet sales made to residents of a state in the absence of the retailer having a physical presence in the taxing state. As a result, the Company will now have an obligation, at least on a going forward basis, to collect and remit sales and use taxes, primarily in respect to sales made through its school book club channel, as well as certain sales made through its ecommerce internet sites, to residents in states that the Company has not previously remitted sales or use taxes based on its having no physical presence in such states. In the majority opinion, several factors were discussed in support of the Court’s reasoning that the collection of sales and use taxes from out-of-state retailers did not constitute an undue burden on interstate commerce, including the fact that South Dakota did not require retroactive application of its statute. However, the question of retroactive application, as well as certain other factors noted in the opinion are subject to how the states, on a state-by-state basis, interpret and apply the Court’s decision in their implementation of their respective state laws or regulations addressing the collection of sales and use taxes from out-of-state retailers. As a result, how the decision will affect the Company will depend on the positions taken by the states, on a state-by-state basis, relating to the retroactive application of the obligation to collect such taxes, as well as other factors noted in the opinion. The Company is not in a position at this time to determine or estimate the probable effect of the Court’s decision for retroactive application. However, depending on the positions taken by the respective states, the number of states taking such positions and the time periods for retroactive application, as well as the treatment by the states of other factors noted in the Court’s opinion, the Company could be significantly impacted by the states’ interpretations and applications of the Court’s decision. As of May 31, 2019, the Company’s school book club channel remitted sales taxes in 39 states. Any on-going or future litigation with states relating to sales and use taxes could be impacted favorably or unfavorably by the Court’s decision in future fiscal periods.
