Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Legal Matters 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 exists 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. In the third quarter, the Company entered into settlement agreements related to photo copyright infringement cases. The Company recognized $2.4 in total, of which $1.4 remained accrued as of February 29, 2020. In the first quarter, based on the status of negotiations, an alleged patent infringement claim settlement became probable and estimable. As such, an accrual of $1.5 was recognized in the Financial Statements in the first quarter of fiscal 2020. The settlement was subsequently concluded in the second quarter of fiscal 2020. Sales Tax Matters 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 now has an obligation, at least on a go forward basis, based on each state's enforcement date, 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 had not previously remitted sales or use taxes based on 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, the effect of the decision on the Company depends 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 continues to monitor its compliance based on anticipated enforcement dates and an assumption as to each state's likely interpretation and application of the Court's decision. As the Company continues to monitor each state, the staggered enforcement dates, and the progress towards compliance, expenses will be incurred by the Company. As of February 29, 2020, the Company’s school book club channel remits sales taxes in 44 states and the District of Columbia compared to 38 states and the District of Columbia in the prior fiscal year quarter ended February 28, 2019. The Company remits sales tax to all required states. Any on-going or future litigation with states relating to sales and use taxes could be impacted favorably or unfavorably by legislative action in future fiscal periods. COVID-19 During and subsequent to the third quarter of the current fiscal year, the novel coronavirus strain, known as COVID-19, continues to spread across the globe at an increasing rate. Measures taken by governmental authorities and private actors to limit the spread of this virus may interfere with the ability of the Company's employees, suppliers, and other business providers to carry out their assigned tasks or supply materials at ordinary levels of performance relative to the conduct of the business which may cause a material curtailment to certain business operations. Moreover, as a large part of the Company's business involves sales of books and other products in schools and school facilities, as well as through school districts, if COVID-19 related measures result in widespread and lengthy school closings, the Company's consolidated results of operations and financial condition will be adversely impacted. In particular, in the context of the book fair channel, such closings may lead to cancellation of a significant number of book fairs which are not rebooked or cannot be held during the current school year and, in the context of the book clubs channel, such closings could result in a significant decrease in the participation by teacher sponsors in scheduled book club offerings. In the case of the Education segment, the last quarter of the fiscal year, currently ending May 31, 2020, is normally a significant quarter as school administrators and other educational personnel, prior to breaking for the summer, order products for immediate shipment in preparation for the following academic school year. These orders could be significantly impacted by the absence from the schools of such administrators and other educational personnel resulting from school closings. The International segment is also subject to the same risks, due to the temporary closing of English language learning centers in China, as well as disruption in the direct sales business in other parts of Southeast Asia, resulting from measures imposed to combat the spread of COVID-19. The Company is not currently aware of any loss contingencies related to this matter that would require recognition in the third quarter of fiscal 2020.
