Acquisitions [Abstract]
Acquisitions	6. Acquisitions: On September 30, 2016, the Company acquired the net assets of Atypon Systems, Inc. ("Atypon"), a Silicon Valley-based publishing-software company, for approximately $121 million in cash, net of cash acquired. Atypon is a publishing software and service provider that enables scholarly and professional societies and publishers to deliver, host, enhance, market and manage their content on the web. Atypon is headquartered in Santa Clara, CA, with approximately 260 employees in the U.S. and EMEA. Atypon provides services through Literatum, an innovative platform that primarily serves the scientific, technical, medical and scholarly industry. This software gives publishers direct control over how their content is displayed, promoted and monetized on the web. Atypon generated over $31 million in calendar year 2015 revenue. Literatum hosts nearly 9,000 journals, 13 million journal articles and more than 1,800 publication web sites for over 1,500 societies and publishers, accounting for a third of the world's English-language scholarly journal articles. The $121 million purchase price was allocated to identifiable long-lived intangible assets, including customer relationships ($14 million), software ($28 million), goodwill ($70 million) and trademarks ($6 million), with the remainder allocated to working capital ($3 million). The fair value of intangible assets and technology acquired was based on management's assessment performed with the assistance of a third party valuation consultant. Goodwill represents the excess of the purchase price over the fair value of net assets acquired and comprises the estimated value of Atypon's workforce, unidentifiable intangible assets and the fair value of expected synergies. The identifiable long-lived intangible assets with definitive lives are primarily amortized over a weighted average estimated useful life of approximately 12 years. The Company finalized its purchase accounting for Atypon on July 31, 2017. Atypon's revenue and operating loss included in the Company's results for the three months ended July 31, 2017 were $8.3 million and $0.5 million, respectively.
