Background

Mallinckrodt plc and its subsidiaries (collectively, "Mallinckrodt" or "the Company") is a global business that develops, manufactures, markets and distributes specialty pharmaceutical products and therapies.

On February 22, 2018, the Company's Board of Directors authorized commencement of a process to dispose of (1) its Specialty Generics business comprised of the previously reported Specialty Generics segment, with the exception of BioVectra, Inc. - a wholly-owned subsidiary of the Company that operates a contract manufacturing business in Canada ("BioVectra"), (2) certain of its non-promoted brands business, which was previously reflected in the Specialty Brands segment; and (3) its ongoing, post-divestiture supply agreement with the acquirer of the contrast media and delivery systems ("CMDS") business, which was previously reflected in the Other non-operating segment (referred to collectively as the "Specialty Generics Disposal Group"). The Company evaluated the criteria prescribed by United States ("U.S.") Generally Accepted Accounting Principles ("GAAP") for recording a disposal group as held for sale and discontinued operations. This criteria was met during the three months ended March 30, 2018, and as a result, prior year balances have been recast to present the financial results of the disposal group as a discontinued operation.

As the Specialty Generics Disposal Group is reported as a discontinued operation, the Company's continuing operations are limited to the results of operations from the Specialty Brands segment. The Specialty Brands segment markets branded pharmaceutical products for autoimmune and rare diseases in the specialty areas of neurology, rheumatology, nephrology, ophthalmology and pulmonology; immunotherapy and neonatal respiratory critical care therapies, analgesics and gastrointestinal products. The Company's diversified, in-line portfolio of both marketed and development products is focused on patients with significant unmet medical needs.

The Company owns or has rights to use the trademarks and trade names that are used in conjunction with the operation of its business. One of the more important trademarks that the Company owns or has rights to use that appears in this Quarterly Report on Form 10-Q is "Mallinckrodt," which is a registered trademark or the subject of pending trademark applications in the U.S. and other jurisdictions. Solely for convenience, the Company only uses the ™ or ® symbols the first time any trademark or trade name is mentioned in the following notes. Such references are not intended to indicate in any way that the Company will not assert, to the fullest extent permitted under applicable law, its rights to its trademarks and trade names. Each trademark or trade name of any other company appearing in the following notes is, to the Company's knowledge, owned by such other company.

Basis of Presentation

The unaudited condensed consolidated financial statements have been prepared in U.S. dollars and in accordance with GAAP. The preparation of the unaudited condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities, disclosure of contingent assets and liabilities and the reported amounts of revenues and expenses. Actual results may differ from those estimates. The unaudited condensed consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries and entities in which they own or control more than 50% of the voting shares, or have the ability to control through similar rights. All intercompany balances and transactions have been eliminated in consolidation and all normal recurring adjustments necessary for a fair presentation have been included in the results reported. The results of entities disposed of are included in the unaudited condensed consolidated financial statements up to the date of disposal, and where appropriate, these operations have been reported in discontinued operations. Divestitures of product lines and businesses not meeting the criteria for discontinued operations have been reflected in operating income. The fiscal year end balance sheet data was derived from audited consolidated financial statements, but do not include all of the annual disclosures required by GAAP; accordingly these unaudited condensed consolidated financial statements should be read in conjunction with the Company's audited annual consolidated financial statements included in its Annual Report on Form 10-K for the period ended December 29, 2017 filed with the Securities and Exchange Commission ("SEC") on February 27, 2018.
