BACKGROUND AND BASIS OF PRESENTATION

BACKGROUND AND BASIS OF PRESENTATION

Cabot Microelectronics Corporation (“Cabot Microelectronics”, “the Company”, “us”, “we”, or “our”) is a leading global supplier of consumable materials to semiconductor manufacturers and pipeline companies. The Company's products play a critical role in the production of advanced semiconductor devices, helping to enable the manufacture of smaller, faster and more complex devices by its customers. The Consolidated Financial Statements included in this Report on Form 10-Q include the financial results of KMG Chemicals, Inc. (“KMG”) since the Company's acquisition of 100% of the outstanding stock of KMG (the "Acquisition") on November 15, 2018 (the “Acquisition Date”). We operate our business within two reportable segments: Electronic Materials and Performance Materials. The Electronic Materials segment consists of our heritage Chemical Mechanical Planarization ("CMP") slurries and polishing pads businesses, as well as the KMG electronic chemicals business.  The Performance Materials segment includes KMG’s heritage pipeline performance and wood treatment businesses, and our heritage QED business. For additional information, refer to Item 1 of Part I of our Annual Report on Form 10-K for the fiscal year ended September 30, 2019.

The unaudited Consolidated Financial Statements have been prepared by Cabot Microelectronics pursuant to the rules of the Securities and Exchange Commission ("SEC") and accounting principles generally accepted in the United States of America ("U.S. GAAP" or "GAAP").  In the opinion of management, these unaudited Consolidated Financial Statements include all adjustments, consisting of normal recurring adjustments, necessary for the fair statement of Cabot Microelectronics’ financial position as of June 30, 2020, cash flows for the nine months ended June 30, 2020 and June 30, 2019, and results of operations for the three and nine months ended June 30, 2020 and June 30, 2019.  The Consolidated Balance Sheets as of September 30, 2019 were derived from audited financial statements. The results of operations for the three and nine months ended June 30, 2020 may not be indicative of results to be expected for future periods, including the fiscal year ending September 30, 2020. This Report on Form 10-Q does not contain all of the note disclosures from our annual financial statements and should be read in conjunction with the Consolidated Financial Statements and related notes thereto included in our Annual Report on Form 10-K for the fiscal year ended September 30, 2019.

The Consolidated Financial Statements include the accounts of Cabot Microelectronics and its subsidiaries. All intercompany transactions and balances between the companies have been eliminated.

USE OF ESTIMATES

The preparation of financial statements and related disclosures in conformity with U.S. GAAP requires management to make judgments, assumptions and estimates that affect the amounts reported in the consolidated financial statements and accompanying notes. The accounting estimates that require management's most challenging and subjective judgments include, but are not limited to, those estimates related to impairment of long-lived assets, business combinations, asset retirement obligations, goodwill, other intangible assets, income taxes and contingencies. We base our estimates on historical experience, current conditions and on various other assumptions that we believe are reasonable under the circumstances. However, future events are subject to change and estimates and judgments routinely require adjustment. Actual results may differ from these estimates under different assumptions or conditions.
