Basis of Presentation

BASIS OF PRESENTATION

The accompanying consolidated financial statements include the accounts of Ultratech and our subsidiaries, all of which are wholly owned. Intercompany balances and transactions have been eliminated.

The U.S. dollar is the functional currency for all foreign operations. Foreign exchange gains and losses which result from the process of remeasuring foreign currency financial statements into U.S. dollars or from foreign currency exchange transactions during the period, are included in interest and other income, net. Net foreign exchange losses during the years ended December 31, 2015, 2014 and 2013 were $0.2 million, $0.4 million, and $0.3 million, respectively.

Our fiscal quarters in 2015 ended on April 4, 2015, July 4, 2014, October 3, 2015 and December 31, 2015. Our fiscal quarters in 2014 ended on March 29, 2014, June 28, 2014, September 27, 2014 and December 31, 2014.

We have evaluated subsequent events, as defined by Accounting Standard Codification (“ASC”) Topic 855, through February 26, 2016, which is the issuance date of our financial statements.

Use of Estimates

The preparation of the financial statements and related disclosures in conformity with accounting principles generally accepted in the United States requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities at the date of the consolidated financial statements. By their nature, these estimates and judgments are subject to an inherent degree of uncertainty. On an ongoing basis, management evaluates its estimates, including those related to inventory valuation and purchase order commitments, warranty obligations, asset retirement obligations, bad debts, estimated useful lives of fixed assets, intangible assets, asset impairment, income taxes, deferred income tax valuation allowance, stock-based compensation, and contingencies and litigation. Management bases its estimates on historical experience and on various other analyses and assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
