• Revenue estimated to be in the range of $840 million to $900 million
• Non-GAAP gross margin expected to be between 65.5% and 66.0%
• Non-GAAP operating expenses expected to be slightly up sequentially
• Non-GAAP interest and other expense expected to be between $20 million and $25 million

With respect to the forward-looking information presented on a non-GAAP basis, the Company is unable to provide a quantitative reconciliation to GAAP because the items that would be included or excluded, other than those described below, are difficult to predict and estimate and are primarily dependent on future events, including costs relating to the consummation and planned integration of the Company’s pending acquisition of Linear Technology Corporation, which is expected to close by the end of the Company’s second fiscal 2017 quarter. Known reconciling items are:

• Non-GAAP gross margin excludes $2.5 million of amortization of purchased intangible assets and depreciation of step up value on purchased fixed assets;
• Non-GAAP operating expenses exclude $17.5 million of amortization of purchased intangible assets and depreciation of step up value on purchased fixed assets;
• Non-GAAP tax rate excludes $1.0 million provision for income taxes which represents the tax effects of the reconciling items noted in the two bullets above; and
• Non-GAAP earnings per share excludes $0.06, which represents the estimated impact of the amortization of purchased intangible assets and depreciation of step up value on purchased fixed assets, net of tax, associated with the non-GAAP adjustments noted above on a per share basis.

Non-GAAP Financial Information
This release includes non-GAAP financial measures that are not in accordance with, nor an alternative to, generally accepted accounting principles and may be different from non-GAAP measures used by other companies. In addition, these non-GAAP measures are not based on any comprehensive set of accounting rules or principles.

Schedules E and F of this press release provides the reconciliation of the Company’s historical non-GAAP measures to their most comparable GAAP measures.

Management uses non-GAAP measures internally to evaluate the Company’s operating performance from continuing operations against past periods and to budget and allocate resources in future periods. These non-GAAP measures also assist management in evaluating the Company’s core business and trends across different reporting periods on a consistent basis. Management also uses these non-GAAP measures as the primary performance measurement when communicating with analysts and investors regarding the Company’s earnings results and outlook and believes that the presentation of these non-GAAP measures is useful to investors because it provides investors with the operating results that management uses to manage the Company and enables investors and analysts to evaluate the Company’s core business. Management also believes that the non-GAAP liquidity measure free cash flow is useful both internally and to investors because it provides information about the amount of cash generated after capital expenditures that is then available to repay debt obligations, make investments and fund acquisitions, and for certain other activities.

The following items are excluded from our non-GAAP gross margin, non-GAAP operating expenses, non-GAAP operating income, non-GAAP operating margin, and non-GAAP diluted earnings per share:

Acquisition-Related Expenses: Expenses incurred as a result of prior period acquisitions primarily include expenses associated with the fair value adjustments to property, plant and equipment and amortization of acquisition related intangibles, which include acquired intangibles such as purchased technology and customer relationships. We excluded these costs from our non-GAAP measures because they relate to a specific transaction and are not reflective of our ongoing financial performance.

Stock-Based Compensation Expense: In fiscal 2015, the Company recorded $3.0 million of stock-based compensation expense for one of its former executive officers due to the accelerated vesting of restricted stock units and a reduction in the requisite service period for stock options in accordance with the terms of the applicable agreements. In addition, in fiscal 2015, the Company recorded $1.3 million of stock-based compensation expense due to the accelerated vesting of restricted stock units and stock options in conjunction with the restructuring charge recorded in the fourth quarter of fiscal 2014.
