(1): Net income (loss) per share is computed independently for each of the quarters presented. Therefore, the sum of the quarterly basic and diluted net income (loss) per share amounts do not equal the annual basic and diluted net income (loss) per share amount for fiscal 2013 or fiscal 2012, respectively.
(2): During the quarter ended June 30, 2012, the Company received $10.5 million, net of deductibles, from the insurance company against the claim filed for business interruption and miscellaneous property losses arising due to flooding at one of the Company's manufacturing partner, of which $9.4 million was recorded as other income in Interest and other income (expense), net.

(3): During the quarter ended June 30, 2012, the Company recorded an impairment of long-lived assets of $21.5 million related to its Hologram Business which has been presented as Loss from discontinued operations, net of tax in accordance with the authoritative guidance. See "Note 19. Discontinued Operations" for more detail.
(4): During the quarter ended March 30, 2013, the Company approved a strategic plan to exit CommTest's legacy low-speed wireline product line, which resulted in a $2.2 million charge for accelerated amortization of related intangibles of which $1.8 million and $0.4 million is included in Amortization of acquired technologies and Amortization of other intangibles in the Consolidated Statement of Operations, respectively. In addition, the Company incurred $11.3 million of inventory related charges included in Cost of sales in the Consolidated Statement of Operations primarily related to the write-off of inventory no longer being sold due to the legacy low-speed wireline product line exit.
(5): During the quarter ended June 29, 2013, the Company determined that it is more likely than not that a portion of the deferred tax assets of a non-U.S. jurisdiction will be realized after considering all positive and negative evidence. Accordingly, a deferred tax valuation allowance release of $107.9 million was recorded as an income tax benefit during the quarter.
