[1] | The above table does not reflect possible payments in connection with uncertain tax benefits of approximately $16.8 million including $10.6 million recorded as a reduction of long-term deferred tax assets and $6.2 million in long-term income taxes payable, as of December 31, 2012. As noted below in Note 17, “Income Taxes,” although it is possible that some of the unrecognized tax benefits could be settled within the next 12 months, the Company cannot reasonably estimate the outcome at this time.
[2] | With respect to the imputed financing obligation, the main components of the difference between the amount reflected in the contractual obligations table and the amount reflected on the Consolidated Balance Sheets are the interest on the imputed financing obligation and the estimated common area expenses over the future periods.
[3] | Leases and other contractual obligations include the Company's current operating lease commitments and commitment to purchase intellectual property from Elpida.
[4] | The Company has commitments with various software vendors for non-cancellable license agreements generally having terms longer than one year. The above table summarizes those contractual obligations as of December 31, 2012 which are also presented on the Company’s Consolidated Balance Sheet under current and other long-term liabilities.
[5] | In connection with recent acquisitions, the Company is obligated to pay retention bonuses to certain employees and contractors, subject to certain eligibility and acceleration provisions including the condition of employment. The remaining $33.3 million of CRI retention bonuses payable on June 3, 2013 and 2014 will be paid in cash or stock at the Company’s election.
