_________________________________________
(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 September 30, 2013. As noted below in Note 14, “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 condensed consolidated balance sheets are the interest on the imputed financing obligation and the estimated common area expenses over the future periods. Additionally, the amount includes the amended Ohio lease and the amended Sunnyvale lease.
(3) | 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 September 30, 2013 which are also presented on the Company’s condensed consolidated balance sheet under current and other long-term liabilities.
(4) | In connection with its 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 $16.9 million of CRI retention bonuses payable on June 3, 2014 can be paid in cash or stock at the Company’s election.
