______________________________________
(1) | The above table does not reflect possible payments in connection with uncertain tax benefits of approximately $19.9 million including $17.8 million recorded as a reduction of long-term deferred tax assets and $2.1 million in long-term income taxes payable, as of December 31, 2014. 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. The amount includes the amended Ohio lease and the amended Sunnyvale lease.
(3) | The Company has commitments with various software vendors for non-cancellable agreements generally having terms longer than one year.
(4) | In connection with 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 last payment of CRD retention bonuses was paid in cash during 2014.
