certain settlement agreements with relevant taxing authorities to pay approximately $96 million of these liabilities. Although it remains unclear as to when payments pursuant to these agreements will be made, some or all may be made in fiscal 2012. We cannot make a reasonably reliable estimate of the period in which the remainder of our unrecognized tax benefits will be settled or released with the relevant tax authorities, although we believe it is reasonably possible that certain of these liabilities could be settled or released during fiscal 2012.

Subsequent to fiscal 2011, we agreed to acquire certain companies for amounts that are not material to our business. We expect to close such acquisitions within the next twelve months.

We believe that our current cash, cash equivalents and marketable securities and cash generated from operations will be sufficient to meet our working capital, capital expenditures and contractual obligation requirements. In addition, we believe we could fund any future acquisitions, dividend payments and repurchases of common stock or debt with our internally available cash, cash equivalents and marketable securities, cash generated from operations, additional borrowings or from the issuance of additional securities.

Off-Balance Sheet Arrangements:     We do not have any off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that are material to investors.

Selected Quarterly Financial Data

Quarterly revenues, expenses and operating income have historically been affected by a variety of seasonal factors, including sales force incentive compensation plans. In addition, our European operations generally provide lower revenues in our first fiscal quarter because of the reduced economic activity in Europe during the summer. These seasonal factors are common in the high technology industry. These factors have caused a decrease in our first quarter revenues as compared to revenues in the immediately preceding fourth quarter, which historically has been our highest revenue quarter within a particular fiscal year. Similarly, the operating income of our business is affected by seasonal factors in a consistent manner as our revenues (in particular, our new software license and hardware systems products) as certain expenses within our cost structure are relatively fixed in the short-term. We expect these trends to continue in fiscal 2012. Our quarterly revenues, expenses and operating income were also impacted in the periods presented in the table below by our acquisition of Sun during the third quarter of fiscal 2010, which added a significant amount of revenues and expenses to our results of operations in comparison to our historical operating results.

The following tables set forth selected unaudited quarterly information for our last eight fiscal quarters. We believe that all necessary adjustments, which consisted only of normal recurring adjustments, have been included in the amounts stated below to present fairly
