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 licenses and cloud software subscriptions segment) as certain expenses within our cost structure are relatively fixed in the short-term. We expect these trends to continue in fiscal 2015.

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 the results of such periods when read in conjunction with the consolidated financial statements and related notes included elsewhere in this Annual Report. The sum of the quarterly financial information may vary from the annual data due to rounding.

 

Stock Options and Restricted Stock-Based Awards

Our stock-based compensation program is a key component of the compensation package we provide to attract and retain certain of our talented employees and align their interests with the interests of existing stockholders. We historically have granted only stock options to our employees and any restricted stock-based awards outstanding were assumed as a result of our acquisitions.

We recognize that stock options and restricted stock-based awards dilute existing stockholders and have sought to control the number of stock options and restricted stock-based awards granted while providing competitive compensation packages. Consistent with these dual goals, our cumulative potential dilution since June 1, 2011 has been a weighted average annualized rate of 2.3% per year. The potential dilution percentage is calculated as the average annualized new stock options or restricted stock-based awards granted and assumed, net of stock options and restricted stock-based awards forfeited by employees leaving the company, divided by the weighted average
