Net cash provided by (used in) financing activities
The changes in cash flows from financing activities primarily relate to borrowings and payments under debt obligations, as well as stock repurchase and stock option exercise activities.
2007 compared to 2006: Net cash provided by financing activities increased primarily due to proceeds received from issuance of convertible debentures and an increase in proceeds received from the issuance of common stock from stock option exercises and employee stock purchase plan purchases, partially offset by an increase in cash spent for stock repurchase activities and repayment of short-term debt under the Credit Facility.
2006 compared to 2005: Net cash provided by financing activities increased primarily due to proceeds received from draw-down of the Credit Facility, partially offset by a decrease in cash spent for stock repurchase activities and for repayment of short-term debt under the Credit Facility.
As of December 31, 2007, restricted cash and investments primarily include $45.0 million related to a trust established during 2004 for our director and officer liability self-insurance coverage.
As of December 31, 2007, we have pledged approximately $2.5 million as collateral for standby letters of credit that guarantee certain of our contractual obligations, primarily relating to our real estate lease agreements, the longest of which is expected to mature in 2014. Of the $2.5 million pledged as of December 31, 2007, approximately $2.0 million is classified as short-term restricted cash and is included in cash and cash equivalents. In January 2008, the collateral associated with stand-by letters of credit was released.
In 2006, we entered into a credit agreement with a syndicate of banks and other financial institutions related to a $500.0 million senior unsecured revolving credit facility (the Facility), under which VeriSign, or certain
designated subsidiaries may be borrowers. As of December 31, 2007, there were no outstanding borrowings under the Facility. Any future borrowings under the Facility will be used for working capital, capital expenditures, permitted acquisitions and repurchases of our common stock and other lawful corporate purposes.
We believe existing cash and cash equivalents, together with funds generated from operations should be sufficient to meet our working capital, capital expenditure requirements and to service our debt for the next 12 months. Our philosophy regarding the maintenance of a balance sheet with a large component of cash, cash equivalents and short-term investments reflects our views on potential future capital requirements relating to expansion of our businesses, acquisitions, and share repurchases. We regularly assess our cash management approach and activities in view of our current and potential future needs.
