We have generated net cash from operations during each quarter since the second quarter of 2001. Many factors will impact our ability to continue to generate and grow cash from our operations including, but not limited to, the number of subscribers who sign up for our service and the growth or reduction in our subscriber base. In addition, we may have or otherwise choose to lower our prices and increase our marketing expenses in order to grow faster or respond to competition. Although we currently anticipate that cash flows from operations, together with our available funds, will be sufficient to meet our cash needs for the foreseeable future, we may require or choose to obtain additional financing. Our ability to obtain financing will depend on, among other things, our development efforts, business plans, operating performance and the condition of the capital markets at the time we seek financing.
Our primary source of liquidity has been cash from operations, which consists mainly of net income adjusted for non-cash items such as amortization of our content library, depreciation of property and equipment and stock-based compensation related to the issuance of common stock. Our primary uses of cash include our stock repurchase programs, postage and packaging
