As of December 31, 2015 , our principal source of liquidity was cash and cash equivalents totaling $76.3 million . Our cash and cash equivalents are comprised primarily of money market funds. We fund our operations with cash on hand, cash flow from operations, borrowings at certain of our businesses and proceeds from sales of businesses and other assets. We expect that these sources of liquidity will be sufficient to fund our cash requirements over the next 12 months.
Bolt is expected to require additional borrowings, to fund its operations for the foreseeable future; historically, Bolt's debt funding has come primarily from Actua. On February 26, 2016, GovDelivery entered into a working capital revolving credit facility with Venture Bank, which matures on February 26, 2017 and provides for an advance amount of $5.0 million, subject to an interest rate of LIBOR plus 2%, adjusted daily. The facility is secured by the assets of GovDelivery.
Our future capital requirements will depend on many factors, including our customer and revenue growth rates, customer renewal activity, the timing and extent of research and development efforts, the timing and extent of sales and marketing activities, the decision whether to move into new geographical territories or markets, the introduction of new and enhanced solutions and the continuing market acceptance of our solutions.
As part of our business strategy, we currently expect to continue our aggressive sales and marketing campaigns and research and development initiatives. In addition, we actively source and intend to selectively pursue acquisitions, which we could fund using cash, debt, equity or some combination thereof. In connection with any such acquisition, and as part of our capital allocation program, we may purchase additional debt or equity securities from our existing businesses. Additionally, we may repurchase outstanding equity securities of our businesses from employees or other holders. We may also use cash or incur indebtedness to repurchase shares of our common stock or purchase additional equity interests. Our consolidated businesses may issue additional securities, repurchase outstanding shares or undergo a recapitalization of their debt or equity interests. Recapitalizations or equity issuances or repurchases by one of our businesses, including dilution associated with management equity grants, may change the ownership split that we and the noncontrolling interest holders have in that business. From time to time, we may be required to increase our ownership in one or more of our consolidated businesses as aresult of certain members of those businesses’ management teams exercising put rights. From time to time, we may also voluntarily seek to increase our ownership in one or more of our consolidated businesses. |
