Sales and Marketing
Sales and marketing expense increased 1% to $166.0 million for the three months ended March 31, 2019 from $163.8 million for the three months ended March 31, 2018. The prior year period excludes $9.7 million of Legacy Worldpay sales and marketing expense prior to our acquisition. When including the 2018 period prior to our acquisition, the decrease in sales and marketing expense is primarily attributable to sales efficiencies, partially offset by higher residual payments to referral partners.

Liquidity and Capital Resources
Our liquidity is funded primarily through cash provided by operations, debt and a line of credit, which is generally sufficient to fund our operations, planned capital expenditures, tax distributions made to our non-controlling interest holders, required payments under our TRA agreements, debt service and acquisitions. As of March 31, 2019, our principal sources of liquidity consisted of $107.9 million of cash and cash equivalents and $1.0 billion of availability under the revolving portion of our senior secured credit facilities. Our total indebtedness, including finance leases, was $7.5 billion as of March 31, 2019.
We do not intend to pay cash dividends on our Class A common stock in the foreseeable future. Worldpay, Inc. is a holding company that does not conduct any business operations of its own. As a result, Worldpay, Inc.’s ability to pay cash dividends on its common stock, if any, is dependent upon cash dividends and distributions and other transfers from Worldpay Holding. The amounts available to Worldpay, Inc. to pay cash dividends are subject to the covenants and distribution restrictions in its subsidiaries’ loan agreements.
In addition to principal needs for liquidity discussed above, our strategy includes investing in and leveraging our integrated business model and technology platform, broadening and deepening our distribution channels, entry into new geographic markets and development of additional payment processing services. Our near-term priorities for capital allocation include debt reduction, investing in our operations to support organic growth, and share repurchases. Long-term priorities remain unchanged and include investing for growth through strategic acquisitions and returning excess capital to shareholders.
We anticipate that to the extent that we require additional liquidity, it will be funded through the incurrence of other indebtedness, equity financings or a combination thereof. We cannot assure you that we will be able to obtain this additional liquidity on reasonable terms, or at all. Additionally, our liquidity and our ability to meet our obligations and fund our capital requirements are also dependent on our future financial performance, which is subject to general economic, financial and other factors that are beyond our control. Accordingly, we cannot assure you that our business will generate sufficient cash flow from operations or that future borrowings will be available under our credit facilities or otherwise to meet our liquidity needs. If we decide to pursue one or more significant acquisitions, we may incur additional debt or sell additional equity to finance such acquisitions.
However, as a result of the Merger Agreement with FIS, we are precluded from paying dividends, share repurchases, debt issuances and equity financings.
