working capital purposes, including potentially for the repurchase, redemption or retirement of outstanding debt or equity securities.
The liquidity of our Parent Company is dependent on our Operating Partnership’s ability to make sufficient distributions to our Parent Company. The primary cash requirement of our Parent Company is its payment of dividends to its stockholders. Our Parent Company also guarantees our Operating Partnership’s, as well as certain of its subsidiaries’ and affiliates’, unsecured debt. If our Operating Partnership or such subsidiaries fail to fulfill their debt requirements, which trigger Parent Company guarantee obligations, then our Parent Company will be required to fulfill its cash payment commitments under such guarantees. However, our Parent Company’s only material asset is its investment in our Operating Partnership.
We believe our Operating Partnership’s sources of working capital, specifically its cash flow from operations, and funds available under its global revolving credit facility are adequate for it to make its distribution payments to our Parent Company and, in turn, for our Parent Company to make its dividend payments to its stockholders. However, we cannot assure you that our Operating Partnership’s sources of capital will continue to be available at all or in amounts sufficient to meet its needs, including making distribution payments to our Parent Company. The lack of availability of capital could adversely affect our Operating Partnership’s ability to pay its distributions to our Parent Company, which would in turn, adversely affect our Parent Company’s ability to pay cash dividends to its stockholders.
