pre_text: we may not be able to generate sufficient cash to service all of our indebtedness and may be forced to take other actions to satisfy our obligations under our indebtedness , which may not be successful .
our ability to make scheduled payments on or to refinance our debt obligations depends on our financial condition , operating performance and our ability to receive dividend payments from our subsidiaries , which is subject to prevailing economic and competitive conditions , regulatory approval and certain financial , business and other factors beyond our control .
we may not be able to maintain a level of cash flows from operating activities sufficient to permit us to pay the principal and interest on our indebtedness .
if our cash flows and capital resources are insufficient to fund our debt service obligations , we may be forced to reduce or delay investments and capital expenditures , or to sell assets , seek additional capital or restructure or refinance our indebtedness .
these alternative measures may not be successful and may not permit us to meet our scheduled debt service obligations .
in addition , the terms of existing or future debt instruments may restrict us from adopting some of these alternatives .
our ability to restructure or refinance our debt will depend on the condition of the capital markets and our financial condition at such time .
any refinancing of our debt could be at higher interest rates and may require us to comply with more onerous covenants , which could further restrict our business operations .
in addition , any failure to make payments of interest and principal on our outstanding indebtedness on a timely basis would likely result in a reduction of our credit rating , which could harm our ability to incur additional indebtedness .
if our cash flows and available cash are insufficient to meet our debt service obligations , we could face substantial liquidity problems and might be required to dispose of material assets or operations to meet our debt service and other obligations .
we may not be able to consummate those dispositions or to obtain the proceeds that we could realize from them , and these proceeds may not be adequate to meet any debt service obligations then due .
