liquidity and capital resources we currently expect to fund all of our cash requirements which are reasonably foreseeable for 2018 , including scheduled debt repayments , new investments in the business , share repurchases , dividend payments , possible business acquisitions and pension contributions , with cash from operating activities , and as needed , additional short-term and/or long-term borrowings .
we continue to expect our operating cash flow to remain strong .

the remaining foreign earnings were repatriated in 2016 , reducing the deferred tax liabilities to zero at december 31 , 2016 .

the credit facility supports our $ 2.0 billion u.s .

* interest on variable rate debt was calculated using the interest rate at year-end 2017 .
during the fourth quarter of 2017 , we recorded a one-time transition tax related to enactment of the tax act .
the expense is primarily related to the one-time transition tax , which is payable over eight years .
as discussed further in note 12 , this balance is a provisional amount and is subject to adjustment during the measurement period of up to one year following the enactment of the tax act , as provided by recent sec guidance .
as of december 31 , 2017 , our gross liability for uncertain tax positions was $ 68 million .
we are not able to reasonably estimate the amount by which the liability will increase or decrease over an extended period of time or whether a cash settlement of the liability will be required .
therefore , these amounts have been excluded from the schedule of contractual obligations. .
