* 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. .
