[['( millions )', 'total', 'payments due by period less than 1 year', 'payments due by period 2-3 years', 'payments due by period 4-5 years', 'payments due by period more than 5 years'], ['notes payable', '$ 15', '$ 15', '$ -', '$ -', '$ -'], ['one-time transition tax', '160', '13', '26', '26', '95'], ['long-term debt', '7303', '549', '696', '1513', '4545'], ['capital lease obligations', '5', '1', '1', '1', '2'], ['operating leases', '617', '131', '211', '160', '115'], ['interest*', '2753', '242', '436', '375', '1700'], ['total', '$ 10853', '$ 951', '$ 1370', '$ 2075', '$ 6457']]
* 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. .
