Accounts Receivable [Abstract]
Accounts Receivable	11. Accounts Receivable Accounts receivable includes freight and other receivables reduced by an allowance for doubtful accounts. The allowance is based upon historical losses, creditworthiness of customers, and current economic conditions. At December 31, 2019, and December 31, 2018, our accounts receivable were reduced by $4 million and $3 million, respectively. Receivables not expected to be collected in one year and the associated allowances are classified as other assets in our Consolidated Statements of Financial Position. At December 31, 2019, and December 31, 2018, receivables classified as other assets were reduced by allowances of $35 million and $27 million, respectively. Receivables Securitization Facility – On July 29, 2019 the Railroad completed the renewal of the receivables securitization facility (the Receivables Facility). The new $800 million, 3-year facility replaces the prior $650 million facility and will mature in July 2022. Under the Receivables Facility, the Railroad sells most of its eligible third-party receivables to Union Pacific Receivables, Inc. (UPRI), a consolidated, wholly-owned, bankruptcy-remote subsidiary that may subsequently transfer, without recourse, an undivided interest in accounts receivable to investors. The investors have no recourse to the Railroad’s other assets except for customary warranty and indemnity claims. Creditors of the Railroad do not have recourse to the assets of UPRI. The amount recorded under the Receivables Facility was $400 million at both December 31, 2019, and December 31, 2018. The Receivables Facility was supported by $1.3 billion and $1.4 billion of accounts receivable as collateral at December 31, 2019, and December 31, 2018, respectively, which, as a retained interest, is included in accounts receivable, net in our Consolidated Statements of Financial Position. The outstanding amount the Railroad is allowed to maintain under the Receivables Facility, with a maximum of $800 million, may fluctuate based on the availability of eligible receivables and is directly affected by business volumes and credit risks, including receivables payment quality measures such as default and dilution ratios. If default or dilution ratios increase one percent, the allowable outstanding amount under the Receivables Facility would not materially change. The costs of the Receivables Facility include interest, which will vary based on prevailing benchmark and commercial paper rates, program fees paid to participating banks, commercial paper issuance costs, and fees of participating banks for unused commitment availability. The costs of the Receivables Facility are included in interest expense and were $14 million, $15 million, and $6 million for 2019, 2018, and 2017, respectively.
