Notes to Financial Statements
Loans, Notes, Trade and Other Receivables Disclosure [Text Block]	8. Accounts Receivable Accounts receivable includes freight and other receivables reduced by an allowance for doubtful accounts. At both March 31, 2023, and December 31, 2022, our accounts receivables were reduced $10 million. Receivables not expected to be collected in one year and the associated allowances are classified as other assets in our Condensed Consolidated Statements of Financial Position. At March 31, 2023, and December 31, 2022, receivables classified as other assets were reduced by allowances of $60 million and $58 million, respectively. Receivables Securitization Facility – The Railroad maintains an $800 million, 3-year receivables securitization facility (the Receivables Facility) maturing in July 2025. 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 $0 and $100 million at March 31, 2023, and December 31, 2022, respectively. The Receivables Facility was supported by $1.6 billion of accounts receivable as collateral at both March 31, 2023 and December 31, 2022, which, as a retained interest, is included in accounts receivable, net in our Condensed Consolidated Statements of Financial Position. The outstanding amount the Railroad maintains under the Receivables Facility may fluctuate based on current cash needs. The maximum allowed under the Receivables Facility is $800 million with availability directly impacted by eligible receivables, 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 $3 million and $1 million for the three months ended March 31, 2023 and 2022 , respectively.
