Short-Term Borrowings and Borrowing Arrangements	Short-Term Borrowings and Borrowing Arrangements At December 31, 2018, Altria had $12.7 billion of short-term borrowings, which is net of $96 million of debt issuance costs, resulting from the Term Loan Agreement discussed below. At December 31, 2017, Altria had no short-term borrowings. On December 20, 2018, Altria entered into the Term Loan Agreement in connection with its investments in JUUL and Cronos. The Term Loan Agreement provides for borrowings up to an aggregate principal amount of $14.6 billion and is comprised of: (i) a $12.8 billion tranche, which Altria used to finance the JUUL Transaction, and (ii) a $1.8 billion tranche, which Altria intends to use to finance its investment in Cronos. Borrowings under the Term Loan Agreement mature on December 19, 2019, and interest rates on borrowings are, and expect to be, based on the London Interbank Offered Rate (“LIBOR”) plus a percentage based on the higher of the ratings of Altria’s long-term senior unsecured debt from Moody’s Investors Service, Inc. (“Moody’s”) and Standard & Poor’s Ratings Services (“Standard & Poor’s”). The applicable percentage based on Altria’s long-term senior unsecured debt ratings at December 31, 2018 for borrowings under the Term Loan Agreement was 1.0%. In addition, the Term Loan Agreement includes a one-time duration fee of 0.125% on any advances outstanding 180 days from December 20, 2018. At December 31, 2018, Altria had aggregate borrowings under the Term Loan Agreement of $12.8 billion at an interest rate of approximately 3.5%. Altria’s estimate of the fair value of its short-term borrowings is derived from discounted future cash flows based on the contractual terms of the Term Loan Agreement and observable interest rates and is classified in Level 2 of the fair value hierarchy. The fair value of Altria’s short-term borrowings at December 31, 2018 approximated its carrying value. At December 31, 2018, accrued interest on short-term borrowings of $15 million was included in other accrued liabilities on Altria’s consolidated balance sheet. On August 1, 2018, Altria entered into a senior unsecured 5-year revolving credit agreement, which was subsequently amended on January 25, 2019 to include certain covenants that become effective upon the completion of Altria’s pending investment in Cronos (as amended, the “Credit Agreement”). The Credit Agreement, which is used for general corporate purposes, provides for borrowings up to an aggregate principal amount of $3.0 billion. The Credit Agreement expires on August 1, 2023 and includes an option, subject to certain conditions, for Altria to extend the Credit Agreement for two additional one-year periods. The Credit Agreement replaced Altria’s prior $3.0 billion senior unsecured 5-year revolving credit agreement, which was to expire on August 19, 2020 and was terminated effective August 1, 2018. Pricing for interest and fees under the Credit Agreement may be modified in the event of a change in the rating of Altria’s long-term senior unsecured debt. Interest rates on borrowings under the Credit Agreement are expected to be based on LIBOR plus a percentage based on the higher of the ratings of Altria’s long-term senior unsecured debt from Moody’s and Standard & Poor’s. The applicable percentage based on Altria’s long-term senior unsecured debt ratings at December 31, 2018 for borrowings under the Credit Agreement was 1.0%. The Credit Agreement does not include any other rating triggers, or any provisions that could require the posting of collateral. At December 31, 2018 and 2017, Altria had no borrowings under the Credit Agreement. The credit line available to Altria at December 31, 2018 under the Credit Agreement was $3.0 billion. The Term Loan Agreement and the Credit Agreement (collectively, the “Borrowing Agreements”) include various covenants, one of which requires Altria to maintain a ratio of consolidated earnings before interest, taxes, depreciation and amortization (“EBITDA”) to Consolidated Interest Expense of not less than 4.0 to 1.0, calculated as of the end of the applicable quarter on a rolling four quarters basis. At December 31, 2018, the ratio of consolidated EBITDA to Consolidated Interest Expense, calculated in accordance with the Borrowing Agreements, was 14.4 to 1.0. At December 31, 2018, Altria was in compliance with its covenants associated with the Borrowing Agreements. The terms “Consolidated EBITDA” and “Consolidated Interest Expense,” each as defined in the Borrowing Agreements, include certain adjustments. Any commercial paper issued by Altria and borrowings under the Borrowing Agreements are guaranteed by PM USA as further discussed in Note 20. Condensed Consolidating Financial Information. At December 31, 2018, Altria had a working capital deficit that included approximately $13.9 billion of debt coming due by December 31, 2019. In addition, Altria has an additional $1.0 billion of debt coming due by January 31, 2020. Although Altria does not currently have the liquid funds necessary to repay all of the $14.9 billion of debt coming due by January 31, 2020, Altria expects to access the credit and capital markets to refinance the debt prior to maturity. Altria believes it is probable that it will implement its refinancing plan because of its profitability, its credit rating, which continues to be investment grade, and history of obtaining financing on reasonable commercial terms.
