The Company enters into contracts to purchase tobacco from farmers in a number of the countries where it operates. Contracts in most countries cover one annual growing season. Primarily with the farmer contracts in Brazil, Malawi, Mozambique, the Philippines, Guatemala, and Mexico, the Company provides seasonal financing to support the farmers’ production of their crops or guarantees their financing from third-party banks. At March 31, 2019, the Company had contracts to purchase approximately $497 million of tobacco to be delivered during the coming fiscal year and $128 million of tobacco to be delivered in subsequent years. These amounts are estimates since actual quantities purchased will depend on crop yields, and prices will depend on the quality of the tobacco delivered and other market factors. Tobacco purchase obligations have been partially funded by short-term advances to farmers and other suppliers, which totaled approximately $107 million, net of allowances, at March 31, 2019. The Company withholds payments due to farmers on delivery of the tobacco to satisfy repayment of the financing it provided to the farmers. As noted above and discussed in more detail below, the Company also has arrangements to guarantee bank loans to farmers in Brazil, and payments are also withheld on delivery of tobacco to satisfy repayment of those loans. In addition to its contractual obligations to purchase tobacco, the Company had commitments related to agricultural materials, approved capital expenditures, and various other requirements that approximated $61 million at March 31, 2019.

Guarantees of bank loans to growers for crop financing have long been industry practice in Brazil and support the farmers’ production of tobacco there. The Company's operating subsidiary in Brazil had guarantees outstanding at March 31, 2019, all of which expire within one year. As noted above, the subsidiary withholds payments due to the farmers on delivery of tobacco and forwards those payments to the third-party banks. Failure of farmers to deliver sufficient quantities of tobacco to the subsidiary to cover their obligations to the third-party banks could result in a liability for the subsidiary under the related guarantees; however, in that case, the subsidiary would have recourse against the farmers. The maximum potential amount of future payments that the Company’s subsidiary could be required to make at March 31, 2019, was the face amount, $17 million including unpaid accrued interest ($20 million as of March 31, 2018). The fair value of the guarantees was a liability of approximately $1 million at March 31, 2019 ($1 million at March 31, 2018). In addition to these guarantees, the Company has other contingent liabilities totaling approximately $2 million at March 31, 2019, primarily under outstanding letters of credit.

As discussed in Note 1, the Company's local operating subsidiaries pay significant amounts of value-added tax ("VAT") in connection with their normal operations. In Brazil, VAT is assessed at the state level when green tobacco is transferred between states. The Company's operating subsidiary there pays VAT when tobaccos grown in the states of Santa Catarina and Parana are transferred to its factory in the state of Rio Grande do Sul for processing. The subsidiary has received assessments for additional VAT plus interest and penalties from the tax authorities for the states of Santa Catarina and Parana based on audits of the subsidiary's VAT filings for specified periods. In June 2011, tax authorities for the state of Santa Catarina issued assessments for tax, interest, and penalties for periods from 2006 through 2009 totaling approximately $12 million. In September 2014, tax authorities for the state of Parana issued an assessment for tax, interest, and penalties for periods from 2009 through 2014 totaling approximately $14 million. These amounts are based on the exchange rate for the Brazilian currency at March 31, 2019. Management of the operating subsidiary and outside counsel believe that errors were made by the tax authorities for both states in determining all or significant portions of these assessments and that various defenses support the subsidiary's positions.

With respect to the Santa Catarina assessments, the subsidiary took appropriate steps to contest the full amount of the claims. As of March 31, 2019, a portion of the subsidiary's arguments had been accepted, and the outstanding assessment had been reduced, although interest on the remaining assessment has continued to accumulate. The reduced assessment, together with the related accumulated interest through the end of the current reporting period, totaled approximately $12 million at the March 31, 2019 exchange rate. The subsidiary is continuing to contest the full remaining amount of the assessment. While the range of reasonably possible loss is zero up to the full $12 million remaining assessment, based on the strength of the subsidiary's defenses, no loss within that range is considered probable at this time and no liability has been recorded at March 31, 2019.

With respect to the Parana assessment, management of the subsidiary and outside counsel challenged the full amount of the claim. A significant portion of the Parana assessment was based on positions taken by the tax authorities that management and outside counsel believe deviate significantly from the underlying statutes and relevant case law. In addition, under the law, the subsidiary's tax filings for certain periods covered in the assessment were no longer open to any challenge by the tax authorities. In December 2015, the Parana tax authorities withdrew the initial claim and subsequently issued a new assessment covering the same tax periods. The new assessment totaled approximately $6 million at the March 31, 2019 exchange rate, reflecting a substantial reduction from the original $14 million assessment. Notwithstanding the reduction, management and outside counsel continue to

believe that the new assessment is not supported by the underlying statutes and relevant case law and have challenged the full amount of the claim. The range of reasonably possible loss is considered to be zero up to the full $6 million assessment. However, based on the strength of the subsidiary's defenses, no loss within that range is considered probable at this time and no liability has been recorded at March 31, 2019.

In both states, the process for reaching a final resolution to the assessments is expected to be lengthy, and management is not currently able to predict when either case will be concluded. Should the subsidiary ultimately be required to pay any tax, interest, or penalties in either case, the portion paid for tax would generate value-added tax credits that the subsidiary may be able to recover.

In June 2012, the Company’s Tanzanian subsidiary, Tanzania Leaf Tobacco Company Ltd. (“TLTC”), entered into a two crop-year supply agreement for unprocessed “green” tobacco with a newly-formed Tanzanian subsidiary of one of the Company’s major customers. The agreement involved green tobacco purchases from four of the approximately 400 grower cooperatives in Tanzania, which allowed the customer and its Tanzanian subsidiary on a small test basis to evaluate whether it would be a viable alternative for the customer to establish its own vertically integrated supply operations in that market. Prior to that time, the customer’s subsidiary did not exist, and it only purchased processed Tanzanian tobacco from tobacco dealers in specified amounts and only for certain grades and stalk positions. In contrast, the agreement with TLTC required the customer’s subsidiary to purchase green tobacco on a “run of crop” basis. “Run of crop” requires the purchase of all green tobacco produced on the tobacco plant, regardless of grade or stalk position. The agreement, therefore, enabled the customer’s subsidiary on a small test basis to evaluate the quality of green tobacco purchased on a “run of crop” basis and to assess how such tobacco would be suited to the customer's tobacco requirements. The customer unilaterally elected to establish its own vertically integrated supply operations in Tanzania after the expiration of the agreement, and its subsidiary began purchasing green tobacco directly from Tanzanian grower cooperatives during the second crop year thereafter.

Despite the pro-competitive object and effect of the agreement between TLTC and the customer’s subsidiary, in October 2016, the Tanzania Fair Competition Commission (“FCC”) notified TLTC and the customer’s subsidiary that it reviewed the agreement and provisionally concluded that it infringed Tanzania antitrust law by having the object and effect of preventing competition in the purchase of unprocessed green tobacco in the area in which the four grower cooperatives were located. The FCC also provisionally concluded that the Company’s U.S. subsidiary, Universal Leaf Tobacco Company, Inc. (“ULT”), and additional subsidiaries of the customer, were jointly and severally liable for the actions of TLTC and the customer’s Tanzanian subsidiary, respectively. TLTC and ULT submitted a written response contesting the FCC’s allegations, and on February 27, 2018, the FCC issued its decision to TLTC and ULT which ignored TLTC's and ULT's submissions and confirmed its initial conclusion that the agreement infringed Tanzanian antitrust law. In its decision, the FCC concluded incorrectly that the parties to the agreement unfairly benefited in the amount of $105 thousand. The FCC arbitrarily assessed a fine jointly against TLTC and ULT of approximately $197 million and a fine jointly against the customer’s Tanzanian subsidiary and another subsidiary of the customer exceeding $1 billion.

TLTC and ULT have worked closely with expert legal advisors and economists on this matter. Based on these engagements and consultations, the Company firmly believes the FCC’s allegations are frivolous and clearly without merit or support from the facts, law or economic analysis. The Company further believes the FCC’s proceedings were rife with irregularities and did not comply with applicable legal and regulatory procedures with respect to this matter, including failing to establish jurisdiction over ULT or to offer a legal justification for including ULT in the proceeding. To the contrary, the Company believes the facts, law and economic analysis clearly support the legality and pro-competitive nature of the agreement and support a proper conclusion that there was no infringement of Tanzania antitrust law, and the agreement had no negative impact on the Tanzania tobacco market. The Company further believes the FCC’s proposed fine is ludicrous, unwarranted and contrary to Tanzania law. TLTC and ULT immediately appealed the FCC findings to the Tanzania Fair Competition Tribunal, which immediately stayed the execution of any FCC fines. The Company is unable to predict how long the appeal process will take; however, the Company believes it could last several years. At this time, the Company believes that the likelihood of incurring any material liability in this matter is remote, and no amount has been recorded.

On January 22, 2019, the FCC delivered provisional findings regarding two new allegations of antitrust violations. In those two new provisional findings, the FCC has manufactured claims against ULT and ULT's subsidiaries in Tanzania, in addition to other parties in Tanzania. ULT and its Tanzania subsidiaries have already begun working closely with expert legal advisors on these matters and will prepare and submit to the FCC proper and comprehensive responses. Although the new provisional findings have only recently been received, based on the legal consultations to date the Company firmly believes the FCC's new allegations are frivolous and clearly without merit and lack facts, law or economic analysis to support them. In one of the two new matters, based on the Company's review of the provisional findings and consultation with counsel, the Company believes the FCC is seeking an equally large, ludicrous, unwarranted, and unlawful fine as the one sought in the current matter. The FCC's motivations for initiating these additional, spurious allegations against the Company's subsidiaries are unclear. At this time, the Company is unable to predict how

long it will take to defend against the new matters including, if necessary, to appeal any final FCC decisions; however, the Company believes it could last several years. At this time, the Company believes that the likelihood of incurring any material liability in the new matters is remote, and no amount has been recorded for either one.

Various subsidiaries of the Company are involved in other litigation and tax examinations incidental to their business activities. While the outcome of these matters cannot be predicted with certainty, management is vigorously defending the matters and does not currently expect that any of them will have a material adverse effect on the Company’s business or financial position. However, should one or more of these matters be resolved in a manner adverse to management’s current expectation, the effect on the Company’s results of operations for a particular fiscal reporting period could be material.

A material part of the Company’s business is dependent upon a few customers. The Company's six largest customers are Altria Group, Inc, British American Tobacco plc, China Tobacco International, Inc., Imperial Brands plc, Japan Tobacco, Inc., and Philip Morris International, Inc. In the aggregate, these customers have accounted for approximately 70% of consolidated revenue for each of the past three fiscal years. For the fiscal years ended March 31, 2019, 2018, and 2017, revenue from Philip Morris International, Inc. was approximately $650 million, $520 million, and $590 million, respectively. For the same periods, Imperial Brands plc accounted for revenue of approximately $360 million, $270 million, and $230 million, respectively, and British American Tobacco plc accounted for revenue of approximately $270 million, $230 million, and $220 million, respectively. These customers primarily do business with various affiliates in the Company’s flue-cured and burley leaf tobacco operations. The loss of, or substantial reduction in business from, any of these customers could have a material adverse effect on the Company.

The Company’s operating subsidiaries perform credit evaluations of customers’ financial condition prior to the extension of credit. Generally, accounts receivable are unsecured and are due within 30 days. When collection terms are extended for longer periods, interest and carrying costs are usually recovered. Credit losses are provided for in the financial statements, and historically such amounts have not been material. The allowance for doubtful accounts was approximately $3 million and $2 million at March 31, 2019 and 2018, respectively. At March 31, 2019 and 2018, net accounts receivable by reportable operating segment were as follows:
