A significant portion of our revenue is derived from our international operations, and our success is dependent upon our operations in Mexico and Canada. Our international operations are subject to a variety of risks, including fluctuations in foreign currencies, changes in the economic strength of the foreign countries in which we do business, difficulties in enforcing contractual obligations and intellectual property rights, compliance burdens associated with a wide variety of international and United States export and import laws, and social, political, and economic instability. Our international business could be adversely affected by restrictions on travel to any of our three countries of operations due to a health epidemic or outbreak, and any such epidemic or outbreak may adversely affect demand for freight. Additional risks associated with our foreign operations include restrictive trade policies, imposition of duties, taxes, or government royalties by foreign governments, and compliance with the Foreign Corrupt Practices Act and local anti-bribery law compliance. At present, cross-border movements for both United States and Mexican-based carriers into the United States and Mexico are allowed, which presents a risk in the form of the potential for increased competition in Mexico and the risk of increased congestion on our cross-border lanes. In addition, we could be subject to additional regulatory risks related to the use of Mexican drivers through our Mexico subsidiary for shipments into the United States. Recently, President Donald Trump, certain members of the U.S. House of Representatives, and key U.S. administrative officials and policy makers have suggested the renegotiation of the North American Free Trade Agreement and the implementation of tariffs, border taxes, or other measures that could impact the level of trade between the U.S. and Mexico. Any such proposal or measure could negatively impact certain of our customers and the volume of shipments between the U.S. and Mexico, which could have a materially adverse effect on our business and operating results.
We are also updating the risk factors under the heading "Risks Relating to Quality and its Financing Arrangements" by replacing them with the following:
Our non-controlling investment in 19th Capital, a joint venture, poses unique financial, accounting, and governance risks.
In the first quarter of fiscal 2016, we acquired a minority interest in 19th Capital, a newly formed equipment leasing company and reseller. In the second quarter of fiscal 2017, old equity units were redeemed by 19th Capital and 19th Capital was then recapitalized as a joint venture with Element. As part of this transaction, our existing minority interest was redeemed and we made a new investment in 19th Capital, such that we and Element each own approximately 49.99% of 19th Capital's outstanding equity interests. We account for our investment in 19th Capital using the equity method of accounting. Our participation in the joint venture through our ownership of 19th Capital poses several unique risks that could materially and adversely affect our results of operations and stock price.
As part of the joint venture transaction, our previous obligation to make lease shortfall advance payments to Element was terminated, except with respect to lease shortfall advance payments owed to a particular third party who had been assigned approximately 2.9% of Element's portfolio. Lease shortfall advance payment obligations to this third party were assigned to and assumed by 19th Capital. To the extent we are required to make these payments to the third party, 19th Capital would be obligated to indemnify us. However, any claim we would have against 19th Capital would be unsecured and in a bankruptcy or other insolvency event relating to 19th Capital, our claim would effectively be subordinate to the claims of 19th Capital's secured creditors. In addition, we do not have the ability to unilaterally control 19th Capital and any payment of an indemnity claim by 19th Capital to us could be subject to approval by the board members of 19th Capital appointed by Element. Further, an indemnification claim against 19th Capital could conflict with our interests as an equity holder of 19th Capital. Accordingly, there can be no assurance that 19th Capital will be able to reimburse us for lease shortfall advance obligations if we are required to pay them.
Quality provides lease collection, insurance procurement, vehicle maintenance, and other services to 19th Capital under a Service Agreement. Quality receives certain fees for these services, the primary component of which is a fixed amount per tractor under Quality's management per month. Element is entitled to terminate the Service Agreement without cause upon not less than 90 days' notice to Quality. Moreover, the per-tractor fee is subject to renegotiation by us and Element after the first anniversary of the joint venture's closing. If Element terminates the Service Agreement or we are unable to renegotiate an attractive per-tractor fee, our cash flow, earnings, and other results of operations could be materially and adversely affected.
In addition, while certain of our executive officers serve as two of the managers of 19th Capital, we do not have the ability to unilaterally control 19th Capital's ownership or management. Certain significant decisions must be approved by 19th Capital's board, which currently includes two managers appointed by us and two managers appointed by Element. Our investment in 19th Capital is subject to the risk that 19th Capital's management and Element may seek to make business, financial, or management decisions with which we do not agree or that the management or Element may seek to take risks or otherwise act in a manner that does not serve our interests. Moreover, because we and Element each control 50% of 19th Capital's board, an inability to agree could lead to board deadlock. Element is also a lender to 19th Capital and its interests as a creditor of 19th Capital may not align with ours as an equity holder. For example, in a liquidation of 19th Capital, as a secured creditor Element would generally have priority over us with respect to any assets or other liquidation proceeds, up to the amount of the applicable debt. This difference in rights could cause Element to enforce its rights as creditor, to our detriment as an equity holder. If any of the foregoing were to occur, the value of our investment in 19th Capital could decrease, and our financial condition, results of operations, and cash flow could suffer as a result.
We have recorded the value of our investment in 19th Capital at $100.0 million, based on our net book value of the assets contributed. We may, from time-to-time, be required to revalue our investment in 19th Capital. If we are required to mark down the recorded value of our investment, whether due to poor performance of 19th Capital or otherwise, our results of operations, earnings, and stock price could be materially and adversely affected.
If a change in accounting rules or other unforeseen circumstances prevents us from using our intended accounting treatment for 19th Capital, we may be required to include the related equipment debt on our consolidated balance sheet even though we are not primarily obligated on and do not guarantee such debt. This could cause us to violate financial covenants under our primary credit facility or otherwise materially and adversely affect our results of operations and stock price.
Finally, under the equity method of accounting, we anticipate that we will recognize our proportionate share of 19th Capital's income or loss in any given period. As a result, poor performance of 19th Capital would have a negative impact on our results of operations. See "19th Capital faces certain additional risks particular to its operations, any one of which could adversely affect our operating results" for additional information on risks faced by 19th Capital that could have a material adverse impact on us.
