energy from the applicable facility may be determined by the energy price (or locational marginal price) at a different node on the transmission system. This is an industry practice used to address the lack of liquidity at individual facility locations. There is a risk, however, that prices at these two nodes differ materially, and as a result of this so called “basis risk,” we may be required to settle our financial hedges at prices that are higher than the prices at which we are able to sell physical power from the applicable facility, thus reducing the effectiveness of the swap hedges.
We are exposed to foreign currency exchange risks because certain of our renewable energy facilities are located outside of the United States.
We generate a portion of our revenues and incur a portion of our expenses in currencies other than U.S. dollars. The portion of our revenues generated in currencies other than U.S. dollars increased substantially upon our acquisition of our European Platform and may also increase in the future if we acquire additional assets outside of the United States. Changes in economic or political conditions in any of the countries in which we operate now or in the future could result in exchange rate movement, expropriation, new currency or exchange controls or other restrictions being imposed on our operations. As our financial results are reported in U.S. dollars, if we generate revenue or earnings in other currencies, the translation of those results into U.S. dollars can result in a significant increase or decrease in the amount of those revenues or earnings. To the extent that we are unable to match revenues received in foreign currencies with costs paid in the same currency, exchange rate fluctuations in any such currency could have a negative impact on our profitability. Our debt service requirements are primarily in U.S. dollars even though a percentage of our cash flow is generated in other foreign currencies and therefore significant changes in the value of such foreign currencies relative to the U.S. dollar could have a material negative impact on our financial condition and our ability to meet interest and principal payments on debts denominated in U.S. dollars. In addition to currency translation risks, we incur currency transaction risks whenever we or one of our facilities enter into a purchase or sales transaction using a currency other than the local currency of the transacting entity.
Given the volatility of exchange rates, there can be no assurance that we will be able to effectively manage our currency transaction and/or translation risks. It is possible that volatility in currency exchange rates will have a material adverse effect on our financial condition or results of operations. We expect to experience economic losses and gains and negative and positive impacts on earnings as a result of foreign currency exchange rate fluctuations, particularly as a result of changes in the value of the Euro, Canadian dollar, British pound sterling and other currencies.
Additionally, although a portion of our revenues and expenses are denominated in foreign currency, any dividends we pay will be denominated in U.S. dollars. The amount of U.S. dollar denominated dividends paid to our holders of our Class A common stock will therefore be exposed to a certain level of currency exchange rate risk. Although we have entered into certain hedging arrangements to help mitigate some of this exchange rate risk, these arrangements may not be sufficient to eliminate the risk. Changes in the foreign exchange rates could have a material negative impact on our results of operations and may adversely affect the amount of cash dividends paid by us to holders of our Class A common stock.
Political instability, changes in government policy, or unfamiliar cultural factors could adversely impact the value of our investments.
We are subject to geopolitical uncertainties in all jurisdictions in which we operate. We make investments in businesses that are based outside of the United States, and we may pursue investments in unfamiliar markets, which may expose us to additional risks not typically associated with investing in the Unites States. We may not properly adjust to the local culture and business practices in such markets, and there is the prospect that we may hire personnel or partner with local persons who might not comply with our culture and ethical business practices; either scenario could result in the failure of our initiatives in new markets and lead to financial losses. There are risks of political instability in several of the jurisdictions in which we conduct business, including, for example, from factors such as political conflict, tariffs, income inequality, refugee migration, terrorism, the potential break-up of political-economic unions (or the departure of a union member, e.g., Brexit) and political corruption. The materialization of one or more of these risks could negatively affect our financial performance. For example, although the long-term impact on economic conditions is uncertain, Brexit may have an adverse effect on the rate of economic growth in the U.K. and continental Europe.
Unforeseen political events in markets where we own and operate assets and may look to for further growth of our businesses may create economic uncertainty that has a negative impact on our financial performance. Such uncertainty could cause disruptions to our businesses, including affecting the business of and/or our relationships with our customers and suppliers, as well as altering the relationship among tariffs and currencies. Disruptions and uncertainties could adversely affect our financial condition, operating results and cash flows. In addition, political outcomes in the market in which we operate may also result in legal uncertainty and potentially divergent national laws and regulation, which can contribute to general economic
