A novel strain of coronavirus, COVID-19, was first identified in China in December 2019 and became a global pandemic in March 2020. Our businesses may be materially and adversely affected by the ongoing COVID-19 pandemic or the outbreak of other communicable diseases, including epidemics and pandemics.
The COVID-19 pandemic has had, and continues to have, a material impact on businesses around the world, including ours, and the economic and political environments in which businesses operate. There is a number of factors associated with the ongoing COVID-19 pandemic and its impact on global economies that could have a material adverse effect on our business, financial condition, results of operations, cash flows, prospects and the market price of our securities.
A number of countries, states or areas where we operate have implemented policies in response to the COVID-19 pandemic, including declaring states of emergency, implementing severe restrictions on the movement and activities of people and/or implementing restrictions on the operations of certain businesses. These restrictions are determined by the central or local governments of individual jurisdictions (including through the implementation of emergency powers) and impacts (including the timing of implementation and any subsequent lifting of restrictions) may vary from jurisdiction to jurisdiction. Restrictions on the movement of people and on business operations have a significant impact on economic activity in the relevant countries, states or areas and could adversely affect our operational capacity or productivity, could disrupt transportation networks and supply and distribution chains causing disruptions in our businesses operations, and could significantly reduce customer demand or result in unfavorable changes in consumer behavior. In addition, governmental and regulatory actions and support measures taken in response to the COVID-19 outbreak may impose restrictions or obligations on our businesses and may limit management's flexibility in managing our business.
In 2020, particularly between March and July, the COVID-19 pandemic adversely affected our revenue as a result of (i) a decrease in demand for certain of our products, principally reduced demand for fuel as a result of the restrictions imposed by states of Brazil on movement of people and the operation of businesses in many parts of Brazil (which has also prompted us to relax certain contractual clauses with Ipiranga's resellers) and (ii) reduced sales in Extrafarma as a result of the temporary closure of drugstores located in shopping malls in connection with the COVID-19 pandemic.
The dissemination of COVID-19 made us change our business practices (including additional hygienic practices for workplaces and employees, in addition to canceling in-person meetings, events and conferences) during the pandemic. In addition, we also created a crisis committee to identify and monitor the main developments and risks relating to COVID-19 and to adopt preventive and emergency measures to reduce their effects. We may take additional actions, as required by government authorities or as determined by management, considering the best interests of our employees, customers and business partners. We cannot guarantee that these measures will be sufficient to mitigate the risks posed by the pandemic or that they will meet the demands of government authorities.
The COVID-19 pandemic has caused disruption to our customers, suppliers, personnel and resellers in Brazil and in all other countries in which we operate. Nonetheless, pursuant to Federal Decree No. 10,282/20, which was issued in the context of Federal Law No. 13,979/20, the activities of the subsidiaries of Ultrapar are considered essential during the ongoing COVID-19 pandemic. As a result, our subsidiaries have continued to operate and have ensured a continuous supply of their products and services to their clients. However, we cannot assure that our subsidiaries will not be impacted by external factors, such as the limitation of access by our subsidiaries to operational inputs, clients, and financial resources. We also cannot assure that the current legal framework will not be altered. If it happens, all or some of our subsidiaries' activities may no longer be considered essential and might be subject to restrictions that could materially affect the results of our operations and businesses.
In addition, the COVID-19 pandemic has affected business and economic sentiment, causing significant volatility in global markets and affecting the outlook of the economy of Brazil and of the other countries in which we operate. Such affects include significant volatility in the price of crude oil, the price of LPG and the price of other commodities, as well as significant volatility in foreign exchange rates, borrowing costs and the availability of credit. A continuation or worsening of the levels of market disruption and volatility seen in the recent past could have an adverse effect on our ability to access funding and on our ability to negotiate and enter into any amendments that may be required in the future to the terms of our existing indebtedness. The COVID-19 pandemic has led to a weakening in gross domestic product in several countries around the world, including in the countries in which we operate, and the probability of a more adverse economic scenario for at least the short term is substantially higher than the outlook that existed before March 2020.
As noted above, oil prices declined sharply as a result of a significant and rapid decrease in demand for fuels caused by the outbreak of the ongoing COVID-19 pandemic. Brent crude oil prices dropped 34% from US$64 per barrel in the end of December 2019 to US$42 per barrel in the end of December 2020, thus reducing prices of gasoline and diesel worldwide. Gasoline and diesel sales prices in Brazil are directly influenced by international prices and, as such, in 2020 prices of diesel decreased 14% and prices of gasoline decreased 3% in Brazil. In addition, the volatility in the prices of oil and oil products since the end of March, combined with an fall in the price of ethanol in April, caused inventories losses in the second quarter 2020. If our competitors have the ability to access imported diesel and gasoline at a lower cost than our average cost, our competitiveness may be impacted and, consequently, this could adversely affect our results of operations.
In addition to general effects on the economy and the businesses of our suppliers and clients, the COVID-19 pandemic – and any other communicable disease – imposes risks to our operations directly. For instance, if a group of employees of the same division is infected simultaneously, such division may have its activities and businesses affected. If this occurs to a strategic division – or to more than one division simultaneously, it can adversely affect our operation and businesses, and results as a consequence.
New variants and mutations of the virus that causes COVID-19 have been emerging in different countries, including in Brazil, and new waves were spotted in the past months. Events like new waves of mutated coronavirus can add even more uncertainty to the economic scenario, rapidly changing predictions and forecasts. In addition, we cannot predict the potential severity of the economic downturn or recession and we cannot predict the post-crisis recovery environment which, from a commercial, economic, political, regulatory and risk perspective, could be significantly different to past crises and could persist for a prolonged period. The extent to which the COVID-19 outbreak will affect our business, financial condition, results of operations or cash flows will depend on present and future developments, which are highly uncertain and unpredictable. These developments include, among others, the duration and geographic distribution of the outbreak and new waves, its severity, actions to contain the virus or minimize its impact, and how quickly and to what extent normal economic and operational conditions can be resumed. Even after containing the outbreak of COVID-19, our business may continue to suffer adverse and material impacts due to the global or regional economic impact, including recession and economic slowdown, which may affect the purchasing power of our customers.
Also, it remains uncertain to what extent the financial information, after December 31, 2020, may still be affected by the commercial, operational and financial impacts of the pandemic, because it will depend on its duration and the impacts on economic activities, as well as government, and businesses in response to the crisis. In this context, some financial risk assessments, projections and impairment tests, in connection with the preparation of these financial statements, may be impacted by the pandemic, and may adversely affect the financial position of the Company and its subsidiaries. In addition, the increased volatility in financial markets may impact our financial results where a fair value approach is required.
As there are no comparable recent events that can provide us with guidance regarding the effect of a severe global pandemic, we cannot predict the final impact of the COVID-19 outbreak. Finally, the impact of the COVID-19 pandemic can also precipitate or exacerbate the other risks described in this annual report.
