A novel strain of coronavirus (Covid-19) was first identified in Wuhan, China in late 2019, and, in March 2020, was declared a pandemic by the World Health Organization. This public health crisis precipitated by the pandemic, which subsequently spread globally, as well as measures taken by national governments, other regulatory bodies and businesses in response to the pandemic, have caused and are continuing to cause business slowdowns or shutdowns in affected areas, as well as general economic instability and disruption to Diageo's operations. At this time, there is still some uncertainty as to the longer-term impact of the Covid-19 pandemic on Diageo's business and operations and it is possible that the future impact will be greater than expected if, for example, vaccination rollouts are slower than expected or if other preventative measures become less effective (including against any new variants of Covid-19 that are identified). To date, the direct impacts on Diageo's business from the Covid-19 pandemic have included, but are not limited to: –the closure of and/or other restrictions being placed upon on-trade channels such as bars, restaurants and other hospitality venues in a significant number of Diageo's markets globally (including, in particular, in Europe and Turkey) as a result of government social distancing mandates and/or other factors, which have impacted the volume of Diageo's products sold via those channels (including Guinness, which has been significantly impacted by on-trade closures in the UK and Ireland) and which, in the longer-term, may lead to shifts in consumer behaviour and purchasing patterns; –temporary disruptions to Diageo's ability to operate certain of its production and other facilities due to regulatory restrictions or other factors, as well as the implementation of heightened safety protocols in all of Diageo's facilities and offices worldwide leading to restrictions to access, reductions in activity levels, employees of Diageo and its suppliers and distributors not being able to work at all or work as efficiently due to home working, illness, quarantines or other factors, as well as other additional costs; –wider disruptions to Diageo's supply chains and/or those of its suppliers, distributors and/or customers; and –the imposition of travel restrictions by numerous jurisdictions combined with public concern about travel resulting in significant declines in passenger numbers, particularly for air travel, leading to a substantial reduction in net sales in Diageo's Travel Retail business. The impacts of the Covid-19 pandemic and related response measures worldwide, including the impacts described above, have had and may continue to have an adverse effect on global economic conditions, as well as on Diageo’s business, results of operations, cash flows and financial condition, with recovery expected to be dependent on the success of public health measures, the impact of economic policies, and how quickly consumers choose to return to bars, restaurants and other hospitality venues, as well as resume international travel. However, even those regions that are beginning to experience business recovery or the scaling back of response measures, such as the United States and Europe, may experience further impacts from Covid-19 (including from any new variants of the Covid-19 virus that emerge), and economic activity in those regions may not recover quickly or at all, which could materially adversely impact global economic conditions. This could in turn lead to a further decline in discretionary spending by consumers. In addition, a global outbreak of another novel public health threat, or fear of such an event, could result in a resurgence of government restrictions and regulations and result in any of the impacts described above. Diageo conducts impairment reviews as and when required in accordance with applicable accounting standards, to ensure that, among other things, intangible assets, including brands, are not carried at above their recoverable amounts. The impacts of the Covid-19 pandemic and related response measures, in particular with respect to expectations of future cash flows, contributed to approximately £1.3 billion in impairments recognised by the Diageo group during its fiscal year ended 30 June 2020, primarily impacting assets located in India, Korea, Nigeria and Ethiopia where, in some cases, already challenging economic conditions and/or other factors were exacerbated by the Covid-19 pandemic. Although there were no further material write-downs during the fiscal year ended 30 June 2021, further material write-downs or impairments may need to be recognised during future periods due to potential continuing impacts from the Covid-19 pandemic. In addition, the impact of the Covid-19 pandemic on global economic conditions has impacted and may continue to impact the proper functioning of financial and capital markets, as well as foreign currency exchange rates, commodity and energy prices and interest rates. Responses to the Covid-19 pandemic may also result in both short-term and long-term changes to fiscal and tax policies in impacted jurisdictions, including increases in tax rates. Although Diageo completed bond issuances under both its European and US shelf programmes during 2020 and may take other actions to enhance its liquidity, there is no guarantee that Diageo’s existing arrangements or any future arrangements will provide sufficient liquidity over the course of the Covid-19 pandemic, and the impacts of the Covid-19 pandemic and related response measures may adversely impact Diageo’s liquidity or financial position. In addition, a continuation or worsening of the levels of market disruption and volatility seen in the recent past, either as a result of the Covid-19 pandemic or of the emergence of any other new international public health threat, could have an adverse effect on Diageo’s ability to access, or costs of, capital or borrowings, its liquidity, its financial position, its adjusted net debt to EBITDA ratio, its ability to comply with any applicable financial covenants or its credit ratings. Any of the foregoing developments may have a material adverse effect on Diageo’s business, financial condition, cash flows and results of operations. In addition, the impact of the Covid-19 pandemic, or any other future epidemics or pandemics, may also have the effect of heightening many of the risks described elsewhere within this annual report.
