Periods of market volatility have occurred and could continue to occur in response to pandemics or other events outside of our control. These types of events have adversely affected, and could continue to adversely affect, operating results for us and for our portfolio companies. The COVID-19 pandemic had a significant adverse effect on the U.S. economy, particularly in the second quarter of 2020. Although certain economic conditions in the United States improved in 2021, the pandemic continues to evolve, as recently experienced with the rapid spread of the Omicron variant, and risks remain with respect to local, regional, national and global markets and economies affected thereby, including the United States. With respect to U.S. and global credit markets and the economy in general, the pandemic has resulted in, and until fully resolved is likely to continue to result in, the following (among other things): (i) restrictions on travel and the temporary closure of many corporate offices, retail stores and manufacturing facilities and factories, resulting in significant disruption to the business of many companies, including supply chains and demand, as well as layoffs of employees; (ii) increased draws by borrowers on revolving lines of credit; (iii) increased requests by borrowers for amendments or waivers of their credit agreements to avoid default, increased defaults by borrowers and/or increased difficulty in obtaining refinancing; (iv) volatility in credit markets, including greater volatility in pricing and spreads; and (v) evolving proposals and actions by state and federal governments to address the problems being experienced by markets, businesses and the economy in general, which may not adequately address the problems being faced. The COVID-19 pandemic is continuing as of the filing date of this Annual Report, and its extended duration may have further adverse impacts on our portfolio companies after December 31, 2021, as well as the economy in general.
This pandemic has also caused, and may continue to cause, disruption to our portfolio companies' global supply chain and business operations. In particular, shortages in commodities and materials, including shortages and reductions in allocations of electronic and other components from key suppliers, labor shortages and elevated levels of employee absenteeism, freight delays and other supply chain constraints and disruptions have significantly delayed or disrupted, and may continue to adversely impact, both our portfolio companies' suppliers' and third-party vendors and our portfolio companies' ability to manufacture and deliver products and/or services to their end-users and customers. Our portfolio companies have also experienced a significant increase in commodity, parts and material component inflation in 2021 and 2022, as well as inflation in other costs, such as labor, packaging, freight and energy prices. Continued supply chain disruptions and delays, as well as continued heightened inflation, could lead to continued periodic production interruptions and other inefficiencies that could negatively impact our portfolio companies' productivity, margin performance and results of operations, which could result in a material adverse effect on our financial condition, results of operations and cash flows.
Although it is impossible to predict the precise nature and consequences of these events, or of any political or policy decisions and regulatory changes occasioned by emerging events or uncertainty on applicable laws or regulations that impact us and our portfolio companies and investments, it is clear that these types of events are impacting and will, for at least some time, continue to impact us and our portfolio companies; in many instances the impact will be adverse and material. Any potential impact to our results of operations will depend to a large extent on future developments and the ultimate duration and severity of the COVID-19 pandemic and the actions taken by authorities and other entities to contain the spread or treat its impact, all of which are beyond our control. These potential impacts, while uncertain, could adversely affect our and our portfolio companies' operating results and financial condition.
The COVID-19 pandemic and the related disruption and financial distress experienced by our portfolio companies may have material adverse effects on our financial results, including investment income received from our investments and the underlying value of those investments. The COVID-19 pandemic has adversely impacted the fair value of certain of our investments, including those reported as of December 31, 2021, and the values reported may differ materially from the values that we may ultimately realize with respect to our investments. We may need to restructure our investments in certain portfolio companies as a result of the adverse effects of the COVID-19 pandemic, which could reduce the amount or extend the time for payment of principal or the life of our investment or reduce the amount or extend the time of payment of interest or dividends, among other things. Depending on the duration of the COVID-19 pandemic and the extent of its continuing effects on our portfolio companies' operations and our operating results, any future dividends to our stockholders may be for amounts less than our historical dividends, may be paid less frequently than historical practices and may also include return of capital.
The 1940 Act generally prohibits us, as a BDC, from incurring indebtedness unless immediately after such borrowing we have an asset coverage, as defined in the 1940 Act, of at least 200% (or 150% if certain requirements are met). In addition, the terms of our senior securities may contain similar limitations or covenants requiring our compliance with the 1940 Act asset coverage requirements, and other affirmative and negative covenants. A continued significant decrease in the value of our Investment Portfolio, due to the effects of the COVID-19 pandemic or otherwise, resulting in significant reductions of our net asset value increases the risk of us not meeting the required asset coverage requirement under the 1940 Act or breaching covenants under our senior securities. Any such result could have a material adverse effect on our business, liquidity, financial condition, results of operations and ability to pay dividends to our stockholders and attributes thereof.
