In response to the outbreak, many countries, ports and organizations, including those where the Company conducts a large part of its operations, have implemented measures to combat the outbreak, such as quarantines and travel restrictions. These measures have resulted in a significant reduction in global economic activity and extreme volatility in the global financial markets. There continues to be a high level of uncertainty relating to how the pandemic will evolve, including the availability of vaccines and their global deployment, the development of effective treatments, the imposition of effective public safety and other protective measures and the public's and government's responses to such measures. At present, it is not possible to ascertain any future impact of Covid-19 on the Company’s operational and financial performance, which may take some time to materialize and may not be fully reflected in the Company’s results for 2020 and 2021. However, an increase in the severity or duration or a resurgence of the Covid-19 pandemic and the timing of wide-scale vaccine distribution could have a material adverse effect on the Company’s business, results of operations, cash flows, financial condition, the carrying value of the Company’s assets, the fair values of the Company’s vessels, and the Company’s ability to pay dividends. As of June 30, 2021, the Company owned a modern fleet of 128 dry bulk vessels consisting of Newcastlemax, Capesize, Post Panamax, Kamsarmax, Panamax, Ultramax and Supramax vessels with a carrying capacity between 52,000 deadweight tonnage (“dwt”) and 210,000 dwt, a combined carrying capacity of 14.1 million dwt and an average age of 9.4 years.
