The Partnership did not experience significant disruptions to its business operations in 2020 and does not expect significant disruptions. However, the impact that COVID-19 will have on the Partnership's financial condition, results of operations and cash flows cannot be estimated with certainty at this time as it will depend on future developments, including, among others, the ultimate duration, geographic spread and severity of the virus, the actions to contain the virus, the consequences of governmental and other measures designed to prevent the spread of the virus, the development of effective treatments and vaccines and their roll out, the impact on the operation of OpCo facilities, Westlake, customers, suppliers and other third parties and the timing and extent to which normal economic and operating conditions resume.</span></div>
