Item 1A. Risk Factors

Risk Factors — what could go wrong, per management

62 edited+23 added9 removed224 unchanged
Biggest changeThe impact and effects of public health crises, pandemics and epidemics, including the ongoing coronavirus (COVID-19) pandemic, could materially adversely affect Westlake's business, financial condition and results of operations. OpCo is a restricted subsidiary under certain indentures governing Westlake's senior notes. The ethylene sales price charged under the Ethylene Sales Agreement is designed to permit OpCo to cover the substantial majority of its operating costs, but not our public partnership and other OpCo costs, which reduce our net operating profit. If OpCo is unable to renew or extend the Ethylene Sales Agreement beyond the initial 12-year term or the other agreements with Westlake upon expiration of these agreements, our ability to make distributions in the future could be materially adversely affected and the value of our units could decline. OpCo has the right to use the real property underlying Lake Charles Olefins and Calvert City Olefins pursuant to two, 50-year site lease agreements with Westlake.
Biggest changeIf Westlake does not pay us under the terms of the Ethylene Sales Agreement or if our assets fail to perform as intended, we may not have sufficient cash from operations following the establishment of cash reserves and payment of costs and expenses, including cost reimbursements to our general partner and its affiliates, to enable us to pay the minimum quarterly distribution to our unitholders. OpCo is subject to the credit risk of Westlake on a substantial majority of its revenues, and Westlake's leverage and creditworthiness could adversely affect our ability to make distributions to our unitholders.
