We have credit policies in place that are designed to mitigate credit risk associated with wholesale counterparties through a requirement for credit enhancements including, but not limited to, letters of credit, parent guarantees and cash collateral when deemed necessary. For certain counterparties or their guarantors that meet this policy&#8217;s credit worthiness criteria, both Washington Gas and WGEServices grant unsecured credit which is continuously monitored. Additionally, our agreements with wholesale counterparties contain netting provisions which allow the receivable and payable exposure related to each counterparty to be offset.
