        <ExplanationTxt>SPP executives and management level personnel periodically use private plans or charter travel for business purposes. Occasionally, Nicholas Brown (CEO and President) is accompanied by his spouse when traveling for business purposes. The costs related to this travel are paid by Southwest Power Pool. SPP has a travel and expense reimbursement policy in place to govern expenses incurred by employees for the benefit of the company. Also, all employees of the organization who are eligible to receive benefits are provided an insurance credit which is grossed-up for payroll purposes and reported as taxable compensation. There's no specific policy that governs the insurance gross-up payments, however it's a company-wide practice.</ExplanationTxt>
