PGE sponsors a health and welfare plan, under which it offers medical and life insurance benefits, as well as health reimbursement arrangements (HRAs). Retirees who participate in the Company’s postretirement health insurance plans are eligible for a Defined Dollar Medical Benefit (DDB), which limits PGE’s obligation pursuant to the postretirement health plan by establishing a maximum benefit per employee with employees responsible for the additional cost. In the third quarter of 2019, PGE announced an amendment to its HRAs and DDBs for non-represented employees, resulting in a $2 million curtailment gain, which has been recorded in Miscellaneous income, net on the condensed consolidated statement of income and comprehensive income.
