Description: Health insurance company assets and liabilities have evolved since the Patient Protection and Affordable Care Act (ACA) was signed into law in March 2010. The ACA fundamentally rearranged how commercial health insurance is funded by integrating federal premium subsidies and pass-throughs together with a marketplace interwoven with transfer payments among stakeholders. The impacts of these programs can be seen in specific accounting items on the balance sheets of health insurance companies over the past 10 years. Their emergence follows three primary trends: (1) balance sheet items tend to be larger and take longer to settle, (2) there are more interactions among items, and (3) the final settlement amounts are more uncertain.
