Net assets (after liabilities) closed the year at $55M, with reported net income of $3M driven by investment returns, contributions received, and benefit payments during the period. These figures reflect what the plan administrator certified on Schedule H or Schedule I of the Form 5500 annual return and can be compared against 2 prior plan-year filings from the same sponsor shown below.

Asset totals and participant counts reflect a single plan year snapshot and can change materially with market conditions, plan mergers, or workforce changes. Fields such as "net income" include both realized investment performance and contribution/distribution flows — a single-year figure does not by itself indicate plan health or participant outcomes.
