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.
