What the Form 5500 Data Shows for Connecticut

Leading sector by assets: Manufacturing (44%).

Rtx Savings Plan accounts for 17.9% of all Connecticut retirement plan assets

That concentration means Connecticut-wide averages can mask substantial variation outside the dominant entity. Rtx Corporation sponsors the filing; drill into the plan page for schedules and audit detail. When one entity dominates a region's footprint, its programmatic and budget decisions effectively set policy for a majority of participants counted in this state total.
