Texas Ratio, left axis (lower is healthier)MBR Star Rating, right axis (1 to 5)Health Grade

How to read this chart: the two lines move in opposite directions by design. The Texas Ratio (blue) measures trouble, so a rising blue line means more non-performing assets against capital. The Star Rating (green) and Health Grade chips measure strength, so they fall when the Texas Ratio climbs and recover when it drops.
