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. Show the quarterly figures
