The document contains two graphs. The first graph shows asset-liability maturity ratios on the y-axis against debt maturity periods in years on the x-axis. The ratios range from -4 to 4. The second graph plots net interest income ratios on the y-axis against the scale of total assets in billions of won on the x-axis. The net interest income ratios range from -30% to 70%. Both graphs appear to analyze the relationship between financial metrics and time or asset scales for various institutions.
