The organization over time
Each line starts at 100 in 2024, so what you read is the shape rather than the size: 150 means half as much again as 2024, 50 means half. The number beside each label in the key is where it ended.
Balance sheet
Total assets at each year end, in dollars. The largest one-year move in total assets was 2024 to 2025, from $343k to $377k (+10%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 0 of the last 2 reported years ran a deficit.
