Mercer Island Girls Basketball Booster Club finances

From the annual returns the group files with the IRS (Form 990, or the shorter Form 990-EZ for smaller groups), 3 filed years. Net assets are what it owns minus what it owes; management and general is office, admin and insurance cost. A dash means not reported (the short form does not ask for employees or volunteers). Each figure links to that year's return. A year is left out when no return is in the IRS e-file data; that does not mean the group was inactive.

Where the money goes, year ending May 2025

Revenue trend: Steady. Revenue went from $58,977 (year ending May 2020) to $78,546 (May 2025), about +6% a year.

Growth label: we compare total revenue on the oldest and the newest return shown above. Growing means revenue rose by more than 10% a year on average, Shrinking means it fell by more than 10% a year, and Steady means a change between -10% and +10% a year. The rate is the compounded yearly average between the two returns, so it hides ups and downs in between (see the table). We only label groups with returns at least a year apart and at least $5,000 of revenue on the oldest one. This is our own calculation, not an IRS rating or a judgment of quality.
