The file linked here Pledge and Budget Info 2021 contains a comparison of the current year budget and initial estimates of what next year expenses and income may be.
From these values, one can determine a target for total pledges, and a summary of factors that contribute to the increased need for pledges is described. Hopefully this provides the full context to understand the request that has been made.
