Where do you get "under 50%"?

If you're looking at https://www.zidisha.org/statistics, you might be confused by

  Principal repaid: $607,262 (44.9% of amount disbursed)

This is for all loans made within the last year, many of which are very recent. You should add the line

  Principal held by borrowers repaying on time: $581,565 (43.0% of amount disbursed)

to get 87.9% either repaid or in good standing.
