How these figures are made. BRB lists every county an issuer serves and gives no shares, so an issuer's debt counts in its home county, the first county listed for it, and each dollar counts once statewide. Of Collin County's $24,418,778,124, $97,540,000 is owed by 3 issuers that list other counties too; 3 issuers that list Collin County count in another. Total principal outstanding: principal outstanding at the fiscal year end, summed over the local governments attributed to the county. "Not reported" is never shown as zero.
