Title VI, SEC. 6107. FAMILY COLLECTION SHORTFALL ADD-ON. (a) In General. The family collection shortfall add-on, for a regional alliance for a class of enrollment for a year, is the amount that would be the weighted average premium for such alliance, class, and year, if the per capita collection shortfall amount (determined under subsection (b)) for the alliance for the year were substituted for the reduced weighted average accepted bid for the regional alliance for the year. (b) Computation of Per Capita Adjustment for Collection Shortfalls. (1) Per capita collection shortfall amount . The per capita collection shortfall amount, for a regional alliance for a year, under this subsection is equal to (A) the amount estimated under paragraph (2)(A) for the year, divided by (B) the estimated average number of regional alliance eligible individuals in the regional alliance during the year (reduced by the average number of such individuals whose family share of premiums, determined without regard to this section and section 6106, is zero). (2) Aggregate collection shortfall. (A) In general. Each regional alliance shall estimate, for each year (beginning with the first year) the total amount of payments which the alliance can reasonably identify as owed to the alliance under this Act (taking into account any premium reduction or discount under this subtitle and including amounts owed under subpart B and not taking into account any penalties) for the year and not likely to be collected (after making collection efforts described in section 1345) during a period specified by the Secretary beginning on the first day of the year. (B) Exclusion of government debts. The amount under subparagraph (A) shall not include any payments owed to a regional alliance by the Federal, State, or local governments. (C) Adjustment for previous shortfall estimation discrepancy. Subject to section 1361(b)(3), the amount estimated under this paragraph for a year shall be adjusted to reflect over (or under) estimations in the amounts so computed under this paragraph for previous years (based on actual collections), taking into account interest payable based upon borrowings (or savings) attributable to such over or under estimations.
