What the encoder found in the filings

  • final report (2021-08-25) is the optional-termination distribution — modeled as full-balance retirement funded by the termination purchase price.
  • backtest window starts at deal month 11 (2013-12-26); state initialized from that report's reported beginning balances. Floor-provision 'initial' fractions are pinned from this window's first period, not closing — inert for this window (floors cannot bind while subordination is growing).
