Figures management reported

Risks management discussed

  • Operational: Abnormally low plant utilization would cause part of indirect manufacturing costs to be expensed as incurred rather than absorbed into inventory. Source
  • Financial: Proceeds from selling Section 45X credits may be below the notional credit amount because of pricing, counterparty terms and payment timing. Source
