Non-GAAP Reconciliations 23

Footnotes 24 1) With respect to our forward-looking expectations regarding Adjusted EBITDA, we do not provide a reconciliation to the applicable GAAP metric because we are not able to predict with reasonable certainty the reconciling items that may affect GAAP net sales without unreasonable effort. The reconciling items are uncertain, depend on various factors and could significantly impact, either individually or in the aggregate, the GAAP metric. The Company also believes such reconciliations would imply a degree of precision that would be confusing or misleading to investors.
