business disruptions (such as the inability to timely process shipments);

and significant remediation costs.

This cyber incident, or any future cyber incident could also result in increased vulnerability to attempts of fraud, legal claims and proceedings including potential breach of contract claims, reporting delays or errors;

an increase in costs to protect our systems and technology;

or damage to our reputation.
