Secured credit facility description   The amendments to the senior secured revolving credit facility and the senior secured term loan also include a reduction to the minimum adjusted EBITDA levels and reduce the seasonal availability blocks imposed from December 20th to January 20th of each year from $12.5 million to $11.5 million and from January 21st to February 10th from $5.0 million to $4.0 million. Failure to meet the minimum adjusted EBITDA covenant (calculated on a twelve-month rolling basis as defined in the agreement) in the event that excess availability falls below $6.0 million for any five consecutive business days is considered an event of default under the amended agreements, that could result in the outstanding balances borrowed under the Company’s senior secured term loan and senior secured revolving credit facility becoming due immediately, which would result in cross defaults on the Company’s other borrowings.
