[1] Results for the fourth quarter of 2013 were favorably impacted by a credit to income of approximately $518 for the reversal of a liability recorded in purchase accounting for a recent acquisition that is no longer needed due to statute expiration in the current quarter, and a credit to income of approximately $425 for net reserve reductions at certain of the Company’s vacant leased properties, for which a change in circumstances in the current quarter required a revision in the estimate of future expenses related to the leases. In addition, results for the current quarter were favorably impacted by a credit to income of approximately $736 for the correction of an error in the valuation of unbilled services that was immaterial to all prior periods presented.

[2] In the second quarter of 2013, the Company reclassified the Consolidated Statements of Comprehensive Income (Loss) to disaggregate the discontinued operations related to the sale of its large format printing operation, which was sold on July 3, 2013. In addition, in the second quarter of 2013, the Company changed the presentation of certain expense items on the Consolidated Statements of Comprehensive Income (Loss). The Company previously presented cost of goods sold with a sub-total for gross profit; however, in order to be consistent with how management views the business, production expenses are now presented as cost of services and the gross profit sub-total has been eliminated. In addition, depreciation and amortization is now excluded from and presented separately for both cost of services and selling, general and administrative expenses. Accordingly, in this Form 10-K, the financial data for quarters which have not previously been reported have been reclassified to conform with the current presentation regarding discontinued operations and the revised expense format.

[3] Results for the fourth quarter of 2012 were unfavorably impacted by the Company's decision to withdraw from the Graphic Communications Conference International Brotherhood of Teamsters National Pension Fund. An estimated withdrawal liability of $31,683 was recorded in the fourth quarter of 2012.
