[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.
