"We have been careful to retain key engineering and middle management talent – and hence Mercury's unique capabilities and differentiation – during this process in order to preserve the intrinsic value of the business while also increasing its operating leverage," Aslett said. "At the same time, we have ensured that we have sufficient liquidity and financial flexibility, not only to manage the ongoing needs of the business, but also for future M&A purposes when end-market conditions become more favorable. As a result, we believe that Mercury will not only quickly recover when the defense industry returns to a more normal procurement environment, but also be positioned for accelerated growth and improved profitability for the long term."Backlog Mercury's total backlog at September 30, 2012 was $120.2 million, a $15.6 million sequential increase from June 30, 2012, and an $18.4 million increase from September 30, 2011.
