(7) Wheeler Bros., Inc. Acquisition
On June 6, 2011, we acquired WBI, a supply chain management company that supplies vehicle parts to the USPS and DoD. We see significant opportunities for leveraging WBI's supply chain capabilities with our work of extending the service lives of legacy ships, vehicles, aircraft and their systems.
Cash paid at closing was $180 million, which includes approximately $1.9 million of prepaid retention bonuses that are being expensed in the post-acquisition period as the employees provide service. As such, the initial cash purchase price was approximately $178.1 million. WBI's results of operations are included in the accompanying Unaudited Condensed Consolidated Statements of Income beginning June 6, 2011. Additional cash consideration of $3 million was paid to the sellers during the first quarter of 2012 based on the final working capital adjustment that was recorded as additional goodwill and an accrued liability during December 2011.
We may be required to make additional payments of up to $40 million over a four-year post-closing period if WBI achieves certain financial performance targets. WBI achieved required financial performance targets for the earn-out period ended June 30, 2012. Approximately $7.1 million was paid to the sellers in September 2012 based on WBI's performance during the earn-out period. Included in earn-out obligations on the September 30, 2012 balance sheet is an earn-out obligation of approximately $8.9 million, of which the current portion of $1.1 million is classified in current portion of earn-out obligations, which represents our best estimate of the present value of the earn-out obligation. Changes in the fair value of the earn-out obligations are recognized in earnings in the period of change through settlement.
