Discontinued Operations, Assets Held for Sale and Divestitures
Restructuring and Discontinued Operations
In January 2014, Mueller Co. changed its approach to the production of certain sizes of iron gate valves. This change resulted in an impairment of the related production equipment of $1.5 million, which is reported as restructuring expense for the nine months ended June 30, 2014. This charge was based on our internal projections of future cash flows associated with the production equipment.
In April 2014, Anvil sold the production equipment and certain inventory at its Bloomington, Minnesota location for an immaterial gain. Anvil also signed a supply agreement with the buyer and terminated the employment of all employees at that location, which resulted in the withdrawal from the only multi-employer pension plan in which the Company had participated. At June 30, 2014, we maintained an accrual for our estimated withdrawal liability of $1.0 million. Also in April 2014, Anvil entered into an agreement to sell the land and buildings at this location, which had a net book value of $0.8 million at June 30, 2014, for estimated net proceeds of $3.5 million. We expect this sale will close during the second half of calendar 2014.
On April 1, 2012, we sold our former U.S. Pipe segment. During 2013, we received $4.5 million in cash for certain purchase price adjustments and reduced our loss on sale of discontinued operations accordingly.
Activity related to U.S. Pipe is presented as discontinued operations for the three and nine months ended June 30, 2013. The table below represents a summary of the operating results for these discontinued operations.

We retained certain assets, liabilities and activities previously associated with our former U.S. Pipe segment, including ownership of certain real property and retention of pension and workers compensation obligations to employees of U.S. Pipe. Cash flows associated with some of these items are anticipated to continue indefinitely, but they are not clearly and closely related to the future operations of U.S. Pipe under its new ownership.
