Within the Precision Bearing Components Group, restructuring initiatives to optimize operations in the U.S., Italy, the Netherlands, Mexico and at segment headquarters resulted in a charge of $0.3 and $1.7 million for the three months ended June 30, 2017 and 2016, respectively, and $0.4 and $2.4 million for the six months ended June 30, 2017 and 2016. These charges consisted primarily of severance and other employee costs relating to personnel reductions.

Within the Autocam Precision Components Group, certain restructuring programs, including the closure of one facility, the Wheeling Plant, resulted in a charge of $6 thousand and $2.1 million for the three months ended June 30, 2017 and 2016, respectively, and $16 thousand and $3.6 million for the six months ended June 30, 2017 and 2016.

The total restructuring and impairment costs are still being identified at the various segments; therefore, we are not able to estimate the ultimate costs at this time. We will include in future filings updates to these activities along with a reconciliation of beginning and ending liabilities recorded. The amounts recorded for the three and six months ended June 30, 2017, for restructuring charges that have been incurred are primarily expected to be paid out during 2017. Some amounts related to foreign locations extend through 2021.
