Employees of the Company's Wambo Underground Mine operate under a separate labor agreement. That agreement expired in April 2015. The parties agreed to an initial rollover for 12 months through April 2016 and agreed to a further rollover for another 12 months through April 2017. There were no wage increases for the two rollover periods and there have been no disruptions to the operation of the site as a result of the expiration of the agreement. Hourly employees of this mine comprise approximately 8% of the Company's Australian subsidiaries hourly employees, who generated approximately 10% of the Company's Australian production during the year ended December 31, 2016.

Employees of the Company's Metropolitan mine operate under a separate labor agreement, which expired in September 2015. Negotiations progressed to a vote on the Company’s best offer in November 2015, which was rejected by the employees. The parties agreed to hold off on any further negotiations until the Company's emergence from the Chapter 11 Cases, expected to occur in early April 2017. There were no wage increases during this period and there have been no disruptions to the operation of the site as a result of the expiration of the agreement. There is also a Deputy labor agreement which expired in September 2015. The parties agreed to a rollover for 18 months through to December 2016.

⁽⁴⁾

Employees of the Company's Millennium mine operate under a separate labor agreement. Negotiations have been ongoing for an extended period of time, where employees rejected the Company's offers in July 2016 and again in November 2016. After the second unsuccessful vote the Company informed employees it was in the process of applying for the agreement to be terminated. Employees requested the Company to vote again on the second rejected agreement with the intent to accept the offer, 70% of employees voted and accepted the offer late January 2017. The agreement was approved by the Fair Work Commission in early March 2017. Hourly employees of this mine comprise approximately 16% of the Company's Australian subsidiaries hourly employees, who generated approximately 11% of the Company's Australian production during the year ended December 31, 2016.

Employees of the Company's Wilpinjong Mine operate under an enterprise agreement. Negotiations to replace the enterprise agreement that nominally expired in May 2016 commenced in April 2016. In January 2017 the workforce formally rejected Wilpinjong’s proposed replacement agreement and good faith negotiations are now continuing. Hourly employees of this mine comprise approximately 18% of the Company's Australian subsidiaries hourly employees, who generated approximately 42% of the Company's Australian production during the year ended December 31, 2016.

Employees of the Company's Coppabella/Moorvale Coal Handling and Preparation Plant facility previously operated under a separate enterprise agreement. As a result of the latest negotiation process the Company was successful in its application to terminate the agreement. The negotiations resulted in the Coppabella employees requesting to be employed on individual salaried contracts (rather than a labor agreement) and the Moorvale employees accepted the Company's final offer. The Moorevale agreement expires in October 2019. Hourly employees of this mine comprise approximately 28% of the Company's Australian subsidiaries hourly employees, who generated approximately 13% of the Company's Australian production during the year ended December 31, 2016.
