Restructuring Charges

In the six months ended June 30, 2019 and 2018, the Company recorded $0.4 million and $0.2 million, respectively, in restructuring costs within operating expenses related to focused reductions of its workforce. The Company began substantially formulating plans around this workforce reduction during the first quarter of 2016 in conjunction with its merger of TriVascular Technologies, Inc. The targeted reductions and other restructuring activities were initiated to provide efficiencies and re-align resources as well as to allow for continued investment in strategic areas and drive growth.

In June 2019, the Company continued its restructuring activities including: restructuring certain aspects of its business and operations to re-prioritize its sales and marketing efforts; rationalizing its international presence and related expenses; streamlining its workforce and taking other measures to increase efficiencies; decreasing its cash consumption and decreasing its cost to serve; and refocusing its business on strong execution of its core strategies. The Company determined to streamline and restructure certain of its operations and implement certain management changes. These plans have resulted in significant changes in the composition of the senior management team.

As of June 30, 2019, the Company estimates that it will incur a total of $16.3 million in restructuring charges upon the completion of the plan, of which $16.3 million has already been incurred since the first quarter of 2016.

The recognition of restructuring charges requires that the Company make certain judgments and estimates regarding the nature, timing and amount of costs associated with the planned reductions of workforce. At the end of each reporting period, the Company will evaluate the remaining accrued balance to ensure that no excess accruals are retained and the utilization of the provisions are for their intended purpose in accordance with developed plans. The following table reflects the movement of activity of the restructuring reserve for the six months ended June 30, 2019:
