Restructuring

We continuously evaluate our cost structure to identify cost savings to streamline our operating model. Our 2017 restructuring plans consisted of a company-wide workforce reduction of approximately 520 positions and are further detailed below. The charges for the restructuring plan are classified as selling and general expenses within the consolidated statements of income and the reserves are included in other current liabilities in the consolidated balance sheets.

In certain circumstances, reserves are no longer needed because of efficiencies in carrying out the plans or because employees previously identified for separation resigned from the Company and did not receive severance or were reassigned due to circumstances not foreseen when the original plans were initiated. In these cases, we reverse reserves through the consolidated statements of income during the period when it is determined they are no longer needed.

The initial restructuring charge recorded and the ending reserve balance as of March 31, 2018 by segment is as follows:
