Companies with publicly traded equity securities that sponsor a postretirement benefit plan are required to fully recognize, as an asset or liability, the overfunded or underfunded status of its benefit plans and recognize changes in the funded status in the year in which the changes occur. Changes in funded status are generally reported in AOCL; however, since the Utilities recover all prudently incurred pension and postretirement benefit costs from its ratepayers, a significant portion of the changes resulting from the recording of additional liabilities under this requirement is reported as regulatory assets.

No contributions were made to the pension plans by either SJI or SJG during the three months ended March 31, 2019 or 2018. SJI and SJG do not expect to make any contributions to the pension plans during the remainder of 2019; however, changes in future investment performance and discount rates may ultimately result in a contribution. Payments related to the unfunded SERP are expected to be approximately $3.6 million in 2019.

As part of the Acquisition, SJI acquired ETG's and ELK's existing pension and other post-employment benefit plans. The plans include a qualified defined benefit, trusteed, pension plan covering most eligible employees. The qualified pension plan is funded in accordance with requirements of the ERISA. The Company also provides certain non-qualified defined benefit and defined contribution pension plans for a selected group of the Company's management and highly compensated employees. Benefits under these non-qualified pension plans are funded on a cash basis. In addition, the entities also have a postretirement benefit plan, which provides certain medical care and life insurance benefits for eligible retired employees through a postretirement benefit plan.
