We expect to record pension and postretirement benefit costs of approximately $1.3 million for 2019. Included in these costs is approximately $543,000 related to continued amortization of the FPU pension regulatory asset, which represents the portion attributable to FPU’s regulated energy operations for the changes in funded status that occurred, but were not recognized, as part of net periodic benefit costs prior to the FPU merger in 2009. This was deferred as a regulatory asset by FPU prior to the merger, to be recovered through rates pursuant to a previous order by the Florida PSC. The unamortized balance of this regulatory asset was approximately $351,000 and approximately $543,000 at March 31, 2019 and December 31, 2018, respectively. The other than service cost components of the net periodic costs have been recorded or reclassified to other income (expense), net in the condensed consolidated statements of income.

Pursuant to a Florida PSC order, FPU continues to record, as a regulatory asset, a portion of the unrecognized pension and postretirement benefit costs related to its regulated operations after the FPU merger. The portion of the unrecognized pension and postretirement benefit costs related to FPU’s unregulated operations and Chesapeake Utilities' operations is recorded to accumulated other comprehensive loss.

The following tables present the amounts included in the regulatory asset and accumulated other comprehensive loss that were recognized as components of net periodic benefit cost during the three months ended March 31, 2019 and 2018:

During the three months ended March 31, 2019, we contributed approximately $33,000 to the Chesapeake Pension Plan and approximately $233,000 to the FPU Pension Plan. We expect to contribute a total of approximately $163,000 and approximately $1.2 million to the Chesapeake Pension Plan and FPU Pension Plan, respectively, during 2019, which represents the minimum annual contribution payments required.

The Chesapeake SERP, the Chesapeake Postretirement Plan and the FPU Medical Plan are unfunded and are expected to be paid out of our general funds. Cash benefits paid under the Chesapeake SERP for the three months ended March 31, 2019, were approximately $38,000. We expect to pay total cash benefits of approximately $383,000 under the Chesapeake SERP in 2019. Cash benefits paid under the Chesapeake Postretirement Plan, primarily for medical claims for the three months ended March 31, 2019, were approximately $1,000. We estimate that approximately $96,000 will be paid for such benefits under the Chesapeake Postretirement Plan in 2019. Cash benefits paid under the FPU Medical Plan, primarily for medical claims for the three months ended March 31, 2019, were approximately $6,000. We estimate that approximately $94,000 will be paid for such benefits under the FPU Medical Plan in 2019.
