Capitalized benefit costs reflected in the table above relate to SJG’s construction program.

SJI contributed $12.7 million to the pension plans in January 2013. No contributions are expected to be made to the pension plans during 2014. Payments related to the unfunded supplemental executive retirement plan (SERP) are expected to approximate $1.3 million in 2014. SJG also has a regulatory obligation to contribute approximately $3.6 million annually to the other postretirement benefit plans’ trusts, less direct costs incurred.

See Note 12 to the Consolidated Financial Statements in Item 8 of SJI’s Annual Report on Form 10-K as of December 31, 2013, for additional information related to SJI’s pension and other postretirement benefits.
