for net periodic pension costs and net periodic postretirement benefit costs. The 2018 adoption of ASU 2017-07 required that non-service related pension expense and income items no longer be included in salaries and employee benefits in the Company’s income statement. The non-service related pension expense and income items are instead included in other expenses. Previously reported salaries and employee benefits and other expenses have been restated to reflect the retrospective adoption. The amount added to salaries and employee benefits and deducted from other expenses from the adoption of ASU 2017-07 during the quarter ended June 30, 2018 was approximately $225,000. The retrospective application for the quarter ended June 30, 2017 was a decrease in salaries and employee benefits and an increase in other expenses of approximately $62,000.

Noninterest expense increases were partially offset by lower other expenses of $177,000 resulting from the adoption of ASU 2017-07 as discussed above, lower marketing expense of $137,000, lower data processing costs of $107,000, and lower occupancy and equipment expense of $106,000 for the quarter ended June 30, 2018, as compared to June 30, 2017.  

Total noninterest expense increased by $1.6 million, or 5.4%, to $31.3 million for the six months ended June 30, 2018, as compared to $29.7 million for the six months ended June 30, 2017, primarily driven by higher salaries and employee benefits expense.

The amount added to salaries and employee benefits and deducted from other expenses from the adoption of ASU 2017-07 for the six months ended June 30, 2018 was approximately $449,000. The retrospective application for the six months ended June 30, 2017 was a decrease in salaries and employee benefits and an increase in other expenses of approximately $119,000.

Noninterest expense increases were partially offset by lower other expenses of $595,000 resulting from the adoption of ASU 2017-07 as discussed above, lower data processing costs of $200,000, and lower occupancy and equipment expense of $132,000 for the six months ended June 30, 2018, as compared to the six months ended June 30, 2017.
