RMS' net sales in 2018 increased $587 million, or 4 percent, compared to 2017. The increase was primarily attributable to higher net sales of approximately $525 million for IWSS programs due to higher volume (primarily radar surveillance systems programs and Multi Mission Surface Combatant); and about $250 million for C6ISR programs due to higher volume on multiple programs.
These increases were partially offset by a decrease of approximately $270 million for Sikorsky helicopter programs, which reflect lower volume for Black Hawk production, partially offset by higher volume for CH-53K King Stallion development and for mission systems programs.
RMS' operating profit in 2018 increased $400 million, or 44 percent, compared to 2017. Operating profit increased approximately $185 million for C6ISR programs due to charges of $120 million for performance matters on the EADGE-T contract, recorded in 2017 but which did not recur in 2018, and due to higher risk retirements (primarily undersea systems programs); about $155 million for Sikorsky helicopter programs due to better cost performance across the Sikorsky portfolio and better cost performance on the Multi-Year IX contract; and about $105 million for IWSS programs due to higher risk retirements and higher volume (primarily Aegis). Adjustments not related to volume, including net profit booking rate adjustments and other items, were about $185 million higher in 2018 compared to 2017.
Insurance and Pension
In December 2018, certain of the corporation's pension plans used pension trust assets to purchase group annuity contracts from insurance companies for $2.6 billion.
- One such contract transferred $1.8 billion of our outstanding defined benefit pension obligations related to approximately 32,000 U.S. retirees and beneficiaries to an insurance company. As a result of this transaction, the insurance company is now required to pay and administer the retirement benefits owed to these retirees and beneficiaries.
- The second transaction requires another insurance company to reimburse our pension trust fund for all future benefit payments made to approximately 9,000 U.S. retirees and beneficiaries under a group annuity contract purchased for $0.8 billion.
