For 2018, the expected long‑term rate of return on plan assets is 5.80% for the salaried plan and 6.50% for the hourly plan. To determine the long‑term rate of return assumption for plan assets, the Company studies historical markets and preserves the long‑term historical relationships between equities and fixed‑income securities consistent with the widely accepted capital market principle that assets with higher volatility generate a greater return over the long run. The Company evaluates current market factors such as inflation and interest rates before it determines long‑term capital market assumptions and reviews peer data and historical returns to check for reasonableness and appropriateness.

The investment policy is reviewed periodically in order to achieve overall objectives in light of current circumstances.

The investment strategy is to build an efficient, well‑diversified portfolio based on a long‑term, strategic outlook of the investment markets. The investment market outlook utilizes both historical‑based and forward‑looking return forecasts to establish future return expectations for various asset classes. These return expectations are used to develop a core asset allocation based on the needs of the plan. The core asset allocation utilizes investment portfolios of various asset classes and multiple investment managers in order to help maximize the plan’s return while providing multiple layers of diversification to help minimize risk.

Postretirement benefits

The Company provides postretirement healthcare benefits for certain employee groups.
