Benefit Plans

Pension and Postretirement Health Care Benefit Plans

CNA sponsors noncontributory defined benefit pension plans, primarily through the CNA Retirement Plan, covering certain eligible employees. These plans are closed to new entrants. CNA's funding policy for defined benefit pension plans is to make contributions in accordance with applicable governmental regulatory requirements with consideration of the funded status of the plans.

Effective January 1, 2000, the CNA Retirement Plan was closed to new participants. Existing participants at that time were given a choice to either continue to accrue benefits under the CNA Retirement Plan or to cease accruals effective December 31, 1999. Employees who chose to continue to accrue benefits under the plan received benefits in accordance with plan provisions through June 30, 2015 as discussed further below. Employees who elected to cease accruals effective December 31, 1999 received the present value of their accrued benefit in an accrued pension account that is credited with interest based on the annual rate of interest on 30-year Treasury securities. These employees also receive certain enhanced employer contributions in the CNA 401(k) Plus Plan.

Effective June 30, 2015, the Company eliminated future benefit accruals associated with the CNA Retirement Plan. Participants continuing to accrue benefits under the CNA Retirement Plan at that time were entitled to an accrued benefit payable based on their eligible compensation and accrued service through June 30, 2015. These employees also began receiving enhanced employer contributions in the CNA 401(k) Plus Plan similar to employees who elected to cease accruals effective December 31, 1999. Employees who elected to cease accruals effective December 31, 1999 were not affected by this curtailment. This curtailment resulted in a $55 million decrease in the CNA Retirement Plan benefit obligation liability and a reduction of the unrecognized actuarial losses included in AOCI.

In 2016, the CNA Retirement Plan paid $88 million to settle its obligation to certain retirees through the purchase of a group annuity contract from a third party insurance company. This transaction reduced the plan’s projected benefit obligation by $86 million.

CNA provides certain health care benefits to eligible retired employees, their covered dependents and their beneficiaries primarily through the CNA Health and Group Benefits Program. These postretirement benefits have largely been eliminated for active employees.

The following table presents a reconciliation of benefit obligations and plan assets.

To determine the discount rate assumption as of the year-end measurement date for the CNA Retirement Plan and CNA Health and Group Benefits Program, the Company considered the estimated timing of plan benefit payments and available yields on high quality fixed income debt securities. For this purpose, high quality is considered a rating of Aa or better by Moody's or a rating of AA or better from S&P. The Company reviewed several yield curves constructed using the cash flow characteristics of the plans as well as bond indices as of the measurement date. The trend of those data points was also considered.

In determining the expected long term rate of return on plan assets assumption for the CNA Retirement Plan, CNA considered the historical performance of the benefit plan investment portfolio as well as long term market return expectations based on the investment mix of the portfolio and the expected investment horizon.

The CNA Health and Group Benefits Program has limited its share of the health care trend rate to a cost-of-living adjustment of 4% per year. For all participants, the employer subsidy on health care costs will not increase by more than 4% per year. As a result, the assumed health care cost trend rate used in measuring the accumulated postretirement benefit obligation for the CNA Health and Group Benefits Program was 4% per year in 2017, 2016 and 2015.

CNA employs a total return approach whereby a mix of equity, limited partnerships and fixed maturity securities are used to maximize the long term return of retirement plan assets for a prudent level of risk and to manage cash flows according to plan requirements. The target allocation of plan assets is 40% to 60% invested in equity securities and limited partnerships, with the remainder primarily invested in fixed maturity securities. Alternative investments, including limited partnerships, are used to enhance risk adjusted long term returns while improving portfolio diversification. The intent of this strategy is to minimize the Company's expense related to funding the plan by generating investment returns that exceed the growth of the plan liabilities over the long run. Risk tolerance is established after careful consideration of the plan liabilities, plan funded status and corporate financial conditions.

As of December 31, 2017, the Plan had committed approximately $100 million to future capital calls from various third-party limited partnership investments in exchange for an ownership interest in the related partnerships. Derivatives may be used to gain market exposure in an efficient and timely manner. Investment risk is measured and monitored on an ongoing basis through annual liability measurements, periodic asset/liability studies and quarterly investment portfolio reviews.

Pension plan assets measured at fair value on a recurring basis as well as cash are presented in the following tables.

(1) Certain investments that are measured at fair value using the net asset value per share (or its equivalent) practical expedient have not been classified in the fair value hierarchy. The fair value amounts presented in this table for these investments are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the Plan's Statement of Financial Position.

The limited partnership investments held within the plan are recorded at fair value, which represents the plan's share of net asset value of each partnership, as determined by the general partner. Limited partnerships comprising 85% and 86% of the carrying value as of December 31, 2017 and 2016 employ hedge fund strategies that generate returns through investing in marketable securities in the public fixed income and equity markets and the remainder were primarily invested in private debt and equity. Within hedge fund strategies, approximately 62% were equity related, 32% pursued a multi-strategy approach and 6% were focused on distressed investments as of December 31, 2017.

For a discussion of the fair value levels and the valuation methodologies used to measure fixed maturity securities, equities, derivatives and short term investments, see Note C to the Consolidated Financial Statements.
