Defined Benefit Plan Disclosure [Line Items] |
Pension Benefits | Pension Benefits Defined Benefit Pension Plans We sponsor multiple defined benefit pension plans that covered certain workers under collective bargaining contracts. However, as a result of prior-years’ restructuring activities, for all periods presented, we no longer have any active employees continuing to accrue service cost or otherwise eligible to receive plan benefits. Benefits being paid under the plans are primarily based on negotiated rates and years of service. We contribute to these plans at least the minimum amount required by regulation. At the end of the year, we discount our plan liabilities using an assumed discount rate. In estimating this rate, we, along with our third-party actuaries, review the timing of future benefit payments, bond indices, consider yield curve analysis results and the past history of discount rates. The actuarial present value of benefit obligations summarized below was based on the following assumption:
| 2015 |  | 2014
Weighted-average assumption as of June 30 |  |  |
Discount rate | 4.12 | % |  | 4.02 | %
The net periodic benefit costs were determined utilizing the following beginning-of-the-year assumptions:
| 2015 |  | 2014 |  | 2013
Discount rate | 4.02 | % |  | 4.57 | % |  | 3.78 | %
Expected long-term return on plan assets | 7.00 | % |  | 7.00 | % |  | 7.00 | %
In determining the long-term expected return on plan assets, we consider our related investment guidelines, our expectations of long-term rates of return by asset category, our target asset allocation weighting and historical rates of return and volatility for equity and fixed income investments. The investment strategy for plan assets is to control and manage investment risk through diversification among asset classes, investment managers/funds and investment styles. The plans’ investment guidelines have been designed to meet the intended objective that plan assets earn at least nominal returns equal to or in excess of the plans’ liability growth rate. In consideration of the current average age of the plans’ participants, the investment guidelines are based upon an investment horizon of at least 10 years. The target and actual asset allocations for our plans at June 30 by asset category were as follows:
| Target Percentage of Plan Assets at June 30 |  | Actual Percentage of Plan Assets
| 2015 |  | 2015 |  | 2014
Cash and equivalents | 0%-10% |  | 2 | % |  | 3 | %
Equity securities | 30%-70% |  | 49 |  |  | 53 |
Fixed income | 30%-70% |  | 49 |  |  | 44 |
Total |  |  | 100 | % |  | 100 | %
Our target asset allocations are maintained through ongoing review and periodic rebalancing of equity and fixed income investments with assistance from an independent outside investment consultant. Also, the plan assets are diversified among asset classes, asset managers or funds and investment styles to avoid concentrations of risk. We expect that a modest allocation to cash will exist within the plans because each investment manager is likely to hold limited cash in a portfolio. We categorize our plan assets within a three-level fair value hierarchy as follows: Level 1 – Quoted market prices in active markets for identical assets. Level 2 – Observable market based inputs or unobservable inputs that are corroborated by market data. Level 3 – Unobservable inputs that are not corroborated by market data. The following table summarizes the fair values and levels, within the fair value hierarchy, for our plan assets at June 30:

The plan assets classified at Level 1 include money market funds and mutual funds. Quoted market prices in active markets for identical assets are available for investments in this category. The plan assets classified at Level 2 include fixed income securities consisting of government securities, municipal obligations, corporate obligations and mortgage obligations. For these types of securities, market prices are observable for identical or similar investment securities but not readily accessible for each of those investments individually at the measurement date. For these assets, we obtain pricing information from an independent pricing service. The pricing service uses various pricing models for each asset class that are consistent with what other market participants would use. The inputs and assumptions to the model of the pricing service are derived from market observable sources including as applicable: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data including market research publications.
