Compensation and Retirement Disclosure [Abstract] |
Benefit Plans | Benefit Plans Pension Plans San Jose Water Company sponsors a noncontributory defined benefit pension plan (the “Pension Plan”) for its eligible employees. Employees hired before March 31, 2008 are entitled to receive retirement benefits using a formula based on the employee's three highest years of compensation (whether or not consecutive). For employees hired on or after March 31, 2008, benefits are determined using a cash balance formula based upon compensation credits and interest credits for each employee. The Pension Plan is administered by a committee that is composed of an equal number of company and union representatives (the “Committee”). The Committee has retained an investment consultant, Wells Fargo Advisors Financial Network, LLC, to assist it with, among other things, asset allocation strategy, investment policy advice, performance monitoring, and investment manager due diligence. Individual investment decisions have been delegated by the Committee to the investment managers who are monitored by the investment consultant. Investment guidelines provided in the Investment Policy Statement require that at least 25% of plan assets be invested in fixed income securities. As of December 31, 2015, the plan assets consist of approximately 35% bonds, 9% cash equivalents, and 56% equities. Furthermore, equities are to be diversified by industry groups and selected to achieve a balance of long-term growth and income combined with a goal of long-term preservation of capital. Except as provided for in the prospectus of any co-mingled investments, investment managers may not invest in commodities and futures contracts, private placements, options, letter stock, speculative securities, nor may they hold more than 5% of assets of any one private corporation. Except as provided for in the prospectus of any co-mingled investments, fixed income assets may only be invested in bonds, commercial paper, and money market funds with acceptable ratings by Moody's or Standard & Poor's as defined by the Investment Policy Statement. The investment managers performance is reviewed regularly by the investment consultant who provides semi-annual reports to the Committee for review. Plan assets are marked to market at each measurement date, resulting in unrealized actuarial gains or losses. Unrealized actuarial gains and losses on pension assets are amortized over the expected future working lifetime of participants of 12.36 years for actuarial expense calculation purposes. Market losses in 2014 increased pension expense by approximately $3,473 in 2015 and market gains in 2013 decreased pension expense by approximately $790 in 2014. For the past 10 years, the plan has achieved a 5.91% return on its investments while the applicable benchmark was 5.95% for the same period. The applicable benchmark is a weighted-average of returns for those benchmarks shown in the table below. For the past five years, the investment managers, following the required investment guidelines, achieved a 7.41% return on their investments, while the applicable benchmark was 7.13% for the same period. Generally, it is expected of the investment managers that the performance of the assets held in the Pension Plan, computed on a total annual rate of return basis, should meet or exceed specific performance standards over a three-to-five-year period and/or full market cycle. These standards include specific absolute and risk-adjusted performance standards over a three-to-five-year period and/or full market cycle. San Jose Water Company calculates the market-related value of the defined benefit pension plan assets, which is defined under FASB ASC Topic 715—“Compensation—Retirement Benefits” as a balance used to calculate the expected return on plan assets, using fair value. Fair value for San Jose Water Company is based on quoted prices in active markets for identical assets and significant observable inputs. Officers hired before March 31, 2008 are eligible to receive additional retirement benefits under San Jose Water Company's Executive Supplemental Retirement Plan, and officers hired on or after March 31, 2008 are eligible to receive additional retirement benefits under San Jose Water Company's Cash Balance Executive Supplemental Retirement Plan. Both of the plans are non-qualified plans in which only officers and other designated members of management may participate. The annual cost of the plans has been included in the determination of the net periodic benefit cost shown below. The plans, which are unfunded, had a projected benefit obligation of $16,566 and $15,806 as of December 31, 2015 and 2014, respectively, and net periodic pension cost of $1,542, $1,300 and $1,248 for 2015, 2014 and 2013, respectively. Other Postretirement Benefits In addition to providing pension and savings benefits, San Jose Water Company also provides health care and life insurance benefits for retired employees under the San Jose Water Company Social Welfare Plan. The plan is a flat dollar plan which is unaffected by variations in health care costs. Flexible Spending Plan Effective February 1, 2004, San Jose Water Company established a Flexible Spending Account for its employees for the purpose of providing eligible employees with the opportunity to choose from among the fringe benefits available under the plan. The flexible spending plan is intended to qualify as a cafeteria plan under the provisions of the Internal Revenue Code Section 125. The flexible spending plan allows employees to save pre-tax income in a Health Care Spending Account (“HCSA”) and/or a Dependent Care Spending Account (“DCSA”) to help defray the cost of out-of-pocket medical and dependent care expenses. The annual maximum limit under the HCSA and DCSA plans is $2.5 and $5, respectively. Deferral Plan San Jose Water Company sponsors a salary deferral plan that allows employees to defer and contribute a portion of their earnings to the plan. Contributions, not to exceed set limits, are matched by San Jose Water Company. San Jose Water Company contributions were $1,149, $1,101 and $1,087 in 2015, 2014 and 2013, respectively. Special Deferral Election Plan and Deferral Election Program SJW Corp. maintains a Special Deferral Election Plan allowing certain executives and a Deferral Election Program allowing non-employee directors to defer a portion of their earnings each year and to realize an investment return on those funds during the deferral period. Executives and non-employee directors have to make an election on the deferral and distribution method of the deferrals before services are rendered. Executives and non-employee directors had deferred $4,073, $3,463 and $3,203 under the plans as of December 31, 2015, 2014 and 2013, respectively. Assumptions Utilized on Actuarial Calculations Net periodic cost for the defined benefit plans and other postretirement benefits was calculated using the following weighted-average assumptions:
| Pension Benefits |  | Other Benefits
| 2015 |  | 2014 |  | 2013 |  | 2015 |  | 2014 |  | 2013
| % |  | % |  | % |  | % |  | % |  | %
Discount rate | 3.88 |  | 4.82 |  | 3.92 |  | 3.80 |  | 4.70 |  | 3.80
Expected return on plan assets | 7.00 |  | 7.00 |  | 7.00 |  | 7.00 |  | 7.00 |  | 7.00
Rate of compensation increase | 4.00 |  | 4.00 |  | 4.00 |  | N/A |  | N/A |  | N/A
The expected rate of return on plan assets was determined based on a review of historical returns, both for the Pension Plan and for medium- to large-sized defined benefit pension funds with similar asset allocations. This review generated separate expected returns for each asset class. These expected future returns were then blended based on the Pension Plan's target asset allocation. Benefit obligations for the defined benefit plans and other postretirement benefits were calculated using the following weighted-average assumptions as of December 31:
| Pension Benefits |  | Other Benefits
| 2015 |  | 2014 |  | 2015 |  | 2014
| % |  | % |  | % |  | %
Discount rate | 4.24 |  | 3.88 |  | 4.10 |  | 3.80
Rate of compensation increase | 4.00 |  | 4.00 |  | N/A |  | N/A
San Jose Water Company utilized each plan's projected benefit stream in conjunction with the Citigroup Pension Discount Curve in determining the discount rate used in calculating the pension and other postretirement benefits liabilities at the measurement date. In 2014, San Jose Water Company adopted the Society of Actuaries newly issued RP-2014 Mortality Tables and Mortality Improvement Scale MP-2014 to determine mortality assumptions. The newly issued tables and scales reflect increasing life expectancies of participants in the United States. See also “Reconciliation of Funded Status” below.
