EMPLOYEE RELATED LIABILITIES | NOTE 14 - EMPLOYEE RELATED LIABILITIES
| A. | Employee Termination Benefits
Israeli law, labor agreements and corporate policy determine the obligations of Tower to make severance payments to dismissed Israeli employees and to Israeli employees leaving employment under certain circumstances. Generally, the liability for severance pay benefits, as determined by Israeli law, is based upon length of service and the employee’s monthly salary. This liability is primarily covered by regular deposits made each month by Tower into recognized severance and pension funds and by insurance policies maintained by Tower, based on the employee’s salary for the relevant month. The amounts so funded and the liability are included on the balance sheets in long-term investments and employee related liabilities in the amounts of $10,711 and $12,258, respectively, as of December 31, 2017. Commencing January 1, 2005, Tower implemented a labor agreement with regard to most of its Israeli employees, according to which monthly deposits into recognized severance and pension funds or insurance policies will release it from any additional severance obligation in excess of the balance in such accounts to such Israeli employees and, therefore, Tower incurs no liability or asset with respect to such severance obligations and deposits, since that date. Any net severance amount as of such date will be released on the employee’s termination date. Payments relating to Israeli employee termination benefits were $5,059, $4,345 and, $3,986 for 2017, 2016 and 2015, respectively. TPSCo established a Defined Contribution Retirement Plan (the “DC Plan”) for its employees through which TPSCo contributes approximately 10% with employee average match of 1% from employee base salary to the DC Plan. Such contribution releases the employer from further obligation to any payments upon termination of employment. The contribution is remitted either to third party benefit funds based on employee preference, or directly, to those employees who elected not to enroll in the DC Plan. Total payments under the DC Plan in 2017, 2016 and 2015 amounted to $6,706, $7,015 and $6,823, respectively.

Jazz’s pension plan weighted average asset allocations on December 31, 2017, by asset category are as follows:
Asset Category |  | December 31, 2017 |  |  | Target allocation 2018 |
Equity securities |  |  | 61 | % |  |  | 60 | %
Debt securities |  |  | 39 | % |  |  | 40 | %
Total |  |  | 100 | % |  |  | 100 | %
Jazz’s primary policy goals regarding the plan’s assets are cost-effective diversification of plan assets, competitive returns on investment and preservation of capital. Plan assets are currently invested in mutual funds with various debt and equity investment objectives. The target asset allocation for the plan assets is 40% debt, or fixed income securities, and 60% equity securities. Individual funds are evaluated periodically based on comparisons to benchmark indices and peer group funds and investment decisions are made by Jazz in accordance with the policy goals. Actual allocation to each asset category fluctuates and may not be within the target specified above due to changes in market conditions. The estimated expected return on assets of the plan is based on assumptions derived from, among other things, the historical return on assets of the plan, the current and expected investment allocation of assets held by the plan and the current and expected future rates of return in the debt and equity markets for investments held by the plan. The obligations under the plan could differ from the obligation currently recorded, if management's estimates are not consistent with actual investment performance.
