Compensation and Retirement Disclosure [Abstract]
Employee Benefit Plans	Employee Benefit Plans Effective November 1, 2000, the Company established an unfunded deferred compensation plan to provide benefits to executive officers and other key employees. Under the plan, participants can defer any portion of their salary and bonus compensation into the plan and may choose from a portfolio of funds from which earnings are measured. Participant balances are always 100% vested. As of September 30, 2012 and April 1, 2012, obligations under the plan totaled approximately $15.4 million, respectively. Additionally, the Company has set aside assets in a separate trust that is invested in corporate owned life insurance intended to substantially fund the liability under the plan. As of September 30, 2012 and April 1, 2012, the deferred compensation plan assets were approximately $16.3 million and $14.0 million, respectively. During the first quarter of fiscal 2013, the Company assumed an unfunded deferred compensation plan associated with the acquisition of Fox Enterprises. Under this plan, participants on retirement are entitled to receive a fixed amount from the Corporation on a monthly basis. The Company has purchased life insurance policies with the intention of funding the liability under this plan. As of September 30, 2012, the deferred compensation plan assets and liability under this plan were approximately $0.6 million and $1.5 million, respectively. During the second quarter of fiscal 2013, as a result of completion of acquisition of NXP B.V, the Company acquired certain assets and liabilities from NXP B.V related to defined-benefit pension plans, defined-contribution plans, multi-employer plans and certain post-employment benefit plans as explained below, for its employees mainly in France and Netherlands. The costs of pension benefits and related liabilities for the employees that were transferred to the Company as a result of the acquisition, were determined based on actuarial calculations. Multi-employer plan The Company's employees in the Netherlands participate in a mandatory multi-employer plan, implemented for the employees of the Metal and Electrical Engineering Industry. As this affiliation is a legal requirement for the Metal and Electrical Engineering Industry it has no expiration date. The pension fund rules state that the only obligation for affiliated companies will be to pay the annual plan contributions. Affiliated companies will also have no entitlements to any possible surpluses in the pension fund. Contributions to multi-employer pension plans are recognized as an expense in the statements of operations as incurred. During the second quarter of fiscal 2013, the Company made $0.1 million of contribution under this plan. The total expected contribution under the plan for fiscal 2013 is approximately $0.4 million. Defined-benefit plan The benefits provided by defined-benefit plans are based on employees' years of service and compensation levels. Contributions are made by the Company, as necessary, to provide assets sufficient to meet the benefits payable to defined-benefit pension plan participants. These contributions are determined based upon various factors, including funded status, legal and tax considerations as well as local customs. Some of these defined-benefit pension plans are funded with plan assets that have been segregated and restricted in a trust, foundation or insurance company to provide for the pension benefits to which the Company has committed itself. The projected defined-benefit obligation will be calculated at year-end by qualified actuaries using the projected unit credit method. Actuarial gains and losses arise mainly from changes in actuarial assumptions and differences between actuarial assumptions and what has actually occurred will be recognized in the statement of operations, over the expected average remaining service periods of the employees only to the extent that their net cumulative amount exceeds 10% of the greater of the present value of the obligation or of the fair value of plan assets at the end of the previous year. Events which invoke a curtailment or a settlement of a benefit plan will be recognized in our statement of operations. As of September 30, 2012, the total plan assets and liability under all pension plans were approximately $0.7 million each. The Company also assumed obligations for post employment benefits liability of $0.2 million from NXP B.V under the Jubilee plan ("Jubilee"). These are in the nature of one time payouts in relation to the number of service years of the employee. The amount of the obligation per employee has been determined by actuarial calculation indicating the degree of likelihood that the individual employee will actually complete the required number of service years to be entitled to his jubilee payment.
