employee retires. The same tax deferral rule applies to all pensions. But unlike a "defined benefit" plan, a 401(k) only contains whatever the employer and employee contribute. It will run out if a person lives too long, meaning the retiree may only have minimum social security. The Pension Protection Act of 2006 §902 codified a model for employers to automatically enroll their employees in a pension, with a right to opt out. However, there is no right to an occupational pension. The Employee Retirement Income Security Act of 1974 does create a series of rights for employees if one is set up. It also applies to health care or any other "employee benefit" plan. Five main rights for beneficiaries in ERISA 1974 include information, funding, vesting, anti-discrimination, and fiduciary duties. First, each beneficiary should receive a "summary plan description" in 90 days of joining, plans must file annual reports with the Secretary of Labor, and if beneficiaries make claims any refusal must be justified with a "full and fair review". If the "summary plan description" is more beneficial than the actual plan documents, because the pension fund makes a mistake, a beneficiary may enforce the terms of either. If an employer has pension or other plans, all employees must be entitled to participate after at longest 12 months, if working over 1000 hours. Second, all promises must be funded in advance. The Pension Benefit Guaranty Corporation was established by the federal government to be an insurer of last resort, but only up to $60,136 per year for each employer. Third, employees' benefits usually cannot be taken away (they "vest") after 5 years, and contributions must accrue (i.e. the employee owns contributions) at a proportionate rate. If employers and pension funds merge, there can be no reduction in benefits, and if an employee goes bankrupt their creditors cannot take their occupational pension. However, the US Supreme Court has enabled benefits to be withdrawn by employers simply amending plans. In Lockheed Corp v Spink a majority of seven judges held that an employer could alter a plan, to deprive a 61-year-old man of full benefits when he was reemployed, unbound by fiduciary duties to preserve what an employee had originally been promised. In dissent, Breyer J and Souter J reserved any view on such "highly technical, important matters". Steps to terminate a plan depend on whether it is individual, or multi-employer, and
