The eligibility criteria for the Pension Protection Fund are set out in the Pensions Act 2004.
The Nortel Networks UK Pension Plan entered a Pension Protection Fund assessment period in March 2009. During an assessment period, the board of the Pension Protection Fund establishes whether the scheme can be rescued; whether it can afford to secure benefits which are at least equal to the compensation that the Pension Protection Fund would pay; or whether the scheme is eligible for compensation from the Pension Protection Fund.
