Under the terms of the settlement, PIMCO agreed to pay to the SEC a civil monetary penalty in the amount of $2.5 million. Prior to the SEC’s investigation, PIMCO had identified the error, publicly disclosed the issue and implemented a plan that reimbursed A4 and its shareholders for any losses associated with the fee waiver miscalculation.
