Intensifying regulation, rising operational costs, and increasingly complex investments were cited by the beleaguered airline. British Airways Pensions has transferred management of its two main retirement systems totaling nearly $30.4 billion (£21.5 billion) in assets to the outsourced chief investment officer (OCIO) business at BlackRock. The transfer is among the largest of its kind in the United Kingdom, the firm said Wednesday. The agreement affects assets under the Airways Pension Scheme (APS) and the New Airways Pension Scheme (NAPS), as well as more than 85,000 members. “This agreement is the necessary next step in the evolution of the Schemes as they look to enhance their respective investment strategies, working toward their funding goals,” Roger Maynard, chair of trustees at APS and NAPS, said in a statement.
