The transaction, which comprises a £2.1 billion savings book and £400 million mortgage book, complements the Yorkshire's core mortgage and savings business and will enhance the Society's ability to deliver greater value to members through a wider product and service offering and increased lending in 2012.
Egg savers and borrowers have now become members of Yorkshire Building Society and benefit from being part of an independent mutual focused on providing members with financial security and good, long-term value products backed up with excellent customer service.
Egg borrowers currently paying Egg Standard Variable Rate (SVR) or Egg Pi SVR have seen an immediate benefit as their mortgage accounts have been automatically transferred onto Yorkshire's lower SVR.
Iain Cornish, chief executive of Yorkshire Building Society, said:
"The acquisition of the Egg mortgage and savings book adds further scale to our business and strengthens the long term position of the Society.
"Combining Yorkshire and Egg product capabilities will lead to further innovation and a more extensive product offering to our current and future members, enabling us to be even better placed to compete in the UK retail financial services market.
"I'm pleased to welcome Egg customers to the Yorkshire where we are fully committed to maintaining the outstanding service, administration and value they have enjoyed with Egg."
