BUILDING SOCIETIES

These Rules, which replace the Building Societies (Aggregation) Rules 1990, set out how certain assets and liabilities of bodies associated with building societies are to be attributed to societies for the purposes of the limits in section 7 (power to raise funds and borrow money and limit on non–retail funds and borrowing), 8 (proportion of liabilities to be in the form of shares) and 20 (commercial asset structure requirements) of the Building Societies Act 1986.
