Seasonally adjusted changes for the quarterly analysis of advances published by the British Bankers' Association were first given in the September 1963 Bulletin; and this series has since been continued in Financial Statistics. The method of adjustment used has been the modified version of the United States Bureau of the Census Method II-commonly known as Univac-which was also employed until earlier this year to adjust the London clearing banks' monthly figures of deposits and advances.
