was this 'labyrinthine' structure, where Group Board members need to remain elected to Area Committees and regional boards, which led to the governance problems at the Co-op and its financial crisis of 2013. Dividend and membership scheme The idea of co-operative trading revolutionised food retailing with the dividend, often known as "divi", and the "divi number" became a part of British life. The way in which co-operative retail societies are run for the benefit, and on behalf of their members sets them apart from their modern-day competitors. The dividend is a financial reward to members based on each member's level of trade with the society. The distribution of profits on the basis of turnover rather than capital invested is a fundamental difference between a co-operative and most private sector enterprises. History of co-op membership Historically, members' sales would be recorded in ledgers in society's stores and at the end of the collection period a proportional payment would be made to the member. As the societies grew, and the number of members increased, the method of using ledgers became cumbersome. As a solution, some societies, including Co-operative Retail Services, issued stamps to members for qualifying transactions. Members collected stamps on a savings card and, when the card was complete, would use it as payment for goods or deposit into their share account. By the late 20th century the group's predecessors and then the Co-operative Group no longer paid true dividend as it had become a drain on limited resources, although several independent societies (such as Anglia Regional) continued to do so. In the mid-1990s a loyalty card scheme, in the style of the Tesco Clubcard, was introduced which used the dividend brand. These loyalty cards were inspired by the co-operative dividend but were little more than marketing exercises and a way to gather useful customer information. Co-operative customers, not just members, could sign up and receive a swipe card to record purchases with vouchers sent out twice a year which could be exchanged for cash or goods. In September 2006 the Co-operative Group relaunched "true" dividend whereby a proportion of the profits of the Co-operative Group is returned to members. To emphasise the change, the scheme is now called the Co-operative Membership and members earn a "share of the profits". New members are recruited by allowing them to deduct the refundable subscription for a £1 share from their first dividend. Members
