The middle office comprises departments of a financial services company that manage position-keeping (i.e. control representation of transactions within transaction-registering system of a company). These divisions make sure these transaction representations properly capture profit flows given the technological resources. The middle office is usually part of operations and finance divisions including product control, which normally is also in charge of settlement. It draws on the resources of both the front and the back offices. Due to their critical role, the middle office always acts in tandem with the front office work on open markets. Broadly speaking, middle office includes roles that affect either side (invest, finance, hedge, insure) of the balance sheet of the business.
