An important part of human discourse is the use of language to describe phenomena, the non interactive construction of sentences to convey to others meaningful statements about the external world. Those sentences are conditioned partly by the language itself, partly by the phenomena which is being described. It is fully possible that part of these descriptive activities, the construction of sentences to picture observable phenomena, could be performed by machine. This paper discusses a general program which composes narrative descriptions of the financial results of individual corporations. The descriptions are designed to be fully reflective of the data, accurate, comparable to descriptions prepared by financial writers, stylistically varied and grammatically correct. Since the form of reporting corporate financial data is uniform and the data for all major firms available on tape, the program has general applicability. The paper describes the general process of financial description, the concepts used in replicating of this process by a computer program and the major elements used in the design of the program.
