Provide sufficient details of scientific progress. Discuss clearly the extent to which progress has contributed to the objectives of the project. Discuss unexpected findings (both positive and negative). Problems should be interpreted in terms of their probable effects on the likelihood and cost of attaining the project's objectives.

These should be more detailed than progress reports. They should present and assess the overall findings, and indicate the degree to which project objectives were met, in sufficient detail. They should also indicate any potentially fruitful new lines of research indicated by the results of the project. Additional pages, including graphs and tables, should be attached if they relate to the work reported on.
