Transparency International has just published a study of anti-corruption programs in defense contracting—so all you compliance executives eager for more examples of successful programs at real businesses, break out the reading glasses.

The report, “Raising the Bar: Good anti-corruption programs in defense companies,” is a detailed look at the compliance programs of 129 defense contractors around the world. Each company’s program is rated on a scale from A (excellent) to F (terrible), based on what the company publicly discloses about its compliance program, as well as its answers to a 34-question survey TI sent to each business.
