Preliminary Remark

Diehl carries out its business activities both in agreement with the laws and regulations of public authorities in the countries where its employees work and in accordance with the principles described here; all employees on all hierarchical levels are to comply with them without exception. Unfair or even illegal practices are not compatible with our business principles.

1.1. Bribery / Corruption

Diehl forbids every kind of bribery. No employee may offer, provide, or accept bribes. Bribery is a criminal offense; this includes bribery in business transactions as well as bribery of any holder of office. As a consequence, every direct or indirect offer, promise, provision, or acceptance of inappropriate benefits, whether material or of any other kind, for the purpose of acquiring orders or procuring unlawful advantages is forbidden to all employees.

1.2 Competition / prohibition of cartels

All employees must comply with legal regulations governing antitrust laws and business competition in each case. In particular, employees may not enter into or propose any agreement whatever as follows:
