Is it permissible for an employee to use the surplus of the food provisions supplied by the company in his home?

If the materials disbursed by the company to employees are for ownership, then it is permissible for them to take the excess to their homes, especially if it cannot be returned, because that would be a waste of money. However, if the materials are for use only within the company and the company does not allow them to be taken, then it is not permissible for employees to take them to their homes. The officials should be asked to ascertain the truth of the matter.
