We have a zero-tolerance policy, we have anti-fraud committees, we have anti-fraud focal point in the camps, we have help line for refugees or anyone, you could get into our help line right now and report anything. These systems are very good, and they are working, i am not saying [ in ] this big organization, we are 100 % perfect. But we have measures in place, we have improved them in the last two years. But we can not exclude a case happening. And when a wrongdoing happens by our staff, they are disciplined, they are sanctioned and some staff( have) lost their job.
