 pictures has really increased compared to the past. Why is this happening and there's a frequent clients also frequently switching over their agencies. Why do you think believe this is happening? I don't know if they're more frequent than they used to be. I think there's a tenure of relationship. I think three years tends to be about the average amount. I think there are commercial pressures, macroeconomic pressures impacting the world economy and I think a lot of the costs are being passed down to consumers from clients business but it's right and proper that they should look across the entire supply chain that they employ and make sure that they're enjoying the most effective, not always the most efficient but the most effective relationships and I think that's where you have to get the balance right between cost efficiencies and effectiveness of delivery to grow the business. No one's ever going to cut themselves to growth so I think having a client that gets that balance right is important. I think one way of doing that is pitching. It doesn't always have to be I'm seeing more closed pitches where we're having conversations with clients about how we can support their business, how their business is evolving and therefore how our service to them needs to involve over the lifetime of the relationship.
