And if from the bottom it's either yours or it's theirs. THE WITNESS: On Figure 1 the Langan model is on the top and the Princeton Hydro model is on the bottom. That is correct. They both reflect that. If I had misspoke and reversed that I apologize but that's -- CHAIRMAN BAGOFF: Thank you. THE WITNESS: Regardless it makes no difference because we basically replicated their model and we came up with the same number because we used their parameters that they assumed based on test rock information. And the same thing on Page 3. We also came up with similar factors of safety regarding the model. Ours -- theirs was on top and ours was on the bottom. So we came up with a factor of safety of 1.938 and they came factor of safety of 1.36. So I thank you for that correction if I had reversed that. MR. AFRAN: Mr. Goll, I have a couple quick questions for you. When you said the numbers were basically the same, you're referring on Page 2 of your report to the fact that the Langan number was 1.589 and yours was 1.599, is that correct?
