In 2013, the Company changed the way of calculating employees severance liability to pro-rating the estimated ultimate discounted liability over the employee’s years of service instead of estimating the discounted liability as at the end of the year. The change resulted in decreasing the estimated liability at December 31, 2013 by Bht 69,797 when compared with the previous year. The Company believes that the new method gives a more reliable estimate of its liability for employees severance pay.
