We base our corporate principles on the philosophy of Integrity-Safety-Quality-Output (ISQO). This is symbolized by a mark representing a single tree, which helps our employees understand the concept of ISQO.
“Integrity” represents good soil, which is essential to allow the buds of “Safety” and “Quality” to grow and develop into leaves, which become part of a healthy tree that bears plenty of fruit (“Output”).  All of our employees work with the ISQO philosophy in mind thanks to its distinctive symbol and simple name.
