M. Kevin McEvoy, chief executive officer of Oceaneering, stated, "Our fourth quarter operating results on an adjusted basis approximated our expectations and the consensus estimate. As industry conditions remained challenging, and our outlook for 2017 does not assume a pronounced recovery in demand for our services and products, our focus has been on organizing more effectively and managing our cost structure. Accordingly, these restructuring steps included a sizable reduction in our workforce. We made these difficult decisions to enable our organization to be leaner and appropriately sized for the expected level of business."
