Optical Coating Laboratory Inc of Santa Rosa, California says it has instituted a voluntary redundancy programme and anticipates that it will reduce future payroll costs and enable organisational changes in both operations and support; the details of the programme are currently being developed, and costs to be absorbed in 1991 are not yet quantifiable; Optical says that the recent appointment of Herbert Dwight as chairman, president and chief executive officer, indicates that changes in direction and operations are appropriate; order rate has improved since the end of the third quarter, but it is still below expectations, and fourth quarter operating earnings before charges for the programme under consideration will be lower than the third quarter; Optical Coating says that charges for the redundancy programme will exceed fourth quarter profit and profit for the year will be below that for 1990.
