The Brett Martin group is headquartered in Newtownabbey.
The principal activities of the group are the manufacture of glassfibre thermoplastic sheeting and pipes - products which are frequently used in construction and drainage contracts.
Other subsidiaries of the group are based in Great Britain and the Netherlands. A large proportion of production is exported.
The group increased annual turnover in the early years of the previous decade, reaching a peak of £112m in 2007.
Then for two successive years turnover fell slightly to £101m in 2009.
More recently, turnover has recovered to reach a new high of £124m in 2011.
Operating profits also peaked in 2007 at £7.8m but were lower in the following years, stabilising at near to £3m in 2010 and 2011.
A similar trend is reflected in changes in pre-tax profits.
After a sharp fall in profits in 2008, despite the adverse general market conditions, operating and pre-tax profits have recovered in 2009-11.
Dividend payments to shareholders have averaged about £2m annually in recent years. However, in 2011 they were reduced to £1.5m.
Employment in the group has varied slightly from year to year.
In 2009, numbers employed fell by 9% to average just 737 people and then recovered in 2010 and averaged 774 people in 2011.
The balance sheet value of shareholders' funds at just over £33m has varied slightly, usually influenced by the combined impact of post-tax profits and after allowing for the deduction of dividends.
The directors report that they are committed to creating long-term shareholder value by increasing market share through a combination of organic growth and acquisitions.
They further report that they are satisfied with the level of growth and the overall results and are confident that trading margins will increase during 2012.
