The starting point for the Top 1000 Companies 2020 list is the latest statutory fillings by companies in the Republic and Northern Ireland. Data is based on filings received by April 30th 2020.
Companies are ranked by turnover, apart from financial institutions which are ranked by assets and included in a separate table. Fund administration/management companies are shown separately at the bottom of this list.
Where turnover figures from the latest accounts were unclear, best efforts were made to ensure the most appropriate entry was taken.
Where companies filled consolidated accounts, the group turnover was taken.
The Irish subsidiaries of multinational or overseas companies are included if they are significant employers. If no financial information is available for the Irish operation, then turnover is estimated by The Irish Times on the basis of revenue per employee as per publicly available figures.
Turnover of betting firms such as Paddy Power and Boylesports etc is based on amount staked.
If a multinational has several subsidiaries in Ireland The Irish Times has, where possible, treated them as one entity grouped under the main Irish company. In some circumstances this was not possible and they appear separately.
Unlimited companies are included if they are judged by The Irish Times to carry out a significant level of economic activity in Ireland. Such companies have been asked to supply their turnover figures but where no figures are forthcoming, turnover has been estimated by The Irish Times. For example, the turnover of the larger retailers has been estimated on the basis of market share and total market size.
Turnover figures for law firms (with the exception of Mason Hayes+Curran) are based on estimated industry growth figures.
The following exclusions apply
External companies or companies with no Irish employees were excluded on the basis that their real level of economic activity in Ireland was small or impossible to measure.
Best efforts were made to avoid duplication of company entries, where subsidiaries and parent companies file individual and consolidated accounts.
In reading the tables please note the following
Where turnover has been estimated, it is indicated.
Where figures for profits or employees are not available the entry is left blank.
