"12. Consequently it cannot be said that there is a transfer of an enterprise, business or part of part of a business on the sole ground that its assets have been sold. On the contrary, in the case like the present, it is necessary to determine whether what has been sold is an economic entity, which is still in existence, and this will be apparent from the fact that its operation is actually being continued or has been taken over by the new employer, with the same economic or similar activities. 13. To decide whether these conditions are fulfilled it is necessary to take account of all the factual circumstances of the transaction in question, including the type of undertaking or business in question, the transfer or otherwise of a tangible asset such as buildings and stocks, the value of intangible assets at the date of transfer , whether the majority of the staff was taken over by the new employer, the transfer or otherwise of a circle of customers and the degree of similarity between activities before and after the transfer and the duration of any interruption in those activities. It should be made clear, however, that each of these factors is only a part of the overall assessment which is required and therefore they cannot be examined independently of each other."
"There is nothing in any European decision to suggest that an economic entity ceases to retain its identity merely because the economic activity is subsumed into the transferee's business."
