From HM Revenue & Customs · Capital Gains Manual
TCGA92/S185 (3)
If a company which ceases to be resident
disposes of `old assets’ before it migrates,
acquires `new assets’ after it migrates
TCGA92/S185 (3) prevents it from rolling over the gains under the provisions of TCGA92/S152, see CG60250+. The restriction does not apply if the new assets are assets of a permanent establishment which are exempted from the exit charge by TCGA92/S185 (4), see CG61350.
