Estimated Mid Value £YY,000 EBIT £SY,000
Estimated Low Value £X,000 EBITDA £SSX,000

Liquidation Valuation

The liquidaton valuation values the company as if it were to cease trading and assets were subject to rapid disposal to cover liabilities. This valuation is primarily asset based.

Valuations Valuation Measures
