TTM10110 - Ship Leasing: Defeased leasing

Meaning of 'defeasance'


As the owner of the leased asset, a finance lessor is normally entitled to claim capital allowances in respect of capital expenditure incurred in acquiring the asset.

However, a finance lessor will not be entitled to any capital allowances in respect of capital expenditure incurred on a qualifying ship provided to a tonnage tax company if the lease is defeased.


A lease will be regarded as defeased for this purpose if the leasing arrangements include provisions which have the effect of removing the whole (or the greater part) of any non-compliance risk which would otherwise fall (directly or indirectly) on the lessor.

For this purpose:

  • A ‘non-compliance risk’ means a risk that a loss will be sustained by any person if payments under the lease are not made in accordance with its terms.
  • The lessor and any persons connected with him are treated as the same person (and ‘connected person’ has the meaning given in ICTA/S839).

In practice, we regard ‘the greater part’ of the risk as having been removed if more than 50% of the risk has been removed by the defeasance arrangements

Excepted forms of security

When considering the extent of the lessor’s non-compliance risk for this purpose, certain forms of security may be disregarded. These are known as ‘excepted forms of security’, and they consist of:

  • certain parental or third party guarantees (see TTM10120), and
  • certain forms of security derived from the ship itself (see TTM10130).

There is no limit to the amount of ‘excepted security’ that can be provided in respect of a finance lease of a qualifying ship to a tonnage tax company.
