Freeze and Growth Reorganisations: The UK Guide

What is a freeze and growth reorganisation?

A freeze and growth reorganisation is a UK corporate restructuring used to fix ("freeze") the existing value of a company in the hands of the current shareholders, and to channel future growth into a new class of shares - typically held by the next generation, by management, or by a family trust. The frozen interest crystallises the value built up to date; the growth interest captures everything from that point forward.

It is one of the most widely used succession-planning tools for UK owner-managed businesses, and a central topic in family-business and tax planning. Done well, it transfers future value efficiently with controlled tax exposure and without disrupting day-to-day operations. Done poorly, it triggers immediate income tax, employer NICs and inheritance tax charges that wipe out the planning benefit.

The reorganisation rests on a precise share-class design and on a defensible market-value valuation of the company at the freeze date - which is why it is a recurring engagement for UK valuation practices.

Why owners use a freeze structure

Most freeze-and-growth structures are motivated by one of four objectives:

• Inheritance tax planning. The senior generation's value is fixed in a frozen class; future growth accrues outside their estate, typically to children, grandchildren or a discretionary trust.
• Management incentivisation. Future value is allocated to a growth class held by the management team, providing equity upside without altering current ownership of past value.
• Generational succession. The founder retains income and control through preferred or voting shares; operating successors take the growth class.
• Pre-sale planning ahead of an eventual exit. A multi-year horizon allows growth-class holders to participate in the upside of the eventual sale at materially lower tax cost than direct gifts of existing shares.

The common thread is that current value belongs to one group, and future value belongs to another - and the structure makes the split legally clean.

How the structure works

A typical UK freeze and growth reorganisation involves the following steps, usually in the same transaction:

1. Valuation of the company at the freeze date. This establishes the floor or "hurdle" that the growth class must exceed before participating in equity value.

2. Share reorganisation under the Companies Act 2006. Existing ordinary shares are converted or sub-divided into a new class - typically *frozen* shares - with rights designed to capture the value as at that date.

3. Creation of a new growth share class. New shares are issued whose entitlement on a sale, winding-up or dividend is limited to value *above* the hurdle.

4. Allocation of the growth shares. Subscribed for by the chosen recipients - children, trust, management team - at market value (which, by design, is low if the hurdle is set correctly).

5. Tax clearances. HMRC clearances are commonly sought under section 138 TCGA 1992 (share reorganisations) and section 701 ITA 2007 (anti-avoidance), confirming the steps are commercial and not tax-driven.

6. Documentation refresh. Articles, shareholders' agreement and any option plans are updated to reflect the new class structure.

The legal mechanism varies. Some reorganisations use a rights variation within the existing company; others use a fresh holding-company insertion under a section 110 IA 1986 or section 136 TCGA 1992 structure. The substance is the same: existing value sits in one class; future value sits in another.

The role of valuation

The freeze date valuation is the cornerstone of the whole structure. It performs three functions simultaneously:

• Sets the hurdle. The growth class is entitled to value above an agreed reference figure. That figure has to be the market value of the company on the freeze date.
• Establishes the AMV of the growth shares. If the structure is well-designed, the hurdle equals or exceeds market value, so the growth shares have a *low but non-trivial* market value at issue - typically a few percent of the underlying enterprise value, reflecting the option-like nature of the growth class.
• Provides the HMRC evidence base. If the recipient is an employee or director, the issue is an employment-related security and the valuation underpins both the AMV used for tax purposes and the UMV used for the section 431 election.

A defensible report sets out enterprise value, equity value, the hurdle proposed, the rights of the new class, and the implied market value of a growth share. UK practice typically uses a combination of earnings-multiple analysis for the hurdle and an option-pricing model (Black-Scholes or a binomial lattice) for the growth share itself.

Designing the hurdle

The hurdle is the value above which the growth shares participate. It is the single most consequential design decision.

• Hurdle equals current market value. The conservative default. Growth shares carry only future value; their market value at issue is low but positive (the option value over the hurdle).
• Hurdle above current market value. A "ratchet" structure where the growth class only participates above an enhanced threshold. Pushes the AMV of the growth shares even lower but reduces participation if the company underperforms expectations.
• Hurdle below current market value. Avoided in employment-related-securities contexts because it gives the holder immediate value, which is an income tax event on day one.

The hurdle is normally expressed as a fixed cash amount (the agreed enterprise or equity value at the freeze date), sometimes with a coupon (a 5%-8% annual accretion to reflect time value).

The frozen class

The frozen shares typically have:

• A fixed preferred return on a sale or winding-up equal to the hurdle, sometimes with an annual coupon.
• Voting rights retained where the senior generation wants to keep control.
• Dividend rights sized to match the holder's income objectives.
• Limited or no participation in growth above the hurdle.

Because the frozen class has a defined economic ceiling, its value can only fall or stay flat in real terms. That is the engine of the IHT planning - the senior generation's estate is capped at the hurdle plus accrued coupon.

The growth class

The growth shares typically have:

• No participation up to the hurdle. Zero economic entitlement on a sub-hurdle exit.
• Pro-rata participation above the hurdle, often alongside the frozen class on a defined waterfall.
• Limited or no voting rights. Where management is the recipient, control stays with the founders.
• Restrictions on transfer. Pre-emption, good/bad leaver provisions where management holds the shares, family-only transfer windows where children or trustees hold them.

The growth class is conceptually an option on enterprise value above the hurdle. That is why option-pricing models feature prominently in growth-share valuations.

Tax treatment

The treatment depends on who holds the growth shares and how they were acquired.

• Family members or trusts (non-employees). No employment-related-securities issue. The acquisition is a chargeable event under the gift-on-incorporation or section 138 clearance route; CGT and IHT analysis dominates.
• Employees and directors. Employment-related securities apply. The growth shares are typically restricted (good leaver / bad leaver, pre-emption), so AMV and UMV diverge. A section 431 election is normally made within 14 days to lock the income-tax event at acquisition and shift all future growth into CGT.
• Hold-over and gift relief. Section 165 TCGA 1992 hold-over relief may apply on gifts of business shares between non-corporate persons, deferring the CGT charge.
• Business Property Relief. Most trading-company growth shares qualify for BPR after the standard two-year holding period, protecting the value against IHT on a later death.

A well-designed freeze structure typically combines section 431 elections, section 138 clearance, section 701 confirmation and Business Property Relief planning into a single coherent package.

What HMRC looks for

The reorganisation faces scrutiny from three HMRC angles:

• Shares and Assets Valuation. Reviews the freeze-date valuation, the hurdle, and the AMV/UMV of the growth shares. SAV expects to see a clearly-evidenced enterprise value, a well-explained option-pricing analysis for the growth shares, and a properly-completed Form 42 / ERS return where relevant.
• Section 701 ITA 2007 anti-avoidance. Tests whether the transaction in securities has a commercial purpose. Clearance under section 701 is routinely sought and routinely granted where the structure has a real succession or management-incentive purpose.
• General anti-abuse rule (GAAR). A backstop, rarely triggered for a freeze structure that follows established practice. The risk increases where the hurdle is artificially low, the recipients are wholly artificial entities, or the transaction is paired with immediate cash extraction.

The combination of formal clearances and a defensible valuation is the standard protection.

Worked example

The owner of a UK trading group, valued at £10m equity value, is in her early sixties and wants to step back over five years while bringing her two children into ownership. Both children are active in the business.

A freeze and growth reorganisation is undertaken:

• Freeze date valuation. Equity value agreed at £10m. The owner's existing 100 ordinary shares are converted into 100 frozen shares with a £10m preferred return on a sale or winding-up, a 5% annual coupon, and full voting rights for the first five years.
• Growth class. 100 new growth shares are created, with no participation up to the £10m hurdle plus accrued coupon, then pro-rata participation alongside the frozen class. 50 are issued to each child.
• Valuation of the growth shares. Using a Black-Scholes analysis with a 25% volatility assumption, a five-year horizon and a risk-free rate of 4%, the option value of a growth share is calculated at approximately £18,000 per share. Total subscription cost: £1.8m.
• Funding. The children fund the subscription through a personal loan from the company, repayable over five years from dividends declared on a small participating right attached to their growth shares.
• Tax. Both children are directors. A section 431 election is filed within 14 days. Section 138 and section 701 clearances are obtained in advance.

Five years later the business is sold for £18m. The frozen class receives £10m plus accrued coupon (approximately £12.8m). The growth class receives the residual approximately £5.2m, split between the children. Their capital gain is taxed at CGT rates, with full BADR available subject to the eligibility tests, rather than at income tax rates.

The estate of the owner is capped at the value of the frozen class - approximately £12.8m - rather than the full £18m enterprise value, with a corresponding IHT saving of several hundred thousand pounds on a later chargeable event.

When a freeze is and is not appropriate

A freeze and growth structure works well when:

• The owner is prepared to cap their participation in future value.
• The next generation or management team is genuinely able to drive the growth that will be captured by the growth class.
• The business has a realistic five-to-ten year value-creation runway.
• A future exit, refinancing or generational handover is plausible.

It is not appropriate where:

• The owner expects to remain the principal value-creator indefinitely.
• The business is mature or declining, with limited future growth to allocate.
• A near-term sale is in contemplation - the growth class then has substantial day-one value, increasing the acquisition cost and the income-tax risk.
• The shareholder register is already too fragmented to support a clean restructuring.
