Equitable Life Assurance Society v Hyman [2002] 1 AC 408

The Equitable Life Assurance Society adopted a differential bonus policy for policyholders with guaranteed annuity rates (GARs), reducing final bonuses for those exercising their GAR rights. The House of Lords held this practice breached an implied term that directors could not exercise discretion to undermine contractual guarantees.

Facts

The Equitable Life Assurance Society, the oldest mutual life assurance society in the world, issued with-profits policies containing guaranteed annuity rates (GARs). When market annuity rates fell below the GARs from 1993 onwards, the Society’s directors adopted a differential bonus policy. This allocated different final bonuses to GAR policyholders depending on whether they elected to take the guaranteed annuity or take benefits in fund form at current rates. The purpose was to equalise total benefits regardless of which election the policyholder made, effectively neutralising the value of the guaranteed rates.

The Policies and Article 65

The Society’s constitution was contained in its memorandum and articles of association. Article 65(1) provided that directors ‘shall apportion the amount of such declared surplus by way of bonus among the holders of the participating policies on such principles, and by such methods, as they may from time to time determine.’ The Society argued this discretion was wide enough to permit the differential bonus policy.

Issues

The central issue was whether the Society was entitled to declare differential final bonuses to GAR policyholders depending on how they exercised their contractual rights, thereby undermining the value of the guaranteed annuity rates.

Judgment

The House of Lords unanimously dismissed the Society’s appeal. Lord Steyn delivered the leading judgment, holding that an implied term must be read into Article 65(1) precluding directors from exercising their discretion to override or undermine the guaranteed annuity rates.

Lord Steyn’s Reasoning

Lord Steyn explained the distinction between interpretation and implication:

The purpose of interpretation is to assign to the language of the text the most appropriate meaning which the words can legitimately bear.

He found that while Article 65(1) contained no express restriction, an implied term was strictly necessary:

The self-evident commercial object of the inclusion of guaranteed rates in the policy is to protect the policyholder against a fall in market annuity rates by ensuring that if the fall occurs he will be better off than he would have been with market rates.

Lord Steyn emphasised:

The supposition of the parties must be presumed to have been that the directors would not exercise their discretion in conflict with contractual rights.

Lord Cooke’s Reasoning

Lord Cooke of Thorndon reached the same conclusion by a complementary route, invoking the principle that:

no legal discretion, however widely worded… can be exercised for purposes contrary to those of the instrument by which it is conferred.

He observed:

The attractions of a GAR policy would be much diminished if it were explained that adverse discrimination in bonuses might be involved. A reasonable reader in the shoes of the policyholder would not understand this unless it had been clearly specified in the policy.

Ring-Fencing Issue

The House also rejected the suggestion that the Society could lawfully declare different bonuses based on whether policies contained GARs rather than on how benefits were taken, holding this would equally undermine the guarantees.

Implications

This decision is significant for several reasons. It establishes that discretionary powers in contracts must be exercised consistently with the reasonable expectations of the parties and cannot be used to undermine express contractual rights. The case demonstrates the court’s willingness to imply terms on grounds of strict necessity to give effect to the commercial purpose of contractual provisions. It also illustrates the convergence of public and private law principles regarding the exercise of discretionary powers.

Verdict: Appeal dismissed. The House of Lords held that the directors were not entitled to adopt a differential bonus policy that depended on how GAR policyholders exercised their contractual rights, as this breached an implied term in Article 65(1) precluding the directors from exercising their discretion to override or undermine the guaranteed annuity rates.
