The group provides benefits for all its permanent employees through the Telkom Pension Fund and the Telkom Retirement Fund. Membership of one of the funds is compulsory. In addition, certain retired employees receive medical aid benefits and a telephone rebate. The liabilities for all of the benefits are actuarially determined in accordance with accounting requirements each year. In addition, statutory funding valuations for the retirement and pension funds are performed at intervals not exceeding three years.

Actuarial valuations were performed by qualified actuaries to determine the benefit obligation, plan asset and service costs for the pension and retirement funds for each of the financial periods presented.

Telkom Pension Fund

The Telkom Pension Fund is a defined benefit fund that was created in terms of the Post Office Amendment Act 85 of 1991. The Telkom Pension Fund consists only of active members.

The latest actuarial valuation performed at 31 March 2015 indicates that the pension fund is in a surplus position of R180 million (2014: R180 million). The recognition of the surplus is limited due to the application of the asset limitation criteria in IAS19 Employee Benefits. The Telkom Pension Fund is closed to new members. The pension plan exposes the group to actuarial risks, such as longevity risk, currency risk, interest rate risk and market risk.

The funded status of the Telkom Pension Fund is disclosed below.

Funding arrangements

The Telkom Pension Fund investment strategy has been implemented through the appointment of two asset managers with global balanced mandates. Within these mandates the manager is responsible for and has sole discretion of determining the asset allocation, i.e. the mix of the various asset classes used, based on their investment views. In addition a small additional allocation to a specialist manager in the Africa Equity and SA Cash asset classes was added to further diversify the portfolio and to provide return enhancement. The Telkom Pension Fund's total asset allocation is thus derived by combining the two balanced asset managers' portfolios with the Africa and additional cash allocation.

The Telkom Retirement Fund

The Telkom Retirement Fund was established on 1 July 1995 as a hybrid defined benefit and defined contribution plan. Existing employees were given the option to either remain in the Telkom Pension Fund or to be transferred to the Telkom Retirement Fund. All pensioners of the Telkom Pension Fund and employees who retired after 1 July 1995 were transferred to the Telkom Retirement Fund. Upon transfer the government ceased to guarantee the deficit in the Telkom Retirement Fund. Subsequent to 1 July 1995 further transfers of existing employees occurred. As from 1 September 2009 all new appointments will belong to the Telkom Retirement Fund but will not be able to retire from the Telkom Retirement Fund at retirement age. These members would be required to purchase their pensions from an insurance company.

The Telkom Retirement Fund is a defined contribution plan with regards to in-service members. On retirement, an employee is transferred from the defined contribution plan to a defined benefit plan. Telkom, as a guarantor, is contingently liable for any deficit in the Telkom Retirement Fund. Moreover, all of the assets in the Fund, including any potential excess, belong to the participants of the scheme. Telkom is unable to benefit from the excess, in the form of future reduced contributions. The pensioner pool of the Telkom Retirement Fund only consists of pensioners and is funded through a liability driven investment strategy (LDI). Pensioner increases are subject to affordability targeting between 70% and 100% of CPI.

Telkom guarantees any actuarial shortfall of the pensioner pool in the retirement fund. This liability is initially funded through assets of the retirement fund.

The Telkom Retirement Fund is governed by the Pension Funds Act 24 of 1956. In terms of section 37A of this Act, the pension benefits payable to the pensioners cannot be reduced. If therefore the present value of the funded obligation were to exceed the fair value of plan assets, Telkom would be required to fund the statutory deficit.

Funding arrangements

The Telkom Retirement Fund pensioner portfolio's strategic asset allocation (SAA) is determined by an asset liability model (ALM) based on the Fund's unique liabilities, as determined by its member data and Fund rules. The SAA is a reflection of the Fund's targeted post-retirement interest rate (PRI), and the investment strategy is built around the target of providing consistent annual pension increases of between 70% and 100% of CPI.

Medical benefits

Telkom makes certain contributions to medical funds in respect of current and retired employees. The scheme is a defined benefit plan. The expense in respect of current employees’ medical aid is disclosed in note 6.3. The amounts due in respect of post-retirement medical benefits to current and retired employees have been actuarially determined and provided for as set out in  note 29. Telkom has terminated future post-retirement medical benefits in respect of employees joining after 1 July 2000.

There are three major categories of members entitled to the post-retirement medical aid: pensioners who retired before 1994 (‘Pre-94’); those who retired after 2013; and the in-service members. The pensioners retiring post 2013 and the in-service members’ liability are subject to a rand cap, which increases as per board approval. During the current financial year the group settled its obligation with the post-1994 pensioners.

Eligible employees must be employed by Telkom until retirement age to qualify for the post-retirement medical aid benefit. The most recent actuarial valuation of the benefit was performed as at 31 March 2015.

Telkom has allocated certain investments to fund this liability as set out in note 16.2. The annuity policy of the cell captive investment is the medical plan asset. The group is entitled to a refund of the full surplus in the annuity policy once all the beneficiaries have been paid. As such the group has recognised the full asset.

Telkom employee share plan

Telkom's shareholders approved the Telkom Forfeitable Share Plan (FSP) and the Additional Share Award (ASA) at the September 2013 Annual General Meeting. Two grants have occurred under this plan at 31 March 2015

The FSP is made up of Long Term Incentive Scheme (LTIP) and the Employee Share Ownership Plan (ESOP). In the FSP employees acquire shareholder rights immediately on the forfeitable shares (these include dividends and voting rights).

The ASA scheme is awarded to eligible participating members.This scheme is only applicable for the first grant of shares. If all conditions are met, the shares on this scheme will vest in the 2017 financial year.

The grant and vesting timelines for the LTIP are as follows:

Vesting financial year     Grant financial year
      2014   2015   2016  
2017 Financial Year     50%   –   –  
2018 Financial Year     30%   50%   –  
2019 Financial Year     20%   30%   50%  
2020 Financial Year     –   20%   30%  
2021 Financial Year     –   –   20%  

The grant and vesting timelines for the ESOP are as follows:

Vesting financial year     Grant financial year
      2014   2015   2016  
2017 Financial Year     100%   –   –  
2018 Financial Year     –   100%   –  
2019 Financial Year     –   –   100%  

In order for the vesting to occur the targets (including performance conditions) must be met. The targets are measured in each financial year after the grant date. In calculating the expense it is assumed that the probability of meeting the conditions is 100%.

The weighted average remaining vesting period for the shares outstanding as at 31 March 2015 is 2.8 years (2014: 2.8 years).

The following table illustrates the movement of the maximum number of shares that were granted to employees for the 2014 and 2015 grant:                          
Beginning of the year       7 101 388   –       7 101 388   –  
Forfeited shares during the year       (1 036 691)   –       (1 036 691)   –  
Granted during the year       4 872 132   7 101 388       4 872 132   7 101 388  
Outstanding at end of the year       10 936 829   7 101 388       10 936 829   7 101 388  
The fair value of the shares granted has been calculated by an actuary using the Black-Scholes-Merton model and the following values at grant date:       Grant 2   Grant 1       Grant 2   Grant 1  
Market share price (R)       76.11   27.30       76.11   27.30  
Dividend yield (%)       –   –       –   –  
Share price volatility       35% p.a   35% p.a       35% p.a   35% p.a  
Future risk free interest rate       6.7% p.a   8.5% p.a       6.7% p.a   8.5% p.a  
The principal assumptions used in calculating the expected number of shares that will vest are as follows:                          
Employee turnover (%)       3.3   3       3.3   3  
Meeting specified performance criteria (%)       100   100       100   100  

The key performance indicators for the first grant are free cash flow targets and net promoter score targets. The second grant key indicators are headline earnings per share, free cash flow, return on equity, total shareholder return, customer loyalty measure and assurance and fulfilment measures.
