Annex 2. Apportionment of capital cost (Article 5 refers)

1. General principles

The general principles adopted for the apportionment of the Capital Cost of the Project are as follows:

The Basic Cost (B) is established as the sum of the cost of dams at Driekoppies and Maguga which are of such sizes as only to firm up, to the levels of assurance as defined in Article 1, the water supply to consumers (irrigation, domestic, livestock, municipal, industrial and mining use) downstream of Vygeboom Dam on the Komati River and along the Lomati River as they existed in 1981 but under conditions of afforestation as it existed in 1978.

The Basic Cost is apportioned to Swaziland and South Africa in proportion to the mean basic water shortages experienced by the said consumers in each of the respective states in 1981 as set out in Section B.1 of Annex 3.

The Total Cost (T) is established as the sum of the cost of dams at Driekoppies (TD) and Maguga (TM) as constructed in the implementation of the Project.

The Basic Cost shall be fixed as 0.599 times the Total Cost.

The Incremental Cost (I) is established as the difference between the Total Cost and the Basic Cost. Hence the Incremental Cost shall be fixed as 0.401 times the Total Cost.

The Incremental Cost is apportioned to Swaziland and South Africa in proportion to the incremental water allocations expressed as equivalent High Assurance water as set out in Section B.2 of Annex 3.

2. Cost apportionment formulae

In the following formulae the following symbols are used in addition to those for costs given above:

3. Cost apportionment determination

For the purpose of cost apportionment, KOBWA shall prepare revised estimates of Total Cost (comprising separate estimates of the total cost of the Driekoppies and Maguga Dams) at least four months before the beginning of each financial year in accordance with the principles set out in Section 4 below.

Subject to the approval of the JWC, such estimates shall be used to determine the proportions referred to in Articles 5 (6) (b), 5 (6) (c) and 6 (3) in accordance with "the formulae set out in Section 2 above. Such proportions shall be used during the financial year in question to determine the payments due by the Parties to KOBWA in terms of Article 11 (3) (b).

Provided that from a date to be determined by the JWC following the completion of both Driekoppies and Maguga Dams, such proportions shall be set equal to those determined for the financial year in which such date falls and no further revision to Total Cost shall be made.

4. Principles for preparation of estimates of total cost

Estimates of the Total Cost shall be prepared in accordance with the following principles:

The Total Cost shall include all elements of cost identified as part of the Capital Cost in Article 5 except that the cost of financing shall be excluded.

All costs shall be expressed in South African Rand. If it becomes necessary to convert costs incurred in Swaziland Emalangeni to South African Rand at a rate other than parity, such cost shall be converted at a rate equal to the average of the means of the buying and selling spot rates quoted by The Standard Bank of South Africa and First National Bank for that amount at 11:00 two business days prior to transaction date.

Where costs are incurred in currencies other than South African Rand or Swaziland Emalangeni such costs shall be converted at the exchange rate applicable to the transaction.

All costs shall be adjusted to constant prices at the levels prevailing at a date approved by the JWC, utilising the cost escalation formula included in any applicable contract documents or, where no such formula is specified, by reference to an appropriate weighted selection from the following Price Indices for the Civil Engineering Industry published by the Central Statistical Service of the Republic of South Africa referenced as follows:

1. Labour index - weighted average
2.3 Civil engineering plant index (1981)
3.2 Civil engineering materials (1981)
4.1 Fuel index - diesel - coast

as approved by the JWC.

5. Worked example

The following worked example is provided for illustrative purposes only and is based on cost estimates prepared at September 1984 prices and on incremental water allocations given in Section B.2 of Annex 3:

Total Cost of Driekoppies Dam

TD

= R 104.7 million

Total Cost of Maguga Dam

TM

= R 138.3 million

Hence:

Total Cost

T

= R 243.0 million

South Africa: incremental water allocation

ir

= 111.0

Swaziland: incremental water allocation

is

= 72.6

Hence: Total incremental water allocation

= 183.6

Hence Swaziland's share of the Total Cost expressed as proportion of the cost of Maguga Dam is given by:

Ss

Accordingly South Africa's share of the Total Cost of Maguga Dam (1-Ss) is 0.60562.

[69Includes the evaporation losses from Shiyalongubo Dam, Which have not been qualified separately.]

A.3 CONVERSION FACTOR

The multiplication factor for converting water at Low Assurance to water at High Assurance stated in Article 12 (4) has been calculated as the ratio of the sum of the constant drafts70 from Driekoppies and Maguga Dams to the sum of the stepped drafts71 from Driekoppies and Maguga Dams operated independently of each other.

(70The constant draft used was that flow which can be abstracted from a dam at a uniform monthly rate throughout the simulation period without the dam failing in any one month.)

(71The stepped draft used was made up of two elements, the upper draft and the lower draft. The upper draft is a uniform monthly flow which can be abstracted from a dam at least 80% of the time on average (whenever the dam storage is above a particular rule curve). The lower draft is a uniform monthly flow which can be delivered throughout the remainder of the simulation period without the dam failing in any one month.)

The multiplication factor of 0.794 stated in Article 12 (4) is based on the assumption that the gross storage capacities, constant and stepped drafts are as follows:

A.4 TRANSMISSION LOSSES

Transmission losses are deemed to be the water released from Driekoppies and Maguga Dams for use other than the generation of hydro-electric power only plus the utilisable runoff downstream of the said dams minus Net Consumption downstream of the said dams.

The transmission loss allowance of 42 cubic hectometres per year at Low Assurance stated in Article 12 (5) (a) is a preliminary estimate which may be adjusted in accordance with the provisions of Article 12 (6).

A. 5 AFFORESTATION

The maximum areas of afforestation in hectares stated in Article 12 (8) have been derived as follows:

(72Areas based on afforestation permits issued between 1972 and 1981 but which had not been developed by 1978.)

The estimated mean gross water use of these areas of afforestation in terms of reduction of mean annual runoffis accepted to be as follows in cubic hectometres:
