Announcement to NZX
Refining NZ Throughput and Margin Report for May/June 2018
Processing Fee income for the May/June period was NZD -2.8 million due to the impact of the May/ June
maintenance shutdown. Major refits were completed successfully during this one in fifteen year event and
position the refinery to capitalise on refining margins going forward. The refinery has been back in full
operation since 6 July.
Throughput for the May/June period was 3.9 million barrels. The Gross Refinery Margin
3)
(GRM) was USD -
0.71 per barrel for the period. The average exchange rate for the May/June period was USD/NZD 0.69.
The Singapore Dubai complex margin for the May/June period was USD 2.02 per barrel, down from
USD 3.75 per barrel margin for the March/April period.
Appendix I shows further information on throughput, margin and refining income.
Historical Analysis
A five year history of Throughput, Margins and Processing Fees is attached as Appendix II and can also be
found on the company’s website: www.refiningnz.com

Notes:
1. The information provided in this announcement relates to refining operations only. Revenue from pipeline or
other activities is not included.
2. The Processing Fee results reported in this announcement are subject to change due to post announcement
price updates and independent audit.
3. Refining NZ’s Gross Refining Margin is defined as the typical market value of the products produced minus the
typical market value of the feedstock used, expressed per barrel of feedstock used. The margin incorporates
the cost of the hydrocarbon used for fuel and incurred as process losses.

Explanatory Note
Throughput
Throughput is the volume of feedstock intake, comprising crude oil, residues, natural gas and blendstock,
measured in barrels. One barrel equates to approximately 159 litres.
Gross Refining Margin
The Gross Refining Margin is calculated in USD as the difference between the value of products and the cost
of feedstock for each refining customer. The value of products use Singapore quoted prices adjusted for
New Zealand quality and the cost of importing those products to New Zealand. Feedstocks are valued using
the notional market values adjusted for the cost of getting the feedstock to the refinery. The Gross Refining
Margin incorporates the cost of hydrocarbon used as fuel and incurred as process losses.
Typically, Refining NZ has an uplift over the Singapore complex margins of around USD 3.00 to 4.00 per
barrel. The value of the uplift varies due to fluctuations in freight rates, product quality premia, crude
market premia and operational performance. Product quality premia are the cost differentials between
products made to New Zealand quality and products made to the quality that applies to quoted prices in
Singapore. Crude market premia are the cost differences between the crude types actually processed at
Refining NZ and Dubai (used as basis for the Singapore complex margins).
Margin Cap/Fee Floor Adjustment
The processing agreements with our customers contain both Floor and Margin Cap clauses, both effective
over a full calendar year.
The Fee Floor is the minimum Processing Fee due, for a calendar year, up to a current maximum of NZD 134
million. If the year-to-date Processing Fee is below the pro-rata Fee Floor, then an interim pro-rata Fee
Floor payment is made by the Customers. Should the Processing Fee exceed the Fee Floor in future months
any pro-rata Fee Floor payments that have been made are repaid to the Customers.
The Margin Cap limits the Gross Refining Margin for each customer to a maximum of USD 9.00 per barrel
over the calendar year. Should the Gross Refining Margin fall below the Cap in future months any pro-rata
Cap reductions that have been made are repaid by the Customers.
The Cap and the Floor are subject to year-to-date adjustments.
Any balance remaining at the end of the year cannot be carried over to the next year.
Gross Refining Margin after Cap/Floor
The Gross Refining Margin adjusted for any impacts of the Cap or Floor.
Processing Fee
The Processing Fee is 70% of the Gross Refining Margin after any adjustment for the Cap or Floor. The
Processing Fee is paid by our customers in NZD.
