Fixed price contract is the contract in which the price is static throughout the contract period. A fixed-price contract may give certainty to budget and simplify contract management. However, it may lead to other problems since it requires bidders to estimate and bear the financial risks associated with price escalations. If the estimates are too high or events do not materialize, the buyer will pay a steep price that may affect the economy and efficiency of the contract. In the worst case, it may mean that the bid price is then above budget and may lead to a reduction in the requirements or rebidding. If the estimates are too low, it may appear as an abnormally low bid and disrupt contract execution.

On the other hand, price adjustment provisions include formulas designed to address problems, and can protect both the borrower and contractors from price fluctuations. Price adjustment formulas allow contractors to offer more realistic prices at the time of bidding. Despite concerns that they may lead to budget uncertainties, price adjustment formulas will estimate the actual cost implications that will be encountered. They use indexes that can be used for cost projection.

According to Asia Development Bank (ADB), any contract with a delivery or completion period beyond 18 months should contain an appropriate price adjustment clause.

In the scenario, the crude oil contract is planned to last 36 months. This period is pretty long with a fluctuating commodity. Therefore, the company should use price adjustment agreement.
