Which contract type is typically used whenever the seller's performance period spans a considerable period of years?

Question

Options

• AFixed-Price-Incentive-Fee contracts (FPIF)
• BFixed Price with Economic Price Adjustment contracts (FP-EPA)
• CCost-Plus-Fixed-Fee contracts (CPFF)
• DTime and Material contracts (T&M)

• A
  13% (4)
• B
  75% (24)
• C
  3% (1)
• D
  9% (3)

Explanation

Fixed Price with Economic Price Adjustment (FP-EPA) is correct because multi-year contracts expose both buyer and seller to economic volatility - inflation, material cost shifts, labor rate changes - that can make a locked-in price unfair or unsustainable. The EPA clause ties price revisions to agreed-upon economic indices (e.g., CPI, commodity prices), protecting both parties across the extended performance period.

Why the distractors are wrong:

• A (FPIF): Incentive-fee structures motivate performance via profit/penalty sharing, but they don't address long-term price fluctuations - the base price stays fixed regardless of economic conditions.
• C (CPFF): Cost-plus contracts reimburse all allowable costs plus a fixed fee and are used when scope is uncertain - not because the performance period is long. They shift cost risk to the buyer entirely.
• D (T&M): Time-and-material contracts are best for undefined or short-duration work where labor hours and material costs can't be estimated upfront - not for structured multi-year efforts.

Memory tip: Think of the "E" in EPA as standing for Extended - whenever a contract is Extended over many years, you need an Economic Price Adjustment to keep it fair as the economy changes.
