Leading published run: claude-opus-4-8 (low reasoning) at 100.0% composite. Lowest: gpt-5.6-luna at 20.0%. 30 published runs shown on this task.

How this task was evaluated

Results are ordered by this task's published score. API runs use one prompt and one completion; agent runs use a coding harness with tools and iteration. Inspect the execution method when comparing results.

Objective scores use the benchmark's execution checks. Judge scores use a vision panel's fixed rubric; the published score leaves out a model's own family. Missing values are labelled rather than treated as zero.

Read the brief

This is a benchmarking hypothetical, not accounting advice. Figures are as at FY2025-26. A lessee enters a 5-year lease. The lease payment is $25,000 paid at the end of each year (5 payments in arrears). The interest rate implicit in the lease cannot be readily determined, so the lessee uses its incremental borrowing rate of 7% per year as the discount rate. There are no initial direct costs, no lease incentives, no prepaid lease payments, and no restoration costs. Under AASB 16: - the initial lease liability is the present value of the lease payments, discounted at 7%: Liability = sum over t = 1..5 of 25,000 / (1.07) ^ t - the right-of-use (ROU) asset, with none of the adjustments above, equals the initial lease liability. State, in dollars (round to the nearest cent): (a) the initial lease liability, and (b) the initial right-of-use asset. Name the accounting standard that governs this measurement.
