Calculate The Payback Period For Bethesda Mining's Project

Calculate the payback period for Bethesda Mining's project and analyze whether to proceed

Bethesda Mining Company, a mid-sized coal mining firm, is considering opening a new strip mine in Ohio to meet a contractual obligation from Mid-Ohio Electric Company. The project involves significant capital expenditure and operational considerations, including environmental reclamation costs and potential revenue streams. To evaluate whether Bethesda should proceed with the project, calculating the payback period provides a straightforward measure of how quickly the investment can be recovered from the project's cash flows. The payback period analysis helps the company determine the investment's risk and liquidity implications, critical factors when considering expansion projects that require sizable initial investments.

Given the detailed project parameters, including land valuation, equipment costs, production estimates, costs, revenues, and environmental obligations, the analysis involves estimating annual cash flows, accounting for taxes, working capital changes, and salvage values. This systematic approach ensures a comprehensive financial evaluation aligned with Bethesda's strategic decision-making framework.

Payback Period Analysis for Bethesda Mining's New Strip Mine

The payback period represents the time it takes for a project’s cumulative cash flows to equal the initial investment. To accurately calculate this, we first need to determine the project's expected annual cash flows, including revenues from coal sales, variable and fixed costs, changes in net working capital, tax implications, and salvage values at the end of the project.

Initial Investment Components

  • Land value (current appraisal): $7.3 million
  • Equipment purchase: $43 million
  • Net working capital (build-up before project starts): 5% of sales, with sales forecasted at 500,000 tons/year at $60/ton, totaling $30 million in sales annually; thus, NWC initial investment is 5% of $30 million = $1.5 million, to be invested prior to project commencement.
  • Land purchase cost (used for valuation): $5.4 million, but since the land can be sold for $7.3 million, this difference impacts the opportunity cost, but the primary investment is in equipment and NWC.

Given the focus on operational cash flows, initial outflows comprise the equipment cost ($43 million) and the initial NWC investment ($1.5 million). The land's market value provides an alternative scenario but does not represent a cash outflow if bought and held rather than sold immediately.

Annual Revenue and Operating Cash Flows

  • Coal sales from the contract: 500,000 tons/year at $60/ton = $30 million annually.
  • Spot market sales: excess production (production exceeding contract) sold at $48/ton. Using production estimates (750,000; 810,000; 830,000; 720,000 tons), the excess each year equals total production minus 500,000 tons.
  • Variable costs: $21/ton, fixed costs: $3.7 million/year.

The net revenue calculation subtracts variable costs and fixed costs from sales revenues. Taxes are then applied to determine after-tax cash flows, including depreciation benefits, considering the equipment's MACRS schedule and salvage value after four years.

Yearly Cash Flow Estimation

Assuming the production levels and sales, the estimated annual operational cash flows are calculated as follows:

  • Year 1 production: 750,000 tons; excess: 250,000 tons; Revenue: (500,000 x $60) + (250,000 x $48) = $30 million + $12 million = $42 million
  • Variable costs: 750,000 x $21 = $15.75 million
  • Spot market sales revenue: 250,000 x $48 = $12 million
  • Contribution margin: Revenue - Variable costs = $42 million - $15.75 million = $26.25 million
  • Fixed costs: $3.7 million annually.
  • Pre-tax cash flow: (Contribution margin - Fixed costs) = $22.55 million

Applying the 38% tax rate reduces pre-tax cash flow to after-tax cash flow, adding back non-cash depreciation deductions. For simplicity, the depreciation deduction on equipment (initially $43 million) on a MACRS schedule is computed, with salvage value included at the end of Year 4 (sale for 60%, i.e., $25.8 million). Land reclamation costs and donation expenses are accounted for in Year 5, but since they occur after the project’s payback period, their impact is more relevant when projecting total project viability over its entire lifecycle.

Calculating the Payback Period

In this analysis, the cumulative project cash flows are summed annually until they offset the initial investment of $43 million in equipment plus initial NWC investment of $1.5 million, totaling $44.5 million. The point at which accumulated cash flows equal or exceed this sum indicates the payback period.

Based on the estimated after-tax operating cash flows (~$16 million per year, after accounting for taxes and working capital adjustments), the project is expected to recover the initial investment approximately within 3 years. Precise calculations suggest that the cumulative cash flows will surpass the initial $44.5 million investment somewhere between Year 2 and Year 3, indicating a payback period of roughly 2.8 years.

Implications of the Payback Period on Decision-Making

Given the company's required return of 12%, a payback period of less than 3 years aligns with acceptable liquidity and risk management thresholds. Fast recovery of capital minimizes exposure to operational uncertainties and regulatory changes, making the project financially attractive under these parameters. Moreover, the relatively short payback period suggests a sound investment, especially considering the high-sulfur coal market's recent rebound due to technological advancements and increased demand.

However, the company must also consider secondary factors such as environmental costs, potential delays, and market fluctuations beyond the payback analysis. Nonetheless, from a purely financial perspective, the prompt recovery of capital indicates that Bethesda Mining should proceed with the project, assuming other strategic and regulatory considerations are favorable.

Conclusion

The payback period calculation reveals that Bethesda Mining can recover its initial investment—the equipment and working capital—within approximately 2.8 years. This financially favorable outcome, combined with the company's strategic capacity to meet contractual demand and capitalize on the rising coal market, supports proceeding with the strip mine project. Nevertheless, comprehensive due diligence, including risk assessments and sensitivity analyses, remains essential before final commitment.
