🕰️ Background
Harnischfeger Industries (mining and construction equipment) changed several accounting policies simultaneously in 1984: lengthened depreciation lives, changed pension assumptions, reduced inventory reserves, and adopted more aggressive revenue recognition. Each change was individually disclosed and legal, but collectively they transformed a loss into a profit. The classic HBS case for understanding how accounting policy changes affect financial statements.
❓ The Central Problem
How do legitimate accounting policy changes affect the quality of reported earnings? The case requires students to identify each accounting change, quantify its impact on net income, and determine whether the reported profit is ‘real’ or manufactured through policy changes.
📊 Analysis
Detailed analysis of each policy change: (1) Depreciation: Extended useful lives → lower expense, (2) Pension: Increased assumed rate of return → lower pension cost, (3) Inventory: Reduced LIFO reserves → one-time gain, (4) Revenue recognition: More aggressive timing. Students must calculate that without these changes, Harnischfeger would have reported a loss. The reported profit was entirely an accounting artifact. Management’s argument: the company was genuinely improving, and the old policies were too conservative. Skeptics’ view: the changes were timed to coincide with a management buyout proposal.
🔑 Key Lessons
- Accounting policy changes can transform losses into profits without any change in underlying business performance
- Each individual change may be legitimate — the manipulation is in the timing and aggregation of multiple simultaneous changes
- Quality of earnings analysis requires stripping out the impact of policy changes to see ‘normalized’ performance
- Pro forma adjustments (adding back/removing one-time items) are the analyst’s primary tool for assessing earnings quality
🎓 Discussion Questions
- Recalculate Harnischfeger’s earnings WITHOUT the accounting changes. What would the ‘true’ result have been?
- Is it appropriate for management to change 4-5 accounting policies simultaneously? When might this be legitimate?
- How should analysts adjust for accounting policy changes when comparing performance across years?
