1. 019How do you assess earnings quality?AccountingHardtechnicalMoody'sCorporate Finance · New York · 2018MorningstarEquity Research · Chicago · 2023

   Say this

   Compare earnings to cash. If net income is consistently above cash from operations, something is being recognised that has not been collected. Then check the accruals, the adjustments and the one-offs.

   Then walk it

   1. The headline test: cash conversion. Cash from operations divided by net income, tracked over several years. Persistent divergence is the single best red flag available from published accounts.
   2. Then working capital. Receivable days rising faster than revenue means revenue is being pushed to customers or collection is deteriorating. Inventory days rising means a write-down is coming.
   3. Then the adjustments. Compare GAAP to the company's adjusted figures and see what is being excluded. Restructuring charges taken every year for five years are not one-off, they are operating costs in disguise.
   4. Then capitalisation choices: capitalised development costs, capitalised interest, and the depreciation life. Extending useful lives flatters earnings with no economic change.
   5. Then the tax rate and the below-the-line items, since a sudden drop in the effective tax rate can manufacture an EPS beat.
   6. For a note, the useful summary is a bridge from reported earnings to what I think the sustainable earnings power is, with each adjustment listed. That bridge is often the most valuable page in a research report.

   Where candidates lose it

   Listing ratios without the organising idea. The organising idea is that accounting earnings involve judgement and cash does not, so every test is a version of comparing the two. Say that first.

   • What is the single best red flag?
   • How do you treat stock-based compensation?
   • Walk me through a company you thought had poor earnings quality.
