3-Statement Modeling: EBIT/EBITDA Reconciliation, Discontinued Ops, and Expense Detail

Hi everyone,

I’m building a 3-statement restructuring model and have a few income statement modeling questions:

1. EBIT / EBITDA
The annual report reports EBIT and EBITDA, but I can’t fully reconcile them from the underlying line items.
Is it better practice to hardcode them from the AR or calculate them in the model even if small differences remain?

2. Discontinued operations
In one year the income statement shows:

• Income from continuing operations before tax
• Income from continuing operations (net of tax)
• Income from discontinued operations (net of tax)

This breakdown does not appear in later years.
Should I keep the structure and assume discontinued ops = 0, or simplify the model to match later years?

3. Level of detail
Should items like Other income / Other expense and SG&A components be modeled separately as in the AR, or consolidated (e.g., net other income/expense, total SG&A)?

Thanks for any guidance.
