What is intraperiod tax allocation and why does it matter for EPS analysis?

Intraperiod tax allocation (ASC 740-20) assigns total period tax expense among continuing operations, discontinued operations, OCI, and equity items so each component is presented net of its related tax. The general rule: tax on continuing operations is computed as if it were the only item, then residual tax is allocated to the other components. This 'incremental approach' prevents distortion of the continuing-ops ETR by discrete items.

For Nimbarro, assume 25% rate on each bucket in isolation. Step 1: compute tax on continuing ops standalone — $120M × 25% = $30M expense. Step 2: allocate remaining −$10M to the other items. Discontinued ops: ($40M) × 25% = ($10M) benefit. OCI: $25M × 25% = $6.25M expense, sits in OCI. Net effect on continuing-ops ETR: 30/120 = 25% (clean), not the blended 20/120 = 16.7% that would result without allocation.

Why it matters: (1) continuing-ops ETR is the one analysts model forward — intraperiod allocation keeps it representative of the recurring business; (2) discontinued ops and OCI items often have different effective rates (capital gains, foreign rates), and lumping them with continuing ops distorts trend analysis; (3) an exception exists — when there's a loss from continuing ops and gains in other components, tax is allocated to offset the continuing-ops loss first, which can produce a counterintuitive tax benefit on continuing ops despite positive consolidated earnings.
