R.S. 9:321 interim factors during litigation and La. R.S. 9:327 factors at final hearing. Maritime and hospitality overtime in the Port of New Orleans corridor should be annualized with employer schedules.
East Baton Rouge Parish capital-city government and LSU-affiliated pay cycles complicate earning-capacity arguments—attach HR step charts. Calcasieu Parish Lake Charles chemical-sector bonuses swing with plant turnarounds—use multi-year W-2 history before imputation hearings.

Caddo Parish Shreveport casino and logistics overtime should be annualized with employer HR schedules rather than peak-month pay stubs alone. Livingston Parish Denham Springs Baton Rouge exurban flood-insurance premium spikes may dominate needs arguments—attach NFIP declarations pages and elevation certificates.
Tangipahoa Parish Hammond I-12 distribution-center shift premiums should attach employer policy PDFs before hearings under La. R.S. 9:327. Vermilion Parish Abbeville rice and crawfish processing wages fluctuate seasonally—document cooperative and employer HR letters when modeling means.
