English to Spanish Bus/Financial Accounting

Hola a todos:
La palabra en conflicto es "walk", que siempre aparece combinada. Aquí va el contexto.

Margin **Walk** [title]
Margin variances from one period to another can be explained in many different ways:
Financial Accounting **Walk**
Business Segment **Walk**
Margin **Walk**
Variance Analysis Model generates **walks** & your job is to explain results

Cost **Walk** [title]
All changes in cost from one period to the next can be explained by a combination of changes in Volume, Inflation and Productivity (plus foreign exchange when converting currencies). This additive property is known as the Cost **Walk**.

No puedo encontrar el equivalente en español. ¿Alguna sugerencia?
¡Muchas gracias!
