Key legal question
Whether the cantonal court arbitrarily calculated the husband's income by annualizing a bonus paid only every three years.
Extracted holding
The bonus was indeed incorrectly annualized, but the error had no impact on the result and therefore did not make the decision arbitrary.
Extracted reasoning
Even though the court divided a trisannual bonus by twelve, the maintenance outcome remained unchanged because the wife's needs and the husband's available income still justified the ordered contribution.
