For such purposes, "earnings" consist of earnings before taxes on income and fixed charges. "Fixed charges" consist of interest expense incurred on payables to customers, borrowings and one-third of rental expense, which is estimated to be representative of the interest factor. ** Because interest expense incurred in connection with payables to customers is completely offset by interest revenue on related investments and margin loans, the Company considers such interest to be an operating expense. Accordingly, the ratio of earnings to fixed charges excluding customer interest expense reflects the elimination of such interest expense as a fixed charge.
