We determine the allowance requirement, on an account by account basis, by calculating an estimated financial risk for each OEM customer or distributor and taking into account other available information that indicates that receivable balances may not be fully collectible. Account balances are charged off against the allowance when it is probable that the receivable will not be recovered.

We sell our products to OEMs and to electronic components distributors who resell these products to OEMs, or their subcontract manufacturers. Net sales by customer type and net sales to significant customers were as follows:
