[1] As discussed in Note 21, "Employee Benefit Plans," we elected to change our method of accounting for actuarial gains and losses for our pension plan in the United Kingdom to a more preferable method permitted under GAAP. We applied this accounting change retrospectively to all periods presented on the noted line items.

[2] Amount rounds to zero.
