Goodwill and other acquisition-related intangibles.

Changes in goodwill as of September 30, 2011, by segment are as follows:

There was no impairment of goodwill during the nine months ended September 30, 2011. Goodwill in the Analog segment increased as a result of the National acquisition. The goodwill balances shown on our balance sheets are net of total accumulated amortization of $221 million.

The following table shows the components of acquisition-related intangible assets as of September 30, 2011 and December 31, 2010:
