In a recent filing with the American Securities & Exchange Commission, the publisher noted that it paid $6 million to Relic's owners during the April to June quarter, with another $4 million due over the next two years.

As well as assuming Relic's debt of $517,000, that's $547,000 in tangible assets, $1.3 million in intangible assets, and a further $8.85 million in goodwill.

When it announced the purchase in April, THQ did not disclose the figure, but did reveal that the deal was for cash - a departure from the normal terms of such acquisitions. In general, publishers base developer acquisitions on shares, not cash.
