Business Combination Indemnification Assets Description	Since these amounts relate to tax periods prior to the combination, the Company expects that it would file an indemnification claim with Houghton’s former owners for any tax liabilities arising pre-Combination. As a result, a corresponding $4.0 million indemnification receivable has also been established through purchase accounting that would offset the $4.0 million in tax liabilities also booked through purchase accounting.
