Several of our subsidiaries also sponsor defined contribution retirement plans, such as 401(k) or profit sharing plans.
Employee contributions to the plans are subject to regulatory limitations and the specific plan provisions. Several of the plans
provide that the subsidiary match these contributions up to levels specified in the plans and provide for additional discretionary
contributions as determined by management. Employer contributions expensed with respect to these plans were $637 million,
$572 million and $567 million for the years ending December 31, 2012, 2011 and 2010, respectively.
(21) Contingencies and Commitments
We are parties in a variety of legal actions arising out of the normal course of business. In particular, such legal actions
affect our insurance and reinsurance businesses. Such litigation generally seeks to establish liability directly through insurance
contracts or indirectly through reinsurance contracts issued by Berkshire subsidiaries. Plaintiffs occasionally seek punitive or
exemplary damages. We do not believe that such normal and routine litigation will have a material effect on our financial
condition or results of operations. Berkshire and certain of its subsidiaries are also involved in other kinds of legal actions, some
of which assert or may assert claims or seek to impose fines and penalties. We believe that any liability that may arise as a result
of other pending legal actions will not have a material effect on our consolidated financial condition or results of operations.
On February 13, 2013, Berkshire and an affiliate of the global investment firm 3G Capital (“3G”), through a newly formed
holding company (“Holdco”) entered into a definitive merger agreement to acquire H.J. Heinz Company (“Heinz”). Under the
terms of the agreement, Heinz shareholders will receive $72.50 in cash for each outstanding share of common stock
(approximately $23.25 billion in the aggregate.) Berkshire and 3G have committed to make equity investments in Holdco,
which together with debt financing to be obtained by Holdco will be used to acquire Heinz. Berkshire’s commitment is for the
purchase of $4.12 billion of Holdco common stock and $8 billion of its preferred stock that will pay a 9% dividend. 3G has
committed to purchase $4.12 billion of Holdco common stock. Berkshire and 3G will each possess a 50% voting interest in
