Political Action Committee

To give you a voice in Washington, the IATSE has established the IATSE
Political Action Committee ("IATSE-PAC"), a federal political action
committee designed to support candidates for federal office who promote the
interests of the members of IATSE locals and to support a federal
legislative and administrative agenda to benefit those members.

Members of the IATSE locals, and their families, may contribute to the
IATSE-PAC. All contributions to the IATSE-PAC are voluntary, and are not
tax-deductible. The amount contributed, or the decision not to contribute,
will not be the basis for the IATSE or any of its locals to benefit or
disadvantage the member or his/her family. Neither the IATSE nor any of its
locals will retaliate against a member for deciding not to contribute, or
based upon the amount of the contribution.

Contribution amounts are suggestions only, and you may contribute more or
less than the suggested amount. A person's contribution to the IATSE-PAC may
not exceed $5,000.00 per year. Contributors must be United States citizens
or lawful permanent residents of the United States. The IATSE-PAC may not
accept contributions from corporate accounts.
