Vote “Yes” Today on SunCal’s Proposal to Acquire Westland Development.

A “Yes” Vote on the Westland Merger Will Allow the Atrisco Heritage to be Forever Preserved.

The Atrisco Land Grant site is so much more than mere acreage. It is also a collection of remarkable legacies that illustrate the great history of Spanish land grants and the establishment of Albuquerque, Bernalillo County and the American Old West.

SunCal is committed to honoring and protecting this heritage, and would contribute $1 million each year for the next 100 years to the Atrisco Heritage Foundation to preserve the significant cultural and historical resources of this property for future generations. Atrisco heirs would hold a majority of the seats on the Foundation’s Board of Trustees, which would have direct oversight of how the funds would be spent on important projects that may include museums, continuing education courses, cultural programs, daycare facilities, private schools and scholarships.

At the close of the merger, SunCal would pay the Foundation $2 million, representing the first two annual payments, allowing the Foundation’s Board of Trustees to begin work right away.

3 Reasons to Vote Yes

1. Atrisco Heritage Forever Preserved

2. $315 per share + oil, gas and mineral rights

3. Smart Growth for Albuquerque’s West Side

Any acquisition must be approved by a two-thirds vote of each class of Westland’s shares.
