The GE Finance subsidiary that invested in the portfolio is Intramerica Real Estate Group. The joint venture is called Intramerica Industrial Properties I. The portfolio has a 95% occupancy rate and consists of mostly tilt-wall industrial buildings built out specifically for certain international manufacturers, and developable land, according to the source. Geographically, the properties are spread out between central, coastal and US border cities.

"Many of them are labor-intensive and capital intensive operations such as Plastic injection molding and metal stamping that require high electric loads," according to the source. "Some of the properties date back to the Arguelles family start in the business in 1977."

At lease half of the portfolio was amassed by the Arguelles family through a partnership with AIG Global Real Estate Investment Corp. that began in 2000 and included AIG-GREIC buying a stake in FINSA. The Argelles family will use some of the net proceeds to launch a new partnership with AIG-GREIC called FINSA II. The joint venture will start with $100 million of equity, which will be used to develop at least 10 million sf of new industrial real estate in Mexico using FINSA´s available land bank and future new land acquisitions.
