Griffin Capital Net Lease REIT Acquires Health Net of Californias Northern California Regional Headquarters for $22.65 million

El Segundo, Calif. (December 20, 2012) – Griffin Capital Corporation (“Griffin Capital”), on behalf of Griffin Capital Net Lease REIT, Inc., announced today the acquisition of a three‐story, approximately 146,000 square foot, 100% leased Class A office building (“Property”). Health Net of California, Inc., a leading managed healthcare provider with a stand‐alone, investment‐grade credit rating from Standard and Poor’s, occupies 97% of the building while the remaining 3% of the Property is leased to the Gold Pointe Corporate Center Association providing a café and fitness center, both welcome amenities for employees in the building and the office park. Health Net of California is a subsidiary of Health Net, Inc. and accounted for over 75% of the parent company’s revenues in 2011. Health Net, Inc. is a publicly traded company on the NYSE (ticker: HNT) and #221 on the Fortune 500 ranking of America’s largest corporations for 2012.

Originally developed in 2002 as a build‐to‐suit, the Property serves as the tenant’s primary Northern California commercial hub, and is home to a wide array of business functions including back‐office administration, and training and conferencing activities, as well as executive offices. Health Net of California executed a lease renewal in February 2012, extending its already decade‐long commitment to the site for an additional 10 years. Furthermore, the tenant has planned an additional $3.5 million in improvements, further solidifying their footprint and commitment to the property.

Situated in Rancho Cordova (approximately 20 miles east of Downtown Sacramento), which offers a deep pool of college‐educated residents and reasonable living costs, the location offers a cost‐effective alternative relative to higher‐priced locations such as the San Francisco Bay Area and Los Angeles. Further adding to the Property’s locational appeal is its access to and excellent visibility along Highway 50, which is one of the area’s primary east‐west freeways.

“The purchase price of $22.65 million, which represents a 9.08%1 initial capitalization rate on first year net operating income, affords our investors the ability to benefit from a healthy current risk‐adjusted return on an institutional quality office building long‐term leased to an investment‐grade rated tenant”, said Louis Sohn, Griffin Capital’s Senior Vice President of Acquisitions.

“We negotiated the price for this asset in May of 2012 and since then the Sacramento market has bounced off its bottom with five consecutive months of positive job growth, thus providing the REIT and our stockholders with what we believe to be an attractive entry point. Given that we have owned real estate in Sacramento for a prolonged period, we were able to utilize our extensive local contacts to recognize this positive trend early on and secure another institutional quality asset”, said Michael Escalante, Griffin Capital’s Chief Investment Officer. “The ability to add a core real estate asset, housing one of the country’s leading healthcare providers under a long‐duration lease and at an attractive initial yield to the REIT is highly consistent with our other acquisitions in 2012”, added Escalante.
