Our Company
We are a full service, vertically integrated and self-administered REIT that owns, operates, acquires and develops high quality office,
retail, multifamily and mixed-use properties in attractive, high-barrier-to-entry markets in Southern California, Northern
California, Washington, Oregon, Texas and Hawaii. As of June 30, 2024, our portfolio was comprised of twelve retail shopping centers; twelve office properties; a mixed-use property consisting of a 369-room all-suite hotel and a retail shopping center; and six multifamily properties. Additionally, as of June 30, 2024, we owned land at three of our properties that we
classified as held for development and/or construction in progress. Our core markets include San Diego, California; the San Francisco Bay Area, California; Bellevue, Washington; Portland, Oregon and Oahu, Hawaii.
Our recently completed development and redevelopment projects include approximately 213,000 rentable square feet of office space at our La
Jolla Commons III property in the University Town Center area of San Diego, completed at the end of the first quarter of 2024. Additionally, we redeveloped approximately 100,000 rentable square feet of office space at our One Beach Street property
in San Francisco, which was completed in the third quarter of 2023. As of June 30, 2024 we had incurred $123.3 million in costs for the La Jolla Commons III development and $34.0 million in costs for the One Beach Street
redevelopment. Our total estimated investment for La Jolla Commons III and One Beach Street is $175.0 million and $42.8 million, respectively.
As of June 30, 2024, within our office portfolio (excluding La Jolla Commons III in San Diego, One Beach Street in San Francisco and
Eastgate in Bellevue/Seattle) in the San Diego market, San Francisco market and Bellevue/Seattle market, we had leased rates of 92.3%, 98.5% and 88.1%, respectively, and our average annualized base rent, or ABR, per leased square foot was $59.17,
$98.20 and $52.66, respectively. As of June 30, 2024, within our retail portfolio, we had a leased rate of 94.0% (excluding ground leases and including our Waikiki Beach Walk retail property) and average ABR per leased square foot of $31.56.
ABR is calculated by multiplying base rental payments (defined as cash base rents (before abatements)) under commenced leases for the month ended June 30, 2024, by 12. In the case of triple net or modified gross leases, ABR does not include
tenant reimbursements for real estate taxes, insurance, common area or other operating expenses. Other equity REITs may not calculate ABR as we do, and, accordingly, our ABR data may not be comparable to such other REITs ABR data.
