Mixed-Use Portfolio

Multifamily Portfolio

(1)Annualized base rent is calculated by multiplying base rental payments (defined as cash base rents (before abatements)) under commenced leases for the month ended December 31, 2023 by 12. In the case of triple net or modified gross leases, annualized base rent does not include tenant reimbursements for real estate taxes, insurance, common area or other operating expenses. The foregoing notwithstanding:

a. The annualized base rent for La Jolla Commons has been adjusted for this presentation to reflect that the contractual triple net leases were instead structured as modified gross leases, by adding the contractual annualized triple net base rent of $35,743,797 to our estimate of annual triple net operating expenses of $10,507,904 for an estimated annualized base rent on a modified gross lease basis of $46,251,701 for La Jolla Commons.

b. The annualized base rent for Eastgate Office Park has been adjusted for this presentation to reflect that the contractual triple net leases were instead structured as modified gross leases, by adding the contractual annualized triple net base rent of $4,656,039 to our estimate of annual triple net operating expenses of $1,819,424 for an estimated annualized base rent on a modified gross lease basis of $6,475,463 for Eastgate Office Park.

c. The annualized base rent for Corporate Campus East III has been adjusted for this presentation to reflect that the contractual triple net leases were instead structured as modified gross leases, by adding the contractual annualized triple net base rent of $4,508,259 to our estimate of annual triple net operating expenses of $1,745,372 for an estimated annualized base rent on a modified gross lease basis of $6,253,631 for Corporate Campus East III.

d. The annualized base rent for Bel-Spring 520 has been adjusted for this presentation to reflect that the contractual triple net leases were instead structured as modified gross leases, by adding the contractual annualized triple net base rent of $2,140,936 to our estimate of annual triple net operating expenses of $848,087 for an estimated annualized base rent on a modified gross lease basis of $2,989,023 for Bel-Spring 520.

(2)This property contains 422,426 net rentable square feet consisting of The Landmark at One Market (378,206 net rentable square feet) as well as a separate long-term leasehold interest in approximately 44,220 net rentable square feet of space located in an adjacent six-story leasehold known as the Annex. We currently lease the Annex from an affiliate of the Paramount Group pursuant to a long-term master lease effective through June 30, 2026, which we have the option to extend until 2031 pursuant to one remaining five-year extension option.

(3)Lease data for signed but not commenced leases as of December 31, 2023 is in the following table:

(a) Office portfolio leases signed but not commenced of 7,016 and 7,198 square feet are expected to commence during the first and second quarters of 2024, respectively. Retail portfolio leases signed but not commenced of 3,264, 1,200, and 27,037 square feet are expected to commence during the first, second and third quarters of 2024, respectively.

(b) Annualized base rent is calculated by multiplying base rental payments (defined as cash base rents (before abatements)) for signed but not commenced leases as of December 31, 2023 by 12. In the case of triple net or modified gross leases, annualized base rent does not include tenant reimbursements for real estate taxes, insurance, common area or other operating expenses. Annualized base rent per leased square foot is calculated by dividing annualized base rent, by square footage for signed by not commenced leases.

(c) Pro forma annualized base rent is calculated by dividing annualized base rent for commenced leases and for signed but not commenced leases as of December 31, 2023, by square footage under lease as of December 31, 2023.

(4)Net rentable square feet at certain of our retail properties includes square footage leased pursuant to ground leases, as described in the following table:

(5)The Hassalo on Eighth property is comprised of three multifamily buildings, each with a ground floor retail component: Velomor, Aster Tower and Elwood.

(6)The Santa Fe Park RV Resort is subject to seasonal variation, with higher rates of occupancy occurring during the summer months. The number of units at the Santa Fe Park RV Resort includes 120 RV spaces and four apartments.

In the tables above:

•The net rentable square feet for each of our retail properties and the retail portion of our mixed-use property is the sum of (1) the square footages of existing leases, plus (2) for available space, the field-verified square footage. The net rentable square feet for each of our office properties is the sum of (a) the square footages of existing leases, plus (b) for available space, management's estimate of net rentable square feet based, in part, on past leases. The net rentable square feet included in such office leases is generally determined consistently with the Building Owners and Managers Association, or BOMA, 2010 measurement guidelines. Net rentable square footage may be adjusted from the prior period to reflect re-measurement of leased space at the properties.

•Percentage leased for each of our retail and office properties and the retail portion of the mixed-use property is calculated as square footage under leases as of December 31, 2023, divided by net rentable square feet, expressed as a percentage. The square footage under lease includes leases which may not have commenced as of December 31, 2023. Percentage leased for our multifamily properties is calculated as total units rented as of December 31, 2023, divided by total units available, expressed as a percentage.

•Annualized base rent is calculated by multiplying base rental payments (defined as cash base rents, before abatements) for the month ended December 31, 2023, by 12. Annualized base rent per leased square foot is calculated by dividing annualized base rent, by square footage under lease as of December 31, 2023. In the case of triple net or modified gross leases, annualized base rent does not include tenant reimbursements for real estate taxes, insurance, common area or other operating expenses. Total abatements for leases in effect as of December 31, 2023 for our retail and office portfolio equaled approximately $7.1 million for the year ended December 31, 2023. Total abatements for leases in effect as of December 31, 2023 for our mixed-use portfolio equaled approximately $0.1 million for the year ended December 31, 2023. Total abatements for leases in effect as of December 31, 2023 for our multifamily portfolio equaled approximately $0.5 million for the year ended December 31, 2023.

•Units represent the total number of units available for sale or rent at December 31, 2023.

•Average occupancy represents the percentage of available units that were sold during the 12-month period ended December 31, 2023, and is calculated by dividing the number of units sold by the product of the total number of units and the total number of days in the period. Average daily rate represents the average rate paid for the units sold and is calculated by dividing the total room revenue (i.e., excluding food and beverage revenues or other hotel operations revenues such as telephone, parking and other guest services) for the 12-month period ended December 31, 2023, by the number of units sold. Revenue per available room, or RevPAR, represents the total unit revenue per total available units for the 12-month period ended December 31, 2023 and is calculated by multiplying average occupancy by the average daily rate. RevPAR does not include food and beverage revenues or other hotel operations revenues such as telephone, parking and other guest services.

•Average monthly base rent per leased unit represents the average monthly base rent per leased units as of December 31, 2023.

Tenant Diversification

At December 31, 2023, our operating portfolio had approximately 796 leases with office and retail tenants, of which 6 expired on December 31, 2023 and 9 had not yet commenced as of such date. Our residential properties had 1,843 leases with residential tenants at December 31, 2023, excluding Santa Fe Park RV Resort. The retail portion of our mixed-use property had approximately 63 leases with retailers. Only one tenant or affiliated group of tenants accounted for more than 9.3% of our annualized base rent as of December 31, 2023 for our office, retail and retail portion of our mixed-use property portfolio. The following table sets forth information regarding the 25 tenants with the greatest annualized base rent for our combined office, retail and retail portion of our mixed-use property portfolios as of December 31, 2023.

(1)Annualized base rent is calculated by multiplying (i) base rental payments (defined as cash base rents before abatements) for the month ended December 31, 2023 for the applicable lease(s) by (ii) 12.

(2)Name withheld at tenant's request.

Geographic Diversification

Our properties are located in Southern California, Northern California, Washington, Oregon, Texas and Hawaii. The following table shows the number of properties, the net rentable square feet and the percentage of total portfolio net rentable square footage in each region as of December 31, 2023. Our six multifamily properties are excluded from the table below and are located in Southern California and Portland, Oregon. The hotel portion of our mixed-use property is also excluded and is located in Hawaii.

(1)Percentage of Net Rentable Square Feet is calculated based on the total net rentable square feet available in our retail portfolio, office portfolio and the retail portion of our mixed-use portfolio.

(2)Includes the retail portion related to the mixed-use property.

Segment Diversification

The following table sets forth information regarding the total property operating income for each of our segments for the year ended December 31, 2023 (dollars in thousands).

Lease Expirations

The following table sets forth a summary schedule of the lease expirations for leases in place as of December 31, 2023, plus available space, for each of the ten calendar years beginning January 1, 2024 at the properties in our retail portfolio, office portfolio and the retail portion of our mixed-use portfolio. The square footage of available space excludes the space from 6 leases that terminated on December 31, 2023. In 2024, we expect a similar level of leasing activity for new and expiring leases compared to prior years with overall positive increases in rental income. However, changes in rental income associated with individual signed leases on comparable spaces may be positive or negative, and we can provide no assurance that the rents on new leases will continue to increase at the above disclosed levels, if at all.

The lease expirations for our multifamily portfolio and the hotel portion of our mixed-use portfolio are excluded from this table because multifamily unit leases generally have lease terms ranging from seven to fifteen months, with a majority having twelve-month lease terms, and because rooms in the hotel are rented on a nightly basis. The information set forth in the table assumes that tenants do not exercise any renewal options.

(1)Annualized base rent is calculated by multiplying base rental payments (defined as cash base rents (before abatements)) for the month ended December 31, 2023 for the leases expiring during the applicable period, by 12.

(2)Annualized base rent per leased square foot is calculated by dividing annualized base rent for leases expiring during the applicable period by square footage under such expiring leases.
