with Pacific Oak Strategic Opportunity REIT II and KBS Legacy Partners Apartment REIT elected to cease participation in the program and obtain separate insurance coverage. We, together with Pacific Oak Strategic Opportunity REIT II, entered into an errors and omissions and directors and officers liability insurance program where the lower tiers of such insurance coverage are shared. The cost of these lower tiers is allocated by our advisor and its insurance broker among each REIT covered by the program, and is billed directly to each REIT. The program is effective through June 30, 2021.
Singapore Transactions
On October 24, 2017, we (through certain subsidiaries) entered into a Portfolio Purchase and Sale Agreement and Escrow Instructions (the “Purchase Agreement”) pursuant to which we agreed to sell, subject to certain closing conditions, the Singapore Portfolio to various subsidiaries of Keppel Pacific Oak US REIT, previously known as Keppel-KBS US REIT, a newly formed Singapore real estate investment trust (the “SREIT”) that intended to list (and subsequent did list, as described below) on the Singapore Stock Exchange (the “Singapore Transaction”). The agreed purchase price of the Singapore Portfolio was $804 million. The Singapore Portfolio consisted of the following properties: 1800 West Loop, Westech 360 (part of the Austin Suburban Portfolio), Great Hills Plaza (part of the Austin Suburban Portfolio), Westmoor Center, Iron Point Business Park, the Plaza Buildings, Bellevue Technology Center, Northridge Center I and II, West Loop I and II, Powers Ferry Landing East, and Maitland Promenade II.
The SREIT is externally managed by a joint venture (the “Manager”) between (i) an entity in which Keith D. Hall, our Chief Executive Officer and a director, and Peter McMillan III, our President and Chairman of the Board of Directors, have an indirect ownership interest and (ii) Keppel Capital Holding Pte. Ltd., which is not affiliated with us or our management. As described in more detail below, the SREIT is expected to pay certain purchase and sale commissions and asset management fees to the Manager in exchange for the provision of certain management services.
On November 2, 2017, Pacific Oak SOR Properties, LLC (“Pacific Oak SORP”), an indirect wholly owned subsidiary of ours, entered into an underwriting agreement (the “Underwriting Agreement”) with respect to the initial public offering of units of the SREIT. The Underwriting Agreement was entered into with the Manager, KBS Pacific Advisors Pte. Ltd., Keppel Capital Holdings Pte. Ltd., GKP Holding LLC, Keppel Capital Investment Holdings Pte. Ltd., DBS Bank Ltd., Merrill Lynch (Singapore) Pte. Ltd., Citigroup Global Markets Singapore Pte. Ltd., and Credit Suisse (Singapore) Limited. KBS Pacific Advisors Pte. Ltd. and GKP Holding LLC are affiliated with the Manager and entities in which Keith D. Hall, our Chief Executive Officer and a director, and Peter McMillan III, our President and Chairman of the board of directors, have ownership and economic interests.
Pursuant to the Underwriting Agreement, the underwriters agreed to procure subscriptions, or subscribe themselves, for an aggregate of 262,772,400 units in the SREIT, at a price of $0.88 per unit (the “IPO Price”), in connection with the Singapore Transaction. Other parties agreed to subscribe for units separately, including Pacific Oak SORP, which, on October 25, 2017, entered into a subscription agreement with the Manager in which it agreed to purchase 59,713,600 units at the IPO Price (the “Pacific Oak SORP Owned Units”) in connection with the initial public offering. Pursuant to the Underwriting Agreement, Pacific Oak SORP granted the underwriters an over-allotment option (the “Over-Allotment Option”) in which it agreed to sell the underwriters up to 15,714,100 of the Pacific Oak SORP Owned Units at the IPO Price, for up to 30 days after the listing. Separately, Pacific Oak SORP agreed to lend the underwriters certain of its Pacific Oak SORP Owned Units for stabilizing transactions following the listing of the SREIT pursuant to a unit lending agreement entered into on November 2, 2017 with the Manager and Merrill Lynch (Singapore) Pte. Ltd. Pursuant to lock-up letters from us and certain of our subsidiaries delivered to the underwriters on November 2, 2017, we and our subsidiaries agreed not to sell, pledge or transfer any of our Pacific Oak SORP Owned Units (other than pursuant to the Over-Allotment Option or lending for stabilizing transactions pursuant to the unit lending agreement described above) for six months following the initial public offering, and not to sell, pledge or transfer 50% of the Pacific Oak SORP Owned Units for 12 months following the initial public offering.
On November 8, 2017, we completed the sale of the Singapore Portfolio to the SREIT. The closing date of the initial public offering and the listing of the SREIT both occurred on November 8, 2017.
