Subsequent Events	11. Subsequent Events Acquisitions On July 23, 2019, we entered into definitive agreements with Secure Income REIT (“SIR”) to acquire freehold interests in eight private hospitals located throughout England for an aggregate purchase price of approximately £347 million. The hospitals will be leased to Ramsay Health Care (“Ramsay”) pursuant to in-place net leases with an approximate 18-year remaining lease term and include annual fixed and periodic market-based escalations. On July 10, 2019, we entered into definitive agreements pursuant to which we will invest in a portfolio of 14 acute care hospitals and two behavioral health facilities currently owned and operated by Prospect Medical Holdings, Inc. (“Prospect”) for a combined purchase price of approximately $1.55 billion. Our investment will consist of (i) the acquisition of the real estate of 11 acute care hospitals and two behavioral health facilities for $1.4 billion and the subsequent leasing of such facilities back to Prospect in the form of two master leases; (ii) a $51.3 million mortgage loan, secured by a first mortgage on an acute care hospital; and (iii) a $112.9 million term loan which we expect will be converted into the acquisition of two additional acute care hospitals upon the satisfaction of certain conditions. The master leases, mortgage loan and term loan will be cross-defaulted and cross-collateralized. The master leases and mortgage loan have substantially similar terms, with a 15-year fixed term subject to three extension options, plus annual increases based on inflation. Although no assurances can be made that these investments will occur, we believe the Prospect and SIR investments will close during the 2019 third quarter. Financing On July 18, 2019, we completed an underwritten public offering of 51.75 million shares (including the exercise of the underwriters’ 30-day option to purchase an additional 6.75 million shares) of our common stock, resulting in net proceeds of $858.1 million, after deducting underwriting discounts and commissions and estimated offering expenses. On July 26, 2019, we completed a $900 million senior unsecured notes offering (“4.625% Senior Unsecured Notes due 2029”). Interest on the notes is payable semi-annually on February 1 and August 1 of each year, commencing on February 1, 2020. The notes were issued at 99.5% of par value, pay interest at a rate of 4.625% per year and mature on August 1, 2029. We may redeem some or all of the notes at any time prior to August 1, 2024 at a “make whole” redemption price. On or after August 1, 2024, we may redeem some or all of the notes at a premium that will decrease over time. In addition, at any time prior to August 1, 2022, we may redeem up to 40% of the notes at a redemption price equal to 104.625% of the aggregate principal amount thereof, plus accrued and unpaid interest thereon, using proceeds from one or more equity offerings. In the event of a change in control, each holder of the notes may require us to repurchase some or all of the notes at a repurchase price equal to 101% of the aggregate principal amount of the notes plus accrued and unpaid interest to the date of purchase. We intend to use the net proceeds from the 4.625% Senior Unsecured Notes due 2029 offering along with the proceeds from our July 2019 equity offering to help finance the commitments described above. Furthermore, the completion of the offerings described above resulted in the cancellation of a $1.55 billion senior unsecured bridge loan facility commitment from Barclays Bank PLC that we received on July 10, 2019, to fund our investment in the Prospect portfolio. With this commitment, we paid $3.9 million of underwriting and other fees, which we fully expensed upon the cancellation of the commitment.
