Thank you, Olivia. Good morning. Welcome to the first earnings name for Office Properties Income Trust, which is the fruits of the merger among Government Properties Income Trust and Select Income REIT. On the ultra-modern call, I will provide a top-level view of OPI and a replacement on our capital recycling program earlier than turning the decision over to Jeff Leer to offer a high-level view of financial results.
Before I start, I would love to spotlight that due to the merger last on the final enterprise day of the sector, fourth-quarter effects reflect a mixed stability sheet and best GOV’s running results. We provided seasoned forma consolidated consequences as if the merger had closed on October 1 rather than December 31 in our earnings release and supplemental disclosure package deal to assist in rectifying this.
Our working strategy for OPI will vary from our operating procedure for GOV and SIR as stand-on my corporations. One fabric distinction will be our plan to actively recycle capital through asset sales at OPI, first to control leverage, however ongoing to shape the portfolio. In doing so, we anticipate lessening the average age of our residences, growing our weighted common closing lease term, and decreasing destiny capital necessities.
Another strategy shift may be to awareness of favoring the purchase of first-era buildings. We believe this may increase the probability of tenants renewing rentals, which ought to impact OPI’s occupancy and reduce ongoing leasing capital effectively. These two strategies are expected to create lengthy-time period coins that go with the flow accretion and contribute to maintaining a nicely included dividend.
Entering 2019, OPI has a broader investment strategy to foster increase and is an organization with accelerated scale and greater diversification. We trust we’ve got decreased danger at OPI by reducing our attention to US authorities tenants, increasing geographic diversification, lengthening our weighted average remaining rent term, developing a more nicely-laddered hire expiration agenda, and decreasing our publicity to floating charge debt. We have also accelerated our board’s size, including two impartial trustees, which increases the range of girl trustees to 38% and the entire quantity of unbiased trustees to seventy-five %.
On December 31, 2018, OPI’s portfolio consisted of 247 buildings containing 31. Nine million square feet that were 91% fascinated about a weighted common ultimate rent term of five.7 years and an average constructing age of approximately 17 years. 64.9% of our annualized lease is paid via investment-grade rated tenants, which we believe is one of the maximum probabilities of rent paid by investment-grade rated tenants within the office REIT region.
The US government is our biggest tenant, accounting for 25.6% of the annualized lease. This reduces 45.6% premerger and no different tenant bills for extra than 2.7% of the annualized contract. We have additionally decreased the share of rentals expiring via the quit of 2021 from 47.4% of annualized hire premerger to 27% at the cease of the region.
OPI’s investment strategy will attract attention to workplace houses and markets with robust financial fundamentals to support growth and consist of residences leased to the unmarried tenant and multi-tenant houses leased to high credit score first-class tenants like government entities.
Critical standards for acquiring single-tenant houses will encompass evaluating how strategic an asset is to the tenant’s commercial enterprise, specializing in company headquarters, build-to-healthy homes, and buildings where the tenants have invested significant capital. Single-tenant building acquisitions can even encompass a minimum ultimate hire period of 7 years. Properties leased to authorities tenants will include each single-tenant and multi-tenant homes and will cognizance of companies with high protection needs or an assignment that is strategic to the building’s place. We count on to collect usually first-era buildings where there’s a relatively excessive possibility of renewing the tenant in location and wherein ongoing capital needs are expected to be highly modest in comparison to older homes.
We are turning to our capital recycling. In addition, to begin with, promoting houses to lessen leverage, we plan to have an ongoing capital recycling program of $one hundred million to $300 million annually to form our key portfolio metrics and control current capital necessities. As a reminder, we recently introduced the completion of the sale of 34 buildings in the metro DC market for gross proceeds of $198.5 million. This completed the disposition plan related to our First Potomac Realty Trust acquisition in the fourth sector of 2017. In combination, we offered $520 million of homes to finance the purchase permanently.
Today, OPI has 36 buildings in a disposition plan to finance our merger with SIR permanently. Two of those houses are below agreement to promote for about $ seventy-seven million in gross proceeds, and the stability of the buildings are in various ranges of advertising. We are promoting approximately 5.9 million square feet of homes in the mixture that we consider will generate extra than $750 million in gross proceeds. Considering our development on this disposition plan because it is completing the merger, we remain confident that OPI will significantly achieve the sale of these houses earlier than announcing second zone earnings. This will role the organization to reenter the acquisition market in the second half of-of 2019 at the same time as persevering with to form the portfolio with a capital recycling application.
In summary, we are excited about the opportunities available to OPI as a more strong company with a grander scale and economic flexibility. We additionally look forward to executing on our capital recycling plan and returning to growth within the 2d 1/2 of 2019. I will now flip the call over to Jeff to provide a top-level view of financial results.
