Thank you, Tyler. We are off to a great start this year and are particularly encouraged by the strength we continue to see across our West Coast markets. We reported solid first quarter financial results with both FFO per share and same-store results exceeding our expectations. Across our stabilized portfolio, we've signed new or renewing leases on approximately 300,000 square feet of space that were up 26% on a GAAP basis and 15% on a cash basis. We continue to backfill our four material 2018 expirations ahead of schedule. We re-leased approximately 70% of the expiring space in Bellevue and are making excellent progress in the two San Diego explorations. And as we reported in our last call, we commenced construction on phase 1 of The Academy on Vine, our mixed use development project in the Hollywood sub market and acquired three lab building in South San Francisco's major biotechnology hub of Oyster Point. Now let me provide some more color. Market conditions are showing remarkable strength across the West Coast region. Generally, we are seeing decline in vacancy rates, higher leasing volume, increased rents, limited supply and increased demand across our markets. The fundamentals are almost as strong as we've seen in the cycle so far with big tech and big content creators continuing to grow, and the fire category following. Seattle remains one of the best performing markets in the country, area of fundamentals continues to improve both on the office in life science products, and new supply remains limited. Los Angeles continues to be the recipient of growth from many industries including entertainment and content creation. In San Diego we are seeing the leasing velocity increased over the past six months coming from a broad cross section of industries including, defense, technology, life science in the fire category. The market's strength is evident in our leasing success where we continue to make progress on our 2018 explorations as well as future explorations. As a reminder, late last year we backfilled all of the expiring Delta Dental space at 100 First Street with Okta. In Seattle, we saw a 97,000 square feet of leases so far this year with very tenants at Skyline Tower in Bellevue. The majority of these leases will replace the 11,000 square foot move out we had in February by Valve. Cash rents on the new leases were higher by 59% and GAAP rents were higher by 86% when compared to the prior lease. In San Diego, we're in advanced discussions to backfill more than half of the expiring Bridgepoint space on the I-15 corridor, assuming we are successful in completing these transactions. We'll have effectively completed the releasing of the Seattle and San Francisco 28 explorations and be well ahead of schedule on the San Diego explorations. We've also made some tremendous progress on future explorations including, our only two 2019 expressions that are greater than 100,000 square feet. ISP and affiliate of Provident Health, a life science tenant at 401 Terry in South Lake Union signed an early renewal for 141,000 square feet extending its expiration from 2021 to 2031. In Silicon Valley we signed renewals totaling 169,000 square feet with two life science tenants, both of which were scheduled to expire in 2019. We received notice that Microsoft will move out of our Westlake Terry building in South Lake Union in 2019, thereby triggering Amazons must take for all 125,000 square feet that will now expire in 2030. And at our Stanford Research Park asset in Palo Alto, the existing biotech tenant have signed it's 116,000 square foot lease under the same terms of the Stanford University, significantly improving the credit profile that asset. These transactions on a combined basis will generate rent increases of 14% on a cash basis and 33% on a GAAP basis. Moving to development, we remain on track with our current construction projects. At 100 Hooper as we previously reported, we executed a 314,000 square foot lease with Adobe last year for the entire of our office portion of the 400,000 square foot project. We deliver the Core &. Shell to Adobe earlier in the month, anticipate occupancy in phases late in the year. The remaining 86,000 square feet of projects is PDR space and we just signed two PDR leases totaling 33,000 square feet, bringing the overall project to 87% leased on a square footage basis, and 93% leased on an economic basis. At the exchange, we expect to deliver the Core &. Shell and Dropbox in late May. We also continues that our three other construction projects 333 Dexter in South Lake Union submarket of Seattle, phase 1 of the Academy on Vine, and phase 1 of our One Paseo mixed-use project in Del Mar where we now leased 51% of the retail space and expect to be over 80% committed next quarter. As a matter of interest, the shops at One Paseo was recently voted best new retail in the region, highlighting the much anticipated delivery of our One Paseo project. To summarize these five projects, we currently total just over 2.1 million square feet of office space, 120,000 square feet of retail space, and 237 residential units. Together they represent a total estimated investment of $1.7 billion, with remaining incremental spending of approximately $700 million. More than half of the office space is leased and on schedule to deliver by year end. Overall, we expect to generate over $120 million of NOI from these five projects. As we discussed in last quarter's call in January, we purchased three office in lab building $111 million in the Oyster Point submarket of South San Francisco, and acquisition that takes us into one of the most vibrant life science markets in the U.S. today, is approximately 80% occupied and represents a mid 6% yield upon stabilization. As most of you know we are pursuing a development opportunity directly adjacent to our new Oyster Point acquisition. We have a confidentiality agreement that prohibits us from discussing details at this time, but we are very excited about this opportunity given the strength of the life science sector, as well as this particular location. We expect to be able to provide details on this lab acquisition and our development plans at our June 4th Investor Day in New York City. We are also making progress on our capital recycling goals for 2018. We are in the process of taking to market a combination of non-core and core assets, and expect to meet our previously stated objective of $250 million to $750 million of dispositions with closings in the second half of this year. To summarize four months in the 2018, we are seeing rising demand, shrinking supply, and upward pressure on rental race for top quality properties across our West Coast markets. We have the youngest and most sustainable portfolio of year towards the modern worker and continue to see opportunities in strong returns and create shareholder value, largely in development, and we remain committed to pursuing these opportunities with prudence and financial discipline. That completes my remarks. And I am going to turn the call over to Jeff for a closer look at our markets. Jeff.
