Thank you, Tyler. Hello everyone and thank you for joining us today. I will start my comment today with a brief review of the West Coast market conditions. Then I will cover 2015 highlights, and I will finish with some color and outlook for 2016. While we recognize that there are macro factors creating uncertainties about the capital markets and future business conditions, West Coast market fundamentals for office space continue to outperform. We see strong demand and limited supply for the type of work environments that our tenant base requires. Rental rates and net absorption continue to increase, while vacancy rates continue to decrease year-over-year in the innovation driven markets of San Francisco, Seattle, Los Angeles, and the submarkets of Del Mar in San Diego. Cap rates and IRRs on West Coast transactions continue to reflect strong demand for quality real estate. While Bay Area VC funding in the fourth quarter was down from the highs of 2014 and early 2015, it is still well above the healthy levels of 2011, 2012, and 2013, which was a period of considerably higher vacancy rates. And already early in the first quarter, brokers are advising that there are currently 750,000 square feet of new leases in process in the San Francisco market. Against this backdrop, KRC had another strong year of operating performance in 2015. We exceeded every one of our internal targets. On leasing performance, we signed 1.5 million square feet during the year, exceeding our goal of 1 million square feet, with strong cash rent spreads of 22%. On year end occupancy, we provided initial guidance of 94% and ended the year 94.8%. On same store cash NOI growth, we provided initial guidance range of 2.5% to 3.5% and achieved 4.7% for the year. And on FFO and FAD per share, we initially provided FFO per share guidance of $3.27, and increased to $0.12 throughout the year. And we beat our FAD per share budget by more than 25% for the payout ratio of 66% at year end. We managed our development program, with great focus and discipline, delivering fully leased, under construction projects on time and on budget, securing critical entitlement approvals for future projects and reloading our pipeline on a selective basis, with projects that offer clear value creation opportunities. Excuse me, I am getting a cold. We maintained a strong balance sheet and availability to capital, exceeding our capital recycling targets, raising $790 million in new public debt and equity, decreasing debt-to-EBITDA from 7.4 times last year to 5.7 times this year, and earning credit grade upgrades from both major rating agencies. More specifically on the operations front, we finished the year with fourth quarter leasing activity of approximately 398,000 square feet of new or renewing leases, at rents that were 15% higher on a cash basis, and 25% higher on a GAAP basis. This strong leasing performance resulted in better than expected cash same store growth of 9% in the fourth quarter. We also have 350,000 square feet of LOIs currently in place. This continued strength in all of our markets, not only translate into strong operating results, but also increase interest in all of our development projects. Last quarter we delivered and stabilized our two building 339,000 square foot office project at Crossing 900 in Redwood City, that is fully leased to [box]. Combined with the delivery of the 100,000 square foot [new office] space at Columbia Square last summer, these two projects represented total estimated investment of $270 million with an average stabilized cash ROC of more than 8%. Based on today's cap rates, value creation of both projects is estimated to total approximately $275 million, effectively doubling the investment. That leaves us with six projects under construction or in lease-up. Two of the six, Salesforce and Dropbox will be delivered fully leased in the second quarter. The new office component of Columbia Square will be complete from a base building perspective this quarter, it is 58% leased with good activity from both large entertainment users and from smaller prospects with whom we are currently negotiating LOIs. The residential component of Columbia Square will begin its projected one year leaseup phase in the second quarter. The Heights in Del Mar is now in lease negotiations, in process for two of the three floors, and as you know, last summer, we started the exchange on 16th in Mission Bay, with a total projected investment of $485 million. The project is expected to be completed in the third quarter of 2017. We remain in advanced negotiations with several prospective tenants, and we are seeing interests from new prospects on a regular basis. On the entitlement front, we made significant progress on both, One Paseo and the Flower Mart during the year. We effectively settled all remaining outstanding issues with the community groups and surrounding neighbors on the One Paseo mixed use project in Del Mar and San Francisco with the Flower Mart side, we successfully found common ground and reached agreements with local community groups. And we are making great progress on entitlement and design for both projects. Finally, we acquired two additional development opportunities in 2015 for an aggregate purchase price of $128 million. 333 Dexter in the popular South Lake Union neighborhood of Seattle and 100 Hooper, a fully entitled site in San Francisco. To fund our growth and take advantage of the strong market for real estate, we continue to have success through our capital recycling program. In mid-January, we closed the sale to Intuit, the entire office campus at lease from us in San Diego, for a purchase price of $262 million. The campus has four buildings encompassing roughly 466,000 square feet. We also sold a non-strategic 7.6 acre parcel of land in Carlsbad for $4.5 million last month and we are in discussion to sell the remaining adjacent three parcels. Combined with the transactions we completed in 2015, which consisted of 10 buildings and a land parcel, we have generated $602 million of proceeds since January 2015 to help fund our development projects. Tyler will provide more detailed disposition guidance later in the call, but we continue to be very aggressive on this front. Now let's move to the year ahead; based on our discussions with global heads of real estate, executives of companies in our markets and the brokerage community, demand continues to look strong against the backdrop of low vacancy rates, low availability of contiguous blocks of desirable space, constrained supply and increasing rental rates. We are encouraged that numerous companies are in the planning stages for significant new requirements over the next two to four years in all of our markets. On the transaction front, cap rates remain very favorable, with a deep and diverse pool of buyers. Of course, we don't have a crystal ball, so we can only report on what we are seeing and hearing. We will continue to take our lead from the conditions we see on the ground, making decisions, as we move through the year with the same discipline that we have always exercised. Our overwriting goal remains the same, to preserve and build long term value for our shareholders, that is why we remain committed to markets with strong, long term growth dynamics and those that attract an innovative workforce in the growing companies that need their talents. That is why we are adamant about location in these markets seeking out neighborhoods with the same cultural personalities, attractive lifestyle amenities and excellent access to public transportation and the other required services. And that's why we are prudent in our decisions about when to pursue each new development project. As most of you know, we have a strong track record of pre-leasing. Approximately 80% of our development has been leased upon construction/completion, and 90% upon stabilization and all of our projects were built at very accretive returns. As stated in prior conference calls, we have four potential near term development projects, any of which could start this year, subject to macro and market conditions. 100 Hooper Street, located in the SOMA District of San Francisco, is fully entitled and we can start construction at any time. Our strategy here remains the same. We will wait for significant leasing momentum at the Exchange or Hooper itself before we break ground. One Paseo, our mixed use development project in Del Mar, is expected to have final entitlement approval by the summer, and at both the Academy in Hollywood and 333 Dexter in Seattle, we expect final governmental approvals by the third quarter. Further out on the development horizon is the Flower Mart project in San Francisco. Our expected timeframe to move forward is about two years, again, subject to market conditions and receipt of entitlements. To wrap up, we believe we are entering the year with a premier West Coast office portfolio, a development pipeline that will create substantial value over time, and as always, a strong balance sheet. Our key objectives for 2016 are to continue to execute a strong leasing program, both in our stabilized portfolio as well as our development pipeline, capturing better rent growth, delivering new properties on time and on budget, succeed with our capital recycling program and maintain our financial strength. With that, I will turn the call over to Jeff for a closer look at our markets. Jeff?
