Thank you, Isaac. PMT reported strong earnings in the first quarter of 2023, as solid results from its credit-sensitive strategies and income excluding the impacts of market-driven fair value changes, were partially offset by fair value declines in its interest rate-sensitive strategies, which drove a tax benefit. Net income to common shareholders was $50 million or $0.50 per common share, representing an annualized return on equity of 14%. Net of the $0.40 dividend, book value per share was up to $15.96. PMT spent $8 million on share repurchases in the first quarter, and it remains an attractive use of capital when PMT's share price is well below book value per share. Dan Perotti, Senior Managing Director and Chief Financial Officer, will review additional details of PMT's financial performance later on in this discussion. With mortgage interest rates currently still above 6%, the most recent third-party forecast for 2023 originations range from $1.6 billion to $1.8 trillion, down meaningfully from 2022. While many industry participants have taken the appropriate steps to reduce capacity, the pace of that reduction has been slow, and we believe overcapacity still remains. That being said, average quarterly origination forecast for the remainder of 2023 are meaningfully higher than the industry's estimated origination volumes in the first quarter, consistent with our own expectations as we move into the more typical home buying season. Originations in 2024 are currently expected to approach more normalized levels with estimates suggesting an origination market above $2 trillion. It is our expectation that mortgage REITs with diversified investment portfolios, efficient cost structures and strong risk management practices such as PMT, are best positions to manage through the volatility presented by the current market environment. Throughout April, market credit spreads have continued to tighten, and we continue to see improvements in the structured product markets. This has driven additional capital deployment and opportunistic investments. Year-to-date, PMT has invested $64 million in these investments, including $52 million after the quarter end. The underlying fundamentals of our lender risk share investments remain strong, consisting of seasoned loans with low current LTVs having benefited from the strong home price appreciation we've seen in recent years. With delinquency rates at pre-COVID levels and current strong employment data, recent realized losses on our CRT investments have remained limited. The return potential for PMT's credit-sensitive strategies remain strong and improved slightly from the prior quarter as we recently issued new CRT term notes to finance the balance of CRT investments previously financed with securities repurchase agreements. Dan will expand further on this during his section of the discussion. Signs of increasing inflation are slowing, and we believe the Federal Reserve is getting closer to the end of its tightening cycle, which we expect will benefit PMT's interest rate-sensitive strategies, assuming volatility declines. Additionally, higher short-term rates have increased earnings from custodial balances and deposits in recent quarters. Deposit balances are trending higher from the seasonal loans in the first quarter, driving our expectations for continued strong performance for the remainder of 2023. Over the long term, we believe the underlying performance of PMT's MSR portfolio will be strong, supported by PFSI's industry-leading servicing capabilities, workflows and proprietary technology. The return potential for our MSRs is essentially unchanged from our expectations last quarter, reflecting low and relatively stable expected prepayment speeds. Turning to correspondent production. PennyMac has many strong relationships with purchase-focused build-their-own mortgage companies which, combined with the exit of other channel participants, has driven the consistency of our acquisition volumes in recent quarters despite a much smaller origination market. Investments made by our manager, PFSI, have resulted in an extremely low cost structure, allowing us to operate efficiently. While we estimate that we represented approximately 17% of the correspondent channel over the past 12 months, we believe our market share has been meaningfully higher in more recent periods as sellers seek higher-quality partners like PennyMac. While our position in the correspondent market remains strong, we expect to continue to actively manage PMT's capital deployment among its credit and interest rate-sensitive strategies. We will continue to leverage our synergistic relationship with PFSI. And beginning in the second quarter, PMT is expected to sell PFSI an increased proportion of its newly originated conventional correspondent production. At the same time, we are evaluating new credit investments and other market opportunities such as bulk MSRs with low coupons, stable cash flows and low expected prepayment activity that complement PMT's current investment portfolio. PFSI's interest in building its own servicing portfolio with current coupon mortgages enables us to maintain PMT's strong and consistent bid in the correspondent channel, while actively managing its capital allocation. As such, our projected equity allocation for correspondent activities over the coming quarters has decreased, while our projection for the return on equity of the correspondent activity that we will continue to engage in has increased. On Slide 7 of our first quarter earnings presentation, we illustrate the run rate potential from PMT's investment strategies, which represents the average annualized return and quarterly earnings potential that PMT expects over the next 4 quarters. As you can see, we expect the quarterly run rate return for PMT's strategies to average $0.40 per share or an 11% annualized return on common equity, reflecting performance expectations in the current mortgage market. Now I'd like to turn the call over to Dan Perotti, Senior Managing Director and Chief Financial Officer, who will review the drivers of PMT's first quarter financial results.
