In this context, managers may apply an internal scoring methodology to grade assets as part of their investment decisions. These scoring methods in many cases rely on a weighted approach based on certain factors, many of which may be subjective. In addition, managers may rely significantly on a single guiding metric, such as yield, but still need to further control for other factors, such as credit risk, to be comparable.<\/p>\n\n\n\n<p>Investment decisions are further complicated by various constraints. Constraints may be market driven, such as the availability of investments or market prices. Investor-mandated factors such as average credit quality, percentage limitations and duration may also come into play, as do regulatory factors, such as SEC, NAIC, Federal Reserve, Basel III rules.<\/p>\n\n\n\n<p>These constraints can apply across all areas in fixed income, whether the asset is an investment grade credit, a high-yield bond, a broadly syndicated loan, private debt or structured credit. Constraints could also extend to other \u2018cash flow intensive\u2019 investments, such as commercial real estate and infrastructure.<\/p>\n\n\n\n<p>Given the myriad factors that investors must consider, it comes as no surprise that portfolio optimization in fixed income is a sophisticated process with complex methods and techniques.<\/p>\n\n\n\n<p>In this paper we present a framework designed to address these complex portfolio allocation challenges. This framework offers a single universal metric, the Alter Domus Score (\u2018ADS\u2019), which can arm managers with a solution for efficiently measuring an optimal portfolio allocation that is objective and comparable across any fixed income investment.<\/p>\n\n\n\n<p>The ADS, which is an asset-based measure, is also robust and controls for information relevant to any fixed income investment &#8211; including those tied to <a href=\"https:\/\/alterdomus.com\/services\/private-debt-solutions\/asset-based-loan-abl-servicing\/\">asset based loans<\/a> &#8211; ranging from cashflow characteristics and credit worthiness to market price, pre-payment, and illiquidity costs.<\/p>\n\n\n\n<p>We will detail the elements of the ADS, including the underlying framework, and illustrate the relationship between the ADS and changes to certain key asset-based characteristics.<\/p>\n\n\n\n<p class=\"has-large-font-size\"><strong>Why Trade Optimization? <\/strong><\/p>\n\n\n\n<p>Trade optimization addresses a fundamental economic problem: maximizing the efficient and productive use of limited resources, specifically <em>investable capital<\/em>. Fixed income managers must, therefore, choose from among various investment opportunities to maximize the overall portfolio return given each investment\u2019s attributes, which include cashflows, credit risk, and market price.<\/p>\n\n\n\n<p>In most cases, managers are also faced with a variety of constraints, such as credit quality, maturity, and diversification limits, to name but a few, which adds more complexity to their decision-making process.<\/p>\n\n\n\n<p>Essentially, managers aim to navigate these variables to deliver the best value for their investments. &nbsp;&nbsp;&nbsp;<\/p>\n\n\n\n<p>The ADS presents a framework that relies on a single metric and objectively accounts for economic factors that are key to any fixed income investment. This framework is particularly valuable for managers bound by constraints, helping them to make the best investment allocations when weighing tradeoffs. The ADS serves as a complement and support to existing methods used by investment managers. &nbsp;<\/p>\n\n\n\n<p class=\"has-large-font-size\"><strong>The ADS: an objective and universal measure for trade optimization<\/strong><\/p>\n\n\n\n<p>The ADS is an objective measure that is rooted in fixed income theory.<\/p>\n\n\n\n<p>Essentially, it represents the discounted and risk-adjusted cashflows for any expected stream of cash flows, including fixed income instruments, such as bonds, loans, and asset-backed securities (ABS).<\/p>\n\n\n\n<p>The ADS is easily comparable across all securities since it is a measure based on a single dollar (or any currency) value at risk. This feature allows any prospective universe of fixed income investments to be rank ordered on a pro-forma basis to determine an optimal portfolio allocation that is subject to constraints.<\/p>\n\n\n\n<p>The score means that a fixed income investor can compare a bond to a loan or an ABS security \u2013 or even a real estate investment \u2013 when selecting the optimal portfolio allocation investment decision.<\/p>\n\n\n\n<p>The score is agnostic as to the type of underlying investment and relies on the individual cashflow characteristics of the asset, factoring in the time value of the expected cash flow and uncertainties due primarily to the credit risk of the borrower and potential prepayments.<\/p>\n\n\n\n<p class=\"has-large-font-size\"><strong>Digging into the detail: the formula behind the ADS<\/strong><\/p>\n\n\n\n<p>The ADS is calculated based on the following formula (see Appendix for detailed description of inputs).<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"120\" src=\"https:\/\/alterdomus.com\/wp-content\/uploads\/2025\/01\/AD-Score-Forumla-1-1024x120.png\" alt=\"\" class=\"wp-image-5112\" srcset=\"https:\/\/alterdomus.com\/wp-content\/uploads\/2025\/01\/AD-Score-Forumla-1-1024x120.png 1024w, https:\/\/alterdomus.com\/wp-content\/uploads\/2025\/01\/AD-Score-Forumla-1-300x35.png 300w, https:\/\/alterdomus.com\/wp-content\/uploads\/2025\/01\/AD-Score-Forumla-1-768x90.png 768w, https:\/\/alterdomus.com\/wp-content\/uploads\/2025\/01\/AD-Score-Forumla-1.png 1238w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>To make effective comparisons across assets, the outstanding principal balance of the asset is first normalized to an indexed value of 1, which results in the market value (MV) to be a percentage of the indexed value.

The asset is therefore \u2018undervalued\u2019, as indicated by the asset\u2019s risk\/return profile.<\/p>\n\n\n\n<p>These are assets that offer the manager favorable investment characteristics, as the value of the risk-adjusted cash flows is greater than the price to acquire those cash flows.<\/p>\n\n\n\n<p><strong>Example 2:<\/strong> In cases where the ADS is less than 1, the time-value adjusted and risk-adjusted cashflows based on the manager\u2019s expectations is <em>less<\/em> than what the market price is reflecting. The asset is thus \u2018overvalued\u2019, as indicated by the asset\u2019s risk\/return profile.<\/p>\n\n\n\n<p>The manager will seek to sell these assets since the proceeds from those sales would exceed the manager\u2019s fundamental assessment of what those cash flows are worth.<\/p>\n\n\n\n<p><strong>Example 3:<\/strong> In cases where the ADS score is equal to 1, the time-value adjusted and risk-adjusted cashflows based on the manager\u2019s expectations is <em>equal<\/em> to what the market price is reflecting. So, the asset is \u2018fairly valued\u2019, as indicated by the asset\u2019s risk\/return profile. These assets have market values consistent with the manager\u2019s fundamental assessment, and the manager would therefore be indifferent to holding, buying, or selling these assets.<\/p>\n\n\n\n<p>When working through these scenarios, it becomes clear that a manager can begin to utilize the ADS as a metric for comparing and effectively rank-ordering decisions across different types of fixed income assets.<\/p>\n\n\n\n<p>The ADS can also be used as a tool to inform the manager as to what the risk-based inputs the market is implying. With these inputs on hand, the manager can better assess whether an asset\u2019s market price is rich or cheap.<\/p>\n\n\n\n<p>Manager judgement, of course, is an important element to calculating the ADS.<\/p>\n\n\n\n<p>The ADS could be pre-populated with apparently objective inputs and additional manager overlay could significantly improve the quality of the ADS and its utility as a tool to support portfolio optimization.<\/p>\n\n\n\n<p>Assessment of prepayment rates and credit risk inputs are informed by asset manager expertise and play a big role in calculating the ADS.<\/p>\n\n\n\n<p class=\"has-large-font-size\"><strong>Dissecting the AD-Score<\/strong><\/p>\n\n\n\n<p>The tables below illustrate the relationship between the ADS and changes to certain key inputs holding all else equal. We have intentionally kept the analysis simple so that we could better illustrate the mechanics behind the score.<\/p>\n\n\n\n<p>A more thorough analysis, inclusive of actual cash flow payment dates (we assume annual for our simple analysis), spot risk-free rates (we assume a flat risk-free curve), more dynamic prepayment rates, and other more precise inputs are considered as part of the ADS.<\/p>\n\n\n\n<p>For simplicity we also assume the assets are floating rate senior secured loans, but set at a fixed rate, and have a narrow band of possible recovery rates. The probabilities of default (PDs) are based on the Moody\u2019s idealized default rate table.<\/p>\n\n\n\n<p><strong>The Tables that follow illustrate how the ADS score may shift under different scenarios:<\/strong><\/p>\n\n\n\n<p class=\"has-medium-font-size\"><strong>Table 1: Impact of Coupon Rates and Credit Risk Ratings to the ADS<\/strong><\/p>\n\n\n\n<p>The first part of the analysis (see Table 1) shows the calculated ADS for a group of six stylized loans. The loan coupons range between 5.50%-10.75% (4.50% risk-free rate and risk premiums between 1.00%-6.25%) and have current ratings in the Ba2-Caa1 range. The loans have six-year stated maturities (with 10% constant prepayment rate \u2013 CAP) and assumed recovery rates of 45%. Note that for further simplicity we assume the current market values are 100% (or equal to par), and that the stated coupons are such that the current ADS is 1.00 (or \u2018fairly valued\u2019 at par).<\/p>\n\n\n\n<p>Table 1 also shows a range of possible ADS scores based on changes to credit risk ratings and coupons. It can also be viewed as changes in the manager\u2019s opinion of credit risk (or PD) associated with the loan. Furthermore, the ADS values can reflect the manager\u2019s opinion on its own fundamental assessment of the loan cashflows (or C-RAV), holding all else constant.<\/p>\n\n\n\n<p>In other words, these ADS values can reflect the manager\u2019s opinion on what the fair value (or price) should be as a percent of par and can be used to compare to what the market price is offering.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"589\" src=\"https:\/\/alterdomus.com\/wp-content\/uploads\/2025\/02\/ADS-Loan-rating-or-PD-vs.-loan-coupon-1024x589.png\" alt=\"\" class=\"wp-image-5137\" style=\"width:896px;height:auto\" srcset=\"https:\/\/alterdomus.com\/wp-content\/uploads\/2025\/02\/ADS-Loan-rating-or-PD-vs.-loan-coupon-1024x589.png 1024w, https:\/\/alterdomus.com\/wp-content\/uploads\/2025\/02\/ADS-Loan-rating-or-PD-vs.-loan-coupon-300x172.png 300w, https:\/\/alterdomus.com\/wp-content\/uploads\/2025\/02\/ADS-Loan-rating-or-PD-vs.-loan-coupon-768x442.png 768w, https:\/\/alterdomus.com\/wp-content\/uploads\/2025\/02\/ADS-Loan-rating-or-PD-vs.-loan-coupon-1536x883.png 1536w, https:\/\/alterdomus.com\/wp-content\/uploads\/2025\/02\/ADS-Loan-rating-or-PD-vs.-loan-coupon.png 1595w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Table 1: Impact of Coupon Rates and Credit Risk Ratings to the ADS<\/figcaption><\/figure>\n\n\n\n<p>Initial noteworthy observations show that investors require compensation via higher coupons that are commensurate with lower rated loans, holding all else equal, such as a larger risk premium for riskier loans.<\/p>\n\n\n\n<p>This can be reflected in the highlighted cells across the loans where the market price clears at par (also reflected with an ADS of 1.00).

The ADS is also simple, robust and controls for critical information, whether it is objective or subjective, relevant to any fixed income investment.<\/p>\n\n\n\n<p>For AD clients, including clients of Solvas and Enterprise Credit &amp; Risk Analytics, the ADS is offered as an additional measure to support our clients with their trade optimization, portfolio allocation, and risk analytics.<\/p>\n\n\n\n<p>Please contact <a href=\"mailto:Eric.Tannenbaum@alterdomus.com\">Eric.Tannenbaum@alterdomus.com<\/a> for further information on how to access the ADS.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>Appendix: Calculation of the Alter Domus Score<\/strong><\/p>\n\n\n\n<p>The first step to compute the Alter Domus Score (ADS) for any fixed income instrument is to normalize the initial face amount to a value of 1 in the relevant currency.
