Business & Finance Glossary: S
40 terms starting with S, from a glossary of 559 definitions covering intangible assets, valuations, and key financial concepts.
S-Curve Analysis
A forecasting and valuation technique based on the logistic growth function, which models the adoption or diffusion of technology, products, or innovations as a characteristic S-shaped curve with slow initial growth, rapid acceleration, and eventual saturation. S-curve analysis is used in intangible asset valuation to project revenue trajectories for technology assets, assess the remaining useful life of patents, and evaluate where a product sits in its lifecycle.
Read more →SaaS (Software as a Service)
A software distribution model in which applications are hosted by a service provider and made available to customers over the internet on a subscription basis. SaaS businesses are characterised by recurring revenue, high gross margins, and significant intangible asset value in software and customer relationships.
Read more →SaaS Metrics
The set of key performance indicators specifically designed to measure the health, growth, and unit economics of Software-as-a-Service businesses. Core SaaS metrics include annual recurring revenue (ARR), monthly recurring revenue (MRR), customer acquisition cost (CAC), lifetime value (LTV), churn rate, net revenue retention (NRR), and the Rule of 40. These metrics are essential for SaaS company valuations.
Read more →SAFE (Simple Agreement for Future Equity)
A financing instrument developed by Y Combinator that provides investors with the right to receive equity at a future priced round, subject to a valuation cap and/or discount. SAFEs are simpler than convertible notes, carry no interest, and have no maturity date.
Read more →Sanctions Compliance
The policies, procedures, and controls organisations implement to ensure they do not engage in prohibited transactions with sanctioned countries, entities, or individuals. Sanctions regimes are administered by bodies including OFAC (US), OFSI (UK), and the EU Council, and violations can result in severe criminal penalties, asset freezes, and reputational damage.
Read more →Scalability
The ability of a business to grow revenue significantly without a proportional increase in costs or resources. Highly scalable businesses—often those built on software, platforms, or strong intangible assets—can expand margin as they grow, making them attractive to investors.
Read more →Scalability Premium
The additional value attributed to a business or asset that can grow revenue significantly without a proportional increase in cost. Scalability premiums are characteristic of intangible-heavy businesses — particularly those built on software, data, and network effects — where marginal costs approach zero at scale.
Read more →Scenario Analysis
A valuation and risk assessment technique that evaluates potential outcomes by modelling different sets of assumptions about key variables such as growth rates, margins, and discount rates. Scenario analysis is essential for intangible asset valuation because the future cash flows attributable to intangible assets are inherently uncertain.
Read more →Secondary Buyout
A private equity transaction in which one PE fund sells a portfolio company to another PE fund, rather than to a strategic buyer or through an IPO. Secondary buyouts have become the most common PE exit route, accounting for over 50% of European PE exits in recent years. Critics argue that secondary buyouts merely transfer assets between financial sponsors without creating fundamental value, while proponents note that different fund strategies (e.g., growth equity to buyout, or small-cap to mid-cap) can unlock additional value at each stage.
Read more →Secondary Market (Private Shares)
A marketplace where existing shareholders in private companies — typically employees, early investors, or founders — can sell their ownership stakes to new buyers before an IPO or trade sale. Secondary markets for private shares have grown significantly, with platforms such as Forge Global and Nasdaq Private Market facilitating transactions that provide liquidity and price discovery for otherwise illiquid private company equity.
Read more →Secondary Sale
A transaction in which existing shareholders sell their equity to new investors rather than the company issuing new shares. Secondary sales provide liquidity to founders and early investors without diluting other shareholders or changing the company's capitalisation.
Read more →Seed Round
The earliest formal round of equity financing, typically used to fund product development, initial hiring, and market validation. Seed rounds are usually raised from angel investors, seed funds, or accelerators, with investment sizes ranging from tens of thousands to several million pounds.
Read more →Senior Secured Debt
Debt that holds the highest priority claim on specified collateral in the event of default or liquidation, ranking ahead of unsecured and subordinated obligations. Senior secured lenders benefit from security interests over identified assets such as property, equipment, receivables, or intellectual property. In leveraged finance, senior secured debt typically offers the lowest interest rates in the capital structure due to its priority position and collateral backing.
Read more →Sensitivity Analysis
A method of testing how changes in individual assumptions — such as discount rate, growth rate, or royalty rate — affect the estimated value of an asset or business. Sensitivity analysis is a critical component of intangible asset valuation, revealing which inputs have the greatest impact on the result and informing risk assessment.
Read more →Series A / B / C
Sequential rounds of venture capital financing that follow the seed stage. Series A typically funds scaling after product-market fit; Series B accelerates growth and market expansion; Series C and beyond fund further scaling, internationalisation, or pre-IPO preparation. Each round is usually larger and at a higher valuation.
Read more →Serviceable Addressable Market (SAM)
The portion of the total addressable market that a company can realistically serve given its current product, business model, and geographic reach. SAM is a more practical measure of near-term opportunity than TAM. SAM analysis is a critical input in business valuations and investor due diligence, as it defines the realistic revenue ceiling against which growth projections and market penetration assumptions are tested.
Read more →Shareholders' Agreement
A legally binding contract between a company's shareholders that governs their rights, obligations, and the rules for key decisions including share transfers, board composition, dividend policy, and exit mechanisms. Essential governance infrastructure for investor-backed companies.
Read more →Size Premium
An additional return demanded by investors for holding the equity of smaller companies, reflecting the empirically observed tendency for small-capitalisation stocks to earn higher returns than predicted by the Capital Asset Pricing Model alone. Size premiums are commonly sourced from the Duff & Phelps (now Kroll) Cost of Capital Navigator and are added to the cost of equity in the build-up method or as a modification to CAPM. The existence and magnitude of the size premium remain subjects of academic debate.
Read more →Smart Contract
A self-executing program stored on a blockchain that automatically enforces the terms of an agreement when predetermined conditions are met, without requiring intermediaries. Smart contracts enable trustless transactions, automated escrow, decentralised finance protocols, and programmable business logic. They represent a significant category of technology intangible asset, with value derived from the efficiency gains, disintermediation, and new business models they enable.
Read more →Social Capital
The value created through social relationships, networks, and trust within and between organisations. Social capital facilitates knowledge transfer, collaboration, and collective action, and is increasingly recognised as a measurable intangible asset that influences innovation, productivity, and organisational resilience.
Read more →Social Value
The quantification of the broader social, economic, and environmental impact created by an organisation's activities beyond direct financial returns. Social value encompasses outcomes such as job creation, community development, environmental improvement, health and wellbeing benefits, and reduction of inequality. In the United Kingdom, the Social Value Act 2012 requires public sector commissioners to consider social value in procurement decisions, creating a direct link between social impact and commercial opportunity. From an intangible asset perspective, an organisation's capacity to generate social value is itself an intangible asset — it builds brand equity, strengthens stakeholder relationships, attracts purpose-driven talent, and increasingly influences investor decisions through ESG frameworks. Companies that can demonstrate measurable social value creation often achieve premium valuations, as investors recognise the long-term commercial benefits of strong community and environmental relationships.
Read more →Software Capital
The value embedded in a company's proprietary software assets, including applications, platforms, tools, and codebases. Software capital is a major intangible asset category that drives automation, scalability, and competitive differentiation in technology-enabled businesses.
Read more →Solow Residual
The portion of economic output growth that cannot be explained by measurable increases in labour and capital inputs, named after economist Robert Solow. The Solow residual is often interpreted as a measure of technological progress and is closely related to total factor productivity, capturing the output gains attributable to intangible factors such as innovation, education, and institutional quality.
Read more →Solvency II
The EU regulatory framework for insurance and reinsurance companies, establishing risk-based capital requirements, governance standards, and supervisory reporting obligations. Solvency II uses a three-pillar structure: quantitative requirements (Pillar 1), governance and risk management (Pillar 2), and disclosure and transparency (Pillar 3). In the UK, Solvency UK is the post-Brexit successor regime.
Read more →SOX Compliance
Adherence to the requirements of the Sarbanes-Oxley Act of 2002 (SOX), US federal legislation mandating rigorous financial reporting, internal controls, and audit standards for publicly traded companies. SOX Section 302 requires CEO/CFO certification of financial statements, while Section 404 mandates annual assessment of internal controls over financial reporting.
Read more →Specific Company Risk Premium
An additional return added to the cost of equity to reflect idiosyncratic risks unique to the subject company that are not captured by beta, the equity risk premium, or the size premium. Common factors justifying a specific company risk premium include customer concentration, key person dependence, regulatory exposure, limited product diversification, geographic concentration, and early-stage business risk. Quantification requires professional judgement and should be supported by documented analysis.
Read more →Springing Lien
A security interest that becomes effective only upon the occurrence of a specified trigger event, such as a covenant breach, a decline in borrower creditworthiness, or the drawing down of a revolving credit facility beyond a certain threshold. Springing liens provide lenders with additional collateral protection when needed while allowing borrowers to operate without encumbered assets during normal business conditions. They are commonly used in asset-based lending and revolving credit facilities.
Read more →SPV (Special Purpose Vehicle)
A separate legal entity created for a specific financial purpose, such as isolating risk, holding assets, or facilitating a particular investment. SPVs are commonly used in venture capital for individual deal syndication and in private equity for structuring leveraged acquisitions.
Read more →Step Acquisition
A business combination achieved in stages, where the acquirer held a previously existing equity interest in the acquiree before obtaining control. Under IFRS 3 and ASC 805, the acquirer must remeasure its previously held equity interest at fair value at the acquisition date and recognise any resulting gain or loss in profit or loss. The total consideration for goodwill calculation purposes includes both the fair value of the newly transferred consideration and the remeasured fair value of the previously held interest.
Read more →Structural Capital
The intangible value embedded in an organisation's systems, processes, policies, databases, and intellectual property that remains after employees leave. Structural capital is a subset of intellectual capital and represents the codified knowledge infrastructure that enables repeatable, scalable operations.
Read more →Subordinated Debt
Debt that ranks below senior obligations in priority of repayment in the event of the borrower's liquidation or default. Subordinated debt holders are repaid only after senior secured and senior unsecured creditors have been satisfied in full. Because of its higher risk profile, subordinated debt commands a higher interest rate and is frequently used as a component of leveraged buyout financing, often alongside senior debt and equity.
Read more →Subscription Economy
An economic model in which businesses generate recurring revenue by providing ongoing access to products or services rather than one-time sales. The subscription economy elevates the importance of intangible assets such as customer relationships, brand trust, and product stickiness, which together determine retention and lifetime value.
Read more →Sum-of-the-Parts Valuation
A valuation methodology that determines the total value of a diversified company by independently valuing each business segment, product line, or asset category and aggregating the results. Sum-of-the-parts analysis is particularly useful when a conglomerate's divisions operate in different industries with distinct risk profiles, growth rates, and comparable company sets.
Read more →Sunk Cost
An expenditure that has already been incurred and cannot be recovered, regardless of future decisions. While sunk costs should not influence forward-looking investment decisions, the accumulated effect of past intangible investments — in R&D, brand building, and organisational development — creates the stock of intangible capital that drives future value.
Read more →Supply Chain Finance
A set of technology-based financing solutions that optimise cash flow by enabling suppliers to receive early payment of their invoices at a discount, funded by a financial institution or platform, while the buyer retains its original payment terms. Supply chain finance (also known as reverse factoring) benefits all parties: suppliers improve working capital, buyers extend payment terms without damaging supplier relationships, and financiers earn a return backed by the buyer's credit quality.
Read more →Survival Curve
A graphical representation showing the proportion of an asset population that remains in service over time, plotted from 100% at inception to 0% at the end of the longest-surviving unit's life. Survival curves are used in intangible asset valuation to model the expected decay pattern of customer relationships, subscriber bases, and other wasting intangibles. The shape of the curve — whether concave, convex, or S-shaped — significantly affects the present value of expected future cash flows.
Read more →Switching Costs
The financial, operational, or psychological costs a customer incurs when changing from one product or service to another. High switching costs create customer lock-in and are a powerful intangible competitive moat, particularly in enterprise software, banking, and platform businesses.
Read more →Syndicate
A group of investors who co-invest together in a single funding round, typically organised by a lead investor. Syndicates spread risk across multiple investors and allow companies to access a broader range of expertise, networks, and follow-on capital. Syndicates are commonly used in transactions involving intangible-rich companies, where the investment required to develop intellectual property, build brand awareness, and establish market position may exceed any single investor's risk appetite.
Read more →Synergy Value
The additional value created when two businesses combine that neither could achieve independently. Synergy value arises from cost savings, revenue enhancements, or operational efficiencies post-merger, and is a key driver of acquisition premiums. Under IFRS 3 and ASC 805, synergies are typically subsumed within goodwill rather than recognised as a separate intangible asset.
Read more →Synthetic Data
Artificially generated data that mimics the statistical properties of real-world datasets, used to train machine learning models when actual data is scarce, sensitive, or expensive to obtain. Synthetic data enables AI development in privacy-constrained domains such as healthcare and finance, while reducing data acquisition costs and regulatory exposure.
