15 terms starting with L, from a glossary of 559 definitions covering intangible assets, valuations, and key financial concepts.
Labour Productivity
The amount of output produced per unit of labour input, commonly measured as gross value added (GVA) divided by labour costs or number of employees. Labour productivity is a key efficiency metric that reflects the quality of human capital, processes, and technology deployed by a firm.
Read more →Labour Share of Income
The proportion of national or firm-level income paid to workers as compensation, as opposed to returns on capital. The declining labour share observed in many advanced economies is partly attributed to the growing role of intangible capital, which tends to be more scalable and generates higher returns for capital owners.
Read more →Large Language Model
A type of neural network trained on vast corpora of text data, capable of generating human-like text, answering questions, summarising documents, and performing reasoning tasks. Large language models such as GPT and Claude represent significant R&D investment and are reshaping knowledge work, customer service, and content production across industries.
Read more →Lead Investor
The investor who takes the primary role in a financing round, typically investing the largest amount, setting the terms, negotiating the term sheet, and conducting due diligence. The lead investor often takes a board seat and serves as the main point of contact for the company.
Read more →Lending Against IP
The practice of providing loan facilities secured against intellectual property assets, used interchangeably with IP-backed lending in most contexts. Lending against IP represents a fundamental shift in how financial institutions assess creditworthiness and collateral suitability, moving beyond traditional tangible asset security to recognise the economic value embodied in patents, trademarks, copyrights, trade secrets, and proprietary technology. The practice requires specialist capabilities across three domains: IP valuation (determining the fair value and liquidation value of the IP portfolio), IP legal due diligence (confirming ownership, enforceability, encumbrances, and remaining useful life), and IP monitoring (tracking the ongoing value and condition of the collateral throughout the loan term). In the UK, lending against IP is offered by specialist programmes at NatWest (GBP 250K to GBP 5M), HSBC Innovation Banking (GBP 500K to GBP 10M), and through British Business Bank-supported schemes. The global market for IP-backed finance is estimated to exceed GBP 100 billion by 2027, driven by the increasing share of intangible assets in corporate value and the development of standardised valuation frameworks.
Read more →Leverage Ratio
A financial metric measuring the proportion of debt in a company's capital structure relative to its earnings, equity, or assets. The most common leverage ratios in corporate finance and lending include net debt to EBITDA, debt to equity, and debt to total assets. Leverage ratios are central to loan covenants, credit ratings, and acquisition financing assessments, with maximum permitted levels typically specified in loan agreements and monitored quarterly.
Read more →Leveraged Buyout (LBO)
An acquisition in which a significant proportion of the purchase price is funded by debt, using the target company's assets and cash flows as collateral. LBOs are a common private equity strategy for acquiring mature, cash-generative businesses. In LBO transactions, the quality of a target company's intangible assets — including brand equity, customer relationships, and proprietary technology — directly influences debt capacity, as lenders assess the sustainability of cash flows generated by these assets.
Read more →Licensing Agreements
Contracts that grant permission to use intellectual property (patents, trademarks, software, content) in exchange for fees or royalties. Licensing is both a monetisation strategy for IP owners and an intangible asset for licensees who gain access to proprietary technology or brand rights.
Read more →Limited Partner (LP)
An investor in a private equity or venture capital fund who contributes capital but does not participate in day-to-day investment management. LPs include pension funds, endowments, family offices, sovereign wealth funds, and high-net-worth individuals. LPs increasingly evaluate fund managers on their ability to create intangible asset value within portfolio companies, recognising that intellectual property development, brand building, and customer relationship management are primary drivers of investment returns.
Read more →Liquidation Preference
A term in a venture capital or private equity investment that determines the order and amount in which investors are paid before other shareholders in a liquidation event (sale, wind-down, or IPO). Common structures include 1x non-participating and 1x participating preferences.
Read more →Loan-to-Value Ratio (LTV)
The ratio of a loan amount to the appraised value of the underlying collateral, expressed as a percentage. LTV is a primary risk metric used by lenders to assess the adequacy of collateral coverage — a lower LTV indicates greater equity cushion and lower credit risk. In intangible asset lending, LTV ratios are typically more conservative (often 30-50%) than for tangible asset-backed facilities, reflecting the greater uncertainty in intangible asset realisability.
Read more →Lock-In Effect
The economic phenomenon whereby customers face significant costs, inconvenience, or barriers when attempting to switch from one product, service, or platform to a competitor, effectively binding them to their current provider. Lock-in can arise from contractual obligations, proprietary data formats, integration dependencies, learning curves, or network effects. High lock-in increases customer lifetime value and reduces churn, making it a significant contributor to the value of customer relationship and technology intangible assets.
Read more →Locked Box Mechanism
A pricing mechanism in M&A transactions where the purchase price is fixed based on a set of accounts prepared at a specified date prior to completion, with value leakage protections to ensure no value is extracted from the target between the locked box date and closing. Locked box mechanisms provide price certainty and avoid the disputes often associated with completion accounts adjustments.
Read more →Logo Retention
The percentage of customers (measured by count, not revenue) that remain active over a given period, regardless of changes in their contract value. Logo retention — also called customer retention rate or gross retention by customer count — isolates the frequency of customer loss from revenue expansion or contraction and is a key indicator of product-market fit and customer satisfaction.
Read more →Lookback Provision
A clause in a private equity or venture capital fund agreement that adjusts the distribution of carried interest at the end of the fund's life to ensure the general partner has not received more carry than entitled based on overall fund performance. Lookback provisions protect limited partners against early distributions that overstate returns.
