What drives corporate liquidity? An international survey of cash holdings and lines of credit

We survey chief financial officers from 29 countries to examine whether and why firms use lines of credit versus non-operational (excess) cash for their corporate liquidity. We find that these two liquidity sources are employed to hedge against different risks. Non-operational cash guards against future cash flow shocks in bad times, while credit lines give firms the option to exploit future business opportunities available in good times. Lines of credit are the dominant source of liquidity for companies around the world, comprising about 15% of assets, while less than half of the cash held by companies is held for non-operational purposes, comprising about 2% of assets. Across countries, firms make greater use of lines of credit when external credit markets are poorly developed.     

Credit lines as monitored liquidity insurance: Theory and evidence

We propose a theory of credit lines provided by banks to firms as a form of monitored liquidity insurance. Bank monitoring and resulting revocations help control illiquidity-seeking behavior of firms insured by credit lines. The cost of credit lines is thus greater for firms with high liquidity risk, which in turn are likely to use cash instead of credit lines. We test this implication for corporate liquidity management by identifying exogenous shocks to liquidity risk of firms in corporate bond and equity markets. Firms experiencing increases in liquidity risk move out of credit lines and into cash holdings.     

What determines the composition of a firm's cash reserves?

We investigate what determines variation in the composition of the financial assets that constitute corporate cash reserves and how this variation relates to other key liquidity management practices. The degree to which a firm invests its cash reserves in less liquid, longer-maturity financial assets that earn a higher yield is explained by financial constraints, the ability to accurately forecast short-term liquidity needs, and the firm's likelihood of defaulting on its debt. During years when a firm's cash reserves are required to fund increases in investment or operating expenses the firm transfers funds from less liquid to more liquid financial assets. A firm's decisions relating to the composition of its cash reserves interacts with other key liquidity management practices, such as relying on credit lines for liquidity, extending trade credit or using it as a source of financing, and holding large amounts of inventories. Our findings provide insights on an important component of corporate liquidity management decisions.     

Information Asymmetry and Corporate Liquidity Management: Evidence from Real Estate Investment Trusts

We examine the impact of information asymmetry on a firm??s choice between cash and credit lines for corporate liquidity management using a panel data set from real estate investment trusts (REITs). Information asymmetry, as measured by analyst forecast error and dispersion, is negatively related to the use of lines of credit. Specifically, firms with more severe information asymmetry are less likely to have access to bank credit lines. Concurrently, more transparent firms are more likely to utilize bank credit lines as opposed to cash for liquidity management. The results are robust to alternative information asymmetry proxies and specifications. These findings suggest that information asymmetry plays an important role in corporate liquidity management.     

Internal liquidity risk in corporate bond yield spreads

The recent global financial crisis reveals the important role of internal liquidity risk in corporate credit risk. However, few existing studies investigate its effects on bond yield spreads. Panel data for the period from year 1993 through 2008 show that corporate internal liquidity risk significantly impacts bond yield spreads (and changes) when controlling for well-known bond yield determinant variables, traditional accounting measures of corporate debt servicing ability, cash flow volatility, credit ratings, and state variables. This finding indicates that internal liquidity risk should therefore be incorporated into bond yield spread modeling.     

Labor Unions and Forms of Corporate Liquidity

We examine how the presence of labor unions affects a firm's choice of corporate liquidity between bank lines of credit and corporate cash holdings. We find that firms in industries with higher unionization rates hold a higher fraction of corporate liquidity in the form of bank lines of credit. We divide the firms into sub‐groups and find that this positive relationship holds for firms that are not in a state with right‐to‐work legislation and for firms that are financially constrained. Our findings are consistent with the hypothesis that a firm chooses the forms of corporate liquidity to take advantage of the bargaining benefits associated with bank lines of credit.     

Aggregate Risk and the Choice between Cash and Lines of Credit

Banks can create liquidity for firms by pooling their idiosyncratic risks. As a result, bank lines of credit to firms with greater aggregate risk should be costlier and such firms opt for cash in spite of the incurred liquidity premium. We find empirical support for this novel theoretical insight. Firms with higher beta have a higher ratio of cash to credit lines and face greater costs on their lines. In times of heightened aggregate volatility, banks exposed to undrawn credit lines become riskier; bank credit lines feature fewer initiations, higher spreads, and shorter maturity; and, firms’ cash reserves rise.     

Tenant Quality and REIT Liquidity Management

Property values depend upon quality tenants and consistency (Smith: The RMA Journal 50-60, 2009). REIT firms are only as strong as their properties. In this research I examine how tenant quality affects REIT firm liquidity management (i.e. cash holdings and utilization of line of credit). I find that 1) tenant Altman Z-score and size are inversely related to total liquidity (cash plus unused credit line) and unused credit lines of REIT firms; 2) tenant size is inversely related to the total corporate liquidity and unused credit lines of REIT firms, but has no affect on REIT cash holdings; 3) tenant credit ratings are negatively related to total credit available and unused credit lines; 4) tenant book-to-market ratio and tenant profitability are negatively related to REIT cash holdings, but positively correlated to the total available credit lines and unused credit lines of REIT firms; 5) these effects vary across different property types. These results suggest that the analysis of tenant quality can offer insights into the firm policy and decision makings of REIT firms.     

Liquidity mergers

We study the interplay between corporate liquidity and asset reallocation. Our model shows that financially distressed firms are acquired by liquid firms in their industries even in the absence of operational synergies. We call these transactions “liquidity mergers,” since their purpose is to reallocate liquidity to firms that are otherwise inefficiently terminated. We show that liquidity mergers are more likely to occur when industry-level asset-specificity is high and firm-level asset-specificity is low. We analyze firms' liquidity policies as a function of real asset reallocation, examining the trade-offs between cash and credit lines. We verify the model's prediction that liquidity mergers are more likely to occur in industries in which assets are industry-specific, but transferable across firms. We also show that firms are more likely to use credit lines (relative to cash) in industries in which liquidity mergers are more frequent.     

Firms as liquidity providers: Evidence from the 2007–2008 financial crisis

Using a supplier–client matched sample, we study the effect of the 2007–2008 financial crisis on between-firm liquidity provision. Consistent with a causal effect of a negative shock to bank credit, we find that firms with high precrisis liquidity levels increased the trade credit extended to other corporations and subsequently experienced better performance as compared with ex ante cash-poor firms. Trade credit taken by constrained firms increased during this period. These findings are consistent with firms providing liquidity insurance to their clients when bank credit is scarce and offer an important precautionary savings motive for accumulating cash reserves.     

Corporate cash holdings and CEO compensation incentives

We examine the effect of chief executive officer (CEO) compensation incentives on corporate cash holdings and the value of cash to better understand how compensation incentives designed to enhance the alignment of manager and shareholder interests could influence stockholder-bondholder conflicts. We find a positive relation between CEO risk-taking (vega) incentives and cash holdings, and we find a negative relation between vega and the value of cash to shareholders. The negative effect of vega on the value of cash is robust after controlling for corporate governance, is stronger in firms with high leverage, is reversed for unlevered firms, and is not present in financially constrained firms. We also find that the likelihood of liquidity covenants in new bank loans is increasing in CEO vega incentives. Our evidence primarily supports the costly contracting hypothesis, which asserts that bondholders anticipate greater risk-taking in high vega firms and, therefore, require greater liquidity.     

Market Value of REIT Liquidity

We examine the relation between firm value and liquidity among REITs. Results show shareholders benefit from both cash and unused credit line capacity. The market values an additional dollar of cash at a premium and, as theory predicts, unused credit lines are significantly less valued than cash. Evidence suggests an increase in the market value of liquidity during the recent financial crisis. We also find that financial characteristics quantifying financial constraint influence the value of REIT financial flexibility. Most notably, the value of cash decreases with remaining credit line capacity. Although prior studies argue that cash and credit lines are substitutes, this is one of the first tests of whether the market prices this substitutability.     

Coinsurance effect and bank lines of credit

The coinsurance effect hypothesis predicts that firm diversification reduces financial constraints through imperfectly correlated cash flows among segments. We empirically test the hypothesis by studying the relation between coinsurance effect and bank lines of credit. We find that coinsurance effect is associated with a higher availability of bank lines of credit, and that diversified firms hold a higher level of bank lines of credit if they have higher investment opportunities and if they are bank-dependent. We find that diversified firms hold a higher fraction of corporate liquidity in the form of bank lines of credit due to the coinsurance effect. The findings are consistent with the coinsurance effect hypothesis and contribute to the debate on the value consequence of firm diversification by disclosing a specific channel through which firm diversification affects financial constraints.     

Funding Liquidity without Banks: Evidence from a Shock to the Cost of Very Short‐Term Debt

In 2011, Colombia instituted a tax on repayment of bank loans, which increased the cost of short‐term bank credit more than long‐term credit. Firms responded by cutting short‐term loans for liquidity management purposes and increasing the use of cash and trade credit. In industries in which trade credit is more accessible (based on U.S. Compustat firms), we find substitution into accounts payable and little effect on cash and investment. Where trade credit is less available, firms increase cash and cut investment. Thus, trade credit provides an alternative source of liquidity that can insulate some firms from bank liquidity shocks.     

A theory of corporate financial decisions with liquidity and solvency concerns

This paper studies the impact of both liquidity and solvency concerns on corporate finance. I present a tractable model of a firm that optimally chooses capital structure, cash holdings, dividends, and default while facing cash flows with long-term uncertainty and short-term liquidity shocks. The model explains how changes in solvency affect liquidity and also how liquidity concerns affect solvency via capital structure choice. These interactions result in a dynamic cash policy in which cash reserves increase in profitability and are positively correlated with cash flows. The optimal dividend distributions implied by the model are smoothed relative to cash flows. I also find that liquidity concerns lead to a decrease of dispersion of credit spreads.     

Credit and liquidity components of corporate CDS spreads

This paper investigates the role of credit and liquidity factors in explaining corporate CDS price changes during normal and crisis periods. We find that liquidity risk is more important than firm-specific credit risk regardless of market conditions. Moreover, in the period prior to the recent “Great Recession” credit risk plays no role in explaining CDS price changes. The dominance of liquidity effects casts serious doubts on the relevance of CDS price changes as an indicator of default risk dynamics. Our results show how multiple liquidity factors including firm specific and aggregate liquidity proxies as well as an asymmetric information measure are critical determinants of CDS price variations. In particular, the impact of informed traders on the CDS price increases when markets are characterised by higher uncertainty, which supports concerns of insider trading during the crisis.     

Real asset liquidity,cash holdings,and the cost of corporate debt

We study the impact of the interplay between cash holdings and asset sales on the corporate debt spread. We allow cash holdings and asset sales to assist with both debt repayment and sequential investments. The interplay between cash holdings and asset sales leads to a convex relationship between credit spreads and the liquidity of the market for real assets. We use the 2008 financial crisis as a natural experiment and find that post-2008, the nonlinearity of the link between credit spreads and asset liquidity is pronounced, closely matching analytical predictions. This is especially acute for highly leveraged and low profitability firms.     

A Unified Theory of Tobin's q,Corporate Investment,Financing, and Risk Management

We propose a model of dynamic investment, financing, and risk management for financially constrained firms. The model highlights the central importance of the endogenous marginal value of liquidity (cash and credit line) for corporate decisions. Our three main results are: (1) investment depends on the ratio of marginal q to the marginal value of liquidity, and the relation between investment and marginal q changes with the marginal source of funding; (2) optimal external financing and payout are characterized by an endogenous double‐barrier policy for the firm's cash‐capital ratio; and (3) liquidity management and derivatives hedging are complementary risk management tools.     

A Note on Capital IQ's Credit Line Data

Empirical work in finance is increasingly using Capital IQ's detailed data on capital structure. We compare the Capital IQ credit line data to hand‐collected data for a random sample of firms. Missing values in Capital IQ are prevalent, so the data set underreports the importance of corporate credit lines. When data are reported, Capital IQ often differs from hand‐collected credit line activity. We suggest methods for correcting the errors in the Capital IQ data, note which portions of the data are most reliable, and quantify the effects of Capital IQ's underreporting by examining the tradeoff between cash and lines of credit.     

How do firms learn? Evidence from corporate cash holdings during the COVID-19 pandemic

We examine the impact of COVID-19 on US corporate cash holdings. Our findings suggest that greater pandemic exposure is associated with higher corporate cash holdings and that firms learn from prior experiences as they manage their cash policies. More specifically, the level of cash holdings in firms that experienced severe financial constraints during the 2008 credit crisis and firms with prior severe acute respiratory syndrome (SARS) and H1N1 exposure is significantly lower than that of firms with no prior epidemic or financial constraints experience. Overall, our findings support the learning behaviour of cash and contribute to corporate cash holdings literature by providing insights on the extent to which firms learn from prior experiences to manage their liquidity.
