Global Financial Crisis and Accounting Rules： The Implications of the New Exposure Draft （ED） Financial Instruments： Expected Credit Losses on the Evaluation of Banking Company Loans

During the financial crisis, the delayed recognition of credit losses on loans and other financial instruments was identified as a weakness in existing incurred loss model of impairment stated by International Accounting Standards （IAS） 39, because it is believed that this delay might generate pro-cyclical effects. In response to the recommendations of G20, Financial Crisis Advisory Group （FCAG）, and other international bodies, the International Accounting Standards Board （IASB） has undertaken, since 2009, as a part of the project to replace IAS 39, a project （partially shared with Financial Accounting Standards Board （FASB）） aimed at introducing an expected loss model of impairment. Within the scope of this subset project, the IASB has previously issued two exposure documents proposing models to account for expected credit losses： an exposure draft （ED） Financial Instrument： Amortized Cost and Impairment, published in November 2009, and a supplementary document （SD） Financial Instrument： Impairment, published jointly with the FASB in January 2011. However, neither of the two proposals received strong support from interested parties. Recently, the IASB, after the FASB＇s decision to withdraw from the joint project and to develop a separate expected credit loss model based on a single measurement approach consisting in the sole recognition of lifetime expected credit losses, published a third proposal--Ahe so-called expected credit losses model （ED/2013/3 Financial Instruments： Expected Credit Losses）.

Mandatory Financial Reporting Processes and Outcomes

In an extension to the mandatory financial reporting literature, we consider compliance and applicability as intermediate stages in the disclosure decision process, and investigate to what extent these measures explain any variance in the quantity of disclosure. We use financial instruments disclosures as our empirical context because of the level of complexity and diversity of the mandatory requirements. We find that neither applicability nor compliance show statistically significant association with disclosure quantity. By contrast we find that a firm's financial instruments management programme is an important determinant of both applicability and quantity. Finally, we demonstrate the economic consequences of applicability, compliance and quantity through their association with audit fees. For companies that use financial instruments management programmes to a greater extent, audit fees are higher. In contrast, the quantity of financial instruments disclosures appears to reduce audit fees.

Current Issues in the Economics of Groundwater Resource Management

Abstract.  The issue of groundwater management remains a practical concern in many regions throughout the world, while water managers continue to grapple with the question of how to manage this resource. In this article, we attempt to bring the most advanced and appropriate tools to bear on the issue of resource allocation involving groundwater. Our objective is to demonstrate the state of the art in the literature on ways to think about this complex resource and to deal with the important economic issues emanating from its complexity. We present the conceptual framework within which economists examine the elements interacting in the management of groundwater resources, indicate why the role of the market is limited with respect to the price of this very complex resource, and point to the mechanisms that can pull competitive groundwater price and quality-graded quantity of groundwater in line with their equilibrium levels. In particular, we critically review economic models of groundwater use, examine the potential for groundwater management, discuss the difficulties encountered in the estimation of the relevant control variables of such models, and identify the advantages and limitations of the instruments devised for the efficient use (allocation) of this resource. Finally, we argue that devised regulatory schemes usually ignore the information and knowledge needed for their implementation, and we suggest a core of conditions necessary for successful groundwater management reforms.     

"Marking-to-Market" and Treasury-Bill Futures Prices: Some Empirical Evidence

Financial economists have not found empirical evidence of a “marking‐to‐market” effect in Treasury‐bill futures contracts, despite a firm theoretical basis for its existence. Therefore, we speculate that confounding effects, possibly due to liquidity preferences, influence futures‐forward price spreads. By using an empirical specification that allows for both effects, we present empirical evidence that Treasury‐bill futures‐forward price spreads are sensitive to the volatility of the underlying commodity in ways predicted by the theory of the marking‐to‐market effect.     

A Re-examination of the Case for Accounting Separately for the Debt and Equity Features of Convertible Debt

The case for accounting separately for the debt and equity features of a convertible bond is based on two main assumptions: convertible debt can be decomposed into two, or more, fundamental financial instruments, and a convertible bond has the same economic substance as a bond with a detachable warrant. These assumptions are re-examined in this paper where it is shown that it is generally not possible to decompose a convertible bond into fundamental financial instruments, nor is it possible to form a package of a bond and a detachable warrant that replicates the character of the convertible bond.     

Usefulness of comprehensive income reporting in Canada

In January 2005 the Canadian Accounting Standards Board (AcSB) issued three new accounting standards that require Canadian firms to mark-to-market certain financial assets and liabilities and recognize the holding gains and losses related to these items as other comprehensive income or as part of net income. The Board’s objectives for issuing the new standards are (i) to harmonize Canadian GAAP with US and International GAAP, (ii) to enhance the transparency and usefulness of financial statements, and (iii) to keep pace with changes in accounting standards in other countries that are moving towards fair value accounting. This paper investigates empirically whether requiring Canadian companies to report comprehensive income and its components provides the securities market with incremental value-relevant information over the traditional historical-cost earnings approach.Previous empirical studies provide mixed evidence on the value relevance of other comprehensive income and its components. This mixed evidence may be attributed partially to the use of as if methodology to construct an ex-ante measure of other comprehensive income prior to the implementation of SFAS 130, which introduces measurement error. In contrast, this study uses actual data on other comprehensive income for a sample of Canadian firms cross-listed in the US in the period 1998–2003. We find evidence that available-for-sale and cash flow hedges components are significantly associated with price and market returns. We also find that aggregate comprehensive income is more strongly associated (in terms of explanatory power) with both stock price and returns compared to net income. However, we find that net income is a better predictor of future net income relative to comprehensive income. Our findings suggest that mandating all Canadian firms to adopt the new accounting standards is expected to enhance the usefulness of financial statements. Our findings, therefore, should be of interest to Canadian accounting policy makers as they provide ex-ante evidence on the potential usefulness of mandating firms to report comprehensive income and the components of other comprehensive income in their financial statements.
