Banks and other financial institutions raise hybrid capital as part of their risk capital. Hybrid capital has no maturity, but, similarily to most corporate debt, includes an embedded issuer's call option. To obtain acceptance as risk capital, the first possible exercise date of the embedded...

We develop a mathematical proof demonstrating that only financially-strong firms will sell put options on their own stock, but financially-weak firms will not. The sale of options on a company's own stock exposes the buyer to default risk of the issuer, which additionally complicates the payoff...

There is a link between barrier options and tax shields of interest expense. We combine this link with a traditional valuation approach, to present practical valuation formulas for interest tax shields in three debt scenarios with risk of default: (1) constant debt, (2) delayed debt, and (3)...

Based on the works of Brockman and Turtle (2003) and Giesecke (2004), we propose in this study a hybrid barrier option model to explain observed credit spreads. It is free of problems with the structural model which underprescribed credit spreads for investment grade corporate bonds and...

This paper presents new closed form solutions for the valuation of European put options and of "down-an-in" barrier options written on leveraged equity. Unlike in past literature (Toft and Prucyk, 1997) and in keeping with empirical evidence, the model allows equity to retain value even after...

We present a model for pricing credit risk protection for a limited liability non-life insurance company. The protection is typically provided by a guaranty fund. In the case of continuous monitoring, i.e., where the market values of the company's assets and liabilities are continuously...

Existing dynamic capital structure models are based on single triggers determining bankruptcy, mainly over-indebtedness or illiquidity. The latter one tends to underestimate optimal capital structures by ignoring capital providers' flexibility to inject fresh money. The former one leans towards...

The value premium is the empirical observation that low market/book “value” stocks have higher returns than high market/book “growth” stocks. In this paper, we investigate and present evidence for an “equity as a call option hypothesis” for the value premium. Volatility decreases the...

Scholars and policymakers now debate reforms that would prevent a bankruptcy filing from being a moment that forces valuation of the firm, crystallization of claims against it, and elimination of junior stakeholders' interest in future appreciation in firm value. These reforms have many names,...

Over-allotment arrangements are nowadays part of almost any initial public offering. The underwriting banks borrow stocks from the previous shareholders to issue more than the initially announced number of shares. This is combined with the option to cover this short position at the issue price....
