TL;DR: In this article, the authors examine whether information about firms' directors' and officers' (D&O) liability insurance coverage provides insights into the likelihood of shareholder lawsuits and find evidence that firms with D&O insurance coverage are more likely to be sued.
Abstract: We examine whether information about firms' directors' and officers' (D&O) liability insurance coverage provides insights into the likelihood of shareholder lawsuits. Using Canadian firms, we find evidence that firms with D&O insurance coverage are more likely to be sued and that the likelihood of litigation increases with increased coverage. These findings are consistent with managerial opportunism or moral hazard related to the insurance purchase decision. We also find that higher premiums are associated with the likelihood of litigation, indicating that insurers price this behavior. Taken together, the findings suggest that coverage and premium levels have the potential to convey information about lawsuit likelihood, and a firm's governance quality, to the marketplace.

TL;DR: Higher level of polymorphism and genome-specific amplicons generated by this gene indicated that RPB2 is an excellent tool for investigating the phylogeny and evolutionary dynamics of speciation, and the mode of polyploidy formation in Elymus species.
Abstract: Molecular evolution of the second largest subunit of low copy nuclear RNA polymerase II (RPB2) in allotetrploid StH genomic species of Elymus is characterized here. Our study first reported a 39-bp MITE stowaway element insertion in the genic region of RPB2 gene for all tetraploid Elymus St genome and diploid Pseudoroegneria spicata and P. stipifolia St genome. The sequences on 3′-end are highly conserved, with AGTA in all sequences but H10339 (E. fibrosis), in which the AGTA was replaced with AGAA. All 12 Stowaway-containing sequences encompassed a 9 bp conserved TIRs (GAGGGAGTA). Interestingly, the 5′-end sequence of GGTA which was changed to AGTA or deleted resulted in Stowaway excision in the H genome of Elymus sepcies, in which Stowaway excision did not leave footprint. Another two large insertions in all St genome sequences are also transposable-like elements detected in the genic region of RPB2 gene. Our results indicated that these three transposable element indels have occurred prior to polyploidization, and shaped the homoeologous RPB2 loci in St and H genome of Eymus species. Nucleotide diversity analysis suggested that the RPB2 sequence may evolve faster in the polyploid species than in the diploids. Higher level of polymorphism and genome-specific amplicons generated by this gene indicated that RPB2 is an excellent tool for investigating the phylogeny and evolutionary dynamics of speciation, and the mode of polyploidy formation in Elymus species.
