Key Terms

in kind, pecuniary interest, immediately convertible, redemption requests

4 terms

in kind financial

"Shares distributed in kind by Rosalind Opportunities Fund I L.P."

Payment, distribution, or transfer made with assets or goods rather than cash, such as shares, property, bonds, or inventory. It matters to investors because receiving or giving value in kind affects liquidity, valuation, record-keeping, and tax treatment—similar to getting a basket of apples instead of cash for a tree: you own something real but may need to convert, value, or manage it differently than money.

pecuniary interest financial

"except to the extent of his or its respective pecuniary interest"

immediately convertible financial

"is immediately convertible"

redemption requests financial

"in satisfaction of redemption requests"

Redemption requests are investor demands to turn holdings in a fund or redeemable security into cash, effectively asking the issuer or manager to return their invested money. Large or sudden volumes of these requests matter because they can force managers to sell assets quickly, lower the value of remaining investors' holdings, and strain a fund’s ability to meet payouts — like many customers lining up at once to withdraw cash from a bank, potentially causing liquidity problems.
