On a NYLL wage claim, such as this one, an award of prejudgment interest is mandatory. Prior to 2011, the source of that statutory right was Section. 5001 of New York’s Civil Practice Law and Rules, which provides that prejudgment “[interest shall be recovered upon a sum awarded ... because of an act or omission depriving or otherwise interfering with title to, or possession or enjoyment of, property.”' N.Y.C.P.L.R. § 5001(a) ; see Santillan v. Henao, 822 F.Supp.2d 284, 298 (E.D.N.Y.2011) (“Section 5001 of New York’s Civil Practice Law and Rules governs the calculation of prejudgment interest for violations of the state’s Labor Law.”); see also Mallis, 111 F.2d at 693-94 (<HOLDING>). Effective April 9, 2011, New York also
